Abstract: A closure having a stopping mechanism whereby a stop lug is positionable between a flexed and unflexed position relative to a spring gap. The stop lug may project from a skirt of the closure top wall. The spring gap is positioned adjacent the stop lug to provide an area for the stop lug to travel when outside forces are applied to the stop lug and subsequently return back to the unflexed position. The stop lug may have a substantially vertical support rib in combination with a plurality of annularly spaced ribs.

Abstract: A closure for a fitment is provided with an outer side wall extending downwardly therefrom and spaced from an inner sealing ring wherein the outer side wall adjacent the top wall is provided with a plurality of spaced inwardly extending ribs, adapted for embedding into a lip at the outlet of a fitment neck.

Abstract: A bottle closure having an outer shell with a frusto-conical configuration and a rib-supported threaded inner shell is described. The frusto-conical configuration of the outer shell allows the user to easily pickup the package and grip the closure and remove it from a bottle. The inner shell is threaded to allow the closure to engagingly mate with threads on a bottle or similar container. The inner shell is supported by ribs which face toward the outer shell. The ribs provide that the inner shell can be unscrewed from a threaded core of a manufacturing mold during production without causing noticeable distortion in the closure.

Abstract: A container finish comprising a helical load carrying member which transmits downward force from the top wall of a closure to the threads of a container to prevent seal failure under stacking load conditions. The helical load carrying member is preferably located on a container neck, parallel to a primary thread. In the alternative the helical load carrying member may be located on a closure finish.

Abstract: A safety closure providing a top wall, an annular outer wall depending downwardly from an outer periphery of the top wall, an annular inner wall depending downwardly from an underside surface of the top wall, and, at least one locking lug integrally molded with the outer wall, whereby downward displacement of the top wall causes outward displacement of the at least one locking lug.

Abstract: Injection-blow molding apparatus in which maximum mold density is obtained by alternate arrangement of circumferentially continuous blow molds and injection molds, with closure of the blow mold being obtained by a shoulder forming sleeve or shoudler forming portion of this blow mold which is moved into abutment with a body forming portion of the blow mold.

Abstract: Injection-blow molding apparatus in which maximum mold density is obtained by alternate arrangement of circumferentially continuous blow molds and injection molds, with axial mold closure being obtained by neck forming and shoulder forming sleeves concentrically located around the cores which are reciprocated into and out of the molds.

Abstract: A two piece safety or child resistant closure for a container in which one piece is a cylindrical cap which is attached to the container by threads or by a flange to snap onto the container. The cap has a dispensing orifice which may be located on the end of a spout through which the contents of the container are dispensed. The second piece of the closure is a cover which is rotatably connected to the cap. When the cover is rotated to its closed position, the dispensing orifice is covered and sealed and the cover is locked against rotation. A rocker arm occupying a portion of the cover is connected to the cover by a torsion hinge and contains the locking mechanism. In order to put the closure into its dispensing position, the rocker arm must be depressed at the same time that the cover is rotated. Rotation of the cover to the dispensing position uncovers the dispensing orifice.

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.

Abstract: A tamper indicating, child resistant closure is provided by a one piece threaded cap having a non-backoff feature. The child resistant component is provided by a squeeze and twist lock having a deflectable tab which cooperates with a radially extending container abutment spaced from the container neck. A radially extending tamper indicating block attached to the cap skirt by a frangible web also aligns with the container abutment and prevents opening unthreading until the block is removed. The non-backoff feature is provided by an inwardly directed flange at the bottom of the cap skirt cooperating with a container bead.

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.

Abstract: A lock arrangement for closures and containers in which the container has a radially extending flange below the threads on the neck of the container and the closure extends below the flange in the closed position of the closure and container. The flange is larger than the inside of the closure which is made of a material which is deformable and has a good memory so that the portion of the closure below the radially extending flange is deformed radially outwardly and returns to its original molded position after the closure has been applied to the container to form an undercut skirt portion affording axial closing pressure between the closure and container and resists unthreading of the closure from the container.

Abstract: A tamper indicating and child resistant package including a closure for use with a container having lock members. The closure has a top with concentric inner and outer skirts depending therefrom. The outer skirt is equipped with locking tabs for engaging the lock member on the container to prevent removal of the closure from the container. The locking tabs are deflectable radially outwardly upon radial inward squeezing of the outer skirt at predetermined diametrically opposed points which are circumferentially spaced from the lock tabs. A frangible, removable taper indicating means is provided to maintain the lock tab in circumferentially spaced relationship to the lock member and the squeeze points in alignment with ramp means on the container to prevent radial inward deflection and opening rotation of the closure until the tamper indicating means is broken away and removed.
