Description

The present invention relates to an exhaust device for a compression storage bag that is used by being assembled in a compression storage bag to compress and store stored items such as futons, cushions, and clothes.

Articles such as futons, cushions, and clothing are preferably in a bulky state containing a large amount of air when used. However, its bulkiness becomes a problem during storage.

Therefore, in order to prevent these from becoming bulky when storing the futon, a compression storage bag is used. The compression storage bag is equipped with an exhaust valve consisting of a check valve. When a futon is stored in the compression storage bag, for example, when the intake port of a vacuum cleaner is applied to the exhaust valve for suction, the exhaust valve that closes the exhaust port is electrically cleaned. It is opened by the suction force of the machine, and the air in the compression storage bag is discharged to the outside through the exhaust port to remove the air from the futon and compress it. When suction is stopped, the inside of the compression storage bag becomes negative pressure and the outside becomes positive pressure, and the exhaust valve closes the exhaust port due to this pressure difference, and the air inside the futon is evacuated to maintain the compressed state. Can be done.

However, in such a compressed storage bag, if the intake port is blocked by a part of the futon that is sucked in at the time of exhausting, the exhaust becomes stagnant and quick exhaust cannot be performed. Therefore, Patent Document 1 discloses an exhaust valve that prevents the intake port from being blocked by the futon during exhaust.

In Patent Document 1, "a body 4 having an air flow passage R communicating with the inside of the bag 1 and an upright plate for holding the contents so that the contents of the bag 1 do not come into contact with the air flow passage R of the body 4". No. 7 describes an exhaust valve mechanism Q having a fuselage 4 formed radially outward from the periphery of the air flow passage R of the fuselage 4. Then, at the time of degassing, it is possible to prevent the air flow passage R from being blocked by the contained matter, and it is possible to degas the inside of the bag.

However, when the exhaust valve mechanism described in Patent Document 1 is used, the intake port is not directly blocked by the futon at the beginning of the exhaust, but a part of the futon gets into the space between the upright plates as the exhaust progresses. The area around the air intake may be blocked.

When it is blocked in this way, the air flow is obstructed by the clogging of the futon, and it takes a very long time to exhaust the air sufficiently. In addition, if it takes a long time, an extra load is applied to the vacuum cleaner for a long time, which may cause a failure of the vacuum cleaner.

An object of the present invention is to provide an exhaust tool for a compressed storage bag that solves the above-mentioned problems and completes exhausting in a short time without blocking the intake port by internal stored objects even if exhausting is advanced. It is in.

The exhaust tool 1 is composed of an inner member 2 and an outer member 3 made of a hard member made of a hard synthetic resin material or the like, and a valve member 4 made of a soft member made of an elastic synthetic resin material, a rubber body or the like. It is composed of three members, and a valve member 4 is arranged between the inner member 2 and the outer member 3.

The inner member 2 has a valve holding cylinder 2a in the central portion, and for example, eight plate-shaped partition walls 2b are arranged radially outward at an equal angle around the valve holding cylinder 2a. A valve seat portion 2c having an annular flat upper surface is connected to the upper outer end of each partition wall 2b, and a valve holding cylinder 2a and an upper edge of the partition wall 2b appear in the inner edge of the valve seat portion 2c. The space between the partition walls 2b on the inner edge of the valve seat portion 2c is an intake air introduction window 2d.

An annular lower holding plate 2e is connected around the valve seat portion 2c, and the valve seat portion 2c has a shorter cylindrical shape higher than the lower holding plate 2e and has a concave groove around the valve seat portion 2e. 2f is formed in a ring shape.

On the lower surface of the lower holding plate 2e, for example, 12 plate-shaped partition walls 2g are arranged radially at an equal angle with the valve holding cylinder 2a as the center, and the partition walls 2g project downward from each other.

The lower edge of these partition walls 2g is substantially at the same position as the lower edge of the partition wall 2b, and each tip of the partition wall 2g extends further to the outside than the outer circumference of the annular lower holding plate 2e, and lower holding. upper portion 2h is located in front of the plate 2e, contiguous part of the partition wall 2g is inclined somewhat s obliquely downward.

Further, an annular frame portion 2i is arranged on the outside of the partition wall 2g, and the tips of the partition walls 2g are connected to the inside of the annular frame portion 2i. Further, the lower edge of the annular frame portion 2i is substantially at the same position as the lower edge of the partition wall 2g.

The outer member 3 is fitted into the valve seat portion 2c of the inner member 2 from above to form a short cylindrical valve chamber 3a having an inner space, and the valve seat is formed on the inner lower edge of the valve chamber 3a. A locking piece 3b that engages with the recess 2f at the bottom of the portion 2c is provided. Further, for example, three exhaust windows 3d are provided on the top 3c of the valve chamber 3a. Further, around the lower part of the valve chamber 3a, an upper holding plate 3e having the same shape is formed so as to overlap the lower holding plate 2e of the inner member 2 via a sheet material of a compression storage bag described later. The three ribs 3f provided on the upper part of the upper holding plate 3e are for reinforcement and also play a role of pressing the outer member 3 when it is attached to the inner member 2.

