Definitions
- the present disclosure generally relates to packaging, and particularly to packaging of items having a sticky or tacky surface on at least a portion of a surface of the item.
- packaging plays an important role for manufacturers of products to provide end-users with a quality product. Due to the importance of packaging, a manufacturer may scrutinize each individual item to determine the best and most efficient way to ship the item. Packaging and shipping expenses may be a costly and resource intensive portion of a manufacturer's production process. Any improvements in the packaging characteristics of an item that reduces the number of packages, the size of the package, and/or the time associated with packaging the item may greatly decreases the overall production cost of that particular item. Therefore, reducing packaging and shipping costs may be beneficial to a manufacturer, allowing for either increased profit or a more competitive price of the item in the market.
- the successful packaging of varying types of items may present a varying set of packaging challenges, depending on the characteristics of the items to be packaged.
- the following list represents various item categories and generally illustrates that the characteristics of an item to be packaged may be associated with the characteristics of the packaging of that item.
- Some example item categories may include:
- Non-fragile solids non-fragile solid items may be packaged in a plastic wrap or bag, and then placed in a box with standard cushioning material;
- Fragile solids fragmente solid items may be packaged in a plastic wrap or bag, and then placed in a box with maximum amount of cushioning material;
- Liquids liquids may be packaged in a shatter-resistant container that is covered by a plastic wrap or bag;
- Gases may be packaged in a metal puncture resistant cylinder that is covered in plastic wrap or a bag.
- specialty items that pose a packaging challenge may include substances and/or compounds that are gummy or sticky. Items that are gummy or sticky have an inherent property of adhering to items with which they come into contact. In particular, gummy or sticky items may adhere to conventional packaging or wrappers and, in most cases, make it nearly impossible to separate the item from the packaging. Thus, gummy or sticky items require customized packaging in order to successfully provide the gummy or sticky item to the end user.
- Some convention strategies in packaging gummy or sticky items include:
- No-stick wrapper may be a single component material designed at the molecular level to minimize adhesion between the gummy item and the wrapper.
- suitable no-stick wrapper materials include fluorinated or chlorinated polymers such as Teflon, polymeric silicone or PVC. Other materials could include solid waxes, such as paraffin.
- release agents are compounds that are applied onto the packaging that minimizes adhesion between the gummy or sticky item and the packaging.
- release agents include waxes, such as those found coated onto wax paper.
- Other release agents could include oils, such as silicone or vegetable oils. Traditionally, oils may be applied on a polymeric or paper sheet.
- a FRUIT ROLL-UP utilizes a type of no-stick wrapper.
- a FRUIT ROLL-UP is made of a thin sticky layer of a fruit laden confection that is applied to a sheet of cellophane. After application, the sheet of cellophane is rolled up such that both the front and back of the cellophane act as a continuous wrapper.
- the packaging of the FRUIT ROLL-UP may protect both sides of the sticky fruit laden confection
- this type of packaging has several disadvantages.
- One example drawback is that the ease of separating the confection depends on which side of the cellophane the confection releases first. Ideally the fruit laden confection releases on the leading end of the cellophane causing the roll to unravel and provide access to the FRUIT ROLL-UP. Often times, however, the fruit laden confection will stay stuck to the body of the roll causing the end-user to have to tediously and carefully peel away the confection. Furthermore, during the tedious peeling away process, the FRUIT ROLL-UP will often tear, causing the unpacking process to become increasingly more difficult and frustrating for the end-user.
- FRUIT ROLL-UP type wrapper requires an additional package to environmentally seal the FRUIT ROLL-UP.
- a FRUIT ROLL-UP requires a no-stick wrapper to manage the sticky confection, and requires an additional package to environmentally seal the FRUIT ROLL-UP. Without the use of an additional package, the no-stick wrapper may fail to seal the FRUIT ROLL-UP, causing the FRUIT ROLL-UP to dry out and/or become contaminated.
- An example of using a release agent in the packaging of gummy or sticky items is the packaging of salt-water taffy.
- the conventional wrapper for salt-water taffy is wax paper.
- the wax serves as a releasing agent because the wax is inherently harder to adhere to than paper.
- One disadvantage to using a release agent like wax is that the wax may release onto the candy and be ingested by the end user.
