Definitions

  • the present invention relates to the industry of small manual pumps commonly used for the distribution or spraying of liquid or semi-liquid substances, in particular household, maintenance or cosmetic products, or even pharmaceutical products.
  • patent FR-A-2 318 685 describes a manually controlled pump operating in the normal position or in the inverted position, in which the switching of the liquid admissions to the pump in one or other of the positions is ensured by two opposing ball valves.
  • the invention aims to overcome the aforementioned drawbacks of conventional devices and to make it possible to produce pumps operating in practically any position.
  • the base of the pump body can be extended axially towards the inside of the pump body by a fixed annular piston, sliding inside a movable cylinder secured to the pusher.
  • the cylinder can slide freely over a limited stroke inside a cylindrical extension from the base.
  • the base can be produced simply in the form of an annular plate in leaktight support against the edge of the neck of the container.
  • the base may have an axial tubular housing in which is inserted the base of a flexible, blind tubular piston, the bottom of which is cut to form a tongue in elastic support on an annular shoulder of the bottom of the housing with which it constitutes the first valve. non-gravimetric non-return.
  • the piston has an elastic annular skirt projecting from its side wall, which cooperates with an annular bead of the base to form a third non-gravimetric non-return valve, ventilating the interior of the container by a lateral passage between the piston and the base, opening inside the container.
  • the gravimetric valve for prohibiting admission in the inverted position consists of a ball held in a ball cage, half of which is formed by the end of a tubular end piece, inserted in the tubular stud. fixing the dip tube, having a shoulder for resting the ball with a bypass passage, and the other half of which is constituted by the base of the open frustoconical hat opening axially below the first valve.
  • the non-return valve consists of a biconical elastic washer in the form of an inverted glove finger, the internal inverted conical part of which bears elastically against a cylindrical axial rod coming from the bottom of the cylinder, to form a non-gravimetric discharge valve between the interior of the pump body and a lateral passage to the rod communicating with the dispensing nozzle.
  • the pump shown in these figures essentially comprises a pump body 1, secured by means of an annular seal 11 on the neck 13 of a container 14.
  • the body is held on the neck of the container by a malleable metal capsule 35 which is crimped below the flask of the neck of the bottle.
  • a malleable metal capsule 35 which is crimped below the flask of the neck of the bottle.
  • it could as well be screwed onto a screw neck.
  • This pump body 1 comprises a base 12, extended axially towards the inside of the container by a tubular stud 16, into which is inserted a tubular end piece 8 at one end of which is inserted a dip tube 3, opening at the bottom of the container 14 which contains substance 15 to distribute.
  • the other end of the tubular end piece 8 constitutes the lower part of a ball cage and has an annular shoulder 28 on which a ball 26 can come to rest, while a radial slot 29 constitutes a diversion passage around the ball 26 to allow substance 15 to bypass the ball.
  • the upper part of the ball cage is constituted by a frustoconical cap 30, of elastic material, the end of the outer wall of which abuts against an annular shoulder 31 of the stud 16, to form a non-gravimetric non-return valve. substance 15, bypassing the dip tube 3 by a radial lumen 10 bypass pierced in the stud 16 of the base 12, when the container is inverted.
  • the base 12 is extended axially opposite the stud 16, carrying the plunger tube and the ball cage, by an axial tubular housing 19 in which is inserted the base of the flexible and blind tubular piston 4 whose bottom is cut to form a tongue 21, which comes into resilient abutment on an annular shoulder 22 of the bottom of the housing 19 with which it constitutes a non-gravimetric non-return valve, which allows the entry of the substance to be dispensed from the dip tube in the normal position, and in coming from the bypass channel 10 in the inverted position, under control of the lip of the frustoconical cap 30, which curves elastically from its seat formed by the shoulder 31 under the effect of the suction.
  • the piston 4 also has an annular skirt 23, projecting from its side wall, which bears elastically on an annular bead 24 of the base 12 to form a non-gravimetric non-return valve, which allows ventilation of the interior of the container when a depression is manifested therein, by entry of outside air into a passage formed by a radial groove 25 hollowed out in the base 12 which opens, on the one hand into the space between the skirt 23 of the piston and the bead 24, and d on the other hand in the radial duct 10 of the tubular stud carrying the dip tube.
  • the fixed piston 4 slides inside a movable cylinder 2 secured to a manual pusher 5 inside a cylindrical extension 18 coming from the base 12.
  • the stroke of the cylinder 2 is limited by an annular shoulder 36 of the end of the cylindrical extension 18, against which comes an outer shoulder 37 of the cylinder 2.
  • the base 2 is inserted elastically in the cylindrical extension 18 into which it snaps, and the assembly is strengthened by a chimney 38 extending the capsule 35.
  • the bottom of the cylinder 2 is extended by a tubular end piece 39 which fits tightly inside the pusher 5, in communication with a radial duct 40 opening into a conventional spray nozzle 6, with a vortex effect in the mode shown.
  • the nozzle can be replaced by a simple nozzle.
  • the tubular end piece 39 communicates with the interior of the cylinder 2 by an offset axis 34, parallel to an axial rod 33 projecting inside the cylinder 2.
  • the internal inverted conical part 32 of the washer 7 bears elastically around the rod 33, thus forming a non-gravimetric delivery valve which authorizes the passage of the substance during the delivery to the nozzle 6 through the passage 34, the nozzle 39 and channel 40, but prohibits any entry of air during aspiration.
  • the pump according to the invention can operate efficiently in practically any position, provided that the end of the dip tube 3, or the radial passage 10, is immersed in the substance to be dispensed.
  • the invention makes it possible to obtain maximum operating efficiency over practically 360 °, in contrast to the other known systems, in particular thanks to the arrangement of the driving members above the neck of the container, and to the housing of the reversing members in the immediate vicinity. of the driving members, in the container booklet, which minimizes, in a horizontal position, the annular volume of product to be distributed between the interior of the container neck and the tubular stud of the pump.
