  • Tamper-proof capsules
    Patent number: 4893721
    Abstract: A hard shell tamper-proof capsule having cylindrical, telescopically joinable, coaxial cap and body parts each having a side wall, an open end and a closed end, the cap and body being adapted to be mutually joined; characterized in that the body closed end has either a generally hemispheroidal, a pyramidical, a conical or a flat outside surface, and that the body side wall is totally enclosed within the cap side wall thereby exposing only the outside surface of the body closed end for gripping, which impedes separation of and tampering with the joined capsule.For additional security the tamper-proof capsule may be provided with locking means of circumferentially extending ridges or grooves.For further security the tamper-proof capsule may be provided with sealing means such as hot water, steam, or hot solutions or emulsions.
