Description

  The present invention relates to a skin pack mount and a skin pack package for holding an object to be packaged with a skin pack film.

The skin pack package includes a mount, a package on the surface of the mount, and a skin pack film including the package and adhered to the surface of the mount.
Such a skin pack package includes a step of placing an article to be packaged on a surface of a mount having an adhesive layer provided on the surface, a step of covering a softened skin pack film thereon, and vacuum-sucking the film to form a skin pack film. Can be manufactured by a step of adhering the skin pack film to the surface of the mount while extending along the outer shape of the package (Patent Document 1).

  Patent Document 1 discloses a non-breathable skin pack mount provided with a perforation line. In the skin pack package using this mount, the perforation line becomes a degassing opening at the time of manufacture, and the perforation line becomes the tearing starting point of the mount at the time of opening.

  However, in the skin pack mount of Patent Document 1, the skin pack film adheres sufficiently on the surface of the mount in the vicinity of the perforation line, but poor adhesion in the area away from the perforation line. There is a problem of producing. In particular, there is a problem that the skin pack film does not adhere to the surface of the mount or adheres very weakly as it approaches the peripheral edge of the mount (that is, the region farther from the perforation line). For this reason, in the skin pack package using the mount, there is a possibility that the appearance will be lowered due to the accumulation of air everywhere on the mount, or the skin pack film may be easily drawn from the mount.

Japanese Patent Laid-Open No. 2003-020068

A first object of the present invention is to provide a skin pack mount capable of adhering a skin pack film not only in the vicinity of a through-hole but also in a wide range.
The second object of the present invention is to provide a skin pack package in which the skin pack film is adhered to a wide range of the mount and is excellent in openability.

As a result of intensive studies on the cause of the above problems, the present inventors have found the following.
When manufacturing the skin pack package as described above, the skin pack film is put on the surface side of the mount having the adhesive layer on the surface with the packaged material interposed therebetween, and vacuum suction is performed from the back side of the mount. Then, the skin pack film is adhered to the mount, and the skin pack film is adhered to the adhesive layer of the mount.
At the time of vacuum suction, the air existing between the back surface of the skin pack film and the front surface of the mount can smoothly escape from the perforation line to the back surface of the mount.
However, as the air escapes from the perforation line, the skin pack film quickly adheres to the surface of the mount in the area near the perforation line on the surface of the mount. For this reason, the air which exists in the place away from the perforation line is not sucked from the perforation line. As a result, an air pocket is randomly generated between the skin pack film and the mount, and a package body in which the skin pack film does not adhere or weakly adheres to the surface of the mount is obtained.

  The skin pack mount of the present invention has a non-breathable base material that holds an object to be packaged in cooperation with the skin pack film, and a through-hole penetrating in the thickness direction is formed in the base material. The surface of the substrate has a region formed in a concavo-convex shape having a convex portion and a concave portion, and the concave portion extends from the through hole toward the end portion of the base material, and the convex portion At least one of the surface of the surface and the surface of the recess can be adhered to the skin pack film.

On the surface of the base material for the skin pack mount, a recess extending in the end direction from the through hole is formed. When the skin pack film is put on the surface of the mount and the skin pack film is sucked, an air escape path is secured between the concave portion and the skin pack film from the through hole toward the end of the base material. For this reason, when the air between the mount and the skin pack film is sucked, the base material and the skin pack film do not tightly adhere to each other in the initial stage of suction, and the air away from the through hole also passes through the recess (exit). Collected in the through hole and sucked. As the air is sucked, the skin pack film adheres to at least the convex portion or the concave portion, and a skin pack package is obtained.
If the mount for skin packs of this invention is used, the air between a mount and a skin pack film can be attracted | sucked extensively through a through-hole. Therefore, it is possible to obtain a skin pack package in which the skin pack film is adhered to the mount in a wide range.

A preferable skin pack mount of the present invention has a sea-island structure in which the region formed in the concavo-convex shape has the convex portion as an island and the concave portion as the sea, and a plurality of the convex portions are independently formed. .
In a more preferred skin pack mount of the present invention, a plurality of convex portions that are islands of the sea-island structure are regularly arranged in the form of dots in the sea.
In a further preferred skin pack mount of the present invention, the sea-island structure is provided on the entire surface of the substrate.
In a more preferred skin pack mount of the present invention, the shape of the projection in plan view is a circle, an ellipse, or a polygon.

  In a preferred skin pack mount of the present invention, the convex portion is formed in a ring shape in a plan view on the peripheral end portion of the surface of the mount, and the concave portion is surrounded by the annular convex portion and the penetrating It is formed in a range including holes, the surface of the annular convex portion can be adhered to the skin pack film, and the surface of the concave portion cannot be adhered to the skin pack film.

According to another aspect of the present invention, a skin pack package is provided.
This skin pack package includes any one of the above skin pack mounts, a package, and a skin pack film, and the package is attached to the surface side of the base material of the skin pack mount, The skin pack film is in close contact with the article to be packaged and is adhered to at least one of the surface of the convex portion and the surface of the concave portion of the substrate.

If the skin pack mount of the present invention is used, a skin pack package in which the skin pack film is adhered over a wide range can be constituted.
Moreover, since the skin pack film of the present invention has the skin pack film adhered to a wide area of the mount, the skin pack film is difficult to be inadvertently rolled. Furthermore, since the skin pack package can break the mount using the through holes, the skin pack package is also excellent in unsealing properties.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings as appropriate.
In this specification, the “surface” of a certain member is on the near side (side closer to the viewer) when the skin pack mount body is viewed from the front (direction in which the surface of the mount is directly viewed) shown in FIG. It refers to a surface, and the “back surface” of a member refers to the opposite surface. The plan view shape is a shape when viewed from the vertical direction with respect to the front surface or the back surface of the mount. In the vertical direction, a state in which any one side of the mount of the skin pack packaging body is set up on a horizontal plane (for example, a state where the mount is set up by placing the lower edge of the mount on the horizontal plane as shown in FIG. 1) is assumed. Thus, the vertical direction refers to the vertical direction, and the width direction refers to the direction perpendicular to the vertical direction within the plane of the mount.
In addition, the description “PPP to QQQ” means “PPP or more and QQQ or less”.
Further, in the present invention, the “paper” of the mount does not have a limited meaning “the mount is made of paper”. It should be noted that the specific dimensions and scale ratios of each figure are different from the actual ones. In each plan view, countless small dots are added to the convex portions for the sake of convenience in order to make the range in which the convex portions are provided easy to understand.

