具を閉じる、というのが一般的である。BACKGROUND ART In recent years, a bag (chuck bag) that can be opened and closed by providing a band-shaped interlocking device (fitting device) composed of a male member and a female member at the opening portion of the bag has been developed. It has come to be used mainly in the food field. And recently, it is also used as a futon bag and a clothing bag. Such a bag with an occluding device for a futon bag or a clothing bag is characterized in that the occluding device is of a hermetically sealed type so that it can be deaerated to reduce its volume. As a degassing method, it is general that a part of the articulation tool is opened, weight is applied or a vacuum cleaner is used to degas the articulation tool, and then the articulation tool is quickly closed.

付き袋を提供することを目的とする。With such a closing method, it is sufficient if the articulation device can be quickly closed immediately after deaeration, but in reality,
It takes some time from immediately after degassing to closing the articulation device, and air re-enters during that time, so that there is a problem that a sufficient degassing state cannot be obtained. In addition,
Although it is possible to use various commercially available check valves, it is not a simple method because it takes time to attach the check valve to the bag and causes high cost. Therefore, an object of the present invention is to provide a bag with an articulating device that can maintain a degassed state immediately after degassing and has a simple structure.

On the other hand, after the degassing without applying pressure to the bag, the films in the degassing passage are in close contact with each other because the inside is in a depressurized state due to the expanding force of the contents. As a result, it is possible to maintain the deaerated state in the bag immediately after the deaeration passage is closed and deaerated. That is, the deaeration passage according to the present invention has a check valve-like action that allows only one-way air flow from inside the bag to outside the bag.

ルム15の内側に融着されている。As shown in FIG. 2, a coating film 19 is formed by applying an adhesive substance 18 in the deaeration passage 13 near the deaeration passage opening 13A, for example. Specific examples of the adhesive substance 18 include, for example, polybutene [kinematic viscosity 8 × 10 −4 m 2
/ s (100 ° C.)], but glycerin, edible oil, mineral oil, etc. may be used in addition to silicone oil. The adhesive substance 18 can be applied to the bag 11 in which the fusion-bonded portion 17 is formed, for example. As shown in FIGS. 4 and 5, the engaging device 21 is composed of one male member 22 and the other female member 23, and the male member 22 is provided inside the one upper film 15 which constitutes the bag body 12. By fusion, the female member 23 is fused inside the other lower film 15.

具21の材質は、例えばＬ−ＬＤＰＥである。The male member 22 is integrally formed with a belt-shaped continuous base portion (tape portion) 24 serving as a fusion-bonding portion, a head portion 25 having a heart-shaped cross section, and a connecting portion 26 having a rod-shaped cross section for connecting the two 24, 25. ing. In addition, the female member 23 is a base portion (tape portion) 27 which is a band-shaped continuous portion and serves as a fusion bonding portion, an arc-shaped first hook portion 28 formed on the base portion 27, and the first hook portion 28 facing each other. Thus, the arc-shaped second hook portion 29 formed on the base portion 27 is integrally formed. Edge 28 of both hooks 28,29
A gap 31 having a width substantially corresponding to the thickness of the connecting portion 26 is provided between A and 29A. Further, in this articulation tool 21, when the articulation tool 21 is closed, a surface contact state between the male member 22 and the female member 23 can be obtained, so that good airtightness can be obtained. The material of this bite 21 is, for example, L-LDPE.

る。The method of using the bag 11 with the engaging device is as follows. That is, the articulation tool 21 is opened, the contents 32 such as a futon are put in the bag 11, and then the articulation tool 21 is closed. As shown in FIG. 2, in this state, the deaeration passage 13 is closed. Next, as shown in FIG. 3, when the bag 11 is compressed by hand or the like, the internal pressure of the bag 11 increases, so that the coating film in the degassing passage 13 is increased.
A degassing hole 33 is formed at 19. As a result, the deaeration passage 13 is opened, and the air inside passes through the deaeration passage 13 and goes out of the bag 11.

気状態をそのまま維持される。When the bag 11 is decompressed sufficiently and then the compression of the bag 11 is stopped, the degassing holes 33 disappear immediately and the original coating film 19 is formed again. Then, due to the expansive force of the contents 32, a negative pressure is increased inside and a depressurized state is achieved. As a result,
Two films 15 above and below the degassing passage 13 through the coating film 19
A strong close contact between the two is obtained, and the bag is
11 Inflow of air from the outside to the inside through the deaeration passage 13 is blocked. As a result, the deaerated state in the bag 11 immediately after deaeration is maintained as it is.

侵入して脱気が不充分になる虞れはない。According to the bag 11 with an engaging device according to this embodiment,
Since the degassing passage 13 is provided in the bag body 12 and the coating film 19 of the adhesive substance 18 such as polybutene is formed in the degassing passage 13, air is degassed from the degassing passage 13 during deaeration. 11 Can be easily released to the outside. On the other hand, immediately after deaeration, the deaeration passage 13 is closed quickly and reliably, and the negative pressure inside the expansion of the contents 32 and the close contact state of the deaeration passage 13 through the coating film 19 cooperate with each other. As a result, the degassed state in the bag 11 immediately after degassing can be maintained as it is for a long time. Therefore, as compared with the conventional art in which the articulation device is partially opened and closed immediately after suction or deaeration so as to create a sealed state, air is re-opened before the bag is closed. There is no risk of degassing being incomplete by entering the bag.

Further, the deaeration work of the bag 11 can be performed while the articulation tool 21 is closed, and the opening / closing operation of the articulation tool as in the past is not necessary, so the work is simple.

At the approximate center between 46, the bottom side opening 43 of the intermediate film 44 is formed.
Third part for fixing a part of the vicinity to the lower resin film 15
The fused portion 47 is formed. When the width between the second fusion bonding portions 46 is wide, the fusion bonding portions 47 are configured such that the upper and lower resin films 15 are quickly brought into close contact with each other after the deaeration is completed. If the width between the fused portions 46 is narrow, it is not always necessary to form them. Then, as also shown in FIG. 11, a coating film 19 of an adhesive substance 18 such as polybutene is formed in these deaeration passages 42A, 42B, 42C ....

If a film such as LDPE or PP grade having adhesiveness is used, and if sufficient adhesion between the films can be obtained by this, the adhesive substance does not necessarily have to be applied. Further, in the above embodiment, the deaeration passage is provided in the bag body itself, but a tubular film for the deaeration passage may be provided so as to be connected to the bag body. This makes it easier to suck the air in the bag using a vacuum cleaner or the like.

単である。EFFECTS OF THE INVENTION According to the bag with an engaging device according to the present invention, since the deaeration passage is provided, deaeration during deaeration and sealing immediately after deaeration can be performed easily and reliably, Moreover, the degassed state after degassing can be maintained for a long time. Moreover, since the structure is simple, the implementation is easy. Further, when degassing the bag, the work of opening and closing the articulating device is not required, so the work is simple.
