Description

The present invention relates to a liquid-impregnated package.
More specifically, the present invention is excellent in storage stability and transportation stability, and can reliably impregnate a liquid-absorbing base material with a liquid during impregnation with one touch, and easily a base material impregnated with the liquid during impregnation. The present invention relates to a liquid-impregnated package having excellent usability that can be taken out.

  A package of a sheet-like article in which a liquid-absorbent sheet base material is impregnated with a liquid has been used in various fields. Although simple, when the liquid is unstable, such as a two-phase system, there is a problem that phase separation occurs in the liquid in an impregnated state and the intended purpose cannot be achieved. For example, Japanese Patent Application Laid-Open No. 08-040826 (Patent Document 1) describes a wiping tool in which a sheet is impregnated with a two-phase cleansing material, but the oil phase and the aqueous phase are separated during storage. In addition, there is a drawback that cleansing properties are lowered.

Therefore, various proposals have been made for the type of packaging in which the liquid-absorbent sheet base material and the liquid are stored in separate chambers, and the partition is broken during use to impregnate the liquid-absorbent sheet base material with liquid. Has been.
Among these, about horizontal packaging in which a liquid-absorbent sheet base material and a liquid are accommodated on the same surface, Japanese Utility Model Laid-Open No. 06-031750 (Patent Document 2), Japanese Patent Publication No. 2002-522310 (Patent Document 3), and the like. Has been proposed.

  The former is an applicator in which a bag containing a liquid and a sponge are respectively stored in two communicating portions that are communicated with each other, and the storage bag is disposed with a gap inside the packaging material of the packaging. It is a structure that is indirectly broken by pressing the enveloping material during use. For this reason, the bag breaking was very difficult and the usability was poor. For example, the bag can be broken somehow, and even if the liquid flows to the sponge side, it is permeation and diffusion only from one direction. When the sponge body is large, it is difficult to uniformly impregnate the liquid.

  Regarding the latter, a container is disclosed in which the liquid and the absorbent sheet base material are separated and stored in separate storage chambers, and the storage chambers are separated from each other by a weak seal portion. At the time of use, the liquid storage chamber is directly pressed from the outside to peel off the weak seal portion, and at the same time, the liquid is introduced into the liquid absorbent sheet base material and impregnated. However, in this structure, when a strong impact or stress is applied from the outside during storage or transportation, the weak seal part is destroyed, and there is a disadvantage that it cannot be used as a product due to unexpected impregnation. .

  Next, as for the vertical package in which the liquid-absorbent sheet base material and the liquid are stored in the vertical direction, Japanese Utility Model Laid-Open No. 02-028481 (Patent Document 4) and Japanese Utility Model Laid-Open No. 06-031751 (Patent Document 5). ), And Japanese Patent Laid-Open No. 08-038383 (Patent Document 6).

  Japanese Utility Model Laid-Open No. 02-028481 (Patent Document 4) discloses a package having a structure in which two cup-shaped containers each containing a liquid and a water-absorbing material are joined to each other through a partitioning material. However, according to this technique, a configuration is adopted in which the inner partition material is indirectly broken by pressing from the outside of the container, but there is a problem that it is difficult to destroy the partition material unless a strong force is applied.

  In Japanese Utility Model Laid-Open No. 06-031751 (Patent Document 5), a liquid glass ampule is provided in contact with the liquid absorbent sheet base material in a cylindrical package having a liquid absorbent sheet base material attached to the mouth. The structure and the structure which provided the partition in the liquid storage chamber which contact | connects a liquid-absorbent sheet base material are disclosed. At the time of use, there is a problem that the ampoule and the partition wall must be destroyed by pressing the liquid-absorbent sheet base material, which makes it difficult to destroy. In addition, the waste must be separated after use, which is very inconvenient.

  On the other hand, Japanese Patent Application Laid-Open No. 08-038383 (Patent Document 6) discloses a wiping tool in which a tissue paper and a liquid sealing bag are in contact with each other. In use, it is configured to use a separate breaker to break the liquid-filled bag, but there is a problem of forgetting to pack the breaker during manufacture, and the breaker is lost during use. This is a problem that lacks practicality.

