Definitions
- the present invention relates to a duo dispenser comprising two reservoirs, namely an external reservoir and an internal reservoir, as well as two pumps communicating respectively with the reservoirs.
- a common pushbutton allows both pumps to be activated simultaneously.
- the preferred field of application of the invention is that of cosmetics, but it can also be applied to pharmacy, drugstores or the food industry.
- the duo distributor of the invention comprises two pumps, and not a single mixing pump, so that the two pumps can be standard, with different or identical doses. Furthermore, the present invention seeks to simplify as much as possible the filling and assembly operations of the distributor and particularly the introduction of the dip tube of the external reservoir pump.
- the invention proposes that the internal reservoir comprises two separate parts, namely an external envelope and an internal sleeve which extends inside the external envelope, one of the pumps communicating with the external reservoir through this internal sleeve, the other pump communicating directly with the internal reservoir.
- the internal tank is placed inside the external tank.
- the internal sleeve defines a lower end which is in sealed contact with the external casing, this lower end opening directly into the external tank.
- the internal sleeve may comprise a body which terminates in the lower end, which is connected in a sealed manner in an opening in the external envelope by means of a sealing ring.
- the body can define at its upper end a mouth, the passage section of which is much larger than that of the lower end, the body advantageously having a general funnel-shaped configuration with a gradually decreasing passage section.
- the internal sleeve defines an internal space which communicates with the external reservoir.
- the internal space of the internal sleeve forms an extension of the external reservoir or that it is an integral part of the external reservoir.
- the external reservoir pump includes a dip tube which extends through the internal sleeve into the external reservoir.
- the dip tube can also be said to protrude beyond the inner sleeve into the outer tank.
- the dip tube soaks in the fluid product from the external reservoir which rises into the internal sleeve. There is no seal between the dip tube and the internal sleeve. Thus, it is easy to introduce the dip tube into the internal sleeve.
- the pump can also extend inside the internal sleeve.
- the internal sleeve can extend in an off-axis or eccentric manner inside the external envelope.
- the internal sleeve then does not have symmetry of revolution. This allows the dip tube to open into the external tank at the outlet of the internal sleeve centrally or axially in relation to the external tank, while the pump is mounted off-axis or offset.
- the internal sleeve forces the dip tube to bend.
- the lower end of the internal sleeve defines a minimum passage section.
- the upper end of the inner sleeve can define the maximum passage section to facilitate the insertion of the free end of the dip tube.
- the internal sleeve can then decrease in passage section up to its lower end.
- the internal sleeve can define an upper end which communicates with the external tank through a pressure balancing conduit, which advantageously forms an air bridge which spans the internal tank.
- the distributor may comprise a pump support forming two receiving housings respectively for the two pumps, one receiving housing communicating with the internal sleeve and the other receiving housing communicating with the internal reservoir, the pump support forming a main section of a pressure balancing conduit, which connects the internal sleeve to the external tank.
- the distributor may include a common seal which comes into sealing contact with both the external reservoir, the external casing and the internal sleeve.
- the common seal is compressed on the external tank, the external envelope and the internal sleeve by the pump support.
- the outer casing is supported by the external reservoir and the internal sleeve is supported by the outer casing.
- the spirit of the invention lies in extending the external tank inside the internal tank, so that the external tank extends both around and inside the internal tank, which can thus present an annular cross section.
- This extension of the external reservoir is formed by the internal space of the internal sleeve, which also forms the internal wall of the internal reservoir.
- the external tank and the internal sleeve together form a sort of concentric siphon, which communicates by fluid in the lower part, but also by air in the upper part through a pressure balancing or internal ventilation conduit. This ensures that the level of fluid product is the same in the external reservoir and in the internal sleeve.
- the design of the internal sleeve in the shape of a funnel or decreasing section is advantageous for the assembly of the dip tube, which is guided by the internal sleeve until it reaches the bottom of the external tank.
- Figure 1 is a perspective view of the duo distributor according to one embodiment of the invention.
