Description

The present invention relates to the distribution of two products to be mixed extemporaneously, and more particularly but not exclusively, two products of hair coloring.

We know many devices for the extemporaneous mixing of two products stored separately.

Thus, we know from French patent application FR-A-2 732 245 a dispensing assembly comprising a body and a push button movable relative to this body to cause the simultaneous and separate distribution of two products from two containers in which these products are stored separately, each container being provided with a valve comprising a hollow actuating rod, the depression of which causes the distribution of the product.

A difficulty with certain known distribution assemblies stems from the fact that the actuating rods may have upper ends which are not located at exactly the same level taking into account manufacturing tolerances, which entails a risk of non-simultaneous distribution of products.

There is also a need to have a distribution assembly which can be easily modified with re-use of a large number of components when the nature of the products to be distributed changes, in order to be able to benefit an economy of scale in the manufacture of these.

Other distribution packages have been proposed, but do not offer full satisfaction.

By way of example, mention may be made of US Pat. No. 3,236,457, applications for European patent EP-A-0 313 414, EP-A-0 427 609 or EP-A 0 243 667, the patent British GB 1,163,978 or French patent applications FR-A-2,598,392 and FR-A-1 413 164.

The subject of the invention is a new distribution assembly which remedies especially the drawback mentioned at the start.

This new distribution assembly is of the type comprising a body and a actuating element movable relative to this body to cause distribution simultaneous of two products in the mixed or separate state, from two containers in which these products are stored separately. Each container can be provided with a pump or a valve comprising for example a hollow actuating rod. The sinking for example of such a hollow rod can cause the distribution of product.

The distribution assembly can be characterized by the fact that it includes a intermediate member separate from the actuating element and comprising for example two nozzles capable of engaging respectively on the two rods of the containers and by the fact that the actuating element and the intermediate member are arranged to cooperate in less during the operation of the actuating element, so as to allow the passage of products from the containers to the actuating element, the latter comprising at least one internal channel, allowing for example the flow of products to a distribution tip.

The invention allows satisfactory operation despite possible level differences between the upper ends of the actuating rods.

In addition, the way in which the products are brought to the element actuation, in a separate or mixed state, can be easily changed by changing simply the structure of the intermediate organ.

In a preferred embodiment, the actuating element is articulated.

The intermediate member advantageously comprises an outlet conduit by which take out the products in a separate or mixed state and the actuating element advantageously comprises a mouth suitable for receiving this outlet conduit.

The outlet pipe and the aforementioned mouth advantageously form a non-tight connection when the actuating element is at rest, which allows reduce the risk of jamming and self-operation.

The outlet duct can be received in the mouth of the element actuation with the possibility of angular movement around at least one axis geometric, even with the possibility of angular movement around two axes geometric perpendicular. Such a provision allows tolerances of relatively wide manufacturing in terms of the upper ends of the rods actuating.

In a particular embodiment, the body of the distribution assembly has inner tabs capable of snapping onto flanges formed on the containers.

In a particular embodiment, the actuating element is fixed by snapping onto the body.

More particularly, the body of the distribution assembly may include a slot and the actuating element may comprise at one end a tooth capable of snap into this slot.

The aforementioned slot is advantageously disposed set back from a wall against which is capable of abutting the actuating element when it is moved in a direction opposite to that causing the distribution, this wall preventing the user from raise the actuating element enough to be able to access the organ intermediate.

When the actuating element is pivoting, the latter has advantageously, when observed in profile in the geometric pivot axis, a general form of Γ.

The actuating element can be rigid. So the actuator may have at least one stiffening rib on an inner side, in which case the body of the distribution assembly may include a recess for accommodating this stiffening rib when the actuating element is moved towards its distribution position.

The actuating element may include a fixing element used for fitting of an attached distribution nozzle.

This dispensing nozzle can be fixed to the actuating element by screwing.

Alternatively, the dispensing tip can be fixed on the element snap actuation, with the possibility of rotation around an axis.

The dispensing tip can be straight or angled, depending on whether the dispensing is done upside down or upside down.

The free end of the dispensing tip can be bevelled, so that example to penetrate more easily into the hair to form a parting.

The actuating element may include a jet breaker, in particular when the products must be mixed before being distributed, which makes it possible to homogenize the more the mixture.

In a particular embodiment, the intermediate member comprises a part elongated tubular, closed at least at one end by a nozzle whose outlet orifice is blocked. The use of a nozzle to plug the elongated tubular part makes it possible to benefit from the wide availability of nozzles and their low cost, and avoids having to make a specific cap.

