Description

  The present invention relates to a skin pack package in which an object to be packaged is held between a skin pack film and a mount.

The skin pack packaging body covers the package attached to the surface of the cardboard mount, covers the skin pack film, sucks it to stretch the skin pack film, and adheres the skin pack film to the surface of the mount (Patent Document 1).
If a skin pack film is used, an article to be packaged can be packaged in a compact and inexpensive manner.

However, since the skin pack film is a film that is easy to stretch and difficult to cut, the skin pack package cannot be easily opened by hand.
Specifically, when the skin pack package is opened by hand without using a cutting tool such as scissors, it will stretch even if the skin pack film is pulled. Therefore, the film is easily peeled off from the mount. I wo n’t. When pulled further, the cardboard itself, which is the mount, breaks in the surface direction and is separated into two mount pieces (hereinafter referred to as the front half mount piece and the back half mount piece), and the front half mount piece is the skin. Only the back half backing piece is removed while still adhered to the back of the pack film. In this state, since the front half mount piece is still attached to the back surface of the skin pack film, the package cannot be taken out unless the front half mount piece is removed from the skin pack film.
As described above, in the conventional skin pack package, it is very troublesome to take out the packaged item, and the improvement is required.

Japanese Utility Model Publication No. 62-76165

  An object of the present invention is to provide a skin pack package capable of easily taking out an object to be packaged.

The present invention includes a backing sheet, an article to be packaged, and a skin pack film, a bonding portion where the skin pack film and the backing sheet are bonded, and the skin pack film and the mounting sheet are not bonded. In the skin pack package in which the package is held between the mount and the skin pack film, the mount includes a first layer, at least a first strength, and a second strength. A second layer bonded to the surface of the first layer with two types of adhesive strength, and the first strength can be delaminated between the first layer and the second layer. An adhesive strength for adhering the layers, wherein the second strength is greater than the first strength, and the first layer and the second layer are bonded at the first strength in a region corresponding to the adhesive portion. Corresponding to the non-bonded part. In the region, the first layer and the second layer have a region bonded with the second strength, and a part or all of an edge of the region bonded with the second strength is the first strength. Adjacent to the bonded region, and the adjacent part exists in the region corresponding to the non-bonded portion, and in the region corresponding to the non-bonded portion and the region bonded with the first strength. The second layer has a portion where the breaking strength is smaller than the second strength.
In the present invention, “mount” is a member that holds the package in cooperation with the skin pack, and “paper” on the mount has a limited meaning that “the mount is made of paper”. Note that this is not the case.

Since the skin pack package of the present invention has a region where the first layer and the second layer are bonded with the first strength in the region corresponding to the bonding portion, the second layer is opened when the skin pack package is opened. The first layer and the second layer are delaminated while being adhered to the skin pack film.
Further, a part or all of the edge of the region bonded with the second strength is adjacent to the region bonded with the first strength, and the adjacent portion exists in the region corresponding to the non-bonded portion. Since the fracture strength of the second layer is smaller than the second strength in the region corresponding to the non-bonded portion and in the region bonded with the first strength, the peeling point is in the region corresponding to the non-bonded portion. , The second layer breaks in the thickness direction and divides.
Accordingly, the mount is removed from the non-adhesive portion of the skin pack film, which is the storage portion for the packaged object, and the packaged object can be easily removed therefrom.

In a preferred skin pack package of the present invention, the adhesive strength between the skin pack film and the second layer is greater than the first strength in the adhesive portion.
In a preferred skin pack package of the present invention, a defect portion is formed in the surface of the second layer corresponding to the non-adhesion portion, and the defect portion is located in a region corresponding to the non-adhesion portion and the first layer. It is formed in a region bonded with one strength.

  The skin pack package of the present invention can easily separate the mount and the skin pack film, and can easily take out the packaged article stored in the non-adhesive portion of the skin pack film.

[First Embodiment]
In the skin pack package according to this embodiment, the second layer of the mount is composed of a relatively fragile layer.
In FIG. 1 to FIG. 5, the skin pack package 1 includes a mount 2, a package 3, and a skin pack film 4 that holds the package 3 in cooperation with the mount 2.
The skin pack film 4 has a portion that covers the package 3 and is not adhered to the mount 2, and a portion that does not cover the package 3 and adheres to the mount 2.
Hereinafter, a portion where the skin pack film 4 and the mount 2 are not bonded is referred to as a non-bonded portion 4n, and a portion where the skin pack film 4 and the mount 2 are bonded is referred to as a bonded portion 4p.
In FIG. 1, in order to make it easy to understand the range in which the bonding portion 4p and the non-bonding portion 4n are provided, the bonding portion is indicated by shading for convenience.

Specifically, the back surface of the skin pack film 4 is substantially in close contact with the article to be packaged 3 at the part where the article to be packaged 3 is interposed, and is not adhered to the mount 2 at that part. It adheres to the mount 2 at the part where the object 3 does not intervene. However, due to the nature of the skin pack film 4, the skin pack film 4 is not in close contact with the entire package 3, but faces the mount 2 (although it is influenced by the shape of the package 3). It adheres substantially along the outer shape of the article to be packaged 3 excluding the part that is covered.
Note that in this specification, the close contact refers to a state of contact but not adhesion.

The bonding portion 4p where the skin pack film 4 and the mount 2 are bonded is an annular region in the front view that exists around the package 3. Specifically, as shown in FIG. 1, the bonding portion 4 p is an end portion (right side) of the skin pack film 4 (or mount 2) that extends in a vertical strip shape on each of the right side and the left side with respect to the package 3. End portion and left end portion), and end portions (upper end portion and lower end portion) of the skin pack film 4 (or mount 2) extending in the left-right direction on each of the upper and lower sides.
The non-adhesive part 4n where the skin pack film 4 and the mount 2 are not adhered is an area excluding the adhesive part 4p.

  However, in order to form the unsealing start part 11, as shown in FIG. 5, it is not adhere | attached between the one edge part of the skin pack film 4, and the one edge part of the base_sheet | mounting_paper 2. As shown in FIG. For example, the back surface of one edge portion of the right end portion of the skin pack film 4 facing one corner of the mount 2 is not bonded to the surface of the mount 2 and has a slight gap with the surface of the mount 2. Is in close contact with it. One corner of the mount 2 facing one edge of the skin pack film 4 corresponds to the opening start point 11.

