Abstract: A container-closure assembly comprises a container molded of relatively soft plastic and a closure cap molded of relatively hard plastic and having a top wall and a continuous side wall. Threads are formed on both the finish of the container and inward on the side wall of the cap. The threads on the cap comprise three threaded segments spaced about the inner circumference of the side wall. The segments include an inward upwardly sloping rib, the upper surface of which is formed with a plurality of wedge-shaped teeth. In use, the closure is screwed on to the top of the container finish and the teeth dig onto the underside of the threads on the finish causing the instantaneous elastic deformation of the plastic of the finish to anchor the cap against removal.

Abstract: The directional control valve housing in a squeeze bag resuscitator includes a duck-bill element which permits inhaling from the bag as the duck-bill opens, and spontaneous exhaling as the periphery of duck-bill is pushed away from its seat. An adjustable spring urges the periphery against its seat with force established by the PEEP setting. The housing is in two screwed-together parts and the PEEP setting is effected by screwing the parts inward or outward.

Abstract: In this assembly the spout attachment has at the top of its vertical wall a flat annular wiper flange having an upstanding sealing bead. The flange is clamped between the top of the mouth of the bottle and the undersurface of the closure so that the bead seals against the closure and no liner is necessary in the closure. To keep the attachment from uncontrolled rotation as the closure is screwed on and off, the vertical wall of the attachment is provided with a pair of horizontally aligned closely spaced lugs which straddle an inward protrusion in the mouth of the bottle.

Abstract: This structure includes a resilient collar having a central boss with an opening which receives the discharge apparatus, such as a pump or valve. The collar fits over the flange of the container and has an outward protrusion in the form of fingers. A sleeve is sized to slide down over the side of the collar where it surrounds the flange and cams inwardly the protrusion to hold the collar on the container. The improvement relates to a re-entrant portion at the upper end of the sleeve which extends downward in an inner tube terminating at its lower end in a short inward annular flange which grips the sides of a central boss on the collar to keep the sleeve from being vertically displaced.

Abstract: Closure assembly includes a lid carrier or base having a hinged lid. The top wall of the lid carrier has a sealing means surrounded by a downward alignment sleeve. The assembly is especially useful with high-speed automatic container-capping machinery, because the sleeve cooperates with the cylindrical upright neck or spout on a container to see that the closure assembly is not cocked prior to sealing and that the top of the spout makes square contact with the sealing means to assure a good seal. The sleeve is interrupted on the opposite side of the carrier from the hinge so that it does not interfere with action of a latch depending from the lid. The spout itself forms a stop for the latch so that it will not be overextended and break when it is pressed in unlatching.

Abstract: A lipstick case includes a casing rotatably attached to the base, and driving means involving a "floating" sleeve which is spirally slotted and engaged both by lugs on the pomade support stem and on the base. The casing and base attach together in snap installation.

Abstract: This invention relates to a nozzle for dispensing and aerating liquids. The nozzle provides for the formation of a substantially hollow conical vortex which aspirates air into the nozzle. The vortex is formed within a first chamber so that the base of the vortex impinges upon the chamber walls. This impingement results in the formation of a turbulent film which, when brought in contact with the aspirated air, results in aeration of the liquid forming the film. A foam-like characteristic is given the liquid by the entrapment of the air as the liquid is dispensed. The aspirated air enters through the downstream end of the nozzle but is directed both towards the front of the vortex and towards the rear of the vortex.

Abstract: This invention relates to a nozzle which is capable of selectively dispensing a liquid product as a foam or a spray. A swirl chamber delivers a vortical sheet from the nozzle orifice. The nozzle features a movable chamber which can be moved to a point where it offers no interference with the vortical sheet and thus the spray mode of delivery is effected. The chamber can be moved to a point where interference with the vortical sheet is effected and the formation of a turbulent film is realized. Gas passageways are provided to achieve aeration of the turbulent film and the resultant dispensing of the liquid as a foam.

Abstract: This invention relates to a nozzle for dispensing and aerating liquids. The nozzle provides for the formation of a substantially hollow conical vortex which aspirates air into its interior. The vortex is formed within a chamber so that the base of the vortex impinges upon the chamber walls. This impingment results in the formation of a turbulent film which, when brought in contact with the aspirated air, results in aeration of the liquid forming the film. A foam like characteristic is given the liquid by the entrapment of the air as the liquid is dispensed.
