- the present invention relates generally to fasteners. More particularly, the present invention relates to closures for garments.
- Personal protective equipment is a general term that refers to various garments, breathing apparatus and monitoring devices that are used by persons potentially exposed to hazardous conditions or environments.
- many employers require employees to wear special apparel, such as coveralls, jackets, trousers, shirts, boots, helmets and gloves, among other things.
- Protective garments are designed to protect the individual wearing the garments by eliminating or reducing daily exposure pathways, such as inhalation of harmful vapors and particulates and percutaneous adsorption of harmful liquids.
- OSHA-mandated personal protective equipment are intended for use against hazards of processes or environment; chemical, biological and radiological hazards; or mechanical irritants encountered in a manner capable of causing injury or impairment in the function of any part of the body through absorption, inhalation or physical contact.
- selection, use, training and programs for personal protective equipment for use by emergency responders may be covered by regulations, standards and recommendations promulgated or issued by the U.S. Environmental Protection Agency (EPA), the U.S. Department of Transportation (DOT), and the National Fire Protection Association (NFPA).

- Protective garments include apparel like coveralls, jackets, trousers, shirts, boots, helmets and gloves. Similar to regular street garments, protective garments typically have closures with fasteners such as buttons, snaps, zippers and hooks and loops (commonly called Velcro®). The closures are provided to facilitate the donning, doffing and safely wearing the garments. However, closures on protective garments may provide pathways for gases, liquids, vapors and, sometimes, particulates to permeate or penetrate the garment and expose the individual wearing the protective garment to harmful substances. That exposure pathway can result in a reduced effectiveness of the protective garment, and the garment may fall out of compliance with personal protective equipment standards.
- closures are often required for functionality, they often introduce undesirable adverse affects when it comes to health and safety.
- Penetration such as through permeation or wicking
- Penetration is a potential adverse affects introduced by providing a closure on a protective garment.
- harmful substances can permeate the otherwise impermeable garment.
- sewn seams are made using stitches, the seam can operate like a wick or carrier which allows the harmful substance to penetrate through to the user.
- those stitches penetrate the garment fabric and create through holes which may also allow gases, liquids and vapors to penetrate from one side of the garment to the other.
- a bound seam is used to encapsulate the raw edges of two plies of fabric. All of the layers are sewn through with a chain stitch that creates a series of closely spaced through holes in the fabric layers. If that area contacts a hazardous liquid, the liquid can penetrate the through hole and volatilize on the inside of the garment, exposing the individual wearing the garment. Likewise, if the individual is working in an environment where hazardous gases or vapors are present, the gases and vapors can also permeate or penetrate the through holes.
- storm flaps are constructed from the primary garment material and lies over the top of the buttons, snaps or zippers and helps keep liquids off those fasteners and the sewn seams. Often the storm flap is secured in place with hook and loop fasteners.
- One problem with storm flaps is that they do not seal the closure devices so they do not prevent permeation of gases and vapors. Also, liquids may get around the storm flap and contact the closure and seams. Thus, the stitches where the closure device is attached to the garment are still exposed and can provide exposure pathways for hazardous materials.
- a taped closure is produced when a closure is covered with a strip of compatible material and attached permanently or temporarily over the closure.
- One problem associated with taped closures is that the garment cannot be donned or doffed easily or in a timely manner because of the extra step of applying or removing the tape to/from the closure. Further, it is often difficult to create a good seal with tape on some closures by manually applying pressure to tape. This is a problem on fabrics that are not free of wrinkles. Moreover, the assistance of another person is often required to install tape on certain closures. For example, a long vertical zipper on the rear of a shirt jacket is nearly impossible to tape by the person wearing the shirt.
- a taped seam is produced by covering a sewn seam with a strip of compatible material.
- the tape may have an adhesive backing, or may further be attached to the garment and/or closure by a laminating process or by heat sealing the tape to the seam with a suitable heat-activated adhesive.
- One problem associated with taped seams is that they cannot be used to cover all seams effectively. Moreover, if a chemical substance penetrates a torn tape seal, it can then easily penetrate the garment through the stitch through holes under the tape just as if the tape were not there.
- zippers which are usually attached to garments with “stringers,” once the stringer material becomes contaminated, the accumulated contamination can penetrate the garment when the individual wearing the garment begins doffing the device. That is, if the individual is not decontaminated before doffing the garment, he or she can be exposed to the accumulated chemicals when he or she opens the fastener.
