Abstract:
1. A flow rate regulator unit mounted in a casing section, comprising: a piston member, including an inner content passage inside the piston member, an opening in a sidewall of the piston member which is in fluid communication with the inner content passage, and an outwardly extending skirt on the sidewall of the piston member, the piston member movable from a forward position to a rearward position in response to pressure of content spraying gas in an aerosol container; a holding part, including an internal space for accommodating said piston member, where said piston member is movable, a hole in a sidewall of the holding part for allowing a content in the aerosol container to flow into a flow rate adjusting space located between said hole and the outwardly extending skirt of the piston member, the opening in the sidewall of the piston member being in fluid communication with the flow rate adjusting space when the piston member is in the forward position and the outwardly extending skirt blocking the fluid communication between the opening and the flow rate adjusting space when the piston member is in the rearward position, a receiving section for receiving a front end of the piston member, acting valve function therewith, and a mounting section on the sidewall of the holding part for connecting the holding part to a stem of the aerosol container; and an elastic member positioned between a rear end of said piston member and an inner rear end surface of said holding part for energizing said piston member in the forward position; wherein the holding part is a separate member from the casing section, and the casing section is composed of a single member which is movable in a downward direction, toward the aerosol container by a pressing operation by a user, and wherein the flow rate regulator unit is a unit structure independent from the casing section, and the flow rate regulator unit is mounted in the casing section and on said stem.
