[Detailed description of the device]

[0001]

[Industrial applications]

 The invention is an intake valve for a deaeration packaging bag, which can store clothes, futon, etc. by shrinking and shrinking, and can also store food etc. for a long period of time, and clothes, futon, etc. using the same. Degassing packaging bag.

[0002]

[Prior Art]

 To store clothes, futons, etc., fold them as they are, store them in a clothing case, a futon bag, or other storage container and store them in a designated storage place. Since such items are bulky in volume, they required a large storage space.

Therefore, in view of the fact that these are textile products, after being stored in an airtight packaging bag, the inside of the packaging bag is degassed to a substantially vacuum state by a vacuum device or the like, and the entire packaging bag in the stored state is It has been proposed to reduce the volume. For example, a deaeration packaging bag such as a futon according to Japanese Utility Model Publication No. 57-88745, a sealed package according to Japanese Utility Model Publication No. 58-45255, and a deaeration method according to Japanese Utility Model Publication No. 3-11607. It is a pack system, and is a storage method and processing apparatus for storing textile products according to Japanese Patent Laid-Open No. 3-176335. In addition, after storing the futon, etc. in an airtight packaging bag, the opening is heat-welded and sealed with iron etc., and the nozzle of the vacuum cleaner is inserted into the slightly opened suction port to force it. After sucking in, there is one that seals the suction port again by heat welding and seals it tightly to a specified stopper.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned Japanese Utility Model Publication No. 58-45255, which has been conventionally proposed, a large vacuum device for complete airtight treatment and a welding seal device for hermetically sealing in a vacuum atmosphere are required. However, this could not be processed in ordinary households and required dedicated factory equipment.

In addition, after degassing as in Japanese Utility Model Laid-Open No. 57-88745, Japanese Utility Model Laid-Open No. 3-11607, Japanese Unexamined Patent Publication No. 3-176335, a method of heat-sealing an opening, a method of sealing a stopper, etc. The airtightly treated part of the packaging bag could not be completely sealed, and outside air sometimes entered after the airtightness and returned to its original shape. Not only that, even if the heat welding method and stopper sealing method can be easily performed in a general household using a vacuum cleaner, the degree of inferiority in the procedure of the operator is large, and as a result, However, degassing was extremely troublesome and it was extremely difficult to obtain the desired effect.

Further, when heat-sealing the sealed portions as a method for degassing at home, it is necessary to break the sealed portions when opening them after a lapse of a predetermined storage period. At the time of use, the packaging bag itself became smaller, and it was sometimes difficult to reuse it.

On the other hand, by vacuum-packing foods and the like, there is a similar problem when storing for a long period of time, so that the inside of the packaging bag can be easily degassed, and it can be surely performed. It was what was desired.

Therefore, the present invention has been devised in view of the above-mentioned various existing circumstances, and the air intake in the deaeration packaging bag used when the clothes, the futon, etc. are reduced and stored. We propose a valve that can maintain a sufficient sealing performance after degassing, and can easily and reliably perform sealing after degassing using a vacuum cleaner, etc. By maintaining the degassed state of the food, the reduced state can be maintained and the storage can be reliably performed.Furthermore, food can be stored for a long period of time, and it can be put in and out for storage. An airtight valve for the deaeration packaging bag that has a detachable hermetically sealed portion at the opening of the bag body to facilitate re-use while maintaining sufficient sealing performance after deaeration treatment. To provide deaeration packaging bags for clothing, futon, etc. With the goal.

[Action]

 In the deaeration packaging bag for clothes, futons, etc. according to the present invention, the hermetically sealing part 2 of the opening in the bag body 1 is opened so that a predetermined stored article C such as clothes, futon, etc. is placed in the bag body 1. The bag body 1 is stored and the forced engagement of the bag body 1 seals and seals the bag body 1.

