Embodiment 1

[0027] Depend on Figure 1 ~ Figure 3 As shown, a disposable degradable paper cup includes a first cup body 1 and a second cup body 2. The first cup body 1 is a truncated cone-shaped tube with an opening at one end, and the first cup body 1 is close to the small end of the truncated cone. A cup bottom is provided inside, and the second cup body 2 is a tapered cylindrical shape with openings at both ends, and the taper of the first cup body 1 and the second cup body 2 is the same, and the outer diameter of the upper end of the first cup body 1 is larger than The inner diameter of the small end on the second cup body 2, and the outer diameter of the small end on the first cup body 1 is smaller than the inner diameter of the large end on the second cup body 2, so that the second cup body 2 can be sleeved outside the first cup body 1, The inner wall of the large port portion of the second cup body 2 is provided with an inner retaining ring 3, and the inner diameter of the inner re...

Embodiment 2

[0033] A preparation method for preparing the disposable degradable paper cup described in Example 1, comprising the following steps:

[0034] S1. Die-cutting: Load the raw paper into the die-cutting machine, and cut out the paper sheet A for rolling the first cup body and the paper sheet B for rolling the second cup body according to the preset shape respectively. The sector angles of sheet A and sheet B are the same, and the radius of the outer arc of sheet A is greater than the radius of the inner arc of sheet B, and the radius of the outer arc of sheet A is smaller than the radius of the outer arc of sheet B;

[0035] S2. Slitting the cup bottom: put the raw paper into the slitting machine, and cut out the circular cup bottom according to the preset size;

[0036] S3. Slitting the outer retaining ring 4: install the cardboard on the slitting machine, and cut the outer retaining ring 4 according to the preset size;

[0037] S4, rolling paper tube: put the paper sheet A and...

Abstract

The invention discloses a disposable degradable paper cup, which relates to the field of disposable paper cups and solves the problem of single-function disposable paper cups in the prior art. The cup is a frustum-shaped tube with an opening at one end, the first cup is provided with a cup bottom near the small end of the truncated cone, the second cup is a cone-shaped tube with openings at both ends, and the first cup and the The taper of the second cup is the same, the outer diameter of the big end on the first cup is greater than the inner diameter of the small end on the second cup, and the outer diameter of the small end on the first cup is less than the inner diameter of the big end on the second cup, the second cup The body is sleeved outside the first cup body, and an inner stop ring is provided on the inner wall of the large port of the second cup body. The inner diameter of the inner stop ring is larger than the outer diameter of the small end of the first cup body, and the inner diameter of the inner stop ring is smaller than the first The outer diameter of the big end of the second cup body; the present invention can make the disposable paper cup have multiple functions through reasonable combination and addition of auxiliary materials.

Description

technical field [0001] The invention relates to the field of disposable paper cups, in particular to a disposable degradable paper cup and a preparation method thereof. Background technique [0002] Disposable paper cup is a kind of paper cup that is easy to carry and use, and is cheap. It is a common drinking tool in many families and public places. Cutting, sample typesetting, printing, film cutting, disinfection and molding processes are processed, and it is easy to use. [0003] Disposable paper cups in the prior art are generally prepared in a cylindrical shape, and their functions are relatively single. For example, disposable paper cups do not have the effect of insulating heat, and do not have the function of preventing knocking over, so that disposable paper cups are easily damaged when placed on the table. Knocked down, therefore, we propose a disposable degradable paper cup and its preparation method. Contents of the invention [0004] The technical problem to...
