  • Patent number: 6772915
    Abstract: Such dispensers must be easy to grasp or operate by a user, e.g. a user suffering from rheumatoid arthritis and whose capacity to manipulate objects is under certain circumstances limited. In addition, the dispenser must have a simple, inexpensive construction from a minimum number of components. The dispenser is used for the discharge of media, particularly fluids, e.g. a liquid, which preferably contain a pharmaceutical substance, as described in exemplified manner hereinbefore. In the case of the dispenser, the medium is discharged in at least two proportioned partial charges by actuating an actuating means. As a result of the actuation of the actuating means, a relative movement is produced between the actuating means and a housing having a dispenser discharge opening. According to the invention an elastically deformable material bridge is provided. The actuating means is held on the housing by means of the elastically deformable material bridge.

  • Publication number: 20040129722
    Abstract: A miniature, stand-alone, countertop freezer primarily for domestic use, and a soft-serve dispensing method, that allows extended storage of a food product at an optimum soft-serve sub-freezing temperature prior to dispensing. Its housing has a compact configuration for freezer-like insulated food product storage. However, when soft-serve dispensing is desired, the housing is vertically extended to expose a decorator pattern cap. A press plate in the upper portion of the housing is activated, either manually or otherwise, to push downwardly on the food product container, and thus force the food product through the pattern cap below the food product container and into a receiving vessel. The pattern cap may be a part of the dispenser or a part of the food product container. Although not limited thereto, use is contemplated with ice cream, sherbet, yogurt, sorbet, and other frozen dessert products. Alternative power supply sources are contemplated.

  • Patent number: 6732771
    Abstract: Edible frozen product extruding machine of the type using cartridges (3) which contain the frozen product (4) provided with an extrusion nozzle (5) and which rest on a platform (2), inside which cartridge acts a piston (6) which can move vertically by means of its stem (7) from the machine's driving devices, which centres its characteristics on incorporating to said stem (7) a side stop (8) which, in the downwards motion of piston (6) acts on a rod (9) which is parallel to stem (7) against the tension of a spring (11), which rod (9) is joined to a support (15) for cone (15) or vessel which receives the ice cream dose, so that with each operational cycle of the machine, initially cone (15) approaches nozzle (5) until the product is level with its opening, at which time stop (8) carries support (13) down, gradually distancing the cone from the nozzle as the classic overfilling of the cone is achieved, so that the frozen product considerably extends beyond its opening.
