Description

Degassing Bags {DEAIRING BAG}

Degassing pouches with a degassing passage attached to a pouch body made of a flexible synthetic resin sheet for the purpose of compactly storing clothes or bedclothes or maintaining food freshness have conventionally existed.

The method of using this degassing bag is briefly described. The clothes and the like are stored inside the degassing bag, and then the zippers of the entrances and exits of the object are closed, and the nozzle of the vacuum cleaner is attached to the isolating valve to suck the air. . Since the shutoff valve has a check function, the outside air can be kept in the deaeration state without having to enter the inside of the deaeration bag again. The contents such as clothes and bedclothes are put in a degassing bag to remove the air inside the bag, so that the air contained in the contents is also discharged out of the bag, thereby reducing the volume. Thus, it is possible to accommodate compactly by the reduced volume.

In the case of storing the food, it can be packaged in a compact manner by discharging the air inside the degassing bag to the outside in the same manner as described above, and can prevent the food from coming in contact with the air and causing injury.

There are various types of shut-off valves of this kind. However, in the type of suctioning by attaching a nozzle of an electric vacuum cleaner such as a futon storage bag to a shut-off valve, it is generally formed of a synthetic resin having rigidity, and the tip of the nozzle The valve is opened by pressing the shut-off valve tightly to allow suction, and the valve is closed when the nozzle is released.

This type of shut-off valve is a molded product that has strong shut-off capability but is rigid. Therefore, when the unused deaeration bag is folded and stored, only a part of the shut-off valve interferes, or a hard shut-off valve There is a problem that the adhesion of the synthetic resin sheet of the flexible bag body is easy to be separated or made. In addition, even after the contents are degassed, a part of the shutoff valve protrudes to the outside, so that a part of the protruding shutoff valve interferes, especially when the bag is stacked, and if something touches the shutoff valve, The valve could open, causing air to enter the pocket.

In addition, a shutoff valve exists in which an opening is formed in a flat cylindrical body made of a film made of a soft synthetic resin, a zipper or a curved passage is formed inside the cylindrical body, and is attached to the outside of the degassing bag. In addition, since the shutoff valve protrudes outside the degassing bag, it may interfere, or the part of the shutoff valve may be cut off and fall off by hitting the shutoff valve part.

However, the present invention does not impair the compactness of the degassing bag regardless of before and after use, and in addition, the degassing bag which is hard to fall off the adhesion between the air passage for degassing and the bag body, and can maintain the degassing property. It is a problem to provide.

This invention relates to the improvement of the degassing bag used for compressing garments, Futons, etc. compactly and maintaining freshness of a food.

Next, an example of the degassing bag which concerns on embodiment of this invention is demonstrated. In addition, in this description, the direction on the opposite side to the accommodating entrance part 2 side of the degassing bag 1 is made downward.

1 is a plan view of the degassing bag 1 of the present example. The degassing bag 1 is a planar rectangular bag formed by at least two sheets of non-breathable sheets 11 and 12 made of resin and the like. The storage entry part 2 is provided on the upper side 13 of the short side. The bottom side 14 and the side sides 15 and 16 are closed.

The surface side seat 11 is provided with a degassing shutoff valve 4 inside the bag.

On the other hand, arbitrary letters and patterns, such as a brand name and a handling instruction, may be printed on the surface of the sheets 11 and 12, and antibacterial and deodorizing processing may be given to the sheets 11 and 12 itself. Moreover, about the size of the degassing bag 1, you may determine arbitrarily according to objects, such as a garment, a blanket, a futon, and the like. The shutoff valve 4 may be provided at any position of the degassing bag 1.

The use method of this degassing bag 1 is demonstrated. First, the zipper 3 of the thing entrance / exit part 2 is made into the open state. Then, the stored items such as clothes are stored in the degassing bag 1 from the stored object inlet and out part 2 in the open state, and the zipper 3 is closed. Thereafter, the deaeration bag 1 is rolled up by hand to compress it, or by inserting a vacuum cleaner nozzle or the like into the opening 43g of the shut-off valve 4 and degassing, the deaeration bag 4 1) By discharging the air inside to the outside, the degassing state inside the degassing bag 1 is completed.

The zipper 3 provided as a closing means of the thing entrance-and-receiving part 2 is a fitting type in this example, and as shown to part (A) of FIG. 2, the convex part 31 in one inside of a sheet | seat, The recessed part 32 is formed in the opposite side.

Engaging parts 33 and 34 are formed in the convex part 31 and the concave part 32, respectively, and the concave part 32 is an airtight convex part 36 and an airtight part in the convex part 31. The holding recess 37 is formed. The convex jaw portion 31 is formed such that the two convex pieces 31a and 31a are opposed to each other with the concave portion 37 for hermetic holding therebetween. Each is formed with the convex part 36 for hermetic holding in between.