- Another disadvantage to the packaging design of saltwater taffy is that it is not individually environmentally sealed.
- a third example of packaging a gummy or sticky item is dental whitening strips, such as CREST WHITESTRIPS.
- CREST WHITESTRIPS essentially consist of a plastic backing material layered with a coat of whitening gel that has a sticky characteristic.
- a release liner is used to cover the whitening gel.
- the whitening gel is positioned between a backing material and a release liner. The whitening gel is then placed within an additional package to protect the whitening gel from the environment, thus preventing the whitening gel from drying out or becoming contaminated.
- Implementations of the present invention include methods, devices, and systems that provide effective packaging items with at least one gummy surface.
- implementations of the present invention provide a package for items with a gummy surface that does not require a separate liner to be placed on the gummy surface.
- the package includes inadhesive polymers such that the item can be removeably adhered to a portion of the package.

- example embodiments of the present invention allow an end-user to easily open the package. Once opened, the package provides the user with easy access to the item with the gummy surface. Thus, although the item is gummy and sticky, the package allows an end-user to easily access the item for use without necessarily having to interfere with the gummy surface of the item.

- a gummy surface is a surface that includes one or more of the following properties: sticky, gel-like, jelly-like, gluey, and/or includes any adhesive characteristics.
- Package 100 can include a first sheet 102 (e.g. top sheet) and a second sheet 104 (e.g. bottom sheet).
- first sheet 102 e.g. top sheet
- second sheet 104 e.g. bottom sheet
- first sheet 102 is a plastic sheet
- second sheet 104 is a paper sheet.
- both the first sheet 102 and the second sheet 104 may be made from plastic.
- any of the above mentioned materials, or similar materials may be used as the first sheet 102 and the second sheet 104 material.
- the first sheet 102 and the second sheet 104 may include a defined storage area 112 as shown on the second sheet 104 in FIG. 1A (the first sheet has a corresponding defined storage area).
- the defined storage area 112 is the defined area where an item will be stored. Accordingly, the first sheet 102 and the second sheet 104 have substantially the same dimensions and shape. In this manner, the first sheet 102 and the second sheet 104 can be coupled together to form an enclosed space between the first sheet 102 and the second sheet 104 around the defined area 112 .
- treatment strips 106 can be placed in the defined area 112 to be packaged.
- Treatment strips 106 may have various properties and characteristics.
- the treatments strips 106 comprise a gummy surface 108 and backing material 110 .
- the gummy surface 108 is sticky and includes adhesive properties, while the backing material 110 does not easily adhere to other surfaces.
- the treatment strip 106 is not attached to, nor does it include, a separate release liner. Rather, and as will be explained further below, the actual package 100 interfaces with the gummy surface 108 of the treatment strips.
- FIG. 1B illustrates the package 100 assembled such that the treatment strips 106 are enclosed within the enclosed space in the defined area 112 .
- the gummy surface 108 of the treatment strips interfaces with the first sheet 102 such that the treatment strips 106 are held in place during shipping and handling.
- the package 100 can include an outer seam 114 , whereby the first sheet 102 and the second sheet 104 are sealed together, thereby environmentally sealing the treatment strips 106 within the packaging system 100 .
- the outer seam 114 is heat-sealed forming a releasable bond between the first sheet 102 and the second sheet 104 .
- Other methods of sealing the first sheet 102 to the second sheet 104 may also be used (e.g., using a chemical adhesive).
- an end-user can easily open the package 100 and gain access to the treatment strips 106 .
- one or more corners 116 of the package 100 can be left unsealed such that a user can separate the first sheet 102 from the second sheet 104 at the position of the corner 116 .
- a user may peel apart the first sheet 102 from the second sheet 104 , thereby exposing the treatment strips 106 .
- the treatment strips 106 will remain adhered to the first sheet 104 , while the backing material 110 allows the treatment strips 106 to cleanly release from the second sheet 104 .
- a user simply has to peel the treatment strips 106 off the first sheet 102 .
- the gummy surface 108 may have less adhesion to the first sheet 102 than to the backing material, thus allowing the gummy surface 108 to release from the first sheet 102 before releasing from the backing material 110 .
- the treatment strip 106 can include two gummy surfaces (e.g., not include backing material 110 ) such that the treatment strip adheres to both the first sheet 102 and the second sheet 104 .