- Norvell illustrates a water resistant closure for a garment in the form of a zipper attached to a fabric with sewn seams that are covered with water-repellant seam seal tape.
- One problem with the tape seam in Norvell is that if the tape is damaged or the water repellant coating is damaged or deteriorates, water can migrate through the stitch through holes and into the inner surface of the garment.
- U.S. Pat. No. 5,705,251 to Morman et al. disclose a garment for medical practitioners having a porous hydrophobic layer and a spacing layer adjacent to the porous hydrophobic layer.
- the spacing layer forms channels, so that liquid in contact with the spacing layer flows into the channels without passing through the porous hydrophobic layer. Morman, however, does not address the problems associated with closures on protective garments.
- Another object of the present invention is to provide a jacket with a front closure zipper with taped seams and a channel behind the seams with a bottom opening for discharging any materials entering the channel.
- a closure between two longitudinal edges of a garment defining an opening therebetween, in which the closure includes several adjacent layers of fabric materials attached together with stitched seams.
- the garment may be part of a protective garment used to meet personal protective equipment standards.
- first garment layer having an inner and outer surface, wherein one edge of the first garment layer is folder back on itself forming a second garment layer; a fastener, such as a zipper, having a tape portion forming a third layer, wherein a portion of the third layer is adjacent the second garment layer; a fourth garment layer in which an edge of the fourth garment layer is folded back on itself forming a fifth garment layer and wherein the fifth garment layer is adjacent the third layer and the other edge of the fourth garment layer is adjacent the inner surface of the first garment layer.
- Those layers are attached by a stitched seam through the second, fourth and fifth adjacent layers and another stitched seam through the first and fourth adjacent layers.
- a seal tape layer covers the second stitched seam and is attached to the first garment layer and the fourth garment layer by adhesive.
- the resulting garment layers and stitched seams form a longitudinally extending channel that runs substantially parallel the edge of the first garment layer.
- the channel includes an opening on one end (preferably the bottom) for discharging materials inside the channel.
- a receptacle may be used adjacent the opening such that materials discharged from the opening of the channel are discharged into the receptacle.
- the receptacle could be a tube or a pocket.
- the closure also may include a sixth garment layer in the form of a loop, a portion of which is adjacent the outer surface of the first garment layer.
- the closure also may include a third stitched seam through the first and sixth adjacent layers for securing the loop to the first layer.
- the third stitch penetrates the first layer between the first and second stitches.
- the resulting sixth garment layer and stitched seam form a second longitudinally extending channel substantially parallel the first channel.
- the channel may or may not include an opening on one end.
- a fastener such as hooks and loops, buttons, snaps, and zippers, may be attached to the loop.
- a fourth stitched seam may be added through the first and sixth adjacent layers adjacent the third stitched seam for further securing the loop to the first layer. The fourth stitch penetrates the first layer between said first and second stitches.

If the flap 320 is made of a material that is permeable to that liquid, some of the liquid could permeate the material and enter the channel 326 .
- Some of the vapors might condense be discharged from the channel 326 or otherwise be collected or transported out. Some of the vapors could also permeate through the back side of the flap 320 to the front panel 302 . Some of the vapors could then condense on the surface of the front panel 302 and permeate into the channel 121 , 221 , where some of the vapors could condense and be discharged out the bottom of the channel 121 , 221 through the opening 122 (opening 222 in the case of garment 200 ) and into a receptacle 224 .

- the liquid would be blocked by the adhesive 317 and seam seal tape 316 layers.
- the liquid could wick through the through holes formed by the stitches, volatilize inside channel 121 , 221 and eventually be discharged out the opening 122 .
Abstract
A closure for use on protective garments is defined by two oppositely-facing, longitudinally-extending edges of fabric having an opening therebetween as a slide fastener spanning the opening. A longitudinal channel is provided adjacent the fastener and formed by layers of the fabric for collecting and discharging materials out an opening and into an optional receptacle. The channel is formed by folding an outer front panel of the garment back onto itself. The zipper is then stitched to the interior end portion and a patch along a first stitch line. The patch is folded back on itself and the opposite end of the patch is stitched to the outer front panel of the garment along a second stitch line. Seal tape is placed over the second stitch line, thereby forming a sealed channel between the outer layer of the garment and the patch layer between the first stitch line and the second stitch line. Any gases, vapors and liquids that might otherwise penetrate the stitch lines are passed into the channel, and drained away from the user. A flap may also be added over the front of the closure to cover a portion of the fastener and the channel and provide an additional layer of protection.
