Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blister pack having a plurality of storage portions between two sheets.

[0002]

2. Description of the Related Art A paperboard and a transparent plastic sheet having about three to ten continuous domes formed in a dome shape by vacuum forming or the like are commercialized by sealing after storing the articles in the receiving parts. The so-called blister pack type packaging form has a high store display effect because multiple contents can be seen through the dome-shaped plastic sheet,
Small items such as toothbrush, interdental brush, floss pick,
It is often used as a retail container for oral hygiene products such as floss. FIG. 4 shows an example of a conventional blister pack for a toothbrush. As shown in the layer configuration in a dotted box P in FIG. 4, this blister pack is made of a board 5 made of paperboard or the like.
1 and a dome sheet 52 made of transparent plastic are superimposed, and their peripheral portions 53 are sealed with each other.
The partition part 55 between the adjacent storage parts 54, 54 is also sealed integrally with the seal of the peripheral part 53 so that the articles 1 are stored in the independent storage parts 54, respectively.

[0003] In recent years, demands for resource saving and environmental preservation have increased, and as for blister packs, it has been required to reduce the use of plastic sheets and paperboard in manufacturing plants and to recycle used resources. What was noticed here was the width of the partition part 55 of the adjacent storage part,
In order to seal the partition portion 55 using a sealer type integral with the peripheral portion 53, a width of about 5 mm to 10 mm is required. Therefore, the required amount of the backing sheet 51 and the dome sheet 52 per blister pack is reduced. More
In addition, large display spaces were needed even at stores. Further, when the used blister pack is collected to separate the backing sheet and the dome sheet, it is difficult to separate the backing sheet because the partitioning portion 55 is sealed. Thus, as shown in FIG. 5, a resource-saving blister pack in which the seal of the partition portion 55 is eliminated to reduce the partition width and seal only the peripheral portion 53 has come to be used. In addition, when considering recycling of the used blister pack, the seal of the partition portion 55 is removed so that the backing sheet 51 and the dome sheet 5 are removed.
There was also recognized an advantage that separation and recovery from No. 2 were facilitated.

[0004]

However, the resource-saving blister pack having the above-described structure can be transported or displayed in stores when a product having a brush or a needle-like tip such as a toothbrush, an interdental brush, or a floss pick is stored. When the blister pack bends inside, as shown in FIG. 6, a gap is formed in the partition part 55 of the storage part, and the brush 2 and the needle-like tip part may enter the partition part 55 and be caught. If the brush 2 is left for a long time while being sandwiched between the partitioning portions 55, the "guzzle" in the sandwiched state will remain until later, and the commercial value will be reduced and the store display effect will also be reduced. In the case of a floss pick having a needle-like tip, the needle-like tip is also used as the partition 55.
It is easy to be pinched, and if it is pinched, the tip will be deformed or the blister pack will be damaged, reducing the display effect at the store. SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and accordingly, has as its object to provide a resource-saving blister pack in which stored articles are not pinched by partitions of the storage section. is there.

[0005]

According to the present invention, there is provided a blister pack in which a plurality of storage portions are formed between two sheets, wherein a peripheral portion of the two sheets is provided. Provide a blister pack that is sealed from one another and the partition between adjacent storage portions is partially sealed. In this blister pack, since the partition between the adjacent storage portions is partially sealed, by selecting the position to be sealed according to the shape of the article to be stored, the space between the partition portions due to bending or the like is determined. Even if the part is partially opened, the brush or the needle-like tip part does not enter into the partition part and is caught, thereby maintaining the commercial value. Further, by selecting the position where the partition section is sealed, the width of the partition section can be reduced, the area of the entire blister pack can be reduced, and resources can be saved. Furthermore, since the partition part is only partially sealed, peeling is facilitated at the time of separating and collecting two sheets in the used blister pack.

It is preferable that the article contained in the blister pack of the present invention has a brush or fiber attached to an end or a needle or leaf shaped end. A toothbrush, an interdental brush, a floss pick, a floss, an ear cleaning tool, a nail cleaning tool, and the like have a brush or fiber attached to an end thereof, or have a needle-like or leaf-like end. In particular, in the case of conventional resource-saving blister packs, these articles have a high possibility of being caught in the end portion by the partition, and the use of the blister pack of the present invention prevents deformation even during transportation or in stores. And maintain the commercial value.

