A MI~ING AND METERING PUSH BUTTON
The present invention relates to a hand driven mixing dispenser device for two liquids, in particular for pharmaceutical or cosmetic use.
BACKGROUND OF THE INVENTION
~ uch devices are already known. In particular, devices are known including two receptacles each provided with a press-down actuator member (generally a valve), together with a single pushbutton enabling both members to be pressed down simultaneously (see the following patents in particular~
FR 1 216 596 Valois, FR 1 413 164 Egema, US 3 237 457 Kennedy et al., US 3 416 709 Spray-Tak, CH 399350 L'Oreal, etc.). The head of the pushbutton may include a mixing chamber, in which case the substances leave it mixed together, otherwise the substances may leave via two orifices that are separate, but generally very close together, with mixing taking place at the point of application or at the point of convergence of the two jets expelled. A device of this nature may operate as a pump, with actuation of the pushbutton providing the energy required for expelling the substances from the receptacles. The present invention relates more particularly to this case. The term "liquid" is used herein to cover any substance which is neither a solid nor a gas, i.e. substances which are sufficiently fluid to be capable of being pumped: liquids, lotions, semi-solids, etc. ... . The purpose of such devices is to dispense a mixture of various substances (where appropriate in the form of a spray), which substances should not remain mixed together for a longer than a certain length of time prior to use because of a risk of undesirable reactions or spoiling.
The object of the prèsent invention is to provide a pump of this type which is particularly advantageous from the manufacturing point of view. Another object of the invention is to provide a device of this type in which it is possible to `-`
adjust the proportions of the substances delivered on each occasion it is used.

Consequently, the present invention provides a hand driven ' . .

In an embodiment of the invention, the single pushbutton is fittable around at least one of the rods in such a manner as to enable it to slide along said rod in sealed contact therewith, and including a moving spacer enabling the axial -~

DETAILED DESCRIPTION ;;~
Figure l is a perspective view of an embodiment of a device in accordance with the invention. It is constituted by two identical or symmetrical flasks l and 2 which are semi-cylindrical in shape and held together by a head 3 and a base 4. In this example, the flasks æ e uncovered, however the base could extend further upwards and engage beneath the riM of the head. Each of the flasks is provided with its own pump crimped to its neck. The desi~n and structure of the pumps do not constltute a part of the present invention and they æ e both capable of being actuated in conventional manner by depressing a hollow actuating rod 5 or 5', with the substance being delivered via the central channel of the rod. The pumps are fixed to the flasks in conventional manner by means of cups 6 and 6' crimped to the necks of the flasks. A pushbutton constituted by the head 3 is engaged on both rods 5 and 5' as -described in the above-mentioned prior art patent.
As shown in the figures, an axial channel 7 communicates in sealed manner with the channel of the hollow rod 5', and a radial channel 8 communicates at one end with the axial channel 7 and its other end opens out to the outside. In the present lnvention, the above channel structure applies to one of the 25 flasks only, whereas in the prior art it applies to both i~
flasks.
In the prior art, both radial channels may open to the outside via adjacent orifices 9 and l0 which are independent from each other, as shown in the drawings, or else the two radial channels may meet i~sidé the pushbutton in a mixing chamber which in turns communicates with the outside via a single radial channel that opens out at a single point.
The operation of such devices is known. By pressing down the pushbutton, both pump rods 5 and 5' are pushed down. Each pump deiivers a quantity of substance. These two quantities are expelled via the axial channels and then via the radial channels, mixing in the mixing channel if there is one, or else at the outside where the jets meet.
~: : . - - - : ................. , . . ~ . .

The volume of each quantity of substance corresponds to the volume of the corresponding pump chamber for full depression of the pump rod. According to the invention, the extent to which at least one of the pump rods is depressed is itsel adjustable. This is achieved by means of a moving spacer 11 capable of presenting different thicknesses to the ~, end of the rod 5. In the example shown, the spacer is rotary.
The head 3 includes a cavity 12 on the axis of the rod 5. This cavity contains the moving spacer which is suitable for being rotated from the outside. The cavity 12 communicates with the outside via a radial outlet channel 13 and it is connected to the actuator rod 5 of the pump via which substance is delivered by means of a sliding seal 14, which is preferably integrally ,-molded with the head 3.
The spacer 11 is tablet-shaped, being provided with a peripheral collar 15 for holding it in place while allowing it to rotate, the collar 15 being suitable for sliding in a circular groove formed inside the head 3. This may be obtained by lding the head 3 with an appropriate cavity haviny an orifice in its bottom for fitting over the end of a rod 5. The cavity should have a circular step 16 on which the collar 15 is placed during assembly. A cover 17 is then placed thereover in order to hold the spacer in place. In one embodiment (as shown in Figure 2), the cover has a circular opening revealing the top surface 17 of the spacer. The cover 17 may be glued in place, snap-fastened, heat sealed, or ultrasonically welded, for example. The face 18 may be knurled and/or include positioning marks. The center of the spacer is situated to one side of the axis of the pump actuator rod 5. By rotating the spacer, the outer edge of its bottom surface is caused to move relative to the axis of the actuator rod 5. On this bottom edge, the spacer includes cams l9A, l9B, l9C, and l9D (Figure 5) of different lengths, each having a cross-shaped cut at its rod-engaging end for allowing the liquid to flow out from the rod during the delivery stage when the cam presses down on the end of the pump actuator rod.
r It wIll be understood that, depending on the length of the cam placed in line with the actuator rod 5, the cam will make contact sooner or later with the end of the actuator rod when the pushbutton 3 is depressed, and consequently the rod will execute a greater or lesser stroke causing the pump to deliver a greater or lesser quantity of substance.
For reasons of symmetry and appearance, a second knurled portion 20 is shown on the top of the pushbutton 3. Naturally both pumps could be controlled ln the same manner, thereby offering a wider choice of ratios between the dispensed quantities of the two components, and also making it possible to select the total quantity that is dispensed.
In another embodiment as shown in Figure 8, the cover 17' does not have a top opening and it overlies the spacer ll' completely, while nevertheless allowing it to ro~ate by leaving a slot 31 in the edge of the pushbutton adjacent to the location of the spacer, said slot extending between the bottom surface of the cover and the facing top surface of the head 3' of the pushbutton. The spacer 11' is provided with an arm 33 ,~
which passes through said slot and projects to the outside, thereby enabling the spacer to be rotated. Reference marks may be provided on the side of the cover 17'.
The figures show two semi-cylindrical flasks which together constitute a cylindrical assembly. It is also possible to use two cylindrical flasks disposed side by side in a somewhat flatter case.
In the variant of Figures 6 and 7, a flap 25 is provided for closing the outlet orifices 9 and 10 of the channels through which the liquids are expelled. The flap may be provided with studs 26 and 27 which engage in said orifices in order to close them more completely and hold the flap in the closed position. Advantageously, the flap is integrally molded with the pushbutton 3 or at least with a portion of the pushbutton. The cover may be molded with a line 28 of reduced thickness so that the plastic constitutes a hinge with the flap being urged resiliently outwards when the studs 26 and 27 are not engaged in the orifices of the channels. If the channels ~ ................................... . - . .
h ~ ~ ~ 3 3 2 meet inside the head of the pushbutton in order to mix the substances before they reach the open air, then there is only one outlet orifice, and the flap is provided with only one stud.
