Obliquely overlapped paper cup and manufacturing method thereof

Abstract

The invention relates to a method for manufacturing a paper cup, especially relates to an obliquely overlapped paper cup and a manufacturing method thereof. The invention mainly solves the technical problems that in the prior art, paper cups are all prepared by winding up fan-shaped sheet paper, because the overlap edges of the prepared paper cups are arranged vertically, when the paper cups are unfolded and arranged on roll paper, a gap between every two paper cups is large, and more paper is wasted after cutting, thereby causing a high production cost. The paper cup provided by the invention comprises a paper tape body, the two ends of the unfolded paper tape are respectively provided with an overlap edge, an included angle is formed between the two overlap edges, the upper and lower edges of the paper tape body are respectively an upper arc edge and a lower arc edge, the left and right ends of the paper tape body are wound inwards so as to form a truncated-cone shaped cup body, the two overlap edges are fixed together and then obliquely arranged on the cup body, and a cup bottom is fixed at the lower arc edge. The manufacturing method provided by the invention comprises the steps of carrying out roll paper intaglio preprinting; laminating; carrying out die cutting on paper blanks; forming paper cups by using a disposable paper-cup forming machine, and outputting finished products.

Description

technical field [0001] The invention relates to a manufacturing method of a paper cup, in particular to an obliquely overlapping paper cup and the manufacturing method. Background technique [0002] With the increasing consumption of paper bowls and cups in our country, how to achieve zero waste and reduce the waste of resources is becoming more and more important. Although someone has also proposed a paper-saving method in this regard, it can only save paper, but cannot achieve no waste. A Chinese patent discloses a paper cup and a method and device for making a paper cup (publication number: CN101774286A). Between the ends of the cup, the cup sleeve and the central longitudinal axis of the paper cup are at least sectionally clamped at an angle greater than or equal to 10o, especially between 10o and 25o; between the bottom of the cup and the end opposite to the bottom of the cup, Viewed from the inner space of the cup at least in sections, the cup sleeve is arched inward...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides an obliquely overlapping paper cup and its manufacturing method, which mainly solves the problem that the existing paper cups in the prior art are all made of fan-shaped paper sheets, and since the overlapping edges of the paper cups are all vertical Therefore, when it is unfolded and arranged on the roll paper, the gap between each paper cup is large, so more waste paper is wasted after cutting, resulting in technical problems such as high production cost.