  The skin pack package 1 in the illustrated example is the one in which the package 3 is sealed and packaged with the skin pack film 4 and the mount 2 without gaps. The skin pack package 1 of the present invention is the package in which the package 3 is sealed. However, the present invention is not limited to this mode, and any material that can hold the package 3 by the cooperation of the skin pack film 4 and the mount 2 may be used.

  For example, the skin pack package 1 of the present invention has a skin so that the bonding portion 4p is not annular and a part of the package 3 is exposed from one end of the skin pack film 4 or two opposite ends. The pack film 4 may be adhered (not shown). However, also in this case, the skin pack film 4 needs to be covered and bonded by the bonding portion 4p so that the package 3 cannot be taken out from the exposed portion of the package 3.

The package 3 is not particularly limited, and examples thereof include various products such as cosmetics and stationery.
The shape of the article 3 is not particularly limited. Further, the package 3 may be disposed near the top, bottom, left, or right of the mount 2 in addition to the substantially central portion of the mount 2.
As the skin pack film 4, a conventionally known film can be used on condition that the skin pack film 4 is a film that can be firmly adhered to the surface of the mount 2 (the surface of the second layer 22). Examples of the material of the skin pack film 4 include thermoplastic resins such as ethylene-vinyl acetate copolymer, soft vinyl chloride, polyolefin such as polyethylene. As the skin pack film 4, a transparent film is usually used. The film includes what is generally called a sheet.
The thickness of the skin pack film 4 is not specifically limited, For example, 30 micrometers-200 micrometers, Preferably, they are 60 micrometers-150 micrometers.
The breaking strength of the skin pack film 4 is sufficiently large and is larger than the breaking strength of the first layer 21 of the mount 2 described later.

The mount 2 is composed of a laminate of at least two layers of a first layer 21 and a second layer 22.
The first layer 21 and the second layer 22 are bonded with at least two types of adhesive strengths of a first strength and a second strength. That is, the surface of the first layer 21 and the back surface of the second layer 22 are bonded, but the second layer 22 is bonded to the region A1 bonded at the first strength (hereinafter referred to as the first strength bonded region), A region A2 (hereinafter referred to as a second strength adhesive region) bonded with the second strength in a region other than the first strength region is bonded to the first layer 21.
In FIG. 1, in order to make the first strength adhesion region A1 and the second strength adhesion region A2 easy to understand, for convenience, a range where the first layer and the second layer are adhered in the second strength adhesion region is indicated by light ink painting. .

The first strength is an adhesive strength that allows the first layer 21 and the second layer 22 to be delaminated, and the second strength is greater than the first strength.
Here, the adhesive strength (first strength) that can delaminate the first layer and the second layer is that a separate support film (polyethylene terephthalate film having a thickness of 30 μm) is firmly attached to the surface of the second layer. When the support film is peeled off by hand, the second layer does not break down the material, and the second layer is peeled off from the first layer together with the support film.

Hereinafter, the mount 2 will be described in detail.
The front view shape of the mount 2 is a substantially rectangular shape. However, the mount 2 may be formed in a substantially circular shape, a substantially elliptical shape, a substantially triangular shape, a substantially trapezoidal shape, or the like when viewed from the front (not shown).
The front view shapes of the first layer 21 and the second layer 22 constituting the mount 2 are preferably substantially the same shape and size. However, the second layer 22 and the first layer 21 are not limited to the same shape and size, and the second layer 22 may be slightly smaller than the first layer 21.
In addition, when the mount 2 has a third layer in addition to the first layer 21 and the second layer 22 (when the mount 2 is composed of a laminate of three or more layers), for example, the third layer is the first layer. It is firmly bonded to the back surface of 21 (not shown).

  The material for forming the first layer 21 is not particularly limited, and a single-layer sheet such as cardboard, plain paper, coated paper, non-woven fabric, synthetic paper, synthetic resin sheet, and foamed resin sheet, and these two or more sheets are laminated and bonded. Various sheet materials such as laminated sheets can be used. The sheet includes what is generally called a film.

  The material of the synthetic resin sheet or the foamed resin sheet is not particularly limited, and examples thereof include polyolefins such as polyethylene and polypropylene, polyesters such as polyethylene terephthalate, and polyamides such as nylon. Especially, when the 1st layer 21 contains synthetic resins, such as a synthetic resin sheet, since the material is comparatively excellent in strength, a polyester system is preferred and polyethylene terephthalate is more preferred.

In the present embodiment in which the relatively fragile second layer 22 is used, the waist strength of the mount 2 mainly depends on the first layer 21, so the first layer 21 is compared to the second layer 22. A material having a high breaking strength is used.
The magnitude of the breaking strength is affected by the material and the layer shape, but generally the thickness of the forming material is greatly affected.
When the first layer 21 is formed of synthetic paper or a synthetic resin sheet, the thickness of the first layer 21 is, for example, about 8 μm to 200 μm, and preferably 10 μm to 100 μm. When the 1st layer 21 is formed with the foaming resin sheet, the thickness of the 1st layer 21 is about 50 micrometers-300 micrometers, for example, Preferably, it is 50 micrometers-200 micrometers. If the first layer 21 is formed of paper or nonwoven fabric such as plain paper or coated paper, its weight per unit area is, for ^example, 20g / ^{m 2} ~500g / m 2, preferably about, 30 g ^{/ m} 2 ~ 300 g / m ² .

  The material for forming the second layer 22 is not particularly limited. However, since the second layer 22 is relatively fragile in this embodiment, the material for forming the second layer 22 is a synthetic resin coating film or a very thin synthetic resin sheet. And very thin synthetic paper. The material of the synthetic resin is not particularly limited, and examples thereof include polyolefins such as polyethylene and polypropylene, and polyesters such as polyethylene terephthalate. Especially, since the material of the 2nd layer 22 is excellent in adhesiveness with the skin pack film 4, polyolefin type is preferable and also polyethylene type is more preferable.

For example, the breaking strength of the relatively fragile second layer 22 is preferably 0.3N to 2.0N, and more preferably 0.5N to 1.5N. When the breaking strength of the second layer 22 is less than 0.3 N, the handleability of the mount 2 is deteriorated. If the breaking strength of the second layer 22 exceeds 2.0 N, the second layer 22 may not break at the non-adhesive portion 4n when the skin pack package is opened.
Further, the breaking strength of the first layer 21 is larger than the breaking strength of the second layer 22, and more preferably larger than the second strength. The adhesive strength of the first layer 21 is, for example, 40 N or more. If the breaking strength of the first layer 21 is less than the above, the first layer 21 may be broken when the skin pack package 1 is opened.

