The application device 10 described herein can store contents separately until applied to a surface. The applicator device 10 also acts as a buffer between the contents of the reservoir and the user. Further, the applicator device 10 may contain a controllable combination of different contents in at least one of its reservoirs. Additionally, certain contents may cause a reaction in the user's skin, and further, prepackaged contents ensure that the correct amount of contents is used. To use the applicator device 10, first apply pressure or force on at least one reservoir 22 in the upper portion 20 of the applicator device 10. Applying pressure or force to at least one reservoir 22 will increase the pressure within the reservoir and cause the contents of the reservoir, in a first embodiment of the invention, to exert force on at least one frangible hole of first membrane 34, The aforementioned first film 34 covers the dispensing end 30 of the upper part 20 of the applicator 10 . When sufficient force is applied to at least one frangible hole, the hole will burst and transition from a first/closed state to a second/open state, allowing the contents of the reservoir to flow into an absorbent coating 36. When the contents of the reservoir are absorbed by the application layer 36, the contents can then be applied to the surface to be applied.

Referring to FIGS. 1 and 2 , these figures illustrate an upper portion 20 of an exemplary embodiment of the applicator device 10 in top and bottom views. Briefly, the figure depicts a first reservoir 22, at least one first engagement point 26, a protective membrane 24 and a first, outer perimeter 28. In an exemplary embodiment, the reservoir 22 may include an engagement point 26 . The aforementioned engagement points 26 are located on the reservoir 22 and may be in the form of ridges, holes, or depressions in certain embodiments. These engagement points 26 can provide ergonomic comfort and, in another embodiment, can guide how and where to apply the required pressure to burst between the reservoir 22 and the coating layer 36, storing The capsule 56 of the device 22, the separation film 40 of the reservoir 22, or the fragile holes 48, 50, 52 of the first film 34 all use at least one fragile hole 48, 50, 52 to enter the coating layer 36.

The applicator device 10 is assembled by first firmly connecting the upper portion 20 with a first membrane 34 (as shown in FIG. 3 ). The upper portion 20 is sealed or welded around the perimeter 28 of the protective film 24 by heat and pressure, and is fixedly connected to the first film 34 . The aforementioned heat and pressure sealing or welding ensures that the contents of the reservoir 22 remain sealed when the applicator device 10 is not in use or in transit. Next, an absorbent coating layer 36 is fixedly connected to the first film 34 such that the first film 34 is between the coating layer 36 and the reservoir 22 . The coating layer 36 is also sealed around the perimeter 28 of the protective film 24 by heat and pressure, and is fixedly connected to the aforementioned reservoir 22 . Likewise, the heat and pressure seal serves to ensure that the contents of the reservoir 22 are absorbed by the coating layer 36 and do not leak onto the sides of the coating device 10 . In addition, the coating layer 36 is in fluid communication with the reservoir 22 such that when the contents leave the reservoir 22, they flow out of the first film 34 through at least one frangible hole 48, 50, 52 (Figs. 8A-8C). to the smear layer 36. The smear layer 36 will then be wetted by the contents 56 of the reservoir 22 and may be applied to the surface.

In an exemplary embodiment, the first membrane 34 includes at least one frangible aperture 48 , 50 , 52 that allows the contents 56 of the reservoir 22 to enter the coating layer 36 . In order to enter the aforementioned coating layer 36, it is necessary to break or burst the aforementioned at least one fragile hole 48, 50, 52. In order to break or burst the at least one frangible hole 48, 50, 52, force or pressure needs to be applied to the reservoir 22. This force or pressure, in one embodiment, may be applied directly to the engagement point 26 of the reservoir 22 . In another embodiment, force or pressure may be applied directly anywhere on the reservoir 22 . When force or pressure is applied to the reservoir 22, internal pressure will build up within the reservoir 22, subsequently causing the frangible holes 48, 50, 52 to rupture or burst.

In one embodiment, the fragile holes are a plurality of micro-perforations 48 as shown in Figure 8A. In this embodiment, the micro-perforations 48 are spaced 1-3 mm apart and ideally have a rupture or burst force of 0.5-1.0 psi. In one embodiment, the plurality of micro-perforations 48 form an X pattern. The X pattern, when torn, creates a large opening through which liquid can flow. However, in some implementations, other geometries may be used. In other embodiments, the fragile holes are a plurality of giant perforations.

In another embodiment, the fragile holes are a set of seals 50 as shown in Figure 8B. In this embodiment, the first film 34 does not have micro-perforations, but is a set of U-shaped micro-sealing strips. To make this exemplary embodiment, a piece of first film 34 is aligned with a corresponding end of the upper portion 20 of an applicator device 10 and sealed in a 2-step process. The aforementioned double layer is sealed by a first pressure with a form/fill/seal device of approximately ^7/8 of ₂₈ circumference. The device then seals the remaining ^1/8 of the perimeter ₂₈ with a weaker seal, forming a U-shaped line. By applying force or pressure to the reservoir, the contents 56 of the reservoir 22 or the air within the reservoir 22 can cause the weaker seal to rupture or burst. Once the weaker seal breaks or bursts, the contents 56 of the reservoir 22 will flow through to the smear layer 36 . In one exemplary embodiment, a force or pressure of 0.5-1.0 psi can cause a weaker seal to rupture and burst. In other implementations, the second weaker seal may be in different shapes, such as a triangle or an ellipse, but is not limited to these shapes. In yet another embodiment, the second weaker seal may be a fluid continuation of the shape of the first seal. In this embodiment, there may be an identification pattern on the upper portion 20 of the applicator 10 that points to the location of the weaker seal.

