Description

Plastic uptake package

Technical Field

The present invention relates to a Blister pack (Blister pack).

Background

Blister packs have been widely used as containers for packing articles such as daily necessities, infant and baby products, office supplies, and electric appliances (for example, JP1996-184273 a). Blister packs typically have: a first member having a bulging portion formed at a center thereof for accommodating an article; and a flat second member held at a position facing the first member. The blister pack has a hook formed by forming a hole or a groove, and is displayed by being hung on a display bar. That is, the blister pack is used, and the display can be performed without preparing a shelf on which the packaged product is placed, which contributes to saving of a display space. In particular, hook-type blister packs can be removed from the hanger bar regardless of the display order. Therefore, packaged products of different colors or the like can be displayed using the same display bar, and display space can be more effectively saved.

As a method of fixing the first member and the second member in the blister pack, a thermal fusion method of thermally welding peripheral edges of the first member and the second member has been widely used. As a fixing method other than the thermal welding method, a clamping method is also known in which an edge of the second member is held by a folded-back edge of the first member or the like. The hot melt coating method is not ideal in terms of cost and work efficiency. On the other hand, in a method other than thermal welding such as a pinch method, a gap is formed between the first member and the second member, and foreign matter easily enters the storage space of the article through the gap. Therefore, in specific fields such as daily necessities and infant and baby products that may get into the mouth of a person, blister packs other than the hot melt method have not been used.

Detailed Description

An embodiment of the present invention will be described below with reference to the drawings.

Fig. 1 to 9 are diagrams for explaining an embodiment of the present invention, and show specific examples of the embodiment. The blister package 10 according to the present embodiment includes a first member 20 and a second member 40. A storage space S for storing the object to be packaged is formed between the first member 20 and the second member 40. The blister package 10 is improved so that the second member 40 can be held by the first member 20 by a method other than thermal fusion bonding, and entry of foreign matter into the housing space S can be effectively suppressed.

In the illustrated specific example, the side edge of the second member 40 is clamped by the holding groove 22 formed in the first member 20, whereby the second member 40 can be held on the first member 20 more easily and inexpensively than in the thermal fusion method. Further, the blister pack 10 is formed with a groove 16, and the groove 16 extends through the first member 20 and the second member 40, and has one end opened in a notch shape. A hook 15 capable of hanging the blister pack 10 on the display bar r is formed by the groove 16. As will be described later, the improvement of suppressing the entry of foreign matter into the storage space S employed in the present embodiment can also impart rigidity to the blister package 10. That is, in the conventional blister package other than the heat welding method such as the pinch-in method, the hook method is difficult to be adopted due to the reduction of the rigidity, but in the specific example of the blister package 10 to be described below, the attachment of the second member 40 to the first member 20 can be easily and inexpensively performed, the entry of foreign matter into the housing space S can be effectively suppressed, and the blister package 10 can be provided with rigidity, and the hook 15 can be adopted.

As shown in fig. 1, the illustrated blister pack 10 includes: a first side edge 10a and a second side edge 10 b; a first edge 10c and a second edge 10d extending between the pair of

side edges

10a, 10 b. As shown in fig. 1, the slot 16 opens toward the first edge 10c of the blister package 10. The display rod r can be inserted into the slot 16 through the opening 16 a. Further, the top end 16b of the groove 16 faces the first side edge 10a side. By disposing the display bar r at the position of the distal end 16b and engaging the hook 15 with the display bar r, the blister pack 10 can be stably held so as to be suspended. In the suspended state of the blister pack 10, the first edge 10c forms an upper edge facing upward, and the second edge 10d forms a lower edge facing downward.

Next, the structure of the first member 20 and the second member 40 will be described in order.

The first member 20 includes a first base portion 25, a bent side edge portion 21, and an extension portion 30. In the illustrated example, the first member 20 further includes a swing portion 35. Wherein the first base 25 outlines the blister package 10. On the other hand, the bent side edge portion 21, the extension portion 30, and the swinging portion 35 are provided so as to be expected to exert specific functions, and are connected to the first base portion 25. Typically, the first base portion 25, the bent side edge portion 21, the extension portion 30, and the swinging portion 35 constituting the first member 20 can be integrally formed by processing a single sheet of resin sheet material. In the illustrated example, the first base portion 25 of the first member 20 includes a bulging portion 27 defining the housing space S. Therefore, in order to ensure the visibility of the packaging object in the state of being housed in the blister package 10, the first base portion 25 may be formed to be transparent, or the entire first member 20 may be formed to be transparent. Next, each component of the first member 20 will be described.