  According to JIS Z 0237, the breaking strength is prepared as a single-layer or second-layer test piece (length: 100 mm × width: 15 mm) to be measured, and both ends of the test piece are chucked with a measuring device. It is measured by gripping and pulling the test piece in the longitudinal direction at a speed of 200 mm / min under the condition where the temperature is 23 ° C.

As described above, the breaking strength of each layer is influenced by the material and the layer shape, but generally the thickness of the forming material greatly affects.
Examples of the second layer 22 having the breaking strength include a synthetic resin coating film, a synthetic resin sheet, or synthetic paper having a thickness of 5 μm to 40 μm, preferably 5 μm to 20 μm.

  The surface of the second layer 22 constitutes the surface of the mount 2. An adhesive layer (not shown) for adhering the skin pack film 4 is provided on the surface of the second layer 22 (the surface of the mount 2). Although the thickness of an adhesive bond layer is not specifically limited, For example, they are 10 micrometers-20 micrometers. Examples of this adhesive include a heat-sensitive adhesive. However, when the second layer 22 itself is made of a material that can be adhered to the skin pack film 4, or when an adhesive layer is provided on the back surface of the skin pack film 4, the surface of the second layer 22 is It is not necessary to provide an adhesive layer.

  One example of the skin pack film 4 and the mount 2 is summarized in Table 1. However, the skin pack package 1 of the present invention is not limited to the configuration shown in Table 1.

In addition, a desired design may be represented on the surface or back surface of the first layer 21 or / and the surface of the second layer 22 as necessary.
When the first layer 21 and the second layer 22 are both transparent, the design may be printed on the back surface of the first layer 21 so that the design display can be seen from the front side of the mount 2 in the correct orientation.

The second layer 22 and the first layer 21 have a first strength adhesive region A1 and a second strength adhesive region A2 in a range where the first strength adhesive region A1 is not provided. .
In the region corresponding to the bonding portion 4p, the first strength bonding region A1 (the region where the first layer 21 and the second layer 22 are bonded with the first strength) is included, and in the region corresponding to the non-bonding portion 4n, It has said 2nd intensity | strength adhesion area | region A2 (area | region where 1st layer 21 and 2nd layer 22 were adhere | attached by 2nd intensity | strength).

  For example, the first layer 21 and the second layer 22 are bonded with the first strength in all or a part of the region corresponding to the bonding portion 4p, and the first layer 21 and the second layer are bonded in the other regions. 22 is bonded with the second strength. Alternatively, the interlayer between the first layer 21 and at least one end of the second layer 22 corresponding to the bonded portion 4p is bonded with the first strength, while the second layer 22 corresponding to the non-bonded portion 4n. The first layer 21 and the first layer 21 are bonded with a second strength.

  In the case of the illustrated example, the right end, upper end, and lower end (three ends of the second layer 22) of the second layer 22 corresponding to the bonding portion 4p and the first layer 21 facing them. Are bonded with the first strength and other layers (the second layer 22 corresponding to the non-bonded portion 4n and the first layer 21 facing the second layer 22 and the first layer corresponding to the bonded portion 4p). The left end of the two layers 22 and the first layer 21 facing the two layers 22 are bonded with a second strength. Accordingly, one of the four ends of the second layer 22 (the left end in the illustrated example) corresponds to the bonding portion 4p, but is bonded to the first layer 21 with the second strength. ing.

  Note that the right end of the second layer 22 corresponding to the bonding portion 4p, the right end of the upper end, the right end of the lower end, and the first layer 21 facing them are bonded with a first strength. And other layers (the layer between the second layer 22 corresponding to the non-bonded portion 4n and the first layer 21 facing it, and the left end and upper end of the second layer 22 corresponding to the bonded portion 4p) The left side portion and the left side portion of the lower end portion and the first layer 21 facing the left side portion may be bonded with a second strength (not shown).

  The interlayer between the first layer 21 and the second layer 22 may have a portion bonded with an adhesive strength other than the first strength and the second strength (hereinafter referred to as the third strength). For example, the right end portion, the upper end portion and the lower end portion of the second layer 22 corresponding to the bonding portion 4p and the first layer 21 facing them are bonded with the first strength and correspond to the non-bonding portion 4n. The interlayer between the second layer 22 and the first layer 21 facing the second layer 22 is bonded with the second strength, and the left end portion of the second layer 22 corresponding to the bonding portion 4p and the interlayer between the first layer 21 facing the second layer 22 are bonded. Further, it may be bonded with a third strength (not shown). The third strength is not particularly limited, but is preferably larger than the first strength and smaller than the second strength, or larger than the second strength.

Further, a part of the edge A2a of the second strength adhesion region A2 is located inside the inner edges 4pa, 4pb, 4pc of the adhesion part 4p at the right end, upper end, and lower end. Accordingly, a part of the edge A2a of the second strength bonding area A2 exists in the area corresponding to the non-bonding portion 4n (in other words, the second strength bonding area A2 has an edge serving as the edge of the mount 2). The edge of the excluded region A2 is provided so as to be included in the range surrounded by the inner edge of the bonding portion 4p).
Preferably, a part of the edge A2a of the second strength adhesion region A2 is coincident with or located in the vicinity of at least one inner edge of each of the inner edges of the right end portion, the upper end portion, and the lower end portion of the bonding portion 4p. More preferably, as shown in the drawing, all three inner edges 4pa, 4pb, 4pc of the bonding portion 4p on the right end, upper end, and lower end coincide with each other or are located in the vicinity of each inner edge.

  In addition, a part of the edge A2a of the second strength bonding region A2 existing in the region corresponding to the non-bonding portion 4n is adjacent to the edge of the first strength bonding region A1. For this reason, this adjacent part (boundary part of 2nd strength adhesion field A2 and 1st strength adhesion field A1) exists in the field corresponding to non-adhesion part 4n.

  The second strength is not particularly limited as long as it is greater than the first strength and the breaking strength of the second layer 22 corresponding to the non-bonded portion 4n. Further, the second strength may be the same as the adhesive strength between the back surface of the skin pack film 4 and the surface of the second layer 22 in the bonding portion 4p, or may be larger or smaller than that. Also good.

