Definitions

  • the present invention relates to a drip tip for a bottle, of the type comprising a plastic body traversed longitudinally by a flow channel.
  • the nozzles of this type intended in particular to equip bottles with ophthalmic products, must be capable of delivering the product drop by drop, without pressure, even if the user develops in the bottle, which is generally made of flexible plastic material, relatively high pressure.
  • the channel is generally produced with a circular section of decreasing diameter towards the inside, that is to say towards the inside of the bottle in service, the inlet diameter of the channel being about 0.2 mm for example.
  • the invention aims to allow the very reliable industrial production at high speed of the drip tips.
  • the subject of the invention is a drip tip of the aforementioned type, characterized in that, over at least part of its length, the channel has, in cross section, the shape of a star with at least three branches.
  • the invention also relates to a liquid bottle, in particular of flexible plastic material, provided with a drip tip as defined above.
  • the nozzle 1 shown in Figures 1 to 6 is intended to equip the neck 2 with a bottle 3 typically made of flexible plastic.
  • the neck 2 is provided with an external thread 4 for the screwing of a cap, not shown, and has at its free end a counterbore 5 internally bordered by a bead 6.
  • the end piece 1 molded in one piece from injected plastic, has a tubular base 7 which ends outwards by an external collar 8 received in the counterbore 5.
  • a circular bead 9 in radial projection located at a small distance under this flange allows the base 7 to be snapped into the neck opening, while a circular bead 10 projecting axially under the flange 8 provides sealing by cooperating with the upper face of the counterbore.
  • the end piece forms an annular body 11 of roughly conical shape converging upwards. From approximately the halfway up this body, protrudes downwards a central protuberance 12 surrounded by an annular space 13.
  • This protuberance has an outwardly substantially frustoconical shape, converging downwards, up to the level of the flange 8, then forms a step horizontal 14 then a lower appendage 15 also frustoconical and converging downwards but of reduced diameter.
  • a flow channel 16 passes through the body 11 from its upper end to the step 14.
  • This channel has in cross section the shape of a regular star with four radial branches 17, that is to say a cross .
  • the median plane of each branch contains the central axis X-X of the endpiece, and its two lateral faces are substantially parallel to each other.
  • the spacing d ( Figure 2) between these two faces is small enough, depending on the liquid to be dispensed, to create a capillary effect.
  • the section of the channel 16 decreases slightly from the top to the bottom, to constitute a draft facilitating demolding.
  • the channel 16 extends over a very small distance h less than d below the step 14, and, at this level, each branch of the channel opens radially on the peripheral surface of the appendage 15 through a window 18.
  • Each window thus has a circumferential dimension greater than its height.
  • d 0.3 mm at the top of channel 16 and 0.2 mm at its lower end
  • h 0.05 mm.
  • the free end of the channel has, over a short length, a circular section.
  • a needle with a cross-shaped cross-section of the channel 16 is used, and a counter-piece which defines the windows 18 by cooperating with the lower end of this needle.
  • the cruciform needle has a high inertia which allows it to very well resist buckling and bending during the injection of the plastic material.
  • Figures 7 to 11 differs from the previous one only in that the channel 16 forms a regular star with three branches 17.
  • Figure 12 differs from that of Figures 7 to 11 only in that the channel 16 has a star shape only over a fraction of its length, for example over a third of its length, from its inner end, that is to say from the windows 18. Beyond, that is to say over the rest of its length, the channel 16 has a considerably enlarged circular section, with a diameter typically of the order of a millimeter.