Further, the width t35 of the passage portion 35 of the recess 32a is smaller than the width t33 of the locking portion 33. When the zipper 3 is closed, when the convex jaw 31 and the concave jaw 32 are pressed, the catch 33 passes through the passage 35 so as to open, and the catch of the concave jaw 32 is passed. Meshes with (34). The interlocked state is shown in part (B) of FIG. 2, and there is almost no gap between the jaws 38, and furthermore, it becomes a labyrinth, so that the inside airtight is maintained without invading air from the outside. The degassing bag 1 can be closed.

In addition, the zipper 3 is not limited to the shape as shown in FIG. 2, A various thing can be employ | adopted.

In addition, a slider made of resin or the like may be provided on the outside of the bag of the zipper 3 so as to facilitate the closure of the zipper 3.

As shown in Fig. 3, the shutoff valve 4 is provided with a flap 42 inside the substantially cylindrical air passage 41 having a flat cross section.

The outer part of the shut-off valve 4 of this example consists of two rectangular exterior seats 43a and 43b which oppose, and only one short side side of these exterior seats 43a and 43b is opened, and the inner opening 43c is opened. Is formed, and the remaining three circumferential circumferences 43d, 43e, 43f are bonded by a method such as thermocompression bonding. In addition, an outer opening 43g is formed in the vicinity of the short side closing portion 43d of the exterior sheet 43a, and is bonded to the inner surface of the surface-side sheet 11 on which the elliptical opening 11a is formed. It is supposed to be. As a result, a substantially cylindrical air passage 41 having a flat cross section is formed, which extends from the opening 11a formed on the inner surface of the surface side seat 11 of the bag to the inner opening 43c of the shutoff valve 4. It is. Here, the shape of the opening part 11a is not limited to an ellipse, It can change into various shapes, For example, suppose it has the handle part 11b as shown in FIG. The opening of the opening part 11a may be made easy by pulling up the handle part 11b. In addition, although the shape of the opening part 11a of the deaeration bag 1 and the outer opening part 43g of the shutoff valve 4 is substantially identical in FIG. 3, it is not limited to this, The outer opening part 43g is made into the opening part ( It may be formed larger than 11a, or the exterior sheet 43a itself of the portion corresponding to the opening 11a may be omitted (not shown). In addition, the handle part 11b is not limited to being provided in the opening part 11a of the deaeration bag 1 as mentioned above, but may be provided in the outer opening part 43g of the shutoff valve 4, and various It can be changed.

On the other hand, the exterior sheet 43a and the surface side sheet 11 are at least around the opening portion of the outer opening 43g (opening portion 11a), as shown in FIG. 3, in order to prevent inversion of the air passage 41. 43j and the right side (pouch inner side), preferably the right end 43k of the air path 41 need to be adhere | attached.

In addition, you may abbreviate | omit the exterior sheet 43a of the side adhere | attached on the inner side surface of the surface side sheet 11, and may form an air path by attaching the exterior sheet 43b directly to the surface side sheet 11. As shown in FIG.

Moreover, as another example of the form of the shutoff valve 4, the inner side opening 43c and the outer side opening 43g are formed by opening both sides of the short side of the exterior seat | sheet 43a, 43b, and the periphery 43e, 43f. ) Is bonded by a method such as thermocompression bonding to form an almost cylindrical air passage 41 having a flat cross section from the outer opening 43g to the inner opening 43c. As shown in FIG. 5, in this type of shutoff valve 4, the inner opening 43c is positioned inside the degassing bag 1, and the outer opening 43g is disposed with respect to the sides around the degassing bag 1. It is attached so that it is located outside.

Returning to the shutoff valve 4 of this example and continuing description, on the surface 43h of the air passage side of the exterior seat 43b, the other side is closed from one closure part 43e along the exterior seat 43b. The rectangular flap 42 is affixed over the part 43f, The center of the short side of the flap 42 continues from one end of the flap 42 to the other end, and is thermocompression-bonded with respect to the exterior sheet 43b. It is a sheet which consists of the fixing part 42a adhere | attached by the method of this etc., and the flap parts 42b and 42c which move to both sides centering on the fixing part 42a, and this flap part 42b and 42c is an air container. The air passage 41 is pushed against the surface 43i of the air passage side of the exterior sheet 43a on the side where the flap 42 is not attached by the airflow trying to exit the inside of the furnace 41. Block it.

