Assemble the applicator 10 first by firmly connecting the upper part 20 with a first film 34 (as shown in FIG. 3). The upper part 20 is sealed or welded to the circumference 28 of the protective film 24 by heat and pressure, and is fixedly connected to the aforementioned first film 34. The aforementioned heat and pressure sealing or welding can ensure that the applicator device 10 is not used or the contents of the reservoir 22 remain sealed during transportation. Next, an absorbent coating layer 36 is fixedly connected to the first film 34 so that the first film 34 is between the coating layer 36 and the reservoir 22. The smear layer 36 is also sealed on the circumference 28 of the protective film 24 by heat and pressure, and is fixedly connected to the aforementioned reservoir 22. Similarly, the heat and pressure seal is used to ensure that the contents of the reservoir 22 are absorbed by the smear layer 36 and will not leak liquid on the sides of the smear device 10. In addition, the aforementioned smear layer 36 is in fluid communication with the aforementioned reservoir 22, so that when the content leaves the reservoir 22, it flows out of the first film 34 through at least one fragile 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 can be applied to the surface.

In an exemplary embodiment, the first film 34 includes at least one fragile hole 48, 50, 52, which allows the contents 56 of the reservoir 22 to enter the smear layer 36. To enter the aforementioned smear layer 36, the aforementioned at least one fragile hole 48, 50, 52 needs to be broken or burst. In order to break or burst the aforementioned at least one fragile hole 48, 50, 52, force or pressure must be applied to the reservoir 22. Such force or pressure can be directly applied to the engagement point 26 of the reservoir 22 in one embodiment. In another embodiment, force or pressure can be directly applied to any place of the reservoir 22. When force or pressure is applied to the reservoir 22, internal pressure will accumulate in the aforementioned reservoir 22, which will then cause the aforementioned fragile holes 48, 50, 52 to rupture or burst.

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

In another embodiment, the aforementioned fragile holes are a set of seals 50 as shown in FIG. 8B. In this embodiment, the aforementioned first film 34 does not have micro-perforations, but is a set of micro-sealing strips with U-shaped lines.

Next, the weaker the seal means sealing the remaining _^1/8 of the circumference 28, and U-shaped line. By applying force or pressure on the reservoir, the contents 56 of the reservoir 22 or the air in the reservoir 22 can rupture or burst the weaker seal. Once the weaker seal is broken or burst, the contents 56 of the reservoir 22 will flow through to the smear layer 36. In an exemplary embodiment, a force or pressure of 0.5-1.0 psi can rupture and burst the weaker seal. In other embodiments, the second weaker seal may be in a different shape, 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 part 20 of the applicator 10 that points to the position of the weaker seal.

In yet another embodiment, the aforementioned fragile hole is an opening 52 covered by a pull tab 54 as shown in FIG. 8C. The pull tab 54 extends beyond the first, outer perimeter 28, and once pulled up, an opening 52 is created, allowing the contents of the reservoir 22 to flow to the smear layer 36. The pull tab 54 It can be used together with the fragile holes 48, 50, 52 of any embodiment, and is configured to be displaced when in use, so that the contents of the reservoir 22 and the smear layer 36 can be in fluid communication. In another embodiment, the aforementioned fragile hole is an opening 52 which is not covered by the pull tab 54. In this embodiment, the opening 52 may include an element, and the element only applies a necessary amount of force or pressure to the upper part 20 of the applicator 10 to allow the content to pass through the opening 52. This element can also enable the content to be transported in a single direction only, that is, transport from the reservoir 22 to the smear layer 36 in another embodiment.

Cladding.

3 and 6, these drawings are exploded views of the application device 10 of an exemplary embodiment. These drawings depict the upper part 20 of an application device 10, a first film 34 and the aforementioned application layer 36. Each of the aforementioned three elements is made by different worktables of a molding/filling/sealing device known in the art, and then heat-sealed and vacuum-sealed into one body. In particular, the upper part 20 of the aforementioned application device 10 is made of a roll of formed film. The molded film is a co-extruded composite material, which should be liquid impermeable, rigid enough to maintain its own shape, but flexible enough to be used under pressure from the user's fingers. In one example, the upper part 20 of the applicator 10 is formed by extruding a thermoplastic material. For example, in some implementations, the aforementioned 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 of medical grade to ensure that the applicator meets specific standards for medical or pharmaceutical use. In some implementations, it is necessary to ensure that the material selected for the upper part 20 of the applicator 10 can prevent microbial contamination, oxidation, volatilization, or moisture. Further, for some medical purposes, the content of the aforementioned smear device 10 is avoided Light is important. Therefore, in some exemplary embodiments, the aforementioned thermoplastic material selected for the upper part 20 of the applicator 10 is colored or completely darkened to ensure that the contents 56 of the reservoir 22 cannot be irradiated by sunlight or light. In an exemplary embodiment, the upper part 20 of the applicator 10 is 5 mils thick. In another embodiment, the upper part 20 of the applicator 10 is 2 to 12 mils thick. In yet another embodiment, the thickness of the upper part 20 of the applicator 10 is determined by the conventional knowledge depending on the specific content 56 of the reservoir 22.

