[0010]

1 is a plan view showing an embodiment of the present invention, and FIG. 2 is a sectional view taken along line II--II in FIG.

The air bleeding member 10 is particularly used for a compression storage bag 11 as shown in FIGS. 3, 4 and 5, for example. The compression storage bag 11 includes a flat bag body 12 having an opening 14. The bag body 12 is formed, for example, in a rectangular planar shape. The bag body 12 is formed of an air-impermeable synthetic resin material that does not allow air to pass through. The opening 14 is formed at one end in the longitudinal direction of the bag body 12 and from one end to the other end in the width direction thereof. Through the opening 14, the bag 12 can accommodate items such as a futon, a blanket, and heavy clothing.

In this case, the bag body 12 includes, for example, a rectangular base material 16. The base material 16 has a so-called laminated structure in which a plurality of air-impermeable plastic films are stacked and bonded together. In this embodiment, a plurality of plastic films, for example, plastic films using four materials such as EVAL, polyethylene, nylon and linear lauren are used.

The features of these materials will be described. That is, since EVAL has a low melting temperature, it is easily welded at low and medium temperatures. Polyethylene has strength as a surface protective film. Nylon is impermeable to air and therefore has excellent insulation properties in a vacuum pack. Due to its tenacity, Linear Loren is resistant to bending and scratches.

The substrate 16 is formed by sequentially laminating EVAL, polyethylene, nylon, polyethylene and linear lauren in this order. In this case, the base material 1
6 is laminated such that polyethylene is arranged on both sides of nylon. Air leakage is prevented by protecting the nylon surface with polyethylene. Also,
The base material 16 serves as an inner surface of the bag body 12, and is laminated on the surface to be welded with, for example, an iron so that EVAL is arranged. In this embodiment, the substrate 16 is formed to have a thickness of 80 microns, for example.

Incidentally, 100% virgin material is used for these plastic films, and no recycled material is used at all. Therefore, compared to a plastic film using a recycled synthetic resin material, there is no concern about air leakage, and the touch is soft. Further, the base material 16 is subjected to insect repellent, mildewproof and deodorant treatment. The laminating method of these plastic films includes, for example, a dry laminating method, a hot melt laminating method, an extrusion laminating method and a co-extrusion laminating method, which can be appropriately selected. In this example, a coextrusion laminating method is selected, for example using multiple extruders.

Further, the base material 16 is formed in, for example, a flat tubular shape. The base material 16 formed in a tubular shape is formed as the bag body 12 by welding one opening portion thereof. The bag body 12 may be formed, for example, by stacking two base materials 16 and heat-sealing or adhering the peripheral edges of the base materials 16 excluding one end side in the longitudinal direction.

The bag 12 has, for example, two valves 1
8a and 18b are formed. Valves 18a and 18b
Is formed into a flat tubular shape with a plastic film, for example. The valves 18a and 18b are formed of a plastic film having the same laminated structure as the base material 16. In addition, these valves 18a and 18b are
It is formed by the same manufacturing method as. Also, these valves 18a
And 18b may be formed, for example, by stacking two strip-shaped laminated plastic films and thermally welding or adhering both ends in the width direction thereof.

Hole 20a in valve 18a and hole 2 in valve 18b
0b respectively communicates the inside of the bag body 12 and the outside of the bag body 12. These holes 20a and 20b have a function as a suction port for sucking air from the inside of the bag body 12 to reduce the pressure.

These valves 18a and 18b are the bag 1
2 is formed at the other end in the longitudinal direction and at one end and the other end in the width direction thereof. Valves 18a and 1
8b is formed such that one longitudinal end thereof extends into the bag body 12 and the other longitudinal end thereof extends out of the bag body 12.

