Description

    TECHNICAL FIELD
  • The present invention relates to a deaerator-carrying compression bag that can be used as a deaerator-carrying compression bag used for compressing and storing bedding, clothes etc. [0001]
  • BACKGROUND ART
  • Conventionally, a deaerating valve has been provided to a peripheral edge of a deaerator-carrying compression bag. When such deaerating valve is provided to the edge of the bag, an intermediate portion of deaerating valve is ordinarily welded to the bag body while base end of the bag is extended to the inside of the bag and distal end is exposed to the outside of the bag. Articles to be stored are compressed in the deaerator carrying compression bag by inserting a nozzle of deaerating pump into the deaerating valve to deaerate the air inside the bag. [0002]
  • However, in order to suck the air inside the bag according to the above-described operation, the nozzle has to be inserted deeper than the end of the deaerating valve located inside the bag, which accompanies much trouble when the articles to be stored is accommodated inside the bag. Further, when adhesive is coated inside the deaerating valve, the portion of the deaerating valve extended to the interior side relative to the outer peripheral edge of the bag body sticks to the nozzle, so that the nozzle is difficult to be drawn out and the deaerating valve can be damaged by forcibly drawing out the nozzle. [0003]
  • An object of the present invention it to provide a deaerator-carrying compression valve capable of deaeration without inserting the nozzle of the deaerating pump deep into the bag body. [0004]
  • DISCLOSURE OF THE INVENTION
  • According to an aspect of the present invention, the above object is achieved by welding a deaerator to a bag body at a base end of the deaerator. [0005]
  • Specifically, a deaerator-carrying compression bag according to an aspect of the present invention has: a resin-made bag body having an opening for an article to be put in at a side of an outer peripheral edge thereof; a snap fastener provided on inner surface of the bag body for closing the opening; and a resin-made deaerator for discharging air inside the bag body, in which the deaerator and the bag body am welded at a base end of the deaerator, and the deaerator has a back-flow preventing as for preventing the air from back-flowing into an inside of the bag body. [0006]
  • An example of the snap fastener of the present invention is a sealing type fastener having a male member formed in a convex tread along an opening periphery of the bag and a female member formed in a concave tread along the opening periphery, however, such male member and female member may not be provided and any snap fastener may be used as long as the bag can be scaled and opened/closed. [0007]
  • Any deaerator may be used as long as the air can be discharged through a nozzle etc. of deaerating pump, which may be a bag formed by superposing two resin films of which outer peripheral edge has opposing two sides being opened. [0008]
  • The back-flow preventing means of the put invention may preferably include a check-valve structure. Further, a fitting member may be combined with the check-valve structure. The back-flow preventing means may be provided anywhere between the base end to the distal end of the deaerator. However, when a bulky check-valve structure is used, the back-flow preventing means may preferably be provided around the distal end so that bulkiness in thickness direction of the bag can be avoided. [0009]
  • According to the above aspect of the present invention, the deaerator and the bag body are welded at the base end of the resin-made deaerator. Since the base end of the deaerator does not extend into the bag, even when a nozzle of deaerating pump etc. is inserted into the inside of the bag body for deaeration troublesome work for inserting the nozzle deep into the bag body is not necessary. Therefore, the nozzle can be easily drawn out after deaeration and damage on the deaerator in twins out the nozzle can be prevented. [0010]
  • Since the back-flow preventing means for preventing the back-flow of the air into the inside of the bag body is provided to the deaerator, the air can be prevented from back-flowing into the inside of the bag body when the air is discharged form the inside of the bag body for compressing, so that deaerating work can be facilitated. [0011]
  • In the present invention, the deaerator may preferably be located approximately at the center of the bag body. [0012]
  • According to the above arrangement, the donator is located approximately at the center of the bag body, so that the air can be uniformly discharged in deaerating the air inside the bag body since deformation of the bag body is unlikely, thus facilitating the deaerating work. In other words, when the deaerator is located at the edge of the bag body, the resin films are stuck or deformed due to decompression during the deaerating process, so that the air at the portion remote from the deaerator is difficult to be drawn out. However, since the deaerator is located at approximately the central portion, such problem can be avoided. [0013]