In the above, it is preferable that at least one end of the partition is sealed. toothbrush,
A brush is implanted at one end of an interdental brush or the like, and a needle-like tip in a floss pick or the like is also formed at one end. Therefore, as long as at least the partition portion of the brush or the needle-like tip portion is sealed, there is no possibility that the brush or the needle-like tip portion is pinched by the partition portion even if the other portions are not sealed.

[0008] It is preferable that the length of the non-seal portion in the partition portion is shorter than the length of the articles stored in the storage portion. Thus, even if the article to be accommodated is formed into a needle-like or leaf-like shape and easily enters the gap between the partitions, there is no possibility of entering the gap between the partitions.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings. [First Embodiment] FIG. 1 shows a blister pack according to a first embodiment. The article contained in the blister pack 10 is a toothbrush 1. The toothbrush 1 includes a brush 2, a flocked portion 3 on which the brush 2 is planted, a neck 4 integrally extending from the brushed portion 3, and a neck 4. And a handle portion 5 integrally extending from the portion 4. The neck 4 is formed thinner than the flocked portion 3 and the handle portion 5 and has elasticity. The handle part 5 is formed to be slightly thick and long so as to be adapted to the grasped hand.

The blister pack 10 is formed so as to accommodate three toothbrushes 1 in parallel, and as shown in a layered structure in a dotted line box P in FIG. 1, a backing sheet 11 made of paperboard and a transparent sheet superposed thereon. And a dome sheet 12 made of a plastic sheet. In the dome sheet 12,
Domes 13 which are concave portions for accommodating the toothbrushes 1 one by one are formed, and between adjacent domes, partition portions 17 which are flat portions remaining without being dome are formed.

Each of the domes 13 has a brush housing portion 14 for accommodating the brush 2 and the flocked portion 3 formed therein so that the toothbrush 1 can be accommodated in a side view, and a neck accommodating portion for accommodating the neck portion 4. Numeral 15 is formed to be thin corresponding to the diameter of the neck, and the grip housing 16 for storing the grip 5 is formed to be wide corresponding to the diameter of the grip. In addition, the blister pack 10 has a hanging portion 40 formed above the brush accommodating portion 14 so that the blister pack 10 can be hung on a nail or the like for display at a store.

The mount 11 and the dome sheet 12 have the peripheral portion 18 and the hanging portion 40 surrounding all of the juxtaposed domes 13 in a state where the toothbrush 1 is accommodated in all the domes 13. Heat sealed and integrated. In addition, the mount 11 and the dome sheet 12 of the blister pack 10
The neck 19 is also heat-sealed at the projection 19 which is inevitably caused by the relatively narrow shape of the neck housing 15.

In the blister pack 10 of the first embodiment,
Excluding the relatively wide projection 19, the partition 17
Is not heat-sealed, so no extra width is required for heat-sealing, and thus the overall width of the blister pack can be made smaller compared to a conventional blister pack whose partitions are heat-sealed over its entire width. Can save resources.

On the other hand, since the protruding portion 19 which is a part of the partition portion is heat-sealed, the blister pack may be bent and the space between the mount 11 and the dome sheet 12 of the partition portion may open in the brush accommodating portion 14. However, the movement of the neck 4 of the toothbrush is restricted by the heat sealing of the protruding portion 19, and the brush 2 does not come into contact with the partition of the brush accommodating portion 14. It is not sandwiched between. Also, even if the brush 2 may come into contact with the partitioning portion 17, since the side portion of the neck storage portion 15 adjacent to the brush storage portion 14, that is, the projecting portion 19, is heat-sealed, the mount 11 and the dome Sheet 12
Does not open so much that the brush 2 enters, and therefore the brush 2 is not pinched. In addition, since the partition is only partially sealed, it is easy to separate and collect two sheets in the used blister pack.

Second Embodiment FIG. 2 shows a blister pack according to a second embodiment. Articles contained in the blister pack 20 are the interdental brushes 6, the interdental brushes 6, the brushes 7, the flocked shafts 8 on which the brushes 7 are planted, and the handle portions 9 that extend by embedding the flocked shafts 8. It consists of The flocking shaft 8 is formed by twisting wires woven with the brush 7. The handle portion 9 is made of plastic, and the handle portion is picked up, the brush 7 is inserted between the teeth, and the attached matter is scraped out.