Japanese Patent Laid-Open No. 08-040826 Japanese Utility Model Publication No. 06-031750 Japanese Patent Publication No. 2002-522310 Japanese Utility Model Publication No. 02-028481 Japanese Utility Model Publication No. 06-031751 Japanese Patent Laid-Open No. 08-038383

The present invention solves the above-described conventional problems in the liquid-impregnated package, and allows a liquid-absorbing substrate to be easily impregnated with a liquid during impregnation with a single touch when necessary, while having a compact and simple structure. Furthermore, the present invention provides a liquid-impregnated package capable of easily taking out a substrate impregnated with a liquid during impregnation.
Further, the liquid-impregnated package of the present invention can completely prevent liquid leakage due to accidental impact, excessive stress concentration, etc. during transportation and storage, and the liquid in the impregnation liquid that is the contents of the pack can be prevented.

  The present invention is a liquid-impregnated package in which a liquid during impregnation and a liquid-absorbent sheet are separately housed, and has a simple and compact structure packed in a vertically stacked state. The liquid used during impregnation is packed once in a blister pack, and the liquid absorbent sheet is set for use once correspondingly, so that it can be used disposable.

In the liquid-impregnated package of the present invention, since the liquid during impregnation is contained in a blister pack suitable for long-term storage of the contents, the contents of the liquid during impregnation will not be modified or altered unless opened. Excellent stability. In the case of a liquid which is easily phase-separated like a two-phase system, it can be used safely because it can be mixed and impregnated immediately before use.
The blister pack used for the liquid-impregnated package of the present invention has a structure in contact with the liquid-absorbent sheet, and since the liquid-absorbent sheet has cushioning properties, stress and impact acting on the blister-type pack are dispersed. Therefore, the member of the liquid storage unit and the lid sealing material are not unexpectedly destroyed, and have the required characteristics as a product.

The blister pack used in the present invention can break the seal with a built-in integral mold breaking tool, and if the seal is broken, the liquid during impregnation of the contents quickly diffuses in the thickness direction of the absorbent sheet. Therefore, it is possible to impregnate uniformly. The impregnated liquid-absorbing sheet can be easily taken out simply by peeling the sheet heat-sealed on the bottom surface. Until extraction, the liquid is not leaked because it is packed in an airtight state.
Thus, since impregnation and removal can be performed with one touch, not only is it easy to operate, but it is compact and lightweight, so it is excellent in portability and suitable for use at the destination.

  In the present invention, various agents such as external preparations for skin of various dosage forms such as cosmetics, disinfectants, antihistamines, emergency treatments, cleaning agents, hair dyes and the like can be used as the liquid during impregnation. Cosmetic liquid, disinfecting cotton, non-woven fabric, gauze, foam, etc. can be selected and used as the liquid-absorbent sheet to contain these, so that emergency treatment tools such as cosmetic applicators and disinfecting tools, wiping tools, hair dyes, etc. Applicable to a wide range of fields such as tools, cosmetic samples, and putting tools.

  The best mode for carrying out the present invention will be specifically described below.

  In the present invention, the liquid during impregnation is enclosed in a blister pack 1 made of a flexible material. The dosage form of the liquid during impregnation used in the present invention is not particularly limited, and there are various types such as a solution, emulsion, lotion, emulsion, foundation, cream, mousse, gel, ointment and the like. A compounding component is not limited, Arbitrary things can be used.

  These may be aqueous, oily, two-phase separation liquid, or emulsified. One example of the liquid during impregnation is a skin external preparation. For example, whitening, astringent, moisturizing, deodorant, anti-inflammatory, antiperspirant, anti-aging, sunscreen, makeup, skin care, rough skin prevention, cell utilization, keratin softening, exfoliation For example, for cosmetics, for cooling, for cleaning, for fragrance, for hair nourishing and hair growth. In addition, as other examples of the external preparation for skin, antihistamines, nutrients, hormonal agents, bactericides, disinfectants, oral preparations, insect repellents, emergency treatment agents, and other pharmaceuticals and quasi drugs can be used. The composition is not limited at all, and not only a single component but also a composition of any formulation can be used.

