DETAILED DESCRIPTION OF THE PRESENT INVENTION
[0020] Referring to FIG. 1, the inflatable bag for bottles
packaging of the present invention is composed of a plurality of
gas pocket units 10. Each of gas pocket units 10 consist of a main
gas pocket 11 having larger width and an auxiliary gas pocket 12
having smaller width. Welding line 31 sat between main gas pocket
11 and auxiliary gas pocket 12. Conduits 30 are installed along
welding lines 31 by distance of 10.about.15 centimeters, such that
gas in the main gas pockets 11 and auxiliary gas pocket 12 can be
flowed through conduits 30. However, gas pocket unit 10 is side by
side with another, and welding line 32 is located in between, and
there are no conduits installed on said welding line 32. The gas
pocket units 10 are isolated between each and gas can not flow
between each other. Thereby, when any main gas pockets 11 or
auxiliary gas pockets 12 is broken, gas in which have left out, the
other gas pockets still keep gas in it own. There is a gas inlet 2
on side of the inflatable bag for bottles packaging 1, a gas
channel 14 extend from the gas inlet 2 and is connecting to each of
main and auxiliary gas pockets 11,12, and gas can be entered though
the gas channel 14. When the inflatable bag for bottles packaging 1
is charged with gas from the gas inlet 2, gas will go along the gas
channel 14 and enters each of main and auxiliary gas pockets 11, 12
and inflates them.
[0021] Referring to FIGS. 1, 2 and 3, the FIG. 2 shows the reverse
side of the inflatable bag for bottles packaging 1 when it is
uncharged with gas, and the FIG. 3 illustrates a sectional view
including the obverse and reverse side of the inflatable bag for
bottles packaging 1 along line 3-3 shown in FIG. 1. The inflatable
bag for bottles packaging 1 is composed of two films, upper film 21
and lower film 22, both of which are made of plastic or similar
materials. The periphery of said films is pressed welding along
line 35 by high temperature, which seal up the inflatable bag for
bottles packaging 1 and prevent gas from escape. The check valves
of the gas pockets are composed of two films, upper valve film 25
and lower valve film 26, which are of appropriate length and placed
between upper and lower films 21, 22. Welding lines 31, 32, 35 are
formed by binding upper and lower films 21,22 and upper and lower
valve films 25,26 together using hot press. And an anti-welding
layer 33 located near gas channel 14 is placed between upper and
lower valve films 25, 26. It is to avoid upper and lower valve
films 25, 26 binding together while the welding line 36 is formed
by hot press. The welding line 36 located at the pocket inlet 45 of
the gas pocket units 10 is formed by hot pressing on films 21, 22,
25 and 26. In this way, said anti-welding layer 33 allow gas
charging though upper and lower valve films 25, 26 at pocket inlet
45 found in each main and auxiliary gas pockets 11,12. Still
Referring to FIG. 1, there are gas guiding welding spots 34 on the
upper and lower valve films 25, 26. They are formed by binding
upper film 21, upper valve film 25 and lower valve film 26 together
using hot press. The upper and lower valve films 25, 26,
anti-welding layer 33 and gas guiding welding spots 34 together act
as check valves, which be able to seal the pocket inlet 45 of each
gas pocket units 10 when the inflatable bag for bottles packaging 1
is charged with gas, and making gas pocket units 10 gastight after
charging.
[0022] Further, folding lines 41, 42, 43, 44 located appropriately
at each main and auxiliary gas pocket 11, 12, allow automatic
bending of each main and auxiliary gas pockets 11, 12 when the bag
is charged with gas. Referring to FIGS. 1 and 2, successive folding
along 35, 41, 42, 43 and 44 will form a closed envelope to protect
bottles article inside against impact from any direction.
[0023] Referring again to FIGS. 1 and 2, the inflatable bag for
bottles packaging 1 of the present invention equipped with one pair
of connecting unit 60 which locate at each edge of predetermined
set of main and auxiliary gas pocket 11, 12. The connecting unit 60
consists of vertical welding line 61 and horizontal welding line 62
which forms H configuration by hot pressing the upper and lower
film 21, 22. The connecting unit 60 is completed by cutting out the
outer part to form U shape breach 63.
[0024] Referring to FIG. 4, when the inflatable bag for bottles
packaging 1 is charged through the gas inlet 2 with gas, the gas
will go along the gas channel 14 and enter each of main and
auxiliary gas pockets 11, 12. Said gas guiding welding spots 34
allow gas entering main and auxiliary gas pockets 11, 12 easily.
Referring to FIGS. 5 and 6, which illustrate a sectional view of
charged main and auxiliary gas pockets 11, 12 along line 5-5 shown
in FIG. 3. After charging, the upper valve film 25 and the lower
valve film 26 will be pressed tightly toward upper film 21 by high
pressure in main and auxiliary gas pockets 11, 12. The gas guiding
welding spots 34 bind upper film 21, upper valve film 25 and lower
valve film 26 together by hot press. Therefore upper and lower
valve films 25, 26 will be pressed toward upper film 21 instead of
the lower film 22. The upper and lower valve films 25, 26, and
upper film 21 are made of plastic or similar film materials, which
will close pocket inlet 45 and gastight each main and auxiliary gas
pockets 11, 12 while upper and lower valve films 25,26 are pressed
toward upper film 21. Thereby, the main and auxiliary gas pockets
11,12 contain gas, and the welding spots 34 assist gastight
effect.
[0025] Referring to FIG. 7, showing an inflated bag for bottles
packaging 1 in which all gas pocket unit 10 are inflated and bended
along 41, 42, 43 and 44 and form 3 dimensional pockets. Due to the
stress relief effect of the U shape breach 63 on connecting unit
60, the outer part beyond the bending spots 41, 42, 43, and 44 of
gas pocket unit 10 forms top and bottom sides of the two
neighboring cylindrical containers which is connected by connecting
unit 60 and are suitable for protecting cylindrical bottles or cans
from mechanical impact. After inflation, gas channel 14 does not
contain pressurized gas, and is always flattened. Bottle is put
into cylindrical space through opening 50, and the flattened gas
channel 14 is used as cover for opening 50. Connecting unit 60 also
acts as connector for cylindrical containers to facilitate
handling. Every gas pocket unit 10 is isolated by welding line 32,
therefore the rest of gas pocket unit 10 remain pressurized when
one or some of gas pocket unit 10 is broken and flattened. The
protection function of inflated bag for bottles packaging 1 is
therefore retained even if one or some of gas pocket unit 10 was
broken and flattened.
[0026] The previous embodiment consists of one pair of connecting
unit 60 locating on each edge of specific set of main and auxiliary
gas pocket 11, 12. It connects two set of cylindrical container
form by inflated gas pocket units 10 on each side. By same
principle, two or more pairs of connecting unit 60 may be
constructed on predetermined set of gas pocket units 10 and making
three or more cylindrical spaces for bottles. One of the
embodiments is demonstrated in FIG. 8, which showing the front view
of an uncharged inflated bag for bottles packaging 1 having two
pairs of connecting unit 60. FIG. 9 showing the perspective view of
the same embodiment inflated and forming three cylindrical spaces
for bottles. Another possible embodiment having gas pocket units 10
which consists of only one gas pocket (only main gas pocket 11) is
also able to form plural cylindrical spaces for bottles with the
aid of said connecting unit 60.
[0027] While the invention has been described with referencing to
preferred embodiments thereof, it is to be understood that
modifications or variations may be easily made without departing
from the spirit of this invention, which is defined by the appended
claims.
