Definitions

  • the present invention relates to a device allowing operation, both in the inverted position and in upright position, of a fluid dispenser generally comprising a fluid reservoir and a dispensing member, such as a pump or a valve.
  • a fluid dispenser generally comprising a fluid reservoir and a dispensing member, such as a pump or a valve.
  • the distributor includes generally a dip tube mounted on the inlet of the distribution and extending towards the bottom of the tank.
  • the present invention therefore relates to a device allowing the operation of such a conventional dispenser even in the inverted position.
  • Such operating devices in position are known from the prior art, and in particular from document FR-2 627 708 which describes a device to be mounted between the dip tube and the inlet of the pump or valve.
  • the device comprises two inputs, each provided with a ball valve.
  • the balls are metallic balls which are stressed by gravity on their valve seat respective. In the upright position, the ball of one of the two valves rests tightly on its valve seat, which prevents the ingress of air in the distributor. AT conversely, when the distributor is in position overturned, the ball of the other valve rests on its seat respective valve and also prevents the entry of air in the dispenser.
  • This device therefore puts in works two valves requested by gravity to close selectively an input communicating with the tank. he however, it should be noted that the design of such a device is relatively complicated because each ball has to be housed in a delimited space in which it is prisoner. Such a design requires the implementation work of at least three pieces whose assembly is very complicated.
  • the object of the present invention is to remedy the disadvantages of the prior art cited by defining a other device whose number of components is reduced to a minimum and whose assembly is very simple.
  • the present invention provides a device for operation, both in inverted position than in an upright position, a distributor of fluid product comprising a fluid reservoir, and a distribution member, such as a pump or a valve, with an inlet and a dip tube extending into the tank, said device being disposed between the inlet of the dispensing member and the dip tube, said device comprises a chamber in communication with said entrance to the distribution unit, said chamber including two selectively high and low inputs can be closed by respective top and bottom valves in depending on the upside-down or right position of the dispenser, the high valve comprising a suitable movable valve element to close the upper entrance to the chamber in the straight position, characterized in that the bottom valve includes a floating floating valve with a density lower than that of the fluid suitable for closing the lower entrance to the chamber in the inverted position when the chamber is filled with fluid product.
  • the bottom valve does not work not by gravity to close the lower entrance to the room but thanks to Archimedes' push due to its density lower than that of the fluid to be dispensed. We can so use a ball in this valve element plastic material.
  • the top valve element has a density greater than that of the fluid product.
  • the high valve element consists of a flyweight stressed by gravity, although submerged, on a valve seat high in upright position.
  • the counterweight consists of a metallic cylindrical sleeve of which a lower end is adapted to come into contact watertight with the valve seat high in the upright position.
  • the device can consist of a body and an internal sleeve fitted in said body, the tube plunger being mounted on the body and the inner sleeve being attached to the inlet of the dispensing member, the body forming the low entry and the socket the high entry, the chamber being formed between the body and the socket.
  • the upper entry in the internal socket is defined by at least one passage opening whose edges form the high valve seat on which the end bottom of the metallic cylindrical sleeve comes in tight contact in right position.
  • the internal sleeve defines an output channel of the communicating room with the entry of the distribution member, said channel exit from the chamber with a profiled mouth of so as to prevent the said element from blocking said channel floating bottom valve.
  • the low valve seat is defined by the body as a surface frusto-conical flaring upwards in an upright position. So that the device of the prior art described above puts using at least three constituent parts, it is possible to make the device according to the invention with two pieces only because the top valve element mobile is limited in its movement by the distribution.
  • the device chosen to illustrate this invention and shown in Figures 1 and 2 includes four component parts, namely two fixed parts and two moving parts. Compared to the art device previously described, this is an advantage important.
  • the two fixed parts are made up of a body substantially cylindrical 1 and an internal sleeve 2. These two pieces can be molded in plastic.
  • the body 1 is a hollow part formed by an upper cylinder 11 which extends at its lower end with a shoulder re-entering 12 from which part extends downwards frustoconical 13 which is extended by an end cylinder lower 14.
  • the body 1 therefore forms an inner shoulder 12 which defines an annular bearing surface.
  • the part tapered 13 internally defines a surface frustoconical which serves as a valve seat as we will see below.
  • the lower cylinder 14 serves as a sleeve for connection for fitting a dip tube 16.
  • the internal sleeve 2 consists of a hollow rod 21 at the lower end of which is connected a annular flange 22 which projects outwards.
  • the internal sleeve 2 thus defines an outlet channel 28.
  • the internal sleeve 2 is arranged inside the body 1 with the annular collar 22 resting on the shoulder 12.
  • This annular flange 22 fills many functions in addition to that of support in the body 1. All first, it defines with the frustoconical part 13 of the body 1 a room 15 inside which is housed a floating ball 3 for example made of plastic. When the device is in the straight position as shown in Figure 1, the ball 3 rests on its seat valve 13 without sealing, or at least not sealing perfect.
  • the floating ball 3 is also in tight contact with the frustoconical seat 13 and thus closes the low inlet to the dip tube because that the ball has a density lower than that of liquid.