Description
- 1. Field of Invention
- The present invention relates generally to fasteners. More particularly, the present invention relates to closures for garments.
- 2. Description of the Prior Art
- Many industrial occupations require the use of personal protective equipment. Personal protective equipment is a general term that refers to various garments, breathing apparatus and monitoring devices that are used by persons potentially exposed to hazardous conditions or environments. In the case of protective garments, many employers require employees to wear special apparel, such as coveralls, jackets, trousers, shirts, boots, helmets and gloves, among other things. Protective garments are designed to protect the individual wearing the garments by eliminating or reducing daily exposure pathways, such as inhalation of harmful vapors and particulates and percutaneous adsorption of harmful liquids.
- In certain regulated industries in the United States, the use of certain personal protective equipment is mandated by the Occupational Safety and Health Administration (OSHA). OSHA-mandated personal protective equipment are intended for use against hazards of processes or environment; chemical, biological and radiological hazards; or mechanical irritants encountered in a manner capable of causing injury or impairment in the function of any part of the body through absorption, inhalation or physical contact. Moreover, the selection, use, training and programs for personal protective equipment for use by emergency responders may be covered by regulations, standards and recommendations promulgated or issued by the U.S. Environmental Protection Agency (EPA), the U.S. Department of Transportation (DOT), and the National Fire Protection Association (NFPA).
- Even in non-industrial, non-regulated work places, where traditional industrial work hazards do not pose a potential threat, employers may also mandate the use of certain protective garments in some situations. For example, after anthrax was deployed through the U.S. postal system in the mail, some employers that were not regulated by OSHA, EPA or other federal or state agency began implementing personal protective equipment standards applicable to corporate mail handlers. Moreover, some employers have implemented personal protective equipment standards for insurability purposes even where their industry is not regulated by OSHA or other agency. Implementing those standards may be needed to obtain certain types of insurance coverage or can lower premiums on already existing policies.
- Protective garments include apparel like coveralls, jackets, trousers, shirts, boots, helmets and gloves. Similar to regular street garments, protective garments typically have closures with fasteners such as buttons, snaps, zippers and hooks and loops (commonly called Velcro®). The closures are provided to facilitate the donning, doffing and safely wearing the garments. However, closures on protective garments may provide pathways for gases, liquids, vapors and, sometimes, particulates to permeate or penetrate the garment and expose the individual wearing the protective garment to harmful substances. That exposure pathway can result in a reduced effectiveness of the protective garment, and the garment may fall out of compliance with personal protective equipment standards.
- Thus, while closures are often required for functionality, they often introduce undesirable adverse affects when it comes to health and safety. Penetration, such as through permeation or wicking, is a potential adverse affects introduced by providing a closure on a protective garment. For example, when a closure device is sewn to a protective garment, harmful substances can permeate the otherwise impermeable garment. Where sewn seams are made using stitches, the seam can operate like a wick or carrier which allows the harmful substance to penetrate through to the user. In addition, those stitches penetrate the garment fabric and create through holes which may also allow gases, liquids and vapors to penetrate from one side of the garment to the other.
- For instance, a bound seam is used to encapsulate the raw edges of two plies of fabric. All of the layers are sewn through with a chain stitch that creates a series of closely spaced through holes in the fabric layers. If that area contacts a hazardous liquid, the liquid can penetrate the through hole and volatilize on the inside of the garment, exposing the individual wearing the garment. Likewise, if the individual is working in an environment where hazardous gases or vapors are present, the gases and vapors can also permeate or penetrate the through holes.
- To overcome the problems associated with closure devices with sewn seams and still meet standards for protective garments, some manufacturers have come up with a variety of solutions. On shirt jackets, for example, some manufacturers incorporate so-called “storm” flaps. The storm flap is constructed from the primary garment material and lies over the top of the buttons, snaps or zippers and helps keep liquids off those fasteners and the sewn seams. Often the storm flap is secured in place with hook and loop fasteners. One problem with storm flaps is that they do not seal the closure devices so they do not prevent permeation of gases and vapors. Also, liquids may get around the storm flap and contact the closure and seams. Thus, the stitches where the closure device is attached to the garment are still exposed and can provide exposure pathways for hazardous materials.
