Description

RETRACTABLE COVERING SYSTEM AND PRODUCT PACKAGING AND APPLICATION ASSEMBLY EQUIPPED WITH SUCH

The present invention relates to a retractable cover system adapted to cover a handling element projecting from the neck of a product reservoir, and to a product packaging and application assembly, in particular cosmetic, hygienic or pharmaceutical product, equipped with such a system.

More particularly, the invention relates to a retractable covering system adapted to cover a handling element projecting from the neck of a product reservoir, said system comprising:

a mounting ring having a first longitudinal end adapted to be placed facing the reservoir and a second free longitudinal end and defining a longitudinal axis and an axial direction from the first end to the second end, and;

a cap movable in translation along the longitudinal axis relative to the mounting ring between an extended position in which said cap extends substantially projecting in the axial direction relative to said ring and a retracted position in which said cap is at less partially retracted in the direction opposite to the axial direction relative to said ring.

The document EP0987189 describes an example of such a system implemented so as to selectively cover and discover a spray head projecting from the neck of a product tank. In this document, the mounting ring is fixed at the level of the neck of the product reservoir and the displacement of the cap between the deployed position and the retracted position is controlled by means of a rotary ring fastened concentrically to the sealing ring. editing and on which a user can act. When actuated, the rotating ring drives the cap which has radial pins extending inward and cooperating with respective helical tracks provided on the mounting ring so as to selectively drive the cap between its deployed and retracted positions. , and to cover and discover the product spray head.

Such a rotary control covering system is not entirely satisfactory, in particular from the point of view of its ergonomics and ease of use. Indeed, the system described in the aforementioned document requires in particular the user to use both hands and / or resume several times to move the cap between its deployed and retracted positions.

Furthermore, in such a system, the friction existing between the cap and the fixed ring, and in particular between the radial pins of the cap and the helical tracks provided on the fixed ring, or between the cap and the rotary control ring. , can be relatively important and penalize the comfort of use of the retractable cover system.

Finally, when the covering system described in the aforementioned document is mounted on the neck of a product tank, it is necessary to provide an operating clearance between the rotary control ring and the shoulder of the product tank, which penalizes the aesthetic aspect of the whole and generates a risk of fouling likely to hinder the proper functioning of the recovery system.

The present invention is intended to overcome these disadvantages and aims to provide a retractable cover system of simple and intuitive operation, reliable operation and does not penalize the aesthetic appearance of the packaging assembly and application of product when it is set up at the neck of a product reservoir to selectively cover a handling member projecting therefrom.

For this purpose, according to the invention, a product packaging and application assembly of the aforementioned type is characterized in that it further comprises:

an elastic element urging the cap towards the deployed position, and;

- A reversible locking device for locking the cap in the retracted position.

With these provisions, the invention provides a retractable cover system having a simple operation, reliable and ergonomic, and whose use is particularly intuitive.

In particular, in the system according to the invention, the displacement of the cap between the deployed position and the retracted position, that is to say from the deployed position to the retracted position and vice versa, is effected by acting directly by manual support on the cap, this operation can be performed with one hand and in a particularly intuitive manner for the user.

In preferred embodiments of the invention, one or more of the following may also be used:

- The cap is guided relative to the ring so that the displacement of said cap is a translation movement without rotation;

- The reversible locking device defines at least a first stable position of the cap relative to the ring corresponding to the retracted position, and at least a first unstable position located beyond the retracted position in the opposite direction to the axial direction, and the passage of the cap from the deployed position to the retracted position is achieved by a displacement of said cap relative to the ring in the direction opposite to the axial direction to the first unstable position, followed by a displacement of the cap relative to the ring in the axial direction caused by the elastic element;

the reversible locking device defines a second stable position of the cap with respect to the ring corresponding to the deployed position, and a second unstable position situated beyond the retracted position in the opposite direction to the axial direction, and the passage of the cap of the retracted position in the extended position is achieved by a displacement of said cap relative to the ring in the opposite direction to the axial direction to the second unstable position, followed by a displacement of the cap relative to the ring in the axial direction caused by the elastic element;

- The reversible locking device comprises at least one follower pin integral with one of the mounting ring and the cap, and cooperating with a heart-shaped cam integral with the other of the mounting ring and the cap ;

the elastic element is in the form of a spring having a first end bearing on the ring and a second end bearing on the cap.