The method of manufacturing an application device 10 in an exemplary embodiment is as follows. A roll of material required for the upper part 20 of the application device 10 is put into a workbench of a forming/filling/sealing device. Unfold the aforementioned material into a sheet, and then press it into the desired 3D shape. The forming part of the device presses a single sheet into a plurality of rows and columns of the upper part 20 of the application device 10. The sheet material is indexed to the second work station, where each reservoir is filled with a predetermined amount of content 56. The sheet is then indexed to the third work station, where it is used for a roll of the first film waiting. The roll material used in the first film covers the sheet material of the filled reservoir, and is heated and pressurized to seal. The aforementioned content 56 is thus covered in the upper part 20 of the aforementioned application device 10. The covered upper part 20 of the application device 10 is then moved to the fourth worktable, in which a roll of the application layer 36 material is waiting. The aforementioned device unfolds the coating layer into a sheet shape and places it on the dispensing end 30 of the upper part 20 of the aforementioned coating device 10. The aforementioned three layers are then moved to the fifth worktable in a single piece, where the aforementioned smear layer 36 is heated and pressurized and sealed on the aforementioned first film 34 side. Finally, the sheet material of the applicator 10 is transferred to the sixth worktable, which will be separated and cut into independent units.

Further, the first film 34 and the second film 40 (separation film 40) are extruded from a thermoplastic material. For example, in some implementations, the aforementioned thermoplastic material may be polyethylene and biaxially oriented polypropylene, polyethylene and polyester, polypropylene and biaxially oriented nylon, Polypropylene and biaxially oriented polypropylene, polypropylene and polyester, and polypropylene and biaxially oriented nylon. In some implementations, the aforementioned materials can be of medical grade to ensure that the aforementioned applicator meets specific standards for medical or pharmaceutical use. The thickness of the polyethylene and polypropylene can be any thickness used in the field for the effective specific configuration of the applicator 10 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. The thickness can be changed by a person skilled in the art to optimize the storage and rupture requirements of the specific content 56 of the reservoir 22. In some implementations, the aforementioned biaxially oriented polypropylene, biaxially oriented nylon and polyester are ideally 50 guages, but other guages can be used to optimize the storage and rupture of the contents 56 of the aforementioned 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 fibers, polypropylene and cellulose. Composed of pulp blended and cotton. In some exemplary embodiments, the aforementioned materials may be of medical grade to ensure that the aforementioned application device meets specific standards for medical or pharmaceutical use. Further, in an exemplary embodiment, the aforementioned smear layer 36 may be made of surgical sponge. In another exemplary embodiment, the aforementioned smear layer 36 may have different abrasion resistance depending on the application of the smear device 10. In some implementations, the smear layer 36 is cut to the circumference 28 of the upper part 20 of the smear device 10. Further, the thickness of the aforementioned smear layer 36 can be any thickness that can be understood by a person with ordinary knowledge in the art as applicable to a particular smear device 10. For example, in some implementations, the thickness is 0.2-2.5 mm or 30-65 g/m².

The smear layer 36 can not only absorb the content of the reservoir 22, but in some implementations, it can also be immersed in the content 56 to react with the content 56 of the reservoir 22. In one implementation In the configuration, the coating layer 36 may be impregnated with a dry substance, such as powder, and then reacted with the liquid content of the reservoir 22. In another embodiment, the aforementioned smear layer 36 is immersed in a liquid, dried, and then combined with the content 56 of the reservoir 22 for use by the applicator.

In addition, in one embodiment, the smear layer 36 is covered by a cover. The cover covering the smear layer 36 is used to prevent the smear layer 36 from being contaminated. Moreover, in some implementations, the cover is used to prevent any dry content impregnated in the smear layer 36 from reacting with the environment or any other reagents. The cover can be detachably placed on the applicator 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, in order to fix the cover at the buckle position of the cover, the protective film 24 includes a protrusion around the circumference 28, which can make the cover detachably fixed. In another embodiment, the aforementioned protrusions extending around the circumference 28 can also be covered by a cover with the smear layer 36 by the groove and lip method. In this embodiment, the aforementioned protrusion extending around the circumference 28 may have a lip or groove to movably engage the lid. In another embodiment, the aforementioned protrusion does not extend around the circumference 28 in an integral manner. Alternatively, the aforementioned protrusion has a gap, which can be arranged at a discontinuity of the protrusion and turned to the locked position.

