Description

  The present invention consists of an adapter for degassing in a bag, more specifically, two parts connected at the time of use, and a suction device such as a general household vacuum cleaner or a manual pump is used to reduce the bulk. When performing the operation of sucking out the air in the bag such as a futon compression bag or garbage bag, attach one part to the tip of the hose of the suction device and attach the other part to the bag side to deaerate the bag. The present invention relates to an in-bag degassing adapter.

  In order to reduce the bulk at the time of storage, after putting a futon and clothes in the compression bag which can be sealed, the compression bag is sealed and the air in a 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 the futon compression bag 23 is deaerated, 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 electric vacuum cleaner 22 is switched on, the inside of the bag 23 is evacuated, and the fastener 25 is closed after degassing (see FIG. 6). ).

  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.

The insertion hole corresponding portion is cut by opening the tip engaging portion and allowing the tip engaging portion to be inserted by inserting the tip engaging portion. The at least one auxiliary inlet is opened together with one main inlet.

  In another embodiment of the present invention, the closing tool is provided with the one main suction port on the bottom surface, and the cylinder provided with the at least one sub suction port in the lower half portion to be located in the bag. A pedestal, a cover having an upper surface opening into which the tip engaging portion of the hose adapter attached to the pedestal can be fitted, and a spring having a closing plate on the upper surface accommodated in the pedestal. An O-ring is provided on the back surface of the peripheral edge of the upper surface opening of the cover so that the closing plate can be contacted with the O-ring, and the side surface of the fitting portion of the tip engaging portion into the upper surface opening is provided. Ventilation holes are formed in the hood.

  In still another embodiment of the present invention, the closing device is provided with the one main suction port on the bottom surface and the at least one sub suction port in the lower half portion that is located in the bag. From a cylindrical pedestal, a cover having an upper surface opening into which a tip engaging portion of the hose adapter attached to the pedestal can be fitted, and a spring having a closing plate on the upper surface accommodated in the pedestal And an O-ring is fitted on the peripheral side surface of the closing plate, the O-ring is capable of contacting pressure on the rear surface of the peripheral edge of the upper surface opening, and the tip engaging portion is inserted into the upper surface opening. A vent hole is formed on the side surface of the fitting portion. In this case, it is preferable that the back surface of the peripheral edge portion of the upper surface opening with which the O-ring contacts is a tapered surface.

  Since the present invention is configured as described above, the present invention is not limited to a large-sized one provided with a sealing means such as a futon compression bag, and can be widely applied to bags of various sizes, and faces a hose adapter or a closure bag. Since the auxiliary suction port is provided in the part together with the main suction port, there is no risk that the stored items will block the suction port such as the hose adapter during the deaeration operation, and at the same time the hose adapter is pulled out after the deaeration, Since it is automatically closed, there is an effect that there is no fear of air inflow.

  The best mode for carrying out the present invention will be described with reference to the accompanying drawings. The in-bag degassing adapter according to the present invention includes, for example, a hose adapter 1 attached to the tip of a hose 21 of a vacuum cleaner and a closing tool 2 fixed to an arbitrary portion of the bag 23.

  First, the first embodiment shown in FIGS. 1 to 3 will be described. Shown there is a degassing adapter for relatively medium or small bags. In this case, the hose adapter 1 has a connection part 3 that can be connected to the tip of the hose 21 in one half, and a tip engagement part 4 in the other half. In addition to the main inlet 5, at least one auxiliary inlet 5a is opened. In the example shown in the figure, the auxiliary suction port 5a is formed with one large one that passes from one side surface to the other side and two small ones. Preferably, a safety opening 6 for inhaling outside air is provided in the connection portion 3 that will be located outside the bag 23 in use. In the embodiment shown in FIGS. 1 and 2, the connecting portion 3 of the hose adapter 1 has a cylindrical shape, and the tip engaging portion 4 has a rectangular cross section with the connecting portion 3 being crushed. Yes.

