  The objective of this invention is providing the blister container which can open an sealing sheet, can take out articles | goods from a storage recessed part, and can reseal the sealing sheet.

The blister container of the present invention includes a cover member having a storage recess, and a sealing sheet that closes the opening of the storage recess, and the sealing sheet is a laminate in which a first sheet and a second sheet are stacked. In order to form an opening / closing part in the sealing sheet, a first cut line that is non-linear in plan view is formed in the plane of the first sheet, and the second sheet A second non-linear cut line in plan view that is displaced from the first cut line is formed in a plane, a section sandwiched between the first cut line and the second cut line , and The first sheet and the second sheet are bonded via an adhesive layer except for an outer vicinity area of the first cutting line and an inner vicinity area of the second cutting line, and the first cutting line of the section is the first cutting line. a first sheet in the vicinity of the inside area and the area excluding the outer region near the second score line of write line A second sheet of interlayer, an adhesive layer is provided.

In the blister container of the present invention, an adhesive layer is not provided between the first sheet and the second sheet in the section sandwiched between the first cut line and the second cut line. Since the pressure-sensitive adhesive layer is provided, the interlayer between the first sheet and the second sheet in the section is adhered to each other.
When a part of the first sheet is separated using this first score line, the pressure-sensitive adhesive surface of the pressure-sensitive adhesive layer is peeled off from the first sheet or the second sheet in the section, and is further pulled by the first sheet. Then, a part of the second sheet separates according to the second cut line. Therefore, a part of the first sheet and a part of the second sheet (corresponding to the opening / closing part) are swollen from the sealing sheet, and within the range surrounded by the first cut line and the second cut line, the storage recess of the cover member An outlet leading to is generated. Accordingly, the article can be taken out from the outlet or returned.
On the other hand, when the separated part of the first sheet and part of the second sheet (opening / closing part) are returned to the original state, the interlayer between the first sheet and the second sheet in the section is pasted again through the adhesive layer. The outlet can be resealed to wear.
Moreover, in the blister container of this invention, the adhesive layer is not provided in the inner side vicinity area | region of the 1st cut line, and the outer side vicinity area | region of the 2nd cut line, respectively, Furthermore, the outer side of the 1st cut line Since the space between the first sheet and the second sheet in the vicinity area and the inner vicinity area of the second cut line is an adhesive avoidance space, the pressure-sensitive adhesive in the pressure-sensitive adhesive layer is the first cut line and the second cut line. It is possible to effectively prevent oozing through.

  In a preferred blister container of the present invention, the cover member has a flange portion extending from an end edge of the storage recess, and the second sheet of the sealing sheet is bonded to the surface to be bonded of the flange portion. Thus, the sealing sheet closes the opening of the housing recess of the cover member, and all or part of the section sandwiched between the first cut line and the second cut line is bonded to the flange portion. It overlaps the surface.

  In such a blister container, since all or a part of the section overlaps the adherend surface of the flange portion, the second sheet corresponding to the section is reinforced by the flange portion. Therefore, when the first sheet corresponding to the section is pressed against the second sheet in order to return the raised opening / closing part to the original state, the second sheet is hardly distorted, and the first sheet and the second sheet are adhered to each other. It can be reattached easily and reliably through the agent layer.

Further preferred blister containers of the present invention are the width of the inner vicinity region of the first cut line, the width of the outer vicinity region of the first cut line, the width of the inner vicinity region of the second cut line, and the second cut. The width of the area near the outside of the line is 1 mm to 5 mm, respectively .

1 to 5, the blister container 10 of the present invention capable of forming an opening / closing portion includes a cover member 4 in which a housing recess 41 is formed, and a sealing sheet 3 that closes the opening of the housing recess 41. Have.
The cover member 4 includes the storage recess 41 and a flange portion 42 that extends integrally from the storage recess 41.
The sealing sheet 3 is formed from a laminated sheet having the first sheet 1 and the second sheet 2. In order to form a resealable opening / closing part in the surface of the sealing sheet 3, a first cut line 11 having a non-linear shape in plan view is formed in the surface of the first sheet 1, and In the plane of the second sheet 2, a second cut line 22 is formed that is non-linear in plan view and is displaced from the first cut line 11. An adhesive layer 5 is provided between the first sheet 1 and the second sheet 2 in the section A sandwiched between the first cut line 11 and the second cut line 22.
This will be specifically described below.

