Description

TECHNICAL FIELD

[0001] The utility model relates to a paper cup, in particular to a paper cup structure with heat insulation, anti-scald and heat preservation effects. BACKGROUND

[0002] The conventional disposable paper cup has a cup bottom bonded to the bottom of a cup body with both ends in an open state, and a cup mouth fold edge folded outwards from the top end of the cup body to facilitate the mouth of a consumer to abut against the cup edge for drinking. However, the conventional paper cup is formed by folding a single layer of paper material, so that the heat insulation effect of the conventional paper cup is poor, and there is no heat-resistant safety mark on the outside of the cup body, so that the user is easily scalded due to the high temperature of the cup body, causing safety problems in use.

[0003] Therefore, based on years of experience in the manufacture, development and design of related products, the present utility model is finally obtained after careful design and evaluation. SUMMARY

[0004] The technical problem to be solved by the present utility model is to provide a paper cup structure with heat insulation and anti-scald effects to solve the above-mentioned problems in the prior art.

[0005] To achieve the above-mentioned purpose, the paper cup structure of the present utility model comprises a cup body made of paper material and a heat insulation cup sleeve. One end of the cup body forms a cup mouth, and the other end forms a cup bottom. A cup edge is provided outside the end edge of the cup mouth. The outer surface of the heat insulation cup sleeve is provided with a plurality of longitudinal protrusions, and a plurality of longitudinal grooves are formed on the inner surface of the heat insulation cup sleeve opposite to the longitudinal protrusions. The heat insulation cup sleeve is provided around the outer surface of the cup body. The top end of the heat insulation cup sleeve abuts against the cup edge to form a positioning structure. The bottom end of the heat insulation cup sleeve is first folded inward to form a thickened portion, and then the inner surface of the thickened portion is combined and fixed to the outer surface of the cup body. In this way, the gap between the inner surface of the heat insulation cup sleeve and the outer surface of the cup body is increased by the thickened portion, so that a heat insulation space is maintained between the heat insulation cup sleeve and the cup body.

[0006] Preferably, two combination portions are formed on the two sides of the heat insulation cup sleeve, and the two combination portions are connected and fixed to each other by adhesive.

[0007] Preferably, the end edge of the thickened portion of the heat insulation cup sleeve is not flush with the cup bottom of the cup body. The thickened portion is higher than the cup bottom, and the inner surface of the thickened portion is connected and fixed to the outer surface of the cup body by adhesive.

[0008] The top end of the heat-insulating cup sleeve abuts against the cup rim of the cup body, and the bottom of the heat-insulating cup sleeve is combined with the outer surface of the cup body through the inwardly folded thickened portion, so that the inner surface of the heat-insulating cup sleeve does not contact the outer surface of the cup body, a heat-insulating space is formed, and the air flow is ensured through the longitudinal grooves, so that when the heat-insulating cup sleeve bears the pressure of the user holding, the inner surface of the heat-insulating cup sleeve can still avoid contacting the outer surface of the cup body through the longitudinal convex portions and the longitudinal grooves, the heat-insulating and heat-preserving effects of the paper cup are achieved, and the quality and convenience of the user holding or drinking are improved.

[0031] To further understand and appreciate the purpose, features and effects of the present invention, please refer to the following [Brief Description of the Figures] for details:

[0032] First, please Figures 1 to 10 As shown, a paper cup structure comprises a cup body 10 made of paper and an insulating cup sleeve 20. One end of the cup body 10 forms a cup mouth 11, and the other end forms a cup bottom 12. The edge of the cup mouth 11 is rolled outward to form a cup edge 111. The outer surface of the insulating cup sleeve 20 is provided with a plurality of longitudinal protrusions 21. At the same time, a plurality of longitudinal grooves 22 are formed on the inner surface of the insulating cup sleeve 20 relative to the longitudinal protrusions 21. Two joints 23 are formed on both sides of the insulating cup sleeve 20. The two joints 23 are connected by adhesive. After being connected and fixed, the heat-insulating cup sleeve 20 is then placed around the outer surface of the cup body 10, wherein the top end of the heat-insulating cup sleeve 20 abuts against the cup edge 111 to form a position, and the bottom end of the heat-insulating cup sleeve 20 is first folded inward to form a thickened portion 24, and then the inner surface of the thickened portion 24 is fixed to the outer surface of the cup body 10 by adhesive bonding, thereby increasing the gap between the inner surface of the heat-insulating cup sleeve 20 and the outer surface of the cup body 10 through the thickened portion 24, so that an insulating space 25 is maintained between the heat-insulating cup sleeve 20 and the cup body 10.

[0033] To further illustrate, the edge of the thickened portion 24 of the heat-insulating cup sleeve 20 is not flush with the cup bottom 12 of the cup body 10 , and in particular, the thickened portion 24 is higher than the cup bottom 12 .

[0034] The structure of the above embodiment can achieve the following benefits: the top of the heat-insulating cup sleeve 20 abuts against the cup edge 111 of the cup body 10, and the bottom of the heat-insulating cup sleeve 20 is connected to the outer surface of the cup body 10 by the inward folded thickened portion 24, so that the inner surface of the heat-insulating cup sleeve 20 does not touch the outer surface of the cup body 10, and a heat-insulating space 25 is formed. Figure 11As shown, the air flow is ensured by the longitudinal groove 22, so that when the heat-insulating cup sleeve 20 bears the pressure of the user holding it, the inner surface of the heat-insulating cup sleeve 20 can still avoid contacting the outer surface of the cup body 10 through the longitudinal convex part 21 and the longitudinal groove 22, achieving the heat-insulating and heat-preserving effect of the paper cup and improving the quality and convenience of the user holding or drinking.

[0035] The above description is only a preferred embodiment of the present application, and cannot limit the scope of the present application; that is, any equivalent changes and modifications made within the scope of the present application should still be within the scope of the present application.