Examples of other liquids during impregnation that can be preferably used in the present invention include cleansing agents including cleansing agents, human body cleaners, and hair dyes. In addition, a cleaning agent such as a bleaching agent or a stain remover can also be used.
The viscosity of the liquid during impregnation used in the present invention is not particularly limited, but the upper limit is preferably about 100,000 mPa · sec in terms of fluidity. More preferably, it is about 90,000 mPa · sec. In the case of low viscosity, it penetrates the entire liquid-absorbing substrate, and in the case of high viscosity, it penetrates locally in the vicinity of the blister pack contact portion. It is good to use properly depending on the purpose.

The blister pack that encloses the liquid during impregnation in the present invention is made of a moldable flexible material such as plastic. It consists of a top cover material that forms a liquid storage part and a seal material that closes the bottom. A hard or semi-rigid plastic material can be used for the top cover material, and a soft sheet or a thin metal sheet can be used for the bottom seal material. Alternatively, a laminated film of plastic and metal or a vapor deposition film can be used. These are usually sealed by a heat seal method or an adhesive.

The shape of the blister pack is not limited, but for example, a hemispherical or semielliptical spherical liquid reservoir can be preferably used.
If it is not flexible, it is difficult to destroy the blister pack by pressing, and the liquid during impregnation cannot be poured out. In addition, when an external force is applied, the stress is likely to be concentrated and is easily destroyed unexpectedly. Such a blister pack can be manufactured by a known method.

In the blister pack of the present invention, preferably, a protrusion having a sharp tip integrally formed with a member on the liquid storage portion side is used as a break sharp tip, and is opposed to the bottom seal material or the liquid absorbent sheet that contacts the liquid absorbent sheet substrate. By providing in such a manner, the bottom sealing material of the blister pack can be easily broken by simply pressing from the liquid storage unit side with one touch, which is convenient. Since it is integrally formed with the cover material of the blister pack, the bottom seal material can be easily broken.
It is preferable that the tip projecting portion toward the lower part of the blister pack lid member is sharp so as to penetrate the bottom seal material and immediately impregnate the liquid absorbent sheet base material with the impregnated liquid injection. The shape is not particularly limited. More preferably, if a gap is provided between the tip of the breaker and the sheet of the seal portion, the seal portion will not be broken even if an unexpected impact is applied during transportation.
Alternatively, a brittle part may be provided in the seal part of the blister pack instead of the protruding part having a pointed end, and the content liquid can be poured out by pressing.

  If the flexibility is provided, the kind of the material constituting the blister pack is not particularly limited. For example, polyolefins such as polyethylene and polypropylene, polyesters, polyamides, polyurethanes, and melt-forming resins such as fluorine resins can be appropriately selected and used. In order to improve the storage stability of the contents, a laminated oxygen barrier material provided with an oxygen absorbing layer, an oxygen blocking layer, or the like can be used.

The liquid-impregnated package of the present invention will be described with reference to the drawings.
FIG. 1 is a conceptual perspective view of a liquid injection impregnated package 16 of the present invention, FIG. 2 is a cross-sectional view of the blister pack 1 of the present invention, and FIG. 4 and 5 show another embodiment of FIG.
In the blister pack 1 of the present invention, an upper hard or semi-rigid plastic blister pack lid member 15 and a lower blister pack bottom seal material 12 are heat sealed to form a heat seal portion 10. The blister pack liquid storage 5 is filled with an appropriate amount of the liquid 13 during impregnation. A part of the top of the blister pack 1 has a recess 14, and the lid member 15 is formed with a protruding portion 9 toward the inner space, so that the blister pack bottom seal material 12 can be easily broken during use. . The protrusion provided on the lid member 15 is not limited to that shown in FIGS. 2 and 3 as long as it breaks through the blister pack bottom seal member 12.

