  • Patent number: 4660746
    Abstract: A liquid dispensing closure cap for application to a flexible wall container. The cap has a delivery tube extending downwardly into the container and upwardly in a pedestal above the cap top. A dosage cap is seated on the top of the cap. A closure lid is hinged to the pedestal for closing over the pedestal and dosage cap. A spout connects the upper end of the delivery tube to deliver liquid to the dosage cup as the container is squeezed. Closure of the lid prevents liquid delivery through the spout. The cup is removable from the cap and container for use, as where mouth wash is dispensed therein.

  • Patent number: 4651882
    Abstract: A system for storing and dispensing a magnetic tape cartridges having a plurality of rows (10) of pivotal storage cells (14) within a frame (2) each cell has a cartridge-discharge end and a rear wall (22) at the opposite end. A support (12) is located beneath the cell and pivot means (16) are located intermediate the ends of the cell to permit the cell to pivot on the support means relative to the horizontal. Means are provided to limit the amount of pivotal movement of the cell relative to the horizontal. The center of gravity of the cell is located closer to the cartridge-discharge end than to the rear wall end. The cartridge-discharge end of the cell normally is inclined to pivot downwardly relative to the horizontal. Means (78) are provided to limit the amount of pivotal movement of the cartridge-discharge end of the cell at substantially a horizontal position. Means (15) are also provided to offer resistance to the downward pivotal movement of the rear wall end of the cell.

  • Patent number: 4630743
    Abstract: A tamper indicating and child resistant package including a screw-type closure for use with a container having a threaded neck. The container is equipped with lock members along the threaded neck and a loading ramp carried on the threaded portion of the neck. The closure has concentric inner and outer skirts depending from the top and a lock tab depending from the outer skirt. A T-shaped tamper indicating means is frangibly attached to the outer skirt and to the inner skirt by means of shear webs. The tamper indicating means has a riding ramp along the inner periphery of the inner skirt to engage the loading ramp during application of the closure to the container to avoid premature removal of the tamper indicating means.

  • Patent number: 4613063
    Abstract: A three piece safety dispensing package for granular or pellet material. A cap is rotatably attached to a container. The cap has dispensing windows that are aligned with openings in the container to a desired degree to control the dispensing rate. The cap can have child resistant locking tabs which engage recesses on the container to maintain the cap locked in a closed position with the cap dispensing windows out of registration with the container openings; opening requires squeezing of the cap to permit rotation to the dispensing position. A tamper indicating tab can be used to prevent rotation until the tab has been broken. The container is filled with product through its open bottom after child resistant lock or tamper indicating tab has been preset as the cap is affixed to the container. The package is finally sealed by introducing a snap-in plug bottom into the open container bottom.

  • Patent number: 4577770
    Abstract: A threaded one piece closure having a tamper indicating ring attached to the lower end of the cap skirt by shear webs which fracture upon the initial opening of the closure leaving the detached ring on the container indicating the initial opening or tampering. The inner surface of the ring has a retaining bead which engages an annular flange on the container which restrains movement of the ring in the opening process. Cooperating drive means on the cap skirt and ring allow initial closure application to the container without fracture of the shear webs.

  • Patent number: 4572388
    Abstract: A threaded one piece closure having a tamper indicating band attached to the lower end of a cap skirt by frangible bridges which fracture upon the initial opening of the closure leaving the detached band on the container indicating the initial opening or tampering. The bottom of the tamper indicating band is formed with a plurality of equally spaced stop segments attached by flexible webs. The tamper indicating band is also formed with a plurality of rectangular windows in line with the stop segments. The flexible webs permit the swinging of the stop segments into an operative position engaged within the windows so that they will coact with a flange or ratchet teeth on the container to provide a means for fracturing the frangible bridges upon unthreading of the cap.

  • Patent number: 4572387
    Abstract: A threaded closure having both a tamper indicating and a non-backoff feature which locks the closure to a container to avoid unwanted loosening. The closure takes the form of a one piece cylindrical cap with an inwardly directed bead at its open end. The cap bead engages a complimentary bead on the neck of the container as the cap is screwed onto the container, and the cap bead snaps over the container bead to form a non-backoff seal. The cap has a tamper indicating band attached to its lower end by frangible webs. The band and container have complimentary stop means which coact to restrain movement of the band when the cap is unthreaded, fracturing the frangible webs giving an indication of tampering or initial opening.

  • Patent number: 4370895
    Abstract: A friction drive wheel, particularly for obtaining a rotary drive for a hydraulic pump or electrical dynamo on a pipeline inspection pig, has a hub with a central hole and keyway for mounting on a axle. Attached to the hub is a rim in which are mounted bundles of bristles in ferrules. The bundle axis is at an acute angle to the radius of the wheel so that the bristles will act as a leading strut. A flange stop may be provided to limit deflection of the bristles.
