Description

  The present invention relates to an application tool that can be applied to the skin by impregnating a chemical solution having a medicinal effect such as a disinfecting solution or a cosmetic solution.

  Conventionally, when a chemical solution is applied to the skin or the like, a cotton swab or a cotton swab with a cotton ball attached to one end of a shaft is used. Especially in busy medical treatment, an easy-to-use swab is frequently used. This cotton swab is impregnated with a chemical solution such as disinfectant such as popidone iodine, benzalkonium chloride, benzethonium chloride, chlorhexidine gluconate, alkylaminoethylglycine hydrochloride, ethanol for disinfection, and isopropanol. For example, a chemical solution is applied by applying a cotton ball to an affected part such as a surgical site or a wound part.

  These operations are troublesome for busy users, and as a cotton swab considering the user's convenience and hygiene, the chemical solution absorbent and the chemical solution are sealed in a liquid-tight manner. In the chemical liquid absorbent packaging body separated and stored in the container, the container has a container body and a release material joined to the container body so as to be peeled from the container body when opened, There is known a chemical liquid absorbent material package in which a chemical liquid bag is joined to a peeling material and a container body so that the chemical liquid bag is torn when the release material is peeled off (see, for example, Patent Document 1).

In this package, the cotton swab and the chemical solution are sealed in separate compartments, and the composition of the cotton solution is impregnated by breaking the chemical solution compartment immediately before use. Unlike impregnating the cotton ball part with the precisely measured chemical liquid from the nozzle, the cotton ball part is impregnated with the chemical liquid by hand, and there is a problem that the chemical liquid may be spread to the shaft part.

In addition, a container main body in which a cotton swab having a cotton ball part impregnated with a chemical solution is attached to one end of a shaft and a film-like lid for sealing the upper surface opening of the container main body are provided. A swab container is known that has a ball storage recess, a shaft storage recess at the other end, and a rib that holds the swab shaft from both sides and a pillow that supports the shaft from the bottom. (For example, refer to Patent Document 2). In this swab container, the shaft of the swab is sandwiched between the ribs from both sides, so even if chemical liquid that exudes from the swab is transmitted to the side of the shaft of the swab, Since it was blocked by the contacting rib and did not reach the shaft tail, it was superior to Patent Document 1. However, depending on the conditions of transport and storage of the product, the chemical liquid that occasionally oozes from the cotton ball part may be transmitted to the shaft tail, which is not sufficient.

  In the method of impregnating a cotton ball of a cotton swab as in Patent Document 1 and Patent Document 2, in addition to the above problems, the liquid is applied evenly without drawing a circle around the site to be sterilized and without the chemical liquid being faded. In view of the disinfection method that must be performed, there is a problem that the amount of the chemical solution is inefficient with respect to the size and application area of the cotton ball. Specifically, for example, in the case of a cotton swab, the tip used for the actual application is mainly the tip of a cotton ball, and it takes time to apply a small area that can be applied at one time. In addition, despite the fact that the tip of the cotton ball is mainly used, the entire cotton ball, including the unused part of the cotton ball, must be impregnated with an antiseptic solution. Will occur. To remove the swab, the lid must be peeled off, which is troublesome. As described above, there are various problems with the swab form, and the development of a new applicator is desired.

  1A and 1B show a first embodiment of a chemical solution application tool according to the present invention, wherein FIG. 1A is a plan perspective view, FIG. 1B is a cross-sectional view taken along line XX, and FIG. It is a disassembled perspective view which shows 1st embodiment. A thick solid line in FIGS. 1 (a) and 2 indicates the bonded portion 2 bonded to the release material 40 and the first flange portion 13 of the container 10. As shown in FIGS. 1 and 2, the chemical solution applicator 1 according to the present invention includes a two-stage container 10 having a top surface opened, a chemical solution application material 20, a chemical solution 30, and a release material 40. It is a configuration.