The distribution assembly may include at least one element of movable locking between a locking position and a dispensing position and to prevent, when in the locked position, a displacement of the actuating element sufficient to cause the distribution.

Such a locking element avoids the accidental risks of product distribution during transport.

In a particular embodiment, the locking element can rotate by relative to the actuating element, being integral with the dispensing nozzle and capable of come to bear on the body of the distribution assembly in the locked position.

Still in a particular embodiment, the intermediate member comprises at minus a longitudinal stiffening rib.

The body of the distribution assembly may have at its upper part reported closing elements, put in place after introduction of the member intermediate in the body of the distribution assembly, to maintain it at inside.

In a particular embodiment, the body of the distribution assembly has tubular spans defining housings intended to receive the receptacles and these scopes have grooves in which the organ is received intermediate.

Advantageously, the intermediate member comprises at least one rib engaging between these spans outside the housing and allowing the centering of the intermediate member inside the body of the distribution assembly.

The intermediate organ can be maintained with a sensitive play in the body of the distribution assembly when the actuating element is not operated and that the distribution assembly is waiting to be mounted on the containers.

The intermediate member can be arranged to channel the products up to the actuator.

The actuating element can then be arranged to channel the products to the dispensing tip.

The intermediate member can also, as a variant, be arranged to allow the mixing of the products before they reach the actuating element.

The dispensing nozzle may include a mixing element intended to promote the mixing of components. Such a mixing element can be arranged to forcing components to move in a non-purely axial direction, for example along a path comprising one or more generally helical portions.

The mixing element may comprise a succession of identical parts, crossed successively by the product. The mixing element can be produced outside the dispensing nozzle, and be immobilized axially inside thereof by abutment one end on a shoulder of the nozzle and by abutment at the other end against the part of the actuating element on which the nozzle is mounted.

When the actuator is not moved enough by the user, there is a risk that only one of the dispensing valves is actuated. To reduce this risk, the distribution assembly can be arranged so that the displacement of the actuating element beyond a predetermined stroke produces a audible click, perceptible by the user. So the latter knows that he has enough actuated the actuating element when it hears this audible click.

In a particular embodiment, the distribution assembly comprises at minus an elastically deformable tab which is deformed in one direction when the actuating element is moved to a certain threshold from an initial position of rest and which deforms in the other direction when the actuating element has crossed the aforementioned threshold. Such a tab can be made with the body of the assembly of distribution, for example.

In a particular embodiment, the body of the distribution assembly has two legs capable of being deformed by the movement of the element to activate an audible click.

The abovementioned leg or legs can be connected to a wall portion generally plane of the body and be arranged so as to deform out of the plane of this wall portion, during movement of the actuating element. A dimension or said legs can decrease towards the free end of each leg.

In a particular embodiment, two legs being produced on the body of the distribution assembly in order to produce an audible click when moving the actuating element, the latter comprises two ribs capable of pressing said legs. These ribs can be useful for stiffening the actuating element, especially when the latter has a general shape in Γ when observed in profile.

The invention also relates to a distribution device comprising a distribution assembly as defined above and two receptacles on which is fixed the distribution assembly.

The containers contain for example liquid or pasty products to mix extemporaneously.

The containers can be pressurized.

The containers can be fitted with valves and the actuating rod each container may have an upper end whose axial positioning is known with a tolerance greater than or equal to 0.2 mm, or even greater than or equal to 0.3 mm.

FIG. 1 shows a distribution device 1 comprising a distribution assembly 2 mounted on two containers 3 and 4 containing products to mix extemporaneously.

The distribution assembly 2 comprises a body 5 and an element actuator 6 provided with a fixing element 7 used for mounting a nozzle distribution, straight 8 as shown in Figure 2 or angled 9 as shown in figure 3.

The distribution assembly is shown in section in Figure 4 and we see on it that the body 5 houses an intermediate member 10 whose role will be specified more far. The intermediate member 10 and the actuating element 6 are distinct, being produced separately.

The body 5 is closed in the upper part by means of closing elements 11 shown individually in FIG. 5, arranged to snap into openings body correspondents 5.

Each container 3 or 4 is in the embodiment described of the type pressurized aerosol and comprises a valve provided with an actuating rod 15, as you can see it in figure 19.

The valve is held by crimping on a flange 16 'of the container.

The height of the upper end 17 of the actuating rod 15 is known with a tolerance of the order of 0.3 mm in the embodiment described.

The actuating rod 15 is hollow and the product is dispensed, when the actuating rod is pressed through it.

