Abstract

PROBLEM TO BE SOLVED: To obtain an air exhaustion tool of which an inlet port is not blocked by a futon during air exhaustion.SOLUTION: When a suction port of a vacuum cleaner is brought into contact with a front side of a valve chamber 3a of an air exhaustion tool 1 and sucks internal air from an exhaust window 3d, a negative pressure is generated in an internal space of the valve chamber 3a, and a valve body 4a of a valve member 4, which covers an intake air introduction window 2d, is floated and is separated from a valve seat part 2c in the valve chamber 3a, thereby opening the intake air introduction window 2d. Air in a compression storage bag B is guided by a diaphragm 2g and is flown into an inner member 2 from below the diaphragm 2g of the inner member 2 and an intake window 2j, and further, the air gets to the intake air introduction window 2d along the partition wall 2b, and is sucked into the vacuum cleaner from the exhaust window 3d of an outer member 3. A futon F is stuck to lower edges of a partition wall 2b and the diaphragm 2g as air exhaustion advances, and in association with this, a flow of air from below is blocked by the futon F, and even if air intake from below is blocked, an airflow path from the intake window 2j to the intake air introduction window 2d via the partition wall 2b is assured.SELECTED DRAWING: Figure 6

Description

  The present invention relates to an exhaust device for a compressed storage bag that is used by being assembled to a compressed storage bag and compresses and stores stored items such as futons, cushions, and clothes.

  Articles such as futons, cushions, and clothes are preferably in a bulky state containing a lot of air during use. However, the bulkiness becomes a problem during storage.

  Therefore, in order to prevent the futons from becoming bulky when storing the futons, compression storage bags are used. The compression storage bag is equipped with an exhaust valve composed of a check valve. When a futon is stored in the compression storage bag, for example, when the suction port of the vacuum cleaner is placed against the exhaust valve and sucked, the exhaust valve that closes the exhaust port is It opens by the suction force of the machine, and the air in the compressed storage bag is discharged to the outside through the exhaust port, and the air can be compressed by extracting air from the futon. When the suction is stopped, the inside of the compression storage bag becomes negative pressure and the outside becomes positive pressure. Due to this pressure difference, the exhaust valve closes the exhaust port and maintains the compressed state in which the air in the futon is removed. Can do.

  However, when such a compressed storage bag is exhausted, if the intake port is blocked by a part of the futon that is sucked in, the exhaust is stopped and rapid exhaust cannot be performed. Therefore, Patent Document 1 discloses an exhaust valve that prevents the suction port from being blocked by a futon during exhaust.

  This patent document 1 discloses that “a body 4 having an air flow passage R communicating with the inside of a bag body 1, and an upright plate that holds the contents so that the contents of the bag body 1 do not contact the air flow path R of the body 4. 7 and an exhaust valve mechanism Q that is formed radially from the periphery of the air flow passage R of the body 4 in the radially outward direction. And in deaeration, it can prevent that the airflow path R is obstruct | occluded with a contained thing, and can deaerate the bag body.

It consists of three members, and the valve member 4 is disposed between the inner member 2 and the outer member 3.

  The inner member 2 has a valve holding cylinder 2a at the center, and for example, eight plate-like partition walls 2b are arranged radially outward at equal angles around the valve holding cylinder 2a. A valve seat 2c whose upper surface is an annular flat surface is connected to the upper outer end of each partition wall 2b, and the upper edges of the valve holding cylinder 2a and the partition wall 2b appear in the inner edge of the valve seat 2c. The space between the partition walls 2b at the inner edge of the valve seat 2c is an intake air introduction window 2d.

  An annular lower holding plate 2e is connected to the periphery of the valve seat portion 2c. The valve seat portion 2c has a shorter cylindrical shape than the lower holding plate 2e. 2f is formed in an annular shape.

  On the lower surface of the lower holding plate 2e, for example, twelve plate-like partition walls 2g are arranged radially at an equal angle around the valve holding cylinder 2a, and the partition walls 2g protrude downward.

  The lower edges of these partition walls 2g are substantially at the same position as the lower edges of the partition walls 2b, and the respective ends of the partition walls 2g extend further outward than the outer periphery of the annular lower retaining plate 2e. The upper edge 2h of the partition wall 2g located on the front side of the plate 2e is often inclined obliquely downward.

  Further, an annular ring frame portion 2i is disposed outside the partition wall 2g, and each end of the partition wall 2g is connected to the inside of the ring frame portion 2i.