  • In the present invention, the back-flow preventing means of the present invention may preferably include a check-valve structure. [0014]
  • The structure of the check-valve structure of the present invention is not specifically limited as long as air flow into the inside of the bag body can be prevented. For example, the check-valve may be formed by thermally welding a pair of opposing edges of two films and the other opposing par of edges as an air-discharging opening. According to such film-shaped valve structure, when the air inside the bag is discharged, the films are mutually stuck to temporarily prevent the back-flow. Further, the opening of the film check-valve structure may be shut by a fitting component such as a clip for maintaining compressed condition for a long time. [0015]
  • According to the present invention, the check-valve structure is provided to the deaerator-carrying compression bag, the outside air can be prevented from flowing into the inside of the bag body after discharging the air inside the bag body, thereby easily set the bag body in a compressed condition. [0016]
  • In the present invention, a fitting member having a male member and a female member which are fitted to seal the inside of the bag body may preferably be provided to the back-flow preventing means. [0017]
  • The fitting member of the present invention may be, for instance, a fastener tape such as a zipper tape or chuck tape in which a resin male member formed in convex tread and a resin female member formed in concave tread are fitted to be openable/closable and sealable and a fitting component attached to the outside of the back-flow preventing means, however, any openable/closable and sealable structure may be used. The number of fitting member provided to the deaerator is not limited, which may be one or more. [0018]
  • According to the present invention, since the fitting member is provided to the back-flow preventing means, the compressed condition of the bag body can be maintained for a long time by fitting the fitting member. [0019]
  • Further, since the fitting member is not so bury, not so much space is required for storing a plurality of deaerator carrying compression bag in piles and the film surface of the other bag is not damaged in storing in piles.[0020]

  • [First Embodiment][0027]
  • FIGS. [0028] 1 to 4 illustrate a deaerator compression bag 1 according to first embodiment of the present invention
  • The deaerator carrying compression bag [0029] 1 has a bag body 10, a fastener 12 as a snap zipper provided adjacent to an opening 11A formed on a side of an outer peripheral edge 11 of the bag body 10, a resin-made deaerator 13 having bag-shape with two sides thereof being opened, and a check valve structure 15 as a back-flow preventing means.
  • The bag body [0030] 10 has a side seal 11B and a bottom seal 11C formed on a resin film 14 constituting the bag body 10, the respective seals 11B and 11C welding resin filmy 14 of two upper films and one lower films (total three: see FIGS. 2 and 3). Two resin films 14A and 14B forming upper side are welded by an upper seal 11D on a side slightly near the bottom seal 11C from the center of the surface surrounded by the outer peripheral edge 11 of the bag body 10.
  • Further, a base end [0031] 13A of the deaerator 13 is interposed approximately at the center of the upper seal 11D and welded integrally with two resin films 14A and 14B to keep air-tightness. In other words, the deaerator 13 is welded to the bag body 10 at the base end 13A of the deaerator 13.
  • In the above, the respective resin films [0032] 14A, 14B and 14C are composed of multi-layered film made by laminating biaxially-oriented nylon (ONY) film which does not permeate gas and linear low-density polyethylene (LLDPE) film as an inner layer (welded layer).
  • As shown in FIGS. 1 and 2, the deaerator [0033] 13 is formed in a bag-shape having two open sides by welding two resin films 131 and 132 at a seal 13C. As described above, the base end 13A of the deaerator 13 is attached to an inner side of the outer peripheral edge 11 of the bag body 10, i.e. to an upper side of the bag body 10, and the distal end 13B extends adjacent to the bag body 10. Further, the two resin films 131 and 132 are ordinarily adhered. During deaerating process, the two resin turns 131 and 132 of the deaerator 13 are rapidly adhered after drawing out the nozzle of the deaerator pump to form a check valve structure 15 that prevents air flow into the inside of the bag body 10.
  • Incidentally, the material of the resin films [0034] 131 and 132 forming the deaerator 13 may be, for instance, LLDPE.
