[0040] Please see Figures 1 to 12 This embodiment provides a user-friendly cold drink cup, which includes a cup body 1, a cup lid 2, a first connecting arm 31, and a second connecting arm 32.

[0041] like Figure 1-6As shown, the cup body 1 has an upward-opening receiving cavity 11 for holding cold drinks. The cup body 1 has a structure similar to a frustum of a cone, with the top dimension of the cup body 1 being larger than the bottom dimension. The bottom of the cup body 1 has an inwardly recessed fitting groove 12 for engaging with the top of the cup lid 2. The outer wall of the cup body 1 includes a first arc surface 14 and a second arc surface 15 closer to the axis of the cup body 1 than the first arc surface 14. Specifically, at any equal horizontal height, the distance from the first arc surface 14 to the axis of the cup body 1 is greater than the distance from the second arc surface 15 to the axis of the cup body 1. That is, the second arc surface 15 is closer to the inner side of the cup body 1 than the first arc surface 14. This design is mainly for facilitating the installation of the first connecting arm 31 and the second connecting arm 32, as detailed below. The second arc surface 15 has two engaging portions 13, which are used to engage and fix the first connecting arm 31 and the second connecting arm 32, respectively.

[0042] The cup lid 2 is detachably installed on the opening at the top of the cup body 1, thereby sealing the receiving cavity 11. The top of the cup lid 2 is provided with a boss structure 21, and the fitting groove 12 at the bottom of the cup body 1 can engage with the boss structure 21, so that the cup body 1 is limited by the boss structure 21. In use, after removing the cup lid 2 from the opening of the cup body 1, the cup lid 2 can be placed at the bottom of the cup body 1, so that the boss structure 21 on the top of the cup lid 2 inserts into the fitting groove 12. At this time, the cup lid 2 can act as a cup support, thereby increasing the stability of the cup body 1 when placed flat (the bottom size of the cup is small and prone to tilting). The top of the cup lid 2 is provided with a reinforcing annular rib 22, which surrounds the outer periphery of the boss structure 21. The reinforcing annular rib 22 and the boss structure 21 together can improve the rigidity of the cup lid 2 and enhance its resistance to compression.

[0043] The first connecting arm 31 and the second connecting arm 32 are respectively disposed on the outer side of the second arc surface 15 and symmetrically arranged with respect to the centerline of the first arc surface 14. One end of the first connecting arm 31 and one end of the second connecting arm 32 are hinged to the first arc surface 14, thereby allowing the first connecting arm 31 and the second connecting arm 32 to swing relative to the cup body 1 and move closer to each other to cooperate. Figure 1 and 2As shown, the first connecting arm 31 and the second connecting arm 32 can be respectively engaged with the two engaging portions 13, thereby fixing the first connecting arm 31 and the second connecting arm 32 relative to the cup body 1. It can be understood that in this embodiment, one end of the first connecting arm 31 and one end of the second connecting arm 32 can be hinged to the first arc surface 14 of the cup body 1, and the other end of the first connecting arm 31 and the other end of the second connecting arm 32 can be engaged with the engaging portions 13. The first connecting arm 31 is provided with a fastening portion 311, and the second connecting arm 32 is provided with a fastened portion 321. The first connecting arm 31 and the second connecting arm 32 can be mutually engaged through the fastening portion 311 and the fastened portion 321 to form a handle structure, as shown below. Figure 6 As shown, the handle structure allows the user to grip it, making it convenient for the user to move the cold drink cup and avoiding direct contact with the outer wall of the cup body 1, thus solving the problems of existing cold drink cups being cold to the touch and difficult to operate. Specifically, when the first connecting arm 31 and the second connecting arm 32 are disengaged from the engaging part 13, the first connecting arm 31 and the second connecting arm 32 are swung towards each other to a predetermined position between them, so that the engaging part 311 and the engaged part 321 are engaged with each other. At this time, the first connecting arm 31 and the second connecting arm 32 can form a handle structure. Then, by disengaging the engaging part 311 and the engaged part 321, the first connecting arm 31 and the second connecting arm 32 can be moved to their original position and engaged on the engaging part 13.