  • the valve member of the present invention which allows selectively block the low input of the device towards the dip tube 16 consists of a ball preferably in plastic that floats when submerged in liquid due to of Archimedes' push. Therefore, when the device is in an upright position as shown in FIG.
  • the floating ball 3 is lifted from its seat frustoconical 13 on the one hand because it is driven by the rising flow of liquid and secondly the fact that it floats in the presence of liquid.
  • the fluid can therefore penetrate inside room 15 through the low entrance and flow from there through the outlet channel 28 formed at the inside of the rod 21 of the internal sleeve 2.
  • the inner sleeve 2 has the function 2 of delimit a space which forms a chamber 15 in which a floating ball 3 is trapped.
  • the annular collar 2 Another function of the annular collar 2 is to define a high input 25 which also communicates room 15 with the outside.
  • the high entry 25 is formed of several distributed passage openings circumferentially in the annular flange 22.
  • the 25 passage openings extend from the surface upper ring of the flange 22 downwards where they join radial grooves 26 which aim to guarantee a passage for the fluid when the ball floating 3 is pressed against the annular flange 22 as shown in figure 1.
  • this element movable valve consists of a cylindrical sleeve 4 which has a density greater than that of the fluid.
  • this cylindrical sleeve 4 is made of metal, for example steel.
  • the cylindrical metal sleeve 4 is arranged inside the upper cylinder 11 of the body 1 and concentrically around the rod 21 of the internal sleeve 2. It has a lower end 41 shaped to suit the shape of the seat 27 formed by the flange 22 of the internal sleeve 2.
  • the device according to the invention is shown mounted on a distribution member such than a pump or a valve and which is designated by the reference numeral 5 in the figures, whether it is a pump or a valve, this consists of a body of pump or valve 51 of which only the lower end has been shown in the figures.
  • the pump or valve forms a frustoconical valve seat 52 in which is housed a low valve ball 54 for example constituted of steel.
  • the body 51 forms a connection sleeve 57 which is normally adapted to the reception of a classic dip tube. This constitutes a completely classic design of a pump or valve in its lower area; the bottom valve ball 54 closing the inlet 55 of the pump or valve chamber formed by the body 51.
  • connection of the operating device in the inverted position is connects to the sleeve 57 via the rod 21 which takes the place of the classic dip tube normally inserted.
  • the rod 21 can advantageously be adapted by length so that when fully seated inside the sleeve 57, the lower end of the connection sleeve 57 abuts on the surface upper of the annular collar 22. It is essential for the invention that the internal diameter of the sleeve cylindrical metallic 4 is greater than the external diameter of the connection sleeve 57 of the body 51 so that the sleeve can move axially freely on a certain distance to allow selective opening of the upper entrance 25 of room 15.
  • displacement of the metallic cylindrical sleeve 4 is limited in height by the body 51 of the valve or of the pump 5.
  • the limitation of the displacement of the sleeve 4 is achieved by tapered part 52 of the body 51 internally forming the seat for the bottom valve ball 54.
  • the external surface 56 thus forms a stop surface against which the end upper part of the sleeve 42 abuts when the device is in its inverted position as shown in Figure 2. It is therefore not necessary that the device incorporates a particular additional room whose function is to define a stop surface for the metallic cylindrical sleeve 4. This saves a piece in the device.
  • the fluid product thus sucked off takes off the floating ball 3 from its seat 13 and the plate against the annular collar 22 in which are provided the passage grooves 26 which allow a communication between chamber 15 and outlet channel 28 which communicates with the entry 55 of the distribution unit.
  • the ball 54 of the inlet valve of the dispensing member is lifted from its seat 52 by the flow of fluid thus sucked up.
  • the ball 3 is floating which promotes its separation from the low valve seat 13.
  • the metallic cylindrical sleeve 4 leaves its seat 27 to come into abutment with its upper end 42 with the frustoconical wall 56 formed by the body 51 of the distribution member 5.
  • the upper entrance 25 of the chamber 15 is then opened. Because the distributor is in overturned position, the fluid is located in the vicinity of the distribution member and of the upper cylinder 11 of the device body. When a depression is created at inside the body of the dispensing member 5, this has for the effect of sucking fluid which follows a path as shown in Figure 2 by the arrows. The introduction of fluid inside chamber 15 has the effect of lifting the floating ball 3 which then presses tightly against its seat 13 as shown in FIG. 2. It is thus impossible to draw air through the dip tube 16 whose end is in the air.
  • the fluid product therefore passes between the upper end of the cylinder 11 and the body 51 of the dispensing member then between the sleeve 4 and the cylinder 11 then through the high entry 25 and the grooves passage 26 to reach the interior of the outlet 28 and finally penetrate inside the pump body by lifting the ball 54 from the bottom valve.
  • the floating ball 3 falls on the annular collar 22 of the inner sleeve 2.
  • this device consists of only four parts , two fixed and two mobile, including mounting is very simple since it is enough at first to place the floating ball 3 inside the body 1, then secondly insert the internal sleeve 2 inside the body 1, then finally come and place the cylindrical sleeve 4 around the sleeve 2 inside body 1.
