Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same components are denoted by the same reference symbols whenever possible. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

3 is a perspective view showing the pouch shown in FIG. 2, wherein the pouch 100 includes a lower film having a predetermined size (for example, An upper film 120 disposed on the lower film 110 and having a size corresponding to the lower film 110 and an upper film 120 having a size corresponding to the lower film 110 and the upper film 120, (Not shown).

The lower film 110 and the upper film 120 are made of a packing film for sealing having a certain size as an embodiment of the present invention. The lower film 110 and the upper film 120 have a size and a shape corresponding to each other. It should be noted that the lower film 110 and the upper film 120 may be used in various sizes and shapes.

The lower film 110 and the upper film 120 may be made of an inner material, that is, a polyethylene (PE) film or a polypropylene (PP) film on the adhesive surface. Or an easy peel film between the lower film and the entire upper film and the entire portion of the seam line.

 The sealing line 130 includes an edge sealing line 131 for sealing the edge of the upper film and forming a first packaging space 141 at a central portion of the upper film 110 and a portion of the edge sealing line 131 A first collapse line 132 formed at a predetermined distance from the first collapse line 132 and a second packing space 142 formed at a position spaced apart from the first collapse line 132 by a predetermined distance between the first collapse line 132 and the first collapse line 132, ) Of the second collapse line (133).

The first and second decay lines 132 and 133 are formed between the lower film 110 and the upper film 120 so that the upper and lower films 110 and 120 are sealed When the first packaging space 141 is sealed with the easy peel film and the predetermined pressure is applied to the first packaging space 141, the edge sealing line 131 is not collapsed and the first and second collapse lines 132 and 133 are separated from the inside So that the pouch 100 can be easily opened, and the pouch 100 can be easily transported and managed.

The pouch 100 according to an embodiment of the present invention is designed such that the first and second collapse lines 131 and 132 which are the compression sealed faces of the opening 134 at the time of use must be pushed out and pushed to the side or bottom of the pouch 100 And the edge sealing line 131 is structured so as not to be blown.

For this purpose, the peeling strength should be different by different sealing sealing conditions of the edge sealing line 131 and the first and second decay lines 131 and 132.

That is, the edge sealing line 131 is subjected to sealing sealing by full thermocompression bonding, and the first and second decoupling lines 131 and 132 are sealed by semi-heat pressing. Here, sealing sealing of full thermocompression refers to a method of making the peeling strength of 1.5 kgf / 15 mm or more, and the term "compression sealing of semi-heat pressing" means that the peeling strength is 0.5 kgf / 15 mm or more and 1.2 kgf / 15 mm or less How to do it. It is a matter of course that the above sealing temperature and peel strength can be varied.

Particularly, the first and second decay lines 131 and 132 are subjected to a compression sealing process of a semi-heat pressing process including an easy peel film between the lower film 110 and the upper film 120.

When the semi-heat compression bonding is performed with the lower film 110 and the upper film 120, that is, the inner material is made of polyethylene (PE) or polypropylene (PP) 1 and 2 collapse lines 131 and 132 are not collapsed. Also, if the lower film 110 and the upper film 120 are used as a single material of polyethylene (PE) or polypropylene (PP) film, the deviation of the sealing strength due to the thermocompression becomes severe even with a slight temperature deviation. When the strength is too weak, the first and second collapse lines 131 and 132 collapse too easily, and the contents unintentionally flow out during the circulation of the pouch 100. On the contrary, when the sealing strength is too high, The first and second collapse lines 131 and 132 are not collapsed when the cover 100 is opened.

Therefore, when the first and second decay lines 131 and 132 are subjected to the compression sealing of the semi-heat pressing including the easy peel film between the lower film 110 and the upper film 120, It is possible to maintain a peel strength of 0.5 to 1.2 kgf / 15 mm, which is a possible sealing strength, so that the sealing strength, which is a problem when using only the lower film 110 and the upper film 120, is so weak that the first and second collapse lines 131 and 132 are prevented from collapsing and the consumer can easily use the pouch 100 when the pouch 100 is used due to proper sealing strength.

Table 1 below shows the peel strength measurement values of polyethylene (PE), polypropylene (PP), and easy peel film subjected to compression bonding by thermocompression bonding by temperature, respectively. .

The peel strength was measured by peeling the films with each other at a pressure of 3 kgf / cm 2 and then peeling the heat-sealed films in the longitudinal direction in a tensile strength tester by cutting the films to a size of 15 mm 50 mm (sealing width) Strength).

