Abstract: This is provided a beverage dispenser for dispensing carbonated beverages from bottled beverages. The dispenser comprises a bottle holder for holding bottles in an iverted position and a dispensing valve which screws onto each bottle neck in place of its standard cap closure. The dispensing valve has two passages: a vent passage to decompress the beverage in the bottle just before its discharging of the beverage and the second a discharging passage for the discharging of beverage therefrom. The passages are closed by the insertion of plungers into each of the passages far enough to seal the passages. The plungers are attached to a slide so as to simultaneously move the plungers together. The outside edges of the passages are offset so as to permit, during the opening stroke, the vent passage to open first. The slide and its attached plungers are pushed to close or pulled to open the passages by a hand operated lever which rotates around a fulcrum point under finger pressure.

Abstract: Products having a viscous or pasty consistency, or those dispensed as foams from a container (1) provided with a pushbutton (13) the actuation of which causes the ejection of a dose of product, are never, in practice, completely evacuated from the ejection conduit (14) made in a movable portion (9) bearing the pushbutton (13) and adapted to the outlet of the container (1). Hence they often threaten to escape from this conduit (14) and soil the container (1). To overcome this disadvantage, the invention proposes that the conduit (14) discharge into a chamber (40) defined by a fixed portion (10) attached to the container (1) and with the movable portion (9) comprising a dispensing cap (8); the chamber (40) opens to the outside via an opening (38), and the movable portion (9) includes a needle (27) capable of closing this opening (38) in the position of repose of the pushbutton (13) and of freeing it upon actuation of the pushbutton.

Abstract: Apparatus for controlling the discharge of fluent, particulate plastic material from a supply to a blending hopper comprises a delivery tube having a discharge orifice at its lower end that may be closed by a circular valve which seats against the delivery tube to close and seal the orifice. The valve is movable from its closed position to a fully open position in which a relatively large clearance exists between the discharge orifice and a body of material supported at its angle of repose on the valve. Material thus is able to cascade through the clearance to a receiving hopper whose weight is monitored by one or more load cells coupled to a microprocessor. When the weight of the receiving hopper increases to a selected value due to the delivery of material thereto, the valve is moved from its fully open position to a partially open position in which the aforementioned clearance is reduced substantially, thereby materially slowing the rate of discharge of material from the supply.

A variety of irritant sprays particularly adapted to various conditions are also described.

Abstract: A fluid dispensing valve mechanism including a valve body member having an annular seat portion which is contacted by the bushing portion of the shaft-bushing member to effect a seal. The shaft is interposed between the bushing and a contact point on a tower assembly, the latter held in fixed relationship to the valve body. The shaft, at least, is made from elastomeric material; and it is bowed off the axis between the center of the annular seat portion and the contact point on the tower assembly, when in position. This results in a positive seal between the bushing member and the annular seat. When the bushing member is displaced axially to dispense the fluid, the shaft member bows even further. The hysteresis effect inherent in the elastomeric shaft returns the bushing member to its contact position with the annular seat.

Abstract: A self-sealing container closure includes a rotatable cap mounted over the mouth of an oval squeezable container. The cap has an outlet opening defined by a valve seat. The outlet opening is sealed by a valve element forced against the valve seat by a valve spring and a pair of actuating arms. An upper end of each actuating arm is non-rotatably coupled to the cap while the lower end is connected to the valve spring. When the cap is rotated to align the actuating arms with the minimum width of the container, squeezing the sides of the container presses on the actuating arms to further deflect the valve spring. This forces the valve element away from the valve seat to open the container. Rotating the cap, to align the arms with the maximum width of the container, places the container in a non-operational mode. Also disclosed is a piston and cylinder arrangement coupled to the actuating arms for dispensing a measured amount of liquid from the container.
