[0010] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or equivalent elements are designated by the same reference numerals, and redundant description will be omitted.

[0011] [Structure of patch packaging product] The patch packaged product according to the present disclosure is a product traded in the form of multiple folded patches enclosed in a single packaging bag. The patch may be any formulation that is applied to a living body, such as a poultice, tape, impregnation agent (e.g., bandage), or film preparation. The minimum number of patches enclosed in a single packaging bag may be 3, 5, 7, or 10, and the maximum number may be 30, 25, or 20. In one example, the number is determined taking into consideration the stability of the active ingredients of the patches enclosed in the packaging bag and the ease of removal of the patches. A user can remove the required number of patches one by one from the packaging bag and apply them to the desired area. In one example, the individual patches enclosed in the packaging bag are not individually packaged, thereby reducing the amount of packaging material used. In this case, the patch packaged product can be said to be a product that can reduce or minimize the environmental impact. The patch packaged product includes a single packaging bag and multiple patches. Both the packaging bag and the patch according to the present disclosure can be products that can be traded independently.

[0012] 1 to 3 are diagrams showing an example of a patch packaged product 1 and a packaging bag 10 according to an embodiment. Fig. 1 is a perspective view showing the patch packaged product 1 with the packaging bag 10 closed. Fig. 2 is a perspective view showing the patch packaged product 1 with the packaging bag 10 opened to reveal the patch 20. Fig. 3 is a plan view of the patch packaged product 1 and the packaging bag 10, and corresponds to Fig. 1.

[0013] (packaging bag) The configuration of a packaging bag 10 according to an embodiment will be described with reference to Figures 1 to 3. The packaging bag 10 is an article for enclosing a plurality of patches 20. In one example, the packaging bag 10 comprises a bag body 11, an access opening 12 formed in the bag body 11, a reinforcing label 13 that protects the outer edge of the access opening 12, a flap label 14 that functions as a lid for closing the access opening 12, and a virgin seal 15 that is provided on the flap label 14. In the present disclosure, the side on which the access opening 12 is formed is defined as the upper side of the packaging bag 10, and the opposite side is defined as the lower side of the packaging bag 10.

[0014] The bag body 11 is a flexible container for storing a plurality of folded patches 20. In one example, the bag body 11 is a laminate having at least an innermost layer made of polyethylene terephthalate (PET), polyethylene (PE), polypropylene (PP), cyclic polyolefin (COC), cycloolefin polymer, or the like; an oxygen-blocking layer made of a soft metal foil such as aluminum foil, or a vapor-deposited layer such as an aluminum vapor-deposited or silica-alumina binary vapor-deposited layer, disposed outside the innermost layer; and an outer layer made of PET, PE, PP, cellophane, paper, or the like, disposed outside the oxygen-blocking layer. The thickness of the outer layer may be 10 to 40 μm, and the thickness of the innermost layer may be 10 to 40 μm. The external shape of the bag body 11 is designed based on the shape and number of folded patches 20. In one example, the bag body 11 is generally flat and rectangular when viewed from above or below. In one example, the longitudinal end of the bag body 11 is tapered toward the tip. In one example, the dimensions of the bag body 11 are designed taking into consideration the dimensions of the folded patch 20. For example, the short side of the bag body 11 may be 6 to 15 cm, and the long side of the bag body 11 may be 10 to 20 cm. The thickness of the bag body 11 may be 5 mm to 80 mm. The bag body 11 may be provided with an openable and closable linear fastener for storing the patch 20. In this case, it becomes possible to return the removed patch 20 into the bag body 11, or to replenish the patch 20.

[0015] The access opening 12 is a hole formed in approximately the center of the top surface of the bag body 11. In one example, the shape of the access opening 12 is rectangular with rounded corners. In one example, a slit is formed in the bag body 11 along the outer edge of the access opening 12, and the flap label 14 is provided to cover the slit. When the flap label 14 is first opened, the slit portion separates from the bag body 11 while remaining attached to the adhesive layer of the flap label 14, thereby forming the access opening 12. In one example, the dimensions of the access opening 12 are designed taking into account the dimensions of the folded patch 20 (in other words, the patch 20 contained in the bag body 11), which will be described in detail later.

[0016] The reinforcing label 13 is a sheet-like member provided on the top surface of the bag body 11 so as to surround the dispensing opening 12. In one example, the inner edge of the reinforcing label 13 is designed to match the outer edge of the dispensing opening 12, and the outer edge of the reinforcing label 13 is rectangular with rounded corners. The reinforcing label 13 comprises a sheet-like substrate and an adhesive layer provided on one side of the substrate to adhere the reinforcing label 13 to the bag body 11. In one example, the substrate is made of a synthetic resin such as PET. Examples of adhesive bases contained in the adhesive layer include rubber-based adhesive bases, acrylic-based adhesive bases, silicone-based adhesive bases, and urethane-based adhesive bases. The adhesive base may be one type alone or a combination of two or more types.