The body 5 has tubular bearing surfaces 16 split at the bottom for form elastic legs 17 provided on their radially inner surface each a tooth 18 capable of snapping behind a flange 16 'of the corresponding container.

The tubular bearings 16 are also provided on their surface radially inner axial ribs 19 whose lower end 20 serves as a stop limit switch for inserting receptacles 3 or 4 into the body 5 of the assembly distribution.

The tubular bearings 16 are provided in the upper part each with a groove 22 allowing the passage of the intermediate member 10, as will be specified more far.

The body 5 has an outer skirt 25 which covers its part lower the whole non-cylindrical upper part 26 of the receptacles 3 or 4.

The body 5 has an inner tab 26 which can be seen in the figures 7 and 8, crossed by a slot 27 which can be seen in FIG. 12, and the element actuator 6 has one end 28 provided with a tooth 29 capable of snap-fastening in the slot 27, the mounting allowing a possibility of pivoting of the element actuation 6 around a geometric axis of rotation perpendicular to the plane of section of Figures 7 and 8.

The body 5 has a passage 30 for the actuating element 6, this passage 30 being located on the side opposite to tab 26, which is set back from a wall 35 constituting a stop preventing movement of the actuating element 6 in the direction opposite to that causing the distribution, thus preventing the user from accessing the intermediate body 10.

The actuating element 6 is rigid and present when observed in profile as in FIGS. 7 and 8, a general shape in Γ.

The actuating element 6 has, on its inner side, as can be see in Figures 6 and 14 to 16, stiffening ribs.

More particularly, the actuating element 6 comprises two ribs of laterally extreme stiffening 40 as well as two stiffening ribs interior 41.

The body 5 has two recesses 42 for accommodating the ribs 41, as can be seen in Figures 8, 12 and 13.

The fastening element 7 is made in one piece with the element actuation 6, as can be seen in Figure 16.

The fastening element 7 is constituted in the embodiment described by an X-axis chimney, provided with a thread 44.

This chimney is extended below by a mouth 45, also on the X axis.

A jet breaker 46 is made in one piece with the actuating element 6, at bottom of mouth 45.

The intermediate member 10 comprises, as can be seen more particularly in FIG. 9, an elongated tubular part 47, of axis Y, open to a end 48, two end pieces 49 communicating with the interior of the elongated part 47 and an outlet duct 50 of axis Z perpendicular to the axis Y, located in a median plane at equal distance from end caps 49.

The intermediate member 10 comprises below, on the same side as the end pieces 49, a central stiffening rib 51, the ends 51 'of which are spaced apart from the end pieces 49 and two longitudinal ribs 52 each extending over the whole the length of the intermediate member 10.

The axes W of the end pieces 49 are perpendicular to the axis Y.

The upper end 55 of the end piece 49 is rounded, as can be seen in figure 9.

Each end piece 49 has a first portion 56 of its interior surface which is conical and connects at its top to a shoulder 57 against which can come in support the upper end 17 of the actuating rod 15 of the container corresponding.

The elongated tubular part 47 of the intermediate member 10 is closed to the end 48 by means of a nozzle 60 whose outlet orifice is blocked, as can be see it in figure 4.

When the intermediate member 10 is in place in the body 5, the end pieces 49 are positioned at the center of the respective tubular surfaces 16, the tubular part elongated 47 being received in the grooves 22 made in the upper part of these spans tubular 16, the central rib 51 participating in the centering of the intermediate member 10 in the body 5 while being able to bear by the ends 51 'against the spans tubular 16.

Given the internal shape of the end pieces 49, the latter are simply placed on the actuating rods 15 when the actuating element 6 is at rest, the actuating rods 15 not fitting tightly in the end pieces 49 that when the actuating element 6 is pressed and causes the depression of the intermediate organ in the body 5.

It will be noted that the rounded end 55 of the end piece 50 is received in mouth 45 with the possibility of angular movement around two axes perpendiculars, namely an axis parallel to the Y axis and a perpendicular to the defined plane by the Y and Z axes.

This connection, a bit like a ball joint, allows the intermediate organ to compensate for any difference in level between the upper ends 17 of the actuating rods 15 of the containers.

The distribution assembly 2 is placed on the containers 3 and 4 then that the intermediate member 10 is inside the body 5 and the actuating element 6 in square.

The distribution assembly 2 can be fixed by being lowered onto the containers 3 and 4 joined together, until the collars 16 'of the containers snap inside the tubular bearings 16.

The dispensing device 1 is used in the following manner.

The user screws a fixing nozzle 8 or 9 onto the fixing element 7 depending on whether the device is intended to be used upside down or upside down.

