Definitions

  • the present invention relates to a dispensing bottle of a product stored away from air in a flexible bag.
  • Known bottles of this type called “airless”, generally include an attached pump secured to the bag (WO-A-91/18798).
  • the pump of these bottles is a relatively complex and expensive component, typically comprising more than ten parts.
  • the object of the invention is to make it possible to eliminate the need for such a pump for "airless" bottles.
  • the bottle shown in Figure 1, of general axis X-X assumed to be vertical, consists of eight parts: a rigid body 1 itself composed of a lower or upstream body 2 and an upper or downstream body 3; a flexible pocket 4; a lip ring 5 forming a non-return supply valve; a lower cap 6; an upper cap 7; a flexible end piece 8 with lip forming an outlet non-return valve; and a helical spring 9.
  • the lower body 2 consists of a bowl, the bottom of which is provided with a vent 10. Its upper edge 11, provided with an internal bead, forms a support surface for the pocket 4.
  • the upper body 3 of generally tubular shape, has a lower part which slidably fits onto the body 2, and, at a certain distance above the edge 11, a converging part which ends in a vertical cylindrical collar 12
  • the part of the body 3 located above the edge 11 has internally radial ribs 13 which serve to hold the bag and stiffen the bottle.
  • the pocket 4 ( Figures 1 and 2) has a bellows lower part 14, which ends upwards with a circular bead 15 whose outside diameter is substantially the same as that of the lower body 2.
  • the part 14 is extended in a converging part 16, of conical shape, then in a cylindrical part 17, then in a secondary bellows 18 whose outside diameter is slightly less than the inside diameter delimited by the ribs 13, then in an end neck 19 on which protrudes a helical bead 20 forming a thread.
  • the ring 5 ( Figures 1 and 3) has a generally annular shape. It has externally a recess 21 of the same height as the cylindrical part 17 of the pocket, and it is extended upwards by a flexible convergent lip 22. This lip can be continuous if the ring is made of elastomer, or split into several sectors, as shown in Figure 3, if it is made of flexible plastic.
  • the lower cap 6 comprises a cylindrical skirt 23 which internally has a hollow screw thread complementary to the screw thread 20.
  • This skirt has at its upper end a horizontal external flange 24 which ends in a flange 25 directed downwards, as well as '' an annular horizontal inner collar 26 from which a downward cylindrical appendage 27.
  • the latter has a solid lower part 28, a hollow upper part and, just above the part 28, a ring of orifices 29.
  • the upper cap 7 has the general form of a hemisphere open downwards, provided along the axis X-X with a tubular appendage 30 open only downwards.
  • the interior of this appendage communicates with a horizontal outlet duct 31 having a stepped bore.
  • a rod 32 on which a number of radial positioning ribs 33 protrude is force-fitted into the outer part, of larger diameter, of the bore of the conduit 31, and this rod protrudes outwards (FIGS. 1, 4 and 5).
  • the cap 7 is fitted onto the lower cap 6 by covering the flange 25, its appendage 30 penetrating by force into the appendage 27 without reaching the orifices 29.
  • the tip 8 has a generally frustoconical shape. Its large base fits into a groove 34 provided at the end of the conduit 31, while its small base forms a flexible lip 35 which cooperates with the end of the rod 32. As previously, this lip can be continuous or split depending on the material constituting the tip 8.
  • the pocket 4 is placed, by its bead 15, on the edge 11 of the lower body 2, and its part 17 is snapped into the recess 21 of the ring 5.
  • the upper body 3 is fitted on the lower body 2, until to abut on a rim 36 which externally borders the bottom of this body 2.
  • the lower, inclined edge of the ribs 13 then cooperates with the roughly conjugated part 16 pocket to hold the bead 15 on the edge 11.
  • the pocket 4 is almost completely filled, without the introduction of air, of the product to be dispensed, the spring 9 is positioned around the collar 12 of the body 3, then the cap 6-7 is screwed onto the screw thread 20, compressing this makes the spring 9.
  • the lower part 28 of the appendage 27 penetrates, with a slight play, through the lip 22.
  • the orifices 29 are clearly above this lip, and of the product has passed through these orifices to penetrate into the appendix 30 and possibly into the duct 31.
  • the operation of the bottle is as follows.
  • the cap 6-7 At rest, the cap 6-7 is in its high position shown, under the effect of the spring 9. It is assumed that the whole of the pocket 4, including the chamber 37, the chamber 38, the conduit 31 and the 'tip 8 are filled with the product to be dispensed, which is obtained after one or two pressures exerted on the cap.
  • the cap 7 To deliver a dose of product, the cap 7 is pressed in while compressing the spring 9.
  • the resulting increase in pressure in the chambers 37 and 38 has the effect, on the one hand, of closing the valve formed by the lip 22, by applying that -this on part 28 of Appendix 27, and on the other hand to reduce the volume of chamber 37.
  • Product is therefore expelled from this chamber 37 in chamber 38 via the orifices 29. This displacement of product causes the opening of the valve formed by the lip 35, and therefore the output of a dose of product.
  • the lower cap 6 comprises only the parts 26 and 27.
  • the edge of the collar 26 is crimped by means of a ring 39 on the neck of the pocket 4.
  • the lower part 28 of the appendix 27 is tubular, and a collar 40, the upper surface of which defines a conical seat 41, separates this part 28 from the upper part of the appendage 27.
  • a plane valve 42 is pressed against the underside of the collar 40 by a spring 43 , which rests on a perforated cup 44 fixed in the lower end of appendix 27.
  • the upper cap 7 has, near the end of its appendage 30, a circular bead 45, and the spring 9 is secured to this part 7, by snap-fastening of its upper turn in notches provided in radial ribs 46 of this part.
  • FIGS. 7 to 9 use is made of a filling device illustrated in FIGS. 7 to 9 and comprising a rod 47 whose current diameter is slightly less than the internal diameter of the appendage 27 above the flange 40.
  • This rod has a hemispherical end 48 extended by a hollow cylindrical stud 49 open laterally by means of four cross notches 50 formed in its end edge.
  • the interior of the cane 47 can be placed in communication, via two respective conduits 51, 52 provided with valves, either with a vacuum source 53, or with a source 54 of product to be stored in the bottle.
  • the rod 47 is introduced into the appendage 27, until its end 48 is sealed against the seat 41.
  • the stud 49 takes off the valve 42 from the collar 40, crossing it this. This position is shown in the right half of Figure 8.
  • the rod 47 is then connected to the vacuum source 53, which causes the lower part 14 of the bag to be crushed upwards. Then the rod is placed in communication with the source of product 54, so that the part 14 of the pocket, then the chamber 37 through the lip 22, fill with the product.
  • valve 42 is again applied against the collar 40, and inserts the appendix 30 of the upper cap 7 into the appendage 27 until its bead 45 engages in an internal groove 55 of the latter provided between the flange 40 and the orifices 29.
  • the bottle is then ready for use and operates as described above with reference to Figures 1 to 5.
