Description

  The present invention relates to a blister pack.

Blister packs used for the distribution of merchandise, etc. (hereinafter referred to as “articles”) and at the time of sale cover a part of the front facing the article storage space and cover the front of the mount. It has a blister body made possible.
The blister body is made of synthetic resin and is often manufactured by vacuum forming or the like. In general, the base sheet and the blister main body are joined by binding using a stapler, sticking using an adhesive tape, heat fusion, ultrasonic welding, or adhesion using an adhesive or hot melt.

In order to position the mount and the blister body when they are joined together, the folded pieces parallel to each other are formed on the two sides of the blister body that are opposite to each other in the outer periphery of the blister body. In some cases, a method of inserting a mount between them like a guide rail is used (see, for example, Patent Document 1).
Japanese Utility Model Publication No. 7-9168

In blister packs, it is easy to give the mount and the blister body a certain level of strength, and it can serve as a good packaging material or storage container by decorating the mount or making the blister body transparent. It can also be made. In today's screaming trash reduction and resource saving, it was sometimes considered a problem to dispose of blister packs only for the distribution and sale of goods.
Therefore, it is conceivable to reuse the blister pack. However, in order to enable this reuse, it is necessary to have a structure in which the mount and the blister body can be freely attached and detached and the attachment and detachment can be repeated. Here, as employed in the conventional blister pack, it is useful to provide two blister pieces (guide rail-shaped) parallel to each other in the blister body and to insert the mount between them.

However, when adopting such an insertion structure, the mount is required to be square, and the blister body is also formed with a flange portion that is largely wasted around the article storage space. The front view must be square. Therefore, both the blister main body and the mount are costly wasted, and the outer shape is limited to a square, so that there is no design freedom.
It should be noted that the blister body needs to be provided with a folded piece in a region that occupies most of the outer peripheral portion or in the entire circumference, and laborious heat processing is required when the folded piece is provided. This has been a bottleneck in cost reduction.

  The present invention has been made in view of the above circumstances, and can be reused by eliminating costly waste as much as possible and by increasing design freedom. An object of the present invention is to provide a blister pack.

In order to achieve the above object, the present invention has taken the following measures.
That is, the blister pack according to the present invention has a mount used for backing up articles with a part of the front facing the article storage space, and a blister body that can cover the front of the mount. Is provided with a dome that covers the article storage space, and a flange that extends over the entire circumference of the dome to enable surface bonding with the mount. The flange has a free end toward the dome. A plurality of mounting claws formed by facing and raising are provided at predetermined intervals along the outer peripheral portion of the flange portion.

The plurality of holding claws provided on the flange portion of the blister body can hold the mount in a state of holding the mount with respect to the blister body, but are flexible enough to freely engage and disengage from the mount. Since it has elasticity, it becomes possible to repeatedly attach and detach the blister body and the mount. Thereby, reuse as a blister pack becomes possible.
Here, since the structure that enables the blister body and the mount to be attached and detached is realized by a plurality of holding claws provided on the flange portion of the blister body, it is not particularly important to make the mount square. For example, a circular shape, an oval shape, or an external shape that looks like a character can be used for the mount. Of course, also about the flange part of the blister body. Similar arbitrary shapes can be adopted according to the outer shape of the mount.

For this reason, it is not necessary for the blister body to overhang and form a flange part that is largely wasted around the article storage space, eliminating cost waste in both the blister body and the mount, and freedom in design. This leads to the advantage that the degree can be expanded.
Also, unlike the conventional blister body, the blister body does not need to be provided with a folded piece in the area that occupies most of the outer peripheral portion or in the entire circumference, so it takes time and labor required to provide such a folded piece. There is an advantage that thermal processing becomes unnecessary. This is also beneficial for cost reduction.

It is preferable to form a reinforcing rib on the flange portion of the blister body to prevent the relative backlash of the mount by fitting the outer periphery of the mount.
By doing so, it is possible to reinforce the flange portion, reinforce each holding claw, and reinforce the elastic force. In addition, since the relative positioning of the blister body and the mount is possible, a reliable engagement of the individual holding claws with the mount and a uniform engagement state by all the holding claws can be obtained. There is an advantage that the coupling state with the mount is ensured.
The mount allows engagement of only the toe of the holding claw with respect to the portion corresponding to the holding claw of the blister body in the outer peripheral portion, and the base of the holding claw in the engaged state of the flange portion. It is preferable to form a notch for exposure so that it can be pushed from the surface side.

