Abstract

(57) [Problem] To provide a paper container blank plate for forming a paper container that can be easily folded into a flat shape so that used paper containers can be easily collected and recycled. SOLUTION: In a paper container blank plate for forming a paper container having a rectangular cross section in the horizontal direction, the four vertical peripheral surfaces (2, 3, 4, 5) forming the paper container are opposed to each other. Along the center line in the width direction, the two vertical surfaces are continuous from the upper edge to the vertical circumferential surfaces 2 and 4, and are provided up to a height position corresponding to 1/2 of the width a of the bottom side. The folding blank lines 1 for the paper container are constructed by additionally providing the folding lines 34, 35 for folding and the horizontal folding lines 36 for connecting the lower ends of the folding lines 34, 35 in the vertical direction.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a blank plate for a paper container for containing various liquid foods and drinks, tea leaves, spices, and the like.

[0002]

[Prior art]

 As a paper container for containing various liquid foods and drinks, tea leaves, spices, etc., a goebel top type or brick type paper container has been conventionally used. As shown in an enlarged sectional view of FIG. 18, for example, these paper containers are prepared by cutting a laminated sheet obtained by laminating resin layers 29 and 30 of a polyolefin resin or the like on the front and back surfaces of paper 28, respectively. For example, a blank plate for a paper container as shown in FIG. 16 is bent and bonded to form a gobel top type paper container 31 as shown in FIG. 17, or a brick type paper container. Or

[0003]

[Problems to be solved by the device]

 As described above, the blank plate for a paper container is formed by a laminated sheet in which resin layers 29 and 30 of a polyolefin resin or the like are respectively laminated on the front and back surfaces of a paper 28 as shown in FIG. As the paper 28, a paper made from relatively high quality pulp is used. Therefore, collecting and reusing the paper container formed by the paper container blank plate is very effective in saving resources.

[0004] However, in order to collect and recycle the paper container, it is necessary to reduce the cost at the collection stage due to the problem of transportation costs due to the bulky paper container and the trouble of folding the paper container flat. There is a big problem. Therefore, an object of the present invention is to provide a paper container blank plate for forming a paper container in which a used paper container can be easily folded flat.

[0005]

[Means for Solving the Problems]

 The above object is achieved by a paper container blank plate of the present invention described below. That is, the present invention relates to a paper container blank plate for forming a paper container having a rectangular cross section in a direction orthogonal to the axial direction, among four longitudinal peripheral surfaces forming the paper container having the rectangular cross section. Folding in the vertical direction provided on the two surfaces facing each other along the center line in the width direction from the upper edge to a height position corresponding to 1/2 of the width of the bottom side continuous with the vertical peripheral surface. It is composed of a blank plate for a paper container to which a ruled line for folding and a ruled line for folding in the horizontal direction connecting the height positions of the ruled line for folding in the vertical direction are attached.

[0006]

[Action]

 The paper container using the blank plate for a paper container according to the present invention has a vertical folding ruled line that folds the paper container to a height position corresponding to half the width of the bottom side, and then folds the paper container in the horizontal direction. It is possible to fold the bottom of the paper container by valley-folding along the folding ruled lines and fold it into a letter-letter shape. Thus, the used paper container can be folded so that the bottoms of the paper container, which are the most multi-layered parts, do not overlap with each other, so that the paper container can be easily folded into a thinner flat shape.
