Definitions

  • This invention relates to a fluid applicator whereby fluids, such as skin-preparation liquids, may be controllably applied to a surface. More particularly, this inventbn relates to an applicator which is capable of single-finger activation.
  • These applicators typically include a container for containment of the fluid, a means to activate the fluid applicator, and means to transfer the fluid from the fluid applicator to the surface.
  • the prior art fluid applicators contain the fluid until the time of application.
  • These fluid activators may employ a seal that prevents the fluid from moving out of the container.
  • the prior art fluid activators may also include means to break the seal, thus allowing the fluid to leave the container.
  • These prior art fluid applicators typically include means for applying the fluid to a surface.
  • One such prior art fluid applicator includes a tubular handle, a cartridge, and a sponge.
  • the tubular handle includes a hollow spike.
  • This device is designed for two-handed activation.
  • activation refers to the process by which a fluid applicator is made ready to apply a fluid, such as by breaking an ampoule.
  • operation refers to the process by which the fluid applicator is used to apply a fluid to a surface.
  • the cartridge contains the fluid to be applied and is made from a material which can be ruptured by the spike.
  • the tubular handle has an inside diameter which is sized to accept the cartridge. In activation, with one hand holding the tubular handle, the other hand pushes the cartridge onto the spike thus rupturing the cartridge.
  • the sponge is attached to one end of the tubular handle and is in fluid communication with the hollow spike. When the cartridge is ruptured, fluid may flow from the cartridge through the spike and into the sponge. The sponge may ad applying the fluid to a surface.
  • One prior art fluid applicator includes a tubular handle and a glass cartridge.
  • the tubular handle includes a sponge disposed at one end.
  • the tubular handle includes an end cap that slidably fits the exterior of the tubular handle.
  • the tubular cartridge further includes a shoulder which constrains the glass cartridge.
  • the end cap is struck so that it moves with respect to the tubular handle and pushes the cartridge down into the handle.
  • the glass cartridge being constrained by the shoulder fractures thus releasing fluid. The fluid may then flow into the sponge.
  • this fluid applicator also requires two-handed activation.
  • Still another prior art fluid applicator includes an applicator head assembly and a fluid container. Fluid is contained in the fluid container by a rupturable seal.
  • the applicator head assembly is threadably connected to the fluid container.
  • the applicator head assembly includes a hollow spike which can be in fluid communication with a sponge disposed on the end of the applicator head assembly.
  • the applicator head assembly also includes an outer component and an inner component. The hollow spike is disposed in the inner component.
  • the outer component can be held in a fixed position with respect to the fluid container by a breakable locking mechanism. To activate this device, the outer component is rapidly moved downward thus breaking the breakable locking mechanism and pushing the hollow spike through the seal into the fluid container. In this way fluid may flow into the sponge. Because of the breakable locking mechanism, the activation of this device generally requires the use of two hands.
  • Each of these prior art devices has certain disadvantages. Some of these prior art devices include multiple loose components which slidabK mate with each other and therefore may easily become separated. Some of these prior art devices include glass cartridges which may fracture at inappropriate times because they are made of glass. Each of these prior art devices requires the use of two hands to activate which is not desirable in certain applications such as those arising in a hospital operating room.
  • What would therefore be advantageous would be a fluid applicator which does not include multiple loose components which slidably mate with each other. It would be a further advantage to have a fluid applicator which did not rely on the use of glass cartridges. It would still be a further advantage to have a fluid applicator which allowed single-finger or single-thumb activation and single-handed operation.
  • Summary of the Invention The present invention provides a fluid applicator which allows single-finger or single- thumb activation and single-handed operation.
  • the present invention provides a fluid applicator with only one moving part.
  • the present invention provides a fluid applicator which does not rely on a glass cartridge.
  • the present invention also provides a unitary device which does not employ the slidable components of the prior art devices.
  • the present invention provides a fluid applicator comprising: a fluid container: a header further defining a skirt and a tubular pathway, the header connected to the fluid container: a sleeve connected to the header: and a hollow penetrator further defining a fluid path that provides fluid communication between the fluid container and the tubular pathway, the hollow penetrator slidably disposed in the sleeve.