As shown in fig. 1, the first base portion 25 has a flat portion 26 connected to a bulging portion 27 in addition to the bulging portion 27 for forming the housing space S. The flat portion 26 has a shape corresponding to a second base portion 45 of the second member 40 described later, for example, a shape capable of surface contact. On the other hand, the bulge portion 27 is away from the second base portion 45 of the second member 40, and a storage space S for storing the packaging object is formed between the bulge portion and the second base portion 45. Therefore, the three-dimensional shape of the bulging portion 27 is appropriately designed according to the shape of the object to be packaged. In the example shown in fig. 1, the bulging portion 27 has a contour forming a quadrangular frustum pyramid-shaped housing space S.

As shown in fig. 2, the flat portion 26 in the illustrated example extends on an imaginary plane. The flat portion 26 surrounds the periphery of the bulging portion 27. As a result, the peripheral edge of the first base portion 25 is defined by the flat portion 26. As shown in fig. 2, the first base portion 25 has: a first side edge 25a and a second side edge 25b extending in a first direction d 1; a first edge 25c and a second edge 25d extending in the second direction d2 between the pair of

side edges

25a, 25 b. In addition, first base 25 includes a defect 29 leading to first edge 25 c. The defective portion 29 forms the slot 16 of the blister pack 10. In the illustrated example, the first direction d1 and the second direction d1 are orthogonal to each other, but the present invention is not limited to this example, and the first direction d1 may be inclined with respect to the second direction d 2.

As shown in fig. 1, the periphery of the blister pack 10 is defined by the first base 25. As shown in fig. 1, the first side edge 10a of the blister pack 10 extends in the first direction d1 along the first side edge 25a of the first base 25, and the second side edge 10b of the blister pack 10 extends in the first direction d1 along the second side edge 25b of the first base 25. The third side edge 10c of the blister pack 10 extends in the second direction d2 along the third side edge 25c of the first base 25 and the fourth side edge 10d of the blister pack 10 extends in the second direction d2 along the fourth side edge 25d of the first base 25.

Next, the bent side edge portion 21 will be explained. The bent side edge portion 21 is connected to the first base portion 25. The bent side edge portion 21 is disposed to face the first base portion 25. That is, the first base portion 25 and the bent side edge portion 21 form a bent portion. The bent side edge portion 21 forms a holding groove 22 with the first base portion 25 as a bent portion. The holding groove 22 accommodates a peripheral edge of a second base 45 of the second member 40 described later.

In the illustrated example, three bending side edge portions 21a, 21b, and 21c are provided as the bending side edge portion 21. The first folded side edge portion 21a is connected to the first side edge 25a of the first base portion 25 and extends elongated in the first direction d 1. The second folded side edge portion 21b is connected to the second side edge 25b of the first base portion 25 and extends in an elongated manner in the first direction d 1. The third folded side edge portion 21c is connected to the second edge 25d of the first base portion 25 and extends elongated in the second direction d 2. The folded side edge portion 21 can be integrally produced with the first base portion 25 by plastically deforming the resin sheet forming the first base portion 25 by a hot press method or the like.

Next, the extension section 30 will be described. The extension 30 is connected to the first base 25 at a part of the periphery of the first base 25. In the illustrated embodiment, as shown in fig. 2, the extension portion 30 is connected to the first base portion 25 at a first edge 25c extending between the pair of

side edges

25a, 25 b. The extension portion 30 is swingable with respect to the first base portion 25. The extension portion 30 is configured to be able to be disposed at a position facing the flat portion 26 of the first base portion 25 by swinging with respect to the first base portion 25 as shown in fig. 1 and 6. That is, the extension portion 30 can be swung with respect to the first base portion 25 to a position overlapping the first base portion 25. As shown in fig. 2 and 5, extension portion 30 is provided with a defect portion 34 as a through opening. As shown in fig. 1 and 6, the defective portion 34 overlaps the defective portion 29 of the first base portion 25 in a state where the extension portion 30 overlaps the first base portion 25. The defective portion 34 of the extension portion 30 forms the slot 16 of the blister package 10 together with the defective portion 29 of the first base portion 25.

As shown in fig. 1 and 6, the extension portion 30 is partially received in the holding groove 22 in a state of being swung onto the first base portion 25. Specifically, in the extension portion 30, both end portions along the second direction d2 can be disposed in the pair of holding grooves 22 in the region away from the first edge 25 c. Therefore, as shown in fig. 5 and 6, the width W of the extension portion 30 in the second direction d2 connecting the pair of

side edges

25a, 25b of the first base portion 25 is shorter than the distance between the pair of

side edges

25a, 25b in a region away from the first edge 25 c. On the other hand, in the region away from the first edge 25c, the width W of the extension portion 30 is equal to or greater than the separation distance dx between the first bending side edge portion 21a and the second bending side edge portion 21b connected to the pair of

side edges

25a, 25 b. Further, the width W of the extension portion 30 is gradually narrowed in a region away from the first edge 25c as it is away from the first edge 25c of the first base portion 25.