In yet another embodiment, the fragile hole is an opening 52 covered by the pull tab 54 as shown in Figure 8C. The pull tab 54 extends beyond the first, outer perimeter 28 and when pulled creates an opening 52 for the contents of the reservoir 22 to flow through to the application layer 36 . The pull tab 54 The frangible apertures 48, 50, 52 may be used with any embodiment and are configured to be displaced during use to allow fluid communication between the contents of the reservoir 22 and the coating layer 36. In another embodiment, the fragile hole is an opening 52 that is not covered by the pull tab 54 . In this embodiment, the opening 52 may include a component that allows the contents to pass through the opening 52 only when the upper portion 20 of the applicator 10 exerts a necessary amount of force or pressure. This element also allows the content to be transported in only one direction, that is, in another embodiment from the reservoir 22 to the coating layer 36 . In the aforementioned embodiment, the aforementioned elements allow the contents to be transported in only one direction, thereby preventing the reservoir 22 from being subject to backwashing and possible contamination.

The size and shape of the reservoir 22 may vary depending on the contents 56 of the reservoir 22 and the intended use of the applicator. In one embodiment, the reservoir 22 may be circular. In another embodiment, the reservoir 22 may be square or rectangular. In yet another embodiment, the aforementioned reservoir 22 may be a truncated pyramid or a truncated cone. In another implementation form, the aforementioned reservoir 22 may be "T" shaped. In some exemplary embodiments, the shape of the upper portion 20 of the applicator is rounded. An applicator device 10 having the aforementioned rounded edges is more comfortable in the user's hand. In another exemplary embodiment, the upper portion of the applicator has a square edge or a corner edge. An applicator device 10 with the aforementioned square or corner edges can minimize production waste. The overall dimensions of the applicator device 10 vary depending on the use of the applicator device 10 . In an exemplary implementation, the aforementioned application device 10 is 50.8 mm2 and can be placed in a user's hand. The foregoing are merely illustrative embodiments and should not be construed as limiting the scope of the present invention, as the shape and size of the reservoir 22 will vary depending on the internal contents and the intended use of the applicator.

Referring again to FIG. 2 , which is a bottom view of an upper portion 20 of an exemplary applicator device 10 including at least one reservoir 22 in an exemplary embodiment. In short, this figure A reservoir 22, a dispensing end 30, the protective film 24, the perimeter 28 of the protective film 24 and a first sealing area 32 are described. As mentioned above, a first film 34 is fixedly connected to the front upper portion 20 of the application device 10 . The first film 34 is fixed to the upper front portion 20 of the applicator 10 by heat and pressure sealing. The first film 34 is heat and pressure sealed to the upper portion 20 of the applicator 10 to create a first, outer seal along the perimeter 28 of the protective film 24 in the first sealing area 32 . This first, external seal ensures that the contents of the reservoir 22 are retained within the reservoir 22 until use or during transportation or storage of the applicator device.

In another embodiment, the first film 34 and at least one second separation film 40 can be sealed on the upper portion 20 of the applicator 10 by other heat welding techniques, including but not limited to: hot gas welding, heating Wedge welding, extrusion welding, hot plate welding, infrared welding and laser welding.

When applicator device 10 is ready for use, at least one frangible aperture 48, 50, 52 ruptures or bursts, as described above, transitioning said at least one frangible aperture from a first/closed state to a second/open state. When at least one frangible hole 48, 50, 52 ruptures or bursts, the contents 56 of the reservoir 22 will flow through the dispensing end 30 to the application layer 36. The aforementioned at least one frangible hole 48, 50, 52 can be located anywhere on the first and outer perimeter 28 of the upper part 20 of the applicator 10. at. In some embodiments, the at least one frangible hole 48 , 50 , 52 and other frangible holes 48 , 50 , 52 are placed in a centralized area to transport a target amount of content 56 from the reservoir 22 to the application layer 36 specific part. In some other embodiments, the at least one fragile hole 48, 50, 52 is evenly distributed in the first film 34, within the perimeter 28 of the protective film 24, so that the contents 56 of the reservoir 22 can be evenly distributed. absorbed by the smear layer 36. This embodiment may, for example, be useful in medical applications such as sterilization before surgery. For example: in one embodiment, disinfectant can be placed in the aforementioned reservoir 22 . In the same embodiment, the uniformly spaced at least one frangible hole 48, 50, 52 enables the smear layer 36 to be evenly covered with the disinfectant to ensure that the area to be cleaned before surgery is evenly covered with the disinfectant. Covered.

