Abstract

(57) [Summary] (Corrected) [Problem] In a triangular bag for viscous material, a film configuration that gives priority to the softness of the waist during use cannot be applied to an automatic filling machine, and conversely, The film configuration giving priority to strength has a problem that the film is hard when used, so that it is difficult to draw, and an excellent triangular bag for a viscous body automatic filling machine that solves these problems is provided. SOLUTION: In a package made of a nylon and polyethylene co-extruded film having an opening 2 which can be filled on one side of a bag 1 having a triangular shape, a transparent ink 4 is formed on at least one surface except for a portion near the opening. Was applied.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a triangular bag that contains a viscous material such as cream, opens at the tip, squeezes out the contents, and can be automatically and easily continuously attached to an automatic filling machine. The present invention relates to a triangular bag for an automatic filling machine.

[0002]

[Prior art]

 Conventionally, cream or the like has been manually filled into a viscous body-filled triangular bag, so that a rigid film configuration is selected, giving priority to ease of squeezing during use.For example, a co-extruded film of nylon and polyethylene Configurations have been used. However, with this configuration, a series of automatic filling devices that take out bags one by one, open them, fill the bags with cream, and heat-seal them have no rigidity of the film. I couldn't attach it. On the other hand, if a rigid film structure, for example, a laminated film of a polyethylene terephthalate film (hereinafter referred to as PET) and a linear low-density polyethylene film (hereinafter referred to as LLDPE) can be continuously mounted on an automatic filling device. However, it was too stiff, which led to the drawback that it was difficult to squeeze when using it.

[0003]

[Problems to be solved by the invention]

 Therefore, it cannot be applied to an automatic filling machine with the conventional film configuration that prioritizes the softness of the waist during use, and conversely, the film structure that prioritizes the waist strength is difficult to draw because the packaging film is hard during use. There was a problem.

Therefore, the present invention is to solve the problems of the prior art, and does not impair workability at the time of use, does not hinder the process and operation of the automatic filling machine, and further reduces cost. An object of the present invention is to provide an excellent triangular bag for an automatic filling machine.

[0005]

[MEANS FOR SOLVING THE PROBLEMS] In order to solve the above-mentioned problems, the present invention relates to a nylon and polyethylene co-extruded film structure having an opening that can be filled in one side of a triangular bag. A triangular bag for a viscous body automatic filling machine, characterized in that at least one surface is coated with a transparent ink except for a portion near the opening.

[0006]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a triangular bag for an automatic filling machine according to the present invention. An opening 2 filled with a viscous material such as cream is heat-sealed after filling, which is a triangular bag 1 sealed on two sides of the hypotenuse. An aperture cut line 3 for forming an aperture is cut at the end of the acute angle portion of the main body of the triangular bag 1 when cut during use. In addition, the transparent ink application section 4 applied to at least one side of the triangular bag has not been applied to the region near the filling port side of the triangular bag in order to secure the sealing strength.

When the contents are to be used after filling, the triangular bag 1 is opened from the squeeze port cut line 3 by means such as cutting, and then a base packaged in advance with the contents is inserted into the squeeze port. And squeezing out the viscous material such as cream of the contents.

FIG. 2 is a sectional view taken along the line AA in FIG. 2 is an opening, 5 is a seal, 6 is a base film, and 7 is a transparent ink coating layer. As the base film of No. 6, a co-extruded film formed of nylon and polyethylene is used, giving priority to ease of squeezing during use. For the transparent ink coating layer of No. 7, the so-called medium layer, a urethane resin or a vinyl chloride-vinyl acetate copolymer resin, a mixture of a urethane resin and a vinyl chloride-vinyl acetate copolymer resin, or a polyamide resin and nitrocellulose Any ink is used.

The use of these media layers in the film construction provides the film with a moderate waist and slipperiness and helps to suppress the generation of static electricity.

As the transparent ink, typically, as described above, a urethane resin or a vinyl chloride-vinyl acetate copolymer resin, a mixture of a urethane resin and a vinyl chloride-vinyl acetate copolymer resin, or a polyamide resin and nitrocellulose Although any one of them is used, the invention is not limited to this, and ordinary gravure ink may be used as long as it can impart waist and slipperiness to the bag.

When the triangular bags are put into an automatic filling machine, a series of automatic processes of taking out one by one, opening an opening, filling the contents, and heat sealing the opening are continuously and smoothly performed. It became possible.

[0013]

[Effect of the invention]

 A co-extruded film formed of nylon and polyethylene is used for the film configuration of the triangular bag for the automatic viscous material filling machine according to the present invention, because the viscous material that is the content is easily squeezed out during use. However, a transparent ink coating layer, a so-called medium layer, is further provided on at least one surface of the film surface. This can provide the film with adequate waist and slipperiness. Furthermore, it is possible to suppress the generation of static electricity, and as a result, it can be continuously mounted on the automatic filling machine, thereby leading to a significant cost reduction.
