Abstract: Packing machines which manufacture packing containers of the so-called gable-top type from flexible packing laminate frequently handle prefabricated, tubular packing container blanks which are provided with a bottom section by folding in and sealing of a number of bottom wall panels. The bottom is pressed down and sealed while the blank is supported by a mandrel on a mandrel wheel.In order to avoid the transmission of the pressing and sealing forces to, and stressing of, the axle and bearing of the mandrel wheel, an arrangement is proposed which is designed so that the compressive forces generated by the pressure devices are absorbed by a tie rod which connects the pressure application arrangement with the axle of the mandrel wheel, so that the forces are absorbed internally without stressing the mandrel wheel axle or other surrounding elements.

Abstract: The invention describes an apparatus for the sterile packaging of flowable substances, comprising a conveyer belt (4), from one end of which open packages (5) can be passed by an intermediate conveyer means (21-23) through a sterilizing chamber (7) and to a second conveyer belt (13) disposed in a sterile chamber (15) enclosed in a housing (14), filling means (17) and sealing means (18) being disposed in this sterile chamber (15) while an outlet sluice (24) is disposed in a wall of the housing. In order to simplify and so further improve such an apparatus that a more effective sterilization process is achieved, it is according to the invention envisaged to construct the sterilizing chamber (15) as an inlet sluice (8).

Abstract: Packing containers of the non-returnable type for the packaging of milk, etc, frequently have a fold-out pouring spout which is intended to facilitate the pouring out of the milk in a concentrated jet.However, the air which must enter the package via the pouring spout at the same time as the pouring out takes place causes the flow to stop periodically so that the pouring out occurs jerkily.This disadvantage is overcome in accordance with the invention in that the spout is designed to have an emptying duct as well as an air duct. The air duct extends into the packing container over such a length that air can pass unhindered into the packing container without disturbing the flow of the contents through the pouring spout.

Abstract: Containers made of flexible material often have opening arrangements in the form of a tear strip for opening an outlet aperture. The tear strip constitutes a part of the container wall and is limited by a weakening line. To facilitate initiation of the tear-open operation a short length of the weakened line has the form of a cut or cuts extending fully through the material. Two or more cuts may form a lug or projection, and if located at a fold line of the container blank the lug or projection may be arranged to automatically extend outwards from the finished container.

Abstract: The invention, relating to cylindrical or prismatic, disposable containers for liquids, which containers have top and bottom end closures, comprises forming an end closure from a disk which is fixed to an end opening region of the container body by fusing together the common contact surfaces of the disk and said region or by means of a heat-activatable bonding agent.