According to an advantageous arrangement of the present invention, the reversible locking device comprises at least one flexible tab having a free end provided with the follower pin, said flexible tab being inclined in the direction of the longitudinal axis so that said follower pin exerts a force elastic in the radial direction on the heart-shaped cam. Thanks to these arrangements, the gaps that may exist between the mounting ring and the cap, due in particular to the manufacturing tolerances of these two elements, for example made of injected plastic material, may advantageously be caught by the elastic force generated between these two parts at the reversible locking device.

Preferably, the locking device comprises two flexible tabs provided diametrically opposite and each having a free end provided with a follower pin cooperating with a respective heart-shaped cam, said flexible tabs being inclined towards the longitudinal axis so that each of said follower pins exerts an elastic force in the radial direction on said respective heart-shaped cam. This gives a self-centering effect of the cap relative to the mounting ring, in addition to a catch-up effect of games that may exist in the assembly of these two elements.

According to another advantageous arrangement of the present invention, the handling element being movable relative to the neck of the reservoir between a rest position and a position of use, the retractable covering system further comprises a locking device of the handling element in the rest position when the cap is in the deployed position, the passage of said cap in the retracted position causing the unlocking of said handling element. The use of the manipulation element is thus prohibited as long as the cap is in the extended position of covering thereof.

Preferably, this locking device of the handling element comprises at least one tilting tab secured to the mounting ring and having a locking portion, an unlocking portion and a tilting axis, said locking and unlocking portions s extending on either side of the tilting axis, the locking portion cooperating with the handling element when the cap is in the extended position, and said cap being brought into cooperation with the unlocking portion during the passage from the deployed position to the retracted position so as to cause the tilting of the tongue about the tilting axis and the release of the locking portion relative to the handling element.

Advantageously, the locking device further comprises a tab integral with the ring and extending substantially along the longitudinal axis, and the axis of tilting of the tilting tongue is formed by at least one material bridge connecting said tab and said tilting tongue.

In a particular embodiment, the locking portion comprises a lug extending radially inwards and the unlocking portion comprises a ramp extending radially outwardly.

The invention also provides a product packaging and application assembly comprising:

a product packaging and application system comprising:

a product reservoir having a neck extending along a longitudinal axis and having an open free end, a shoulder, a side wall and a bottom, said shoulder radially connecting said neck to said side wall, and;

a product application device having a sampling portion adapted to be inserted through the open free end of the neck so as to extend at least partially inside the reservoir to withdraw the product contained therein and a handling member extending protruding from said neck along the longitudinal axis and adapted to be manipulated by a user to act on the pick-up portion and cause the product to exit the tank;

a retractable covering system as described above, in which: * the mounting ring is fixed concentrically on the neck of the tank, and;

* The cap laterally covers the handling element in the deployed position and at least partially discovers said handling element in the retracted position.

Thus, there is provided an assembly comprising a product packaging and application system equipped with a compact retractable covering system, extending from the neck of the product reservoir, and allowing a simple and intuitive way of selectively covering and uncovering a handling member extending projecting from said neck.

In a particularly advantageous embodiment of the present invention, the application device is a device for dispensing the product contained in the reservoir, the sampling portion comprising a pump attached to the neck of the reservoir, and the handling element comprising a push button movable relative to the pump between a rest position and an actuating position of said pump.

According to an advantageous arrangement of the invention, the pump is fixed on the neck of the reservoir by means of a hoop engaged around and above the open free end of the neck of the reservoir, the mounting ring being fixed on said neck by being engaged at least around said hoop.

Thanks to these arrangements, the mounting ring being fixed at the level of the neck of the reservoir by means of the fixing ring of the pump, the retractable covering system according to the invention can advantageously be used on different shapes of tank sections. , for example cylindrical, square, rectangular, or trapezoidal, with different sizes of tank neck adapting to the fastening band pump.

