Definitions

  • the present invention relates to a pump intended to equip a container, in particular a container containing a cosmetic product.
  • Such pumps are known from WO-A-9 705 043 or US-A-4 315 582.
  • the invention aims more particularly to propose a new pump which is inexpensive to manufacture and reliable to operate.
  • the pump according to the invention comprises a base part secured to the container and is characterized by the fact that it comprises a telescopic assembly, movable axially with respect to this basic part, and defining with it a chamber of variable volume pumping, the telescopic assembly comprising at least one sleeve outside and an inner sleeve sliding in contact inside of it, these sleeves each comprising a distribution passage, these distribution passages communicating with each other when the telescopic assembly is in a configuration of distribution, to then define an exit passage allowing the product contained in the pumping chamber to be dispensed, said dispensing passages ceasing to communicate with each other when the telescopic assembly is in a configuration of filling, the base part having a filling opening through which the product contained in the container can be withdrawn in order to fill the pumping chamber, the telescopic assembly being arranged so that on the one hand, when the sleeve outside is moved to decrease the volume of the pumping chamber, the whole telescopic takes its distribution configuration
  • said means for closing the filling orifice consist of the radially innermost sleeve. Alternatively, they could have a valve.
  • the telescopic assembly comprises only two sleeves only, so the pump is relatively simple to manufacture.
  • the inner sleeve includes a intake passage opening on the one hand at one end by a radial orifice arranged in sight of the filling opening when the inner sleeve is in a position of filling and opening on the other hand at another end by an axial orifice, the outer sleeve being able to close the axial orifice when the outer sleeve is moved so as to reduce the volume of the pumping chamber.
  • the outer sleeve has a top wall capable of closing the above-mentioned axial orifice.
  • the inner sleeve is movable between the top wall of the outer sleeve and a stop provided in the lower part of the outer sleeve.
  • the friction between the sleeve interior and the base part is greater than the friction between the outer sleeve and the inner sleeve.
  • the telescopic assembly comprises three sleeves.
  • the radially innermost sleeve advantageously comprises on its internal surface a part suitable for closing the orifice filling when this sleeve is in a closed position and a proper recess to allow the circulation of product from the orifice of filling when this sleeve is in a filling position.
  • the intermediate sleeve between the radially innermost sleeve and the outer sleeve is movable between a dispensing position in which it bears against a top wall of the outer sleeve and a filling position in which it bears against a stop provided in the lower part of the outer sleeve.
  • the friction between the sleeve outside and the intermediate sleeve is less than the friction between the sleeve intermediate and the radially innermost sleeve, and the friction of the sleeve radially innermost on the base part is greater than the friction of the sleeves of the telescopic assembly between them.
  • the base part includes a chimney provided with minus a lateral opening defining the filling orifice.
  • the invention also relates to a container equipped with a pump such as supra.
  • the pump 10 shown in Figures 1 to 4 is intended to be mounted on the neck 11, of axis X, of a container 12 and comprises a base part 13 provided in part bottom of a mounting skirt 14 shaped to snap onto a bead annular 15 of the neck 11, of a sealing skirt 16 shaped to adjust so watertight in the neck 11, and an end piece 23 for mounting a dip tube 24.
  • the base part 13 comprises in the upper part a chimney 18, comprising a lateral wall 19, cylindrical with axis X, closed at its upper end by a top wall 20.
  • the side wall 19 is crossed, in its upper part, by an orifice filling 21 through which the product from the container can flow, like this will be specified below.
  • the pump 10 also comprises a telescopic assembly 30, composed an outer sleeve 31 and an inner sleeve 32, which can slide one by relative to the other, the inner sleeve 32 being able to slide further on the side wall 19 from the chimney 18.
  • the outer sleeve 31 serves as a push button and has a wall tubular 35 of axis X, closed at its upper end by a top wall 36, perpendicular to the X axis.
  • a stop 37 projecting radially inward is provided at the neighborhood of the lower end of the tubular wall 35, to cause displacement upward the inner sleeve 32.
  • a radial hole 38 forming a distribution passage, crosses the tubular wall 35 in the vicinity of the top wall 36.
  • the inner sleeve 32 is open at its two axial ends and is movable inside the outer sleeve 31 between a position in which it comes support by its lower end 41 against the abovementioned abutment 37 and a position in which it bears by its upper edge 42 against the lower face 43 of the top wall 36.
  • the inner sleeve 32 has an inner passage 45, produced in its thickness, opening at one end through an axial orifice 46 on its upper edge 42, and at the other end by a radial orifice 47 on its radially inner surface 48.
  • the inner sleeve 32 also has a radial hole 53, forming distribution passage.
  • This hole 53 can come opposite the hole 38 of the outer sleeve 31 when the inner sleeve 32 bears by its upper end 42 against the face inside 43 of the top wall 36 of the outer sleeve 31, as shown in the figure 2.