The cover member 4 is formed of a synthetic resin molded product, and is a relatively rigid member.
The material of the cover member 4 is not particularly limited, and examples thereof include thermoplastic 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 for the sheet molding method include a thermoplastic resin sheet and a laminated sheet in which a plurality of thermoplastic resin sheets are integrally laminated.
The cover member 4 has a thickness of 0.1 to 2 mm, preferably 0.2 to 1 mm.

A housing recess 41 protruding in a convex shape is formed in a part of the cover member 4. The storage recess 41 of the cover member 4 is a concave space portion that stores articles. The storage recess 41 includes a front wall 411 and a peripheral wall 412 extending substantially orthogonally to the front wall 411 from the peripheral edge of the front wall 411, and the end edge of the peripheral wall 412 There is an opening for putting in and out the article in a portion surrounded by 412a.
The shape of the storage recess 41 is appropriately designed according to the shape of the article. In the present embodiment, the front wall 411 of the storage recess 41 is formed in a substantially rectangular shape in plan view. Corresponding to the front wall 411 having a substantially rectangular shape in plan view, the peripheral wall 412 is formed in a rectangular tube shape including four upstanding surfaces.

Further, a flange portion 42 is extended from the end edge 412 a of the storage recess 41 (end edge 412 a of the peripheral wall 412) in a direction orthogonal to the peripheral wall 412. The flange portion 42 has a flat surface whose normal is the protruding direction of the storage recess 41. Since the flange portion 42 is formed around the storage recess 41, the flat surface of the flange portion 42 is annular so as to surround the storage recess 41.
The flat surface of the flange portion 42 becomes a bonded surface 421 to which the sealing sheet 3 is bonded.

After putting an article into the housing recess 41 of the cover member 4, the article-containing blister container 10 is obtained by bonding the second sheet 2 of the sealing sheet to the adherend surface 421 of the flange portion 42.
The adhesion method of the sealing sheet 3 with respect to the flange part 42 is not specifically limited, For example, the adhesion | attachment using an adhesive agent, the adhesion | attachment by heat fusion, the welding using a solvent, etc. are mentioned.

The outer shape of the sealing sheet 3 substantially matches the outer shape of the flange portion 42 of the cover member 4. However, the shape of the sealing sheet 3 and the outer shape of the flange portion 42 are not limited to the same, and the sealing sheet 3 is larger than the outer shape of the flange portion 42 (in this case, sealing from the outer edge of the flange portion 42). A part of the stop sheet 3 extends), or the sealing sheet 3 may be smaller than the outer shape of the flange portion 42. The shape of the sealing sheet 3 is not particularly limited as long as it is formed in a size that can at least close the opening of the housing recess 41.
In order to form an opening / closing part (article outlet) leading to the housing recess 41 of the cover member 4 in the surface of the sealing sheet 3, the first sheet 1 and the second sheet 2 have first and second surfaces respectively. A first cut line 11 and a second cut line 22 are formed.

  The shape of the first score line 11 is a non-linear shape in plan view, and the shape of the second score line 22 is a non-linear shape in plan view displaced from the first score line 11. The first sheet 1 and the second sheet 2 are bonded to each other between the first sheet 1 and the second sheet 2 in the section A sandwiched by the displaced first cut line 11 and second cut line 22. Therefore, the adhesive layer 6 is not provided. Instead of the adhesive layer 6, an adhesive layer 5 is provided between the first sheet 1 and the second sheet 2 in the section A between the first cut line 11 and the second cut line 22. ing. By providing the adhesive layer 5 in the section A, it is possible to repeatedly perform adhesion and peeling between the layers of the first sheet 1 and the second sheet 2 in the section A.