In general, the present invention is not limited to a given reservoir shape, for example the cylindrical shape described in detail below, which allows a large degree of freedom in the aesthetics of both the retractable cover system, that of the set of packaging and application, taken separately or in combination.

Alternatively, it could be provided that the application device is an applicator of the product contained in the reservoir, for example a cosmetic product such as a mascara, a gloss or a nail polish, the sampling portion comprising a rod which has a free end equipped with an applicator head adapted to be loaded with product and an end connected to a gripping element forming the handling element and closing the reservoir when it is in the rest position. In this case, the position of use of the gripping element corresponds to a position in which it is disengaged from the neck of the reservoir along the longitudinal axis and in which the sampling portion comprising the rod, as well as the applicator head loaded in product, is extracted outside said reservoir to apply the product on a surface, for example on the skin, on lips, on nails and / or on keratinous fibers (eyelashes, eyebrows, hair ...).

Other features and advantages of the invention will become apparent from the following description of one of its embodiments, given by way of non-limiting example, with reference to the accompanying drawings.

In the different figures, the same references designate identical or similar elements.

In Figure 1, there is shown in exploded perspective a cover system according to the invention, wherein the locking device of the handling element is not shown for reasons of clarity. This will be described in more detail in connection with FIGS. 2, 3 and 5.

As shown in FIG. 2, the invention relates to a product packaging and application assembly 1 equipped with a retractable covering system 2.

The packaging assembly 1 is for example intended to apply a cosmetic product, hygienic or pharmaceutical, liquid or pasty. It comprises a product reservoir 3 which has a neck 4 extending along a longitudinal axis X, this neck 4 extending from a shoulder 5 of the reservoir to an open free end 6. The shoulder 5 is located at upper end of a side wall 7 of the tank.

The packaging assembly 1 further comprises a product application device 8, comprising:

on the one hand, a sampling device 9, by example a pump adapted to the distribution of the product concerned, inserted through the neck 4 of the tank to take the product contained therein,

and on the other hand, a handling element 10, for example a push button projecting above the upper end 6 of the neck and carried by an actuating rod slidably mounted along the longitudinal axis. X at the upper end of the pump 9, the actuating rod being adapted to actuate the pump 9 and thereby cause the product to exit, for example through a dispensing nozzle or spraying 11 integrated pushbutton 10.

The push-button 10 is thus axially movable between a rest position illustrated in FIGS. 2 and 3, and an operating position of the pump 9 is depressed towards the neck 4 of the reservoir 3.

The pump 9 is mounted on the neck 4 of the reservoir by means of a hoop 12, made for example of plastic or other material, which is engaged above and around the upper end 6 of the neck 4. This collar 12 can for example be fixed to the neck 4 by clipping, or by any other means.

The neck 4 of the reservoir and the application device 8 are normally masked by the retractable cover system 2 mentioned above.

As can be seen in FIGS. 1 and 2, this retractable covering system 2 comprises:

a mounting ring 13 which fits on the outside of the band 12 being mounted concentrically on the neck 4 of the tank 3,

- A cap 14 movable along the longitudinal axis X with respect to the mounting ring 13 between an extended position visible in Figure 2 and wherein said cap 14 extends substantially projecting from the ring 13 and covers laterally the push button 10, and a retracted position visible in FIG. 3 and in which said cap 14 is at least partially retracted relative to the ring 13 and at least partially discovers in the axial direction X the pushbutton 10,

an elastic element 15, for example a compression spring, biasing the cap 14 in the deployed position, and

a reversible locking device, which will be described below and which is adapted to block the cap 14 in the retracted position.

The mounting ring 13 has a first longitudinal end 130 open in the axial direction X and adapted to be placed facing the reservoir 3, and a second longitudinal end 131 open in the axial direction X and free, and defines a longitudinal axis X and an axial direction S going from the first end 130 to the second end 131.

This mounting ring 13 comprises a fixed insert 16 intended to be fixed around the neck 4 of the tank 1 by resting on the shoulder 5 thereof, and a covering member 17 adapted to be fitted with clamping around the fixed insert 16. The fixed insert 16 may for example be made of plastic material, and the covering element 17 may be made of a metallic material.

