Paper bucket volume variable structure and spiral method thereof

Abstract

The invention discloses a paper bucket volume variable structure. The structure comprises a paper bucket body and is characterized in that the paper bucket body is provided with a spiral structure anda folding structure which is screwed through the spiral structure to increase or reduce the internal space. The structure aims to provide a paper bucket which can obtain different internal spaces byspirally extending or compressing the corresponding height, and the paper bucket variable structure is simple to use and operate and convenient for a user to operate and use.

Description

technical field [0001] The invention relates to a paper barrel folding method, in particular to a paper barrel volume variable structure and a spiral method thereof. Background technique [0002] At present, with the increasing demand of the society to use paper instead of plastic for external packaging products, paper packaging is becoming more and more popular. [0003] However, in terms of paper drum packaging, the problem that paper drums occupy too much space and consume a lot of storage and transportation costs has been to be solved. The core of this problem lies in the fact that the paper barrel packaging currently on the market, such as barreled instant noodle packaging, has an incompressible side wall, and in order to meet the needs of consumers to add a large amount of boiling water when eating the inner instant noodles, the side wall is significantly higher. Due to the actual product height inside, the packaging volume is always in a large state, and the excessiv...

[0003] However, in terms of paper drum packaging, the problem that paper drums occupy too much space and consume a lot of storage and transportation costs has been to be solved.

The core of this problem lies in the fact that the paper barrel packaging currently on the market, such as barreled instant noodle packaging, has an incompressible side wall, and in order to meet the needs of consumers to add a large amount of boiling water when eating the inner instant noodles, the side wall is significantly higher. Due to the actual product height inside, the packaging volume is always in a large state, and the excessively large volume has no use value until consumers get the product

In the storage and transportation of commodities, these excessive volumes will directly cause waste of limited storage and transportation space, resulting in increased commodity costs

[0004] In order to solve the above-mentioned problems, Chinese patent CN203268715U discloses a two-stage instant noodle paper barrel, which specifically discloses an upper barrel body and a lower barrel body, the upper barrel body and the lower barrel body are connected by a flexible paper tube, and the upper barrel body of the lower barrel body There is also a groove on the edge. The above technical solution can significantly improve the increase or decrease of the space of the paper barrel. The problem is that when the upper and lower barrels shrink in size, the length of the flexible paper tube must be basically the same as the overlapping length of the upper and lower barrels. When the upper barrel is erected After the groove, the part of the flexible paper tube will arch out, seriously affecting the use

[0005] Chinese patent CN202208472U discloses a retractable instant noodle paper drum. The side wall of the drum body is set as a telescopic ring, and the volume of the drum body is increased by stretching the telescopic ring. The problem with this method is that when the paper drum is stretched, or After repeated stretching and stretching, the paper-plastic barrel body loses its elasticity due to repeated stretching and compression, and it is not easy to compress after stretching, or the compression volume is limited

The common problem of the above two kinds of retractable paper barrels is that the volume of the increase or decrease cannot be changed according to the needs. Although the expansion ring method can logically realize the selection of the number of expansion rings according to the needs, it is generally easy to stretch if the number of rings is small. Fully stretched, or partially stretched but inconvenient for the user
