Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a roof-shaped paper container for selling beverage liquids, particularly highly permeable liquids, and is particularly concerned with roof-shaped paper containers in which a multilayer film is laminated on the inside of the container. This relates to paper containers.

[Prior Art] Conventionally, as shown in FIG. 5, this type of paper container has a series of perforations attached to the folded piece 3 of the roof-shaped upper part 2 formed on the container body 1 and the overlapping pieces 4 on the left and right sides of the folded piece 3 to facilitate opening. After making the perforation 5, tear the upper end sealing part 6 of the roof-shaped upper part 2 with the fingertips of both hands and peel it off.
The perforation was torn by pressing the top or bottom of the folding piece 3, and the folded piece 3 under the perforation was pulled out.

With the conventional structure described above, it takes a lot of effort to reliably tear the perforations, and it may not be possible to tear the paper cleanly.

[Problems to be Solved by the Invention] An object of the present invention is to provide a roof-shaped paper container in which the tearing operation is performed smoothly and reliably, and which can be easily opened while maintaining sealing performance.

[Means for Solving the Problems] The means of the present invention is to form an elongated, endless half-cut line that does not reach the multilayer film on the back side of the container at the palm part of the roof-shaped upper part of the container body formed from a web made of paper and a multilayer film. The endless half-cut line is almost straight on the left and right overlapping pieces on the back of the palm part, and it is an arcuate shape that curves downward on the folded piece between the two overlapping pieces, and the half-cut line of one overlapping piece is on the front side. It was applied across the side slope, and the part surrounded by the endless half-cut line was made into a torn piece.

[Example] A specific example of the roof-shaped paper container according to the present invention will be described with reference to FIGS. 1 to 4.

In the figure, 1 is the main body of the container, and the upper end of the roof-shaped upper part 2 is a sealing part 6.

In the present invention, tear pieces 8 for opening are provided by making a series of long and narrow endless half-cuts 7 across the folded piece 3 of the roof-shaped upper part 2 and the overlapping pieces 4 on the left and right sides of the folded piece 3, leaving the multilayer film intact.

The illustrated half cut 7 is formed across the inclined surface 9 on the front side of the overlapping piece 4 to make tearing the tearing piece 8 easier.

[Function] As shown in Fig. 3, the bag is opened by tearing the torn piece, and the folded piece underneath is pulled out and used as a spout.
(See Figure 4) [Effects of the invention] According to the invention, the seal can be opened extremely easily and reliably without impairing the sealing performance, and the half cuts are made on the folded piece and the overlapped piece inside the palm part. Because there is
There is no risk of it being accidentally torn, and it will not interfere with its function as a spout.

Claims (1)

[Scope of utility model registration request] An elongated, endless half-cut line that does not reach the multilayer film on the back side of the container is made on the palm part of the roof-shaped upper part of the container body, which is formed from a web made of paper and a multilayer film. On the overlapping piece, it is almost linear, and on the folded piece between both overlapping pieces, it is in a downwardly curved arc shape, and the half-cut line of one of the overlapping pieces is made across the sloped surface on the front side, and is an endless half-cut line. A roof-shaped paper container with the enclosed part cut out into pieces. .