In this case, the bag 12 has the valves 18a, 18
Mounting portions 22a and 22b for mounting b are formed. These mounting portions 22a and 22b are formed at the other end in the longitudinal direction of the bag body 12 and at one end and the other end in the width direction thereof, respectively. These mounting portions 22a
And 22b are cut holes 24a and 2a obtained by obliquely cutting both ends of the side of the bag body 12 that faces the opening 14.
4b. These cut holes 24a and 24b are formed to be slightly larger than the width of the valves 18a and 18b. The valve 18a and the valve 18b are respectively
It is attached to the bag body 12 by being inserted into and fixed to the attachment portions 22a and 22b. Valves 18a and 1
The outer surfaces of the middle portions in the longitudinal direction of 8b are fixed to the inner surface of the bag body 12, respectively. Valves 18a and 18
The outer surface of the middle portion of b and the inner surface of the bag body 12 are fixed by, for example, welding or bonding. The valves 18a and 18b are fixed to the bag body 12 so that their holes 20a and 20b are not blocked.

Therefore, these valves 18a and 18
The outer valve portion 2 located outside the bag body 12 is shown in FIG.
6a, 26b and the inner valve portion 28 located in the bag body 12
a and 28b are formed. The outer valve portions 26a and 26b are formed to be longer than the inner valve portions 28a and 28b, for example. When the bag 12 is evacuated to the valves 18a and 18b, the suction nozzles of, for example, household vacuum cleaners are inserted from the outer valve portions 26a and 26b.
In addition, the inner valve portions 28a and 28b have a function of sealing the inside of the bag body 12 when the inside of the bag body 12 is in a vacuum state because the inner surfaces of the inner valve portions 28a and 28b are in close contact with each other. Have.

In this compression storage bag 11, as shown in, for example, FIGS. 6 and 7, the inside of the bag body 12 is decompressed to a vacuum state by sucking air in the bag body 12. In this embodiment, for example, a household vacuum cleaner 120 is used to reduce the pressure of the air inside the bag 12 to a vacuum state. In addition, the vacuum cleaner 120 is used for the bag 1
When sucking the air in 2, the two valves 18a and 18
It is sufficient to suction from the hole of either valve of b.

In this embodiment, for example, as shown in FIG.
As shown in (B), one valve 18a of the compression storage bag 11
In the outer valve portion 26a of the
For example, the suction nozzle 120b is inserted. At this time, the air vent member 10 is attached to the suction nozzle 120b. The air vent member 10 is a tubular pipe body 3
0, and a hook portion 32 having, for example, a J-shaped tubular shape is formed at one end of the pipe body 30. The pipe body 30 and the hook portion 32 are integrally formed of a synthetic resin material such as high-pressure poly, and are formed in a J shape as a whole. In this case, the length of the pipe body 30 is the same as that of the air vent member 10.
When the valve is attached to the suction nozzle 120b of the electric vacuum cleaner 120, the valve 18a
Formed longer than the length of. In this embodiment, the pipe body 30 and the hook portion 32 have an outer diameter of 7 mm,
It is formed with an inner diameter of 5 mm. The length of the pipe body 30 is, for example, 280 mm, and the length of the hook portion 32 is, for example, 70 mm.

The air vent member 10 has a hook portion 3
2 is attached to the suction nozzle 120b by being locked to the tip of the suction nozzle 120b. Air vent member 1
No. 0 is attached to the suction nozzle 120 so that the pipe body 30 is along the side surface of the suction nozzle 120b. Further, the suction nozzle 120b is inserted into the outer valve portion 26a of the valve 18a with the air vent member 10 attached. In this case, the suction nozzle 120b to which the air bleeding member 10 is mounted has the pipe body 30 of the air bleeding member 10
Is inserted into the outer valve portion 26a so that the other end of the is projected outward from the outer valve portion 26a.

Therefore, when the air inside the bag 12 is sucked while the air bleeding member 10 is attached to the suction nozzle of the electric vacuum cleaner 120, an air escape path is created, and the air inside the bag 12 and the bag are Air outside 12 is vented. Therefore, if the air vent member 10 is used, the air in the bag body 12 can be continuously sucked for a long time without burdening the motor of the electric vacuum cleaner 120.

