TECHNICAL FIELD OF THE INVENTION
The present invention relates to a face pack sheet.
[0002]
[Prior art]
In the packaging bag of Patent Document 1, the inside is divided into two chambers, a first face pack sheet is stored in a first chamber, and a lotion is stored in a second chamber. When using the face pack sheet, the peeling adhesive part separating the two chambers is peeled off by pressing from the outside, and then the lotion in the second chamber is pushed into the first chamber on the sheet side to bring the sheet into a wet state. Then, one end of the packaging bag is opened and the sheet is taken out.

[0004]
[Problems to be solved by the invention]
According to Patent Literature 1, since the face pack sheet and the lotion are separately stored in each chamber of the package, the face pack sheet can be kept in a dry state until immediately before use. Therefore, propagation of various bacteria caused by the face pack sheet being wet for a long time can be effectively prevented, and the cleanliness and safety of the pack sheet can be improved.
[0005]
However, after applying pressure to the packaging bag to peel off the peeling adhesive part, the lotion is squeezed from that part into the first chamber on the sheet side, so that the lotion spreads widely in the first chamber and to every corner. Easy to deploy. As a result, there is a disadvantage that a large amount of useless lotion that does not contribute to the wetting of the face pack sheet remains in the packaging bag. In particular, the peeled adhesive portion is easily peeled from both ends. In this case, the lotion in the second chamber is spread from both ends of the first chamber, so that a large amount of useless lotion that does not contribute to wetting tends to remain.
[0006]
An object of the present invention is to make it possible to efficiently impregnate the face pack sheet body with the lotion in the packaging bag without waste, so that it is not necessary to store the lotion in excess of the required amount, thereby reducing the cost of the product. It is an object of the present invention to provide a face pack sheet that can contribute to the development of a device. SUMMARY OF THE INVENTION An object of the present invention is to provide a face pack sheet excellent in usability, in which the operation of opening the inner bag containing the lotion and the subsequent operation of squeezing the lotion can be performed smoothly.
[0007]
An object of the present invention is to keep the face pack sheet main body in a dry state until immediately before use, so that it is possible to effectively prevent the growth of various bacteria caused by the face pack sheet main body being in a wet state for a long time, It is to provide a face pack sheet excellent in cleanliness and safety. SUMMARY OF THE INVENTION An object of the present invention is to provide a face pack sheet which can minimize the amount of additives such as preservatives for a lotion and is excellent in safety in that respect.
[0008]
[Means for Solving the Problems]
In the face pack sheet of the present invention, as shown in FIG. 1, a dry face pack sheet main body 2 and an inner bag 3 containing a lotion 4 are hermetically stored inside an outer bag 1. As shown in FIG. 3, the inner bag 3 is opened by external pressure over the outer bag 1 so that the face pack sheet body 2 is impregnated with the lotion 4 in the inner bag 3. The outer bag 1 and the inner bag 3 are made of a flexible and water-impermeable plastic film in a flat shape, and as shown in FIG. 2, the face pack sheet body 2 is folded flat. The face pack sheet main body 2 and the inner bag 3 are stored and held in the outer bag 1 in a state where the inner bag 3 is overlaid on one flat surface.
[0009]
Specifically, the inner bag 3 is formed by joining four peripheral portions of these films to each other in a state where two left and right horizontally long plastic films are opposed to each other. The four peripheral edges of the film can be joined by heat sealing. Then, as shown in FIG. 3, it is desired that the seal width W1 of at least one of the left and right joints 6a of the inner bag 3 is set to be smaller than the seal width W2 of the front and rear joints 6b.
[0010]
Alternatively, as shown in FIGS. 5 and 6, at least one of the left and right joints 6a of the inner bag 3 may be provided with an easily breakable portion 9 having a narrow seal width at at least one place. In this case, the easily breakable portion 9 can be set at a central portion in the front and rear direction of the joining portion 6a.
[0011]
Alternatively, the innermost layer of the composite plastic film constituting the inner bag 3 is desirably an easy-peel film so as to be easily opened.
[0012]
The face pack sheet body 2 and / or the lotion 4 are desirably sterilized. A specific example of such a sterilization treatment is, for example, a heat sterilization treatment at a temperature of about 85 ° C. for 30 minutes to 2 hours. The sterilization process for the lotion 4 may be performed before or after filling the inner bag 4. It is desirable that the lotion 4 does not contain any preservative or bactericide.
