Definitions

  • the object of the present invention is a hand sprayer for liquids, as defined in the prior art portion of claim 1, having guarantees against possible tampering, which will show when the sprayer has been previously used and prevent its re-use when the liquid contained in the container onto which the nozzle is applied has been used up.
  • FR-A- 2 081 938 describes a sprayer wherein a cap covers the head of the sprayer.
  • the cap comprises a cylindrical mantle fixed to the head and a tap attached to the mantle by an elastic tongue and closing the nozzle of the sprayer provided in front of the head.
  • One aim of the invention is to provide a sprayer which can be made at low cost, and which will indicate with reliability if the sprayer has been previously used.
  • Another aim of the invention is to provide such a sprayer, provided also with means to prevent it being taken off the container onto which it is applied, or at any rate to show that it has been taken off.
  • an outer jacket or cover is fitted on the body of the sprayer, provided with means suitable for engaging permanently with complementary means borne on the body of the sprayer, in such a way as to prevent its subsequent removal.
  • a door is placed in front of the latter having a conical projection inside, which moves to close the spray nozzle.
  • This door is hinged, for example at the top of the sprayer cover, by means of a line where the material is weakened, and is sealed to the cover by means of one or more connection bridges, to be broken the first time the door is opened and therefore when the sprayer is first used. After use the door can be re-closed, in such a way that its inside projection moves to close the spray nozzle.
  • the permanent engaging means between the outer cover and the body of the sprayer consist of at least one elastic fin with an end tooth, and of a corresponding stop.
  • the body of the sprayer is made integral with the container, even in rotary motion, by the provision of reciprocal engaging means, as for example illustrated in the Italian Patent Application No. 20533 A/89 and the Italian Utility Model Application No.
  • a sprayer for liquids according to the invention is shown as a whole with 1, applied to a container 2, from which the liquid is drawn by the operation of a control lever 3, and sent out by means of a spray nozzle 4, in an already known way.
  • the sprayer 1 has a body 5 rising from a base 6, from the lower part of which a tubular appendix 7 projects, intended to be housed inside the neck 8 of the container 2.
  • the application of the sprayer 1 onto the container 2 is carried out by screwing down a threaded ring 9, foreseen outside the tubular appendix 7, on the neck 8 of the container.
  • a circular peripheral flange 10 is foreseen, determining with the base 6 an annular groove 11, in which the upper edge 12 of the ring 9 is received in a fixed way.
  • a groove 13 is made on the appendix 7 suitable for engaging with a rib 14, provided inside the neck 8 of the container 2, or vice versa.
  • an indentation 13' may be made, suitable for engaging with a complementary indentation 14' foreseen inside the neck 8 of the container 2.
  • the engaging means 13, 14 and 13' and 14' can also be foreseen in combination.
  • means are also foreseen which prevent the ring 9 being unscrewed.
  • Such means consist of at least one and preferably two elastic tongues 15 projecting downwards from the base 6, facing the direction for screwing on the ring 9, and of grooves 16 foreseen on the upper edge of the ring.
  • the ring 9 can only be screwed down onto the neck 8 of the container 2, causing the bending of the elastic tongues 15, while any unscrewing of the ring is prevented by the same tongues 15, which would break in the event of being forced, thus showing that the sprayer had been tampered with.
  • An outer jacket or cover 17 is fitted onto the body 5 of the sprayer, having a door 18 at the front hinged to the cover 17 by means of an upper line 19 of weakened material, and sealed to the cover itself by means of lower connection bridges 20.
  • the cover 17 has two lateral body sides 21, having respective widenings 22 lower down, sliding on a pair of guide tracks 23 foreseen above the base 6 of the sprayer.
  • Mounting the cover 17 onto the body 5 of the sprayer is carried out by lowering it onto the base 6, in such a way that the said widenings 22 of the body sides 21 come into place in correspondence with the openings of the sliding guides 23, and then moving it towards the left with reference to figure 1, in such a way that such widenings slide and remain engaged in the corresponding guides 22.
  • a conical projection 24 foreseen inside the door 18 moves to close the spray nozzle 4, and an end tooth 27 of at least one fin 25, projecting downwards from the upper wall 26 of the cover 17 moves to engage unremovably with a corresponding projection 28, foreseen on the body 5 of the sprayer, to which a second guide projection 29 may possibly be opposed.
  • the sprayer according to the invention offers a complete guarantee against any type of tampering. Drawing off liquid from the container is, in fact, prevented by the guarantee seal, consisting of the connection bridges 20, foreseen on the door 18 of the cover 17, while the possibility of taking the sprayer 1 off the container 2 is prevented by the engaging means 13, 14 and/or 13', 14' between the sprayer and the container, and by the means 15 and 16 which prevent the ring 9 being unscrewed.
