Description

  The present invention relates to a blister package that can open and close a part of a sealing sheet and put a stored article in and out.

2. Description of the Related Art Conventionally, blister packs are known as forms for packaging pharmaceuticals, dry batteries, oral hygiene products, cosmetics, machine parts such as screws, foods such as candy, and various articles such as toys.
A blister package generally includes a cover member made of a molded product of a synthetic resin sheet and a sealing sheet. The cover member is formed with a storage recess for storing an article in a part thereof, and a flange portion is extended from an edge of the storage recess. The sealing sheet is bonded to the back surface of the flange portion so as to close the opening side of the storage recess.

  In addition, a package body in which a sealing sheet is attached to a flange portion of a cover member via an adhesive that exhibits adhesiveness at room temperature is also known. In such a package, a part of the sealing sheet is cut out along the sewing line to open the storage concave part, and after taking out the article from the storage concave part, the part of the cut off sealing sheet is again put in the original position by the adhesive. The housing recess can be closed by adhering.

For example, Patent Document 1 includes a blister package 2 in which a seal sheet 7 is bonded to a molded sheet 4 to individually seal the housing 6, and a cover case 3 that covers the blister package 2. A cover case in which an opening part 14 is formed for each part facing each other, a zipper-type sewing line 15 is formed in the opening part 14, and the inner surface of the opening part 14 and the seal sheet 7 are bonded together with a re-adhesive adhesive. A blister pack is disclosed.
The blister package with a cover case of Patent Document 1 can take out an article from the opened storage portion 6 by picking a part of the opening portion 14 and cutting it along the sewing machine line 15. Moreover, since the adhesive of the inner surface of the opening part 14 can be re-adhered, the accommodating part 6 can be resealed by the opening part 14 cut off.

However, even if a part of the sealing sheet attached via the adhesive is cut along the sewing line, the sealing sheet may not be cut along the sewing line.
Specifically, the sewing machine line is a line in which through holes are intermittently formed in a cutting direction, such as a through hole, a non-through part, a through hole, and a non-through part. When the wire is pulled out, the cutting line generated by the cutting may not move to the non-penetrating portion and the through hole adjacent to the non-penetrating portion, and may deviate from the through hole in the middle of the sewing machine wire.

As one of the causes, it is considered that the sealing sheet is strongly bonded to the flange portion through the adhesive. Therefore, it is considered that the sealing sheet can be cut along the sewing machine line by using the adhesive having low adhesiveness.
However, when a low-adhesive pressure-sensitive adhesive is used, there is a risk that the end of the sealing sheet will come into contact with foreign matter during storage and transportation. Furthermore, after a part of the sealing sheet is cut off and peeled off from the flange part, there is a problem that it is difficult to reattach the part to the flange part and it is difficult to reseal the storage recess.

JP 2001-46468 A

  An object of the present invention is to provide a blister package that can cut and peel a part of a sealing sheet so as not to deviate relatively from the sewing machine wire, and can re-seal a storage recess by a part of the peeled sealing sheet. .

The first blister package of the present invention includes a cover member having a storage recess and a flange portion extending from an edge of the storage recess and provided around the storage recess, and a surface to which the flange portion is attached And a sealing sheet that closes the opening side of the housing recess, and a sewing line is formed in the surface of the sealing sheet, and the sealing sheet covers the flange portion. Affixed to the affixing surface so as to be peelable and re-adherable, the sealing sheet is a base material, an adhesive layer laminated on one side of the base material and exhibiting adhesiveness at room temperature, and the adhesive layer A weakened layer that is laminated on one side and weakens the adhesiveness of the adhesive layer, the weakened layer is laminated in a region near the sewing machine line of the sealing sheet, and the flange portion of the sealing sheet The sewing machine to which the area where the sewing wire is formed is affixed A flange portion corresponding to a flange portion to which a region including a sheet curl start edge is affixed and located on one side of the flange portion corresponding to the sewing machine. The adhesion strength of the flange portion corresponding to the sewing machine and the flange portion corresponding to the turning satisfies the following relationship.
Adhesion strength between the sealing sheet and the surface to be bonded of the flanged flange portion> Adhesive strength between the region near the sewing machine wire of the sealing sheet and the surface to be bonded of the sewing machine corresponding flange portion.
For example, the area near the machine line of the sealing sheet may be weakly attached to the surface to be bonded of the flange corresponding to the sewing machine, or the area near the machine line and the surface to be bonded of the flange corresponding to the sewing machine may be It may be non-adhesive.

  In the blister package of the present invention, the adhesion strength between the sealing sheet and the surface to be bonded of the flanged flange portion is between the area near the sewing line of the sealing sheet and the surface to be bonded of the sewing machine flange portion. Greater than adhesion strength. Such a blister package is hard to peel off the sealing sheet from the flange portion corresponding to turning during storage and transportation, and once the sealing sheet is artificially peeled off from the starting edge of the sheet turning, the sewing wire A part of the sealing sheet can be easily cut out along the sewing line without causing the vicinity region to be easily separated from the sewing machine-corresponding flange portion and relatively deviating from the sewing machine line. Moreover, a housing recessed part can also be resealed firmly by pasting together a part of peeled sealing sheet as it was.

In the first blister package of the present invention, the region other than the region near the sewing machine line of the sealing sheet adheres relatively strongly to the surface to be bonded of the flange portion corresponding to the sewing machine via the adhesive layer. The area near the sewing machine line of the sealing sheet is relatively weakly attached or non-adhered to the surface to be bonded of the flange portion corresponding to the sewing machine via the weakening layer. For this reason, it is possible to easily cut a part of the sealing sheet along the sewing line without relatively deviating from the sewing machine line. Can be resealed firmly.

In a preferable blister package of the present invention, the surface to be adhered of the flange portion corresponding to the sewing machine is a surface that is difficult to adhere.
Such a preferable blister package can easily peel off the sealing sheet.

  In a preferable blister package of the present invention, the flange portion further includes a lower corresponding flange portion to which a lower region of the sealing sheet is pasted, and a surface to be pasted of the lower corresponding flange portion is a difficult adhesion surface. The lower region of the sealing sheet that is affixed to the adherend surface of the lower corresponding flange portion is an adhesive surface with one surface of the adhesive layer exposed.

