PURPOSE:To make a bulky article handy to stow and carry by a method wherein a wide opening part of the bag consisting of air-impermeable sheet is provided with seal pieces for hermetically sealing the bag, the bag is provided with an air draw hole having a chech valve formed in communication with the inside of the bag and a suction tube is made engageable with the aforesaid air draw hole. CONSTITUTION:An article (a) of great bulk, e.g. winter quilt, is forced into a bag from its wide opening part and the wide opening part is hermetically sealed at several places. The end part of a suction tube of an air suction device such as vacuum cleaner is inserted into a funnel-like outer tube 9 of an air draw hole having a check valve fixed to the bag and the suction operation of the air suction device is then started. The air between the article (a) and the bag and also the air inside the article itself are sucked out rapidly through the end part of the suction tube of the air suction device. For instance, the article of great bulk such as winter quilt is reduced to about 1/10-1/15 of the original volume and it becomes wholly as hard as a rigid plate.

Description

Detailed Description of the Invention (Field of Industrial Application) This invention is a decompression storage bag for bulky items that can store bulky household necessities such as futons, bedding, and cushions. Regarding.

(Prior Art) For example, conventional bags for storing futons, bedding, cushions, etc. have been designed to accommodate the bulkiness that futons, bedding, cushions, etc. originally have.

(Problems to be Solved by the Invention) Such conventional bags for futons, bedding, cushions, etc. merely protect their contents from dust or moisture.

In recent years, due to the soaring prices of land, etc., houses themselves have become smaller and their closets have become narrower, and the space for storing bulky items such as futons, bedding, cushions, and clothing is becoming restricted.

If futons, bedding, and cushions can be stored without bulk, the closet space can be used efficiently.

Furthermore, conventional futon bags are bulky and inconvenient to carry, and cannot completely prevent the generation and propagation of dust mites, mold, etc. inside the bag.

The present invention minimizes the volume of bulky items such as futons, bedding, and cushions stored inside the bag by sucking the air inside the bag. By keeping the interior under reduced pressure, it is convenient to store and carry, as well as being dehumidifying and mold-proof.
The purpose of the present invention is to provide a low-cost vacuum storage bag for bulky items that has excellent insect-proofing, sterilizing, and insecticidal effects.

(Means for solving the problem) In order to solve the above object, a wide opening is provided on one side of the bag made of a non-breathable sheet, and a sealing piece is attached to the opening to airtightly seal the bag. On the other hand, the bag body is formed with an air vent hole with a check valve that communicates with the inside thereof, and a suction tube of an air suction device can be fitted into the air vent hole with a check valve.

It is desirable to provide airtight seal pieces at a plurality of locations in the opening to improve internal airtightness.

Furthermore, the air-impermeable sheet can be a soft plastic sheet.

It is desirable that the lid or plug fit into the air vent hole with the check valve so as to press the check valve from the outside.

(Function) Bulky items such as futons, bedding, and cushions are pushed into the bag through the wide opening, and then the wide openings are airtightly sealed at multiple locations. On the other hand, if you insert the tip of the suction tube of an air suction device such as a vacuum cleaner into the air extraction hole with a check valve attached to the bag body and activate the suction operation of the air suction device, the suction tube of the air suction device will open. The tip not only sucks in the air in the gap outside the bulky object, but also rapidly suctions and depressurizes the air stored inside the bulky object itself, so that the bag body containing the bulky object undergoes a rapid thinning phenomenon. At the same time, an elastic solidification phenomenon occurs.

(Embodiment) In the embodiment shown in FIGS. 1 to 8, a bag f made of a non-breathable sheet such as a soft plastic sheet is used.
A wide opening (2) is provided in the width direction on one side of i+, and a plurality of sealing fasteners +3+ +31 are provided inside and outside the opening for airtight sealing. Bag body (1)
The internal seal fastener (3) has a convex part (4) and a concave part (
5), and the external seal fastener (3) of the bag body (1) consists of a convex part (i) and a concave part (5), at the end of the opening (2) of the bag body 11). A retaining part (2) such as a Velcro tape provided at the tip of the push piece (2) to fix the bag to the main body of the bag (tl), and a retaining part (2) such as a Velcro tape provided on the side of the bag ill. It is engaged with one side αD. On the other hand, on the opposite side of the opening (2) of the bag body (11), there is an air vent hole (6) leading to the inside of the bag body il+.
The holding part that formed the holder is attached.

