Abstract: A valving gasket is disclosed for a squeeze bottle sprayer. The gasket includes upper and lower gaskets, each having a vent hole and a flap valve. The vent hole on the upper gasket cooperates with the flap valve on the lower gasket, and the vent hole on the lower gasket cooperates with the flap valve on the upper gasket. The result is that two valved vent paths are created--one for incoming air and one for outgoing air. The incoming air is used to fill the dispenser after squeezing, to equalize pressure in the bottle. The outgoing air is directed through a vent path to a spray chamber and is intermingled with outgoing liquid to create a fine mist spray pattern. The outgoing air vent is small enough to allow escaping air but to prevent exhausting of all pressure during squeezing. The outgoing air flap valve prevents leakage through the outgoing air hole when the bottle is inverted. The upper gasket may also have a flap valve for the outgoing liquid.

Abstract: A fluid dispensing system for delivering sterile preservative free solution is disclosed. The system uses double self-sealing valves mounted in series inside a tip compartment which fits on the outlet of a multiple dosage squeeze container to prevent undesirable retrograde flow of the dispensed liquid back into the bottle during the decompression cycle. The valves used are positive acting, normally closed duckbill valves which open to express solution from the container when squeezing pressure is applied to the bottle and which automatically close when the pressure is released. A hydrophobic filter is provided to sterilize the replacement air which enters the container upon release of the squeezing pressure.

Abstract: A method and apparatus for generating a flavoring syrup within a soft drink dispenser are disclosed. Syrup generation tanks receive sugar and water and combine the two to create a saturated solution constituting a sweetening syrup. The sweetening syrup is passed to a dispensing head. A flavoring agent is also presented at the dispensing head, as is a supply of soda or carbonated water. Dispensing of the sweetening syrup, flavoring agent, and soda is controlled by valves associated with each of the ingredients. The brix of the sweetening syrup is determined as a function of the temperature of the sweetening syrup, such brix being determinative of the amount of sweetening syrup dispensed to assure a proper brix level of the resulting drink.

Abstract: An assembly for mixing and dispensing preparations such as dental cements includes a capsule and a lever actuated dispensing device. The capsule is received in a first orientation of the dispensing device for initial movement of a piston of the capsule to combine two components in a mixing chamber of the capsule. The capsule is received in a second orientation when dispensing of the components is desired. The capsule includes flanges engageable with one or more retention members of the dispensing device, and the flanges are positioned to substantially utilize the mechanical advantage provided by the dispensing device regardless of whether the capsule is in the first orientation or in the second orientation. The flanges are also arranged to substantially prohibit bursting of the capsule when the components are discharged from the mixing chamber, and essentially preclude dispensing of the components when the capsule is in the first orientation.

Abstract: A machine for dispensing powder products into suitable receptacles comprises a rotating container in which is defined a withdrawal zone, a dispensing unit, and a fixed device which levels the produce in the container. The device includes a member located upstream of the withdrawal zone and having a first portion which levels the product into a layer and a second portion which defines a channel which directs the product accumulated on this first portion in excess of the layer, towards a part of the container downstream of the withdrawal zone; and a member positioned downstream of the withdrawal zone, along which the excess product slides. The latter member defines with a central part of the container, a passage which directs the excess product towards a part of the container upstream of the fixed device.

Abstract: A separator pan (10) is set into a rearwardly leaning position (FIG. 4 ). A lower portion of the pan sidewall (28) slopes downwardly as it extends outwardly from the pan bottom (12). A spiral rib (32), inside of the pan (10) slopes upwardly as it extends axially outwardly from the interior of the pan (10). Pan (10) is rotated in a direction causing the spiral rib (32) to coil inwardly. Large particles of gold ore, introduced into the pan (10), gravitate out from the pan, owing to the sloping nature of the lower portion of pan sidewall (28). Smaller particles, including small particles of gold, are trapped between spiral rib (32) and sidewall (28) and bottom wall (12) of pan (10). As the pan (10) rotates, these small particles are moved inwardly and into a hub cup (14).

