Abstract: A push button for a pressurised-product dispensing system, including an actuation body having an orifice for ejecting the product, a needle closing off the ejection orifice and a sleeve having a mounting well, the body being mounted to slide about the sleeve between high and low positions, forming between them a sealed space for conveying the product, the needle being associated with the sleeve by a link rotatably mounted on the sleeve to actuate the reversible movement of the needle between a closure position—or respectively an open position—of the ejection orifice when the body is in the high position—or respectively in the low position—, the needle provided with geometric means that interact with the body to exert a force holding the needle in a mounting position in which the needle projects from the body to enable the link to be associated with the needle.

Abstract: An application device for a liquid product, contained in a reservoir bottle having a lid for closing the opening of the bottle, through which at least one capillary migration channel for the liquid product passes towards a wetable surface on contact therewith is provided. Several similar capillary channels are preferably provided, which can alternatively function as openings for the entry of air through the lid. One of the ends of each channel opens outside the lid. The other end opens in a collector tube for the liquid product, contained in the bottle. The collector tube is embodied to hold a fixed amount of liquid product against gravity by capillary action, until the above is drawn off by capillary migration through the lid channels.
