Description

Technical Field

[0001] The present application relates to the technical field of containers, and in particular to a container cover and a liquid container. Background Art

[0002] The container cover of the existing liquid container is provided with a push switch, and the container cover can be opened or closed by pressing the switch, and the container cover can be kept in the open or closed state. Since the switch has a short stroke, it is difficult to judge the state of the container cover by observing the switch. Therefore, if the user forgets to close the container cover, he will mistakenly think that the container cover is in the closed state, so that the liquid is easy to flow out of the container when the liquid container is moved, affecting the user's use experience. Utility Model Content

[0003] The present application provides a container cover and a liquid container, which are used to solve the problem that it is difficult for a user to judge the state of the container cover.

[0004] A container cover provided in an embodiment of the present application includes: a cover body, a dust cover, a button and a pushing member, the cover body has a accommodating cavity and a liquid outlet, the dust cover is rotatably connected to the cover body, the dust cover includes a dustproof part and a first pushing part connected to the dustproof part, the first pushing part is plate-shaped, the dustproof part is used to block or open at least part of the liquid outlet, at least part of the button is arranged in the accommodating cavity, the button has a second pushing part, the pushing member is slidably connected to the accommodating cavity, and the pushing member has a plate-shaped third pushing part; wherein the second pushing part can move along a first direction and is used to push the pushing member to slide along a second direction in the accommodating cavity, so that the third pushing part can push the first pushing part to rotate around the cover body.

[0005] In the above scheme, the user can judge whether the container cover is in an open state or a closed state by observing the shape and position of the dust cover, thereby improving the user's experience. Specifically, when the user presses the button to make the button move downward along the first direction, the second push part on the button also moves downward along the first direction, thereby abutting against the push member and pushing the push member to move along the second direction, thereby causing the third push part on the push member to move along the second direction until it abuts against the first push part on the dust cover, and by pushing the first push part, the dust cover is rotated and lifted relative to the cover body. Since the button remains in a pressed state, the third push part remains in a contact support state with the first push part, so the dust cover also remains in a lifted state. Since the first push part and the third push part are both plate-shaped, the contact area when the two abut is large, and the force of the third push part pushing the first push part can be reliably transmitted to the dust cover.

[0006] In a possible design, the first pushing portion is a plate-shaped structure perpendicular to the second direction, and the third pushing portion is a plate-shaped structure perpendicular to the first direction.

[0007] In the above solution, the force of the third pushing part moving along the second direction can directly and reliably act on the first pushing part with less force loss, thereby improving the reliability of the third pushing part pushing the dust cover to rotate and lift.

[0008] In a possible design, the dustproof portion is provided with a rotating shaft at one end close to the first pushing portion, and the rotating shaft is rotatably connected to the cover body; the cross-section of the dustproof cover is L-shaped.

[0009] In the above solution, a rotation groove is provided on the cover body near the liquid outlet, and the rotation shaft is rotationally connected to the rotation groove, thereby ensuring the smoothness and reliability of the rotational connection between the dustproof part and the cover body.

[0010] In a possible design, the pushing member has an inclined power receiving surface, and the second pushing portion has an inclined power output surface. When the button moves along the first direction, the power output surface can abut against the power receiving surface and push the pushing member to slide along the second direction.

[0011] In the above scheme, the inclined power output surface and the inclined power receiving surface abut against each other to change the force transmission direction, so that the button moving in the first direction pushes the pusher to move in the second direction. At the same time, the force transmission through the inclined surface also has the advantages of smooth and reliable force transmission.

[0012] In a possible design, the cover body has guide protrusions arranged at intervals, and guide grooves are formed between the guide protrusions, and the pusher can slide in the guide groove; the guide protrusion includes a limiting portion extending toward the guide groove, and the limiting portion can limit the movement of the pusher along the first direction.