As shown in fig. 5, the extension portion 30 shown in the figure includes: an extension connecting portion 31 connected to the first edge 25c of the first base portion 25 in a swingable manner; and an extension body portion 32 connected to the extension connecting portion 31 so as to be capable of swinging. The extension link 31 and the first base portion 25 can swing relative to each other about a first swing axis ds1 located on the first edge 25 c. The extended main body portion 32 and the extended connecting portion 31 can relatively swing around the second swing axis ds2 located on the boundary therebetween. In the illustrated example, the first swing axis ds1 and the second swing axis ds2 are parallel. The length of the extended connecting portion 31 along the first direction d1 is preferably equal to or greater than the thickness of the second base portion 45 of the second member 40 described later.

The extension portion 30 can be integrally formed with the first base portion 25 by using a resin sheet forming the first base portion 25. At this time, the defective portion 29 of the first base portion 25 and the defective portion 34 of the extension portion 30 may be formed by removing a material from a resin sheet by punching, for example. Further, it is preferable that a swing facilitating mechanism for guiding the swing be formed in the resin sheet at the portion of the resin sheet where the first swing axis ds1 and the second swing axis ds2 are formed. The swing promoting mechanism may be a set of through holes provided intermittently in the resin sheet along the swing axes ds3, ds4, a bottomed hole provided continuously along the swing axes ds3, ds4, or a set of a plurality of bottomed holes provided intermittently.

Next, the swinging portion 35 will be explained. The swing portion 35 is connected to the first base portion 25 at a portion 25e adjacent to the groove 16 in the edge of the first base portion 25, that is, at a portion 25e in the edge of the first base portion 25 which defines the groove 16. The swinging portion 35 is swingable with respect to the first base portion 25. The swinging portion 35 can be arranged at a position facing the flat portion 26 of the first base portion 25 as shown in fig. 1 and 5 by swinging with respect to the first base portion 25. That is, the extension portion 30 can swing with respect to the first base portion 25 to a position overlapping the first base portion 25. On the other hand, as shown in fig. 2, the swinging portion 35 can be disposed in the defective portion 29 of the first base portion 25 by swinging with respect to the first base portion 25. That is, the swing portion 35 has a shape that can be disposed in the defective portion 29 of the first base portion 25.

As shown in fig. 2, the swing portion 35 has the same shape as a part of the defective portion 29 of the first base portion 25. When the defective portion 29 is formed from the first base portion 25, the swing portion 35 can be formed as a portion that should be discarded or a part thereof. As shown in fig. 6, in the illustrated example, the groove 16 formed by the defective portion 29 includes: a base end portion 16c extending from the opening 16a on the first edge 10c in the first direction d 1; an intermediate portion 16d extending from the base end portion 16c in the second direction d 2; and a tip portion 16e extending from the intermediate portion 16d in the first direction d1 until the tip 16 b. The illustrated swing portion 35 has a shape in which the intermediate portion 16d and the distal portion 16e of the groove 16 are combined. The swinging portion 35 has a protruding portion 38 protruding in the first direction d1 as a portion corresponding to the tip end portion 16 e.

The swinging portion 35 extends from an edge 25e of the first base portion 25 adjacent to a portion 16d in the slot 16, wherein the portion 16d in the slot 16 extends in a direction that is not parallel to the first direction d 1. In particular, the edge 25e of the first base portion 25 to which the swinging portion 35 is connected defines the groove 16 from the side away from the first edge 25c of the first base portion 25 to which the extension portion 30 is connected, that is, from the side of the second edge 25 d. In the illustrated example, the edge 25e of the first base portion 25 to which the swinging portion 35 is connected is located on the opposite side of the first edge 25c in the first direction d1, that is, on the side of the second edge 25d in the first direction d1, of a pair of edges of the first base portion 25 that are adjacent to the intermediate portion 16d in the slot 16 and extend in the second direction d 2. The edge 25e is located in the first direction d1 in a region where the first folded side edge portion 21a and the second folded side edge portion 21b are provided.

As shown in fig. 6, the extension portion 30 pivoted to the first base portion 25 and the pivoting portion 35 pivoted to the first base portion 25 at least partially overlap each other in a region closer to the second edge 25d than the first base portion 25 in the first direction d 1.

