Abstract
A fluid dispenser having a casing (E) provided with a dispenser head (11); and a refill cartridge (C) that includes a fluid reservoir (R). The refill cartridge (C) is axially insertable into the casing (E) in such a manner as to connect the fluid reservoir (R) to the dispenser head (11). The refill cartridge (C) and the casing (E) are provided with a connection mechanism (17, 253) that connects the refill cartridge (C) in the casing (E) by screw-fastening, so as to bring the fluid reservoir (R) into leaktight contact with the dispenser head (11). The movement, after screw-fastening, of the refill cartridge (C) in the casing (E) towards the dispenser head (11) delivers the fluid to the dispenser head (11).
Claims10
A fluid dispenser comprising:
- a casing that is provided with a dispenser head;
- and
- a refill cartridge that includes a fluid reservoir;
- wherein the refill cartridge is axially insertable into the casing in such a manner as to connect the fluid reservoir to the dispenser head;
- wherein the refill cartridge and the casing are provided with connection means for connecting the refill cartridge in the casing by screw-fastening, so as to bring the fluid reservoir into leaktight contact with the dispenser head, the movement, after screw-fastening, of the refill cartridge in the casing towards the dispenser head delivering fluid from the fluid reservoir to the dispenser head;
- wherein the connection means comprises:
- at least one cam path formed by the casing,
- a rotary actuator ring mounted on the casing, and
- at least one pin formed by the fluid reservoir, so that the pin engages in the cam path and follows the cam path while turning the rotary actuator ring.
A fluid dispenser comprising:
- a casing that is provided with a dispenser head;
- and
- a refill cartridge that includes a fluid reservoir;
- wherein the refill cartridge is axially insertable into the casing in such a manner as to connect the fluid reservoir to the dispenser head;
- the refill cartridge and the casing comprising connection means for connecting the refill cartridge in the casing by screw-fastening, so as to bring the fluid reservoir into leak tight contact with the dispenser head, movement, after screw-fastening, of the refill cartridge in the casing towards the dispenser head delivering fluid from the fluid reservoir to the dispenser head, wherein a rotary actuator ring is snap-fastened in removable manner on the fluid reservoir turning about an axis of the rotary actuator ring over an angular stroke that is limited by the connection means.
