Abstract: A device including an eye cup portion affixed to one end of an extendible tube portion, the other end of the tube portion is adapted for releasably attaching the tube portion to the nozzle of a spray-mist fluid dispenser. In combination, the device and mist dispenser are operable for controlling the delivery of a fluid to the eye. The device functions both as mask to confine the distribution of the spray mist ejected from the nozzle upon the eye and as a jig operable for adjusting the distance between the mist dispenser nozzle and the eye cup portion of the device. In operation, with the device affixed to a spray mist dispenser nozzle and the tube portion unextended (nozzle closest to the eye), a dense mist is delivered to the cornea and surrounding eye tissues when mist is dispensed. When the tube portion is extended, the spray mist dispenser nozzle is further from the eye cup thereby reducing the density of the spray mist impinging on the eye.

Abstract: A liquid dispenser that is suitable for metering pre-measured quantities of liquid from a rigid wall or deformable walled container. The liquid dispenser comprises a nozzle (16) which attaches to the container at one end and attaches to a dispensing chamber (14) at the other end. The dispensing chamber (14) has an opening (24) at its inlet end which juxtaposes with a disk (21) at the discharge end of the nozzle. The nozzle (16) has a central aperture (19) which terminates at the discharge end with inwardly projecting arms (22) which support the disk (21). The seating of the chamber on the end of the nozzle brings the disk (21) into juxtaposition with the opening (24) to control the flow of liquid from the container to the dispensing chamber (14). When the dispensing chamber (14) is fully engaged with the discharge end of the nozzle (16), the opening (24) in the dispensing chamber interlocks with the disk (21) on the nozzle to prevent the liquid from entering the dispensing chamber.

Abstract: An improvement for a tamper evident resealable cap for use on a bottle, the cap having an upstanding spout that is registerable with an opening in the center of the cap and a sealing plug of a smaller diameter positioned thereabove on multiple upstanding legs extending from the spout.

Abstract: A closure for a rigid or deformable container. The contents of the container are protected by a seal. The closure has a bottom part and a cap fixed thereon by a hinge. The lower part is closed by a cover face, through which only a pouring spout extends. A tear-off element is positioned on an underside of the cap in such a way that it extends through the pouring spout as far as the seal located below it. The tear-off element is in active contact with the seal, for example, it is bonded or glued to it.

Such closures are structurally simple in their manufacture as well as in operation and can be attached to various types of containers.

Abstract: A push-to-open, non-resealable cap construction for hand-held dispensers. The cap has a body member with a discharge passage, and a nozzle member carried by the body member and axially shiftable thereon between a raised, sealing position and a lowered, discharge position. There is a discharge orifice in the nozzle member. A valve structure on the members controls communication between the discharge passage and the discharge orifice to regulate product flow. A blocking rib on the nozzle member normally maintains it in the raised, sealing position in the absence of an external axial force, but the rib can be re-positioned by turning the nozzle member, which latter can then be shifted from its raised, sealing position to its lowered, discharge position. A detent structure on the body member and nozzle member thereafter serves to retain the latter in its lowered, discharge position once it has arrived there.

Abstract: A closure cap for a container has a mounting part mounted on the container neck with a closure element over the container opening surrounded by small openings, and a movable part for covering the openings around the closure element when it is moved from an opened to a closed position. The movable part has a passage formed by walls in the shape of a truncated cone defining an external orifice of small openings of a given open area and an internal orifice of a larger open area which is recessed inwardly from the external orifice. The difference in orifice area creates a suction force to suck fluid back into the orifices when the container is returned to the upright position.

Abstract: A pressurizable container has a removable cover. The removable cover has locking elements to maintain the cover sealed to the container when the container is pressurized. The locking device is a piston received in a cylinder, and the cylinder communicates with the interior of the container. When the container is pressurized, the pressure fluid forces the piston and its associated locking bolt into a position such that the bolt passes through a wall of the container and a wall of the removable cover, locking the cover to the container. It is also possible to draw a vacuum on the container when the container is used as a sterilizing device.