  • the present invention further provides flow control of a fluid delivered from the fluid applicator and a locking device that prevents accidental activation of the fluid applicator. Description of the Drawings

Description

A SINGLE-FINGER ACTIVATED SINGLE-HAND OPERATED FLUID
APPLICATOR
Field of the Invention
This invention relates to a fluid applicator whereby fluids, such as skin-preparation liquids, may be controllably applied to a surface. More particularly, this inventbn relates to an applicator which is capable of single-finger activation.
Background of the Invention
The use of fluid applicators for applying a fluid to a surface is known in the art.
These applicators typically include a container for containment of the fluid, a means to activate the fluid applicator, and means to transfer the fluid from the fluid applicator to the surface. Generally, the prior art fluid applicators contain the fluid until the time of application. These fluid activators may employ a seal that prevents the fluid from moving out of the container. The prior art fluid activators may also include means to break the seal, thus allowing the fluid to leave the container. These prior art fluid applicators typically include means for applying the fluid to a surface.
One such prior art fluid applicator includes a tubular handle, a cartridge, and a sponge. The tubular handle includes a hollow spike. This device is designed for two-handed activation. The term activation refers to the process by which a fluid applicator is made ready to apply a fluid, such as by breaking an ampoule. The term operation refers to the process by which the fluid applicator is used to apply a fluid to a surface. The cartridge contains the fluid to be applied and is made from a material which can be ruptured by the spike. The tubular handle has an inside diameter which is sized to accept the cartridge. In activation, with one hand holding the tubular handle, the other hand pushes the cartridge onto the spike thus rupturing the cartridge. The sponge is attached to one end of the tubular handle and is in fluid communication with the hollow spike. When the cartridge is ruptured, fluid may flow from the cartridge through the spike and into the sponge. The sponge may ad applying the fluid to a surface.
One prior art fluid applicator includes a tubular handle and a glass cartridge. The tubular handle includes a sponge disposed at one end. The tubular handle includes an end cap that slidably fits the exterior of the tubular handle. The tubular cartridge further includes a shoulder which constrains the glass cartridge. To activate this prior art device, the end cap is struck so that it moves with respect to the tubular handle and pushes the cartridge down into the handle. The glass cartridge being constrained by the shoulder fractures thus releasing fluid. The fluid may then flow into the sponge. Thus, it can be seen that this fluid applicator also requires two-handed activation.
Still another prior art fluid applicator includes an applicator head assembly and a fluid container. Fluid is contained in the fluid container by a rupturable seal. The applicator head assembly is threadably connected to the fluid container. The applicator head assembly includes a hollow spike which can be in fluid communication with a sponge disposed on the end of the applicator head assembly. The applicator head assembly also includes an outer component and an inner component. The hollow spike is disposed in the inner component. The outer component can be held in a fixed position with respect to the fluid container by a breakable locking mechanism. To activate this device, the outer component is rapidly moved downward thus breaking the breakable locking mechanism and pushing the hollow spike through the seal into the fluid container. In this way fluid may flow into the sponge. Because of the breakable locking mechanism, the activation of this device generally requires the use of two hands.
Each of these prior art devices has certain disadvantages. Some of these prior art devices include multiple loose components which slidabK mate with each other and therefore may easily become separated. Some of these prior art devices include glass cartridges which may fracture at inappropriate times because they are made of glass. Each of these prior art devices requires the use of two hands to activate which is not desirable in certain applications such as those arising in a hospital operating room.
What would therefore be advantageous would be a fluid applicator which does not include multiple loose components which slidably mate with each other. It would be a further advantage to have a fluid applicator which did not rely on the use of glass cartridges. It would still be a further advantage to have a fluid applicator which allowed single-finger or single-thumb activation and single-handed operation. Summary of the Invention The present invention provides a fluid applicator which allows single-finger or single- thumb activation and single-handed operation. The present invention provides a fluid applicator with only one moving part. The present invention provides a fluid applicator which does not rely on a glass cartridge. The present invention also provides a unitary device which does not employ the slidable components of the prior art devices. The present invention provides a fluid applicator comprising: a fluid container: a header further defining a skirt and a tubular pathway, the header connected to the fluid container: a sleeve connected to the header: and a hollow penetrator further defining a fluid path that provides fluid communication between the fluid container and the tubular pathway, the hollow penetrator slidably disposed in the sleeve. The present invention further provides flow control of a fluid delivered from the fluid applicator and a locking device that prevents accidental activation of the fluid applicator.

