An improved spray bottle (302) comprising a signalling device (301), whereby a time element or time module (306) is set into motion after the latest use of said spray bottle (302), e.g. after the latest actuation of the touch element or pressure element (305) pertaining to the spray device (301), and said time element or time module triggers a signal, e.g. an acoustic or visual signal, after a defined period of time. It is also possible to imagine the invention being used for the application of glue, whereby the adhesion capacity of the glue is indicated by the signal thus delivered.