The material of the 1st sheet | seat 1 is not specifically limited, A conventionally well-known thing can be used. As the first sheet 1, for example, a synthetic resin sheet such as polyethylene terephthalate (herein, the sheet is generally synonymous with what is called a film), a nonwoven fabric, a foamed resin sheet, paper, and the like. Can be mentioned. The first sheet 1 is a laminate of two or more sheets selected arbitrarily (for example, a laminate in which two or more synthetic resin sheets are integrally laminated, or a synthetic resin sheet and paper are integrated. In other words, it may be a laminated body or the like laminated in a stacked manner. Moreover, the 1st sheet | seat 1 may be the laminated body by which the gas barrier layer and / or the light barrier layer were laminated | stacked integrally on the above various sheets or laminated bodies.
The first sheet 1 is made of a synthetic resin sheet, a laminate including a synthetic resin sheet, or a gas barrier layer and / or an optical barrier layer on the first sheet 1 because it is excellent in processability and hardly damaged even when repeatedly opened and closed. It is preferable to use a laminated body.

The first sheet 1 may be transparent or non-transparent. Furthermore, the first sheet 1 may be subjected to design printing as necessary.
The thickness of the first sheet 1 is not particularly limited. When a synthetic resin sheet or a laminate including the same is used as the first sheet 1, the thickness is generally 15 μm to 120 μm.

The material of the 2nd sheet | seat 2 is also not specifically limited, The sheet | seat or laminated body which was illustrated with the said 1st sheet | seat 1 can be used. The second sheet 2 may be the same sheet as the first sheet 1 or a different sheet.
When the sealing sheet 3 is bonded to the flange portion 42 of the cover member 4 by heat fusion, the second sheet 2 preferably has a sealant layer. For example, the second sheet 2 has a single layer of a sealant layer, or a sealant layer and another layer (for example, a synthetic resin sheet different from the sealant layer), and the sealant layer is integrally laminated on the outermost surface. It is preferable to use the laminated body made.

The sealant layer is a layer that can be melted by heating and bonded to the adherend surface 421 of the flange portion 42. Examples of the sealant layer include a general-purpose polyethylene layer.
The second sheet 2 may be transparent or non-transparent.
The thickness of the second sheet 2 is not particularly limited. When a single layer of a sealant layer is used as the second sheet 2, the thickness is generally 15 μm to 70 μm.

  The adhesive layer 6 has a section A sandwiched between the first cut line 11 and the second cut line 22 (in this section A, the inner vicinity region 11i of the first cut line 11 and the second cut line 22 Each of the first sheet 1 and the second sheet 2 and the outer vicinity area 11o of the first score line 11 and the inner vicinity area 22i of the second score line 22). The first sheet 1 and the second sheet 2 are interposed between the second surface of the first sheet 1 and the first surface of the second sheet 2 except for the interlayer between the first sheet 1 and the second sheet 2. The first sheet 1 and the second sheet 2 are laminated and bonded through the adhesive layer 6.

The inside vicinity region 11i of the first cut line 11 is a width that is adjacent to the inside of the first cut line 11 and extends along the first cut line 11 with respect to the first cut line 11. It is a narrow belt-like region. The outside vicinity region 11 o of the first cut line 11 is a narrow band-like region that is adjacent to the outside of the first cut line 11 and extends along the first cut line 11.
The outside vicinity region 22o of the second cut line 22 is a width adjacent to the outside of the second cut line 22 and extending along the second cut line 22 with respect to the second cut line 22. It is a narrow belt-like region. The inside vicinity region 22 i of the second cut line 22 is a narrow band-like region that is adjacent to the inside of the second cut line 22 and extends along the second cut line 22.

The adhesive layer 6 is a layer for firmly bonding the first sheet 1 and the second sheet 2. In the portion where the adhesive layer 6 is provided, the first sheet 1 and the second sheet 2 cannot be substantially delaminated by human power. That is, the first sheet 1 and the second sheet 2 are firmly bonded by the adhesive layer 6.
The adhesive layer 6 can be provided between the sheets 1 and 2 by applying a known adhesive to a predetermined range of the second surface of the first sheet 1 or the first surface of the second sheet 2. .
The first surface of the first sheet 1 refers to the surface of the two surfaces of the first sheet 1 that is opposite to the surface that is bonded to the second sheet 2, and the second surface of the first sheet 1. The surface refers to a surface on the side bonded to the second sheet 2. The first surface of the second sheet 2 refers to the surface of the two surfaces of the second sheet 2 that is bonded to the first sheet 1, and the second surface of the second sheet 2 is the surface on the opposite side. Point to.

