Description

Technical Field

DETAILED DESCRIPTION

[0032] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purpose, the specific implementation methods, components, features and effects of the present application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, components, or characteristics in one or more embodiments may be combined in any suitable form.

[0033] The present invention provides a container cover, which can be used in conjunction with other components so that it can be specifically manifested as different products (such as food containers, etc.), and the food container is sealed by a deformable sealing ring. The sealing performance of the food container is improved and the sealing operation is simplified by improving the structure of the container cover, thereby improving the user experience.

[0034] Specifically, combined Figures 1 to 7 As shown, the container cover of the present invention comprises a lower cover 200, an upper cover 100 connected to the lower cover 200, a switch member 300, two movable components 400 relatively arranged on the lower cover 200, and a deformable sealing ring 500; the switch member 300 is movably installed in the upper cover 100; a spacing adjustment mechanism for adjusting the relative spacing between the two movable components 400 through the switch member 300 is arranged between the two movable components 400 and the switch member 300, and the switch member 300 can switch and slide between a non-locking position and a locking position relative to the two movable components 400 through the spacing adjustment mechanism; the sealing ring 500 is sleeved on the outer sides of the two movable components 400; in the locking position, the relative spacing between the two movable components 400 is increased to cause the sealing ring 500 to expand and deform, and the container cover is in a sealed state.

[0035] The switch member of the present invention can be movably switched and slid between the non-locking position and the locking position in the upper cover, and the relative distance between the two movable components is adjusted by the spacing adjustment mechanism, so that the relative distance between the two movable components changes, and the sealing ring sleeved outside the two movable components is deformed. When the switch member is switched to the locking position, the spacing adjustment mechanism adjusts the relative distance between the two movable components to increase, so that the two movable components can expand outward, so that the sealing ring sleeved on the outer sides of the two movable components is deformed, thereby abutting against the inner wall of the container body of the food container, thereby achieving the effect of sealing the food container; and when the switch member is switched to the non-locking position, the spacing adjustment mechanism adjusts the relative distance between the two movable components to decrease, so that the two movable components can retract inward, so that the deformed sealing ring is reset when the action force of the two movable components is lost, thereby separating from the inner wall of the container body of the food container, thereby achieving the effect of releasing the seal of the food container; the present invention enables the container cover to be in a sealed state or a non-sealed state in the above manner, improves the sealing performance of the container cover, and the operation is cumbersome and simple.

[0036] In one embodiment, in combination Figure 4 and Figure 5 As shown, the switch member 300 includes an operating portion 310 and a touch portion 320 connected below the operating portion 310, and a sliding side edge 330 is provided at the connection between the touch portion 320 and the operating portion 310; the upper cover 100 is provided with a switch hole 110, and two opposite sides of the switch hole 110 are respectively provided with slide rails 111, the touch portion 320 is arranged through the switch hole 110, and the sliding side edge 330 is slidably connected with the slide rail 111. The present invention sets the sliding side edge and the slide rail to limit the sliding of the switch member, prevents the switch member from shifting during the switching sliding process between the non-locking position and the locking position, and causes the container cover to be unable to be used normally, ensures that the switching sliding operation of the switch member can be effectively performed, avoids the occurrence of use failures, and improves the user experience.

[0037] Furthermore, a stop protrusion 111a is provided at one end of the slide rail 111, and a stop groove 330a is correspondingly provided on the sliding side 330; when the switch member 300 slides to the locking position in the switch hole 110, the stop protrusion 111a is limited in the stop groove 330a. The present invention uses the stop protrusion and the stop groove in cooperation to restrict the movement of the switch member when it is in the locking position. Under the premise that the switch member is not subjected to external force, the switch member will always remain in the locking position, ensuring that the container cover has a high sealing performance and will not be easily switched from the locking position to the non-locking position due to other factors.

[0038] In one embodiment, the orthographic projection of the switch hole 110 is located between the two movable components 400, the two slide rails 111 are respectively located above the two movable components 400, and the first distance from a single movable component to the closest slide rail is the same as the second distance from another movable component to the other slide rail. The present invention limits the position of the switch hole so that its orthographic projection is located between the two movable components, and the distances from the movable components on both sides of the switch hole to the slide rails are the same, so that when the switch member can slide and switch between the non-locking position and the locking position in the switch hole, the distance between the two movable components can be increased or reduced in a consistent manner, thereby effectively ensuring that the deformation of the sealing ring in each direction will not deviate too much, further improving the sealing performance.