A check valve (7) is formed in the air vent hole +6>. When air is sucked from the outside of the air vent hole (6) in the direction of the arrow from the tip (8) of an air suction device such as a vacuum cleaner (A), the check valve (the force is as shown in Figure 6) The air vent hole (6) tilts from the closed position to the open position. - (9) is a funnel-shaped outer cylinder that surrounds the outside of the air vent hole (6) and expands outward; ) is formed integrally with the holding part (to).When the air suction operation of the air suction unit is stopped, the inclined check valve (7) automatically moves the air vent hole (6) to the closing position. Return to the air vent hole (6) when the air inside the bag is removed.
) and the inside of the bag are under reduced pressure, so the check valve (7) is closed from the inside to keep the air vent hole (6) closed. Suction.

A cover plate αω is fitted to the outer end of the funnel-shaped cover (9), and a push part αυ is integrally formed inside the cover plate (G),
The lower end of the pushing part αυ presses the check valve (7). In addition, when fitting the cover plate αω to the outer end of the funnel-shaped cover (9), in order to securely fix the cover plate, the outer end of the funnel-shaped cover (9) should be fitted as shown in FIG. A small protrusion (2) is formed on the outer periphery of the lid, and a curved protrusion 0 is formed on the inside of the lid plate Ql, and a small protrusion (2) on the outer periphery of the outer end of the funnel-shaped cover (9) and the lid are formed. The curved protrusion 0 is made to engage with the inside of the plate aω.

Further, instead of the cover plate αω, a stopper (2) that presses against the check valve (7) may be used.

This bag body (1) is suitable for storing bulky items such as futons, bedding, cushions, or bulky clothing.

For example, as one side of a bulky fat bag, a winter futon is pushed into the inside of the bag through a wide opening, and the wide opening is airtightly sealed at multiple locations, while an air vent hole with a check valve is attached to the bag. If the tip of the suction tube of an air suction device such as a vacuum cleaner is inserted into the funnel-shaped outer tube (9) and the suction operation of the air suction device is activated, the tip of the suction tube of the air suction device can be removed from a bulky object. (In addition to sucking in the air in the gaps outside the al, it also rapidly sucks in the air stored inside the bulky item itself. For example, if it is a bulky item like a winter futon, the original volume will be reduced. The volume is as small as 1/l O-1/15, and the overall shape is a hard plate with bones.

Therefore, the bag containing the bulky material rapidly becomes thinner and at the same time becomes relatively elastic and hard plate-like.

In addition, in consideration of the case where the bag body (1) is filled with contents and stacked up, the surface of the bag body (1) may be formed with fine irregularities to prevent slippage.

(Effects) As described above, the present invention provides a wide opening on one side of a bag made of an air-impermeable sheet, and a seal piece for airtightly sealing the opening. Forms an air vent hole with a check valve leading to the inside thereof, and serves as a vacuum storage bag that allows the suction tube of the air suction device to be fitted into the air vent hole with a check valve. ,
If it is suitable for bulky items such as cushions and clothing,
Since the air contained therein can be almost completely removed, the volume can be reduced to about 115 to 1/20 of the original capacity, allowing for efficient use in closets, etc.

Furthermore, bulky objects that are soft in their original state become low-bulky objects that are somewhat elastic and solid, making them easier to carry and having the effect of significantly reducing transportation costs for mass transportation. .

Moreover, since the inside of the bag maintains a reduced pressure state, it has excellent dehumidification, mold prevention, insect prevention, sterilization, and insecticidal properties, and can completely prevent the growth and reproduction of mites, mold, etc. inside the bag. .

In order to confirm the effect, the inventor set a power rate of 135W.
, degree of vacuum 826 m of mercury, air volume 1. OT@” cleaning 1
Using Mf81, we vacuum-operated the bag of a winter futon, and after about 3 months, we opened the bag opening again to let air flow in. Within just a few minutes, the bulky item returned to almost its original condition. I confirmed that it was restored.
