Description

[0001] Bottle for liquid or viscous product

[0002] TECHNICAL FIELD OF THE INVENTION

[0003]

[0001] The field of the invention is that of the packaging and distribution of products of liquid or viscous consistency. The present invention particularly relates to the distribution of products in the cosmetic, pharmaceutical or food fields. It particularly relates to the distribution of creams, milks, liquids or gels (for example washing gels) intended to be applied to the body of a user. These products are typically contained in bottles provided with caps which have a transverse dimension of at most a few centimeters.

[0004]

[0002] The present invention thus relates to a cap, and a bottle comprising such a cap, for dispensing a liquid or viscous product, in particular a product intended for bodily application.

[0005] STATE OF THE ART

[0006]

[0003] Various cap structures (also called capsules) are already known for dispensing products contained in bottles on the neck of which such caps are mounted (in practice by screwing or clipping).

[0007]

[0004] Caps are known in particular which, in the closed configuration, have the appearance of simple screw caps, while in the open (dispensing) configuration, an upper part of the capsule is moved so as to allow product to exit through an outlet orifice.

[0008]

[0005] For example, document FR2954754 presents such a cap. Thus, this document presents a dispensing capsule for a bottle of product of liquid or viscous consistency which comprises a capsule body and a top piece adapted to be moved relative to this body between a closed configuration and a dispensing configuration. The capsule, and in particular its top piece, is configured so that the upper wall of the capsule is entirely constituted by the upper wall of the top piece, and the capsule and the top piece comprise complementary surfaces in the form of a portion of a sphere adapted to slide along one another from the closed configuration to the dispensing configuration and vice versa.Although this capsule is particularly practical and aesthetic, it is desirable to develop other caps offering alternative kinematics, in particular in which any movable part of the cap does not protrude transversely from the rest of the cap. Furthermore, it is advantageous to provide a cap which can be detached from the rest of the bottle to allow the reservoir to be refilled when all the product it contained has been used.

[0006] Bottles of liquid product are also known which have a tip forming a cap mounted on their neck and the rotation of which allows the activation or deactivation of a pump.

[0009]

[0007] For example, document EP1954596 discloses a pump bottle which comprises a nozzle mounted on a case, the rotation of which makes it possible to raise or lower a pump activation button. More precisely, a pump is secured to a cartridge containing the product to be dispensed. This assembly comprises at least one protrusion which is placed in a set of guides in the form of ramps which the case comprises. The rotation of the nozzle causes the cartridge and the pump to be lifted, which frees the pump activation button for the user, to deliver the product by activating the pump by pressing this button.

[0010]

[0008] In a fairly similar manner, document WO2013178927 presents a bottle for dispensing a liquid product using a pipette. Thanks to a similar mechanism, the rotation of a cap initially allows an actuation button of the pipette to be lifted and then the cap to be unscrewed. Thus, with the actuation button released, the user can press it once to draw product into the pipette, then again to dispense the product.

[0011]

[0009] This type of kinematics, in which the rotation of a tip or cap causes a translation of a dispensing element of a bottle, is appreciated. Nevertheless, the known devices make it possible to authorize or prevent the actuation of a pumping mechanism, but they are not suitable for the dispensing of a product in the absence of such a pumping mechanism.

[0012] STATEMENT OF THE INVENTION

[0013]

[0010] The present invention aims to remedy all or part of the drawbacks of the state of the art cited above.

[0014]

[0011] To this end, the invention relates to a bottle for a liquid or viscous product, in which the bottle comprises a reservoir having an internal volume adapted to contain the product, the reservoir comprising a bottom and a neck which are opposite in a so-called longitudinal direction, the bottle further comprising a cap fixed on the neck of the reservoir.

[0015]

[0012] The cap comprises a body rotatable with respect to the reservoir and a dispensing nozzle forming a channel between the interior volume of the reservoir and a dispensing orifice. The cap comprises a mechanism configured to transform a rotation of the body into a longitudinal translation of the dispensing nozzle, between a lowered position in which a dispensing orifice is closed, and a raised position in which the dispensing orifice is released.

