BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin film container, and more particularly, to a method for filling and packing refill contents such as detergents, cosmetics, sugar and salt, and refilling the contents into a main container. The present invention relates to a resin film container in which a spout can be easily formed.

[0002]

2. Description of the Related Art Conventionally, a resin film bag packed and packaged with refill contents such as detergents, cosmetics, sugar and salt has an innermost layer made of a heat-sealable material, In general, a V-shaped cut for forming an opening was provided in a side seal portion near the portion.

In such a conventional bag made of a resin film, as a method of taking out the filled contents, the bag is torn from the above-mentioned V-shaped cut and its corner is cut into a substantially triangular shape. The contents were poured out from the opening that appeared at the corner.

[0004]

However, in this type of conventional bag, it is easy to actually tear the bag from the V-shaped cut by hand and cut the corner into a substantially triangular shape and open it. is not. In addition, even when opened in this way, the opening is too large or too small to be stable, and since this opening is a direct opening in the internal space of the bag, it is difficult to take out the contents. There is a problem that a large amount of contents may concentrate on the opening and vigorously come out, and if the inclination of the bag at the time of removal is not taken into account, there is a risk of spilling from the main container to be transferred and contaminating the surroundings.

SUMMARY OF THE INVENTION An object of the present invention is to solve such a conventional problem, and it is possible to form a passage-shaped spout when taking out contents, and to form the spout. It is an object of the present invention to provide a resin film container which can be almost exactly broken along a predetermined tearing line and can easily form a mouth having the most preferable size for taking out the contents.

[0006]

Means for Solving the Problems The present invention relates to a container made of a resin film, and is constituted as follows in order to solve the above-mentioned technical problems. In other words, the present invention comprises at least a sealant layer on the innermost layer and a film layer in a specific direction other than the innermost layer, which is easy to cut, and at least one corner is cut into a generally hook shape to facilitate the spout. A resin film container which can be formed at a predetermined angle along one side of the corner portion and at a distance from the one side, and extending in a direction intersecting a specific direction in which the film layer can be easily cut in a specific direction. A seal portion having a length, and a spout formed on the seal portion, each end of which is directed in the longitudinal direction of the seal portion and in the one side direction along a specific direction in which the film layer can be easily cut in a specific direction. It is characterized by comprising a cut portion, and a cut for cut provided in the extension direction of one end of the cut portion for forming a spout, which is directed outward in the longitudinal direction of the seal portion. .

<Additional Configuration in the Present Invention> The resin film container of the present invention comprises the above-mentioned essential components, but is established even when the following components are further added to the components. . The additional component is characterized in that the sealing portion is provided with at least one auxiliary notch at a position longitudinally inward of the cutout for forming a spout.

In the resin film container of the present invention,
It is also preferable that the auxiliary cut portion is connected to the spout forming cut portion. Further, it is preferable to provide a tearing stress distribution opening in the seal portion at a position further inward in the longitudinal direction than the auxiliary cut portion. In this case, you may make it connect an auxiliary | assistant cut part and a tearing stress distribution opening.

According to the resin film container of the present invention, when the user opens the resin film container and takes out the contents, the user inserts his / her finger through the cutout for forming the spout to form the resin film container. Tear the corners of the container. The tearing force at that time acts from both ends of the cutout for forming the spout in the extending direction.

One end of the cutout portion for forming a spout is directed outward in the longitudinal direction of a seal portion formed along one side of the resin film container, and this direction can be cut in a specific direction. Although it is difficult to cut because it is a direction that intersects with the specific direction, a cutting cut, for example, a perforation is provided on the extension of one end, so that the seal portion is vertically edged along the cutting cut. Part torn.

Since this direction is difficult to cut, it is usual to provide a cut for cutting very close to the edge. However, when forming a spout, the corner cut piece of the container is completely separated from the container itself. It is also possible to provide a cut so as not to reach the vicinity of the edge so as not to prevent the cut. In this manner, the corner cut pieces do not become dust and are not scattered after the spout is formed.

On the other hand, the other end of the cutout portion for forming a spout is easily cut because it is directed to one side of the resin film container along a specific direction in which the film layer is easily cut in a specific direction. Therefore, the tearing force acting on the other end easily tears the resin film container toward one side. As a result, the corners of the resin film container are cut into a generally hook shape, and a portion sandwiched between the seal portion and one side is opened, and at the same time, this portion becomes a passage for taking out the contents.

When the corner of the resin film container is cut into a substantially key shape from the cutout for forming the spout in this manner, a part of the tearing force acting on the cutout for forming the spout is caused by the longitudinal direction of the seal. In the case where the cutout portion for forming a spout and the auxiliary cutout portion below the cutout portion are discontinuous, the seal portion between them is torn to disconnect the cutout portion for forming a spout and the auxiliary cutout portion. .

