Description

DESCRIPTION
POUCH CONTAINER FOR LIQUID MATERIAL
TECHNICAL FIELD
The present invention relates to a pouch container for liquid
material and, more particularly, to a container that is designed to
securely maintain its self-standing force even when depressing force is
applied to an associated pump dispenser.
In addition, the present invention further relates to a pouch
container for liquid material that is designed to be foldable in a compact
state when there is no content therein and to be improved in its design
and outer appearance.
BACKGROUND ART
Generally, liquid contents such as detergent, cleaning material,
and medicinal liquid are packaged, delivered and sold in a state where
they are contained in a variety of containers.
The pouch container is formed in a variety of shapes. To drink
the contents contained in the pouch container, the user opens the
container by cutting a portion of a seal portion or putting a straw through
the container. For example, Korean Utility Model No. iyyi-b /4U discloses a
container for liquid material that is designed for the user to dispense and
suck the liquid content contained in the container.
Such a container has a lightweight and is flexible to make it
convenient to handle the same. However, since the container should
maintain its predetermined shape, there is a limitation in reducing the
volume thereof, because of which it is inconvenient in custody and
delivery.
That is, such containers are classified into a standing pouch, an
M-type pouch and a trihedron pouch.
The standing pouch is designed having a foldable bottom so that
it can be folded or unfolded as occasion demand. However, it is a
simple vertical self-standing type, a specific shape cannot realized.
The M-type pouch has M-shaped both sides that is folded and
unfolded. This is also a vertical type without any specific shape.
The trihedron pouch has a problem that it cannot smoothly be
folded.
SUMMARY OF THE INVENTION
Therefore, the present invention has made in an effort to solve the above-described problems.
It is an objective of the present invention to provide a pouch
container for liquid material, which is designed to securely maintain its
self-standing force even when depressing force is applied to an
associated pump dispenser.
It is another objective of the present invention to provide a pouch
container for liquid material, which is designed to be foldable in a
compact state when there is no content therein and to be improved in its
design and outer appearance.
To achieve the above objectives, the present invention provides
a pouch container for liquid material, comprising a side-top portion; and
a bottom portion defining a trihedron body with the side -top portion
when the liquid material is filled in the body, wherein the side-top
portion and the bottom portion are sealed by a vertical seal portion
sealing a first side end of the side-top portion and a horizontal seal
portion sealing a second side end with a first side end of the bottom
portion, the side-top portion is provided at its top with a top folding line
by which the side-top portion can be folded in two layers when the liquid
material is not filled in the container, the top folding line connecting an upper end of the vertical seal portion to the horizontal seal portion, and
the bottom portion is provided with a central folding line by which the
bottom portion can be folded into two layers inward the folded side-top
when the liquid material is not filled in the container, the central folding
line connecting a lower portion of the vertical seal portion to the
horizontal seal portion.
The side-top portion is provided with a liquid outlet that is
defined by a cutting line or a cutting groove or by unsealing a portion of
the vertical seal portion. The side-top portion is folded along the top
folding line, both side ends of the side-top portion are different in their
lengths.
The vertical seal portion is disposed at an angle of 20- 160
degree with respect to the bottom portion, and the bottom folding line of
the bottom portion has a first end contacting a mid-point of the
horizontal seal portion.
The bottom folding line has a second end contacting a lower end
of the vertical seal portion. The second end of the bottom folding line is
formed at a predetermined height from the lower end of the vertical seal
portion so that the vertical seal portion can be branched into two seal portions to the lower end thereof. The branched seal portions are
widened from each other when the liquid material is filled in the
container.
The seal portion between the side-top portion and the bottom
portion is extended in three ways. The branched seal portions are not
widened away from each when the liquid material is filled in the
container.
The bottom portion is widened as it goes from the first end to the
second end of the bottom folding line in a streamline-shape. The top
folding line and/or the bottom folding line are formed by seals.
When the liquid material is filled in the container, the outer shape
defined by the side-top and bottom portions has a streamlined
trihedron-shape. The side-top and bottom portions are folded to be
flat when the liquid material is not filled in the container.
