Description

The present invention relates to a packaging for a consistency product. liquid to pasty. The invention is particularly suitable for packaging and to the distribution of cosmetic products such as care creams or gels.

The packaging of care creams is generally done in jars cosmetics. The use of these jars is simple: after opening the capsule, or from the cover, the user has direct access to the product; she takes manually inside the pot, the quantity necessary for its needs. The manual removal of product directly from the cosmetic jar requires however, a minimum of hygiene in order to avoid contaminating or polluting the product. Despite the additives and preservatives that protect the product, the ambient air enters in the packaging and can contaminate the formula.

New cosmetic jars have appeared on the market for several years skincare cream market. These new pots prevent the user from take the cream directly from the packaging, and at the same time substantially reduce the risk of pollution or contamination. In this packaging category, there is a pot surmounted by a flexible membrane pierced with a central orifice. By exerting pressure on the flexible membrane, it causes the opening of the orifice, and the exit of a quantity of product. By releasing the pressure on the membrane, the orifice closes, and the membrane returns to its rest position. When the membrane returns to its initial position, a depression is created inside the pot, which depression causes a piston located under the product to rise, thereby reducing the volume in which the cream is contained. Whatever resolving way acceptable the problem of air pollution and product contamination ambient, such a system has the disadvantage of requiring a number of parts important, as well as expensive and complex filling equipment, thus considerably increasing the cost price of these pots.

Patent FR 1,570,600 describes a device comprising a exterior packaging and interior packaging, in the form of a bellows, mounted on a piston. The displacement of the piston, from bottom to top, by so as to compress the bellows over use, and cause the exit of the product, is done either by a manual push directly on the bottom, or by rotation of the external packaging relative to a distribution device attached to the interior packaging. In the first case, the dosage of the amount of product dispensed is difficult to achieve precisely. In the second case, the rotation of one of the parts relative to the other causes the piston to rise, which includes a thread capable of cooperating with an additional thread provided on the internal surface of the packaging outside. Such a device has a number of drawbacks. Between others, the presence of a piston under the inner packaging, increases the number of parts and contributes to increasing the cost price of the assembly. By elsewhere, the internal surface of the external packaging must be threaded on substantially its entire height, so as to allow the emptying of all contents of the interior packaging.

US Patent 4,456,134 describes another packaging system in which, the volume of a receptacle is adjusted, by means of a flexible part, of the type bellows for example, and whose height can be reduced by screwing, one on the other, of two cylindrical parts forming an external packaging. The visible height of the container is reduced accordingly. In the same way that for the devices discussed above, this system is complicated and expensive.

It is known from patent application EP-A-0 406 134, a container comprising a bottle provided with an elastic section, which can be compressed against the intrinsic elasticity of the wall of the bottle. The elastic wall has only one and even the outer rib, the cap, complementary to the bottle, playing the role of nut, a non-return means making it possible to oppose the expansion of the bottle, under the effect of its elastic wall. One of the disadvantages of such a system is related to the fact that it is difficult to precisely dose the quantity of product distributed. This is very penalizing when on the one hand it is a question of distributing products, particularly in the field of luxury cosmetics, the price of which is relatively high, and for which it is desirable not to use more as necessary. Typically, such products are packaged in containers of low capacity, generally less than 50 ml. On the other hand, in particularly in the case of products containing treating active ingredients, especially during of their application on the skin, it is desirable not to apply more than necessary, so as not to unnecessarily attack the skin.

It is therefore one of the objects of the present invention to provide a packaging, especially for a creamy product, equipped with a mechanism simple and economical to allow the metered output of the product, while avoiding substantially any risk of contamination or pollution of the product.

It is another object of the invention to provide a packaging system, the filling of which can be carried out without substantially modifying the equipment used for this purpose.

Still other objects will appear in detail in the description which follows.

According to the invention, these objects are achieved by means of an X-axis container for liquid to pasty consistency product comprising: a) a cylindrical body exterior, one end of which has an opening; b) an internal receptacle disposed inside the outer body, and containing said product, said receptacle comprising a bottom, a flexible body, the external surface of which forms a net helical, said flexible body being surmounted by a portion passing through said opening and opening onto a dispensing orifice; and c) means provided on the inner surface of the outer cylindrical body, at vicinity of said opening, for in response to a relative rotational movement between said drive means and the flexible body, cooperate with the net helical, and cause the compression of the flexible body in the direction of said opening, as well as the outlet of the product through said dispensing orifice, means being provided for, during each use, inform the person who uses it on the quantity of product dispensed through said dispensing orifice.

