The present invention aims to further improve the device for applying cosmetics so that the applicator can be quickly and reliably attached to the container and released, and the applicator helps to apply the cosmetics. It offers many possibilities for designing components.

According to the first aspect, the present invention provides an instrument for applying cosmetics to a human keratin substance, such as skin or eyelashes, the apparatus being an applicator having a longitudinal axis.
Grip part,
Applicator parts and
A shaft portion that connects the grip portion to the applicator member and has a joint portion,
With an applicator and
A container configured to house an applicator,
The main body for containing cosmetics, and
A rotating member that is attached to the body and includes at least one locking member, with a locking position that prevents the applicator from being pulled out of the container by cooperating with the coupling portion of the shaft. A container is provided with a rotating member that is rotatable around a rotation axis with respect to a body and a coupling portion, between an applicator and an unlock position that allows separation of the container.

The present invention makes it possible to provide a compact structure in order to realize easy opening and closing of an instrument. The instrument may be configured to be easily opened and locked with only one hand, if desired.

In addition, by providing a coupling portion on the shaft of the applicator, the present invention provides greater design freedom for the grip portion, which interacts directly with at least one locking member. May not have at all.

For example, it is possible to have a flat and relatively thin grip.

The rotating member may be attached to the container, for example, via a support element fixed to the neck of the container. The support element does not have to be movable with respect to the body, for example snap-fitted to the neck. The rotating member may be rotatable with respect to the supporting element around the axis of rotation while being held axially on the supporting element.

The shaft may be provided under the joint with a sealed portion configured to airtightly close the container when the applicator is engaged with the container and the rotating member is in the locked position.

The instrument may include a wiping member fixed to the neck of the container. The wiping member may comprise an opening having an upper portion configured to at least partially accommodate a closed portion of the shaft. The sealing member is preferably made of an elastomeric material.

The maximum lateral dimension of the top of the opening may be equal to or slightly smaller than the maximum lateral dimension of the sealing portion when observed along the longitudinal axis of the applicator.

The coupling portion may comprise at least one, more preferably two ribs, which may be symmetrical with respect to the other about the central plane of the shaft. The at least one locking member may be configured to press the top surface of the corresponding rib as the rotating member approaches the locking position.

Preferably, each rib is symmetrical with respect to the central plane of the applicator member.

Preferably, each rib has a depth measured along the radial direction of the applicator, which increases as it approaches the center of the rib and decreases as it approaches both ends of the rib. The depth of the rib may be zero at its end.

The upper surface of each rib may not be included in one surface. For example, the upper surface of the rib can form a ramp as the locking member approaches the locking position so that it further pushes the sealing portion against the wiping member, which can enhance the tightness of the sealing. Moreover, thanks to such a configuration, when the locking member reaches the unlocked position, the application under the action of releasing the elastic restraint that occurs in the wiping member when the sealing member is pressed against the wiping member. The ta is partially pulled out of the container. Therefore, the ergonomics of the instrument is improved.

Each locking member may be composed of protrusions that are directed inward toward the axis of rotation.

The shaft portion may have a cross section cut along at least a portion of its length between the sealed portion and the applicator member so as to be orthogonal to the longitudinal axis of the applicator, which is a non-circular shape. It may preferably have an elongated shape along the extension axis, such as a rectangle or an ellipse.

The wiping member may have a lower portion that defines the wiping slot. This makes it possible to realize a more appropriate wiping operation when the applicator member has a corresponding flat cross section.

In another aspect, the invention provides a method for applying cosmetics to a person's keratinous substance using the packaging and applicator device according to the invention as defined above, the method of which is in a container. Includes a step of inserting the applicator into the container and a step of engaging the locking member with the coupling portion at the locking position of the instrument by rotating the rotating member with respect to the container.

The device 20 includes a container 12 containing a product to be applied and an applicator 10 configured to be housed in the container 12 during storage.

As shown in FIG. 1D, the applicator 10 includes a grip portion 16 on the proximal side and an applicator member 26 on the distal side. The applicator member 26 is connected to the grip portion 16 via a shaft portion 6 extending along the longitudinal axis X of the applicator 10.

The applicator member 26 may be overmolded or otherwise secured to the shaft portion 6.

As shown in FIG. 1 (d), the applicator member 26 may have one coated surface 27, which is, for example, a flat-shaped mascara brush.

As shown in FIG. 2, the shaft portion 6 may be connected to the grip portion 16 via an end portion configured to be inserted into the corresponding housing of the grip portion 16.

The container 12 includes a main body 2 and a neck 22 that defines an opening. The main body 2 of the container may be molded into one part together with the neck.