  • As shown in FIGS. 2 and 4, the fastener [0035] 12 is composed of a male member 12A aid a female member 12B. The male member 12A is welded to the inside of the resin film 14A forming the upper surface of the bag body 10 and the female member 12B is welded to the inside of the resin film 14C forming the lower of the bag body 10. The male member 12A has a base 121 of continuous band to be welded, and a convex tread 122 extending perpendicular to the base 121 and having distal end widened in width direction. On the other hand, the female member 12B has a base 124 to be a welded portion continuously extending in a band shape and a concave tread 2 integrated with the base 124, the convex tread 122 being fastened to the concave tread 125.
  • The concave tread [0036] 125 is composed of an arc-shaped first claw 125A rising form the base 124 and another arc-shaped second claw 125B opposing the first claw 125A. The convex tread 122 of the male member 12A is fastened to a gap 126 formed by the claws 125A and 125B, so that the outer surface of the convex tread 122 and the inner surface of the concave tread 125 being in facto-face contact to obtain excellent airtightness.
  • The material of the fastener [0037] 12 may be, for instance, the above-described LLDPE.
  • Thus constructed deaerator-carrying compression bag [0038] 1 is used according to the following steps. Initially, while the fastener 12 is open, articles 16 to be stored such as beddings is put into the inside of the bag body 10 and the male member 12A and the female member 12B of the fastener 12 are fastened and stuck to be closed. In this condition, the nozzle of the deaerating pump etc. is inserted into to bag-shaped deaerator 13 to discharge the air inside the bag body by the deaerating pump to the outside. At this time, it is not necessary to insert the nozzle of the deaerating pump deep into the inside of the bag body but may only be inserted to go a small distance into the inside of the bag body from the base end 13A of the deaerator 13. After sufficiently deaerating the air inside the bag body 10 to compress the articles 16 to be stored by the above operation, the nozzle of the deaerating pump is drawn out to finish the work.
  • During the deaerating process, by inserting the nozzle of the deaerating pump, the resin films [0039] 131 and 132 constituting the check-valve structure is are separated to form a space corresponding to the nozzle diameter inside the deaerator 13. On the other hand, when the nozzle of the deaerating pump is drawn out after completion of the denting process, the two resin films 131 and 132 are rapidly stuck to keep sealed condition.
  • The opening of the deaerator [0040] 13 may be shut with a fitting member etc. for keeping the sealed condition for a long time.
  • According to the above first embodiment, following effects can be obtained [0041]
  • (1) The deaerator [0042] 13 and the bag body 10 are welded at the base end 13A of the deaerator 13. Accordingly, the base end 13A of the deaerator 13 does not extend into the inside of the bag body 10, so tat, when the nozzle of deaerating pump etc. is inserted into the inside of the bag body 10 for deaeration, troublesome work for deaerating the nozzle of the deaerating pump deep into the bag body 10 is not necessary.
  • (2) Since it is not necessary to insert the nozzle of the deaerating pump deep into the bag body [0043] 10, the nozzle can be easily drawn out deaeration, and the resin films 131 and 132 of the deaerator 13 are not damaged in drawing-out the nozzle.
  • (3) Since the base end [0044] 13A of the deaerator 13 is located inside the outer peripheral edge 11 of the bag body 10, specifically, appropriately at the central portion thereof, the air can be uniformly discharged in deaerating the air inside the bag body 10 since deformation of the bag body 10 is unlikely, so that the deaerating work can be easily conducted. In other words, when the deaerator 13 is located at the edge of the bag body 10, the resin films 14A and 14C are stuck or deformed due to decompression during the deaerating process, so that the air at the portion remote from the deaerator 13 is difficult to be drawn out. However, since the deaerator 13 is located approximately at the central portion, such problem can be avoided.
  • (4) Since the check-valve structure [0045] 15 is composed of two resin films 131 and 132, not so much space is required for storing a plurality of deaerator carrying compression bag 1 in piles and the film surface of the other bag is not damaged in storing in piles.
  • (5) Since the check-valve structure [0046] 15 is provided to the deaerator-carrying compression bag 1, the outside air can be prevented from flowing into the inside of the bag body 10 after discharging the air inside the bag body 10.
  • (6) Since the check-valve structure [0047] 15 composed of two resin films 131 and 132 is used, it is not necessary to seal the check-valve structure 15 after discharging the air inside the bag body 10, so that compression work can be facilitated.
