Description

  The present invention is a valve for degassing operation in a bag. More specifically, in order to reduce the volume of a futon compression bag or a garbage bag, the bag is used by using a suction device such as a general household vacuum cleaner or a manual pump. The present invention relates to a valve that is attached to the inside of a bag and used for a degassing operation in the bag.

  In order to reduce the bulk at the time of storage, after putting a futon or clothes in a compression bag which can be sealed, the compression bag is sealed and the air in the bag is vented. This deaeration operation is performed by inserting the tip of the hose of a suction device such as a vacuum cleaner into the bag. Moreover, in order to reduce the bulk of the garbage bag put out to a garbage collection place, the inside of a bag may be deaerated.

  For example, when degassing the futon compression bag 23, generally, after the futon 24 is stored, the futon compression bag 23 itself is once sealed through a sealing means such as a fastener 25 provided in the futon compression bag 23 itself. Then, a part of the fastener 25 is opened, the tip of the hose 21 of the electric vacuum cleaner 22 is inserted, the vacuum cleaner 22 is turned on, the inside of the bag 23 is evacuated, and the fastener 25 is closed after degassing (see FIG. 8). ).

  In the case of this method, air may enter the bag 23 while the hose 21 is pulled out and the fastener 25 is closed after degassing. Further, during the deaeration operation, the futon 24 in the bag 23 may be sucked into the suction port of the hose 21 to block the suction port.

  Further, when degassing a bag such as a trash bag that does not have a special sealing means such as the fastener 25, the hose 21 is inserted by squeezing the opening, and the opening is converged immediately after degassing. However, there is a possibility that air may get in between, and the problem that the stored item closes the suction port of the hose 21 occurs as in the case of the futon compression bag 23.

  As described above, conventionally, when deaeration is performed from a futon compression bag or a garbage bag in order to reduce the volume, there is a risk that air may flow in after deaeration, and the suction port of the hose of the suction device at the time of deaeration However, there is a problem that there is a risk that the bag may be closed by the contents in the bag. Therefore, the present invention does not have such a problem, i.e., is not limited to the one having a sealing means such as a futon compression bag, and can be widely applied to a bag in general. An object of the present invention is to provide a valve used for in-bag deaeration operation without the possibility of closing the suction port and pulling out the hose after degassing and simultaneously closing the opening so that there is no risk of air inflow. And

  The device according to claim 1 for solving the above-mentioned problems is a hose insertion member that inserts and supports a degassing hose, a closing plate that moves toward and away from the hose insertion member, the closing plate, and the hose. A connecting means for connecting an insertion member, the hose insertion member is a valve used for a degassing operation in a bag that is used by being fixed to the inner surface of a futon compression bag, a garbage bag, etc. A hose insertion hole is provided at the center, and the connecting means always acts so that the blocking plate is in close contact with the hose insertion member, and the blocking plate is inserted through the hose insertion hole. The hose tip is pressed with a force equal to or higher than a predetermined pressure to allow the hose to be separated from the hose insertion member, while at the same time the pressing force is removed, the closing plate is returned to the hose insertion member. Touched A valve for use in bladder degassing, characterized in Rukoto.

  In one embodiment of the present invention, the hose insertion member is a plate material in which the hose insertion hole is formed in the center thereof, or the hose insertion member is a bush-shaped member, The connecting means is locked.

  In one embodiment of the present invention, the connecting means is a rubber band hung on the hose insertion member and the closing plate, and in another embodiment, the connection means is a back surface of the hose insertion member. And a coil spring having a diameter larger than that of the hose insertion hole.

  In still another embodiment of the present invention, a spacer that allows ventilation in the lateral direction is provided in a region corresponding to the hose insertion hole of the blocking plate.

  Since the present invention has the above-mentioned configuration, it is not limited to a large-sized bag having a sealing means such as a futon compression bag, and can be widely applied to bags of various sizes. Since the hose is pulled out after the deaeration is completed and the hose insertion member is blocked by the closing plate, there is no effect of air inflow.

  The best mode for carrying out the present invention will be described with reference to the accompanying drawings. The valve used in the bag deaeration operation according to the present invention includes a hose insertion member, a closing plate 2 that moves toward and away from the hose insertion member, and a connecting means that connects the closing plate 2 and the hose insertion member.

  First, the first embodiment shown in FIGS. 1 to 3 will be described. The hose insertion member shown there is typically a top plate 1 formed in the same contour as the closing plate 2. A hose insertion hole 4 into which a tip of an adapter attached to a hose of a vacuum cleaner, a manual pump or other suction device or a hose tip is formed at the center of the top plate 1. As the connecting means, a rubber band 3 is generally used. For example, two rubber bands 3 are used, each being hooked between the diagonals of the upper surface plate 1 and the closing plate 2 that are overlapped, and connected so that the upper surface plate 1 and the closing plate 2 are always in contact with each other. . In that case, in order to prevent the rubber band 3 from slipping and to maintain its stable hanging state, it is preferable to provide a recess 5 on each side of the top plate 1 and the closing plate 2.