Referring to figure 1. a fluid applicator made in accordance with the principles of the present invention is designated by 10. The fluid applicator 10 includes a fluid container 13, a header 19 and a spike 20 disposed in the header 19. The fluid container 13 includes a top opening 18 as is typically found in a bottle, for example. The header may include a skirt 14, a tubular pathway 12 and a foam pad 16. A flow control device may 15 be positioned in the tubular pathway 12 at a location that lies between the foam pad 16 and the fluid container 13. The fluid container 13 includes a seal 1 7. The seal 17 is preferably an induction seal, as further described below. The seal 17 can be disposed between a shoulder 1 1 and the fluid container 13. The shoulder 1 1 serves to contain the seal 17 against the top opening 18 of the fluid container 13.
The induction seal 17 is typically a rupturable seal that is secured to the opening 18 of the fluid container 13. When the seal 17 is intact, the fluid applicator 10 is said to be in the inactivated position. When the seal 17 has been ruptured, the fluid applicator 10 is said to be in the activated position. The induction seal 17 may be secured to the opening 18 by application of an adhesive, by heat-sealing, by a combination of these two methods, by ultrasonication or other methods. The induction seal 17 may be manufactured from a thin foil, a thin plastic material, or the induction seal 17 may be a composite of these two types of materials. One example of an induction seal is manufactured by 3M Corporation. Minneapolis Minnesota and sold by Unipac. Aurora, and Ontario. Canada.
The spike 20. further illustrated in figure 2. includes a top 25 a fluid communication conduit 24. a fluid outlet 26. and a seal penetrator end 23. The fluid communication conduit 24 allows fluid to enter the spike 20. Fluid may exit the spike 20 through the fluid outlet 26. The seal penetrator end 23 is designed to allow the spike to pierce the seal 17. Preferably, the seal penetrator end 23 includes an inclined cross-sectional geometry distal to the top 25. as depicted in figure 2. However, any geometry that would allow the spike 20 to pierce the seal 17 may be used. Such geometries include an inclined concave surface, an inclined convex surface, a conical surface, an oblate surface, or a planar surface. The seal penetrator end 23 may have a sharpened surface to further facilitate piercing the seal 17.
The spike 20 can be disposed in the header 19. The position of the spike 20 relative to the seal 17 is also shown in figure 3. The spike 20 is preferably positioned vertically above the seal 17 so that the seal penetrator end 23 has access to the seal 17 as further described below. The spike 20 positioned as depicted in figure 3 is said to be in an inactivated position. The header 1 includes a spike retainer 35. The spike retainer 35 is a conduit through which the spike 20 may be moved. The spike retainer 35 further defines a top edge 33. The spike retainer 35 may further define at least one, but preferably two, edge lock receiver 34. The spike 20 may define at least one, but preferably tw o. edge lock 32. Figure 4 illustrates the spike 20 in the position it may assume after the seal 17 has been pierced by the seal penetrator end 23 of the spike 20. The spike 20 positioned as depicted in figure 4 is said to be in an activated position. Upon depression of the spike 20. the seal 17 is broken and the spike 20 is now partially disposed below the fluid container 13 side of the plane of the seal 17. The edge lock 32 is engaged in the edge lock receiver 34 of the spike retainer 35. The top 25 of the spike 20 may contact the top edge 33, thus limiting the extent of travel of the spike 20. Therefore, as illustrated in figure 4. the spatial relationship of the top 25 and the edge lock 32 of the spike 20 is such that when the top 25 contacts the top edge 33 the edge lock 32 is engaged in the edge lock receiver 34.
The header 19 is connected to the fluid container 13. The header 19 includes threads 46 and the fluid container 13 includes threads 48. As shown, the header 19 may be threadably attached to the fluid container 13 when the threads 46 of the header 19engage the threads 48 of the fluid container 13. Alternately, the header 19 may include a lip in the place of threads 46. such that the lip provides a snap-fit connection to the threads 48 of the fluid container 13. The spike 20 slidably fits the interior of the spike retainer 35. The fit between the spike 20 and the interior of the spike retainer 35 is an interference fit such that the spike 20 is not readily pulled out of the spike retainer 35. In an alternate embodiment, the spike 20 further defines a retention edge 37. In the event that an attempt is made to pull the spike 20 out of the spike retainer 35, the retention edge 37 engages the edge lock receiver 34 thus preventing the removal of the spike 20 from the spike retainer 35.