In the intake valve 5, the suction operation after the tip of the suction nozzle N of the vacuum cleaner B is applied is for sucking the air in the bag body 1. At this time, the suction cylinder 9 is in the vicinity of the top. The opening / closing slit 10 formed in 1 is opened by sucking and tilting the top portion itself, and the air in the bag body 1 is sucked into the vacuum cleaner B.

After the suction operation of the vacuum cleaner B, as the inside of the bag body 1 is degassed, the inside of the bag body 1 becomes a negative pressure state and deflates, and the stored articles C are stored. The bag body 1 comes into close contact and compresses this C.

Further, the negative pressure state in the bag main body 1 automatically closes the opening / closing slit 10 of the intake valve 5, and the seal lid 11 forcibly fitted into the intake valve 5 is Stop the valve 5.

In the sealing lid 11 that is stoppered, the cylindrical insertion tube portion 14 is forced into the space between the inner circumference of the upper opening portion of the lid holding cylinder 8 and the outer circumference of the top portion of the intake cylinder 9. By fitting it in, the intake valve 5 as a whole is structurally strengthened, the distortion of the intake valve 5 itself due to external force, impact, etc. is prevented, and the airtightness of the intake valve 5 itself is secured.

The opening of the hermetically sealed portion 2 after an appropriate period of time allows the outside air to be introduced into the bag body 1 to restore the stored article C to be stored into the original shape and take it out.

[0019]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In the drawings, reference numeral 1 indicates a shape for accommodating and storing an article C to be stored, such as clothing, futon, and food. The formed bag body is the deaeration packaging bag itself (see FIG. 4) and is formed in a bag shape with one end opened by an airtight and flexible synthetic resin sheet material. The size of the bag body 1 itself corresponds to the size of the article C to be stored and packed. For example, if it is clothes or the like, it is formed to be relatively small, and if it is a futon or the like, it is large. It is formed. It goes without saying that the bag body 1 also contains, for example, vegetables, meat, and other foods that are stored for a long period of time in a package.

A hermetic seal portion 2 is formed in the opening of the bag body 1, and the hermetic seal portion 2 is formed in a doubled manner as shown in the figure. As shown in FIG. 2, the hermetically sealing portion 2 itself includes a seal ridge 3 protruding in a ridge shape along the left-right direction of the opening on one of the inner side surfaces of the opening of the bag body 1. Similarly, on the other hand, a seal groove 4 is formed in a groove shape along the left-right direction of the opening so as to be detachable from the seal projection 3. Further, each of the seal ridges 3 and the seal grooves 4 is formed on a ridge surface which is integrally formed on the formed fabric surface of the bag body 1 and is formed to be slightly hard. After they are aligned with the opening of the seal groove 4, they are pressed from the back side of each other to engage and integrate them, and the opening itself is separated by force. By doing so, the engagement of the both 3 and 4 is released, and they can be released.

The seal ridges 3 and the seal grooves 4 shown in the drawings have a dovetail-shaped cross section, but are not limited to this, and may be circular or C-shaped, for example. The cross-sectional shape is not particularly limited as long as the inside and the outside of the bag body 1 can be airtightly closed by coupling the both 3 and 4.

The double-sealed hermetic seal portion 2 makes it possible to more reliably block the inside and outside of the bag body 1 and not only prevent the outside air from entering the bag body 1 after the deaeration process, for example. The outside air is not sucked into the bag body 1 through the opening of the bag body 1 even during the deaeration process via the intake valve 5 described later.

Further, the bag body 1 is provided with an intake valve 5 that sucks the air in the bag body 1 and then stops and seals the air after the suction. As shown in the figure, the intake valve 5 is mounted and fixed to a mounting opening 6 formed in the bag body 1, and is made of a synthetic resin that is slightly harder than the material forming the bag body 1. .. That is, in the mounting plate 7 fixed to the inner peripheral edge of the mounting opening 6, there is a bottomed cylindrical lid pressing cylinder 8 having a large diameter that is recessed inward of the bag body 1 and is located outside, and the lid pressing cylinder 8 A small-diameter bottomed cylindrical intake cylinder 9 located inside and protruding from the bottom of the bag main body 1 is arranged inside and outside in a double cylinder shape, and there is a ceiling near the upper part of the intake cylinder 9 The opening / closing slit 10 is formed in a cut shape substantially along the transverse direction. Then, the seal lid 11 is forcibly fitted between the lid pressing cylinder 8 and the intake cylinder 9 to firmly seal the closed opening / closing slit 10 of the intake cylinder 9 after suction. It has become.

