When the inside of the bag is depressurized, the inner surfaces of the valves are in close contact with each other, so that suction of air from the outside after compression and storage can be prevented, so that the inside of the bag can be depressurized in a shorter time than before.

Since the ultraviolet ray is absorbed by the ultraviolet ray absorbing layer, sunburn and the like of the bag due to light can be prevented, and the sealing property of the bag can be prevented from lowering.

The movement of the opening / closing member at one end and the other end of the opening of the bag is regulated by the opening / closing restricting portion, and one end and the other end of the opening are closed. The suction of air from the opening / closing tool at one end and the other end can be prevented. Therefore, it is possible to further shorten the compressed storage time of the stored items.

When a vacuum nozzle of a vacuum cleaner is inserted into a suction port of a valve to suck air in the bag and decompress the air, the suction nozzle of the vacuum cleaner projects so that one end of the air release member protrudes outside the bag. As a result, the inside and the outside of the bag body are ventilated, and an escape route for air is created. Therefore, the pressure inside the bag can be reduced without imposing a load on the motor of the vacuum cleaner. For this reason, even a feather product such as a duvet or a down jacket, which has conventionally required a suction time, can be easily and safely compressed and stored.

The above and other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

FIG. 3 is a sectional view taken along line III-III in FIG.
The compression storage bag 10 includes, for example, a flat bag 12 having a rectangular planar shape. The bag body 12 is formed of an air-impermeable non-breathable synthetic resin material. The bag body 12 has the opening 1
4 The opening 14 is formed at one end in the longitudinal direction of the bag body 12 from one end to the other end in the width direction. In this case, at one end and the other end of the opening 14, opening / closing restricting portions 15a and 15b that close the one end and the other end of the opening 14 by a predetermined length are formed.
The opening / closing restricting portions 15a and 15b allow the opening 1 of the bag body 12 to be opened.
4 is formed so that the effective opening length is smaller than the entire length from one end to the other end of the bag body 12 in the longitudinal direction. Therefore, the opening 14 is formed in the bag body 12 except for the seal portions 15a and 15b. This opening 1
Through the bag 4, beddings such as futons and blankets and other storage items such as thick clothing can be stored in the bag body 12.

The bag body 12 includes a base member 16 having a rectangular shape and a flat cylindrical shape when viewed from a plane. The base material 16 has a so-called laminate structure in which a plurality of non-breathable plastic films are stacked and bonded. In this embodiment, a plurality of plastic films such as high-density polyethylene, low-density polyethylene, and polyamide (nylon) are used. Therefore, the features of these materials will be described. Low density polyethylene has strength as a surface protective film. Since polyamide (nylon) does not allow air to pass through, it has excellent insulation properties in a vacuum pack. High-density polyethylene is resistant to bending and scratching due to its tenacity.

As shown in FIG. 3, the base 16 is laminated in order of a high-density polyethylene film 16a, a low-density polyethylene film 16b, a polyamide film 16c, a low-density polyethylene film 16b, and a high-density polyethylene film 16a. Formed by
In this case, the base material 16 is laminated so that the low-density polyethylene film 16b is disposed on both surfaces of the polyamide film 16c. By protecting the surface of the polyamide film 16c with the low-density polyethylene film 16b, air leakage can be further prevented, and strength against bending and scratches can be obtained.

Further, the high-density polyethylene film 16a on one main surface side of the base material 16 contains an ultraviolet absorber. Therefore, the high-density polyethylene film 16a on one main surface side of the base material 16 is formed as an ultraviolet absorbing layer, and can cut off ultraviolet light.
In this embodiment, the ultraviolet absorbent is contained in the high-density polyethylene film 16a located on the outer surface of the bag body 12 described later. The high-density polyethylene film 16a on the other main surface side of the base material 16 is subjected to insect repellent, fungicide and deodorant treatment. In this embodiment, a high-density polyethylene film 16a located on the inner surface of the bag
Insect repellent, fungicide and deodorant treatments are applied.

Incidentally, these plastic films are made of 100% virgin material, and no recycled material is used. Therefore, compared to a plastic film using a recycled synthetic resin material, there is no fear of air leakage, and the touch is soft touch. Examples of the laminating method of these plastic films include, 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 embodiment, for example, a co-extrusion laminating method using a plurality of extruders is selected.

Further, the substrate 16 thus laminated is formed in a flat cylindrical shape. The base material 16 formed in a cylindrical shape is formed as the bag body 12 by welding one open portion thereof. The bag body 12 may be formed, for example, by laminating two base materials 16 and heat-welding or bonding the peripheral edge of the bag except for one end in the longitudinal direction.