- the first sheet 102 and the second sheet 104 may be made from the same or similar material (e.g., a plastic). Even though both the first sheet 102 and the second sheet 104 are made of the same material and have the same adhesive affinity to the gummy surface 108 , it is still possible to separate just one of the sheets.
- the end-user when attempting to remove the treatment strip 106 having two gummy surfaces 108 from polyethylene sheets (e.g., the first sheet 102 and the second sheet 104 ), the end-user will usually grab one end of the polyethylene sheet and hold it stationary while applying the peeling force to the other sheet. It is most often the polyethylene sheet receiving the peeling force that peels first, while leaving the other polyethylene sheet intact. In a few cases the polyethylene sheet will begin to peel from the stationary side, in which case the end result will be the same. There are also slight differences introduced in manufacturing that can determine which side of the polyethylene sheet peels first, such as a void or overhang of gummy material that favors or disfavors one side over another. Such nuances could be intentionally designed into the gummy surface, or gel layer if so desired. This embodiment may be incorporated for all packages, and packaging systems described throughout this specification.
- FIG. 2A illustrates another example embodiment of a package 200 .
- package 200 may be used to package treatment strip 206 .
- treatment strip 206 is not attached to, or does not include, a separate release liner. Rather, it is the material of the package 200 that directly interfaces with the treatment strip 206 . Therefore, in one implementation, the treatment strip 206 can have a backing material on one side of the treatment strip 206 , or alternatively, the treatment strip 206 may not include any backing layer such that each surface of the treatment strip 206 is a gummy surface.

- the package 200 may include weakened seams 208 running lengthwise along the edges of the package 200 .
- the treatment strip 206 is positioned on the second sheet 204 of the package 200 and is removably adhered thereto by the adhesive nature of the gummy surface on the treatment strip 206 .

Description
- This application claims the benefit of U.S. Provisional Application No. 61/276,993, filed Sep. 18, 2009, and U.S. Provisional Application No. 61/319,124, filed Mar. 30, 2010. Both the '993 and the '124 applications are incorporated herein by reference in their entirety.
- The present disclosure generally relates to packaging, and particularly to packaging of items having a sticky or tacky surface on at least a portion of a surface of the item.
- Many items and products that are manufactured today are packaged for shipment to various commercial destinations. In fact, most products sold in today's economy are at one time or another packaged during the various stages of manufacturing, handling or shipping. Although there are various reasons for packaging a product (e.g., customer recognition or marketing) a primary purpose of a package is to protect the contents of the package during the handling and shipping process until the package is eventually opened by the end-user. Therefore, manufacturers often design packages to allow a particular product to arrive to the end-user in essentially the same condition as the product left the manufacturer.
- Accordingly, packaging plays an important role for manufacturers of products to provide end-users with a quality product. Due to the importance of packaging, a manufacturer may scrutinize each individual item to determine the best and most efficient way to ship the item. Packaging and shipping expenses may be a costly and resource intensive portion of a manufacturer's production process. Any improvements in the packaging characteristics of an item that reduces the number of packages, the size of the package, and/or the time associated with packaging the item may greatly decreases the overall production cost of that particular item. Therefore, reducing packaging and shipping costs may be beneficial to a manufacturer, allowing for either increased profit or a more competitive price of the item in the market.
- The successful packaging of varying types of items may present a varying set of packaging challenges, depending on the characteristics of the items to be packaged. For example, the following list represents various item categories and generally illustrates that the characteristics of an item to be packaged may be associated with the characteristics of the packaging of that item. Some example item categories may include:
- 1. Non-fragile solids—non-fragile solid items may be packaged in a plastic wrap or bag, and then placed in a box with standard cushioning material;
- 2. Fragile solids—fragile solid items may be packaged in a plastic wrap or bag, and then placed in a box with maximum amount of cushioning material;
- 3. Liquids—liquids may be packaged in a shatter-resistant container that is covered by a plastic wrap or bag; and
- 4. Gases—gases may be packaged in a metal puncture resistant cylinder that is covered in plastic wrap or a bag.
- Notwithstanding the above general categories, some specialty items are much more difficult to package and ship, which often leads to customized packaging to allow adequate delivery of the specialty items to the end-user.
