Description

Technical Field

[0001] The present invention relates to the field of cups, and particularly to a container lid and a container. Background Art

[0002] Most of the water cups in the current market are mainly screw-on lids, that is, the cup body and the cup lid are tightened or unscrewed through a threaded mating structure. Moreover, in order to ensure the sealing performance of the mating position after the cup lid is screwed on and avoid liquid leakage, a water sealing rubber ring is provided at the mating gap between the cup lid and the cup body, and this water sealing rubber ring is arranged on the cup lid. When opening the cup lid, during the process of unscrewing the cup lid, the water sealing rubber ring rotates with the cup lid, thus rubbing against the water blocking part on the inner side of the cup body and generating a squeaking abnormal sound. Summary of the Invention

[0003] An object of the present invention is to provide a container lid and a container, which can ensure the water sealing effect of the screw-on container lid while avoiding abnormal sounds when the container lid is opened, thus affecting the use of users.

[0004] The present invention provides a container lid for rotatably connecting with a container body. The container lid includes an outer lid, an inner lid and a sealing ring; the sealing ring is installed at the lower end of the inner lid, and when the container lid covers the container body, the sealing ring extends into the container body along with the inner lid and tightly abuts against the inner wall of the container body;

[0005] The container lid further includes a limiting lid, the limiting lid is installed on the outer lid, and the limiting lid moves under the drive of the outer lid;

[0006] The limiting lid is provided with a pushing part, the inner lid is provided with a cooperating locking part, the pushing part moves relative to the locking part within the locking part, and the locking part has a first mating surface and a second mating surface;

[0007] During the process that the outer lid is screwed relative to the container body to cover or removed from the container body, the inner lid always rotates relative to the outer lid, the limiting lid moves under the drive of the outer lid, and the pushing part rotates along with the limiting lid to abut against the first mating surface to push the inner lid to axially move into the container body or abut against the second mating surface to be able to remove the outer lid from the container body.

[0008] In a possible design, the inner lid includes a spaced-apart shoulder and a stop step, and the locking part is formed between the shoulder and the stop step;

[0009] The first mating surface is arranged on the shoulder, and the second mating surface is arranged on the stop step.

[0010] In a possible design, the limiting lid is fixed on the outer lid and moves along with the outer lid;

[0011] The card pushing part is annular and detachably connected to the limiting cover;

[0012] The card pushing part is sleeved on the card stopping part, and rotates along with the limiting cover and slides up and down along the side of the card stopping part while rotating.

[0013] In a possible design, the limiting cover is rotatably sleeved on the outer cover;

[0014] The card pushing part is a stop protrusion provided for the limiting cover;

[0015] As the outer cover rotates, the limiting cover moves along the axis direction of the container cover, driving the card pushing part to slide in the card stopping part.

[0016] In a possible design, the limiting cover is fixed on the outer cover and moves along with the outer cover;

[0017] The card pushing part is a stop protrusion and is symmetrically arranged along the axis direction of the container cover;

[0018] The card stopping part is a chute, the chute is spirally arranged on the side wall of the inner cover, at least part of the card pushing part extends into the chute and is slidably connected to it, and the first mating surface and the second mating surface are respectively arranged on the inner side walls at both ends in the extending direction of the chute;

[0019] Along the axis direction, the second mating surface is arranged above the first mating surface.

[0020] In a possible design, the inner cover is provided with an exhaust through hole, and the limiting cover is provided with a blocking part;

[0021] When the outer cover is screwed onto the container body until it is closed, the blocking part blocks the exhaust through hole. During the process of the outer cover being screwed relative to the container body until it is removed from the container body, the relative movement of the limiting cover away from the inner cover drives the blocking part to open the exhaust through hole.

[0022] In a possible design, the container cover further includes an elastic part, and the elastic part elastically abuts between the outer cover and the inner cover;

[0023] When the outer cover is screwed relative to the container body until it is closed, the elastic part is compressed and deformed. Before the outer cover is screwed relative to the container body until it is removed from the container body, under the restoring force of the elastic part, the sealing ring maintains the sealed state.