  As shown in FIG. 1 (b), the longitudinal cross-sectional shape of the container 10 is a two-stage shape of a substantially inverted truncated cone shape that expands upward, and a first outer wall 12 that rises upward is provided around the bottom plate 11; A second outer wall 14 rising upward is connected to the peripheral edge of the first outer wall 12 via a first flange portion 13 extending horizontally outward and extends horizontally outward from the peripheral edge of the second outer wall 14. The top surface having the second flange portion 15 has a two-stage shape with an opening. Further, the peripheral edge of the second flange portion 15 has a curled portion 15a that hangs downward. Although FIG. 1B shows an example in which a flat portion is provided at the end of the curled portion 15a, it is arbitrary.

  A space surrounded by the bottom plate 11 and the first outer wall 12 of the container 10 and having an upper surface as an opening is used as a chemical solution storage unit 16. In the chemical solution storage unit 16, for example, a predetermined amount of a chemical solution 30 such as a disinfectant solution or a cosmetic solution is contained. The opening part of the chemical solution storage part 16 is covered with a release material 40 and thermally bonded to the first flange part 13 so as to be peeled off and sealed with the adhesive part 2. The bonding portion 2 has a ring shape in which the release material 40 is bonded to the first flange portion 13 in a peelable manner, and a protruding portion 2a is formed in which the inner edge of the bonding portion 2 protrudes inward. It is preferable to pressurize the first outer wall 12 by providing the protruding portion 2a because the release material 40 is easily peeled off from the protruding portion 2a. Furthermore, the opened top surface of the two-stage container 10 is covered with the chemical solution applying material 20, and the periphery or the vicinity of the peripheral edge of the chemical solution applying material 20 is thermally bonded and fixed to the second flange portion 15.

  1 and 2 show an example in which one protrusion 2a formed on the bonding portion 2 is formed, but two or more may be formed. FIG. 3 shows an example in which a plurality of protrusions 2a are formed. FIG. 3 is a plan view corresponding to FIG. 1A, in which a circle indicated by a broken line having a large diameter is the outer edge of the release material 40 and the first flange 13, and a circle indicated by a broken line having a small diameter is the first flange 13. The inner edge of FIG. 2 is a perspective plan view in which the portion indicated by a thick solid line indicates the adhesive portion 2. FIG. 3 (a) is an example in which two protrusions 2a are opposed to form a symmetrical shape, and FIG. 3 (b) is a symmetrical shape in which the bonding portion 2 is opposed to each other at approximately four equal positions. FIG. 3C shows an example in which the bonding portion 2 is formed at a position that divides into approximately five equal parts. By forming a plurality of projecting portions 2a, the release material can be easily peeled by pressing an arbitrary portion of the first outer wall 12 with a finger, which is convenient for the user.

  In addition, as shown in FIG. 1, the space surrounded by the chemical solution applying material 20, the release material 40, and the second outer wall 14 is described later. When the chemical solution application material 20 of the tool 1 is turned upside down and the chemical solution 30 leaks from the chemical solution storage portion 16 and impregnates the chemical solution application material 20, the chemical solution 30 diffuses and impregnates the chemical solution application material 20 evenly. It becomes an effective space.

  FIG. 2 is an exploded perspective view showing the first embodiment of the chemical solution applicator 1 according to the present invention. As shown in FIG. 2, the chemical solution applicator 1 stores a predetermined amount of chemical solution in the chemical solution storage portion 16 of the two-stage container 10 whose top surface is opened, and then removes the release material 40 punched into a circular shape. It mounts so that the opening part of the accommodating part 16 may be covered, the periphery or the periphery vicinity of the peeling material 40 is heat-bonded in a ring shape so that peeling is possible with the 1st flange part 13, and also the top | open top surface of the container 10 is made into a chemical | medical solution. It is the structure covered with the coating material 20 and thermally bonded to the second flange portion 15 of the two-stage container 10.

  The container 10 is used by subjecting a plastic sheet made of a thermoplastic resin to thermoforming such as vacuum forming, pressure forming, or vacuum / pressure forming. Or the container which injection-molded the thermoplastic resin is used. Examples of the thermoplastic resin include polyethylene, polypropylene, polyethylene terephthalate, polybutylene terephthalate, polyvinyl chloride, polyvinylidene chloride, ethylene-vinyl acetate copolymer, ethylene-vinyl alcohol copolymer, polylactic acid, polyacrylonitrile, polyamide. Or synthetic resins, such as a polystyrene, are mentioned. In the case of a plastic sheet, it may be a coextruded sheet obtained by coextruding one or more of the above thermoplastic resins, or a laminated sheet obtained by laminating two or more single plastic sheets with an adhesive or the like.

