Corrugated paper cup

Abstract

The invention discloses a corrugated paper cup. An isolation cavity is formed by a corrugated paper layer, so that the fact that the hand of a user is scalded by a hot beverage in a paper cup main body; longitudinal corrugated structures are laterally supported and restrained by horizontal corrugated structures; the horizontal corrugated structures are laterally supported and restrained by the longitudinal corrugated structures; and the sidewalls of the longitudinal corrugated structures and the sidewalls of the horizontal corrugated structures do not easily curve laterally. The longitudinal corrugated structures and the horizontal corrugated structures can perform bending resistance supporting, so that the defect of a traditional corrugated paper cup that a crease is formed along a corrugated structure extension direction, so that bending deformation is formed in the direction vertical to corrugated structures is overcome. The upper surfaces and the lower surfaces of the longitudinal corrugated structures and the horizontal corrugated structures all form planar surfaces, so that the contact area of the paper cup main body and an outer paper layer is enlarged, and the longitudinal corrugated structures and the horizontal corrugated structures are favorably glued onto the paper cup main body and the outer paper layer. A communication ventilation web is formed by the whole corrugated paper layer, and the corrugated paper layer communicates with the outside to perform cold and hot air circulation; and the hot beverage in the paper cup main body is subjected to rapid and natural heat dissipation and cooling. An annular corrugated paper base can be overturned up and down to perform stable and stretched support or to be folded.

Description

technical field [0001] The invention relates to the field of daily life, in particular to a corrugated paper cup. Background technique [0002] In daily life, the structure of corrugated paper cups is well known. For example, the Chinese utility model patent CN201520027990.8 discloses a corrugated paper cup, which includes a cup body, a cup mouth and a cup bottom. A corrugated paper cup holder, the corrugated paper cup holder is provided with an insertion part capable of being inserted into the bottom of the cup, and a clamping part capable of being clamped with the mouth of the cup. The bottom of the cup holder is provided with a through hole. The cup body is provided with a gripping portion, the gripping portion is provided with a gripping hole, and the connection between the gripping portion and the cup body is provided with creases. The cup body is provided with a holding groove for hiding the holding portion. The number of the holding portion and the holding groove i...

Problems solved by technology

[0003] The structure of the aforementioned corrugated paper cups is roughly similar to other corrugated paper cups on the market, and the structural strength of the cup body has not been improved. In the actual use process, the cup body often suffers from poor compression resistance and easy deformation, which brings many troubles