[0044] As can be seen from the above configuration, when the first connecting arm 31 and the second connecting arm 32 are separated, they can be respectively engaged with the engaging portion 13 on the outer wall of the cup body 1, thereby facilitating the stacking of multiple empty cup bodies 1 in a vertical direction to form a single line, saving space. Figure 8 As shown, when two cold drink cups are used together, the first connecting arm 31 and the second connecting arm 32 of one cold drink cup can be respectively engaged with the second connecting arm 32 and the first connecting arm 31 of the other cold drink cup, thereby making the two cold drink cups more securely connected and less likely to slide apart. Figure 9 As shown, when the three cold drink cups are used together, the first connecting arm 31 and the second connecting arm 32 of the first cold drink cup can be respectively fastened to the second connecting arm 32 of the second cold drink cup and the first connecting arm 31 of the third cold drink cup. The first connecting arm 31 of the second cold drink cup and the second connecting arm 32 of the third cold drink cup can be fastened to each other, so that the three cold drink cups are not easy to slide relative to each other and separate.

[0045] Understandably, when multiple cold drink cups are used to hold cold drinks, the first connecting arm 31 and the second connecting arm 32 of one cold drink cup can respectively engage with the second connecting arm 32 and the first connecting arm 31 of the other cold drink cups, so that the multiple cup bodies 1 can be interlocked together and will not slide apart, thus maintaining stability when placed flat. On the other hand, due to the setting of the fitting groove 12 and the boss structure 21, such as Figure 10 As shown, the bottom of the upper cup body 1 can cooperate with the lower cup lid 2 to achieve multi-layer stacking, making it convenient for transportation, especially for outings or takeout, and very easy to carry. When consumers want to eat, they can unfasten the multiple cold drink cups to take out one or more cups, and the remaining cold drink cups will remain stable. Furthermore, the first connecting arm 31 and the second connecting arm 32 of a single cold drink cup can be fastened together to form a handle structure, which allows consumers to hold the handle structure and support the cup lid 2 while eating, keeping their hands warm and ensuring cleanliness and hygiene.

[0046] This application provides a user-friendly cold drink cup. Multiple cold drink cups can be interlocked by their respective first connecting arms 31 and second connecting arms 32. When multiple cold drink cups are placed together, the cups are stable and can maintain the shape of the cold drink inside the cup body 1. After removing some cold drink cups, the remaining cups can still be interlocked and fixed. Furthermore, the first connecting arms 31 and second connecting arms 32 of a single cold drink cup can be interlocked to form a handle structure, which allows consumers to easily hold the handle structure and hold the cup lid 2 to drink, without chilling their hands, and ensuring cleanliness and hygiene.

[0047] like Figure 7 As shown, preferably, in this embodiment, the fastening part 311 is a buckle protrusion, and the fastened part 321 is a buckle hole that passes through the second connecting arm 32. The buckle protrusion can be inserted into the buckle hole to achieve mutual fastening. Specifically, the latching protrusion includes a latching post 3111 and a latching connector 3112 disposed on the top of the latching post 3111. The radial dimension of the latching post 3111 is smaller than the radial dimension of the latching connector 3112. The latching connector 3112 is provided with an inclined guide surface 3113. When the latching protrusion is inserted into the latching hole, the inclined guide surface 3113 of the latching connector 3112 first contacts the edge of the latching hole. The inclined guide surface 3113 is used to contact the latching hole 321 to guide the latching connector 3112 and the latching post 3111 into the latching hole 321, thereby allowing the latching connector 3112 to pass through the latching hole more smoothly. After passing through, the end of the latching connector 3112 near the latching post 3111 abuts against the edge surface of the latching hole, and the latching post 3111 is located in the latching hole, thereby realizing the latching function. Preferably, in this embodiment, the latching protrusion and the latching hole 321 are respectively provided in two places, so that the connection between the first connecting arm 31 and the second connecting arm 32 is more secure after latching.

[0048] Preferably, when the first connecting arm 31 and the second connecting arm 32 are respectively engaged with the two engaging portions 13, at any equal horizontal height, the axial distances from the outer side of the first connecting arm 31, the outer side of the second connecting arm 32, and the first arc surface 14 to the cup body are equal. That is, after the first connecting arm 31 and the second connecting arm 32 are respectively engaged with the two engaging portions 13, the outer sides of the first connecting arm 31 and the second connecting arm 32 can smoothly transition with the first arc surface 14, thereby making the overall appearance more consistent and making stacking more convenient. With this setting, the first connecting arm 31 and the second connecting arm 32 can fit more closely with the cup body 1, reducing the space occupied and facilitating the interlocking and stacking of multiple cup bodies 1.

