Description
TECHNICAL FIELD
[0001] 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.
BACKGROUND ART
[0002] 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.
[0003] 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.
[0004] 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.
DISCLOSURE OF THE INVENTION
[0005] 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.
[0006] 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.
[0007] 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.
[0008] 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.
[0009] 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.
[0010] 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.
[0011] 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.
[0012] In the present invention, the deaerator may preferably be
located approximately at the center of the bag body.
[0013] 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.
[0014] In the present invention, the back-flow preventing means of
the present invention may preferably include a check-valve
structure.
[0015] 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.
[0016] 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.
[0017] 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.
[0018] 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.
[0019] 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.
[0020] 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.

BEST MODE FOR CARRYING OUT THE INVENTION
[0026] Embodiments of the present invention will be described below
with reference to attached drawings.
[0027] [First Embodiment]
[0028] FIGS. 1 to 4 illustrate a deaerator compression bag 1
according to first embodiment of the present invention
[0029] The deaerator carrying compression bag 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.
[0030] The bag body 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.
[0031] Further, a base end 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.
[0032] In the above, the respective resin films 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).
[0033] As shown in FIGS. 1 and 2, the deaerator 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.
[0034] Incidentally, the material of the resin films 131 and 132
forming the deaerator 13 may be, for instance, LLDPE.
[0035] As shown in FIGS. 2 and 4, the fastener 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.
[0036] The concave tread 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.
[0037] The material of the fastener 12 may be, for instance, the
above-described LLDPE.
[0038] Thus constructed deaerator-carrying compression bag 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.
[0039] During the deaerating process, by inserting the nozzle of
the deaerating pump, the resin films 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.
[0040] The opening of the deaerator 13 may be shut with a fitting
member etc. for keeping the sealed condition for a long time.
[0041] According to the above first embodiment, following effects
can be obtained
[0042] (1) The deaerator 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.
[0043] (2) Since it is not necessary to insert the nozzle of the
deaerating pump deep into the bag body 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.
[0044] (3) Since the base end 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.
[0045] (4) Since the check-valve structure 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.
[0046] (5) Since the check-valve structure 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.
[0047] (6) Since the check-valve structure 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.
[0048] [Second Embodiment]
[0049] FIG. 5 shows a deaerator-carrying compression bag 2
according to second embodiment of the present invention.
[0050] 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.
[0051] The deaerator-carrying compression bag 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.
[0052] The fitting member 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.
[0053] When the deaerator-carrying compression bag 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.
[0054] 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 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.
[0055] [Modifications]
[0056] 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
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.
[0057] The resin films 131 and 132 of the deaerator 13 may not be
LLDPE, but may be various films having heat weldability.
[0058] Though the check-valve structure 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.
[0059] Though the base end 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.
[0060] The distal end 13B of the deaerator 13 may not be located at
the position of the respective embodiments, but may be located as
desired.
[0061] Though the check-valve structure 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
[0062] 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.