[0013] In the above solution, the guide protrusion can guide the movement of the pusher, so that the pusher moves along a preset route, ensuring that the third pusher accurately abuts against the first pusher and pushes the dust cover to rotate. The limiter can limit the movement of the pusher in the first direction, preventing the pusher from falling off the guide groove, and ensuring the reliability of the container cover.

[0014] In a possible design, the pushing member is provided with a weight-reducing groove.

[0015] In the above solution, the weight-reducing groove can reduce the weight of the pusher, thereby reducing the force required by the second pusher to push the pusher to move, reducing the resistance felt by the user when pressing the button, and thus improving the user experience. At the same time, the weight-reducing groove reduces the raw materials required to produce a pusher, so the provision of the weight-reducing groove can also reduce the production cost of the pusher.

[0016] In a possible design, the container cover also includes an elastic member located in the accommodating cavity; the pushing member is provided with a limiting protrusion, and the side wall of the accommodating cavity is provided with a limiting groove, one end of the elastic member is sleeved on the limiting protrusion, and the other end of the elastic member extends into the limiting groove and abuts against the inner wall of the limiting groove.

[0017] In the above scheme, when the pusher approaches the first pusher along the second direction under the action of the second pusher, the distance between the pusher and the side wall of the accommodating cavity is reduced, and the elastic member is compressed; when the container cover changes from the open state to the closed state, the button moves upward along the first direction, and the second pusher no longer applies a force to the pusher, so the pusher can move in the opposite direction along the second direction under the action of the restoring force of the elastic member, and at this time, the third pusher no longer applies a force to the first pusher, and the dust cover can rotate and fall under the action of gravity. The limiting protrusion and the limiting groove can prevent the elastic member from falling off the pusher, thereby improving the working reliability of the container cover.

[0018] In a possible design, the cover body includes: an upper cover, a lower cover and an inner cover, the upper cover is connected to the lower cover, the inner cover is located between the upper cover and the lower cover, there is the accommodating cavity between the upper cover and the inner cover, and the dust cover is rotatably connected to the lower cover.

[0019] In the above solution, the dust cover is arranged on the lower cover so that the dust cover is located outside the accommodating cavity, which facilitates the installation of the dust cover. The upper cover can limit the rotation range of the dust cover and prevent the dust cover from moving to a position where it cannot rotate and fall from the raised state under the action of gravity.

[0020] In a possible design, the inner cover has a connecting hole connecting the accommodating cavity and the outside, and the third pushing portion can pass through the connecting hole to contact the dust cover.

[0021] In the above solution, the connecting hole is provided so that the pusher can contact the dust cover outside the accommodating cavity, thereby realizing the driving of the dust cover by the pusher. At the same time, the dust cover does not need to extend into the accommodating cavity, reducing the possibility of liquid entering the accommodating cavity.

[0022] An embodiment of the present application provides a liquid container, which includes: a container body and a container cover, wherein the container cover is connected to the container body and the container cover is the container cover described above.

[0023] In the above scheme, the user can judge whether the container cover is in an open state or a closed state by observing the shape and position of the dustproof plate on the container cover, thereby preventing the user from moving the liquid container when the container cover is open, causing the liquid in the container to overflow from the container cover, thereby improving the user's experience.

[0024] It should be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0076] The present application embodiment provides a liquid container, such as Figure 1 As shown, the liquid container includes: a container body 2 and a container cover 1, and the container cover 1 is connected to the container body 2.

[0077] like Figure 1 and Figure 2 As shown, the container body 2 has an opening, and the container cover 1 is connected to one end of the container body 2 having the opening. The container body 2 is used to contain liquid and can also have a heat preservation effect.