The first strength is, for example, 0.45N to 25N, preferably 1.0N to 20N, and more preferably 2.0N to 10N. If the first strength is too small, the first layer 21 and the second layer 22 may be inadvertently peeled from the end portions. On the other hand, if the first strength is too large, the skin pack package 1 is opened. There is a possibility that the first layer 21 and the second layer 22 cannot be delaminated from the end portions.
The second strength is, for example, more than 25N, preferably 26N to 40N.

When the first strength is 0.45N to 5.0N, the first layer 21 and the second layer 22 are bonded by pseudo bonding at the bonding portion 4p. When the first strength is 3.0N to 25N, the first layer 21 and the second layer 22 are bonded by weak bonding at the bonding portion 4p.
The pseudo-adhesion refers to a state where the adhesion is weak enough to allow delamination with a slight force. The weak adhesion refers to a state where the adhesion is stronger than the pseudo-adhesion but is weak enough to allow easy delamination.

  However, the adhesive strength is in accordance with JIS Z 0237 by using a separate support film (polyethylene terephthalate film with a thickness of 30 μm) on the surface of the second layer of the laminate of the first layer and the second layer and using an adhesive. A test piece affixed to is prepared and measured in a peel test under the conditions of a length of 100 mm × width of 15 mm, a peel angle of 180 degrees, a peel speed of 300 mm / min, and a temperature of 23 ° C.

Although the manufacturing method of the base_sheet | mounting_paper 2 which has the 1st layer 21 and the 2nd layer 22 which were adhere | attached by said 1st strength adhesion area | region A1 and 2nd strength adhesion area | region A2 is not specifically limited, For example, the following method is mentioned.
An adhesive anchor coat agent is applied to a region corresponding to the second strength adhesion region A2 in the surface of the first layer 21, and a synthetic resin heated and melted is applied onto the first layer 21 to form a coating film. And the coating is cured. According to this method (thermal lamination method), the cured coating film becomes the second layer 22, and the back surface of the second layer 22 is the second layer 22 in the region where the adhesive anchor coat layer is provided. In the region where the adhesive anchor coat layer is not provided (the region where the surface of the first layer 21 is exposed), the back surface of the second layer 22 is bonded to the first layer 21 with the first strength. In this case, the first layer 21 and the second layer 22 in the first strength bonding region A1 are bonded by the pseudo bonding.

  Further, a masking agent (ultraviolet curable ink) is applied to the surface of the first layer 21 and further reduces the adhesive strength of the pressure-sensitive adhesive on the surface of the pressure-sensitive adhesive layer corresponding to the first strength adhesion region A1. Etc.) and the second layer 22 is laminated on the first layer 21. According to this method, in the region where the masking layer is provided, the back surface of the second layer 22 is bonded to the first layer 21 with the first strength, and the region where the masking layer is not provided (the surface of the adhesive layer is exposed). The back surface of the second layer 22 is bonded to the first layer 21 with the second strength. In this case, the first layer 21 and the second layer 22 in the first strength adhesion region A1 are bonded by the weak adhesion.

The mount 2 in the illustrated example is manufactured by the thermal lamination method, and this mount 2 uses a synthetic resin sheet as the first layer 21, and the second strength adhesion region A <b> 2 of the surface of the first layer 21. The adhesive anchor coat layer 24 is provided in a region corresponding to the above, and the second layer 22 made of a synthetic resin film is bonded to the exposed surface of the first layer 21 and the surface of the adhesive anchor coat layer 24. .
In the case of the thermal lamination method, the synthetic resin constituting the first layer 21 and the second layer 22 can be selected as appropriate. However, as described above, the first layer 21 is preferably a polyester resin, and the second layer 22 is Polyolefins are preferred because they are easy to pseudo-adhere.

In the skin pack package 1 of the present invention, the adhesive strength between the skin pack film 4 and the second layer 22 in the adhesive portion 4p is greater than the first strength.
As described above, the portion of the skin pack film 4 that is not covered with the package 3 is bonded to the surface of the second layer 22 via the adhesive layer or directly. Therefore, the back surface of the skin pack film 4 is firmly bonded to the surface of the second layer 22 in the bonding portion 4p.
The adhesive strength between the skin pack film 4 and the second layer 22 in the adhesive portion 4p is, for example, 30N or more, preferably 35N or more.

  However, the adhesive strength between the skin pack film and the second layer at the bonded portion is in accordance with JIS Z 0237, and the back surface of the second layer is firmly formed on a separate support film (polyethylene terephthalate film having a thickness of 30 μm). A test piece was prepared by adhering and having a skin pack film adhered to the surface of the second layer. The test piece was 100 mm long × 15 mm wide, the peel angle was 180 degrees, the peel speed was 300 mm / min, and the temperature was 23. Measured in a peel test under the condition of ° C.

On the other hand, at least one end of the second layer 22 and the first layer 21 in the region corresponding to the bonding portion 4p are bonded with a first strength (adhesive strength that allows delamination), As described above, the first intensity is, for example, 0.45N to 25N.
The difference between the adhesive strength between the skin pack film 4 and the second layer 22 and the first strength at the adhesive portion 4p (adhesive strength between the skin pack film 4 and the second layer 22-the first strength) is, for example, , 5.0N or more, preferably 7.0N or more, more preferably 15N or more. If the difference is 5N or more, when the first layer 21 is peeled off, the skin pack film 4 and the second layer 22 in the bonding portion 4p remain adhered, and the first layer 21 is securely removed from the second layer 22. Can be peeled off.

Further, the breaking strength of the second layer 22 corresponding to the non-bonded portion 4n is smaller than the second strength. That is, the breaking strength of the second layer 22 is smaller than the second strength in the region corresponding to the non-bonded portion 4n and the region bonded with the first strength.
The material and thickness of the second layer 22 of the present embodiment are substantially uniform over the entire surface direction. Therefore, the breaking strength of the second layer 22 is smaller than the second strength in the region corresponding to the non-bonded portion 4n and in the region bonded with the first strength, and the second layer 22 is broken. As described above, the strength is, for example, 0.3N to 2.0N.

The difference between the second strength and the breaking strength of the second layer 22 corresponding to the non-bonded portion 4n (second strength−breaking strength of the second layer 22) is, for example, more than zero, and preferably is 0.2. 15N or more, more preferably 1.0N or more. If the difference is 0.15 N or more, the second layer 22 can be divided in the thickness direction along the adjacent portion at the time of opening.
Table 2 summarizes the schematic relationship such as the adhesive strength between the skin pack film 4 and each layer of the mount 2.

