Problems solved by technology

[0002] Disposable paper cups are widely used because they are hygienic, light, and cheap, but they have defects such as fixed volume, large space occupation, inconvenient carrying, and easy deformation or damage due to extrusion.
For this reason, "CN201220151502.0" discloses a retractable paper cup with corrugated folding lines on the cup body; although this utility model can effectively overcome the above-mentioned defects of traditional paper cups, the cup wall is easily deformed during use, and the cup Poor body rigidity and stability, easy to fall, and easy to break at corrugated folding lines
On this basis, "CN201621269560.8" discloses an improved telescopic paper cup, which is a cup holder used to increase the stability of the cup body on the periphery of the traditional telescopic paper cup; although this utility model is improved compared with the former , but because the cup holder is not compressible, it does not completely solve the defects of large volume and inconvenient portability of traditional paper cups

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as Figure 1~5 As shown, the cup body is composed of a circular cup holder 5 and a cup body fixedly connected with the cup holder. The cup body is composed of a film sleeve 3 with a conical structure, and a plurality of ring sleeves 1 that are placed on the outer surface of the film sleeve in an intermittent arrangement and pasted and fixed. The lower port of the bottom ring sleeve 1 is formed by a cup holder. 5 closed and glued together. The diameter of each collar 1 increases step by step from bottom to top, and the inner diameter of the upper collar 1 is larger than the outer diameter of the lower collar 1 .

[0019] In order to avoid supporting the film cover 3, a plurality of buckle sheets 2 with folded indentation lines 7 on the surface are evenly pasted on the outer wall of each ring cover 1; The positioning pin 4 that mat...

Abstract

The invention discloses a telescopic variable-volume disposable paper cup, belongs to disposable daily supplies, and aims at providing a telescopic disposable paper cup capable of being carried conveniently by compressing the volume. The telescopic variable-volume disposable paper cup comprises a cup formed by a cup seat and a cup body. The cup body is formed by a thin film sleeve (3) of a conic structure and multiple ring sleeves (1) fixed to the outer surface of the thin film sleeve in a sleeving manner according to a discontinuous arrangement manner, and an end opening of the ring sleeve (1) on the lowest portion is sealed by the cup seat (5). The diameters of the ring sleeves (1) are increased step by step from bottom to top, and the inner diameter of each previous level of ring sleeve(1) is larger than the outer diameter of the corresponding next level of ring sleeve (1). The telescopic disposable paper cup is simple in structure, convenient to use, stable in cup shape, good in steadiness and convenient to carry.

Description

technical field [0001] The invention relates to a disposable paper cup, in particular to a retractable disposable paper cup, belonging to daily necessities. Background technique [0002] Disposable paper cups are widely used because they are hygienic, light, and cheap, but they have defects such as fixed volume, large space occupation, inconvenient carrying, and easy deformation or damage due to extrusion. For this reason, "CN201220151502.0" discloses a retractable paper cup with corrugated folding lines on the cup body; although this utility model can effectively overcome the above-mentioned defects of traditional paper cups, the cup wall is easily deformed during use, and the cup The rigidity and stability of the body are poor, it is easy to lodging, and the corrugated folding line is easy to be damaged. On this basis, "CN201621269560.8" discloses an improved telescopic paper cup, which is a cup holder used to increase the stability of the cup body on the periphery of the...
