  • Patent number: 7588030
    Abstract: A medicament container and a method of manufacturing the container housing at least one individual dose of medicament using a carrier having first and second opposing faces and through walls defining a through hole extending between the first and second opposing faces, the method including inserting the carrier into a mould having an element for protrusion into the through hole from the first face so as to define with the through walls a generally cup-shaped space, filling the generally cup-shaped space with a mould material so as to form a generally cup-shaped insert in the through hole, removing the carrier and insert from the mould, depositing an individual dose of medicament in the generally cup-shaped insert, and sealing the medicament and insert in the through hole by sealing first and second sheets respectively with the first and second faces.

  • Patent number: 5660867
    Abstract: Devices are described for fitting into pressurized individually packaged beverages (typically canned beers, ales and stouts), by which gas at high pressure is stored within the package for jetting into the beverage as the package is opened to atmosphere. One embodiment comprises a length of tube (10) having a gas jetting orifice (14) which in use is submerged below the beverage in a pressurized can having a gaseous headspace, which can be used to charge the tube with gas during the passage of the filled can (16) along a conventional canning line, on which the can is inverted after filling which brings the orifice into the gaseous headspace.