Referring also to FIGS. 3 and 6 , these figures are exploded views of the application device 10 of an exemplary embodiment. These figures depict an upper portion 20 of the application device 10, a first film 34 and the aforementioned application layer 36. Each of the aforementioned three elements is made from a different station of a form/fill/seal device known in the art, and then heat and vacuum sealed together. In particular, the upper part 20 of the aforementioned application device 10 is made of a roll of formed film. The formed film is a co-extruded composite material that should be impermeable to liquids, rigid enough to maintain its shape, yet flexible enough to be applied with pressure from the user's fingers. In one example, the upper portion 20 of the applicator device 10 is extruded from a thermoplastic material. For example, in some embodiments, the thermoplastic material may be polyethylene and polypropylene, polyethylene and polyamide, polypropylene and polyamide, and polyethylene carbonate. In some exemplary embodiments, the aforementioned materials may be medical grade to ensure that the applicator device meets specific standards for medical or pharmaceutical use. In some embodiments, it is necessary to ensure that the material selected to make the upper portion 20 of the applicator 10 is resistant to microbial contamination, oxidation, volatilization or moisture. Further, for some medical purposes, the content of the aforementioned application device 10 is protected Light is important. Therefore, in some exemplary embodiments, the thermoplastic material selected to make the upper portion 20 of the applicator 10 is colored or completely darkened to ensure that sunlight or light cannot reach the contents 56 of the reservoir 22 . In an exemplary embodiment, the upper portion 20 of the applicator device 10 is 5 mils thick. In another embodiment, the upper portion 20 of the applicator device 10 is 2 to 12 mils thick. In yet another embodiment, the thickness of the upper portion 20 of the applicator device 10 depends upon the specific contents 56 of the reservoir 22 as would be known by common knowledge.

A method of fabricating an application device 10 in an exemplary embodiment is as follows. A roll of material required for the upper portion 20 of the aforementioned applicator device 10 is placed into a workbench of a form/fill/seal device. The aforementioned material is unfolded into sheets and then pressed into the desired 3D shape. The forming part of the device presses a single sheet into rows and columns of the upper portion 20 of the applicator device 10 . The sheet is indexed to a second station where each reservoir is filled with a predetermined amount of content 56 . The sheet is then transferred to a third station where a roll of material for the first film is waiting. The roll of material used for the first film covers the filled container sheet and is heated and pressure sealed. The aforementioned content 56 is therefore wrapped in the upper portion 20 of the aforementioned application device 10 . The aforementioned coated upper part 20 of the coating device 10 then moves to the fourth workbench, where a roll of coating layer 36 material is waiting. The aforementioned device unfolds the application layer into a sheet and places it on the dispensing end 30 of the upper portion 20 of the aforementioned application device 10 . The aforementioned three layers are then moved to the fifth workbench as a single piece, where the aforementioned coating layer 36 is heated and pressure-sealed on the aforementioned first film 34 side. Finally, the sheet of applicator 10 is transferred to the sixth workstation, where it will be separated and cut into individual units.

Furthermore, the first film 34 and the second film 40 (separation film 40) are extruded from a thermoplastic material. For example, in some embodiments, the aforementioned thermoplastic material may be polyethylene and biaxially oriented polypropylene, polyethylene and polyester, polypropylene and biaxially oriented nylon, Polypropylene with biaxially oriented polypropylene, polypropylene with polyester, and polypropylene with biaxially oriented nylon. In some implementations, the material may be medical grade to ensure that the applicator device meets specific standards for medical or pharmaceutical use. The thickness of the polyethylene and polypropylene may be any thickness known in the art for effective specific construction of the applicator device 10 as described above. For example, in some embodiments, the thickness is about 1 to 4 mils, or in other embodiments, the thickness is about 2 mils. This thickness can be varied by one of ordinary skill in the art to optimize the storage and bursting requirements of the particular contents 56 of the reservoir 22 . In some embodiments, the biaxially oriented polypropylene, biaxially oriented nylon and polyester are ideally 50 guage, but other guage can be used to optimize the storage and rupture of the contents 56 of the reservoir 22 need.

The aforementioned absorbent coating layer 36 is an absorbent layer, generally in the form of cloth, foam/sponge or other materials suitable for impregnation. The aforementioned materials suitable for impregnation are made of polyester, polyester and regenerated cellulose fiber blends, polypropylene and cellulose. Made of pulp blend and cotton. In some exemplary embodiments, the material may be of medical grade to ensure that the applicator device meets specific standards for medical or pharmaceutical use. Further, in an exemplary embodiment, the application layer 36 may be made of surgical sponge. In another exemplary embodiment, the abrasion resistance of the coating layer 36 may vary depending on the usage of the coating device 10 . In some embodiments, the application layer 36 is cut to the perimeter 28 of the upper portion 20 of the application device 10 . Furthermore, the thickness of the aforementioned coating layer 36 may be any thickness that a person of ordinary skill in the art would understand to be applicable to a specific coating device 10 . For example, in some embodiments, the thickness is 0.2-2.5 mm or 30-65 g/m2.

The coating layer 36 can not only absorb the contents of the reservoir 22 , but in some embodiments, can also be immersed in the contents 56 and react with the contents 56 of the reservoir 22 . implemented in a In one embodiment, the coating layer 36 may be impregnated with a dry substance, such as a powder, and then react with the liquid contents of the reservoir 22 . In another embodiment, the application layer 36 is immersed in a liquid, dried and then combined with the contents 56 of the reservoir 22 for use by the applicator.