According to a first embodiment, the container comprises means accessible from the bottom of the outer cylindrical body to cause said relative rotational movement between the flexible body and the drive means. Such means may consist of a member forming a bottom for said outer body, said member being rotatably mounted on the outer body, and being integral with said drive means.

Alternatively, the container comprises a cover, mounted to rotate freely on the second end, and carrying said orifice for dispensing the product, said body flexible being surmounted by a neck passing through said opening, and integral with said cover, said neck being in communication with the dispensing orifice, said relative rotational movement between the flexible body and the drive means being caused by a relative rotational movement between the outer body and the cover, said outer body being secured to the drive means.

The drive means are preferably located at an axial distance of the opening, so as to define between the opening and the drive means a space capable of containing substantially the entire flexible body in the compressed position. Such a characteristic allows a substantially complete emptying of the device containing the product.

The container preferably includes means for removably sealing said dispensing orifice. Such means may consist of a capsule articulated, by means of a film hinge for example. Alternatively, said means include an elastic member which, in the rest position, closes the orifice, and which is capable of deviating by bending under the pressure of the product, from so as to release said dispensing orifice, said elastic member returning by elasticity in the closed position when dispensing ceases. Advantageously, in the non-dispensing position, the elastic member rests on a rigid seat or semi-rigid. This last characteristic allows a clean exit of the product. The packaging is perfectly waterproof. It can be passed under the tap after use to clean it.

The bottom of the internal receptacle advantageously has a suitable re-entrant profile to the inner profile of the second end so as to promote emptying complete with internal receptacle, when the flexible body is fully compressed.

According to a specific embodiment, the drive means are worn by the internal surface of at least one angular portion of a cylindrical skirt, of outside diameter slightly smaller than the inside diameter of the outside body, said cylindrical skirt being mounted inside the outer body, and having a first end open, and a second end closed by a wall transverse, said transverse wall forming a bottom for said outer body. Such a characteristic facilitates the assembly of the assembly, and the realization of all by commonly used industrial techniques, in particular, molding using techniques such as injection blow molding, extrusion blowing, or rotational molding. The cylindrical skirt can be mounted inside the external body by gluing, snapping, welding, or screwing.

Preferably, the external body at its closed bottom, an orifice being formed in the outer cylindrical body, so as to allow the entry of air into a volume defined between the external body and the internal receptacle, in response to the compression of said flexible body. Such an orifice can be provided in the bottom of the outer body, or on a shoulder formed between the outer body and said opening.

Anti-return means can be provided to substantially prevent any relative rotational movement between the flexible body and the drive means in a direction likely to cause decompression of the flexible body. This characteristic prohibits any false operation, and in particular prohibits the formation of a volume of air in contact with the product, which could result from the decompression of the flexible body.

Such means may include at least one elastically deformable tongue disposed on an external surface of an annular ring provided on a shoulder located between the outer cylindrical body and said opening, and capable of cooperate with notches provided on a corresponding internal surface of the cover, said tab having a free end projecting into rest position relative to the external surface of the annular crown, and being oriented so that in a first direction of rotation of the cover by relative to the body, the tongue is urged by the notches, in a position substantially in alignment with said external surface of the annular crown, allowing the rotation of the cover relative to the external body, the free end tabs forming a stop, preventing rotation of the cover relative to the external body, in the opposite direction to said first.

The cover can be snapped onto the outer body by means of a groove / rib arrangement, so as to be free to rotate, and axially immobile. Advantageously, the cover is screwed onto the neck of the internal receptacle, and includes means for, when screwed completely, immobilize it axially in relation to the external body. Advantageously, the screwing of the cover on the neck of the internal receptacle is not inverted with respect to the helical thread of the flexible body, so as not to ability to detach cover from internal receptacle when dispensing product. The screwing of the cover on the neck ensures sealing, and allows the replacement of the internal receptacle, after use of its contents.

The means for indicating the quantity of product distributed through said orifice distribution may include a ratchet mechanism, capable of producing a audible, whenever a given amount of product has been dispensed.

Alternatively, said means comprise a mark provided on the cover or on the bottom of the outer body, and intended to be placed opposite graduations provided on the outer body. Such configurations allow dosing of the product to be distributed.

The drive means consist, for example, of at least a portion at least one turn of the helical thread, capable of cooperating with the helical thread formed by the external surface of the flexible body.

