Patent number: 4289236Abstract: This invention relates to a case can package wherein two twelve can-one-half case can packages are joined to form a one case can package by means of an overwrap. The package film of the one-half case can packages is provided on the outer surface thereof with a suitable overprint in the form of a resist which prevents bonding of the overwrap film thereto. The overwrap film interlocks with the cans of the two one-half case can packages to form a readily handleable one case package unit. The overwrap film is readily removable to present two one-half case can packages for individual sale. The overwrap joining the two one-half case can packages eliminates the need for the usual paper board tray, which is quite expensive, and at the same time provides for improved stacking of the can packages in case lots on pallets.Type: GrantFiled: September 26, 1979Date of Patent: September 15, 1981Assignee: Ganz Brothers, Inc.Inventors: Robert H.

Patent number: 4284196Abstract: It has been found that fluid, semi-fluid, plastic products as well as powder or granular products packed in plastic tubes have caused great problems in tropical countries due to the change in temperature between day and night. In some cases the products have expanded and burst open the closure of the plastic tube so that the contents ran out or, due to their constituents, the products have caused deterioration of the protective properties of the plastic tube. By choosing a plastic tube or olefin plastic and sealing said plastic tube with closures of olefin plastic, as well as orientating the plastic molecules in the tube in both axial and radial direction, a plastic seal is obtained which is not affected by the products enclosed and which also resists expansion of the products without rupturing.Type: GrantFiled: September 11, 1979Date of Patent: August 18, 1981Assignee: Nitro Nobel ABInventor: Conny B. Lagerkvist

Patent number: 4130201Abstract: This disclosure has to do with a bottle package of the type wherein at least four bottles arranged in two columns are formed into a package by wrapping a heat shrinkable plastics material film thereabout and effecting shrinking of that film to tightly grip bottles. In order to facilitate the carrying of the package, finger receiving openings are formed on opposite sides of central ones of the bottles with the film engaged over the top of the central ones of the bottles between the finger receiving openings defining a carrying strap. The shrinking of the film is effected in a shrink tunnel where hot air is directed against the film. The finger receiving openings are formed in the film between adjacent pairs of bottles after initial shrinking of the film has occurred, but before the film reaches the end of the shrink tunnel so that after slitting of the film occurs, there is further shrinking of the film, primarily down between adjacent pairs of bottles.Type: GrantFiled: October 19, 1976Date of Patent: December 19, 1978Assignee: Ganz Brothers, Inc.Inventor: Joseph W.