The mounting board 7 itself holds the shape of the intake valve 5 as a whole, and changes in shape of the bag body 1 and the stored articles C and the like, the suction operation of the suction nozzle N in the vacuum cleaner B described later, and the like. Is designed so that it is not easily distorted. If necessary, the suction nozzle N is formed into a disk shape which is slightly larger than the diameter of the suction nozzle N so that smooth suction work can be performed without distortion even during suction operation (Fig. 3).

The lid pressing cylinder 8 and the intake cylinder 9 are both deformed to a flat shape due to the forced pressing force from the outside of the lid pressing cylinder 8, and are soft elastic enough to open the opening / closing slit 10 above the intake cylinder 9. Is equipped with. Further, as shown in FIG. 3, during suction operation by the suction nozzle N, the top portion of the intake cylinder 9 is sucked, so that only this top portion is inclined toward the vacuum cleaner B side and the opening / closing slit 10 is opened. It is open. In this case, although not shown, the intake cylinder 9 itself has a substantially U-shape in a plane, and the opening / closing slit 10 may be located in the U-shape.

A predetermined gap is set between the inner periphery of the upper opening portion of the lid pressing cylinder 8 and the outer periphery of the top portion of the intake cylinder 9, and the seal lid 11 is forcibly fitted into this void portion. It is like this. That is, the seal lid 11 is integrally connected to the mounting board 7 via, for example, a strip-shaped connecting piece 12, and as shown in FIG. A relatively large disk-shaped cover 13 and an insertion cylinder 14 that is forcibly fitted into the space between the inner circumference of the upper opening of the lid pressing cylinder 8 and the outer circumference of the top of the intake cylinder 9. Consists of. It is extremely desirable that the inner peripheral surface of the insertion tube portion 14 is in close contact with the opening / closing slit 10 partial opening in order to maintain the airtightness after suction. It is formed so that it closely adheres to the surface.

Next, to explain an example of use of this, by opening and closing the hermetic seal part 2 of the opening in the bag body 1, the opening itself is opened, and clothes, futon, food A predetermined to-be-stored article C such as a product is stored, and the hermetically sealing portion 2 is tightly sealed and sealed by the forced engagement between the seal ridges 3 and the seal grooves 4 (see FIG. 4).

Next, the tip of the suction nozzle N of the vacuum cleaner B is applied to the intake valve 5, and the air in the bag body 1 is sucked through the intake valve 5 by the operation of the vacuum cleaner B (see FIG. 3). Then, in the intake valve 5, the opening / closing slit 10 formed in the vicinity of the top of the intake cylinder 9 is opened by sucking and tilting the top itself, and the air inside the bag body 1 is inside the vacuum cleaner B. As a result, the inside of the bag body 1 is deaerated. Along with this, the inside of the bag body 1 is deflated due to a negative pressure state, the bag body 1 is brought into close contact with the stored articles C to be compressed, and the volume C is appropriately reduced. It is assumed that

After that, when the operation of the vacuum cleaner B is stopped, the opening / closing slit 10 in the intake valve 5 is half automatically closed due to the negative pressure inside the bag body 1. Therefore, the seal lid 11 is forcibly fitted into the intake valve 5 to firmly stop the intake valve 5, and it may be stored in a predetermined place in this state (see FIG. 2).