- One example of specialty items that pose a packaging challenge may include substances and/or compounds that are gummy or sticky. Items that are gummy or sticky have an inherent property of adhering to items with which they come into contact. In particular, gummy or sticky items may adhere to conventional packaging or wrappers and, in most cases, make it nearly impossible to separate the item from the packaging. Thus, gummy or sticky items require customized packaging in order to successfully provide the gummy or sticky item to the end user.
- Various strategies have been developed to manage the problems associated with packaging gummy or sticky items. Some convention strategies in packaging gummy or sticky items include:
- 1. No-stick wrapper—A no-stick wrapper may be a single component material designed at the molecular level to minimize adhesion between the gummy item and the wrapper. Examples of suitable no-stick wrapper materials include fluorinated or chlorinated polymers such as Teflon, polymeric silicone or PVC. Other materials could include solid waxes, such as paraffin.
- 2. Release Agents—Conventionally, release agents are compounds that are applied onto the packaging that minimizes adhesion between the gummy or sticky item and the packaging. Examples of release agents include waxes, such as those found coated onto wax paper. Other release agents could include oils, such as silicone or vegetable oils. Traditionally, oils may be applied on a polymeric or paper sheet.
- Currently, there are various gummy or sticky items that are commercially available that utilize the various packaging techniques to package a gummy or sticky item. For example, a FRUIT ROLL-UP utilizes a type of no-stick wrapper. In particular, a FRUIT ROLL-UP is made of a thin sticky layer of a fruit laden confection that is applied to a sheet of cellophane. After application, the sheet of cellophane is rolled up such that both the front and back of the cellophane act as a continuous wrapper.
- Although the packaging of the FRUIT ROLL-UP may protect both sides of the sticky fruit laden confection, this type of packaging has several disadvantages. One example drawback is that the ease of separating the confection depends on which side of the cellophane the confection releases first. Ideally the fruit laden confection releases on the leading end of the cellophane causing the roll to unravel and provide access to the FRUIT ROLL-UP. Often times, however, the fruit laden confection will stay stuck to the body of the roll causing the end-user to have to tediously and carefully peel away the confection. Furthermore, during the tedious peeling away process, the FRUIT ROLL-UP will often tear, causing the unpacking process to become increasingly more difficult and frustrating for the end-user.
- Another disadvantage of a FRUIT ROLL-UP type wrapper is that it requires an additional package to environmentally seal the FRUIT ROLL-UP. In particular, a FRUIT ROLL-UP requires a no-stick wrapper to manage the sticky confection, and requires an additional package to environmentally seal the FRUIT ROLL-UP. Without the use of an additional package, the no-stick wrapper may fail to seal the FRUIT ROLL-UP, causing the FRUIT ROLL-UP to dry out and/or become contaminated.
- An example of using a release agent in the packaging of gummy or sticky items is the packaging of salt-water taffy. The conventional wrapper for salt-water taffy is wax paper. The wax serves as a releasing agent because the wax is inherently harder to adhere to than paper. One disadvantage to using a release agent like wax is that the wax may release onto the candy and be ingested by the end user. Another disadvantage to the packaging design of saltwater taffy is that it is not individually environmentally sealed.
- A third example of packaging a gummy or sticky item is dental whitening strips, such as CREST WHITESTRIPS. CREST WHITESTRIPS essentially consist of a plastic backing material layered with a coat of whitening gel that has a sticky characteristic. In order to protect the whitening gel, a release liner is used to cover the whitening gel. Thus, the whitening gel is positioned between a backing material and a release liner. The whitening gel is then placed within an additional package to protect the whitening gel from the environment, thus preventing the whitening gel from drying out or becoming contaminated.
- One disadvantage to conventional packaging for whitening gels, as described above, is that if whitening gel is packaged without a release liner, then the whitening gel causes a mess and will not arrive to the end-user in a useable form. On the other hand, by using a release liner, an additional manufacturing step, as well as additional packaging material, is added to the packaging of the whitening gel, causing the cost to package and ship the whitening gel to increase. Moreover, a release liner does not seal out the sides of the whitening gel, and therefore a second environment package must be used, again causing the cost of packaging and shipping to increase.
- Accordingly, there are a number of disadvantages in the conventional art of packaging gummy or sticky substances.