[0013] The cap comprises a sleeve fixed relative to the reservoir, the sleeve comprising a sealing portion which extends longitudinally at least partly inside the neck and which comprises an inner surface, the dispensing nozzle comprising a lower part mounted to slide longitudinally in said sealing portion so that a seal is produced between the inner surface of the sealing portion of the sleeve and a surface (for example an outer surface) of the lower part of the dispensing nozzle.

[0016]

[0014] Such a bottle has appreciable opening kinematics, and presents no risk of losing a cap. In addition, the proposed cap configuration, with in particular a sleeve which is fixed on the neck of the reservoir and which forms a sealing surface inside this neck makes it possible to ensure a seal for the product in the mechanism and more generally at the level of the cap.

[0017]

[0015] In order to form the mechanism, the body may comprise a ramp describing a portion of a turn and the sleeve may comprise a longitudinal guide, the dispensing endpiece comprising at least one pin, the pin extending into the longitudinal guide and being engaged in the ramp.

[0018]

[0016] Alternatively, in order to form said mechanism, the sleeve may comprise a ramp describing a portion of a turn and the body may comprise a longitudinal guide, the dispensing endpiece comprising at least one pin, the pin extending into the longitudinal guide and being engaged in the ramp.

[0019]

[0017] The dispensing nozzle may comprise two parts mounted free to rotate, namely the lower part comprising the sealing portion and the pin, and an upper part comprising the dispensing orifice, the upper part being blocked in rotation with respect to the sleeve.

[0020]

[0018] The sealing portion may be slightly conical and may include a deformable thinned end portion which is in contact with the lower portion of the dispensing nozzle.

[0021]

[0019] An annular seal may be interposed between the sealing portion of the sleeve and the lower part of the dispensing nozzle.

[0022]

[0020] The sealing portion may be straight cylindrical and the lower part of the dispensing nozzle may have a cross-section corresponding, within a functional clearance, to that of the sealing portion.

[0023]

[0021] The lower part of the dispensing nozzle may be cylindrical, for example cylindrical of revolution.

[0024]

[0022] The sealing portion of the sleeve and the lower portion of the dispensing tip may be dimensioned such that said lower portion of the dispensing tip extends longitudinally beyond the sealing portion, towards the reservoir of the bottle, both in the lowered position and in the raised position of the dispensing tip.

[0025]

[0023] The length of the sealing portion is advantageously greater than or equal to 2 mm, preferably greater than or equal to 5 mm.

[0026]

[0024] The bottle may include a valve at the dispensing orifice.

[0027]

[0025] The cap can be clipped onto the neck of the bottle.

[0028]

[0026] Alternatively, the cap may be screwed onto the neck of the bottle.

[0029]

[0027] The bottle may be configured so that, starting from the lowered position of the dispensing tip, a counterclockwise rotation of the body with a first minimum torque causes the dispensing tip to move into the raised position and then, the rotation being continued with a second minimum torque, greater than the first minimum torque, the rotation causes the cap to be unscrewed.

[0030]

[0028] The bottle may contain, for example, a serum, an oil, a milk, a liquid foundation, a washing gel, a shampoo, a low-viscosity cream, a lotion, or a makeup remover,

[0033] Figure 10 is a schematic sectional view of a cap used in another embodiment of the invention. DETAILED DESCRIPTION OF THE INVENTION

[0034]

[0030] The present description is given as a non-limiting example of an embodiment.

[0031] Figure 1 represents a bottle according to one embodiment of the invention. The bottle 1 has a conventional appearance, and comprises a reservoir 2 which provides an interior volume for containing a liquid or viscous product. As a simple example, the product may have a dynamic viscosity of between 0.8 m mPa.s and 1000 mPa.s. With such a viscosity, the product can be dispensed without it being necessary to exert pressure on the reservoir. The reservoir 2 can thus be rigid. However, as an alternative to a rigid reservoir, a deformable reservoir can be used for dispensing a product having a greater viscosity. By deformable reservoir, we mean a reservoir that a user can deform by hand, with a reasonable effort.

