ANTI-LEAK FOOD BOX

Abstract

The food box contains a box member and a cover member. The box member has a storage space with a top opening. At least a box flange extends from the top opening's circumference. An upward extending anti-leak wall surrounds the top opening. At least a first connection element is configured along the anti-leak wall. The cover member seals the top opening, and has at least a cover flange extending laterally from the cover member's circumference. An upward extending anti-leak ditch surrounds the circumference of the cover member compatible with the anti-leak wall. At least a second connection element is configured along the anti-leak ditch.

When the cover member seals the box member, the anti-leak wall is embedded into the anti-leak ditch so as to prevent a content of the food box from leaking.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims

[0028] As shown in FIGS. 1 and 2, a food box according to an embodiment of the present invention contains a box member 1 which has a storage space with a top opening. The box member 1 contains at least a box flange 11 extending laterally outward from a section of the top opening's circumference and an upward extending anti-leak wall 13 surrounding the top opening. At least a first connection element 12 is configured along the anti-leak wall 13. Each first connection element 12 has a first fastener 121. The food box further contains a cover member 2 edge-to-edge joined to the box member 1 so as to seal the top opening. The cover member 2 contains at least a cover flange 21 extending laterally outward from a section of the cover member 2's circumference and an upward extending anti-leak ditch 23 surrounding the circumference of the cover member 2. At least a second connection element 22 is configured along the anti-leak ditch 23. Each second connection element 22 has a second fastener 221. When the cover member 2 covers and seals the top opening of the box member 1, the anti-leak wall 13 is embedded into the anti-leak ditch 23, and each first connection element 12 is embedded into a corresponding second connection element 22 with their first and second fasteners 121 and 221 tightly matched with each other.

[0029] In the present embodiment, the cover member 2 and the box member 1 are integrally formed.

[0030] The first fastener 121 is configured in an upper section, a middle section, or a lower section on at least a laterally outward facing side of the first connection element 12.

[0031] Preferably, the first fastener 121 is an indentation.

[0032] The second fastener 221 is configured in an upper section, a middle section, or a lower section on at least a laterally outward facing side of the second connection element 22.

[0033] Preferably, the second fastener 221 is an indentation.

[0034] The first and second connection elements 12 and 22 have a block shape whose circumferential wall has a 3-like sectional shape.

[0035] The anti-leak ditch 23 has an inverted U-like sectional shape.

[0036] In alternative embodiments, the box member 1 and the cover member 2 have other compatible geometric shapes.

[0037] As shown in FIG. 3, when the cover member 2 seals the box member 1, the anti-leak wall 13 is embedded into the anti-leak ditch 23, and the first and second connection elements 12 and 22 are joined together. The first and second fasteners 121 and 221 are tightly fitted together so as to secure the connection between the first and second connection elements 12 and 22, which in turn locks the cover member 2 and the box member 1 reliably together, thereby preventing the content in the food box from splitting or leaking.

[0038] As shown in FIG. 4, to open the cover member 2, the box and cover flanges 11 and 21 provide convenient handles. In other words, by exerting a downward force on the box flange 11 and an upward force on the cover flange 21, the interlocking between the first and second connection elements 12 and 22 are disrupted, and the cover member 2 can be easily opened.

[0039] As shown in FIG. 5, in another embodiment of the present invention, the cover member 2 and the box member 1 are separately formed. The other details are identical to the previous embodiment.

[0040] As shown in FIG. 6, in yet another embodiment of the present invention, the first and second fasteners 121 and 221 are not confined to the first and second connection elements 12 and 22 only. In this embodiment, both the anti-leak wall 13 and the anti-leak ditch 23 have the first and second fasteners 121 and 221 configured along their entire circumferential sides, respectively.

[0041] While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the claims of the present invention.