The flexible body can be made in the form of a bellows made of a material such as high or low density polyethylenes, polypropylenes, ethylene vinyl acetate copolymers, polyamides, polycarbonates, polyesters terephthalates, polyacrylonitriles, polyvinyl chlorides plasticized, polyurethanes, silicones, thermoplastic rubbers, thermoplastic elastomers, or a complex type polyethylene / polypropylene, polypropylene / polyamide, polyethylene / ethylene alcohol / polypropylene vinyl, etc.

Such a bellows can be produced by extrusion blow molding, injection blow molding, or rotational molding. The first two techniques are well known, and do not require no further description. According to the technique of rotational molding, a defined volume of polymer, in fine powder or in liquid state, is introduced into a movable closed mold, rotating along two axes perpendicular, at speeds between 10 and 40 rpm. The material is distributed evenly on the wall and gels when the mold is brought to a temperature between 200 ° C and 400 ° C. Cooling intense ensures solidification and allows demolding.

In the case of a multi-material container, it can be produced by co-injection blowing, or in coextrusion blowing.

The invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be explained below, with reference to nonlimiting exemplary embodiments, described with reference to the appended figures, among which:

• Figures 1A and 1B illustrate a first embodiment of the container according to the invention;

• Figures 6A and 6B illustrate another embodiment of the container according to the invention.

Figures 1A and 1B to which reference is now made illustrate a first embodiment of the container or pot according to the invention. Container 1, of axis X, comprises an external cylindrical body 2, of rigid or semi-material rigid. The outer body has in its upper part, substantially at level of its axis X, an opening 3, connected to the external body 2 by a shoulder 4. Typically, the outer body is made of a chosen material among polyethylenes, polypropylenes, polyvinyl chlorides, etc. the interior of the exterior body is disposed an internal receptacle 5, closed by a bottom 6, of profile returning towards the inside of the internal receptacle, and surmounted by a neck open 7, the external surface of which has a thread 8. The product P is contained inside the internal receptacle 5. The cervix emerges outside the body outside, through the opening 3. The internal receptacle 5 has a body flexible 9, in the form of a bellows, the outer surface of which forms a net helical 10. The bellows neck can form an integral part of the receptacle internal, and be produced by injection or bi-injection, extrusion or coextrusion, with the rest of the bellows. It is thick enough to give it a rigid or semi-rigid consistency, in order to allow the cover to be screwed onto the collar. Alternatively, the collar is mounted inside the bellows by gluing or welding.

The bottom of the outer body 2 is closed by an element 11 composed of a skirt cylindrical 12, with an external diameter slightly smaller than the internal diameter of the outer body 2, one end of which is closed by a transverse wall 13 forming a bottom for the container 1. The other end of the cylindrical skirt 12 is opened. The element 11 is mounted inside the outer body 2, and is held stationary in rotation, by breakdown, screwing, or welding. An air intake port 14 is formed in the transverse wall 13, so as to allow the entry of air in the volume between the outer body 2 and the internal receptacle 5, so as to compensate for the decrease in volume of the internal receptacle over the uses. The bottom 6 of the internal receptacle 5 has a recess 44 defining an internal profile similar to the profile of the interior surface of the shoulder 4, so as to allow a substantially complete emptying of the contents of the internal receptacle 5, as will be seen in more detail below. The axial height of the recess 44 is preferably substantially equal to the axial distance separating the thread 27 from the internal surface of the shoulder 4.

The internal surface of the element 11 carries, near the opening 3, a thread 27, able to cooperate with the helical thread 10 formed by the external surface of the body flexible 9, so that, by rotating, the flexible body 9 relative to the thread 27, there is a screwing of the flexible body 9 on the thread 27, thereby causing the ascent of the bottom 6, and the compression of the turns of the bellows, in the direction of the opening 3. The thread 27 has a V-shaped section oriented radially, and is disposed at an axial distance from the shoulder 4, such as the bellows, fully compressed, can be housed substantially in its entirety, inside the volume defined between the thread 27 and the shoulder 4. Typically this axial distance can vary between 3 mm and 15 mm. This distance can vary in a certain measure as a function of the axial height of the recess 44 formed through the bottom 6. In the same way as the outer body 2, the element 11, with the net 27, is made by molding of materials similar to those used for the outer body of the container.

