Description

Technical Field

[0001] This utility model relates to the field of food storage containers, and in particular, to a single-ear lid for food storage containers. Background Technology

[0002] Food storage containers are not only convenient and practical, but they also allow for the organized storage of food. As people's living standards continue to improve, the variety of food storage containers is increasing. When storing food in food storage containers, they need to be sealed to ensure freshness. In this sealed state, the lower air pressure inside the container creates a pressure difference with the outside air. Opening the container requires overcoming this pressure difference, making the lid difficult to open and inconvenient for daily use. Therefore, providing a food storage container that is easy to open is crucial. This necessitates a single-ear lid for easy-to-open food storage containers. Utility Model Content

[0003] The purpose of this invention is to provide a simple and practical single-ear lid for food storage containers that allows for one-handed opening and venting.

[0004] The above-mentioned objective of this utility model is achieved through the following technical solution: A single-ear lid for food storage containers, the lid comprising a body portion and an edge portion located on the outer periphery of the body portion, the edge portion being higher than the body portion, and the top of the lid having a shape that is high on the outside and low on the inside. The main body has a groove at one end, and the edge has an opening that communicates with the top of the groove. The opening and the top surface of the outer end of the groove form a support surface. An exhaust valve is provided in the groove. The exhaust valve includes a pressing end facing inward and an extending end facing outward. The bottom wall of the extending end overlaps with the support surface. The middle part of the side wall of the exhaust valve is rotatably connected to the groove through a rotating shaft. A sealing post is provided at the bottom of the protruding end near the rotating shaft, and a vent hole is provided in the groove at the position opposite to the sealing post; when the protruding end contacts the support surface, the sealing post blocks the vent hole; when the pressing end flips along the rotating shaft to the bottom of the groove, the sealing post separates from the vent hole.

[0005] Furthermore, a positioning block is provided on the side wall of the groove away from the opening. The positioning block is in the shape of an inverted triangle, and its top is an arc-shaped buffer part facing the pressing end. The end of the pressing end is provided with a buffer surface that cooperates with the arc-shaped buffer part. When the pressing end slides past the arc-shaped buffer part to the bottom of the groove, the sealing column disengages from the vent hole.

[0006] Furthermore, the two opposite side walls of the groove extend inward to form the rotating shaft, and the bottom of the exhaust valve side wall extends downward to form a hinge block. The hinge block is provided with a slot that rotatably connects with the rotating shaft.

[0007] Furthermore, a sealing sleeve is movably connected inside the vent hole, and the opening of the sealing sleeve facing the sealing column is set in a trumpet shape, and the end of the sealing column is provided with a tapered part that cooperates with it.

[0008] Furthermore, the sealing sleeve has an I-shaped cross-section, the outer wall of the sealing sleeve is provided with an annular groove that matches the edge of the vent hole, the sealing sleeve has a through hole in the axial middle, and the end of the through hole facing the groove is flared.

[0009] Furthermore, the bottom wall at the connection between the edge portion and the main body portion is provided with an installation groove, and a sealing strip is embedded and fixed in the installation groove, and the sealing strip is pressed and abutted against the inner wall of the food storage box.

[0010] Furthermore, a protrusion is provided on the outer periphery of the bottom edge portion, and the bottom wall of the protrusion abuts against the top edge of the outer edge of the food storage box.

[0011] Compared with the prior art, the beneficial technical effects of this utility model are as follows: 1. By optimizing the structure of the lid and the vent valve, and setting the groove and edge opening, the overall structure of the lid is maintained. The support surface at the opening can support and position the vent valve. This structure is simple, simplifies the lid molding mold, and reduces investment costs. 2. The overall structure of the exhaust valve is simple. The bottom of the side wall of the exhaust valve extends downward to form a hinge block. The hinge block has a slot that is rotatably connected to the rotating shaft. The bottom wall of the extended end of the exhaust valve overlaps the support surface. The valve will not fall off due to accidental contact. The cover and the body abut against each other. When the exhaust valve rotates to the support surface, the sealing column seals the vent hole. 3. The sealing column of this utility model is located on the side close to the rotating shaft. When the sealing column is pulled out, it can be rotated with the rotating shaft to form a lever effect, which makes the force required to pull out the sealing column less and makes it easier to pull out the sealing column.

[0019] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] Reference Figures 1 to 6 This utility model discloses a single-ear lid for a food storage container. The lid includes a main body 1 and an edge portion 2 located on the outer periphery of the main body 1. The edge portion 2 is higher than the main body 1, and the top of the lid has a shape that is high on the outside and low on the inside. A mounting groove 8 is provided on the bottom wall at the connection between the edge portion 2 and the main body 1. A sealing strip 9 is embedded and fixed in the mounting groove 8, and the sealing strip 9 is pressed and abutted against the inner wall of the food storage container.

