Abstract

Device for releasing doses of matl. which will flow from a reservoir, such as a liq. soap dispenser, uses a subsidiary dose chamber made of matl. which allows flexible elastic walls to be integrated with a supporting flange or body which is essentially rigid because of differences in wall thickness. The dose chamber has a bowl profile, the base of which can be inflected by an external lever to a degree limited by an internal adjustable stop. Designed to minimise the number of components, joints and seals and associated fabrication/assembly/maintenance costs, esp. for containing fugitive chemicals such as wetting agent mixt. incorporating terpinol, phenol, alcohol or sundry esters. Examples quoted use dose chambers made of polypropylene or of polychloropene rubber, a coaxial outlet adaptor pref. also made of or having an interfacial seal of polychloroprene rubber and serving to engage an external operating lever comprising a polyamide moulding. The dose chamber may be integrated with a main reservoir body made of identical matl. or may be clamped into a body of relatively rigid matl. The connection between the main reservoir and the dose chamber pref. includes an elastic flap valve with an integral hinge. The main reservoir may discharge similar to different reagents through two or more dose chambers actuated by common or separate lever systems.

Description

 The present invention relates to wall dispensers for dispensing doses of a product liable to flow.

 Such devices usually combine, with a metering device, a reservoir containing, for example, a fungible product intended for bodily use. They use a large number of constituent parts to which are added assembly members, such as: screws, nuts, rivets, etc ... which are opposed to rapid assembly. The dosing deans are often complicated, therefore expensive, and made princspalevent from cylinders and pistons provided with seals cooperating with each other so as to form capacities i variable volume by relative displacement of these members with one another, as described in the patents FRANCE Nos 1140924 and its additive 910710 (origin Grande- 3retagne) - 2028651 2131415 (origin Germany) - 749691 and 937504 (Grande-3retagne) 291777 (Switzerland) - 7200925 (Holland).

 Other devices use simpler dosing means, using elastically deformable materials as described in the ERRANCE patents Nos: 2340074 (Italte) - 2420325 (Sweden) 1 where the devices deliver doses whose volume is not not adjustable or aldatory.

 A large number of these devices also use special technical means which favor disassembly (at least partially) in order to easily replace the sandy parts of the metering elements, which clearly demonstrates a lack of reliability, these means removing the codt clean appliances increased maintenance costs.

 Some of them leak, stain or soil the place above which they are installed, their ejector members not having or losing their tightness as a result of repeated operations. They avoid rowding.

 Other distributors are fitted out to receive exclusively a certain type of packaging for the renewal of the fungible product, such as the FRANCE Nos patents: 2340074 (Itelie) - 2028651 - 213144t5 (AllnGagne) - 7200925 (Holland). These devices do not respect the freedom of the consumer and cut off competition between them.

 The present invention proposes to overcome all of these drawbacks.

 Its object is to obtain, by injection molding, a good wall-mounted device for dispensing doses of therioplastic material according to two embodiments.

 The means of satisfying the first mode, which is the preferred one according to the invention, is to produce the dose dispensing device with thernoplastic hairs which, by reduction in specific places of their thickness, acquire flexibility or exceptional folding.

Regarding the use of Polypropylene for example, the Company
ATO informs that laboratory tests on 7 x 107 folds did not reveal any alteration of the material.

 The mechanical characteristics, combined with the chemical inertness of these materials, allow the production of a dose dispensing device provided with its dosing means, its closing means, means allowing the ease of positioning of maneuver for example, all done in a single mold on an injection molding machine. This is obviously a way to considerably lower its cost price, while providing it with incomparable reliability, eliminating seals, complex assemblies, etc.

 The metering means is obtained by varying, by deformation of the wall, without elongation at the temperatures and pressures considered, the volume of a capacity in the form, for example: of spherical segment with two bases, volvaceous, truncated cynic, anerorde, sinkhole , etc ... deformation caused by a stork (bent lever) not secured to the wall, by manufacturing or fixing.

 This capacity, in addition to relating to the external environment, has on its small perpendicular base and axially disposed outside a cylindrical appendage, provided with a central channel totally or partially drilled. In the latter case, the connection with the outside is established by means of one or more holes radially arranged in relation to the central channel.

 This appendage is not provided during the manufacture of a device capable of establishing or interrupting the flow of a product, but of a means added in the form of an elastically deformable cylindrical membrane which encloses the appendage, closing off the radial holes and opposing the flow of the product when the latter is only subjected to hydrostatic forces of thrusts at atmospheric pressure. The cooperation of the membrane and the appendix is the means of producing the ejection valve.