The components of the fluid applicator 10 are constructed from materials known in the art. Preferably, the components are constructed from plastic materials. The components may be made from different plastic materials, although it is possible that the components would be made from the same plastic material. Different components have different desirable attributes which may be more readily attained through the use of different plastic materials. The plastic materials include poly carbonate, polystyrene, polymethylmethacrylate. polymethacrylate butadiene styrene. chlorinated polyvinylchloride. polyvinylidene chloride, and polyvinylidene fluoride, low density pol\ ethylene, polybutylene. and high density polyethylene. It is desirable for the spike retainer 35 to be made from amaterial having a sufficiently low modulus of elasticity so that the spike retainer 35 may deform slightly to accept the insertion of a spike 20 which has a retention edge 37 disposed thereon. However, the modulus of the material cannot be so low as to render the spike retainer 35 rubbery. It is preferred that the header 19 be of a unitary construction. It is desirable that the fluid container 13 be deformable so that pressure may be applied to the fluid container 13 by deforming the fluid container 13 manually so that fluid may be forced to flow into the foam pad 16. The materials of construction are also selected to be compatible with the fluid contained in the fluid container 13 and with the end-use of the fluid applicator 10, as is well understood in the art.
The utility of one embodiment of the fluid applicator 10 of the present invention may be understood upon examination of figures 1 through 4. Prior to use. the fluid applicator 10 contains fluid in the fluid container 13 and has the spike 20 in the position illustrated in figure 3. The seal 17 is unbroken at this point. In such a state, the fluid applicator 10 may be handled, stored, and transported without loss of fluid from the fluid container 13. The edge lock 32 is disposed above the top edge 33 of the spike retainer 35. The edge lock 32 extends beyond the inside diameter of the spike retainer 35. Therefore, for the spike 20 to move downward towards the seal 17 the interference between the edge lock 32 and the top edge 33 of the spike retainer 35 must be overcome. Thus, the fluid applicator 10 of the present invention includes means to prevent an unintended breaking of the seal 17.
When it is desired that fluid contained in the fluid container 13 be dispensed, the spike 20 is depressed into the position it occupies in the illustration of figure 4. The spike 20 may be depressed by grasping the fluid container 13 in one hand and pressing down on the top 25 of the spike 20 using the thumb or a finger of the same hand. By pressing down on the spike 20 the top 25 contacts the top edge 33. the edge lock 32 engages the edge lock receiver 34, and the seal penetrator end 23 breaks the seal 17. The spike 20 is retained in the described position by the engagement of the edge lock 32 and the edge lock receiver 34. With the spike 20 in the described position, fluid may flow from the fluid container 13 into the fluid communication conduit 24. through the fluid outlet 26. into the tubular pathway 12, and into the foam pad 16.
The fluid applicator 10 preferably includes a flow control device 15. The flow control device 15 is preferably a fiber pad. such as a non-woven spun fiber filter. The flow control device may also include any of the known flow control devices, such as an orifice, a slot, a distributor, or other devices known in the art. The purpose of the flow control device 15 is to control the flow of fluid into the foam pad 16. Particularly, where the fluid applicator 10 is being used to apply a surgical skin preparation, control of the flow of the fluid is desirable. Lack of control over the flow of the fluid can result in too little or too much fluid being dispensed to the surface to which the fluid is being applied. One aspect of the flow control device 15 is that it allows the back flow of air into the fluid container 13. The back flow of air allows the fluid container 13 to re-expand after being deformed, such deformation having been described above. An alternate embodiment of the fluid applicator 10 of the present invention is illustrated in figures 5 through 7. The spike 20 has been replaced with a pivotal valve 50. The pivotal valve 50 further defines a locking lip 52. The header 19 further defines a fluid communication path 57 and a retention lip 54. The fluid applicator 10 further includes a fluid container 13. a tubular pathway 12. preferably a flow control device 15. and preferably the fluid container 13 includes threads 46 and the header 1 includes threads 48. The header 19 is connected to the fluid container 13 and. preferably, the header 19 and the fluid container 13 are threadably connected. The fluid container 13 further includes seal 17.
Referring to figure 6. the pivotal valve 50 further defines a top element 58, a pivot element 51. a bottom element 59. and an opening 56 in bottom element 59. Pivot element 51 is a hinge such that pivotal valve 50 may rotate about pivot element 51. Pivot element 51 may be a hinge of any suitable design known in the art.