[0039] In one embodiment, in combination Figures 1 to 7 As shown, the spacing adjustment mechanism includes two first sliding connection blocks 400a and two first sliding grooves 300a respectively connected to the two first sliding connection blocks 400a in a sliding manner; one of the two first sliding grooves 300a and the two first sliding connection blocks 400a is respectively arranged on the two movable components 400, and the other one is correspondingly arranged on the switch member 300; the spacing between the first ends of the two first sliding connection blocks 400a is greater than the spacing between the second ends of the two first sliding connection blocks 400a; in the locked position, the second end of the first sliding connection block 400a is located in the first sliding groove 300a, or the first sliding groove 300a is located at the first end of the first sliding connection block 400a.

[0040] Specifically, the two first sliding connection blocks of the present invention are slidably connected to the two first sliding grooves, and the spacing between the first ends of the two first sliding connection blocks is greater than the spacing between the second ends of the two first sliding connection blocks (i.e., the two first sliding connection blocks are distributed in an eight-shaped shape, the second end of the first sliding connection block is a narrow end, and the first end is a wide end), and the spacing between the first ends of the two first sliding grooves is greater than the spacing between the second ends of the two first sliding grooves (i.e., the two first sliding grooves are distributed in an eight-shaped shape, and the eight-shaped distribution corresponds to the eight-shaped distribution of the first sliding connection block, the second end of the first sliding groove is a narrow end, and the first end is a wide end). When the switch slides, the two first sliding connection blocks and the two first sliding grooves will work together using the inclined surfaces that abut each other, thereby realizing the change in the spacing between the two movable components.

[0041] The container cover of the present invention can have two embodiments for the positions of the two first sliding connection blocks and the two first sliding grooves. One embodiment is that the two first sliding connection blocks are located on the upper side surfaces of the two movable components, and the two first sliding grooves are located on the lower side surface of the switch member. Figures 5 to 7 As shown, when the switch member is in the locked position, the second end (narrow end) of the first sliding connection block is located in the first sliding groove, and the first end (wide end) is located outside the first sliding groove. At this time, the two movable components expand outward and open the sealing ring, so that the sealing ring abuts against the inner wall of the container body of the food container, thereby achieving a sealing function; and when the switch member is in the unlocked position, the first end (wide end) of the first sliding connection block is located in the first sliding groove, and the second end (narrow end) is located outside the first sliding groove. At this time, the two movable components retract inward and do not open the sealing ring, so that the sealing ring does not abut against the inner wall of the container body, thereby achieving release of the seal;

[0042] Secondly, the two first sliding connection blocks are located on the lower side of the switch member, and the two first sliding grooves are located on the upper side of the two movable components. When the switch member is in the locked position, the first sliding groove is located at the first end (wide end) of the first sliding connection block. At this time, the two movable components expand outward and open the sealing ring, so that the sealing ring is against the inner wall of the container body of the food container to achieve a sealing function; the core idea of ​​the two implementation methods is that when the switch member switches between the locked position and the unlocked position, the sliding of the switch member can change the distance between the two movable components slidably connected thereto, so that the distance between the two movable components changes, so that the sealing ring is deformed, thereby achieving a sealing or non-sealing function.

[0043] In one embodiment, in combination Figures 1 to 7 As shown, the two movable components 400 each include a slider 410 and a plurality of adjustment blocks 420. The slider 410 has a slider body 411. One side of the slider body 411 is an opposite side 411a. The two sides connected to the opposite sides 411a are guide sides 411b. The distance between the connecting ends of the two guide sides 411b and the opposite sides 411a is greater than the distance between the other ends of the two guide sides 411b (that is, the two guide sides are inclined relative to the opposite sides 411a). The opposite sides 411a of the two slider bodies 411 are arranged opposite to each other, and each of the opposite sides 411a is provided with a first sliding connection block 400a or a first sliding groove 300a. The plurality of adjustment blocks 420 are respectively movably matched with the slider 410. In order to facilitate understanding of the present technical solution, Figure 3 and Figure 4 Some components are omitted (such as sliders)

[0044] The present invention combines the slider and several adjustment blocks into the movable assembly, wherein the relative sides of the two slider bodies are arranged opposite to each other, and each relative side is respectively provided with a first sliding connection block or a first sliding groove, ensuring that the slider body can cooperate with the first sliding groove or the first sliding connection block of the switch member, so that the switch member can adjust the spacing between the two slider bodies when sliding between the locking position and the unlocking position; the slider body is also provided with a guide side, and the guide side is flexibly matched with the adjustment block, so that the adjustment block can perform corresponding expansion or retraction actions with the movement of the slider, so that the container cover has sealing and non-sealing functions. In addition, the present invention utilizes the movable cooperation of the slider and several adjustment blocks, so that the sealing ring can obtain support forces in multiple directions and undergo elastic deformation, thereby improving the sealing performance of the container cover.

[0045] Furthermore, each of the adjusting blocks 420 has a limiting groove 421 on its outer side, and the sealing ring 500 is disposed in the limiting groove 421. The present invention provides limiting grooves on the outer side of each adjusting block to accommodate the sealing ring and operate the sealing ring by means of the limiting grooves.