  If such a notch is formed on the mount, the state where the base of the holding claw is exposed on the surface side of the flange portion of the blister body (exposed state) when the blister body and the mount are combined. Therefore, the root of this nail can be pushed directly with a fingertip or the like. Therefore, the operation of releasing the engagement from the state in which the holding claw is engaged with the notch of the mount can be easily performed.

  The blister pack according to the present invention substantially eliminates cost waste in both the blister body and the mount, and can increase the degree of design freedom. It can be reused.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 6 show an embodiment of a blister pack 1 according to the present invention. The blister pack 1 has a mount 2 and a blister body 3, and the blister body 3 can cover the entire front surface 2 a of the mount 2 (or only a part in some cases).
The mount 2 is formed of white cardboard, cardboard, resin-impregnated paper, resin-coated paper, resin wrapping paper, or other paper, a resin sheet, etc., and a part of the front surface 2a is an article storage space (article backup) It is used so as to face the space.

The blister body 3 is appropriately formed of a synthetic resin material, and has a dome portion 6 and a flange portion 7 that projects over the entire circumference of the dome portion 6 and enables surface bonding with the mount 2. Yes. Examples of the synthetic resin that can be used include polyvinyl chloride, polyethylene, polypropylene, polyethylene terephthalate, polystyrene, polycarbonate, and polyacrylonitrile. In addition, it is preferably transparent or colored transparent.
The dome portion 6 has a shape bulging with a hollow inside, and covers an article accommodation space (not shown) accommodated in the article accommodation space together with an article accommodation space formed on the front surface 2a of the mount 2. It has become. The shape of the bulge may be appropriately changed according to the size and shape of the article to be accommodated.

The flange portion 7 is provided in a state in which the outer peripheral portion of the dome portion 6 is bent outward, and is provided in a frame shape so as to surround the outer peripheral portion of the dome portion 6 all around. It has been. The flange portion 7 can be formed so as to keep the predetermined width substantially constant at the outer peripheral portion of the dome portion 6, and may be formed with an appropriate width dimension regardless of the outer peripheral portion of the dome portion 6. You can also.
By the way, as for the outer shape of the mount 2 and the outer shape of the entire flange portion 7 of the blister body 3 (the overall outline when the blister pack 1 is viewed from the front), the dome portion when the blister body 3 is viewed in plan. If it is larger than 6 sizes, it will not specifically limit. That is, it is not limited that both are square (there are two straight sides parallel to each other in the outer peripheral portion).

In the present embodiment, the outer shape of the mount 2 is an ellipse, and the outer shape of the entire flange portion 7 in the blister body 3 is also an ellipse that is slightly larger than the mount 2.
In the blister body 3, a plurality of holding claws 10 for the mount 2 are provided on the flange portion 7 at predetermined intervals along the outer peripheral portion of the flange portion 7. Further, the reinforcing rib 11 is formed so as to border the outer peripheral portion of the flange portion 7 on the outside of each of the holding claws 10.
By forming the reinforcing rib 11 on the flange portion 7, the entire reinforcing rib 11, and thus the blister body 3 as a whole, has increased rigidity and is difficult to be deformed. Further, the reinforcing rib 11 causes a step that is recessed by one step on the back surface of the flange portion 7, and the outer peripheral portion of the mount 2 can be fitted into this step. The size, the amount of step, and the shape of the reinforcing rib 11 are set so that the mount 2 does not rattle within the step.

Each of the holding claws 10 is formed by a cut-and-raised portion provided on the flange portion 7, and the free ends generated by the cut-and-raise are all directed toward the dome portion 6 (the bent portions generated by the cut-and-raise are provided with reinforcing ribs). 11). As is clear from this, since the holding part of the holding claw 10 produced by cutting and raising is close to the reinforcing rib 11, the rigidity of the holding claw 10 itself is enhanced by the reinforcing rib 11, and the elastic force is also increased. It will be strengthened.
The arrangement and number of the holding claws 10 are not particularly limited. However, it is preferable to arrange them so that they face each other across the dome 6 (it is not always necessary to match the opposing positions, and a staggered arrangement may be used).