- Implementations of the present invention include methods, devices, and systems that provide effective packaging items with at least one gummy surface. In particular, implementations of the present invention provide a package for items with a gummy surface that does not require a separate liner to be placed on the gummy surface. In example implementations, the package includes inadhesive polymers such that the item can be removeably adhered to a portion of the package.
- Additional features and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by the practice of the invention. The features and advantages of the invention may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims. These and other features of the present invention will become more fully apparent from the following description and appended claims, or may be learned by the practice of the invention as set forth hereinafter.
- In order to describe the manner in which the above-recited and other advantages and features of the invention can be obtained, a more particular description of the invention briefly described above will be rendered by reference to specific example implementations thereof which are illustrated in the appended drawings. Understanding that these drawings depict only typical implementations of the invention and are not therefore to be considered to be limiting of its scope, the invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
-
FIG. 1A illustrates an exploded view of a package according to principles described herein; -
FIG. 1B illustrates an assembled view of the package ofFIG. 1A ; -
FIG. 2A illustrates another example embodiment of a package according to principles described herein; -
FIG. 2B illustrates an elevated side view of the package ofFIG. 2A ; -
FIG. 2C illustrates a user beginning to open the package ofFIG. 2A ; -
FIG. 2D illustrate a user at a mid-point of opening the package ofFIG. 2A ; -
FIG. 2E illustrates a user accessing the gummy item after opening the package ofFIG. 2A ; and -
FIG. 3 illustrates an example method of packaging a gummy item according to principles described herein. - Implementations of the present invention include methods, devices, and systems that provide effective packaging items with at least one gummy surface. In particular, implementations of the present invention provide a package for items with a gummy surface that does not require a separate liner to be placed on the gummy surface. In example implementations, the package includes inadhesive polymers such that the item can be removeably adhered to a portion of the package.
- As will be appreciated more fully herein, implementations of the present invention provide an effective package for items having at least one gummy surface. In particular, example embodiments of the invention provide an environmentally sealed package that does not allow the gummy surface of the item to dry out. Moreover, due to the sealed package, the item is protected from any contamination outside the package.
- Additionally, example embodiments of the present invention allow an end-user to easily open the package. Once opened, the package provides the user with easy access to the item with the gummy surface. Thus, although the item is gummy and sticky, the package allows an end-user to easily access the item for use without necessarily having to interfere with the gummy surface of the item.
- Also, example embodiments of the present invention provide a cost effective and time efficient method of packaging items having at least one gummy surface. For example, the item with the gummy surface may be placed within the package without having a release liner, or similar device. Thus, the present invention provides a package that requires less material and less time to package, which in turn reduces expenses.
- As an overview, the packaging of the present invention may use a variety of polymers and materials that are substantially nonadhesive by nature. Materials such as fluoro-polymers, chloro-polymers, silicone-polymers, and long chained alkane type polymers are preferred. Polymers such as PTFE, polyethylene, polypropylene, PFA, FEP, ETFE, PVDF, ETFE, ECTFE, PCTFE, FFKM, PFPE, polysiloxanes and any like polymers are further within the scope of this invention. Preferred polymers are also chosen among the group that is most amenable to blow, vacuum or injection molding such that the manufacturing of the package is most efficient.
- In addition the various materials with which the packaging can be made, the packaging can be configured to have any geometric dimension and configuration. As will be discussed further below, exemplary embodiments of the invention are directed toward packaging one or more treatment strips (e.g., dental treatment strips). Accordingly, the packaging described and illustrated below includes a substantially flat rectangular geometric configuration having dimensions that correspond to the relative dimensions of the dental treatment strips. However, the invention is not limited to these geometric configurations as the packaging can include almost any geometric configuration necessary for a particular item to be packaged.
- Moreover, example embodiments of the present invention are not limited to packaging treatment strips. Rather, example embodiments of the present invention may be used to package almost any item that includes at least one gummy surface. For the purposes of this application, a gummy surface is a surface that includes one or more of the following properties: sticky, gel-like, jelly-like, gluey, and/or includes any adhesive characteristics.