  Such a preferable blister package is because the adhesive surface in the lower region of the sealing sheet adheres to the surface to be applied (hard-to-adhere surface) of the lower corresponding flange portion, so that the lower region of the sealing sheet can be stably adhered, Further, when a part of the sealing sheet is peeled, the lower region is also peeled relatively easily.

The second blister package of the present invention includes a cover member having a storage recess and a flange portion extending from an edge of the storage recess and provided around the storage recess, and a surface to which the flange portion is attached And a sealing sheet that closes the opening side of the housing recess, and a sewing line is formed in the surface of the sealing sheet, and the sealing sheet covers the flange portion. Affixed to the affixing surface so as to be peelable and re-adherable, and the flange part includes a sewing machine-compatible flange part to which a region where a sewing machine line is formed of the sealing sheet is attached, and the sewing machine-compatible flange part. A flange-supporting flange portion that is located on one side and includes a region including a sheet-rolling start edge of the sealing sheet, and covers the sewing machine-compatible flange portion and the winding-compatible flange portion of the sealing sheet. Pasted Adhesion strength to the surface meets the following relationship.
Adhesion strength between the adhesion strength> a landing surface of the sealing perforation line region near other areas and perforations corresponding flange portion of the seat between the target application surface of the corresponding flange portion before the the Kifutome sheet turning> Adhesion strength between the area near the sewing machine line of the sealing sheet and the adherend surface of the sewing machine corresponding flange part .

In the second blister package of the present invention, the adhesion strength between the area other than the area near the sewing machine line of the sealing sheet and the adherend surface of the sewing machine corresponding flange part is the same as the adhesion strength of the turnable flange part and the sewing machine. This is the middle of the adhesion strength of the flange. For this reason, when a part of the peeled sealing sheet is attached to the flange portion again, it is possible to reliably prevent the sealing sheet from being carelessly peeled off. In other words, in the present invention, in order to cut the sealing sheet along the sewing line, the adhesion strength of the flange corresponding to the sewing machine in the vicinity of the sewing machine line is reduced or the adhesion strength is zero ( However, when a part of the peeled sealing sheet is pasted on the flange portion again, the sealing sheet and the sewing machine corresponding flange portion in that region cannot be sufficiently pasted. In this regard, the adhesion strength between the area other than the area near the sewing machine line of the sealing sheet and the surface to be bonded of the sewing machine-corresponding flange part is determined as By making it larger than the adhesion strength between them, when a part of the peeled sealing sheet is affixed to the flange portion again, the housing recess can be reliably resealed by a part of the sealing sheet without peeling both of them.

  The blister package of the present invention has a function that the sealing sheet has a function that it is difficult to inadvertently peel off from the corresponding flange portion, and a part of the sealing sheet can be cut and peeled so as not to deviate relatively from the sewing machine wire. In addition, a part of the peeled sealing sheet can be returned to its original position, and the housing recess can be resealed.

In FIG. 1 thru | or FIG. 5, the blister package 1 has the cover member 4 which has the accommodation recessed part 2 and the flange part 3, and the sealing sheet 5 which obstruct | occludes the opening side of the said accommodation recessed part 2. In FIG. A sewing line 6 is formed in the surface of the sealing sheet 5.
The cover member 4 is formed with a storage recess 2, and a flange portion 3 extends from the edge of the storage recess 2.
The storage recess 2 is a concave space for storing articles. One cover recess 2 may be formed in the cover member 4, or two or more store recesses 2 may be formed.
When the cover member 4 has two or more storage recesses 2, the storage recesses 2 are formed at predetermined intervals.

In the present embodiment, as shown in FIG. 6, the cover member 4 is formed with three storage recesses 2. The three storage recesses 2 are arranged side by side at a predetermined interval in the vertical direction and are independent of each other. Hereinafter, when the three storage recesses 2 are described separately, they are referred to as a first storage recess 21, a second storage recess 22, and a third storage recess 23 in order from the top.
The storage recesses 21, 22, and 23 are regularly arranged in the vertical direction, but may be irregularly arranged.
In addition, the code | symbol 4a is the substantially V-shaped notch carved in the thickness direction of the flange part 3 between the 1st accommodation recessed part 21 and the 2nd accommodation recessed part 22, and the 2nd accommodation recessed part 22 and the 3rd accommodation recessed part 23. Part.
The blister package 1 of the present invention cuts a part of the sealing sheet 5 along the sewing machine line 6 and completely peels it off from the cover member 4, and then uses the cut portion 4 a to make 1 of the cover member 4. The two storage recesses 2 can also be divided.

Each storage recess 2 has a front wall and a peripheral wall extending substantially orthogonally to the front wall from the peripheral edge of the front wall, and is surrounded by the edge of the peripheral wall. An opening for taking in and out the article is formed in the part.
The shape of the storage recess 2 is not particularly limited, and can be appropriately designed according to the shape of the article. In the present embodiment, the front wall of each storage recess 2 is formed in a substantially rectangular shape in front view, and the opening of each storage recess 2 is similarly formed in a substantially rectangular shape in front view. Accordingly, the peripheral wall of each storage recess 2 has a pair of side walls extending substantially orthogonal to the front wall from the left and right side edges of the front wall, and the upper and lower edges of the front wall from the front wall. And upper and lower walls extending substantially orthogonal to each other.
In this specification, the front view shape refers to a shape when viewed from a direction orthogonal to one surface of the sealing sheet 5.

Furthermore, the flange part 3 is extended outside from the edge (edge edge of a surrounding surface wall) of each storage recessed part 2. As shown in FIG.
The flange portion 3 is a portion that constitutes a surface to which the sealing sheet 5 is attached, and is also a portion that partitions the first storage recess 21, the second storage recess 22, and the third storage recess 23.
The flange portion 3 extends from the entire four sides of each storage recess 2.
Hereinafter, the flange portions 3 provided on the four sides of the storage recess 2 are referred to as first to fourth flange portions 31, 32, 33, and 34 (the flange portion 3 is provided in order on the four sides of the storage recess 2. (It is a generic term for the fourth flange portions 31, 32, 33, 34). For convenience, the first flange portion 31, the second flange portion 32, and the third flange portion are assumed to be counterclockwise as viewed from the front of the blister package of FIG. 33 and the fourth flange portion 34.