- Other manufacturers move the closure to the back of the garment and away from the so-called “strike” or impact zone, which is typically located to the individual's front side. That may reduce certain incidences of exposure due to immersion of the closure and seams by liquids being splashed onto the garment. However, repositioning the closure to the rear of the garment does not necessarily reduce permeation or penetration of chemicals through the closure and seams, such as gases that may be present in the environment.
- Still other manufacturers rely on taped seams and closures. A taped closure is produced when a closure is covered with a strip of compatible material and attached permanently or temporarily over the closure. One problem associated with taped closures is that the garment cannot be donned or doffed easily or in a timely manner because of the extra step of applying or removing the tape to/from the closure. Further, it is often difficult to create a good seal with tape on some closures by manually applying pressure to tape. This is a problem on fabrics that are not free of wrinkles. Moreover, the assistance of another person is often required to install tape on certain closures. For example, a long vertical zipper on the rear of a shirt jacket is nearly impossible to tape by the person wearing the shirt.
- A taped seam is produced by covering a sewn seam with a strip of compatible material. The tape may have an adhesive backing, or may further be attached to the garment and/or closure by a laminating process or by heat sealing the tape to the seam with a suitable heat-activated adhesive. One problem associated with taped seams is that they cannot be used to cover all seams effectively. Moreover, if a chemical substance penetrates a torn tape seal, it can then easily penetrate the garment through the stitch through holes under the tape just as if the tape were not there. Also, in the case of zippers, which are usually attached to garments with “stringers,” once the stringer material becomes contaminated, the accumulated contamination can penetrate the garment when the individual wearing the garment begins doffing the device. That is, if the individual is not decontaminated before doffing the garment, he or she can be exposed to the accumulated chemicals when he or she opens the fastener.
- One example of a tape seam is shown in U.S. Pat. No. 5,386,616 to Norvell. Norvell illustrates a water resistant closure for a garment in the form of a zipper attached to a fabric with sewn seams that are covered with water-repellant seam seal tape. One problem with the tape seam in Norvell is that if the tape is damaged or the water repellant coating is damaged or deteriorates, water can migrate through the stitch through holes and into the inner surface of the garment.
- U.S. Pat. No. 5,705,251 to Morman et al. disclose a garment for medical practitioners having a porous hydrophobic layer and a spacing layer adjacent to the porous hydrophobic layer. The spacing layer forms channels, so that liquid in contact with the spacing layer flows into the channels without passing through the porous hydrophobic layer. Morman, however, does not address the problems associated with closures on protective garments.
- In view of the foregoing, it should be apparent that there exists a need in the art for a garment closure having a combination of seam tape and channels for eliminating or reducing the permeation or penetration of hazardous materials through the garment when it is exposed to hazardous environments.
- It is, therefore, a primary object of the present invention to provide a closure device for protective garments that reduces or eliminates penetration of gases, vapors, liquids and particulates through the closure.
- More particularly, it is an object of the present invention to provide a closure device for a protective garment that is attached to the garment in a manner that prevents penetration of gases, vapors, liquids and particulates from the outside of the garment to the inside via a through hole.
- Still more particularly, it is an object of the present invention to provide a zipper closure with a channel for transporting hazardous materials from the zipper closure to a receptacle.
- Another object of the present invention is to provide a jacket with a front closure zipper with taped seams and a channel behind the seams with a bottom opening for discharging any materials entering the channel.
- It is another object of the present invention to provide a coverall with a front closure zipper with taped seams and a channel behind the seams connected to a drainable receptacle for receiving and discharging any materials entering the channel, or connected to an opening for discharging any materials entering the channel.
- Briefly described, these and other objects and features of the present invention are accomplished, as embodied and fully described herein, by a closure between two longitudinal edges of a garment defining an opening therebetween, in which the closure includes several adjacent layers of fabric materials attached together with stitched seams. The garment may be part of a protective garment used to meet personal protective equipment standards.
