Abstract
A sealed package comprising a container, intended for use or reuse as a drinking vessel, and a cover. The container has a cylindrical surface adjacent its mouth to receive a length of tape which, on one side, carries a layer of pressure sensitive adhesive, which can be peeled from the container without leaving objectionable residues. The tape carries a layer of heat-sealable material on its opposite face and this is heat sealed to an aluminium foil lid, also bearing a coating of a heat sealing material.
Claims7
Sealed package for use or reuse as a drinking vessel comprising a container having an essentially cylindrical surface adjacent the container mouth, a ring, formed of a length of tape-like material, adhered to said cylindrical surface by means of a layer of pressure sensitive adhesive carried by said tape-like material, said pressure sensitive adhesive being selected to be peelable from said container surface without leaving objectionable residues thereon, and a foil cover secured to said ring by means of a heat-sealable material.
A method of producing a sealed package comprising applying a length of tape-like material bearing a layer of a liquids-resistant pressure-sensitive adhesive on one surface, to an essentially cylindrical surface adjacent the mouth of a glass container, said length being sufficient to completely surround said cylindrical surface, filling said container, placing an aluminium foil disc over the mouth of the filled glass container, folding down the edge of the disc around the mouth of the container to contact said length of tape-like material and sealing it to said length by means of a heat-sealable material under conditions of heat and pressure.
