Container that prevents from an illegal operation and can be easily identified after being illegally operated

Abstract

Disclosed is a container that prevents illegal operations and can be easily identified after being illegally operated. The container has a tension-breaking type buckle member having an annular tear line including connecting ribs and slits spaced apart from the annular tear line. A longitudinal line is defined by the middle point of the outer edge of the pull piece extending through the center point of the annular tear line, and the center of the annular tear line defines horizontal and longitudinal lines orthogonal to each other. The container further includes a weakening strength unit of tear line with a first weakening slit formed on both sides of the annular tear line close to the two sides of the pull tab. The extension length of the first weakening slit is between the angle range of plus or minus 15 to 20 degrees with the horizontal line as the center point.

I claim: 
     
         1 . A container that prevents from an illegal operation and can be easily identified after being illegally operated, said container comprising:
 a box body, including an opening and a first joining edge configured around the opening;   a cover body, optionally covering the opening of the box body, the periphery of said cover body configured with a second joining edge to fit the first joining edge configured on the box body;   a pull tab, formed on the second joining edge of the cover body, protruding outward, said pull tab including an external end edge and two side edges;   a tension-breaking type buckle member, including a buckle convex portion configured on the pull tab, a buckling slot configured at a position on the box body for the buckle convex portion to align and fix, and a ring tear line configured on the periphery of the buckle convex portion, thus, when the pull tab is pulled, the ring tear line will break and leave the buckle convex portion in the buckling slot, said ring tear line including a plurality of connecting ribs circularly distributed with intervals, and a plurality of slits relatively formed between the neighboring connecting ribs in a hollowed-out state; moreover, the peripheral area of the buckle convex portion of the pull tab and the peripheral area of the buckling slot of the box body are pushed together face to face, under the face-to-face contacting state, the pull tab protrudes outside the first joining edge of the box body to facilitate pulling, whereas the ring tear line is correspondingly configured inside the first joining edge of the box body; furthermore, extending from the center point of external end edge of the pull tab to the center point of the circle formed by the ring tear line, a longitudinal line is defined, and the center of the ring tear line further defines a horizontal line, said horizontal line and said longitudinal line being orthogonal to each other;   a pull tab strength weakening portion, configured on the structure of the pull tab, formed in a flat state, capable of bending, wherein the ring tear line is configured around the periphery of the buckle convex portion at an interval, so that the pull tab strength weakening portion is constituted by the narrow area existing between the ring tear line and the side edge of the pull tab, said pull tab strength weakening portion being used to cause the pull tab to have a bent portion when pulled up, so that the pull tab will turn up for easy identification; and   a weakening strength unit of the tear line, at least including a first weakening slit, said first weakening slit formed on the two sides of the ring tear line close to the two side edges of the pull tab, the extension length of said first weakening slit being between the angle range of plus or minus 15 to 20 degrees with the horizontal line as the center point.   
     
     
         2 . The container that prevents from an illegal operation and can be easily identified after being illegally operated defined in  claim 1 , wherein said weakening strength unit of the tear line further includes a second weakening slit, said second weakening slit formed at the side of the ring tear line close to the external end edge of the pull tab, the extension length of the second weakening slit being between the angle range of plus or minus 15 to 20 degrees with the longitudinal line as the center point. 
     
     
         3 . The container that prevents from an illegal operation and can be easily identified after being illegally operated defined in  claim 1 , wherein said weakening strength unit of the tear line further includes a third weakening slit, said third weakening slit formed at the side of the ring tear line away from the external end edge of the pull tab, the extension length of said third weakening slit being between the angle range of plus or minus 15 to 20 degrees with the longitudinal line as the center point. 
     
     
         4 . The container that prevents from an illegal operation and can be easily identified after being illegally operated defined in  claim 2 , wherein said weakening strength unit of the tear line further includes a third weakening slit, said third weakening slit formed at the side of the ring tear line away from the external end edge of the pull tab, the extension length of said third weakening slit being between the angle range of plus or minus 15 to 20 degrees with the longitudinal line as the center point. 
     
     
         5 . The container that prevents from an illegal operation and can be easily identified after being illegally operated defined in  claim 1 , wherein the extension lengths of said first weakening slit and said second weakening slit are equal to the distances between their respective neighboring connecting ribs.