[0024] In a possible design, the outer cover and the limiting cover are detachably connected;

[0025] The inner wall of the outer cover is convexly provided with an installation convex ring, and the limit cover is provided with a limit stop block, and the limit stop block can be rotatably sleeved on the installation convex ring or fixedly buckled on the installation convex ring.

[0026] In a possible design, the outer cover is provided with a limit sleeve, and the installation convex ring is convexly provided from the top of the limit sleeve;

[0028] In a possible design, the inner cover is provided with a stop block, and along the axial direction, the stop block is located below the limit sleeve, and the stop block can stop at the lower end face of the limit sleeve as the inner cover moves.

[0029] In a possible design, the outer cover includes a detachable top cover and a cover base, and the cover base is fixedly connected or rotatably connected to the limit cover.

[0030] In a possible design, the top cover and the cover base are snap-connected by snap-fastening members, and the snap-fastening members include a first snap and a second snap;

[0031] The first snaps are circumferentially arranged on the side wall of the top cover, the second snaps are circumferentially arranged on the side wall of the cover base, and the top cover and the cover base can rotate relative to each other until the first snaps and the second snaps abut against each other, thereby snap-connecting the top cover and the cover base.

[0032] The present invention also provides a container, including a container body and a container cover, and the container cover is the container cover described in any one of the above.

[0033] The present invention provides a container cover, including a rotatable inner cover and an outer cover. The outer cover is provided with a limit cover, and the limit cover and the inner cover are connected by a set of card-pushing parts and card-stopping parts. When opening the container cover, as the outer cover rotates, the limit cover drives the card-pushing part to rotate with the limit cover until it abuts against the second mating surface and pulls the inner cover to move along the axis of the container cover to be removed from the container body. During this movement process, the inner cover does not rotate with the outer cover, and the sealing ring installed on the inner cover will not have relative rotation and friction with the inner wall of the container body, and thus no abnormal sound will be generated when opening the cover.

[0073] It should be noted that the orientation terms such as "upper", "lower", "left" and "right" described in the embodiments of this application are described from the angles shown in the accompanying drawings, and should not be construed as a limitation on the embodiments of this application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected "above" or "below" another element, it can not only be directly connected "above" or "below" another element, but also be indirectly connected "above" or "below" another element through an intermediate element.

[0074] The present invention provides a container, such as Figure 1 and Figure 5 shown in the figure, comprising a container body 1 and a container lid 2, and the container lid 2 is screwed to the container body 1. The container lid 2 further comprises an outer lid 21, an inner lid 24 and a sealing ring 242. The sealing ring 242 is installed at the lower end of the inner lid 24, and when the container lid 2 covers the container body 1, the sealing ring 242 extends into the container body 1 along with the inner lid 24 and tightly abuts against the inner wall of the container body 1 for sealing.

[0075] Specifically, the container lid 2 further comprises a limit lid 22, the limit lid 22 is installed on the outer lid 21, and the limit lid 22 moves driven by the outer lid 21; the limit lid 22 is provided with a clamping and pushing part 222a, and the inner lid 24 is provided with a matching clamping part. The clamping and pushing part 222a moves relative to the clamping part within the clamping part, and the clamping part has a first mating surface 245a and a second mating surface 244a; during the process that the outer lid 21 is screwed relative to the container body 1 to cover or removed from the container body 1, the inner lid 24 always rotates relative to the outer lid 21, the limit lid 22 moves driven by the outer lid 21, and the clamping and pushing part 222a rotates with the limit lid 22 to abut against the first mating surface 245a to push the inner lid 24 to axially move into the container body 1 or abut against the second mating surface 244a so as to be able to remove the outer lid 21 from the container body 1. Through the cooperation of such a structure, the inner lid 24 rotates relative to the outer lid 21, that is, when the outer lid 21 rotates, the inner lid 24 does not rotate together with the outer lid 21; and under the action of the structural cooperation between the clamping part and the clamping and pushing part 222a, the inner lid 24 can also axially move relative to the outer lid 21. After the outer lid 21 is screwed to the container body 1, the sealing ring 242 extending into the container body 1 along with the inner lid 24 can abut against the inner wall of the container body 1 to achieve water sealing, so as to avoid leakage of the internal liquid. When opening the container lid 2, at the beginning, as the outer lid 21 rotates, the sealing ring 242 on the inner lid 24 can maintain the water sealing state and does not rotate with the outer lid 21 (that is, relative rotation between the inner lid 24 and the outer lid 21); until the clamping and pushing part 222a moves with the outer lid 21 to push the clamping part of the inner lid 24, the clamping part is pushed by the clamping and pushing part 222a to drive the inner lid 24 to disengage from the container body 1, so as to achieve the purpose of opening and removing the container lid 2. And during this process, since the inner lid 24 does not rotate together with the outer lid 21, the sealing ring 242 will not have relative rotation and friction with the inner wall of the container body 1, and thus no abnormal sound will be generated when opening the lid.