- In the preferred embodiment of the closure, there is a first garment layer having an inner and outer surface, wherein one edge of the first garment layer is folder back on itself forming a second garment layer; a fastener, such as a zipper, having a tape portion forming a third layer, wherein a portion of the third layer is adjacent the second garment layer; a fourth garment layer in which an edge of the fourth garment layer is folded back on itself forming a fifth garment layer and wherein the fifth garment layer is adjacent the third layer and the other edge of the fourth garment layer is adjacent the inner surface of the first garment layer. Those layers are attached by a stitched seam through the second, fourth and fifth adjacent layers and another stitched seam through the first and fourth adjacent layers. A seal tape layer covers the second stitched seam and is attached to the first garment layer and the fourth garment layer by adhesive.
- The resulting garment layers and stitched seams form a longitudinally extending channel that runs substantially parallel the edge of the first garment layer. The channel includes an opening on one end (preferably the bottom) for discharging materials inside the channel. A receptacle may be used adjacent the opening such that materials discharged from the opening of the channel are discharged into the receptacle. The receptacle could be a tube or a pocket.
- The closure also may include a sixth garment layer in the form of a loop, a portion of which is adjacent the outer surface of the first garment layer. The closure also may include a third stitched seam through the first and sixth adjacent layers for securing the loop to the first layer. The third stitch penetrates the first layer between the first and second stitches. The resulting sixth garment layer and stitched seam form a second longitudinally extending channel substantially parallel the first channel. The channel may or may not include an opening on one end. A fastener, such as hooks and loops, buttons, snaps, and zippers, may be attached to the loop. A fourth stitched seam may be added through the first and sixth adjacent layers adjacent the third stitched seam for further securing the loop to the first layer. The fourth stitch penetrates the first layer between said first and second stitches.

- Referring now in detail to the drawings, wherein like parts are designated by like reference numerals throughout, there is illustrated in FIG. 1 a perspective view of a
garment 100 according to the present invention. Thegarment 100 is preferably made of three-laminated layers of texturized polyester fabric, such as that sold by the W. L. Gore & Associates company under its three-layer GORE-TEX® brand line. However, other fabrics may also be used, though the fabric should preferably be lightweight, waterproof, permeable to water vapor to ensure adequate breathability, rugged, durable, and cleanable. In other embodiments, the fabric can be non-permeable to vapors and compatible with conventional decontamination compounds. Other types of garment fabrics that may be suitable include NOMEX® and TYVEK®, both available from E.I. du Pont de Nemours and Company. - The
garment 100 illustrated in FIG. 1 is a protective garment for use by persons requiring protection from certain hazards, such as chemical or bio-logical hazardous materials. For example, the three-laminated layers of polyester fabric provides protection from penetration of certain substances from the outside of thegarment 100 to the inside. Thegarment 100 thereby protects the user from coming into contact with undesirable substances. - The
garment 100 has aright sleeve 102, aleft sleeve 104, afront panel 106, a rear panel 108, abottom opening 110, and aneck opening 112. Thefront panel 106 includes separable left and right portions each with respective right and leftedges edges - A

In the embodiment shown in FIG. 1, thefront fastener 120 is a zipper. The zipper has two stringers that are each attached by stitched seams torespective edges - A
channel 121 is formed along each of theedges garment 100, where theclosure 118 attaches to theedges garment 100. The channels extend substantially vertically along thegarment 100. It should be recognized, however, that the channel can also be positioned diagonally or horizontally with respect to thegarment 100, or in any other suitable manner as aclosure 118 might be positionable. In accordance with the preferred embodiment of the invention, the channel extends the entire length of theedges closure 118. Of course, theclosure 118 need not extend the entire length of thegarment 100. - At the base of the
front closure 118 andchannel 121 is anopening 122 where materials entering thechannel 121 behind the closure (FIG. 3) can be discharged. Additionally, a barrier or receptacle could be included to receive or temporarily store materials discharged from theopening 122. One example of a receptacle is shown, for instance, in the embodiment of FIG. 2. - The