In FIG. 2 showing the cross-sectional view of the blister pack, the recess 14 is in the central region, but is not limited to the position of the special central region, but at the position where the bottom sealing material is broken as shown in FIGS. I just need it. The bottom sealing material 12 can be a soft or semi-rigid plastic film or a metal thin film such as an aluminum foil that can be easily broken by the protruding portion 9 having a sharp tip.
As shown in FIG. 3, the blister pack 1 is placed on the liquid-absorbent sheet substrate 2, and the bottom sealant 12 is broken and impregnated by pressing the top of the blister pack 1 with a finger during use. The liquid 13 is impregnated in the liquid absorbent sheet base material 2. Between the bottom sealing material 12 and the liquid-absorbent sheet base material, a metal or plastic mesh material can be interposed as shown in FIGS.
The blister pack 1 is packaged in a state where it is placed on the liquid-absorbent sheet substrate 2. That is, the peripheral part of the lower packaging material 7 and the upper packaging material 6 of the packaging body 16 is formed so that the substantially upper half of the blister pack protrudes from the hole 4 at the substantially central portion of the rigid or semi-rigid upper packaging material 6. Is heat-sealed to form the heat-sealed portion 11 to constitute the liquid-impregnated package 16 of the present invention.

The packaging space 8 of the liquid-impregnated packaging body 16 of the present invention actually occupies a very small volume as shown in FIG.
As described above, the liquid-impregnated packaging body 16 of the present invention is laminated in a state where the blister pack 1 is in contact with the liquid-absorbent sheet base material 2, which are the upper and lower plastic film upper packaging materials 6 and the lower packaging. The material 7 is heat sealed with the material 7 and packaged. The liquid-absorbent sheet base material 2 has cushioning properties and has an effect of absorbing external force during transportation or carrying, so that the blister pack is not inadvertently broken and the contents do not flow out.

By destroying the blister pack bottom sealing material 12 by the protruding portion 9 during use, the liquid 13 in the blister pack impregnated flows out through the broken portion of the bottom sealing material 12 and is absorbed into the liquid absorbent sheet base material 2 immediately. Impregnated. As described above, by interposing the metal or plastic mesh material 17 between the blister pack bottom sealing material 12 and the liquid-absorbent sheet base material, the permeability to the sheet base material 2 is more uniform. Can be done quickly. The structure is heat-sealed with an upper packaging material 6 formed of a hard or semi-rigid plastic film and a lower packaging material 7 formed of a soft plastic film. The package 16 having the upper packaging material 6 and the lower packaging material 7 and having the heat seal portion 11 at the periphery protrudes from the hole 4 having a small gap that allows the lid material 15 of the blister pack 1 to freely move and jumps to the outside. Not to be held. Since the gap between the cover material 15 and the hole 4 of the blister pack 1 is small, even if the blister pack 1 is torn during storage and the impregnating liquid is leaked, the liquid-absorbent sheet located below the blister pack 1 The liquid 13 during impregnation does not leak to the outside through the hole 4 due to the liquid absorption capability of the base material 2. The blister pack 1 can be uniformly diffused to the sheet base material by being arranged to such an extent that the blister pack 1 is located at a substantially central portion of the liquid absorbent sheet base material 2. The convex blister pack lid member 15 corresponding to the liquid storage part 5 of the blister pack 1 has the holes 4 formed in the upper packaging body 6, and thus prevents the blister pack 1 from dropping out. The size of the hole 4 is substantially the same as or slightly larger than the outer periphery of the blister pack lid member 15 and is preferably smaller than the outer periphery of the peripheral flange portion of the seal portion 10 between the lid member 15 and the bottom seal member 12. . Within this range, the blister pack 1 will not come out. Further, the blister pack 1 may be held in a movable state as shown in FIG. 3 with respect to the upper packaging material 15 or may be fixed, but in terms of storage stability, the blister pack 1 is in a movable state. Better.