In addition, in one embodiment, the coating layer 36 is covered with a cover. The cover covering the coating layer 36 serves to prevent the coating layer 36 from being contaminated. Also, in some embodiments, the cover is used to prevent any impregnated dry contents in the coating layer 36 from reacting with the environment or any other agent. The cap can be releasably placed on the applicator device 10 in a variety of ways. In one embodiment, the cover is buckled on the application device 10 to cover the application layer 36 . In one embodiment, the protective film 24 includes a protrusion around the perimeter 28 that allows the lid to be releasably fastened in order to secure the lid in place. In another embodiment, the protrusions extending around the perimeter 28 can also be used to cover the application layer 36 with a cover using a groove and lip method. In this embodiment, the aforementioned protrusions extending around the perimeter 28 may have lips or grooves to movably engage the lid. In another embodiment, the protrusions are not integrally formed and extend around the perimeter 28 . Alternatively, the protrusions have gaps that can be provided at discontinuities in the protrusions and turned into the locking position.

In another embodiment, a threaded cap is used to detachably fix the cap on the coating layer. In this embodiment, the perimeter 28 of the applicator device 10 serves as a guide so that the threaded cap covers the applicator layer 36 . To ensure that the perimeter 28 of the applicator device 10 is strong enough to engage the threads of the threaded cap, the first sealing area 32 may be thicker in one embodiment. In another embodiment, the coating 36 has threads that engage threads within the cap. In yet another embodiment, the cover is a film covering the wet application layer 36 . In this embodiment, the lid may have elastic material around its perimeter. In an exemplary implementation, the perimeter around the perimeter The elastic material allows the cap to be stretched beyond the circumference 28 of the applicator device 10 and then return to its rest size, which is smaller than the circumference 28 of the applicator device 10 . In another embodiment, the cover is a film, and the film is movably spread on the surface of a wet smear layer 36 . In this embodiment, the cap is in close contact with the coating layer due to the hydrophilicity of the film, and therefore the cap can be peeled off from the coating layer 36 . In an exemplary embodiment, one side of the lid is movably engaged with the wet smear layer 36, while the other side is sealed to not allow any contents of the wet smear layer to flow through.

Therefore, even if the application layer 36 becomes wet, the application device 10 can still be stored and handled. An exemplary embodiment of the cap allows the application layer 36 to be immersed in liquid or gel-like content instead of solid or dry substances, further expanding the use and applicability of the application device 10 . Furthermore, the cap may be secured by any method known in the art, such as a hinge whereby the applicator device may be covered after a single use for later use.

In yet another embodiment, the lid seals the coating layer 36 in an airtight manner. The airtight seal on the applicator layer 36 makes the applicator device 10 airtight and limits the potential for contamination of the contents of the applicator device 10 and the applicator layer 36 . An exemplary embodiment with an air-tight sealing lid enables the applicator device 10 to have pharmaceutical and medical applications. In an exemplary embodiment, the hermetically sealed lid may be a foil that seals along the perimeter 28 of the reservoir 22 . The aforementioned airtight sealing cover can ensure that the smear layer 36 and the content 56 are not contaminated, and ensure the sanitary status of the smear device 10 when used in medical or pharmaceutical situations. Furthermore, the sealing using foil keeps any contents on the coated layer in the dark from light.

Briefly, a plurality of reservoirs 22a, 22b, protective film 24, perimeter 28, and engagement points 26 are described. As shown in Figure 1, in an exemplary implementation In this configuration, a plurality of reservoirs 22a, 22b are extruded from the protective film 24. The aforementioned protective film 24 thus protects from contact with the application layer 36 and facilitates use with the application device 10 . Further, a first film 34 is fixedly connected to the protective film 24 through heating and pressure sealing. The coating layer 36 is fixedly connected to the protective film 24 by heating and pressure sealing.

In one embodiment, a plurality of reservoirs 22a, 22b are used to hold the same content 56. In another embodiment, a plurality of reservoirs 22a, 22b are used to hold two different contents 56. In yet another embodiment, a plurality of reservoirs 22a, 22b are used to hold two different contents 56 that cannot be combined until the contents 56 of the applicator are used.

In an exemplary embodiment, the aforementioned separation film 40 includes at least one The frangible holes 48, 50 allow the contents of one volume 42, 44, 46 to merge with the contents 56 of another volume 42, 44, 46. In this embodiment, the pressure required to break or burst the at least one fragile hole 48, 50 of the separation film 40 may be smaller than the at least one fragile hole 48 of the first film 34. , 50 required pressure to ensure that the aforementioned separation film 40 can mix the content 56 before the content 56 flows to the absorbent coating layer 36. However, in another exemplary embodiment, the pressure required to break or burst at least one fragile hole 48, 50 of the first membrane 34 is less than that of at least one fragile hole 48, 50 of the separation film 40. Holes 48, 50. In this embodiment, after one of the contents 56 of the reservoir 22 is applied to the surface, the second contents 56 can be subsequently applied. For example, apply multiple coats of paint to the floor or use multiple coats of cleanser. Another example could be applied to multi-step application of acne medications, which requires different medications to be applied at different times. Since the reservoir 22 has a plurality of distinct volumes 42, 44, 46, the applicator can hold different medications and apply them separately by varying the pressure required to rupture or burst at least one frangible hole 48, 50.

As shown in FIGS. 7A and 7B , the aforementioned separation film 40 enables the reservoir 22 to hold a plurality of contents 56 that cannot be mixed or that need to be mixed immediately before using the applicator 10 . Furthermore, in an exemplary embodiment, the at least one separation film 40 has at least one frangible hole 48 , 50 , so that the contents 56 of the plurality of volumes 42 , 44 , 46 are mixed before being absorbed by the coating layer 36 .

