Description

  The present invention relates to a blister container that is suspended and displayed.

Conventionally, blister containers are known as containers for packaging various products such as cosmetics.
The blister container is generally a molded product of a synthetic resin transparent sheet and has a cover member formed with a convex portion for storing the product, and a closing sheet that closes the opening side corresponding to the convex portion of the cover member. And a suspension hole penetrating the cover member and the closing sheet.
Such a blister container is displayed in the form of a package containing a product, suspended through the suspension holes.

By the way, the blister container in which the product is stored is easily inclined downward by its own weight when suspended. In order to prevent the inclination as described above, Patent Document 1 discloses a mount having a first hanging hole formed in the upper portion and a second communicating with the first hanging hole with an interval. There is disclosed a blister container (hereinafter referred to as a blister container of Conventional Example 1) having a support member having a support part in which a suspension hole is formed and a cover member that is connected to the support part and wraps a product. ([0012] to [0015] of Patent Document 1 and FIG. 1 and the like).
Further, in Patent Document 1, a mount having a first suspension hole formed in the upper portion and a second suspension hole communicating with the first suspension hole with a space therebetween are formed. A blister container (hereinafter referred to as the blister container of Conventional Example 2) having a rectangular support portion and a cover member having a cover portion provided on the lower side of the support portion via a flat joint portion. ([0020] to [0021] of Patent Document 1 and FIGS. 5 to 6 and the like).

Japanese Patent Laid-Open No. 9-142531

However, in the blister container of Conventional Example 1, dust or dust (hereinafter referred to as foreign matter) enters the support portion through the first suspension hole and / or the second suspension hole, and the foreign matter is supported by the support portion. There is a problem that foreign matter adheres to the stored product due to intrusion into the cover portion connected to the product.
On the other hand, in the blister container of Conventional Example 2, since the joint portion where the flat cover member and the mount are joined is interposed between the support portion and the cover portion, the first suspension hole and / or Even if foreign matter enters the support portion through the second suspension hole, the foreign matter does not enter the cover portion and does not adhere to the product. However, in the blister container of Conventional Example 2, since a flat joint portion is interposed between the support portion and the cover portion, it is easy to bend at the joint portion. For this reason, the blister container of Conventional Example 2 is bent at the joint portion when suspended, and the product tends to tilt downward.

  An object of the present invention is to provide a blister container that is difficult to tilt downward when suspended and that can prevent foreign matter from adhering to a product.

  The blister container of the present invention has a cover member in which a convex portion is projected and a first suspension hole is formed above the convex portion, the opening side corresponding to the convex portion is closed, and the first A closing sheet formed with a second suspension hole facing the suspension hole with a gap, and between the convex portion and the closure sheet, the gap, A product storage space portion connected to the gap portion is formed, and a partition member for partitioning the gap portion and the product storage space portion is mounted inside the convex portion of the cover member.

The blister container of the present invention is normally suspended by passing through the gap from the second suspension hole and passing through the hanger rod to the first suspension hole. Since the first suspension hole formed in the convex part of the cover member and the second suspension hole formed in the closing sheet face each other with a gap, the weight of the product is blocked by the cover member. Hang on each sheet. Furthermore, the said space | gap part and the goods storage space part provided in a row by the said space | gap part are formed between the convex part formed in the cover member, and the obstruction | occlusion sheet | seat. In other words, since the gap and the product storage space are formed by the convex portions protruding from the cover member, there is no possibility that the blister container is curved between the gap and the product storage space. Therefore, the blister container of the present invention is difficult to tilt when suspended.
On the other hand, since the partition member that partitions the product storage space portion and the gap portion is mounted, even if a foreign matter enters the gap portion through the first hanging hole and / or the second hanging hole, Intrusion into the product storage space can be prevented. Therefore, the blister container of the present invention can prevent foreign matters from adhering to the product.

In a preferred blister container of the present invention, the partition member has a partition wall that partitions the product storage space and the gap, and a side wall provided at an end of the partition wall, and the side wall is the convex. The partition member is fitted inside the convex portion of the cover member so as to be in close contact with the inner surface of the portion.
Thus, if the side wall of the partition member is in close contact with the inside of the convex portion of the cover member, it is difficult for foreign matter to enter the product storage space through the gap between the partition wall and the cover member, and the foreign matter adheres to the product. Can be prevented more reliably. Furthermore, since the partition member is fitted so that the side walls are in close contact with each other, the partition member can be attached to a predetermined position of the cover member by close contact without using an adhesive.

