  • Patent number: 4978032
    Abstract: An apparatus is described for dispensing the bottom cup from a selected stack of cups utilizing a rotatable carriage for supporting a plurality of stacks of cups arranged along the rotary path of the carriage. As the carriage rotates a stack is selected from which a cup is to be dispensed a sensor determines when the selected stack reaches a predetermined position along the rotary path of the stacks. There are separators for separating the bottom cup from the respective stack and a solenoid operated ramp for movement into the rotary path of the separating means to separate the bottom cup from the selected stack. The solenoid operated ramp is operated by a signal from the sensing means.

  • Patent number: 4976381
    Abstract: A container of draft beer is substantially filled with beer having a volume of dissolved carbon dioxide greater than 2.6 and not more than 3.1 times the volume of beer. The beer is packaged in a plastic container that is slightly permeable to carbon dioxide, but retains a satisfactory dissolved carbon dioxide content even after a normal shelf life. Beer is dispensed by gravity, without use of external pressure source, after release of head space pressure. Moreover, when the container contents are partially dispensed by the consumer and then maintained at appropriate low temperature for several days, the remaining beer still retains a satisfactory volume of dissolved carbon dioxide. A spigot on the container employs a barrell valve closure member that seals the pressurized container and is movable to a pressure relase position in which pressurized gas within the container is slowly released without forcibly projecting container contents.

  • Patent number: 4974756
    Abstract: A container and cap assembly includes a double barrel dispensing container having two side-by-side outlets, and a cap with two side-by-side closure portions for simultaneously closing both outlets when the cap is connected to the container. The cap includes two protruding orienting sections for orienting the cap relative to the container as the cap is connected to the container. The orienting sections insure that each closure portion comes into contact with the same outlet each time the cap is coupled to the container so that small quantities, if any, of materials flowing through one outlet and deposited on one closure portion of the cap cannot cross-contaminate materials in the remaining barrel after the cap is removed and then re-connected to the container after a dispensing operation.

  • Patent number: 4972977
    Abstract: The present invention comprises a spray bottle in which the pressure resulting from the gripping force applied by the user is amplified and this increased pressure used in generating a spray such as an aerosol or fluid stream. In its preferred embodiment, the invention includes a high pressure chamber and a corresponding piston which is operative for driving fluid out of this chamber at high pressure through a spray nozzle and a low pressure chamber and a corresponding piston which is acted upon the hydraulic pressure within the bottle resulting from the gripping force. The low pressure chamber and piston are of larger size than the high pressure chamber and piston. The pistons are rigidly connected so that the force created by the pressure acting on the piston in the low pressure chamber is transmitted to the piston in the high pressure chamber where it is applied over a more limited area thereby generating greater hydraulic pressure for use in forming the spray.

  • Patent number: 4936494
    Abstract: A shake-and-spoon cap for condiment containers and the like is formed of a one-piece injection-molded body. The cap provides a cylindrical skirt having inwardly projecting thread forms for mating with the male threads of a condiment container or the like. Two flaps are provided for selectively opening and closing a spoon opening and a plurality of shaker openings. The cap is structured so that the exposed end of the cap is a circular, planar surface when the flaps are closed. A sealing land inwardly spaced and concentric with the skirt is positioned to seal with the mouth of a container. The interior and exterior surfaces of the end wall are contoured so that substantially the entire cap has a uniform wall thickness. Peripherally spaced, radially extending ribs stiffen the cap between the land and the skirt to resist deflection and to ensure that the flap latching structure functions reliably.