(Skin pack mount)
1 to 4, the skin pack mount 1 has a non-breathable base material 2 and an adhesive layer formed on the surface of the base material 2. The base material 2 holds an article to be packaged in cooperation with the skin pack film. The surface of the substrate 2 is formed in a concavo-convex shape having convex portions 3 and concave portions 4. In the present embodiment, the surface of the convex portion 3 can be adhered to the skin pack film. The convex portion 3 corresponds to an adhesive layer. The surface of the recess 4 cannot be adhered to the skin pack film. A through hole 5 is formed in the base material 2 so as to penetrate in the thickness direction of the base material 2. The recess 4 extends from the through hole 5 in the direction of the end of the substrate 2.
This will be specifically described below.

The base material 2 is, for example, a substantially flat sheet having flexibility. The base material 2 is non-breathable so that air does not substantially permeate in the thickness direction. The non-breathability means that the air does not substantially move from the front surface side to the back surface side of the substrate 2 when air is sucked from the back surface side of the substrate 2.
The main forming material of the base material 2 is not particularly limited, and is a single layer sheet such as cardboard, coated paper, synthetic paper, synthetic resin sheet, and foamed resin sheet, and a laminated sheet in which these two or more sheets are laminated and bonded. These are various sheets. The sheet includes what is generally called a film. When a sheet having air permeability in the thickness direction is the main forming material of the base material 2 such as the cardboard, the non-breathing material such as a coat layer or a synthetic resin film is formed on the front and / or back surface of the air-permeable sheet. Are stacked. 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.

The substrate 2 is, when it is formed of paper such as coated paper, its weight per unit area is, for ^{example, 20g / m 2 ~600g / m 2} , ^preferably, 100 g / m 2 to 500 g / ^{m 2} is there. When the said base material 2 is formed with the synthetic paper, the synthetic resin sheet, or the foamed resin sheet, the thickness is 20 micrometers-800 micrometers, for example, Preferably, they are 50 micrometers-500 micrometers. A design may be displayed on the front surface and / or back surface of the base material 2 by printing or the like as required (not shown).

  In the surface of the substrate 2, a through hole 5 that penetrates in the thickness direction of the substrate 2 is formed. In the present embodiment, the through hole 5 is formed of a long and narrow cut line. The number of the through holes 5 may be one, but a plurality is preferably provided.

  The through-hole 5 is provided at an appropriate position of the base material 2, but preferably one or a plurality of through-holes 5 are provided at a position hidden by an article to be packaged attached to the base material 2. In addition, you may provide the said through-hole 5 in the range which is the periphery of the said position and does not impair openability. In other words, the through hole 5 is formed at a position so as to overlap with the planar projection shape of the packaged object. The planar projection shape is a shadow shape reflected on the surface of the base material 2 when a parallel light beam is applied to the surface of the base material 2 from the vertical direction in a state where the package is placed on the surface of the base material 2. is there. For example, when the packaged object has a substantially cylindrical shape, the planar projection shape is rectangular or square, and when the packaged object has a substantially truncated cone shape, the planar projection shape is trapezoidal or circular. .

When a plurality of the through holes 5 are provided, their arrangement can be set as appropriate. For example, in the illustrated example, two columns in which a plurality of through-holes 5 are arranged in the vertical direction with a slight gap are provided with two gaps in the width direction, and a width is provided at each lower end of the two columns. A row in which a plurality of through-holes 5 are arranged in the direction with a small gap is provided. Therefore, the set of the plurality of through holes 5 has a substantially U shape in plan view as a whole. Such a set of through holes 5 can be said to be a perforation line having a relatively long cut. When a plurality of the through-holes 5 are provided, it is preferable that at least one of the plurality of through-holes 5 is formed at a position so as to overlap the planar projection shape of the package. In addition, in each figure, the case where all the some through-holes 5 are formed in the position which overlaps with the planar projection shape of a to-be-packaged object is illustrated.
The length of the through-hole 5 (elongated cut line) and the interval between adjacent through-holes 5 are not particularly limited, but the length of the through-hole 5 is relatively long (for easy opening of the package) ( For example, the interval between the adjacent through holes 5 is preferably relatively short (for example, 0.5 mm to 2 mm).

  When a plurality of the through holes 5 are provided, the set of the through holes 5 may be a normal perforation line. A normal perforation line is a perforation line having a relatively short cut (the cut corresponds to the through hole 5), and a plurality of the perforations are formed intermittently. The relatively short cut is linear in plan view, substantially circular in plan view, and the length thereof is, for example, about 0.2 mm to 2 mm, and the interval between adjacent short cuts is, for example, 0.5 mm. About 2 mm. When the short cut is linear, the length of the cut corresponds to the linear distance between both ends. When the short cut has a substantially circular shape, the length of the cut corresponds to the diameter. In the present specification, the substantially circular shape means a perfect circle or an ellipse.

  A plurality of convex portions 3 that can be bonded to the skin pack film are provided on the surface of the substrate 2. The plurality of convex portions 3 are independent from each other, and are arranged on the surface of the base material 2 at intervals. A recess 4 is present between the plurality of protrusions 3. The recess 4 extends from the through hole 5 in the direction of the end of the substrate 2. Since there are a plurality of recesses 4 between the plurality of protrusions 3, the plurality of recesses 4 extend from the through hole 5 to the peripheral end of the base material 2. The region formed in the concavo-convex shape having the convex portion 3 and the concave portion 4 extends to the peripheral region with the through hole 5 as a reference. The region formed in the concavo-convex shape has a sea-island structure in which a plurality of independent convex portions 3 are islands and the concave portions 4 are seas. The concave portion 4 that is the sea of the sea-island structure extends from the through hole 5 to the peripheral end portion of the base material 2 like a mesh thread in plan view.

  The region of the sea-island structure is provided over the entire surface of the substrate 2. Accordingly, the concave portion 4 extends from the through hole 5 to the entire edge of the base material 2. In other words, the plurality of recesses 4 extend radially from the through hole 5 to the periphery of the substrate 2. In addition, the edge of the base material 2 points out one side part which comprises the external shape of a mount. The peripheral edge of the base material 2 (all the edges of the base material) refers to all the side portions constituting the outline of the mount. The edge part of the said base material 2 points out the area | region from the edge of the base material 2 to the location which entered a little inside from the edge. The peripheral edge of the base material 2 refers to the peripheral edge of the base material 2 and an annular region from the peripheral edge to a place slightly inside. The width of the end portion of the base material 2 (the length from the edge of the base material to a position slightly inside) depends on the size of the mount, but is, for example, 5 mm to 15 mm.