neck opening 112 has aneck closure 114, which is shown in the closed position in FIG. 1. Theneck closure 114 may include a fastener (not shown), which may be any fastener, including, but not limited to, a button, a snap, hooks and loops and a slide fastener (such as a zipper). In FIG. 2 there is illustrated a perspective view of a garment 200 which is an overall, in accordance with another preferred embodiment of the present invention. The garment 200 may have the same uses and be made out of the same fabric materials as thegarment 100 shown in FIG. 1. - Accordingly, the garment200 has a
right sleeve 202, aleft sleeve 204, afront panel 206, a rear panel 208 (not visible), aneck opening 212, aright pant leg 226, aleft pant leg 228, andopenings pant legs front panel 206 includes separable left and right portions each with longitudinally-extending, vertically-oriented, substantiallyparallel edges - A
front closure 218 extends from theneck opening 212 at the top of the garment 200 to a position approximately at the top of thepant legs front closure 218 includes afastener 220, which may be any fastener, including but not limited to, a series of spaced buttons or snaps, hooks and loops strips and a slide fastener. In the embodiment shown in FIG. 2, thefront fastener 220 is a zipper. The zipper has two stringers that are attached by stitched seams along theedges - At the base of the
front closure 218 is anopening 222 where materials entering achannel 221 behind the closure (FIG. 3) can be discharged. Additionally, areceptacle 224 could be included to receive or temporarily store materials discharged from theopening 222. The types ofreceptacles 224 include, but are not limited to, hollow cylindrical tubes and cup pockets. Thereceptacle 224 could be located anywhere on the garment 200, but preferably is positioned at theexit opening 222 and is integral to the garment fabric or a separate device secured to the garment 200. - The
neck opening 212 has aneck closure 214, which is shown in the open position in FIG. 2. Theneck closure 214 is the same as theneck closure 114 shown in FIG. 1. Theneck closure 214 includes a fastener 216 (not shown), which may be any fastener, including but not limited to, a button, a snap, hooks and loops and a zipper. - In FIG. 2 the
pant legs openings pant legs - In FIG. 3 there is illustrated a cross sectional view of the
closures edge garments 100, 200 shown in FIGS. 1 and 2, respectively, taken at line 3-3. Theclosures garments 100, 200, from exposure to those substances. The channel is generally represented byreference numeral front panel 302 of thegarment 100, 200, and apatch segment 304. The ends of thefront panel 302 form theedges fastener - The term “penetration” means the physical process by which a substance passes through a material, such as via tears, openings, through holes, or other routes. As used herein, the term penetrate includes any manner in which a substance can pass through a material or membrane, such as by permeation, infiltration, saturation, adsorption, absorption, wicking, diffusion, or osmosis.
- The front closure118 (or front closure 218) includes
front panel 302, the end of which is folded back on itself to form anend section 303. As noted previously, the material used to make thegarments 100, 200 may be a single layer, or a composite having multiple layers. - The
front closure 118 also includes apatch segment 304, which at one end has a portion folded back on itself to form anend section 305. The fastener 120 (or fastener 220) is also shown in FIG. 3 as a zipper. Thefastener 120 is a standard device, and any suitable fastener could be used. Thestandard slide fastener 120 has a slider and a row ofinterlockable elements 308 attached to, or integral with, a connectingpiece 310. The connectingpiece 310 enables thefastener 120 to be connected to thegarment 100. In the present embodiment, the connectingpiece 310 can be a tape or other material. However, the invention can be used with anysuitable closure 118, including buttons and other device which do not include connectingpieces 310. Thus, the use of a connectingpiece 310 is merely illustrative of the invention. - The connecting
piece 310 is a flexible material which may be compatible with the fabric material making up thegarment 100, 200 fabric layers. The connectingpiece 310 is sandwiched between the two reverse-foldedend sections front panel 302 and thepatch segment 304, respectively. Theend sections piece 310 are attached together at afirst connection 312. As shown in FIG. 3, thefirst connection 312 can be any suitable connection, such as stitches forming a sewn seam. Thefirst connection 312 secures the connectingpiece 310, and thereby thefastener 120, to thegarment front panel 302. Thefirst connection 312 also secures thepatch segment 304 to thegarment front panel 302. - The reverse bend of the
end sections connection 312 within thechannel first connection 312 does not allow any undesired substances to penetrate to the inside of the garment, and any undesired substance that reached theconnection 312 would instead enter thechannel end sections channel piece 310 to thefront panel 302 of thegarment 100, 200. Though thefirst connection 312 is shown as a single connection, it should be recognized that more than one connection can be made, such as one connection between thefront panel 302 and the connectingpiece 310, and another connection between thepatch 304 and the connectingpiece 310 and/or thefront panel 302. - A