As seen from the front of the blister package as shown in FIG. 1, the first flange portion 31 extends outward from the left edge of the peripheral wall of the storage recess 2, and the second flange portion 32 extends around the storage recess 2. The third flange portion 33 extends outward from the right edge of the peripheral wall of the storage recess 2, and the fourth flange portion 34 extends to the upper end of the peripheral wall of the storage recess 2. It extends outward from the edge. The first flange portion 31 and the third flange portion 33 face each other, and the second flange portion 32 and the fourth flange portion 34 face each other.
The first to fourth flange portions 34 are all extended in the same plane.

In the present embodiment, three storage recesses 2 are formed. The first to fourth flange portions 31, 32, 33, and 34 are formed in the four directions of the first to third storage recesses 21, 22, and 23, respectively.
However, since the first storage recess 21 and the second storage recess 22 and the second storage recess 22 and the third storage recess 23 are arranged next to each other vertically, the first storage recess 21 and the second storage recess Each second flange portion 32 extending from the lower end edge of 22 is also used as each fourth flange portion 34 extending from the upper end edge of the second storage recess 22 and the third storage recess 23.
Further, the upper end edge of the fourth flange portion 34 extending from the upper end edge of the first storage recess 21 (uppermost storage recess) and the lower end edge of the third storage recess 23 (lowermost storage recess) are extended. The lower edge of the provided second flange portion 32 constitutes the periphery of the flange portion 3 of the cover member 4.

In addition, the 2nd flange part 32 extended from the lower end edge of the 3rd accommodation recessed part 23 (lowermost accommodation recessed part) is corresponded to the downward corresponding | compatible flange part C to which the lower area | region of a sealing sheet is affixed.
The lower corresponding flange portion C is provided to face the fourth flange portion 34 which is the sewing machine corresponding flange portion A with the third storage recess 23 interposed therebetween.

  In the present embodiment, the first flange portion 31 and the third flange portion 33 extend in a strip shape substantially in parallel, and the second flange portion 32 and the fourth flange portion 34 also extend in a strip shape substantially in parallel. In the present embodiment, the first flange portion 31 and the third flange portion 33 extend in a direction substantially orthogonal to the second flange portion 32 and the fourth flange portion 34.

The widths of the first to fourth flange portions 31, 32, 33, and 34 are not particularly limited, but if they are too short, the sealing sheet 5 may not be sufficiently pasted. From this viewpoint, the width of each of the first to fourth flange portions 31, 32, 33, 34 is preferably 2 mm or more, and more preferably 3 mm or more. In particular, the second flange portion 32 which is a flange portion corresponding to the sewing machine and also serves as the adjacent fourth flange portion 34 is preferably 3 mm or more, and more preferably 5 mm or more.
In addition, the width | variety of the 1st thru | or 4th flange parts 31, 32, 33, 34 says the length in the direction orthogonal to the direction where these flange parts are extended. If the width of the first to fourth flange portions 31, 32, 33, 34 is not constant in the extending direction, the width of the first to fourth flange portions 31, 32, 33, 34 is the smallest portion. Say length.

Each one surface of the first to fourth flange portions 31, 32, 33, 34 (surface opposite to the surface from which the housing recess 2 protrudes) is a surface to be bonded to which the sealing sheet 5 is to be bonded. is there.
In this embodiment, the area | region in which the sewing machine line 6 was formed among the sticking surfaces of the sealing sheet 5 sticks to each to-be-sticked surface of the 2nd flange part 32 of the 1st accommodating recessed part 21, and the 4th flange part 34. Is done. Similarly, the area where the sewing machine line 6 is formed is affixed to each application surface of the second flange portion 32 and the fourth flange portion 34 of the second storage recess 22, and the second flange portion 32 of the third storage recess 23. And it affixes on each to-be-applied surface of the 4th flange part 34. FIG. In the present embodiment, the second flange portion 32 and the fourth flange portion 34 extending from the upper and lower edges of each of the storage recesses 2 correspond to the sewing machine corresponding flange portion A.

  In each storage recess 2, the first flange portion 31 is located on one side of the second flange portion 32 and the fourth flange portion 34, and the third flange portion 33 is the second flange portion 32 and the fourth flange portion 34. It is located on the other side of the flange portion 34. In this embodiment, the sealing sheet 5 is affixed to the to-be-bonded surface of the flange part 3 so that a part of the sealing sheet 5 is scraped off from the 1st flange part 31 side. For this reason, the 1st flange part 31 is equivalent to the turning corresponding flange part B.

The adherend surfaces of the first to fourth flange portions 31, 32, 33, and 34 may be composed of surfaces having the same properties and surface shapes.
Preferably, the surface to be bonded of the first flange portion 31 and the surface to be bonded of the third flange portion 33 are both surfaces made of a material for forming the cover member and are flat surfaces. The to-be-bonded surface of a certain 2nd flange part 32 and the 4th flange part 34 is made into the surface which has difficulty adhesion. In the present embodiment, the second flange portion 32 extending from the lower end edge of the third storage recess 23 (the lowermost storage recess) is not a sewing machine-compatible flange but a downward-corresponding flange C. The second flange portion 32 is also a surface having difficulty adhesion.

Examples of means for making the adherend surfaces of the second flange portion 32 and the fourth flange portion 34 difficultly sticking surfaces include (1) wax on the surfaces of the second flange portion 32 and the fourth flange portion 34, Forming a coating layer containing an easy-release agent such as a lubricant and silicone; (2) forming the surface of the second flange portion 32 and the fourth flange portion 34 in an uneven shape (the surface to be applied is an uneven surface) To do).
Since the adherend surfaces of the second flange portion 32 and the fourth flange portion 34 are hard-to-adhere surfaces, the seal against the adherend surface of the sewing machine corresponding flange portion A cooperates with a weakening layer described later. The adhesion strength of the stop sheet 5 can be in a predetermined relationship.

In addition, the adhesive surface of the adhesive layer of the sealing sheet 5 is affixed to the second flange portion 32 extending from the third housing recess 23 which is the downward corresponding flange portion C.
In this embodiment, the to-be-attached surface of the first flange portion 31 and the to-be-attached surface of the third flange portion 33 are both flat surfaces, and the second flange portion 32 and the fourth flange that are sewing machine-corresponding flange portions A. The surface to be bonded of the flange portion 34 is an uneven surface.
In FIG. 6, the range where the uneven surface is formed is shown by light ink painting, and in FIG. 5, the details of the uneven surface are shown in cross section.