[0035]

[0032] The reservoir 2 comprises a bottom 3 and a neck 4 (not visible in FIG. 1, but visible for example in the sectional view of FIG. 4). The bottom 3 and the neck 4 are opposite in a so-called longitudinal direction L. The bottle 1 extends in the example shown along a main axis parallel to the longitudinal direction L.

[0036]

[0033] A cap 5 is fixed on the neck 4. The cap 5 has, in the example shown here, the appearance of a conventional screw cap.

[0037]

[0034] The cap 5 comprises a body 6 which forms its outer side wall. A rotation of the body 6, preferably in the conventional direction of unscrewing, i.e. counterclockwise, causes a dispensing nozzle 7 to come out as shown in Figure 2. The dispensing nozzle 7 comprises a dispensing orifice 8. The dispensing orifice is oriented transversely, i.e. perpendicular to the longitudinal direction L.

[0038]

[0035] Thus, a rotation of the body 6 causes a longitudinal translation of the dispensing nozzle 7. This rotation makes it possible to move the dispensing nozzle 7 from the lowered position shown in Figure 1 to the raised position shown in Figure 2. In the lowered position, the dispensing orifice 8 is closed, in this case by the body 6. The dispensing nozzle 7 then forms the upper surface of the cap 5. In the raised position, the dispensing orifice is free, so that the dispensing of the product contained in the reservoir is possible.

[0039]

[0036] To do this, the cap 5 comprises a mechanism making it possible to transform the rotation of the body 6 into a translation (preferably a simple translation, or possibly a translation combined with a rotation) of the dispensing tip.

[0040]

[0037] Figure 3 and Figure 4 represent a first example of a mechanism allowing this. For better understanding, the body 6 is shown in transparency in Figure 3. Figure 4 is a sectional view, along a plane AA shown in Figure 1.

[0038] The cap 5 comprises a sleeve 9 which is fixed on the neck 4. In the example shown here, the sleeve 9 is screwed onto a thread 10 of the neck 4. The tightening of the sleeve 9 on the neck 4 ensures its rotational locking, a relatively large force being necessary to cause its loosening.

[0041]

[0039] Alternatively, a fitting or clip-on attachment may be used, with a means locking the sleeve in rotation with respect to the neck.

[0042]

[0040] The dispensing nozzle comprises at least one pin 11, which extends transversely. In the example shown here, the dispensing nozzle comprises two diametrically opposed pins 11 (the sleeve here being generally cylindrical in revolution).

[0043]

[0041] The pin passes through a longitudinal guide 12, which is a longitudinal slot formed in the sleeve 9. The longitudinal guide 12 has a width I which corresponds to that of the pin 11 with a functional clearance allowing the pin to translate effortlessly in the longitudinal guide 12.

[0044]

[0042] The end of the pin is further engaged in a ramp 13. The ramp 13 is a groove formed on an internal surface of the body 6, in the thickness of said body 6. The ramp 13 preferably has a width L which corresponds to that of the pin 11 with a functional clearance allowing the pin to translate effortlessly in the ramp 13.

[0045]

[0043] The ramp 13 forms a portion of a turn, for example about a quarter turn. The ramp 13 nevertheless comprises two end portions 14 which are flat, that is to say they extend in a transverse plane (perpendicular to the longitudinal direction). The end portion 14 is better visible in Figure 6 which is described below. This end portion 14 is optional and provides a certain stability to the raised and lowered positions of the dispensing nozzle. It makes it possible to prevent the dispensing nozzle from being able, for example, to be retracted into the body 6 by pressing on it longitudinally: when the pin 11 is in the end portion, a rotation of the body is necessary to engage the pin in the portion of the turn formed by the ramp 13. Conversely, in the absence of a flat end portion 14 the bottle can be closed by simply pressing on the dispensing nozzle, in the longitudinal direction.The bottle can then be closed either conventionally by turning the body 6 of the cap, or using a very simple gesture by pressing on the dispensing tip which then causes the body 6 to rotate, which can be useful when the user has wet or slippery hands.

