Definitions

  • the present patent application for industrial invention relates to an improved dropping vessel.
  • the present invention has been devised following to a critical observation of the known models of dropping vessels which comprise a nozzle from where the liquid contained in the vessel is dispensed drop by drop.
  • the said dropping vessels are provided with a thin glass tube having a lower end intended to be immersed in the liquid to be dispensed, and an upper end provided with a rubber dropper, the compression of which determines the dispensing of a drop of liquid.
  • FR2598624 discloses an external device for injecting a medication of the like, in particular insulin, in the human body.
  • US4367739 discloses a syringe for precisely dispensing fluids, comprising means for indicating the pressure applied to the fluid being dispensed.
  • US5813572 discloses a dispenser particularly useful for dispensing toothpaste including a tubular body closed at one end and having an opening for receiving the neck portion of a toothpaste tube disposed inside the dispenser.
  • the purpose of the present invention is to remedy the drawbacks of the prior art by disclosing a dropping vessel that can be easily used also by blind or deafblind persons.
  • the dropping vessel of the invention comprises:
  • the dropping vessel of the invention is disclosed, which is generally indicated with reference numeral (100).
  • the dropping vessel (100) comprises:
  • the said spring means (5) comprise a leaf spring.
  • the dropping vessel (100) further comprises:
  • the anti-tampering means comprise a first strap (F1) that is removed upon the first use of the dropping vessel (100), and a second strap (F2) that is removed only when the liquid inside the cylinder (1) is about to finish, informing the user that the liquid is about to finish and it is necessary to buy another dropping vessel (100).
  • the lower cap (9) contains an antiseptic disinfectant seal suitable for guaranteeing the tight closing of the nozzle (12) of the cylinder (1).
  • both the upper closing element (4) and the lower closing element (2) of the dropping vessel (100) of the invention have a cylindrical configuration and comprise an external lateral surface (4a, 2a) provided with protuberances in Braille characters indicating the name of the liquid contained in the chamber (11) of the said cylinder (1).
  • the stem (30) of the piston (3) is movably mounted with respect to the upper closing element (4) with screw-female screw coupling.
  • the stem (30) of the piston (3) comprises an external thread and the upper closing element (4) is provided with an internally threaded hole (40) wherein the said stem (30) is screwed.
  • the dropping vessel (100) of the invention also comprises anti-rotational means (7) suitable for preventing a rotation of the stem (30) of the piston (3) in the chamber (11) of the cylinder (1).
  • the said anti-rotational means (7) comprise a disk joined to the cylinder (1) and provided with a hole (70) wherein the stem (30) of the piston (3) slides without rotating.
  • each movement of the upper closing element (4) with respect to the lower closing element (2) corresponds to a sliding movement (30) of the piston (3) in the chamber (11) of the cylinder (1) along a vertical direction (Y-Y).
  • the piston (3) is provided with an annular groove (32) and the dropping vessel (100) of the invention comprises an elastic ring (8) inserted in the said annular groove (32) of the piston (3) in order to act as seal.
  • the cylinder (1) comprises an upper edge (13) provided with a plurality of notches (14) and the anti-rotational disk has an external edge (71) provided with a series of ribs (72) that engage inside the notches (14) of the upper edge (13) of the cylinder.
  • the dropping vessel (100) of the invention also comprises a closing metal ring (6) intended to be coupled with the lower closing element (2) in such manner to connect the upper closing element (4) with the lower closing element (2).
  • the said closing metal ring (6) comprises a threaded internal annular surface (60) and the lower closing element (2) comprises a flange (2b) from which an externally threaded shank (2c) protrudes upwards, whereon the closing metal ring (6) is screwed.
  • a snap-in or fit-in coupling can be provided between the closing metal ring (6) and the lower closing element (2).
  • the said clicking means (41, 61) comprise a first toothing (41) obtained on a flange (41) of the upper closing element (4) and a second toothing (61) obtained on the closing metal ring (6).
  • the distance between two consecutive teeth of each of the two toothings (41, 61) is adjusted in such manner that every click between the two toothings (41, 61) corresponds to a sliding movement of the piston (3) in the chamber (11) of the cylinder (1) along the direction (Y-Y) and to the dispensing of a drop of liquid from the nozzle (12) of the cylinder (1).
  • a rotation of the upper closing element (4) with respect to the lower closing element (2) determines a click between the two toothings (41, 61) and the sliding of the piston (3) in the chamber (11) of the cylinder (1), consequently dispensing a drop of liquid from the nozzle (12) of the cylinder (1).
  • the leaf spring After dispensing a drop of liquid from the nozzle (12) of the cylinder (1), the leaf spring tends to push the upper closing element (4) upwards, generating a vibration that allows the blind or deafblind user to understand that a drop of liquid was dispensed.
  • the piston (3) is slightly raised upwards, sucking the remaining liquid outside the nozzle (12) and avoiding the stagnation of liquid outside the nozzle (12).