Further, around the opening 14 of the bag body 12,

The two ridges 26, 26 are formed at predetermined intervals in the width direction of the strip 24. The protruding ridge portion 26 is formed of a columnar support piece 28a having a substantially trapezoidal cross section and a columnar fitting piece 30a having a substantially hexagonal cross section, for example. The strip 24, the support piece 28a, and the fitting piece 30a are integrally formed of an elastic synthetic resin material or the like. In this case, the hypotenuse 32 of the support piece 28a and the hypotenuse 32
It is preferable that 0 <θ <180, where θ (degree) is the angle of the angle formed by the adjacent fitting piece 30a and the one side 34 of the fitting piece 30a. In this embodiment, the cross-sectional shape of the fitting piece 30a is substantially hexagonal. However, the fitting piece 30a may be formed in another polygon such as a triangular or quadrangular cross-section.

The female body 22 meshing with the male body 20 includes a rectangular band portion 36, and the band portion 36 is formed with two concave stripe portions 38 extending in the longitudinal direction. The shapes inside these concave portions 38 correspond to the shapes of the fitting pieces 30a so that the fitting pieces 30a of the male body 20 mesh with each other.
That is, the concave ridge portion 38 has an open portion having substantially the same shape and the same size as the fitting piece 30a on the inner side. Band 36 and concave streak 38
Is integrally formed of an elastic synthetic resin material or the like. In this embodiment, the male body 20 and the female body 22 are formed of a synthetic resin material such as high-density polyethylene.

Further, a plurality of strip-shaped rib pieces 40 having a small thickness are provided on the inner peripheral surface of the concave streak portion 38 in parallel at intervals.
Is formed. These rib pieces 40 are made of a synthetic resin material that is more flexible than the synthetic resin material that forms the convex ridges 26 and the concave ridges 38. By these rib pieces 40,
The inner surface of the concave streak portion 38 and the fitting piece 30a are more closely adhered to each other. In this case, the plurality of rib pieces 40 play the role of a sealing material.

As shown in FIGS. 5A and 5C, the male body 20 and the female body 22 are heat-sealed at opposite longitudinal ends by, for example, a heat sealing method or a fusing sealing method. The male body 20 and the female body 22 are formed into a ring shape by being thermally fused by a method so as to face each other. Thus, the annular opening / closing tool 18 having the seal portions 42 on both sides thereof is formed. As the heat sealing method, for example, various heat sealing methods such as an impulse sealing method, an impulse fusing sealing method, a high frequency sealing method, and an ultrasonic sealing method can be appropriately used.

The opening / closing member 18 is fixed to the periphery of the opening 14 of the bag 12. That is, the opening / closing tool 18

For example, two valves 48a and 48b are provided. That is, for example, two valves 48a and 48b are formed at the other end in the longitudinal direction of the bag body 12 and at both ends in the width direction. The valves 48a and 48b are formed in a flat tubular shape with a plastic film, for example. The valves 48a and 48b are formed of a plastic film having a laminated structure in which an ethylene vinyl alcohol copolymer film, a polyethylene film, a polyamide film, a polyethylene film, and an ethylene vinyl alcohol copolymer film are sequentially laminated. These valves 48
a and 48 b are formed by the same manufacturing method as that of the bag body 12. Further, these valves 48a and 48b may be formed, for example, by laminating two strip-shaped laminated plastic films and heat-sealing or bonding both ends in the width direction.

The opening 50a of the valve 48a and the opening 50b of the valve 48b are

Is inserted into the outer valve portion 56a such that the other end of the member projects outside from the outer valve portion 56a.

Therefore, when the air inside the bag body 12 is sucked while the air bleeding member 90 is attached to the suction nozzle 120b of the vacuum cleaner 120, an escape path for the air is formed. Air outside the body 12 is ventilated. Therefore, if the air bleeding member 90 is used, the air in the bag body 12 can be continuously sucked for a long time without burdening the motor of the vacuum cleaner 120.

Next, an operation process for compressing and storing a futon using the compressed storage bag 10 will be described mainly with reference to FIGS.
This will be described with reference to FIGS.

First, in the compressed storage bag 10, FIG.
As shown in FIG. 1A, the futon 100 is connected to the opening 1 of the bag 12.
4 can be folded in. In this case, it is preferable that the futon 100 be dried in advance on the sun or put on a futon dryer. And the futon 100 is shown in FIG.
As shown in (B), it is moved to the valve 48a, 48b side,
The edges of the openings 14 are aligned. Further, the opening 14 of the bag 12 is sealed by fitting the male body 20 and the female body 22 of the opening / closing tool 18.

