Portable telescopic paper cup

Abstract

The invention discloses a portable telescopic paper cup which comprises a cup bottom, a cup stand is fixedly connected to the bottom of the cup bottom, a lower cup body is clamped to the top of the outer wall of the cup bottom, an upper cup body is clamped to the top of the outer wall of the lower cup body, a cup edge is fixedly connected to the top of the outer wall of the upper cup body, and a clamping groove is formed in the top of the outer wall of the cup bottom. A tightening ring is fixedly connected to the bottom of the lower cup body, the bottom of the lower cup body is connected withthe cup bottom in a clamped mode through the formed clamping groove, and the same clamping groove is formed in the top of the outer wall of the lower cup body. The upper cup body is pulled upwards vertically, so that the bottom of the lower cup body moves to the clamping groove in the outer wall of the cup bottom, the bottom of the upper cup body moves to the clamping groove in the outer wall of the lower cup body, the cup cannot be pulled upwards due to the outer diameter difference, the bottoms of the upper cup body and the lower cup body deform inwards to be clamped to the inner wall of theclamping groove through the inward tightening force of the tightening ring, so that molding and fixing can be realized by directly pulling, and the effect of convenience in use is achieved.

Description

technical field [0001] The invention belongs to the technical field of disposable paper cups, in particular to a portable retractable paper cup. Background technique [0002] Disposable paper cup is a kind of paper cup that is easy to carry and use with low price. It is a common drinking tool in many families and public places. [0003] For example, Chinese patent CN207360819U discloses a telescopic variable-volume disposable paper cup. By pulling out the ring sleeves at all levels, and then folding each buckle piece upwards by 180° along the folded indentation line, the positioning pins are snapped in. Positioning the card slot, the film sleeve can be stretched to form a stable cup body. Although the paper cup can be stretched and stretched, and the cup can be supported more firmly, it is cumbersome to use and needs to be adjusted one by one. It is very troublesome to use, and the outer wall of the cup is hot when it is connected to hot water, and the temperature of the wa...

Problems solved by technology

[0004] The purpose of the present invention is to provide an easy-to-carry retractable paper cup to solve the problem that the existing retractable paper cup proposed in the above background technology needs to be snapped together one by one during use. It is very troublesome, and when the cup is connected to hot water, the outer wall is hot, and the temperature of the water in the cup is unknown, which makes it inconvenient to use. It is hot when pouring hot water, and the temperature inside the cup cannot be sensed.