In another embodiment, a screw cap is used to detachably fix the aforementioned cap on the coating layer. In this embodiment, the circumference 28 of the applicator 10 can be used as a guide so that the screw cap covers the applicator layer 36. In order to ensure that the circumference 28 of the applicator 10 is solid enough to engage the threads of the screw cap, in one embodiment, the first sealing area 32 may be thicker. In another embodiment, the smear layer 36 has threads and can be engaged with threads in the cap. In yet another embodiment, the aforementioned cover is a film covering the wet smear layer 36. In this embodiment, the aforementioned cover may have an elastic material around its circumference. In an exemplary implementation type, the circumference of the aforementioned perimeter The elastic material allows the cover to be stretched beyond the circumference 28 of the applicator 10 and then return to its resting size, which is smaller than the circumference 28 of the applicator 10. In another embodiment, the aforementioned cover is a film, which is movably spread on the surface of a wet smear layer 36. In this embodiment, the cover is close to the smear layer due to the hydrophilicity of the film, so the cover can be peeled off from the smear layer 36. In an exemplary embodiment, one side of the aforementioned cap is movably engaged with the wet smear layer 36, and the other side is sealed to prevent any content of the wet smear layer from flowing through.

Therefore, even if the application layer 36 is wet, the application device 10 can still be stored and held. An exemplary implementation of this cover allows the smear layer 36 to be immersed in a liquid or gel content instead of a solid or dry substance, which further expands the use and applicability of the smear device 10. In addition, the aforementioned cap can be fixed by any method known in the art, such as a hinge so that it can be covered after a single use of the applicator device for later use.

In yet another embodiment, the aforementioned cover seals the smear layer 36 in an airtight manner. The airtight seal on the smear layer 36 makes the smear device 10 airtight and limits the possibility of contamination of the contents of the smear device 10 and the smear layer 36. An exemplary embodiment with a hermetically sealed lid can make the applicator 10 have pharmaceutical and medical uses. In an exemplary embodiment of the hermetic sealing lid, the aforementioned lid may be a foil, which is sealed along the circumference 28 of the reservoir 22. The aforementioned airtight sealing cap can ensure that the smear layer 36 and the content 56 are not contaminated, and the smear device 10 is used to ensure its hygienic state in medical or pharmaceutical situations. Furthermore, the sealing foil can keep any content on the smear layer in the dark to avoid light exposure.

Referring to FIG. 4, this figure is a top view of an exemplary embodiment of the upper part 20 of the applicator 10 with a plurality of reservoirs 22a, 22b. In short, a plurality of reservoirs 22a, 22b, protective film 24, circumference 28, and engagement point 26 are described. As shown in Figure 1, an exemplary implementation In the configuration, a plurality of reservoirs 22a, 22b are extruded by the protective film 24. The aforementioned protective film 24 therefore protects from contact with the smear layer 36 and is easy to use with the smear device 10. Further, a first film 34 is fixedly connected to the protective film 24 by heating and pressurizing and sealing.

In another embodiment, the aforementioned sealing layer 138 includes a paper substrate, which is fixedly connected to the smear layer 36 by an adhesive, and can be peeled off to expose the smear layer 36. With the proper sealing layer 138, even if the application layer 36 gets wet, the application device 10 can still be stored and held.

In the application device 10 shown in FIGS. 23 to 25, the aforementioned 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 aforementioned first and second reservoirs 22a, 22b have two different contents. In yet another embodiment, the aforementioned first and second reservoirs 22a, 22b have two different contents, which cannot be combined until the applicator 10 is used. In some implementations, a plurality of reservoirs 22a, 22b can have greater control over the combination and distribution of the contents of the reservoirs. In some implementations, pressure or force can be applied to a plurality of reservoirs 22a, 22b at the same time 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 smear layer 36. For example, in one embodiment, the smear layer 36 may be immersed in a dry substance and in contact with the contents of the first or second reservoir 22a, 22b. Such control can control the reaction and interaction of substances between the reservoir 22 and the smear layer 36. In another embodiment, the contents of the aforementioned reservoir must be separated until the application device 10 is used. In this embodiment, the contents of the first and second reservoirs 22a, 22b are two different substances, which must be combined before application to achieve the desired effect.

