The invention provides a container, as shown in fig. 1 and fig. 5, comprising a container body 1 and a container cover 2, wherein the container cover 2 is screwed with the container body 1. The container cap 2 further includes an outer cap 21, an inner cap 24, and a sealing ring 242, the sealing ring 242 being installed at the lower end of the inner cap 24, and when the container cap 2 is closed with the container body 1, the sealing ring 242 extends into the container body 1 along with the inner cap 24 and is sealingly pressed against the inner wall of the container body 1.

Specifically, the container cover 2 further comprises a limiting cover 22, the limiting cover 22 is mounted on the outer cover 21, and the limiting cover 22 is driven by the outer cover 21 to move; the limit cover 22 is provided with a clamping and pushing part 222a, the inner cover 24 is provided with a matched clamping and stopping part, the clamping and pushing part 222a moves relative to the clamping and stopping part in the clamping and stopping part, and the clamping and pushing part is provided with a first matching surface 245a and a second matching surface 244 a; in the process that the outer cover 21 is screwed to the container body 1 to be closed or removed from the container body 1, the inner cover 24 always rotates relative to the outer cover 21, the limiting cover 22 moves under the driving of the outer cover 21, and the clamping and pushing part 222a rotates along with the limiting cover 22 to abut against the first matching surface 245a so as to push the inner cover 24 to axially move to extend into the container body 1 or abut against the second matching surface 244a so as to be capable of removing the outer cover 21 from the container body 1. By this structural cooperation, the inner lid 24 rotates relative to the outer lid 21, that is, the inner lid 24 does not rotate together with the outer lid 21 when the outer lid 21 rotates; and the inner lid 24 can also move axially relative to the outer lid 21 by the engagement of the engagement portion with the structure of the engagement portion 222 a. After the outer cap 21 is screwed to the container body 1, the sealing ring 242 extending into the container body 1 along with the inner cap 24 can abut against the inner wall of the container body 1 to seal water, so as to prevent the liquid inside from leaking. When the container cover 2 is opened, the sealing ring 242 on the inner cap 24 can maintain a water-sealed state with the rotation of the outer cap 21 at the beginning, and cannot rotate with the outer cap 21 (i.e., relative rotation between the inner cap 24 and the outer cap 21); until the clamping and pushing part 222a moves to the clamping and stopping part for pushing the inner cover 24 along with the outer cover 21, the clamping and pushing part 222a pushes the clamping and stopping part to drive the inner cover 24 to be separated from the container body 1, thereby achieving the purpose of opening and taking down the container cover 2. In the process, since the inner cap 24 does not rotate together with the outer cap 21, the sealing ring 242 does not rotate relative to the inner wall of the container body 1 to generate friction, and thus abnormal noise of opening the cap is not generated.

In detail, in the process of unscrewing the container cover 2, as shown in fig. 4, since the outer lid 21 is rotated, the inner lid 24 does not rotate with the outer lid 21, but the container cover 2 can be finally separated from the container body 1, when the engaging and pushing portion 222a moves with the stopper lid 22 to abut against the second engagement surface 244a, the container cover 2 needs to be moved upward and pulled out, so that the seal ring 242 of the inner lid 24 is separated from the sealing connection with the container body 1. The outer lid 21 can be screwed to the container body 1 or removed from the container body 1. In this process, the inner cap 24 will not rotate with the outer cap 21, and the pushing portion 222a of the position-limiting cap 22 will rotate with the outer cap 21, so as to drive the pushing portion 222a to move in the locking portion relative to the locking portion. After the pushing portion 222a moves to abut against the second mating surface 244a to generate a stopping action, the outer cover 21 continues to rotate, and under the action of the rotating force of the outer cover 21, the pushing portion 222a generates a force to continue to move axially, so as to pull the second mating surface 244a to move axially, thereby pulling the inner cover 24 to move axially, and removing the container cover 2. On the contrary, when the container lid 2 is to be closed with the container body 1, the inner lid 24 is gradually inserted into the opening of the container body 1, and the sealing ring 242 provided on the inner lid 24 is abutted against the inner wall of the container body 1, and after the outer lid 21 is brought into contact with the side wall of the container body 1, the outer lid 21 is rotated to be screwed. In the process of screwing, the sealing ring 242 abuts against the inner wall of the container body 1, and under the matching action of the clamping part and the clamping and pushing part 222a, the inner cover 24 can not rotate along with the outer cover 21 to cover the container cover 2, and in the process, no friction caused by rotation of the sealing ring 242 relative to the inner wall of the container body 1 exists, and no abnormal sound is generated.

