Abstract

A stand-type pouch includes a front portion, a rear portion and a bottom support portion. The front and rear portions are opposite to each other. The bottom support portion is positioned between lower sides of the front and rear portions and folded upward. The bottom support portion has a top surface of which one and the other surfaces facing the front and rear portion are sealed to the front and rear portions, respectively. Accordingly, the folded bottom support portion is unfolded outward by improving the sealing structure of the bottom support portion, so that the pouch is stably raised and has an opening formed wide.

Description

STAND-TYPE POUCH HAVING WIDE OPENING

An aspect of the present invention relates to a stand-type pouch having a wide opening, and more particularly, to a stand-type pouch which can be stably raised and have an opening formed wide.

Pouches are packaging materials that can seal and pack various kinds of powder or liquid food or retort products. The pouches are useful packages for minimizing loss caused by deterioration or decay of contents and the sum of costs caused by small quantity packages, using various plastic films.

However, when pouches are displayed on a sale table, it is difficult to display the pouches because the pouches are not well raised. Further, when a user opens a pouch and eats contents contained in the pouch, the pouch is not well raised. Since an opening of the pouch is formed narrow, the user has difficulty in eating the contents contained in the pouch.

Accordingly, an object of the present invention is to provide a stand-type pouch in which a folded bottom support portion is unfolded outward by improving the sealing structure of the bottom support portion, so that the pouch is stably raised and has an opening formed wide.

According to an aspect of the present invention, there is provided a stand-type pouch, including: front and rear portions opposite to each other; and a bottom support portion positioned between lower sides of the front and rear portions and folded upward, the bottom support portion having a top surface of which one and the other surfaces facing the front and rear portion are sealed to the front and rear portions, respectively.

A second sealing portion at which the bottom support portion is sealed to the front and rear portions may be formed inclined downward from both upper corners thereof.

Edge regions of the front and rear portions except portions of the front and rear portions, sealed to the bottom support portion, may be sealed to each other. A first sealing portion at which the front and rear portions are sealed to each other may be vertically formed downward from both the upper corners and then formed inclined inward.

The pouch may be raised by unfolding the folded bottom support portion to come in close contact with a floor.

The ratio of the height of the second sealing portion to the height of the bottom portion is about in the range of 0.2 to 0.75.

As described above, according to the present invention, it is possible to provide a stand-type pouch in which a folded bottom support portion is unfolded outward by improving the sealing structure of the bottom support portion, so that the pouch is stably raised and has an opening formed wide.

Throughout the drawings, like elements are designated by like reference numerals.

Hereinafter, embodiments of a stand-type pouch having a wide opening according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 is an exploded perspective view of a stand-type pouch according to an embodiment of the present invention. FIG. 2 is a plan view showing a sealing portion of the stand-type pouch according to the embodiment of the present invention. FIG. 3 is a side view of the stand-type pouch in a sealing state according to the embodiment of the present invention.

Referring to FIG. 1, the stand-type pouch according to this embodiment includes a front portion 10, a rear portion 20 and a bottom support portion 30.

The front and

rear portions

10 and 20 are positioned opposite to each other, and form an internal space in which contents (food or the like) are contained, together with the bottom support portion 30.

The bottom support portion 30 forms the internal space in which the contents are contained, together with the front and

rear portions

10 and 20. The bottom support portion 30 comes in contact with a floor or the like later, so that the pouch is raised.

To this end, the bottom support portion 30 is positioned at a lower side between the front and

rear portions

10 and 20 and folded toward an upper side. Here, the upper side refers to an inner side of the pouch, i.e., a direction toward the internal space.

The bottom support portion 30 is preferably folded along a central portion thereof for the purpose of balance. The bottom support portion 30 is folded toward the inner side of the pouch, so that a top surface of the bottom support portion 30 is partitioned into one surface facing the front portion 10 and the other surface facing the rear portion 20.

In the bottom support portion 30, the one surface facing the front portion 10 is sealed to the front portion 10, and the other surface facing the rear portion 20 is sealed to the rear portion 20.

Referring to FIG. 2, the region in which the bottom support portion 30 is sealed to the front and

rear portions

10 and 20 is represented as a second sealing portion S2. As shown in FIG. 2, the one and the other surfaces of the bottom support portion 30 are not entirely sealed to the front and

rear portions

10 and 20 but may be sealed to the front and

rear portions

10 and 20 in only a partial region at an edge of the bottom support portion 30.

The second sealing portion S2 is preferably formed while being inclined downward from both upper corners (see area B of FIG. 2). This is provided to allow the upper side of the internal space (opening) to be widened, instead of forming the lower side of the internal space to be narrow.

That is, this is because the lower side of the internal space is reduced as much as the region sealed while being inclined inward by the second sealing portion S2.

The height h2 of the second sealing portion S2, determined based on a bottom end portion of the pouch, is increased, so that the lower side of the internal space can also be formed narrow.

Particularly, the ratio of the height of the second sealing portion to the height of the bottom portion is about in the range of 0.2 to 0.75.