  The concave portion 4 is a portion for forming an air passage. That is, the concave portion 4 covers the skin pack film on the surface side of the mount (base material 2), and when the skin pack film comes into contact with the top of the convex portion 3, the air passage between the concave portion 4 and the skin pack film is provided. This is the part to be formed.

  In this embodiment, the said convex part 3 is formed by adhering to the surface of the base material 2 the adhesive material which has adhesiveness with respect to a skin pack film. Therefore, the surface of the convex portion 3 is made of the adhesive material, and the surface of the concave portion 4 is made of the surface of the substrate 2. In the present embodiment, the surface of the recess 4 cannot be adhered to the skin pack film. In addition, the part which the through-hole 5 cross | intersects among the said convex parts 3 is penetrated. That is, the through hole 5 penetrates in the thickness direction of the base material 2 and the convex part 3. The adhesive material for forming the convex portion 3 (adhesive layer) is not particularly limited as long as it is firmly bonded to the surface of the substrate 2 and the back surface of the skin pack film, and a conventionally known material can be used. it can. Examples of the adhesive material forming the convex portion 3 include a heat-sensitive adhesive and a heat-sensitive adhesive. By using a heat-sensitive adhesive material, the skin pack base 1 can be stored and transported without temporarily attaching the skin pack base 1 to the release paper. That is, the skin pack mount 1 can be stored and transported without using a release paper that is unnecessary in the future. As will be described later, since the heat-sensitive adhesive material can be bonded by the heat of the original skin pack film itself during the manufacture of the skin pack package, the skin-pack packaging can be easily performed by using the heat-sensitive adhesive material. You can get a body.

  The heat-sensitive adhesive is an adhesive that is solidified at room temperature and is activated by heating to exhibit adhesiveness, and is solidified by cooling to adhere an object. The heat-sensitive pressure-sensitive adhesive is an adhesive that is solidified at room temperature and is activated by heating to exhibit adhesiveness to adhere an object, and the pressure-sensitive adhesive continues even after cooling. Examples of the heat-sensitive adhesive or heat-sensitive adhesive include delayed tack type, emulsion type, solvent type, and hot melt type.

  The delayed tack type heat-sensitive adhesive is an adhesive that does not exhibit adhesiveness at room temperature, exhibits adhesiveness by heating, and maintains the adhesiveness for a long time after cooling. The delayed tack-type heat-sensitive adhesive can be applied by a printing method such as gravure coating. Examples of the delayed tack type heat-sensitive adhesive include a base resin such as an ethylene-vinyl acetate copolymer, a vinyl acetate-acrylic ester copolymer, or a synthetic rubber, a tackifier, and a solid plasticizer. Examples thereof include an adhesive containing an additive. Examples of the emulsion-type or solvent-type heat-sensitive adhesive or heat-sensitive adhesive include, for example, a heat-adhesive resin such as ethylene-vinyl acetate copolymer, a tackifier, various additives, A solution containing water or an organic solvent to be dissolved. The emulsion-type or solvent-type heat-sensitive adhesive or heat-sensitive adhesive can be applied by a printing method such as gravure coating. The emulsion-type or solvent-type heat-sensitive adhesive or heat-sensitive adhesive is used after being coated and dried. Examples of the hot-melt type heat-sensitive adhesive or heat-sensitive adhesive include bases such as ethylene resins (ethylene-vinyl acetate copolymers, ethylene acrylic acid copolymers, etc.) or styrene-butadiene block copolymers. Examples thereof include an adhesive or a pressure-sensitive adhesive containing a resin, a tackifier, and various additives. The hot-melt type heat-sensitive adhesive or heat-sensitive adhesive can be applied by heating and melting using a hot-melt coater or an extrusion laminator.

  Usually, a heat-sensitive adhesive or a heat-sensitive adhesive having a softening point of 60 ° C to 180 ° C is used. Preferably, a heat-sensitive adhesive or pressure-sensitive adhesive having a softening point of 70 ° C. or higher is used, and more preferably, a heat-sensitive adhesive or pressure-sensitive adhesive having a softening point of 80 ° C. or higher is used. When the convex portion 3 is formed using a heat-sensitive adhesive or the like having a low softening point, the convex portion 3 is quickly crushed by the skin pack film that is in close contact with the top of the convex portion 3 during suction, and the concave portion 4 disappears. There is a risk. If the convex portion 3 and the concave portion 4 disappear at an early stage, there is a possibility that the air between the mount and the skin pack film and away from the through hole cannot be reliably sucked. On the other hand, the softening point of the heat-sensitive adhesive or heat-sensitive adhesive is preferably 160 ° C. or less, and more preferably 140 ° C. or less. If a heat-sensitive adhesive with a softening point that is too high is used, depending on the type of skin pack film, it may be thermally damaged. The softening point can be measured according to JIS K 6863.

  The adhesive strength of the protrusion 3 (adhesive material) to the skin pack film is not particularly limited as long as the base material 2 and the skin pack film are not easily peeled off. If the adhesive strength is too small, the skin pack film may be inadvertently peeled off from the substrate 2. Considering this, the adhesive strength of the convex portion 3 is, for example, 3 N / 15 mm or more, and preferably 5 N / 15 mm or more. On the other hand, if the skin pack film adheres to the convex portion 3 too firmly, it is difficult to open the package. Considering this, the adhesive strength of the convex portion 3 is, for example, 25 N / 15 mm or less, and preferably 20 N / 15 mm or less.

  However, the said adhesive strength says the value measured by the method according to 180 degree peeling of JISZ0237 (2009). Specifically, the adhesive strength is obtained by cutting a substrate 2 and a skin pack film bonded to each other through an adhesive material having a thickness of 80 μm into a size of 100 mm × 15 mm, a temperature of 23 ± 2 ° C., a humidity of 50 ± 5% RH, The maximum strength when peeled at a speed of 300 mm / min.

  In addition, that the surface of the said recessed part 4 cannot adhere | attach on a skin pack film means that the surface of the recessed part 4 does not adhere | attach substantially on a skin pack film. “Not substantially bonded” means bonded in a close contact state (that is, in contact but not bonded), or in a slight adhesive strength (for example, an adhesive strength exceeding 0 and 1 N / 15 mm or less). This means a pseudo-adhesive state.