[0076] In detail, during the process of unscrewing the container lid 2, with reference to Figure 4As shown, when the outer cover 21 is rotated, since the inner cover 24 does not rotate with the outer cover 21, and in order to enable the container lid 2 to be finally separated from the container body 1, after the card-pushing part 222a moves with the limit cover 22 to abut against the second mating surface 244a, it is necessary to move upward to pull out the container lid 2 so that the sealing ring 242 of the inner cover 24 is disengaged from the sealed connection with the container body 1. Thus, it can be realized that the outer cover 21 is screwed relative to the container body 1 to be closed or removed from the container body 1. During this process, the inner cover 24 never rotates with the outer cover 21, while the card-pushing part 222a provided on the limit cover 22 rotates with the outer cover 21, driving the card-pushing part 222a to move relative to the locking part within the locking part. After the card-pushing part 222a moves to abut against the second mating surface 244a to produce a stopping effect, when the outer cover 21 is continuously rotated, under the rotational force of the outer cover 21, a force for the card-pushing part 222a to continue to move axially is generated, thereby pulling the mating second mating surface 244a to move axially accordingly, and then pulling the inner cover 24 to move axially accordingly to remove the container lid 2. On the contrary, when it is necessary to close the container lid 2 on the container body 1, as the inner cover 24 gradually extends into the opening position of the container body 1, the sealing ring 242 provided on the inner cover 24 can abut against the inner wall of the container body 1, and when the outer cover 21 contacts the side wall of the container body 1, the outer cover 21 is rotated to be tightened. During the tightening process, the sealing ring 242 abuts against the inner wall of the container body 1, and under the cooperative action of the locking part and the card-pushing part 222a, it can be ensured that the inner cover 24 does not rotate with the outer cover 21, thus realizing the closing of the container lid 2. During this process, since there is no friction caused by the rotation of the sealing ring 242 relative to the inner wall of the container body 1, no abnormal noise will be generated.

[0077] During the opening process of the container lid 2, if the liquid temperature inside the container body 1 is relatively high, resulting in excessive internal pressure, when the inner cover 24 is pulled out from the opening position of the container body 1, abnormal noise will also be generated. To avoid generating abnormal noise in such a state, more preferably, in a specific embodiment, the inner cover 24 is provided with an exhaust through hole 243, and the limit cover 22 is provided with a blocking part 221; when the outer cover 21 is screwed onto the container body 1 to be closed, the blocking part 221 blocks the exhaust through hole 243, and during the process of the outer cover 21 being screwed relative to the container body 1 to be removed from the container body 1, the movement of the limit cover 22 relatively away from the inner cover 24 drives the blocking part 221 to open the exhaust through hole 243. Through the arrangement of the cooperative exhaust through hole 243 and the blocking part 221, when the container lid 2 is connected to the container body 1 and the sealing ring 242 seals the opening of the container body 1, in order to prevent the internal liquid from leaking through the exhaust through hole 243, the blocking part 221 can block the exhaust through hole 243.