In this embodiment, the aforementioned first film 34 does not have micro-perforations, but is a set of micro-sealing strips with U-shaped lines. To make this exemplary embodiment, a piece of first film 34 is aligned with the corresponding end of the upper part 20 of the applicator 10 and sealed in two steps. In form / fill / seal apparatus by a first pressure seal around the outer circumference 28a of the _^two-7/8. Then, the weak seal means for sealing the perimeter 28a of the remaining _^1/8, and U-shaped line. By applying force or pressure on the reservoir 22, the contents of the reservoir 22 or the gas in the reservoir 22 can rupture or burst the weaker seal. Once the weaker seal is broken or burst, the contents of the storage 22 will flow through to the smear layer 36. In an exemplary embodiment, a force or pressure of 0.5 to 1.0 psi can cause the weaker seal to rupture or burst. In other embodiments, the second weaker seal may have a different shape, such as a triangle or an ellipse, but is not limited to these shapes. In yet another embodiment, the aforementioned 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 part 20 of the applicator 10 that points to the position of the weaker seal.

The fragile holes in FIGS. 22 and 28 are at least one opening 52 covered by the pull tab 54. The pull tab 54 extends over the perimeter 28 a of the housing, and once pulled and separated from the first film 34, it will open at least one opening 52 and allow the contents of the reservoir 22 to flow to the absorbent coating layer 36. When the applicator 10 includes a single reservoir 22, only one first opening 52 of the reservoir 22 is aligned to cover the first opening 52. When the application device 10 includes at least one reservoir, for example, the first and second reservoirs 22a, 22b, a first and second opening 52a, 52b are associated with and cover the respective reservoirs 22a, 22b. A single pull tab 54 can be used to cover the first and second openings 52a, 52b. The pull tab 54 can be used in conjunction with any embodiment of the fragile holes 48, 50, and 52 and is configured to fluidly communicate between the reservoir 22 and the smear layer 36.

Referring to FIG. 29, one embodiment of the present invention removes the first thin film layer from other embodiments. The smearing device in the figure generally includes a protective film 24, at least one reservoir 22, a smearing layer 36, and a sealing layer 138. The use of the sealing layer 138 enables part or all of the contents of the at least one reservoir 22 to be impregnated with the smear layer 36, but prevents the impregnated smear layer 36 from being dried or contaminated by exposure to the external environment, or from the side of the applicator 10 before use Leaking edge.

Referring to Figures 9, 10, 11 and 12, this figure depicts an exemplary application device 10 The implementation type shows the possible contents 56 of the reservoir 22. In short, an embodiment of the upper part 20 of the applicator 10, an exemplary embodiment of the content 56 and the reservoir 22 are described. This figure shows an embodiment of the content 56 of the reservoir 22, which is a capsule 56. However, in some implementations, the content 56 of the reservoir 22 may be liquid, gel, powder, capsule, ampoule, flattened pill, crystalline solid, or a combination thereof. 9 and 10 are multiple views of an exemplary embodiment of the upper part 20 of the applicator, which has at least one capsule containing a content 56. FIGS. 11 and 12 are multiple views of an exemplary embodiment of the upper part 20 of the applicator, which has a plurality of capsules containing the contents 56.

In some embodiments, the aforementioned capsule 56 contains liquid, colloid, crystalline solid or powder. Further, in some embodiments, the aforementioned capsule 56 may be a soft shell capsule made of gelatin material. In another embodiment, the aforementioned capsule can be made of a non-gelatin material. In some implementations, it may be necessary to break the capsule 56 by squeezing the reservoir 22. In another embodiment, the aforementioned capsule 56 can be decomposed. In this embodiment, the aforementioned decomposable capsule starts to decompose as soon as it contacts the decomposing agent in the reservoir 22. Therefore, in one embodiment of the application device 10, an exemplary application of the capsule 56 as the content 56 may be a capsule 56 in which the capsule contains powder and the liquid is located in the reservoir together with the capsule 56. Once the capsule 56 is broken, the aforementioned powder can react with the aforementioned liquid and produce a substance, which can be smeared on a selected surface. In another exemplary embodiment, the opposite is also possible; the aforementioned capsule 56 may contain liquid and the volume of the reservoir 22 may contain 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 embodiment described above should not be construed as limiting the application of the capsule 56 as the content 56 of the reservoir 22. In the above-mentioned exemplary embodiment, any of the above-mentioned exemplary contents 56 can be taken generation. In addition, the content 56 in the capsule 56 and the content 56 in the volume of the reservoir 22 will determine the material and consistency of the capsule 56 to best meet the purpose of the specific application device 10.

