Tamper-proof container and cap assembly

A tamper-proof container and cap for indicating whether the container has been opened, comprising:

• a destructible projection extending from one toward the other of said container and cap, said projection including a stem integrally molded with said one of said container and cap and at least one laterally extending flange at a free end of said stem, said stem including a single weakened point of reduced cross section disposed at an end of said stem opposite said free end thereof, a cross piece projecting laterally from said stem at a location intermediate said free end and said weakened point, said cross piece being coplanar with said stem and said flange,
• an elongated slot formed in the other of said container and cap and receiving said free end of said projection, said flange extending laterally beyond an edge of said slot such that said cap can be opened only in response to breakage of said projection at said weakened point, said slot being situated between said flange and cross piece to prevent separation of said projection from said other of said container and cap after said projection has been broken,
• said cap being molded of one-piece with said container, and said cap and container being molded of plastic.