[0046]

[0044] Thus, the rotation of the body 6 causes (or follows) a relative movement of the pin 11 in the ramp 13, while the pin 11 (and therefore the dispensing nozzle) is kept fixed in rotation by the longitudinal guide 12. This results in a longitudinal movement of the dispensing nozzle 7.

[0047]

[0045] In order to allow rotation of the body 6, the latter is rotatably mounted on the sleeve 9. To this end, in the example shown, the sleeve 9 is provided with radial protrusions 16 and the body is provided, on the inner surface, with an annular groove 17 in which the radial protrusions 16 are engaged. Obviously, the protrusions 16 could be replaced by a peripheral bead. Furthermore, the protrusions (or the bead) could be formed on the inner surface of the body 6, while the corresponding groove 17 would be formed on the sleeve 9.

[0048]

[0046] It is notable that the cap is configured so that the torque required to cause the dispensing nozzle to move by turning the body 6 is less, and preferably much less, than the torque required to unscrew the cap from the neck. This prevents any involuntary unscrewing of the cap, but nevertheless allows the cap to be removed by continuing the unscrewing, with greater torque, once the dispensing nozzle has been brought into the raised position.

[0049]

[0047] As can be seen in particular in Figure 4, the dispensing nozzle forms a channel 15, which is free of any obstacle and which allows the product to pass from the reservoir 2 to the dispensing orifice 8.

[0050]

[0048] Unlike bottles comprising a pump in which the pump is fixedly mounted on the neck and in which it is easy to ensure a seal between the neck and the pump on the one hand, and in which the pump forms a sealed space on the other hand, it is necessary in the context of the present invention to ensure a seal between the neck and a moving part, namely the dispensing tip. However, the neck of bottles, in particular glass bottles, may have significant dimensional and geometric dispersions. This problem is resolved in the invention by providing the sleeve 9 with a sealing portion 18.

[0051]

[0049] The sealing portion 18 extends longitudinally inside the neck 4. The sealing portion has an inner surface 19 whose geometry and dimensions can be produced with very small tolerances. For example, the sleeve 9 can be made of injected plastic material, which ensures small dimensional tolerances. Any other manufacturing method offering a small tolerance and little dispersion can be used to produce the sleeve 9. Alternatively or in addition, the inner surface 19 can be ground by machining.

[0052]

[0050] The sealing portion extends over a certain length of the neck 4, for example over at least 2 mm, or even over at least 5 mm.

[0053]

[0051] The inner surface 19 therefore forms a surface of known and controlled geometry, with respect to which it is possible to form and guarantee a liquid seal.

[0054]

[0052] Thus, the dispensing nozzle 7 comprises a lower part 20 which is mounted to slide longitudinally in the sealing portion 18. The sealing can be obtained by the small clearance, or even the contact, between the sealing portion and a surface, namely in the example shown the external surface, of the lower part 20 of the dispensing nozzle 7. For this, the lower part 20 of the dispensing nozzle 7 can be cylindrical, with a cross-section corresponding, apart from a small functional clearance, to the internal cross-section of the sealing portion 18.

[0055]

[0053] Advantageously, the lower part 20 is longer than the sealing portion 18. In particular, the lower part 20 extends longitudinally beyond the sealing portion 18, both in the lowered position and in the raised position of the dispensing nozzle. Thus, sealing can be achieved over the entire length (i.e. the longitudinal dimension) of the sealing portion 18.

[0056]

[0054] As an alternative to this sealing produced between two corresponding surfaces, other means of producing it can be used as explained below.

[0057]

[0055] Figure 5 illustrates an optional valve that can be used in certain embodiments of the invention. The valve 21 is positioned at the outlet of the dispensing nozzle 7, and then forms the dispensing orifice 8. The valve 21 can be made of a flexible material, for example silicone. It prevents the flow of the product when the dispensing nozzle is in the lowered position. For example, the outlet surface 22 of the valve is then in contact with the inner surface of the body 6, which prevents any product from escaping.

