  • Patent number: 3993209
    Abstract: A child-resistant cap and neck finish for a container. The cap has a disc-like top and a depending skirt. The cap skirt and container neck have mating threads, which may be single or multi-start. The cap skirt has a lower, generally annular, or slightly oval locking collar that is connected to the threaded skirt only by flexible webs. The cap skirt and collar are unitary. The collar and the container neck have cooperating child-resistant means which are disengaged by squeezing the collar radially inwardly from opposite sides to bulge it outwardly in the direction normal to the direction of squeezing. The child-resistant elements on the collar are thereby moved out of engagement with those on the container neck and the cap may be turned in a retrograde direction.

  • Patent number: 3974929
    Abstract: A substantially leak-proof and child-resistant combination closure comprising a container and a cap. The container has a neck and the cap has a tubular skirt which fits over the container neck, a disc-like top and resilient annular shoulder portion. The cap skirt and bottle neck have cooperating means for retaining the cap on the container. There is a sealing liner beneath the top of the cap which engages and seals the open end of the container neck. The cap skirt and the container in some embodiments have cooperating locking means which are engaged when the cap is moved down to normal closed position on the bottle neck. The locking means function to render the closure child-resistant. Other embodiments have tamper indicating means. The resilient shoulder portion of the cap flexes to compensate for tolerance variations in the cooperating retaining means on the cap and container neck in order to insure that the cap liner seals the neck of the container.

  • Patent number: 3967745
    Abstract: A child-resistant closure for a liquid container having a threaded neck. The closure comprises an inverted cup-shaped cap which has a shirt and on the inner side of its skirt has a thread that mates with the neck thread. The child-resistant means consists of an outwardly extending ring attached to the end of the skirt by frangible webs. The ring has a gap that is defined by an abutment at one end and a stop at the other end. A tab which permanently is connected to the cap skirt lies in the gap. The cap, ring and tab are unitary and are turned onto the neck to liquid sealing position at which time the ring engages a shoulder formed on the container at or near the base of the neck. The ring is then affixed to the shoulder. The container is opened by flexing the tab upwardly above the level of the abutment on the ring and rotating the cap and tab in a retrograde direction relative to the ring which breaks the frangible webs.

  • Patent number: 3963139
    Abstract: A tamper-indicating closure combination consisting of a container having a circular neck and a twist-on cap therefor. The container neck has external interrupted thread sections with ratchet teeth on their under surfaces. The cap has similar, cooperating internal thread sections on the inner surface of its skirt with ratchet teeth on their upper surfaces. When the cap is turned onto the neck, the sets of ratchet teeth interengage and lock the cap against retrograde rotation. The cap also has a puller which is connected to the cap, a first section thereof being connected by frangible portions and a second section thereof being connected permanently to said cap. In order to remove the cap, the puller is broken away at the first section and then is pulled upwardly and outwardly relative to the container neck to disengage the cooperating sets of ratchet teeth. The cap is replaced by turning it onto the bottle neck for re-engaging the cooperating threads and ratchet teeth.

  • Patent number: 3963070
    Abstract: A multi-blade damper for an exhaust duct through which heated air flows after passage through heat exchange coils carrying a hot, liquid heat exchange medium which is subject to solidification if cooled too greatly, for example, sodium. When the heat exchange medium is very hot, air is forced through the duct by high volume fans and the damper blades are opened widely. When the source of heat to the heat exchange medium is shut down, however, the flow of the heat exchange medium and its temperature are greatly reduced. Even if the fans are shut off at this point, the natural draft of air through the duct may so cool the coils of the heat exchanger that the medium will freeze in the coils. Under these conditions, some of the damper blades are closed to majorly reduce the air flow. However, during the transition from hot operating conditions to stand-by conditions and during stand-by periods, the heat exchange medium must be kept hot enough to prevent solidification.
