Description

  The present invention relates to a packaging container. More specifically, the present invention relates to a standing pouch that is mainly for filling food that is cooked and / or eaten in a state where the container is filled, and that is highly self-supporting and does not fall easily.

  A wide variety of food packaging containers are currently selected and used depending on the characteristics of their contents, etc.Especially for standing pouches, space saving of product shelves at the time of sale, It has characteristics such as tableware substitutability and is widely used in the food industry.

  This standing pouch is configured by attaching two side members and a folded bottom member disposed therebetween at each attachment portion. Then, after filling and sealing the contents from the top, the folded bottom member is stretched so that the adhering portion between the side member and the bottom member spreads in a substantially circular shape, and this portion ensures self-supporting properties.

  However, the normal standing pouch that has been distributed in the past has a uniform flat surface when it is spread out in a substantially circular shape because the adhering part (the bottom part when the bag is closed) of the side member and the bottom member is straight. Often not. That is, there is a problem that the contact portion between the adhering portion and the floor surface that is spread out in a substantially circular shape is not horizontal, so that the self-supporting property is not sufficient, and it falls down when cooking or eating in a microwave oven or the like.

  As a means for solving this problem, a packaging container (Patent Document 1) that does not adhere to the outer surfaces of the bottom adhering band portions and can extend the adhering band portion of the bottom portion substantially horizontally has been proposed. There is a continuing need in the industry to develop a standing pouch with a simpler structure and higher independence.

JP 2000-21655 A

  An object of the present invention is to provide a packaging container (standing pouch) for filling food that is cooked and / or eaten mainly in a state of being filled in a container with a simple structure and high self-supporting property. To do.

  In order to achieve the above object, the present inventors have conducted intensive research. As a result, in the stunting pouch in which two side members and a folded bottom member disposed between the two side members are attached at the attachment portion, Both ends of the attached portion of the member and the bottom member are cut obliquely upward from the bottom of the bag, and the length of the uncut portion of the attached portion is 30 to 35% of the length of the bag, and The inventors have found that the above-mentioned problems can be solved by making a packaging container having a configuration in which the length of the side surface adhering portion is 3 to 5% shorter than the length of the bag by cutting.

That is, the embodiment of the present invention is as follows.
(1) In a stunting pouch in which two side members and a folded bottom member disposed between them are attached at an attachment portion, both ends (A) of the attachment portions of the side member and the bottom member are from the bottom of the bag. The length of the uncut portion (B) of the adhering portion is 30 to 35% of the bag width, and the length of the side adhering portion (C) Is a container 3 to 5% shorter than the length of the bag by cutting.
(2) The packaging container according to (1), wherein the cut surface (D) is not horizontal but is cut in multiple stages.
(3) It is for filling foods (for example, pregelatinized rice and processed products thereof) that are cooked and / or eaten in a state filled in the packaging container, (1) Or the packaging container as described in (2).

  According to the present invention, when the bottom member folded in two is filled after the contents are filled and the attachment portions of the side member and the bottom member expand in a substantially circular shape, a plurality of contact portions between the spread attachment portions and the floor surface can be formed. Therefore, stability can be maintained, whereby a packaging container (standing pouch) having high self-supporting property in a state where the contents are filled can be provided. This makes it easy to pour hot water directly into the contents of the food and to eat the contents of the food directly, that is, the container can be used as a substitute for cooking utensils and dishes. . The container has almost no difference in overall shape as compared with a conventional standing pouch, and can be used without any difference from a conventional standing pouch in terms of machine suitability and distribution during industrial production. Is also a feature.

The upper row shows the external view of the standing pouch, and the lower row shows the internal view. In both cases, the upper part is the opening part and the lower part is the bag bottom. In addition, the center thick line in the inner view represents a water injection line. In the figure, reference numeral A denotes both ends of the attached portion of the standing pouch side member and the bottom member (parts cut obliquely), reference character B denotes an uncut portion of the attached part of the standing pouch side member and bottom member, and reference C Is a standing pouch side member adhering portion after cutting, and symbol D is a cut surface at both ends of the adhering portion of the standing pouch side member and the bottom member. The numbers in the figure indicate the length of the range indicated by the arrows (unit: mm).

  The present invention is a packaging container (standing pouch) having a simple structure and high self-supporting property, and a typical example of its structure and configuration is shown in FIG.