When the appendix is completely pierced axially, the membrane is arranged at its distal part in the form of a wet lip seal.

 The open part of the container opposite the appendix, or large base secured externally to the bottom of the tank, is closed peripherally inside, in a leaktight manner, by a circular shutter which defines the volume of the container.

 The latter is provided with means which make it possible to establish or unambiguously interrupt communication with the interior of the tank.

In addition, it is provided with a. means which makes it possible to adjust the volume of the dose of the product dispensed, by adjusting the deformation imposed on the wall of the capacity.

 The other embodiment differs from the previous one due to the partial choice of different materials. In fact, many materials lack or are insufficiently capable of flexibility or folding, while chemically having excellent behavior towards the various components entering into the products to be dispensed. These thermoplastic materials may, for example, be perfectly suitable for the production of the reservoir, the deformable devices being manufactured with suitable materials, separately, and put in place by means provided for this purpose.

 The dispensing devices produced according to the invention are exceptionally robust and reliable. They can function normally, without maintenance, which authorizes their employment as well in the general public domain as that of the communities.

 To satisfy particular users whose family sanitary facilities include double bodily care stations (double sink), a dispensing device with two gilding devices can be produced. If a sealed wall separates the two devices, different products can be dosed; these, more especially reserved for each of the sexes, for example (detergents or emollients, neutral or perfumed products).

 For communities, corporate restaurant sinks for example, this allows from a single location to double the flow of a device, promoting user circulation, it being understood that the volume of the tanks may be greater than that intended for use by the general public.

 These dispensing devices will be manufactured according to the principles previously explained.

Other characteristics and advantages will emerge more clearly on reading the following description made with reference to the appended diagrammatic drawings showing, by way of nonlimiting example, a torve of realization where the figures represent

 Figure 1 shows a perspective view intended to illustrate a possible aspect of the device, which can between treated according to the laws of the pregnance of forms, provided with a single metering device made of thermoplastic material by injection. It shows the reservoir 1, its closing means 2 provided with the sides 3, the front face 4 of which is forgotten, serves for gripping and the rear of which is provided with a hinge 5.

 An indicator light 6, located at the base of the lifting face 7 of the apparatus, makes it possible to ensure that it is supplied with product delivered in doses under the action of the stork 8 which is urged at will in the direction of the arrow 9.

 Figure 2 shows the device in section along li of fig. 1, where we see the tank 1 provided with holes - shown diagrammatically by the axis lines 10 which serve to fix the device vertically on a wall shown in broken lines there - which cooperate with fixing members not shown. The tank 1 is closed at aa upper part by the cover 2 which is not airtight, the cities 3 of which fit together; for example, the top of the tank 1. The cover 2 is articulated on the tank 1 by a zone of locally thinned material 5, which behaves analogously like the joints of arthropods where the chitin thinning allows the movement of the segments.

 Inside the cover 2, a circular zone of lesser resistance 12 is arranged (visible in fig. 3) which it may be sufficient to trepan with a STANLEY type knife to generate a hole into which the body of a lock k is introduced. barrel 13 provided with a rotating pin 14 which enters an opening 15 arranged in the face 7, the housing preventing access to the interior of the apparatus (this possibility only finds its usefulness when the apparatus is used in public places. This detail arranged on an imprint allows this duality of user). The interior of the closed lid 2 comes into abutment on the portion 16 of the reservoir 1. The forged portion 4 of the lid has an internal plunge in the form of tabs 17 which resiliently come, when the lid is closed, to be housed in the internal lateral parts extracted from the opening 15. Their position is such that it does not encroach on the arc of the sector swept by the pin 14 of the lock 13 during its operation. The top of the reserve cover prefers to injure a flat area 19 favoring the mounting of the lock 13 held by a clip. As known, the top of the cover can be arranged to serve as ring holder or ashtray support.

 it is obvious that this closing means could have been embolished instead of floating, or even arranged by a rebate system practiced on the thickness of the walls of the device; which contributes to aesthetic changes.

 The sight glass 6 of translucent, or preferably transparent material, is axially installed parallel and at a certain distance from the bottom of the tank 1, indicating the level 20 (shown in dashed lines) of the product remaining contained in the apparatus and which constitutes a "reserve waiting time "to allow recharging of the device, avoiding an interruption in the supply.