The irregular surface is a surface on which a plurality of fine convex portions and concave portions are regularly or randomly formed. When a known pressure-sensitive adhesive tape is affixed to the uneven surface, a slight gap may be formed between the surface of the adhesive tape and the concave portion of the uneven surface. Therefore, the concavo-convex surface has a difficult adhesion property that a general adhesive surface is less likely to adhere as compared to a flat surface.
For example, when a known pressure-sensitive adhesive tape is applied to the uneven surface, the adhesion area of the pressure-sensitive adhesive tape is 20% to 80%, preferably 30% to 70%.
The said adhesion area is calculated | required by {(Area of an adhesive tape-The area which is not adhering to an uneven surface among adhesive tapes) / Area of an adhesive tape} * 100.

Although the whole to-be-bonded surface of the said 2nd flange part 32 and the said 4th flange part 34 may be made into an uneven surface (namely, difficult-to-adhere surface), it prevents the sealing sheet 5 from being carelessly peeled off. Therefore, it is preferable that the uneven surface is formed in a range excluding each corner portion intersecting the first flange portion 31 and the third flange portion 33 in the second flange portion 32 and the fourth flange portion 34. . That is, an uneven surface is not formed on the adherend surface of the flange-supporting flange portion B, and a general adhesive surface is more likely to adhere to the adherend surface of the turn-supporting flange portion B than a difficult-to-adhere surface. A surface (for example, a flat surface) is preferable.
The second flange portion 32 extended from the lower end edge of the third storage recess 23 (lowermost storage recess) is also formed with an uneven surface except for both corners.

The method for forming the uneven surface is not particularly limited, and examples thereof include embossing and adhesion of fine particles.
The adhesion of the fine particles is a method of forming an uneven surface by attaching inorganic fine particles such as silica and titanium oxide to one surface of the second flange portion 32 and the fourth flange portion 34.
Embossing is preferable because an uneven surface can be formed when the cover member 4 is molded.

The material of the cover member 4 is not particularly limited, and examples thereof include synthetic resins such as polyethylene terephthalate, polyvinyl chloride, polypropylene, and polystyrene. The cover member 4 is preferably transparent or translucent in order to see through the stored article, but a non-transparent material may be used.
The cover member 4 can be formed by an injection molding method, but is usually formed by a sheet molding method. Examples of the sheet used in the sheet forming method include a synthetic resin sheet and a laminated sheet in which a plurality of synthetic resin sheets are laminated.
The cover member 4 has a thickness of 0.1 to 2 mm, preferably 0.2 to 1 mm.

Next, the sealing sheet 5 is affixed to the adherend surface of the flange portion 3 in order to close the opening of each storage recess 2.
The sealing sheet 5 covering each storage recess 2 can be divided according to a sewing line 6 formed in the surface thereof.

As shown in FIGS. 7 to 9, the sealing sheet 5 is laminated on a base material 51, an adhesive layer 52 laminated on one surface of the base material 51, and a part of one surface of the adhesive layer 52. The layer structure has a weakening layer 53 and a concealing layer 54 laminated on the other part of one surface of the adhesive layer 52.
In FIG. 7, for easy understanding, the area where one surface of the adhesive layer 52 is exposed is shaded, the area where one surface of the weakening layer 53 is exposed is vertical stripes, and the one surface of the concealing layer 54 is The exposed range is indicated by light ink painting, and the exposed range of one side of the substrate 51 is indicated by a solid color.

The adhesive layer 52 is a layer made of an adhesive that exhibits adhesiveness at room temperature.
The weakening layer 53 is a layer for weakening the adhesiveness of one surface of the adhesive layer 52 (the surface opposite to the surface laminated on the base material). Hereinafter, one surface of the adhesive layer 52 may be referred to as an adhesive surface.
The concealing layer 54 is a layer for substantially concealing the adhesiveness of the adhesive surface of the adhesive layer 52.
The adhesive surface exhibits adhesiveness at room temperature, and can be releasably attached to the surface to be applied of the flange portion 3 and can be reapplied after peeling.

The substrate 51 is not particularly limited, and various sheets such as synthetic paper, synthetic resin films, paper, laminated sheets thereof, laminated sheets obtained by laminating other functional layers such as a metal vapor deposition layer on these sheets, and the like. Can be used.
Preferably, as the substrate 51, synthetic paper, a synthetic resin film, or a laminated sheet thereof is used.
Although the thickness of the base material 51 is not specifically limited, It is 0.05 mm-1.0 mm, Preferably it is 0.1 mm-0.5 mm.

The front view shape of the substrate 51 is not particularly limited, and can be formed in an appropriate shape. In this embodiment, the base material 51 is formed in a substantially rectangular shape when viewed from the front so that the peripheral edge of the sealing sheet 5 and the peripheral edge of the flange portion 3 of the cover member 4 substantially coincide with each other.
When the sealing sheet 5 is affixed to the flange portion 3 of the cover member 4, it is an area of the base material 51 that faces the sewing machine corresponding flange portion A, and does not overlap the edge of the storage recess 2. The sewing machine wire 6 is formed at a position having a distance from (the entire sewing machine wire 6 is formed facing the flange portion 3).

In the present embodiment, three sewing lines 6 extending in the left-right direction are formed at intervals in the vertical direction. Specifically, the region of the base 51 corresponding to the fourth flange portion 34 of the first storage recess 21, the second flange portion 32 of the first storage recess 21 (the fourth flange portion 34 of the second storage recess 22). And the region corresponding to the second flange portion 32 of the second storage recess 22 (the fourth flange portion 34 of the third storage recess 23) are respectively formed on the sewing wire 6.
The sewing machine line 6 is not formed in the region (the lower region of the sealing sheet 5) pasted on the surface to be pasted of the second flange portion 32 of the third storage recess 23.

  Each sewing line 6 is formed substantially parallel to the direction in which the sewing machine corresponding flange portion A extends from one side edge to the other side edge of the substrate 51 (sealing sheet 5). Accordingly, each sewing machine line 6 extends in a direction substantially orthogonal to the direction in which one side edge of the base material 51 extends. When the sealing sheet 5 on which the sewing machine line 6 is formed is pasted on the cover member 4, the sewing machine line 6 extends substantially orthogonally to the direction in which the turnable flange portion B extends.

  Each sewing line 6 is a line in which through-holes penetrating in the thickness direction of the substrate 51 and non-penetrating portions that do not penetrate the substrate 51 are alternately arranged. The front view shape of the through hole is not particularly limited, and examples thereof include a circular shape, an elliptical shape, a polygonal shape such as a triangle, a straight shape, a substantially V shape, and a substantially Y shape. In the illustrated example, each through hole of the sewing machine wire 6 is substantially Y-shaped.

