Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a paper container for powder or granules, and more particularly to a paper container for household powder detergent.
[0002]
[Prior art]
Conventionally, as a container for household powder detergents, the upper end opening of a carton filled with detergent is covered with a moisture-proof sheet, covered with a plastic molding lid, etc., and then opened on the back of the plastic molding lid. In general, a paper carton having a sticking process for forming a mold hinge part and a sealing process for sealing on the front is used. Further, instead of the plastic molding lid, a structure using a paper lid is also used. There is also a description of a molded lid made of a plastic sheet. The technique of using a paper lid instead of the plastic molding lid is apparent from the device described in Japanese Utility Model Laid-Open No. 4-121234.
[0003]
In a light weight carton used for snacks and chocolate confectionery, as a well-known and commonly used technique, as shown in FIG. 4 (A), a folding line for a folding hinge part is formed on the upper back of a vertical cylindrical carton manufactured with paperboard or the like. There is a so-called flip top style carton in which a break line extending from the side face, the front face, and the side face connecting the both ends is provided, the opening is opened using the break line, and the lid portion is opened up using the fold line on the back face. As shown in FIG. 4 (B), as for the breaking line, a so-called zipper style is generally used in which the front portion has two parallel saddle-shaped breaking lines, but the zipper is torn. Since the part is open, the contents are exposed and not suitable for reclosing. FIG. 4A also shows a form in which the inner frame is provided integrally or separately in the carton described above, and a structure that restores the reclosed state to the state before opening is also used in many cases. . Since these flip top style cartons are easy to open and can be reclosed, the flip top style carton is a structure effective as a package for products in which the contents are repeatedly used for a certain period of time or a predetermined amount is used continuously.
[0004]
However, paper cartons used as packaging for heavy products such as powder detergents have strength requirements under harsh conditions such as the strength of the product alone and the strength of the aggregate, the strength against the accumulated load during transportation and storage. Therefore, in a flip-top carton so-called flip-top style carton used for the packaging of lightweight items, breakage from the broken line portion is likely to occur due to swelling of the trunk, and the seat from the broken line portion is also caused by load due to stacking. There was a defect that the carton itself was damaged due to bending.
[0005]
In addition, in a carton having a structure in which an inner frame is integrally provided in a flip top style carton, a considerable dimensional difference is required between the carton body and the inner frame due to restrictions on the pasting process by the machine, and it is difficult to make a close structure, There is a drawback that the re-closing of the lid portion is not stable, and in products such as detergents that are used after a certain period of time, deterioration due to humidity, for example, a state called caking where powder particles such as detergents coagulate has occurred.
[0006]
[Problems to be solved by the invention]
Accordingly, the present invention has been made to solve the above-mentioned problems, and the object of the present invention is a paperboard carton for wrapping heavy items such as detergents, and a so-called open carton that has strength. The goal is to provide a flip top style carton.