  The planar view shape and the cross-sectional view shape of the convex portion 3 are not particularly limited and can be set as appropriate. For example, the planar shape of the convex part 3 may be a circular shape as illustrated. In addition, although not illustrated, the planar shape of the convex portion 3 includes an elliptical shape, a polygonal shape such as a triangular shape or a quadrangular shape, a star shape, an elongated belt shape, or any other irregular shape. Moreover, the cross-sectional view shape of the convex part 3 includes a semi-elliptical shape or a semi-circular shape as illustrated. In addition, although not illustrated, the cross-sectional shape of the convex portion 3 may be a polygonal shape such as a triangular shape, a quadrangular shape, or a trapezoidal shape.

  The top of the convex portion 3 may be substantially flat, or may be a substantially hemispherical swell in a direction away from the base material 2 or a substantially hemispherical swell in a direction approaching the base material 2. The term “flat” refers to a plane parallel to the horizontal plane. The convex portion 3 in the illustrated example is a dome shape having a semi-elliptical sphere or semi-spherical top (the cross-sectional shape is a semi-elliptical or semi-circular shape). By forming the convex part 3 in a dome shape, the skin pack film adheres well to the convex part 3 while securing the escape path by the concave part 4.

  The plurality of convex portions 3 may be arranged randomly or regularly. Since the regular concave portions 4 can be formed, the plurality of convex portions 3 that are islands of the sea-island structure are preferably regularly arranged in the sea, and are further regularly arranged in a dot shape. More preferred. The skin pack mount 1 having the regular recesses 4 can suck air substantially uniformly from the peripheral end of the substrate 2 to the through holes. Further, by arranging the plurality of convex portions 3 regularly in a dot shape, a skin pack package in which the skin pack base 1 is bonded to the skin pack film with substantially uniform adhesive strength can be obtained. .

  In the illustrated example, the plurality of convex portions 3 are provided at equal intervals in the vertical direction and the width direction of the substrate 2. The interval between the adjacent convex portions 3 (this interval is equal to the width of the concave portion 4) is not particularly limited, but if it is too small, there is a possibility that a good passageway cannot be formed. Considering this, the interval between the adjacent convex portions 3 is 0.05 mm or more, preferably 0.08 mm or more. On the other hand, even if the space | interval of the adjacent convex part 3 is large, it does not cause trouble on attraction | suction of air. However, if the interval between the adjacent convex portions 3 is too large, the width of the concave portion 4 becomes relatively large, and the ratio of the area where the skin pack film does not adhere to the mount increases too much. Considering this, the interval between the adjacent convex portions 3 is, for example, 10 mm or less, preferably 5 mm or less. In addition, when the space | interval of the said convex part 3 changes with selection of the said adjacent convex part 3, the space | interval of the said adjacent convex part 3 means the minimum value in it.

The area of one convex part 3 is not particularly limited, but if it is too large or too small, the area occupied by the concave part 4 is relatively reduced or increased. In view of this, the area of one convex portion 3 is ^{1.5 × 10 -3 mm 2 ~10.0mm 2} , is ^{preferably, 5.0 × 10 -3 mm 2 ~5.0mm} 2 . In addition, the area of the convex part in this specification is not the surface area of the convex part 3, but the area of the planar view shape of the convex part 3.
In the sea-island structure region, the total area of the protrusions 3 can be set as appropriate. For example, in the sea-island structure region, the ratio of the total area of the protrusions 3 is 40% to 80%, preferably 50% to 80%, more preferably 60 when the entire sea-island structure region is 100. % To 70%. If the total area of the convex portions 3 with respect to the entire region of the sea-island structure is too small, the skin pack film may not adhere to the mount with sufficient strength. If the total area of the convex portions 3 with respect to the entire region of the sea-island structure is too large, there is a possibility that a passage that leads to the through hole 5 cannot be secured. However, the ratio of the total area of the convex part 3 can be calculated by the following equation. Ratio (%) of total area of convex parts = (sum of areas of all convex parts / area of entire region of sea-island structure) × 100.
The height of the convex part 3 is not particularly limited, but if it is too small, the concave part 4 hardly occurs, and there is a possibility that a good escape path cannot be formed. Considering this, the height of the convex portion 3 is, for example, 0.01 mm or more, and preferably 0.05 mm or more. On the other hand, if the height of the convex portion 3 is too large, a skin pack package having a gap between the back surface of the skin pack film and the bottom portion of the concave portion 4 may be obtained. Considering this, the height of the convex portion 3 is, for example, 1 mm or less, and preferably 0.8 mm or less. In addition, the height of the said convex part 3 means the straight line length between the highest part of the convex part 3, and the base part of this convex part 3 (this base part is a boundary part with the recessed part 4). This straight line length is a straight line length in the vertical direction with respect to the surface of the substrate 2.

(Skin pack package)
Next, a method for producing the skin pack package of the present invention will be described.
Usually, a plurality of skin pack packages are manufactured at the same time using a relatively large shape of a mounting board and a manufacturing skin pack film.
Hereinafter, the manufacturing board used at the time of manufacturing is referred to as “original board”, and the manufacturing skin pack film used at the time of manufacturing is referred to as “original skin pack film”.

  The same skin pack package means a skin pack package having substantially the same holding position of the package with respect to the design displayed on the mount, and preferably a skin pack package having the same shape in plan view of the mount. means. The direction of “up” and “down” used in the explanation column of the manufacturing method is, for convenience, the state where the back surface of the mount is placed on the horizontal plane, and the side away from the horizontal plane is “up”, and vice versa. The side is “down”.

The base material constituting the base paper (hereinafter referred to as “original base material”) is usually larger than the base material 2 of the skin pack base 1. That is, the skin pack mount 1 is used for one skin pack package, and the original mount at the time of manufacture has a size that can finally cut out a plurality of skin pack packages.
FIG. 5 shows the original mount 1P. For example, six skin pack packages can be obtained from the base paper 1P. That is, when the base sheet 1P shown in FIG. 5 is used, a skin pack package can be manufactured in 2 rows × 3 columns = 6 sections as seen in the plane.
The same design is printed and displayed on each of the six sections on the base material 2P constituting the base paper 1P (design display is not shown). The design of each section is printed regularly at regular intervals in the vertical and horizontal directions. The planar view shape of the base paper 1P is not particularly limited, but normally, a rectangular base paper 1P is used as illustrated.

A region (sea-island structure) formed in a concavo-convex shape having the convex portions 3 and the concave portions 4 is formed on the entire surface of the raw substrate 2P. Since the details of the convex part and the concave part are the same as the description column of the above-mentioned skin pack mount, they are omitted here. However, it should be noted that the projections and the recesses are not shown in each drawing shown in the description of the manufacturing method (except for FIG. 10).
For example, a plurality of adhesive convex portions can be formed by fixing a thermosensitive adhesive as an adhesive material in a plurality of dots on the surface of the raw substrate 2P. The through-hole 5 is formed in the surface of the raw substrate 2P having the uneven surface. The through-hole 5 can be formed by, for example, pushing a cutting blade from the front surface or the back surface of the raw substrate 2P. The through hole 5 is formed at a specific position (the same position in each section) with respect to each design of the six sections.

