Lid and container including the same

1. A lid, comprising:

a lid body with a hole;

an elastic sleeve having a bore extending therethrough, a part of the elastic sleeve extending through the hole, the elastic sleeve elastically deformable between a torsional state and a non-torsional state;

an elastic spout extending through the bore of the elastic sleeve, the elastic spout being open when the elastic sleeve is in the non-torsional state, the elastic spout being deformed to close when the elastic sleeve is in the torsional state;

a rotating member rotatably assembled on the lid body and configured for twisting the elastic sleeve to the torsional state to cause the elastic sleeve to press and deform the elastic spout;

a locking member movably mounted on the lid body, the locking member having a locking state, in which the locking member is interlocked with the rotating member to keep the elastic sleeve in the torsional state, and a releasing state, in which the locking member is separated from the rotating member to allow the elastic sleeve to return to the non-torsional state; and

an elastic member positioned between the lid body and the locking member and interacting with the locking member for driving the locking member to remain in the locking state.

2. The lid of claim 1 , wherein the elastic sleeve comprises a first linking part, a twisting part and a second linking part, the first linking part is connected to an end of the twisting part and mounted in linkage with the rotating member, and the second linking part is connected to another end of the twisting part and mounted to the lid body.

3. The lid of claim 2 , wherein the twisting part penetrates the lid body through the hole and configured for twisting and pressing the elastic spout to close.

4. The lid of claim 2 , wherein an inner side of the lid body is provided with an annular convex structure in a circumferential direction of the hole, the twisting part of the elastic sleeve penetrates the annular convex structure and the second linking part of the elastic sleeve is fixed on the annular convex structure by a pressure ring.

5. The lid of claim 4 , wherein the annular convex structure is provided with at least one fixing groove, the second linking part is provided with at least one fixing flange, and the at least one fixing flange is coupled to the at least one fixing groove.

6. The lid of claim 5 , wherein the pressure ring is provided with an extending part pressing on the second linking part, and the pressure ring is threadedly engaged to the annular convex structure.

7. The lid of claim 2 , wherein the rotating member comprises an actuating element and a base, the actuating element is provided with at least one bulge, the base is provided with at least one notch coupled with the at least one bulge, the actuating element is mounted on the base by matching the at least one notch with the at least one bulge.

8. The lid of claim 7 , wherein the first linking part is fixed by the actuating element and the base.

9. The lid of claim 8 , wherein the first linking part is provided with at least one limiting gap and at least one location hole separated from the at least one limiting gap, the actuating element is provided with at least one location bar coupled with the at least one location hole, the at least one location bar is engaged in the at least one location hole, in order to achieve a fixation of the actuating element and the first linking part; the base is provided with at least one limiting bar separated from the at least one notch and coupled with the at least one limiting gap, the at least one limiting bar is engaged in the at least one limiting gap, so that the elastic sleeve can be restricted from rotating along an axis of the base.

10. The lid of claim 7 , wherein a mounting groove is defined in an outer side of the lid body around the hole, the locking member is axially and slidably disposed in the mounting groove, the rotating member is located on the locking member.

11. The lid of claim 10 , wherein a button groove connected to the mounting groove is further defined on the outer side of the lid body, the locking member is provided with a release button located in the button groove, and the release button is configured for driving the rotating member to release from the locking member in the releasing state.

12. The lid of claim 10 , wherein the base is further provided with a plurality of limiting gears on a side toward the locking member, the locking member is provided with a plurality of locking claws that cooperates with the plurality of limiting gears to limit rotation of the base to one direction.

13. The lid of claim 10 , wherein the elastic member is a compression spring disposed in the mounting groove, and one end of the compression spring abuts on the bottom of the mounting groove, and the other end of the compression spring abuts on the locking member and interacts with the locking member.

14. A container comprising the lid of claim 1 and a container body.