[0078] When the container lid 2 is unscrewed, during the rotation of the outer lid 21 relative to the container body 1, the outer lid 21 will rise axially. Before the card-pushing part 222a moves relative to the locking part and abuts against the second mating surface 244a to generate a stop, the inner lid 24 is fixed relative to the container body 1, causing the inner lid 24 and the outer lid 21 to move away from each other. As a result, the sealing part 221 rises with the outer lid 21 to release the sealing of the exhaust through-hole 243 provided on the inner lid 24, so as to open the exhaust through-hole 243 and achieve pressure relief and exhaust. Through this form of structural cooperation, the container lid 2 is first pressure-relieved and exhausted through the exhaust through-hole 243 before being unscrewed. After the card-pushing part 222a abuts against the second mating surface 244a, the action of continuing to pull out the container lid 2 upward can disconnect the inner lid 24 from the container body 1. Since the pressure relief is completed in advance, the action of pulling out the container lid 2 upward to drive the inner lid 24 and the outer lid 21 to move together will not cause abnormal noise.

[0079] Among them, for the more detailed cooperation structure between the card-pushing part 222a and the locking part, the following several cooperation methods can be adopted:

[0080] In a specific embodiment, referring to Figure 2 As shown, the limiting lid 22 can be fixed on the outer lid 21 and move with the outer lid 21. On this basis, in order to facilitate the cooperation between the card-pushing part 222a and the locking part, along the axial direction, the limiting lid 22 is provided with a limiting groove 222, and at least part of the inner lid 24 extends into the limiting groove 222. The inner lid 24 includes a shoulder 245 and a stop step 244 arranged at intervals, and a locking part is formed between the shoulder 245 and the stop step 244; a first mating surface 245a is arranged on the shoulder 245, and a second mating surface 244a is arranged on the stop step 244. That is, at least part of the card-pushing part 222a provided on the limiting lid 22 extends into the locking part. Along the axial direction, the card-pushing part 222a is arranged in the groove formed between the shoulder 245 and the stop step 244. When the outer lid 21 drives the limiting lid 22 to rotate and move relative to the inner lid 24, the card-pushing part 222a can rotate in the groove and move along the axial direction until the card-pushing part 222a abuts against the first mating surface 245a or the second mating surface 244a, thereby realizing the opening or closing of the container lid 2.

[0081] Alternatively, in the structural cooperation where the limiting cover 22 is fixedly connected to the outer cover 21, the cooperating card-pushing portion 222a and the card-stopping portion can also adopt the following structural cooperation: The card-pushing portion 222a is a ring-shaped component and is detachably connected to the limiting cover 22; the card-stopping portion is an installation groove provided on the inner cover 24. The installation groove is ring-shaped and surrounds the outer wall surface of the inner cover 24. The card-pushing portion 222a is sleeved on the card-stopping portion and rotates along with the limiting cover 22 while sliding up and down along the card-stopping portion. That is, the card-pushing portion 222a is connected to the limiting cover 22 and sleeved on the card-stopping portion. When the outer cover 21 is driven to rotate, the limiting cover 22 fixedly connected to the outer cover 21 can rotate accordingly. And due to the cooperation between the ring-shaped card-pushing portion 222a and the card-stopping portion, the card-pushing portion 222a can rotate along the axial direction of the card-stopping portion, and at the same time, it can slide up and down along the axis while rotating around the axis of the card-stopping portion, thereby forming a spiral ascending or descending motion form.