Referring to Figures 16-18 and 23-25, which illustrate isometric, exploded, side elevation views of additional embodiments of the applicator device 10 of the present invention. As previously recorded and described, the application device 10 generally includes an upper part 20 , which is composed of a protective film 24 , a first film 34 and an application layer 36 . The aforementioned upper part 20 contains at least one first reservoir, that is, forming The first reservoir 22 (Figs. 16 to 18) or the plurality of reservoirs 22a, 22b (Figs. 23 to 25), at the first, outer perimeter 28a of the outer edge of the protective film 24 and at least one first reservoir 22 Or the second, inner perimeter 28b around 22a, 22b. The aforementioned application device 10 further includes a sealing layer 138 covering the application layer 36 . Extending from the periphery of the sealing layer 138 is a label or grip portion 138a.

Upper portion 20 further includes at least one engagement point 26 . As shown in the above figures, the aforementioned engagement points 26 are distributed on the outside of the reservoir 22 and may be in the form of ridges, holes or depressions in certain embodiments. The engagement point 26 can provide ergonomic comfort and, in another embodiment, can guide how and where to apply the necessary pressure to burst the capsule 56 in the reservoir 22, the reservoir 22 The frangible holes 48, 50, 52 of the diaphragm 40 or the first membrane 34. The interior volume of the aforementioned reservoir 22 may further include at least one second, dividing membrane 40 to further divide the interior volume of the reservoir 22 into smaller volumes 42, 44, 46.

The assembly of the applicator device 10 in the above figure first secures the upper part 20 of the applicator device 10 to the first film 34 through a heating and pressure process. A first, external seal or weld is formed between the protective film 24 and the first membrane 34 in an external sealing area 32a between the perimeter 28a and the outer annular dotted line as shown in FIG. 17 . A second, internal seal or weld is formed around the reservoir perimeter 28b in the internal sealing area 32a between the reservoir perimeter 28b and the inner annular dashed line in this figure. The aforementioned internal seal or weld ensures that the contents remain within the reservoir 22 when the applicator device 10 is not in use. The aforementioned second, internal seal or welding improves the dispensing of the contents of the reservoir 22 when the applicator device 10 is in use by preventing the contents of the reservoir from accumulating between the upper portion 20 and the first membrane 34 in front of the applicator device.

The first film 34 can also be sealed and welded to the protective film through other heating and welding techniques. 24, which includes but is not limited to: hot gas welding, heating wedge welding, extrusion welding, hot plate welding, infrared welding and laser welding. In another embodiment, the protective film 24 can be sealed to the first film 34 through mechanical welding technology, and the welding technology includes but is not limited to rotation welding, stirring welding, vibration welding and ultrasonic welding. In yet another embodiment, the protective film 24 is fixed to the first film 34 by electromagnetic welding technology, which includes but is not limited to resistance/implantation/electric fusion welding, induction welding, dielectric welding and microwave welding. When at least one reservoir includes first and second reservoirs 22a, 22b as shown in Figures 24 and 25, the second, inner seal includes an annular seal extending along the perimeter of the first and second reservoirs 22a, 22b, and separating The seal keeps the first and second reservoirs 22a, 22b separated. In both variations, the external seal provides a second layer of protection against leakage from reservoir 22 should the internal seal fail.

The coating layer 36 is fixedly connected to the first film 34 by a heated and pressurized seal, which is located on the perimeter 28a of the upper portion 20 . The heated and pressurized seal ensures that the contents of the reservoir 22 are absorbed by the application layer 36 and do not leak out from the sides of the application device 10 . In this arrangement, the at least one reservoir 22 and coating layer 36 are in fluid communication via a first membrane 34 such that the contents exit the reservoir 22 via at least one frangible aperture 48, 50, 52 (detailed above) Flow through the first film 34 to the aforementioned coating layer 36 . The smear layer then soaks into the contents of the reservoir 22 and can be smeared onto the surface.

Finally, the sealing layer 138 is fixedly connected to the application layer 36 . The aforementioned sealing layer 138 covers the application layer 36 and is fixedly connected to the application device 10 to keep the application layer 36 clean and free from environmental contamination before using the application device 10 . In one embodiment, the sealing layer 138 includes a sealing label and provides an additional protective barrier to prevent premature infiltration of the contents of the reservoir 22 . The sealing layer 138 is preferably foil, vinyl or paper and is fixed to the coating layer by appropriate means. 36. In one embodiment, a vinyl or foil label is sealed around the perimeter of the application layer 36 through a lamination process. The aforementioned laminate material provides the added benefit of filling the sides of the coating 36 to form a complete seal and breaking away from the coating when the label is removed. In another embodiment, the sealing layer 138 includes a paper base material, which is fixedly connected to the coating layer 36 through an adhesive, and can be peeled off to expose the coating layer 36 . With a suitable sealing layer 138, the applicator device 10 can still be stored and held even if the applicator layer 36 gets wet.