If the liquid inside the container body 1 has a high temperature and the internal pressure is too high during the opening of the container lid 2, the inner lid 24 will be pulled out from the opening of the container body 1 and will also generate abnormal noise. To avoid the generation of abnormal noise in such a state, it is more preferable that, in one embodiment, the inner lid 24 is provided with the air vent hole 243, and the stopper lid 22 is provided with the blocking portion 221; when the outer cover 21 is screwed on the container body 1 to be covered, the plugging part 221 plugs the exhaust through hole 243, and in the process that the outer cover 21 is screwed on the container body 1 to be taken down from the container body 1, the movement of the limiting cover 22 relatively far away from the inner cover 24 drives the plugging part 221 to open the exhaust through hole 243. By providing the vent through hole 243 and the closing portion 221 which are engaged with each other, the closing portion 221 can close the vent through hole 243 in order to prevent the liquid inside from leaking from the vent through hole 243 when the opening of the container body 1 is sealed by the sealing ring 242 when the container lid 2 is connected to the container body 1.

When the container lid 2 is unscrewed, the outer lid 21 is lifted up along the axial direction while the outer lid 21 is rotated relative to the container body 1, and before the pushing portion 222a moves relative to the locking portion to abut against the second fitting surface 244a to generate a stopper, the inner lid 24 is fixed relative to the container body 1, so that the inner lid 24 and the outer lid 21 are separated from each other, and the blocking portion 221 is lifted along with the outer lid 21 to release the blocking of the air vent 243 provided in the inner lid 24, thereby opening the air vent 243 to release the air and exhaust the air. By means of the structure matching mode, before the container cover 2 is unscrewed, pressure is released and exhausted through the exhaust through hole 243, after the clamping and pushing part 222a is abutted against the second matching surface 244a, the inner cover 24 and the container body 1 can be disconnected by continuously pulling the container cover 2 upwards, and due to the fact that pressure is released in advance, abnormal sound cannot be caused by the action of pulling the container cover 2 upwards to drive the inner cover 24 and the outer cover 21 to move together.

For a more detailed matching structure of the card pushing portion 222a and the locking portion, the following matching methods can be adopted:

in one embodiment, referring to fig. 2, the position-limiting cover 22 can be fixed on the outer cover 21 and move with the outer cover 21, and on the basis of this, in order to facilitate the engagement of the clamping-pushing portion 222a and the clamping-stopping portion, the position-limiting cover 22 is provided with a position-limiting groove 222 along the axial direction, and the inner cover 24 at least partially extends into the position-limiting groove 222. The inner cap 24 includes a shoulder 245 and a stopping step 244 arranged at intervals, and a clamping part is formed between the shoulder 245 and the stopping step 244; the first mating surface 245a is disposed on the shoulder 245, and the second mating surface 244a is disposed on the stopping step 244. That is, the clamping and pushing portion 222a disposed on the limiting cover 22 at least partially extends into the clamping and stopping portion, and along the axial direction, the clamping and pushing portion 222a is disposed in a groove formed between the shoulder 245 and the stopping step 244, and when the outer cover 21 drives the limiting cover 22 to rotate therewith and move relative to the inner cover 24, the clamping and pushing portion 222a can rotate in the groove and move along the axial direction, until the clamping and pushing portion 222a abuts against the first matching surface 245a or the second matching surface 244a, so as to open or close the container cover 2.