[0046] Furthermore, the adjustment block 420 has an oblique side 420a that is movably matched with the guide side 411b, and a sliding guide structure for allowing the adjustment block 420 to follow the movement of the slider 410 is provided between the oblique side 420a and the guide side 411b. The present invention uses the sliding guide structure to enable the adjustment block to follow the movement of the slider and perform corresponding expansion or retraction actions, so that the container cover has sealing and non-sealing functions. The sliding guide structure includes a second sliding connection block 422 and a second sliding groove 412 that is slidably connected to the second sliding connection block 422; one of the second sliding connection block 422 and the second sliding groove 412 is arranged on the oblique side 420a, and the other one is correspondingly arranged on the guide side 411b.

[0047] The container cover of the present invention can have two embodiments for the positions of the two second sliding connection blocks and the two second sliding grooves. One is that the second sliding connection block is located on the oblique side of the adjustment block, and the second sliding groove is located on the guide side of the slider. Figures 5 to 7 As shown, when the switch member is in the locked position, the switch member drives the two sliders to move in opposite directions, and the slider drives the adjusting block movably matched with the slider to expand, thereby expanding the sealing ring so that the sealing ring undergoes elastic deformation and makes the sealing ring abut against the inner wall of the container body of the food container;

[0048] Secondly, the second sliding connection block is located on the guide side of the slider, and the second sliding groove is located on the oblique side of the adjustment block; the core idea of ​​the two implementation modes is that when the switch member switches between the locked position and the unlocked position, the sliding of the switch member can change the distance between the sliders matched with it, so that the distance between the two sliders changes, and the adjustment block performs corresponding expansion or retraction action, thereby realizing the sealing or non-sealing function.

[0049] Furthermore, the second sliding connection block 422 is arranged obliquely, and the second sliding groove 412 is arranged obliquely corresponding to the second sliding connection block 422. In the present invention, the second sliding connection block 422 and the second sliding groove 412 are arranged obliquely, so that when the slider moves in opposite directions under the action of the switch, the slider can push the adjustment block to expand, thereby realizing the sealing function of the container cover, and when the slider moves in opposite directions under the action of the switch, the slider can pull the adjustment block to retract, thereby realizing the non-sealing function of the container cover.

[0050] In one embodiment, the adjustment block 420 is provided with a clearance groove 423; the upper side of the lower cover 200 or the lower side of the upper cover 100 is provided with a plurality of fixing columns 210, the upper cover 100 and the lower cover 200 are fixedly connected through the fixing columns 210, and each fixing column 210 passes through one of the clearance grooves 423. The present invention provides a clearance groove to play a positioning and guiding role for the adjustment block during the sliding process.

[0051] Furthermore, the upper side surface of the lower cover 200 or the lower side surface of the upper cover 100 is provided with fixing grooves 130 corresponding to the plurality of fixing columns, and the connection between the upper cover and the lower cover is achieved through the connection and cooperation between the fixing grooves 130 and the fixing columns 210 .

[0052] In one embodiment, in combination Figure 3 As shown, the lower side surface of the upper cover 100 is provided with a first limiting rib 120, and the upper side surface of the lower cover 200 is provided with a second limiting rib 220. When the switch member is located in a non-sealed position, the first limiting rib and the second limiting rib are both against the adjustment block. The present invention enables the adjustment block to slide on the same plane through the cooperation between the upper cover and the lower cover, and the first limiting rib and the second limiting rib are provided to limit the retraction action of the adjustment block to prevent the adjustment block from having inconsistent reset distances and affecting the subsequent sealing effect.

[0053] The present invention further provides a food container, comprising a container body 600 for holding food, wherein the container mouth of the container body 600 is provided with the container cover as described above, and when the container cover is in a sealed state, the sealing ring 500 is sealedly connected to the inner wall of the container body 600. The food container disclosed in the present invention adjusts the relative distance between the two movable components by switching and sliding the switch member between the non-locking position and the locking position, so that the relative distance between the two movable components changes, and the sealing ring sleeved outside the two movable components is deformed, so that the food container is in a sealed state or a non-sealed state, thereby improving the sealing performance of the food container, and the operation is simple and cumbersome.

[0054] In one usage scenario, the user assembles the container cover to the container mouth on the container body, and the user slides the switch member to a locked position by sliding the switch member, wherein the two first slide grooves on the lower side of the switch member cooperate with the two first sliding connecting blocks on the two sliders to drive the two sliders to move away from each other, and at the same time, the two second slide grooves on the slider cooperate with the second sliding connecting blocks on the adjustment block, so that the multiple adjustment blocks expand and expand and deform the sealing ring located on the limit groove thereof, so that the sealing ring abuts against the inner wall of the container body to achieve a sealing function.

[0055] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
