Abstract
The invention relates to a method for attaching lipstick to a lipstick dispenser and to a corresponding machine. The method for attaching lipstick to a dispenser, wherein the dispenser includes a distal end for the lips, and the dispenser includes a receptacle having an insertion opening fitted to a proximal end of the stick. The method includes: a moving step in which the insertion opening and the proximal end of the stick are moved adjacent to one another so as to substantially block the insertion opening; and a nesting step in which the stick is nested in the receptacle via a recess formed in the receptacle.

Method for attaching a stick of lipstick to a dispenser, the stick comprising a distal end intended for the lips, the dispenser comprising a receptacle having an insertion opening adapted to fit with a proximal end of the stick, said method comprising:
- a moving step in which the insertion opening and the proximal end of the stick are brought adjacent to one another so that the insertion opening is substantially blocked, and;
- a nesting step in which the stick is nested in the receptacle due to negative pressure created within the receptacle by a vacuum pump;
- wherein the receptacle has an internal area communicating with the outside via the insertion opening and via a port, an annular wall of the receptacle extending between the insertion opening and the port, said method comprising:
- a step of confining an area outside the receptacle which includes the port, wherein a chamber is connected in a substantially fluid-tight manner to the annular wall, the insertion opening remaining outside the chamber, and
- a step of creating a negative pressure inside the chamber so that this negative pressure is propagated into the internal area via the port.
Machine for attaching a stick of lipstick to a dispenser, the stick comprising a distal end intended for the lips, the dispenser comprising a receptacle having an insertion opening adapted to fit with a proximal end of the stick, said machine comprising:
- a moving mechanism for bringing the insertion opening and the proximal end of the stick adjacent to one another so that the insertion opening is substantially blocked, and;
- a device for creating negative pressure inside the receptacle so that the stick is nested inside the receptacle, said device comprising a vacuum pump;
- wherein the receptacle has an internal area communicating with the outside via the insertion opening and via a port, an annular wall of the receptacle extending between the insertion opening and the port, said machine configured to:
- confine an area outside the receptacle which includes the port, wherein a chamber is connected in a substantially fluid-tight manner to the annular wall, the insertion opening remaining outside the chamber, and
- create a negative pressure inside the chamber so that this negative pressure is propagated into the internal area via the port.
