Definitions
- the present invention relates to a pump and a container containing a liquid, for example a cosmetic cream, equipped with such a pump.
- a pump comprising a push button mounted on the move on a support subject to the container containing the product to distribute, the push button comprising a central cylindrical duct of revolution, provided with radial openings at its lower end, the support defining around this leads an annular pumping chamber, of variable volume.
- a membrane made in an elastomer is mounted on the support. This membrane has a part symmetrical center of revolution, in the form of a sleeve open at its upper end and closed at its lower end. The central duct of the push button is inserted in the membrane until it bears against the bottom of the sleeve.
- the membrane thus constitutes an elastic return member making it possible to return the push button to its initial position after dispensing a dose of product.
- the membrane by sticking to the central duct isolates the pumping chamber and avoids a re-entry of air into it.
- Such a pump has the advantage of having only a small number of parts and therefore to be relatively inexpensive to manufacture.
- the present invention aims to improve the reliability of the operation of a pump of the type defined above, namely comprising a movable member mounted at displacement relative to a support, the movable member comprising a central duct into which the product to be distributed enters through at least one opening, the support defining with the movable member, around said central duct, a variable volume pumping, this pump further comprising a membrane having a sleeve-shaped central part open at its upper end and closed at its lower end, central part into which said central duct is inserted, the membrane being arranged so as to isolate the opening or openings of said central duct allowing the entry of the product and the pumping chamber when the volume of the latter increases and product is drawn into the pumping chamber.
- At least one of the membrane and the duct central is shaped to prevent formation between the membrane and the central duct a sealed annular zone preventing the product contained in the pumping chamber to flow through said central duct when the volume of the pumping chamber decreases.
- At least one of the membrane and the central duct is shaped to bear against the other of the membrane and the central duct in predetermined locations of its periphery, at least during the relative displacement of the movable member and the support.
- At least one of the membrane and of the central duct comprises reliefs against which comes to bear the other of the membrane and the central duct, at less during the relative movement of the movable member and the support.
- said reliefs are produced on the membrane in preferably being constituted by bosses equi-distributed around the axis of the part center of the membrane at its opening.
- the membrane has a flexible lip capable on the one hand to isolate the pumping chamber from a source of product when the volume of said pumping chamber decreases and on the other hand to allow a return of product into said pumping chamber when the volume of the latter increases.
- said flexible lip is connected with said central part of the membrane by forming a narrow annular groove, open downwards, and the support has an inner skirt bearing at its upper end in the bottom of said groove, for axially retaining the membrane when the movable member is moved down to decrease the volume of the pumping chamber.
- the support has a double lip sealing, applying sealingly on a tubular skirt of the movable member, this tubular skirt being open downwards and extending around the central duct concentrically to the latter, this tubular skirt further delimiting radially towards outside the pumping chamber.
- the aforementioned inner skirt is part of a patch on the rest of the support.
- the aforementioned flexible lip has a rib annular by which it can be applied sealingly on the inner skirt of the support when the volume of the pumping chamber decreases or when the pump is at rest, said inner skirt communicating internally with the source of product and comprising above said annular rib openings allowing the product to gain the pumping chamber when the volume of the latter increases and that said flexible lip deviates from said inner skirt under the effect of the thrust of the product flowing to the pumping chamber.
- the flexible lip comprises, above said annular rib, a thinned area.
- the central duct of the movable member is provided, at its lower end, at least one radial opening.
- the movable member constitutes a push button, said central duct being produced in one piece with a dispensing nozzle.
- the tubular skirt of the movable member slides inside a support guide skirt, providing with said interior skirt of the support an annular groove open upwards, communicating by at least one orifice of air intake with the product source, the tubular skirt of the movable member applying sealingly on said guide skirt when the movable member is at rest and the volume of the pumping chamber is maximum.
- the pump includes a return spring for recall the movable organ to an initial position after the distribution of a dose of product.
- This return spring is advantageously constituted by a helical spring working in compression.
