Abstract
An antibacterial spray device is provided for spraying a liquid contained in a receptacle (R). The device comprises an endpiece designed to cover an outlet tube (G) of a pump (P) which is mounted on the receptacle (R) by a collar (C). The endpiece (1) includes an internal duct (11) which extends from the outlet tube (G) to an end cavity (10) and is surrounded coaxially by a tapering cylindrical outside wall (12), which is attached at its bottom portion to a bearing shoulder (13) for operating the pump (P). The end cavity (10) is provided with an ejection orifice (100) and houses a valve (2) therein. All component parts that come into contact with the liquid, including the endpiece, are made, at least in part, of a plastics material containing between 0.2% and 2% by weight of a bactericidal agent which acts solely by coming into contact with the liquid but without being released into the liquid.
