Abstract: Gas-tight packages for enclosing solid articles such as chocolates and other non-perishable baked goods in the form of a tubular pouch package which is easily opened and can be stream lined wherein the pouch has a gas-tight envelope made of a flexible sheet-like packaging material provided with zones where the packaging material is doubled and with a tear-open means.

Abstract: A package for packaging solid products with a wrapping formed from a flat, foldable packaging material and provided with a means to aid in opening the wrapping, the wrapping having a strip-shaped lamination segment of the packaging material formed by two layers of the packaging material joined together by a strip-shaped bonding segment, perforations and/or material weaknesses being provided in the strip-shaped bonding segment (15,20,26,32) as the means to aid opening situated in one of the two layers (11,18,27,33) of the lamination segment (2,17,25,31).

Abstract: A bottle closure cap stampable from sheet metal as a shallow cylindrical inverted dish having a rounded juncture forming a fillet between its crown and its cylindrical wall; a layer of elastomeric material being disposed in the fillet and engageable with the axial end of the bottle when the cap is attached. A generally radially extending rip tab is integral with the cylindrical wall at the bottom edge thereof and is adapted to tear through the cylindrical wall by a generally circumferential pull of the user to gain access to the container. A rip line is provided commencing at a corner defined by the bottom edge of the cylindrical wall where it meets the rip tab. The rip line extends at a shallow angle across the cylindrical wall to a level which is spaced below the crown, continuing parallel to the crown circumferentially about half-way around the closure cap.

Abstract: A process for the preparation of an improved base for offset printing plates comprising superimposing together two prerolled aluminum ribbons with an individual thickness of 0.12 to 0.5 mm, rolling the said superimposed ribbons to an individual ribbon thickness of 0.08 to 0.22 mm whereby the mutual contact surfaces have an uniform surface roughness, separating the two ribbons and forming a stable aluminum oxide layer on the uniformly roughened surfaces which have improved properties when used as a base for offset printing plates.