Prior to use. the fluid applicator 10 contains fluid in the fluid container 13 and has the pivotal valve 50 in the position illustrated in figure 5. The seal 17 is unbroken at this point. In such a state, the fluid applicator 10 may be handled, stored, and transported without loss of fluid from the fluid container 13. The retention lip 54 and the bottom element 59 may be frictionally engaged to form an interference fit. Therefore, for the pivotal valve 50 to move downward towards the seal 17 the interference between the retention lip 54 and the bottom element 59 must be overcome. Thus, the fluid applicator 10 of this embodiment includes means to prevent an unintended breaking of the seal 17.
When it is desired that fluid contained in the fluid container 13 be dispensed, the pivotal valve 50 is depressed to rotate about the pivot element 51 into the position it occupies in the illustration of figure 7. The pivotal valve 50 may be depressed by grasping the fluid container 13 in one hand and pressing down on the top element 58 of the pivotal valve 50 using the thumb or a finger of the same hand. By pressing down on the pivotal valve 50 the locking lip 52 engages the retention lip 54. and the bottom element 59 breaks the seal 17. The pivotal valve 50 is retained in the described position by the engagement of the locking ϊp 52 and the retention lip 54. With the pivotal valve 50 in the described position, fluid may flow from the fluid container 13 into the fluid communication path 57 either through the opening 56 or through the space made between the bottom element 59 andthe fluid container 13. Once fluid has entered the fluid communication path 57. the fluid may then flow into the tubular pathway 12. and into the foam pad 16.
An alternative embodiment for the pivotal valve 50. including a locking mechanism for the pivotal valve 50. is illustrated in figures 8 and 9. Referring to figure 8. a moveable lock 88 is disposed in the pivotal valve 50 in such a way that downward rotation of the
π pivotal valve 50 is prevented when the moveable lock 88 contacts the retention lip 54. However, when the moveable lock 88 is pushed into a retention groove 88a the pivotal valve may be rotated downward so that the bottom element 59 penetrates and breaks the seal 17. An optional one-way locking mechanism may be provided. The one-way locking mechanism includes a detent 98 that is operatively associated with a slot 98a, such that when the moveable lock 88 is pushed into the retention groove 88a the detent 98 engages the slot 98a thus preventing withdrawal of the moveable lock 88 from the retention groove 88a. This is illustrated in figure 9. Once the seal 17 is broken, fluid may flow from the fluid container 13 into and through the fluid communication path 57 and into the tubular pathway 12. An alternative embodiment of the fluid applicator 10 of the present invention is provided in figures 10 through 17. Disposed through the spike 20 is a locking device 82. The locking device 82 is installed during the manufacture of the fluid applicator 10 so that the spike 20 is retained in the inactivated position ready for use. The locking device 82 is pressed inward towards the header 19. With the locking device 82 pressed inward, the spike 20 may be depressed into the activated position. Figure 1 1 depicts the locking device 82 pressed inward and the spike 20 pressed downward into the activated position. Figures 12 through 17 further illustrate how the locking device 82 functions.
Figure 12a illustrates the position of the locking device 82 prior to activation of the spike 20 also referred to as the locked position. The spike 20 is not shown in figures 12a and 12b. The locking device further includes an opening 85. and a receiving slot 84. The locking device is optionally slidably positioned on a top plane 87 defined by the skirt 14. It can be seen that in the locked position, the locking device 82 will prevent depression of the spike 20 because the locking device 82 is disposed in the spike retainer 35 so as to prevent movement of the spike 20. Therefore, to activate the fluid activator 10 in this embodiment, first the locking device 82 is pressed inward to align the hole 85 in the spike retainer 35. When the locking device i82 s pressed inward it is said to be in the unlocked position. The locking device 82 is shown in the unlocked position in figures 13a and 13b. Then the spike 20 is depressed to penetrate the seal 17 (not shown).
Figure 14a is a perspective view of the bottom of the locking device 82 of figure 12a illustrating part of a stop mechanism that facilitates positioning of the locking device 82. Figure 14b is a plan view of the top plane 87 of the skirt 14 further defining part of the stop mechanism that operatively engages the locking device 82. The locking device 82 may further define a slide channel 127 that accepts a sliding guard 128. Retention lips 123 are positioned on the bottom of the locking device 82. The retention lips 123 may operatively engage a pair of locked retention grooves 125 when the locking device 82 is in the locked position. When the locking device 82 is depressed inward into the unlocked position, the retention lips 123 may engage a pair of unlocked retention grooves 126. The sliding channel 123 and the sliding guard 128 facilitate slidably positioning the locking device 82.