When the seal between the cutout for forming the spout and the auxiliary cutout is torn apart to make it continuous, the tearing force is instantaneously absorbed by the tearing stress dispersion opening provided at the lower end of the auxiliary cutout. As a result, the content does not reach the content accommodating space of the resin film container beyond the inner end of the seal portion. In this manner, the longitudinal cut is made in the seal portion itself, so that the passage portion of the portion sandwiched between the seal portion and one side becomes independent as a spout from the content storage space.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a resin film container according to the present invention. FIG. 1 shows a resin film container 10 according to one embodiment of the present invention. This resin film container 10
Is a container made of a resin film capable of easily forming a spout by cutting at least one corner into a generally hook shape.

The resin film container 10 includes at least two or more resin film layers each having a sealant layer at least as the innermost layer and a film layer which is easy to cut in a specific direction arranged at another layer except the innermost layer. It is configured. The reason why the sealant layer is provided as the innermost layer is to make it possible to close a necessary portion by heat sealing or the like. As the sealant layer, a heat-sealable material such as low-density polyethylene is preferably used, but a layer that can be bonded and sealed with an adhesive or the like may be used.

That is, this resin film container 10
As is clear from FIG. 1, when the contents are not contained, the flat shape is almost rectangular in the vertical direction, and the edges 11a and 11b on both sides and the edge 11c on the bottom are sealed by heat sealing or the like. It is configured to include a stopped bag-shaped container body 11.

The "specific direction easy-to-cut film layer" is, for example, a resin film layer stretched in one direction or a resin film layer stretched in two directions at different stretching ratios. An example of such a film that can be easily cut in a specific direction is “Kariariyan Y” (trade name) of Toyo Chemical Co., Ltd.

This resin film is a film in which a high-density polyethylene resin is uniaxially strongly stretched and highly oriented, and has been developed for the purpose of "having sufficient strength and being easily torn". Besides this resin film,

0, the specific-direction easy-to-cut film layer is provided in the container 1 as shown by the arrow A in FIG.
0 are arranged in the horizontal direction. Such a resin film container 10, in addition to the specific low-density polyethylene layer of the innermost layer and the specific-direction easy-to-cut film layer disposed at an arbitrary position other than the innermost layer, For example, in order to provide gas barrier properties and water resistance, a nylon or poval resin film can be disposed in the intermediate layer or the outermost layer. The presence of the specific-direction cuttable film in the layer allows the laminate itself to have the specific-direction cutability even if the other layer is not set to be easily cut in the specific direction.

The bag-shaped container main body 11 has a vertical portion that crosses a specific direction in which the film layer can be easily cut along the edge 11a on one side from the upper edge in the vicinity of one corner. A seal portion 12 is formed in a predetermined length at a position extending in the direction and spaced from the edge portion 11a.
The seal portion 12 is preferably formed by heat sealing, but may be sealed using an adhesive or the like.

The seal portion 12 has a cutout portion 13 for forming a spout, which is substantially L-shaped. One end 13a of the cutout 13 for forming a spout, which is substantially L-shaped,
The edge 11a is oriented in the longitudinal direction outside of the seal portion 12, that is, in the direction of the upper edge portion of the container body 11, and the other end 13b is one side described above along the specific direction in which the film layer can be cut easily in the specific direction. Orientation in the direction.

Further, the cut portion 14 is formed in the seal portion 12 in the extending direction of the one end 13a of the cutout portion 13 for forming a spout.
Are formed. One end 1 of cutout portion 13 for forming a spout
The extension direction of 3a is a direction that intersects with the specific direction A in which the easy-to-cut film layer can be cut in the specific direction. Therefore, a cutting notch 14 made of perforations or cuts is provided for the purpose of assisting tearing in this direction. When the spout is formed, it may be provided as shown in FIG. 5 or FIG. 6 so that the cutout does not reach the vicinity of the edge so that the corner cut piece of the container 10 does not completely separate from the container itself. . In this manner, the corner cut pieces do not become dust and are not scattered after the spout is formed.

The seal portion 12 may be provided with one auxiliary cut portion 15 on the inside of the seal portion in the longitudinal direction, that is, at a position closer to the center of the container body 11 than the cutout portion 13 for forming a spout. You may. Further, a tear stress dispersing opening 16 may be provided on the lower side. The former auxiliary notch 15 has a linear shape extending straight in the longitudinal direction of the seal portion 12, and the latter tearing stress distribution opening 16 is a round hole formed at a position close to the lower end of the auxiliary notch 15. To prevent further breaks.

