  • Patent number: 5906288
    Abstract: A cover for plastic pails having a dispensing closure adjacent the cover periphery which allows unimpeded flow of liquid from the pail. An anti-glug vent device is integrally molded in the cover diametrically opposite from the dispensing closure to permit surge free, controlled pouring. A vent panel is disposed in the central top wall of the cover bounded by a cutting zone of reduced cross section and a hinge connection to the cover. An axially disposed actuating lever extends upwardly from the central area of the vent panel. To activate the vent for smooth pouring, the cutting zone is cut with a knife or punctured with a screw driver allowing the vent to open by pushing the actuating lever away from the cutting zone causing the vent panel to pivot about the hinge connection. To reclose the vent, the pivoting action on the actuating lever is reversed causing the cutting zone on the vent panel to become frictionally engaged within the resulting opening in the pail cover.

  • Patent number: 4928845
    Abstract: The invention deals with an end face (1) with tear-away lip closure (3) for a pressurized container. Upon opening the tear-away lip (3), often the contents of the container are sprayed around because of the high internal pressure and the formation of foam after shaking the container. To remedy this disadvantage of known containers, a throttle device (5) for controlled release of the excess pressure is applied over the hole which is formed on tearing open the first section of the lip closure (3). This throttle device can be applied to both lip closures which are completely removed from the end face, as well as lip closures which stay attached to the end face and which are pushed into the inner space of the container.

  • Patent number: 4815655
    Abstract: Non-returnable packages for liquid contents, e.g. milk, are made frequently from a flexible packing laminate, and are provided with an opening arrangement in the form of a tear-off strip which covers a pouring opening in the packing container wall. So as to avoid spatter and spillage at the actual moment of opening, an opening arrangement for packing containers is realized comprising a pouring opening (8) which has a projection (8') of small area directed against the direction of tearing of the tearing strip (6). This part of the pouring opening (8) formed as a projection (8') thus will be opened first, and air will flow into the packing container, and the liquid level will drop so that the continued opening can be performed without any risk of spillage.

  • Patent number: 4705186
    Abstract: A can end assembly formed from interconnected elements of a cover portion, a tear-shaped seal member and a pull member. This assembly encloses an end of a container, such as a beverage can. The cover portion has a dispensing opening and vent and a pivotable connection to one end of the seal member. The other end of the seal member is pivotably connected to the pull member. In a first position, the seal member will close the opening and will be beneath the pull member. Upon a slight lifting of the pull member, a seal between the seal member and opening will be broken. Continued movement of the pull member causes the seal member to rotate 180 degrees about its connection to the cover portion. During this movement, the pull member also rotates 180 degrees about its longitudinal axis and is displaced about 90 degrees relative to its initial orientation.