  Moreover, as a thickness of the plastic sheet used for the container 10, it is 0.2-2.0 mm normally, Preferably, it is 0.5-1.2 mm. When the thickness is less than 0.2 mm, the shape retention of the container 10 may be impaired. When the thickness exceeds 2 mm, the container 10 becomes too thick, and when the first outer wall 12 is pressed to peel the release material 40 from the first flange portion. Even if the first outer wall 12 is pressurized, it is difficult to be deformed, so that sufficient pressure cannot be applied and peeling may not occur.

In addition, as a material used for the chemical solution coating material 20, cloth, cotton, non-woven fabric, synthetic resin product having a porous structure, paper, or the like having chemical permeability can be used. Considering the convenience of handling, non-woven fabric is preferable. FIG. 4 shows a configuration example of the chemical solution coating material. FIG. 4 (a) shows a single layer, (b) shows two layers, and (C) shows three layers.
Thermoplastic synthetic fibers used for single-layer or multi-layer nonwoven fabric include thermoplastic polymers such as polyamide, copolymerized polyamide, polyester, copolymerized polyester, polyacrylonitrile, copolymerized polyacrylonitrile, polyolefin such as polyethylene and polypropylene. Examples thereof include fibers obtained by single, mixed or composite spinning. Furthermore, a core-sheath nonwoven fabric having the fiber as a core and a sheath made of a thermoplastic resin having thermal adhesiveness with the container 10 can be used. For example, when the surface resin to be thermally bonded of the container 10 is a polyolefin resin, a non-woven fabric having a fiber such as polyester, nylon or polypropylene as a core and a polyolefin resin such as polyethylene or polypropylene as a sheath is preferable. In addition, examples of natural fibers constituting the nonwoven fabric include cellulosic fibers such as cotton fibers and hemp fibers, animal fibers, and recycled fibers represented by pulp and rayon. The basis weight of the nonwoven fabric is ^{10g / m 2 ~300g / m 2} . A nonwoven fabric in which the thermoplastic synthetic fiber, natural fiber, and a mixture thereof are formed into a single layer or a multilayer structure of two or more layers can be used.

In the case of a multi-layer configuration, for example, as shown in FIG. 4C, the chemical solution coating material 20 has a multi-layer configuration in which a plurality of non-woven fabrics are stacked. For example, the back layer 23, the intermediate layer 22, and the surface layer 21 are formed from the container 10 side. The back layer 23 is a nonwoven fabric having thermal adhesiveness with the container 10. The intermediate layer 22 is a non-woven fabric having water retention, and the surface layer 21 is a non-woven fabric excellent in touch.
As a nonwoven fabric used for the back layer 23, a thermoplastic synthetic fiber nonwoven fabric having a material and thermal adhesiveness of the container 10 is used. As the non-woven fabric used for the surface layer 21, it is preferable to use a non-woven fabric having good touch such as flexibility because it directly contacts the skin, and the same thermoplastic synthetic fiber non-woven fabric as the back layer 23 is used. The basis weight is ^{10g / m 2 ~300g / m 2} .

As the nonwoven fabric used for the intermediate layer 22, a thermoplastic synthetic fiber nonwoven fabric made of a resin used in the surface layer, cellulose fibers such as cotton fibers and hemp fibers, or natural fiber nonwoven fabrics such as natural pulp and regenerated fibers represented by rayon, or A nonwoven fabric obtained by mixing thermoplastic synthetic fibers and natural fibers is used, but a natural fiber nonwoven fabric having excellent water retention is preferred.
The thickness of the nonwoven fabric used for the intermediate layer 22 are those determined in consideration of the storage capacity and the area of application of the chemical solution, usually, the basis weight is ^{10g / m 2 ~300g / m 2} . The intermediate layer 22 can also be a multilayer.

