Abstract

A container for a liquid or pasty cosmetic product has an elongate body, a reservoir that contains the product and is movable in translation in the body between a top working position and a maximum depressed position under the action of an elastically compressible device, and an application element secured to a cap that is retractable into the body and including a shaft that is secured to the cap and is terminated by an applicator suitable for being loaded with product when it is dipped into the reservoir; a peripheral part provided with a locking finger that is movable transversely and a more flexible internal part that are attached to the reservoir close to its edge in order to engage in terms of sealing with a widened portion of the shaft and to lock the latter to the reservoir over only a part of the travel of the reservoir.

First claim

The invention claimed is:

1. A container for a pasty or liquid cosmetic product, comprising:
an elongated body, extending in a longitudinal direction, provided with a bottom zone and a free edge;
a reservoir configured to contain the product, the reservoir being movable in translation within the body between a position of maximum pushing-in and a position of minimum pushing-in, the position of minimum pushing-in being a high working position;
the reservoir comprising a bottom and a free edge longitudinally remote from the bottom;
an elastically compressible device comprising a spring interposed between the body and the reservoir;
the elastically compressible device providing two stable axial configurations of withdrawal of the reservoir in relation to a configuration of maximum axial retraction demarcating a position of maximum pushing-in of the reservoir;
the two stable axial configurations comprising:
a maximum extension configuration of the reservoir demarcating the high working position of the reservoir; and
a stable retracted configuration demarcating a low resting position of the reservoir, the low resting position being intermediate between the position of maximum pushing-in and the high working position;
movement of the reservoir between the two stable axial configurations being made by retraction of the reservoir into the configuration of maximum axial retraction against the axial spring;

a cap;
an application member comprising a shaft joined to the cap;
an applicator terminating the shaft and configured to be loaded with an amount of the product when the applicator is plunged into the reservoir in a closing configuration in relation to the reservoir as the shaft traverses the edge of the reservoir;
the cap being configured, in the closing configuration, to be retracted at least approximately within the body and, when the reservoir is in the high working position, to project at least partly out from the body by a distance to enable a user to extract the application member out from the reservoir and from the body by means of the user grasping the cap and axially pulling the cap;
complementary members distributed on the shaft of the application member and on the reservoir proximate the free edge of the reservoir to axially link the shaft to the reservoir while ensuring sealing obturation of the reservoir at the free edge of the reservoir when the reservoir is in the maximum pushing-in configuration;
the complementary members comprising:
a peripheral part comprising:
an upper portion capping the edge of the reservoir while extending laterally to an inside surface of the body; and
a lower portion sealingly engaged in the reservoir proximate the free edge of the reservoir;

an inside part comprised of a material more flexible than a material of the peripheral part, the inside part being fastened to the peripheral part, the inside part comprising an inside skirt comprising an upper portion having an inside surface flared toward an outside of the reservoir;
a finger extending in the peripheral part for transverse movement of the finger between a position closer to the longitudinal direction and a position farther from the longitudinal direction, the finger comprising a head situated transversely outside the reservoir, but always inside the body;
a cam-forming surface provided on the inside surface of the body, configured to push the head towards the longitudinal direction during a descending movement of the reservoir into the body; and
a widened portion provided on the shaft at a location such that, when the application member is in the closing configuration in the reservoir, the widened portion is engaged by friction in the upper portion of the inside skirt and, in relation to the longitudinal direction, is at a lower level than a level of the finger.

2. A container according to claim 1 , wherein:
the cam-forming surface is configured to cooperate with the head of the finger over a longitudinal distance at most equal to one third of a range of movement of the reservoir within the body starting from the low resting configuration.

3. A container according to claim 1 , wherein:
the flared surface of the upper portion of the inside skirt of the inside part is connected to a formation in relief, or a hollow, configured to cooperate with a hollow, or a formation in relief, formed on the widened portion of the shaft.

4. A container according to claim 1 , wherein:
the inside skirt comprises a lower portion convergent towards the bottom of the reservoir and towards the longitudinal direction;
the shaft comprises a constricted zone situated longitudinally at a level such that, when the application member is in the closing configuration in the reservoir, a free edge of the lower portion of the inside skirt of the inside part is situated around the constricted zone.

5. A container according to claim 4 , wherein:
the lower portion of the inside skirt of the inside part extends, in the longitudinal direction, over a distance at most equal to half a distance over which extends the upper portion of the inside skirt.

6. A container according to claim 4 , wherein:
the lower portion of the inside skirt of the inside part has a lessening thickness along a direction toward the bottom of the reservoir.

7. A container according to claim 1 , wherein:
the widened portion of the shaft of the application member comprises a convergent portion extending from an upper edge of a flared surface of the widened portion towards the shaft, so as to force spreading of the finger in relation to the shaft during a longitudinal movement of removing the application member from the reservoir.

8. A container according to claim 1 , wherein:
the peripheral part and the inside part are made of moldable plastic materials.

9. A container according to claim 1 , wherein:
the body comprises an outside part and an inside part in which is provided the cam-forming surface.

10. A container according to claim 1 , wherein:
the inside surface of the body and the outside surface of the reservoir comprise complementary members constituting a point of increased resistance inducing resistance to a descent of the reservoir into the body from its high working position.