[0078] The present embodiment also provides a container cover 1, such as Figure 2 and Figure 3 As shown, the container cover 1 includes: a cover body 11, a dust cover 12, a button 13 and a push member 14, the cover body 11 has a accommodating chamber 11a and a liquid outlet 11b, the dust cover 12 is rotatably connected to the cover body 11, the dust cover 12 includes a dustproof portion 121 and a first push portion 122 connected to the dustproof portion 121, the first push portion 122 is plate-shaped, the dustproof portion 121 is used to block or open at least part of the liquid outlet 11b, at least part of the button 13 is arranged in the accommodating chamber 11a, the button 13 has a second push portion 131, the push member 14 is slidably connected in the accommodating chamber 11a, and the push member 14 has a plate-shaped third push portion 141; wherein the second push portion 131 can move along the first direction X, and is used to push the push member 14 to slide along the second direction Y in the accommodating chamber 11a, so that the third push portion 141 can push the first push portion 122 to rotate around the cover body 11.

[0079] When the user presses the button 13, the container lid 1 opens, and the dust cover 12 rotates and rises relative to the cover body 11 and remains in the raised state. At this time, the container body 2 is tilted, and the liquid in the container body 2 can flow out from the liquid outlet 11b; when the user presses the button 13 again, the container lid 1 is closed, and the dust cover 12 rotates and falls relative to the cover body 11 and remains in the fallen state. At this time, the container body 2 is tilted, and the liquid in the container body 2 cannot flow out from the liquid outlet 11b. Therefore, the user can judge whether the container lid 1 is in the open state or the closed state by observing the shape and position of the dust cover 12, thereby improving the user experience.

[0080] In addition, when the container cover 1 is in a closed state, the dustproof part 121 can cover the liquid outlet 11b to prevent dust from falling in. When the liquid container is a heat preservation container, the dustproof cover 12 can remind the user to prevent the user from forgetting to close the container cover 1 and affecting the heat preservation effect.

[0081] Specifically, Figure 2 and Figure 3 As shown, when the user presses the button 13 to move the button downward along the first direction X, the second push portion 131 on the button 13 also moves downward along the first direction X, thereby abutting against the push member 14 and pushing the push member 14 to move along the second direction Y, thereby causing the third push portion 141 on the push member 14 to move along the second direction Y until it abuts against the first push portion 122 on the dust cover 12, and by pushing the first push portion 122, the dust cover 12 is rotated and lifted relative to the cover body 11. Since the button 13 remains in a pressed state, the third push portion 141 remains in a contact and support state with the first push portion 122, and thus the dust cover 12 also remains in a lifted state.

[0082] Since the first pushing portion 122 and the third pushing portion 141 are both plate-shaped, the contact area between the two when they are in contact is large, and the force of the third pushing portion 141 pushing the first pushing portion 122 can be reliably transmitted to the dust cover 12. At the same time, when the third pushing portion 141 or the first pushing portion 122 slightly deviates from the installation position, the third pushing portion 141 and the first pushing portion 122 can still contact and transmit the force, thereby reducing the precision required for the assembly of the container cover 1 and improving the reliability of the container cover 1.

[0083] More specifically, the cover body 11 also has a liquid inlet 11c connected to the liquid outlet 11c, and the container cover 1 also includes a switch assembly 16. One end of the switch assembly 16 extending into the accommodating cavity 11a is connected to the button 13, and the other end is provided with a sealing gasket 19 capable of blocking or opening the liquid inlet 11c. When the container cover 1 is in a closed state, the sealing gasket 19 seals the liquid inlet 11c to prevent the liquid from flowing out through the liquid inlet 11c and the liquid outlet 11b when the container body 2 is shaken.

[0084] When the user presses the button 13, the button 13 drives the switch assembly 16 to move downward along the first direction X, and the sealing gasket 19 opens the liquid inlet 11c. At the same time, the switch assembly 16 can maintain this state until the user presses the button 13 again, and the switch assembly 16 drives the button 13 to move upward along the first direction X, and the sealing gasket 19 blocks the liquid inlet 11c. Therefore, the container cover 1 can be kept in an open or closed state by providing the switch assembly 16.

