Easy-tear-open and tamper-evident container

An easy-tear-open and tamper-evident container comprising:

• a container body having a first convex loop on a periphery of an opening thereof;
• a lid having a second convex loop for engaging with the first convex loop, where a loop of tear line is provided on a topmost surface of the second convex loop, and the loop of tear line is divided into a section of breakable line and a section of broken line, the section of breakable line having a length larger than that of the broken line;
• and
• a spacer part being disposed below a local area of the topmost surface of the second convex loop that bears the section of broken line, and the spacer part being attached with the lid or the container body to make the local area bent up to form an 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 to remove a central area of the lid;
• and when an illegitimate user applies a lifting force on any local area of the second convex loop of the lid that corresponds to the section of breakable line to make the local area moving upward with a displacement exceeding a threshold, a corresponding local area of the section of breakable line will be broken to show that the tamper-evident container has been tampered with.