  Further, as shown in FIG. 4, the bottom edge portion 18 of the blister pack lid member 15 is pressed against the bottom sealing member 12 to be broken, thereby impregnating the sheet base material 2 with the internal medium. At this time, the mesh material 17 may or may not be interposed, but it is preferable to impregnate the entire sheet base material 2 with a medium solution. FIG. 5 shows a mode in which the bottom sealing material 12 is broken by an edge 19 provided by an appropriate means on the ceiling portion of the blister pack lid material 15 and the sheet base material is impregnated with the medium solution through the mesh material.

The liquid-absorbent sheet base material is detachably mounted on the bottom of the liquid-impregnated package 16. If the seal portion 11 of the upper packaging material 6 formed from a hard or semi-rigid plastic film of the liquid injection-impregnated packaging body and the lower packaging material 7 composed of a soft plastic film is peeled off, the liquid absorption impregnated with the liquid during impregnation. The adhesive sheet base material can be easily taken out and can be immediately applied to the skin surface, so there is no possibility of soiling clothes. In order to facilitate peeling, it is preferable to form a weak seal structure by laminating a releasable material or blending or coating a releasable component.

  The plastic film is preferably composed of a hard or semi-rigid film on the side where the blister pack is fixed, and a soft film on the bottom side of the sheet base material. The rigid or semi-rigid film is preferably formed with an accommodating portion for the liquid-absorbent sheet by integral molding. If it does in this way, a liquid absorbing sheet will not be compressed too much, the accommodating part of a liquid absorbing sheet will act as a protective frame, and a load will not be directly loaded on a liquid absorbing sheet. The bulk thickness of the liquid-absorbent sheet is preferably equal to or less than the depth of the accommodating portion for the purpose of suppressing excessive compression.

Moreover, if an easy peeling part (not shown) is formed in a part of the heat seal part 11 of the plastic film, the grip part can be easily visually recognized, and the peeling can be easily started. Easy. The peeling start portion may be a non-adhesive portion, or may be provided with a pulling tag or tape.
The liquid-impregnated package in which a blister pack and a liquid-absorbent sheet base material are set and packaged can be used in the form of individual packages, or can be a package in which only two or more are connected. In the case where a plurality of packages are provided, it is preferable that a separation line such as a perforation line or a half cut line is provided between the packages so that the package can be separated. The size is not particularly limited, and may be a size corresponding to one use.
The blister pack, the liquid-absorbent sheet base material, and the liquid-impregnated package of the present invention formed by combining these can be designed in any shape such as a circle, an ellipse, a triangle, a square, a rectangle, and a polygon.

The liquid-absorbing sheet base material is not particularly limited as long as it is a sheet material having liquid-absorbing properties. The liquid absorption rate of the liquid absorbent sheet substrate is preferably about 50 to 500% by weight.
As the type of material, preferably one or more sheet materials selected from foamed sheets such as sponge sheets, cosmetic cotton, cosmetic cotton, disinfecting cotton, non-woven fabrics, gauze, woven fabrics, knitted fabrics and papers are used alone. Or in combination. These can be laminated and used. The materials constituting these are not particularly limited, and natural materials such as cellulose or derivatives thereof, pulp, cotton and hemp, synthetic materials such as rayon, polyamides, polyesters, acrylics and polyurethanes, or these The hydrophilization derivative | guide_body of can be illustrated.

The liquid-impregnated package of the present invention can be applied to various fields of use by combining various liquids during impregnation and various liquid-absorbent sheet base materials. Preferred forms include, for example, cosmetic applicators, first aid tools, wiping tools, hair dyeing tools, putting tools, cosmetic samples. In addition, two or more types of products related to different applications can be combined to form a set.
Although the liquid-impregnated package of the present invention can be used as it is, it can be decorated and processed into an arbitrary binding or packaging form, if necessary.
Hereinafter, the present invention will be described in more detail with reference to examples.

