  • Patent number: 6439411
    Abstract: A container closure system comprises a container having an opening zone (21) with a threaded neck (22). A closure cap (23) can be screwed on the threaded neck (22). A warranty element comprises an annular base body (25) with engagement means which can engage matching engagement means (38) in the opening zone (21) of the container. The warranty element also comprises one or more indicator elements (27) shaped as circle segments and linked each by a predetermined breaking strip to the base body (25). The closure cap (23) has at least one axial projection (34) which can be inserted between the ends of the indicator elements (27) shaped as circle segments or between the ends of two adjacent indicator elements (27) in order to secure the indicator elements (27) against rotation to the closure cap (23). When the closure cap (23) is unscrewed, these axial projections (34) break the predetermined breaking strips, separating the indicator elements (27) shaped as circle segments from the base body (25).

  • Patent number: 6419117
    Abstract: A plastic reinforcement engaging the end wall of a bag tube includes an outlet surrounded by an outwardly extending flange which has the same curvature as the end wall and extends. This construction stiffens the stiffens the end wall and reduces the risk of the tube tipping over which it is rested upside down on its cap.

  • Patent number: 4735761
    Abstract: The tubular body is laid in a horizontal position on a tapered suction drum and pivoted thereby into a vertical axis which is in coaxial relationship with the axis of a mandrel with a punch. The tubular body is then pushed from the surface of the suction drum on to the mandrel by a thrust member. The mandrel and/or the die is mounted displaceably in a vertical direction, which permits particularly stable and precise guidance. A plurality of dies with mandrels and punches associated therewith is disposed on a rotary member. In the course of a revolution of the rotary member, the tubular body on the mandrel is connected to a squeeze moulding in the die.

  • Patent number: 4237939
    Abstract: A stackable tapered tube body has an annular inwardly directed bead or corrugation in the region of the sealant layer. This provides that the tube bodies do not touch each other directly and that in particular the sealant layer is protected when tube bodies are stacked together.The beads or corrugations are produced by the tube shell being gripped substantially over its entire periphery, and deformed.