  Although the exhaust device 1 of the present embodiment is sold as a single unit, many of the exhaust devices are commercially available assembled to the exhaust hole of the compression storage bag. A compression storage bag made of a synthetic resin sheet material for storing a stored item such as a futon F has air barrier properties, transparency, and flexibility.

  The compression storage bag has a storage opening in which a sealing fastener for storing the futon in a sealed state is attached to the edge, and a circular exhaust hole for mounting the exhaust device 1 for discharging the internal air. Are provided. The diameter of the exhaust hole portion substantially matches the diameter of the valve seat portion 2c.

  When the exhaust device 1 is assembled to the compression storage bag, as shown in FIG. 5, the valve seat portion 2c of the inner member 2 is inserted into the exhaust hole portion of the compression storage bag B, and the peripheral edge of the exhaust hole portion is lowered to the lower portion. Airtightly joined to the holding plate 2e by melting or bonding. Subsequently, when the valve member 4 is attached to the inner member 2, the shaft portion 4b is inserted into the valve holding cylinder 2a, and the valve body 4a is placed on the valve seat portion 2c, the valve body 4a covers the intake introduction window 2d. It will be.

  Next, the outer member 3 is brought into contact with the inner member 2, and the locking piece 3b of the valve chamber 3a is locked to the recess 2f of the valve seat portion 2c. Thereby, the valve chamber 3a covers and fits the valve seat portion 2c, and the periphery of the exhaust hole of the compressed storage bag B bonded to the lower holding plate 2e is connected to the lower holding plate 2e of the inner member 2 and the outer member. 3, and the assembly of the exhaust device 1 to the compressed storage bag B is completed. In this state, the compressed storage bag B is folded and marketed.

  In use, the user expands the compressed storage bag B assembled with the purchased exhaust device 1 and stores, for example, a futon from the storage opening of the compressed storage bag B, and then closes the storage opening to fasten the fastener. Seal with.

  Next, the suction port S of the vacuum cleaner is brought into contact with the front side of the valve chamber 3a of the exhaust tool 1 to suck the internal air from the exhaust window 3d. Then, the internal space of the valve chamber 3a becomes negative pressure, and as shown in FIG. 6, the valve body 4a of the valve member 4 covering the intake introduction window 2d floats along the valve holding cylinder 2a in the valve chamber 3a. Then, the air intake window 2d is opened away from the valve seat portion 2c.

  Therefore, the air in the compressed storage bag B, particularly the air contained in the futon F, is sucked out, and this air is guided by the partition wall 2g below the partition wall 2g of the inner member 2 and into the inner member 2 from the intake window 2j. Then, the air flows into a large amount, reaches the intake inlet window 2d partitioned by the partition wall 2b, and is sucked into the vacuum cleaner from the exhaust window 3d of the outer member 3 through the intake inlet window 2d. As the exhaust proceeds, the futon F tries to enter between the partition walls 2b. However, since the annular frame 2i exists, the futon F can only enter a predetermined height.

  The air flow toward the partition wall 2g through the intake window 2j is not blocked by the futon F, and an air flow path to the intake introduction window 2d is always secured.

  The air in the futon F of the entire futon F can be exhausted through this air flow path. Therefore, the air in the compressed storage bag B can be quickly exhausted without the air flow being obstructed by the clogging of the futon F with respect to the intake inlet window 2d. In this manner, by providing the annular frame portion 2i outside the partition wall 2g, the air intake passage is secured through the intake window 2j without the intake port being blocked by the futon F during exhaust, and the short Exhaust can be completed in time.

  When the exhaust is further continued and the inner futon F is sufficiently compressed, as shown in FIG. 7, the periphery of the exhaust hole of the compression storage bag B is finally attached to the intake window 2j, and the intake window 2j is I will close it.

  In this state, when suction by the vacuum cleaner is stopped and the suction port S of the vacuum cleaner is removed from the exhaust tool 1, the valve body 4a has a valve seat portion 2c as shown in FIG. The inside of the compressed storage bag B that is adsorbed by the intake air introduction window 2d is kept sealed. Thereby, the futon F can be stored for a long period of time, for example, by pushing it in while being compressed in the compressed storage bag B.

  In order to take out the futon F from the compressed storage bag B, when the fastener of the storage opening is opened, outside air flows into the compressed storage bag B, and the futon F absorbs air and restores its original shape. .