In another exemplary embodiment, a capsule or ampoule containing contents 56 may be placed in a second volume of the internal volume of the reservoir 22. In this exemplary embodiment, the remaining volume of the reservoir 22 can be filled with the liquid to be frozen. Once frozen, the liquid will keep the capsule or ampoule ice cold until use. In one application, the frozen liquid can be thawed immediately before use, or thawed over time to preserve the contents of the capsule or ampoule, for example, during transportation in another application. Although the above embodiment discusses the use of frozen liquid to keep the contents 56 of the capsule or ampoule cold, it should not be seen as limiting the use of the frozen liquid in the reservoir 22. In another example, the reservoir 22 may be divided into a plurality of volumes, wherein one volume among the plurality of volumes is a frozen liquid or colloid, which serves as a buffer between the plurality of volumes. In this example, the aforementioned refrigerated liquid can cool a plurality of volumes in the reservoir 22.

In yet another exemplary embodiment, the contents 56 of the aforementioned reservoir 22 may be stored in an ampoule, and in another exemplary embodiment, the ampoule is located in the internal volume of the reservoir. The aforementioned ampoules can be made of glass or plastic. Traditionally, the contents of an ampoule can be obtained by breaking the ampoule. However, when the ampoule is broken, the glass shards may cut the user or fall into the area of the contents of the used ampoule. Therefore, certain implementation types take measures to prevent these problems.

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

In another embodiment, the size of the aforementioned at least one fragile hole 48, 50, 52 only allows the smallest content to pass through instead of tearing it apart, resulting in a huge opening in the first film 34. By restricting the size of the content to pass through at least one fragile hole 48, 50, 52, it is not necessary to place the ampoule in a sponge in some implementations. The small size of at least one fragile hole 48, 50, 52 can retain all the fragments of the ampoule in the reservoir 22, while allowing the contents of the ampoule to flow through the first film 34 to the aforementioned smear layer 36. This embodiment also has the advantage of ensuring that the content 56 of the reservoir 22 does not leak to the smear layer 36 until it is completely mixed with the remaining content of the reservoir 22.

In yet another embodiment, due to at least one separation membrane 40, the aforementioned ampoule is fixedly placed in the reservoir 22 at an angle. The aforementioned at least one separation membrane 40 can ensure that the ampoule is maintained at a specific angle to ensure that the application of force or pressure on the reservoir 22 will cause the fragile neck of the ampoule to rupture and allow the contents to flow out. In another embodiment, the aforesaid ampoule is placed at an angle and held in place with at least one separation membrane 40, a hard and blunt object is fixed inside the reservoir, and its placement position is such that the hard and blunt object is placed in the container. The fragile neck of the ampoule. Therefore, applying a slight force or pressure to the fixed position of the aforementioned hard and blunt object in the reservoir will touch the fragile neck of the ampoule and break it, causing the contents to flow out. The ampoule may also be placed vertically in the reservoir 22 in some embodiments, with its tip facing the dispensing end 30 and being tightly held in place with the at least one separation membrane 40.

Use ampoules to help keep the contents 56 in the reservoir 22 separated, for The exemplary embodiment of the applicator 20 is very important for medical or pharmaceutical use. In some cases, in the medical or pharmaceutical fields, the application of the solution requires mixing the two solutions before use. Ampoules are often useful in this situation because they keep the substance in the same container, but at the same time prevent the substance from mixing. The purpose of the ampoule in the reservoir 22 of the applicator 20 is to store a plurality of contents in 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 will be mixed with the liquid contained in the internal volume of the reservoir 22. After the ampoule is broken, the powder is mixed with the liquid, and once the solution has enough time to react, it can be applied to the desired surface. In another exemplary embodiment, a plurality of ampoules may be stored in the internal volume of the reservoir 22, wherein each of the plurality of ampoules stores different contents. These exemplary implementation types can be used in medical applications, such as disinfecting a part of the body before surgery, disinfecting tools to be used during surgery, or even disinfecting laboratory workbenches. Further, the exemplary embodiment can be used to apply a local anesthetic solution, which is prepared by mixing the contents of the ampoule with the contents of the internal volume of the reservoir before surgery or treatment in a hospital or laboratory. In short, the application of the applicator 10 with an ampoule can solve many storage stability problems of the content 56 in specific medical or pharmaceutical applications in some embodiments.
