JP-A-1-139346 No. 7-2417

  However, conventionally, since the bag body is in a negative pressure state during the deaeration of the bag body by the exhaust valve mechanism, the air flow passage of the trunk in the exhaust valve mechanism is blocked by the storage items such as the futon and clothing. As a result, there is a risk that reliable deaeration cannot be performed.

  Therefore, the present invention was created in view of the existing circumstances as described above, and the air flow passage is accommodated when the bag body is deaerated using an exhaust nozzle such as a vacuum cleaner or an intake mechanism. It is an object of the present invention to provide a compressed storage bag that can be prevented from being blocked by an object and can be surely evacuated.

In order to solve the above-described problems, in the present invention, the futon / clothing P is accommodated from the opening 2 in the bag 1 and the opening 2 is closed, and the exhaust nozzle of the vacuum cleaner or the intake mechanism. In a compressed storage bag in which N is connected to an exhaust valve mechanism Q provided at an arbitrary position on the side of the bag body 1 to exhaust the air in the bag body 1 and store the futon / clothes P in a compressed state. The exhaust valve mechanism Q has a body 4 having an air flow passage R communicating with the inside of the bag body 1 and is fitted to the body 4 so as to be slidable up and down, and the air flow through the air flow path R is reduced. A support plate 5 having an exhaust valve 6 to be controlled, and an upright plate 7 for holding the contents so that the contents of the bag 1 do not come into contact with the air flow path R of the fuselage 4 around the air flow path R of the fuselage 4 Is formed radially in the radial direction.
Further, the body 4 is formed by extending a disk-shaped fixing plate 4a to the outer peripheral edge so that the fixing plate 4a can be heat-sealed so as to bite into the inner surface of the through hole 1c of the bag body 1. A concentric ring groove 4d is provided on the upper surface of the fixed plate 4a.
Further, the upright plate 7 can be provided continuously with the body 4 with an exhaust notch 4e formed in the vicinity of the air flow passage P on the center side.

In the compression storage bag according to the present invention configured as described above, the bag is provided by an exhaust nozzle N of a vacuum cleaner or an intake mechanism connected to an exhaust valve mechanism Q provided at an arbitrary position on the side of the bag body 1. The bag 1 is contracted by degassing the inside of the body 1.
At this time, when the vacuum cleaner or the intake mechanism is operated, the exhaust valve mechanism Q is moved upward by the negative pressure of the upper surface of the exhaust valve 6 according to the Bernoulli principle, and the air flow path below the center of the fuselage 4 R is opened, and the air in the bag 1 can be deaerated by the exhaust nozzle N.
At the same time, the upright plate 7 formed radially outward from the periphery of the air flow path R of the body 4 prevents the contents of the bag 1 from contacting the air flow path R of the body 4. Blockage of the air flow passage R is prevented.
Further, when the exhaust nozzle N is removed from the exhaust valve mechanism Q after deaeration, the exhaust valve 6 is lowered by the external pressure, and the bag body 1 can be kept airtight by sealing the air flow passage R below the center of the body 4. Let me.
Further, the notch 4e formed in the vicinity of the air flow passage P on the center side of the upright plate 7 reduces resistance to the air flow to the air flow passage R during deaeration.

  According to the present invention, it is possible to prevent the airflow passage R from being blocked by the contents when the bag 1 is deaerated using the exhaust nozzle N of a vacuum cleaner or an intake mechanism. The degassing inside the bag body 1 can be performed.

  That is, this is because the present invention radiates the upright plate 7 that holds the contents so that the contents of the bag 1 do not come into contact with the air flow path R of the fuselage 4 radially outward from the periphery of the air flow path R of the fuselage 4. This is because it is formed.

  Further, the body 4 is formed by extending a disk-shaped fixing plate 4a to the outer peripheral edge so that the fixing plate 4a can be heat-sealed so as to bite into the inner surface of the through hole 1c of the bag body 1. Since the concentric ring groove 4d is provided on the upper surface of the fixing plate 4a, the fixing of the body 4 with respect to the inner surface of the through hole 1c of the bag body 1 is completely sealed and securely attached. Adhesion between the inner surface of the hole 1c and the body 4 becomes strong.

  And since the air in the bag body 1 is brought into a backflow prevention state by the exhaust valve mechanism Q provided at an arbitrary position on the side surface of the bag body 1 while the opening 2 is sealed, the air is deaerated. When the exhaust nozzle N is extracted after deaeration, the intrusion of air into the bag body 1 can be completely prevented. In addition, since the futon, clothing P, etc. can be stored in a state in which the bulk is reduced by the bag body 1, it is possible to effectively use the storage space at home.