The bottom portion is designed to be widened from a point to a
rear end to improve the standing ability of the container, and the top
folding line has a first end contacting the vertical seal portion and a
second end contacting the horizontal seal portion. The first end contacts
an upper end of the vertical seal portion. The second end contacts a mid-point of the horizontal seal portion.
The first end contacts the upper end of the vertical seal portion.
The side-top and bottom portions may be integrally formed.
The folding line is formed to be horizontal or inclined or is
arc-shaped.
When the liquid material is filled in the container, the width of the
container is reduced as it goes from the bottom portion to the top portion.
The side-top and bottom portions are formed of synthetic resin film.
The film is multi-layered. The side-top and bottom portions are
formed of carton.
The side-top portion may be formed of synthetic resin, and the
bottom portion is formed of carton.
Alternatively, the side-top portion may be formed of carton, and
the bottom portion is formed of synthetic resin.
The lateral length of the side-top portion is less than the
longitudinal length of the side-top portion.
The side-top portion has a narrow top and a wide bottom. The
pouch container may further comprise outlet means. The outlet means
is formed to be horizontal or inclined. The outlet means comprises a spout member. The outlet means further comprises a cap coupled on
the spout member. The spout member further comprises a spout guide
member extending inside the container. The spout guide member is
disposed at a position where the folding of the side-top and bottom
portion is not disturbed.
Alternatively, the outlet means comprises a pump dispenser. The
pouch container may further comprise self-standing support means
disposed between the pump dispenser and the bottom portion so that the
container can maintain the self- standing force even when the pump
dispenser is depressed.
The self-standing support means comprises a spout tube
assembled on an outlet of a lower housing of the pump dispenser, the
spout tube being provided with a spout hole.
Alternatively, the self-standing support means extends from the
pump dispenser to the bottom portion.
The pouch container may further comprise a vacuum
absorption-preventing member is formed on one of the side-top and
bottom portions.
According to another aspect, the present invention provides a method for manufacturing a pouch container, comprising the steps of
preparing a rectangular film; forming a lateral center folding line and
sub-folding lines on both side of the lateral center folding line, the
sub-folding lines being inclined with respect to the lateral center folding
line and symmetrical to each other on the basis of the center folding line;
folding the film along the folding lines, the sub-folding lines and the
central folding line have folding directions opposite to each other; and
sealing the folded surfaces of the film such that a portion of the film,
which is defined between the center folding line and the sub-folding
lines, can be a bottom portion of the container, and portion of the film,
which are defined on outer portions of the sub-folding lines, can be a
side-top portion of the container.
Preferably, the sub-folding lines can be formed by a sealing
process. An outlet portion is formed on the side-top portion. The
outlet portion is defined by a cutting-line or a cutting groove.

BEST MODE FOR CARRYING OUT THE INVENTION
Preferred embodiments of the present invention will be
described more in detail hereinafter in conjunction with the
accompanying drawings.
Embodiment 1
FIGS. 1 and 2 show an embodiment of the present invention.
As shown in the drawings, the inventive pouch container 1 for
liquid material is designed such that it has a trihedron or streamed
trihedron shape when liquid content is filled therein (see FIG. 1) and has
a flat shape when liquid content is not filled therein (see FIG. 2).
That is, the pouch container 1 for liquid material has a side-top
portion 100 and a bottom portion 200. A peripheral portion where the
side-top and bottom portions 100 and 200 contact each other is sealed.
That is, both side ends of the pouch container 1 are defined by horizontal and vertical seal portions 101 and 102 that are disposed in a crossing
direction with respect to each other. The side-top portion 100 and the
bottom portion 200 are divided into two surfaces by folding lines 104
and 201, respectively. That is, the side-top portion 100 and the bottom
portion 200 are folded along the folding lines 104 and 210 when the
liquid material is not filled therein. The folding line 201 is extended to
connect the horizontal and vertical seal portions 101 and 102 to each
other.