A polyethylene film (thickness 0.4mm) is used as the sheet material to form the lid, and a polyethylene sheet vapor-deposited with aluminum is used as the bottom sealant. The peripheral flange (outer diameter 35mmφ) is heat sealed (some are weakly sealed) Thus, a blister pack in which 4 ml of acrinol solution (1%) was encapsulated as a solution during impregnation was produced. The liquid storage part of this blister pack had a cylindrical shape with an outer diameter of 25 mmφ and a depth of 9 mm.
Next, a rectangular container (62 mm × 72 mm, depth 5.5 mm) was formed using a polyethylene film (thickness 0.35 mm) as a semi-rigid film as a base material, and a hole with a diameter of 26 mm was formed in the center. The blister pack was fitted into this hole from the liquid storage part side (because the outer diameter of the peripheral flange is larger than the hole diameter, it does not come out).
Next, sterilized disinfecting cotton (60 mm × 70 mm, bulk thickness 5 mm) was inserted as a liquid-absorbent sheet into the accommodating part (the disinfecting cotton and the peripheral rib part side of the blister pack were in contact).

Thereafter, as a soft film, a polyethylene film (thickness 0.1 mm, coated with a heat-sealable low-melting polymer) was used to cover the opening, and the periphery was sealed by a heat-sealing method (1 in 4 corners). The portion was a non-sealed portion.) After that, the outer periphery was cut to obtain a liquid-impregnated package (first aid) of the present invention.
This product was resistant to long-term storage and the blister packs were not torn when transported or carried.
Next, when injured in the field, when the liquid storage part side of this emergency treatment tool was pressed, the weak seal part was opened and the disinfectant liquid spread quickly over the entire disinfecting cotton. Next, the soft film on the opposite side is peeled off from the peeling start part, the disinfecting cotton impregnated with the disinfecting liquid is taken out, and the wound is treated. The impregnation and the removing operation can be performed only by a very simple operation. Even so, he was able to take care of himself and did not soil his clothes during operation. In addition, used products can be disposable and convenient.

Use a polyethylene film (thickness 0.4 mm) as the sheet material to form the lid, and a polyethylene sheet with aluminum deposited as the bottom sealant, and heat seal the outer edge (outer diameter 35 mmφ) (partially weak) Thus, a blister pack in which 4 ml of the emulsion sunscreen cosmetics according to the formulation shown in Table 1 was encapsulated as a liquid during impregnation was produced. The liquid storage part of this blister pack had a cylindrical shape with an outer diameter of 25 mmφ and a depth of 9 mm.
Next, a rectangular housing part (62 mm × 72 mm, depth 4 mm) was formed using a polyethylene film (thickness 0.35 mm) as a semi-rigid film as a base material, and a hole having a diameter of 26 mm was formed in the center. The blister pack was fitted into the hole from the liquid storage part side (the outer diameter of the peripheral collar part is larger than the hole diameter, so that it does not come out).

Next, a laminate of cotton non-woven fabric (60 mm × 70 mm, bulk thickness 3 mm) was inserted into the container as a liquid-absorbent sheet (the cotton non-woven fabric and the peripheral edge of the blister pack were in contact).
Then, as a soft film (coated with a heat-sealable low-melting polymer), a polyethylene film (thickness 0.1 mm) was used to cover the opening, and the periphery was sealed by a heat-sealing method (in the four corners, After the outer periphery was cut, a liquid-impregnated package (cosmetic applicator) of the present invention was obtained.
In this cosmetic applicator, the blister pack was not torn during transportation or carrying, and was able to withstand long-term storage.
Next, when the liquid storage part side of this cosmetic applicator was pressed before going out during the summer trip, the weak seal part was opened and the sunscreen emulsion in it spread quickly over the entire cotton nonwoven fabric. Next, the soft film on the opposite side is peeled off from the peeling start part, and the nonwoven fabric impregnated with the sunscreen emulsion is taken out and applied to the face. It was done quickly. As described above, even when the user is away from home, the treatment can be easily performed, and the clothes are not soiled during the operation. In addition, used products can be disposable and convenient.

