Embodiment Construction

[0028] Next, modes for implementing the present invention will be described in detail with reference to the drawings. In addition, in each figure, the same code|symbol is attached|subjected to the same or similar part, and the repeated description is simplified or omitted suitably. In addition, the dimensional ratios of the drawings are not limited to the illustrated ratios.

[0029] The easy-open package according to the embodiment of the present invention is obtained by forming the film 1 into a cylindrical shape, filling the contents, and sealing the film 1 at a predetermined position. As the film 1, polyethylene, polypropylene, polyamide, polyethylene terephthalate, polystyrene, polycarbonate, polyvinyl chloride, polyvinylidene chloride, polyacrylonitrile, vinyl- Various resins such as α-olefin copolymers, ethylene-vinyl acetate copolymers, and ethylene-ethyl acrylate copolymers. The above-mentioned resins may be used alone or in combination of multiple materials. In ad...

Abstract

The present invention provides an easy-opened packaging member which has the following advantages: capability of reliably preventing leakage of contained matter, easy opening, and excellent sanitation in opening. The easy-opened packaging member is provided with a longitudinal sealing part which is obtained through sealing a superposed end on a tubular film that is obtained through bending the film. Furthermore two ends of the easy-opened packaging member are respectively provided with a cross sealing part which is obtained through sealing in a direction that is perpendicular with the longitudinal sealing part. The cross sealing part is formed by a first cross sealing part and a second sealing part. The first cross sealing part is obtained through sealing the end of one side of the tubular film in the whole cross range, and the second cross sealing part is obtained through sealing the end of the other side of the tubular film in the whole cross range. The first cross sealing part and / or the second cross sealing part is provided with a non-sealing area. The non-sealing area bestrides the overlapped end in the cross direction and extends a preset length from the end of the former side in the longitudinal direction. Furthermore the overlapped ends are only sealed longitudinally.

Description

technical field [0001] The present invention relates to an easy-openable package formed using an easy-peel (Easy Peel) film and capable of being easily opened. Background technique [0002] Generally, viscous foods such as mayonnaise, paste (Japanese: フラヮ ペ ス ス ト ), butter, jam, etc. (hereinafter referred to as "viscous body") are filled in the package and transported. [0003] As such a package, for example, it is known to stack two sheets of the inner film and the outer film, to make the inner surface of the inner film and the inner surface of the outer film highly adhesive, and to separate the outer surface of the inner film and the outer film. It is also known to make a double-layer bag package (package) with low adhesion on the outer surface (for example, refer to Patent Document 1), and it is also known to make a flat tubular film into a two-layer stacked shape, and place two opposing films A multilayer bag (packaging body) in which both ends of the bag are closed and...