The resin film container 10 constructed as described above is filled with the contents from the unsealed upper edge portion, and then the upper edge portion is sealed with a seal.
The seal at the upper edge is indicated by reference numeral 11d in FIG. However, the opening for filling the contents into the resin film container 10 is not limited to this upper edge, and it goes without saying that any edge may be used.

Next, the procedure for opening the resin film container 10 in which the contents are accommodated and the upper edge portion is sealed will be described. When the user opens the resin film container 10 and removes the contents, the user inserts a finger into the cutout 13 for forming a spout to tear a corner of the resin film container 10.

The tearing force at that time acts from both ends 13a and 13b of the cutout portion 13 for forming the spout in the extending direction thereof. One end 13a of the cutout portion 13 for forming a spout
Is an edge 11 which is a side of the resin film container 10.
a, it is difficult to cut because the direction intersects with the specific direction A in which the film layer can be cut easily. Since the perforations 14 and the like are provided on the extension of 13a, the seal portion 12 is torn vertically to the upper edge 11d along the perforations 14 and the like.

On the other hand, the other end 1 of the cutout portion 13 for forming a spout
3b is easy to cut because it is directed to the edge 11a which is a side of the resin film container 10 along the specific direction A in which the film layer can be easily cut in the specific direction. Therefore, the tearing force acting on the other end 13b easily tears toward the resin film container 10 edge 11a.

As a result, the corner portion of the resin film container 10 is cut off in a substantially hook shape as shown in FIG. 2, and a portion (region) sandwiched between the seal portion 12 and the edge portion 11a.
17 is opened, and at the same time, this portion becomes a spout or a spout passage for taking out the contents.

Thus, the cutout portion 13 for forming the spout is formed.
When the corner portion of the resin film container 10 is cut into a substantially hook shape from the opening, a part of the tearing force acting on the cutout forming cutout 13 is also transmitted in the vertical direction of the seal portion 12, and the cutout forming cutout is formed. The sealing portion between the cutout 13 and the auxiliary cutout 15 located below the cutout 13 is torn so that the cutout 13 for forming the spout and the auxiliary cutout 15 are continuous.

When the seal portion 12 between the cutout portion 13 for forming the spout and the auxiliary cutout portion 15 is torn to make it continuous, the tearing force is instantaneously increased by the tearing stress dispersion opening 16 provided at the lower end of the auxiliary cutout portion 15. Is absorbed by As a result, it does not extend to the content accommodating space of the resin film container 10 beyond the inner end of the seal portion 12.

In this manner, the transverse cut is made in the seal portion 12 itself, whereby the above-described seal portion 1 is formed.
A spout passage 17 formed at a portion sandwiched between the edge portion 2 and the edge 11a is formed as if it were independent from the content accommodating space, and the front end of the passage has an opening 1 of the spout.
7a.

As described above, when the spout is formed and the contents are poured out from the spout, if the air is introduced into the container body from another portion, the contents can be smoothly flowed out.
Therefore, as shown in FIG.
A similar seal portion 18 is formed in the upper portion on the opposite side from the position where the is formed, and in the vicinity of the other side. An air inlet can be formed by forming a cutting cut 20 and cutting the corner completely or leaving it in an incompletely cut state.

The container 1 made of the resin film of the embodiment described above.
In the case of No. 0, the cutout 13 for forming a spout, the auxiliary cutout 15 and the tearing stress dispersion opening 16 provided in the seal portion 12 are all discontinuous, but as shown in FIG. Alternatively, the cutout portion 13 for forming a spout and the auxiliary cutout portion 15 may be connected in advance.

Similarly, as shown in FIG. 4, which partially shows the seal portion 12, the auxiliary notch portion 15 and the tearing stress distribution opening 16 may be connected in advance, or as shown in FIG. Cut-out part 1 for spout forming auxiliary cut-out part 15
3, and the auxiliary cut portion 15 may be connected to the tearing stress dispersion opening 16 in advance.

Furthermore, in the resin film container 10 of the above-described embodiment, the cutout portion 13 for forming the spout formed in the seal portion 12 is substantially L-shaped, but the present invention is not limited to this. However, as described above, one end is directed in the longitudinally outward direction of the seal portion 12, that is, in the direction of the upper edge of the container body 11, and the other end is formed along the specific direction in which the film layer can be easily cut. A trapezoidal shape as shown in FIG. 6 may be used as long as it is directed in the direction of the edge 11a which is one side.

Although not shown, the auxiliary cut portion formed below the cutout forming cut portion 13 can also be formed in various shapes, and as an example, the upper portion is thin like a water drop shape. , The lower portion may be gradually thicker.

As described above, according to the resin film container of the present invention, a passage-shaped spout can be formed when the contents are taken out, and when the spout is formed, a predetermined spout can be formed. Almost exactly along the tear line,
The mouth having the most preferable size for taking out the contents can be easily formed.