Alternatively, in the structural engagement of the stopper cover 22 fixedly connected to the outer cover 21, the engaging pushing portion 222a and the engaging portion may be engaged with each other in the following manner: the clamping and pushing part 222a is an annular part and is detachably connected with the limit cover 22; the clamping part is a mounting groove arranged on the inner cover 24, the mounting groove is annular, and the mounting groove surrounds the outer wall surface of the inner cover 24. The stopper 222a is fitted around the locking portion and slides up and down while rotating along the locking portion as the stopper cover 22 rotates. That is, the stopper cap 22 fixedly connected to the outer cap 21 can be rotated when the outer cap 21 is driven to rotate, and the annular stopper 222a is engaged with the locking portion, so that the stopper cap 22 can be rotated along with the annular stopper 222a, and the stopper cap can be rotated about the axial center of the locking portion and slid upward and downward along the axial center while the stopper 222a is rotated about the axial center of the locking portion, thereby forming a movement pattern of spirally ascending or descending.

Further alternatively, the engaging portions of the engaging pushing portion 222a and the engaging portion may be: the limit cover 22 is fixed on the outer cover 21 and moves along with the outer cover 21; the clamping and pushing parts 222a are stop protrusions on the limiting cover 22 and are symmetrically arranged along the axial direction of the container cover 2; the clamping and stopping part is a sliding groove on the inner cover 24, the sliding groove is spirally arranged on the side wall of the inner cover 24, the clamping and pushing part 222a at least partially extends into the sliding groove and is in sliding connection with the sliding groove, and the first matching surface 245a and the second matching surface 244a are respectively arranged on the inner side walls at two ends in the extending direction of the sliding groove; the second mating surface 244a is disposed above the first mating surface 245a along the axial direction. The card that is about to cooperate pushes away portion 222a and block portion and directly sets up the structural style that the protruding and spout of complex backstop to make the backstop protruding can follow the extending direction motion of spout, and in order to realize enclosing cover 21 and inner cup 24's cooperation, so directly set up the spout into spiral helicine structure, so that when enclosing cover 21 rotates relative to inner cup 24, directly can realize enclosing cover 21 pivoted while the axial is ascending or the motion that descends, simple structure, cooperation structural stability is better.

Optionally, in the structure matching that the card pushing portion 222a is matched with the locking portion so that the card pushing portion 222a can move along the sliding groove to abut against the first mating surface 245a or the second mating surface 244a, in order to facilitate the installation of the two, the card pushing portion 222a is provided with a protruding structure protruding from the position-limiting cover 22, and the protruding structure can elastically deform; under the effect of the elastic deformation of the convex structure, the convex structure is clamped in the sliding groove in a sliding way and can move along the sliding groove.

In another embodiment, the position limiting cover 22 is rotatably sleeved on the outer cover 21, and in this structure, in order to realize the mutual movement between the inner cover 24 and the outer cover 21, the cooperation between the clamping and pushing part 222a and the clamping and stopping part is as follows: the card pushing part 222a is a stop bulge arranged on the limit cover 22; the stop portion is a groove structure formed on the outer cover 21, and the stopper protrusion at least partially extends into the groove structure, so that the stopper protrusion can move in the groove structure along the axial direction of the container cover 2. By the rotational connection of the position-limiting cover 22 and the outer cover 21, the inner cover 24 connected to the position-limiting cover 22 does not rotate when the outer cover 21 is unscrewed or screwed, thereby preventing the seal ring 242 provided thereon from rotating relative to the side wall of the container body 1 to generate friction. In addition, during the rotation of the outer cap 21, the position-limiting cover 22 moves along the axial direction of the container cover 2 along with the rotation of the outer cap 21 as the outer cap 21 is spirally raised or lowered, and the locking portion 222a is driven to slide in the locking portion, so that the inner cap 24 and the outer cap 21 are movably engaged with each other.