  The closing tool 2 includes a base 7 fixed to the bag 23, a cover 8 attached to the base 7, and a resin sheet 9 inserted between the base 7 and the cover 8. And the cover 8 are formed with insertion holes 10 and 11 through which the tip engaging portion 4 of the hose adapter 1 can be inserted. In the embodiment shown in FIGS. 1 and 2, the insertion holes 10 and 11 formed in the base 7 and the cover 8 of the closing tool 2 are horizontally long holes that can be inserted corresponding to the shape of the insertion portion 4. Is done.

  The cover 8 can be inserted into and removed from the base 7 or can be screwed, and the resin sheet 9 can be replaced by removing the cover 8. The pedestal 7 may be fixed to the bag 23 in advance, or may be fixed later. A double-sided tape can be used for the fixing, or an adhesive may be applied to the pedestal in advance to cover the release paper, and the release paper may be peeled off during use. The pedestal 7 is fixed to the bag 23 so as to cover a hole formed in advance, or the pedestal 7 is fixed, and then the bag 23 is drilled through the insertion holes 10 and 11.

  The resin sheet 9 is, for example, a silicone rubber sheet, and a notch 12 is formed in a portion that can be seen through the insertion holes 10 and 11 of the base 7 and the cover 8. When the insertion holes 10 and 11 are horizontally long holes, the notch 12 is one along the hole. The resin sheet 9 may be a relatively thick sheet or a plurality of thin sheets, and in the case of stacking, the cuts 12 overlap each other. However, as will be described later, when the insertion holes 10 and 11 are circular, the cuts 12 may be crossed at the top and bottom.

  The second embodiment shown in FIG. 3 is an adapter for deaeration when a simple suction device such as a bellows type manual pump is mainly used. Here, the hose adapter 1 is entirely circular in cross section, and the insertion holes 10 and 11 of the base 7 and the cover 8 are also circular. In the illustrated example, the hose adapter 1 is stepped to prevent the hose from coming off. In the case of this embodiment, the notches 12 of the resin sheet 9 can be a plurality of crossing lines.

  In the above two embodiments, the bag 23 packed with futon, garbage or the like is used when a sealing means such as a fastener is used, and when there is no such means, the opening is connected by a method such as connecting the openings together. Is closed and the bag 23 is sealed. When the closing tool 2 is not fixed to the bag 23 in advance, it is adhered to an arbitrary portion of the bag 23. Of course, the closing tool 2 may be fixed to the bag 23 before storing the futon or the like.

  Next, the tip engaging portion 4 of the hose adapter 1 is inserted and pushed through the insertion hole 10 of the cover 8, the notch 12 of the resin sheet 9 is penetrated, and the tip is abutted against the bag 23 through the insertion hole 11 of the base 7. . If a hole is made in the bag 23 in advance, the front end engaging portion 4 faces the bag 23 through the hole, and if the hole is not made in advance, the bag 23 is further pushed to break through the bag 23 to engage the front end. The tip of the part 4 is brought into the bag 23.

  Thus, when the electric vacuum cleaner is turned on or the manual pump is operated, the air in the bag 23 is sucked out from the main suction port 5 and the sub suction port 5a of the tip engaging portion 4. At that time, since the front end engaging portion 4 has at least one auxiliary suction port 5a outside the main suction port 5, even if the stored item in the bag 23 is sucked to close one of the suction ports, the other suction ports As the inhalation from the air continues, there will be no hindrance to the deaeration work. Even if the amount of suction is reduced, if the safety opening 6 is provided in the connection portion 3 of the hose adapter 1, the outside air is sucked from there, so that an excessive load is not applied to the vacuum cleaner or the like.

  After the degassing operation is completed, the hose adapter 1 is pulled out from the insertion holes 10 and 11 of the closing tool 2. Simultaneously with the pulling out, the cut 12 of the resin sheet 9 that has been pushed open is closed by the restoring force, and the bag 23 Maintains airtightness. When the resin sheets 9 are laminated, the airtightness is more reliably maintained. In addition, if a tape is stuck on the insertion hole 11 of the cover 8 after completion | finish of deaeration and it will obstruct | occlude, airtightness will become more perfect.