The skin pack package 1 can be manufactured, for example, as follows.
The package 3 is attached to the surface of the mount 2 to which the first layer 21 and the second layer 22 are bonded with the first strength bonding area A1 and the second strength bonding area A2. For example, the article to be packaged 3 is arranged at substantially the center of the surface of the mount 2.
Then, the skin pack film 4 that has been softened by heating is covered from above the article 3 and the skin pack film 4 is brought into close contact with the mount 2 side.

  For example, compressed air is applied from the surface side of the softened skin pack film 4 so that the skin pack film 4 adheres along the package 3 and the skin pack is exposed on the surface of the mount 2 exposed around the package 3. The back surface of the film 4 is brought into close contact. Alternatively, the air between the mount 2 and the skin pack film 4 is sucked in the softened skin pack film 4 in a vacuum atmosphere. In the case of this vacuum suction, air between the front surface of the mount 2 and the back surface of the skin pack film 4 passes through the mount 2 from the front surface of the mount 2 and is sucked to the back surface side of the mount 2. When the mount 2 is not air permeable in the thickness direction (for example, as described above, when the first layer 21 is made of a synthetic resin sheet, the surface of the mount 2 does not have air permeability in the thickness direction of the mount 2). It is preferable that a plurality of small air holes (for example, air holes having a diameter of 0.05 mm to 0.2 mm) penetrating from the back surface to the back surface are provided at predetermined intervals on the top, bottom, left and right sides of the mount 2. By using such a mount 2 having air permeability, the skin pack film 4 can be sucked to the mount 2 by vacuum suction.

  Further, when the skin pack film 4 is covered with a thin plate applied to the surface of one corner portion of the mount 2, the skin pack film 4 does not adhere to the surface of the corner portion of the mount 2, and the thin plate is pulled out. An opening start point portion 11 in which one edge portion of the skin pack film 4 is not adhered to the mount 2 can be formed. The thin plate is a thin plate having a thickness of several tens of μm to several mm and does not adhere to either the front surface of the mount 2 or the back surface of the skin pack film 4.

By the compressed air or vacuum suction, the skin pack film 4 expands and adheres to the article 3 to be packaged, and the skin pack film 4 adheres to the surface of the mount 2 on which the article 3 to be packaged does not exist.
In this way, the skin pack package 1 is obtained.
If necessary, unnecessary portions around the skin pack package 1 may be cut off to adjust the outer shape of the skin pack package 1, or a hole for suspension may be formed.

When opening the skin pack packaging body 1 of the present invention, for example, the opening starting point portion 11 which is one edge portion of the first layer 21 of the mount 2 is picked and pulled up in a direction away from the skin pack film 4.
In the adhesive portion 4p adjacent to the opening start point portion 11, the end portion of the second layer 22 adhered to both the skin pack film 4 and the first layer 21 is adhered to the skin pack film 4 more strongly than the first layer 21. 6 (since the second layer 22 and the first layer 21 are bonded to each other at the first strength in the region corresponding to the bonding portion 4p), as shown in FIG. The first layer 21 is delaminated from the second layer 22 while the layer 22 remains adhered to the skin pack film 4. In addition, even if it is except opening opening part 11, even if the edge part (right side edge part, upper end part, or lower end part) adhere | attached with 1st intensity | strength is picked up and pulled up, 1st layer 21 is peeled similarly it can. Alternatively, the edge of the skin pack film 4 may be picked and peeled off (either the edge of the first layer 21 or the edge of the skin pack film 4 can be picked similarly).

  The peeling point advances by further peeling, but the peeling point is the edge A2a of the second strength bonding region A2 in the non-bonding portion 4n (the adjacent portion between the first strength bonding region A1 and the second strength bonding region A2). ), The second layer 22 is divided in the thickness direction as shown in FIG.

The reason why the second layer 22 is divided in the thickness direction is as follows.
That is, once the first layer 21 and the second layer 22 are delaminated at the beginning of opening, the first layer 21 and the second layer 22 can be delaminated with a slight force thereafter (the delamination point is the first layer 21). And the second layer 22 is concentrated on one point). Therefore, even if the breaking strength of the second layer 22 is smaller than the first strength in the region corresponding to the non-bonded portion 4n and in the region bonded with the first strength (first strength bonding region A1), it is adjacent. Until reaching the site, the second layer 22 does not break, and the two layers delaminate between the first layer 21 and the second layer 22.

  When the peeling point advances to the adjacent portion, the first layer 21 and the second layer 22 bonded with the second strength are difficult to delaminate, so that the first layer 21 and the second layer 22 are strongly pulled. Power is added. As described above, the breaking strength of the first layer 21 is larger than the breaking strength of the second layer 22, and the breaking strength of the second layer 22 is smaller than the second strength. Therefore, when the peeling point reaches the adjacent portion, the peeling does not proceed beyond the adjacent portion, and within the region corresponding to the non-bonded portion 4n and bonded with the first strength (first strength bonding region A1). ), The second layer 22 is broken.

Therefore, after the adjacent portion, the second layer 22 bonded with the second strength follows the first layer 21 while adhering to the surface of the first layer 21, so that the non-adhesive portion 4 n which is a storage portion of the article 3 to be packaged. The mount 2 is removed from the opening 12 to open, and the article 3 can be easily removed therefrom.
In addition, before the said peeling point reaches an adjacent site | part, the 2nd layer 22 in the area | region corresponding to the non-bonding part 4n may break, but even in that case, the 2nd layer 22 after the fracture | rupture is Since it follows, adhere | attaching on the 1st layer 21, the base_sheet | mounting_paper 2 is removed from the non-adhesion part 4n, and it opens.

In particular, a part of the edge A2a (that is, the adjacent portion) of the second strength adhesion region A2 coincides with or is located in the vicinity of all or at least one of the inner edges of the bonding portion 4p. In this case, the second layer 22 hardly remains in the region corresponding to the non-adhesive portion 4n, and the mount 2 can be removed from the entire non-adhesive portion 4n and opened there.
As described above, the skin pack package 1 of the present invention can remove the second layer 22, which is a part of the mount 2, from the non-adhesive portion 4 n by peeling between the first layer 21 and the skin pack film 4. The package 3 can be easily taken out from the opening.

