Abstract: This invention relates to a method of moving a plurality of two-piece canning jar-type lids in series to a feed mechanism which will single-line the caps and maintain them in assembled position. The single-lining is arranged to approach the path of movement of a plurality of containers also moving in series on their side with their axes horizontal. The caps are brought, under gravity and at an angle, to the path of movement of the finish or neck of the jars such that the finish of the jars or containers individually engage and move the caps from the supply of caps. The caps are then retained on the finish of the jar and by reason of the movement with the jar, in a linear path, the caps are rotated and thereby threaded onto the finish of the containers.

Abstract: An inline magnetic mixer for flowing fluids. A magnetic particle is contained within a flow tube through which a fluid passes. A coil made of electrically conductive material is positioned in close proximity to the flow tube and outside the flow tube. A low voltage, oscillating electrical supply energizes the coil. This sets up an oscillating magnetic field within the flow tube which causes the magnetic particle to oscillate longitudinally within the flow tube, thereby mixing the fluid stream passing through the flow tube.

Abstract: A convenience closure having a removable central panel. A convenience closure is attached to a can end to seal the can. The closure includes a removable central panel; a panel fold with an endless severing line formed in its upper surface; a chuck wall fold which has a nose portion that extends radially inwardly farther than the severing line and overlies the severing line; and a pull tab, attached to the central panel, which has a nose portion that extends to the severing line. The panel fold includes a nose portion that extends to a position adjacent to and under the severing line. To remove the central panel, the pull tab nose is depressed to break the severing line. Then, the pull tab is moved upwardly to complete the breaking of the severing line and remove the central panel. Breaking the severing line forms two sharp raw edges; one lies under the nose of the chuck wall fold and is thus protected. The other raw edge is formed adjacent the nose of the panel wall fold.

Abstract: This invention relates to an apparatus for moving a plurality of two-piece canning jar-type lids in series to a feed mechanism in the form of a magazine which will single-line the caps and maintain them in assembled position. The single-lining mechanism is designed to feed lids into the path of movement of a plurality of containers, also moving in series on their sides with their axes horizontal. The caps or lids are carried at an angle to the path of movement of the finish of the jars such as that the finish of the jars or containers will each individually remove a cap from the supply of caps. The caps are then retained on the finish of the jar and are moved with the jar, in a linear path, with the caps being rotated by frictional engagement and thereby threaded onto the finish of the containers.

Abstract: An improved transfer system is provided for guiding a thermoplastic injection runner from a conveyor into a collection hopper. A thermoplastic runner, which results from the injection molding of plastic parts, such as closures, is moved by a conveyor to a transfer drum which utilizes spikes to direct the runner into the hopper. The closures are separated from the runner as it moves along the conveyor and fall into a collection device at the end of the conveyor. A unique separation grid is positioned above the transfer drum and serves as a guide for the runner as it is directed by the spikes on the transfer drum from the conveyor into the hopper. The separation grid prevents the runner from becoming entangled with the drum or from dropping to the floor. The runner material collected in the hopper can be salvaged for recycling after it has been processed in a grinder.

Abstract: A tamper-proof closure, for a container, which requires removal of a tamper-proof ring before the container may be opened. The closure of the present invention includes a closure body which is threadably engaged with the finish portion of a container. A split tamper-proof ring is attached to the closure body at a plurality of severable locations at the root portion of a plurality of projections formed on the interior of the tamper-proof ring. A severable bridge extends between the opposed free ends of the split tamper-proof ring and connects them. The container has a series of external projections located below the threads of the finish portion. The projections of the tamper-proof ring lock with the projections on the container to prevent removal of the closure body. To remove the closure, the severable bridge is broken and the resulting free end of the tamper-proof ring is used as a pull tab to break the connections between the closure body and the tamper-proof ring.

Abstract: This disclosure relates to a tamper-indicating press-on, pull-off closure for maintaning pressure in a container whereby the closure and container provide a package which may be readily opened by a consumer without the use of tools and without the creation of dangerous sharp edges. This closure includes a cap and a unique cap liner which fits within the cap and is formed integral with a pull ring for removal of the cap from a container. A plurality of severable tamper-indicating webs are formed between the pull ring and the cap liner and sever upon actuation of the ring pull to indicate tampering with the package. The cap incorporates a plurality of scores in its skirt portion which fracture when the pull ring is actuated to thereby release the cap from engagement with the container.

Abstract: A child-resistant liquid seal closure and container combination featuring one or more camming projections on the container neck and one or more locking lugs on the interior surface of the closure which engage the camming projections to prevent rotational removal of the closure from the container. The closure may be removed from the container only by squeezing the closure on opposite sides to force the locking lugs radially outwardly beyond the camming projections to permit rotation of the closure relative to the container. The camming projections on the container neck are of sufficient axial height to prevent rotation of the closure relative to the container both when the closure is fully tightened onto the container and when the closure has been rotated 180.degree. relative to the container, thereby necessitating two separate squeezing actions to remove the closure from the container.
