Abstract
Abstract A device for the dosed removal of granulates from storage containers, particularly hosehold packages of coffee, tea or the like. Underneath a discharge opening in the bottom wall there is a channel for the pushing in a spoon which is adjusted positively to the channel cross-section. A closure slider in the channel can be pressed back against spring action. The trough edge of the spoon spans a larger surface than that of the discharge opening and its front face edge which presses back the closure slider is adjusted to the shape of the front surface of the closure slider.