  The adhesive is not particularly limited and includes, for example, a dry laminate adhesive, a wet laminate adhesive, a heat-sensitive adhesive, an ultraviolet curable adhesive, and the like. An ultraviolet curable adhesive is used.

And the said sealing sheet 3 is formed with the opening-and-closing part which opens and closes the taking-out port for taking out articles | goods. The size (opening area) of the outlet is appropriately designed according to the article so that the article can be taken out therefrom.
The outlet is an opening formed in the sealing sheet 3 by separating a part of the first sheet 1 and a part of the second sheet 2 according to the first cut line 11 and the second cut line 22. .
The opening / closing part includes a part of the first sheet 1 and a part of the second sheet 2 that are separated from the sealing sheet 3 according to the first cut line 11 and the second cut line 22.

The formation place of the 1st cut line 11 and the formation place of the 2nd cut line 22 do not correspond, and the 2nd cut line 22 has shifted from the 1st cut line 11. The misalignment includes a case where the first cut line 11 and the second cut line 22 partially intersect when partially intersecting, that is, when viewed from a plane.
In the present embodiment, the second score line 22 is formed away from the first score line 11 with reference to the first score line 11. In particular, it is preferable that the first cut line 11 and the second cut line 22 do not partially intersect (both lines do not partially intersect when viewed from a plane).

Specifically, the first cut line 11 is positioned outside the edge 412a of the storage recess 41 of the cover member 4 in a state where the sealing sheet 3 is bonded to the flange portion 42 of the cover member 4. The first sheet 1 is formed.
The shape of the first score line 11 is a non-linear shape with ends having both ends. For example, the non-linear first cut line 11 with ends has both ends, and one side of the sealing sheet 3 from the virtual straight line connecting the both ends (in this embodiment, one side in the vertical direction). It is formed in a non-linear shape in plan view.

On the other hand, the second cut line 22 is slightly along the edge 412a of the storage recess 41 of the cover member 4 or slightly less than the edge 412a in a state where the sealing sheet 3 is bonded to the flange portion 42 of the cover member 4. It forms in the 2nd sheet | seat 2 so that it may be located inside.
The shape of the second cut line 22 is either a non-linear end shape having both ends or an endless non-linear shape. The endless non-linear cut line is a cut line having a shape that forms a closed region inside thereof (that is, an annular cut line).
When the second cut line 22 is a non-linear end with a both ends, like the first cut line 11, the second cut line 22 has both ends. It is formed in a non-linear shape in a plan view that swells from the connected virtual straight line to one side of the sealing sheet 3.

In a state where the sealing sheet 3 is bonded to the flange portion 42 of the cover member 4, the first cut line 11 is located outside the end edge 412 a of the storage recess 41 of the cover member 4 and the second cut line 22. Is located along the edge 412a of the storage recess 41 of the cover member 4 or slightly inside the edge 412a, so that the section A sandwiched between the first cut line 11 and the second cut line 22 Is partially or entirely overlapped with the adherend surface 421 of the flange portion 42. That is, the second sheet 2 of the sealing sheet 3 is bonded to the adherend surface 421 of the flange portion 42 including a portion corresponding to all or part of the section A.
In addition, when the 2nd cut line 22 is formed along the edge 412a of the storage recessed part 41 of the cover member 4, all the said division A will overlap with the to-be-adhered surface 421 of the flange part 42. FIG. .

More specifically, the first cut line 11 includes one end and the other end, a pair of first vertical cut lines 111 extending from the both ends to one side in the vertical direction, and a pair of first cut lines. And a first horizontal cut line 112 that is connected to the vertical cut line 111 and extends in the horizontal direction. The pair of first vertical cut lines 111 and first horizontal cut lines 112 are formed at positions that overlap the adherend surface 421 of the flange portion 42.
Further, the central portion in the horizontal direction of the first horizontal cut line 112 swells in a substantially arc shape on one side in the vertical direction. A region surrounded by a substantially arc shape of the first horizontal cut line 112 functions as a knob when the opening / closing portion is rolled out. In addition, in order to make it easy to pick, between the layers of the first sheet 1 and the second sheet 2 in the region surrounded by the substantially arc shape of the first horizontal cut line 112, as shown in FIG. (Or in the case where the pressure-sensitive adhesive layer 5 is provided also in this region, it is preferable to laminate a concealing layer for suppressing the adhesion).