As shown in fig. 2, the illustrated swing portion 35 includes: a swing connecting portion 36 connected to the edge 25e of the first base portion 25 in a swingable manner; and a swing body 37 connected to the swing connection 36 in a swingable manner. The swing connecting portion 36 and the first base portion 25 can swing relative to each other about a third swing axis ds3 located on the edge 25 e. The swing main body portion 37 and the swing connecting portion 36 can swing relative to each other about a fourth swing axis ds4 located on the boundary therebetween. In the illustrated example, the third swing axis ds3 and the fourth swing axis ds4 are parallel. The length of the swing connecting portion 36 along the first direction d1 is preferably equal to or greater than the thickness of the second base portion 45 of the second member 40 described later.

The swing portion 35 can be integrally formed by forming a fold along the defective portion 29 in the resin sheet forming the first base portion 25 as described above. Further, it is preferable that a swing facilitating mechanism for guiding the swing be formed in the resin sheet at the portion of the resin sheet where the third swing axis ds3 and the fourth swing axis ds4 are formed. The swing facilitating mechanism may be a set of through holes provided intermittently along the swing axes ds3, ds4 in the resin sheet, or a bottomed hole or a set of bottomed holes provided intermittently or continuously along the swing axes ds3, ds4 in the resin sheet.

Next, the second member 40 will be explained. The second member 40 has a second base portion 45, and the second base portion 45 is disposed so as to overlap the first base portion 25 in a state where the second member 40 is held by the first member 20.

In the illustrated example, the second base portion 45 has the same planar shape as the first base portion 25. As shown in fig. 3, the second base 45 includes: a first side edge 45a and a second side edge 45 b; a first edge 45c and a second edge 45d extending between the pair of

side edges

45a, 45 b. In a state where the second member 40 is held by the first member 20, the first side edge 45a and the second side edge 45b of the second base portion 45 face the first side edge 25a or the second side edge 25b of the first base portion 25, respectively, and extend in the first direction d 1. In addition, in a state where the second member 40 is held by the first member 20, the first edge 45c and the second edge 45d of the second base portion 45 face the first edge 25c or the second edge 25d of the first base portion 25, respectively, and extend in the second direction d 2.

In addition, second base 45 includes a defect 49 that opens to first edge 45 c. The defective portion 49 forms the groove 16 of the blister pack 10 together with the defective portion 29 of the first base portion 25 and the defective portion 34 of the extension portion 30. The defective portion 49 of the second base portion 45 has the same shape as the defective portion 29 of the first base portion 25.

As shown in fig. 3, the second base portion 45 in the illustrated specific example does not include a bulging portion, and is formed only by the flat portion 46. The flat portion 46 extends in a plane. However, without being limited to this example, the second base 45 may include a bulging portion instead of or in addition to the bulging portion 27 of the first base 25.

The second member 40 is made of, for example, a resin sheet. However, as shown in the illustrated example, when the second member 40 is formed only by the planar second base portion 45, it can be manufactured using paper, particularly thick paper. The second base 45 and the second member 40 made of paper or the like are preferable in that various decorations can be easily performed by printing or the like.

Next, a procedure of assembling the first member 20 and the second member 40 having the above-described structure to produce the blister package 10 will be described.

First, the object to be packaged is accommodated in the bulging portion 27 of the first member 20. At this time, as shown in fig. 2, the extension portion 30 is disposed at a position not overlapping with the first base portion 25 in the first direction d 1. That is, the first base portion 25 and the extension portion 30 are arranged offset in the first direction d 1. The swinging portion 35 is also disposed at a position not overlapping with the first base portion 25, in other words, within the defective portion 29 of the first base portion 25. Next, as shown in fig. 4, the second member 40 is positioned on the first member 20 such that the pair of

side edges

45a, 45b of the second base portion 45 are positioned in the holding groove 22 formed by the first base portion 25 and the first and second bent side edge portions 21a, 21 b. At this time, the end portion of the

side edges

45a, 45b of the second base 45 on the second edge 45d side is inserted into the end portion of the holding groove 22 on the first edge 25c side.

Thereafter, as shown in fig. 4, the second member 40 is relatively moved in the first direction d1 with respect to the first member 20. Finally, the second edge 45d of the second base portion 45 is received in the holding groove 22 formed by the first base portion 25 and the third folded side edge portion 21 d. At this time, the second base portion 45 and the first base portion 25 overlap each other, and the pair of

side edges

45a, 45b, the first edge 45c, and the second edge 45d of the second base portion 45 overlap the pair of

side edges

25a, 25b, the first edge 25c, or the second edge 25d of the first base portion 25, respectively. The defective portion 49 formed in the second base portion 45 and the defective portion 29 formed in the first base portion 25 are overlapped with each other.