On the other hand, one of the flap portions 42b of the flap portions 42b, 42c blocks the flow of air from the outside of the bag to the inside, and the other flap portion 42c prevents the flow of air from the inside of the bag to the outside. It works to block. That is, since the flap portions 42b and 42c are combined with each other to function in both directions of the air passage 41, it is also possible to use a method of maintaining the degassing state of the air inside the bag. It is also possible to use a method of charging and maintaining the state.

Therefore, after putting clothes or food into the degassing bag 1 and injecting a gas having a sterilization and sterilization effect through the shutoff valve 4 into the bag, the gas is degassed from the shutoff valve 4. The method is also possible and can be easily done without opening sterilization and degassing in one bag.

In the present example, the flaps 42 are arranged in two rows in parallel with each other so as to be perpendicular to the axis of the air passage 41.

The material of the exterior sheets 43a and 43b and the flap 42 is a soft synthetic resin film in this example, and the flap parts 42b and 42c of the flap 42 are on the air passage side of the exterior sheet 43a flexibly. It may be in close contact with the surface 43i. Therefore, a gap does not arise between the flap 42 and the exterior sheet 43a, and the airtight state inside a bag is maintained favorable.

In addition, the flap 42 is not limited to the shape described so far, but can be changed and implemented in various ways. For example, the flap 42 which provided the flap part only in the one side of the fixing part 42a is 1 piece. It may be set as a set so that it may oppose or oppose, respectively, and may arrange | position individually or in parallel also about the arrangement | positioning number of the flaps 42 in the air path 41. As shown in FIG.

Since the flap portions 42b and 42c are attached to both sides of the air passage 41 around the fixed portion 42a, the air passage 41 is usually shown in part (B) of FIG. 3. Is blocked for both directions. Therefore, in order to make the air passage 41 ventilate, the rod-shaped body 5 is connected to the inner opening 43c and the outer opening 43g of the air passage 41, as shown in FIG. This is done by penetrating through and releasing close contact between a part of the flap portions 42b and 42c and the surface 43i on the air passage side of the exterior sheet. As a result, the air passage 41 is allowed to be ventilated. Then, the air passage 41 returns to the blocked state by pulling out the rod-shaped body 5.

Although the rod-shaped body 5 is optimally performed as a suction nozzle for a vacuum cleaner, or a small pump incorporating a motor or a fan, it is a hollow straw type and may be degassed by an attractive force. Moreover, you may implement as a clogged rod body.

When the above-mentioned preferred embodiment of the air passage 41 and the shutoff valve 4 is put together, the substantially cylindrical shape which has a flat cross section by making the closed part 43e, 43f which both sides of the opposing exterior seat | sheet 43a, 43b close is closed. An air passage 41 is formed, and openings 43c and 43g are formed at both ends of the cylindrical air passage 41, and a flap 42 is provided in the valve. A first flap portion 42b and a second flap portion 42c movable around the fixing portion 42a, and having a fixing portion 42a attached to the outer sheet 43b. The flap portion 42b is in close contact with the surface 43i of the air passage side of the other exterior sheet 43a, thereby blocking the flow of air from one end side to the other end side of the air passage 41, Further, the second flap portion 42c is brought into close contact with the surface 43i on the air passage side of the other exterior sheet 43a, so that the second flap portion 42c is on the other end side of the air passage 41. That to block the flow of air toward the stage is to be understood as a shut-off valve according to claim.

In the shutoff valve, one of the facing seats 43a and 43b may serve as the seat 11 constituting the sealable bag 1.

The shut-off valve 4 attached to the degassing bag of this invention is not limited to what was demonstrated so far, A various change other than that is possible. For example, as shown in FIG. 6, of the two flaps 42 coordinated in parallel in the air passage 41, the front flap 42X located in the side of the outer opening 43g is an inner opening. It is assumed that the flap portion 42c is provided only on the 43c side, and the inner flap 42Y positioned on the side of the inner opening 43c has flaps on both sides of the inner opening 43c and the outer opening 43g. 42b and 42c may be provided.

Incidentally, in the present embodiment, the dimension L1 of the flap portion 42c in the direction along the air passage in the front flap 42X is 35 mm, and the flap in the same direction in the inner flap 42Y. The dimension L2 of the part 42b is 3 mm, and the dimension L3 of the flap part 42c is 16 mm. On the other hand, the width dimension L4 of the air passage 41 is 30 mm.

In the inner flap 42Y, the dimension L2 of the flap portion 42b is formed smaller than the dimension L3 of the flap portion 42c, but this causes the rod-shaped body 5 to be separated from the outer opening 43d. When inserted into the air passage 41, the flap 42b in the positional relationship facing the insertion direction of the rod-shaped body 5 is reversed in the reverse direction, to prevent the flap 42 from functioning. For that.