  • a helical spring 50 working in compression, is arranged inside of the inner sleeve 32, bears at its lower end on the top wall 20 of the chimney 18 and at its upper end on the lower face 43 of the wall of top 36 of the outer sleeve 31.
  • the spring 50 could be disposed between the outer sleeve 31 and the base part 13, around the chimney 18.
  • the friction between the inner sleeve 32 and the chimney 18 is greater than that existing between the inner sleeve 32 and the outer sleeve 31.
  • the telescopic assembly 30 defines with the chimney 18 a pumping 60 of variable volume.
  • this pumping chamber 60 is delimited above by the top wall 36, below by the top wall 20, and laterally by the inner sleeve 32 and the part of the outer sleeve 31 located above the sleeve interior 32.
  • the operation of the pump 10 is as follows.
  • the user presses on the top wall 36 of the outer sleeve 31 for moving the latter down, as illustrated in FIG. 2.
  • the inner sleeve 32 remains stationary at first, because the friction forces between the inner sleeve 32 and the chimney 18 are greater to those existing between the outer sleeve 31 and the inner sleeve 32.
  • the axial orifice 46 is then closed by the top wall 36 while the holes 38 and 53 are substantially in alignment with each other and form a outlet passage, allowing the product contained in the pumping chamber 60 to be distributed, as illustrated in figure 3.
  • the inner sleeve 32 is then driven in downward movement together with the outer sleeve 31, against the return action of the spring 50, to distribute the product contained in the pumping chamber 60.
  • the axial orifice 46 is cleared and an air intake can take place as long as the holes 53 and 38 communicate.
  • the product from the container circulates through the interior passage 45 as long as the radial orifice 47 of the inner sleeve 32 communicates with the filling orifice 21.
  • the height of the filling orifice 21 is chosen so that the orifice filling 21 and the radial orifice 47 communicate when the outer sleeve 31 is fully depressed and during its ascent, until it is about to reach its high position.
  • a stop limits the stroke moving up the inner sleeve 32 relative to the chimney 18.
  • the inner 32 and outer 31 sleeves are held in positions predetermined angles around the X axis by means of indexing in rotation, not represented for the sake of clarity of the drawing.
  • FIGS. 5 to 12 show a pump 110 comprising a part base 113, which includes a chimney 119 of axis X.
  • the chimney 119 has a side wall 161 crossed by an orifice filling 156 and a top wall 162.
  • the pump 110 also includes a telescopic assembly 130, which includes an outer sleeve 131, an intermediate sleeve 132 and a sleeve interior 133.
  • the outer sleeve 131 is closed at its upper end by a wall from above 136 and comprises in the vicinity of its lower end a stop 137, directed radially inward.
  • the intermediate sleeve 132 is open at its two axial ends and it is axially movable inside the outer sleeve 131 between a position in which it bears by its upper end 138 against the lower face 139 of the top wall 136 and a position in which it comes to bear at its end lower 140 on stop 137.
  • the outer sleeve 131 has a hole 141, forming a passage for distribution
  • the intermediate sleeve 132 has a hole 142, forming a passage for distribution, which can be positioned opposite hole 141 when the sleeve intermediate 132 bears against the top wall 136, as illustrated in the figure 2, in order to form an outlet passage through which the product contained in the pumping 160 is distributed.
  • the intermediate sleeve 132 has, near its end lower, a stop 150 directed inwards, against which can come to bear the lower end 151 of the inner sleeve 133.
  • the inner sleeve 133 is open at its two axial ends and has a lower part 155 suitable for closing the filling orifice 156 of the chimney 119 and an upper part having a recess 158.
  • the upper end of the inner sleeve 133 has openings 180 whose function will be specified later.
  • a return spring 170 is arranged inside the pumping chamber 160, bearing at its upper end against the top wall 136 and at its lower end against the top wall 162 of the chimney 119.
  • the friction of the inner sleeve 133 on the chimney 119 is greater than the friction of the intermediate sleeve 132 on the inner sleeve 133, which is itself greater than the friction of the outer sleeve 131 on the intermediate sleeve 132.
  • the operation of the pump 110 is as follows.
  • the lower part 155 of the inner sleeve 133 closes the orifice of filling 156.
  • the outer sleeve 131 When the user presses on the outer sleeve 131, the latter begins by moving relative to the intermediate sleeve 132 and the holes 141 and 142 communicate, as shown in FIG. 6.
  • the inner 133 and intermediate 132 sleeves remained stationary.
  • the intermediate sleeve is then supported by its upper end 138 on the top wall 136.
  • the inner sleeve 133 bears on the top wall 136, as illustrated in figure 8.
  • the openings 180 make it possible to prevent the inner sleeve 133 from hampering the product distribution through holes 141 and 142.
  • Air can be taken in through holes 141, 142, the recess 158 and the filling orifice 156.
  • the inner sleeve 133 is then driven in movement towards the high, its lower part 155 closing the filling orifice 156.
  • the return spring may not be mounted in the pumping but between the outer sleeve and the base part.
