摘要 |
A tamper-proof seal for a container having at least one circumferentially extending flange adjacent the discharge opening therein comprising an annular top and a circumferentially extending skirt depending from the top adapted to be crimped at its lower terminal edge to engage under the flange to hold it on the container. A pull ring connects to the annular portion by a throat portion and partial score lines extend across the annular top portion on either side of the pull ring and define a plurality of circumferentially spaced score lines extending from the lower edge of the skirt upwardly in an axial direction to a point closely adjacent the juncture of the skirt and annular top portion. The axial score lines are spaced closely about the skirt.
