Abstract

A pressure spraying can, with spearate compartments for the ejected fluid and the expanding fluid has an opening in the bottom for insertion fo a needle to inject the expanding fluid into its compartment; this opening is also fitted with a filler device, comprising a non-return valve of polyurethane, fitted inside the opening and secured to the inner surface of the can bottom. Pref. the polyurethane has a Shore hardness of 30-35 at 22 degrees C, obtd. by 6-8 mins. hardening at 175 degrees C, followed by a longer standing time at room temp. Other props. at 22 degrees C are tensile strength, 12.5-15.82 kp/cm2; extension 550-650%; yield point 1.6-1.92 kp/cm2. The valve provides complete sealing, even after piercing with an injection needle.
