Anti-tamper container

An anti-tamper container for preventing incorrect opening, comprising:

• a box body, comprising of:
• a bottom wall, a circumferential wall, an open end and a holding space;
• of which the circumferential wall further comprises of an inner and an outer ring surfaces;
• an abutting flanged portion, set integrally onto or near the open end of the box body to form a spacing ring concave on the box body;
• a cover, comprising of a front end and a rear end;
• the rear end of said cover is linked to the back of the open end of the box body via a coupling flange;
• said cover could be rotarily covered on the box body by taking the coupling flange as a pivot and abutted into the spacing ring concave;
• at least an incorrect opening preventing device, set on the front end of the cover correspondingly to the open end of the box body;
• said incorrect opening preventing device comprises of:
• a tilting extension sheet, which is extended downwards and gradually tilted forward on the front end of the cover;
• said tilting extension sheet comprises of:
• a front inclined surface and a rear inclined surface;
• a vertical through-hole, set on the open end of the box body correspondingly to the tilting extension sheet;
• when the cover is covered onto the box body, said tilting extension sheet could penetrate downwards the vertical through-hole;
• a pre-dislocated rib, formed in front of the vertical through-hole by a pre-dislocated line extended forwards from both ends of the vertical through-hole;
• when a force is applied to the cover to rotarily open it upwards, the front inclined surface of said tilting extension sheet could press the pre-dislocated rib to disengage it from the box body against reconnection, enabling a person to easily recognize if the cover has been incorrectly opened.
