Abstract
A container closure having an originality ring which can be attached to a container with little force and easily removed, while making certain that the originality ring either detaches completely from the closure cap or is at least damaged visibly. The retaining elements comprise a rocker having first and second legs connected to the originality ring via an elastic web. The first leg points obliquely inward and the second leg points outward.
Claims11
A closure cap (2) for a container (16) having an annular bead (18), said closure cap having a free circumferential rim and having at its free circumferential rim a break-away originality ring (7) with upper and lower edges, said originality ring being provided with retaining elements which cooperate with the annular bead (18) of the container (16), characterized in that the retaining elements comprise a plurality of individual rockers (8) each with a first leg (9) and a second leg (10) which are angularly connected to each other at a common fulcrum joint which is connected solely to the originality ring (7) by an elastic web (11) disposed intermediate the upper and lower edges of said originality ring, said first leg (9) pointing obliquely inward relative to the closure cap (2) and said second leg 910) pointing down, and said second leg (10) being disposed at an obtuse angle with respect to said first leg (9).
A closure cap (2) for a container 916) having an annular bead (18), said closure cap having a free circumferential rim and having at its free circumferential rim an originality ring (7) provided with retaining elements which cooperate with the annular bead (18) of the container (16), characterized in that the retaining elements comprise rockers (8) each with a first leg (9) and a second leg (10) which are connected to the originality ring (7) by an elastic web (11) that is common to both, said first leg (9) pointing obliquely inward relative to the closure cap (2) and said second leg (10) pointing down, and further characterized in that the originality ring (7) has a section (25) in which no rockers are located and the originality ring (7) having a predetermined breaking point of weakness 923), the rockers (8) being provided only unilaterally adjacent to the point of weakness (23) and the originality ring (7) being connected to the closure cap (2) only in said section (25) in which no rockers (8) are located.
A closure cap (2) for a container (16) having an annular bead (18), said closure cap (2) having a free circumferential rim and having at its free circumferential rim a break-away originality ring (7), said originality ring having an inner surface and being provided with retaining elements which cooperate with the annular bead (18) of the container 916), said retaining elements comprising a plurality of individual pivotally movable rocker legs (9) engageable with said annular bead (18) and movable between retracted positions enabling the legs (9) to be shifted past the annular bead (18), and extended blocking positions which prevent the legs (9) from being shifted past the annular bead (18), characterized by abuttable uni-directional blocking means located within the originality ring (7) for preventing pivotal movement of said pivotally movable legs (9) past their extended blocking positions, said blocking means comprising control rocker legs (10) respectively attached to and rigid with respect to the pivotally movable rocker legs (9), said control legs (10) being engageable with the inner surface of the originality ring (7) when the pivotally movable rocker legs (9) are in their extended blocking positions.