[0049] like Figure 11 As shown, specifically, in this embodiment, the first connecting arm 31 and the second connecting arm 32 are basically the same in structure except for the fastening part 311 and the fastened part 321. The first connecting arm 31 and the second connecting arm 32 both include a connecting section 301, a horizontal arm section 302 and a mating section 303. The connecting section 301 and the mating section 303 are respectively disposed at both ends of the horizontal arm section 302. The connecting section 301 is hinged to the outer wall of the first arc surface 14. The mating section 303 is provided with a fastening part 311 or a fastened part 321. The mating section 303 can be snapped onto the fastening part 13. By this arrangement, the overall structure can be made simpler and easier to use. By operating the mating section 303, it can be snapped onto the fastening part 13 or the fastening part 311 and the fastened part 321 can be snapped together.

[0050] In this embodiment, when the first connecting arm 31 and the second connecting arm 32 form a handle structure, the mating section 303 of the first connecting arm 31 and the mating section 303 of the second connecting arm 32 form a gripping part 304 extending in the vertical direction for the user to hold. The horizontal arm section 302 of the first connecting arm 31 and the horizontal arm section 302 of the second connecting arm 32 are curved into an arc structure, thereby making the overall structure stable and firm.

[0051] A ring-shaped mating edge 16 protrudes outward from the opening edge at the top of the cup body 1, and a snap-fit ​​ring 23 is provided on the inner side of the cup lid 2 to snap onto the ring-shaped mating edge 16.

[0052] like Figure 12As shown, the connecting segment 301 is hinged to the edge of the first arc surface 14 via a folded wall portion 305. The folded wall portion 305 extends along a predetermined straight line, wherein the length of the projection of the folded wall portion 305 on the vertical plane is greater than the length of its projection on the horizontal plane. It can be understood that the first connecting arm 31 and the second connecting arm 32 swing relative to the cup body 1 with the folded wall portion 305 as the axis. By employing the aforementioned folded wall portion 305 (the length of the projection of the folded wall portion 305 on the vertical plane is greater than the length of its projection on the horizontal plane), the swing axis of the first connecting arm 31 and the second connecting arm 32 can be made closer to the vertical direction rather than the horizontal direction. Therefore, when the handle structure formed by the first connecting arm 31 and the second connecting arm 32 is subjected to an upward force, it will not swing upward, thereby preventing the cup body 1 from tipping over. The folded wall portion 305 can be a wall structure with a folded line integrally formed with the cup body 1.

[0053] Specifically, in this embodiment, the engaging portion 13 includes two claws 131 disposed opposite to each other on the second arc surface 15, and an engaging groove 132 is formed between the two claws 131, and the first connecting arm 31 and the second connecting arm 32 can be engaged in the engaging groove 132.

[0054] Preferably, a rotation prevention part 121 is formed in the fitting groove 12. The rotation prevention part 121 can cooperate with the boss structure 21, so that when the bottom of the cup body 1 is placed on the top of the cup lid 2, the rotation prevention part 121 can be limited and cooperated with the boss structure 21 to prevent the cup body 1 and the cup lid 2 from rotating relative to each other, thereby improving the safety during use.

[0055] In this embodiment, the cup lid 2 is made by thermoforming a low-temperature resistant hard plastic (such as PP, PET, etc.) and punching the edges. A bent spoon is placed in the center of the inside of the cup lid 2 and placed on the cup body 1 containing the cold drink.

[0056] The cup body 1 is made of low-temperature resistant hard plastic (such as PP or PS injection molding). The first connecting arm 31 and the second connecting arm 32 are respectively snapped onto the outer wall of the cup body 1 so that multiple empty cup bodies 1 can be stacked into a single unit. After filling with cold drinks, the first connecting arms 31 and the second connecting arms 32 on the outer walls of multiple cup bodies 1 are fastened together, the spacing is adjusted, the lid 2 is placed on top, and the multiple units can be stacked for transport.

[0057] This application also provides a cup assembly comprising at least two user-friendly cold drink cups of this embodiment. The first connecting arm 31 and the second connecting arm 32 of one of the cold drink cups are respectively engaged with the second connecting arm 32 and the first connecting arm 31 of the other cold drink cups. The cold drink cups of this cup assembly are less likely to slide relative to each other and separate. This cup assembly possesses all the beneficial effects of the aforementioned cold drink cups, which will not be elaborated upon here.

[0058] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
