JPH0692331A - Packaging method for cushions - Google Patents

Abstract

PURPOSE:To offer a packaging method by which a cushion can be packaged compact and in a state where it has a hardness of a certain degree, and kept from expanding up to the original size even when the airtightness is broken. CONSTITUTION:A cushion 1 is put into an external bag 2, vacuum-packaged and sealed so that it is flattened. The flattened cushion 1A is folded into three, put into an interior bag 4, vacuum-packed and sealed. When air inside the bag is sucked out for vacuum packaging, the cushion 1 is pressed by a press 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging method such as a cushion or a futon which is inflated with a large amount of air therein and is vacuum-packaged into a small state.

[0002]

2. Description of the Related Art Items such as cushions and futons that are inflated with a large amount of air inside are very bulky because they are inflated in a natural state. Therefore, the volume is reduced by vacuum packaging. That is, the cushions are vacuum-packed in a first airtight bag to be in a flat state, and stored, transferred, and displayed.

[0003]

However, in the conventional vacuum packaging, the inflated cushions are certainly flattened and the volume is reduced, but since it is in a fluffy state, it is difficult to handle. Further, when it is required to make the size smaller, there is a problem that even if it is folded, it is difficult to fold, and if it is forcibly folded, the bag is easily damaged.

Further, if the bag has pinholes or the like and the airtightness is broken, there is a problem that the bag inflates again. If the bags are doubled or tripled to solve such a problem, the risk of the airtightness being reduced will be reduced, but if the external protrusions etc. hit the airtightness, the airtightness will be easily torn and the original size will be restored. The problem of bulging is not solved.

Therefore, according to the present invention, the cushions can be packaged in a small size and have a certain degree of hardness, and even if the airtightness is broken, the cushion does not expand to the original size. It is intended to provide a way.

[0006]

In order to solve the above problems, the cushions are vacuum-packaged in a first airtight bag into a flat state, and the flat cushions are folded at least two times. , A second airtight bag, which is slightly larger than the folded cushions, is vacuum-packed and flatly packed.

[0007]

According to the above method, the cushions are vacuum-packed in the first airtight bag to be flat and the flat cushions are folded at least in two, so that the area is further reduced and Since it is folded in at least two and then put in a second airtight bag and further vacuum-packed, it becomes a plate having a certain degree of hardness.

Even if the airtightness is broken, the airtightness cannot inflate beyond the second outer airtight bag. Therefore, if the second airtight bag is made smaller than the first airtight bag, the expansion when the airtightness is broken can be suppressed.

EXAMPLES The cushioning method of the present invention will be described in detail below with reference to examples. 1 is a perspective view for explaining the steps of the cushion packaging method of the embodiment, FIG. 2 is a cross-sectional view of the steps, and FIG. 3 is a perspective view for explaining the cushion packaging method steps of the embodiment. 4 is a cross-sectional view of the above process.

In FIGS. 1 and 2, 1 is a cushion, 2 is an inner bag, and 3 is a press. First, the cushion 1 is put in the inner bag 2 and compressed by the press 3, and then the air in the bag is sucked to perform vacuum packaging. At this time, the inner bag 2
Is larger than the cross-sectional area of the cushion 1.

Through the above steps, the cushion 1 is in a flatly compressed state. In this state, the portion indicated by the broken line is fused and sealed. Next, the flatly compressed cushion 1 is put into the outer bag 4 as a three-folded cushion as shown by 1A in FIG. The width of the outer bag 4 is slightly wider than that of the three-folded cushion 1A.

As shown in FIG. 4, the outer bag 4 is compressed by a press 3 and then the air in the outer bag 4 is sucked to fuse the portion indicated by the broken line. Vacuum packaging by sealing. In the above, the inner bag 2 corresponds to the first airtight bag, and the outer bag 4 corresponds to the second airtight bag.

When the cushion 1 is vacuum-packed by the above steps, the volume of the cushion 1 becomes extremely small by vacuum packaging, and the width becomes small by folding it in three, so that the space efficiency of transportation, storage, exhibition, etc. is very good. The effect of becoming Furthermore, by folding it in three, it becomes a rigid plate shape, so that it is possible to obtain an effect that the handling becomes easy.

When the air inside the bag is sucked, it is pushed by a press to discharge the inside air to some extent and then sucked, so that the efficiency is good.

In addition to the above effects, since the cushion 1 is double-vacuum-packed by the inner bag 2 and the outer bag 4, the cushion 1 does not have to be made of a special material having high airtightness. The effect that it is unlikely to be affected by air leakage or the like is obtained. For example, when air leakage occurs in the outer bag 4, air enters between the outer bag 4 and the inner bag 2 and expands to the size of the outer bag 4, but It is possible to prevent expansion beyond the size.

When air leakage occurs in the inner bag 2, the cushion does not expand because there is no air between the outer bag 4 and the inner bag 2. In addition, since it is pressed by the press and sucked, the effect that the cushion is less likely to become wrinkled is obtained.

When the bag is put in the outer bag, it is not limited to three-fold but may be two-fold. The inner bag 2 may be made of polyethylene, for example, and the outer bag 4 may be made of, for example, a nylon layer sandwiched between polyethylene layers. The object of use of the cushion packaging method of the present invention is not limited to the cushion, but may be a futon or clothing.

[0018]

As described above, according to the present invention, since the cushion is double vacuum-packed, the bag is less likely to be damaged, and the cushion is prevented from inflating due to air leakage. Excellent space efficiency for storage and exhibition. That is, even if the airtight state of the bag is broken, it is possible to prevent the bag from expanding more than the outer bag.

Further, since the flat cushions are folded at least in two and then vacuum-packed again, a plate-like member having a certain degree of rigidity can be obtained, so that the handling can be facilitated.