The side-top portion 100 is formed in a predetermined shape
determining a volume of the container. The side-top portion 100 and
the bottom portion 200 can be integrally formed without any seal
portion.
As the side ends of the side-top portion 100 are formed of the
seal portions 101 and 102 disposed in a crossing direction with respect
to each other, the container can maintain its self-standing force when
the content is filled therein.
The bottom portion 200 is formed in a triangular shape or a
streamlined shape.
As shown in FIGS. 3 and 4, in the pouch container 1, the folding line 104 is formed along a centerline of the side-top portion 100 and the
folding line 201 is formed along a centerline of the bottom portion 200.
Although the folding lines 104 and 201 can be omitted, they are
necessary to easily manufacture the container.
The folding line 201 on the bottom portion 200 has a first end
contacting a mid-point of the seal portion 101 and a second end
contacting a lower end of the seal portion 102. In addition, the second
end of the folding line can be further extended into the seal portion 102
so that branched seal portions can be formed under the vertical seal
portion 102.
Furthermore, the folding line 104 is also formed such that it can
connect the seal portions 101 and 102 to each other. That is, the
folding line 104 has a first end contacting the mid-point of the seal
portion 101 and a second end contacting an upper end of the seal portion
102.
In the above-described container 1, an outlet through which the
content can be poured is formed. Such an outlet is generally marked
with a cutting line 105 and a cutting notch 106 formed on the seal
portion. Alternatively, the folding line 104 of the side-top portion 1DU can
be processed with a seal portion.
As shown in FIG. 5, the container can be formed in a variety of
shapes by varying the lengths 1 and L.
The container can be further formed in a variety of shapes by
varying angles a and A of the seal portions 101 and 102 with respect to
the bottom portion 2002. The angles can be varied in a range from
20-160 degrees.
As shown in FIG. 6, a bottom contacting area of the bottom
portion 200 can be adjusted by adjusting a length B of the horizontal seal
portion 101 of the bottom portion 200 when it is folded along the folding
line 201 of the bottom portion.
FIG. 7 shows another embodiment of the present invention. In
this embodiment, an example for adjusting the length of the horizontal
seal portion 101 is illustrated. That is, a predetermined area b' within
the range of the length B of the folded horizontal seal portion 101 is
attached to adjust the bottom contacting area of the bottom portion.
That is, when the predetermined area b' is not attached, the
bottom portion 200 is unfolded on the basis of the folding line 201 as long as the length of the horizontal seal portion. However, wnen me
predetermined area b' is attached, the bottom portion 200 is unfolded on
the basis of the attached portion. The reason why the predetermined
portion is attached is to prevent the folding portion of the horizontal seal
portion from being damaged.
FIGS. 8 and 9 shows varied examples of the pouch container of
the present invention. In these examples, the horizontal and vertical
seal portions are formed such that extended lines thereof are meet to
each other when the container is folded.
FIG. 10 shows a structure of the pouch container for filling liquid
material therein. As shown in the drawing, a portion of the vertical seal
portion is left as an unsealed portion 107. The liquid material is filled
through the unsealed portion 107 and then the unsealed portion 107 is
sealed.
FIG. 11 shows another embodiment of the present invention. In
this embodiment, a second horizontal seal portion that is extended from
the vertical seal portion 102 when the bottom portion 200 is folded is
further formed on the bottom portion 200. In addition, when the bottom
portion 200 is folded, the folded second horizontal seal portion are attached at a predetermined portion B' within a range of the length of the
folded second horizontal seal portion.
In this case, when the liquid material is filled in the container,
since the folding line 201 of the bottom portion 200, which is in the
vicinity of the seal portion 102, is lowered, the area of the bottom
portion 200, which contacts the outer flower, is increased.
That is, since one side end of the bottom portion is wider than the
other side end, the self-standing force can be further enhanced.
At this point, the vertical seal portion 102 and the second
horizontal seal portion is diverged in three ways when the liquid material
is filled in the container and a point from which the seal portions are
diverged is located at a predetermined height.
