[0023] The present application provides the following description with reference to the accompanying drawings to help comprehensively understand various embodiments of the present application as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as just exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the present application.

[0024] ​​In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0026] An embodiment of this utility model provides a lunch box with a flanged sealing structure, such as... Figures 1-4 As shown, the lunchbox includes a lunchbox body 100. The top of the lunchbox body 100 has an opening 110 through which food can be placed into or removed from the lunchbox body 100. The outer periphery of the opening 110 of the lunchbox body 100 is provided with a downwardly bent flange 200. The flange 200 and the outer side wall of the lunchbox body 100 form a receiving groove. The receiving groove is filled with a sealing body 300. Thus, the sealing body 300 seals the receiving groove, making it difficult for external dust and other impurities to enter the receiving groove, thereby preventing dirt and grime from accumulating on the inside of the flange 200 and making the lunchbox cleaner.

[0027] In some embodiments, the sealing body 300 is elastically deformable and fits tightly against the inner wall of the receiving groove. Because the sealing body 300 is elastically deformable, it is easy for the sealing body 300 to be inserted into the receiving groove. Under the action of the elastic restoring force, the sealing body 300 can be stretched outwards, thereby fitting tightly against the inner wall of the receiving groove. On the one hand, this allows the sealing body 300 to be firmly secured in the receiving groove; on the other hand, it improves the sealing performance, making it more difficult for external dust and other impurities to enter the receiving groove.

[0028] Furthermore, the seal 300 is made of silicone, rubber, or plastic, which allows the seal 300 to deform elastically and is relatively inexpensive.

[0029] The sealing body 300 can be manufactured first, and then inserted into the receiving groove. Alternatively, hot-melt material can be directly injected into the receiving groove, and the sealing body 300 can be directly formed in the receiving groove by injection molding.

[0030] In some embodiments, the sealing body 300 extends out of the containing groove, and the sealing body 300 extends out of the opening of the containing groove to occupy a part of the space outside the containing groove, thereby further increasing the difficulty of impurities entering the containing groove from outside. Meanwhile, the bottom surface of the sealing body 300 is located at a height lower than the bottom end of the flange 200, so that the user can contact the sealing body 300 when holding the entire lunch box, thereby improving the comfort of the user holding the lunch box and greatly reducing the probability of the user contacting the inner side of the lower end of the flange 200, thereby reducing the risk of the user being scratched.

[0031] In some embodiments, the flange 200 includes a first flange 210 extending laterally to the outside of the lunch box body 100 and a second flange 220 extending downwardly, the inner end (the end close to the lunch box body 100) of the first flange 210 is connected to the lunch box body 100, and the outer end (the end away from the lunch box body 100) of the first flange 210 is connected to the top end of the second flange 220. Thus, the first flange 210, the second flange 220 and the lunch box body 100 enclose the containing groove.

[0032] This structure makes the flange 200 have a certain thickness in the lateral direction, which facilitates the bending forming of the flange 200 and the manufacturing forming of the sealing body 300.

[0033] Further, the second flange 220 is arranged obliquely relative to the vertical direction and gradually approaches the lunch box body 100 in the downward extending direction. On the one hand, in the downward direction, the width of the opening at the bottom of the containing groove gradually decreases, so that the sealing body 300 is not easy to come off the containing groove and is stably installed in the containing groove. On the other hand, the edge of the lower end of the second flange 220 is equivalent to inwardly shrinked, so that the user is not easy to touch, thereby reducing the risk of the user being scratched.

[0034] In some embodiments, the connection between the first flange 210 and the lunch box body 100 is designed with a rounded corner, and the connection between the first flange 210 and the second flange 220 is designed with a rounded corner. The rounded corner design makes the connection smoother and not easy to scratch the user.

[0035] In some embodiments, the connection between the bottom surface of the sealing body 300 and the side surface of the sealing body 300 close to the second flange 220 is designed with a rounded corner. This design makes the connection between the bottom surface of the sealing body 300 and the side surface of the sealing body 300 close to the second flange 220 not easy to generate burrs after the sealing body 300 is formed, and the part of the sealing body 300 exposed outside is smoother.

[0036] In some embodiments, the inner side wall of the lunch box body 100 is provided with a step 120, which can expand the area of the opening 110 and facilitate the cover of the lunch box to be covered on the lunch box body 100.

[0037] The terms and words used in the above description and claims are not limited to the bibliographical meanings, but are merely used to enable a clear and complete understanding of the present application by those skilled in the art. Accordingly, it should be apparent to those skilled in the art that the above description of various embodiments of the present application is provided only to explain the present application and is not intended to limit the present application defined by the appended claims and their equivalents.