  Moreover, since the nonwoven fabric used for the chemical | medical solution coating material 20 adheres when the resin of the container heat-melted by heat seals, such as an ultrasonic seal, a high frequency seal, and a heat seal bar, bites into between the fibers of the nonwoven fabric, it is not necessarily attached to the nonwoven fabric. Although thermal adhesiveness is not essential, it is preferable to have thermal adhesiveness because the selection range of thermal adhesive conditions (temperature, time, pressure, etc.) becomes wider. Furthermore, the non-woven fabric is a preferred embodiment because the layer structure can make the above-mentioned roles share the respective layers, so that the selection range of the non-woven fabric is widened and the design freedom of the chemical solution coating material is widened.

In the present invention, it is important to have water retention as a property of the nonwoven fabric used for the chemical coating material. The water retention referred to in the present invention is a test method to be described later, but the chemical solution is dropped onto the chemical coating material at a constant rate, the chemical solution is impregnated into the chemical coating material, and the chemical solution becomes supersaturated and dripped from the chemical coating material. The amount of the chemical solution required until the start is expressed as a chemical solution holding amount of the non-woven fabric. The larger the chemical solution holding amount, the higher the water retention property, and the smaller the chemical solution holding amount, the lower the water retention property.
Therefore, if the water retention is low, the chemical solution is impregnated into the nonwoven fabric and permeates in a short time, so that the amount of the chemical solution retained in the nonwoven fabric is reduced, so that the suitability for chemical solution application is insufficient. An appropriate range of water retention is preferably 1 ml or more in terms of the amount of chemical solution retained.

  The release material 40 is thermally bonded and sealed to the first flange portion 13 of the container 10 so as to be peelable. Examples of the sealing method include heat sealing with a heat seal bar, ultrasonic sealing, and high frequency sealing.

The release material 40 can be used as long as it is a material that can be thermally bonded to the container 10 in a peelable manner, and a single body or a laminate of two or more layers can be used. Usually, a laminate (not shown) in which a base material and a heat-adhesive resin layer are laminated is used. As base materials, biaxially stretched plastic films such as nylon, polyethylene terephthalate, and polypropylene, films coated with barrier materials such as polyvinyl alcohol and vinylidene chloride, and inorganic substances such as silicon oxide and aluminum oxide are deposited. Film is used. For the heat-adhesive resin layer, polyethylene, ethylene / vinyl acetate copolymer, ionomer, polypropylene, easily peelable heat-adhesive resin (EPR), or the like is used after film or extrusion lamination. In addition, as a method for imparting easy peelability of EPR, a method of forming a multilayer structure in which a thin layer having a weak adhesive force is provided on the surface, a method of expressing easy peelability by a configuration such as blending a resin having low compatibility, etc. These known ones are appropriately employed. Each of the above layers is laminated by a known technique such as a dry lamination method or an extrusion lamination method to form a laminate.
Moreover, an intermediate | middle layer can also be laminated | stacked between a base material and a heat bondable resin layer. As the intermediate layer, a film used for the base material layer, an ethylene vinyl alcohol copolymer, an aluminum foil, a film on which metal such as aluminum is vapor-deposited, a synthetic paper, a non-woven fabric, and paper are used. The intermediate layer may be a multilayer of two or more layers.

  The chemical solution 30 filled and stored in the chemical solution storage unit 16 may be a solution of a medicinal component such as a disinfecting solution or a cosmetic solution, or a dispersion such as an emulsion or a suspension. For example, examples of the disinfectant include a disinfectant, a scratch agent, an anti-itch agent, and an athlete's foot drug, and examples of the cosmetic liquid include a lotion and a sunscreen liquid. Examples of the disinfectant include alcohols such as povidone iodine, chlorhexidine gluconate, benzalkonium chloride, and ethanol.

  The amount of the chemical solution 30 filled and stored in the chemical solution storage unit 16 may be appropriately determined in consideration of the use, the characteristics of the chemical solution application material (the amount of chemical solution impregnated in the chemical solution application material, the volume), and the application area. The chemical solution 30 may be colorless or colored.