[0085] Further, such as Figure 4 As shown, the container cover 1 further includes an elastic member 15 located in the accommodating cavity 11a, one end of the elastic member abuts against the push member 14, and the other end abuts against the side wall of the accommodating cavity 11a. When the push member 14 approaches the first push member 122 along the second direction Y under the action of the second push portion 131, the distance between the push member 14 and the side wall of the accommodating cavity 11a decreases, and the elastic member 15 is compressed; when the container cover 1 changes from the open state to the closed state, the button 13 moves upward along the first direction X, and the second push portion 131 no longer applies a force to the push member 14, so the push member 14 can move in the opposite direction along the second direction Y under the action of the restoring force of the elastic member 15, and at this time, the third push portion 141 no longer applies a force to the first push portion 122, and the dust cover 12 can rotate and fall under the action of gravity.

[0086] Furthermore, Figure 4 , Figure 6 and Figure 7As shown, the push member 14 is provided with a limiting protrusion 144, and the side wall of the accommodating chamber 11a is provided with a limiting groove 113e. One end of the elastic member 15 is sleeved on the limiting protrusion 144, and the other end of the elastic member 15 extends into the limiting groove 113e and abuts against the inner wall of the limiting groove 113e, thereby preventing the elastic member 15 from falling off from the push member 14 and improving the working reliability of the container cover 1.

[0087] In a specific embodiment, Figures 4 to 6 As shown, the pusher 14 has an inclined power receiving surface 142, and the second pusher 131 has an inclined power output surface 132. When the button 13 moves along the first direction X, the power output surface 132 can abut against the power receiving surface 142 and push the pusher 14 to slide along the second direction Y.

[0088] In this embodiment, if Figures 4 to 6 As shown, the inclined power output surface 132 and the inclined power receiving surface 142 abut against each other to change the force transmission direction, so that the button 13 moving along the first direction X pushes the pusher 14 to move along the second direction Y. At the same time, transmitting the force through the inclined surface also has the advantage of smooth and reliable force transmission.

[0089] In a specific embodiment, Figure 2 and Figure 3 As shown, the first pushing portion 122 is a plate-shaped structure perpendicular to the second direction Y, and the third pushing portion 141 is a plate-shaped structure perpendicular to the first direction X.

[0090] In this embodiment, the first pushing portion 122 is perpendicular to the second direction Y, and the third pushing portion 141 is perpendicular to the first direction X, so that the force of the third pushing portion 141 moving along the second direction Y can directly and reliably act on the first pushing portion 122, and the force loss is small, thereby improving the reliability of the third pushing portion 141 pushing the dust cover 12 to rotate and lift.

[0091] In a specific embodiment, Figure 8 As shown, the dustproof portion 121 is provided with a rotating shaft 123 at one end close to the first pushing portion 122 , and the rotating shaft 123 is rotatably connected to the cover body 11 .

[0092] In this embodiment, if Figure 8 As shown, a rotation groove 112a is provided on the cover body 11 near the liquid outlet 11b, and the rotation shaft 123 is rotationally connected to the rotation groove 112a, thereby ensuring the smoothness and reliability of the rotational connection between the dustproof part 121 and the cover body 11.

[0093] Specifically, the rotating shaft 123 can be arranged on both sides of the dustproof portion 121 , and the cover body 11 is also correspondingly provided with two rotating grooves 112 a , so that the dustproof cover 12 can rotate relative to the cover body 11 more smoothly.

[0094] More specifically, the cross section of the dust cover 12 is L-shaped, the dustproof portion 121 is a long arm of the L-shape, and the first pushing portion 122 is a short arm of the L-shape.

[0095] In a specific embodiment, Figure 7 As shown, the cover body 11 has guide protrusions 113a arranged at intervals, and guide grooves 113b are formed between the guide protrusions 113a, and the push member 14 can slide in the guide grooves 113b; the guide protrusion 113a includes a limiting portion 113c extending toward the guide groove 113b, and the limiting portion 113c can limit the movement of the push member 14 along the first direction X.