The valve member 4 includes an elastic, soft, thin-walled disc-shaped, dish-shaped valve body 4a, and a shaft portion 4b extending downward from the center of the valve body 4a and inserted into the valve holding cylinder 2a. The valve body 4a is placed on the valve seat portion 2c and arranged in the valve chamber 3a.

The valve body 4a operates by the pressure difference between the intake air introduction window 2d side and the valve chamber 3a side of the outer member 3, and when the pressure on the intake air introduction window 2d side is larger than the pressure on the valve chamber 3a side, the valve is valved. When the body 4a rises to open the intake air introduction window 2d and the pressure on the intake air introduction window 2d side is smaller than the pressure on the valve chamber 3a side, the valve body 4a descends to close the intake air introduction window 2d.

The exhaust tool 1 of the present embodiment is sold as a single unit, but most of them are assembled in the exhaust hole portion of the compression storage bag and are commercially available. The compression storage bag made of a synthetic resin sheet material for storing stored items such as futon F inside has air-blocking property, transparency, and flexibility.

The compression storage bag has a storage opening with a sealing fastener attached to the edge for storing the futon in a sealed state, and a circular exhaust hole for attaching the exhaust tool 1 for exhausting the internal air. There is a section. The diameter of the exhaust hole portion substantially coincides with the diameter of the valve seat portion 2c.

When assembling the exhaust tool 1 to the compression storage bag, as shown in FIG. 5, the valve seat portion 2c of the inner member 2 is inserted into the exhaust hole portion of the compression storage bag B, and the peripheral edge of the exhaust hole portion is lowered. It is airtightly joined to the holding plate 2e by melting or adhering. Subsequently, when the valve member 4 is attached to the inner member 2, the shaft portion 4b is inserted into the valve holding cylinder 2a, and the valve body 4a is placed on the valve seat portion 2c, the valve body 4a covers the intake air introduction window 2d. It will be.

Next, the outer member 3 is brought into contact with the inner member 2 to lock the locking piece 3b of the valve chamber 3a to the recess 2f of the valve seat portion 2c. As a result, the valve chamber 3a covers and fits the valve seat portion 2c, and the peripheral edge of the exhaust hole portion of the compression storage bag B adhered to the lower holding plate 2e is fitted with the lower holding plate 2e of the inner member 2 and the outer member. It is sandwiched between the upper holding plate 3e of 3 and the assembly of the exhaust tool 1 to the compression storage bag B is completed. In this state, the compressed storage bag B is folded and put on the market.

At the time of use, the user expands the compression storage bag B to which the purchased exhaust tool 1 is assembled, stores, for example, a futon inside from the storage opening of the compression storage bag B, and then closes the storage opening to make a fastener. Seal with.

Next, the suction port S of the vacuum cleaner is brought into contact with the front side of the valve chamber 3a of the exhaust tool 1 to suck the internal air from the exhaust window 3d. Then, the internal space of the valve chamber 3a becomes a negative pressure, and as shown in FIG. 6, the valve body 4a of the valve member 4 covering the intake air introduction window 2d rises in the valve chamber 3a along the valve holding cylinder 2a. Then, it is separated from the valve seat portion 2c and the intake air introduction window 2d is opened.

Therefore, the air in the compression storage bag B, particularly the air contained in the futon F, is sucked out, and this air is guided by the partition wall 2g below the partition wall 2g of the inner member 2 and from the intake window 2j to the inside of the inner member 2. Then, a large amount of air flows into the air intake window 2d, which is further partitioned by the partition wall 2b, and is sucked into the electric vacuum cleaner from the exhaust window 3d of the outer member 3 through the air intake introduction window 2d. As the exhaust progresses, the futon F tries to enter between the partition walls 2b, but due to the presence of the annular frame portion 2i, the futon F can only enter to a predetermined height.

The air flow toward the inside of the partition wall 2g through the intake window 2j is not blocked by the futon F, and the air flow passage leading to the intake introduction window 2d is always secured.

It is possible to exhaust the air in the futon F of the entire futon F through this air flow path. Therefore, the air in the compression storage bag B can be quickly exhausted without obstructing the flow of air with respect to the intake air introduction window 2d due to clogging of the futon F. By providing the annular frame portion 2i on the outside of the partition wall 2g in this way, the intake port is not blocked by the futon F during exhaust, and an air flow passage is secured through the intake window 2j, which is short. Exhaust can be completed in time.

When the exhaust is continued and the futon F inside is sufficiently compressed, as shown in FIG. 7, the peripheral edge of the exhaust hole portion of the compression storage bag B finally sticks to the intake window 2j to form the intake window 2j. It will be blocked.

In this state, when the suction by the vacuum cleaner is stopped and the suction port S of the vacuum cleaner is removed from the exhaust tool 1, the valve body 4a becomes the valve seat portion 2c as shown in FIG. 7 due to the negative pressure in the compression storage bag B. The inside of the compression storage bag B is maintained in a sealed state by being adsorbed by the intake air introduction window 2d. As a result, the futon F can be stored for a long period of time by a closet or the like while being shrunk in the compression storage bag B.

To remove the futon F from the compressed storage bag B, open the fastener of the storage opening, the outside air flows into the compressed storage bag B, and the futon F absorbs the air and restores its original shape. ..