  The second cut line 22 has one end and the other end, a pair of second vertical cut lines 221 extending from the both ends to one side in the vertical direction, and a pair of second vertical cut lines 221. And a second lateral cut line 222 extending in the lateral direction.

The second vertical cut line 221 and the second horizontal cut line 222 are formed so as to be displaced inward from the first vertical cut line 111 and the first horizontal cut line 112, respectively. Specifically, the pair of second vertical cut lines 221 and second horizontal cut lines 222 are formed along the edge 412a of the storage recess 41 of the cover member 4, and accordingly, the second vertical cut lines The line 221 and the second horizontal cut line 222 do not overlap the adherend surface 421 of the flange portion 42.
Since the first cut line 11 and the second cut line 22 are formed so as to be displaced, a part of the first sheet 1 is interposed between the first cut line 11 and the second cut line 22. A section A where a part of the second sheet 2 comes into contact with each other is generated.

  The interval between the second vertical cut line 221 and the first vertical cut line 111 and the interval between the second horizontal cut line 222 and the first horizontal cut line 112 (that is, the first cut line 11 and the second cut line). The interval between the sections A sandwiched between the lead wires 22 is not particularly limited, and can be set as appropriate. However, if the interval is too narrow, the width of the pressure-sensitive adhesive layer 5 becomes narrow accordingly, and therefore there is a possibility that the interlayer between the first sheet 1 and the second sheet 2 in the section A cannot be adhered. Considering this point, the interval is preferably 5 mm or more, and more preferably 7 mm or more. Moreover, even if the said space | interval is wide, the effect of this invention does not change, but if the said space | interval is too wide, the part (entrance) relatively surrounded by the 2nd cut line 22 will become narrow. Considering this point, the interval is preferably 20 mm or less.

In the present embodiment, the interval between the first vertical cut line 111 and the second vertical cut line 221 is substantially constant in the vertical direction, and the first horizontal cut line 112 and the second horizontal cut line 222 are Is substantially constant in the horizontal direction (however, the interval between the central portion in the horizontal direction of the first horizontal cut line 112 and the second horizontal cut line 222 is excluded). That is, the plan view shape of the second score line 22 is smaller than the plan view shape of the first score line 11 and is similar to the shape.
But the space | interval of the 1st vertical cutting line 111 and the 2nd vertical cutting line 221 and the space | interval of the 1st horizontal cutting line 112 and the 2nd horizontal cutting line 222 are not substantially constant, At least any one of them The spacing may be gradually increased or may be partially different.

Here, the cut lines (the first cut line 11 and the second cut line 22) are continuous lines of cuts penetrating in the thickness direction of the sheet or cuts formed in a substantially V shape in the thickness direction of the sheet. Means a continuous line of eyes. The continuous line of cuts engraved in the substantially V shape is a cut line that does not penetrate the sheet, and is generally called a half-cut line.
As shown in FIG. 1 and FIG. 3, the cut line or the cut line may be continuous as a whole, or the cut line or the continuous line of the cut line is intermittently connected. It may be a thing (a long continuous line X is connected with a short interval Y as shown in FIG. 6). Thus, even if it is a cut line constituted by connecting continuous lines of cuts intermittently, the sheet can be cut according to this cut line.

In addition, what the continuous line of the said cut | interruption connects intermittently can also be said to be a perforation which has a comparatively long through-hole part.
Since the opening / closing part can be easily separated from the first sheet 1 and the second sheet according to the first cut line 11 and the second cut line 22, the first cut line 11 and the second cut line 22 It is preferable that a continuous line of slits penetrating in the thickness direction or a continuous line of slits penetrating in the thickness direction of the sheet is intermittently connected.

