Description

POUCH CONTAINER WITH SPOUT ASSEMBLY AND METHOD FOR

MAKING THE SAME

The present invention relates to a pouch container with a spout

assembly and a method for making the same.

BACKGROUND ART

Generally, a pouch container is opened by a cutting tool so that

the user can use the contents contained therein. In recent years, a

spout assembly is associated with the pouch container to easily

discharge the contents through the spout assembly.

When the spout assembly is used, there is a need to hygienically

protect the spout portion of the spout assembly. However, no

development for this solution has been proposed. SUMMARY OF THE INVENTION

Therefore, the present invention has made in an effort to solve

the above-described problems of the conventional art. It is an

objective of the present invention to provide a pouch container that can

hygienically protect a spout portion of a spout assembly and a method

for making such a pouch container.

To achieve the above objective, the present invention provides a

pouch container comprising a main body formed by front and rear films

attached to each other to define a bag,' a spout assembly attached on an

end of the main body to dispense contents contained in the main body;

and a gusset portion formed by extending from one of the front and rear

films and by being folded, a bottom of the pouch container being

remained as an unsealed portion through which contents can be filled in

the pouch container.

The unsealed portion is sealed after the contents are filled in the

pouch container.

The spout assembly is covered by a cover extending from the main

body with a cutting line formed between the cover and the main body.

The gusset portion is formed by a separated film. According to another aspect of the present invention, there is

provided a pouch container comprising a main body; a spout assembly

attached on one end of the main body; and a cover extending from the

main body to cover the spout assembly, wherein a first portion of the main

body, which is opposite a second portion where the spout assembly is

attached is remained as an unsealed portion, the unsealed portion is

sealed in a perpendicular direction of the second portion after contents are

filled in the main body through the unsealed portion.

According to still another aspect of the present invention, there is

provided a method for pouch container with a spout assembly, comprising

the steps of forming a main body by releasing films from a roll of film;

forming a cutting line on the main body; locating the spout assembly on

the main body such that an attaching portion of the spout assembly is

located right under the cutting line and a spout portion of the spout

assembly is located right above the cutting line; and sealing a portion of

the main body, where the spout assembly is located.

A portion of the main body, where the spout assembly is not located,

is remained as an unsealed portion.

According to still another aspect of the present invention, there is provided a method for making a pouch container with a spout assembly,

comprising a steps of foirnϊng a main body by releasing films from a roll

of film; forming a cutting on a corner of the main body to defmed a cover

for covering the spout assembly; locating the spout assembly on the

corner of the main body based on the cutting line so that an attaching

portion of the spout assembly can be located right under the cuttmg line;

and sealing a portion the main body, where the attaching portion is

located, together with both sides of the portion.

A preferred embodiment of the present invention will be

described more in detail hereinafter in conjunction with the

accompanying drawings.

An inventive container 1 includes a main body 10 formed of a tube

or a fiim and a spout assem ly 20 attached on an end of the main body 10

to dispense contents contained in the main body 10, wherein a spouting

portion 21 of the spout assembly 20 is covered with a cover 12 that

extends from the main body 10 with a cutting line between them.

When the main body 10 is formed of films, the main body 10 is

formed in a bag-shape using front and rear films 13 and 14 attached to each other. The bag-shaped main body 10 has a lower end defined by

an unsealed portion 15.

In use, the unsealed portion 15 is first opened to fill contents therein.

Then, the front and rear films 13 and 14 are pulled so that side ends 16

becomes sides 17, after which seal is realized. As a result, the seal

portion of the cover 12 and a seal portion 18 formed along a centerline CL

are perpendicularly disposed.

In order to use the contents, the cover 12 is cut away by cutting the

cutting line 11 and the closer formed on a top of the spout portion 21 is

removed.

FIGS. 2 through 6 show a pouch container with a spout assembly

according to another embodiment of the present invention.

The embodiment will be described hereinafter. Although identical

reference numerals are used, they do not any relations with the forgoing

embodiment.

A container 1 has a main body 10 formed of front and rear films 11

and 12 attached to each other.

A spout assembly 20 for discharging contents is attached on an

upper portion of the main body 10. The spout assembly 21 may be covered by a cover 14 extending from the main body 10 with a cutting line

13 between them .

In addition, a gusset portion 15 is formed on a lower portion to

define a folded lower portion 16 formed by folding the front film 11. The

gusset portion 15 is folded and extended to define an unsealed portion 17

with the rear film 12.

Alternatively, the gusset portion 15 may be formed by a lower end of

the rear film 12. Alternatively, the gusset portion 15 may be formed by a

separated film .

An operational effect of the present invention will be described

hereinafter.

From a state depicted in FIG. 2, contents are filled in through the

unsealed portion 17, and than the unsealed portion 1 is sealed.

In order to use the contents filled in the container 1 , the cover 13 is

cut away by cutting the cutting line 13 and a closer formed on the spout

portion 21 is moved by being twisted. By doing this, the contents can be

discharged through the spout portion 21 .

FIG. 4 shows a state where side portions of the container 1 is

removed in a predetermined shape to improve the self standing force. FIG. 5 shows a state the unsealed portion 17 is sealed after the

contents are filled through the unsealed portion 17. This shows that the

self-standing force can be improved.

FIG. 6 shows a front view of FIG. 5.

Alternatively, the gusset portion 15 may be formed by a separated

film.

FIGS. 7 and 8 show a method for making a pouch container with a

spout assembly according to an embodiment of the present invention.

The reference numerals used in this embodiment do not relate to those of

the forgoing embodiments.

Referring to FIGS. 7 and 8, the film F is released from a roll and the

cutting line 10 is formed to define a cover 11. Based on the cutting line

10, an attaching portion 100 of the spout assembly 100 is located right

under the cutting line 10 and the spout portion 101 with the closer 102 is

located right above the cutting line 10.

The container 1 has a seal portion formed on both sides of a portion

where the spout assembly 100 is attached. The cover is also sealed by a

seal portion 4 to hygienically protect the spout portion 101 .

The above-state is shown in FIG. 7. The container shown in FIG. 7 is made through a series of processes shown in FIG. 8.

In use, contents are first filled in the container through an

unsealed portion 5 and the unsealed portion 5 is sealed, thereby

providing a product A.

In order to use the contents contained in the container, the cover

11 is removed from the container 1 by cutting the cutting line 10.

In this state, the closer 102 is twisted and removed from the

spout portion 101. The contents can be exhausted through the spout

portion 101.

The filling process and the sealing process can be consecutively

performed.

The spout assembly 100 may be attached on a corner of a pouch

container 1 and^'covered by a cover with a cutting line between the cover

and the pouch container 1.

In this case, the unsealed portion may be formed on a top of the

pouch container 1 and the bottom can be sealed. Furthermore, a

bottom gusset may be formed on a bottom of the pouch container 1.

nvrr TCTΌT Λ T Λ pτ_>τ τr> Λ TOTT T V As described above, the present invention is directed to a pouch

container with a spout assembly, in which the spout assembly can be

hygienicaily protected. The present invention is further directed to a

method for mass production of such a pouch container.