Next, the open hole 50b of the outer valve portion 56b of the one valve 48b is sandwiched by the stopper 60 and hermetically closed. That is, as shown in FIG. 9, the first locking member 62 and the second
Is arranged so that the end portion B of the outer valve portion 56b of the valve 48b is located between the locking member 64 and the locking member 64. Then, the outer valve portion 56b is closed so as to close the open end 74 of the first locking member 62.
The peripheral end of the open hole 50b is covered with the first locking member 62. Further, with the peripheral end of the open hole 50b of the outer valve portion 56b covered by the open end 74 of the first lock member 62, the second lock member 64 engages inside the pressing portions 78a, 78b. The first locking member 62 is fitted so that the wall surface is in close contact with the outer wall surfaces of the support portions 68a and 68b of the first locking member 62. In other words, the support portion 6 of the first locking member 62
8a, 68b and pressing portions 78a,
The opening hole 50b of the outer valve portion 56b is sandwiched between the opening hole 50b and the opening 78b.

In this case, since the inner wall surfaces of the pressing portions 78a, 78b are pressed against the outer wall surfaces of the supporting portions 68a, 68b by their elastic force, as shown in FIG. The support portions 68a, 68b of the 62 and the pressing portions 78a, 78b of the second locking member 64 are fitted in close contact. Therefore, the end B of the outer valve portion 56b near the opening 50b is firmly held between the support portions 68a, 68b and the pressing portions 78a, 78b, and the opening 50b can be securely sealed. .

Further, since the support portions 68a, 68b and the pressing portions 78a, 78b are formed in the shape of the cross section "C", when they are fitted, the support portions 68a, 68b and the pressing portions 78a, 78b are fitted. Can be dispersed. Therefore, the outer valve portion 5 sealed by the stopper 60 is provided.
In the vicinity of the open hole 50b of 6b, wrinkles hardly occur. Therefore, it is possible to prevent the air from being sucked in from the outside of the valve 48b, and even after storing the compressed material such as the futon,
The vacuum state in the bag body 12 can be maintained for a long time.

Then, the outer valve portion 56a of the other valve 48a
12C, the suction nozzle 120b of the household vacuum cleaner 120 is inserted as shown in FIGS. In this case, the suction nozzle 120b is previously provided with the air release member 90.
Is attached. The air bleeding member 90 is
When the suction nozzle 120b is inserted into the outer valve portion 56a to suck the air inside the bag body 12, the suction is performed so that the other end of the pipe main body 92 of the air release member 90 projects outside from the outer valve portion 56a. It is mounted on the nozzle 120b.

Then, the air in the bag body 12 is removed by the electric vacuum cleaner 1.
The inside of the bag body 12 is depressurized by suction at 20.
At this time, since the inner surfaces of the inner valve portion 58a of the valve 48a are in close contact with each other, the inside of the bag body 12 is sealed.

Thereafter, the suction nozzle 120b of the cleaner 120 is pulled out of the outer valve portion 56a of the valve 48a, and as shown in FIG. 12D, the wrinkles of the outer valve portion 56a of the valve 48a are extended in the direction of the arrow, and By sandwiching the end A of the outer valve portion 56a with the stopper 60, the opening 50a of the valve 48a can be completely sealed. Thus, the futon 100 put in the bag body 12 is compressed and stored.

In the compressed storage bag 10, the outer shape of the entire bag 12 becomes smaller as the decompression proceeds, and the bag 12
And the futon 100 stored in the bag body 12 is compressed. For this reason, it is possible to compactly store, for example, futons, blankets, thick clothing, and the like so as not to be bulky. Therefore, the storage space for the stored items can be small, and the storage space can be effectively utilized.

Further, in the compressed storage bag 10, since the air in the bag body 12 is sucked and depressurized by using the air release member 90, the load on the motor of the vacuum cleaner is reduced in a simple and relatively short time. In addition, it is possible to compress and store items such as futons. Therefore, in this compression storage bag 10, conventionally, the suction time was long, and it was not applied because the load on the motor of the vacuum cleaner was increased.
For example, the present invention can be applied to down products such as duvets and down jackets. Moreover, in the compressed storage bag 10, the intake of air from the outside of the bag body 12 can be prevented by the valves 48a and 48b. Therefore, the vacuum state in the bag body 12 can be maintained for a long time even after the compression storage.

