When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be an intermediate component.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] In this application, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly indicate the number or order of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0040] See Figures 1 to 9 The present application provides a sealed container 1000, comprising a box body 100, a box lid 200, and a sealing ring 300. The box body 100 has a bottom wall 110 and side walls 120 extending upward from the edge of the bottom wall. The bottom wall 110 and the side walls 120 form a receiving cavity 130, which can be used to store food, etc. For ease of description, the bottom wall 110 extends generally in a horizontal direction, and the direction perpendicular to the bottom wall 110 is a vertical direction.

[0041] The box cover 200 is combined with the box body 100 to close the accommodating cavity 130. The box cover 200 includes a body 210 extending approximately in the horizontal direction. The bottom of the body 210 is provided with an annular groove 221 opening toward the bottom wall 110. Accordingly, the annular groove 221 extends in the vertical direction.

[0042] The sealing ring 300 includes a connecting portion 310 embedded in the annular groove 221 and a first lip 320 located outside the annular groove 221 and extending toward the side wall 120. When the box cover 200 and the box body 100 are combined, the first lip 320 is deformed by the side wall 120 and seals the accommodating cavity 130.

[0043] In the sealed container of the present application, the extension direction of the annular groove 221 makes the overall demoulding direction of the box cover 200 vertical. Compared with the existing technology, the size of the corresponding mold is reduced, the requirements for the injection molding equipment are reduced, and thus the manufacturing cost is reduced.

[0044] The bottom of the body 210 is provided with an inner plug portion 220 that extends into the box body 100, and an annular groove 221 is provided in the inner plug portion 220. In the figure, the first lip portion 320 includes a connecting section 321 and a deformable section 322, and the connecting section 321 is connected to the connecting portion 310. The deformable section 322 is connected to the connecting section 321, and when the box cover 200 and the box body 100 are combined, the deformable section 322 is deformed upward by the action of the side wall 120. The inner plug portion 220 and the side wall 120 are spaced apart, that is, there is a gap 121 as shown in the figure between them. When the deformable section 322 deforms upward, at least a portion is located in the gap 121. Further preferably, the inner plug portion 220 and the side wall 120 clamp the deformable section 322 that extends into the gap 121 to improve the sealing performance.

[0045] Combined with the attachment again Figure 9 The deformation section 322 has a fixed end 3221 connected to the connecting section 321 and an opposite free end 3222. The deformation section 322 gradually becomes thinner from the fixed end 3221 to the free end 3222, which is conducive to its own deformation and reset. Among them, the sealing ring 300 is made of materials such as silicone.

[0046] In one embodiment, the annular groove 221 has an outer portion 2211 and an inner portion 2212. When the lid 200 and the box body 100 are combined, the first lip 320 deforms and abuts against the end of the outer portion 2211, which is considered the second seal b. The abutment between the first lip 320 and the sidewall 120 is considered the first seal a. In the height direction, the outer portion 2211 is lower than the inner portion 2212. The inner plug 220 has a surface 222 located on the inner portion 2212 and close to the bottom wall 110. The sealing ring 300 is flush with the surface 222, preventing excessive oil or stains from remaining due to unevenness.

[0047] Furthermore, the annular groove 221 has a first groove wall 2213 located on the outside and a second groove wall 2214 located on the inside. A protruding ring 311 is provided on the outside of the connecting portion 310. The protruding ring 311 abuts against the first groove wall 2213 to serve as a third seal C. There are multiple protruding rings 311 arranged at intervals along the height direction.

[0048] In another embodiment, the inner side of the connecting portion 310 abuts against the second groove wall 2214 to serve as a new seal. If combined with the above embodiment, it is regarded as the fourth seal d.

[0049] See also Figure 2 and Figure 8In one embodiment, the lid 200 is provided with a vertically extending recess 230, with a through hole 231 disposed therein. The sealed container 1000 further includes a latch 400 slidably mounted in the recess 230. The latch 400 includes a blocking portion 410. During the sliding process, the latch 400 can have a sealed state in which the blocking portion 410 is inserted into the through hole 231, and an open state in which the blocking portion 410 is separated from the through hole 231. In the sealed state, the latch 400 acts on the box body 100 to prevent the lid 200 from separating from the box body 100.

[0050] In the sealed container of the present application, the extension direction of the annular groove makes the demoulding direction of the entire box cover vertical. Compared with the existing technology, the size of the corresponding mold is reduced, the requirements for injection molding equipment are reduced, and thus the manufacturing cost is reduced.

[0051] The technical features of the above embodiments may be combined in any manner. To simplify the description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there are no conflicts in the combination of these technical features, they should be considered to be within the scope of this specification. When technical features in different embodiments are reflected in the same figure, it can be regarded as that figure also discloses the combination examples of the various embodiments involved.

[0052] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art could make numerous variations and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application.
