Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application: The present invention relates to a package that tightly wraps a product in close contact with the product by loosely wrapping the product with a heat-shrinkable plastic film and then heating the film.

Conventional Structure and Problems Conventionally, shrink wrapping wraps tightly around the product, giving it a beautiful finish, making it possible to easily bundle irregularly shaped items, increasing the value of the product, and It is protected and used in a wide range of product fields.

FIG. 1 shows a conventional package.

In Fig. 1, numeral 1 indicates the packaged object, which is a two-layer heat-shrinkable plastic film, and shows the finished state after the packaged object 1 is sealed on three sides, heat is applied, and shrink-wrapped. be.

However, in the above-mentioned shrinkage method, as is clear from Fig. 1, the package has a high airtightness due to its tight packaging, but it has the drawback that it is difficult to open the package. By using a sharp object, aging 1
A cutout was forcibly formed in the a-type film 2, and the seal was opened using the cutout. This requires time and effort to open, making it impractical.

OBJECT OF THE INVENTION The present invention solves the above-mentioned drawbacks of the prior art.
The object of the present invention is to provide a package that can be easily opened using a small number of parts and a construction method.

Structure of the Invention In order to achieve this object, an invention was made in which a heat-shrinkable film is provided with a U-shaped cutout or a similar shape, and an adhesive label for opening is pasted on the cutout. It is something.

With this configuration, shrink wrapping is possible without sacrificing the strength of the heat shrink film, and even in tight shrink wrapping,
It can be opened without difficulty.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2, 3, and 4. Note that in FIG. 2, the same parts as in FIG. 1 are given the same numbers.

FIG. 2 shows an embodiment of the present invention, in which 1 is an object to be packaged, and 2 is a shrinkable material in which a cutout 2a having a U-shape or similar shape is provided by a method such as pressing. The heat-shrinkable film 3 before packaging is a label made of paper such as Kobo paper, which is made of an adhesive layer 5 and industrial paper 4a such as Kobo paper as shown in FIG. It is.

With the film composed of the heat-shrinkable film 2 and the label 3, the packaged object 1 is loosely wrapped, such as with a three-color sticker, and then shrink-wrapped by heating as shown in FIG. That will happen.

Next, as shown in FIG. 8, for example, the opening label 3 without the adhesive layer 5 attached to one end is shown in FIG.

By inserting the notch 2 of the heat shrink film 2 as shown in FIG.
Since force is applied to a, the package can be opened very easily without the need to use a sharp knife to make a cut for opening as in the past.

In addition, if the notch 2a for opening is simply opened, when the packaged item 1 is shrink-wrapped, if heat is applied directly to the notch, a hole will be formed starting from the notch, and the meaning of shrink-wrapping (appearance) will be However, by attaching the label 3 to the heat-shrinkable film 2 in this way, the notch 2a can be protected from direct heat from the outside and can also be used as an opening label. can also be used. 2 in Figure 6
b.

2C is a cutout "'" which is another embodiment of the present invention. Fig. 7 is an opening label which is another embodiment of the present invention, and shows the opening direction 1 quality assurance mark etc. Figures 8a and 8b show its cross section.

Effects of the Invention As described above, the present invention uses a heat-shrinkable film with cutouts and a tearable label, so that the film strength is not deteriorated and is no different from conventional shrink packaging. It can be wrapped, and even tight shrink packaging can be opened with one touch by using the opening label.