In addition, in accordance with a sealing angle of the seal portions
101 and 102, the container 1 can be designed in a variety of shapes.
In addition, when the seal portion of the bottom portion 200 is
formed inward the side-top portion 100, a portion between the lower
end of the seal portion 102 and the folding line 201 of the bottom 200 is
not widened, whereby the self-standing force can be enhanced. At this
point, the bottom portion 200 is formed in a triangular shape or a development shape on the basis of the folding line 2U1 curved inwardly.
Furthermore, the container 1 may be formed of synthetic resin
film or carton. When it is formed of synthetic resin film, it is preferable
that the film is a multi-layered film, and when it is formed of carton, it is
preferable that the carton is coated.
Furthermore, it is also possible, the side-top portion 100 is
formed of synthetic resin film and the bottom portion 200 is formed of
carton or vice versa.
As described above, as a width of the container is less than a
length of the container, the standing stability of the container can be
further improved. In addition, as a width and length of the container is
increased as it goes downward, the standing stability can be further
improved.
Embodiment 2
In this embodiment, specially prepared dispensing means is
associated with the pouch container 1 described in the above
embodiment to easily dispense the contents out of the container.
For example, FIGS. 12 and 13 show an example where a pump
dispenser 300 is assembled on an outlet of the pouch container 1. Describing more in detail, after defining an outlet by cutting a
portion of the side-top portion 100 of the pouch container 1, an outlet
member 400 is attached on the outlet, defining a seal portion 108. Then,
the liquid content is filled in the container 1 through the outlet member
400 and the pump dispenser 300 is associated with the outlet member
400.
The outlet member 400 can be disposed in a horizontal direction
or with a predetermined inclined angle.
In addition, to prevent the pouch container 1 from being collapsed
and folded when depressing force is applied to a button 301 of the pump
dispenser, self-standing supporting means is associated with a bottom
of the pump dispenser 300.
The self-standing supporting means comprises a rigid spout tube
302 mounted on an outlet of the lower housing of the pump dispenser
300. A spout hole 303 is provided on the spout tube 300.
The spout tube 302 is designed having a length by which it is
extended to the bottom 200 of the container when the pump dispenser
300 is coupled on the outlet member 400. The spout tube 302 is
provided at its lower end with more than one bottom communication hole 303. The spout tube 302 is further provided at its lower end with a
wide support contacting the bottom portion 200 of the container 1 to
prevent the bottom portion 200 from being damaged while enhancing the
supporting force. The wide support can be integrally or separately
formed with or from the spout tube.
Alternatively, a specially prepared protecting member can be
formed on a portion of the bottom portion 200, where the lower end of
the spout tube 302 contacts.
As shown in FIGS. 14 and 15, the self-standing supporting means
may further comprises an reinforcing support 304 extending from the
pump dispenser 300 to the bottom portion 200. The reinforcing
member 304 is preferably disposed on the both sides of the folding line
201 in an identical proportion so that it does not disturb the folding
operation when the bottom portion 200 is folded on the basis of the
folding line 201.
The reinforcing support 304 extends from the lower end of the
outlet member 400 to the bottom portion 200.
As shown in FIG. 16, the self-standing supporting means may
further comprise a support plate 305 formed on the bottom portion 200 of the pouch container 1. The support plate 305 is formed on a portion
of the bottom portion 200, where the lower end of the spout tube 302 is
located. The support plate 305 is designed to be folded when the
bottom portion 200 is folded along the folding line 201. Reinforcing
projections can be further formed on the support plate 205 to enhance
the rigidity of the support plate 205.
The use of the pouch container 1 will be described hereinafter.
When the button 301 of the pump dispenser 300 is depressed for
the pumping operating, the liquid contents is dispensed out of a housing
of the pump dispenser.
For the above operation, a piston rod is provided in the housing to
generate vacuum pressure as it vertically operates. The piston rod is
provided with a pouring passage communicating with a pouring hole of
the button 301. The piston rod is provided at its upper end with a
pumping stem through which the liquid content is poured. Since such a
structure of the pump dispenser is a well-known conventional art, the
detailed description thereof will be omitted herein.