A blister that uses a polyethylene film (thickness 0.4 mm) as the sheet material to form the lid, a polyethylene sheet with aluminum deposited as the bottom seal material, and heat-sealed the peripheral collar (outer diameter 35 mmφ) tightly over the entire circumference A pack was manufactured. In this blister pack, 3 ml of a sample foundation is sealed as a liquid during impregnation, and a protruding portion (protruding in the direction of the bottom sealing material) having a sharp tip is integrally formed in the liquid storage portion. The liquid storage part of this blister pack had a cylindrical shape with an outer diameter of 25 mmφ and a depth of 9 mm.
Next, a rectangular container (62 mm × 72 mm, depth 5 mm) was formed using a polyethylene film (thickness 0.35 mm) as a semi-rigid film as a base material, and a hole having a diameter of 26 mm was formed in the center. The blister pack was fitted into the hole from the liquid storage part side (the outer diameter of the peripheral collar part is larger than the hole diameter, so that it does not come out).
Next, cosmetic cotton (60 mm × 70 mm, bulk thickness 4 mm) was inserted as a liquid-absorbent sheet into the housing part (the cosmetic cotton and the peripheral heel side of the blister pack were in contact).

Thereafter, as a soft film, a polyethylene film (thickness 0.1 mm, coated with a heat-sealable low-melting polymer) was used to cover the opening, and the periphery was sealed by a heat-sealing method (1 of 4 corners). The portion was a non-sealed portion.) After that, the outer periphery was cut to obtain a liquid-impregnated package of the present invention (cosmetic sample).
This product was resistant to long-term storage and the blister packs were not torn when transported or carried.
Next, a sample of the use of this foundation was deployed at the store of a cosmetics store, and it was used according to customer requirements.
When the liquid storage part side was pressed, the protruding part broke through the lid seal part, and the oil foundation of the contents spread around the surface of the cosmetic cotton. Next, the soft film on the opposite side was peeled off from the peeling start part, the cosmetic cotton was taken out and applied to the face, impregnation and removal were performed only by a very simple operation, and the application operation could be performed consistently and quickly. It was very popular.
In this way, the work can be completed quickly in a place such as a storefront, and fingers and clothes are not soiled during operation. In addition, used products were disposable and convenient, and were well received by cosmetic stores.

A blister that uses a polyethylene film (thickness 0.4 mm) as the sheet material to form the lid, a polyethylene sheet with aluminum deposited as the bottom seal material, and heat-sealed the peripheral collar (outer diameter 35 mmφ) tightly over the entire circumference A pack was manufactured. This blister pack contains 4 ml of a moisturizing composition (0.5% by weight of sponge protein hydrolyzate, 0.5% by weight of trimethylglycine, 1.0% by weight of propylene glycol, 98% by weight of purified water) as a liquid during impregnation. A protrusion having a pointed end (protruding toward the bottom sealing material) is integrally formed. The liquid storage part of this blister pack had a cylindrical shape with an outer diameter of 25 mmφ and a depth of 9 mm.
Next, a rectangular housing part (62 mm × 72 mm, depth 4 mm) was formed using a polyethylene film (thickness 0.35 mm) as a semi-rigid film as a base material, and a hole having a diameter of 26 mm was formed in the center. The blister pack was fitted into the hole from the liquid storage part side (the outer diameter of the peripheral collar part is larger than the hole diameter, so that it does not come out).
Next, a cellulose sponge sheet (60 mm × 70 mm, bulk thickness 4 mm) was inserted as a liquid-absorbent sheet into the housing part (the cellulose sponge sheet and the peripheral collar part side of the blister pack were in contact).

Thereafter, as a soft film, a polyethylene film (thickness 0.1 mm, coated with a heat-sealable low-melting polymer) was used to cover the opening, and the periphery was sealed by a heat-sealing method (1 of 4 corners). The portion was a non-sealed portion.) After that, the outer periphery was cut to obtain a liquid-impregnated package (wiping tool) of the present invention.