[0017] The flap label 14 is a sheet-like member provided on the reinforcing label 13. The flap label 14 comprises a sheet-like substrate and an adhesive layer provided on one side of the substrate to adhere the flap label 14 to the reinforcing label 13. The substrate may be made of synthetic paper such as YUPO (registered trademark). In one example, the substrate may have a structure in which a polypropylene (PP) film is laminated on the synthetic paper. A PP film may be provided on one side of the synthetic paper and an adhesive layer on the other side. In this case, the PP film is the outermost layer of the flap label 14 and functions as the surface of the flap label 14. The thickness of the PP film may be 20 to 50 μm or 30 to 50 μm. The material of the adhesive layer of the flap label 14 is determined so that the user can repeatedly open and close the flap label 14. Examples of adhesive bases contained in the adhesive layer include rubber-based adhesive bases, acrylic-based adhesive bases, silicone-based adhesive bases, and urethane-based adhesive bases. The adhesive base may be one of these alone or a combination of two or more of them.

[0018] In one example, the flap label 14 has a generally rectangular shape with rounded corners. A portion of the first edge of the flap label 14 protrudes outward, and this protruding portion functions as a tab 14a. In one example, no adhesive layer is provided on the tab 14a. In one example, a pair of slits 14b are formed on the inside of a second edge opposite the first edge. Each slit 14b may have an overall L-shape (or an inverted L-shape). The structure of the slits 14b will be described in detail below, with the two edges perpendicular to the first and second edges referred to as side edges. Each slit 14b extends inward from a side edge of the flap label 14, then bends toward the second edge, and finally forms a small U-shape toward the side edge (i.e., outward).

[0019] A user can open the dispensing opening 12 by pinching the tab 14a and peeling the flap label 14 toward the second edge. The pair of slits 14b limit the portion of the flap label 14 that is peeled off during normal use to the portion from the first edge to the slits 14b.

[0020] The virgin seal 15 is a seal for preventing unnecessary opening of the packaging bag 10. The virgin seal 15 comprises a substrate and an adhesive layer provided on one side of the substrate. The substrate is made of, for example, paper. Examples of adhesive bases contained in the adhesive layer include rubber-based adhesive bases, acrylic-based adhesive bases, silicone-based adhesive bases, and urethane-based adhesive bases. The adhesive base may be one type alone or a combination of two or more types. In one example, the virgin seal 15 has a generally rectangular shape with rounded corners. The virgin seal 15 has dimensions sufficient to keep the flap label 14 closed; for example, the dimensions are designed to cover an area from one corner of the flap label 14 near the tab 14a to the top surface of the bag body 11.

[0021] (patch) With reference to FIG. 4, the patch 20 contained in the packaging pouch 10 will be described. FIG. 4 is a perspective view showing an example of the patch 20. In one example, the patch 20 comprises a support 21, an adhesive layer 22 formed on at least a portion of one surface of the support 21, and a release liner 23 that protects the adhesive layer 22. The active surface of the adhesive layer 22 refers to the surface that comes into contact with the user's skin when the patch 20 is in use. In one example, the shape of the patch 20 is a rectangle with rounded corners. The area of ​​the patch 20 is 1 to 300 cm 2 Or 10~200cm 2 The dimensions (length and width) of patch 20 may be 10 cm x 14 cm, 7 cm x 10 cm, or 20 cm x 14 cm. In one example, the lower limits of the length and width of patch 20 are determined taking into consideration the dosage of the active ingredient, and the upper limits of the length and width are determined taking into consideration adhesion to the skin. The thickness of patch 20 (the sum of the thicknesses of backing 21, adhesive layer 22, and release liner 23) may be 100 to 2500 μm, or may be 800 to 2200 μm.

