Abstract: A dispenser for flowable media is provided, which operates in user-independent manner with respect to the pressure buildup and dosage quantity. On pressing on an operating head (35) a piston rod (29) is forced into a pump cylinder. As the pump chamber (52) is sealed by means of a delivery valve (51), which operates in path-dependent manner as a slide valve, under the action of a spring (42) pressing on the piston collar (43), a pressure builds up in the pump chamber (52), which is released following a predetermined length of travel on opening the delivery valve. A relatively constant pressure can be obtained over the entire discharge phase through the pretension of spring (42).

Abstract: A cap to be fitted on a double container including a flexible outer container and an inner bag, being composed of a main cap which has a flow opening for discharging the contents and is fixedly fitted on the neck of the double container and a nozzle cap which has an outlet for discharging the contents and is slidably fitted on the main cap. The cap makes a switch between a state with a flow passage shut and a ventilation passage open and a state with the flow passage open and the ventilation passage shut by vertical sliding movement of the nozzle cap on the main cap.

Abstract: A valve body has one or more integral seal retention grooves and one or more interior hollows which may be manufactured using frictional or other types of welding to join two previously formed portions through at least one cylindrical web. Forging or casting valve body portions to near-net-shape prior to joining minimizes machining necessary to achieve a final desired shape. One or more interior hollows and an integral seal retention groove are formed in the welded valve body from features present on the portions joined by welding to form the body. Increased valve durability and reduced metal wear arise from the reduced valve body weight and correspondingly reduced impact loading. An elastomeric seal may be cast and cured in place in a seal retention groove.

Abstract: An apparatus for discharging pressurized liquids at elevated positions includes a holding adapter, an actuating assembly, and an extension pole. The holding adapter includes first body member for holding a canister of pressurized liquid. The canister has an actuating stem extending from its top end thereof. An actuator nozzle is formed of an annular flange and a cap-like head portion. The head portion is disposed over the actuating stem. A handle portion is formed integrally with the first body member and extending downwardly from the holding adapter. The actuating assembly is telescoped over the canister and the holding adapter and includes a second body member for applying a downward force on the annular flange of the actuating nozzle to activate the actuating for discharging the pressurized liquid therefrom. The extension pole is operatively connected to a distal end of the handle portion and is adjustable to desired elevated positions.

Abstract: A device for packaging and dispensing of a cosmetic product which includes a container to hold the product, with the container being delineated by a body. A movable element moves relative to the container body and is capable, in response to an action exerted manually on a surface of an actuating element, of moving from a first position to a second position. The movable element incorporates a first lip intended to engage with an inner wall of the body, during at least part of its movement, thereby isolating a dose of product inside the container in a manner to cause its expulsion through at least one dispensing aperture. The movable element also includes an upper lip capable of being applied in a leaktight manner against the inner wall during at least part of its movement from the first position to the second.

Abstract: A container includes an inner layer portion for liquid, an outer layer having an inner shape substantially equivalent to an outer shape of the inner layer, with the outer layer having an air vent communicating from between the two layers and the ambient, and a dispensing portion. When liquid is dispensed, the inner layer peels off the outer layer. The inner layer and the outer layer are bonded, in a first region, to each other with a force such that the inner layer is peelable from the outer layer by change of pressure, and the inner layer and the outer layer are bonded, in a second region, to each other with a force which is larger than that in the first region, by which the inner layer peels off the outer layer in the second region after the inner layer peels off the outer layer in the first region.

Abstract: A toy water gun provides a plurality of nozzles for discharging water in a variety of directions, volumes or spray patterns. A multi-position trigger or similar device controls selection of nozzles individually or in combinations whereby an operator can quickly choose among various modes of discharge by moving the trigger through corresponding positions.

Abstract: A nozzle is attached to a tip of a fluid container which is formed of two flexible sheets overlapped with each other. The sheets have their internal surfaces fitted to each other in a normal state after contents are filled into the container such that even a very small portion of contents remaining in the container can be removed by a required amount without coming into contact with air.

Abstract: An assembly for packaging and dispensing a product, especially a cosmetic product. The assembly includes a container containing the product and delimited by a body, one end of which is closed by a bottom. A movable component is movable relative to the body of the container and is capable, in response to an action exerted manually on a surface of an actuation component, of passing from a first position in which the volume delimited between the movable component and the bottom of the container is a maximum, to a second position in which the volume is a minimum, so as to pressurize the product contained in the volume and deliver the product through at least one dispensing orifice. When the movable component returns from the second position towards the first, air passes into the volume through at least one passage formed between the movable component and an internal surface of the container.
