Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an integrated packaging body and an integrated packaging method for products that can be carried by hand.

Conventionally, for the purpose of accumulating and storing or transporting multiple products, such as products in paper boxes, multiple products have been stacked together and packaged by hanging them with strings or storing them in plastic bags. ing. However, with these methods, no consideration was given to the sealability of the contents or the advertising effectiveness, and the packaging of the product was inadequate.In addition, portability was not necessarily satisfied. Therefore, the object of the present invention is to provide a portable collection that is stable and easy to carry, has excellent packaging tightness and sealing properties, has high advertising effectiveness, and can be easily obtained. The objective is to provide a package.

That is, in the first invention of the present application, a stretchable string-like body is wound around the four circumferences of a content accumulation in which a plurality of contents are piled up, and at least one of the string-like bodies is wrapped from above the string-like body. A special feature of the present invention is that the above-mentioned assembly is shrink-wrapped with a heat-shrinkable film, leaving an uncovered part exposed so that the exposed part of the string-like body can be used as a handle.

In addition, the second invention of the present application is to bind a plurality of items to be packaged one on top of the other with an elastic string-like body, and then wrap a heat-shrinkable film thereon, Subsequently, a heat shrinking treatment is applied to cover the packaged item closely with the film while leaving an uncovered portion where the string-like body is exposed.

Next, the present invention will be explained using specific examples shown in the drawings.

FIGS. 1 and 2 show an example of integrated packaging that can be provided according to the present invention, that is, an example of integrated packaging of a plurality of υ products in paper boxes. A plurality of boxed products A (five in the drawing) are stacked one on top of the other, and a stretchable string-like body 1 is wrapped around the product A to bind the entire stack of products A. There is. The material used for the string-like body 1 is preferably a uniaxially stretched shrink polyethylene film having a thickness of, for example, 60 μm. The entire assembly A of the product a'' is further covered with a heat-shrinkable fat film 2 in close contact with the string-like body 1, forming a cover for the product.This cover includes the following: An uncoated portion 3 is formed to expose at least a portion of the string-like body 1. As the heat-shrinkable film 2, for example, a uniaxially stretched shrink film of polyethylene, polypropylene, vinyl chloride, etc. is used. In this example, a 27μ thick uniaxially stretched shrink polyethylene film is used.

Considering the effectiveness of advertising during packaging, it is preferable that the film 2 is a transparent film. Heat shrinkable film 2
The uncoated portion 3 is provided at the center of the top and/or bottom surface of the product collection, and at the center of the side surface through which the twisted or string-like body l passes.

The string-like body l exposed from the uncovered part 3 of the heat-shrinkable film 2 is made of a stretchable material, so when carrying the product collection, it can be pulled out from the uncovered part 3 and carried. It can be used as hand 4 (Figure 2).

As described above, in the portable stacked packaging of the present invention, the product stack is first bound with the elastic string-like body 1, and then the heat-shrinkable film 2 is closely covered, so that the product Not only is the accumulated state maintained stably during storage or transportation, but also the tightness and airtightness of the package are ensured.

By leaving a part of the heat-shrinkable film 2 uncovered and exposing the string-like body 1, the string-like body 1 not only functions as a hoop (comb) for collecting products, but also as a handle. It can also be used as Furthermore, since the heat-shrinkable film 2 is tightly coated on the product, especially when a transparent covering film is used, the product display can be seen through and appear on the outside, increasing advertising effectiveness. 0 Next, the integrated packaging method of the present invention will be explained.

First, as shown in Fig. 3, a predetermined number of products A that are continuously conveyed in the direction of the arrow are bound with an elastic string-like body 1. To explain more specifically, for example, a long elastic string-like body 1.1 is let out from a roll 11.11, attached along the conveyance direction of the products A, that is, the stacking direction, and tied around the stack. The string-like bodies 1, 1 on both sides are joined at the front and back of each stack so that the body becomes ring-shaped, and then cut. When using a uniaxially stretched thermoplastic resin film as the stretchable string-like body, a long string-like body 1.
1 to each stack from both sides, and the preceding stack A
A heat sealer 12 is used to thermally weld the discontinued aggregates A, and a heat cutter 13 is used to cut them.

Next, each aggregate A is introduced into a shrinkage tunnel, and the uniaxially stretched film is shrunk in the transport direction so as to be brought into close contact with the aggregate A.

Next, the string-like body-attached assembly A' obtained as described above is conveyed in the direction of the arrow shown in FIG.
．． 21 and continuously attached to both sides of each stack A'. The attached heat-shrinkable films 2, 2 are thermally welded between each aggregate A'', A' by a heat solar 22, and then cut by a heat cutter 23, in the same way as when attaching the string-like body 1. When cutting with the heat cutter 23, it is preferable to provide a means for cooling the heat welded portion in the previous step.

In the example shown in FIG. 4, means 24 for cooling the heat-welded portion are provided on both sides of the heat cutter 23. Each aggregate A' after being cut by the heat cutter 23 is covered with a generally cylindrical heat-shrinkable film 2, and when it subsequently passes through a shrink tunnel and undergoes a heat-shrinking treatment, its four peripheries are heated. It will be tightly covered with a shrinkable film 2.

In addition, at this time, the upper surface and/or lower surface of the aggregate A',
Alternatively, in order to leave an uncoated portion on the side surface and form an exposed part of the string-like body 1, the stack A' is arranged so that the string-like body 1 is located in the opening 2a of the cylindrical body of the heat-shrinkable film 2. The IJ of the heat-shrinkable film 2 is selected to be wider than the width of the aggregate A' and to leave an uncoated portion.

As mentioned above, the method of the present invention basically consists of the step of winding a string-like body and the wrapping process of a heat-shrinkable film. Since the stacked state is stabilized by binding and then covered with a heat-shrinkable film, the integrated packaging of multiple contents can be carried out very easily and efficiently.
