ABSTRACT:
The present invention provides a device for fixedly securing a cap and body of a capsule together to thereby render the capsule tamper evident. In one form of the invention, the capsules are conveyed at spaced intervals along a predetermined path of travel through a treatment zone which is generally perpendicular to the longitudinal axis of the capsule. An elongated bar having a tapered edge and positioned within the treatment zone engages the side of the capsule to produce an indentation in the side of the capsule which increases in depth from the entry and to the exit end of the treatment zone. This indentation around the capsule hermetically seals the cap and body of the capsule together so that the cap and body cannot be separated without destruction of the capsule. In another form of the invention, the bar is increasingly heated along its length so that, in addition to forming an indentation circumferentially around the capsule, simultaneously hermetically seals the capsule cap and body together. In still another form of the invention, a rotating disc having an outer shaped edge is aligned to and frictionally engages the outer periphery of the capsule in order to produce the desired indentation in the capsule. The disc can be heated to produce a fluid (hermetic) seal between the capsule cap and body. In still another form of the invention, a two part heated embosser forms an indentation around the capsule. The capsule is then rotated and again engaged by the embosser to hermetically seal the capsule.