During the pumping operation, the depressing force is applied to
the pouch container 1. At this point, since the self-standing supporting means is provided, the side-top portion 100 of the pouch container is not
folded, maintaining its configuration.
That is, the spout tube 302 prevents the side-top portion 100
from being compressed. In addition, by the pumping operation, the
content in the pouch container 1 is poured through the pouring hole
formed in the button 301 via the spouting hole 303 formed on the lower
end of the spout tube 302.
In addition, FIG. 17 shows another example of the pouch
container that is designed having the more stable standing structure. A
length B of the seal portion of the bottom portion 200 is further
increased and the seal portion between the side-top portion 100 and the
bottom portion 200 is designed to be branched in three ways and to be
unfolded when the liquid content is filled therein. At this point, the
longer the length of the seal portion of the bottom portion 200, which
contacts the folding line 201, more the area of the bottom portion 200,
which contacts the outer surface.
As shown in FIG. 18, a handle 500 can be further assembled on
the side-top portion 100 of the pouch container so that it is easier to
handle the container. As another example, FIG. 19 shows a pouch container with a
spout assembly 600 assembled on an outlet.
The spout assembly 600 is provided to make it possible for a user
to suck or dispense the liquid content to another container. The spout
assembly 600 includes a spout guide 601, an upper side of which a
spouting hole 602 is formed.
FIGS. 20 and 21 show a variety of examples for assembly
location of the spout assembly 600 on the pouch container. An outlet of
the pouch container 1, on which the spout assembly is assembled, can be
formed horizontally or at a predetermined inclination. The outlet of the
pouch container 1 is formed by cutting the seal portion.
Such a spout assembly can be associated with a one-touch
opening cap 600' or a screw-type cap 603 as shown in FIGS. 22 and 23.
As shown in FIG. 23, the spout assembly 600 with a cap 600' or
603 can be covered by a cover 117 to prevent the spout assembly 600
from being polluted.
FIG. 24 shows an modified example of the pouch container, in
which a vacuum sticking preventing portion 118 is formed on at an inner
surface of one of the side-top and bottom portions of the pouch container 1. The vacuum sticking preventing portion 118 can be
formed in a variety of shape such as concaved and convexed member or
or plural projection point.
Embodiment 3
FIGS. 25 to 28 shows an embodiment illustrating an example for
forming the pouch container using a single film.
FIG. 26 is a development view of the pouch container 1, and FIG.
25 shows a state the pouch container is firstly folded.
As shown in FIG. 26, on a rectangular pouch film, a central folding
line 108 is first formed, and sub-folding lines 109 are formed on both
side of the central folding line 108 in a symmetrical structure. The
spaces between the central folding line 108 and the sub-folding liens
109 define the bottom portion 200. The sub-folding lines 109 are
inclined with respect to the central folding line 108 at a predetermined
angle.
Outer surfaces with respect to the sub-folding lines 109 defines
the side-top portion 100 of the container. After folding the sub-folding
lines 109, upper, left, and right ends are sealed as shown in FIG. 27, thereby forming the seal portions 110, 111, 112 and 113.
From a state of FIG. 27, by cutting the needless periphery portion
of the folded container, the finalized pouch container is obtained as
shown in FIG. 28.
INDUSTRIAL APPLICABILITY
As described above, the pouch container of the present invention
is designed to be stable in its standing ability.
The pouch container is further designed to maintain its
self-standing force even when an associated pump dispenser is
depressed.
Since the pouch container is flexible, the delivery costs can be
saved as it can be delivered in a state where it is folded to be compact
state.
Furthermore, since the pouch container can be foldable, the
delivery costs can be further saved when it is delivered in a
semi-product state.
In addition, since the both side ends seal portions are formed in a
crossing direction with respect to each other, the outer appearance can be further improved. That is, a variety of animal shape can be realized
according to the sealing and cutting method, improving the sales
promotion for the products using the pouch container of this invention.