In another preferred blister container of the present invention, the partition member is integrally extended from the edge of the cover member.
Thus, when the partition member is integrally extended from the edge part of the cover member, a cover member and a partition member can be shape | molded simultaneously. Further, by folding the partition member with respect to the cover member, the partition member can be easily mounted inside the convex portion of the cover member.

The blister container of the present invention can reliably prevent tilting downward due to the weight of the product when the product is stored and suspended.
Furthermore, the blister container of the present invention can prevent foreign matter from adhering to the product even if foreign matter enters from the hanging hole.

The blister package 1 includes a product 2 and a blister container 3 in which the product 2 is stored.
However, the product 2 is represented by a two-dot chain line in all the drawings.
The product 2 to be stored is not particularly limited. The blister container 3 of the present invention can store various conventionally known products such as cosmetics, medicines, foods, dry batteries, toys, stationery, electronic devices, and building parts.

The blister container 3 has a cover member 4 and a closing sheet 5.
The cover member 4 is formed from, for example, a synthetic resin sheet. The material of the synthetic resin sheet is not particularly limited, and examples thereof include polyolefins such as polyethylene and polypropylene. The cover member 4 is preferably a sheet having excellent transparency, but may be colored as long as the transparency is not impaired. Moreover, desired printing may be given to the outer surface or a part of inner surface of the cover member 4, or the display label may be affixed.

The cover member 4 is formed with a convex portion 6 protruding outward. A flat flange portion 41 is formed around the convex portion 6 of the cover member 4. In other words, the cover member 4 has a flat flange portion 41 and a convex portion 6 projecting outward within a range surrounded by the flange portion 41. Such a cover member 4 can be obtained by sheet-molding the synthetic resin sheet.
The closing sheet 5 is joined to the inner surface of the flange portion 41. Therefore, as shown in FIG. 4, the opening 42 side corresponding to the convex portion 6 is closed by the closing sheet 5. A gap X and a product storage space Y are formed between the inside of the convex portion 6 and the closing sheet 5.
Specifically, the convex portion 6 includes a first convex portion 61 that can form a gap X between the closed sheet 5 and a second convex that can form a product storage space Y between the closed sheet 56. Part 62. The gap X has a predetermined interval (corresponding to the interval between the top wall 615 of the first convex portion 61 and the closing sheet 5) between a first hanging hole 91 and a second hanging hole 92 described later. It is a space part for holding. The product storage space Y is a space portion for storing the product 2 between the cover member 4 and the closing sheet 5.

  The first convex portion 61 has three peripheral walls (upper wall 611 and left and right side walls 613 and 614) that are raised substantially perpendicular to the flange portion 41, and a ceiling wall that is connected to the end portions of the three peripheral walls. 615. The first convex portion 61 does not have a lower wall, and the lower inside of the first convex portion 61 communicates with the inside of the second convex portion 62. In addition, it is preferable that the top wall 615 of the 1st convex part 61 is a plate shape substantially parallel to the flange part 41, as shown in FIG. However, the top wall 615 of the first convex portion 61 may be formed in an inclined plate shape with respect to the flange portion 41. Moreover, the top wall 615 of the 1st convex part 61 may be formed in circular arc shape, dome shape, and other arbitrary shapes.

  The second convex portion 62 includes four peripheral walls (upper and lower walls 621 and 622 and left and right side walls 623 and 624) that are raised substantially at right angles to the flange portion 41, and a ceiling wall 625 that is connected to the four peripheral walls. And having. However, the upper wall 621 of the second convex portion 62 rises from the top wall 615 of the first convex portion 61, and the upper interior of the second convex portion 62 and the lower interior of the first convex portion 61 communicate with each other. . The shape of the 2nd convex part 62 is suitably set according to the shape of the goods 2 to accommodate. When the cylindrical product 2 as illustrated is stored, the top wall 625 of the second convex portion 62 is formed in an arc plate shape, for example.