 The mounting of the sight glass 6 is done from the inside of the tank 1, for example, using a male hexagonal ratchet wrench, these entering 11 adapted recess 22 of the sight glass 6. The tightness with the wall 7 is obtained by forcibly screwing the sight glass 6 provided with a fine pitch thread 21 of taper 6.25 ffi (1/16).

 The hardness ratio between the two materials, the play of tolerances, the pitch of the thread, make it possible to envisage this simple assembly whose effectiveness is well known. To avoid disturbing the operator performing the assembly, the threading can be carried out on the left.

 pu side opposite to the sight glass, are arranged in parallel two gussets 23 each provided with two acutangular zones 25 making it possible to pierce the operculum of a refill 27 (partially represented in broken lines in fig.). The two acutangular zones 25 are placed at such a distance from each other that the tearing of the cover generally produced with an aluminum film coated with a heat-fusible lacquer - generates a large opening. The neck 28 of the refill rests on the rectilinear parts 29 of the gussets 23 promoting its draining. The gussets 23 stiffen the bottom 31 with the back of the device. These are extended by two ribs 33 whose sonnets 34 serve as an indication of limit level when the device is supplied with a bulk product. Furthermore, the gussets 23 oppose the resulting forces transmitted by the walls 37 of the chappe located practically in their extension. These forces are generated by the stork 8 (seen in FIG. 2) when it is possibly abnormally stressed in the direction of the arrow 9. These maximum forces appear after variation of the shape of the capacity 41, at the time of the end. 39 of the stork 8 - by means of the inner face of the small base 40 of the capacity 41 in compression - comes into contact on the face of the volumetric adjustment screw 42, the stork 8 pivoting suggested because of the pins shouldered 43 with which it is provided, free to rotate in the holes 45 (visible in FIG. 3.) provided for this purpose in the walls 37 of the chappe.

 The extract 39 of the stork 8 is provided with a hole 47 intended to favor the passage of the ejection valve with which the variable volume capacity 41 is provided, in the form of a spherical segment with two bases. The hole 47 is of such size and shape that it guides the ejection valve without disturbing its operation due to the small angular movement of the stork 8.

 The ejection valve is made by an axial appendage 48, perpendicular and integral with the small base 40 of the capacity 41, for a view of a blind axial bore 49 opening inside the capacity 41 and outside by orifices 50, for example radially arranged. These are closed off externally by a tubular membrane 52 elastically enclosing the appendage 48. This thin membrane 52, made for example of Chloroprene 50/60 shores, is provided at one end with a circular external shoulder 53 whose external face comes tackle on. the outer face of the small base 40 of the variable volume capacity 41. A superimposed washer 55, made of stainless steel or polyamide for example, is intended to reduce attrition by lowering the angle of the friction tangent.

 The membrane 52, due to its shoulder 53 and the washer 55, is trapped between the external face 40 of the capacity 41 and the top of the end 39 of the stork 8. The structure of the capacity 41 gives it a memory (added to the molecular memory) all the more constant, that the imposed strain is weak and not pernanent; which excludes any hysteresis.

 At the end of the request for the capacity 41, the latter returns to its initial position and drives the stork 8 to its point of origin. The thickness of the wall of uniform or variable capacity increases or reduces its resistance to deformation, and by the same token the restored force, or nerve. In the case of a choice of structure reducing the nerve, a helical compression spring 57 can overcome this drawback.

 The return of the stork 8 to its initial position is invariable, due to the stops 59 with which it is provided which come into contact with the flat faces 60 of the walls 37 of the cap, reserving a space between the wall 11 and the end 62 stork 8 whose digital grip is favored by the shape of its end.

In this device version; the capacity 41 is molded with the bottom 31 of the tank 1, eliminating with certainty the leaks; these occur all the more easily, as the product to be distributed surfactant has wetting properties further improved by additives such as: Terpineol, Phenol, Alcohol, Esther
Between the bottom 91 of the reservoir 1 and the capacity 41, a thread 63 - formed in the wall of a recess 64 provided with an internal shoulder 65 - makes it possible to screw a shutter 66 provided. of an external thread 67. The face of this obturator comes to bear on the internal face of the shoulder 65 by means of a circular joint, preferably hemicylindric rence 68 (toric, cut in the median plane). I1 is provided in its center with the adjusting screw 42, and at least one unequivocal valve 69 authorizing only the admission of the product contained in the reservoir 1 and opposing its discharge during the pressure increase in capacity 41 when the dose is ejected.