In addition, the dimension of each part shown above is an example of implementation, The position and dimension which install the flap 42 are not limited to this, It can change and implement in various ways.

In addition, as shown in FIG. 7, without providing the flap 42, only the cylindrical air passage 41 having a flat cross section formed by the two sheets 43a and 43b facing each other may be provided. . In this case, by opposing the two sheets 43a and 43b, it is possible to prevent outside air from invading the inside. In addition, the air in the bag can be discharged by inserting the rod-like body into the air passage 41 as described above.

In addition, as shown in FIG. 8, the flap 42b formed only in the direction toward the outside of the bag 42a and the bag with respect to the flap 42 attached to the exterior sheet 43b in the air passage 41. ), And may be a valve having a structure that blocks the flow of air from the outside of the bag to the inside.

In addition, the degassing bag with a valve of another system is further provided with a shut-off valve 4 according to the present invention, and for example, one valve is degassed by a vacuum cleaner, and the other valve is damaged. Both valves may be used together, or either valve may be selected and used to degas. This can be quickly degassed by, for example, applying to a large degassing bag.

In FIG. 9, the degassing bag 1 which attached another valve and the shutoff valve 4 which concerns on this invention is shown as an example. In addition, the hatching part in the figure has shown the part to which the sheet | seat was adhere | attached.

The flap sheet 61 is fitted to the front side sheet 11 and the back side sheet 12 of the degassing bag 1, and two sheets are stacked side by side in the section extending from the left side 15 to the right side 16 for a long time. It is a planar strip | belt-shaped sheet | seat which becomes. With respect to the flap sheet 61, air passages 62 partitioned by the adhesion of the sheets 11, 12 and 61 are formed.

In the part where this air passage 62 is formed, the upper end of the flap sheet 61 is adhere | attached on the horizontal line with respect to the sheets 11 and 12 (the flap sheets 61 are not adhere | attached), A degassing valve upper end portion 61a is formed. In addition, the flap seat 61 is adhere | attached on the line in a vertical direction with respect to the left-right part which fits the deaeration valve upper end part 61a, and the deaeration valve side part 61b is formed. The part surrounded by these three adhesive parts becomes the air path 62. On the other hand, in addition to this portion, the other upper end portions 61c of the flap sheet 61 are in a state where all of the sheets 11, 12, 61 are bonded to each other and completely closed, whereby the air flow at the time of degassing Only furnace 62 will flow.

The degassing mechanism 7 is the part which cut | disconnected the adhesion of the front side sheet 11 and the back side sheet 12 on the bottom side 14, and the airflow from the deaeration valve 6 passes through here, and a bag | bag is carried out. Flows out.

On the other hand, in the example shown in part (A) of FIG. 9, although the deaeration valve 6 is formed in two places on the left and right, and the deaeration unit 7 is formed in the center 1 place, these installation numbers are limited to this. It can be installed in moderation.

The cross section in the up-down direction of the degassing valve 6 is shown by the part (B), (C) of FIG. In the direction D from the inside of the degassing bag 1, since the flap sheet 61 comrades widens with air flow, the air path 62 opens and air flows. On the contrary, in the direction E from the outside to the inside, air to be introduced into the bag is stopped at the dead end portion 63, whereby the flap sheets 61 are brought into close contact with each other so that the air passage 62 is closed and the air is closed. Does not flow. Therefore, since only one direction of airflow is allowed, the state in which the air in the deaeration bag 1 is removed can be maintained.

When the degassing bag 1 is actually used, after storing the storage items such as clothes therein, degassing the degassing bag 6 through the degassing device 7 by pressing the degassing bag 1 with a hand or the like. . In addition, if necessary, the shutoff valve 4 can also be degassed by using a vacuum cleaner, and the degassing work can be efficiently performed.

In addition, the structure of the valve illustrated here is only one example, The shutoff valve also has a valve | bulb bag which has a valve of various other structures, such as the valve which consists of one flap seat 61, and the separate check valve. 4) it is possible to attach.

In addition, the structure of the valve illustrated here is only one example, The valve which consists of one flap seat 61, a separate check valve, and the surface of the deaeration bag 1 as shown in FIG. The valve seat 81 and 82 are formed in flat substantially cylindrical shape between the side seat 11 and the back side seat 12, and the flap 83 of the structure as shown in FIG. 8 is provided inside the valve ( 8) It is possible to attach the shutoff valve 4 also to a deaeration bag having a valve of various other structures.

Since this invention is comprised and used as mentioned above, it has the following useful effects.