  • [Second Embodiment][0048]
  • FIG. 5 shows a deaerator-carrying compression bag [0049] 2 according to second embodiment of the present invention.
  • In the following description, the components different from the above-described first embodiment will be described in detail, and die sane reference numeral will be attached to the same components and structures to omit or simplify the detailed description thereof. [0050]
  • The deaerator-carrying compression bag [0051] 2 according to the present embodiment is the same as the first embodiment except for providing a fitting member 25 to the check-valve structure 15 as a back-flow preventing means around the inside of the distal end 13B of the deaerator 13.
  • The fitting member [0052] 25 is a fastener tape composed of a male member 25A and a female member 25B similar to the fastener 12 provided around the opening 11A of the bag body 10. The male member 25A has a convex tread rising in the width direction of the deaerator 13 on the inner wall of the resin film 131 forming the upper side of the deaerator 13. The female member 25B has a concave tread composed of a pair of claws rising in the width direction on the inner wall of the rain film 132 forming the lower side of the deaerator 13.
  • When the deaerator-carrying compression bag [0053] 2 is used, after the articles 16 to be stored is put in the same manner as the first embodiment and the fastener 12 is stuck to be closed, the nozzle etc. of the deaerating pump is inserted into the inside of the deaerator 13 to discharge the air inside the bag body 10. After sufficiently discharging the air inside the bag body 10 to compress the articles 16, the male member 25A and the female member 25B of the fitting member 25 are fitted to complete the compression work.
  • According to the above-described second embodiment, following advantage as well as the advantages (1) to (5) of the above described first embodiment can be obtained (7) Since the fitting member [0054] 25 is provided in addition to the check-valve structure 15, sealability can be improved by fitting the male member 25A and the female member 25B, so that the compressed condition can be maintained longer than an arrangement solely using the check-valve structure 15.
  • [Modifications][0055]
  • Incidentally, the scope of the present invention is not restricted to the above respective embodiments but includes modification and improvements as long as an object of the present invention can be achieved. For instance, though the resin films [0056] 14A, 14B and 14C constituting the bag body 10 are laminating film of biaxially oriented nylon film (ONY) and linear low-density polyethylene air (LLDPE) film in the above-described embodiments, such arrangement is not restrictive. In other words, various films capable of securing heat weldability and gas barrier odes may be used, which may be laminated film of a combination of other polyolefin resin such as other polypropylene (PP), soft vinyl chloride resin and ethylene-vinyl-acetate copolymer (EVA) resin.
  • The resin films [0057] 131 and 132 of the deaerator 13 may not be LLDPE, but may be various films having heat weldability.
  • Though the check-valve structure [0058] 15 composed of the resin films 131 and 132 is provided inside the deaerator 13 in the above-described embodiments, such arrangement is not restrictive. Various check-valve structures may be used as long as the air inside the bag body can be easily discharged and the outside air can be prevented from flowing into the bag body. For instance, sticky agent may be coated inside the film to improve sealability. Further, the fitting member may be integrally provided outside the deaerator or, alternatively, an independent fitting component may be used for sealing without integrating the deaerator and the fitting member.
  • Though the base end [0059] 13A of the deaerator 13 is welded by the upper seal 11D inside the outer peripheral edge 11 of the bag body 10 in the above-described embodiments, such arrangement is not restrictive. The base end 13A may be welded by the side seal or a bottom seal at the outer peripheral edge.
  • The distal end [0060] 13B of the deaerator 13 may not be located at the position of the respective embodiments, but may be located as desired.
  • Though the check-valve structure [0061] 15 is located around the inside of the base end 13A of the deaerator 13 and the fitting member 25 is located around the distal end 13H of the deaerator 13 in the above described embodiments, such arrangement is not restrictive and the check-valve structure may be provided at any position from the base end to the distal end of the deaerator.
  • INDUSTRIAL AVAILABILITY
  • According to the present invention, since nozzle can be easily drawn out after deaeration and the damage on the deaerator in drawing out the nozzle cal be avoided, the present invention can be suitably applied for a deaerator-carrying compression bag used in compressing and storing bedding, clothes etc. [0062]
