A fixture for fluid dispensing bags having lower portions with nozzles. The bags are used with the lower portions folded forwardly and the nozzles pointed downwardly. The nozzles form keys which differ for different groups of the bags. The fixture has a forwardly extending shelf for the lower portions of the bags and in which a hole is formed and an insert is positioned in the hole and has a nozzle hole forming a key hole fitted by the nozzles of only one group of the bags.

Fixtures for fluid dispensing bags

A dispensing device for a bag container a liquid, made of flexible material and forming upper and lower walls through which holes are formed for receiving the device, has a tubular lower part with a top flange which is sealed to the inside of the lower wall and depends through the hole in the lower wall. A tubular upper part has a top flange sealed to the inside of the upper wall and depends through the hole in that wall and is telescoped inside the lower part so as to move up and down in the lower part. The top of the upper part forms a piston such as a collapsible dome extending upwardly through the hole in the upper wall and exposed on the outside of the upper wall and therefore exposed on the outside of the bag. The lower part has a lower end having a self-closing valve and has at least one side port normally open to a space between the flanges and therefore between the bag walls. The lower part has one or more ports normally open to that space and through which liquid contained by the bag can flow into the interior of the device. The upper and lower parts are elastically or spring biased apart and when the piston is pressed the upper part moves down into the lower part until stopped by interengaging of the two flanges, forcing open a self-closing valve in the bottom end of the lower part, so that the liquid in the bag is dispensed.

Dispensing device

A closure for a bottle neck having a tubular upper portion internally having an upstanding post having at least one axially extending passage. The base has an upstanding portion having an external screw thread. The cap has a skirt rotatively surrounding the upper portion, and the skirt has at least one internal protuberance in screw threaded engagement with that screw thread. The cap has a closed top in which a hole is formed and which is closed by the upper end of the post formed by the base, the hole being closed by this upper end when the cap is screwed downwardly and opened when the cap is screwed upwardly.

Speciality closures for bottle necks

A dispensing device for a squeeze bottle has an internal continuously circular vent valve seat. A continuously circular elastic vent valve has one side seating on the seat and an opposite side exposed to the inside of the device. The device has a self-closing dispensing valve which opens upon squeezing the bottle. The device has a lock to prevent unintentional opening of the dispensing valve.

Squeeze bottle self-closing and venting dispensing valve

A wall fixture containing a liquid dispenser, the fixture comprising a bracket having an upstanding plate from the bottom of which a shelf having a nozzle hole extends forwardly and a cover adapted to open and close in front of the plate and shelf, the dispenser comprising a flexible bag having front and back walls containing the liquid and having a main portion with its back wall suspended in front of the plate and a dispensing portion folded forwardly on the shelf so as to form a lower wall, the lower wall having a dispensing valve having a dispensing nozzle extending downwardly through the nozzle hole, and a depressible upper wall above the valve, the valve having an operator between the upper and lower walls and actuated by pressing the upper wall downwardly on the operator; the cover having a pressing arrangement for pressing a bulge in the bag's front wall and extending towards the bag's back wall at a position above the bag's dispensing portion and so as to form a passageway on at least one side of the bulge extending between the main and dispensing portions of the bag when the cover is closed.

Fixture for bag-type liquid dispenser

A device for obtaining, transporting and dispensing a liquid specimen, has a tubular handle having a front portion and front and back ends, a body of liquid absorbent material positioned slidably in the front portion of the handle, and a rod having an end connected to the body and extending through the handle to and through the back end of the handle and having an actuating portion projecting from the back end of the handle for sliding the body forwardly to a projected position where the body is exposed beyond the front end of the handle for contact and absorption by the liquid specimen, and backwardly to a retracted position where the body is returned within the front end portion of the handle and radially enclosed by the handle for transporting the specimen, the body having substantially the same external transverse shape and dimensions as the inside transverse shape and dimensions of the front position of the handle and being substantially free from compression when slid to said retracted position, and the handle having a wall with which the body radially registers when at the retracted position and which wall is radially inwardly flexible under external pressure to radially compress the body and squeeze at least some of the absorbed liquid from the body and dispensing the specimen through the front end of the handle.

Device for obtaining, transporting and using a liquid specimen

A liquid dispenser includes a flexible bag, an enclosing box and an actuator. The bag is formed with two chambers, a supply chamber and a discharge chamber, and a hole through which the actuator moves. The discharge chamber has a discharge member which is acted upon by the actuator to dispense a measured discharge. The bag is suspended in the housing with the discharge chamber folded relative to the supply chamber.

Liquid dispenser

A flexible-bag self-closing metering dispensing valve for a flexible bag containing a fluid product, has a collapsible dome with an entrance for the product, and a valve seat supported by spokes, below which a diaphragm is positioned with a hole having a periphery seated on the valve seat. The spider and seat and the diaphragm are mounted so they cannot be driven out by sudden depression of the collapsible dome.

Flexible-bag self-closing metering dispensing valve

A right-angle spray-nozzle for a squeeze bottle is in the form of a one-piece body and utilizes only one velocity-increasing orifice, thereby avoiding the undesirably slow venting associated with a squeeze bottle having a high velocity jet of liquid that intersects with a second high velocity jet of air.

Right-angle spray nozzle

An elastic squeeze bottle which springs back to shape after collapse by squeezing, contains a viscous product and has a normally closed valve opened by the displaced product and which automatically closes again when the squeezing is terminated. So that air can enter the bottle to replace the displaced product, the valve has a permanently open package proportioned so that the air can be sucked into the bottle, but the passage being too small to permit the viscous product to gravitationally leak from the bottle through the passage.

Viscous product dispensing squeeze bottle having a self-venting

A molded plastic pill box has a lid hinged by a living hinge at one side of its top so the box can be loaded by a pill manufacturer, the lid when swing closed, permanently locking against reopening. The lid has a pill dispensing opening and a child-resistant closure hinged by a living hinge to the other side of the box top and normally closing the dispensing opening. The box forms a package for the pills and which can be sold by the pill manufacturer to a druggist, an adult purchaser being capable of opening the child-resistant closure for dispensing of the packaged pills. The entire box can be a one-piece molding for minimum cost.

Packaging and dispensing pill box

A dispensing spray nozzle particularly adapted for application to a squeeze bottle containing a liquid product, comprises two interfitting parts integrally formed as a single plastic injection molding and including an integral hinge on which, after being injection molded with the hinge holding the two parts side-by-side, the parts can be swung together into interfitting relation so as to produce a finished assembly ready for use.

Dispensing spray nozzle

A dispensing valve, particularly adapted for a squeeze bottle containing a viscous product, has a valve head in the form of a thin flat wafer of small diameter stationarily supported as freely as possible from obstructions, and above it an elastically deflectable diaphragm having a central opening with a periphery that seats on the periphery of the wafer. Internal pressure causes the diaphragm to move slightly from the wafer during a dispensing operation. The diaphragm is dome-shaped and extends upwardly to form an externally ball-like applicator surface.

A right-angle spray nozzle, intended for a squeeze bottle containing a liquid product with air above the product, provides for forming an aerosol spray from an orifice supplied by a swirl chamber having two tangential injection inlets separately fed by air and product respectively when the bottle is squeezed to pressurize the air above the product in the bottle. The spray is ejected in the form of an aerosol at right angles to the axis of the bottle.
