[0035] In the embodiment, the first inclined surface 310 is arranged on the side wall of the sealing groove 300 close to the center of the lower cover 100, and the other side wall is a flat surface. The top end of the first inclined surface 310 is inclined towards the center of the lower cover 100 so that the diameter of the slot gradually decreases from outside to inside. The bottom end of the upper cover 200 is provided with a second inclined surface 210 matched with the first inclined surface 310.

[0036] Specifically, as shown in Figure 3 When the bottom end of the upper cover 200 is inserted into the sealing groove 300, the outer wall of the bottom end of the upper cover 200 abuts against the flat surface of the sealing groove 300, and the inner wall of the bottom end of the upper cover 200 abuts against the second inclined surface 210, so that the sealing groove 300 is in a state of clamping the upper cover 200 after the interference fit with the bottom end of the upper cover 200.

[0037] In the embodiment, the upper cover 200 is provided with external threads, and the lower cover 100 is provided with internal threads, wherein the sealing groove 300 is located below the internal threads.

[0038] The working principle or working process of the embodiment is as follows: rotating the upper cover 200, with the rotation of the upper cover 200, the bottom end of the upper cover 200 is gradually inserted into the sealing groove 300 along the first inclined surface 310 from the slot of the sealing groove 300, and when the upper cover 200 and the lower cover 100 are in a connected state, the bottom end of the upper cover 200 is completely inserted into the sealing groove 300 and interference fits with the sealing groove 300. The connected state in the embodiment refers to the state that the upper cover 200 and the lower cover 100 are screwed.

[0039] The beneficial effect of the embodiment is that by arranging the sealing groove 300, the interference fit structure is added to the original connection structure of the upper cover 200 and the lower cover 100, which further improves the connection strength and sealing performance between the upper cover 200 and the lower cover 100, and ensures that the upper cover 200 and the lower cover 100 will not leak during transportation due to loosening.

[0040] In addition, the sealing groove 300 is arranged on the upper cover 200, and the upper cover 200 is provided with internal threads, while the lower cover 100 is provided with external threads, and the lower cover 100 is inserted into the upper cover 200.

[0041] Embodiment 2

[0042] Embodiment 2 of a bottle cap, based on embodiment 1, the difference from embodiment 1 is that Figures 4-6As shown, the lower cover 100 is provided with a clamping portion 110, and the upper cover 200 is provided with a fastener 220 which is buckled with the clamping portion 110. When the upper cover 200 and the lower cover 100 are in the connected state, the fastener 220 is buckled with the clamping portion 110. In the embodiment, the fastener 220 is provided with two and symmetrically distributed on both sides of the upper cover 200, and the clamping portion 110 is also provided with the same number and arranged in the corresponding position. In other embodiments, the number of the fastener 220 can be more, and the symmetric arrangement can make the user tighten the upper cover 200, and the fastener 220 can be buckled with the clamping portion 110.

[0043] In the embodiment, as shown, Figure 5 The fastener 220 includes a spring piece portion 221, a connecting portion 222 between both ends of the spring piece portion 221, and a clamping jaw portion 223 arranged at one end of the spring piece portion 221. The connecting portion 222 is connected with the upper cover 200.

[0044] Specifically, the clamping jaw portion 223 is protruding, and the clamping portion 110 is a clamping groove and located at the top end of the side surface of the lower cover 100. Such arrangement can make the clamping jaw portion 223 only fit into the clamping portion 110 when the upper cover 200 and the lower cover 100 are in the connected state, and when the upper cover 200 is installed, the increase of resistance caused by the contact between the clamping jaw portion 223 and the outer surface of the lower cover 100 can be avoided.

[0045] In addition, in the embodiment, the upper cover 200 is provided with an extension portion 230 which is used to fit with the top end of the lower cover 100 when the upper cover 200 and the lower cover 100 are in the connected state, so that the upper cover 200 can cover the lower cover 100. When the extension portion 230 is arranged, the connecting portion 222 can be connected with the extension portion 230, or directly connected with the upper cover 200 by arranging a notch on the extension portion 230.

[0046] In the embodiment, the surface of the spring piece portion 221 is also provided with an anti-skid groove, which is used to increase the friction between the user pressing the spring piece portion 221 and the spring piece portion 221, so that the operation of pressing the spring piece portion is not easy to slip.

[0047] The working principle of the embodiment is: when the upper cover 200 and the lower cover 100 are in the connected state, the claw portion 223 and the clamping portion 110 are in the clamped state, so the upper cover 200 cannot be directly screwed. Therefore, when the upper cover 200 needs to be opened, the elastic sheet portion 221 is first pressed away from the end of the claw portion 223, the elastic sheet portion 221 is deformed and rotated outward at the rotation point of the connecting portion 222, so that the claw portion 223 is separated from the clamping portion 110, thereby releasing the connection between the fastener 220 and the clamping portion 110. Then the user continues to press and twists the upper cover 200, so that the upper cover 200 is separated from the lower cover 100. In the process of opening the cover, in fact, only the user needs to apply an external force to the elastic portion to rotate again to achieve the opening of the upper cover 200. Although the operation condition is increased, in actual operation, there is no obvious difference in operation experience for adult users, which can facilitate adult users to open the cover and avoid children from opening the upper cover 200 to cause accidental ingestion.

[0048] The user can also release the elastic sheet portion 221 after releasing the connection between the fastener 220 and the clamping portion 110 and allowing the claw portion 223 and the clamping portion 110 to be misaligned, and directly hold the outer surface of the upper cover 200 to twist the upper cover 200 to achieve the opening of the upper cover 200.

[0049] The beneficial effects of the embodiment are: through the fastener 220 and the clamping portion 110 provided on the upper cover 200 and the lower cover 100 respectively, the operation condition for opening the upper cover 200 is increased, and accidental ingestion events caused by children because the upper cover 200 is too easy to open are avoided, thereby playing the role of a child lock.