  Next, a third embodiment shown in FIG. 4 will be described. This embodiment is a deaeration adapter for a large bag such as a futon compression bag. In this case, the closing tool 2 includes a cylindrical base 7a, a cover 8a attached to the base 7a, and a base. The hose adapter 1a is formed with a vent hole 13 in the tip engaging portion 4a.

  An upper surface opening 15 into which the tip engaging portion 4a of the hose adapter 1a can be fitted is formed on the upper surface of the cover 8a, and an O-ring 16 is disposed on the rear surface of the peripheral edge of the upper surface opening 15. A flange 17 projecting outward is formed at the lower end of the cover 8a. A flange may be formed in the middle portion of the outer surface of the base 7a instead of or in addition to the flange 17.

  The return spring 14 is, for example, a tapered coil spring that expands downward. A closing plate 18 is fixed to the upper end portion of the return spring 14, and the lower end portion is housed in a recessed portion 19 formed on the inner bottom surface of the base 7a. The recessed portion 19 is formed with one main suction port 20, and at least one sub suction port 20 a is formed in the lower half of the pedestal 7 a, that is, in a portion that will be located in the bag 23.

  In the case of this embodiment, the closing tool 2 is usually fixed to the bag 23 in advance, but when it is retrofitted, the back surface of the flange 17 is fixed to the hole edge of the bag 23 through a double-sided tape or the like. In this fixed state, the upper surface opening 15 is always in a closed state (the state shown by a solid line in FIG. 4) when the closing plate 18 receives the push-up force from the return spring 14 and keeps in pressure contact with the O-ring 16.

  During the deaeration operation, when the tip engaging portion 4a of the hose adapter 1a is inserted into the upper surface opening 15 and further pressed against the push-up force of the return spring 14 after contacting the closing plate 18, the closing plate 18 is It is pushed down to a position close to the inner bottom surface of the pedestal 7a (a position indicated by an imaginary line in FIG. 4). Thus, since the inside of the bag 23 and the inside of the hose adapter 1a communicate with each other through the main suction port 20, the auxiliary suction port 20a, and the vent hole 13, the bag 23 is removed from the bag 23 by a suction device (not shown) to which the hose adapter 1a is connected. It becomes possible.

  When the hose adapter 1a is pulled out from the upper surface opening 15 after the deaeration operation is completed, the closing plate 18 is raised by the action of the return spring 14 and the upper surface opening 15 is automatically closed. Never flows in. As a precaution, the upper surface opening 15 may be closed with an adhesive tape, or a stopper for closing the upper surface opening may be separately prepared and closed.

  By providing at least one auxiliary suction port 20a outside the main suction port 20, even if a part of the bag is blocked by the stored items in the bag, the remaining suction ports 20 and 20a continue the suction, which hinders work. As in the case of the above-described embodiment, it is not necessary to apply an excessive load to the suction device by providing a safety opening in the hose adapter 1a.

  In the fourth embodiment shown in FIG. 5, the mounting position of the O-ring 16 in the third embodiment is changed not to the cover 8a but to the closing plate 18a. That is, the O-ring 16 in this case is fitted on the peripheral side surface of the closing plate 18a. And the peripheral part back surface 15a of the upper surface opening 15 with which the O-ring 16 comes into contact is preferably a tapered surface.

  The action of the fourth embodiment is that the O-ring 16 is allowed to vent away from the peripheral portion back surface 15a as the distal end engaging portion 4a enters the upper surface opening 15, and the upper surface of the distal end engaging portion 4a. As in the case of the third embodiment, the O-ring 16 is brought into pressure contact with the peripheral edge rear surface 15a in accordance with the extraction from the opening 15 and enters the air blocking state. Note that the fourth embodiment is easier to manufacture than the third embodiment, and the accuracy of the contacts of the O-ring 16 is increased.

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