The container 12 further includes a wiping member 3, a support element 5, and a rotating member 4.

The wiping member 3 is fixed so as to be oriented so as to surround the axis of the neck, and is snap-fitted to, for example, the neck 22. The wiping member 3 includes two opposing tabs 33, which are a parallel rib 24 provided on the neck 22 and a main body 30 defining an opening 35 for inserting the shaft into the body 2. It is inserted into the corresponding housing formed between.

As can be seen in FIG. 3, the opening 35 may have a circular upper 38 and a lower portion with an inner lip 37, which inner lip is an applicator as can be seen in FIG. A wiping slot 39 is defined by extending at least a part in parallel with the longitudinal axis X of the above.

As shown in FIGS. 4 (a) and 4 (b), the rotating member 4 comprises a tubular skirt 40 which is rotatable around a axis of rotation Z and radially inward at its apex. It has an extending upper collar 43. The skirt 40 carries two oppositely opposed protrusions that make up the lock member 41. The lock member 41 is arranged downward in the axial direction of the upper collar 43, and projects inward in the radial direction toward the rotation axis Z. They are placed at a radial distance from the axis Z near the radius of the inner edge 49 of the upper collar 43.

The support element 5 includes a tubular sleeve 50, as shown in FIG. 5 (a). An annular bead 51 is placed on its outer surface near the lower end of the tubular sleeve 50. The support element 5 is snap-fitted to the neck 22 of the container 12 as shown in FIG. As shown in FIGS. 4 (a) and 4 (b), the rotating member 4 includes an arch-shaped tooth 44 snap-fitted to the annular bead 51 on the inner surface 46.

As shown in FIG. 5A, the support element 5 includes a lateral wall 53 extending inward in the radial direction. The inner ridge 52 projects upward from the lateral wall 53 and extends parallel to the axis of rotation Z.

As shown in FIG. 6, the inner raised portion 52 comprises two opposing raised portions 58, in which the rotational movement of the rotating member 4 moves the instrument to either the locked or unlocked position. At that time, the lock member 41 is configured to be stopped.

The tubular sleeve 50 comprises two opposing flexible tabs 77 above the annular bead 51, each with a protrusion 56. As can be seen in FIG. 6, the rotating member 4 is internally provided with four axial ribs 42 that are regularly spaced around the inner surface of the tubular skirt 40. When the applicator approaches the locked and unlocked positions, respectively, the protrusion 56 passes through the corresponding rib 42 thanks to the elastic deformation of the tab 77 before the locking member 41 abuts on each raised portion 58. It is configured as follows. In this way, a clipping action is provided that stably maintains the rotating member 4 in the locked or unlocked position.

The tab 77 defines the U-shaped slot 55 with the rest of the sleeve 50.

As shown in FIG. 4 (a), the tubular skirt 40 has an elongated cross section and has a wall that increases in thickness as it approaches both elongated ends thereof. The tubular skirt 40 comprises two inner cavities 45 in each of the opposite wall portions having the maximum thickness.

The tubular sleeve 50 further comprises, near its lower end, a notch 59 configured to slide over a corresponding protrusion 29 provided on the shoulder 25 of the container 12, as can be seen in FIG. This prevents the support element 5 from rotating with respect to the container 12.

The tubular sleeve 50 also contacts the lower surface of the lateral wall 53 with each side of the rib 24 of the neck 22 when the support element 5 is attached to the neck 22, as shown in FIG. 5 (b). The four contact portions 54 configured in the above are provided.

As illustrated in FIG. 2, the shaft portion 6 includes a sealed portion 63 in which at least a portion rests in the opening 35 of the wiping member 3 when the appliance is in the locked position. The sealed portion 63 may have a circular cross section when observed along the longitudinal axis X of the applicator 10 as shown in FIG. The sealing portion 63 has a diameter equal to or slightly larger than the diameter of the upper portion 38 of the opening 35 to ensure proper airtight sealing of the instrument in the closed configuration. The closed portion 63 is slightly tapered towards the applicator member 26 to facilitate the applicator into the opening 35 when the applicator 10 is reinserted into the container 12 after use, and the instrument is tightly closed Improve sex.

Over at least a portion of its length between the sealing portion 63 and the applicator member 26, the shaft portion 6 has an elongated cross section along the extension axis Y, preferably the lower portion 39 of the opening 35, as illustrated in FIG. It is possible to take a cross section having the same shape as. This helps prevent the applicator 10 from rotating while the rotating element 4 is operating.

Both the main body 2 and the rotating member 4 of the container 12 may have an elongated outer cross section along the same extension shaft as the shaft portion.