Next, as shown in fig. 5, the swing portion 35 is swung with respect to the first base portion 25. More specifically, the swinging portion 35 is swung with respect to the first base portion 25 such that the second base portion 45 is positioned between the swinging portion 35 and the first base portion 25 (as in the positional relationship shown in fig. 7). Accordingly, the first member 20 and the second member 40 can be restricted from moving relatively in the first direction d 1. In addition, the gap between the first member 20 and the second member 40 is closed by the swinging portion 35.

The illustrated swing portion 35 includes: a swing connecting portion 36 connected to the first base portion 25 so as to be swingable about a third swing axis ds 3; and a swing body 37 connected to the swing connection 36 so as to be swingable about a fourth swing axis ds 4. As shown in fig. 7, the swing connecting portion 36 has a predetermined length, and preferably, the swing connecting portion 36 has a length equal to or greater than the thickness of the second base portion 45, so that the first member 20 can be stably bent while the second base portion 45 having a predetermined thickness is sandwiched therebetween.

Thereafter, as shown in fig. 6 and 7, the extension portion 30 is swung with respect to the first base portion 25. More specifically, the extension portion 30 is swung with respect to the first base portion 25 so that the second base portion 45 is located between the extension portion 30 and the first base portion 25. Accordingly, the first member 20 and the second member 40 can be restricted from moving relatively in the first direction d 1. In addition, the gap between the first member 20 and the second member 40 is closed by the extension portion 30.

The illustrated extension portion 30 includes: an extension connecting portion 31 connected to the first base portion 25 so as to be swingable about a first swing axis ds 1; and an extension main body portion 32 connected to the extension connecting portion 31 so as to be swingable about a second swing axis ds 2. As shown in fig. 7, the extension connecting portion 31 has a predetermined length, and preferably, the extension connecting portion 31 has a length equal to or greater than the thickness of the second base portion 45, so that the first member 20 can be stably bent while the second base portion 45 having a predetermined thickness is held therebetween.

As shown in fig. 6, a region of the extension portion 30, which is located on a side away from the first edge 25c in the first direction d1 and which becomes two edge portions in the second direction d2, is inserted into the holding groove 22 formed by the first base portion 25 and the first and second bent side edge portions 21a and 21 b. Accordingly, the extension portion 30 can be restricted from swinging with respect to the first base portion 25. At this time, as shown in fig. 7, the extension portion 30, the swinging portion 35, the second base portion 45, and the first base portion 25 are overlapped in this order in a region adjacent to the groove 16 from the opposite side to the hook 15 side. Further, since the extension portion 35 is restricted from swinging with respect to the first base portion 25, the swinging of the swinging portion 35 with respect to the first base portion 25 is also restricted.

Through the above steps, the second member 40 can be held by the first member 20, and thus the packaged product P in which the packaging object is housed in the blister package 10 can be obtained. The extension portion 30 and the swinging portion 35 may be fixed to the first base portion 25 using a tape or the like as necessary. The blister pack 10 is hung by hanging the hanger 15 from the display bar r. At this time, the first edge 10c of the blister package 10 is positioned on the upper side in the vertical direction, and the second edge 10d of the blister package 10 is positioned on the lower side in the vertical direction.

In the above-described embodiment, the blister pack 10 includes the first member 20 and the second member 40 held by the first member 20, and the storage space S is formed between the first member 20 and the second member 40. The first member 20 has: a first base portion 25; and an extension portion 30 connected to the first edge 25c of the first base portion 25 in a swingable manner. The second member 40 has a second base portion 45, and the second base portion 45 is disposed so as to overlap the first base portion 25 in a state of being held by the first member 20. The groove 16 that penetrates the extension portion 30, the second base portion 45, and the first base portion 25 and extends to the peripheral edge 10c of the blister package 10 is provided in a state where the extension portion 30 is swung with respect to the first base portion 25 so that the second base portion 45 is positioned between the extension portion 30 and the first base portion 25. Further, a hook 15 for hanging the blister pack 10 is formed by the extension portion 30, the second base portion 45, and the first base portion 25 at a position adjacent to the groove 16.