In the present embodiment, an intermediate region between the first cut line 11 and the second cut line 22 (the first cut in the section A between the first cut line 11 and the second cut line 22). The adhesive layer 5 is provided between the first sheet 1 and the second sheet 2 in a region excluding the inner vicinity region 11 i of the lead wire 11 and the outer vicinity region 22 o of the second cut line 22.
That is, the pressure-sensitive adhesive layer 5 is a range of the section A sandwiched between the first cut line 11 and the second cut line 22 so as not to overlap the first cut line 11 and the second cut line 22, respectively. Is provided inside.

The pressure-sensitive adhesive layer 5 is provided along the first score line 11 and the second score line 22.
As shown in the drawing, the pressure-sensitive adhesive layer 5 is preferably provided in a continuous band-shaped range along the second cut line 22. Since the pressure-sensitive adhesive layer 5 is provided in a continuous band shape, the first sheet 1 and the second sheet 2 in the section A are in close contact with each other through the pressure-sensitive adhesive layer 5. The blister container 10 in which the storage recess 41 is sealed with the sealing sheet 3 can be provided.
However, the adhesive layer 5 may be provided intermittently along the first cut line 11 and the second cut line 22. That the adhesive layer 5 is provided intermittently means that a plurality of adhesive layers 5 having a certain area are arranged in parallel along the first cut line 11 and the second cut line 22 with a slight gap therebetween. It has been done.

  The pressure-sensitive adhesive layer 5 can be provided by applying a known pressure-sensitive adhesive to either the second surface of the first sheet 1 or the first surface of the second sheet 2 in the intermediate region, preferably The adhesive layer 5 is provided on the first sheet 1 by applying an adhesive to the second surface of the first sheet 1. By providing the pressure-sensitive adhesive layer 5 on the first sheet 1, there is an advantage that the article hardly adheres to the pressure-sensitive adhesive layer 5 while opening and closing the opening / closing part.

  When a pressure-sensitive adhesive is applied to the second surface of the first sheet 1 in the section A, the pressure-sensitive adhesive surface of the pressure-sensitive adhesive layer 5 adheres to the first surface of the second sheet 2 in the section A. Can delaminate between. In order to adjust the adhesive strength of the pressure-sensitive adhesive layer 5, the pressure-sensitive adhesive is applied to the other side to which the pressure-sensitive adhesive is not applied (for example, when the pressure-sensitive adhesive is applied to the second surface of the first sheet 1). The release agent may be applied thinly on the first surface of the second sheet 2 where the adhesive surface of the layer 5 faces.

Although the width | variety of the adhesive layer 5 is not specifically limited, Since there exists a possibility that an opening-and-closing part cannot be resealed reliably when too narrow, 3 m or more is preferable and 5 mm or more is more preferable.
The thickness of the pressure-sensitive adhesive layer 5 is usually about 5 μm to 25 μm.

The pressure-sensitive adhesive is not particularly limited, and examples thereof include a pressure-sensitive pressure-sensitive adhesive, a heat-sensitive pressure-sensitive adhesive, and an ultraviolet curable pressure-sensitive adhesive. Generally, a pressure-sensitive pressure-sensitive adhesive is used.
Adhesive is an adhesive that can be attached between two adherends and has an adhesive strength that allows the adherend to be peeled off by hand and can be reapplied after peeling. Things (those that remain sticky after peeling).
Specifically, the adhesive strength of the pressure-sensitive adhesive layer 5 is not particularly limited, but the adhesive strength of the pressure-sensitive adhesive layer 5 is preferably 1 to 5 N / 15 mm.

  The adhesive strength of the pressure-sensitive adhesive layer 5 is a value measured by a method according to JIS Z 0237 180 degree peeling. Specifically, the adhesive strength is obtained by cutting a sheet in which the first sheet 1 and the second sheet 2 are bonded via an adhesive into a size of 100 mm × 15 mm, a temperature of 23 ± 2 ° C., a humidity of 50 ± 5% RH, and 300 mm. The maximum strength when peeled at a rate of / min.