  The container is a stunting pouch in which two side members, and two side members and a bottom member folded between them are attached to each other at an attachment portion. And both ends (A) of the adhering portion of the side surface member and the bottom surface member are cut obliquely upward from the bottom of the bag (the bottom when the bag is closed), and the uncut portion of the adhering portion The length of (B) is 30 to 35% (preferably 30 to 33%) of the bag width, and the length of the side surface adhering portion (C) is 3 to 3 than the length of the bag by cutting. 5% (preferably 4 to 5%) is short. Thereby, when the contents are filled and the adhering portion of the side member and the bottom member spreads in a substantially circular shape, a plurality of contact portions between the container and the floor surface can be formed, so that stability is maintained.

  In the present invention, the relationship between the length of the uncut portion (B) of the attached portion of the side member and the bottom member that is the bottom of the bag and the length of the bag width, and the length and the side of the attached side portion (C) The relationship of the length of the entire side (bag vertical width) is very important. By maintaining the relationship between these lengths within a certain range, when the adhering portion of the side member and the bottom member spreads in a substantially circular shape, a plurality of contact portions between the container and the floor surface can be created, thereby maintaining stability. Play for the first time. As for the cutting of both ends of the adhering portion, cutting may be performed on the plane once (one step), but it is not essential to cut in one step, and cutting is performed by changing the angle in several steps. It may be performed (for example, two-stage cutting for giving one vertex to the cut surface at both ends of the attachment portion). In addition, by setting it as multi-stage cutting, the contact part of this container and a floor surface increases, and stability can be improved more.

  As the material of the packaging material to be used, any material used for packaging containers (particularly standing pouches) can be used, and there is no particular limitation, but preferred examples include nylon, polyethylene, polyethylene terephthalate and the like. Also, a laminate film obtained by appropriately laminating these may be used. The thickness of the packaging material can be appropriately designed within a range not losing the characteristics of the standing pouch, and is not particularly limited, but can be about 100 to 200 μm.

  What is filled into the packaging container according to the present invention is preferably a food that may be cooked and / or eaten mainly in the state of being filled in the container. For example, cooked rice containing alpha rice (white rice, rice bran, red rice, mixed rice, etc.), noodles containing dried noodles (ramen, buckwheat, udon, etc.), stews (curry, hayashi, stew etc.), soups (miso soup) , Pork soup, various soups, etc.), side dishes (meat potatoes, Happo vegetables, etc.) and the like. In addition, as long as the high independence of a container is required, you may use for the foodstuffs and non-foodstuffs (for example, liquid dye etc.) which do not cook and / or eat in the state with which the container was filled.

  According to the present invention as described above, for example, food that may be cooked and / or eaten in a state where it is filled in a container is highly stable even when directly poured with hot water, etc., and the risk of falling down and causing burns is extremely low. There is an effect. In addition, there is an advantage that the stability is high even at the time of eating and the like, and the risk of spilling over is extremely low.

  Embodiments of the present invention will be described below, but the present invention is not limited to these embodiments, and various modifications can be made within the technical idea of the present invention.

  The packaging material is made of nylon / aluminum-deposited PET / LLDPE with a total thickness of 117 μm, and side and bottom members are produced. A standing pouch with a width of 160 mm and a length (length) of 150 mm. It was made of material.

  Then, the two side members, and the two side members and the folded bottom member disposed therebetween were bonded to each other at the respective attachment portions. Then, about the adhesion part of a side surface member and a bottom surface member, 50 mm ((B), 31.3% of full length of horizontal width) was left, and both ends (A) were cut. The cutting was performed so that the adhering portion between the side members was 7 mm above the bottom surface, and a two-stage cutting was performed at a portion 5 mm above the bottom surface (D). Thereby, the adhesion part (C) of the side members became 143 mm (4.7% shorter than full length full length). In addition, processing (notches, chucks, elliptical hook holes, etc.) according to product characteristics was performed to obtain a standing pouch product according to the present invention (FIG. 1).

  The present invention is summarized as follows.

  An object of the present invention is to provide a packaging container (standing pouch) for filling food that is cooked and / or eaten mainly in a state of being filled in a container with a simple structure and high self-supporting property. To do.

  In the stunting pouch in which the two side members and the folded bottom member disposed between the two side members are attached at the attaching portion, both ends of the attaching portions of the side member and the bottom member are obliquely upward from the bottom of the bag. The length of the uncut portion of the attached portion is 30 to 35% of the width of the bag, and the length of the side-attached portion is 3% longer than the length of the bag by cutting. The above problem is solved by configuring the packaging container so as to be shorter by 5%.