A bottom surface of the bottom support portion 30, i.e., surfaces opposite to each other by folding the bottom support portion 30 to the upper side are not sealed to each other.

Thus, as shown in FIG. 3, the bottom support portion 30 and the front portion 10 are spaced apart from the bottom support portion 30 and the rear portion 20 each other therebetween at a lower portion of the pouch. Also, as described above, the bottom support portion 30 are sealed to the front portion 10 and the rear portion 20 respectively by the second sealing portion.

The front and

rear portions

10 and 20 are sealed to each other so as to form a sealing state of contents. Referring to FIG. 2, edge regions of the front and

rear portions

10 and 20 except portions of the front and

rear portions

10 and 20, sealed to the bottom support portion 30, are sealed to each other, thereby forming a first sealing portion S1.

An upper sealing portion 40 may be formed by forming the first sealing portion S1 not only at corners of the front and

rear portions

10 and 20 but also at upper portions of the front and

rear portions

10 and 20.

As shown in FIG. 2, the first sealing portion S1 seals both the corners of the front and

rear portions

10 and 20. The first sealing portion S1 may be vertically formed downward from both upper corners thereof.

The first sealing portion S1 may be vertically formed downward from both upper corners thereof and then formed inclined inward (see area A of FIG. 2). That is, unlike the existing pouches, the first sealing portion S1 is set inclined inward from a position higher by a predetermined height than the boundary between the first and second sealing portions S1 and S2.

In other words, the first sealing portion S1 is formed inclined inward from a position higher than the height h1 of the bottom support portion 30.

Thus, while the internal space of the pouch is reduced as much as the region sealed while being inclined inward by the first sealing portion S1, an opening 60 (see FIG. 5) formed at an upper side of the pouch is widened.

In FIG. 2, the angle of the inclined sealing of the first sealing portion S1 is set identical to that of the inclined sealing of the second sealing portion S2 so that each of the sealing portions S1 and S2 corresponds to the boundary of the internal space. However, the angle of the inclined sealing of the first sealing portion S1 may be different from that of the inclined sealing of the second sealing portion S2, and each of the sealing portions S1 and S2 may not correspond to the boundary of the internal space.

FIG. 4 is a side view showing a state that the stand-type pouch in the sealing state is raised according to the embodiment of the present invention. FIG. 5 is a side view showing a state that the stand-type pouch in an opening state is raised according to the embodiment of the present invention.

FIG. 4 illustrates a state that the pouch is raised by unfolding the bottom support portion 30 in the sealing state that the upper sealing portion 40 is not removed.

The bottom support portion 30 folded upward is unfolded outward, and thus the bottom surface of the bottom support portion 30 comes in contact with a floor 50 so that the bottom support portion 30 is stably supported by the floor 50. Accordingly, the pouch does not fall down for a long period of time, so that it is easy to display the pouch on a sale table.

In a case where the opening 60 is formed by removing the upper sealing portion 40 as shown in FIG. 5, a user can eat contents contained in the pouch in the state that the user stably raises the pouch on the floor 50 or palm of the user’s hand, like a bowl.

Another characteristic of the present invention is that the opening 60 can be formed wide. This can be implemented by increasing the height h2 of the second sealing portion S2 that exists at a lower end of the pouch. That is, this is based on a principle that a lower portion in the internal space of the pouch is formed narrow but an upper portion in the internal space of the pouch is formed wide by performing a large amount of sealing at a lower side of the pouch.

Since the lower portion in the internal space of the pouch is formed narrow by the diagonal sealing of the first and second sealing portions S1 and S2, the opening 60 can be formed wide.

The folded bottom support portion 30 is unfolded outward, and thus the front and

rear portions

10 and 20 connected to the bottom support portion 30 are lifted upward by the unfolded bottom support portion 30. Accordingly, the opening 60 can be formed wide.

FIG. 6 is a view showing a method of utilizing the stand-type pouch according to the embodiment of the present invention. The method of utilizing the stand-type pouch according to the present invention will be described with reference to FIG. 6.

First, a purchaser removes the upper sealing portion 40 of the pouch in which food is sealed, using scissors or the like ((a) of FIG. 6). Accordingly, the opening 60 is formed at an upper side of the pouch, and the opening 60 is formed wider by the uniqueness of the sealing shape of each of the sealing portions S1 and S2.

Then, the purchaser unfolds the folded bottom support portion 30 to both sides ((b) of FIG. 6). Accordingly, the opening 60 is extended wider, and the bottom support portion 30 comes in contact with a floor or the like by the weight of contents, so that the pouch can be stably raised on the floor 50 or the like.

The pouch having the unfolded bottom support portion 30 is put on the floor 50, so that the purchaser can conveniently eat the contents in the state that the pouch is raised ((c) of FIG. 6). In addition, the purchaser can conveniently eat the contents in the state that the pouch is put on the palm of a purchaser’s hand ((d) of FIG. 6).

While the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims, and equivalents thereof.
