Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a strip pack for individually packing tablets and the like.

[0002]

2. Description of the Related Art Tablets are generally packaged individually.
Press-through packs and strip packs (Strip
Pack). In the former, the tablets are pushed out with a finger to break the package and the tablets are taken out, whereas in the latter, the individual packages are torn by hand or cut with scissors or the like to take out the tablets.

[0003]

By the way, in this type of packaging, since the tablet is taken out as easily as possible, especially a packaging material having good tearability is used, so that both infants and young children can easily open the tablet. It is possible. On the other hand, some tablets are inconvenient to be taken by infants, so-called Child Proof (Child Proof)
Of which a means for preventing opening called "of) has been applied.

[0004] However, if a material that is difficult to tear is used for the strip pack, even if it is not provided with scissors, it cannot be opened even by an adult, and the strip pack is inherently convenient, that is, it is easy to carry and can be used anytime and anywhere. That convenience is lost.

An object of the present invention is to provide a strip pack which can be easily opened even if a material having high tear strength is used.

[0006]

[MEANS FOR SOLVING PROBLEMS] To solve the above-mentioned problems, a first method is described.
In the invention of the present invention, both sides of the laminated body provided with the easily peelable adhesive layer on both sides of the base material are respectively folded on both front and back sides, and one row of tablets is stored in the folded part in correspondence with the other row, A vertical heat sealing band that is fixed in a flat bag shape while leaving the side edges of the folded portion on the front and back, and a horizontal heat sealing band that intersects the vertical heat sealing band and separates a corresponding pair of tablets from a pair of adjacent tablets. The configuration provided was adopted.

Further, in the second invention, both sides of a laminate having an easily peelable adhesive layer provided on both sides of a base material are folded on one surface side, and one row of tablets is corresponded to the other row in the folded portion. A vertical heat sealing band that secures the folded portion in a flat bag shape while leaving the side edges of the folded portion in a state where the side portions of the folded portion are respectively turned outward, and corresponds to the vertical heat sealing band. A horizontal heat sealing band for separating a pair of tablets to be separated from a pair of adjacent tablets is provided.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a laminate used for the strip pack of the present invention. As shown in the figure, the laminate 1 is provided with the easily peelable adhesive layers 11 and 12 on both surfaces of the base material 10. The substrate 10 is made of a single synthetic resin film such as polyethylene, polypropylene, or polyester, or a composite thereof, or a single metal foil such as an aluminum foil, or a composite of a metal foil and the synthetic resin film, or synthesized with paper. It is composed of a composite with a resin film. The easily peelable adhesive layers 11 and 12 are layers having an adhesive strength enough to be peelable by hand when heat-sealed to each other as described later, and may be formed of an adhesive having both easy peel properties. As shown in FIG. 2, one layer 11 is formed of a resin layer 11a having low adhesiveness such as a silicone resin, a Teflon (trade name) resin, or a polyamide resin and a normal thermoplastic adhesive layer 11b. The other layer 12 may be formed of an adhesive having an easy peel property. Further, as shown in FIG.
a, 12a and ordinary thermoplastic adhesives 11b, 12b. If the adhesiveness of the base material 10 itself is weak, the layers 11a and 12a can be omitted. As shown in FIGS. 4 and 5, the layers 11 and 12 do not need to be provided on the entire surface of the base material 10, but can be provided only where necessary by part coating.

The method of laminating the substrate 10 and the easily peelable adhesive layers 11 and 12 may be any of lamination, roll coating, extrusion coating and the like. And the laminate 1
It is preferable to increase the tearing strength so that infants and the like cannot easily tear.

A strip pack as shown in FIGS. 6 and 7 is formed by using the above-mentioned laminate 1. Next, an example of a method for forming the strip pack 20 will be described. First, while feeding the laminate 1 in the vertical direction, a portion closer to the side edge from the center of one surface of the laminate 1 is sequentially folded in the length direction to form a cylindrical tablet storage portion 13a. The portion near the side edge from the center is sequentially folded, and the cylindrical storage portion 13 is formed.
b is formed. At the same time that the storage portions 13a and 13b are formed, one tablet T is put into each of the storage portions 13a and 13b,
A vertical heat sealing band 21 is formed at the central portion where the layers overlap. Thereby, the cylindrical storage unit 1 storing the tablets T on both sides.
Since 3a and 13b are formed, the transverse heat sealing band 22 is sequentially formed every time the input of one tablet is completed. As a result, each tablet T is separated by the vertical and horizontal heat sealing bands 21 and 22 and is sealed in the flat bag-shaped storage portion. If a perforated perforation 23 is provided substantially at the center line of the lateral sealing band 22 of the strip pack 20, the package can be divided into a package containing a pair of tablets T by tearing along the perforated line 23. . To open the package, grasp the free side edge 24 with fingers and pull it up.
Since the vertical and horizontal heat sealing bands 21 and 22 are formed by the easily peelable adhesive layers 11 and 12, the tablets can be easily peeled off and the tablet T can be taken out. However, since both ends of the side edge portion 24 are fixed by the adjacent lateral heat sealing band 22 and are tightly adhered to the outer surface of the package, they are indistinguishable to children, difficult to pinch, and have a child-proof property. high. When it is difficult for the elderly to pinch the side edge portion 24, a tab 24a may be provided as shown in FIG.

As shown in FIG. 9 and FIG. 10, tablets T are arranged in two rows on both sides of the center of the laminate 1 and both sides of the laminate 1 are folded to cover the tablets T. A vertical heat sealing band 21 similar to the above is formed, and a horizontal heat sealing band 22 crossing the vertical heat sealing band 21 is formed. In the case of this strip pack 20 a, the dividing perforation 25 is provided at the center of the vertical heat sealing band 21.
(Not possible with the strip pack 20 of FIGS. 6 and 7). Therefore, it can be divided into a package containing a single tablet T. When opening, see FIG.
When the tab 24a is lifted up with a finger as shown by a dashed line, the lateral heat sealing strips 22 are peeled off and pulled in the opposite direction (right side in the figure) in a substantially vertical state as shown in FIG.
Is peeled off, and the tablet can be taken out.

[0012]

According to the present invention, as described above, tablets are stored in a flat bag shape by a laminate in which the easily peelable adhesive layer is provided on both surfaces of the base material, and the tablets are retained while leaving the side edges of the laminate. Since the vertical and horizontal heat sealing bands are provided so as to surround, the laminate itself can be formed of a material having a large tear strength to improve the child proof property, while the tablet is peeled off from the side edge that is not heat sealed to form a tablet. Can be easily taken out without any scissors or the like. In addition, since the side edge portion is in close contact with the outer surface of the strip pack, it can be easily pinched by a finger in an adult, but difficult in a young child, so that the child-proof property is further enhanced.