- Figure 2 is a vertical cross-sectional view through a duo distributor of the invention along a vertical plane passing through the two pumps
- Figure 3 is a view similar to that of Figure 1 along a vertical plane perpendicular to that of Figure 1 and passing through the plane of the vent duct.
- the duo distributor comprises two tanks arranged one inside the other, namely an external tank R1 and an internal tank R2.
- the external tank R1 can be in the form of a shell comprising a side wall R11 of generally cylindrical shape, a bottom R12 allowing the distributor to be kept upright and a neck R13, possibly provided with hooking means.
- the neck R13 connects the side wall by two internal shoulders R14 and R15, which are arranged in concentric steps. Their functions will be given below.
- the external tank R1 can advantageously be made with a transparent material, in order to reveal its contents.
- the internal tank R2 is arranged inside the external tank R1.
- the reservoir R2 comprises an outer casing R21 and an internal sleeve R22 which extends inside the outer casing R21.
- the external envelope R21 comprises a barrel R211 of generally cylindrical shape, which is extended by a bottom R212 forming a central opening R213. At its upper end, the external envelope R21 forms an annular collar R214 which rests on the internal shoulder R14 of the external tank R1.
- the R211 barrel forms an internal shoulder R216 near the annular flange R214.
- the internal shoulder R14, the annular flange R214 and the internal shoulder R216 can be circular.
- the barrel R211 and the bottom R212 extend inside the external tank R1 with a distance separating them, so as to form a useful volume V1 in the shape of a bucket.
- the inner sleeve R22 comprises a body R220 which terminates in a lower end R222, which is sealed in the opening R213 by means of a sealing ring R23. At its upper end, the body R220 defines a mouth R224, the passage section of which is much larger than that of the lower end R222.
- the R220 body thus presents a configuration generally funnel-shaped with a gradually decreasing passage section.
- the body R220 defines two opposite walls R221 and R222, which are different: the wall R222 is straight and vertical, while the wall R221 is first straight and vertical from the mouth R224, then oblique and straight again at the lower end R222.
- the opposite walls of the body R220 are symmetrical and have a configuration similar to the wall R221, but with a less inclined oblique section.
- the mouth R224 is arranged eccentrically, off-axis or offset inside the neck R214.
- the lower end R222 is arranged in a perfectly axial or centered manner, so that the body R220 extends off-axis inside the external envelope R21.
- the internal sleeve R22 also defines a support ring R225, which extends around the mouth R224, but eccentrically.
- the R225 support crown forms a beach, which extends in the shape of a crescent moon around the R224 mouth. This range forms a passage opening R226, which gives direct access to the internal tank R2.
- the support ring R225 rests on the internal shoulder R216 of the external envelope R21.
- the support crown R225 can be circular, but the mouth R224 can have any shape, geometric or not.
- the external envelope R21 and the internal sleeve R22 define between them a useful volume V2.
- the sleeve R22 or more precisely its body R220, also defines an internal space E which communicates with the useful volume V1 through the lower end R222 of the internal sleeve R22.
- the external tank R1 thus defines a total useful volume which corresponds to the sum of the useful volume V1 and the internal space E.
- the useful volume V1 of the external tank R1 is extended to the interior of the internal sleeve R21 which defines the internal space E.
- the useful volume V1 and the internal space E are initially filled with a first fluid product F1, which therefore extends both around and inside the internal reservoir R2.
- this internal reservoir R2 it is initially filled with a second fluid product F2, which may be identical to the fluid product F1, or preferably different.
- the tank R1 can for example be half filled and the tank R2 can then be introduced into the partially filled tank R1. Then simply fill tank R2. Alternatively, it is possible to fill the tank R1 through the internal sleeve R22, then the tank R2.
- the duo distributor of the invention also comprises two pumps P1 and P2, the pump P1 being associated with the internal reservoir R1 and the pump P2 being associated with the internal reservoir R2.
- the pumps P1 and P2 can be identical, or preferably different, particularly in terms of their doses.
- the design of pumps P1 and P2 is not critical to the present invention, and will therefore not be described in detail.
- each pump P1, P2 comprises a pump body P11, P21, in which an actuating rod P12, P22 can be moved axially back and forth.
