A tamper-evident food container includes a container body and a cover respectively having a coupling flange with sealing structure, and the cover has an enlarged surface, a frangible score line, and a pull tab on at least one end of the frangible score line. when the cover fastens to the container body, the plurality of the male engaging members are fixed into the female engaging members and the downward hem is inserted into the recessed portion; when opening the cover, upward pulling the pull tab to tear the frangible score line for detaching the cover from the second enlarged surface. Thus, the present invention ensures the integrity, security, and the ability to maintain high quality the food reserved in the tamper-evident food container.

1. A tamper-evident food container, comprising: a container body including a first coupling flange extended around a rim thereof, the first coupling flange having a first horizontal section and a first vertical section, a first endless concave formed in the first horizontal section at an upper side
1. A tamper-evident food container, comprising: a container body including a first coupling flange extended around a rim thereof, the first coupling flange having a first horizontal section and a first vertical section, a first endless concave formed in the first horizontal section at an upper side and extended around the container body, and a second endless concave portion formed in the first vertical section at an inner side and extended around the container body;a cover including a second coupling flange extended around a rim thereof for fastening to the first coupling flange of the container body, the second coupling flange having a second horizontal section and a second vertical section respectively fitting the first horizontal section and first vertical section, a first endless convex portion formed in the second horizontal section at a bottom side and extended around the cover for engaging the first endless concave portion of the container body, and a second endless convex portion formed in the second vertical section at an outer side and extended around the cover for engaging the second endless concave portion of the container body; whereby, when the cover fastens to the container body, the first endless convex portion and second endless convex portion of the cover are respectively press-fitted into engagement with the first endless concave portion and second endless concave portion of the container body, and therefore the food container is well sealed;wherein the container body includes a first horizontal surface extended from both outer sides of the first vertical section, the container body further includes a first enlarged surface extended from a front side of the first vertical section, said first enlarged surface has an area larger than said first horizontal surface, and the first enlarged surface has a plurality of female engaging members with a first engaging edge; a raised portion is formed at an outer edge of at least three sides of the first horizontal surface and the first enlarged surface, and a recessed portion is formed between an inner periphery of the raised portion and an interconnected surface of the first horizontal surface and first enlarged surface;the cover corresponding to the first horizontal surface has a second horizontal surface extended from said outer side of the second vertical section extending around said cover and corresponding to the first enlarged surface has a second enlarged surface extended from a front side of the second vertical section, and the second enlarged surface has a plurality of male engaging members with a second engaging edge for engaging the first engaging edge; a hem is formed at an outer periphery of the second horizontal surface for fitting within the recessed portion, and a frangible score line is provided at an interface between the cover and the second enlarged surface; andthe cover has a pull tab on at least one end of the frangible score line;whereby when the cover fastens to the container body, the plurality of the male engaging members are fixed into the female engaging members and the downward hem is inserted into the recessed portion; when opening the cover, the pull tab is pulled upward to tear the frangible score line for detaching the cover from the second enlarged surface. 2. The tamper-evident food container as claimed in claim 1, further comprises a hinge part formed at an opposite side of the first enlarged surface of the container body and the second enlarged surface of the cover for rearward lifting the cover. 3. The tamper-evident food container as claimed in claim 1, further comprises a third enlarged surface and a fourth enlarged surface having the same structure with the first enlarged surface and the second enlarged surface is respectively formed at an opposite side of the first enlarged surface of the container body and the second enlarged surface of the cover, a frangible score line is provided at an interface between the cover and the third enlarged surface for detaching the cover from the third enlarged surface, and a pull tab is formed at an end of the frangible score line.