- Referring now to
FIG. 1A , an exploded view of anexample package 100 is shown.Package 100 can include a first sheet 102 (e.g. top sheet) and a second sheet 104 (e.g. bottom sheet). In one example embodiment, thefirst sheet 102 is a plastic sheet andsecond sheet 104 is a paper sheet. In alternative implementations, both thefirst sheet 102 and thesecond sheet 104 may be made from plastic. Moreover, any of the above mentioned materials, or similar materials, may be used as thefirst sheet 102 and thesecond sheet 104 material. - Notwithstanding their material, the
first sheet 102 and thesecond sheet 104 may include a definedstorage area 112 as shown on thesecond sheet 104 inFIG. 1A (the first sheet has a corresponding defined storage area). The definedstorage area 112 is the defined area where an item will be stored. Accordingly, thefirst sheet 102 and thesecond sheet 104 have substantially the same dimensions and shape. In this manner, thefirst sheet 102 and thesecond sheet 104 can be coupled together to form an enclosed space between thefirst sheet 102 and thesecond sheet 104 around the definedarea 112. - For example, and as illustrated in
FIG. 1A , treatment strips 106 can be placed in the definedarea 112 to be packaged. Treatment strips 106 may have various properties and characteristics. In one embodiment, the treatments strips 106 comprise agummy surface 108 andbacking material 110. Thegummy surface 108 is sticky and includes adhesive properties, while thebacking material 110 does not easily adhere to other surfaces. It is noteworthy that thetreatment strip 106 is not attached to, nor does it include, a separate release liner. Rather, and as will be explained further below, theactual package 100 interfaces with thegummy surface 108 of the treatment strips. - In order to package the treatment strips 106, the
gummy surface 108 of thetreatment strip 106 is placed against thefirst sheet 102, while thebacking material 110 of the treatment strips 106 are placed against thesecond sheet 104 of thepackage 100. For example,FIG. 1B illustrates thepackage 100 assembled such that the treatment strips 106 are enclosed within the enclosed space in the definedarea 112. As illustrated inFIG. 1B , thegummy surface 108 of the treatment strips interfaces with thefirst sheet 102 such that the treatment strips 106 are held in place during shipping and handling. - In order to further secure the treatment strips 106 within the
package 100, thepackage 100 can include anouter seam 114, whereby thefirst sheet 102 and thesecond sheet 104 are sealed together, thereby environmentally sealing the treatment strips 106 within thepackaging system 100. In one embodiment, theouter seam 114 is heat-sealed forming a releasable bond between thefirst sheet 102 and thesecond sheet 104. Other methods of sealing thefirst sheet 102 to thesecond sheet 104 may also be used (e.g., using a chemical adhesive). - Once the treatment strips 106 are packaged within the
package 100, an end-user can easily open thepackage 100 and gain access to the treatment strips 106. For example, and as illustrated inFIG. 1B , one ormore corners 116 of thepackage 100 can be left unsealed such that a user can separate thefirst sheet 102 from thesecond sheet 104 at the position of thecorner 116. Upon separating thefirst sheet 102 from thesecond sheet 104 at thecorner 116, a user may peel apart thefirst sheet 102 from thesecond sheet 104, thereby exposing the treatment strips 106. - Once the
first sheet 102 and thesecond sheet 104 are separated, the treatment strips 106 will remain adhered to thefirst sheet 104, while thebacking material 110 allows the treatment strips 106 to cleanly release from thesecond sheet 104. At this point, a user simply has to peel the treatment strips 106 off thefirst sheet 102. For example, thegummy surface 108 may have less adhesion to thefirst sheet 102 than to the backing material, thus allowing thegummy surface 108 to release from thefirst sheet 102 before releasing from thebacking material 110. - In an alternative embodiment, the
treatment strip 106 can include two gummy surfaces (e.g., not include backing material 110) such that the treatment strip adheres to both thefirst sheet 102 and thesecond sheet 104. In this embodiment, thefirst sheet 102 and thesecond sheet 104 may be made from the same or similar material (e.g., a plastic). Even though both thefirst sheet 102 and thesecond sheet 104 are made of the same material and have the same adhesive affinity to thegummy surface 108, it is still possible to separate just one of the sheets. - For example, when attempting to remove the
