JPH10129672A - Stretching-type paper pack - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a stretching-type paper pack with simple and efficient disposal to eliminate such inconvenience that most of paper packs have been disposed by appropriately folding, tying or cutting the packs for stacking flatly, requiring long processing time and a large space. SOLUTION: Intermediate folds 7 and outer folds 8 are provided on required portions of a paper board with heat-bonding synthetic resin layers 10 provided on both faces to provide a cube, while a cap 2 equipped with a vent hole 3 is attached to a surface of an upper lid 1. At the time of disposal, the cap 2 is loosened and a push-in point 5 indicated on a body is pushed toward the center while adjusting an intake-and-exhaust of air, the pack is formed like a contracted accordion, thereby providing the compact pack.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an extendable paper pack which has a function of expanding and contracting a currently used paper pack and which can be subjected to compression processing by using a cap provided with an air hole.

[0002]

2. Description of the Related Art Heretofore, in the disposal of waste paper packs, some of them have been folded vertically, but those of a retractable type have not been used.

[0003]

The conventional one is inconvenient to recycle because most of it is processed by various methods such as appropriately bending and tying, or cutting and opening the pack and stacking it in a plane. However, it took a long time and required a large space.

[0004]

SUMMARY OF THE INVENTION The present invention provides a milk or liquor paper pack which is currently in use, which has a telescopic function, is provided with a cap capable of adjusting the amount of air, and is compressed from above or from the side after use. If the accordion is shrunk, the finish will be compact, the space required for the disposal site will be small, and environmental conservation and recycling will be significant.
Easy handling saves labor and time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS At a required portion of a paperboard provided with a heat-adhesive synthetic resin layer on both sides, a folding line to be folded during compression and a point to be pressed are indicated.

When the present invention is made, a cubic is formed by providing an outer folding line which is folded outside, a pedestal is mounted on a plane of a top cover having a required inclination, a cap provided with an air hole at a required location is mounted, and a bottom cover is provided. To form a one-stage paper pack.

When the present invention constructed as described above is to be disposed of as a waste product, the cap is loosened so that the air hole provided in the cap and the inner cylinder is made common, and each of the pressing points is compressed toward the center. As the air is pushed out and the pack deforms as if it shrinks the accordion, push it in with both hands to assist it, finally close the cap and stop the movement of the air, a beautifully compressed paper pack Is completed.

According to a second aspect of the present invention, a two-stage paper pack is provided by adding a second stage under the one-stage paper pack to increase the amount, and providing a double line which also serves as a reinforcement at a center trunk portion. The method and function are the same as those of 0007.

[0009]

Embodiments will be described with reference to the drawings.
FIG. 1 is a perspective view of a one-stage paper pack A described in claim 1 of the present invention, which is folded into a required part of a paperboard provided with a heat-adhesive synthetic resin layer 10 on both sides when compressed. The folding line 7 and the indentation point 5 are displayed.

Further, an outer fold line 8 which is folded out is provided to form a cube, and a pedestal 4 is provided with a required inclination on the plane of the outer fold line 8 serving as the upper lid 1.
The cap 2 provided with is attached.

When the bottom cover 6 and other joints 9 are bonded to form a one-stage paper pack A, and the waste is disposed of, when the cap 2 is opened and closed to regulate air inflow and outflow, the push-in indicated on the pack is performed. When the point 5 is pushed into the center, the accordion is formed in a reduced shape, and a one-stage compressed paper pack B is obtained.

FIG. 2 is an enlarged perspective view showing the structure of the cap 2 provided on the pedestal 4 of the upper lid 1 in the embodiment shown in FIG. 2. An air hole 3 is used for adjusting the inflow and outflow of air when compressing the pack. To use.

In the embodiment shown in FIG. 3, II of FIG.
FIG. 4 is an enlarged cross-sectional view, in which an air hole 3 has a structure common to an inner cylinder air hole 11 by loosening a cap 2, and an upper lid 1 is inserted into a pedestal 4.

FIG. 4 is an exploded view of the one-stage paper pack A in the embodiment shown in FIG. 4. At the time of preparation, the cap 2 is provided on the surface of the upper lid 1 and the outer folding line 8 shown by a solid line is folded outward. Finally, the bottom cover 6 and other joints 9 are adhered. During compression, the cap 2 is loosened to adjust the inflow and outflow of the air, and the pressing point 5 is pushed toward the center. Is bent toward the center, and the accordion is compressed, but finally the cap 2 is closed to maintain the compressed state.

In the embodiment shown in FIG. 5, a cross section of the material of the present invention is shown, and a heat-adhesive synthetic resin layer 10 is provided on both sides of a paper 12.

FIG. 6 is a perspective view of a two-stage paper pack C and a two-stage compressed paper pack D in the embodiment shown in FIG. A two-stage paper pack C is provided by providing a double-lined outer line 13 which also serves to reinforce the body part, and is compressed to form a two-stage compressed paper pack D.
It is what it was.

FIG. 7 is an exploded view of the two-stage paper pack C in the embodiment shown in FIG. 7, in which the outer peripheral line 13 also serves to reinforce the central trunk portion. It is the same as the description.

[0018]

The present invention is embodied in the form described above and has the following effects.

When the present invention is to be disposed of, the cap is loosened, the cap and the inner cylinder are provided with a common air hole, and compressed while adjusting the inflow and outflow of the air to reduce the accordion. When the cap is closed, the compressed state is maintained and the compressed paper pack is completed neatly.

Further, since the handling is simple, the working time is shortened and the finish is compact, so that the working efficiency for recycling is improved.

Since it is no longer necessary to bend and tie or disassemble and open as in the prior art, the work area is minimized and the surrounding environment is improved.

If the brand, characteristics, etc. of the product are specified using the surface of the pack, a great effect can be obtained for advertising.

When about half of the liquid whose freshness is important is contained in the inside of the present invention, the cap is loosened to compress the pack and the air inside is pushed out as in the case of waste disposal. If the cap is closed when the vacuum is reached, the compressed state is maintained, which is effective for maintaining the freshness of the contents.