In the present embodiment, as described above, the inner vicinity area 11i of the first score line 11, the outer vicinity area 11o of the first score line 11, the outer vicinity area 22o of the second score line 22, and the first The adhesive layer 5 and the adhesive layer 6 are not provided between the first sheet 1 and the second sheet 2 in each of the inner vicinity regions 22i of the two cut lines 22, and these adjacent regions are The non-sticking area.
The interlayer between the first sheet 1 and the second sheet 2 in the non-adhering region is not adhered, and there is a slight gap between the layers.

The width of the inner vicinity area 11i of the first score line 11, the width of the outer vicinity area 11o of the first score line 11, the width of the inner vicinity area 22i of the second score line 22, and the width of the second score line 22 The width of the outer vicinity region 22o is not particularly limited. However, if these widths are too narrow, the effects of the present invention may not be sufficiently exerted. On the other hand, if these widths are too wide, the width of the pressure-sensitive adhesive layer 5 becomes relatively narrow, and the opening / closing operation is performed. While opening and closing the part, there is a possibility that foreign matter may be caught between the first sheet 1 and the second sheet 2 in the vicinity region. From such a viewpoint, these widths are each preferably about 1 mm to 5 mm, and more preferably about 1 mm to 3 mm.
Reference numeral 9 denotes a suspension hole for the blister container 10.

The blister container 10 is produced, for example, as follows.
Adhesive and pressure-sensitive adhesive within a predetermined range of the second surface of the long first sheet 1 (or the first surface of the long second sheet 2) (the planned formation range of the adhesive layer 6 and the pressure-sensitive adhesive layer 5) After the coating, the first surface of the long second sheet 2 (or the second surface of the long first sheet 1) is bonded to form a laminated sheet. Next, the 1st score line 11 is engraved using the cutter blade from the 1st surface side of the 1st sheet 1 so that it may correspond between adhesive layer 6 and adhesive layer 5, and the 2nd sheet 2 The 2nd score line 22 is carved using the cutter blade from the 2nd surface side. The obtained long laminated sheet (continuous body in which the sealing sheets 3 are continuously connected) is wound around a roll as necessary.

  As described above, the inner vicinity area 11i of the first score line 11, the outer vicinity area 11o of the first score line 11, the outer vicinity area 22o of the second score line 22, and the second score line. Since the pressure-sensitive adhesive layer 5 is not provided in the inner vicinity region 22 i of the pressure-sensitive adhesive 22, it is difficult for the pressure-sensitive adhesive to ooze out. For this reason, the lamination sheet wound up by the roll does not raise | generate blocking.

  Next, one sheet of sealing sheet 3 is cut out from the long laminated sheet. The second sheet 2 side of the sealing sheet 3 is directed toward the adherend surface 421 side of the flange portion 42 of the cover member 4 in which the article is placed in the housing recess 41, and the second cut line of the second sheet 2 is provided. 22 is made to substantially coincide with the edge 412 a of the storage recess 41, and the sealing sheet 3 is overlaid on the flange portion 42. Finally, the blister container 10 of the present invention is obtained by heat-sealing (heat-sealing) the second surface of the second sheet 2 of the sealing sheet 3 and the adherend surface 421 of the flange portion 42. In place of the heat fusion, the second surface of the second sheet 2 and the adherend surface 421 of the flange portion 42 may be bonded using a known adhesive.

In the obtained blister container 10 with the article, the opening of the storage recess 41 of the cover member 4 is sealed with the sealing sheet 3. Further, the second surface of the second sheet 2 of the sealing sheet 3 bonded to the bonded surface 421 of the flange portion 42 corresponds to the section A sandwiched between the first cut line 11 and the second cut line 22. Part to be included.
The articles placed in the blister container 10 are not particularly limited, and examples thereof include cosmetics, solid pharmaceuticals, quasi-drugs such as interdental brushes, foods such as sweets, toys, stationery, and dry batteries. .

In the blister container 10, the first cut line 11 and the second cut line 22 are formed in the first sheet 1 and the second sheet 2, and are sandwiched between the first cut line 11 and the second cut line 22. The adhesive layer 6 is not provided between the first sheet 1 and the second sheet 2 in the section A, but the pressure-sensitive adhesive layer 5 is provided in place of the adhesive layer 6, so that the first sheet in the section A is provided. The layers between the first sheet 2 and the second sheet 2 are adhered to each other.
In particular, when the pressure-sensitive adhesive layer 5 is provided in a continuous strip shape as illustrated, the sealing performance of the blister container 10 is maintained. The blister container 10 is also suitable for packaging cosmetics, solid pharmaceuticals, quasi drugs, foods, and the like.