The pressure-sensitive adhesive layer 52 can be formed by applying a substantially solid pressure-sensitive adhesive (pressure-sensitive pressure-sensitive adhesive) that exhibits adhesiveness at room temperature to substantially the entire one surface of the substrate 51. The substantially solid shape includes a lattice shape, a mesh shape, a shape in which an infinite number of points are gathered, and the like.
However, in the present embodiment, the adhesive layer 52 is not formed in the belt-like region in the vertical direction at the one end portion of the base material 51. One side end portion of the base material 51 (sealing sheet 5) is a portion corresponding to the edge portion of the flange corresponding flange portion B of each storage recess 2.
The thickness of the adhesive layer 52 is about 3 μm to 50 μm, preferably about 10 μm to 30 μm.

As the form of the pressure-sensitive adhesive, solvent-based, solvent-free system, water-based, hot-melt system (this hot-melt system refers to a pressure-sensitive adhesive in a form showing adhesiveness at normal temperature after being heated and applied), UV system etc. are mentioned.
The peel strength of the adhesive surface of the adhesive layer 52 is preferably 3 to 20 N / 25 mm, and more preferably 5 to 15 N / 25 mm.
The peel strength of the adhesive surface is a value measured by a method according to JIS Z 0237 180 degree peel. Specifically, a synthetic resin film (test piece) on which the adhesive layer 52 is formed is formed to a size of 100 mm × 25 mm, and this is attached to an adherend made of polyethylene terephthalate, and tested at 180 degrees at a speed of 300 mm / min. The maximum stress value when the specimen is pulled and the specimen is peeled off.

The weakening layer 53 is a layer for weakening the adhesiveness of the adhesive surface of the adhesive layer 52 or concealing the adhesiveness of the adhesive surface. One surface of the weakened layer 53 (the surface opposite to the surface laminated on the adhesive surface) has adhesiveness, but the peel strength is weaker than the adhesive surface or does not exhibit adhesiveness. Hereinafter, one surface of the weakened layer 53 may be referred to as a weakened surface.
Preferably, the weakened layer 53 is a layer that weakens the adhesiveness of the adhesive surface of the adhesive layer 52, and the weakened surface has adhesiveness, but the peel strength is weaker than the adhesive surface.
When the weakened layer 53 conceals the adhesiveness of the adhesive surface, the weakened surface has substantially no adhesiveness.
When the weakened layer 53 weakens the adhesiveness of the adhesive surface, the peel strength of the weakened surface is preferably more than 0 times and less than 0.8 times the peel strength of the adhesive surface. 1 to 0.75 times is more preferable, and 0.3 to 0.7 times is particularly preferable.
The peel strength of the weakened surface of the weakened layer 53 can be measured in the same manner as the peel strength of the adhesive surface.

The weakening layer 53 is laminated on the adhesive surface in the vicinity of the sewing machine line of the sealing sheet 5. Specifically, the weakening layer 53 is laminated on a belt-like region having a predetermined width including the sewing machine line 6 on the adhesive surface. In other words, the sewing machine line 6 is formed in a range where the weakening layer 53 is provided. The width of the weakening layer 53 (in this embodiment, the width is the length in the vertical direction; the same applies hereinafter) exceeds the width of the sewing machine wire 6 and is shorter than the width of the sewing machine corresponding flange portion A.
In addition, in the area | region (lower area | region of the sealing sheet 5) affixed on the to-be-adhered surface of the downward corresponding flange part C, the said weakening layer 53 is not provided but the adhesive surface of the adhesion layer is exposed.

When the sealing sheet 5 is affixed to the flange portion 3 of the cover member 4, the weakening layer 53 is a sewing machine so that an adhesive surface is formed in a band shape between the edge of each storage recess 2 and the edge of the weakening layer 53. It is formed shorter than the width of the corresponding flange portion A.
The width of the weakening layer 53 is, for example, about 1 mm to 7 mm, preferably 2 mm to 5 mm, although it depends on the width of the flange A for the sewing machine.

The weakening layer 53 is formed, for example, by applying a masking agent to one surface of the adhesive layer 52. As the masking agent, for example, an ultraviolet curable ink containing an ultraviolet curable resin can be used.
By appropriately adjusting the type, coating area, and coating thickness of the masking agent, it is possible to form a weakened surface that has adhesiveness but has a weaker peel strength than the adhesive surface or does not have adhesiveness.
For example, when a masking agent such as ultraviolet curable ink is applied, the application area is preferably 20% to 100%, more preferably 25% to 90%, and particularly preferably 30% to 70%. The thickness is preferably 0.2 μm to 3.0 μm. By setting the formation area and thickness of the weakened layer 53 in such a range, a weakened surface having a peel strength in the above range can be formed.

The concealing layer 54 is a layer for substantially concealing the adhesiveness of one surface of the adhesive layer 52.
Therefore, one surface of the masking layer 54 is a non-adhesive surface that does not adhere to the cover member 4 or the article. Hereinafter, one surface of the masking layer 54 may be referred to as a non-adhesive surface.
The concealing layer 54 is provided in a region corresponding to the opening of each storage recess 2 when the sealing sheet 5 is attached to the cover member 4. In the present embodiment, three concealing layers 54 are provided corresponding to the regions surrounded by the edges of the peripheral walls of the first storage recess 21, the second storage recess 22 and the third storage recess 23.
Therefore, it is possible to prevent the article stored in the storage recess 2 from adhering to the sealing sheet 5 when the opening of each storage recess 2 is closed by the sealing sheet 5.

  Between the edge of the masking layer 54 (non-adhesive surface) and the edge of the weakened layer 53 (weakened surface), the adhesive surface is exposed in a band shape.

The masking layer 54 is formed, for example, by sticking a thin synthetic resin film on one surface of the adhesive layer 52.
By sticking a thin synthetic resin film on the adhesive surface, the area where the concealing layer 54 is provided can be made non-adhesive without causing the adhesive to ooze out.
As a method for forming the masking layer 54, a method of applying the masking agent to the masking layer forming region in a thick shape may be employed. For example, by applying the masking agent to a thickness of about 5 μm to 30 μm, the concealing layer 54 that conceals the adhesiveness of the adhesive surface at the applied portion can be formed.

