ABSTRACT:
The invention relates to a container such as a bottle or can made from sheet metal, plastic or any desired material, which is adapted for spraying. The container has a spray valve disposed on the top side, and a pumping attached to the bottom side of the container for generating excess air pressure in the container. The pumping device is connected with the interior space of the container via a first valve. The pumping device consists of two bellows tightly connected to the bottom side of the container and concentrically placed one inside the other. The inner bellows is tightly inserted in the outer bellows, which is designed as a bottom cap. A second valve is inserted in a bottom opening of the inner bellows. The container functions in such a way that lifting the container allows air to enter the inner bellows via the second valve. The second valve is configured so that air is not permitted to escape out of the inner bellows through the valve. Depressing the container against a support forces the air in the inner bellows through the first valve and into the interior space of the container.
