  • Patent number: 9296002
    Abstract: A sprayer portable on the back for spraying liquids comprises a tank (2), a hand lever (4), a pump (12) and a pressure vessel, wherein the pressure vessel is formed by a hollow space in the hand lever (4) and the pump (12) is arranged in the hollow space. The piston rod (13) of the pump is rotatably connected to a lever element (15) of the hand lever. A connecting sleeve (16) for a hose with a spray nozzle is integrated in the hand lever. The compact configuration of the sprayer allows a larger tank volume and more convenient operation. The sprayer can be manufactured at low cost due to the small number of components.

  • Patent number: 9139963
    Abstract: The invention relates to a portable scattering apparatus (1) for storing and dispensing granular material, especially pourable bulk material on a surface, e.g. of grainy fertilizer on a lawn surface, or scattering material on slick roads or paths. The scattering apparatus (1) contains a closable container (3) and a handle part (2) connected to the container (3) for dispensing the granular material. The handle part (2) comprises a lock chamber (4) in the connecting region of the container (3) for controlling the flow rate, and it is shaped into a distributor (5) at the front end. A valve (25) is arranged in the lock chamber (4), which valve can be actuated via a lever (11), which is pivotably held on the outside on the handle part (2). The lever (11) is connected via a valve stem (28) with the valve disk (26) of the valve (25).

  • Patent number: 8091744
    Abstract: The invention relates to an arrangement for pouring free-flowing media out of a container. The arrangement contains a pour-out valve (3, 50) which can be specifically opened and closed by the user via an easy to operate actuating device (9), and thus allows a controlled pouring-out action. A pour-out tube (2) arranged in a pivotable manner on the container (1) makes it possible, depending on the position of the pivoted pour-out tube (2), to lock or unlock the pour-out valve (3, 50) using a blocking device. Locking the pour-out valve in the closed position prevents accidental opening of the pour-out valve (3, 50). The arrangement according to the invention also contains a venting valve (8), which can likewise be locked in the closed state. A compression spring ensures that, in the rest state, that is to say when the actuating device (9) is not actuated, the pour-out valve (3, 50) seals off the spout and the venting valve (8) is likewise closed.
