A tamper-proof and easy-open sealing type food container includes a container body and a lid. A peripheral wall of the container body has at least one recessed wall portion disposed in one corner thereof and formed a retracted external space area and concave camber between the recessed wall portion and a hem. A pull tab extends from outside of a sealing rib that can be inserted into the concave camber. Moreover, there are two tamper-proof structures disposed on the lid. The first is that the first score line has to be poked through, and the second is the second score line needs to be torn off when opening the lid. When either structure is tampered, it could be easily distinguished, which ensures the integrity, safety, and qualities of the food inside the container. With these features plus its sealing effect, the present invention has dual function of tamper-proofing and easy-opening.

1. A tamper-proof and easy-open sealing type food container comprising: a container body including a bottom wall and a peripheral wall upwardly extended from the border thereof, said peripheral wall defining a top edge, a first sealing rib and a third sealing rib extending along the top edge of said
1. A tamper-proof and easy-open sealing type food container comprising: a container body including a bottom wall and a peripheral wall upwardly extended from the border thereof, said peripheral wall defining a top edge, a first sealing rib and a third sealing rib extending along the top edge of said peripheral wall and linking up with each other, a hem extended transversely from said first and third sealing ribs relative to said peripheral wall, and a lip disposed adjacent said third sealing rib with a concave camber defined thereon; andlid releasably fastened to the container body, the lid defining an edge, the lid including a second sealing rib and a fourth sealing rib extending along the edge, the second and fourth sealing ribs respectively fitting to retentively engage said first and third sealing ribs and thereby releasably fasten the lid to the container body when closed thereover, in order to prevent liquid inside from leakage, a pull tab configured to cover said concave camber when the lid is closed, said pull tab extending from said fourth sealing rib and initially secured to the lid along a breakable first score line having an irreparable design upon breaking to provide a visible indication thereof;wherein the lid is initially attached to the container body along a breakable second score line, said second score line extending alongside a portion of said second sealing rib of the lid; and, said pull tab is arranged adjacent an end of said second score line to facilitate breakage thereof responsive to the pull tab being upwardly drawn from said concave camber. 2. The tamper-proof and easy-open sealing type food container as claimed in claim 1, wherein: each of the first and third sealing ribs has a first horizontal sealing face and a first vertical sealing face,a first sealing groove is defined on each first horizontal sealing face, and a second sealing groove is defined on each first vertical sealing face,each of the second and fourth sealing rib has a second horizontal sealing face and a second vertical sealing face, anda first engagement protrusion is defined on each second horizontal sealing face, and a second engagement protrusion is defined on each second vertical sealing face,when the lid is closed over the container body, said first and second sealing groove fittingly engage said first and second engagement protrusion in order to prevent leakage. 3. The tamper-proof and easy-open sealing type food container as claimed in claim 1, wherein said first score line of the pull tab is arranged substantially in an H shape. 4. The tamper-proof and easy-open sealing type food container as claimed in claim 2, wherein said first score line of the pull tab is arranged substantially in an H shape. 5. The tamper-proof and easy-open sealing type food container as claimed in claim 3, wherein said pull tab has a coarse surface. 6. The tamper-proof and easy-open sealing type food container as claimed in claim 4, wherein said pull tab has a coarse surface. 7. The tamper-proof and easy-open sealing type food container as claimed in claim 1, wherein said first score line shapes a geometric figure depressible into the concave camber upon breakage of said first score line when the pull tab is pressed to open the lid, a hole for hooking engagement by a finger being thereby formed. 8. The tamper-proof and easy-open sealing type food container as claimed in claim 2, wherein said first score line shapes a geometric figure depressible into the concave camber upon breakage of said first score line when the pull tab is pressed to open the lid, a hole for hooking engagement by a finger being thereby formed.