[0030]

[Effect of the device]

 The present invention is configured as described above, and therefore, after degassing after storing articles C to be stored, such as clothing, futon, and food, the opening of the bag body 1 is closed by the sealing seal 2. The airtightness can be sufficiently maintained, and the bag body 1 can be opened by opening it to facilitate reuse, and the air intake valve 5 can be reliably sealed after the deaeration process by the vacuum cleaner B or the like. It can be processed, and by keeping the inside of the bag body 1 substantially vacuum for a long period of time, the reduced state can be maintained, and various stored articles C can be reliably reduced and stored for a long period of time. Can be stored.

That is, this is because the intake valve 5 in the present invention is fixed to the inner peripheral edge of the mounting opening 6 formed in the bag body 1 which is the deaeration packaging bag itself formed of the airtight sheet material. A lid holding cylinder 8 having a large diameter and having a bottom, which is recessed inward of the bag body 1 on the mounting board 7, and has a bottom, and which projects from the bottom of the lid holding cylinder 8 to the outside of the bag body 1. In addition, a small-diameter bottomed cylindrical intake cylinder 9 located inside is arranged in a double cylinder inside and outside, and in the vicinity of the upper part of the intake cylinder 9 where the top is located, the intake cylinder 9 is almost crossed. This is because the slits 10 are formed in a cut shape so that clothes, futons, etc. can be reduced in size and stored in the bag body 1, and foods, etc. can be vacuum-packed in a fresh state. It can be stored in a state for a long time.

Moreover, when the suction nozzle N tip of the vacuum cleaner B is applied to the intake valve 5 and the suction operation is performed, the opening / closing slit 10 formed near the top of the intake cylinder 9 has the top itself. Is sucked and tilted to be opened, and the air in the bag body 1 is exhausted and sucked by this suction operation. Therefore, unlike the conventional case, a special configuration of the suction port is not required, which is troublesome. There is nothing. Not only that, since it is only necessary to apply the tip of the suction nozzle N, deaeration work is easy, and if the negative pressure state in the bag body 1 can be realized, the opening / closing slit 10 will be half closed automatically. Therefore, the degassed state in the bag body 1 is maintained at the end of the suction work, and the air that is inevitably generated when the suction nozzle N is inserted into or removed from the bag body 1 as in the conventional case. It does not enter the bag body 1.

Further, when the seal lid 11 is plugged into the intake valve 5 after the deaeration process, the tubular insertion tube portion 14 causes the inner circumference of the upper opening portion of the lid holding cylinder 8 and the outer circumference of the top portion of the intake cylinder 9 to overlap with each other. The intake valve 5 is forcibly fitted into the space between them to structurally reinforce the intake valve 5 and prevent the intake valve 5 itself from being distorted by external impact, external force, or the like. As a result, the open / close slit 10 in the intake valve 5 is not opened unexpectedly, and the open / close slit 10 in the closed intake cylinder 9 after suction is sealed by the insertion cylinder portion 14, and the intake valve 5 itself. The airtightness of the bag body 1 is ensured, and the degassed state in the bag body 1 is maintained satisfactorily for an extremely long period of time.

Further, as the inside of the bag body 1 is deaerated by the suction operation of the vacuum cleaner B, the inside of the bag body 1 is in a negative pressure state, the bag body 1 is deflated, and the stored articles C are stored. Since the bag body 1 comes into close contact with and compresses this C, for example, in the case of clothes, futons, etc., the volume thereof becomes extremely small, which is about one third to one fourth of the original shape. It is convenient to handle and easy to store and store.

Further, since the opening / closing portion of the bag main body 1 is provided with the detachable sealing seal portion 2, by tightly sealing the sealing seal portion 2, it is possible to prevent external air leakage while the intake valve 5 is inhaling. It is possible to smoothly perform the intake operation without letting air enter the bag body 1.

Further, when the appropriate storage period ends and the stored articles C to be stored are taken out, the hermetically sealing portion 2 may be opened, and by opening the air, the outside air is released into the bag body 1. Since the stored article C is restored to its original shape by introducing it, the bag body 1 itself is not damaged or cut after being taken out, so that the bag can be reused in exactly the same manner, which is a waste. There is no such thing.
