Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag made of a soft wrapping material which can be filled with liquids or powders such as foods, detergents and chemicals.

[0002]

2. Description of the Related Art A so-called standing pouch is known for this type of soft packaging material bag, in which the bottom is folded into a W shape and the peripheral portion for filling the contents is heat-sealed. The flexible packaging material bag of the present invention is not limited to the above-mentioned standing pouch, but the flexible packaging material bag is one in which the body portion of the bag filled with the contents is strongly pushed by hand and poured out into another molded container at once. Thus, it was extremely difficult to pour out an appropriate amount while the bag was filled with the contents. The present inventor has provided a flow path bending portion in the outflow passage of the contents from the body portion filling the contents of the bag made of the soft packaging material to the spout, thereby bending the flow path and forming the flow path. By making the bag thinner, even if the body of the bag was pressed hard by hand, it was not excessively poured out, and the bag was successfully adjusted and poured out in suitable amounts.

[0003]

DISCLOSURE OF THE INVENTION The present invention provides a bag made of a soft wrapping material in which the amount to be poured out can be easily adjusted and the body can be prevented from being excessively poured out even if it is pushed hard by hand. Things. The present invention also provides a bag made of a soft packaging material which has a good appearance, is simple to manufacture, can be manufactured at low cost, and is easy to dispose of.

[0004]

According to the present invention, there is provided a bag made of a soft packaging material according to the present invention.
In a bag made of a soft wrapping material in which contents can flow out from the spout 14 by manually pushing the body 1, a body having a large flow path cross-sectional area in which the contents can be immediately flowed out by manually pushing the body 11. In order to prevent a large amount of contents from the outlet 12 and the body outlet 12 from flowing out from the spout 14,
It is provided with a flow channel bent portion 15 formed by bending the flow channel and reducing the cross-sectional area of the flow channel, and an outlet 14 through which the contents can flow out. In addition, in order to achieve the above-described object, the bag made of the soft packaging material of the present invention has a width X of the body outlet 12 that is twice or more as large as the width Y of the spout 14, as shown in the drawing.
The width is less than one third of the width Z of the body 11. In the present invention, in addition to the so-called standing pouch, the bag made of a soft packaging material includes all bags that can be poured out by filling the contents and then heat sealing the periphery thereof. The channel bent portion is provided between the body outlet and the spout of the bag, and the configuration of the channel bent and the channel cross-sectional area are determined by the physical properties of the soft packaging material and the contents, the amount of the spout, and the like. Determined.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention is shown in FIGS. The embodiment of the present invention is a standing pouch-type bag made of a soft packaging material. As shown in FIG. 1, a body 11 for filling contents (not shown), a body outlet 12 communicating with the body 11, a body outlet 12 And a spout 14, and a peripheral portion 101 in which the peripheries of the body 11, the body exit 12, the flow bend 15 and the spout 14 are heat-sealed. . The torso outlet 12 is connected to the torso 11
The bottom 13 of the body 11 is formed so as to form an inclined surface toward the body outlet 12 so that the contents can be immediately drained out by pushing the body. Channel bending part 15
Has a meandering flow path and a narrow flow path cross-sectional area C. In the bag made of the soft packaging material according to the present embodiment, the width X of the body outlet 12 in the folded state before filling the contents is:
It is manufactured to be at least twice the width Y of the spout 14 and at most one third of the width Z of the body 11. The width X of the body outlet 12 is set to be at least twice the width Y of the spout 14 in order to make it easier to pour out with a single push, and the width X of the body 11 is made one third or less of the width Z of the body 11. Is to secure a space for the channel bent portion 15 and to secure a space for filling the contents into the bag. As described above, the configuration of the flow path bending portion 15 and the minimum flow path cross-sectional area C are specifically determined by the physical properties of the soft wrapping material and the contents, the amount to be poured out, and the like.
Reference numeral 102 denotes an opening line of the spout 14.

[0006]

Therefore, as shown in the embodiment of the present invention, the contents filled in the torso portion 11 of the flexible packaging material bag of the present invention can be obtained by pushing the torso portion 11 manually. Since the flow passage cross-sectional area of the trunk outlet 12 is large, the flow quickly flows toward the flow passage bent portion 15, but the content that has flowed out to the trunk outlet 12 by passing through the flow passage bent portion 15 in a large amount. Is passed through a tortuous flow path and a section having a small flow path cross-section, so that the flow rate is restricted and the flow is discharged to the spout 14. Therefore, as shown in FIG. 2, it becomes possible to pour out and use an appropriate amount while being hung by the hanger 20 from the hanging holes 103 of the bag.

[0007]

According to the present invention, it is possible to easily control the amount of the content to be poured out, and the formation of the bent portion of the flow path can be controlled by two or more steps.
It can be easily configured by heat sealing the laminated soft packaging material. Further, according to the present invention, there is an advantage that the bag can be manufactured at a low cost without much difference from the conventional product.