The container is surmounted by a cover 15, having a transverse wall 16, breakthrough, substantially in its center, of a dispensing orifice 17. The orifice of distribution 17 can be removably closed by means of a capsule 18, articulated around a hinge pin 19, formed for example of a hinge movie. The internal face of the transverse wall 16 carries a first chimney axial 20, the internal surface of which carries a thread 21 capable of cooperating with the thread 8 provided on the external surface of the neck 7 of the internal receptacle 5. The screwing of the cover on the neck of the flexible body 9 is not inverted with respect to the screwing the helical thread 10 onto the thread 27. The inner face of the cover 15 carries also a second axial chimney 22, of slightly outer diameter smaller than the internal diameter of the neck 7 of the internal receptacle 5. This arrangement, in combination with screwing, ensures tight mounting of the cover on the neck of the internal receptacle 5. A side skirt 23 is formed by the periphery of the internal face of the transverse wall 16. This lateral skirt is of diameter external substantially equal to the external diameter of the body 2, and of internal diameter slightly greater than the external diameter of an annular crown 40 carried by the outer surface of the shoulder 4. The cover, thus secured to the internal receptacle 5, is mounted by snap-fastening on the annular ring 40, at by means of a groove 25 / bead 26 arrangement. Thus, the cover, integral with the internal receptacle 5, is free to rotate relative to the external body 2. The face upper of the annular crown 40 carries legs elastically deformable 30, 32, constituting non-return means whose operation will be described in more detail later.

Thus, to mount the container as shown in Figure 1A, the receptacle internal is introduced, before filling, or after filling, in the body outside, through the bottom. The cover is screwed onto the bellows collar, and slammed on the outer body. The bottom is then closed, taking care to engage the thread 27 with the helical thread 10.

To dispense a dose of product using the container in this mode embodiment of the invention, the cover 15 is rotated relative to the body exterior 2. This relative rotational movement causes the bellows relative to the thread 27, which causes the flexible body to be screwed onto thread 27, and the compression of the flexible body towards the opening of the external body, such as shown in the intermediate position of Figure 2A. Compression of bellows causes the product to pressurize and exit through the orifice distribution 17. As the uses progress, the turns are, as shown in FIG. 2B, compressed substantially in their entirety, inside the volume between the thread 27, and the internal wall of the shoulder 4. The bottom 6, the recess 44 of which has a profile similar to that of the internal surface of the shoulder 4, is substantially in abutment against said shoulder 4, via the upper transverse wall of the flexible body. This configuration allows substantially complete draining of product P. To replace the receptacle internal, in the case of a rechargeable system, the background is removed; the cover is detached from the external body, by extracting the bead 26, from the groove 25, then is unscrewed from the neck 7. The internal receptacle is thus free and can be extracted from the bottom.

Whatever not shown, means are provided to inform the user on the quantity of product distributed, thus allowing it to dose in a specifies the product sampled. Such means will be described in detail in the embodiment discussed with reference to Figure 5.

As it appears more clearly in the perspective view of FIG. 1B, the cover 15 has, on the outer surface of the side skirt 23, reliefs 28, of grooves or grooves type capable of promoting the rotation of the cover 15 relative to the external body 2. The capsule 18 has, substantially in its center, a pin 29 capable of fitting into the orifice of distribution 17 of the cover, and in sealingly closing said orifice 17.

The embodiment of FIG. 3 illustrates a variant of the embodiment discussed with reference to Figures 1A-1B, and 2A-2B. According to this variant, the container 1 comprises non-return means, the function of which is to prevent the rotation of the cover relative to the bottom in the opposite direction to that allowing the distribution of the product P. According to this variant, the shoulder 4 forms a annular ring 40, the outer edge of which is intended to receive by snap-fastening for example, the cover 15. The upper surface 34 of the annular crown 40 comprises elastically deformable tongues 30, 31, 32, 33, which have a free end 36, 37, 38, 39, protruding from the surface 34 on which they are arranged. The tabs are evenly spaced, and oriented along the annular surface of the annular crown 40. The surface inner cover 15, door in the vicinity of the side skirt 23, a plurality of notches 35 spaced regularly on the periphery of the cover 15. Thus, when the cover is slammed on the annular crown 40, by turning the cover in a direction such that the notches 35 come into contact with the tongues 30, 31, 32, 33, first at the end opposite the free end of the tabs (i.e., clockwise in the embodiment illustrated), the notches will press on the tabs, and urge their free end in alignment with the surface 34. After passing a notch, the free end of the tongue returns, by elastic return, to the projecting position relative to the surface 34. The cover can thus rotate relative to the body. In the sense of reverse rotation, the projecting end of the tabs forms a stop for the notches, thus opposing the rotation of the cover relative to the body. Others components of the device conform to what has been described with reference to Figures 1A-1B and 2A-2B, and therefore require no description additional detail.