In the illustrated example, the holding claws 10 are provided in five places in total. The breakdown is that two oval claws 10 are provided for the elliptical curve having two sides in the elliptical flange portion 7 so as to face each other between the two elliptical curves (via the dome portion 6). It is. In addition, a holding claw 10 is provided at one position with respect to one of the short circular curves having two sides in the flange portion 7. A round hole 14 for hooking is provided on the other side of the short circle curve so as to penetrate the flange portion 7 of the blister body 3 and the mount 2.
On the other hand, the mount 2 is provided with notches 15 at a plurality of locations on the outer peripheral portion so as to correspond to the holding claws 10 of the blister body 3. This notch 15 enables engagement with only the toe of the holding claw 10. When the toe of the holding claw 10 and the notch 15 are in the engaged state, the base of the holding claw 10 is exposed so as to be pressed from the surface side of the flange portion 7 (see FIG. 6).

In this embodiment, as shown in FIG. 4, the dimension L from the toe of the holding claw 10 to the root is about 5 mm, and the dimension M closer to the toe that engages with the notch 15 is about 2.5 mm. The dimension N closer to the root that is exposed to the surface side of 7 was about 2.5 mm. The notch amount R of the notch 15 was about 3 mm.
In the blister pack 1 according to the present invention, from the state where the blister body 3 and the mount 2 are coupled as shown in FIG. 4, in order to separate them as shown in FIG. 5, first, as shown in FIG. A fingertip is inserted from the surface side of the flange portion 7 in the blister body 3 toward a portion where the root of each holding claw 10 is exposed (a portion of the dimension N exposed by the notch 15 of the mount 2). The root is pushed together with the mount 2.

Thereby, the holding claw 10 can be released from the state of being engaged with the notch 15 of the mount 2. In this way, the blister body 3 and the mount 2 can be detached by releasing the engagement between the predetermined number or all of the holding claws 10 and the notches 15 of the mount 2.
On the other hand, in order to connect the blister body 3 and the mount 2 as shown in FIG. 4 from the state where the blister body 3 and the mount 2 are separated, first, an elliptic curve on one side of the flange portion 7 of the blister body 3 is first formed. The notches 15 of the mount 2 are inserted into the holding claws 10 arranged side by side, and are engaged with each other.
At this time, since the reinforcing rib 11 is provided on the flange portion 7 of the blister body 3, the relative positioning between the blister body 3 and the mount 2 can be easily performed.

And about the holding claw 10 arranged in the ellipse curve of the opposite side in the flange part 7 of the blister main body 3, as shown in FIG. 6, the part to which the root of each holding claw 10 was exposed from the surface side of the flange part 7. The fingertip is inserted into (the portion of the dimension N exposed by the notch 15 of the mount 2), and the root of the holding claw 10 is pushed.
As a result, the holding claw 10 is temporarily brought over the notch 15 of the mount 2. Then, if the pushing by the fingertip is stopped, the holding claw 10 is engaged with the notch 15 by the elastic return action. In this way, the blister body 3 and the mount 2 can be coupled by engaging all of the remaining holding claws 10 and the notches 15 of the mount 2.

As described above in detail, in the blister pack 1 according to the present invention, the plurality of holding claws 10 provided on the flange portion 7 of the blister body 3 hold the mount 2 in the blister body 3. Can be retained. The holding claw 10 is flexible and elastic enough to freely engage and disengage from the mount 2, so that the blister body 3 and the mount 2 are repeatedly attached and detached repeatedly. You can do it.
Moreover, since the structure which enables attachment / detachment of the blister body 3 and the mount 2 is realized by a plurality of holding claws 10 provided on the flange portion 7 of the blister body 3, it is particularly important to make the mount 2 square. For example, the mount 2 may have a circular shape, an oval shape, or an outer shape that looks like a character. Of course, the same arbitrary shape can be adopted for the flange portion 7 of the blister body 3 in accordance with the shape of the mount 2.

For this reason, the blister pack 1 according to the present invention can be reused, and the flange portion 7 and the mount 2 of the blister body 3 do not need to be enlarged unnecessarily. The advantage is that the degree of freedom of design can be expanded.
By the way, this invention is not limited to the said embodiment, It can change suitably according to embodiment.

It is the perspective view which showed one Embodiment of the blister pack which concerns on this invention. It is the perspective view which showed a mode that it fractured | ruptured in the site | part corresponding to the AA line of FIG. FIG. 2 is an exploded perspective view in which the blister pack of FIG. 1 is separated into a blister body 3 and a mount 2. It is a BB line expanded sectional view of Drawing 1.
