Technical Field

[0001] This utility model relates to the field of plastic cup technology, specifically to an environmentally friendly cold drink cup. Background Technology

[0002] In daily life, cold drink cups are widely used, and improving insulation is crucial to maintaining the low temperature of beverages. Currently, existing technologies often use raised structures on the outer wall of the cup to enhance insulation, increasing the thickness of the air gap and utilizing air's low thermal conductivity to achieve insulation. However, this design has significant drawbacks. On one hand, the raised surfaces make the cup uneven, resulting in a poor grip and affecting the user experience. On the other hand, irregular raised surfaces detract from the overall aesthetics of the cup, failing to meet consumers' growing aesthetic demands. Therefore, there is an urgent need to design an environmentally friendly cold drink cup that effectively improves insulation without compromising the cup's feel and appearance. Utility Model Content

The receiving space is provided with a first connecting protrusion integral with the inner cup and a second connecting protrusion integral with the outer cup. The first connecting protrusion can engage with the second connecting protrusion to achieve a fixed connection between the inner and outer cups. When the outer cup is fitted over the inner cup, the gap between them greatly isolates the heat transfer, preventing cold drinks inside the inner cup from affecting the hand holding the cup, thus improving the comfort of using the cold drink cup. Simultaneously, the outer cup has a smooth surface, better integration, and is easier to print on, improving the aesthetics of the cold drink cup. Furthermore, producing a hollow plastic cold drink cup in one piece is difficult and costly. The separate design of the inner and outer cups reduces the production difficulty and facilitates the manufacturing process of the cold drink cup. Attached Figure Description

[0022] like Figure 1 and Figure 2 As shown, an environmentally friendly cold drink cup includes: an inner cup 1, with several outwardly protruding first connecting protrusions 2 on the outer wall of the inner cup 1, and a downwardly extending cup rim 3 on the top.

[0023] Among them, such as Figure 4 As shown, the first connecting protrusion 2 is divided into several groups that are evenly distributed along the circumference of the inner cup 1. Each group includes several first connecting protrusions 2, and the several first connecting protrusions 2 in each group are evenly distributed along the height direction of the inner cup 1, so that the first connecting protrusions 2 are evenly distributed on the outer wall of the inner cup 1.

[0024] Preferably, the first connecting protrusion 2 is U-shaped, and the openings of all U-shaped first connecting protrusions 2 face the first direction. In this embodiment, the first connecting protrusion 2 is integrally formed with the inner cup 1 and is arranged in a horizontal position.
