Abstract

PROBLEM TO BE SOLVED: To provide a package having the resealable function, which has protective and easily unsealable properties as seen in a soft carton, etc., and which is so designed as to be resealed simply. SOLUTION: A back surface sheet 15 provided with a lid sheet 13 and an insertion piece (p) and side sheets 12 provided with flaps (f) via folding portions (g) on both sides of the back surface sheet 15 are partially stuck on the central portion on an inner face side of a resin film 11 having a transparent or a metal deposit thereon. By folding the resin film 11 inwardly and bonding or welding right and left end margins (t) and a lower end margin (h) in the vicinity of the central portion, a cylindrical packaging bag including a frame body comprising the back surface sheet and the side face sheets is formed. After contents are inserted into the frame body, a lid of the frame body is closed and, by bonding or welding an upper end margin (h), a sealed package having the resealable function is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can store solids such as caramel, gum, consommé soup, solid soap, nutritional supplements, etc., and prevent the contents from popping out even after the packaging bag is opened. The present invention relates to a package having a resealing function.

[0002]

2. Description of the Related Art Conventionally, as a container for candy, gum, etc., as shown in FIG. 4, for example, a small box or a packaging material comprising an aluminum vapor-deposited layer or an aluminum foil-bonded film and a paper base is used. Most of them did.

[0003] However, in the case of the above-mentioned small box, although it has a reseal function, even if the contents of the candy etc. decrease, the shape cannot be reduced as a container, and the small box is kept until all the candy etc. disappear. Needed to be retained. Also, when using the latter packaging material consisting of a paper base material and a vapor-deposited film, etc., the protective property is low, it is possible to reseal it in a small size, but it becomes unattractive and when taking it out again, Further, there is a problem that it is necessary to break the packaging material.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a protective and easy-opening property found in conventional containers and the like. Another object of the present invention is to provide a package having a resealing function that can be easily resealed.

[0005]

In order to achieve the above object, the present invention relates to a back plate having a cover plate 13 and an insertion piece p provided at a central portion on the inner surface side of a resin film 11 having a transparent or metal-deposited layer. 15 and the side plates 12, 12 provided with flaps f, f on both sides thereof via folding parts g, g, and the resin film 11 is bent inward, and left and right end pieces near the center. A cylindrical packaging bag in which a frame by a back plate and a side plate formed by adhering or fusing t, t and a lower end h is included, wherein the contents are inserted into the frame, and the frame is inserted. This is a package having a reseal function, in which the lid of the body is closed and the upper end h is adhered or fused and sealed.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION A package according to the present invention comprises a back plate 15 having a lid and a side plate 12 on the inner surface side of a resin film 11 provided with a transparent or metal deposition layer of aluminum, alumina, silicon oxide or the like. 12 is partially adhered, the resin film 11 is bent inward, and left and right end pieces t, t near the center.
And a lower end portion h are bonded or fused to form a cylindrical packaging bag in which a frame for storing the contents is enclosed, and the contents such as solids are inserted into the frame, and the frame is inserted into the frame. A package having a reseal function, which is sealed by the provided lid portion and sealed by bonding or fusing the upper end h of the packaging bag, is obtained. That is, by tearing the upper part of the packaging bag and taking out the contents, by closing the lid of the enclosed frame, the packaging bag can be resealed even if the packaging bag is broken, and the contents can be protected. Body.

Further, the embodiment will be described in detail with reference to the drawings. FIG. 1 is a developed view of a package having a reseal function of the present invention, and FIG. 2 is a perspective view of the assembled package. As shown in FIG. 1, at the center on the inner surface side of a resin film 11 provided with a transparent or aluminum, alumina, silicon oxide or the like metal deposition layer, a back plate 15 provided with a lid plate 13 and an insertion piece p, This is a sheet-like packaging material in which side plates 12, 12 provided with flaps f, f on both sides thereof are partially adhered (shaded portions in the drawing).

As the resin film 11, for example,
Considering the printability, lateral tearing properties and barrier properties of the surface, polyethylene terephthalate (PET) 12 μm from the surface side
/ Horizontal uniaxially stretched high-density polyethylene (HDPE) 18 μm
(For example, Karariyan Y18 μm, manufactured by Toyo Chemical Co., Ltd.) / Metal-deposited unstretched polypropylene (VMCPP) 2
5 μm configuration or PET 12 μm / VMCP
A packaging material film having a P of 25 μm was used.

Further, the back plate 15 and the side plate 12 contained in the packaging bag may be made of PET (12 μm) from the front side in consideration of printability, appropriate rigidity, ruled line suitability and adhesiveness, for example, as described above.
m) / paper (190 g / m ² ) / PE (15 μm) / CP
P (25 μm), punched out according to the size of the packaging bag.

Next, the resin film 11 to which the mount is adhered is bent from the folded portions g, g, g, g, and the right and left end pieces f, f are bonded or fused in the vicinity of the central portion.
The lower film 2 and the lower film 12 are folded inward in accordance with the folded portions e and e, and the lower end portions h and h are bonded or fused to form a cylindrical package including a frame by the back plate 15 and the side plate 12. Form a bag.

Further, solids (eg, caramel, consommé soup, etc.) are inserted in parallel into the frame, and the flaps f, f
By closing the lid by f and the lid plate 13 and bonding or fusing the upper end h while folding the folded portions e, e of the film above the side plate, the package 10 as shown in FIG. Is obtained.

As shown in FIG. 3 (A), this package 10 can be suspended and displayed for sale by providing a through hole or the like at the upper end portion h, and several packages can be put together. It is also possible to put them in other packaging boxes and sell them.

Further, as shown in FIG. 3 (B), the package body is torn laterally over the bag to take out a required number of solid contents, and then the lid of the frame is closed to close the contents. Does not fall outside. Therefore, the remaining contents can be easily protected, and the contents can be easily taken out again, without having to close the packaging bag with an adhesive tape or the like. Further, since the upper part of the bag is torn, the frame is attached to the bag, so that the remaining contents can be easily stored.

[0014]

As described above, the present invention has the following effects. That is, the package has good shape retention properties by the frame and can protect the contents. In addition, since it has a reseal function, it is easy to take out the contents and open it when reusing. Further, it can be manufactured by the same manufacturing process as the conventional package, and the packaging material and the manufacturing cost can be reduced.
