[0002] In the beverage container industry, traditional double-walled plastic cups typically achieve heat and cold insulation through the gap between the outer and inner plastic cups. The core principle is to use the air gap to reduce heat conduction between the inner and outer layers, thus preventing the outer plastic cup from becoming too hot or too cold when holding hot or cold drinks, improving safety. However, this method has the following drawbacks:

[0003] The internal and external cup locking structure lacks stability and is prone to loosening and falling off during use; the insulation effect of a simple air gap is limited and cannot meet the needs of long-term temperature control; the cup mouth has no sealing structure, and liquid can easily spill from the locking point when tilted; its function is limited and it lacks a cushioning design, making it easy to damage the cup body or cause liquid to slosh when impacted.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] like Figure 1-3As shown, this utility model is a beverage cup, including an outer plastic cup 1 and an inner plastic cup 2. The inner plastic cup 2 is detachably installed inside the outer plastic cup 1, forming a gap 3 between the two. The rim 4 of the inner plastic cup 2 is fastened to the rolled edge 5 of the outer plastic cup 1. The inner wall of the outer plastic cup 1 is provided with a snap-fit ​​protrusion 6, and the outer wall of the inner plastic cup 2 is correspondingly provided with a snap-fit ​​groove 7. The snap-fit ​​protrusion 6 and the snap-fit ​​groove 7 are engaged and connected. The gap 3 is filled with a foamed insulation layer.

[0020] The engagement structure of the buckle protrusion 6 and the buckle groove 7 ensures the connection stability between the inner cup 2 and the outer cup 1, preventing them from falling off during use; the foam insulation layer in the gap 3 can reduce heat conduction, and the combination of air insulation and material insulation improves the temperature control effect.

[0021] In the above solution, the outer wall of the outer plastic cup 1 is provided with anti-slip texture, which is either annular protrusions or wavy grooves. The anti-slip texture increases the friction of the outer wall of the outer cup 1, making it less likely to slip when the user holds it, and is especially suitable for use when holding hot or cold drinks, thus improving safety.

[0022] In the above solution, an annular sealing ring is provided at the bottom of the rim 4 of the inner plastic cup 2, and the annular sealing ring is tightly fitted to the inner wall of the rolled edge 5 of the outer plastic cup 1. The annular sealing ring is made of food-grade silicone material, forming a sealing structure with the outer rolled edge 5 to prevent liquid from overflowing from the cup opening, thus meeting the leak-proof requirements in portable scenarios.

[0023] In the above solution, a handle is fixedly connected to the outer side of the outer plastic cup 1. The handle and the outer plastic cup 1 are either integrally molded or detachably connected. The handle design makes it easy for users to hold, especially suitable for large-capacity beverages or high-temperature liquids, avoiding direct contact with the outer cup body; the integrally molded or detachable structure can adapt to different production processes and usage requirements.

[0024] In the above design, the bottom of the inner plastic cup 2 is provided with a buffer protrusion 8, and the inner wall of the bottom of the outer plastic cup 1 is correspondingly provided with a buffer groove 9. The buffer protrusion 8 and the buffer groove 9 are fitted with a clearance. The fit between the buffer protrusion 8 and the buffer groove 9 can absorb the impact force when the cup is placed or collided, reduce the direct vibration between the inner cup 2 and the outer cup 1, protect the cup structure, and prevent liquid sloshing.

[0025] In the above solution, the foamed insulation layer is made of physically foamed PP material, and the thickness of the insulation layer is 2-5mm. Physically foamed PP has a low thermal conductivity, and the 2-5mm thickness can maximize the insulation effect while ensuring lightweight design. When cold drinks are placed inside, water droplets are less likely to form on its surface, further reducing the coldness of the outer cup and significantly extending the temperature control time compared to traditional air gaps.

[0026] In the above solution, the buckle protrusion 6 is an elastic plastic structure, and the depth of the buckle groove 7 is greater than the height of the buckle protrusion 6. The elastic plastic buckle protrusion 6 can deform when engaged, and the depth of the groove 7 is greater than the height of the protrusion 6, ensuring an interference fit after engagement, further enhancing the firmness of the connection between the inner and outer cups, and preventing accidental detachment.

[0027] Working principle:

[0028] In this type of beverage cup, the inner plastic cup 2 is inserted into the opening of the outer plastic cup 1, with the inner cup rim 4 aligned with the outer rolled rim 5. When pressed down, the buckle protrusion 6 on the inner wall of the outer cup 1 deforms and embeds into the buckle groove 7 on the outer wall of the inner cup 2. When the protrusion 6 crosses the critical point of the groove 7, it elastically recovers and forms a lock, achieving a stable connection between the inner and outer cups.

[0029] The foamed insulation layer inside gap 3 prevents heat transfer between the inner and outer layers through the low thermal conductivity of the insulation material itself, making it difficult for the hot or cold drinks in the inner cup 2 to be conducted to the outside, thus improving the insulation effect compared to traditional air gaps.

[0030] The annular sealing ring at the bottom of the inner cup rim 4 fits tightly against the inner wall of the outer cup roll rim 5, forming a sealing structure to prevent liquid from overflowing from the cup rim; the anti-slip texture on the outer wall of the outer cup 1 increases grip friction and prevents slipping.

[0031] When the cup is bumped or placed down, the buffer protrusion 8 at the bottom of the inner cup 2 and the buffer groove 9 at the bottom of the outer cup 1 are fitted together with a gap. The impact force is dispersed through the contact area between the protrusion and the groove, reducing the damage to the cup body caused by vibration.

[0032] The handle of the outer cup 1 (not shown in the figure) is designed to be easy for users to hold, especially suitable for holding or carrying for a long time; the detachable structure of the inner and outer cups supports individual or combined use, meeting the need for "one cup for two uses", and is also easy to clean and maintain.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