[0082] Or, the cooperating card-pushing portion 222a and the card-stopping portion can also be: The limiting cover 22 is fixed on the outer cover 21 and moves along with the outer cover 21; the card-pushing portion 222a is a stop projection on the limiting cover 22 and is symmetrically arranged along the axis direction of the container cover 2; the card-stopping portion is a chute on the inner cover 24. The chute is spirally arranged on the side wall of the inner cover 24. At least a part of the card-pushing portion 222a extends into the chute and is slidably connected thereto. The first mating surface 245a and the second mating surface 244a are respectively arranged on the inner side walls at both ends in the extending direction of the chute; along the axis direction, the second mating surface 244a is arranged above the first mating surface 245a. That is, the cooperating card-pushing portion 222a and the card-stopping portion are directly set in the structural form of a cooperating stop projection and chute, so that the stop projection can move along the extending direction of the chute. And in order to realize the cooperation between the outer cover 21 and the inner cover 24, the chute is directly set in a spiral structure, so that when the outer cover 21 rotates relative to the inner cover 24, the outer cover 21 can directly realize the motion of ascending or descending axially while rotating. The structure is simple and the cooperation structure has good stability.

[0083] Optionally, in the structural cooperation where the card-pushing portion 222a and the card-stopping portion are cooperated so that the card-pushing portion 222a can move along the chute to abut against the first mating surface 245a or the second mating surface 244a, for the convenience of their installation, the card-pushing portion 222a is set as a protruding structure extending from the limiting cover 22. The protruding structure can elastically deform; under the action of the elastic deformation of the protruding structure, the protruding structure is slidably clamped in the chute and can move along the chute. Through the elastic deformation of the protruding structure, it can be clamped in the chute and can move along the chute, thereby realizing the installation of the card-pushing portion 222a and the card-stopping portion through the elastic deformation of the protruding structure itself. This kind of cooperation structure is simple and convenient for the staff to assemble.

[0084] In another specific embodiment, the limiting cover 22 is rotatably sleeved on the outer cover 21. In such a structure, in order to realize the relative movement between the inner cover 24 and the outer cover 21, the cooperation between the card-pushing part 222a and the card-stopping part is as follows: the card-pushing part 222a is a stop protrusion provided on the limiting cover 22; the card-stopping part is a groove structure provided on the outer cover 21, and at least part of the stop protrusion extends into the groove structure so that the stop protrusion can move along the axial direction of the container cover 2 in the groove structure. Through the rotational connection between the limiting cover 22 and the outer cover 21, when the outer cover 21 is unscrewed or screwed tightly, the inner cover 24 connected to the limiting cover 22 will not rotate accordingly, thereby avoiding the relative rotation and friction of the sealing ring 242 provided thereon with the side wall of the container body 1. Moreover, during the rotation of the outer cover 21, as the outer cover 21 spirally rises or descends, the limiting cover 22 moves along the axis direction of the container cover 2 as the outer cover 21 rotates, driving the card-pushing part 222a to slide in the card-stopping part, thereby realizing the movement cooperation between the inner cover 24 and the outer cover 21.

[0085] It should be emphasized here that in the cooperation between the provided card-pushing part 222a and the card-stopping part, and in the cooperation structure between the limiting cover 22 and the outer cover 21, there can be various cooperation methods, not limited to the above several. As long as it can be realized that when the outer cover 21 and the inner cover 24 are provided, during use, when the outer cover 21 is screwed onto 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 drive of the outer cover 21, and the card-pushing part 222a rotates with the limiting cover 22 to abut against the first mating surface 245a to push the inner cover 24 to axially move into the container body 1 or abut against the second mating surface 244a to be able to remove the outer cover 21 from the container body 1, no specific limitation is made here.

[0086] Please refer to Figure 2 and Figure 3 As shown, the outer cover 21 and the limiting cover 22 of the container cover 2 of the present application are detachably connected for easy disassembly. Specifically, an installation convex ring 211b is convexly provided on the inner wall of the outer cover 21, and the limiting cover 22 is provided with a limiting stop block 223. The limiting stop block 223 can be rotatably sleeved on the installation convex ring 211b or fixedly buckled on the installation convex ring 211b. Through the provided installation convex ring 211b and the limiting stop block 223, the detachable connection between the outer cover 21 and the limiting cover 22 is facilitated, and the positioning and installation cooperation are facilitated.