 The variable volume capacity 41 of the product to be dosed is supplied by the orifice 70 situated opposite the valve 69. A recess 71 is arranged to receive the possible spring 57.

 We refer to fig. 3.- This represents the main part in section along li of fig. 1, and essentially shows: the tank 1 provided with its cover 2; the gussets 23; the walls of the cap 37; the chamfered hole 73 into which the sight glass 6 is inserted.

 The cover of the device half-opened, shows the closing tabs 17 intended to cooperate with the opening 15 arranged in the face 7 of the tank 1.

 It also shows the circular U-shaped or V-shaped imprint 74 made on the inside and in the thickness of the cover and intended to promote the trepanning necessary for the possible introduction of the barrel of the lock 13 (the other references designate the mOles organs as in fig. 2).

 Below the joint 5 of the closure means 2, mortises 75 are provided to receive the pins 76 (fig. 8) of a cover produced separately. The tools are provided to contribute to this result, by local replacement or substitution of a device.

 This figure also shows the inlets 77 made on the internal faces of the walls 37 of the cap intended to promote the introduction of the stork 8 by bending the walls.

To favor the manufacture of the tank and allow a simple demolding by reducing the mechanization of the mold, the cover can In addition folded down along the back of the device to 2700 compared to the opening of the tank (in broken lines in fig .)
it is obvious, that the object must title without welding, principally at the places where the material is requested to carry out movements.

 The closing of the tank by its cover, quickly after it is removed from the mold, can avoid the possible catenary effect that can take place on flat walls of a certain height.

 We refer to fig. 4.- This represents the underside of the device seen according to F in FIG. 3, the cover 2 closing the tank 1 and showing the arrangement of the walls 37 of the cnSppe and of the inlets 77 intended to guide the pins 43 of the stork 8 (fig. 7).

 It also shows, from the front, the appendage 48 and a partial cutaway which unmasks a local section of the opening 15 into which the cleats 17 are penetrated. The internal gussets 23 provided with their acutangular zones 25, are shown in broken lines .

We refer to fig. 5.- the use of a material, rigid for example, was chosen for the manufacture of the tank 1A
It represents a section, along li of FIG. t, (reduced from the lower part of the device) which shows 3. 'arrangement intended to receive a removable variable volume capacity (fig. 12 for example), produced separately and in a different material from that of the tank rA of which the large base is provided with an outer collar 87 (fig. 12), which is retained by the internal shoulder 65 of the chamber 64. The advantage of this type of fabrication is that it can be called transparent or translucent materials and possibly tinted (in this case, the indicator is no longer useful); which increases the aesthetic diversity of the device.

 We refer to fig. 6 & 7, which show the stork 8 produced by molding, in Polyamide fv Pa 66 for example, provided on each of its sides with its shouldered pins 43 and stops 59. A partial section of the e - treaty 39 of the stork 8, shows the hole 47-which can title provided with a skirt 47 A fig. 6 - reserved for the passage of the ejection valve. We also see in this figure, the means 62 favoring the digital grip of the stork 8 by hand in supination.

 We refer to fig. 8, which shows a means of closing. removable 2A from the tank 1 A. produced separately and whose fixing at the rear is ensured by a system of mortises 75 and tenons 76. Stoppers 79 allow the closing tabs 17 to accomplish their function by avoiding the recoil of the cover . As previously described, this cover can between provided with a lock.

 We refer to fig. 9.- This represents, seen from below, the circular shutter 66 provided on its periphery with a thread 67 intended to ensure its fixing with the tank end 31, fig. 2 or 31 A fig. 5, tapped at its center 80 to receive an adjustment screw 42. A recess 71 serves to center a possible spring 57 (fig. 2).

 This figure shows the inlet valve 69 located opposite the supply orifice 70. Ribs 81, located between the lightening intervals 82, serve as coaches when the circular shutter 66 is screwed into the bottom 31 or 31 A of the tank 1 or t A (fig. 2 or 5). A circular seal 68 of semi-cylindrical section preferably, forms an integral part of the shutter 66 and ensures its tightness with the bottom 31 of the dispenser. When mounting the shutter 66 in the bottom 31A of the tank lA fig. 5, the seal 68 also assumes the tight fixing of the variable volume capacity, cbjet of figs. 12 and 13 for example.