- This spring is preferably arranged in the axis of the membrane, so as to apply by its upper end to the lower end of the central part of the membrane.
- a return spring is advantageous because it facilitates the choice of the material which may constitute the membrane, since the latter may then not be or relatively weak prestress.
- the invention also relates to a container equipped with a pump such as defined above.
- FIG. 1 a container 1 having a body 2 forming reservoir, of which only the upper end is seen in the drawing, defining a neck 3 on which is snapped on a support 4.
- the support 4 guides in sliding, along an axis X, a push button 5 and used to mount a removable protective cover 6, covering the front push button 5 the first use.
- the support 4 includes a sealing skirt 7 which is applied in a sealed manner on the inside surface of the neck 3.
- the sealing skirt 7 is extended radially, on the one hand towards the outside by fixing lugs 8 snapped onto an annular bead 9 of the neck 3, and other goes inward by a stepped wall 10 defining a nozzle 12 used for connection of a dip tube 13, partially shown in the drawing.
- An outer skirt 15 and a guide skirt 16 are made in one piece by plastic molding with the sealing skirt 7, the fixing lugs 8 and the stepped wall 10.
- the outer skirt 15 extends around the neck 3 of the container and has a shoulder 17 on which the protective cover 6 is supported.
- the upper edge 18 of the outer skirt 15 retains the push button 5 at rest, as will be explained below.
- the support 4 comprises an inner skirt 20 constituted by a part added, having a lower end 21 shouldered, forcibly engaged in the stepped wall 10.
- the internal skirt 20 has a substantially tapered upper end, provided with openings 22, as can be seen more particularly in FIGS. 2 and 3.
- openings 22 are in the example described in the form of slots oriented along the X axis, extended downward by grooves 25 extending over the radially inner surface of the inner skirt 20 until a step 26.
- a double annular sealing lip 24 is produced in one piece with the inner skirt 20 by plastic molding.
- the push button 5 has an outer skirt 30, provided at its end lower of teeth 31, the latter abutting against the upper edge 18 of the skirt outside 15 of the support 4 when the push button 5 is at rest in the high position, as shown in figure 1.
- the push button 5 has a central duct 32, of axis X, and a skirt tubular 33 concentric, defining around the central duct 32 a pumping 34 annular.
- the outer skirt 30, the tubular skirt 33 and the central duct 32 are produced in one piece by molding plastic material with a dispensing nozzle 35, communicating internally with the central duct 32.
- the latter has, at its lower end, radial openings 36.
- the lower end of the tubular skirt 33 forms a sealing lip 37, extending slightly radially outward, as shown more particularly in Figure 4.
- the guide skirt 16 of the support 4 has a slight shrinkage in the lower part annular 41 on its radially inner surface.
- the interior of the container is thus isolated from the ambient air, which is favorable to good conservation of the product.
- An air intake orifice 42 is made in the bottom of this groove to allow air to re-enter the container as it is emptied.
- the inner skirt 20 is used for mounting a membrane 50 having a part central unit 51 in the form of a sleeve, axis X, open at its upper end and closed at its lower end by a bottom 52.
- This central part 51 is extended radially outwards by a lip flexible annular 53, as can be seen more particularly in FIGS. 5 and 6.
- This flexible lip 53 forms, by connecting with the central part 51, a narrow annular groove 54 into which the inner skirt 20 is inserted at its end upper, until taking support by its free edge in the bottom of said groove.
- the throat 54 has substantially the same profile as the upper end of the inner skirt 20.
- the height of the flexible lip 53 is greater than that of the openings 22 and the flexible lip 53 has on its radially inner face, close to its end free, an annular rib 56 capable of being applied sealingly against the surface radially exterior of the interior skirt 20, as illustrated in FIG. 1.
- the flexible lip 53 also has, above the rib 56, a wall thinned 58 intended to facilitate its deformation radially outwards, to allow to the product to gain the pumping chamber 34, as will be explained below.
- the membrane 50 comprises, at the opening of its central part 51, non-symmetrical reliefs of revolution around the axis X, namely bosses 55 of which the function will be specified later.