[0022] The support 21 is a sheet-like member. The support 21 may be stretchable. For example, the material of the support 21 is selected taking into consideration various factors, such as the physical properties of the support 21 (thickness, elongation, tensile strength, ease of application, etc.), the feel upon application, the ability to seal the skin, and the migration of the active ingredient into the support 21. For example, the material of the support 21 may be a synthetic resin, such as polyolefins such as PE and PP, ethylene-vinyl acetate copolymers, vinyl acetate-vinyl chloride copolymers, polyvinyl chloride, polyamides such as nylon, polyesters such as PET, polybutylene terephthalate, and polyethylene naphthalate, cellulose derivatives, polyurethane, etc. Alternatively, the material of the support 21 may be a metal such as aluminum. For example, the material of the support 21 may be a film, sheet, porous sheet, foam sheet, fabric (e.g., woven fabric, knitted fabric, nonwoven fabric, etc.), foil, or a laminate thereof. The thickness of the support 21 may be set in the range of 5 to 1500 μm. The reason why the thickness of the support 21 is set to 5 μm or more is to facilitate handling of the patch 20. The reason why the thickness of the support 21 is set to 1500 μm or less is to prevent the hardness of the support 21 from affecting adhesiveness. For example, the thickness of the support 21 may be set in the range of 500 to 1000 μm.

[0023] The adhesive layer 22 is a layer having adhesive properties that allow it to adhere to the skin. The adhesive layer 22 may or may not contain an active ingredient. Here, the phrase "the adhesive layer contains an active ingredient" encompasses both an embodiment in which the adhesive layer contains the active ingredient and an embodiment in which the active ingredient is attached to the working surface of the adhesive layer. The adhesive layer 22 may not contain an active ingredient, but may instead be a film, gauze, or the like that contains the active ingredient, and the adhesive layer 22 may cover the film, gauze, or the like (e.g., a structure similar to a bandage). When the patch is a cataplasm, tape, impregnation agent, or film preparation, examples of the adhesive base contained in the adhesive layer 22 include rubber-based adhesive bases, acrylic-based adhesive bases, silicone-based adhesive bases, and urethane-based adhesive bases. The adhesive base may be one type alone or a combination of two or more types. If necessary, an additive may be incorporated into the adhesive layer 22. Examples of the additives include tackifiers, plasticizers, percutaneous absorption enhancers, solubilizers, stabilizers, preservatives, UV absorbers, fillers, stabilizers, and fragrances. In one example, the thickness of the adhesive layer 22 is 30 to 1500 μm (mass per unit area is 30 to 1500 g / m). 2 ), and the mass per unit area may be 300 μm to 1200 μm (300 to 1200 g / m 2 The viscosity of the pressure-sensitive adhesive layer 22 may be set in the range of 30,000 to 70,000 mPa·s in an environment of 40°C.

[0024] Release liner 23 is a sheet-like member that is releasably attached to the working surface of pressure-sensitive adhesive layer 22. The material of release liner 23 may be a synthetic resin, such as a polyolefin such as polyethylene or polypropylene, an ethylene-vinyl acetate copolymer, a vinyl acetate-vinyl chloride copolymer, polyvinyl chloride, a polyamide such as nylon, a polyester such as polyethylene terephthalate, a cellulose derivative, or polyurethane. Alternatively, release liner 23 may be made of aluminum foil, paper, or the like. Alternatively, release liner 23 may be made of a film formed from a laminate of these materials. To facilitate easy release of release liner 23, the surface of release liner 23 may be subjected to a release treatment such as silicone coating. For example, the thickness of release liner 23 may be 10 to 100 μm, and may be set within the range of 20 to 40 μm.

[0025] (Enclosing the patch in a packaging bag) The configuration relating to the encapsulation of patches 20 in packaging pouch 10 will be described with reference to Figures 5 to 8. Figure 5 is a diagram showing an example of how to fold patches 20. Figure 6 is a diagram showing an example of a method for storing multiple patches 20 in packaging pouch 10. Figure 7 is a diagram showing the dimensional relationship between access opening 12 and folded patches 20. Figure 8 is a diagram showing an example of the configuration of flap label 14.

[0026] The patch 20 contained in the packaging pouch 10 is prepared in a form in which a partial region in the longitudinal direction is folded. As shown in FIG. 5, the patch 20 may be folded so that the backing 21 is on the inside and the release liner 23 is on the outside. This partial region may occupy 1 / 2 to 1 / 4 of the longitudinal direction. When 1 / 3 of the longitudinal region is folded, a first end of the patch 20 in the longitudinal direction will be located at the center in the longitudinal direction. When the patch 20 is contained in the packaging pouch 10, this first end can function as a removal edge 29 that a user can grasp when removing the patch 20 from the packaging pouch 10. As shown in FIG. 2, in one example, the patch 20 may be contained in the packaging pouch 10 so that the release liner in the partial region faces the removal opening 12. When 1 / 3 of the longitudinal region is folded, the removal edge 29 can be located approximately in the center of the removal opening 12.