In the application device 10 shown in Figures 23 to 25, the at least one reservoir 22 includes a first and a second reservoir 22a, 22b, which can be used to hold the same content. In another embodiment, the first and second reservoirs 22a and 22b have two different contents. In yet another embodiment, the first and second reservoirs 22a and 22b have two different contents that cannot be combined until the application device 10 is used. In some implementations, multiple reservoirs 22a, 22b may provide greater control over the combination and distribution of the reservoir contents. In some embodiments, pressure or force may be applied to multiple reservoirs 22a, 22b simultaneously or one at a time. By applying pressure or force to one reservoir at a time, the contents can be controllably released from the selected reservoir 22a/22b to the coating layer 36. For example, in one embodiment, the coating layer 36 may be impregnated with a dry substance and in contact with the contents of the first or second reservoir 22a, 22b. These controls can control the reaction and interaction of substances between the reservoir 22 and the coating layer 36. In another embodiment, the contents of the reservoir must be separated until application device 10 is used. In this embodiment, the contents of the first and second reservoirs 22a and 22b are two different substances, which must be combined before application to achieve the desired effect.

19 to 20, 22, 26 and other embodiments as described above, the first membrane 34 includes at least one frangible hole 48, 50, 52 that can be in the first/closed state and the second/ The deformation between the open states allows the contents of the at least one first reservoir 22 or 22a, 22b to flow to the coating layer 36. In order to flow to the coating layer 36, at least one of the aforementioned frangible holes 48, 50, 52 must break or burst. In order to rupture or burst the at least one frangible hole 48, 50, 52, force or pressure must be applied to the reservoir 22. In one embodiment, the force or pressure may be applied directly to the engagement point 26 of the reservoir 22 . In another embodiment, the force or pressure can be applied anywhere on the reservoir. Once force or pressure is applied to the reservoir 22, the internal pressure that builds up within the reservoir 22 will cause the frangible holes 48, 50, 52 to rupture or burst.

The frangible holes shown in Figures 19 and 26 are a plurality of micro-perforations 48 with a spacing of 1 to 3 mm and ideally have a rupture or burst strength of 0.5 to 1.0 psi. In one embodiment, the plurality of micro-perforations 48 form an X or cross pattern. When the aforementioned X-shaped pattern is torn open, a huge opening is created for liquid to flow through. When applicator device 10 contains a single reservoir 22 (Fig. 17), a single microperforated frangible hole 48 is used. When the applicator device 10 includes at least one first reservoir, for example, a first and second reservoir 22a, 22b (FIG. 24), a first and second microperforated frangible aperture 48a, 48b and the respective reservoir 22a, 22b. 22b is associated and overridden. Other geometries may be used in alternative implementations. In other embodiments, the fragile holes are a plurality of giant perforations.

The frangible holes are shown in Figure 20 as a set of seals 50. In this embodiment, the first film 34 does not have micro-perforations, but is a set of U-shaped micro-sealing strips. To make this exemplary embodiment, a piece of first film 34 is aligned with the corresponding end of upper portion 20 of applicator 10 and sealed in a 2-step process. _The two layers are sealed by a first pressure with a form/fill/seal device approximately ^7/8 of the outer perimeter 28a. Then, the aforementioned device seals the remaining ^1/8 of the aforementioned circumference 28a with a weaker seal and forms a U-shaped line _. By applying force or pressure to the reservoir 22, the contents of the reservoir 22 or the gas within the reservoir 22 can cause the weaker seal to rupture or burst. Once the weaker seal breaks or bursts, the contents of reservoir 22 will flow through to smear layer 36 . In an exemplary implementation, a force or pressure of 0.5 to 1.0 psi can cause the weaker seal to rupture or burst. In other implementations, the second weaker seal may be in different shapes, such as a triangle or an ellipse, but is not limited to these shapes. In yet another embodiment, the second weaker seal may be a fluid continuation of the shape of the first seal. In this embodiment, there may be an identification pattern on the upper portion 20 of the applicator 10 that points to the location of the weaker seal.

In FIGS. 22 and 28 , the frangible hole is at least one opening 52 covered by the pull tab 54 . The pull tab 54 extends across the housing perimeter 28a and, once pulled away from the first membrane 34, opens at least one opening 52 and allows the contents of the reservoir 22 to flow to the absorbent coating 36. When the applicator device 10 includes a single reservoir 22, only one alignment is used to cover the first opening 52 of the reservoir 22. When the applicator device 10 includes at least one reservoir, for example, first and second reservoirs 22a, 22b, a first and second opening 52a, 52b are associated with and cover the respective reservoir 22a, 22b. A single pull tab 54 may be used to cover the first and second openings 52a, 52b. Pull tab 54 may be used with any embodiment of frangible apertures 48, 50, 52 and configured to provide fluid communication between reservoir 22 and application layer 36.

Referring to Figure 29, one embodiment of the present invention removes the first thin film layer from other embodiments. The application device in the figure generally includes a protective film 24, at least one reservoir 22, an application layer 36 and a sealing layer 138. The use of the sealing layer 138 allows part or all of the contents of at least one reservoir 22 to be impregnated with the application layer 36, but prevents the impregnated application layer 36 from drying out or becoming contaminated due to exposure to the external environment, or from being removed from the side of the application device 10 before use. Side leakage.