According to the present embodiment as described above, the hook 15 includes the extension portion 30 of the first member 20 in addition to the first base portion 25 of the first member 20 and the second base portion 45 of the second member 40. Accordingly, the hook 15 has sufficient rigidity and can be stably hung on the display bar r. In the first edge 10c of the blister pack 10 which faces upward in a state of being suspended from the display bar r, the gap between the first member 20 and the second member 40 is closed by the extension portion 30 of the first member 20 (fig. 7). Therefore, the extension portion 30 can effectively prevent foreign matter such as dust from entering the housing space S formed between the first member 20 and the second member 40. That is, the blister package 10 in which the first member 20 and the second member 40 are not sealed by the hot melt method or the like, for example, the pinch-type blister package 10 in which the second member 40 is held by the first member 20 by the holding groove 22 of the first member 20 can be stably hung on the display stick r using the hook 15, and entry of foreign matter into the housing space S can be effectively suppressed. As a result, blister packs other than the hot melt method can be applied to the fields of daily necessities and infant products (for example, chopsticks, particularly chopsticks for infants) which have been considered to be difficult to apply in the past and which may possibly enter the mouth of a person.

In addition, in the above-described specific example, the first base portion 25 further includes a pair of

side edges

25a, 25b, and the pair of

side edges

25a, 25b are located on both sides of the first edge 25c to which the extension portion 30 is connected. The first member 20 further has a bent side edge portion 21, and the bent side edge portion 21 is connected to the first base portion 25 at least one of the pair of

side edges

25a, 25b and forms a holding groove 22 with the first base portion 25. The second member 40 is held by the first member 20 by the

side edges

45a, 45b of the second base 45 being disposed in the holding groove 22. A part of the extension portion 30 is disposed in the holding groove 22 in a state where the extension portion 30 is swung with respect to the first base portion 25 so that the second base portion 45 is positioned between the extension portion 30 and the first base portion 25. According to this example, the extension portion 30 can be maintained in a state of closing the gap between the first member 20 and the second member 40, which is communicated with the housing space S, by using the holding groove 22. The holding groove 22 is provided for the purpose of holding the second member 40 by the first member 20, and by using the holding groove 22, it is possible to effectively suppress the entry of foreign matter into the housing space S without increasing the number of members. Further, since the blister pack 10 is stable, the rigidity of the hook 15 can be increased and the hook can be stably hung on the display bar r.

In the above-described specific example, the first member 20 further has a pair of bent side edge portions 21a, 21b, and the pair of bent side edge portions 21a, 21b are connected to the first base portion 25 at each of the pair of

side edges

25a, 25b and form the holding grooves 22 with the first base portion 25. The second member 40 is held by the first member 20 by the pair of

side edges

45a, 45b of the second base 45 being disposed in the holding groove 22. The width W of the extension portion 30 in the direction connecting the pair of

side edges

25a, 25b of the first base portion 25 becomes narrower away from the first edge 25c of the first base portion 25 in a region away from the first edge 25c in the first direction d1, more specifically, in a part of the region in the first direction d1 including the portion housed in the holding groove 22. According to this example, the extension portion 30 can be easily inserted into the holding groove 22.

Further, since the second base portion 45 has a thickness, the extension portion 30 that swings to a position where the second base portion 45 is sandwiched between the first base portion 25 and the second base portion 45 easily swings away from the second base portion 45. However, in the above-described specific example, the extension portion 30 has: an extension connecting portion 31 connected to the first base portion 25 so as to be swingable; and an extension body portion 32 connected to the extension connecting portion 31 so as to be capable of swinging. Since the extension connecting portion 31 has a certain length, preferably a length equal to or greater than the thickness of the second base portion 45, the extension portion 30 can be effectively prevented from swinging away from the second base portion 45.

Further, in the case where the groove 16 for forming the hook 15 is provided, there is a possibility that: at a position adjacent to the groove 16, a gap that opens into the housing space S is opened between the first member 20 and the second member 40. In contrast, according to the above-described specific example, the first member 20 has the swinging portion 35, and the swinging portion 35 is swingably connected to the first base portion 25 at the edge 25e of the first base portion 25 adjacent to the groove 16. The extension portion 30 can be swung with respect to the first base portion 25 such that the second member 40 is positioned between the swing portion 35 and the first base portion 25. The extension portion 30 can close a gap formed between the first member 20 and the second member 40 at a position adjacent to the groove 16. Therefore, it is possible to more effectively suppress the entry of foreign matter into the housing space S formed between the first member 20 and the second member 40. In the above example, the swing portion 35 is formed by leaving the portion 35 that should be discarded. Further, by providing the swing portion 35, the rigidity of the vicinity of the groove 16 defining the hook 15 can be improved.