[0058]

[0056] The embodiment of Figures 6 and 7 is essentially identical to that of Figures 1 to 5, except that this embodiment does not include a valve at the outlet of the dispensing nozzle. Therefore, the dispensing orifice can have a calibrated section, depending on the nature of the product contained in the bottle, to ensure dispensing with a flow rate that is neither too low nor too high. In the example presented, the section of the dispensing orifice is rectangular, so that this section can be relatively large despite a low lift of the dispensing nozzle. The unexpected exit of product is avoided by a good fit between the inner surface of the body 6 and the dispensing nozzle 7. Optionally, a flexible element, for example made of elastomer, can be positioned on the inner face of the body 6 opposite the dispensing orifice when the dispensing nozzle is in the lowered position.This flexible element then allows for perfect sealing at the dispensing orifice, when the bottle is closed.

[0059]

[0057] The embodiment of Figure 8 and Figure 9 differs from those of Figures 1 to 7 essentially by the mechanism allowing the dispensing tip to move from the lowered position to the raised position (and vice versa). In these figures, only the cap 5 is shown, the reservoir of the bottle being otherwise similar to that of the embodiments previously described.

[0060]

[0058] Figure 8 is a sectional view, along a plane equivalent to that of figures 4

[0059] In figure 9, the body 6 of the cap 5 is shown in transparency in order to partially show the mechanism of the cap.

[0061]

[0060] The cap comprises, as in the embodiments already presented, a sleeve 9 intended to be fixedly mounted on the neck of a reservoir, for example by screwing, a body 5 rotatably mounted on the sleeve 9, and a dispensing nozzle 7 which forms a channel 15 allowing the passage of the product from the reservoir to the dispensing orifice 8. Here, the dispensing orifice 8 does not comprise a valve, but it could quite easily comprise one.

[0062]

[0061] Like the embodiments already presented, the dispensing nozzle 7 comprises a pin 11 which is engaged in a longitudinal guide 12 and in a ramp 13.

[0063]

[0062] However, in this embodiment, the longitudinal guide 12 is formed in the thickness of the body 6, on its inner surface. The ramp 13 is formed through the sleeve 9.

[0064]

[0063] Therefore, during the rotation of the body 6, the pin 11 is also driven in rotation. Nevertheless, for aesthetic and practical reasons, it may be desirable for the dispensing nozzle to move from the lowered position to the raised position using a pure translational movement. For this, in the embodiment of FIGS. 8 and 9 the dispensing nozzle is made in two separate parts, namely the lower part 20 and an upper part 22.

[0065]

[0064] The lower part 20 and the upper part 22 are mounted to rotate freely relative to each other along a longitudinal axis. In the example shown, an annular protrusion 23 of the lower part is engaged in a corresponding annular groove 24 of the upper part 22, which allows rotation between these two parts.

[0066]

[0065] In order to block the upper part 22 in rotation, the latter is provided with a stop 25, here in the form of a longitudinal edge, this stop 25 being introduced into a longitudinal slot 26 formed in the sleeve 9. Thus, when the body 6 of the cap is turned, the lower part 20 of the dispensing nozzle moves longitudinally while turning, due to the progression of the pin(s) 11 in the ramp(s) 13, while the upper part 22, blocked in rotation with respect to the sleeve 9, has a pure translational movement.

[0067]

[0066] Another aspect is illustrated in Figure 8. Thus, in the device of Figure 8, the sealing portion 18 comprises a thinned end portion. Here, the thinned end portion comprises a chamfer formed on the side of the wall of the neck of the bottle reservoir. The sealing portion 18 is slightly conical, or narrowed at the thinned end portion. This thinned end portion is in contact with the lower portion 20 of the dispensing nozzle 7, which ensures a seal along the contact line (or the contact surface which has a short length). The flexibility of the thinned portion ensures its adjustment in contact with the lower portion 20. We can then speak of a linear seal. If necessary, the thinned end portion can form a lip in contact with the lower portion 20.