We refer to fig. 10, which represents the shutter 66, seen in
section, according to AAfig. 9. The mime markers designate the same elements as in FIG. 9.

We refer to fig. 11, which shows in enlarged half-section the right part of FIG. 9. This shows in more detail the semicylindrical circular seal 68, the projection of which is preferably slightly set back relative to the closing plane of the valve 69, for manufacturing reasons explained below.
The valve 69 is produced by the partial sectioning, along arrow F, of a hollow boss projecting from the face 83 of the shutter 66.

The hollow of the boss is made by the penetration of the pin reserving the orifice 70.

 The sectioning, without removal of material, is preferably carried out between the face 83 of the shutter and the bottom 84 of the valve. This valve can open from the angle cc to relate the tank and the capacity through channel 70.

 The importance of the sectioning conditions the opening oc of the valve 69 and determines the nerve "of said valve, which keeps it resiliently closed, thus making a valve with automatic closure.

 We refer to fig. 12.- This represents, in section, a removable volvaceous, deformable 85 capacity, which can be installed in the bottom of the tank of a device made of a rigid material, for example 1 A fig. 5. It is provided with the cdté of the large base 86, with a peripheral external shoulder 87 and, on the contrary, with a hollow appendage 88 externally and axially arranged, allowing it to communicate with the external environment. The distal part of the appendage 88 is arranged in the form of a wet lip seal 89. It can, for example, be made in a material, such as Chloroprene 50/60 shores, for example.

 We refer to fig. 13, which clearly shows, seen from below along F of FIG. 12, the wet lip seal 89.

 We refer to fig. 14, which represents, in section, a removable conical deformable capacity truncated straight with steps 90, provided with a collar 91 outside its large base. Solidly with its small base 92, a hollow appendage 93 opens onto the external environment through radial orifices 94. This capacity may be made of a material, such as polypropylene, for example.

 We refer to fig. 15.- This represents in section, the membrane acting as an external valve, mentioned in the description in fig. 2. We can clearly see the circular shoulder 53, and the elastically deformable cylindrical membrane 52 responsible for closing the orifices 50 fig. 2 cu 94 fig. 14.

 We refer to fig. 16, which shows, view from below along F of FIG. 17, another form of removable deformable capacity truncated conical straight stepped, provided with a shoulder 95 outside its large base and an appendage 96 integral with the small base 97 pierced with an axial channel 98 which connects the capacity inside with the outside environment.

 We refer to fig. 17, which shows, in section, the capacity of FIG. 16. The same references designate the same elements.

 We refer to fig. 18, which shows, in section, a membrane of elastically deformable material intended to cooperate with hollow appendages, as described in fig. 16 and 17. It is arranged so as to have an external circular shoulder 99 secured to a tubular part ioe.

It is provided at its distal part with a seal with 'wet lips '01. This consists of two flat lips, elastic tight against one another in a sealed manner, which open soua the effect of the pressure su produced from the variable volume capacity, for example fig. 16, and oppose after their closure any air intake.

 Operation. we refer to fig. 2.

 After filling of the reservoir 1 u suitably installed distributor, the primed apparatus, the stress on the stork 8 generates the forces necessary to cause the mechanical deformation of the scarcity of the capacity 41, and consequently the increase in the pressure of the product contained in said capacity which assists the valve 69 during the closing of the supply orifice 7C which pockets any discharge of the product into the tank. When the pressure forces of the product to be dispensed are greater than the resistant elastic forces of the wall 52 of the membrane which encloses the appendage 48, the product is forced to escape through the orifices 5t by locally pushing the elastic wall 52 which s temporarily gobs.

 As soon as the forces of ression disappear, the membrane returns to its initial shape by sealing the orifices 5O, expelling the residual product while avoiding with certainty the stillation.

 Kn possession of the dose, the user ceases to operate the stork 8 which returns to its place driven, by the return of its deformable capacity, to its original position. This return creates a vexent vacuum inside which forces the valve 69 to unmask the orifice 70, letting the product contained in the tank t penetrate into the capacity 41 which it fills.

 This device is advantageously used, both for private use as communities (corporate restaurants, hospitals ...) or public places (airports, hotels ...).

The invention is in no way limited to the embodiments described.

 Cn can make modifications to it: shape, combinations, material, without departing from the scope of the invention; the medium dosing zones can be adapted to different forms of fixed or movable containers.
