It can be understood that when the cover body 2 is lifted and opened by the lifting part 7, the anti-theft structure 52 is damaged and can not be restored, thereby playing an anti-theft role and effectively preventing the food from being opened by others during the transportation process. Of course, the anti-theft structure 52 may be any other shape.
In this embodiment, the container body 1 and the cover are rectangular, and in some embodiments, may be round, square, or any other shape. The container may be made of food grade plastic or other materials and may be used as a take-away container, a microwave oven container, and daily tableware.
As shown in fig. 11-13, which is a schematic structural diagram of a second embodiment of the container of the present invention, the difference from the first embodiment is that a convex portion 212 for enlarging the accommodating space of the lid body 2 is provided on the lid body 2, the convex portion 212 is formed by upwardly protruding one side of the top portion 21 of the lid body 2 close to the covering portion 22, two sides of the convex portion 212 are respectively disposed obliquely to the direction of the top portion 21 and the covering portion 22, wherein the cross section of the fixing portion 32 matches the cross section of the convex portion 212, the fixing protrusion 322 is provided on the fixing portion 32, and the fixing hole 321 is provided on the convex portion 212; alternatively, the fixing hole 321 is provided on the fixing portion 32, and the fixing protrusion 322 is provided on the convex portion 212.
It will be appreciated that the fixing portion 32 overlies the upper portion of the protrusion 212, the covering portion 31 overlies the top portion 21 of the cover 2, and the protrusion 212 and the top portion 21 have a height difference, so that when the air pressure in the container/case 1 increases and pushes the covering portion 31 open, the covering portion 31 can rotate around its connection with the fixing portion 32, and when the covering portion 31 rotates, the covering portion can rotate to the position of the protrusion 212 to the maximum extent, the protrusion 212 effectively blocks the covering portion 31 from turning over to the side of the protrusion 212, ensuring that when the air pressure in the container/case 1 is balanced, the covering portion 31 can automatically return to the position covering the top portion 21 and closing the air outlet 211.
The convex portion 212 and the covering portion 22 are connected by a connecting base, and the connecting base is provided with a plurality of reinforcing ribs 8, and the plurality of reinforcing ribs 8 are provided at intervals in the circumferential direction of the connecting base. It will be appreciated that the ribs 8 serve to reinforce the lid 2 so that the lid 2 is not easily deformed or deformed; at the same time, when a plurality of lid bodies 2 are placed one on top of the other, the reinforcing ribs 8 prevent the stacked lid bodies from being pressed together, so that they can be easily separated.
When the container of the first or second embodiment is used, food is placed in the case 1 and hermetically sealed by the lid 2, and the flexible connecting portion 4 is folded by rotation so that the fixing protrusions 322 are inserted into and fixed to the fixing holes 321; when the container is heated in a microwave oven, due to the temperature rise in the container/box 1, the instantly expanding hot/water vapor (pressure increase) pushes the protrusion 311 away, so that the cover 31 leaves the top 21 and the vapor is exhausted through the exhaust port 211; when the air pressure inside and outside the container/box body 1 approaches, the covering part 31 automatically resets and seals the air outlet 211 through the protrusion 311, so that the container forms a closed space, and harmful substances such as dust and the like are effectively prevented from falling into the container; when the boiling food is directly put into the container, the boiling food is discharged in the same way.
When the temperature in the container drops, causing the air in the container to shrink (the air pressure is reduced), the top 21 of the cover body 2 sinks, and the covering part 31 is kept flat by the reinforcing ribs 312 on the covering part, so that the second concave part 232 is not consistent with the plane of the covering part 31, an air inlet space is formed between the protrusion 311 and the air outlet 211, and the external air enters the container from the air outlet 211; when the air pressure inside and outside the container/box body 1 approaches, the covering part 31 automatically resets, the concave part 23 receives the exhaust cover 3 and the protrusion 311 on the covering part 31 closes the exhaust port 211; so that the protrusions 311 keep closing the exhaust ports 211 after the completion of the intake or exhaust.
Because the inosculating structure 6 and the compact structure 9 are arranged between the covering part 22 and the buckling part 13, and the covering part 22 is arranged flush with the end part of the buckling part 13, once the box body 1 is sealed by the cover body 2, the box body is difficult to open, a user can pull the lifting part 7 to destroy the anti-theft structure 52, and pull the lifting part 7 as a handle to pull the cover body 2 open; it will be appreciated that the tamper-evident structure 52 is not reversible once broken, effectively preventing the container from being opened by others during transport.
In the invention, when the air pressure in the container is higher/lower than the external air pressure, the air outlet 211 is opened, the balance of the internal air pressure and the external air pressure is maintained through air inlet/exhaust, and the air outlet 211 keeps a closed state after the air pressure is balanced, thereby realizing automatic adjustment according to different pressures in the container/box body 1 and effectively avoiding the introduction of harmful substances such as dust and the like.
It is to be understood that the foregoing examples, while indicating the preferred embodiments of the invention, are given by way of illustration and description, and are not to be construed as limiting the scope of the invention; it should be noted that, for those skilled in the art, the above technical features can be freely combined, and several changes and modifications can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention; therefore, all equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the claims of the present invention.