  Although not shown, a configuration in which a top seal material is stacked on the chemical solution applying material 20 and the top seal material is detachably bonded to the chemical solution applying material 20 located at the second flange portion is also a preferable aspect.

  Next, a usage method will be described with reference to FIGS. As shown in FIG. 5, in the method of using the chemical solution applicator 1 of the present invention, first, the first outer wall 12 of the container 10 is sandwiched between fingers and pressed toward the center of the container 10. Then, with the increase of the internal pressure, peeling starts from the protruding portion 2a (see FIG. 1) formed on the bonding portion 2 of the peeling material 40, the peeling material 40 peels from the first flange portion 13 of the container 10, and the opening 3 is opened. It is formed. When the chemical solution application material 20 of the chemical solution application tool 1 is turned downward and the bottom plate 11 of the container 10 is turned upward, the chemical solution 30 leaks from the opening 3 and the chemical solution application material 20 is impregnated with the chemical solution application material 20 via the chemical solution diffusion portion 17. . In the case where the first outer wall 12 is sandwiched and pressed by a finger, it is preferable that one finger be a portion where the projecting portion 2a is located because the opening 3 can be formed more easily.

As shown in FIG. 5, the space surrounded by the chemical solution coating material 20, the release material 40, and the second outer wall 14, that is, the chemical solution diffusion portion 17 serves to diffuse the chemical solution 30 leaked from the chemical solution storage portion 16. The chemical solution 30 is impregnated into the chemical coating material 20 without unevenness. Thereafter, the chemical solution is applied by bringing the chemical solution application material 20 ′ impregnated with the chemical solution 30 into contact with the skin using the first outer wall 12 as a grip portion.
The length h of the vertical line from the first flange 13 forming surface to the surface formed by the inner edge of the second flange 15 is preferably 3 to 10 mm. -8 mm is more preferable.

  FIG. 6 is a cross-sectional view corresponding to the line XX of FIG. 1 showing a second embodiment of the chemical solution applicator according to the present invention. The second embodiment is different from the first embodiment in that the top seal material 50 is stacked on the chemical solution coating material 20, the point that the container 10 has the third flange portion 18, and the top seal material 50 is the first seal material 50. The third embodiment is different from the first embodiment in that the three flange portions 18 are bonded to each other, and the same reference numerals are given to omit the description. As shown in FIG. 6, the chemical solution applicator 1 ′ of the second embodiment has a curled portion 15 a in which the shape of the container 10 ′ hangs downward at the periphery of the second flange portion 15, and further from the outer edge of the curled portion 15 a. It has the 3rd flange part 18 extended a little substantially horizontally outward. Then, a top seal material 50 slightly larger than the outer edge of the third flange portion 18 of the container 10 ′ is overlaid on the chemical solution coating material 20 so as to cover the chemical solution coating material 20, and the top seal material 50 is placed on the third flange portion 18. It is the structure adhere | attached so that peeling is possible. The top seal material 50 can be detachably bonded to the chemical solution application material 20 located on the second flange portion 15, but the surface of the chemical solution application material 20 may be damaged if it is bonded by the third flange portion 18. It is preferable because it is not present. In use, first, the top seal material 50 protruding outward from the third flange portion 18 is picked, peeled off from the third flange portion 18 and removed, and thereafter used in the procedure shown in the first embodiment. Is done. Further, as another aspect, there is a method in which a plastic overcap or a chemical solution application tool is overlapped by shrink wrapping or the like on the chemical solution application material without providing the top seal material 50.

  The top seal material 50 can be used as long as it is a material that can be thermally bonded to the container or the chemical solution coating material so as to be peelable, and a single layer or a laminate of two or more layers can be used. The material used for the heat-adhesive resin layer is used. When it is set as a laminated body, it is set as the laminated body through which the base material layer and the thermoadhesive resin layer or the intermediate layer was interposed between the layers.

  FIG. 7 shows another embodiment of the container in the drug solution applicator according to the present invention, in which (A) is a perspective view, (B) is a front view as seen from the recess, and (C) is a side view.
