An easy-tear-open and tamper-evident container (100, 200, 300, 400) comprising: a container body (110, 210, 310, 410) having a first convex loop (111, 211, 311, 411) on a periphery of an opening thereof; a lid (120, 220, 320, 420) having a second convex loop (121, 221, 321, 421) for engaging with the first convex loop (111, 211, 311, 411), characterised in that a loop of tear line (1211, 2211, 3211, 4211) is provided on a topmost surface of the second convex loop (121, 221, 321, 421), and the loop of tear line (1211, 2211, 3211, 4211) is divided into a section of breakable line (1211a, 2211a, 3211a, 4211a) and a section of broken line (1211b, 2211b, 3211b, 4211b), the section of breakable line (1211a, 2211a, 3211a, 4211a) having a length larger than that of the broken line (1211b, 2211b, 3211b, 4211b); and a spacer part (111a, 2211c, 3211c, 4211c) being disposed below a local area of the topmost surface of the second convex loop (121, 221, 321, 421) that bears the section of broken line (1211b, 2211b, 3211b, 4211b), and the spacer part (111a, 2211c, 3211c, 4211c) being attached with the lid (120, 220, 320, 420) or the container body (110, 210, 310, 410) to make the local area bent up to form a force application part; where, when in a normal opening operation, the force application part is used for a user to apply a force thereon to break the section of breakable line (1211a, 2211a, 3211a, 4211a) to remove a central area of the lid (120, 220, 320, 420); and when an illegitimate user applies a lifting force on any local area of the second convex loop (121, 221, 321, 421) of the lid (120, 220, 320, 420) that corresponds to the section of breakable line (1211a, 2211a, 3211a, 4211a) to make the local area moving upward with a displacement exceeding a threshold, a corresponding local area of the section of breakable line (1211a, 2211a, 3211a, 4211a) will be broken to show that the tamper-evident container (100, 200, 300, 400) has been tampered with. a container body (110, 210, 310, 410) having a first convex loop (111, 211, 311, 411) on a periphery of an opening thereof; a lid (120, 220, 320, 420) having a second convex loop (121, 221, 321, 421) for engaging with the first convex loop (111, 211, 311, 411), characterised in that a loop of tear line (1211, 2211, 3211, 4211) is provided on a topmost surface of the second convex loop (121, 221, 321, 421), and the loop of tear line (1211, 2211, 3211, 4211) is divided into a section of breakable line (1211a, 2211a, 3211a, 4211a) and a section of broken line (1211b, 2211b, 3211b, 4211b), the section of breakable line (1211a, 2211a, 3211a, 4211a) having a length larger than that of the broken line (1211b, 2211b, 3211b, 4211b); and a spacer part (111a, 2211c, 3211c, 4211c) being disposed below a local area of the topmost surface of the second convex loop (121, 221, 321, 421) that bears the section of broken line (1211b, 2211b, 3211b, 4211b), and the spacer part (111a, 2211c, 3211c, 4211c) being attached with the lid (120, 220, 320, 420) or the container body (110, 210, 310, 410) to make the local area bent up to form a force application part; where, when in a normal opening operation, the force application part is used for a user to apply a force thereon to break the section of breakable line (1211a, 2211a, 3211a, 4211a) to remove a central area of the lid (120, 220, 320, 420); and when an illegitimate user applies a lifting force on any local area of the second convex loop (121, 221, 321, 421) of the lid (120, 220, 320, 420) that corresponds to the section of breakable line (1211a, 2211a, 3211a, 4211a) to make the local area moving upward with a displacement exceeding a threshold, a corresponding local area of the section of breakable line (1211a, 2211a, 3211a, 4211a) will be broken to show that the tamper-evident container (100, 200, 300, 400) has been tampered with.