In the above-described specific example, the edge 25e of the first base portion 25 to which the swinging portion 35 is connected is located on the side away from the first edge 25c of the first base portion 25 to which the extended portion 30 is connected with respect to the slot 16. That is, the swing portion 35 can close a gap facing upward in a state where the blister package 10 is hung on the display bar r, of the gap between the first member 20 and the second member 40 adjacent to the groove 16. Accordingly, it is possible to more effectively suppress the entry of foreign matter into the housing space S formed between the first member 20 and the second member 40.

In the above-described specific example, the edge 25e of the first base portion 25 to which the extension portion 30 is connected is disposed in the region where the bent side edge portion 21 is provided in the direction in which the pair of

side edges

25a, 25b of the first base portion 25 extend. In the region where the folded side edge portion 21 is provided, the second base portion 45 is held in the holding groove 22, and therefore, the gap between the first member 20 and the second component 40 is not easily opened largely. Accordingly, it is possible to more effectively suppress the entry of foreign matter into the housing space S formed between the first member 20 and the second member 40.

Further, since the second base portion 45 has a thickness, the swing portion 35 swung to a position where the second base portion 45 is sandwiched between the first base portion 25 and the swing portion is easily swung so as to be separated from the second base portion 45. However, in the above-described specific example, the swing portion 35 has: a swing connecting portion 36 connected to the first base portion 25 so as to be capable of swinging; and a swing body 37 connected to the swing connection 36 in a swingable manner. The swing connecting portion 36 has a certain length, preferably a length equal to or greater than the thickness of the second base portion 45, and therefore, the swing portion 35 can be effectively suppressed from swinging away from the second base portion 45.

In the above-described specific example, the extension portion 30 is swung with respect to the first base portion 25 so that the second base portion 45 is positioned between the extension portion 30 and the first base portion 25, and the swinging portion 35 is swung with respect to the first base portion 25 so that the second base portion 45 is positioned between the swinging portion 35 and the first base portion 25, and in this state, the extension portion 30 and the swinging portion 35 are at least partially overlapped. According to such an example, the other of the extension portion 30 and the swinging portion 35 can be restricted from swinging with respect to the first base portion 25 by fixing either of the extension portion 30 and the swinging portion 35 so as not to swing with respect to the first base portion 25, for example, by fixing with the holding groove 22, the tape, or the like.

In the above-described specific example, the extension portion 30, the swing portion 35, the second base portion 45, and the first base portion 25 are overlapped with each other in this order in at least a part of the blister pack 10. According to such an example, the extended portion 30 is processed so as not to swing with respect to the first base portion 25, and the swinging portion 35 can be restricted from swinging with respect to the first base portion 25 by holding the extended portion 30 by the holding groove 22, for example.

In the above description, an embodiment has been described with reference to specific examples shown in the drawings, but these specific examples are not intended to limit the embodiment. The above-described embodiment can be implemented by various other specific examples, and various omissions, substitutions, and changes can be made without departing from the spirit thereof.

Hereinafter, a modified example will be described with reference to the drawings. In the following description and the drawings used in the following description, the same reference numerals as those used for the corresponding parts in the above-described specific example are used for the parts that may have the same structure as the above-described specific example, and the duplicated description is omitted.

In the above-described specific example, the groove 16 is shown as an example of the peripheral edge of the blister pack 10 opening toward the first edge 25c, but the present invention is not limited thereto. For example, the slot 16 may be open to the first side edge 25a as a peripheral edge of the blister pack 10. The groove 16 may be opened to the first side edge 25a and the first edge 25c as a peripheral edge of the blister pack 10, and the portion a in fig. 1 may be deleted.

In the above-described specific example, the example in which the swinging portion 35 swings before the extension portion 30 is shown, but the present invention is not limited to this. For example, the following structure may be adopted: as shown in the example shown in fig. 8 and 9, after the second member 40 is held by the first member 20 by the holding groove 22, the extension portion 30 is first swung with respect to the first base portion 25 so that the second base portion 45 is positioned between the extension portion 30 and the first base portion 25. When the extension portion 30 swings, the swing portion 35 is disposed in the defect portion 29 of the first base portion 25 (the position of the swing portion 35 in fig. 2). After the extension portion 30 is swung, the swinging portion 35 swings with respect to the first base portion 25 so that the second base portion 45 is located between the swinging portion 35 and the first base portion 25.

In this example, as shown in fig. 9, the swinging portion 35, the extended portion 30, the second base portion 45, and the first base portion 25 are overlapped in this order in a region adjacent to the groove 16 from the opposite side to the hook 15 side. According to such an example, the swinging portion 35 is fixed so as not to swing with respect to the first base portion 25, and the swinging portion 35 is fixed to the first base portion 25 using, for example, a tape or the like, whereby the swinging of the extension portion 30 with respect to the first base portion 25 can be also restricted.