  Further, the exhaust valve mechanism Q is provided at an arbitrary position on the side surface of the bag body 1 and has a body 4 having an air flow passage R communicating with the inside of the bag body 1 and is fitted to the body 4 and can slide up and down. And a support plate 5 provided with an exhaust valve 6 for controlling the flow of air through the air flow passage R. When the vacuum cleaner or the intake mechanism is operated, the exhaust valve 6 is operated according to the Bernoulli principle. The upper surface is moved upward with a negative pressure, and the air flow passage R below the center of the body 4 is opened, so that the air in the bag body 1 can be deaerated by the exhaust nozzle N. At the same time, when the exhaust nozzle N is removed from the exhaust valve mechanism Q after deaeration, the exhaust valve 6 is lowered by the external pressure, and the air flow passage R below the center of the body 4 is sealed to keep the bag body 1 airtight. Therefore, the suction load on the vacuum cleaner or the intake mechanism can be reduced, and the exhaust can be performed smoothly. As a result, the futon / clothes P are sealed together with the bag 2 in an efficiently compressed state. I can leave.

  Further, since the upright plate 7 is connected to the body 4 with a notch 4e formed in the vicinity of the air flow passage P which is the center side, the upright plate 7 can prevent the air flow to the air flow passage R during deaeration. The resistance is reduced, and the bag body 1 can be efficiently and smoothly deaerated.

  Note that the reference numerals added in the means for solving the above-described problems and the effects of the invention are given for easy reference to the parts showing the components shown in the drawings. The present invention is not limited to the structure / shape indicated by the reference numeral.

  The best mode for carrying out the present invention will be described below with reference to the drawings. Reference numeral 1 shown in the figure is a bag body for storing a futon, clothing P, etc. in a compressed state, and the bag body 1 is a pair of soft synthetic resin sheets 1a as shown in FIG. , 1b are heat-sealed to form a bag having an opening 2 at one end.

  That is, the bag 1 is made from, for example, a transparent plastic film. Specifically, the material of the film is preferably a laminated sheet of nylon or polyethylene having gas barrier properties. The bag body 1 can be colored or printed on the surface.

  Moreover, the sealing means 3 by the fastener structure which can be closely_contact | adhered and peeled from the one end of the opening part 2 of the bag body 1 to the other end is provided. In this sealing means 3, in use, after inserting a futon, clothing P, etc. from the opening 2 of the bag body 1, the fold-shaped slider S is sandwiched from the end of the sealing means 3 and slid while firmly pressing. The bag body is closed by degassing the inside of the bag body 1 by a vacuum cleaner or an exhaust nozzle N of an intake mechanism connected to an exhaust valve mechanism Q, which will be described later, provided at an arbitrary position on the side surface of the bag body 1. 1 is to be compressed.

  In this embodiment, a pair of male and female fasteners are formed in a row so that the sealing means 3 in the opening 2 meshes with each other from one end to the other end of the opening 2. The pair of male and female fasteners may be formed in two or three rows in the opening 2.

  Further, an exhaust valve mechanism Q for connecting and exhausting the air in the bag body 1 in a backflow-preventing state by connecting a vacuum cleaner or an exhaust nozzle N of the suction mechanism is attached to an arbitrary position on the side surface of the bag body 1. ing.

  As shown in FIG. 2, the exhaust valve mechanism Q includes a body 4 fixed to the inner surface of a through hole 1 c drilled at an arbitrary position of the bag body 1 by heat fusion or the like, and a through hole of the bag body 1. A disc-shaped support plate 5 fitted to the body 4 from the outer surface of the bag body 1 at a portion 1c, and a cylindrical hole 5b formed in an inward step shape in the center of the support plate 5 The exhaust valve 6 is movable and has an upper surface exposed.

  That is, an air flow passage R having a stepped diameter is formed on the lower side of the center of the body 4, and a disk-shaped fixing plate 4 a is extended on the outer peripheral edge of the body 4. As shown in FIGS. 5 and 6, standing plates 7 are radially formed on the lower surface of the fixed plate 4 a radially outward from the periphery of the air flow passage R of the body 4. It is assumed that the futon / clothing P or the like is pressed against the air flow passage R to hold the contents. Further, on the inner side of the body 4, a protruding guide portion 4 c that is integrated with each of the four upright plates 7 arranged in a cross shape via ribs 4 b is erected in the center. Therefore, an arc-shaped opening surrounded by the body 4, the guide portion 4c, and the rib 4b serves as an inlet to the air flow path R.

  As shown in FIG. 3C, the other upright plate 7 is not connected to the guide portion 4 c and is connected to the body 4 as a rectangular cutout portion 4 e on the center side. The presence of the cutout 4e greatly reduces the resistance to the airflow to the airflow passage R during degassing, so that the inside of the bag body 1 can be efficiently degassed.

  In addition, a plurality of concentric ring grooves 4d are provided on the upper surface of the fixed plate 4a. The fixing plate 4a is heat-sealed to the inner surface around the through hole 1c of the bag body 1 so as to bite into the ring groove 4d, and the outside of the body 4 protruding outward from the through hole 1c of the bag body 1 Assume that the peripheral edge is fitted to a diameter-enlarged inner peripheral surface provided in a stepped shape from the cylindrical hole 5b on the lower surface of the support plate 5 so that the upper surface of the exhaust valve 6 is exposed outward from the cylindrical hole 5b. is there. Each of the fixed plate 4 a and the support plate 5 has substantially the same outer diameter that is larger than the diameter of the exhaust valve 6.

