Description

Technical Field

[0001] The utility model belongs to the technical field of port sealing, and in particular relates to a sealing cover and a container. Background Art

[0002] Currently, people often use sealed containers to store food in their daily lives to extend its shelf life. In existing sealed containers, the container's opening is typically sealed with a sealing lid equipped with a sealing ring. The tight fit between the sealing ring and the container achieves a seal. However, if the container's opening is large, the force on the sealing ring increases, and the outward expansion force of the sealing ring also increases. The force of the sealing ring on the inner wall of the container can easily cause the container's opening to deform, resulting in a gap between the sealing ring and the container's opening, and thus poor sealing. To address this problem, the container's opening wall needs to be thickened to resist the squeezing force of the sealing ring, but this increases cost and manufacturing difficulty.

It should be noted that the embodiments and features in the embodiments of this application can be combined with each other unless there is a conflict. The same reference numerals used throughout the drawings indicate the same or similar parts.

[0041] It should be noted that, unless otherwise specified, when a feature is referred to as being "fixed" or "connected" to another feature, it may be directly fixed or connected to the other feature or indirectly fixed or connected to the other feature. In addition, the terms "upper," "lower," "left," and "right" used in this utility model are only used with respect to the relative positions of the components of the utility model in the accompanying drawings.

[0042] Reference Figures 1 to 8 A sealing cover comprises a cover body 1, a reset mechanism, a pressing component 2, a sealing mechanism 3 and a locking mechanism. The sealing mechanism 3 comprises a base plate 31 and a sealing ring 32, and the pressing component 2 and the base plate 31 are respectively located on the upper and lower sides of the cover body 1. The reset mechanism is located between the base plate 31 and the cover body 1; the pressing component 2 passes through the cover body 1 and is connected to the base plate 31; the pressing component 2 is movably connected to the locking mechanism. The pressing component 2 drives the base plate 31 and the sealing ring 32 closer to the cover body 1, and at the same time drives the locking mechanism to engage with the cover body 1; or the pressing component 2 drives the base plate 31 and the sealing ring 32 away from the cover body 1, and the reset mechanism resets and drives the locking mechanism to disengage from the connection with the cover body 1. A first groove 13 with a downward-facing notch is formed on one side of the lid 1, near the base plate 31. The annular sealing ring 32 is connected to the base plate 31 on its inner side, and extends into the first groove 13 on its outer side, vertically positioned above the inner side. In this embodiment, the first groove 13 is designed on the container's sealing lid. When the lid is closed and sealed, the container opening, or the opening to be sealed, fits into the first groove 13. The sealing ring 32 is squeezed and squeezed into the first groove 13, blocking the outer side of the opening to prevent deformation.

[0043] Specifically, a plurality of ribs 4 are spaced apart within the first slot 13. The ribs 4 serve as reinforcing ribs. The two opposing side walls within the first slot 13 are, from the inside to the outside, a first side wall 111 and a second side wall 121. The ends of each rib 4 are fixedly connected to the first side wall 111 and the second side wall 121, respectively. The upper end of the sealing ring 32 is located below each rib 4. The reinforcing ribs within the first slot 13 of this embodiment enhance the structural stability of the first slot 13 by resisting the force applied during sealing. The ribs also better block the outside of the can opening to prevent deformation.

[0044] Specifically, the first sidewall 111 is provided with a first guide portion 1111 near the notch. The first guide portion 1111 is inclined and gradually approaches the bottom plate 31 from top to bottom. The second sidewall 121 is provided with a second guide portion 1211 near the notch. The second guide portion 1211 is inclined and gradually moves away from the bottom plate 31 from top to bottom. The provision of the first guide portion 1111 facilitates the sealing ring 32 to extend into the first slot 13, thereby increasing its outer diameter and providing a tighter connection with the inner wall of the tank mouth, thereby improving the sealing performance of the sealing ring 32.

[0045] Specifically, the bottom end of the second guide portion 1211 is located above the bottom end of the first guide portion 1111 in the vertical direction and together form the notch. The provision of the second guide portion 1211 facilitates the can mouth to extend into the first slot 13 .

[0046] Specifically, a second clamping groove 311 with a notch facing outward is formed on the outer circumference of the bottom plate 31 , and the inner side of the sealing ring 32 can be inserted into the second clamping groove 311 .

[0047] Specifically, the sealing ring 32 comprises a first body 321 and a second body 322 fixedly connected in sequence from top to bottom. Both the first body 321 and the second body 322 are annular. The upper end of the second body 322 extends into the first slot 13, and the lower end is tightly connected to the outer periphery of the first body 321. The inner periphery of the first body 321 is inserted into the second slot 311. The first body 321 is arranged horizontally and forms an angle α with the second body 322, where 90° < α < 180°. Due to the angle between the first body 321 and the second body 322, when the sealing ring 32 moves upward as a whole, the outer diameter can be increased without significantly deforming to achieve a sealing effect.

[0048] A container includes the sealing cover as described above and a container body 5, wherein the sealing mechanism 3 is arranged at the open end 51 of the container body 5, the first card groove 13 can be used for the open end 51 of the container body 5 to be inserted, and the sealing ring 32 abuts against the inner wall of the container body 5 when it is close to the cover body 1.

[0049] Specifically, the open end 51 of the container body 5 is provided with an annular boss 52 on its end surface, and a stepped surface 53 is provided on its outer side, located near the open end 51 and below the boss 52. An annular first side panel 11 and a second side panel 12 are fixed to the lid body 1 on the side near the base plate 31. The second side panel 12 is spaced apart and sleeved outside the first side panel 11. The gap between the second side panel 12 and the first side panel 11 forms the first retaining groove 13. The ends of each rib 4 are fixedly connected to the first side panel 11 and the second side panel 12, respectively. When the boss 52 is inserted into the first retaining groove 13, the end of the second side panel 12 abuts the stepped surface 53, and the outer side of the boss 52 contacts the first side panel 11. The provision of the annular boss 52 and the stepped surface 53 prevents the can mouth from extending too far into the first retaining groove 13, thus preventing the end of the can mouth from contacting the rib 4 and causing damage to the can mouth. Among them, the side surface of the first side plate 11 close to the second side plate 12 forms a first side wall 111, the side surface of the second side plate 12 close to the first side plate forms a second side wall 121, the first guide portion 1111 is located on the first side plate 11, and the second guide portion 1211 is located on the second side plate.

[0050] Specifically, a limiting plate 54 is provided around the outer side of the container body 5 , and the limiting plate 54 is located below the boss 52 and forms the step surface 53 on a side close to the boss 52 , that is, the upper end surface of the limiting plate 54 forms the step surface 53 .

[0051] Other details of the sealing cover and container described in the present invention can be found in the prior art and will not be described in detail here.

[0052] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
