CUP LID AND CUP

Description

BACKGROUND OF THE INVENTION

The present invention relates to the field of container technologies, and in particular, to a cup lid and a cup.

Most cup lids and cup bodies are separate structures. They achieve opening and closing through a tight fit of sealing rings on the circumferential surface of the cup lid, threaded connection, and other methods. These methods require the use of both hands to open and close the lid, making them particularly unsuitable for environments where one-handed operation is needed, such as in driving and exercising. Furthermore, the environments described above are prone to shaking and vibrations, and the cup is in a completely open state after the cup lid is being opened, such that water in the cup is prone to be spilled from the opening of the cup onto the user or the surroundings, causing inconvenience.

To solve the above problems, some manufacturers have designed a cup lid structure with a main lid and an auxiliary lid, where the main lid covers the opening of the cup body and is provided with a water outlet, and the auxiliary lid is rotatably engaged with the main lid for movably blocking the water outlet. The assembly structure between the auxiliary lid and the main lid is generally characterized in that the auxiliary lid is provided with a buckle, the main lid is provided with a rotating clamping groove, and the rotation of the auxiliary lid is achieved through the movement of the buckle in the rotating clamping groove. However, the forming of the assembly structure is troublesome, and especially the production yield of the rotating clamping groove formed on the main lid is relatively low, resulting in high product cost and low quality.

According to the above solution, in the present invention, the second magnetic part 4, the third magnetic parts 5, and the first magnetic part 3 are respectively arranged on opposite surfaces of the main lid body 1 and the auxiliary lid body 2, where the first end 3a of the first magnetic part 3 magnetically engages with the second magnetic part 4 to serve as the rotating shaft for the rotation of the auxiliary lid body 2, allowing the auxiliary lid body 2 to adhere to the upper surface of the main lid body 1 and cooperates with the main lid body 1 in a rotating lid manner. Meanwhile, each of the third magnetic parts 5 is located on the same circle with the second magnetic part 4 as the center, such that the second end 3b of the first magnetic part 3 magnetically engages with one of the third magnetic parts 5 as the auxiliary lid body 2 rotates, thereby achieving the positioning of the auxiliary lid body 2 after rotating by a certain angle to maintain a corresponding state, i.e., to keep the water outlet 11 open or closed, such that the auxiliary lid body 2 does not get loose, ensuring stable functionality. In the present invention, the magnetic parts are installed on the main lid body 1 and the auxiliary lid body 2 respectively by embedment or grooving, such that the structure is simpler, the processing is easy, and the production yield is high. In the present invention, the first end 3a of the first magnetic part 3 and the second magnetic part 4 serve as the rotating shaft and are arranged between the opposite surfaces of the main lid body 1 and the auxiliary lid body 2, the rotating shaft does not penetrate through the main lid body 1, and only the water outlet 11 of the main lid body 1 can discharge water, such that the problem of water leakage at the position of the rotating shaft of the main lid body 1 can be avoided, and the position of the rotating shaft does not need to be sealed, thereby simplifying the structure and facilitating cleaning.

Specific embodiments of the cup lid are shown below.

The auxiliary lid body 2 is in a circular shape, and the blocking member 21 is integrally connected to the circumferential surface of the auxiliary lid body 2; the upper surface of the main lid body 1 is recessed to form a circular groove 12 matched with the auxiliary lid body 2 and an arc groove 13 located on a circumferential surface of the circular groove 12, and the water outlet 11 is formed in the arc groove 13, preferably in the middle position of the arc groove 13; the auxiliary lid body 2 rotatably fits in the circular groove 12, such that the blocking member 21 movably fits in the circular groove 13. Through the design of the circular groove 12 and the arc groove 13, the movement position of the auxiliary lid body 2 on the main lid body 1 can be defined, such that the auxiliary lid body 2 and the main lid body 1 are coaxial and achieve stable rotation; the arc groove 13 gives way for the movement of the blocking member 21; when a plurality of the third magnetic parts 5 are provided, the product has a plurality of positions; after rotation, the auxiliary lid body 2 is positioned through the attraction between the second end 3b of the first magnetic part 3 and one of the third magnetic parts 5, keeping the auxiliary lid body 2 firmly attached to the upper surface of the main lid body 1. Moreover, with reasonable parameter design, when the blocking member 21 abuts against the ends of the arc groove 13, the corresponding open/closed state of the water outlet 11 is enabled, and the ends of the arc groove 13 define the maximum opening angle or the closed state of the auxiliary lid body 2, thereby facilitating users to switch positions in one operation. As can be seen from the above paragraph, in this embodiment, when the blocking member 21 rotates to the left or right to abut against either end of the arc groove 13, the water outlet 11 is in an open state; when the blocking member 21 is located at the middle position of the arc groove 13, the water outlet 11 is in a closed state.
