Description

Technical Field

[0001] This utility model relates to a paper cup, and more particularly to a heat-insulating paper cup with a groove for heat insulation. Background Technology

[0002] Chinese invention patent CN115258349A discloses a grooved heat-insulating paper cup. Multiple heat-insulating protrusions are fixedly bonded to the outside of the paper cup body to achieve a good heat insulation effect, but they are prone to delamination in high temperature and humid environment. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a heat-insulating paper cup with groove insulation, which provides heat insulation by setting grooves on the outer wall of the cup body or the inner wall of the cup sleeve, and the structure is more reliable.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the heat-insulating paper cup with groove insulation includes a cup body, a cup bottom, and a cup sleeve. The cup sleeve is fitted over the cup body, the cup bottom is connected to the bottom of the cup body, and the upper end of the cup body has an outwardly rolled opening. Multiple grooves are provided at intervals on the outer wall of the cup body and / or the inner wall of the cup sleeve. The grooves are dotted lines or strips. The upper end of the cup sleeve is located below the rolled opening, and the inner wall of the cup sleeve fits against the outer wall of the cup body at the rolled opening.

[0005] In this design, the grooves are pressed out by an indentation mold, eliminating the risk of detachment and making the structure more reliable. The inner wall of the cup sleeve fits snugly against the outer wall of the cup body, and the rolled edge covers the upper end of the cup sleeve, ensuring a complete shape and preventing foreign objects from entering. The grooves form multiple heat insulation cavities, restricting airflow, reducing convective heat loss, and improving the heat insulation effect.

[0006] Preferably, both the cup body and the cup sleeve have seams, and the groove is continuous at the seams.

[0007] In this design, the groove at the seam line is continuously designed to maximize the size of the insulation cavity.

[0008] Preferably, the groove is strip-shaped and connected at both ends to form a ring, and the groove is disposed on the outer wall of the cup body.

[0009] In this design, the indentation forms a groove on the outer wall of the cup, and correspondingly, a raised mark is formed on the inner wall of the cup, which can be used as a scale line to indicate the volume of liquid inside the cup.

[0010] Preferably, the upper end of the cup sleeve abuts against the lower side of the roll opening.

[0011] In this design, the rolled edge structure is reinforced and less prone to deformation, and the position of the sleeve is more uniformly limited by the rolled edge.

[0012] Preferably, the cup body is bonded or tightly fitted to the cup sleeve.

[0013] In this solution, the connection is reliable.

[0014] Preferably, the cup body and the cup sleeve are tapered cylinders with matching tapers, and the inner wall of the cup sleeve fits against the outer wall of the cup body at the bottom of the cup.

[0015] In this design, the grooves have a uniform depth and form a closed heat insulation cavity.

[0016] The beneficial effects of this utility model are as follows: the groove is pressed out by an indentation mold, eliminating the risk of detachment and making the structure more reliable; the inner wall of the cup sleeve fits snugly against the outer wall of the cup body; the rolled edge covers the upper end of the cup sleeve, ensuring a complete shape and preventing foreign objects from entering; the groove forms multiple heat-insulating cavities, restricting airflow, reducing convective heat loss, and improving the heat insulation effect. Therefore, this utility model has substantial features and progress compared with the prior art. Attached Figure Description