It should be emphasized that, in the matching structure of the clamping and pushing part 222a and the clamping and stopping part, and the limiting cover 22 and the outer cover 21, there are many matching ways, not limited to the above, as long as the outer cover 21 and the inner cover 24 can be arranged, when in use, in the process that the outer cover 21 is screwed to be covered relative to the container body 1 or removed from the container body 1, the inner cover 24 always rotates relative to the outer cover 21, the limiting cover 22 moves under the driving of the outer cover 21, and the clamping and pushing part 222a rotates along with the limiting cover 22 to abut against the first matching surface 245a to push the inner cover 24 to axially move to extend into the container body 1 or abut against the second matching surface 244a to remove the outer cover 21 from the container body 1, which is not limited specifically.

Referring to fig. 2 and 3, the outer cap 21 and the position limiting cap 22 of the container cap 2 of the present application are detachably coupled to facilitate detachment. Specifically, the inner wall of the outer cover 21 is convexly provided with a mounting convex ring 211b, the limit cover 22 is provided with a limit stop 223, and the limit stop 223 is rotatably sleeved on the mounting convex ring 211b or fixedly buckled on the mounting convex ring 211 b. The installation convex ring 211b and the limit stop 223 are arranged, so that the detachable connection of the outer cover 21 and the limit cover 22 is facilitated, and the positioning installation matching is facilitated.

As an embodiment of the present application, referring to fig. 3 and 4, in order to ensure that the sealing ring 242 on the inner cap 24 can maintain a good sealing effect and cannot rotate simultaneously with the outer cap 21 when the container cap 2 is screwed to the container body 1, the container cap 2 further includes an elastic portion 25, and the elastic portion 25 elastically abuts between the outer cap 21 and the inner cap 24; when the outer lid 21 is screwed to the container body 1, the elastic portion 25 is deformed by pressure, and the seal ring 242 maintains a sealed state by the restoring force of the elastic portion 25 before the outer lid 21 is screwed to the container body 1 and removed from the container body 1. Due to the arrangement of the elastic part 25, the water sealing effect of the sealing ring 242 is improved by the elastic force of the elastic part 25 when the inner cover 24 is covered on the container body 1 by the container cover 2, and in the unscrewing process of the container cover 2, the elasticity of the elastic part 25 can ensure that the inner cover 24 can not rotate along with the outer cover 21, and meanwhile, the sealing state is maintained, and abnormal sound of opening is avoided.

In order to avoid shaking between the outer cover 21 and the inner cover 24 when the container cover 2 is pulled upwards, the outer cover 21 is provided with a limiting sleeve 211, and the mounting convex ring 211b is formed by convexly arranging the top of the limiting sleeve 211; the inner cover 24 is slidably sleeved in the limiting sleeve 211. Through the setting of stop collar 211 and the at least partial clearance fit of inner cup 24 to make the in-process of enclosing cover 21 and the relative axial motion of inner cup 24, guarantee both to be in all the time and use the axis to move as the center, and avoid producing and rock, and avoid when closing soon or unscrewing container lid 2, enclosing cover 21 produces skew easily, and increases the degree of difficulty of opening or closing, improves the precision of aiming at.

In addition, the inner lid 24 is provided with a stopper 241 so that a good sealing effect can be obtained when the seal ring 242 on the inner lid 24 seals the fitting gap. In the axial direction, the stopper 241 is located below the position-limiting sleeve 211, and the stopper 241 can be stopped at the lower end surface of the position-limiting sleeve 211 along with the movement of the inner cap 24. Specifically, the stopper 241 has a first contact surface 241a, the stop collar 211 has a second contact surface 211a, and the outer cover 21 moves relative to the inner cover 24 along the axial direction until the first contact surface 241a contacts with the second contact surface 211a, so that the fit gap can be sealed. In the screwing process of the container cover 2, when the stop block 241 moves downwards along with the axial direction of the outer cover 21 until the first abutting surface 241a abuts against the second abutting surface 211a, the pressure on the sealing ring 242 connected to the inner cover 24 can be provided, and the sealing ring 242 has better water sealing effect.
