Forming method and cup body structure of paper cup

Abstract

The invention discloses a forming method and a cup body structure of a paper cup. The forming method adopts the forming steps of selecting raw material paper wood, carrying out type setting and die cutting and forming the paper cup, wherein in the step of carrying out type setting and die cutting, a sector cup body cutter die is adopted to carry out die cutting on the raw material paper wood to form sector cup body paper wood in a type setting and material drawing manner of forming an included angle within an angle range of 5 degrees to 45 degrees between the center line of the cup body cutter die and the extension direction of fibers on an outer paper layer; then the sector cup body paper wood is folded in a surrounding manner to be adhered to form a cup body of the paper cup. The forming method can have high flexibility and variability in the type setting and die cutting process by utilizing a manner of changing the included angle, moreover, can simultaneously consider the structural intensity and the durability of the cup body and a cup mouth and has high industrial utilization value.

Description

technical field [0001] The invention relates to a paper cup used for holding food or drink, in particular to a forming method and a cup body structure of a paper cup having good supporting strength and a cup opening which is easy to curl and form. Background technique [0002] The existing disposable paper cup structure generally includes a cup body made of paper materials folded upright and bonded, and a cup bottom sealed and bonded to the bottom of the cup body. The edge surface is covered with a layer of waterproof film. For the specific structure of the existing paper cup structure, you can refer to the patent case of "Paper Cup Structure Improvement" in Taiwan Certificate No. M456142 and the "Cup Body Structure of Paper Cup" in Taiwan Certificate No. M445398. The patent case, and the patent case of Taiwan Certificate No. M361961 "Improved Structure of Paper Cup", the content will not be described in detail. [0003] see Figure 5 As shown, the raw paper material 50 cur...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the problems and limitations of the existing cup body structure due to poor die-cutting method and improper fiber setting of the outer paper layer of the cup body, the insufficient strength of the cup body structure or the difficulty in folding and curling the edge of the cup mouth, The main purpose of the present invention is to propose a method for forming a paper cup with good support strength and easy curling of the cup mouth and its cup body structure
