Abstract: A fuel cell for use with a combustion tool for delivery of a predetermined amount of fuel with each stem actuation is provided and includes a housing defining an open end enclosed by a closure. A main valve stem has an outlet, disposed in operational relationship to the open end and reciprocating relative to the housing at least between a closed position wherein the stem is relatively extended, and an open position wherein the stem is relatively retracted. A fuel metering valve is located within the housing, associated with the main valve stem, including a fuel metering chamber disposed in close proximity to the closure and configured so that when the stem is in the open position, only a measured amount of fuel is dispensed through the outlet. In a preferred embodiment, the fuel cell housing includes a separate fuel container, and the fuel metering valve includes a valve body having a second end opposite the fuel metering chamber located within the container.

Abstract: In the present invention, an actuating mechanism for a hand held canister is provided in which a slider is moveable by finger pressure from a valve-disengaged position into a valve-engagable position and a concealed spring returns the slider to a valve-disengaged position when finger pressure is removed. The spring is preferably molded with the slider, projects through a slit in the over-cap of the canister and acts in a vertical plane against a stop depending from the over-cap. It is energised when the slider is moved into the valve engagable position. The slider is preferably releasably locked in the valve disengaged position.

The cap includes an atomizer nozzle (22) coupled to the discharge tube (18) and oriented approximately perpendicular to the long axis of the container. At the circumferential edge (28) of the container lid (13) there is formed at least one projection (32), which cooperates with a complementary recess on the inner circumferential surface of the atomizer cap (23) in order to achieve a rotationally stable fixation of the latter to the container lid (13), with the nozzle 22 located in accordance with the location of the end of pipe (21) within the container.

Abstract: The invention relates to a spray cap for aerosol containers comprising an integrally formed housing (1) comprising an actuating button (2) and an actuating lever (3), both flexibly connected to the housing (1). The actuating button (2) has a drive hook (18), which moves into interaction with a drive projection (19) disposed on the actuating lever (3) when the actuating button (2) is firstly moved radially and then axially. Due to the combined movements required for actuating the aerosol container, unauthorised use is to the greatest extent excluded. The actuating button (2) and actuating lever (3) are so designed that, via a recess (16) provided in the actuating button (2), the latter can be moved axially downwards without the drive hook (18) engaging with the drive projection (19) of the actuating lever.

The dispensing valve comprises a delivery tube that can be displaced, for example into the interior of the container and/or tilted about its long axis, against the action of a resilient means such as a spring. The delivery tube is coupled to an actuator defining an annular channel in such a way that the annular channel is in fluid communication with the delivery tube. The annular channel is closed by an annular closure flap which when opened under the pressure of the medium contained in the container defines an annular gap through which the medium can be discharged.
