Abstract
A dispensing device including a cap having an insertion orifice and a stopper, the cap and the stopper being arranged so that the stopper is mounted in the cap on the side of the insertion orifice. The device includes a deformable chamber whose interior volume is arranged to contain a fluid, the chamber having an inlet to conduct a fluid along a circulation path of fluid from the inlet then through the chamber and to an outlet. The device further includes a pressing part arranged to be movable so as to modify the interior volume, and at least one reservoir film extending towards outside of the cap to form a fluid reservoir in communication with the chamber through the inlet, the at least one reservoir film being held by a force exerted by the stopper on the cap.
Claims17
A dispensing device, comprising:
- a deformable chamber whose interior volume is arranged to contain a fluid, said chamber being provided with an inlet so that the device is arranged to conduct a fluid along a circulation path of fluid from the inlet then through the chamber and to an outlet,
- a pressing part arranged to be movable so as to modify the interior volume,
- a dispensing valve which, in an open state, allows a passage of fluid from the interior volume of the chamber towards outside of the device through the outlet of the chamber and, in a closed state, does not allow the passage, wherein
- the pressing part is arranged to receive a pressing force,
- the chamber comprises a projecting part towards the outlet extending over a length of at least 3 mm and/or a distance between the closing of the valve and a center of the pressing part is more than 20 mm;
- and
- wherein the projecting part is arranged to fix or catch an applicator.
A dispensing device, comprising:
- a cap comprising an insertion orifice, wherein the cap includes a pressing part,
- a stopper, wherein the cap and the stopper are arranged so that the stopper is mounted in the cap in an insertion arrangement in the cap on a side of the insertion orifice,
- a deformable chamber whose interior volume is arranged to contain a fluid, wherein said chamber is provided with an inlet so that the device is arranged to conduct a fluid along a circulation path of fluid from the inlet then through the chamber and to an outlet, and the pressing part is arranged to be movable so as to modify this interior volume,
- a dispensing valve which, in an open state, allows a passage of fluid from the interior volume of the chamber towards outside of the device through the outlet of the chamber and, in a closed state, does not allow the passage, wherein
- the stopper forms an exchangeable refill of the device,
- the stopper comprises:
- a rear part comprising a film,
- the pressing part is arranged to be movable so as to modify the internal volume of the chamber,
- the internal volume of the chamber is delimited at least in part by the film disposed between the pressing surface and the chamber, and
- the film is in contact with the pressing part at least when a user presses on this pressing part to reduce the internal volume of the chamber.
A dispensing device, comprising:
- a cap comprising an insertion orifice,
- a stopper, the cap and the stopper being arranged so that the stopper is mounted in the cap in an insertion arrangement in the cap on a side of the insertion orifice,
- the device comprising a deformable chamber whose interior volume is arranged to contain a fluid, said chamber being provided with an inlet so that the device is arranged to conduct a fluid along a circulation path of fluid from the inlet then through the chamber and to an outlet,
- the device comprising a pressing part arranged to be movable so as to modify this interior volume,
- the device further comprising at least one reservoir film extending towards outside of the cap so as to form a fluid reservoir in communication with the chamber through the inlet, and
- the at least one reservoir film being held by a force exerted by the stopper on the cap.