Abstract: A syringe-dispensing system includes a housing containing at least one sealed bag of a fluid reactive compound and a nozzle in fluid communication with the housing for providing an outlet from the housing for the compound. A shaft disposed within the housing and attached to a handle for moving the shaft longitudinally within the housing is provided, along with apparatus for piercing the bag upon movement of the shaft in one direction. A piston enables forcing of the compound out of the housing through the nozzle upon movement of the shaft in an opposite direction.

Abstract: A dispensing head for a squeeze dispenser is disclosed. The dispensing head includes a mixing chamber where pressurized air and pressurized fluid are mixed to produce a fine spray. A valved gasketing arrangement is used to control the flow of air into the container and out of the dispensing head, as well as to control flow of liquid to the dispensing head and to prevent leakage when the dispenser is inverted. The dispensing head also includes a liquid flow control device. This device uses a spring-biased piston to shut off the liquid flow path when the liquid is not pressurized. The piston acts to seal off the liquid from the atmosphere, thus preventing drying or contamination of the liquid product. A collapsible bag is also disclosed for isolating the liquid in the container from the air in the container.

Modular units such as a stirrer, a weigher or feeder or the like are vertically aligned, vertically below the hopper. At least one, preferably each modular unit is mounted on a respective swivel arm. The swivel arm is journalled to the upright post whereby the modular unit may be tilted into an operative position below the hopper or into an out position for easy access to and exchange of the modular units.

Abstract: A tool for squeezing out a high-viscosity liquid from a flexible plastic tube container includes a spool having a slot in which the bottom of the tube container is received and locked, and a container holder having a pair of opposed bearing portions frictionally and rotatably supporting thereon a body of the spool, and a pair of opposed engagement portions engageable with a body of the tube container as the tube container is wound on the spool body from the bottom thereof. When a rotational force or torque on the spool is released, the spool is urged to rotate in the reverse direction by a resilient force stored in a portion of the flexible plastic tube container wound on the spool body. However, partly due to a friction acting between the spool body and the bearing portions, and partly due to the engagement between one of the engagement portions and the tube container, the spool is held immovable relative to the container holder against the resilient force of the tube container.

Abstract: The improved dispensing tool has linkage that includes a spring connected between a power ratchet and a wall restraining the material cartridge against plunger movement through the cartridge for discharging material, thereby allowing resilent independent plunger movement within the limits of spaced stops. When subjected to only static force conditions, the spring bottoms the linkage solid against one of the stops, to provide in-unison forward indexing of the plunger and ratchet drive rod. In the event plunger displacement occurs that is less than the expected in-unison indexing, the one linkage stop is gapped to subject the spring to additional dynamic force conditions that biases the plunger resiliently and continuously in the forward direction toward the restraining wall, up to maximum dynamic force conditions that bottoms the linkage solid against the other stop. The dynamic spring forces move the plunger forwardly within the cartridge for discharging the contained material.

Abstract: A container having a threaded tubular neck out through which a contained liquid can be poured is provided with a screwed on outlet funnel. The outlet funnel houses a liquid-buoyant, invertible stopper, which is heavier towards an end provided with a sealing-preventing feature, than towards a diametrically opposite end provided with a sealing-providing feature. The container itself may be of conventional construction. The funnel possibly telescopes for selectively locking the stopper in place in either an orientation in which it seals to prevent liquid from entering the funnel from the container, or to prevent liquid from pouring from the funnel.

Abstract: A caulk gun has a cartridge-carrying body with a fixed handle and a pivoting handle depending therefrom, the pivoting handle being coupled to a plunger for axial movement thereof to dispense material from the cartridge in response to movement of the pivoting handle toward the fixed handle. The pivoting handle has a proximal end portion which diverges from the fixed handle to an index finger engaging portion and a distal end portion which is curved toward the fixed handle in the normal rest configuration of the gun, such that the pivoting handle, at both its distal end portion and its index finger engaging portion is spaced from the fixed handle generally the same distance. The fixed handle has a widened portion intermediate the ends thereof.
