The present invention relates to containers such as boxes, and particularly to containers having a portion that can be easily pierced with a straw or the like.

BACKGROUND OF THE INVENTION Today, packaging bags made of laminated materials containing a layer of puncture-resistant material are used as containers for the sale of beverages, such as drinks. It is desirable to provide these bags with a portion that can be easily pierced with a straw so that the contents can be sucked through the straw, and various attempts have been made to do so. For example, a part of the puncture-resistant material layer constituting the laminated material may be punched out in advance with a punching blade and then bonded to other layers, or a suitable portion may be removed with a punching blade or the like after the laminated material is created. Attempts have been made to provide a straw piercing portion using a half-cut method.

However, all of the above conventional techniques have problems. In other words, in a method in which a part of the puncture-resistant material layer constituting the laminated material is punched out in advance using a punching blade and then laminated to other layers, the puncture-resistant material layer is removed separately from the process of laminating and laminating the film. The puncture-resistant material layer must be perforated in a separate process, especially when the puncture-resistant material layer consists of two or more layers.
After laminating and creating these puncture-resistant material layers,
The holes must be drilled in a separate process and must be bonded to the heat-adhesive resin layer, resulting in poor work efficiency and increased costs. In addition, with the method of half-cutting the appropriate parts with a biku blade after creating the laminated material, there is a problem with the stability of the depth of the half-cut, and it is very difficult to control the thickness of the layer that should be left, and if it is too thin, it will tear during transportation. Moreover, if it is too thick, it becomes difficult to stick a straw through it.

ができないという欠点があつた。 Furthermore, in the method of forming an embossed part on the bag body, although the embossed part has the effect of stopping the tip of the straw from slipping, it does not improve the pierceability of the bag body, so it cannot be easily pierced with a straw. There was a drawback.

As a result of research to achieve the above purpose, the inventor of this invention
The reason why it is not easy to pierce the sheet material such as laminated material that forms the container with a straw is that the strength of the sheet material is high and the tip of the straw slips, making it impossible to concentrate stress. By irradiating the carbon dioxide laser beam, a part of the outer surface can be instantly sublimated and removed, which can reduce the strength of the sheet material, and if the outer surface of the sheet material is embossed to make it uneven, the tip of the straw can be easily removed. We have discovered that it is possible to prevent slippage and concentrate stress.

A container arranged in a sheet material, comprising irregularities formed by embossing on the outer surface of a predetermined portion of a sheet-like material, and an opening formed by removing a part of the outer surface of the predetermined portion by irradiation with a carbon dioxide laser beam. The object of the present invention is to provide a container having a pierceable portion, characterized in that the container has a pierceable portion.

The container configured as described above has irregularities formed by embossing on the outer surface of the sheet-like material that constitutes the container, and a portion of the outer surface is removed by irradiation with carbon dioxide laser light to form an opening, which can be pierced. When you stick a straw into that part, the tip of the straw gets caught in the unevenness caused by embossing or the part removed by carbon dioxide laser light irradiation, making it difficult to slip. It can be concentrated in one area and the straw can be pierced very easily.

Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a self-supporting bag 1 which is an embodiment of the present invention, and the bag has a pierceable portion (hereinafter referred to as a weak portion) 2 that can be easily pierced with a straw, and a heat-sealed portion 3 at the periphery. It has As shown in an enlarged view in FIG. 2, this bag 1 is made of a laminated material 4 that is a flexible sheet-like material. The laminated material 4 is composed of an inner heat-adhesive resin layer 5, an outer puncture-resistant material layer 8 consisting of two layers 6 and 7, and an intermediate metal foil (aluminum foil) 9.

ので、エンボス加工を先に行う方が好ましい。 The weak portion 2 is formed by removing a portion of the outer surface (the puncture-resistant material layer 8 in this example) by irradiating the uneven portion with a carbon dioxide laser beam. and the opening 11 formed therein. Note that burrs 11A are formed around the opening 11 due to the irradiation with the carbon dioxide laser beam, which is effective in preventing the tip of the straw from slipping.
The opening 11 does not need to be a circular hole with a diameter larger than the diameter of the straw to be pierced, but may have a shape that allows the tip of the straw to catch and be pushed open when the straw is pierced. As the shape of the opening 11, for example, those shown in FIGS. 3a-1 can be used. The embossing is done to prevent the tip of the straw from slipping, and it can be done in any shape such as circular or rectangular on an area that is approximately the same size as the maximum dimension of the opening 11, and does not need to be the same shape as the opening 11. . By providing the unevenness 10 by embossing, when it is difficult to accurately insert the tip of the straw into the opening 11, such as when using a thin linear opening 11, the unevenness 10 can be formed in a part of or near the opening 11. Even when the tip of the straw is pressed, the straw hardly slips, and the straw can be placed at the weak point 2.
The action of stabbing becomes easier. Either embossing or carbon dioxide laser light irradiation may be performed first. Note that if carbon dioxide laser light is irradiated after embossing, the surface layer can be easily removed, so it is preferable to perform embossing first.