- these bosses 55 are three in number, being evenly distributed angularly around the X axis, as can be seen in Figure 6.
- Each of these bosses 55 protrudes from the radially inner surface of the central part 51 along approximately a quarter of the height thereof from its upper end, and extends radially outward on the upper face of the membrane 50 to substantially above the groove 54, as can be seen in the figure 5.
- Each of the bosses 55 further presents, when observed in section in a transverse section plane, a convex section towards the X axis, as shown in the figure 6.
- the central conduit 32 of the push button 5 is inserted in the central part 51 of the membrane 50 until it bears, by its lower end, against the bottom 52 of the membrane 50, as illustrated in FIG. 1.
- bosses 55 then apply, in the example described, against the surface cylindrical of revolution of the central duct 32. However, it is not necessary to in general, that the bosses 55 apply to the central duct 32 when the push button is at rest.
- the double sealing lip 24 is applied sealingly to the surface radially inner of the tubular skirt 33, whatever the upward movement or down from push button 5.
- the radially inner surface of the central part 51 of the membrane is slightly conical, converging downwards, for its part extending under the bosses 55 slightly above the upper end of the openings 36, then cylindrical of X axis revolution.
- the support 4, the push button 5 and the membrane 50 constitute a pump the operation of which is as follows.
- the central duct 32 drives down the bottom 52 of the membrane 50, which deforms elastically by stretching to accompany the movement of the duct central 32.
- the pump is here assumed to be primed, i.e. the pumping chamber 34 is filled with product.
- the flexible lip 53 is applied in a sealed manner on the inner skirt 20 during the downward movement of the push button 5.
- the sealing lip 37 of the tubular skirt 33 of the push button 5 ceases, when it reaches the annular withdrawal 41 after a certain driving stroke of the push button 5, to apply in a sealed manner on the guide skirt 16, allowing communication between the inside of the container and the outside, via the air intake orifice 42 and the clearance existing between the guide skirt 16 and the tubular skirt 33.
- the bosses 55 form passages between them for the product and prevent the formation of a sealed annular zone between the central duct 32 and the central part 51 of the membrane 50 which could not be overcome by the pressure of the product, so that the product can flow to the radial openings 36, the membrane 50 being able to move away slightly from the central duct in the vicinity of the upper end of the openings 36 under the effect of product pressure.
- the bosses 55 also tend to keep the central duct 32 coaxial with the inner skirt 20 and to guarantee that the upper part of the membrane hung on the inner skirt 20.
- the narrowness of the groove 54 ensures good adhesion of the membrane 50 on the inner skirt 20 and prevents the membrane 50 from being entrained, at its part upper, moving with the central duct 32.
- the central part 51 of the membrane 50 isolates the radial openings 36 of the pumping chamber 34, and the depression which is created in the latter causes the separation of the flexible lip 53 and an arrival of product from the container.
- the product then wins the pumping chamber 34 circulates by the grooves 25 of the inner skirt 20, along the central part 51 of the membrane 50, crosses the inner skirt 20 through the openings 22, then goes around the lip flexible 53 and rises outside of the latter as illustrated in FIG. 8.
- This spring is housed inside the inner skirt 20, works in compression, and is supported at its lower end on the recess 26 and at its upper end on the underside of the bottom 52 of the membrane.
- This valve can be produced for example by means of a ball 91 shown in broken line in Figure 8, the tip 12 serving as a seat.
- Reliefs 92 are produced on the inner surface of the inner skirt to retain the ball 91 near its seat.
- the ball 91 is chosen to be very rough so as to create a leak making it possible to do not block the downward movement of the central part of the membrane when distribution of a dose of product.
- the ball 91 makes it possible to prime the pump by actuating a small number of times the push button.
- the membrane can also be made of at least two different materials. Thus, a softer material can be used to make the flexible lip 53 than that used to produce the spring portion 51.
- a helical spring is arranged around the central duct and bears at its lower end on the upper end of the membrane and at its upper end on the push button 5.