  A first hanging hole 91 is formed in the plane of the top wall 615 of the first convex portion 61 (that is, in the plane above the convex portion 6). In the closing sheet 5, a second suspension hole 92 is formed at a position facing the first suspension hole 91 with a gap X. The first suspending hole 91 and the second suspending hole 92 are holes that are inserted into the hanger rod when the blister container 3 is suspended. Of the first suspension hole 91 and the second suspension hole 92, the portion with which the hanger bar contacts when suspended is substantially coincident when viewed from the direction perpendicular to the flange portion 41. Is preferred.

Further, a partition member 7 is integrally extended on the upper edge portion of the cover member 4.
The partition member 7 is a member for dividing the space between the communicating gap portion X and the product storage space portion Y and partitioning the two.
The partition member 7 is provided at a partition wall 71 that partitions the product storage space Y and the gap X, a side wall 72 provided at an end of the partition wall 71, and an end of the partition wall 71 and the side wall 72. And an upper wall 73 and a bridging portion 74 that is continuous with a part of the upper wall 73 and that is continuous with the upper edge of the cover member 4. The side wall 72 of the partition member 7 includes a first side wall 721 raised from the front end portion of the partition wall 71, a second side wall 722 raised from the left end portion of the partition wall 71, and the right end of the partition wall 71. And a third side wall 723 raised from the portion.
As shown by the arrows in FIG. 6, the partition member 7 is bent at the boundary of the cover member 4 and is fitted inside the first convex portion 61. In order to make it easier to bend the partition member 7 at the boundary with the cover member 4, a crease line 75 may be formed at the boundary between the bridging portion 74 and the cover member 4.

In a state where the partition member 7 is fitted inside the first convex portion 61, the front end portion of the partition wall 71 is in contact with (being in line contact with) the top wall 615 of the first convex portion 61. Both end portions are in contact with the lower sides of the left and right side walls 613 and 614 of the first convex portion 61 (in line contact), and the rear end portion 71a of the partition wall 71 is in contact with the closing sheet 5 (in line contact). ). In the same state, the side wall 72 of the partition member 7 is in close contact with the inner surface of the first convex portion 61 (surface contact). More specifically, the first side wall 721 of the partition member 7 is in close contact with (in surface contact with) the inner surface of the top wall 615 of the first convex portion 61, and the second side wall 722 of the partition member 7 is the first convex portion 61. The third side wall 723 of the partition member 7 is in close contact with (in surface contact with) the inner surface of the right side wall 614 of the first convex portion 61. Further, in the same state, the upper wall 73 of the partition member 7 is in close contact with (in surface contact with) the inner surface of the upper wall 611 of the first convex portion 61.
Note that close contact (surface contact) means that both surfaces are in contact with each other to the extent that foreign matter does not enter between the outer surface such as the side wall 72 of the partition member 7 and the inner surface of the first convex portion 61.
The side wall 72 and the upper wall 73 of the partition member 7 have a size that is substantially the same as or slightly larger than the inner surfaces of the left and right side walls 613, 614, the upper wall 611, and the top wall 615 of the first protrusion 61. Is formed. When the partition member 7 is fitted inside the first convex portion 61, the side wall 72 and the upper wall 73 of the partition member 7 are in close contact with the left and right side walls of the first convex portion 61. For this reason, it can prevent that a foreign material penetrate | invades into the goods storage space part Y from between the front-end part of the partition wall 71, a both-ends part, and the inner surface of the 1st convex part 61. FIG.

  Further, a third suspension hole 93 is formed in the surface of the first side wall 721 of the partition member 7. The third suspension hole 93 is closed by the first suspension hole 91 formed in the first projection 61 when the partition member 7 having the first side wall 721 is fitted inside the first projection 61. It is a hole for preventing it from coming off, and is a hole for inserting into the hanger rod, like the first and second suspension holes 92. In the state in which the partition member 7 is fitted, the portion of the third suspension hole 93 that is in contact with the hanger bar during suspension is the first suspension when viewed from the direction perpendicular to the flange portion 41. It is preferable to substantially coincide with the hole 91.

