Abstract
Abstract A tamper resistant, tamper evident container is formed of a vial having a barb or hook formed inside the open upper end, a cap adapted for insertion into the vial having a mating hook formed about the lower edge, and sealing rings formed on the outer surface thereof for providing tamper-resistant, leak-proof sealing between the enclosure and the vial. The enclosure or cap also includes a spout which may extend inwardly into the enclosure or outwardly, away from the enclosure. In a preferred embodiment, the spout has an integral seal member defined at the top or bottom thereof by a circumferential parting line of reduced thickness for facilitating separation of the seal member from the spout. Removable or locking plugs may be used to seal the spout following opening thereof. Preferably, a liquid-proof identification label is used which is placed inside the vial prior to closure. This label may include temperature sensitive indicia which change colors at selected temperatures, for example, above and below the normal body temperature, for providing additional proof of non-tampered contents.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
232 words
Joinable components for a tamper resistant, tamper evident container, comprising: a cup of hard, relatively rigid material comprising an annular sidewall and having a closed bottom end and an open upper end, said cup having inwardly extending peripheral first lip means formed about the upper inner surface thereof; a cover of size and configuration for insertion into the open end of the cup, said cover comprising a hard, relatively flexible, annular sidewall and having outwardly extending, peripheral second lip means formed about the outer surface thereof, the relative flexibility of said cover permitting insertion of the second lip means into the cup to engage said first lip means and, in combination with the relative rigidity of said cup and first lip means, providing secure locking engagement of the first and second lip means, and said cover further comprising an integral tubular spout having top and bottom ends and a sealing member across the spout; and a lockable plug for the spout comprising an open tubular body of size and configuration adapted for sliding insertion into the spout, said body having a cap formed on the upper end thereof, peripheral third lip means extending laterally from said upper end and peripheral fourth lip means extending laterally from the bottom thereof, said plug lip means being spaced apart a selected distance for locking the plug onto the top and bottom ends of the spout.
Claim 2
Dependent Claim