The results of a performance test of the compressed storage bag when the duvet is compressed and stored, for example, using the compressed storage bag according to the present invention are shown below. In this case, as shown in FIG. 13, the compression storage bag used as the test material was a compression storage bag having only one valve and having a bag length of 140 cm and a width of 90 cm. That is, the compression storage bag 200 shown in FIG. 13 includes a flat rectangular bag body 202,
An opening 204 is provided at one longitudinal end of the bag 202. A valve 206 is provided at the other end in the width direction at the other end in the longitudinal direction of the bag body 202. The plastic film forming the bag body 202 and the valve 206 of the compression storage bag 200 is the same as that shown in the above-described embodiment, and the work process for compressing and storing the stored items is also the same. In addition, as storage items stored in the compression storage bag 200,
A down duvet of 100% cotton, 90% cotton down, and 10% small feather was used. Therefore, Table 1 shows experimental results obtained by examining the suction time and the storage compression ratio when the duvet is compressed and stored using the compression storage bag 200.

[0060]

[Table 1]

In this performance test, first, the duvet is folded in four and stored in the compression storage bag 200 shown in FIG.
In a state where the opening 208 was opened, a predetermined weight plate was used to measure the thickness of the duvet before compression (before the air in the bag body 202 was depressurized by suction). As shown in FIG. 13, the thickness of the duvet is measured by dividing the width of the duvet into two equal parts and four parts by dividing the vertical length of the duvet into two equal parts. Measurement points were used. Next, the air in the bag body 202 is sucked and decompressed from the opening 208 of the valve 206 of the compression storage bag 200 in which the duvet is stored, and after the duvet is compressed and stored, the measurement measured before compression is performed. The point thickness was measured again.

Further, Table 2 shows an experimental result obtained by examining a suction load test of the vacuum cleaner when the duvet is compressed and stored using the compression storage bag 200.

[0063]

[Table 2]

As shown in Tables 1 and 2, in the compressed storage bag 200 according to the present invention, the opening 208 of the valve 206 is provided.
The air inside the bag 202 is sucked to reduce the pressure inside the bag 202 to a vacuum state.
Then, the suction time can be shorter than that. Further, in the compressed storage bag 200, when the air in the bag body 202 is sucked and decompressed, the air vent member is used, so that no load is applied to the motor of the vacuum cleaner. For this reason, conventionally, it has become possible to easily and safely store a compressed product of a down product such as a duvet that requires a long suction time without imposing a load on the vacuum cleaner. Therefore, in the compression storage bag according to the present invention, down products such as down bedding such as down duvets and down clothing such as down jackets can be compactly stored and stored.

Further, in the compressed storage bag 10, the bag 1
Since the ultraviolet absorbent is contained in the high-density polyethylene film of the base material 16 located on the outer surface of the second 2, ultraviolet rays can be cut off. Therefore, in the compressed storage bag 10, deterioration of the base material 16, which is the material of the bag body 12, such as sunburn due to light, particularly, ultraviolet rays, can be prevented.
Can improve the sealing property and the weather resistance. Therefore, in the compressed storage bag 10, the sealed property can be maintained for a long time after the stored items are compressed and stored. Moreover, since the high-density polyethylene film of the base material 16 located on the inner surface of the bag body 12 is subjected to insect repellent, fungicide and deodorant treatments, the compressed storage bag 10 is compressed and stored in the bag body 12. It is possible to prevent insects, molds, and stench from being attached to the stored items such as the futon.

Table 3 shows the experimental results of examining the change over time in the storage compression ratio when the duvet is compressed and stored using the compression storage bag 200. In this performance test, FIG.
As shown in the figure, the thickness measurement points were divided into two parts that divide the width of the duvet into two equal parts and eight parts that divide the length of the duvet into three equal parts in the vertical direction.

[0067]

[Table 3]

In the compressed storage bag 200, since the deterioration of the bag body 202 due to light from the outside can be prevented, as shown in Table 3, the compression ratio is maintained even after a long time has passed after the stored items are compressed and stored. can do.

In the above-described embodiment, the two valves 48a and 48b are provided in the bag body 12, but only one valve may be provided. In the above-described embodiment, the air release member 90 has the hook 94 at one end thereof.
Although the whole is formed in a J-shape, the air release member 90 may be formed only of the pipe body 92, for example. In this case, the air release member 90 is attached to the side surface of the suction nozzle 120b with, for example, an adhesive tape and an adhesive. Thus, the suction nozzle 120 of the air release member 90
The means for attaching to b can be changed as appropriate. The air vent member 90 has a cross-sectional shape of, for example, a triangle, a quadrangle, or the like.
It may be formed in a polygonal rectangular tube shape such as.