  On the upper surface of the support plate 5, air inflow projections 5 a for allowing outside air to flow are formed, for example, slightly raised so as to be radially formed, and the tip of the exhaust nozzle N connected to the protrusion 5 a and the upper surface of the support plate 5 are formed. It is isolated by a predetermined interval.

  The cylindrical hole 5b of the support plate 5 is fitted with a circular lid-like exhaust valve 6 that can slide up and down and controls the flow of air through the air flow passage R of the body 4. . That is, a cylindrical insertion portion 6a into which the guide portion 4c of the body 4 is inserted protrudes from the center of the lower surface of the exhaust valve 6, and the air flow located below the center of the body 4 is provided at the outer periphery of the distal end of the insertion portion 6a. A 0-ring-shaped seal member 8 is attached to the inner wall of the path R to fix the exhaust valve 6 itself. Further, a longitudinally long rib 6c protrudes from the front and rear symmetrical positions of the outer peripheral surface of the insertion portion 6a, and the lower end of the rib 6c is locked to protrude in the outer diameter direction so as to be locked to the cylindrical hole 5b of the support plate 5. A portion 6b is formed, which restricts the separation and lifting width of the exhaust valve 6. Further, a pair of guide leg portions 6d that are spaced from each other so as to oppose the insertion portion 6a is provided vertically at a symmetrical position at the substantially peripheral edge of the lower surface of the exhaust valve 6.

  When the exhaust valve 6 moves upward from the cylindrical hole 5b of the support plate 5 while being supported by the guide leg 6d, the insertion portion 6a of the exhaust valve 6 and the guide portion 4c of the body 4 are separated from each other. Since the locking portion 6 b of the exhaust valve 6 is locked in the cylindrical hole 5 b of the support plate 5, a flow path communicating with the air flow path R of the body 4 is provided between the support plate 5 and the exhaust valve 6. It is formed so that exhaust can be performed.

  When the bag 1 is used, the exhaust nozzle N is connected to the exhaust valve mechanism Q so as to cover the body 4 as shown in FIGS. 3 (a) and 4 (a). When the vacuum cleaner or the intake mechanism is operated, the tip of the exhaust nozzle N and the upper surface of the support plate 5 are separated by a predetermined interval via the air inflow projection 5a. Then, the outside air flows in, the upper surface of the exhaust valve 6 moves upward with a negative pressure by Bernoulli's theorem, the air flow passage R below the center of the body 4 is opened, and the air in the bag body 1 is exhausted. Degassing is enabled by the nozzle N.

  On the other hand, after the deaeration, as shown in FIGS. 3B and 4B, when the exhaust nozzle N is removed from the exhaust valve mechanism Q, the exhaust valve 6 is pushed down by the external pressure, and the exhaust valve 6 The guide portion 4c of the fuselage 4 is inserted into the insertion portion 6a, and the peripheral portion of the exhaust valve 6 is locked to the upper edge of the cylindrical hole 5b of the support plate 5, and at the same time, the outer peripheral surface of the insertion portion 6a is the air of the fuselage 4. The air flow passage R is hermetically sealed by being inserted into the inner wall of the flow passage R. At this time, by pushing the exhaust valve 6 further downward with fingers, the seal member 8 is firmly fitted to the inner wall of the air flow path R of the body 4 to fix the exhaust valve 6 itself.

  Next, an example of use of the best mode configured as described above will be described. First, as shown in FIG. 1, a futon, clothing P, etc. are inserted from the through-hole 1c of the bag body 1, and the two-folded slider S is sandwiched from the end of the sealing means 3 having a fastener structure and slid while firmly pressing. In this way, the opening 2 is tightly closed.

  And as shown to Fig.3 (a) or FIG.4 (a), the exhaust nozzle N is connected to the exhaust valve mechanism Q, and a vacuum cleaner or an intake mechanism is operated. At this time, the exhaust valve 6 moves upward with a negative pressure on the upper surface according to the Bernoulli principle, and the insertion portion 6a of the exhaust valve 6 and the guide portion 4c of the body 4 are separated from each other, so that the engagement portion of the exhaust valve 6 is separated. By engaging 6 b with the cylindrical hole 5 b of the support plate 5, a flow path communicating with the air flow passage R of the body 4 is formed between the support plate 5 and the exhaust valve 6. Thus, the air flow passage R of the body 4 is opened by the exhaust valve 6, and the air in the bag body 1 is deaerated by the exhaust nozzle N, whereby the entire bag body 1 contracts, and the interior accompanying the contraction It is compressed almost uniformly with the futon / clothes P.

  On the other hand, as shown in FIG. 3B or FIG. 4B, when the exhaust nozzle N is removed from the exhaust valve mechanism Q after deaeration, the exhaust valve 6 is pushed down by the external pressure, and the exhaust valve 6 Since the peripheral edge portion of the body 4 is locked to the upper edge of the cylindrical hole 5b of the support plate 5, the air flow path R of the body 4 is sealed, and air intrusion into the bag body 1 is completely prevented. is there. At this time, the exhaust valve 6 is forcibly pushed downward with fingers, so that the seal member 8 is firmly fitted so as to bite into the inner wall of the air flow path R on the lower center side of the body 4, thereby allowing the exhaust valve 6. It is fixed securely.
