Benefits of technology
[0006]Consequently, there exists a need to improve still further devices that make it possible to create a hard point when opening or closing a screw-fastened container, and more generally to create a tactile sensation in any packaging, dispensing, or application device in which one part may turn relative to another.
[0013]The flexible tab of the invention is different from a tamperproofing tab and it may bend in reversible manner and without causing damage, including when the device is used for the first time.
[0014]By using a flexible tab in the invention, the problem of wear of the tooth or of deformation of the plastics material as in the prior art is avoided, and it is possible to benefit longer from the production of a satisfactory tactile sensation, but without making it more difficult to turn one part relative to the other.
Problems solved by technology
It is found that plastics material wears away and deforms after multiple successive openings of the container, such that said sensation tends to reduce in intensity, or even becomes imperceptible.
A solution consisting in increasing the size of the tooth so as to compensate for the wear of said tooth is not entirely satisfactory, since that increases the force to be exerted to open or to close the container, and that may be perceived negatively by the consumer.

Embodiment Construction
[0054]The packaging and dispenser device 1 shown in FIG. 1 comprises a container 2 and an applicator 3 that is fastenable in removable manner on the container 2.
[0055]As shown in FIGS. 3 and 4, the container may be made with a body 5 and a neck 6 that is externally threaded, for example. At the base of the neck 6, the container 2 may include a shoulder 7 from which a portion in relief 8 may project.
[0056]In the embodiment under consideration, the container 2 presents a shape that is elongate along a longitudinal axis X and it may be made by injection-molding or by blow-molding, amongst other possible techniques. Thus, the portion in relief 8 may be molded integrally with the neck 6 and out of the same material.
[0057]As shown in FIGS. 5 and 8 in particular, the applicator 3 may comprise a closure cap 10 and a stem 11 that carries an applicator member 12 that is, for example, a mascara brush, but that could be of any type, e.g. a flocked endpiece, a nail varnish brush, or an endpiece ...

A packaging and applicator device, including a first part; and a second part that is suitable for turning relative to the first about an axis of rotation; one of the parts including a resiliently deformable tab that is made in the thickness of a tubular skirt of the corresponding part, and the other part including a portion in relief, the tab and the portion in relief being arranged to co-operate in such a manner that turning the second part relative to the first causes the tab to pass over the portion in relief by bending, with a component of the bending being parallel to the axis of rotation, such passage over the portion in relief being accompanied by the production of a tactile sensation that is suitable for being felt by the user.
Description
[0001]The present invention relates to packaging and applicator devices, in particular devices used in cosmetics.[0002]For example, these may be devices containing a makeup or care product composition.BACKGROUND OF THE INVENTION[0003]It is known to make mascara packaging and applicator devices with a portion in relief on the container at the base of the neck and with a tooth on the closure cap, which tooth is capable of passing over the portion in relief by deforming resiliently in order to generate a tactile sensation that is felt by the consumer as confirming that the container is closed.[0004]It is found that plastics material wears away and deforms after multiple successive openings of the container, such that said sensation tends to reduce in intensity, or even becomes imperceptible.[0005]A solution consisting in increasing the size of the tooth so as to compensate for the wear of said tooth is not entirely satisfactory, since that increases the force to be exerted to open or t...