[0068]

[0067] In an alternative embodiment, one or more annular seals may be interposed between the dispensing nozzle 7 and the sealing portion 18.

[0069]

[0068] Figure 10 shows another embodiment of the invention. Just as in the embodiments shown in particular with reference to Figures 1 to 7, the cap 5 is fixed to the neck 4, via a sleeve 9 for example screwed onto the neck 4. The cap

[0070] 5 may also have in this embodiment the appearance of a conventional screw cap.

[0071]

[0069] As in the previous embodiments, the cap 5 comprises a body 6 which forms its outer side wall. A rotation of the body 6, preferably in the conventional direction of unscrewing, i.e. counterclockwise, causes the dispensing tip 7 to come out. The dispensing tip 7 comprises a dispensing orifice 8 oriented transversely, perpendicular to the longitudinal direction. The rotation of the body

[0072] 6 allows the dispensing nozzle 7 to move from its lowered position in which the dispensing orifice is closed to its raised position in which the dispensing orifice is released to allow the dispensing of the product contained in the reservoir. The dispensing orifice may include a sealing valve.

[0073]

[0070] The mechanism for transforming the rotation of the body 6 into a translation (simple or combined with a rotation) of the dispensing tip is similar to the mechanisms described for the previous embodiments.

[0074]

[0071] Compared to the embodiments previously described, the sleeve 9 comprises a longitudinal column 27. The column 27 is hollow and comprises, at its upper end 28, a transverse opening 29.

[0075]

[0072] The column 27 extends at least partly, longitudinally, in the neck 4.

[0076]

[0073] The dispensing nozzle 7 comprises a longitudinal tube 30 in which the column 27 is mounted, the column 27 being able to slide longitudinally in the tube 30. The tube 30 comprises a transverse lumen 31, which opens into a peripheral volume 32. The peripheral volume 32 is fluidically linked to the dispensing orifice 8.

[0077]

[0074] When the dispensing nozzle 7 is in its lowered position, the transverse opening 29 faces a wall of the tube 30. When the dispensing nozzle 7 is in the raised position, the transverse opening 7 faces the light 31, allowing the passage of the product contained in the reservoir into the peripheral volume 32 and finally towards the dispensing orifice 8.

[0078]

[0075] A sealing portion 18 is formed in the lower part of the column 27 of the sleeve 9, that is to say on the part of the sleeve 9 located wholly or partly in the neck 4. The wall of the column 27 thus forms at this level an interior surface 19. The interior surface 19 corresponds to the external surface of the column, which is on the inside with respect to the rest of the sleeve.

[0079]

[0076] A seal is formed between the sealing portion 18 of the sleeve 9 and the corresponding surface located in the lower part of the tube 30 of the dispensing nozzle 7. This seal can be achieved in particular in all the ways mentioned above with reference to the embodiments previously described.

[0080]

[0077] One of the advantages of the embodiment of Figure 10 lies in the fact that in the cap 5, the volume in which the product can be located remains constant, whether the dispensing tip 7 is in the lowered position or in the raised position. This avoids any risk of involuntary egress of product when the dispensing tip 7 is returned to the lowered position.

[0081]

[0078] The different ways described above of obtaining the desired sealing can be applied to the different embodiments of the mechanism.

[0082]

[0079] Thus, within the scope of the present invention, a bottle for a liquid or viscous product, such as a washing gel or a body cream, is proposed, the dispensing tip of which is raised or lowered, in order to free or, on the contrary, to mask and close the dispensing orifice, that is to say, in order to open or close the bottle. This opening and closing kinematics is intuitive (because the cap resembles a conventional screw cap, and opens and closes by rotation) and pleasant. The invention makes it possible to resolve the sealing problems that may exist due to dispersions in the manufacture of the reservoir, which may be made of glass or made of plastic material with relatively large tolerances.