  The skin pack package 1 has a part of the edge A2a of the second strength adhesion area A2 of the mount 2 in the area corresponding to the non-adhesion portion 4n, but the edge A2a of the second strength adhesion area A2 Even if the second strength adhesion region A2 is provided so that all (all the adjacent portions of the first strength adhesion region A1 and the second strength adhesion region A2) are located in the region corresponding to the non-adhesion portion 4n. Good.

For example, as shown in FIGS. 8 and 9, the entire second strength adhesion region A2 may be provided within the range of the second layer 22 corresponding to the non-adhesion portion 4n. In this case, all of the edge A2a of the second strength adhesion region A2 (all of the adjacent portions) are located in a region corresponding to the non-bonding portion 4n (preferably, the edge A2a of the second strength adhesion region A2). All of the inner edges 4pa, 4pb, 4pc, 4pd of the bonding part 4p or all of the inner edges 4pa, 4pb, 4pc, 4pd, or the vicinity of the inner edge) The end of the first layer 21 and the first layer 21 are bonded with a first strength.
In FIG. 8, for the same reason as in FIG. 1, the adhesion portion is represented by shading, and the range where the first layer and the second layer are adhered in the second strength adhesion region is represented by light ink painting.

  Since all the edges of the second strength bonding area A2 are located in the area corresponding to the non-bonding part 4n, the second strength bonding area A2 is peeled off from any edge around the first layer 21 (or the skin pack film 4). In addition, the first layer 21 can be peeled off from the second layer 22 in the bonded portion 4p, and the non-bonded portion 4n can be opened.

Further, the second strength adhesive region A2 is not limited to one, and may be provided in a plurality of dispersed regions.
For example, in the skin pack package 1 shown in FIG. 10, a plurality of second strength adhesion regions A2 between the first layer 21 and the second layer 22 are provided at intervals in a region corresponding to the non-adhesion portion 4n. It has been. Preferably, the plurality of second strength adhesion regions A2 are provided at at least four corners of the region corresponding to the non-adhesion portion 4n.
The layers between the first layer 21 and the second layer 22 other than the second strength adhesion region A2 are bonded with the first strength.
In FIG. 10, for the same reason as in FIG. 1, the adhesion portion is represented by shading, and the range where the first layer and the second layer are adhered in the second strength adhesion region is represented by light ink painting.

  In FIG. 10, all of the plurality of second strength adhesion regions A2 are illustrated as being provided in the region corresponding to the non-adhesion portion 4n. However, some or all of the second strength adhesion regions A2 are included. , It may partially extend to the region corresponding to the bonding portion 4p.

[Second Embodiment]
In the skin pack package according to the second embodiment, a defect portion is provided in the second layer of the mount. Hereinafter, although 2nd Embodiment is described, about the structure and effect similar to the said 1st Embodiment (it considers that it demonstrated), the description is abbreviate | omitted and a term and a code | symbol may be used.

In FIG. 11 and FIG. 12, the skin pack package 1 includes a mount 2, a package 3, and a skin pack film 4 that holds the package 3 in cooperation with the mount 2.
As in the first embodiment, the skin pack package 1 has a non-adhesive portion 4n and an adhesive portion 4p, and the mount 2 is formed by attaching the first layer 21 and the first layer 21 bonded with the first strength and the second strength. The back surface of the skin pack film 4 is bonded to the surface of the second layer 22 at the bonding portion 4p.

The first strength is an adhesive strength for bonding both layers so that the first layer 21 and the second layer 22 can be delaminated, and the second strength is greater than the first strength.
In the region corresponding to the bonding portion 4p, the first strength bonding region A1 (the region where the first layer 21 and the second layer 22 are bonded with the first strength) is included, and in the region corresponding to the non-bonding portion 4n, It has said 2nd intensity | strength adhesion area | region A2 (area | region where 1st layer 21 and 2nd layer 22 were adhere | attached by 2nd intensity | strength).
Moreover, the adjacent site | part of 2nd intensity | strength adhesion area | region A2 and 1st intensity | strength adhesion area | region A1 exists in the area | region corresponding to the non-bonding part 4n. The second layer 22 in the adjacent portion or the vicinity thereof has a portion whose breaking strength is smaller than the second strength.

However, in the present embodiment, the right end of the second layer 22 corresponding to the bonded portion 4p, the right half of the upper end and the right half of the lower end, and the right half of the second layer 22 corresponding to the non-bonded portion 4n and those The first layer 21 facing the first layer 21 is bonded with a first strength, and the other layers (the left half of the second layer 22 corresponding to the non-bonded portion 4n and the first layer 21 facing it) The interlayer and the left end of the second layer 22 corresponding to the bonding part 4p, the left half of the upper end and the left half of the lower end and the interlayer of the first layer 21 facing them) are bonded with the second strength. ing.
In FIG. 11, for the same reason as in FIG. 1, the adhesion portion is represented by shading, and the range where the first layer and the second layer are adhered in the second strength adhesion region is represented by light ink.

The second layer 22 of the present embodiment itself has a higher breaking strength than the second layer of the first embodiment.
Specifically, the material and thickness of the second layer 22 are substantially uniform over the entire surface direction, but the thickness is larger than that of the second layer 22 of the first embodiment. The two layers 22 have a higher breaking strength than the second layer of the first embodiment.
The breaking strength of the second layer 22 itself is greater than or substantially the same as the second strength. For example, the breaking strength of the second layer 22 is 25N to 35N.

In the present embodiment, the breaking strength of the second layer 22 itself is greater than the second strength. However, a defective portion is provided in a part of the surface of the second layer 22 in at least the region corresponding to the non-bonded portion 4n and bonded in the first strength (first strength bonded region A1). As a result, the breaking strength of the second layer 22 is weakened at that portion.
That is, the breaking strength of the second layer 22 corresponding to the non-bonded portion 4n in the portion where the defect portion is provided is smaller than the second strength. For example, the breaking strength of the second layer 22 in the portion where the defect portion is provided is, for example, 0.3N to 2.0N.
The breaking strength of the second layer 22 provided with the defect portion is the same as the method for measuring the breaking strength of the second layer of the first embodiment except that the second layer provided with the defect portion is used as a test piece. Can be measured.