The annular skirt 40 of the rotating element 4 may have an elongated, eg, elliptical, cross section, as illustrated in the embodiments of FIGS. 1 (a) to 1 (c).

Since the main body 2 of the container 12 has a cross section having the same shape as the rotating member 4, the main body 2 can extend into the continuation portion of the annular skirt 40 when the applicator is in the locked position. The rotating member 4 with a non-circular cross section has the advantage of allowing the user to easily identify whether the instrument is in the locked or unlocked position. This also makes it easier for the user to rotate the rotating member 4.

The grip portion 16 of the shaft portion may have a non-circular shape as shown in the embodiments of FIGS. 1 (a) to 1 (d). For example, the grip portion 16 has a flat shape and has an elongated cross section along an axis Q orthogonal to the extension axis Y of the shaft portion 6. This makes it easier to grip the applicator 10 for applying the product.

The shaft portion 6 further comprises a coupling portion 64 placed above the sealed portion 63. The coupling portion 64 includes two ribs.

As shown in FIG. 7, the rib 64 is symmetrical with respect to the central plane of the applicator member 26 parallel to the extension axis Y of the shaft portion 6. Each rib 64 is symmetrical with respect to the central plane of the applicator member 26 orthogonal to the extension axis Y of the shaft portion 6.

Each rib 64 has a depth r measured in the radial direction of the applicator member, which increases from one end 67 of the rib 64 until it reaches a maximum and then decreases towards the other end 67. The depth r remains constant over the fan-shaped portion S forming the central angle of the rib 64 extending over an angle α varying from 10 degrees to 50 degrees, and more preferably from 5 degrees to 25 degrees.

In the illustrated embodiment, the locking and unlocking positions of the rotating member are offset by an angle of 90 degrees.

Preferably, both ends 67 of the rib 64 are installed along the extension axis Y of the shaft portion 6 as shown in FIG.

As shown in FIGS. 8 (a) to 8 (c), the upper surface 69 of the rib 64 may have an arcuate shape surrounding the longitudinal axis X of the applicator 10. As the protrusion 41 approaches the locked position, the inclination of the top surface 69 of the rib 64 pushes the applicator 10 toward the bottom of the container.

The shaft portion 6 further comprises an edge 65 above the rib 64. The distance d between the lower surface 70 of the edge 65 and the upper surface 69 of the rib 64 is larger than the height h of the lock member 41.

The edge 65 preferably has a circular contour when observed along the longitudinal axis X of the applicator 10, as illustrated in FIG. The edge 65 may have a constant depth R. Preferably the maximum depth r _max of the rib 64 is equal to the depth R of the edge 65.

As illustrated in FIG. 1A, when the applicator 10 is housed in the container 12, the applicator 10 is blocked by the rotating member 4 with respect to translation along the axis Z at the locked position of the appliance 20. Will be done.

At this position, the lock member 41 abuts on the rib 64 within the range of the annular fan-shaped portion S. Within such a fan-shaped portion S, the depth r of the rib 64 is shown in FIG. 9 because it is large enough to allow the rib 64 to engage the locking member 41. Thus, the applicator 10 is prevented from being pulled out of the container 12.

To unlock the instrument, the user rotates the rotating member 4 about 90 degrees around the axis Z, as illustrated in FIG. 1 (b). The applicator 10 is no longer blocked by the rotating member 4, and when the sealing member is pressed against the wiping member, the applicator is released as shown in FIG. 1 (b) by releasing the elastic constraints that occur within the wiping member. Partially withdraw from the container. The applicator can then be further withdrawn from the container 12 as illustrated in FIG. 1 (c). The rotation axis Z is the longitudinal axis X of the container 12 in the illustrated embodiment.

At the unlock position, the depth r of the rib 64 is zero, or too small to engage the locking member 41. As a result, the applicator translates freely along the axis of rotation Z.

As described above with respect to FIG. 6, the opposing raised portions 58 define the maximum angular movement of the lock member 41.

In the modified form illustrated in FIG. 10, the grip portion 16 has a circular shape like the skirt 40 of the rotating element 4 of the container 12.

The neck 22 of the container 12 is assembled to the main body 2 via, for example, snap fitting.

The upper surface 69 of the rib is included in a plane orthogonal to the longitudinal axis X of the applicator 10.

The present invention is not limited to the illustrated embodiments.

The applicator member may have two opposing coating surfaces.

The connecting portion 64 of the shaft portion 6 may take a shape different from that described above.

The shaft and / or grip may have other shapes, eg polygonal cross sections.

The applicator member may be molded or may include a foam, pencil, or flocked applicator member. For example, the applicator may be a mascara brush or an applicator for applying foundation, lip gloss, eyeliner, or nail polish.