The closing sheet 5 is provided to close the opening 42 corresponding to the convex portion 6 of the cover member 4.
The closing sheet 5 of this embodiment is bonded to the flange portion 41 of the cover member 4 via an adhesive. The closing sheet 5 includes a base sheet and an adhesive layer formed on one surface of the base sheet.
The base sheet is not particularly limited, and for example, single layer sheets such as cardboard, synthetic paper, and synthetic resin sheets, and laminated sheets thereof, and other functional layers (such as metal deposition layers) are laminated on these sheets. Examples include laminated sheets. In addition, in this specification, a sheet | seat is the meaning containing what is generally called the film.
As the base sheet, cardboard, a laminated sheet containing cardboard, a synthetic resin sheet, or a laminated sheet containing a synthetic resin sheet is preferably used. Specifically, the base sheet is preferably, for example, a thick paper having a thickness of about 0.5 mm to 1.5 mm or a laminated sheet thereof, or a synthetic resin sheet having a thickness of about 0.4 mm to 0.8 mm or a laminated sheet thereof.
The base sheet 2 is usually subjected to design printing such as a product name, a pattern, and a product description.

As shown in FIG. 7, the pressure-sensitive adhesive layer only needs to be provided at least in the portion 51 corresponding to the flange portion of the cover member (the portion 51 represented by light ink painting in FIG. 7). Furthermore, the pressure-sensitive adhesive layer may be provided also in a portion 52 corresponding to the opening side corresponding to the convex portion of the cover member (portion 52 represented by shading in FIG. 7). By providing the pressure-sensitive adhesive layer in the portion corresponding to the opening side, the stored product is partially bonded to the pressure-sensitive adhesive layer. Therefore, since the stored product 2 is bonded by the closing sheet 5, the positional deviation of the product 2 can be prevented. By preventing such displacement, the front surface (the surface on which the product name or the like is displayed) of the product 2 can be reliably shown to the consumer through the cover member 4. This is particularly effective when storing a product 2 having a cylindrical shape that can rotate.
Furthermore, the pressure-sensitive adhesive layer may be provided at a portion 53 corresponding to at least the rear end portion of the partition wall of the partition member (the rear end portion 71a shown in FIG. 4) (the portion 53 represented by the oblique lines in FIG. 7). ). As described above, the rear end 71 a of the partition wall 71 of the partition member 7 is in line contact with the closing sheet 5. For this reason, it is difficult for foreign matter to normally enter the product storage space Y from between the rear end 71 a of the partition wall 71 and the closing sheet 5. However, since the flat closing sheet 5 is more easily deformed than the cover member 4 having the convex portion 6, if the rear end portion 71 a of the partition wall 71 and the closing sheet 5 are simply in contact, Along with the deformation, there may be a gap where foreign matter enters between the two. In this respect, the adhesive layer is provided on the portion of the closing sheet 5 corresponding to the rear end portion 71a of the partition wall 71, whereby the rear end portion 71a of the partition wall 71 and the closing sheet 5 are bonded. For this reason, it can prevent reliably that a foreign material penetrate | invades into the goods storage space part Y from between the rear-end part 71a of the partition wall 71, and the obstruction | occlusion sheet 5.
Moreover, the adhesive layer may be provided in the whole surface (one whole surface) of a base sheet. Similarly to the above, the closing sheet 5 provided with the adhesive layer on the entire surface of the base sheet can be bonded to the flange portion of the cover member, a part of the product, and the rear end portion of the partition wall of the partition member. Furthermore, an adhesive layer may be provided on the entire surface of the base sheet, and a concealing layer may be provided in a predetermined range on the adhesive layer. The concealing layer is a layer for concealing the adhesive force of the adhesive. The concealing layer can be formed, for example, by applying printing ink or attaching a film to a predetermined range of one surface of the pressure-sensitive adhesive layer. In the predetermined range where the concealing layer is provided, the adhesive is not exposed. The predetermined range for providing the concealing layer is appropriately set according to the range in which the pressure-sensitive adhesive is exposed. For example, a portion other than the portion indicated by the oblique lines shown in FIG. 7 (that is, the white background portion in FIG. 7) preferable.

  The pressure-sensitive adhesive layer is formed by applying a pressure-sensitive adhesive to a predetermined portion of the base sheet. The pressure-sensitive adhesive is not particularly limited, and examples thereof include a pressure-sensitive pressure-sensitive adhesive that exhibits adhesiveness at room temperature, and a heat-sensitive adhesive that does not exhibit adhesiveness at room temperature and exhibits adhesiveness by heating.

