  • Patent number: 4583665
    Abstract: A tamper-indicating closure system used with a container that has a sealing disc over the neck of the container. The closure threads onto the container neck but is held against threading down below a predetermined level by a rupturable tear band between the bottom of the closure and the shoulder of the container. A pourout dispenser feature is incorporated in the closure and after the tear band is removed, the continued threading-on of the closure will cause a member in the closure to rupture the sealing disc and the contents of the container can be poured therefrom through the closure. If the tear band is intact, tampering has not occurred.

  • Patent number: 4581054
    Abstract: An orifice ring and its holder are disclosed in detail, particularly as to the manner in which the ring is positioned within the holder or pan. The pan is formed with locating slots within which locating keys on the holder are to be positioned. Furthermore, the orifice holder or pan is provided with a precisely formed, horizontally extending slot along the center line of the diameter thereof which defines the four orifice openings. Vertical, side-locating pads, of which there are four in number on the bottom of the orifice ring, define parallel vertical planes at opposed sides of the orifices. These vertical planes coincide with the vertical planes defined by the horizontal slot formed in the pan. Four seating pads formed on the ring define a horizontal plane that is parallel to the top of the orifice ring. These seating pads support the ring in the bottom of the pan. These pads are juxtaposed the side-locating pads. In this manner, precise location of the orifice relative to the pan is provided.

  • Patent number: 4579614
    Abstract: An infrared heat tunnel with hot air circulation for heat shrinking wraparound labels on containers which are moved through the tunnel in an upright attitude on an open weave conveyor belt. The infrared heating is by electrical strip heaters along the sides of the tunnel and air is blown by blowers across these heaters to impinge on the sides of the containers. The air is drawn down through the conveyor belt since the inlet to the blowers is from beneath the conveyor. A vertical air curtain along each side of the first half of the tunnel is adjustable in length to effectively delay the skin shrinkage of the film-foam material of the labels in order to get wrinkle-free shrinkage of the film and underlying foam about the container wall and heel areas without bottle rotation.

  • Patent number: 4578857
    Abstract: A tamperproof package comprising a container having a neck and an annular radial flange beneath the neck and a plastic closure removably interengaged with the neck. The closure has a top wall and a peripheral skirt. A plastic pilfer band interengages the skirt, such that when the closure is applied to the container, the band is flexed over and engages beneath annular flange on the neck of the container, and when the closure is thereafter removed from the container, the band is prevented from removal from the container and is thereby disengaged from the closure. In a modified form the plastic pilfer band includes an integral liner which is severed from the band and engages the top wall of the closure during assembly of the band to the closure.