As a defect | deletion part, as shown also in FIG. 13, the perforation line 6 provided in the surface of the 2nd layer 22 is mentioned, for example. In FIG. 13, for easy understanding, the range where the first layer and the second layer are bonded in the second strength bonding region is indicated by light ink painting, and the first layer and the second layer are bonded in the first strength bonding region. The displayed range is shown in plain color.
The perforation line 6 is provided in a region of the second layer 22 corresponding to at least the non-bonding portion 4n.
In the illustrated example, the perforation line 6 extends in the vertical direction from the upper edge to the lower edge of the second layer 22. Accordingly, the perforation line 6 (defect portion) is formed not only in the region corresponding to the non-bonded portion 4n but also in the region corresponding to the bonded portion 4p. In the bonded portion 4p, the second layer 22 and the skin pack are formed. Since the film 4 is firmly bonded, even if a defect portion is provided in the second layer 22 corresponding to the bonding portion 4p, there is no problem in implementing the present invention.

A perforation line 6 (missing portion) in the surface of the second layer 22 corresponding to the non-bonding portion 4n is along the adjacent portion of the first strength bonding region A1 and the second strength bonding region A2 within the range of the non-bonding portion 4n. Or in the vicinity of the part.
Specifically, the perforation line 6 (defect portion) coincides with the edge of the second strength adhesion region A2 at least within the range of the non-adhesion portion 4n or does not overlap the second strength adhesion region A2 and in the vicinity of the edge. Is preferably provided.
In the illustrated example, the perforation line 6 (defect portion) coincides with an adjacent portion of the first strength adhesion region A1 and the second strength adhesion region A2 (the edge A2a of the second strength adhesion region A2) and is provided along the same. ing.

The vicinity of the adjacent portion where the defect portion is provided is preferably between the inner edge of the bonding portion 4p facing the adjacent portion of the inner edge of the bonding portion 4p and the adjacent portion (the edge of the second strength bonding region A2). And it is a position near an adjacent part. For example, referring to FIG. 12, the vicinity of the adjacent portion is between the inner edge 4pa of the bonding portion 4p and the edge A2a of the second strength bonding region A2, and is closer to the adjacent portion.
Preferably, in the vicinity of the adjacent portion, when the length between the inner edge of the adhesive portion facing the adjacent portion and the adjacent portion among the inner edges of the adhesive portion 4p is set to 100, it exceeds 0 from the adjacent portion and is 20% or less. It is within a range, and more preferably an arbitrary position within a range of more than 0 and not more than 10% from an adjacent site. If it is in such a range, when the skin pack package 1 is opened, the second layer 22 can be divided in the thickness direction at the perforation line 6 (defect portion) in the non-bonded portion 4n.

The specific numerical value varies depending on the size of the non-bonding part 4n, the formation range of the second strength bonding region A2, and the like, but the vicinity of the adjacent portion is, for example, a range exceeding 0 to 10 mm from the adjacent portion, preferably Is in the range of more than 0 and 10 mm or less from the adjacent site.
However, as shown in FIG. 10 of the first embodiment, when a plurality of the second strength adhesion regions A2 are independently provided in the region corresponding to the non-adhesion portion 4n, the adjacent portions where the defect portions are provided. The vicinity of the part is based on the second second strength adhesive region A2 that is closest to the inner edge of the adhesive portion 4p.

Only one perforation line 6 may be formed, but a plurality of perforation lines 6 may be provided in order to arrange a plurality of perforation lines 6 in a region corresponding to the non-bonded portion 4n. (Not shown). When a plurality of perforation lines 6 (missing portions) are provided in a region corresponding to the non-bonded portion 4n, at least one of them may be provided along or in the vicinity of the adjacent portion. .
The perforation line 6 does not have to be formed regularly like a straight line, and may be provided irregularly.

  The perforation line 6 only needs to penetrate the second layer 22 in the thickness direction, but the perforation line 6 is preferably penetrated to the first layer 21. It is troublesome to engrave the perforation line 6 only in the second layer 22 (it is easier to process the perforation line 6 on the mount 2 to which the first layer 21 and the second layer 22 are bonded) Further, by passing the perforation line 6 through the first layer 21 and the second layer 22, the through hole acts as the above-described vent hole.

  However, when the perforation line 6 is formed up to the first layer 21, similarly to the second layer 22, the breaking strength of the first layer 21 is reduced at the portion where the perforation line 6 is provided. In order to prevent the first layer 21 from being broken at the time of opening, the first layer 21 is set so that the breaking strength of the first layer 21 in the portion provided with the perforation line 6 (defect portion) is larger than the second strength. It is necessary to design the material, thickness, and shape of the perforation line 6.

  The perforation line 6 includes a plurality of intermittently formed through holes, and the shape of one through hole is generally a circular shape, a straight line shape, or a bent line shape. In order to ensure that the second layer 22 is broken at the perforation line 6, the through hole of the perforation line 6 is preferably linear or bent. Although the length of one through-hole is not specifically limited, For example, it is about 2 mm-10 mm.

When the skin pack package 1 of the present embodiment is also opened in the same manner as in the first embodiment, the first layer 21 is the second layer while the second layer 22 remains adhered to the skin pack film 4 in the bonding portion 4p. The delamination starts from 22. Furthermore, when the peeling point which advances by peeling reaches the adjacent site | part in the non-adhesion part 4n, the 2nd layer 22 will part in the thickness direction in a defect | deletion part. This is the same as the operation described in the first embodiment. Briefly, in the region corresponding to the non-bonded portion 4n and in the first strength bonding region A1, the second layer 22 has a breaking strength lower than the first strength, but the first layer does not reach the adjacent portion. The first layer 21 and the second layer 22 are delaminated. And when the said peeling point reaches an adjacent site | part, strong tensile force will be added to the 2nd layer 22, and in the defect | deletion part which exists in the 1st intensity | strength adhesion area | region A1 in the area | region corresponding to the non-adhesion part 4n, it is 2nd. Layer 22 breaks.
Therefore, after the adjacent portion, the second layer 22 bonded with the second strength follows the first layer 21 while adhering to the surface of the first layer 21, so that the non-adhesive portion 4 n which is a storage portion of the article 3 to be packaged. The mount 2 is removed from the opening, and the package 3 can be easily removed therefrom.

11 and 12, the perforation line 6 is illustrated as the defect portion formed in the second layer 22, but the defect portion is not limited to this, and may be, for example, a half cut line (not shown). The half-cut line is a cut that does not penetrate completely in the thickness direction of the second layer 22 but is cut in a substantially V-shaped cross section in the thickness direction of the second layer 22.
Further, in place of or in combination with the perforation line 6 and the half-cut line, innumerable fine holes may be formed in the second layer 22 corresponding to the non-bonded part 4n (not shown). ).