The blister pack 20 is formed so as to accommodate ten interdental brushes 6 in this example in parallel, and comprises a mount 21 made of paperboard and a dome sheet 22 made of a transparent plastic sheet stacked thereon. It is configured. Domes 23, which are recesses for accommodating the interdental brushes 6, one by one, are formed in the dome sheet 22, and between adjacent dome portions, partition portions, which are flat portions left without being recessed. 27 are formed.

Each dome 23 is formed in a semi-cylindrical shape having a U-shaped cross section. In addition, the blister pack 20 is formed with a hanging portion 40 at an upper portion so that the blister pack 20 can be hung on a nail or the like for display at a store.

The mount 21 and the dome sheet 22 are arranged such that the interdental brush 6 is accommodated in all the domes 23, and the peripheral portion 28 and the hanging portion 40 surrounding all the juxtaposed domes 23. Are heat-sealed and integrated. Further, the mount 21 and the dome sheet 22 of the blister pack 20 are separated from the peripheral portion 28 of the partition portion 27.
Are also heat-sealed at both ends 29A, 29B extending from the end. At this time, the central portion of the partition portion 27 is a non-seal portion 27A. The length of the non-seal portion 27A is shorter than the total length of the interdental brush 6 accommodated.

In the blister pack 20 of the second embodiment,
Since both ends 29A and 29B of the partition portion 27 are heat-sealed, the blister pack bends and the unsealed portion 27A of the partition portion 27 mounts the mount 11 and the dome sheet 12.
However, the brush 7 of the interdental brush is located at the end of the dome 23, so that the brush 7 is not sandwiched between the mount 21 and the dome sheet 22. At this time, even if the interdental brush 6 is offset to one side in the dome 23, the length of the non-seal portion 27A in the partition portion 27 is shorter than the entire length of the interdental brush 6 housed in the dome. Also, the brush 7 is not sandwiched between the mount 21 and the dome sheet 22. In addition, since the partition is only partially sealed, it is easy to separate and collect two sheets in the used blister pack.

Third Embodiment FIG. 3 shows a blister pack according to a third embodiment. The articles contained in the blister pack 30 are frost picks 41 and the frost picks 4
1 includes a floss (twisted yarn for cleaning between teeth) 42, a holding portion 43 for holding both ends of the floss, and a toothpick-like pick portion 44 extending from the holding portion. Holder 43
The pick 44 is integrally formed of plastic, and the tip of the pick 44 is pointed like a needle. The floss pick 41 inserts the floss 42 between the teeth to scrape out the extraneous matter, or protrudes the extraneous matter to the tooth at the tip of the pick 44.

The blister pack 30 includes a floss pick 4
1 is formed so as to accommodate 24 cells in parallel, and is composed of a mount 31 made of a heat-sealable cellophane sheet and a dome sheet 32 made of a transparent plastic sheet stacked thereon. Domes 33 are formed in the dome sheet 32 as concave portions for accommodating the frost picks 41 one by one. Between adjacent dome portions, partition portions 37 which are flat portions left without being concave portions are formed.
... are formed. Each dome 33 is formed in a semi-cylindrical shape having a U-shaped cross section.

With the frost pick 41 accommodated in all the domes 33, the mount 31 and the dome sheet 32 are heat sealed at the peripheral portion 38 surrounding all of the juxtaposed domes 33 and are integrated. . The mount 31 and the dome sheet 32 of the blister pack 30 are also heat-sealed at two points 39A and 39B in the middle of the partition 37. This sealed two points 39A, 3
9B are provided at positions near both ends of the partition portion 37, respectively. The central portion of the partition portion 37 is a non-seal portion 37A.
The length of the non-seal portion 37A is shorter than the entire length of the frost pick 41 accommodated therein.

In the blister pack 30 of the third embodiment,
Since the partition 37 is heat-sealed at two points 39A and 39B close to both ends, the blister pack may bend and the space between the mount 31 and the dome sheet 32 may open at the non-seal portion 37A of the partition 37. Even if there is, the pick part 44 of the floss pick 41 or the tip of the pick part 44
And the dome sheet 32. Since the partition part 37 is only sealed in a spot shape at two points, it is easy to separate and collect two sheets in the used blister pack.