  As the connecting means, a coil spring can be considered in addition to the rubber band 3. In that case, a coil spring having a diameter larger than that of the hose insertion hole 4 is used and fixed to the back surface of the top plate 1 and the top surface of the closing plate 2.

  All of these connecting means always act so that the closing plate 2 abuts against the upper surface plate 1, but the force to contact the hose insertion hole 4 in a state where the upper surface plate 1 is pressed down. When the obstruction plate 2 is pushed with a certain force through, the obstruction plate 2 can be easily separated from the upper surface plate 1.

  The hose 21 (or hose adapter) to be inserted into the hose insertion hole 4 and dedicated for use in this application has an intake port 7 formed on the side surface of the tip (see FIG. 4). ) When using the hose 21 not provided with the air inlet 7, it is preferable to install the spacer 6 on the closing plate 2. The spacer 6 is disposed in a region corresponding to the hose insertion hole 4 of the upper surface plate 1 of the closing plate 2 that overlaps the spacer 6 so as to be in contact with the inner wall of the hose insertion hole 4. For example, as shown in FIG. It is composed of four plates that are spaced apart and extend radially, and the air can be freely vented in the lateral direction from between them.

  In the first embodiment, the upper surface of the upper plate 1 is fixed to the inner surface of the bag 23 by means such as adhesion or welding. Then, after the inside of the bag 23 is filled and closed by tying the opening of the bag 23, etc., in degassing the inside of the bag 23, the portion corresponding to the hose insertion hole 4 of the bag 23 is cut and opened (pre-opened). The tip of the degassing hose 21 is inserted into the hose insertion hole 4 through the opening.

  When the hose 21 is still pushed against the fastening force of the rubber band 3 with the upper surface plate 1 held, the rubber band 3 extends and the closing plate 2 is separated from the upper surface plate 1, and A ventilation space is formed between the face plate 1 and the face plate 1. Air in the bag 23 is sucked into the hose 21 from this ventilation space. At that time, since the stored item in the bag 23 is pushed into the closing plate 2, it does not enter the hose 21 and clog it.

  When the front end surface of the hose 21 is in close contact with the closing plate 2, the suction from the hose 21 is hardly performed. Therefore, for example, as described above, the air inlet 7 is appropriately formed at the tip of the hose 21 so that air can be sucked therethrough. When the air inlet 7 is not provided in the hose 21, the spacer 8 is arranged as described above in order to prevent the front end surface of the hose 21 from coming into contact with the upper surface of the closing plate 2 and being blocked. In this case, the tip of the hose 21 hits the spacer 8, and a ventilation space is created below the spacer 8, so that the air in the bag 23 is sucked out without stagnation.

  When the hose 21 is pulled out from the hose insertion hole 4 while holding the upper surface plate 1 after the deaeration operation is completed, the closing plate 2 immediately contacts the upper surface plate 1 by the action of the rubber band 3, and the hose insertion hole 4 is blocked. Again, air is prevented from entering the bag 23 and the bag 23 being inflated. For the sake of completeness, it is preferable to close the opening of the bag 23 corresponding to the hose insertion hole 4 with an adhesive tape after completion of the work.

  Next, the second embodiment shown in FIGS. 5 to 7 will be described. In this embodiment, the hose insertion member is a bush-like member 11 having a bush shape, and the rubber band 3 as the connecting means is between the flange portion 12 of the bush-like member 11 and the four corners of the closing plate 2. It is hung on.

  Typically, the bush-like member 11 is provided with a fixing portion 12 that protrudes outward in the upper part or in the middle of the cylindrical part. The fixing portion 13 may be integrally formed with the cylindrical portion, or may be separately formed and integrated later. The fixing part 13 fixes the upper surface to the inner surface of the bag 23 by adhesion, welding, or the like (see FIG. 7). In addition, when using the hose 21 which does not have the inlet port 7 in a front-end | tip part, it is the same as the case of the said embodiment that providing the spacer 6 in the obstruction board 2 is preferable.

  In this second embodiment, when the bag is deaerated, the tip of the hose 21 is inserted into the bush-like member 11 and abuts against the closing plate 2 to hold down the fixing portion 13 while tightening the rubber band 3. Then, the closing plate 2 is pushed further away from the flange portion 12 of the bush-like member 11 to form a ventilation space between the closing plate 2 and the bush-like member 11.

  Also in the case of this embodiment, when the hose 21 is pulled out while holding the fixing portion 13 after the deaeration is finished, the bush-like member 11 is immediately and automatically acted by the rubber band 3 as in the case of the above embodiment. It is blocked and air is prevented from entering the bag 23 and the bag 23 from expanding again.

  Needless to say, even when a spring or the like is used instead of the rubber band 3 as the connecting means, the same action as described above is performed.

  Although the invention has been described in some detail with respect to its most preferred embodiment, it will be apparent that a wide variety of different embodiments can be constructed without departing from the spirit and scope of the invention. It is not restricted to the specific embodiment other than limiting in.