[0027] As shown in Fig. 6, in one example, each folded patch 20 is contained in the packaging pouch 10 so that the removal end 29 is visible through the removal opening 12 when viewed from above the packaging pouch 10. This means that the removal end 29 is located inside the outer edge of the removal opening 12. In this example, one-third of the patch 20 is folded in the longitudinal direction. In one example, multiple folded patches 20 are stacked inside the packaging pouch 10 so that creases appear alternately on the left and right along the stacking direction of the folded patches 20 (i.e., the height direction of the packaging pouch 10). The individual folded patches 20 are stacked so that the removal end 29 faces the removal opening 12 (i.e., so that the removal end 29 is located on the upper side).

[0028] Depending on the material of the support 21, the support 21 may be prone to sticking together due to interactions such as static electricity and friction, and when one patch 20 is removed from the packaging pouch 10, the patch 20 below it may also come out of the removal opening 12. In one example, by employing the techniques shown in Figures 5 and 6, this phenomenon can be avoided or suppressed, and as a result, the patches 20 can be reliably removed one by one.

[0029] As shown in FIG. 7 , in one example, the dimensions of the removal opening 12 are designed taking into consideration the relationship with the dimensions of the folded patch 20 contained in the packaging pouch 10. The removal opening 12 has a first length La along a first direction and a second length Lb in a second direction perpendicular to the first direction. In one example, the second length Lb is shorter than the first length La. The folded patch 20 contained in the packaging pouch 10 has a first length Lp along the first direction and a second length Lq in the second direction. In one example, the removal opening 12 is formed so that Lp / La is 1.5 to 2.5 and Lq / Lb is 1.8 to 2.8. Lp / La is the ratio of the first length Lp of the folded patch 20 to the first length La of the removal opening 12. Lq / Lb is the ratio of the second length Lq of the folded patch 20 to the second length Lb of the removal opening 12. The lower limit of Lp / La may be 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, or 2.4. The upper limit of Lp / La may be 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, or 2.5. The lower limit of Lq / Lb may be 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, or 2.7. The upper limit of Lq / Lb may be 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, or 2.8.

[0030] As shown by reference lines Ea and Ep in Fig. 8, in one example, the end of the adhesive layer of the flap label 14 on the side where the tab 14a is located is located more inward than the end of the folded patch 20 inside the packaging pouch 10. This means that when the patch packaged product 1 is viewed along the height direction, the end of the adhesive layer is located above the folded patch 20. In another example, as shown by reference lines Eb and Ep in Fig. 8, the tip of the tab 14a may be located more inward than the end of the folded patch 20 inside the packaging pouch 10. Naturally, in this case too, the end of the adhesive layer of the flap label 14 on the side where the tab 14a is located is located more inward than the end of the folded patch 20 inside the packaging pouch 10.

[0031] [How to use the patch packaging product] An example of how to use the patch package product 1 is as follows: The user pinches tab 14a of flap label 14 to peel off flap label 14 and opens dispensing opening 12. The user then pinches dispensing edge 29 of the patch 20 stacked at the top of packaging pouch 10 to remove that patch 20 from packaging pouch 10. Because dispensing edge 29 is located inside dispensing opening 12, the user can easily remove the topmost patch 20. The user unfolds the folded patch, peels off release liner 23, and applies patch 20 to the application site. The user may remove additional patches 20 from packaging pouch 10 in a similar manner and apply them to the desired site. The user then affixes flap label 14 to the top surface of bag body 11 and closes dispensing opening 12, thereby sealing the remaining patches 20 back into packaging pouch 10.

[0032] [effect] As described above, a packaging bag according to one aspect of the present disclosure comprises a bag body for storing a plurality of folded patches, a dispensing opening formed in the bag body, and a flap label for covering the dispensing opening so that the dispensing opening can be opened and closed. The dispensing opening is formed so that Lp / La is 1.5 to 2.5 and Lq / Lb is 1.8 to 2.8, where La is a first length of the dispensing opening along a first direction, Lp is a first length of the folded patch along the first direction, Lb is a second length of the dispensing opening along a second direction perpendicular to the first direction and shorter than the first length, and Lq is a second length of the folded patch along the second direction.

[0033] A patch package product according to one aspect of the present disclosure comprises a plurality of folded patches and a packaging bag containing the plurality of folded patches. The packaging bag comprises a bag body, a dispensing opening formed in the bag body, and a flap label covering the dispensing opening so that the dispensing opening can be opened and closed. The dispensing opening is formed so that Lp / La is 1.5 to 2.5 and Lq / Lb is 1.8 to 2.8, where La is a first length of the dispensing opening along a first direction, Lp is a first length of the folded patch along the first direction, Lb is a second length of the dispensing opening along a second direction perpendicular to the first direction and shorter than the first length, and Lq is a second length of the folded patch along the second direction.

