Description

The present invention relates to a packaging container that is filled with a non-flowable content or a semi-flowable content and can be easily taken out.

Non-fluid or semi-fluid foods such as pudding, yogurt, jelly, tofu and konjac are filled / packaged in plastic cups, trays, bags and the like. Moreover, it shape | molds from a web-shaped packaging material, is filled with the non-solidified content, is made into a paper container, such as a rectangle which folded the flap and the fin in the container wall, and solidifies or semi-fluidizes the content.
When the contents are solid, the upper part of the container is usually cut with scissors or the like, or is cut along a weakening line (half-cut line), the opening is largely opened, and the solid contents are taken out.

If it is said paper container, the weak line (half cut line), such as a sewing machine line, will be formed in advance in a container top part and a flap, it will tear along a sewing machine line, and will take out the contents from opening.

However, non-fluid or semi-fluid contents cannot be easily and easily removed, and are usually cut with scissors along the sewing machine line, or the top of the container with a knife or scissors. The contents must be taken out.
An object of the present invention is to provide a container in which the contents can be easily taken out from the packaging container filled with the non-fluid contents or the semi-fluid contents.

The packaging container of the present invention forms a web-shaped packaging material with a crease line into a tube shape, vertically seals in the vertical line direction of the tube at both edges of the packaging material, and fills the tubular packaging material from a filling pipe. Fill the contents, transversely seal in the tube transverse direction by sandwiching between the sealing jaw and the opposing jaw, cut the packaging material in the transverse sealing zone, have fins at both ends of the cut transverse sealing zone and flaps at the four corners It is a packaging container obtained by obtaining a preform, folding it along a crease line, folding flaps and fins on the side wall, bottom surface and / or top surface, and forming a polygonal cross section.
Two parallel first weakening lines formed in the center of the largest area of the container wall having a longitudinal seal and formed in the transverse direction to the first ridge line of the container wall, starting from the longitudinal seal;
A second weakening line that continues to the first weakening line and is formed up to a second ridgeline adjacent to the first ridgeline;
An easy-to-cut means provided at a starting point for facilitating the cutting of the first weakening line and the cutting of the first weakening line;
A packaging container filled with a non-flowable content or a semi-flowable content.

In a preferred aspect of the present invention, the second weak line is formed on the same line as the first weak line, and the second ridge line is adjacent to the first ridge line in parallel.

In a preferred aspect of the present invention, the second weak line is formed on the first ridge line perpendicularly to the first weak line, and the second ridge line is adjacent to the first ridge line at right angles.

The packaging container according to the present invention forms a web-shaped packaging material with a crease line into a tube shape, vertically seals in the vertical line direction of the tube at both edges of the packaging material, and fills the tubular packaging material from a filling pipe. Fill the contents, transversely seal in the tube transverse direction by sandwiching between the sealing jaw and the opposing jaw, cut the packaging material in the transverse sealing zone, have fins at both ends of the cut transverse sealing zone and flaps at the four corners This is a packaging container in which a preform is obtained, folded along a crease line, and flaps and fins are folded to a side wall, a bottom surface and / or a top surface and formed into a polygonal cross section.
In this packaging container, there are fins and flaps on the container end surface, and the vertical seal portion is cut vertically on the container wall surface. Therefore, if the fins or flaps are cut, the airtightness of the container can be released, and the web-shaped packaging material is overlapped by the vertical seal portion to expose the container wall cross section.
In the packaging container according to the present invention, the contents become non-flowable or semi-flowable after filling. For example, fluid raw materials such as pudding, yogurt, jelly, tofu, and konjac can be filled in a container and solidified or semi-fluidized by a treatment such as heating.

In the characteristics of the packaging container according to the present invention, two first weakening lines parallel to the first ridge line of the container wall in the transverse direction are formed in the center of the maximum area container wall having the vertical seal. Has been.