[0096] In this embodiment, if Figure 7 As shown, the guide protrusion 113a can guide the movement of the push member 14, so that the push member 14 moves along a preset route, ensuring that the third push portion 141 accurately abuts against the first push portion 122, and pushes the dust cover 12 to rotate. The limiting portion 113c can limit the movement of the push member 14 along the first direction X, prevent the push member 14 from falling off from the guide groove 113b, and ensure the reliability of the container cover 1.

[0097] In a specific embodiment, Figure 4 and Figure 6 As shown, the pusher 14 is provided with a weight-reducing groove 143, which can reduce the weight of the pusher 14, thereby reducing the force required for the second pusher 131 to push the pusher 14 to move, reducing the resistance felt by the user when pressing the button 13, thereby improving the user experience. At the same time, the weight-reducing groove 143 reduces the raw materials required to produce a pusher 14, so the provision of the weight-reducing groove 143 can also reduce the production cost of the pusher 14.

[0098] In the above embodiments, Fig. 9 As shown, the cover body 11 includes: an upper cover 111, a lower cover 112 and an inner cover 113, the upper cover 111 is connected to the lower cover 112, the inner cover 113 is located between the upper cover 111 and the lower cover 112, and there is a accommodating cavity 11a between the upper cover 111 and the inner cover 113, and the dust cover 12 is rotatably connected to the lower cover 112.

[0099] By arranging the dust cover 12 on the lower cover 112, the dust cover 12 is located outside the accommodating cavity 11a, which facilitates the installation of the dust cover 12. Figure 4 As shown, the upper cover 111 can limit the rotation range of the dust cover 12, preventing the dust cover 12 from moving to a position where it cannot rotate and fall from the lifted state under the action of gravity.

[0100] Specifically, Fig.10 As shown, the inner cover 113 is threadedly connected to the upper cover 111 and the lower cover 112 respectively, and the lower end of the upper cover 111 abuts against the upper end of the lower cover 112.

[0101] Further, such as Figure 7 As shown, the inner cover 113 has a communication hole 113 d connecting the accommodating chamber 11 a and the outside, and the third pushing portion 141 can pass through the communication hole 113 d to contact the dust cover 12 .

[0102] By providing the connecting hole 113d, the pusher 14 can contact the dust cover 12 outside the accommodating chamber 11a, so that the pusher 14 drives the dust cover 12. At the same time, the dust cover 12 does not need to extend into the accommodating chamber 11a, reducing the possibility of liquid entering the accommodating chamber 11a.

[0103] In addition, if Figure 7 As shown, the guide protrusion 113 a , the guide groove 113 b , the limiting portion 113 c and the limiting groove 113 e may all be disposed on the inner cover 113 .

[0104] In a specific embodiment, Figure 2 and Figure 3 As shown, the container body 2 includes an outer shell 21 and an inner liner 22, and the outer shell 21 and the inner liner 22 are connected at the end close to the opening. The connection between the outer shell 21 and the inner liner 22 is a connecting portion 23; the container cover 1 has a mounting groove, and the connecting portion 23 can extend into the mounting groove.

[0105] In this embodiment, if Figure 2 and Figure 3 As shown, the inner liner 22 can improve the heat preservation effect of the container body 2, and the outer shell 21 has good strength and rigidity, which can prevent the inner liner 22 from being damaged by external impact, thereby protecting the inner liner 22. The outer shell 21 is also provided with a convex groove structure, which can cooperate with the convex structure at the lower end of the lower cover 112, thereby realizing a reliable connection between the container cover 1 and the container body 2.

[0106] Furthermore, a mounting groove is formed between the inner cover 113 and the lower cover 112, and a first sealing member 17 is provided in the mounting groove, and the connecting portion 23 extends into the mounting groove and abuts against the first sealing member 17, thereby preventing the liquid in the container body 2 from flowing out from between the container cover 1 and the container body 2. A second sealing member 18 is also provided at the lower end of the inner cover 113, and the second sealing member 18 abuts against the inner liner 22, thereby further preventing the liquid in the container body 2 from flowing out from between the container cover 1 and the container body 2.

[0107] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