  In addition, the upper part of the cover member 4 and the sealing sheet 5 is provided with a suspension hole 55 penetrating them.

The blister package 1 of the present invention is obtained by putting a desired article into each housing recess 2 of the cover member 4 and sticking the sealing sheet 5 on the surface to be stuck of the flange portion 3 of the cover member 4.
In the blister package 1 of the present invention, the opening of each storage recess 2 is closed by a sealing sheet 5. In addition, since the non-adhesive surface of the sealing sheet 5 faces the opening of each storage recess 2, the stored article does not adhere to the sealing sheet 5.

The weakened surface of the sealing sheet 5 is affixed to the sewing machine corresponding flange portion A which is an uneven surface.
The adhesive surface of the sealing sheet 5 corresponds to the sewing machine except for the flange part 3 other than the sewing machine-compatible flange part A including the turn-supporting flange part B, and the part of the sewing machine-compatible flange part A to which the weakened surface is affixed. Affixed to the flange portion A.
Accordingly, both the weakened surface and the adhesive surface of the sealing sheet 5 are attached to the sewing machine corresponding flange portion A which is an uneven surface.
The flange portion other than the sewing machine corresponding flange portion A includes the lower corresponding flange portion C.

The adhesion strength between the uneven surface and the weakened surface is smaller than the adhesion strength between both surfaces when the weakened surface is stuck on a flat surface.
Similarly, the adhesion strength between the uneven surface and the adhesive surface is smaller than the adhesion strength between both surfaces when the adhesive surface is stuck on a flat surface.

For this reason, as for the blister package 1 of this invention, the adhesion strength with respect to the to-be-bonded surface of the said flange part A and the flange part B corresponding to the sewing machine of the sealing sheet 5 satisfy | fills the following relational expression X.
Relational expression X: Adhesion strength between the sealing sheet 5 and the surface to be bonded of the flange portion B for bending> Adhesion strength between the region near the sewing line of the sealing sheet 5 and the surface to be bonded to the flange portion A for sewing .
Preferably, the following relational expression Y is satisfied.
Relational expression Y: Adhesion strength between the sealing sheet 5 and the adherend surface of the flange portion B corresponding to bending (hereinafter referred to as adhesion strength (1))> Area other than the vicinity of the sewing machine wire in the sealing sheet 5 and the sewing machine correspondence Adhesion strength between the surface of the flange A and the surface to be adhered (hereinafter referred to as adhesion strength (2))> Adhesion strength between the region near the sewing machine wire of the sealing sheet 5 and the surface to be adhered of the flange A corresponding to the sewing machine ( Hereinafter, adhesion strength (3)).
The difference in adhesion strength can be determined by the difficulty in peeling off when the sealing sheet 5 is peeled 180 degrees.
The adhesion strength (2) includes the adhesion strength between the lower region of the sealing sheet 5 and the adherend surface of the lower corresponding flange portion C.

The adhesion strength between the sealing sheet 5 and the adherend surface of the flanged flange portion B is preferably 3 to 20 N / 25 mm, and more preferably 5 to 15 N / 25 mm.
The adhesion strength between the region other than the region near the sewing machine line of the sealing sheet 5 and the adherend surface of the sewing machine corresponding flange portion A is preferably 1 to 12 N / 25 mm, and more preferably 3 to 9 N / 25 mm. preferable.

The adhesion strength between the area near the sewing machine wire of the sealing sheet 5 and the surface to be bonded of the sewing machine corresponding flange part A is preferably 0 to 8 N / 25 mm, and more preferably 0.3 to 5 N / 25 mm. . The adhesion strength of 0 means that the vicinity of the machine line of the sealing sheet 5 and the surface to be bonded of the sewing machine corresponding flange portion A are not bonded.
These adhesion strengths are values measured by a method according to JIS Z 0237 180 degree peeling. Specifically, the sealing sheet 5 (test piece) to be tested is formed to 100 mm × 25 mm, and this is attached to the flange portion 3 to be tested, and the test piece is pulled to 180 degrees at a speed of 300 mm / min. The maximum stress value when the test piece is peeled off. When a test piece having a width of 25 mm cannot be prepared at the time of measurement, measurement is performed using a test piece as close to 25 mm as possible, and the result is converted to a width of 25 mm.

The blister package 1 of the present invention can open the opening of the housing recess 2 by peeling off a part of the sealing sheet 5 from the sheet curl start edge 5a of the sealing sheet 5.
The adhesive layer 52 is not provided in the belt-like region at the one side end of the sealing sheet 5, and the flange portion B (first flange portion 31) between the one side end of the sealing sheet 5 and each storage recess 2. ) Is non-adhesive, so that the sheet curl start edge 5a of the sealing sheet 5 can be easily picked and a part of the sealing sheet 5 can be peeled off.

When the sheet winding start edge 5a of a part of the sealing sheet 5 such as the sheet winding start edge 5a of the sealing sheet 5 corresponding to the first storage recess 21 is picked and pulled, the sealing sheet 5 is moved along the sewing machine line 6. Start cutting. Then, a part of the sealing surface of the sealing sheet 5 corresponding to the first storage recess 21 defined by the sewing machine wire 6 is peeled off from the surface to be bonded of the corresponding flange portion B (first flange portion 31). Simultaneously with the cutting along the line 6, the region near the sewing line of the sealing sheet 5 and the region other than that region between the edge of the first storage recess 21 and the edge of the region near the sewing line are Then, it is peeled from the sewing machine corresponding flange part A.
In this way, by separating a part of the sealing sheet 5, it is possible to open the storage recess 2 and put in and out the article. Moreover, the storage recessed part 2 can be resealed firmly by reattaching each part of the peeling sealing sheet 5 to each flange part 3 as it was.

  When the third storage recess 23 (lowermost storage recess) is opened, a part of the sealing sheet 5 is formed along the corresponding sewing line 6 between the second storage recess 22 and the third storage recess 23. Cut out. As described above, since the second flange portion 32 (downward corresponding flange portion C) extending from the lower end edge of the third storage recess 23 is a hard-to-adhere surface, the lower region of the sealing sheet 5 is also It peels relatively easily from the lower corresponding flange C.