At this time, the tensile (peeling) speed was 300 mm / min. Typically, the peel strength that an adult can separate by hand is 2.0 kg / 15 mm or less, and in the case of an ejifilm film, a level of 0.5 to 1.2 kg / 15 mm is suitable. The peel strength measurement temperatures were measured at 145-200 (5 intervals), respectively

As shown in Table 1, the peel strength after thermocompression bonding of a single material of polyethylene (PE) or polypropylene (PP) shows that the difference in the peel strength, which is the heat sealing strength, varies greatly as the temperature increases by 5 degrees It can be seen that the peel strength after heat peeling and peeling of the easy peel film maintains the peel strength value of 0.5 to 1.2 kg / 15 mm even when the temperature is changed by 30 degrees .

That is, the first and second decay lines 131 and 132 include an easy peel film between the lower film 110 and the upper film 120, It can be understood that the peel strength as the heat sealing strength is 0.5 to 1.2 kgf / 15 mm, and thus the sealing strength can be maintained properly and reliably. As a result, the consumer can always use the same pressure and force to collapse the first and second decay lines 132, 133 without any change in the environment, so that the pouch 100 can be opened and used so that the productivity of the pouch 100 can be improved And quality can be maintained.

Herein, as an easy peel film production method, there is a method of producing two layers or three layers by an inflation method and a co-extrusion method. In one embodiment of the present invention, an easy peel film includes a first, 2 function to form a sealant layer at the joint surfaces of the collapse lines 131 and 132. It is a product produced by applying an inflation-type 3layer layer, but it can be produced by any other method depending on conditions. Of course.

In the embodiment of the present invention, the first and second collapse lines 131 are formed at the edges of the pouch 100, respectively. Here, one or more second collapse lines 132 may be formed, and a plurality of packing spaces 140 may be formed.

3 to 5, when a user applies pressure to the first packaging space 140 when using the pouch 100 by forming a plurality of collapse lines, the first packaging space 141 of the plurality of collapse lines, The second collapse line 133 collapses and the first packaging space 141 and the second packaging space 142 are communicated with each other and the contents are moved to the second packaging space 142. [ Next, when pressure is applied to the first packaging space 141, the first collapse line 132 collapses to open the opening 134, and the contents come out.

Since a plurality of collapse lines are formed in this manner, the contents of the packaging space 140 can be prevented from being suddenly poured. Further, since the pouch 100 is required to pass through a plurality of collapse lines 131 in order to open the pouch 100 The leakage of the contents of the pouch 100 can be prevented even if one of the plurality of collapse lines collapses.

In order to open the pouch 100 as described above, it is necessary to apply pressure to the packaging space 140 of the pouch 100. In order to easily generate pressure, the first and second packaging spaces 141 and 142 Or the size of the first or second packaging space 141 or 142 is reduced by increasing the area of the edge sealing line 131 which is sealed by thermocompression bonding to increase the internal pressure, So that it can be facilitated. Alternatively, by folding the packaging space at the time of use, it is possible to increase the internal pressure and make the opening more easily.

The packaging space 140 may include a first packaging space 141 for storing contents in the inner space and a second packaging space 142 formed between the first and second collapse lines 132 and 133.

The first packaging space 141 may contain a liquid product to be used in the pouch 100. For example, various products such as various liquid cosmetics, cosmetic products such as shampoo, and liquid medicines may be contained. In an embodiment of the present invention, the overall shape is rectangular and the upper part is a funnel shape. However, it is needless to say that the shapes and shapes may be variously changed.

The second packaging space 142 serves as a buffer space serving as an internal space formed between the first and second collapse lines 132 and 133 when the collapse line is sequentially blown from the inside of the pouch 100. That is, when the user pressurizes the first collapsing line 133 and presses the second collapsing line 133, the contents of the first packing space 141 pass through the second collapsing line 133, The content of the pouch 100 is stably discharged as compared with the case where there is one collapse line because the contents are discharged through the opening 134 when the user breaks the first collapse line 132 by applying pressure again . In addition, as described above, a plurality of collapse lines also serve to prevent the contents from leaking during the transportation and distribution of the pouch 100.

7 is a plan view showing a pouch which is easy to open according to various embodiments of the present invention. In the first packaging space 141, the lower film 110 and the upper film 120 are completely thermally compressed So that the speed at which the contents are ejected can be slowed down.

