## Abstract

A tamper-evident container is disclosed. The tamper-evident container includes a containing base, a lid, and a release structure. The containing base has a base edge and the lid has a lid edge. The lid is fixed to the containing base for closing and the base edge encloses the lid edge. The release is disposed at the containing base. The release structure includes a barrier line and two break lines. The break lines are extended from two ends of the barrier line to the base edge. A detachable zone is encompassed by the barrier line, the break lines, and the base edge. The break lines are for detaching the detachable zone from the containing base, so that the lid edge is partially exposed so as to separate the lid from the containing base.

## Claims
