Abstract
A food container has a temporary rim formed in one-piece structure on the edge thereof. It has as first sealing rim and a second sealing rim as the surface for a sealing film to be heat-sealed thereon. When the outer rim is torn off, an irreversible tear-off structure on the sealed cover would leave the trace, allowing the consumers and the sellers to decide whether to purchase or dispose of the goods simply by visual judgments; in other words, it has a tamper-proof function. In addition, when the outer rim is removed from the container, the sealing film would detach from the first sealing rim but still stick on the second sealing rim, providing a reusable sealed cover for the container that ensures more safety of food hygiene.
Claims7
A one-piece food container with rim, comprising:
- a container formed by a bottom, a peripheral wall extending upwardly from an edge of said bottom, and an opening surrounded by said peripheral wall, and a first sealing rim surrounding a top edge of said opening and a first edge extending downwardly from a far edge of said first sealing rim;
- an outer rim formed in one-piece surrounding said first sealing rim, said outer rim having a second edge arranged next to said first edge and a second sealing rim surrounding said first sealing rim and a third edge extending downwardly from a far edge of said second sealing rim;
- and
- a tear-off structure arranged between the first edge and the second edge with a plurality of angularly spaced connection portions frangibly joining bottom ends of the first and second edges, the outer rim thereby being removably connected with the container and forming a one-piece container with rim;
- whereby upon a user removing said outer rim from said container, the tear-off structure between said first and second edges is irreversibly severed.

A one-piece food container with rim, comprising:
- a container formed by a bottom, a peripheral wall extending upwardly from an edge of said bottom, and an opening surrounded by said peripheral wall, and a first sealing rim surrounding a top edge of said opening and a first edge extending downwardly from a far edge of said first sealing rim;
- an outer rim formed in one-piece surrounding said first sealing rim, said outer rim having a second edge arranged next to said first edge and a second sealing rim at the same height as said first sealing rim and third edge extending downwardly from a far edge of said second sealing rim;
- and
- a tear-off structure arranged between the first edge and the second edge with a plurality of angularly spaced connection portions frangibly joining bottom ends of said first and second edges, the outer rim being thereby removably connected with the container and forming a one-piece container with rim;
- whereby upon a user removing said outer rim from said container, said tear-off structure between said first and second edges is irreversibly severed;
- and;
- a sealing film heat-sealed on respective surfaces of said first and second sealing rims, said sealing film remaining adhered to said outer rim and being disengaged with respect to said first sealing rim upon the outer rim being removed from said container, the sealing film being disposed in abutting relationship with respect to the first sealing rim responsive to said outer rim reengaging said container, and thereby forming a reusable structure covering the opening of the container.

A one-piece food container with rim, comprising
- a container formed by a bottom, a peripheral wall extending upwardly from the edge of said bottom, and an opening being surrounded by said peripheral wall and having a first sealing rim surrounding the top edge of said opening and forming a first edge downwardly from the far edge of said first sealing rim;
- an outer rim formed in one-piece on the far edge of the first edge, having a second edge arranged next to said first edge and a second sealing rim surrounding said first sealing rim and forming a third edge downwardly from the far edge of said second sealing rim;
- and
- a tear-off structure arranged along the link between the first edge and the second edge with a plurality of dividing dotted lines arranged regularly as the bottom end of the second edge sticking to the middle section of the first edge, resulting the second sealing rim being disposed higher than the first sealing rim, connecting the outer rim with the container temporarily and therefore forming a one-piece container with rim;
- whereby the surface of the second sealing rim becomes the place for a sealing film to be heat-sealed thereon, forming an irreversible tear-off structure that allows the consumers and the sellers to decide whether to purchase or dispose of the goods simply by visual judgments;
- when the outer rim is removed, the heat-sealed sealing film would detach from the edge of the container but would not be torn off from the surface of the second sealing rim, forming an reusable structure that can cover the opening of the container repeatedly.