Figure 15 illustrates an optional one-way lock for locking the spike 20 once the spike 20 has been depressed into the activated position. In figure 15, the spike20 is in the inactivated position. The spike 20 may further define a locking lip 132. The spike retainer 35 may further define a locking detent 133. In figure 16. the one-way locking mechanism is illustrated. In figure 16. the spike 20 is in the activated position. With the spike 20 in the activated position, the locking lip 132 engages the locking detent 133 thus preventing w ithdrawal of the spike 20.
Figure 17 is a cross-sectional view of the spike 20. As illustrated, the spike 20 defines a internal passageway that provides a fluid outlet 26. Thus, fluid may move from the container 13 (not shown), once the seal 17 (not shown) is ruptured, and into the header 19 (not shown) through the fluid outlet 26 of the spike 20. Consistent with the description above, the components of the preferred embodiment may be made from different plastic materials, although it is possible that the components would be made from the same plastic material. Different components have different desirable attributes which may be more readily attained through the use of different plastic materials. The plastic materials include polycarbonate, polystyrene, polymethylmethacrylate, polymethacrylate butadiene styrene. chlorinated polyvinylchloride. polyvinylidene chloride, and polyvinylidene fluoride, low density polyethylene, polybutyiene, and high density polyethylene. It is desirable for the spike retainer 35 to be made from a material having a sufficiently low modulus of elasticity so that the spike retainer 35 may deform slightly to accept the insertion of a spike 20 which has a retention edge 37 disposed thereon. However, the modulus of the material cannot be so low as to render the spike retainer 35 rubbery. The locking lip 132 should be flexible enough to snap into the locking detent 133. Similarly, the retention lips 123 should be flexible enough to snap into the locked retention grooves 125 when the locking device 82 is in the locked position and the unlocked retention grooves 126 when the locking device 82 is in the unlocked position. The header 19 should be sufficiently deformable to allow movement of the header 19 to facilitate positioning the foam pad 16, yet the header 19 should not be so deformable as to be rubbery.
A preferred embodiment of the fluid applicator 10 of the present invention is illustrated in figures 1 8 through 22. Referring to figure 18. a sleeve 187 is connected to a header 19. A hollow penetrator 180 is slidably disposed in the sleeve 187. The hollow penetrator further includes at least one port 1 89 and a button 183. When the header is connected to the fluid container 13. the hollow penetrator 180 may provide fluid communication between the fluid container 13 and a tubular pathway 12 when a seal 17 is ruptured. A groove lock 182 is disposed on the sleeve 187. Figure 18 presents the fluid applicator 10 in an inactivated position. In figure 19. the fluid applicator 10 is shown in an activated position with the hollow penetrator 180 having broken the seal 17. Once the seal 17 is broken, fluid may flow into and through the hollow interior of the hollow penetrator 180 and out through the port 189 into the tubular pathway 12. A fluid path is thus established between the fluid container 13 and the tubular pathway 12. The size of the port 189 may be selected to control the rate of flow of a fluid through the fluid path. To activate the fluid applicator 10. the groove lock 182 is released and the button 183 is depressed until the hollow penetrator 180 pierces and breaks the seal 17. The groove lock 182 is described in more detail below.
