Detailed ways:

The above and other objects and advantages of the present invention can be easily understood from the following detailed description of selected embodiments and accompanying drawings.

Of course, the present invention allows some differences in some components or the arrangement of components, but the selected embodiments are described in detail in this specification and their structures are shown in the accompanying drawings.

Please refer to FIG. 1 to FIG. 3 , which show the structure of the selected embodiment of the present invention, which is for illustration only, and is not limited by this structure in the patent application.

This embodiment provides an anti-theft container closure structure, which includes a can body 2 and at least one cover body 1. In this embodiment, the top and bottom ends of the can body 2 respectively have an opening 20, and the two cover The body 1 respectively closes the openings 20 of the tank body 2, wherein:

As shown in Figures 1 to 2, each cover body 1 has a bottom plate 10, and a ring wall 11 is arranged around the bottom plate 10, and an outer convex portion 12 is formed along the top of the ring wall 11, and the outer convex portion 12 The top of the ring wall 11 is bent outwards to protrude, and the ring wall 11 is provided with a ring groove 13 near the outer convex part 12. The ring groove 13 is recessed into the ring wall 11, and the top and bottom of the tank body 2 Each end has an inner convex portion 21 protruding toward the opening 20, and the two lids 1 are positioned by engaging the inner convex portion 21 at the top and bottom of the can body 2 with a ring groove 13, and are closed in this embodiment. The lid body 1 at the top of the can body 2 has a bottom plate 10 provided with a pull ring 100 for the can.

As shown in Figures 1 to 2, each cover body 1 has several cuts 14 along the top of the ring wall 11, and each cut 14 is cut longitudinally from the convex part 12 toward the ring wall 11. The notch 14 means that it has not been cut. The cover body 1 forms a detachable part 15 between any two notches 14, and the detachable part 15 can be easily peeled off by the notch 14.

As shown in Figures 2 to 3, when the thief wants to steal the contents of the tank body 2, he inserts a tool 3 (a flat-head screwdriver as shown in the figure) between the top of the tank body 2 and the convex part 12 of the lid body 1. The joint 4 of the can body 2, or the seam 4 between the bottom end of the tank body 2 and the convex part 12 of the cover body 1, and when the convex part 12 of any cover body 1 is pried, the detachable part 15 is pried And when the cut marks 14 on both sides are peeled off, the detachable part 15 at this time will be lifted separately along the direction of tool prying as shown in Figure 3. Since the detachable part 15 has been separated, it still cannot be separated The prying part moves the whole cover body 1 off the tank body 2, and several adjacent detachable parts 15 must be pried to lift the cover body 1 off the tank body 2, and the integrity of the cover body 1 is destroyed at this time. Therefore, it is easy to find the traces that have been pried, and the vigilance that is easy to be found will be generated for the thief, and the effect of deterring theft can be achieved relatively.
