Technical Field
[0001] The utility model relates to the field of hot drink cups, in particular to a heat-resistant polylactic acid milk tea cup. Background Art
[0002] As a biodegradable material, polylactic acid (PLA) has been studied and developed since the 1930s. The original polylactic acid has poor heat resistance, with a glass transition temperature of about 60 °C and a heat distortion temperature of about 58 °C, which limits its application in high-temperature environments.
[0003] At present, scientists have successfully developed heat-resistant polylactic acid. This technology is applied to the milk tea cups in our daily life, making the milk tea cups have higher heat resistance. Currently, drinks such as coffee, juice, pearl milk tea, and various tea drinks are extremely popular. The suitable drinking temperature for some hot drinks is about 55 °C - 65 °C. Some merchants may heat the drinks to a higher temperature to ensure the taste of the drinks. In this case, it is difficult for the drinker to hold the drink cup by hand. Content of the Utility Model
[0004] The main technical problem to be solved by the utility model is to provide a heat-resistant polylactic acid milk tea cup, which can insulate the drink cup body, is convenient for users to hold, and has a good heat insulation effect.
[0005] To achieve the above object, a technical solution adopted by the utility model is: to provide a heat-resistant polylactic acid milk tea cup, including a milk tea cup body and a cup rim cover. The milk tea cup body includes an outer cup body and an inner cup body, wherein:
[0006] A hollow sandwich layer is formed between the outer cup body and the inner cup body. Cup body reinforcing ribs and cup bottom reinforcing ribs are arranged between the outer cup body and the inner cup body. There are four groups of cup body reinforcing ribs staggered and fixedly connected to the outer cup body and the inner cup body in the hollow sandwich layer of the cup wall. There are six cup bottom reinforcing ribs arranged in the hollow sandwich layer of the cup bottom and fixedly connected to the outer cup body and the inner cup body.
[0007] Preferably, the cup body reinforcing ribs are of a segmented arc structure, and the cup bottom reinforcing ribs are of a strip-shaped structure.
[0008] Preferably, a groove for accommodating the cup rim cover is provided at the cup rim of the milk tea cup body. A rotating shaft is fixedly connected above the groove at the cup rim of the milk tea cup body. A rotating seat is fixedly connected above the tail of the cup rim cover. The milk tea cup body is rotationally connected through the rotating shaft and the rotating seat. A hole communicating with the hollow sandwich layer between the outer cup body and the inner cup body is provided below the cup rim cover.
[0009] Preferably, a buckle is provided on the outer cup body. A clamping groove corresponding to the buckle is provided inside the cup rim cover. A cup rim-shaped structure is fixedly connected to the outside of the cup rim cover.
[0010] Preferably, the milk tea cup body and the cup rim cover are made of heat-resistant polylactic acid material.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] The present utility model provides a heat-resistant polylactic acid milk tea cup. By providing a double-layer cup body, with a hollow sandwich between the inner cup body and the outer cup body, the heat transfer is effectively blocked. The hollow part is provided with cup body reinforcing ribs and cup bottom reinforcing ribs to provide support for the cup body and the cup bottom, preventing the cup from deforming when the user holds it. At the same time, a cup rim cover is provided at the cup rim, and a hole connecting the outside and the hollow sandwich is opened below, so that hot water or cold water can be added to the hollow sandwich, and the drink can be heated or cooled through heat transfer.

[0020] Please refer to Figures 1-3 , an embodiment provided by the present utility model:
[0021] A heat-resistant polylactic acid milk tea cup, comprising:
[0022] A milk tea cup body 1 and a cup rim cover 2. The milk tea cup body 1 includes an outer cup body 11 and an inner cup body 12, wherein:
[0023] A hollow sandwich is formed between the outer cup body 11 and the inner cup body 12. A cup body reinforcing rib 13 and a cup bottom reinforcing rib 14 are further arranged between the outer cup body 11 and the inner cup body 12. The cup body reinforcing rib 13 is a segmented arc structure, and the cup bottom reinforcing rib 14 is a strip structure. There are four groups of cup body reinforcing ribs 13 staggered and arranged in the hollow sandwich and fixedly connected to the outer cup body 11 and the inner cup body 12. There are six cup bottom reinforcing ribs 14 arranged in the hollow sandwich at the bottom of the cup and fixedly connected to the outer cup body 11 and the inner cup body 12. By adding the cup body reinforcing rib 13 and the cup bottom reinforcing rib 14, the milk tea cup has higher structural strength, and the milk tea cup will not be deformed when the drinker holds it tightly, affecting the drinker's experience.
[0024] A groove for accommodating the cup rim cover 2 is formed at the cup rim of the milk tea cup body 1. A rotating shaft 222 is fixedly connected above the groove at the cup rim of the milk tea cup body 1. A rotating seat 212 is fixedly connected above the tail of the cup rim cover 2. The milk tea cup body 1 is rotationally connected through the rotating shaft 222 and the rotating seat 212. A hole communicating with the hollow sandwich between the outer cup body 11 and the inner cup body 12 is formed below the cup rim cover 2. A buckle 221 is arranged on the outer cup body 11. A clamping groove 211 corresponding to the buckle 221 is formed inside the cup rim cover 2. A cup rim-shaped structure 213 is fixedly connected to the outside of the cup rim cover 2. An opening directly communicating with the outside is designed for the hollow sandwich inside the milk tea cup, and the drinker can use the opening to inject hot water or cold water to change the temperature of the drink in the cup. The cup rim-shaped structure 213 is added to the outside of the cup rim cover 2 so that the drinker can more conveniently open the cup rim cover 2, and at the same time, it is for the integrity of the cup rim, and a sealing cover can be buckled.
[0025] Both the milk tea cup body 1 and the cup rim cover 2 are made of heat-resistant polylactic acid material. The heat-resistant polylactic acid not only has the biodegradability and environmental friendliness of the original polylactic acid, but also has higher heat resistance.