Further, from the outer valve portion 26a of the valve 18a to the bag body 1
When the air inside 2 is sucked to make the inside of the bag 12 into a vacuum state, the pressure difference between the inside of the bag 12 and the outside of the bag 12 creates a force to press the outer surface of the inner valve portion 28a. The inner surfaces of the inner valve portion 28a are in close contact with each other. Therefore, the vacuum state inside the bag body is maintained and the inside of the bag body 12 can be sealed. Further, if the hole 20a at the inlet portion of the outer valve portion 26a is heat-welded with, for example, an iron, the suction of air from the outside of the bag body 12 can be completely prevented. The outer valve portion 26
Even when air enters from a, a force for pressing the inner valve portion 28a is generated, and the inner surfaces of the inner valve portion 28a are in close contact with each other.

Next, a working process of compressing and storing a futon, for example, by using the compression storage bag 11, will be described mainly with reference to FIG.

First, in the compression storage bag 11, FIG.
As shown in (A), the futon 100 has the opening 1 of the bag body 12.
You can fold it from 4 and put it in. In this case, it is preferable that the futon 100 is dried in the sun in advance or is previously dried in a futon dryer. And, the futon 100 is shown in FIG.
As shown in (B), the valves 18a and 18b are brought close to each other,
The edges of the opening 14 are aligned. Furthermore, the opening 1
For example, an iron is gently pressed against the edge portion A of 4 at a low temperature to heat-weld it, and the opening portion 14 is sealed. Opening 14
When applying an iron to, for example, temporarily attach it at about four places and press it slowly and carefully so that it does not wrinkle. If the surface of the iron is iron, put a handkerchief or patch cloth and apply the iron over it.
The end of one valve 18b is heat-sealed in advance with an iron or the like to be hermetically sealed.

Then, the outer valve portion 26a of the other valve 18a.
As shown in FIGS. 7 (A), (B) to FIG. 8 (C), the suction nozzle 120b of the household vacuum cleaner 120 is inserted into. In this case, the air vent member 10 is attached to the suction nozzle 120b in advance. This air vent member 10 is
The suction nozzle 120b of the electric vacuum cleaner 120 is connected to the outer valve portion 26a.
When sucking the air inside the bag 12 by inserting the
The other end of the pipe main body 30 of the air vent member 10 has the outer valve portion 26.
The suction nozzle 120b is mounted so as to project to the outside from a. Then, the air inside the bag 12 is evacuated to the vacuum cleaner 12
By sucking at 0, the inside of the bag body 12 is depressurized. At this time, since the inner surfaces of the inner valve portion 28a of the valve 18a are in close contact with each other, the inside of the bag body 12 is sealed. Further, the suction nozzle 120 of the electric vacuum cleaner 120 is inserted from the outer valve portion 26a of the valve 18a.
8b, the wrinkles of the outer valve portion 26a of the valve 18a are extended in the direction of the arrow as shown in FIG.
By pressing the end B of the valve with an iron, the valve 18a
The hole 20a can be completely sealed.

In this way, the futon 100 put in the bag 12 is compressed and stored. Further, if the portion of the valve 18a that has been welded by the iron is cut and used with as little waste as possible, it can be used repeatedly several times. Moreover, this compression storage bag 11
For example, anyone can easily work using a vacuum cleaner and iron at home.

In this compression storage bag 11, the outer shape of the entire bag body 12 becomes smaller as the pressure reduction progresses, and the bag body 12
And the futon 100 accommodated in the bag body 12 is compressed. Therefore, for example, the stored items such as the futon, the blanket, and the thick clothing can be compactly stored without being bulky. In this compression storage bag 11, for example, the stored items are 1/3.
It is compressed and stored. Therefore, the storage space for the stored items can be small, and the storage space can be effectively utilized.

Next, Table 1 below shows the results of a comparison test of the suction performance of this compression storage bag 11 with that of the conventional one. As a suction test method, for example, a commercially available household vacuum cleaner was used to measure the time until, for example, one cotton comforter was compressed and stored almost completely. In addition, the vacuum cleaner used is
It was operated at the strongest suction level.