  Further, in the blister container 10, the inner vicinity area 11 i of the first cutting line 11, the outer vicinity area 11 o of the first cutting line 11, the outer vicinity area 22 o of the second cutting line 22, and the second cutting line Since the adhesive layer 5 is not provided in each region of the inner vicinity region 22 i of the feeder line 22, the adhesive of the adhesive layer 5 passes through the first score line 11 and the second score line 22 to the first sheet. It is possible to effectively prevent the first surface side of 1 and the second surface side of the second sheet 2 from oozing out. Specifically, when the pressure-sensitive adhesive layer is covered on the score line, the pressure-sensitive adhesive oozes through the score line. In the present invention, the pressure-sensitive adhesive layer 5 has the first score line 11 and the second score line. Since it does not exist on 22, the bleeding of the adhesive can be effectively prevented.

The effect of preventing the adhesive from bleeding out is also exhibited when a non-penetrating cut line is used as the first cut line 11 and the second cut line 22. However, when a non-penetrating cut line is used, the adhesive can ooze out after the sealing sheet 3 is cut using the non-penetrating first cut line 11 and the second cut line 22. There is sex. In this regard, as described above, by not providing the adhesive layer 5 in each adjacent region such as the inner vicinity region 11i of the first cut line 11, the adhesive can be used even before opening and closing the opening / closing part. Can be effectively prevented.

The blister container 10 is particularly suitable for packaging of solid pharmaceuticals, quasi-drugs, and foods because the adhesive is difficult to penetrate into the storage recess 41 through the second cut line 22.

When taking out the article from the blister container 10, the edge of the knob is picked up, the knob is picked up, and the first sheet 1 is rolled up. Note that the inside of the knob (the area near the inner side of the region surrounded by the substantially arc shape of the first horizontal cut line 112) is a non-sticking area, so by inserting a nail into the edge of the knob This can be easily beaten.
When the first sheet 1 is rolled up, a part of the first sheet 1 moves away from the sealing sheet 3 along the first cut line 11 and the adhesive surface of the adhesive layer 5 is the second in the section A. The sheet 2 is peeled off from the first surface. Furthermore, it is pulled by the first sheet 1 and a part of the second sheet 2 is separated from the bag body 4 according to the second cut line 22 (see FIGS. 7 and 8). In this way, a part of the first sheet 1 and a part of the second sheet 2 (opening / closing part 8) are wound from the sealing sheet 3, and the storage recess 41 of the cover member 4 is within the range surrounded by the second cut line 22. An outlet 7 leading to is produced. Accordingly, the article can be taken out from the outlet 7 or can be returned.

Moreover, when the opened opening / closing part 8 is returned to the original state, the interlayer between the first sheet 1 and the second sheet 2 in the section A sandwiched between the first cut line 11 and the second cut line 22 is an adhesive. The outlet 7 can be resealed because it is attached again via the layer 5. In particular, when the pressure-sensitive adhesive layer 5 is provided in a continuous band-like range, the outlet 7 can be resealed in a sealed state by re-sticking the opening / closing part 8.
As described above, according to the blister container 10 of the present invention, the article can be taken out from the outlet 7 and the outlet 7 can be resealed by the opening / closing part 8, and this can be repeated.

  In addition, since all or a part of the section A sandwiched between the first cut line 11 and the second cut line 22 overlaps the adherend surface 421 of the flange portion 42, the second corresponding to the section A. The second sheet 2 is reinforced by a flange portion 42 bonded to the back of the sheet 2. For this reason, when the first sheet 1 corresponding to the section A is pressed against the first surface of the second sheet 2 in order to return the opened and closed part to the original state, the second sheet 2 is hardly distorted. The interlayer between the first sheet 1 and the second sheet 2 can be easily reattached via the adhesive layer 5.