Next, the soft film on the opposite side was peeled off from the peeling start part, the cellulose sponge sheet was taken out, and the butt was rubbed, so that the impregnation and removal were performed only with a very simple operation, and the coating operation could be performed consistently and quickly. It was very easy to use.
Thus, even in the case of baby care, the work could be completed quickly with one hand, and the clothes were not soiled during the operation. In addition, the used products were disposable and convenient.

A polyethylene film (thickness 0.4mm) is used as the sheet material to form the lid, and a polyethylene sheet vapor-deposited with aluminum is used as the bottom sealant. The peripheral flange (outer diameter 35mmφ) is heat sealed (some are weakly sealed) Thus, a blister pack in which 4 ml of a two-phase separation cleansing detergent was enclosed as a liquid during impregnation was produced. The liquid storage part of this blister pack had a cylindrical shape with an outer diameter of 25 mmφ and a depth of 9 mm.
Next, a rectangular housing part (62 mm × 72 mm, depth 4 mm) was formed using a polyethylene film (thickness 0.35 mm) as a semi-rigid film as a base material, and a hole having a diameter of 26 mm was formed in the center. The blister pack was fitted into this hole from the liquid storage part side (because the outer diameter of the peripheral flange is larger than the hole diameter, it does not come out).
Next, a laminate of cotton non-woven fabric (60 mm × 70 mm, bulk thickness 3 mm) was inserted into the container as a liquid-absorbent sheet (the cotton non-woven fabric and the peripheral edge of the blister pack were in contact).

Then, as a soft film (coated with a heat-sealable low-melting polymer), a polyethylene film (thickness 0.1 mm) was used to cover the opening, and the periphery was sealed by a heat-sealing method (in the four corners, One place was a non-sealed portion.) After that, the outer periphery was cut to obtain a liquid-impregnated package (wiping tool) of the present invention.
This product was resistant to long-term storage and the blister packs were not torn when transported or carried.
Next, after the inside solution of this wiping tool was shaken and mixed well on the go, when the liquid storage part side was pressed, the weak seal part was opened and the cleaning material in it spread quickly over the entire cotton nonwoven fabric. Next, the soft film on the opposite side is peeled off from the peeling start portion, the nonwoven fabric impregnated with the cleaning material is taken out, and the face is rubbed, the cleansing work is easy, and the liquid does not phase separate and is excellent in effect. there were. As described above, even when the user is away from home, the treatment can be easily performed, and the clothes are not soiled during the operation. In addition, used products can be disposable and convenient.

A polyethylene film (thickness 0.4mm) is used as the sheet material to form the lid, and a polyethylene sheet vapor-deposited with aluminum is used as the bottom sealant. The peripheral flange (outer diameter 35mmφ) is heat sealed (some are weakly sealed) Thus, a blister pack in which 4 ml of black hair dye was encapsulated as a liquid during impregnation was produced. The liquid storage part of this blister pack had a cylindrical shape with an outer diameter of 25 mmφ and a depth of 9 mm.
Next, a rectangular housing part (62 mm × 72 mm, depth 4 mm) was formed using a polyethylene film (thickness 0.35 mm) as a semi-rigid film as a base material, and a hole having a diameter of 26 mm was formed in the center.

After that, the outer periphery was cut to obtain a liquid-impregnated package (hair dyeing tool) of the present invention.
This hair dyeing device did not break the blister pack during transportation or carrying, and was able to withstand long-term storage.
Next, when the liquid storage part side of this hair dyeing tool was pressed before going out, the weak seal part was opened and the hair dye in the hair spread quickly throughout the cotton nonwoven fabric. Next, the soft film on the opposite side is peeled off from the peeling start part, and the non-woven fabric impregnated with the hair dye is taken out and applied to a conspicuous part of gray hair. Could be done consistently and quickly. Thus, the treatment can be easily performed, and the clothes are not soiled during the work. In addition, used products can be disposable and convenient.