The groove lock 182 is further illustrated in figures 20a. 20b and 21 . In the inactivated position, depicted in figure 20a. the groove lock 182 is disposed in a slot (not shown) in the sleeve 187 and a groove (not shown) in the hollow penetrator 180, the groove being disposed in the exterior wall of the hollow penetrator 180. The groove of the hollow penetrator 180 and the slot of the sleeve 187 are aligned when the hollow penetrator is in the inactivated position so the the groove lock prevents movement, up or down, of the hollow penetrator 1 80 with respect to the sleeve 1 87. In the activated position, depicted in figure 20b. the groove lock 182 is displaced out of the slot (not shown) in the sleeve 187 and the groove (not shown) in the hollow penetrator 180. In figure 20c. a perspective view of the hollow penetrator 180 is shown illustrating the position of a groove 185 in the hollow penetrator 1 80. In figure 20d. a perspective view of the sleeve 187 is shown illustrating the position of a slot 186 in the sleeve 187. Figure 20e is a cross-sectional view of the sleeve 187 with the groove lock 182 in the locked position. In figure 20e the hollow penetrator 180 is removed to better illustrate the position of the groove lock 182 in sleeve 1 87. Therefore, to prevent movement of the hollow penetrator 1 80. the groove lock 182 is positioned in a slot 186 in the sleeve 187 and extends into a groove 185 located in the exterior wall of the hollow penetrator 180. Referring now to figure 21 the groove 185 is illustrated. When the groove lock 182 is positioned in the groove 185. the hollow penetrator 180 is prevented from slidably moving up or down the sleeve 187 because the groove lock 182 engages the slot 186 of the sleeve 187. When the groove lock 180 is displaced from the slot 186 and the groove 185, the hollow penetrator is free to move. This is illustrated in figure 22. An alternative embodiment of fluid applicator 10 is illustrated in figure 23. In this embodiment the hollow penetrator 180 has a first leak seal 235 and a second leak seal 233 each positioned in the interior of the hollow penetrator 180. The leak seal 235 functions to prevent a fluid from moving up the interior of the hollow penetrator 180 past the leak seal 235. The leak seal 233 is positioned to prevent fluid from moving up the interior of the hollow penetrator 1 80 past the leak seal 233 should the leak seal 235 fail. A slide lock 182a is disposed between the leak seal 235 and the leak seal 233 and penetrates both the sleeve 187 and the hollow penetrator 180. In an inactivated position, the slide lock 182a prevents the hollow penetrator 180 from slidably moving in the sleeve 187. This is accomplished by a stop (not shown) that is disposed between the hollow penetrator 180 and the sleeve 187. locking the hollow penetrator 180 and the sleeve 1 87 together. In an activated position, the slide lock 182a allows for movement of the hollow penetrator 180 because the stop is no longer disposed between the hollow penetrator 1 80 and the sleeve 187. The slide lock 182a is slidably moved from the inactivated position to the activated position.
Preferably the hollow penetrator 180 is manufactured from a pliable material so that the hollow penetrator 180 is self-sealing inside the sleeve 187. The hollow penetrator 182 may be manufactured from a pliable thermoplastic material, a pliable thermoset material, or from a pliable thermoplastic elastomer. Examples of the pliable material include polypropylene, high density polyethylene and polyvinyl chloride. The hollow penetrator 180 should be deformable enough to provide a seal inside the sleeve 187. yet stiff enough to allow the hollow penetrator to slidably move within the sleeve 187 and also to penetrate the seal 17. In yet additional embodiments, the header 19 may take on other shapes to facilitate either the application of various liquids, or the application of various liquids to various surfaces. Also, the foam pad 16 may be shaped to facilitate the application of a fluid to different surfaces. Examples of these additional embodiments are presented in figures 24 through 30. The foam pad 16 may be oval shaped, as illustrated in figure 24. Such a shape facilitates the application of a fluid into the skin folds of a human body, for example, when the foam pad 16 is used with a vertical movement of the fluid applicator 10 with respect to the skin fold. In figure 25 the header 19 is illustrated with an ergonomic design that facilitates easy handling of the fluid applicator 10 when applying a fluid to different areas of the human body for example. As described above, the header may be manufactured of a suitably flexible material to further aid the application of a fluid to a surface. Figure 26 illustrates a header 19 having a spray-head 182. Figure 27 illustrates a header 19 having a brush-head 192 such that fluid may pass through the header 19 and out through the brush- head 192. Such a brush-head 192 may be used for applying a hair dye. for example, to human hair. Figure 28 illustrates a header 19 having a polishing head 202. Such a polishing head 202 may be used, for example, to apply shoe polish. Figure 29 illustrates a header 19 having a nipple 212. Thus, the fluid applicator 10 may used as a sealed baby bottle when stored in the inactivated position. Once activated, a fluid may move out through the header 19 and out through the nipple 212, thus providing nourishment to an infant. Figure 30 illustrates a sucking straw 222. Thus the fluid applicator 10 may be used as a beverage drinking device for motorists, for example.
Thus it has been disclosed in embodiments and the preferred embodiment of the present invention a fluid applicator. The present invention provides a fluid applicator which allows single-finger activation. The present invention provides a fluid applicator with only one moving part. The present invention provides a locking mechanism and. thus, a fluid applicator with only two moving parts.
