Definitions

  • the invention relates to a manually controlled metering pump. for bottle with deformable cover.
  • the beads tend to leave their conical seat and the pump no longer provides a satisfactory sealing of the bottle.
  • a metering pump intended for very viscous fluids, comprising a metering chamber between a valve lower and an upper valve, a pusher pushed back by a spring and a spout communicating with the metering chamber through the central channel.
  • the object of the present invention is to propose a pump ensuring the tightness of the bottle whatever its position.
  • the subject of the invention is a controlled dosing pump manual for bottle with deformable cover, comprising a metering chamber between a lower valve and a upper valve, a pusher pushed back by a spring and a spout communicating with the dosing chamber by through a central channel, the upper valve being carried by a disc constituting the base of a rod hollow integral with the pusher, and bearing under a piston hollow likely to be driven by the pusher, and sliding in the dosing chamber, characterized in that the lower valve is flexible, frustoconical in shape and is held on the bottom of the pump by a key, in that the hollow piston carries a narrowing on which comes lean on a central tube carried by the pusher and in this as the hollow stem widens above the narrowing, an O-ring being disposed between enlargement of the hollow stem and narrowing.
  • the bottle fitted with the pump according to the invention comprises a rigid outer casing 1 and a deformable inner envelope 2 placed inside of the rigid envelope 1.
  • the neck 3 of the deformable envelope 2 is placed on the neck 4 of the rigid envelope 1.
  • a pump doser 5 is placed on envelopes 1 and 2 of the bottle with interposition of a neck seal 6.
  • a cover 7 protection is installed on the pump 5.
  • the pump 5 comprises a body 8 having a skirt external cylindrical 9 capable of snap-fastening by the outside on the rigid envelope 1 of the bottle, a skirt intermediate 10 applying inside the envelope deformable inner 2 of the bottle, and an inner skirt 11. These three coaxial skirts are worn by a ring plate 12 which rests on the neck seal 6 by compressing it to seal between the inside of the envelope deformable 2 and the outside of the bottle.
  • a bottom 13 of the pump 5 Under the flat ring 12 is disposed a bottom 13 of the pump 5.
  • This bottom 13 has an outer cylindrical wall 14 applying to the interior of the intermediate skirt 10 and an inner cylindrical wall 15 applying to inside the inner skirt 11 of the body 8 of the pump 5.
  • These two walls 14 and 15 are connected by a part frusto-conical 16 open downwards, the edge of which exterior protrudes slightly from the wall outer 14 to cooperate with a groove presented by the intermediate skirt 10 in order to ensure the locking in position of the bottom 13 on the body 8.
  • the frustoconical part 16 extends inwards by another part frustoconical 17 open upwards and having a central orifice 18.
  • the frustoconical part 17 of the bottom 13 also has at least one orifice 19 intended to communicate the interior of the deformable envelope 2 with the metering chamber 20 placed above the bottom 13.
  • a flexible, frustoconical lower valve 21 On the frustoconical part 17 open upwards, is disposed a flexible, frustoconical lower valve 21, and held in abutment on the bottom 13 by a through key 22 the valve 21 and the central orifice 18 of the bottom 13.
  • This valve 21 closes the orifice 19 for communication between the inner envelope 2 of the bottle and the dosing chamber 20 of the pump.
  • the body 8 of the pump 5 presents from outside to inside, three walls coaxial: an outer wall 23 extending in the extension of the outer skirt 9, then after a constricted 24, extending by a cylindrical part 25 provided with an outward annular rib for cooperate with the cover 7 while ensuring its maintenance; a intermediate wall 26, attached at least partially to the outer wall 23 at its upper part by arms 27 radials; and an inner wall 28 of substantially same height as the intermediate wall 26.
  • the inner wall 28 carries a flat ring 29 which extends towards the axis 30 of the bottle, and is extends by a cylindrical wall 31 extending towards the high.
  • This cylindrical wall 31 serves as a guide for the piston 32 of the pump 5.
  • This piston 32 is cylindrical and hollow. He introduces about halfway up, a narrowing 33 intended to serve of support for pusher 34 of pump 5. It bears at its base an annular enlargement 35 capable of coming to bear under the flat ring 29. Under this widening 35 is disposed an annular groove 36 in which is disposed an O-ring 37 sealing against the wall interior 28.
  • the pusher 34 essentially consists of a spout 38 at its upper part, a central tube 39 and a bell 40, coaxial with the central tube 39.
  • This bell 40 has a cylindrical skirt 41 capable of sliding inside of the intermediate wall 26.
  • the bell 40 is stressed upwards by a spiral spring 42, which extends from the upper part of the bell 40, inside the skirt 41 of the bell 40, outside the wall interior 28, up to the flat ring 12 on which it takes support.
  • the central tube 39 is capable of sliding at inside the piston 32 until it comes into contact with the narrowing 33. It carries inside a rod 43, hollow, which is integral with the central tube 39.
  • the rod 43 slides inside the narrowing 33 of the piston 32. It widens below the narrowing 33 and between its widening 45 and the narrowing 33 is arranged a O-ring seal 44. Below her enlargement 45, the hollow rod 43 has openings side 46, capable of communicating the interior of rod 43 with the outside.
  • the rod 43 carries a disc 47 on which is disposed an upper valve 48 of shape annular, which rests under the enlargement 35 of the piston 32.
  • the bell 40 wears, outside, a ring 49. Between this ring 49 and the upper part of the intermediate wall 26 is provided with a tearable cylindrical collar, not shown, intended to guarantee that the pump will not be used until it has not been removed.
  • the pusher 34 is in position high, the upper valve 48 is closed, the central tube 39 is not supported on the narrowing 33 of the piston 32 but slightly above, the enlargement 35 of the piston 32 is in support under the flat ring 29, and the lower valve 21 is closed.
  • the metering chamber 20 is defined by the space between the upper valve 48 and the valve lower 21 inside the cylindrical wall interior 28.
  • the pump 5 is shown at the end of pumping stroke.
  • the disc 47 is in the low position at level of the flat ring 12, the upper valve 48 is open, the openings 46 of the hollow rod 43 are free, and the product contained in the metering chamber 20 of the Figure 1 has been routed to spout 38 through the central channel 50 of the rod 43 and of the tube 39.
  • a support manual on pusher 34 lowers the central tube 39 until it rests on the narrowing 33 of the piston 32.
  • the upper valve 48 opens and the product contained in the chamber 20 begins to pass, at through the openings 46 of the rod 43, towards the channel central 50.
  • the downward movement of pusher 34 continues driving the piston 32 which slides in the cylindrical wall 31.
  • the cylindrical skirt 41 of the bell 40 slides inside the intermediate wall 26 and the spring 42 is compressed.
  • the product contained in the chamber 20 flows through the openings 46, the central channel 50 and spout 38.
  • FIG. 1 Another modification concerns the groove 36 for holding the O-ring 37.
  • this groove 36 surrounds the O-ring on three sides.
  • the groove 36 no longer maintains the O-ring 37 only on two sides: the top and the interior.
  • the underside of the O-ring 37 is maintained by the outer edge of the disc 47 constituting the base of the rod 43.
  • the pump according to the invention has been described in the case of a bottle with a deformable wall. Its operation is identical in the case of a piston bottle rising in a cylindrical envelope to keep the product away from air.
