CLEARANCE-FREE BUTTON FOR AEROSOL VALVE Russian patent published in 2009 - IPC B65D83/20 

FIELD: mechanics.

SUBSTANCE: invention relates to dispersion devices. The aerosol valve button contains the first box-like element and the second actuating element. The first box-like element is provided with side wall with inner and outer surfaces, open lower part for mounting on aerosol container and upper part with hole being provided in it. The second actuating element is installed underneath the first element and connected with it. The actuating element is ensured with actuated key, which is set in upper position to the said upper part, when it is released. There is a pipe coming out from the key to connect with aerosol valve and a discharge pipe coupled with the previous pipe and ended up with outlet nozzle. In the released position, the key's perimetre continues in radial direction behind the perimetre of the above mentioned hole made in the upper part of the first element. The key is provided with inner surface which is underneath when key is released and contacts with the upper part of the said first element in the adjacent area of the element hole. So no visible clearance is left between hole perimetre in the upper part of the first element and upper surface of the key. It prevents key pushing through the said hole while it is installed. The inner surface of the first element wall has holder extending further from it. There are slots made in the surface. The outlet nozzle of the second element has another holder with side extensions, which penetrate into the above mentioned slots when the first and second elements are assembled. The external end of the outlet nozzle is extended onward from the holder and implemented with sizes suitable for latching and extending into the hole in the said side wall.

EFFECT: reliable operation and reduced noise during dispersion.