- the pumps P1, P2 also each include a dip tube P13, P23: the dip tube P13 extending inside the internal sleeve R22 and defines a lower end which is located near the bottom R12 of the external tank R1. As for the dip tube P23, it extends straight inside the internal tank R2 to close to the bottom R212.
- the dip tube P13 is slightly bent, due to the off-axis design of the internal sleeve R21, so as to position the lower end of the dip tube P13 substantially axial or central in relation to the bottom R12 of the external tank R1 .
- the funnel-shaped design of the R21 internal sleeve allows the lower end of the P13 dip tube to be easily engaged through the R224 mouthpiece.
- the body R220 which narrows then guides the dip tube P13 towards the lower end R223 and beyond into the external tank R1.
- the pump P1 is offset relative to the lower end R223 so that the dip tube P13 must undergo a deviation following the funnel shape of the internal sleeve R21.
- the duo distributor of the invention also comprises a pump support S which defines two receiving housings S1 and S2 respectively for the two pumps P1 and P2.
- the pump bodies P11 and P21 can for example be received by snapping into the receiving housings S1 and S2.
- the pump P1 can extend inside the mouth R224 of the internal sleeve R22 and the pump P2 can extend inside the outer casing R21 by passing through the passage opening R226 of the R225 support ring.
- a neck seal J is also provided, which is compressed on the internal shoulder R15 of the external tank R1, on the annular flange R214 of the external envelope R21, on the upper edge of the mouth R224 and on the support crown R225 of the internal sleeve R22.
- the compression of this neck joint J is ensured by the pump support S.
- the duo distributor also defines a pressure balancing conduit Q which communicates the internal space E of the internal sleeve R22 with the useful volume V1 of the external tank R1.
- the upper part of the tanks is not filled with fluid, but with air.
- the pressure balancing conduit Q makes it possible to communicate the air between the internal sleeve R22 and the external tank R1, so that the pressure is always identical in these two spaces. This results in the level of the fluid product F1 in the internal space E and in the useful volume V1 being identical.
- the pressure balancing conduit Q includes a main section S12, which extends horizontally through the support S, as well as two vertical sections J1 and J2, which are formed through the joint J.
- the pressure balancing conduit Q forms a sort of air bridge which spans the internal tank R2. This can be seen in Figure 3. We can thus say that the internal space E communicates with the useful volume V1 both in the lower part through the end R222 and in the upper part through the pressure balancing conduit S12.
- the pump support S is mounted on the neck R13 of the external tank R1 by means of a cover C which engages both the pump support S and the neck R13.
- the two actuating rods P12 and P22 are capped by a common pusher B, which defines a common outlet orifice B1.
- a common pusher B which defines a common outlet orifice B1.
- the pusher B is guided axially inside the cover C and the common outlet port B1 moves axially through a window C1 of the cover C, as can be seen in Figure 1. From the outside, the duo distributor only reveals the external tank R1, the cover C, the pusher B and the common outlet orifice B1.
- the external tank R1 is transparent, we also see the external casing R21 of the internal tank R2.
- the internal tank R2 is here produced by the sealed assembly of two parts, namely the external envelope R21 and the internal sleeve R22.
- This two-piece embodiment is explained by the fact that the internal sleeve R22 has a complex shape devoid of axis of symmetry.
- the body R220 of the internal sleeve R21 has axial symmetry, so as to be cylindrical. In this case, it could be considered to produce the external envelope R21 and the internal sleeve R22 in a single piece.
- the dip tube P13 is attached to the inlet of pump P1.
- the dip tube P13 is made in one piece or integral with the internal sleeve R22.
- the pump P1 would be fitted, during its assembly on the pump support S, in an end piece formed at the inlet of the dip tube.
- the external envelope R21 extends axially or centered inside the tank R1. Without leaving the framework of the invention, we can imagine other less symmetrical or central shapes for the external envelope R21.
- the internal sleeve thus defines a supplementary reservoir for the external reservoir and also makes it possible to receive the pump P1 in an off-axis manner while arranging the lower end P131 of the dip tube P13 in an axially central manner.