The blister package 1 of the present invention has the strongest adhesion between the sealing sheet 5 and the surface to be bonded of the turnable flange portion B in relation to the adhesion strength (1) to the adhesion strength (3). For this reason, it is possible to prevent the sealing sheet 5 from being inadvertently peeled off during storage / transportation of the blister package 1, and a part of the sealing sheet 5 can be firmly sealed after resealing.
In addition, also in the relationship between the lower region of the sealing sheet 5 and the lower corresponding flange portion C, the lower region of the sealing sheet 5 can be prevented from being inadvertently peeled off. Can be tightly sealed.
In particular, in the blister package 1, the sealing sheet 5 is also most strongly attached to the surface to be bonded of the third flange portion 33 that faces the first flange portion 31 that is the flange portion B for turning. Yes. For this reason, inadvertent peeling of the sealing sheet 5 can be reliably prevented.

  Further, the blister package 1 has the weakest area between the vicinity of the sewing machine wire of the sealing sheet 5 and the surface to be bonded of the sewing machine corresponding flange portion A in relation to the adhesion strength (1) to the adhesion strength (3). It is attached. For this reason, with a part of the sealing sheet 5 being peeled off, the region near the sewing machine line is easily separated from the flange A corresponding to the sewing machine. Therefore, a part of the sealing sheet 5 can be easily cut along the sewing line 6 without relatively deviating from the sewing line 6.

Moreover, the said blister package 1 is between the area | regions other than the sewing machine line vicinity area | region of the sealing sheet 5, and the to-be-bonded surface of the sewing machine corresponding flange part A in relation with adhesion strength (1) thru | or adhesion strength (3). Are attached with intermediate strength. For this reason, when a part of peeled sealing sheet 5 is affixed to the flange part 3 again, it can prevent that the sealing sheet 5 peels carelessly.
Specifically, if the adhesion strength of the region near the sewing line of the sealing sheet 5 to the surface to be bonded of the flange A corresponding to the sewing machine is reduced or the adhesion strength is made zero, the sealing line 5 is sealed without relatively deviating from the sewing line 6. The sheet 5 can be easily cut out. However, even if a part of the sealing sheet 5 after being cut off is attached to the flange portion 3 again, a part of the sealing sheet 5 may not be attached to the sewing machine corresponding flange portion A with sufficient adhesion strength.

  In this regard, the adhesion strength (2) between the area other than the area near the sewing machine line of the sealing sheet 5 and the surface to be bonded of the sewing machine corresponding flange part A is determined as follows. By making it larger than the adhesion strength (3) between the surface to which A is applied, a part of the peeled sealing sheet 5 is again sufficiently attached to the flange portion 3 while having the effect of being easily cut along the sewing machine line 6. Can be affixed with good adhesion strength.

  The blister package of the present invention is not limited to the above embodiment, and can be appropriately changed within the scope intended by the present invention. Hereinafter, although the modification of the blister package of this invention is demonstrated, about the structure and effect similar to the said embodiment, the description is abbreviate | omitted and a term and a code | symbol may be used as it is.

In the blister package 1 in the above embodiment, the sewing machine wire 6 of the sealing sheet 5 extends in a direction substantially orthogonal to the direction in which the turnable flange portion B extends. For example, as shown in FIG. The sewing machine line 6 of the sealing sheet 5 may be formed so as to extend in an obtuse angle (or acute angle) direction with respect to the direction in which the turnable flange portion B extends. In the sewing machine line 6 of FIG. 10, the through hole is not substantially Y-shaped but linear.
In this case, the sewing machine corresponding flange portion A of the cover member 4 may also be formed to extend in an obtuse angle (or acute angle) direction with respect to the direction in which the turn corresponding flange portion B extends, as in the above embodiment. The sewing machine corresponding flange portion A may be formed to extend in a direction substantially orthogonal to the direction in which the turn corresponding flange portion B extends.

  Moreover, although the blister package 1 in the said embodiment has the cover member 4 provided with two or more storage recessed parts 2, even if it uses the cover member 4 provided with one storage recessed part 2 as shown in FIG. Good. In this case, the sewing machine line 6 of the sealing sheet 5 is formed at a position spaced from the edge of the storage recess 2 as in the above embodiment.

  The sealing sheet 5 in the above embodiment is formed by laminating the adhesive layer 52 on substantially the entire one surface of the base material 51, and among these, in order to make the region corresponding to the opening of each storage recess 2 a non-adhesive surface, Although the concealing layer 54 is laminated, it is not limited to this. For example, you may laminate | stack the adhesion layer 52 except the area | region corresponding to the opening part of each accommodation recessed part 2 among the one surfaces of the base material 51 (not shown). In this case, since one surface of the base material 51 is exposed in a region corresponding to the opening of each storage recess 2, it is not necessary to provide the concealing layer 54.

  Furthermore, although the sealing sheet 5 in the said embodiment has laminated | stacked the weakening layer 53 on the adhesion layer 52 in order to make a sewing machine line vicinity area | region into a weakening surface, it is not limited to this. For example, the adhesive layer 52 may not be laminated in the vicinity of the machine line, and instead, a weak adhesive having a lower adhesiveness than the adhesive constituting the adhesive layer 52 may be laminated in the vicinity of the sewing line ( Not shown). In this case, however, the normal pressure-sensitive adhesive and the weak pressure-sensitive adhesive having lower adhesiveness must be applied separately, and the application work is complicated. Therefore, the pressure-sensitive adhesive layer 52 as in the above embodiment. A structure in which the weakening layer 53 is laminated on the substrate is preferable.

  Moreover, the blister package 1 in the above embodiment has the above-described relationship between the adhesion strengths (1), (2), and (3) of the sealing sheet 5 to the surface to be bonded of the sewing machine corresponding flange portion A and the turn corresponding flange portion B. In order to obtain Formula Y, the sealing sheet 5 is provided with an adhesive surface and a weakened surface, and the flange portion 3 is formed with an uneven surface. In the present invention, each adhesion strength (1), (2) and ( The present invention is not limited to the above embodiment on condition that 3) satisfies the relational expression X or the relational expression Y.

For example, by making all the adherend surfaces of the flange portion 3 of the cover member 4 flat and using a sealing sheet 5 having the following layer structure, each adhesion strength (1), (2) and (3) It is also possible to constitute a blister package 1 that satisfies the above relational expression Y.
As shown in FIG. 11, the adhesive sheet of this modification includes a base material 51, an adhesive layer 52 laminated on one surface of the base material 51, and a weakened material laminated on a part of one surface of the adhesive layer 52. The layer structure includes a layer 53 and a second weakened layer 56 laminated on one surface of the weakened layer 53.