[0033]

[Table 1]

As shown in Table 1, it is apparent that the compression storage bag 11 has a shorter time for sucking the air in the bag 12 than the conventional one. Therefore, the compression storage bag 11 requires less work time for compressing and storing the stored items than the conventional one. Moreover, this compression storage bag 11
In the case of using, since the suction time by the cleaner is short, the motor of the cleaner is not burdened and there is no risk of the cleaner breaking down.

Table 2 below shows the results of a comparative test of the thermal adhesiveness of the compression storage bag 11 with that of the conventional one. As a test method for heat adhesion, a commercially available iron is used, the scale of the iron is set to each temperature, and the iron is pressed for a predetermined time to heat-bond each compression storage bag.
Then, after the temperature of the bonded portion was cooled, it was peeled off by hand to check the bonding condition. The test operation was performed 5 times for each judgment.

[0036]

[Table 2]

As shown in Table 2, this compression storage bag 11 has a bag body 12 and valves 18a, 1 as compared with the conventional one.
Since a plastic film made of EVAL is laminated on the inner surface of 8b, which is to be heat-welded, the opening 14 of the bag 12 and the suction ports of the valves 18a and 18b can be exposed to low temperature and It can be easily welded at medium temperature.

Further, Table 3 below shows the results of the endurance test of the electric vacuum cleaner when suction work was performed for a long time using the air vent member 10. As a method of the durability test, a commercially available electric vacuum cleaner is used, and after the air vent member 10 is attached to the suction nozzle of the electric vacuum cleaner, for example, a cotton comforter is vacuum-packed, further suction work is performed. It was Then, I checked whether the vacuum cleaner stopped operating, and whether there was abnormal noise or abnormal heat.

[0039]

[Table 3]

When a suction work is performed using this air vent member 10, as shown in Table 3, no abnormality is found in the vacuum cleaner even if suction is continued for 5 to 20 minutes, for example. By using this air vent member 10, it is possible to continuously suck air in the bag body for a long time without imposing a load on the motor of the electric vacuum cleaner. Therefore, even if the user sits down for some reason during the suction work, it is not necessary to switch off the vacuum cleaner each time, unlike the conventional case.
The suction work can be continuously performed. That is, if the air in the bag body 12 is sucked using the air vent member 10, the suction operation can be interrupted while the air is in the degassed state.

In this compression storage bag 11, it is possible to easily store the contents such as a futon in a compressed manner in a short time. Moreover, in the compression storage bag 11, the intake of air from the outside of the bag body 12 can be prevented by the valves 18a and 18b. Therefore, the vacuum state in the bag 12 can be maintained for a long time even after being compressed and stored.

In the above embodiment, the air vent member 10
Has a hook portion 32 at one end thereof and is formed in a J shape as a whole, but the air vent member 10 may be formed of only the pipe body 30, for example. In this case, the air vent member 10 is attached to the side surface of the suction nozzle 120b with, for example, an adhesive tape or an adhesive. In this way, the attachment means of the air vent member 10 to the suction nozzle 120b can be changed as appropriate. Further, in the above-described embodiment, the suction nozzle 120b of the electric vacuum cleaner 120 has the outer valve portion 2
Although it has been inserted into 6a, the hose 120a of the electric vacuum cleaner 120 may be inserted, for example. in this case,
The hook portion 32 of the air vent member 10 has a hose 120.
It is locked in the hole a and is attached to the hose 120a. Further, in the above-described embodiment, the air vent member 10 may be formed in a polygonal rectangular tube shape whose cross-sectional shape is, for example, a triangular shape, a quadrangular shape, or the like.

In the above-described embodiment, the base material 16 of the bag body 12 has a laminated structure in which Eval, polyethylene, nylon, polyethylene and linear lauren are sequentially laminated from the lower layer. For example, a laminated structure in which Eval, polyethylene, linear lauren, polyethylene, nylon, polyethylene, linear lauren, polyethylene and Eval are sequentially laminated from the lower layer may be formed. in this case,
Since linear loren and polyethylene are formed between the polyethylene and the nylon, the tenacity is further enhanced, and bending and scratches are further enhanced.