[0034] In this aspect, the dimensions of the removal opening are set as described above based on the dimensions of the folded patch, making it easy to remove the patches one by one from the packaging pouch.

[0035] In another aspect of the packaging bag, the flap label may include a polypropylene film. By including a polypropylene film in the flap label, which is repeatedly opened and closed, the strength of the flap label itself is increased, thereby preventing or suppressing warping of the flap label. Therefore, the packaging bag can be reliably sealed even after the patch is removed. This reliably sealed bag contributes to maintaining the stability of the active ingredient in the patch (e.g., suppressing volatilization of the active ingredient).

[0036] In the packaging bag according to another aspect, the polypropylene film may be the outermost layer of the flap label. By disposing the high-strength polypropylene film as the outermost layer of the flap label, it is possible to more reliably avoid or suppress the phenomenon of the flap label warping due to repeated opening and closing.

[0037] In another aspect of the packaging bag, the flap label may have an adhesive layer facing the bag body and a tab formed at one end, with the end of the adhesive layer on the tab side positioned more inward than the end of the folded patch inside the bag body. In this case, the adhesive layer on the tab side, which is peeled off and attached to open and close the flap label, is positioned above the patch inside the bag body. Because the surface (top surface) of the bag body positioned above the patch is flat, the adhesive layer near the tab is stably attached to the bag body. This avoids or suppresses the flap label from unintentionally bending and opening, ensuring reliable sealing of the packaging bag even after the patch is removed. This reliable sealing contributes to maintaining the stability of the active ingredient in the patch.

[0038] In a packaging bag according to another aspect, the tip of the tab may be located inside the edge of the folded patch inside the bag body. In this case, the tab operated to open and close the flap label is located above the patch inside the bag body. Because the surface (top surface) of the bag body located above the patch is flat, the adhesive layer of the flap label stably adheres to the bag body. This avoids or suppresses the phenomenon of the flap label bending and opening unintentionally, and the packaging bag can be securely sealed even after the patch has been removed. This secure sealing contributes to maintaining the stability of the active ingredient in the patch.

[0039] The packaging bag according to another aspect may further include a reinforcing label provided so as to surround the opening. The reinforcing label strengthens the edge of the opening, so that the opening can be maintained in good condition even when the patch is repeatedly removed. For example, by avoiding or suppressing the phenomenon of the edge of the opening tearing, the packaging bag can be reliably sealed even after the patch has been removed. This reliably sealed bag contributes to maintaining the stability of the active ingredient in the patch.

[0040] In a patch package product according to another aspect, each of the plurality of folded patches may be prepared by folding a partial region in the longitudinal direction of the patch, and the plurality of folded patches may be contained in a packaging bag so that an end of the folded patch is visible from the removal opening. By folding the patch in this simple manner and containing the patch in the packaging bag, the patch can be easily removed from the packaging bag.

[0041] In a patch package product according to another aspect, each of the plurality of folded patches may be provided with a release liner that protects the adhesive layer of the patch, and each of the plurality of folded patches may be contained in the packaging pouch such that the release liner faces the removal opening in a partial region. In this case, when any two adjacent folded patches are viewed within the packaging pouch, one patch will have only its release liner facing the other patch. This can avoid or suppress the phenomenon in which, when one patch is removed from the packaging pouch, the patch below it also falls out of the removal opening, and as a result, the patches can be removed reliably one by one.

[0042] In another aspect of the patch package product, each of the folded patches comprises a backing, a pressure-sensitive adhesive layer formed on one side of the backing, and a release liner that protects the pressure-sensitive adhesive layer, and the backing may be made of a fabric, and the thickness of the backing may be 500 to 1000 μm, and the thickness of the release liner may be 20 to 40 μm. By designing the patch in this way, it becomes easy to fold the patch, and the phenomenon of the release liner unintentionally peeling off from the pressure-sensitive adhesive can be avoided or suppressed.

[0043] In a patch package product according to another aspect, multiple folded patches may be stacked inside the package bag so that creases alternate between left and right along the stacking direction of the multiple folded patches. This stacking method reduces the thickness of the multiple stacked patches, allowing the patch package product to be made smaller. In addition, because the thickness of the multiple stacked patches is uniform overall, the surface (top surface) of the bag body located above the patches can be more reliably flattened.

[0044] [Variations] The present invention has been described in detail above based on the embodiments. However, the present invention is not limited to the above embodiments. Various modifications of the present invention are possible without departing from the spirit and scope of the present invention.

[0045] The packaging bag according to the present disclosure does not need to include at least one of a reinforcing label and a virgin seal. [Explanation of symbols]