The blister container 3 is used as follows.
That is, after the product 2 is put inside the second convex portion 62 from the opening 42 of the cover member 4 to which the partition member 7 is mounted, the opening 42 is closed with the closing sheet 5 to store the product in the blister container 3. The blister package 1 in which the product 2 is stored in the space Y is obtained.
As shown in FIG. 8, the blister package 1 (blister container 3) passes through the gap X from the second suspension hole 92 to the third suspension hole 93 and the first suspension hole 91. It is suspended by being inserted into the hanger bar Z. Since the first suspending hole 91 and the second suspending hole 92 are opposed to each other with the gap X, the weight of the product 2 is applied to the cover member 4 and the closing sheet 5 that are spaced apart from each other. For this reason, it is possible to prevent the blister container 3 from being inclined downward due to the weight of the stored product 2.
Further, since the gap X and the product storage space Y are formed by the convex portions 6 protruding from the cover member 4, the blister container 3 is curved between the gap X and the product storage space. There is no fear.

  Further, since the partition member 7 that partitions the product storage space Y and the gap X is attached, foreign matter enters the gap X through the first hanging hole 91 and / or the second hanging hole 92. However, this foreign matter can be prevented from entering the product storage space Y. Therefore, it is possible to prevent foreign matter from adhering to the product 2 stored in the product storage space Y of the blister container 3.

  In addition, in the said embodiment, although the partition member 7 is integrally formed with the cover member 4, the partition member 7 and the cover member 4 may be a different body. However, if the partition member 7 and the cover member 4 are integrally formed, they can be simultaneously formed into a sheet, and further, the inside of the convex portion 6 of the cover member 4 can be simply bent at a predetermined position. It is preferable because it can be attached to

  Moreover, in the said embodiment, although the partition member 7 has the partition wall 71, the side wall 72, and the upper wall 73, the partition member 7 should just have the partition wall 71 at least. This is because by separating the gap X and the product storage space Y by the partition wall 71, it is possible to prevent foreign matter that has entered the gap X from entering the product storage space Y. However, the partition member 7 preferably has at least the partition wall 71 and the side wall 72 raised from the end of the partition wall 71. In the partition member 7 in which the side wall 72 is provided on the partition wall 71, the side wall 72 is in surface contact with the inner surface of the convex portion 6, so that the partition wall 71 (partition member 7) is placed in a predetermined position without using an adhesive. Furthermore, it is possible to reliably prevent a gap from entering a foreign object between the end of the partition wall 71 and the inner surface of the convex portion 6.

  Moreover, in the said embodiment, although the partition member 7 is mounted | worn so that the side wall 72 of the partition member 7 may closely_contact | adhere to the inner surface of the 1st convex part 61, it replaces with this and the side wall 72 of the partition member 7 is 2nd. The partition member 7 may be attached so as to be in close contact with the inner surface of the convex portion 62.

  Furthermore, in the said embodiment, although the obstruction | occlusion sheet 5 is adhere | attached on the flange part 41 of the cover member 4 via the adhesive, for example, the obstruction | occlusion sheet 5 adhere | attaches on the flange part 41 of the cover member 4 by heat welding. May be. But it is preferable that the obstruction | occlusion sheet 5 is adhere | attached through the adhesive. When the partition member 7 is formed integrally with the cover member 4, the bridging portion 74 that connects the partition member 7 and the cover member 4 is interposed between the flange portion 41 of the cover member 4 and the closing sheet 5 ( 4), a step corresponding to the thickness of the bridging portion 74 occurs in the flange portion 41. Since the pressure-sensitive adhesive easily enters the stepped portion, it is preferable to bond the closing sheet 5 via the pressure-sensitive adhesive because a gap is hardly generated between the closing sheet 5 and the flange portion 41.

  Furthermore, in the said embodiment, although the obstruction | occlusion sheet 5 is adhere | attached on the flange part 41 of the cover member 4 via an adhesive etc., even if the obstruction | occlusion sheet 5 is provided in the cover member 4 without adhere | attaching. Good. As the blister container 3 of such a modification, for example, as shown in FIG. 9, a cover member 4 in which a flange 45 bent and extended in a hairpin shape from the edge of the flange portion 41 is used. A mode in which the closing sheet 5 is inserted between the portion 41 and the flange portion 45 is exemplified.

  The blister container of the present invention can be used as a packaging container for various products. The blister package in which the product is stored in the blister container can be displayed and sold by hanging it on a hanger bar.
