Abstract
A tamper-indicating capped container includes an indicating member sealed across the container access port and the container cap is transparent and has capability for effecting visible change in the indicating member selectively in the course of container-opening sense movement of the cap. Tines may depend in cantilever manner from the cap interior to provide for tearing of the indicating member and the indicating member may be paper sheet material or a color change telltale.
Claims16
A tamper-indicating container comprising:
- (a) a vessel for article containment and having an access opening:
- (b) a closure member having means for supporting said closure member for first sense rotative movement relative to said vessel into securement therewith and in circumscribing relation to said access opening of said vessel and for second different rotative sense movement for release from such securement, said closure member providing visibility therethrough;
- (c) sealing means in secured relation to said access opening for closing same and including a telltale and;
- (d) means depending from an upper interior surface of said closure member and inaccessible therethrough for travel with said closure member relative to said telltale in engaged non-rupturing relation to said telltale in the course of said closure member first sense movement and for travel with said closure member in engaged rupturing relation to said telltale in the course of said closure member second different sense movement.

A container closure comprising:
- (a) a closure member having means for supporting said closure member for first sense rotative movement relative to a container into securement therewith and in circumscribing relation to an access opening of said container and for second different rotative sense movement for release from such securement, said closure member providing visibility therethrough;
- and
- (b) means dependent from an upper interior surface of said closure member and inaccessible therethrough for travel with said closure member and supported for deflection relative to said closure member in said first sense rotative movement of said closure and having orientation relative to said closure member for such deflection in said first sense movement of said closure member and for tearing a sealing member disposed across said container access opening in the course of said second different sense rotative movement of said closure member.