second connection 314 is then used to attach the opposite end of thepatch layer 304 to the inner surface of thefront panel 302, such as by using stitches to form a sewn seam. Thesecond connection 314 is then covered with a layer ofseal tape 316 to prevent penetration of undesired substances which might otherwise occur through the stitched through holes created by thesecond connection 314. Theseal tape 316 is adhered to the inner surface of thefront panel layer 302 and thepatch layer 304 by a layer of adhesive 317. - The
front panel 302, thepatch 304 and the first and second connect points 312, 314 form ahollow channel channel channel channel channel garment 100, 200. The preferred width of thepatch 304, from the end which is taped 316 to theseam 312, is about 1.7 inches. - Thus, the
channel channel garment 100, 200. For example, some of the liquids collected in thechannel front panel 302 andpatch 304 are permeable, then the volatilized liquid may pass through those layers. - If the fabric is impermeable, then volatilized liquids inside the
channel channel front panel 302 andpatch 304 and then drain out. Or, portions of the channel could be compressed manually or by normal use of thegarment 100, 200, thereby expelling a portion of the volume of vapor-laden gas within thechannel opening 222, in the case of garment 200). Still yet, theopening channel - Alternatively, a
flap 320 can be positioned in front of thechannel slide fastener 120, as further shown in FIG. 3. Theflap 320 can be made of the same or different fabric of the rest of thegarment 100, 200. In the embodiment shown, theflap 320 is in the form of a loop that is sewn to the outside surface of thefront panel layer 302 withstitches hook 325 is made by stitching theflap 320 to thefront panel 302 withstitch 324, folding the loop back on itself and then stitching thestitch 322. Thus, stitches 322, 324 form two spaced apart sewn seams that are generally parallel to each other. - The
stitches channel connection 324 pass into thechannel front panel 302, and thegarment 100, 200 would still prevent the penetration of undesired substances. In that regard, though the invention is preferably provided for afastener 120, thechannel front panel 302 need not be reversely bent, since any undesired substance penetrating thefirst connection 312 will pass into thechannel patch 304 at thefirst connection 312, and thepatch 304 need not be reversely bent. Moreover, theseal tape 316 need not be provided, and instead the end of thepatch 304 can be reversely bent. - The
flap 320 loop forms asecond channel 326. On the outer face of theflap 320 is afastener 328. In the embodiment shown in FIG. 3, thepreferred fastener 326 is a hooks and loops-type fastener (only the hooks are shown, the corresponding loops are attached to the opposite side of the garment front panel 106). However, other fasteners are also contemplated. - The front closure118 (and front closure 218) works as follows. In an environment where a person wearing the
garment 100 is exposed to an undesired substance, such as due to splashing, immersion, or condensation of a liquid, at the front of thegarment 100, the substance would contact thefront panel layer 302 and/or theflap 320 covering thefront closure 118. If theflap 320 is made of a material that is permeable to that liquid, some of the liquid could permeate the material and enter thechannel 326. - Some of the vapors might condense be discharged from the
channel 326 or otherwise be collected or transported out. Some of the vapors could also permeate through the back side of theflap 320 to thefront panel 302. Some of the vapors could then condense on the surface of thefront panel 302 and permeate into thechannel channel receptacle 224. If thegarment 100 includes areceptacle 224 in the form of a barrier or cup pocket, the materials discharged to thatreceptacle 224 may be emptied and handled by conventional means following any applicable environmental, health and safety standards for such handling and disposal. - If the materials making up the
flap 320, thefront panel layer 302 and thepatch layer 304 are impermeable to liquids, then a liquid chemical striking thefront closures channels - In addition to the above, an undesired substance that is splashed, immersed, or condensed onto the front of the
garment 100 could wick through the seams and stitches 312, 314, 322 and 324. In the case ofstitch 312, for example, a liquid could migrate between the fabric layers along the seam formed by thestitch 312, then wick through thestitch 312 and volatilize into thechannel stitch 312. In the case ofstitch 314, the liquid would be blocked by the adhesive 317 andseam seal tape 316 layers. In the case ofstitches channel opening 122. - Although only preferred embodiments are specifically illustrated and described herein, it will be appreciated that many modifications and variations of the present invention are possible in light of the above teachings and within the purview of the appended claims without departing from the spirit and intended scope of the invention.