treatment strip 106 having twogummy surfaces 108 from polyethylene sheets (e.g., thefirst sheet 102 and the second sheet 104), the end-user will usually grab one end of the polyethylene sheet and hold it stationary while applying the peeling force to the other sheet. It is most often the polyethylene sheet receiving the peeling force that peels first, while leaving the other polyethylene sheet intact. In a few cases the polyethylene sheet will begin to peel from the stationary side, in which case the end result will be the same. There are also slight differences introduced in manufacturing that can determine which side of the polyethylene sheet peels first, such as a void or overhang of gummy material that favors or disfavors one side over another. Such nuances could be intentionally designed into the gummy surface, or gel layer if so desired. This embodiment may be incorporated for all packages, and packaging systems described throughout this specification. - In a similar manner,
FIG. 2A illustrates another example embodiment of apackage 200. Similar to the above discussion with reference toFIGS. 1A-1B ,package 200 may be used to packagetreatment strip 206. As above, it is noteworthy thattreatment strip 206 is not attached to, or does not include, a separate release liner. Rather, it is the material of thepackage 200 that directly interfaces with thetreatment strip 206. Therefore, in one implementation, thetreatment strip 206 can have a backing material on one side of thetreatment strip 206, or alternatively, thetreatment strip 206 may not include any backing layer such that each surface of thetreatment strip 206 is a gummy surface. - Referring back to
FIG. 2 ,packaging 200 includes a plastic bag configuration having a first sheet 202 (e.g., top sheet) and a second sheet (e.g., bottom sheet). Thefirst sheet 102 and thesecond sheet 104 may include a zip-lock opening 210 that can be sealed. Moreover, thepackage 200 may include weakenedseams 208 running lengthwise along the edges of thepackage 200. - In one embodiment, the
treatment strip 206 is positioned on thesecond sheet 204 of thepackage 200 and is removably adhered thereto by the adhesive nature of the gummy surface on thetreatment strip 206. The backing material on the opposing side of thetreatment strip 206 has little or no adhesion to thefirst sheet 202 since the only contact between thefirst sheet 202 and thetreatment strip 206 is with the backing material of thetreatment strip 206. -
FIGS. 2B through 2E illustrate one way in which an end-user can open thepackage 200 to gain access to thetreatment strip 206. For example,FIG. 2B illustrates a side view of thepackage 200.FIG. 2B shows that acorner 212 of thefirst sheet 202 near the zip-lock opening 210 may be peeled away from thesecond sheet 204. - As illustrated in
FIG. 2C , an end-user may start to open thepackage 200 by grasping thecorner 212 and pulling apart the zip-lock opening 210. Upon opening the zip-lock opening 210, the end-user can continue to pull thefirst sheet 202 away from thesecond sheet 204 by breaking the weakenedseams 208 between thefirst sheet 202 and thesecond sheet 204, as illustrated inFIG. 2D . Once thefirst sheet 102 is sufficiently separated from thesecond sheet 202, the end-user may then grasp thetreatment strip 206 and peel thetreatment strip 206 off of thesecond sheet 204, as illustrated inFIG. 2E . - In an alternative embodiment,
package 200 may include a zip-lock or zipper mechanism on more than one side of the bag. The invention contemplates the use of a zip-lock or zipper that opens one, two, three or four sides of thepackage 200. - Accordingly,
FIGS. 1A through 2E and the corresponding text provide a number of different components and modules that provide a package used to package an item with at least one gummy surface. In addition to the foregoing, implementations of the present invention can also be described in terms of flowcharts comprising one or more acts in a method for accomplishing a particular result. For example,FIG. 3 illustrates amethod 300 of packaging an item with at least one gummy surface. The acts ofFIG. 3 are discussed more fully below with respect to the components discussed with reference toFIG. 1A throughFIG. 2E . - For example,
FIG. 3 shows that themethod 300 comprises anact 302 of adhering a gummy surface of an item directly to a first sheet. For example,FIG. 1B shows that thetreatment strip 106 can include agummy surface 108 that adheres to afirst sheet 102. - Also, the
method 300 comprises anact 304 of sealing the item between the first sheet and a second sheet. For example,FIGS. 1A and 1B illustrate that treatment strips 106 may be sealed betweenfirst sheet 102 andsecond sheet 104. - Accordingly, the diagrams and figures provided in
FIG. 1 throughFIG. 3 illustrate a number of methods, devices, systems, configurations, and components that can be used to effectively package an item having a gummy surface. - The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described implementations are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
