Pouch
Abstract
A pouch has two sheet walls bonded to each other at peripheral
edges thereof. A storage chamber is formed in between the sheet
walls. The storage chamber has a main chamber and a sub-chamber.
The sub-chamber connects to the main chamber and has a smaller size
than the main chamber. A bonding potion is defined at an area on
the pouch beside the sub-chamber. The sheet walls are fastening to
each other at the bonding potion. A guiding line disposes at the
bonding potion extending from the end thereof to the sub-chamber.
The guiding line divides the bonding potion into a first segment
and a second segment. A gap is disposed at the edge of the pouch at
the distal end of the guiding line, whereby user can exert the
first and the second segments of the bonding potion to tear them
apart along the guiding line.

Description
FIELD OF THE INVENTION
[0001] The present invention relates generally to a container, and
more particularly to a sealed pouch which can be torn easily and
smoothly.
BACKGROUND OF THE INVENTION
[0002] Pouches are to contain condiments, shampoos etc. therein.
FIG. 1 shows a conventional sealed pouch 1, which is made of two
plastic films bonded to each other by heat sealing. The pouch 1 has
a storage chamber 2 therein for containing articles. The pouch 1
has a gap 3 at one edge thereof for facilitating user to tear the
pouch 1 to form an opening 4 such that the articles contained in
the pouch can be taken away from the opening 4.
[0003] When tearing the conventional pouch 1, there was an
unexpected and irregular tearing line extended from the gap 3. So
the size of the opening 4 of the pouch 1 is uncontrollable. Beside
that, user had fingers pressing the storage chamber 2 when tearing
the pouch 1, therefore, articles, particularly to liquid materials,
in the storage chamber 2 are easy to be ejected out. These are the
inconveniences of the conventional pouch.
SUMMARY OF THE INVENTION
[0004] The primary object of the present invention is to provide an
improved pouch, which has a smooth and regular tearing line when
tearing the pouch.
[0005] According to the object of the present invention, a pouch
comprises two sheet walls bonded to each other at peripheral edges
thereof. A storage chamber is formed in between the sheet walls.
The storage chamber has a main chamber and a sub-chamber. The
sub-chamber connects to the main chamber and has a smaller size
than the main chamber. A bonding potion is defined at an area on
the pouch beside the sub-chamber. The sheet walls are fastening to
each other at the bonding potion. A guiding line disposes at the
bonding potion extending from the end thereof to the sub-chamber.
The guiding line divides the bonding potion into a first segment
and a second segment, whereby user can exert the first and the
second segments of the bonding potion to tear them apart along the
guiding line.

DETAILED DESCRIPTION OF THE INVENTION
[0016] Please refer to FIGS. 2-5, the first preferred embodiment of
the present invention provides a pouch 10, which has two sheet
walls 11 and 12 overlapped and boned to each other at peripheral
edges thereof. The unbonded part of the pouch 10 defines a storage
chamber 13 between the sheet walls 11 and 12 to store liquid,
colloid, solid or powder articles therein. The sheet walls 11 and
12 are two independent films made of plastic, paper etc. in the
first embodiment, and are bonded to each other by heat sealing as
shown in FIG. 4. The storage chamber 13 of the pouch 10 has a main
chamber 131 and a sub-chamber 132. The sub-chamber 132 is a
channel-like passageway extending from the topside of the main
chamber 131 and has a smaller size than the main chamber 131.
[0017] The pouch 10 has a bonding potion 14 beside the sub-chamber
132 of the storage chamber 13. The bonding potion 14 is an area on
the pouch 10, where the sheet walls 11 and 12 are bonded together.
A guiding line 15 is disposed at the bonding potion 14 extending
from the edge of the pouch 10 to the sub-chamber 132, which is made
from hot pressing the pouch 10 to form a dot line thereon in this
embodiment. The guiding line 15 divides the bonding potion 14 into
a first segment 141, which is closing to the edge of the pouch 10,
and a second segment 142. The distal end of the guiding line 15 has
a gap 16 at the edge of the pouch 10.
[0018] Please refer to FIG. 5, user can hold the first and the
second segments 141 and 142 of the bonding potion 14 of the pouch
10 of the present invention to exert thereon to tear the pouch 10
from the gap 16, the guiding line 15 to the sub-chamber 132. Thus,
the storage chamber 13 has an opening at topside of the sub-chamber
132.
[0019] Hereunder are the advantages of the present invention:
[0020] 1. Easy to tear:
[0021] Because of the guiding line 15 on the bonding potion 14, the
pouch 10 of the present invention is easy to be torn by exerting
the first segment 141.
[0022] 2. The tearing line is regular and smooth:
[0023] When user exerts the first and the second segments 141 and
142 of the bonding potion 14, the stress will concentrate on the
gap 16 and the guiding line 15. So, the tearing line is along the
guiding 15 to be a regular and smooth line.
[0024] 3. Easy to exert for tearing the pouch:
[0025] The bonding potion 14 provides the user a larger area to
hold. Thus, user will not press the storage chamber 13 to make the
articles therein ejecting out when tearing the pouch 10.
[0026] 4. Easy to pour out the articles in the pouch:
[0027] After tearing the pouch 10, the access of the storage
chamber 13 is at the topside of the sub-chamber 132. The size of
the access is fixed for facilitating user to pour out the articles
in the storage chamber 13.
[0028] FIG. 6 shows a pouch 20 of a second preferred embodiment of
the present invention, which has, similar to the first embodiment,
two sheet walls 21 (only shown one sheet wall in FIG.), a storage
chamber 23, a bonding potion 24, a guiding line 25 and a gap 26.
The storage chamber 23 has a main chamber 231 and a sub-chamber
232. The guiding line 25 divides the bonding potion 24 into a first
segment 241 and a second segment 242. Different from the first
embodiment, the sub-chamber 232 has a shape of gradually decreasing
the width thereof from the end connecting to the main chamber 231
to the distal end thereof.
[0029] Please refer to FIG. 7 and FIG. 8, a pouch 30 of a third
preferred embodiment of the present invention is made from bending
an elongated film and to be bonded at the peripheral edge as shown
in FIG. 7. The pouch 30 of the third embodiment has two sheet walls
31 and 32, a storage chamber 33, a bonding potion 34, a guiding
line 35 and a gap 36. The storage chamber 33 has a main chamber 331
and a sub-chamber 332. The guiding line 35 divides the bonding
potion 34 into a first segment 341 and a second segment 342. The
difference is the sub-chamber 332 being an elongated channel-like
passageway at midsection of the topside of the main chamber 331 as
shown in FIG. 8.
[0030] FIG. 9 shows a pouch 40 of a fourth preferred embodiment of
the present invention, which has two sheet walls 41 (only shown one
sheet wall in FIG.), a storage chamber 43, a bonding potion 44, a
guiding line 45 and a gap 46. The storage chamber 43 has a main
chamber 431 and a sub-chamber 432. The guiding line 45 divides the
bonding potion 44 into a first segment 441 and a second segment
442. The difference is the sub-chamber 432 having an inward curved
side closing to the bonding potion 44.
[0031] FIG. 10 shows a pouch 50 of a fifth preferred embodiment of
the present invention, which has two sheet walls 51 (only shown one
sheet wall in FIG.), a storage chamber 53, a bonding potion 54, two
parallel guiding lines 55 and two gaps 56. The storage chamber 53
has a main chamber 531 and a sub-chamber 532. The guiding line 55
divides the bonding potion 54 into a first segment 541 and a second
segment 542. The difference are we providing two guiding lines 55
and two 56 gaps thereon, and providing the sub-chamber 532 having
an outward curved side closing to the bonding potion 54.
