Abstract

PURPOSE:To provide a compressed housing bag which is improved in the airtightness when it is kept compressed and can be manufactured at low costs. CONSTITUTION:Contents are put into a flat bag 10 of synthetic resin and its mouth is sealed temporarily with a clip 30, and then, inside air is sucked out of a suction port 20. After suction is completed, in order to put the suction port 20 out of a sealing range, substantial sealing is made by welding with an iron. Accordingly, during keeping the bag 10 in a compressed state, air does not flow in through the suction port 20, whereby airtightness can be retained.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compression storage bag for compressing and storing textile products such as futons and sweaters, and particularly to a compression storage bag that maintains sufficient airtightness during storage.

0002

[Prior Art and Problems of the Invention] As a compression storage bag, Fig. 5
There is something like the one shown below. This compressed storage bag is a flat bag 51 made of synthetic resin with a suction port 52 equipped with a valve. After placing a futon, etc. into the flat bag 51, the opening is closed by welding with an iron. After the air inside is suctioned through the suction port 52 by a household vacuum cleaner, the suction port 52 is closed and compressed and stored.

[0003] However, with such a compressed storage bag, when compressed and stored for a long period of time, air gradually enters through the suction port 52, resulting in a decrease in the compressive force. In order to solve this problem, it may be possible to improve the airtight performance of the suction port 52, but another problem arises, such as increased cost.

SUMMARY OF THE INVENTION An object of the present invention is to provide a compressed storage bag that maintains sufficient airtightness even when compressed and stored for a long period of time and can be manufactured at low cost, and a method for sealing the same.

[0005]

[Means for Solving the Problems] In order to solve the above problems, the stored items are compressed and stored by sealing a synthetic resin bag containing stored items and sucking the air inside through a suction port. In the compressed storage bag, the bag is provided with a temporary sealing part and a permanent sealing part sequentially from the mouth side, and the suction port is provided between the main sealing part and the temporary sealing part. It is. In addition, as for the sealing method of this compression storage bag, first,
After putting the stored items in the bag and temporarily sealing the opening, the air inside the bag is sucked through the suction port, and then the final sealing is performed at a position where the suction port is out of the sealed area.

[0006]

[Operation] In the main sealed state, since the suction port is located outside the main sealing area, air will not enter into the bag from the suction port during compressed storage.

[0007]

[Embodiments] Hereinafter, embodiments will be explained with reference to the drawings.

As shown in FIG. 1, this compressed storage bag 1 has the following features:
It is composed of a flat bag 10 made of synthetic resin, a suction port 20 that is detachably attached to the flat bag 10, and a clip 30 for temporarily sealing the opening of the flat bag 10.

As shown in FIG. 2, the suction port 20 includes an outer member 21 having a valve 21a and an outer member 21.
and an inner member 22 that is fitted and fixed to the inner member 22. When attaching to the flat bag 10, as shown in the same figure, when the sheet on one side of the flat bag 10 is inserted between the two members 21 and 22 and fitted together, the sheet will be torn off naturally by the fitting part. Air circulation holes are formed.

The clip 30 includes an elongated cylindrical member 31.
and a receiving member 32 having a groove 32a into which this cylindrical member 31 is fitted. By inserting a temporary sealing part A shown in chain lines in FIG. 1 between both members 31 and 32, the flat bag 10 is temporarily Can be sealed.

[0011] The main sealing part B shown by the chain line in FIG. 1 is a part that is sealed by welding with an iron. The main sealing part B may be formed by forming the entire flat bag 10 with heat-welding resin so that the user can arbitrarily decide its position, or by heat-welding it partially on the inner surface of the flat bag 10. It is also possible to provide a section and make only that area the main sealing section.

When a textile product such as a futon is placed in the compressed storage bag 1 constructed as described above and compressed and stored, the method shown in FIG.
As shown in a), after the suction port 20 is attached between the temporary sealing part A and the permanent sealing part B of the sheet on one side of the flat bag 10, the stored items are put into the bag. After temporarily sealing the temporary sealing part A with the clip 30 and sucking the air inside through the suction port 20, as shown in FIG. The final sealing is performed by welding the sealing portion B with an iron.

[0013] After welding the main sealing part B, if the suction port 20 and the clip 30 are removed as appropriate and the front end of the main sealing part B of the flat bag 10 is cut off, it will not get in the way during storage. Furthermore, the removed suction port 20 and clip 30 can be used for next storage, which is economical.

FIG. 4 shows another embodiment. This compressed storage bag 2 has a different form of the suction port in the previous embodiment. That is, as shown in FIG. 3(b), both members 31 and 32 of the clip 30 have cutout portions 33
As shown in Figure (a), a suction tool C with a straw-shaped tip is inserted directly into this part from the opening of the flat bag 10 to perform suction. In this case, even if the suction tool C is removed after the suction is completed, the state will be maintained for about one hour, and the welding can be done with an iron during this time.

As described above, in the above-mentioned compressed storage bag, since there is no suction port 30 in the sealed area of the flat bag 10 in the compressed storage state, that is, in the fully sealed state, air does not escape from this area. There is no inflow, and airtightness is improved compared to conventional ones. Further, since the temporary sealing is performed in advance with the clip 30, the final sealing portion is less likely to wrinkle due to suction, and the airtightness of the welded portion is not impaired.

[0016]

[Effects] As described above, the compression storage bag according to the present invention has
The structure is such that the air inside is sucked out in the temporarily sealed state, and the final seal is re-sealed at a position where the suction port leaves the sealed area, eliminating the inflow of air from the suction port and improving airtightness during compressed storage. It cannot be damaged. Furthermore, since the airtight performance of the suction port is not particularly improved, it can be manufactured at low cost like conventional products.