7 (a), a first collapse line 132 is formed in the pouch 100 and a plurality of first collapse lines 132 are formed in the first package space 141, And the inner sealing line 135 is formed in the transverse direction. According to the inner suture line 135 formed as described above, when the user applies pressure to the first package space 141, the contents do not flow immediately and are obstructed by the inner suture line 135, Is delayed.

7 (b), a first collapse line 132 and a second collapse line 133 are formed in the pouch 100, and the first collapsing line 132 and the second collapse line 133 are formed in the first packaging space 141 A plurality of inner sealing lines 135 having a predetermined length are formed in the lateral direction. Likewise, when the user applies pressure to the first packaging space 141, the contents do not flow immediately but are disturbed by the inner seam line 135, which complicates the movement path, so that the ejection speed is slowed down.

7 (c), a first collapse line 132 and a second collapse line 133 are formed in the pouch 100, and the first packaging space 141 is formed in the pouch 100, And divided into two by an internal decay line 136 formed vertically. According to the inner decay line 136 formed as described above, the different contents can be filled in each of the divided first packing spaces 141, and then the inner decay line 136 can be used after bursting and mixing.

8 is a plan view showing an application example of a pouch that is easy to open according to another embodiment of the present invention, in which one or more pouches 141a can be coupled to the opening 134 of the pouch 100 . This is because the first packaging space 141 of one pouch 100 and the other pouch 100a are coupled to each other and filled with other contents in the packaging space to form a product. The first and second decay lines 132 and 133 of the pouch 100 are opened to inject the contents in the first packaging space 141 into the packaging space 141a of another pouch 100a, And then use it.

FIG. 9 is a flowchart illustrating a method of manufacturing a pouch that can be easily opened according to an embodiment of the present invention. The method includes the steps of: (S220) of filling the contents in the first packaging space (141) with the upper end of the pouch (100), and a pre-compression sealing step (S210) A partial compression squeeze-sealing step (S230) in which the remaining part of the pouch except the opening part 134 is completely sealed, and a partial squeeze-sealing step (S230) in which the first decoupling line 132 or the second decoupling line 133 is semi-heat- (S240).

First, in the embodiment of the present invention, the compression sealing is performed several times in manufacturing the pouch 100 as described above. When pressure is applied to use the pouch 100, only the first and second collapse lines 132 and 133 The collapsed and seamed seams 131 are pressure sealed at different temperatures and pressures in order to withstand pressure and remain unfired.

The preliminary squeeze-sealing step S210 is a step of sealing the upper and lower films 110 and 120 to fill the contents in the pouch 100 by compression-sealing the edges of the upper and lower films 110 and 120, Sealing step so that the peel strength of the edge seam is 0.5 kgf / 15 mm or more and 0.6 kgf / 15 mm or less.

The contents filling step S220 is a step of filling a predetermined amount of contents into the packaging space 140 formed in the preliminary squeeze-sealing step S210, i.e., the first packaging space 141. [

The unsealed partial pressure sealing step S230 is a step of sealing the edge seaming line 131 of the preliminarily press-sealed pouch 100 with the edge sealing line 131 by completely sealing the remaining portion except the portion where the opening portion 134 is formed, Is a step of performing compression sealing so that the peel strength of the edge sealing line is 1.5 kgf / 15 mm or more and 2.0 kgf / 15 mm or less.

As described above, the gas is injected into the first or second packaging space 141 or 142 so that the pressure can easily be generated in the packaging space 140 of the pouch 100, The size of the packaging space 140 may be reduced by increasing the area sealed with the thermocompression bonding material 131 to increase the internal pressure, thereby facilitating the opening of the packaging space 140.

Here, the gas to be injected into the packaging space 140 may be an inert gas such as nitrogen gas, and various gases may be used as needed.

In addition, in the embodiment of the present invention, when the area of the edge sealing line 131 is increased, the upper end of the first packaging space 141 is shaped like a funnel. However, Of course.

In the popping partial pressure sealing step S240, only the first and second decoupling lines 132 and 133, which are left unpressed and sealed in the non-popping partial pressure sealing step S230, are sealed by semi-heat sealing to seal the pouch 100 Thereafter, in order to allow the user to open the pouch 100 by pressure under pressure, the first and second decay lines are compression-sealed so that the peel strength of the first decay line or the second decay line is 0.5 kgf / 15 mm or more and 1.2 kgf / 15 mm.