[0087] As a specific embodiment of the present application, refer to Figure 3 and Figure 4As shown, when the container lid 2 is screwed onto the container body 1, in order to ensure that the sealing ring 242 on the inner lid 24 can maintain a good sealing effect and will not rotate simultaneously with the outer lid 21, the container lid 2 further includes an elastic part 25, and the elastic part 25 elastically abuts between the outer lid 21 and the inner lid 24; when the outer lid 21 is screwed relative to the container body 1 until it is closed, the elastic part 25 is compressed and deformed, and before the outer lid 21 is screwed relative to the container body 1 and removed from the container body 1, under the restoring force of the elastic part 25, the sealing ring 242 maintains the sealing state. Through the setting of the elastic part 25, when the inner lid 24 is in the state where the container lid 2 is closed on the container body 1, the water sealing effect of the sealing ring 242 is improved by the elastic force of the elastic part 25, and during the process of unscrewing the container lid 2, the elasticity of the elastic part 25 enables the inner lid 24 not to rotate with the outer lid 21 while maintaining the blocking state, avoiding abnormal noise during opening.

[0088] Among them, in order to avoid shaking between the outer lid 21 and the inner lid 24 when pulling up the container lid 2 upward, the outer lid 21 is provided with a limiting sleeve 211, and the mounting convex ring 211b protrudes from the top of the limiting sleeve 211; the inner lid 24 is slidably sleeved in the limiting sleeve 211. Through the setting of at least partial clearance fit between the limiting sleeve 211 and the inner lid 24, when the outer lid 21 and the inner lid 24 move axially relative to each other, it is ensured that the two always move around the axis, thereby avoiding shaking, and avoiding the outer lid 21 being prone to skew when screwing or unscrewing the container lid 2, which increases the difficulty of opening or closing and improves the alignment accuracy.

[0089] In addition, in order to enable the sealing ring 242 on the inner lid 24 to achieve a better sealing effect when in the sealing fit gap, the inner lid 24 is provided with a stop block 241. Along the axial direction, the stop block 241 is located below the limiting sleeve 211, and the stop block 241 can stop against the lower end face of the limiting sleeve 211 as the inner lid 24 moves. Specifically, the stop block 241 has a first abutting surface 241a, and the limiting sleeve 211 has a second abutting surface 211a. Along the axial direction, when the outer lid 21 moves relative to the inner lid 24 until the first abutting surface 241a abuts against the second abutting surface 211a, the fit gap can be sealed. When the container lid 2 is screwed, when the stop block 241 moves axially downward with the outer lid 21 until the first abutting surface 241a abuts against the second abutting surface 211a, it can provide pressure on the sealing ring 242 connected to the inner lid 24, so that the sealing ring 242 has a better water sealing effect.

[0090] Optionally, referring to Figure 1As shown, in order to facilitate the detachable washing of the container lid 2 and to facilitate the detachable connection between the limit lid 22 and the outer lid 21, the outer lid 21 includes a detachable connection between the top lid 23 and the lid base 213, and the lid base 213 is fixedly connected or rotatably connected to the limit lid 22. When installing the limit lid 22 on the lid base 213, for the convenience of installation, the top lid can be removed first. After installing the limit lid 22 on the lid base 213, the top lid 23 is then connected to the lid base 213, thus facilitating the assembly of the limit lid 22. In order to facilitate the detachable connection between the top lid 23 and the lid base 213, a snap connection form can be adopted between the two. One of the snap connection fitting structures can be that the top lid 23 and the lid base 213 are snap-connected through snap members. The snap members include a first snap 231 and a second snap 212. The first snap 231 is circumferentially arranged on the side wall of the top lid 23, and the second snap 212 is circumferentially arranged on the side wall of the lid base 213. The top lid 23 and the lid base 213 can rotate relative to each other until the first snap 231 abuts against the second snap 212, and the top lid 23 is snap-connected to the lid base 213. Thus, through this form of snap connection, the detachable connection between the limit lid 22 and the outer lid 21 is facilitated.

[0091] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