刺し性材料層の一部が残るようにしてもよい。 Next, an opening 1 is formed in the puncture-resistant material layer 8 of the laminate 4.
1 will be explained. As shown in FIG. 4, the surface of the puncture-resistant material layer 8 is irradiated with carbon dioxide laser light 14 for a predetermined period of time through an aperture mask 12 and a focusing lens 13. Aperture mask 1
2 is made of a material that blocks light, such as stainless steel, tungsten, copper, molybdenum, aluminum, paperboard, etc., and has an opening similar in shape to the opening 11 to be formed in the material layer 8. In this manner, the puncture-resistant material layer 8 is instantaneously sublimated and scattered by the laser beam irradiation, and an opening 11 having a desired shape is formed. At this time, the aluminum foil 9 reflects the carbon dioxide laser beam and is hardly processed. Therefore, even if the irradiation time and intensity of the laser beam changes somewhat, holes will be formed in the aluminum foil 9 and the thermoadhesive resin layer 5. The openings 11 can always be formed with a uniform depth. The opening 11 may be formed at any time before or after bag making, and since the laser beam irradiation time is extremely short, the laser beam irradiation can be performed while continuously feeding the laminated material 4 or the bag 1. The opening 11 can be formed by this. In addition,
In the above embodiment, the opening 11 is formed completely through the puncture-resistant material layer 8, but the laser beam irradiation time is shortened to make the depth of the opening 11 shallow, and the puncture-resistant material layer is formed at the bottom. It may be possible to leave a part of the remaining.

The heat-adhesive resin layer 5 can be made of unstretched low-density polyethylene, unstretched medium-density polyethylene, unstretched high-density polyethylene, unstretched polypropylene, ethylene-vinyl acetate copolymer, Surlyn, or the like. Although the resin layer 5 is shown as a single layer in the drawings, it may be a laminate of the same or different materials.

Paper, nonwoven fabric, cellophane, etc. can be used alone or as a laminate. In the drawings, the puncture-resistant material layer 8 is made up of two layers, for example a nylon layer 6 and a polyester layer 7, but it may instead be made up of a single layer or three or more layers.

る。 In addition, in the above embodiment, a laminated material containing aluminum foil in the middle is used as the sheet-like material for making the bag, and the depth of the opening 11 can be easily uniformized by effectively utilizing the property of aluminum foil that is difficult to be processed by laser. However, the same effect can be obtained even if the aluminum foil is omitted and an olefin resin is used as the thermoadhesive resin layer 5. That is, since the olefin resin allows laser light to pass through it and is hardly processed, the opening 11 can be easily formed only in the puncture-resistant material layer by laser processing. However, the depth of the opening 11 can be made uniform by accurately controlling the laser beam irradiation time without using aluminum foil or olefin resin, so the use of aluminum foil or olefin resin is not suitable for the present invention. It is not essential and can be omitted. Further, the material constituting the sheet-like material can be variously changed, and plastic, paper, nonwoven fabric, etc. may be appropriately laminated or used alone.
Furthermore, the present invention is not limited to the bag having the shape shown in FIG. 1, but can be applied to containers such as bags and boxes of any shape.

As described above, in the container of the present invention, the unevenness 10 is formed by embossing on the outer surface of the sheet-like material constituting the container, and the opening 11 is formed by removing a part of the outer surface by irradiation with carbon dioxide laser light. Since it has a part 2 that can be pierced, even if the tip of the straw does not enter the opening 11 accurately when the straw is inserted into this part 2, the unevenness 10 created by embossing will prevent the tip of the straw from slipping. Therefore, when the straw is pushed in, the tip of the straw can be concentrated at one point in the contact area, and since this part 2 is weakened by the opening 11, it is extremely easy to pierce the straw. I can do it. Moreover, both embossing and carbon dioxide laser light irradiation are extremely easy.
Moreover, since it can be carried out continuously, it can be produced at extremely low cost.