In the illustrated embodiment, the fixed insert 16 is in the form of a generally cylindrical shaped element comprising a first radially inner skirt 160 engaged around and above the mounting collar 12 of the pump 9 on the collar 4 of the reservoir 3, a second radially outer skirt 161 on which is fitted, for example with clamping, the covering element 17, and an annular portion 162 radially connecting the lower ends of the first and second skirts 160, 161 and bearing on the shoulder 5 of the tank 3.

The cap 14 is movably mounted in translation along the longitudinal axis X with respect to the mounting ring 13 and is received between the first and second skirts 160, 161 of the fixed insert 16, and comprises a movable insert 18 which is in the form of a generally cylindrical shaped member open at its axial ends, and a covering member 19 adapted to be fitted, for example with clamping, around the movable insert 18 and having an upper end provided with a passage opening 190 for the push button 10, and a bearing surface 191 on which a user can act to move the cap 14 relative to the mounting ring 13 between the deployed position and the retracted position.

As can be seen in particular in FIG. 1, the cap 14 is guided with respect to the mounting ring 13 by means of two pairs of longitudinal ribs 180 provided diametrically opposite on the inside face of the movable insert 18 and cooperating with each other. with the lateral faces of two portions 162 projecting in the radial direction from the outer face of the first skirt 160 of the fixed insert 16, so that the displacement of the cap 14 relative to the mounting ring 13 either a translation movement without rotation.

The elastic element 15 is in the form of a helical compression spring having a first end bearing on the fixed insert 16 of the mounting ring 13 and a second end bearing on the movable insert 18 of the cap 14.

The reversible locking device of the cap 14 in the retracted position relative to the mounting ring 13 comprises two flexible tabs 182 provided in a manner diametrically opposed on the movable insert 18 of the cap 14 and each having a free end provided with a follower pin 183 each cooperating with a heart-shaped cam 163 (inverted heart-shaped in the illustrated embodiment) formed in hollow on each of the protruding portions 162 of the inner skirt 160 of the fixed insert 16.

According to an advantageous arrangement of the invention, the flexible lugs 182 of the movable insert 18 are at least slightly inclined towards the longitudinal axis X so that the follower pins 183 exert an elastic force in the radial direction on the cams in the form of a heart 163.

As can be seen in particular in FIG. 4, which illustrates in side view the fixed insert 16 of the mounting ring 13, each heart-shaped cam 163 forms a continuous track of circulation of the follower pin 183 having a retraction path. 164, a deployment path 165, an upper joining portion 166 connecting the retraction and deployment paths 164, 165, and a lower joining portion 167 connecting the retraction and deployment paths 164, 165 and formed of a first and second panels 168, 169 inclined downwards.

Each heart-shaped cam 163 thus defines four particular positions for each follower pin 183 (shown in dashed lines in FIG. 4 according to these four particular positions), namely:

a first stable position PSI corresponding to the retracted position of the cap 14 with respect to the mounting ring 13 and in which the associated tracking pin 183 is stably received and locked in the axial direction S in the lower junction portion 167 the heart-shaped cam 163;

a second stable position PS2 corresponding to the extended position of the cap 14 with respect to the mounting ring 13 and wherein the associated follower pin 183 is stably received and axially locked S in the upper junction portion 166 of the heart-shaped cam 163 ;

a first unstable position PII situated beyond the first stable position PSI in the opposite direction to the axial direction S and in which the associated tracking pin 183 is unstably located at the lower end of the first inclined face 168, and;

a second unstable position PI2 located beyond the first stable position PSI in the opposite direction to the axial direction S and in which the associated tracking pin 183 is unstably located at the lower end of the second inclined section 168.

In the exemplary embodiment illustrated, each heart-shaped cam 163 defines a closed circulation track for each associated follower pin 183 and the locking in the axial direction S of the cap 14 in the deployed position with respect to the mounting ring 13 is achieved at the blocking device.

In a variant, provision could be made for each heart-shaped cam 163 to define two half-running tracks open at their upper ends, the blocking in the axial direction S of the cap 14 in the deployed position with respect to the mounting ring 13 being able to then be provided by one or more stops provided on the cap 14 and adapted to cooperate with one or more corresponding stops provided on the mounting ring 13.

