Abstract: An inviolable cap for a flask which provides proof when tampered with. The cap has an interconnecting wall in a region where the body and the band of the cap adjoin one another. The wall includes a plurality of cut segments aligned in a circular fashion thereabout separated by a plurality of transverse interruptions, with one of the interruptions being at least twice as long as any of the cut segments and the rest of the transverse interruptions being substantially shorter than any of the cut segments. The band further includes a vertical cut with vertical interruptions. A projection on the band fits about a collar on the flask. When the cap is unscrewed, the shorter transverse and the vertical interruptions sever.

Abstract: A "device for applying a cap and seal to the mouth of a bottle whereon an interference boss is provided for said seal" comprising a cylindrical body [1] having upper means [2] for fitting it to a conventional machine so that the assembly may, simultaneously, be rotated and moved alternately upward and downward. Means [3] are provided on the inside thereof to enable stable penetration and ejection of a non-descript cap and seal, the latter being steadied by movable external means [4] duly protected by an outer enclosure [5]. In this way, a cap is screwed onto a conventional bottle with a seal coupled to an interference boss provided on the neck of the said bottle.
