Abstract: A conveyor apparatus for receiving and transporting cylindrical stock or articles past work stations includes a plurality of rollers disposed along spaced-apart parallel axes. The rollers are driven through one-way or overrunning clutches and rotate cylindrical stock disposed between adjacent pairs of rollers. At a work station, a moving member such as a belt engages the stock and rotates it at a speed higher than the speed imparted to it by the rollers. The overrunning clutches release the conveyor rollers and rotate with the stock at a correspondingly higher speed. The constant, non-slipping contact between the rollers and stock minimizes such difficulties as scoring of the stock and significantly improves product quality and appearance.

Abstract: A tamper indicating package comprising a container having a neck finish with a large opening and threads on the exterior thereof, and an annular bead spaced axially from the threads and away from the open end of the container and a plastic closure having a top wall and a peripheral skirt formed with interrupted threads adapted to engage the threads on the container and an integral tamper indicating band on the periphery of the skirt connected thereto by an internal groove which defines a weakened line and having an interrupted radially extending bead adapted to engage the bead on the container. The bead on the tamper indicating band is interrupted along the same axial plane as the threads on the skirt so that the tamper indicating band is without a bead in substantially the same areas as the portions of the skirt are without threads.

A closure of plastic material, such that it will flex in thin cross section, is provided with an annular wall, a radial wall engaging the free edge of the peripheral lip of the container, and a transverse wall defining a convex surface facing inwardly of the container. The closure has a downwardly and outwardly inclined integral annular sealing surface at the juncture of the axial wall and transverse wall which engages the sealing surface of said container and places the axial wall under tension.

Abstract: A crown closure and container comprising a glass container having a crown finish without threads, a closure comprising a rigid plastic outer shell and an inner cup-shaped liner. The outer shell comprises a top panel and a peripheral skirt. The liner is made of soft resilient plastic material and comprises a top wall and a peripheral wall. Interengaging cam surfaces are provided between the inner surface of the skirt of the shell and the outer surface of the peripheral wall of the liner such that when the closure is applied to the crown finish by an axial motion of the closure relative to the container, the liner if forced into the shell and the upper portion of the liner engages the crown finish of the container. The peripheral skirt of the outer shell is formed with threads so that the upper portion of the liner is forced into the threads and will allow for sufficient interference with the liner and finish to permit removal of the closure by rotation of the shell in relation to the liner.

Abstract: There is provided a method of continuously producing a highly oriented heat shrinkable single layer of amorphous styrene foam or a composite of a thermoplastic film and an amorphous polystyrene foam to form a heat shrinkable two-layer sheet that is easily stored without substantial shrinkage at ambient temperature, the outstanding single-layer sheet or two-layer sheet being adapted for heat shrinking rapidly to form a label around a container or a cup.

Abstract: The invention relates to a limited torque applicating mechanism for applying caps to the threaded necks of containers. Torque is transmitted to a conventional cap applicating head from a rotating power shaft by positioning a ring of permanent magnets on either the driven or driving element and disposing a ring of high magnetic permeability material concentrically adjacent on the other of the driven or driving elements so that the torque transmitted between the driving and driven elements is limited by the magnetic attraction between the ring of permanent magnets and the ring of high permeability magnetic material. The apparatus further incorporates a mechanism for adjusting the relative axial position of the ring of permanent magnets with respect to the ring of high magnetic permeability material to permit selective adjustment of the amount of torque transmitted.

Abstract: A child resistant package comprising an open-mouth container having a plurality of circumferentially spaced projections extending radially outwardly adjacent the open end thereof, each projection defines a notch facing downwardly, and a closure having a top panel and an annular skirt depending from the periphery of the top panel, and a plurality of radially inwardly extending and circumferentially spaced locking lugs on the inner surface of the skirt. The locking lugs are adapted to engage the notches in the projections on the container. A tamper-indicating member comprises an annular ring having portions extending between the lower edge of the skirt of the closure and a portion of the container and operable to normally limit axial movement of the closure. The ring offers a visual indication that the contents have not been tampered with and the ring must be removed before the closure can be removed. The container includes a specially designed inclined surface provided with dual slopes.

Abstract: A method and apparatus for inspecting glass tubes for fire checks and other defects is disclosed. Each tube is positioned on transport equipment and moved through an inspection area as it is rotated about its longitudinal axis by a spinner mechanism. A broad source of diffused light illuminates each tube in the inspection area. A camera is positioned above the moving line of tubes and includes an array of photosensitive diodes arranged parallel to the longitudinal axes of the tubes. A check in a tube will reflect a higher intensity light to the camera than a non-defective portion of the tube. By averaging the signals from the first few diodes for each longitudinal scan of the camera, a reference voltage level can be electronically determined for each scan. Any signal generated by a diode element of the camera which is greater than the sum of the reference signal and a predetermined signal indicates the presence of a defect in the tube.