If necessary, a through hole other than the through hole 5 (hereinafter referred to as “auxiliary through hole”) may be formed in the raw substrate 2P. By providing the auxiliary through hole 7, the air between the base paper 1P and the original skin pack film can be quickly sucked. The auxiliary through hole 7 may be formed at an appropriate position on condition that it is formed at a position including at least the concave portion 4. Of course, in the base paper 1P having a relatively large shape, it takes time to suck air in the region between the through holes 5 formed in each section. 7 is not very effective. Therefore, it is preferable that the auxiliary through hole 7 is provided at the boundary of each section or in the vicinity thereof.
Although the number of the auxiliary through-holes 7 may be one, it is usually preferable to intermittently provide a plurality of auxiliary through-holes 7 along the boundaries of the sections or in the vicinity thereof. That is, as one preferable aspect, a set of a plurality of auxiliary through holes 7 is provided along the boundary of each section or the vicinity thereof. The set of auxiliary through holes 7 includes a perforation line having a relatively short cut (corresponding to the auxiliary through hole 5) and a relatively long cut (the auxiliary through hole 5) as described in the set of the through holes 5. Perforation line having the equivalent).

  In particular, when the skin pack package is finally obtained, in order to prevent the auxiliary through holes 7 from remaining on the mount of the package, as shown in FIG. It is preferable to form the auxiliary through hole 7. The ear region of the raw base material 2P is a portion that is removed when individual skin pack packages are obtained in a finishing process described later.

  Next, as shown in FIG. 6, an article A to be packaged is placed on the surface of the original mount 1P. The article A to be packaged is placed at a specific position corresponding to each design of the six sections. Preferably, the package A is placed at a specific position where the through-hole 5 is hidden by the planar projection shape of the package A. The package A is not particularly limited, and includes various containers such as a spray container, a container with a cap, and a bottle container in which cosmetics are stored. The outer shape of the package A is not particularly limited, and examples thereof include a polygonal column shape such as a columnar shape, an elliptical column shape, and a quadrangular column shape, a truncated cone shape, and an elliptical truncated cone shape. In FIG. 6, an article having a quadrangular prism shape is illustrated.

  Next, as shown in FIG. 7, the original skin pack film 6 </ b> P is covered from the surface side of the original mount 1 </ b> P on which the article A to be packaged is placed, including the article A to be packaged. The original skin pack film 6P is larger than the original mount 1P. In the example of illustration, the case where the raw skin pack film 6P larger than the substantially flat base paper 1P and similar in shape to the original paper 1P is used is illustrated.

  As the original skin pack film 6P (skin pack film), a conventionally known film can be used on condition that the original skin pack film 6P (skin pack film) is a film that can sufficiently adhere to the convex portion 3 that is an adhesive layer. As the original skin pack film 6P, a colorless transparent or colored transparent single layer or multilayer resin film is usually used. The film includes what is generally called a sheet. The thickness of the original skin pack film 6P is not particularly limited, and is, for example, 30 μm to 300 μm, preferably 60 μm to 200 μm.

  The material of the original skin pack film 6P is not particularly limited, and examples thereof include thermoplastic resins such as polyolefin resins, polyamide resins, polyester resins, ethylene-vinyl acetate copolymers, and soft vinyl chloride. Examples of the polyolefin resins include polyethylene resins such as linear low density polyethylene, low density polyethylene, medium density polyethylene, and high density polyethylene; polypropylene resins such as polypropylene; propylene-ethylene copolymers, ethylene-acetic acid. And various copolymers such as vinyl copolymers, ionomer resins, ethylene- (meth) acrylic acid copolymers, and ethylene- (meth) acrylic acid-unsaturated carboxylic acid ester copolymers. Of these, polyethylene resins are preferable, and linear low density polyethylene is more preferable. These may be used alone or in combination of two or more. Examples of the polyamide-based resin include aliphatic polyamide polymers such as nylon 6, nylon 66, nylon 69, nylon 610, nylon 612, nylon 11 and nylon 12; nylon 6-66 (6-66 is nylon 6 and Represents a copolymer of nylon 66. The same shall apply hereinafter), aliphatic polyamide copolymers such as nylon 6-10, nylon 6-12, nylon 6-69, nylon 6-610, nylon 66-69; Etc. Among these, an aliphatic polyamide copolymer is preferable, and nylon 6-66, nylon 6-10, or nylon 6-12 is more preferable. These may be used alone or in combination of two or more. Typical examples of the polyester resin include polymers such as poly (ethylene terephthalate), poly (butylene terephthalate), poly (ethylene terephthalate / isophthalate), poly (ethylene glycol / cyclohexanedimethanol / terephthalate), and the like. A resin obtained by polymerizing the polymer and another copolymer component; and the like. Examples of the other copolymer components include diols such as ethylene glycol, butylene glycol, cyclohexanedimethanol, neopentyl glycol, and pentanediol; isophthals, benzophenone dicarboxylic acid, diphenylsulfone dicarboxylic acid, diphenylmethane dicarboxylic acid, propylene bis (phenyl) Carboxylic acid), diphenyl oxide dicarboxylic acid, oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, suberic acid, azelaic acid, sabatic acid, diethyl succinic acid and the like. These may be used alone or in combination of two or more.

  As the original skin pack film 6P, it is preferable to use a film having a multilayer structure having at least two layers of resins having different melting points. In particular, use a film composed of two or three layers with a high melting point resin (that is, a resin having heat resistance) as an intermediate layer and a lower melting point resin than the intermediate layer resin as a surface layer and a back layer. Is more preferable. In the film composed of the two types and three layers, a resin (high melting point resin) having higher heat resistance than a low melting point resin contributing to adhesion to the mount is laminated as an intermediate layer. When a film composed of such two types and three layers is used as the original skin pack film 6P, it can be heated to a high temperature. Therefore, for example, even if the bonding process for bonding the original skin pack film 6P to the base paper 1P is performed in the open air, the original skin pack film 6P can be heated to an appropriate temperature, so that the working efficiency of the bonding process can be improved. It can be improved. Furthermore, since the film composed of the two types and three layers is difficult to curl after heating, a skin pack package with a good finish can be obtained by using this as the original skin pack film 6P.

