Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a novel shrink package, and more particularly, to a package formed by shrink-packing a plurality of articles to be packaged such as cans, glass bottles, plastic bottles, paper packs, etc. The present invention relates to a novel shrink wrapping body in which the remaining wrappings are packed together.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, cans, glass bottles, plastic bottles, and paper packs are mainly used for containers of soft drinks, juices, beers, and the like, and cardboard boxes are used for packing and transporting these beverage containers. Cardboard boxes are especially used in large quantities because they are automatically assembled when packing beverage containers on the beverage company's automatic packaging line and can be unfolded or folded after the beverage containers are removed. Suitable for route sales. For packaging and transporting the beverage container, a shrink packaging method is employed in which the beverage container is stored in a tray-type container and then wrapped with a shrink film.
[0003]
[Problems to be solved by the invention]
However, since the cardboard boxes are disposable and cannot be used repeatedly, there is a problem in terms of resource saving, and since all are pasted, it takes time to open and fold them after use. Further, the cardboard box has a problem that it is difficult to take out the beverage container and the working efficiency is poor.
[0004]
Also, in the case of a cardboard box, when opened, the inside beverage container becomes fragmented and becomes difficult to handle. Therefore, in recent years, for example, six cans are packed in one pack and stored in a cardboard box. However, storing these packaged products in a cardboard box is a so-called double packing, and the consumption of resources is further increased. Will be. Further, there is a problem that the cardboard box has poor water resistance.
[0005]
On the other hand, in the case of a shrink package using a tray-type container, there is no way to open the shrink film because there is no opening anywhere, and the only way is to tear open the shrink film. Further, at the time of opening, the tearing direction was not constant because the tear was opened so as to tear from a part, and the size of the opening was not constant. For this reason, there was a problem that after opening the cans, the cans fell apart and were difficult to handle. Therefore, in the shrink package, the tray can be collected and reused, but there is a problem of difficulty in opening and difficulty in handling the remaining packaged material after opening.
[0006]
The present invention has been made in view of the above situation, and it is an object of the present invention to provide a shrink wrapping body that can easily and optionally be opened at a shrink wrapping body. Further, the present invention provides a shrink package that can be stored and transported as a single unit, even if an arbitrary package is taken out after opening and the remaining package does not fall apart.
[0007]
[Means for Solving the Problems]
The present invention has the following configuration to achieve the above object. That is, a shrink wrapper according to the present invention is characterized in that, in a shrink wrapper obtained by integrally shrink wrapping a plurality of objects to be wrapped, perforations are provided in the shrink film. It is preferable that the perforations are provided along a row of the articles to be packaged. Further, the shrink package may be a package in which a plurality of packages are stored in a tray, or may be a package in which a plurality of packages are simply placed on a plate. Good. Further, specifically, a shrink wrapping body in which the to-be-packaged material is a beverage container, which is stored in a tray, and perforations are provided along the container row, can be provided. The perforations may be provided in all of the container rows, or may be provided in some of the container rows or partially omitted.
[0008]
Only the portion to be taken out can be opened by tearing along the perforations, and the shrink-packed state is maintained for the portions other than the taken-out portion, so that they do not fall apart.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a perspective view of a shrink package according to the present invention. In the shrink package 1, reference numeral 2 denotes a beverage can as an article to be packaged, reference numeral 3 denotes a tray for storing the beverage can 2, and reference numeral 4 denotes heat-shrinkable packaging of the beverage can 2 and the tray 3. It is a shrink film made of synthetic resin.
[0010]
The tray 3 has a planar rectangular shape, and a bottom plate 3b is provided at a height position substantially in the middle of the side wall 3a, and a step 3c is formed on the outer surface of the side wall 3a at a height position of the bottom plate 3b. Have been. The side wall 3a is formed such that a portion below the step portion 3c extends outward beyond a portion above the step portion 3c. Therefore, the trays 3 can be stacked one on another by fitting the lower part of the side wall of the upper tray to the upper part of the side wall of the lower tray 3.
[0011]
A lattice-shaped or cross-shaped reinforcing rib 3d is provided along the side wall on the lower surface of the bottom plate 3b to prevent the bottom plate 3b from being loosened by the load of the stored can. In place of the reinforcing rib 3d, a column having the same height as the lower surface of the side wall 3a may be protruded downward at the center of the lower surface of the bottom plate 3b.
[0012]
The shrink film 4 formed by packaging the can is provided with perforations 5 in the vertical and horizontal directions. The perforations 5 are preferably provided vertically and horizontally so as to be located between the can rows. Further, the perforations 5 need not be provided between all the can rows, and can be omitted as appropriate. For example, in the illustrated embodiment, the central portion may be omitted in the longitudinal direction and provided only on the side wall side.
[0013]
In the above configuration, in order to perform shrink packaging with the shrink film 4, the perforations 5 may be provided in advance in the shrink film 4 itself. The shrink wrapping with the shrink film 4 provided with the perforations 5 may be performed in the same manner as in the related art. The beverage can 2 wrapped in the tray 3 is wrapped, and this is heated by a shrink wrapping machine (not shown). What is necessary is just to shrink.
[0014]
Next, in order to open the shrink wrapper 1, the appropriate position of the perforation 5 may be pressed to break it, and the tear may be torn along the perforation. If one part is broken and torn, it can be opened by tearing any length and length along the perforation. The size of the opening to be opened may be appropriately determined according to the number of cans to be taken out.
[0015]
4 and 5 are perspective views showing an example of opening. As shown in FIG. 4, the perforation 5 at the edge in the short direction may be pressed to break, and the tear may be torn along the perforation. Even if the beverage cans 2 in the end row are taken out, as shown in FIG. 5, the remaining beverage cans are still in the state of the shrink wrapping, so that the beverage cans do not shift or break apart. .
[0016]
In the above-described embodiment, the case where 24 4 × 6 beverage cans are stored in the tray is described. However, the present invention is not limited to this case. Of course, it can also be carried out. Further, the tray is not limited to the structure in the above embodiment, and may be a simple plate-like body as long as it can store or place an article to be packaged. If it is made of paper and made of wood, its material does not matter.
[0017]
【The invention's effect】
As is apparent from the above description, since the perforations are provided in the shrink film, the present invention can be easily and quickly opened by hand by pressing the perforations. Further, since the opening can be opened to an arbitrary size along the perforation, the size of the opening can be changed each time according to the number of pieces to be taken out. In addition, the remaining beverage container portion can be stored and transported as a shrink wrapped body without falling apart since the state of the shrink wrap is maintained as it is.