Moreover, although the said defect | deletion part illustrated the case where it provided along the adjacent part in the range of the non-adhesion part 4n, or its vicinity, a defect | deletion part does not necessarily follow the said adjacent part or its vicinity. It is not limited to the case where it is provided.
In the region corresponding to the non-bonded portion 4n and in the region bonded with the first strength, the defect portion is a region corresponding to the non-bonded portion 4n so that the second layer 22 has a small breaking strength. It is only necessary to be provided within the surface of the second layer 22 within the region bonded with the first strength.
However, since the tensile force applied to the second layer 22 is considered to act particularly strongly on the second layer 22 at or near the adjacent portion when the peeling point reaches the adjacent portion at the time of opening, the defect portion is It can be said that it is preferable to be provided along the adjacent part or its vicinity.

  Further, in this embodiment, the breaking strength of the second layer 22 itself (the breaking strength of the second layer in a state where no defect portion is provided) is greater than or substantially the same as the second strength. In addition, the second layer used in the first embodiment (a second layer having a breaking strength that is smaller than the second strength when no defect portion is provided) may be applied to the second embodiment.

[Third Embodiment]
In the skin pack package according to the third embodiment, the third layer is provided on the back surface of the first layer of the mount. Hereinafter, the third embodiment will be described. However, the same configurations and effects as those of the first and second embodiments (assuming that they have been described) may be omitted, and terms and symbols may be used. is there.

  The skin pack package 1 of the present embodiment is provided with a vent hole penetrating the first layer 21 and the second layer 22, and has a deaeration path on the back surface of the first layer 21. Similar to the second embodiment, except that the three layers 23 are bonded (the mount 2 has the second layer 22, the first layer 21, and the third layer 23 in order from the surface side). It is.

Specifically, as shown in FIGS. 14 to 16, the first layer 21 and the second layer 22 have perforation lines 7 (vent holes) penetrating in the thickness direction thereof as in the second embodiment. Is drilled.
The breaking strength of the second layer 22 corresponding to the non-bonded portion 4n is lower than the second strength at least at the portion of the perforation line 7.
Examples of the perforation line 7 include those exemplified in the second embodiment.
In the illustrated example, the perforation line 7 extends in the vertical direction from the upper edge to the lower edge of the first layer 21 and the second layer 22 at the center in the left-right direction of the first layer 21 and the second layer 22. The perforation line 7 is not limited to one, and a plurality of perforation lines 7 may be provided.

The third layer 23 is provided on the back surface of the first layer 21 via the adhesive layer 8. The deaeration path 5 is provided between the third layer 23 and the first layer 21. The deaeration path 5 communicates with the perforation line 7 formed in the first layer 21 and the second layer 22 and also communicates with the edges of the third layer 23 and the first layer 21.
The deaeration path 5 is a path that guides the air between the surface of the second layer 22 and the back surface of the skin pack film 4 from the back surface side of the first layer 21 to its edge during vacuum suction.

The deaeration path 5 is formed by interspersing an adhesive layer 8 for bonding the first layer 21 and the third layer 23 in a plurality of regions, thereby forming gaps between the regions where the adhesive layers 8 are formed. It is secured. A portion indicated by light ink painting in FIG. 16 is an area where the adhesive layer 8 is provided, and a plain portion in FIG. 16 is the deaeration path 5.
The adhesive layer 8 can be formed by a known adhesive (solvent adhesive, heat-sensitive adhesive, UV curable adhesive, etc.), and the adhesive layer 8 extremely strongly bonds the first layer 21 and the third layer 23 together. Is. For example, the adhesive layer 8 adheres the first layer 21 and the third layer 23 with an adhesive strength substantially the same as or higher than the adhesive strength between the skin pack film 4 and the second layer 22 in the adhesive portion 4p.

The formation region of the adhesive layer 8 is particularly limited on condition that the adhesive layer 8 does not overlap the perforation line 7 on all the cuts (provided that all the air holes are not blocked by the adhesive layer 8). Instead, a part of the adhesive layer 8 may overlap a part of the perforation line 7.
In the illustrated example, the adhesive layer 8 is formed so that the adhesive layer 8 does not overlap all the perforation lines 7.
Further, the adhesive layer 8 is provided up to the peripheral edge portion including the four corners of the first layer 21 so that the peripheral edge portion of the first layer 21 and the peripheral edge portion of the third layer 23 are not broken.

In addition, a desired design is represented on the front surface or back surface of the first layer 21 or / and the front surface of the second layer 22 or / and the front surface or back surface of the third layer 23 as necessary. Also good.
When the first layer 21, the second layer 22, and the third layer 23 are all transparent, the design is printed on the back surface of the third layer 23 so that the design display can be seen from the front side of the mount 2 in the correct orientation. May be.

The skin pack package 1 of this embodiment is manufactured as follows.
The surface of the mount 2 is covered with an article 3 to be wrapped, and the softened skin pack film 4 is placed thereon, and the air between the mount 2 and the skin pack film 4 is sucked in a vacuum atmosphere, The air reaches the back side of the first layer 21 through the vent holes of the second layer 22 and the first layer 21 of the mount 2, and further, the air moves along the surface through the deaeration path 5 and is sucked to the edge. It will be discharged.
The suction of the air causes the skin pack film 4 to expand and adhere to the package 3, and the skin pack film 4 adheres to the surface of the mount 2 where the package 3 does not exist. Adhere to the surface.
In this way, the skin pack package 1 of the third embodiment is obtained.

Similarly to the second embodiment, the skin pack package 1 of the present embodiment also delaminates the first layer 21 (and the third layer 23) from the second layer 22, and the separation point is the perforation line 7. The second layer 22 is divided in the thickness direction, and the mount 2 is removed from the non-adhesive part 4n which is the storage part of the article 3 to be opened, and the article 3 is easily removed therefrom. be able to.
In addition, since the third layer 23 is formed on the back surface side of the first layer 21 without a vent hole such as a perforation line, when viewed from the back surface of the mount 2 (the back surface of the third layer 23). Further, the perforation line 7 formed in the first layer 21 can be hidden so as not to be seen.

  In addition, although the skin pack package 1 of 3rd Embodiment uses the thing of the said 2nd Embodiment as a structure of the skin pack film 4, the to-be-packaged object 3, the 1st layer 21, and the 2nd layer 22, this is used.