Examples of the film composed of two types and three layers include, for example, polyolefin resin (low melting point resin) / polyolefin resin (high melting point resin) / polyolefin resin (low melting point resin), polyolefin resin / polyamide type. Examples thereof include resins / polyolefin resins, polyolefin resins / polyester resins / polyolefin resins, and preferred are polyolefin resins / polyamide resins / polyolefin resins. Among them, the polyolefin resin is either a linear low density polyethylene or low density polyethylene, and the polyamide resin is an aliphatic polyamide copolymer. The raw skin pack film 6P is particularly preferably used.
When adhering the original skin pack film 6P to the original mount 1P, the original skin pack film 6P extends along the shape of the package object, as will be described later. For this reason, the original skin pack film 6P is a film that can be softened to such an extent that it can be stretched. The raw skin pack film 6P made of the material as described above can be usually softened by heating. An original skin pack film 6P that is sufficiently soft at room temperature may be used in nature, and when such a film is used, the heating is omitted.

The original skin pack film 6P is usually flexible. In order to convey the flexible original skin pack film 6P, a detachable holding frame 99 is attached around the original skin pack film 6P as shown in FIG.
The holding frame 99 includes a pair of upper and lower frames (an upper frame 991 and a lower frame 992). The upper frame 991 and the lower frame 992 have a hollow rectangular shape (frame shape). The upper frame 991 and the lower frame 992 are made of a material having no air permeability, and are made of, for example, metal, synthetic resin, or the like. The periphery of the original skin pack film 6P is sandwiched between the upper frame 991 and the lower frame 992, and fixed so that the upper frame 991 and the lower frame 992 are not separated from each other. 99.

  The original skin pack film 6P is heated and softened. For example, in a state where the original skin pack film 6P is held by the holding frame 99, a heating device such as a far-infrared heater is used to heat the original skin pack film 6P from the front surface, the back surface, or both sides. By heating, the original skin pack film 6P is softened.

  The softened original skin pack film 6P is moved downward together with the holding frame 99, and the original skin pack film 6P is placed on the surface of the original mount 1P. When the original skin pack film 6P that is sufficiently soft without being heated is used, the original skin pack film 6P may be directly covered on the base paper 1P without performing the heat treatment.

  FIG. 9 shows a state after the softened original skin pack film 6P is placed on the surface side of the original backing paper 1P so as to cover the article A to be packaged. In the cross-sectional view of FIG. 9, the original skin pack film 6 </ b> P does not represent the thickness but is indicated by a simple solid line (same for FIG. 11). As shown in FIG. 9, the original mount 1 </ b> P on which the packaged object A is placed is placed on the surface of the suction stand 9. Note that the original mount 1 </ b> P may be transferred to the surface of the suction table 9 after placing the article A to be packaged. However, since the article to be packaged A may be displaced during the transfer, it is preferable to place the original mount 1P on the surface of the suction table 9 before placing the article to be packaged A.

  The suction base 9 includes a base body 91, a closed space 92 (hollow part) formed in the base body 91, and a plurality of intake holes formed on the surface of the base body 91 and communicated with the closed space 92. 93 and a communication path 94 communicating the closed space 92 with the outside. A suction pipe (not shown) connected to the suction device is connected to the communication path 94. In addition, when FIG. 9 is seen, it seems that it is difficult for the surface of the base main body 91 to block | close the through-hole 5, and to attract | suck air from the through-hole 5. FIG. However, since the actual suction table 9 is formed with an infinite number of small air intake holes 93, the air between the base paper 1P and the original skin pack film 6P can be smoothly sucked from each through hole 5.

  Next, the original skin pack film 6P is adhered to the surface of the original mount 1P by sucking the original skin pack film 6P from the back side of the original mount 1P. As described above, the base paper 1P covered with the original skin pack film 6P is placed on the surface of the suction base 9 having a plurality of air intake holes 93. A suction device (not shown) connected to the suction tube is operated to vacuum-suck the base paper 1P. Then, the air between the base paper 1 </ b> P and the original skin pack film 6 </ b> P enters the suction hole 93 through each through hole 5, and is further sucked into the suction device through the closed space 92 and the communication path 94. The air suction direction is indicated by the white arrow in FIG.

  By sucking air, the original skin pack film 6P is drawn to the surface of the original mount 1P. The original skin pack film 6P extends along the outer shape of the article to be packaged A and is in close contact with the surface of the original mount 1P. Since the holding frame 99 that holds the periphery of the original skin pack film 6P is in airtight contact with the surface of the base body 91, external air is sucked from between the periphery of the original skin pack film 6P and the base body 91. You will not be drawn into 93.

  When the original skin pack film 6P is sucked to the front side of the original mount 1P, the back surface of the original skin pack film 6P starts to come into contact with the top of the convex portion 3. When the original skin pack film 6P comes into contact with the convex portion 3, the heat-sensitive adhesive constituting the convex portion 3 is activated by the heat and expresses adhesiveness. In addition, when using the original skin pack film 6P softened at room temperature (without heating), the heat-sensitive adhesive cannot be heated by the heat of the original skin pack film 6P. For this reason, before covering the original skin pack film 6P, it is necessary to heat the surface of the original backing paper 1P so that the heat-sensitive adhesive can be bonded. In addition, even when the original skin pack film 6P softened by heating is used, if the heat-sensitive adhesive cannot be sufficiently heated only by the heat of the film itself, the heat-sensitive adhesive is applied before the original skin pack film 6P is covered. It is preferable to heat the agent.

  The surface of the original mount 1P (skin pack mount 1) is formed in an uneven shape. For this reason, in the process in which the original skin pack film 6P is bonded to the original mount 1P, an air escape path configured between the recess 4 and the back surface of the original skin pack film 6P is secured (see FIG. 10). The air between the original backing paper 1P and the original skin pack film 6P is sucked from the through hole 5 (and the auxiliary through hole 7 provided as necessary) as described above. And since the said recessed part 4 is extended and provided in the edge part direction from the through-hole 5 (and auxiliary | assistant through-hole 7), the vicinity area | region of the said through-hole 5 (and auxiliary | assistant through-hole 7) at the initial stage of attraction | suction The surface of the original backing paper 1P and the original skin pack film 6P are not tightly adhered. Therefore, the air between the base paper 1P and the film 6P in the region away from the through hole 5 also passes through the concave portion 4 (passage) extending to the end of the base paper 1P. Collected and sucked into the hole 7).