Referring to Figures 9, 10, 11 and 12, an exemplary application device 10 is illustrated. In one embodiment, the possible contents 56 of the reservoir 22 are displayed. Briefly, an embodiment of the upper portion 20 of the applicator device 10, an exemplary embodiment of the contents 56, and the reservoir 22 are described. This figure shows one embodiment of the contents 56 of the reservoir 22, which is a capsule 56. However, in some embodiments, the contents 56 of the reservoir 22 may be a liquid, a colloid, a powder, a capsule, an ampoule, a squashed pill, a crystalline solid, or a combination thereof. 9 and 10 are views of an exemplary embodiment of an applicator upper portion 20 having at least one capsule containing content 56. 11 and 12 are views of an exemplary embodiment of an applicator upper portion 20 having a plurality of capsules containing contents 56.

In some embodiments, the capsule 56 contains liquid, colloid, crystalline solid or powder. Furthermore, in some embodiments, the capsule 56 may be a soft-shell capsule made of gelatin material. In another embodiment, the capsules may be made of non-gelatin materials. In some embodiments, it may be necessary to break the capsule 56 by squeezing the reservoir 22 . In another embodiment, the capsule 56 is decomposable. In this embodiment, the decomposable capsule starts to decompose once it contacts the decomposer in the reservoir 22 . Therefore, in one embodiment of the applicator device 10, an exemplary application of the capsule 56 as the content 56 may be a capsule 56 with powder inside and a liquid located in the reservoir with the capsule 56. Once the capsule 56 is broken, the powder can react with the liquid and produce a substance that can be applied to a selected surface. In another exemplary embodiment, the reverse is also possible; the capsule 56 may contain liquid while the volume of the reservoir 22 is powder. In this embodiment, the capsule 56 is broken and the liquid can react and interact with the powder before being applied to the selected surface. However, the exemplary embodiments described above should not be construed as limiting the use of capsule 56 as the contents 56 of reservoir 22 . In the above exemplary implementations, any of the above exemplary contents 56 may be taken. generation. Furthermore, the contents 56 within the capsule 56 and the contents 56 within the volume of the reservoir 22 will determine the material and consistency of the capsule 56 to best serve the purpose of the particular applicator device 10.

In another exemplary embodiment, a capsule or ampoule containing contents 56 may be placed within a second volume of the interior volume of reservoir 22 . In this exemplary embodiment, the remaining volume of reservoir 22 may be filled with the liquid to be frozen. Once frozen, the liquid will keep the capsule or ampoule ice cold until use. The frozen liquid may be thawed immediately before use in one application, or may be thawed over time to preserve the contents of the capsule or ampoule, for example, in transit in another application. Although the above embodiments discuss the use of refrigerated liquid to keep the contents 56 of the capsule or ampoule cold, this should not be viewed as limiting the use of refrigerated liquid within the reservoir 22 . In another example, the reservoir 22 may be divided into a plurality of volumes, wherein a volume between the plurality of volumes is a frozen liquid or colloid serving as a buffer between the plurality of volumes. In this example, the refrigerated liquid may cool multiple volumes within the reservoir 22 .

In yet another exemplary embodiment, the contents 56 of the aforementioned reservoir 22 may be stored in an ampoule, which in another exemplary embodiment is located within the interior volume of the reservoir. The aforementioned ampoule can be made of glass or plastic. Traditionally, the contents of the ampoule were obtained by breaking the ampoule. However, when an ampoule is broken, glass shards may cut the user or fall into the area of the ampoule's contents during use. Therefore, certain implementations take steps to prevent such problems.

In one embodiment, for example, an ampoule is placed in a sponge. The aforementioned sponge is placed in the reservoir 22 containing the ampoule. The porosity of the sponge allows the contents 56 of the ampoule to pass through the sponge while safely retaining the glass fragments within the sponge. To break the ampoule, in one embodiment, force or pressure is applied to the sponge from both sides of the reservoir 22 to break the ampoule. In another embodiment, the sponge with the ampoule is placed at an angle in the reservoir 22 so that only Force or pressure is applied from one side of the reservoir 22 to break the ampoule and allow the contents to flow into the reservoir 22 . In addition, in some embodiments, the sponge with the ampoule may have other types of contents in the reservoir 22 . Examples of possible contents 56 are as described above.

In another embodiment, the at least one frangible hole 48 , 50 , 52 is sized to allow only minimal contents to pass through without tearing and leaving a large opening in the first film 34 . By limiting the size of the contents through at least one frangible aperture 48, 50, 52, it is not necessary in some embodiments to dispose the ampoule within the sponge. The small size of at least one frangible aperture 48, 50, 52 retains all fragments of the ampoule in the reservoir 22 while allowing the contents of the ampoule to flow through the first membrane 34 to the aforementioned coating layer 36. This embodiment also has the advantage of ensuring that the contents 56 of the reservoir 22 do not leak into the coating layer 36 until they are completely mixed with the remaining contents of the reservoir 22 .

In yet another embodiment, the ampoule is positioned fixedly at an angle in the reservoir 22 due to at least one separator membrane 40 . The at least one separator membrane 40 ensures that the ampoule is held at a specific angle to ensure that the application of force or pressure to the reservoir 22 would cause the frangible neck of the ampoule to rupture and allow the contents to escape. In another embodiment, the ampoule is placed at an angle and held in place with at least one separator membrane 40, and a hard and blunt object is fixed inside the reservoir in a position such that the hard and blunt object is placed inside the reservoir. The fragile neck of the ampoule. Therefore, applying slight force or pressure to the front of the container where the hard and blunt object is secured will contact the fragile neck of the ampoule and break it, allowing the contents to escape. The ampoule may also, in some embodiments, be positioned vertically within the reservoir 22 with its tip facing the dispensing end 30 and tightly held in place with the at least one separator membrane 40 .