Further, in the example shown in fig. 8 and 9, the swinging portion 35 has a protruding portion 38, and the protruding portion 38 protrudes toward a side away from the first edge 25c of the first base portion 25. On the other hand, the extension portion 30 is provided with a hole 33 into which the protrusion 38 can be inserted. The protruding portion 38 of the swinging portion 35 is inserted into the hole 33 of the extension portion 30. Further, since the swinging portion 35 is biased in the first direction d1 from the extension portion 30 with respect to the swinging axes ds3, ds4 of the first base portion 25 with respect to the swinging axes ds1, ds2 of the first base portion 25, by inserting the protruding portion 38 into the hole 33, it is possible to restrict both the swinging of the swinging portion 35 with respect to the first base portion 25 and the swinging of the extension portion 30 with respect to the first base portion 25. According to such an example, the swinging portion 35 can be stably and easily fixed to the extension portion 30. As a result, the extension portion 30 and the swinging portion 35 are restricted from freely swinging with respect to the first base portion 25. Accordingly, the foreign matter can be effectively prevented from entering the storage space S. Further, since the rigidity of the blister package 10 near the hook 15 can be effectively increased, the blister package 10 can be more stably hung on the display bar r.

In the above-described specific example, the swing portion 35 has a shape in which the intermediate portion 16d and the distal end portion 16e of the groove 16 are combined, but is not limited to this. For example, the swing portion 35 may have a shape in which the base end portion 16c and the intermediate portion 16d are combined, or may have a shape in which the base end portion 16c, the intermediate portion 16d, and the tip end portion 16e are combined. In any shape, the swing portion 35 can be formed using a portion that should be discarded in order to form the defective portion 29 forming the groove 16, and therefore, the material can be used effectively and the rigidity can be improved advantageously.

In the above example, the first member 20 and the second member 40 are made of different members, but the present invention is not limited to this. For example, the following structure may be adopted: the second side edge 25b of the first base portion 25 and the second side edge 45b of the second base portion 45 are connected to be capable of swinging, and the second member 40 is held by the first member 20 by inserting the first side edge 45a of the second base portion 45 into the holding groove 22 formed between the first base portion 25 and the first bent side edge portion 21 a. According to such an example, it is also possible to effectively suppress the entry of foreign matter into the housing space S by closing the gap between the first member 20 and the second member 40 with the extension portion 30 and the swinging portion 35. Further, the rigidity of the hook 15 can be improved by the second member 40.

Further, the blister pack 10 according to another embodiment includes the first member 20 and the second member 40 held by the first member 20, and the housing space S is formed between the first member 20 and the second member 40. The first member 20 has: a first base portion 25; and an extension portion 30 connected to the first edge 25c of the first base portion 25 in a swingable manner. The second member 40 has a second base portion 45, and the second base portion 45 is disposed so as to overlap the first base portion 25 in a state of being held by the first member 20. In a state where the extension portion 30 is swung with respect to the first base portion 25 so that the second base portion 45 is positioned between the extension portion 30 and the first base portion 25, a hanging hole 17 (a two-dot chain line in fig. 1) or a groove 16 penetrating the extension portion 30, the second base portion 45, and the first base portion 25 is provided.

According to the blister pack 10 of the other embodiment, the

defect portions

29, 34, 49 for forming the hole 17 or the groove 16 are formed in the extension portion 30 of the first member 20 in addition to the first base portion 25 of the first member 20 and the second base portion 45 of the second member 40. Accordingly, the blister pack 10 is also sufficiently rigid around the aperture 17 or the slot 16. As a result, the blister pack 10 can be stably suspended by inserting the display bar r through the hole 17 or the groove 16. In the first edge 10c of the blister pack 10 which faces upward in a state of being suspended from the display bar r, the gap between the first member 20 and the second member 40 is closed by the extension portion 30 of the first member 20. Therefore, it is possible to effectively suppress the entry of foreign matter such as dust into the housing space S formed between the first member 20 and the second member 40. That is, the unsealed blister package 10 such as the hot melt method can stably suspend the first member 20 and the second member 40 from the display stick r, for example, the pinch-type blister package 10 in which the second member 40 is attached to the first member 20 by the holding groove 22 of the first member 20, and entry of foreign matter into the housing space S can be effectively suppressed. As a result, blister packs other than the hot melt method can be applied to the fields of daily necessities, infant products, and the like, which have been conventionally considered to be difficult to apply to clip-type blister packs and which may enter human mouths.
