  • Patent number: 5431306
    Abstract: A plastic container for pourable liquids such as detergents has a drain back feature and has an internal thread for receiving an externally threaded cap which also serves as a measuring cup for the liquid. The container is formed in two pieces, a container body and a separately formed pour spout component which is assembled to the container finish preferably by ultrasonic welding. In preferred embodiments a lip of the pour spout component is pressed and welded down onto an annular top surface of the container finish, or down into an annular recess on the container finish. The ultrasonic welding operation is accompanied by motion and pressure, simultaneously deforming and welding the top edge of the pour spout component wall down onto the container finish, so that the connection forms a liquid tight seal.

  • Patent number: 5333759
    Abstract: The present invention is a beverage dispensing apparatus which allows the dispensing of beverages from a modular dispensing tower which may be positioned remote from both the product and the cooling unit. The modular dispensing tower is connected to the cooling unit through an insulated trunk line which allows its positioning up to twenty five feet away from the cooling unit. Additionally, the modular dispensing tower comprises an insulated manifold which operates to significantly decrease the temperature of the dispensed "casual" drink. The manifold houses a plurality of product conduits which are positioned against a carbonated water conduit which works in a recirculation system to greatly reduce the temperature of the dispensed "casual" drink. Furthermore, the modular dispensing tower may reside on the countertop or may be mounted onto the edge of the countertop in order to save countertop space.

  • Patent number: 5292039
    Abstract: A bottle for storing a liquid and dispensing measured quantities thereof. The bottle has a large storage chamber and a small measuring chamber, each chamber including its own threaded, removable cap. The measuring chamber is adjacent and partially above the storage chamber, an opening extending and communicating therebetween. The opening opens to the top of the storage chamber and to the middle of the measuring chamber. A conduit controlled by a manually operated valve extends and communicates between the lowermost portion of the storage chamber and the lowermost portion of the measuring chamber. In a preferred embodiment, the conduit forms a loop with the remainder of the bottle, thus serving as a handle. In this embodiment, the manual valve is located such that it is operated by the hand grasping the handle. In use, the bottle is first inverted, and the valve held open, so that stored liquid fills the measuring chamber.

  • Patent number: 5224526
    Abstract: Bottles, cans or other types of containers are filled with accurately metered quantities of a liquid by employing a number of discrete filling units which orbit about a vertical axis and are provided with metering chambers receiving liquid from a main source of supply. The metering chambers are overfilled with liquid, and the excess is collected and returned to the main source. The filling units and certain other parts (such as an annular vessel of the main source) of the apparatus can be of modular design to facilitate storage and transport of modules which are assembled into a container filling apparatus at the filling plant. The method and apparatus can be utilized with advantage for the admission of metered quantities of carbonated and/or pulp-containing beverages into bottles or cans.

  • Patent number: 5180080
    Abstract: To control the dispensing of granular dry matter, the upper face of a flange extending from the perforations in the top of a dispenser for granular dry matter is positioned substantially in a horizontal plane and the dispenser is shaken. The granular dry matter is dispensed from the container through a channel in the flange containing the perforations, over the upper face of the flange and observed by the user. The amount of granular dry matter on the upper face may be added to by further shaking the dispenser while briefly tilting it slightly so that the output end of the upper face is below its feed end. The amount of granular dry matter on the upper face may be reduced by shaking the dispenser while briefly tilting it so that the output end of its upper face is slightly above its feed end so that the granular dry matter falls into the channel and back into the container.

  • Patent number: 5143261
    Abstract: A container for successively dispensing substantially uniform volumes of a plurality of liquid ingredients such that the liquids are simultaneously dispensed in a desired proportion to form a mixture. The container has a plurality of separate compartments; each compartment being adapted to house a different liquid ingredient. Each compartment has a tubular metering device located therein. The metering device dispenses a previously metered volume and meters a second volume by controlling the venting of air within the compartment each time the container is tilted and uprighted as in a normal dispensing operation. A continuous lip surrounds the dispensing opening of each metering device. The continuous lip prevents a liquid ingredient from entering the dispensing opening of another liquid ingredient compartment and contaminating that compartment. In addition, a flip top cap is attached to the upper end wall. In the closed position the cap seals the dispensing openings of each metering device.

  • Patent number: 4793515
    Abstract: A soda system for soft drink dispensers which includes an auxiliary tank adapted for maintaining a reservoir of cold soda for immediate dispensing, which soda is also recarbonated in the auxiliary tank. A recirculating pump passes soda from a carbonation unit sequentially to various dispensing stations for a return to the circulating pump. Interposed in the soda path is an auxiliary tank from which the dispensing of soda is actually made. The auxiliary tank communicates with a source of pressurized carbon dioxide to maintain a head of that gas therein for purposes of recarbonating the soda while providing the pressure head for dispensing the soda. Shunt lines are provided in communication with soda dispensing lines to assure that even the soda within the dispensing lines is recirculated and refreshed.

  • Patent number: 4784295
    Abstract: An enclosed slurry dispensing system employs a sealed pressurized reservoir for supplying slurry through a bypass chamber to a dispensing nozzle. Excess slurry is bypassed through the bypass chamber to an intermediate chamber. Slurry is allowed to return to the reservoir through a normally-closed check valve, closed by the higher pressure of the reservoir. The system is purged by opening the reservoir to the atmosphere, creating a sub-atmospheric pressure in the bypass chamber. Air is admitted through the nozzle to purge the nozzle of slurry. At the same time, the check valve opens and excess slurry returns to the reservoir from the intermediate chamber.

  • Patent number: 4474312
    Abstract: This invention relates to a dispensing unit for dispensing preselected quantities of liquid from a container, such as a squeeze bottle. The dispensing unit includes an outer cup member and an inner cup member, with the inner cup member having radial openings therethrough which are circumferentially spaced and at selected heights so as to determine the level of liquid within the inner cup member. The outer cup member is provided with an axial flow passage which may either be sealed by the inner cup member or which may have one of the openings in the inner cup member aligned therewith. The liquid dispensed into the inner cup member, if the inner cup member is accidentally overfilled, will seek the pre-set level so that the desired measured amount of the liquid which is to be dispensed will be retained within the inner cup member.