In the same way as for the embodiment discussed with reference to Figures 1A-1B, and 2A-2B, means (not shown) are provided for inform the user about the quantity of product distributed, allowing her to accurately dose the sampled product. Such means will be subject to detailed description in the embodiment discussed with reference to FIG. 5.

FIGS. 4A-4B illustrate variants for plugging the orifice of distribution 17 of the cover 15. According to these variants, the selective closure of the dispensing orifice is made by means of an elastically member deformable 41 which, in the rest position, closes the orifice 17, and which is suitable for deviate by bending under the pressure of the product P, so as to release said orifice dispensing, said elastic member 41 returning by elasticity in position shutter when distribution stops.

In the embodiment of FIG. 4A, the elastically deformable member 41 forms a dome, having a slot 42 in its center. Organ 41 is maintained clamped between the upper edge of the neck 7 of the internal receptacle 5, and the cover, which is screwed onto the neck 7. In the rest position, illustrated in solid lines, the edges of the slot are joined, and the dispensing orifice is closed so waterproof. In the dispensing position, illustrated in broken lines, the edges of the slot 42 move away under the pressure of the product to let the product pass through P. When the distribution of the product ceases, the edges return to their joined position.

In the embodiment of FIG. 4B, the elastically deformable member 41 has a circular cut, interrupted over a small angular portion, of so as to define a circular closure element 43 articulated on the rest of the elastically deformable member 41. In the rest position, illustrated in lines continuous, the closure element 43 is in alignment with the surface of the cover 15, and closes the dispensing orifice 17. Under the thrust of the product, illustrated in discontinuous lines, the closure element 43 moves aside to let the product pass. Advantageously, in the non-distribution position, the closure element 43 rests on a rigid or semi-rigid seat so as to improve the tightness of the closing.

FIG. 5 illustrates another variant according to which means are provided for, during each use, inform the user about the dose of product dispensed. According to this variant, the outer body 2, defines in its upper part a step 141, on the wall of which there are graduations 45. The cover has a diameter less than the external diameter of the recess 141, and has a arm 46 oriented radially, the end 47 of which forms a reference point opposite the graduations 45. The arm 46 is advantageously used to drive the cover 15 in rotation relative to the external body 2. Thus, the user turns the cover 15 at an angle which is a function of the desired dose of product. The dosage is precise. The product distribution mechanism conforms to what has been described with reference to Figures 1A-1B and 2A-2B, and therefore does not requires no further description. Alternatively, the cover 15 is of external diameter substantially equal to the external diameter of the body outside 2, and bears directly on the outside surface of its lateral edge 23, a marker placed opposite the graduations 45 arranged on the outer body. According to another alternative, not shown, the means for informing the user on the dispensed dose, include a ratchet mechanism, capable of produce an audible sound, whenever a given amount of product has been distributed. For example, a pawl is secured to the bottom 6 of the flexible body 9. Bosses are suitably arranged on the inner surface of the skirt 12 (typically one boss per turn). Whenever the ratchet meets a boss, it produces an audible sound from the outside.

FIGS. 6A and 6B illustrate another embodiment of the container according to the invention. According to this embodiment, the cover 15, integral with the receptacle internal 5, is fixed in rotation relative to the external body 2. The bottom 13, integral with the thread 27, forms a ring, and is free to rotate (mounting by breakdown for example) relative to the external body 2, and therefore relative to the helical thread 10 formed by the bellows. The outer lateral surface of the ring also has streaks 28 so as to promote its rotation. Thus, by driving the bottom 13, in rotation relative to the outer body 2, we causes the rotation of the thread 27, in cooperation with the helical thread 10 formed by the outer surface of the flexible body 9. This relative rotation causes the compression of the bellows in the direction of the opening 3, and the distribution of the product as indicated with reference to Figures 1A and 1B. In the same way that for the previous embodiments, non-return means can be provided to prevent rotation of the bottom 13 in a direction capable of causing decompression of the flexible body 9, as well as means for informing the user on the dose of product dispensed.

As a purely illustrative example, a jar for care cream is produced, of a 50 ml capacity, using a 0.4 mm polyethylene bellows thick, with 6 turns. Net 27 is located approximately 5 mm from the edge upper body.

In the foregoing detailed description, reference has been made to modes of preferred embodiments of the invention. Obviously there may be variations made without departing from the spirit of the invention as claimed below.