  In accordance with the suction of the air, the original skin pack film 6P is pressed against the convex portion 3 and adheres to the convex portion 3, and finally, the back surface of the original skin pack film 6P comes into close contact with the surface of the concave portion 4. In this way, as shown in FIG. 11, a continuous body 100 is obtained in which the original skin pack film 6P is adhered to the surface of the original mount 1P with the package A interposed therebetween. The continuous body 100 is a continuous body of a plurality of skin pack packages 10.

Finally, the finishing process is performed. Specifically, the continuous body 100 obtained by the suction is removed from the holding frame 99. Then, as shown in FIG. 12, the said continuous body 100 is cut out along the external shape of each skin pack package 10. As shown in FIG. The cut line D is indicated by a thin dotted line in FIG.
The area other than the range surrounded by the cut line D is an ear region to be removed, and the auxiliary through hole 7 is included in the ear region.

  The cutting can be performed by punching using a punching die, cutting using a cutter, or the like. In this way, as shown in FIG. 13, the object A to be packaged is attached to a predetermined position of the mount, the skin pack film 6 is in close contact with the object A to be packaged, and the surface of the convex part 3 and the surface of the concave part 4 A plurality (for example, six) of the same skin pack package 10 adhered to at least one of the above can be obtained simultaneously. If necessary, a suspension hole may be formed in the skin pack package 10 (not shown).

  The skin pack mount 1 (original mount 1P) of the present invention is provided with a recess 4 on the surface of the substrate 2 extending from the through hole 5 in the end direction. By using such a skin pack mount 1 (original mount 1P), it is possible to obtain a skin pack package 10 in which the skin pack film 6 is adhered not only in the vicinity of the through-hole 5 but also to the end of the mount. Further, since the through hole 5 is formed in the base material 2 of the mount, the skin pack package 10 can be easily opened by breaking the base material 2 from the through hole 5. Since the through-hole 5 overlaps the planar projection shape of the article A to be packaged, the skin-pack package 10 can be obtained in which the through-hole 5 is not visible from the surface side of the skin pack package 10 and the appearance is good. . Further, when the skin pack mount 1 is used, the skin pack package 10 in which the skin pack film 6 is adhered to the peripheral end portion of the substrate 2 can be obtained. In the skin pack package 10, the edge of the skin pack film 6 is unlikely to be inadvertently rolled during the distribution process.

(Modification)
Next, a modification of the skin pack mount of the present invention will be described. In the following description of various modified examples, the same configurations and effects as those of the above-described embodiment (assuming that the description has been given) may be omitted, and terms and symbols may be used.

  In the said embodiment, although the surface of the convex part 3 can be adhere | attached with respect to a skin pack film, and the surface of the recessed part 4 cannot be adhere | attached with respect to a skin pack film, this invention is not limited to this. For example, (1) the surface of the concave portion 4 can be adhered to the skin pack film and the surface of the convex portion 3 cannot be adhered to the skin pack film, or (2) both the convex portion 3 and the concave portion 4 are skins. You may be comprised so that adhesion | attachment with respect to a pack film is possible.

  For example, as shown in FIG. 14A, the skin pack mount 1 as described in the above (1) is an area that is to be formed in an uneven shape on the entire surface of the base material 2 or on the surface of the base material 2. In addition, an adhesive material such as a heat-sensitive adhesive is provided in a solid shape to form the adhesive layer 81, and the convex portion 3 made of a non-adhesive material is provided on the surface of the adhesive layer 81. Of the surface of the adhesive layer 81, a portion where the convex portion 3 is not provided becomes the concave portion 4. In the present specification, the solid state means a so-called solid coating state (a state in which there is no gap).

  For example, as shown in FIGS. 14 (b) and 14 (c), the skin pack mount 1 as in the above (2) is formed in an uneven shape on the entire surface of the substrate 2 or the surface of the substrate 2. It is obtained by providing a solid adhesive material such as a heat-sensitive adhesive in a region to be formed, and forming the convex portion 3 and the concave portion 4 by forming the surface of the adhesive layer 82 in an irregular shape. As a method of forming the surface of the adhesive layer 82 in a concavo-convex shape, (i) an adhesive material is applied so as to produce concavo-convexity, and (ii) after forming the adhesive layer 82 having a substantially uniform thickness, Embossing is performed from the surface, or (iii) after forming the adhesive layer 82 having a substantially uniform thickness, a part of the adhesive layer 82 is scraped off from the surface of the adhesive layer 82 in the thickness direction of the adhesive layer 82. It is done. In FIG. 14B, the convex portion 3 has a columnar shape such as a cylindrical shape (the columnar shape is a circular shape, an elliptical shape, a polygonal shape, etc., and a cross-sectional shape is a rectangular shape or The case where it is formed in a square shape is illustrated. The top of the convex portion 3 is flat.

  Moreover, in the said embodiment, although the surface of the recessed part 4 is flat shape, as shown in FIG.14 (c), the surface of the recessed part 4 may be formed in the cross-sectional view substantially circular arc shape, for example. Such a recess 4 also has the effect of the present invention. But when the surface of the recessed part 4 is formed in cross-sectional view substantially circular arc shape, the boundary of the convex part 3 and the recessed part 4 may become indefinite. That is, the planar view shape of the convex part 3, the space | interval of the adjacent convex part 3, and the height of the convex part 3 may become unclear. In such a case, a plane including an intermediate point between the highest part of the convex part 3 and the lowest part of the concave part 4 is assumed, and a part protruding from the plane is regarded as the convex part 3, and Further, the recessed part is regarded as the recessed part 4.

  Furthermore, in the said embodiment, although the heat sensitive adhesive or the heat sensitive adhesive is illustrated as an adhesive material, it can replace with this and can also use a sealant film. The sealant film is a film that is non-adhesive at room temperature, and is a film that is melted by heat, pressure-bonded, and bonded to the other party by cooling. The sealant film is mainly composed of polyethylene resin such as low-density polyethylene, medium-density polyethylene, high-density polyethylene, linear low-density polyethylene, and ethylene-butene copolymer, and a tackifier is added as necessary. Film. For example, by using a sealant film as the adhesive layers 81 and 82 in FIGS. 14A, 14 </ b> B, and 14 </ b> C, the base 1 for skin pack having the uneven region on the surface of the substrate 2 is obtained. Can do.