[0021] The bottom shape of the edge section 3 can be adapted to the top edge shape of different food storage containers. For example... Figure 6 Furthermore, a protrusion 33 can be provided on the outer periphery of the bottom of the edge portion 3. The bottom of the edge portion 2 fits against the inner edge of the food storage container, and the bottom of the protrusion 33 fits against the outer edge of the food storage container, making the overall integrity of the lid and the container body better and more aesthetically pleasing. At the same time, the protrusion 33 makes the edge portion 3 of the lid thicker and stronger, reducing the possibility of deformation due to thermal expansion and contraction during use.

[0022] The main body 1 has a groove 3 at one end, and an opening 21 through the top of the groove 3 is provided on the edge 2. The opening 21 and the top surface of the outer end of the groove 3 form a support surface 31. An exhaust valve 4 is provided in the groove 3. The exhaust valve 4 includes a pressing end 41 facing inward and an extending end 42 facing outward. The bottom wall of the extending end 42 overlaps with the support surface 31. The middle part of the side wall of the exhaust valve 4 is rotatably connected to the groove 3 through a pivot 32. The cross-sectional shape of the extending end 42 and the cross-sectional shape of the outer edge 3 can be kept consistent.

[0023] Preferably, the two opposite side walls of the groove 3 extend inward to form a rotating shaft 32, and the bottom of the side wall of the exhaust valve 4 extends downward to form a hinge block 45. The hinge block 45 is provided with a slot 46 that rotatably connects with the rotating shaft 32. By optimizing the structure of the lid and the exhaust valve 4, the groove 3 and the opening 21 of the edge part 2 are set to maintain the overall structure of the lid. The support surface 31 at the opening 21 can support and position the exhaust valve 4. This structure is simple, simplifies the lid forming mold, and reduces investment costs. A sealing post 43 is provided at the bottom of the protruding end 42 near the rotating shaft 32, and a vent hole 5 is provided in the groove 3 at the position opposite to the sealing post 43; when the protruding end 42 contacts the support surface 31, the sealing post 43 blocks the vent hole 5; when the pressing end 41 is flipped along the rotating shaft 32 to the bottom of the groove 3, the sealing post 43 separates from the vent hole 5.

[0024] A positioning block 6 is provided on the side wall of the groove 3 away from the opening 21. The positioning block 6 is in the shape of an inverted triangle, and the top of it faces the pressing end 41 with an arc-shaped buffer part 61. The end of the pressing end 41 is provided with a buffer surface 44 that cooperates with the arc-shaped buffer part 61. When the pressing end 41 slides past the arc-shaped buffer part 61 to the bottom of the groove 3, the sealing post 43 disengages from the vent hole 5.

[0025] A sealing sleeve 7 is movably connected inside the vent 5. The sealing sleeve 7 has an I-shaped cross-section, and its outer wall has an annular groove 71 that mates with the vent 5. A through hole 72 is located in the axial center of the sealing sleeve 7, with the end of the through hole 72 facing the groove 3 being flared. A tapered portion 47 mates with the end of the sealing column 43. The tapered portion 47 allows for easier insertion of the sealing column 43 into the sealing sleeve 7 due to its tapered shape. Furthermore, positioning the sealing column 43 close to the rotating shaft 32 allows for lever-like action between the rotating shaft 32 and the sealing column 43 when it is turned, reducing the force required to open the food storage container.

[0026] The implementation principle of this embodiment is as follows: (Refer to...) Figure 5When using the container, first place the lid on the upper surface of the container body, then press down the protruding part so that the bottom of the exhaust valve 4 is in contact with the support surface 31. At this time, the end face of the pressing end 41 should be located at the top of the positioning block 6, and the sealing post 43 is sealed in the sealing sleeve 7. When it is necessary to open the lid, press the pressing end 41 of the exhaust valve 4 firmly, so that it slides past the positioning block 6 to the bottom of the groove 3, making a clicking sound. This exposes one end of the vent 5 to the outside air, thus connecting the air inside the container with the outside air, thereby reducing the air pressure difference between the inside and outside of the container. This reduces the resistance to the sealing post 43, making it easier to pull out the sealing post. At the same time, using the lever principle, the pivot 32 is set as the fulcrum. At this time, one-handed operation applies an upward force to the edge of the lid 2 or the protruding end 42 of the exhaust valve 4, thereby assisting in the easy separation of the container body and the lid.

[0027] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