[0013]
Effects of the Invention
According to the present invention, in a state where the inner bag 3 is stacked on the flat surface of the face pack sheet body 2 folded flat, these sheet bodies 2 and the inner bag 3 are stored in the outer bag 1 in a sealed manner. Since the holding form is adopted, the lotion 4 squeezed out of the inner bag 3 by pressing the outer bag 1 is instantaneously impregnated in the sheet body 2 immediately below. Therefore, as in the embodiment shown in Patent Document 1, the lotion 4 is not spread and spread to all corners in the outer bag 1 and remains, and the lotion 4 in the outer bag 1 is efficiently used without waste. 2 can be impregnated. Therefore, it is only necessary to store the lotion 4 in the inner bag 3 in a necessary minimum amount, and it is possible to reduce the overall manufacturing cost. If the face pack sheet main body is folded into a tablet shape as in Patent Literature 1, it is necessary to take out the sheet main body from the bag and then expand it, which is inconvenient. In this regard, if the face pack sheet body 2 is folded flat as in the present invention, the work of expanding the sheet body 2 into a face shape is easy and easy to use.
[0014]
Since the lotion 4 is sealed in the inner bag 3, the sheet body 2 can be kept dry until just before use. Therefore, propagation of various bacteria caused by the sheet body 2 being in a wet state for a long time can be effectively prevented, and it can contribute to improvement in cleanliness and safety of the face pack sheet. Since the amount of additives such as preservatives in the lotion 4 can be minimized, the face pack sheet is also excellent in safety in this respect. There is also an advantage that a large amount of perishable materials such as collagen, hyaluron sun, protein, and egg can be added while minimizing the amount of preservatives and the like. In addition, when the sheet body 2 and / or the lotion 4 are sterilized (claim 5), the propagation of various bacteria can be completely suppressed, and the safety of the face pack sheet can be made complete.
[0015]
In particular, when the sheet body 2 is made of a nonwoven fabric, a large amount of oxygen is held between the fibers. Therefore, when left in a wet state, various germs tend to propagate, and it is necessary to mix a lot of preservatives into the lotion. In this regard, in the present invention, since the sheet body 2 can be kept in a dry state until immediately before use, the propagation of various bacteria can be effectively prevented without adding a preservative, and the cleanliness and It can contribute to improving safety.
[0016]
If the seal widths of the joints 6 around the outer periphery of the inner bag 3 are all the same, the opening location when applying a pressing force is difficult to predict, and the opening operation cannot be performed smoothly. In this regard, if the seal width W1 of the left and right joints 6a that are short sides is set to be narrower than the seal width W2 of the front and rear joints 6b that are long sides, the short side joint 6a Since it breaks first, it is easy to predict the opening location, the opening operation can be smoothly performed, and the usability is improved. Also, if the innermost layer of the composite plastic film constituting the inner bag 3 is an easy peel film, the opening operation can be further smoothly performed in this regard.
[0017]
If at least one of the right and left joints 6a serving as the short sides of the inner bag 3 is provided with an easily breakable portion 9 having a small seal width, the joint 6a is separated from the easily breakable portion 9 when external pressure is applied. Since it is peeled off and breaks first, the opening operation can proceed more smoothly.
[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
FIGS. 1 to 3 show a face pack sheet according to the present invention, in which an outer bag 1 contains a dry face pack sheet main body 2 and an inner bag 3 filled with lotion 4. . The outer bag 1 is formed by laminating two left and right horizontally long plastic films facing each other and heat-sealing the four peripheral edges of the two films together to form a rectangular flat bag. The inside thereof is hermetically sealed by the joining portion 5 of FIG. Note that the outer bag 1 can be formed by, for example, bending a square film at the center and joining three peripheral edges facing each other, and the manufacturing method is arbitrary.
[0019]
The plastic film material constituting the outer bag 1 is required to be flexible and impermeable to water, and examples thereof include films of polypropylene, polyethylene, polyethylene terephthalate, and the like. It may be a composite film in which an aluminum foil film is laminated on polypropylene, polyethylene, polyethylene terephthalate, or the like, or may be a vacuum-deposited film.
[0020]
The form of the inner bag 3 is substantially the same as that of the outer bag 1. That is, the inner bag 3 is a rectangular flat bag formed by facing two rectangular plastic films, which are horizontally long in the left and right directions, and heat-sealing and joining the four peripheral edges of each film to each other. The inside is sealed by a joint 6 formed over the entire circumference with water 4 being filled. The seal width W1 of the left and right joints 6a, which are the short sides of the inner bag 3, is set to be narrower than the seal width W2 of the front and rear joints 6b which are the long sides. It is set so as to break first from the joint 6a in the direction.
[0021]
The outer dimensions of the inner bag 3 are set slightly smaller than the outer dimensions of the outer bag 1. When one joint (for example, 6a) is closed after filling the lotion 4 into the inner bag 3, air or an inert gas is injected so that the entire inner bag 3 is slightly inflated.
[0022]
The plastic film material constituting the inner bag 3 is required to be flexible and water-impermeable, and examples thereof include films such as polypropylene, polyethylene, and polyethylene terephthalate. It may be a composite film in which an aluminum foil film is laminated on polypropylene, polyethylene, polyethylene terephthalate, or the like, or may be a vacuum-deposited film.