It will be noted that the dispensing nozzle 8 has a free end 70 bevelled, which facilitates the formation of a parting in the hair.

To cause the distribution, the user presses the element actuation 6 in the direction of arrow U in FIG. 8.

The operation of the actuating element 6 causes the depression of the intermediate member 10 and the opening of the valves of the receptacles 3 and 4.

The products delivered by the latter mix inside the part tubular 47 arriving at the foot of the outlet duct 50.

The mixture then reaches the dispensing nozzle 8 or 9 to be dispensed on the hair for example.

To avoid mixing of the products contained in containers 3 and 4 to inside the intermediate member 10, an intermediate member 10 ′ can be used shown in Figure 17, which differs from that shown in Figure 9 in that the elongated tubular part 47 ′ is open at its two axial ends and by the fact that it internally comprises a partition 71 defining inside the outlet duct 50 two separate channels 72 and 73.

Thus, the products do not mix until the arrival in the distribution nozzle 8 or 9, which allows in the case of the use of certain products, to avoid the risks clogging.

The two ends of the elongated tubular part 47 ′ are closed by nozzles such as the nozzle 60 of the previous embodiment example.

The actuating element and the dispensing nozzle may include internal partitions allowing the two products to be transported without mixing them to the outlet of the dispensing nozzle.

To prevent accidental operation of the device, you can this one of a locking element making it possible to prohibit the sinking of the element actuator 6 in the locked position.

FIG. 18 shows a straight distribution nozzle 8 'which differs of that represented in FIG. 2 by the fact that it comprises at its base two fins 80 diametrically opposite and by the fact that it internally includes a bead ring 81 arranged to be snapped onto a fastening element similar to the fastening element 7 previously described, the thread 44 being however replaced by snap reliefs.

Thus, the dispensing nozzle 8 can rotate around the axis X between a dispensing position in which the fins 80 are located in the extension of the upper part of the actuating element and do not interfere with the penetration thereof and a locking position in which the fins 80 are able to bear on the upper wall of the body 5 on either side of the actuating element and preventing the depression of the latter.

The dispensing nozzle can receive a mixing element intended for promote the mixing of components.

By way of example, FIG. 20 shows an 8 "distribution nozzle. screwed onto an actuating element 6 identical to that previously described with reference in Figure 16. A mixing element 100 shown in isolation in Figure 23 is disposed at inside the nozzle 8 ". The mixing element 100 comprises a succession of sub-elements 100a and 100b, each of which forces the components to reach the end of distribution 8 "to make a non-straight path. Such a path is substantially helical, in the example shown.

The mixing element 100 bears at its upper end against a shoulder 85 of the 8 "nozzle and at its lower end against the upper edge of the fixing element 7. The end piece 8 "has at its base an annular flange 86 coming from bear against the actuating element 6 and a plurality of axial ribs 87, intended to facilitate the gripping of the 8 "dispensing nozzle when it is screwed on the actuating element 6.

There is shown in Figures 21 and 22 a body 5 'according to a variant of achievement.

The body 5 ′ differs from the body 5 previously described in that the recesses 42, intended to accommodate the ribs 41, are replaced by recesses 42 'whose shape is such that they define legs 120 intended to be deformed elastically when the user presses on the actuating element 6, so as to generate an audible click signaling that the user has pressed sufficiently the actuating element 6. In the illustrated embodiment, each tab 120 is connects to a generally flat wall portion 121, and has a free end 122 which is located on the path of the ribs 41 when the actuating element 6 is moved. Thus, the legs 120 are deformed towards the inside of the body 5 ′ outside the plane of the wall portion 121 when the actuating element 6 is pressed down to a certain threshold. When the actuating element 6 is moved beyond said threshold, the legs 120 tend to return by elasticity to their initial shape, which generates an audible click.

It will be noted on examining FIG. 22 that the width of the legs 120, measured parallel to the plane of this figure, decreases towards their free end 122. It will also be noted that the legs 120 are oriented obliquely with respect to a median axis M of the wall portion 121. The thickness of the legs 120, measured perpendicular to the plane of Figure 22, is substantially equal to that of the portion wall 121, so that the deformation of the legs 120 under the effect of the displacement of the actuating element 6 is accompanied by a slight deformation of the wall portion 121, tending to reinforce the loudness of the click emitted.

Of course, the invention is not limited to the exemplary embodiments which have just been given.

In particular, the dispensing nozzle can be produced differently and the locking element.

It is also possible to replace pressurized valve containers with containers pump.