Furthermore, and as visible in Figures 2, 3 and 5, the retractable cover system 2 according to the invention further comprises a locking device provided to lock the push button 10 in the rest position when the cap 14 is located in the deployed position relative to the ring 13, and to unlock the button pusher 10 when the cap 14 is in retracted position relative to the ring 13 so as to allow the movement of the pushbutton 10 to its actuated position of the pump 9.

This locking device comprises two legs

20 diametrically opposite and extending substantially along the longitudinal axis X being connected to the radially inner skirt 160 of the fixed insert 16 via two radial joining portions 21.

Two cutouts, here C-shaped, are formed in each of the tabs 20 so as to define a rocker tongue 22 having a locking portion formed of a lug 23 extending radially inwards, an unlocking portion formed of a ramp 24 extending radially outwardly and a tilt axis formed by two material bridges 25 connecting the tilting tongue 22 to the lug 20, the lug 23 and the ramp 24 being located on either side of the tilting axis so as to form a tilting system.

The operation of the retractable covering system according to the invention will now be described with reference to FIGS. 2 and 3.

In the position illustrated in FIG. 2, the cap 14 is in the extended position with respect to the ring 13 and extends essentially in projection in the axial direction S with respect thereto so as to laterally cover the pushbutton 10.

Furthermore, in this position, the locking lugs 23 cooperate with the lower edge of the pushbutton 10 so as to prevent the latter from moving towards the actuating position of the pump 9.

Starting from this configuration illustrated in FIG. 2, a user holding the reservoir 3 in her hand presses on the cap 14, for example by means of her thumb, at the bearing surface 191 of the element dressing 19, so as to move said cap 14 in the opposite direction to the axial direction S against the force exerted by the spring 15.

During this movement, the follower pins 183 leave the second stable position PS2 defined at the heart-shaped cams 163 and navigate within the retraction paths 164 causing flexing of the flexible tabs 182 to reach the first unstable position PII. The follower pins 183 then leave the retraction paths 164 and are driven into the first inclined faces 168 by elastic return of the flexible tabs 182.

Meanwhile, during this movement of the cap 14, the push button 10 passes through the passage opening 190 formed on the covering element 19 of the cap 14, and the edge of said covering element 19 at the level of the orifice 190 comes into contact with the release ramps 24 which causes the tilting tabs 22 to tilt by twisting the material bridges 25 connecting them to their respective axial lug 20 so as to disengage the locking lugs 23 from the lower edge of the button push-button 10.

The user then stops pressing the cap 14, which causes the displacement of the cap 14 in the axial direction S and the displacement of the follower pins 183 to the first stable position PSI under the effect of the expansion of the spring 15 .

In this position illustrated in Figure 3, the cap 14 is locked in the retracted position relative to the ring 13 and discovers the push button 10 which can be depressed towards the neck 4 of the reservoir 3 to the actuating position of the pump 9 so as to cause the release of the product contained inside the tank 3.

Once the user has finished using the product application device 8 comprising the pump 9 and the push button 10, it again presses on the cap 14 at the bearing surface 191 of the covering element 19, so as to move said cap 14 in the opposite direction to the axial direction S, against the force exerted by the spring 15.

During this movement, the follower pins 183 leave the first stable position PSI defined at the heart-shaped cams 163 and navigate inside the second inclined faces 169 by causing flexing of the flexible tabs 182 to reach the second unstable position PI2.

The follower pins 183 are then facing the deployment paths 165, and are brought back to the second stable position PS2 under the effect of the expansion of the spring 15 when the user releases the pressure exerted on the cap 14.

At the same time, the edge of the covering element 19 at the orifice 190 is disengaged from the unlocking ramps 24, and the tilting tongues 22 are brought back to the locking position of the pushbutton 10 by elastic return of the material bridges. 25.

The product packaging and application assembly 1 equipped with the retractable covering system 2 according to the invention is then again in the configuration illustrated in FIG. 2, in which the push-button 10 is masked while being covered laterally. by the cap 14 in the extended position relative to the ring 13, and locked in the rest position by the locking lugs 23 cooperating with the lower edge of the pushbutton (10).