[0023]
In particular, if at least the innermost layer of the composite plastic film constituting the inner bag 3 is formed of an easy-peel film exhibiting easy-peeling properties, the opening operation of the inner bag 3 can be performed smoothly. The type of the easy peel film may be any of a cohesive peeling type, an interlayer peeling type, and an interface peeling type. Here, the cohesive peeling type refers to a type in which the cohesive force of the seal layer (the strength of the material itself) is too small with respect to the adhesive force with the adjacent layer, and the seal layer itself is broken and peeled. The delamination type refers to a type in which delamination occurs between a sealing layer and an adjacent composite layer. The interfacial peeling type refers to one in which the peel strength is adjusted by adjusting the heat sealing conditions and the like.
[0024]
Examples of the lotion 4 filled in the inner bag 3 include concentrated glycerin 0.5 to 5%, butylene glycol 0.5 to 5%, propylene glycol 0.5 to 5%, and collagen 0.05 to 1%. , Sodium hyaluronate, alpha L-alkorbyl magnesium phosphate 0.02 to 2%, dl-α-tocopherol acetate seaweed extract 0.1 to 3.0%, various plant extracts 0.02 to 2%, dipotassium glycyrrhizinate And 0.05 to 3.0%. Here, it should be noted that no preservative or bactericide is contained, and the amount of alcohol that adversely affects sebum is extremely small. Furthermore, it was possible to contain a large amount of active ingredients, such as collagen, hyaluron sun, protein, and yolk, which could not be put in a large amount because of being easily decayed with conventional face pack sheets and easily deteriorated with an antiseptic. Attention should be paid to the point.
[0025]
The face pack sheet main body 2 is a hydrophilic sheet material which is formed in a substantially facial shape as shown in FIG. 5 and is used by being placed on the face in a wet state impregnated with the lotion 4. Here, as shown in FIG. 2, the inner bag 3 is folded in a flat shape and stored in the outer bag 1 in a state where the inner bag 3 is overlapped on the flat surface. More specifically, the outer dimensions of the sheet body 2 are set to be larger than those of the inner bag 3, and the entire inner bag 3 is substantially displaced into the outer bag 1 in a state of being placed on the upper surface of the sheet body 2. It is stored in close contact.
[0026]
In this embodiment, the face pack sheet main body 2 is stored in the outer bag 1 after being subjected to a sterilization process. Examples of the material of the sheet body 2 include a cotton nonwoven fabric and a rayon nonwoven fabric, a composite nonwoven fabric of cotton and polyethylene, polypropylene, polyethylene terephthalate and the like, a cellulose sponge sheet and the like.
[0027]
When using the face pack sheet, first, the inner bag 3 is opened by pressing the inner bag 3 from the outside by using the flexibility of the inner and outer bags 3.1 to increase the inner pressure. Specifically, as shown in FIG. 4, for example, the inner bag 3 is rolled together with the outer bag 1 from one of the left and right ends, and the inner bag 3 is pressed from the outside over the outer bag 1 with the outer bag 1. The joint 6 on the other end is peeled off. Thus, the inner bag 3 is opened, and the lotion 4 inside is pushed out into the outer bag 1. The lotion 4 supplied into the outer bag 1 impregnates the face pack sheet main body 2 immediately below, so that the sheet main body 2 is in a wet state.
[0028]
Further, by rolling the inner bag 3 together with the outer bag 1, the lotion 4 in the inner bag 3 can be completely squeezed out. Finally, the end portion of the outer bag 1 is cut open with scissors or the like, and the face pack sheet body 2 is taken out of the outer bag 1 and, as shown in FIG. 5, is developed into a facial shape and put on a human body for use. .
[0029]
According to the face pack sheet according to the present embodiment, in a state where the inner bag 3 is stacked on the flat surface of the face pack sheet body 2 folded in a flat shape, the sheet body 2 and the inner bag 3 are connected to the outer bag. Since the toner is taken out of the inner bag 3, the lotion 4 squeezed out from the inner bag 3 is instantaneously impregnated into the sheet body 2 immediately below. Therefore, unlike the form shown in the conventional patent document 1, the problem that the lotion 4 remains in a large amount in the outer bag 1 hardly occurs, and the lotion 4 can be impregnated into the sheet body 2 efficiently without waste. it can.
[0030]
Reducing the amount of various additives such as preservatives is particularly beneficial for those who are allergic to additives or who have skin sensitivity. In addition, a large amount of perishable materials such as collagen, hyaluron sun, and protein, which are suitable for lotion, can be used. There is also an advantage that a large amount of a natural herbal extract humectant can be blended. The amount of alcohol required to dissolve the preservative can also be minimized. If the lotion 4 and the sheet body 2 are sterilized, rot deterioration is small, and this also contributes to improvement in cleanliness and safety.
[0031]
