Abstract: A blender hopper has a contiguous annular side wall with a larger upper portion, and a smaller lower portion. The upper portion is in the form of a square and the lower portion is in the form of an octagon and a bottom wall adjoins the lower portion. Four narrower triangular side walls extend upwardly and outwardly from the diagonal sides of the bottom wall and adjoin the four corners of the upper portion, respectively, and four wider truncated wedge-shaped walls extend upwardly and outwardly from the four orthogonal sides of the bottom wall with their wider ends adjoining the four sides of the upper portion, respectively, and inwardly protruding longitudinal rib is formed in each of the wider truncated wedge-shaped walls. A tubular dispensing conduit is secured in an aperture in one of the wider walls and a dispensing valve is connected to its outer end.

Abstract: A semi-frozen slush beverage is contained in a thermally insulated vessel which is removably supported on a base unit containing a gas pressurizing mechanism and a motor connected to an electrical source. The gas pressurizing mechanism is controlled by a pressure sensor to maintain pressure on the beverage inside the vessel and an agitator contained within the vessel is releasably connected to the motor shaft when the vessel is supported on the base unit and is operated to swirl the beverage to prevent the semi-frozen slush beverage from separating. A slush delivery valve on the vessel side wall has an outlet end to which a dispensing nozzle or a flexible insulated hose having a dispensing nozzle at its outer end may be releasably connected for dispensing the beverage. The power source may be a battery disposed in the base unit and the base unit may be provided with a battery recharging receptical and associated circuitry.

Abstract: A backpack carried on the back of a vendor for transporting and dispensing packaged goods, such as food products or other merchandise. The backpack has a back wall, front wall, opposed side walls, a top closure, and a bottom wall defining a generally rectangular storage compartment. The backpack has at least one access opening at a lower end which is accessible to the hand of the vendor wearing the backpack. A plurality of packaged goods are supported in a vertically descendable disposition by a support member or receptacle installed in the storage compartment which has a lower portion disposed adjacent to the access opening and is configured to support the lowermost one of the packaged goods adjacent to the access opening such that it can be manually removed by the vendor while the backpack is being worn.

Abstract: A portable beverage dispenser system particularly suited for dispensing semi-frozen slush beverages is housed within a back pack and transported on the back of a vendor. The slush beverage is contained in an insulated vessel having a sealed closure lid, a gas supply valve connected with a pressurized gas tank to maintain pressurization of the beverage, a slush delivery conduit with an insulated dispensing hose releasably connected to the conduit, and an agitator contained within the vessel which is rotated by a motor on the vessel exterior. The motor is selectively operated by a battery pack carried by the back pack to swirl the slush beverage adjacent the lower end of the delivery conduit and to prevent the semi-frozen slush beverage from solidifying as it is being discharged. The vessel is surrounded by a thermally insulating jacket which prevents the formation of a thin layer of ice on its exterior due to the temperature of the semi-frozen slush beverage contained therein.

Abstract: A backpack carried on the back of a vendor for transporting and dispensing individual cans or bottles of a beverage, has at least one thermally insulated generally rectangular storage compartment configured to hold a plurality of cans or bottles of a beverage in vertical descendable disposition, a closable lid at the top end of the backpack, and at least one access opening disposed at a lower end of the backpack in a position accessible to the hand of the person wearing the backpack.

Abstract: A portable beverage dispenser system is housed within a rigid back pack transported on the back of a vendor. A beverage dispensing container, dispensing hose, and a pressurized gas container is housed within the back pack. The beverage dispensing container has a rigid wall surrounded by a flexible thermally insulating and cushioning jacket and an access opening at the top end of the dispensing container receives a removable flexible liner. A releasably locked closure lid is removably mounted within the access opening and has a gas fill valve and liquid fill and dispensing valve thereon with passages extending through the closure. The flexible liner is inserted into and withdrawn from the dispensing container in a collapsed condition and substantially conforms to the shape of the interior of the container in an installed liquid filled condition. The liner has an open end releasably engaged on the lid closure and forms a fluid pressure sealed envelope for containing the liquid beverage and the pressurized gas.

Abstract: The liquid storing volume of rigid dispenser tank is varied by inflation of a gas impermeable bladder with pressurized air to maintain the liquid beverage under pressure. The bladder is inserted or withdrawn from the tank through a releasably sealed opening. The dispenser includes a locked closure positioned in underlying relation to a flexible jacket for the tank.
