Definitions

• the present invention relates to a dispenser of chemically unstable products which result from the mixture of at least two liquid components.
• both the balanced dosage and the homogeneous mixture of the components are difficult to obtain, because their respective sampling devices are independent.
• the present invention aims to solve these technical problems satisfactorily.
• a dispenser characterized in that it comprises an external housing containing at least two hermetic compartments each containing a liquid or pasty component, and provided with withdrawal members capable of be actuated simultaneously and jointly by a single push button and deliver into separate evacuation conduits formed inside said push button and opening out through at least one ejection orifice.
• each of said compartments is delimited, transversely, by the bottom of the external casing and by an internal bush for supporting the sampling member and, laterally, by the wall of an internal tubular element whose ends are fixed sealingly respectively to said socket and to the bottom of said housing.
• the tubular elements of each compartment are joined by a dividing partition.
• the wall of the internal tubular element forms a jacket at least partially in contact with the wall of the external housing.
• the wall of the internal tubular element is provided with a transverse shoulder allowing remote fixing of the wall of the external housing.
• the tubular element has a neck intended to receive the internal support bush for a sampling member.
• the tubular elements of each compartment are housed in a single housing.
• said evacuation conduits open to the outside via a common terminal portion.
• the ejection orifice is produced on a protruding boss on the lateral face of the push button.
• the dispenser of the invention can be used with withdrawal members in the form of a pump and / or valve and without it being necessary to provide seals.
• the dosing of the components is carried out in a simple manner, by adapting the respective capacity of the sampling means to the weight ratio of each of these components in the final product.
• the dispenser of the invention makes it possible to have, with a single packaging, which can be produced in various capacities, a simple, reliable and effective means for restoring an unstable bi or more generally multicomponent product.
• the dispenser of the invention can be manufactured industrially in a simple, rapid and economical manner, for example, by performing an injection molding of polypropylene.
• Figures 2A and 2B show sectional views of the embodiment of Figures 1A and 1B respectively in the rest phase and in the distribution phase;
• FIG. 5A, 5B and 5C show views respectively from below, in section along AA and in section along BB of the push button used for the dispenser of the invention.
• the dispenser shown in the figures is intended to condition and restore liquid and / or pasty components capable of forming, by mixing, a chemically unstable product qualified as extemporaneous preparation.
• This dispenser comprises, as shown in FIGS. 1A and 2A, an external housing 1 containing at least two, and here, exactly two hermetic compartments 11, 12 each containing a given volume of a determined liquid component.
• Each compartment 11, 12 is provided with a member 2 for removing the component contained therein.
• the sampling organs 2 here consist of pumps
• these members would then be formed of valves.
• the withdrawal members 2 are capable of being actuated simultaneously and jointly by a single push button 3, produced in a single piece and here covering the respective nozzle tubes 21a, 22a of the pumps 21,22.
• Pressing the push button 3 causes the liquid components to escape from their respective compartments and to be evacuated by separate conduits 31, 32 opening to the outside via at least one and preferably two ejection orifices 31a, 32a formed here on a boss 30 projecting from the lateral face of the push-button 3.
• the evacuation conduits 31, 32 open out, if necessary, via a common terminal portion 33 participating in the premixing of the components.
• Each of the compartments is delimited, transversely, by the bottom 10 of the housing 1 and by an internal bush 41,42 for supporting the sampling members and, laterally, by the wall of an internal tubular element 51,52.
• the ends of the tubular elements are fixed respectively to the socket 41, 42 and to the bottom 10 of the housing 1.
• tubular elements 51, 52 associated with each of the compartments 11, 12 are both housed in a single casing 5.
• connection between the bottom 10 and the lower edge of the tubular elements is preferably carried out by means of a flat weld
• connection between the tubular elements 51, 52 and the sockets 41, 42 is carried out, in the modes shown in FIGS. 2A and 3A, by fitting of facing spans with tight radial tightening.
• the tubular elements are provided with a cylindrical neck 53 intended to receive the sockets.
• the sockets 41, 42 have a peripheral skirt 41a, 42a intended to be fitted outwardly on the neck 53 and delimiting in its upper part, an inner groove 41b, 42b also peripheral which covers the upper edge of the neck 53.
• the skirt 41a, 42a is extended by a flange 41c, 42c shown respectively in FIGS. 2A, 3A according to two distinct variant embodiments, and intended to trap the upper part of the body of the pumps 21,22.
• the sockets 41, 42 are produced in the extension of the tubular elements 51, 52 and in one piece with the latter.
• the sockets 41,42 thus directly delimit in their upper part cylindrical necks 53 which serve to support the bodies of the pumps 21,22.
• the wall of the tubular elements 51, 52 forms under the neck 53 a jacket at least partially in contact with the internal wall of the housing 1, ensuring, if necessary, a slight radial tightening.
• the introduction of the tubular elements into the housing 1 is then carried out by axial sliding.
• the side wall of the tubular elements 51, 52 is extended at the top by a transverse shoulder 54 extending radially outward to come into contact with the internal wall of the housing 1, forming spacer so as to allow positioning and remote fixing of this wall.
• the push button 3 shown in FIGS. 5A, 5B and 5C is produced here in the form of a cover inside of which are arranged sleeves 34 which come to fit on the external end of the nozzle tubes of the pumps 21, 22 and communicating laterally with the evacuation conduits 31,32.
• the upper face of the push button 3 is provided with a cavity 35 facilitating manual support.
• the lower part of the push-button 3 is engaged at rest, inside the upper part of the housing 1 (as shown in FIGS. 1, 2A, and 3B where it moves during manual support actuating the pumps 21 , 22 (see Figure 2B).