In the said embodiment, although the uneven | corrugated area | region of a sea island structure is provided in the whole surface of the base material 2, this invention is not limited to this. This sea-island structure region may be provided on a part of the surface of the substrate 2. For example, as shown in FIGS. 15 and 16, the sea-island structure region may be provided in the in-plane center portion of the base material 2 including the through hole 5. In this case, it is necessary to provide an annular adhesive layer 83 in plan view on the peripheral edge of the base material 2 in order to prevent the edge of the adhered skin pack film from curling. In this case, as shown in FIG. 15, the region of the sea-island structure is surrounded by an adhesive layer 83 having an annular shape in plan view. Examples of the annular adhesive layer 83 in plan view include an adhesive convex portion as shown in FIG. 16 or an adhesive concave portion that is not particularly shown.
Since the skin pack mount 1 also has the recess 4 extending to the end of the base material 2, when the skin pack film is sucked, the skin pack film adheres to the mount in the uneven region of the sea-island structure. The peripheral edge of the skin pack film adheres to the adhesive layer 83 over the entire periphery of the peripheral edge of the mount.

  Moreover, in the said embodiment, although the contact bonding layer (convex part 3) is provided also in the area | region where the to-be-packaged goods A contact | connects when obtaining the skin pack package among the surfaces of the base material 2, It is good also as adhesion impossible about the area | region where the to-be-packaged object A touches among the surfaces. For example, in the area where the article to be packaged A is in contact, the adhesive convex portion 3 shown in the above embodiment may not be formed, and the area may be configured by the surface of the substrate 2 (not shown).

Moreover, in the said embodiment, although the area | region formed in uneven | corrugated shape is sea island structure, the area | region formed in uneven | corrugated shape is not restricted to the sea island structure which uses the recessed part 4 as the sea. For example, as shown in FIG. 17, a region formed in a concavo-convex shape is configured by alternately arranging the convex portions 3 in a plan view and the concave portions 4 in a plan view in the vertical direction (or the width direction). It may be. Also in this case, at least one recess 4 is formed so as to extend from the through hole 5 in the end direction.
Further, as shown in the figure, when the convex portions 3 and the concave portions 4 are provided in a stripe shape in the vertical direction, the concave portions 4 connected to the through holes 5 do not extend in the upper portion and the lower portion of the base material 2. There is a case. Therefore, it is preferable to provide the adhesive layer 84 in a solid form or a dot form in the upper part and the lower part. In addition, in FIG. 17, although the adhesive layer 84 provided in the upper part and the lower part of the base material 2 is represented as a convex part, if the upper part and the lower part of the base material 2 can be adhere | attached on a skin pack film, Since it is good, this portion may be a recess.

Further, as shown in FIG. 18, the convex portion 3 may be formed in a ring shape in plan view at the peripheral end portion of the surface of the substrate 2, and the other portion may be the concave portion 4.
This can be said to be obtained by omitting the sea-island structure region from the examples shown in FIGS. Specifically, a convex portion 3 having a ring shape in plan view is formed only at the peripheral end portion of the surface of the substrate 2, and the surface of the convex portion 3 can be adhered to the skin pack film. The width of the annular protrusion 3 is, for example, 5 mm to 15 mm, although it depends on the size of the mount.

  The concave portion 4 is formed in a range surrounded by the annular convex portion 3 shown in FIG. 18 and including the through hole 5. The surface of the recess 4 cannot be adhered to the skin pack film. The skin pack mount 1 of this modified example has a concavo-convex region consisting of one convex portion 3 and one concave portion 4 formed inside thereof on the surface of the base material 2. Since the skin pack mount 1 of this modified example is also provided with the recess 4 at the end of the base material 2, when the skin pack film is sucked, air can be sucked from the through hole 5 to the end of the base material 2. The peripheral end portion of the skin pack film adheres over the entire periphery of the peripheral end portion of the mount.

  In the said embodiment, although the aggregate | assembly of the through-hole 5 which comprised planar view substantially U shape was formed in the base material 2, the aggregate shape is not limited to substantially U shape. For example, as shown in FIG. 18, a plurality of through holes 5 may be formed in a substantially C shape in a plan view. Moreover, the through-hole 5 is not restricted to the case where it is formed in the position which overlaps with the planar projection shape of the to-be-packaged object A. For example, the through-hole 5 may be arranged so that a part of the through-hole 5 overlaps the planar projection shape, or the entire through-hole 5 does not overlap the planar projection shape.

  Further, another base material (hereinafter referred to as a sub base material) may be further laminated on the back surface of the base material 2 of the above embodiment. However, when the sub-base material is laminated, it is necessary not to inhibit the suction of the air on the front surface side of the base material 2 to the back surface side of the base material 2. That is, when a known adhesive is provided in a solid shape on the back surface of the base material 2 and the sub-base material is laminated and bonded, the through hole 5 is blocked by the adhesive on the back surface of the base material 2. The air between the skin pack film and the mount cannot be sucked. For this reason, when the sub-base material is laminated, the base material 2 and the sub-base material are adhered to each other by interposing an adhesive except for the through-hole 5 and the periphery of the back surface of the base material 2, and the sub-base material. As the material, a sheet having air permeability in the thickness direction may be used. Examples of the sheet having air permeability in the thickness direction include paper such as cardboard (uncoated paper), non-woven fabric, and a synthetic resin sheet having numerous fine holes.

  Moreover, when using the sub-base material which does not have air permeability in the thickness direction, an air passage connected to the through hole 5 is secured between the base material 2 and the sub-base material, and the air passage is formed at the edge of the base material 2. The base material 2 and the sub base material may be laminated and bonded so as to communicate with each other. For example, FIG. 19 shows an application pattern of an adhesive interposed between the base material 2 and the sub-base material having no air permeability when laminated and bonded. For convenience, the case where the adhesive is provided on the back surface of the substrate 2 is illustrated, but the same is true if the adhesive is provided on the surface of the sub-substrate. In FIG. 19, the white background portion is a portion where no adhesive is provided, and the shaded portion indicates a range X where the adhesive is provided.

  The part where the adhesive is not provided extends, for example, in a substantially cross shape, to the edge of the base material 2 around the through hole 5 of the base material 2 and its periphery. Since the base material 2 and the sub-base material are not bonded to each other at the place where the adhesive is not provided, an air passage is formed between the two. Since the part where the adhesive is not provided extends from the through hole 5 to the edge of the base material 2, when the base material 2 and the sub base material are laminated and bonded, the air passage is formed from the through hole 5. It extends to the edge of the substrate 2.

  The skin pack base sheet 1 having the base material 2 and the sub base material bonded with such an adhesive pattern is sucked from the back side of the sub base material after covering the skin pack film. The air between the mount and the skin pack film passes from the through hole 5 of the base material 2 through the air passage between the base material 2 and the sub-base material and exits from the edge of the base material 2. it can.

  The above embodiment and various modifications may be combined as appropriate, or may be changed as appropriate to constitute the skin pack mount and skin pack package of the present invention.
