Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to a shockproof packing bag,
particularly to one including an upper bag body and a lower bag
body combined together and formed with an accommodating chamber
therebetween. The upper and the lower bag body are respectively
provided with an inner layer and an outer layer, which have their
peripheral edges combined together by thermal fusing to form the
upper and the lower bag body. Further, the upper and the lower bag
body have their peripheral edges attached with a zipper, and
between the inner layer and the outer layer is formed an air
chamber. Further, the upper and the lower bag body have one lateral
side combined together by thermal fusing to form a compression side
having an air tap fitted therein. Thus, after inflated, the packing
bag is formed with a plurality of air bags for wrapping up and
positioning the articles placed in the interior, having effect of
shock prevention, usable repeatedly and highly effective for
environmental protection.
[0003] 2. Description of the Prior Art
[0004] Conventionally, to prevent brittle or expensive articles
packed in boxes from damaged in bumping when they are transported,
one way is to use paperboard and corrugated paperboard for
separating and positioning stably the articles in the boxes, but
actually the articles packed in the box cannot be effectively kept
fixed in position. Another way is to stuff shockproof material into
the boxes, such as sponge, foamed materials, expanded polystyrene
and the like, for wrapping and positioning the articles placed
therein. However, such shockproof packing materials cannot be used
repeatedly, nor can they decompose themselves, seriously pollute
the environment.
SUMMARY OF THE INVENTION
[0005] This invention has been devised to offer a shockproof
packing bag able to completely wrap up articles and form an air
bag, having excellent effect of shock prevention, able to form a
plurality of air bags after inflated for wrapping and positioning
articles placed therein, having excellent effect of shock
prevention, able to be used repeatedly and conforming to
environmental protection.
[0006] The shockproof packing bag in the present invention includes
an upper bag body and a lower bag body combined together and formed
with an accommodating chamber therebetween. The upper and the lower
bag body are respectively provided with an inner layer and an outer
layer, which have their peripheral edges combined together by
thermal fusing to form the upper and the lower bag body. The upper
and the lower bag body have their peripheral edges attached with a
zipper, and between the inner layer and the outer layer is formed
an air chamber. Further, the upper and the lower bag body have one
lateral side combined together by thermal fusing to form a
compression side having an air tap fitted therein.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0015] A preferred embodiment of a shockproof packing bag 1 in the
present invention, as shown in FIGS. 1, 2 and 3, includes an upper
bag body 11 and a lower bag body 12 combined together and formed
with an accommodating chamber therebetween.
[0016] The upper bag body 11 and the lower bag body 12 are
respectively provided with an inner layer 111, 121 and an outer
layer 112, 122, which have their peripheral edges 113, 123
respectively combined together by thermal fusing to form the upper
and the lower bag body 11 and 12. The upper and the lower bag body
11, 12 have their peripheral edges 113, 123 attached with a zipper
2 that is composed of a male zipper member 21 and a female zipper
member 22 respectively combined by thermal fusing with the
peripheral edge 113 of the upper bag body 11 and with the
peripheral edge 123 of the lower bag body 12. The upper and the
lower bag body 11 and 12 respectively have a plurality of
compressed points 114 and 124 provided between the inner layer 111,
121 and the outer layer 112, 122 so as to form plural air chambers
115, 125 therebetween. The upper and the lower bag body 11 and 12
have one lateral side combined together by thermal fusing to form a
compressed side 13 having an air tap 14 fitted in the center. The
air tap 14 is formed by compressing the opposite sides of the
intermediate portion of two soft films, having an insert slot 140
in the center. The outer ends 141 of the two films, which are not
compressed together, has one film formed with an oblique cut
surface 142. An inner end 143 of the air tap 14 is not compressed,
and an inner opening 144 of the insert slot 140 is formed shrinking
gradually.
[0017] In using, as shown in FIGS. 1 to 4, firstly, if articles 3
to be packed are formed with sharp ends, they had better be wrapped
up by protective material so as not to pierce the packing bag 1.
Next, pull open the zipper 2 and place the articles 3 in the
accommodating chamber 10 between the upper and the lower bag body
11, 12 and then pull and close the zipper 2, letting the male
zipper member 21 and the female zipper member 22 engaged with each
other. Subsequently, slightly press the opposite sides of the air
tap 14 in the compression side 13 with fingers to make the insert
slot 140 of the air tap 14 a little opened and then insert the
inflating nozzle 4 into the insert slot 140 of the air tap 14,
letting the tip of the inflating nozzle 4 inserted through the
inner opening 144 of the insert slot 140 to prop open the inner end
143 of the air tap 14, as shown in FIGS. 5, 6 and 7.
[0018] Then, air is injected into the air chamber 115, 125 of the
upper and the lower bag body 11, 12 through the air tap 14, letting
the air chambers 115, 125 filled with air and distended. Since the
air chamber 115, 125 of the upper and the lower bag body 11, 12 are
respectively provided with several compressed points 114, 124;
therefore, the upper and the lower bag body 11, 12 are formed with
a plurality of air bags for performing buffering and shock
prevention, as shown in FIG. 4. After the air chambers 115, 125 of
the upper and the lower bag body 11, 12 are fully filled with air,
the outward expansion force of the air will be stopped by the
zipper 2 on the outer peripheral edge of the upper and the lower
bag body 11, 12 and transferred to the interior of the bag body to
push the inner layers 111, 121 of the upper and the lower bag body
11, 12 to move inward and forcefully wrap up the articles 3 in the
accommodating chamber 10 and fix them in position.
[0019] Lastly, remove the inflating nozzle 4 out of the insert slot
140, letting the air tap 14 of the packing bag 1 recover its thin
and flat shape. At this time, the two films at the inner end 143 of
the air tap 14, will be closely pressed together by the inner
pressure of the air chambers 115, 125, which is higher than the
outer pressure, to prevent the air inside the air chambers 115, 125
from leaking out through the air tap 14. Another method for
avoiding leaking of the inner air is to have the outer end of the
air tap 14 bent and rolled up and then glued by means of non-drying
adhesive tape.
[0020] By so designing, the air chambers 115, 125 can be kept in an
inflated condition, impossible to cause leaking, and the articles 3
in the packing bag 1 can be completely wrapped up for protection
and also the air bags of the air chambers 115, 125 enable the
packing bag 1 to achieve effects of buffering and shock prevention
to avoid the articles 3 to be damaged in bumping. To collapse the
packing bag 1 for storing after it is used, only slightly press the
opposite sides of the air tap 14 with fingers to slightly prop open
the insert slot 140 of the air tap 14 and the inner end 143 for
exhausting out the air in the air chambers 115, 125. To sum up, the
packing bag of this invention is able to be stored with less space,
usable repeatedly, and highly effectively in environmental
protection and elevating economic gain.
[0021] While the preferred embodiment of the invention has been
described above, it will be recognized and understood that various
modifications may be made therein and the appended claims are
intended to cover all such modifications that may fall within the
spirit and scope of the invention.