The weakening layer 53 according to this modification is a layer that weakens the adhesiveness of the adhesive surface of the adhesive layer 52, and can be formed from a masking agent applied to a predetermined thickness as shown in the above embodiment. The weakened layer 53 according to the modified example is provided corresponding to the entire pasting surface of the sewing machine corresponding flange portion A.
The second weakened layer 56 according to this modification can be formed, for example, by further applying a masking agent on the weakened layer 53. The second weakening layer 56 is stacked in the vicinity of the sewing machine line. The area where the second weakened layer 56 is provided is less sticky or substantially less sticky than the stickiness (stickiness of the weakened surface) of the area covered by the weakened layer 53.
In the case of using the sealing sheet 5 in which three types of adhesive regions are formed as in this modification, the flange portion 3 of the cover member 4 (the flange portion 3 including the sewing machine corresponding flange portion A). Even when all of the surfaces to be bonded are made flat, the blister package 1 in which the adhesion strengths (1), (2), and (3) satisfy the relational expression Y is obtained.

  Further, for example, only the adhesive layer 52 is provided on the sealing sheet 5 (the weakening layer 53 and the second weakening layer 56 are not laminated. However, in the region corresponding to the opening of the housing recess 2, the concealing layer is used as described above. 54, or the adhesive layer 52 is not provided), and by forming two types of uneven surfaces on the sewing machine corresponding flange portion A of the cover member 4, each adhesion strength (1), (2) and (3) It is also possible to constitute a blister package 1 that satisfies the relational expression Y (not shown).

The cover member 4 has a surface to be bonded of the sewing machine corresponding flange portion A as an uneven surface. However, the surface to be attached of the flange A corresponding to the sewing machine is divided into a portion where the region near the sewing line of the sealing sheet 5 is attached and a portion where a region other than the region near the sewing line of the sealing sheet 5 is attached. The uneven surface of the part to which the region near the sewing line is affixed is further roughened (the surface roughness is roughened) than the uneven surface of the part to which the region other than the region near the sewing line is affixed.
In the case of using the cover member 4 having the sewing machine corresponding flange portion A in which two types of uneven surfaces are formed as in this modification, even when the sticking surface of the sealing sheet 5 is only the adhesive layer 52, A blister package 1 in which each adhesion strength satisfies the relational expression Y is obtained.

Further, in the blister package 1 of the present invention, the adhesion strengths (1), (2) and (3) preferably satisfy the relationship of the relational expression Y, but the adhesion strengths (1) and (3) are as described above. Any material satisfying the relationship of the relational expression X may be used.
Moreover, the blister package 1 in which the adhesion strengths (1) and (3) satisfy the relationship of the relational expression X is not limited to the above embodiment, and various aspects can be applied.

  For example, only the adhesive layer 52 is provided on the sealing sheet 5 (the weakening layer 53 and the second weakening layer 56 are not laminated. However, in the region corresponding to the opening of the housing recess 2, the concealing layer 54 as described above. Or the adhesive layer 52 is not provided), and only the sewing machine corresponding flange portion A of the cover member 4 is formed on the concavo-convex surface, whereby the blister package 1 satisfying the relationship of the relational expression X is obtained. Further, by laminating the weakening layer 53 on the adhesive layer 52 in the vicinity of the sewing machine line of the sealing sheet 5 and forming the sewing machine corresponding flange portion A of the cover member 4 on a flat surface, the relationship of the above relational expression X is obtained. A filled blister pack 1 is obtained. In addition, the blister package 1 satisfying the relation of the relational expression X can be obtained by various configurations within the range intended by the present invention.

Furthermore, in the said embodiment, although the to-be-attached surface of the sewing machine corresponding flange part A is made into the surface which has difficulty adhesion, the sewing machine corresponding flange part A does not need to be made into the difficulty adhesion surface. That is, the sewing machine corresponding flange portion A may be a surface made of a material for forming the cover member and may be a flat surface.
In the cover member 4 of FIG. 12, the surface to be bonded of the lower corresponding flange portion C is made to be a hard-to-adhere surface (except for the corners intersecting the first flange portion 31 and the third flange portion 33). The to-be-bonded surface of the flange part other than is not a difficult adhesion surface. In FIG. 12, a range that is considered to be a hardly adherent surface is indicated by light ink painting.
By sticking the sealing sheet 5 exemplified in the above embodiment (for example, the sealing sheets shown in FIGS. 7 and 8) to the cover member 4 in the same manner, the adhesion strengths (1) and (3) are related to each other. A blister pack 1 that satisfies the relationship of formula X is obtained.

Moreover, in the said embodiment, although the weakening layer 53 is laminated | stacked on the sewing machine wire vicinity area | region of the sealing sheet 5, it is not limited to this, For example, as shown in FIG. It may be provided with the same width as A. In FIG. 13, the area where one surface of the adhesive layer 52 is exposed is shaded, the area where one surface of the weakening layer 53 is exposed is vertical stripes, and the area where one surface of the concealing layer 54 is exposed is lightly painted. The areas where one side of 51 is exposed are shown as plain.
The weakening layer 53 in this case is not a layer that conceals the adhesiveness of the adhesive surface, but a layer that weakens the adhesiveness of the adhesive surface of the adhesive layer 52.
By sticking the sealing sheet 5 on the cover member 4 exemplified in the above embodiment (for example, the cover member shown in FIG. 6) in the same manner, the adhesion strengths (1) and (3) have the relationship of the above relational expression X. The blister package 1 satisfying the above is obtained.
Moreover, it is also possible to affix this sealing sheet 5 to the cover member 4 as shown in FIG. 12, and to comprise the blister package 1 of this invention.

  As means for setting the adhesion strengths (1) to (3) so as to satisfy the relationship of the relational expression X or the relational expression Y, the weakening layer is formed on the adhesive layer 52 in the vicinity of the sewing machine line of the sealing sheet 5. 53 are preferably laminated. The adhesive layer 52 is relatively soft and the weakened layer 53 is harder than this. For this reason, by laminating the weakening layer 53 on the adhesive layer 52 in the vicinity of the sewing machine line, the threading phenomenon of the adhesive can be suppressed when the sealing sheet 5 is cut along the sewing machine line. It becomes easy to cut off the sealing sheet 5 along.