Ampoules are used to help keep the contents 56 within the reservoir 22 separate, for Exemplary embodiments of applicator 20 are critical for medical or pharmaceutical applications. In some cases, in the medical or pharmaceutical fields, the application of a solution requires mixing the two solutions before use. Ampoules are often useful in this situation because they keep the substances in the same container but at the same time prevent the substances from mixing. The purpose of the ampoules within the reservoir 22 of the applicator 20 is such that multiple contents are stored within the internal volume of the reservoir but can be stored separately until use. For example, in an exemplary embodiment, the ampoule may contain a powder that is to be mixed with the liquid contained in the interior volume of reservoir 22 . After the ampoule is broken, the powder is mixed with the liquid and applied to the desired surface once the solution has had enough time to react. In another exemplary embodiment, a plurality of ampoules may be stored in the internal volume of reservoir 22, with each of the plurality of ampoules storing a different content. These exemplary implementations may be used in medical applications, such as sterilizing a body part before surgery, sterilizing tools to be used during surgery, or even sterilizing a laboratory bench. Further, illustrative embodiments may be used to apply a local anesthetic solution prepared by mixing the contents of the ampoule with the contents of the internal volume of the reservoir prior to a hospital or laboratory procedure or procedure. In summary, the use of the applicator device 10 with an ampoule may, in some embodiments, solve many storage stability issues of the contents 56 in certain medical or pharmaceutical applications.

An exemplary embodiment of an applicator 20, a reservoir 22, contents 56 as a capsule 56, and an exemplary embodiment of the contents 56 as a crystal 56 are described. The aforementioned crystal 56 may be, for example, a salt crystal in one embodiment. In an exemplary embodiment, the crystal 56 is fixed above the reservoir 22 , and the capsule 56 is located below the crystal 56 in the reservoir 22 . The aforementioned capsule 56 may, for example, contain a liquid that reacts with the crystal 56 to form a solution that is absorbed by the coating layer 36 and then coated. Apply to selected surface. In another embodiment, capsule 56 may contain a colloid or powder that reacts with the crystals to form a solution.

Illustrative embodiments of seal coating layers 36, contents 56, seal perimeter 28, and label 58 are described. 14 and 15 illustrate an exemplary embodiment in which content 56 may be stored in coating layer 36 without being connected to reservoir 22. In alternative embodiments, the contents 56 may be stored in capsule form in the coating layer 36 and also in a plurality of reservoirs 22 . In this exemplary embodiment, content 56 is stored between two coating layers 36 . The aforementioned coating layer 36 therefore has the same function as the reservoir 22, that is, it holds the contents 56 until they are ready for use. In the exemplary embodiment, contents 56 are placed within at least one capsule. The aforementioned at least one capsule is then placed between a plurality of sealing coating layers 36 . There is content 56 between the plurality of sealing coating layers 36. In some embodiments, both sides of the plurality of sealing coating layers 36 can be used. In some embodiments, the capsule must be broken in order to expose the contents 56 within the capsule. To break the capsule, in some embodiments, force or pressure must be exerted on the plurality of sealing coating layers 36 by pressing the surfaces of the plurality of sealing coating layers 36 or the contents 56 between the plurality of sealing coating layers 36 . To paint the surface. In another embodiment, the capsule is soluble in liquid. The aforementioned capsules may have the same content 56 in some embodiments or different contents 56 in other embodiments, depending on the use of the applicator device 10 . Capsules with different contents may be separated in a certain pattern, also determined by use and understood as appropriate by a person of ordinary skill. In one embodiment, a plurality of sealing coating layers 36 seal along its perimeter 28 and form the first sealing area 32 . The aforementioned first sealing area 32 ensures that the capsule does not come into contact with contaminants prior to use. Therefore, the capsule is not dissolved and Risks of prior release of contents56.

In order to further prevent contamination, in another embodiment, the sealing coating layers 36 have a label 58 fixed on the side of the sealing coating layers 36 . Figure 15 depicts an exemplary implementation of a plurality of seal coating layers 36 with a label. The aforementioned labels 58 can be placed on the sides of the plurality of application layers 36 in any manner understood by a person of ordinary skill.

In another embodiment, the aforementioned labels 58 cover all sides of the plurality of sealing coating layers 36 . In yet another embodiment, the aforementioned label 58 is placed on at least one side of the plurality of seal coating layers 36 . Furthermore, in other implementation forms, the aforementioned label 58 can be placed in other places and have different sizes and geometric shapes in a manner that can be understood by a person with ordinary knowledge. Additionally, the aforementioned labels 58 placed on the sides of the plurality of sealant layers 36 may be used for a variety of purposes, depending on the desired application and based on the knowledge of one of ordinary skill in the art. For example, in one embodiment, the aforementioned label 58 serves as an additional means of ensuring that the contents 56 are protected from contamination. In another implementation, the aforementioned tag 58 may be used for advertising. In yet another implementation form, the aforementioned label 58 can be used to present information about the contents 56 in the plurality of smear layers 36 .
