Definitions

  • the present invention relates to a toilet atomizer made of molded non-rigid unbreakable plastic material, comprising two main parts, namely: the atomizer unit and the independent screw-cap adapted to be screwed on the threaded neck of a bottle.
  • the atomizer unit in principle, is made of one piece or head rigid with a pump cylinder in which a piston is mounted for reciprocating movement in order, in one direction, to expell the atomizring air and which is moved in the opposite direction by a restoring spring.
  • This piston is retained within the cylinder by a molded annular ridge.
  • the air blown out by the piston enters a bent canal provided in the head.
  • An atomizing unit positioned at the outer end of this canal ensures sucking therliquid out of the bottle and atomizing it.
  • the screw-cap is preferably entrapped within the head while remaining independent therefrom.
  • the sealing property of the apparatus is obtained by virtue of a reserve chamber provided within the head and communicating, on one hand, with the outside, and, on the other hand, with the bottom of the screw-cap.
  • Fig. l illustrates the atomizer in longitudinal section
  • Fig. 2 is a fragmentary, somewhat sketchy, transverse section of the atomizer head, taken along the axis of the atomizing unit, and
  • Fig. 3 is a sectional detailed View of the piston.
  • the atomizer comprises a head 1 (Figs. l and 2) rigid with a pump cylinder 2.
  • a reciprocating piston 3 with an axial bore 4 formed with splines 5 adapted to slide on a stem 6 moulded solid with the cylinder 2 for guiding said piston.
  • the piston 3 is formed with an axial boss extending inwardly so as to form an abutment 7 on which is mounted the compression seal S'provided with a central bored hub 8 which ensures a correct positioning of said seal.
  • a helical spring 11 restores the piston 3 after'its active stroke back to its original position shown in the drawing.
  • the piston at the end of its compression stroke bears against the reinforcing portion 12 provided in the bottom of the cylinder 2 and, at the end of its return stroke, its rear peripheral edge bears against the annular moulded ridge 13 of the cylinder.
  • a passage 14 leads the air to the atomizer unit 15 (Fig. 2) which is forcedly engaged with its rear and foremost into a bore 16 which is an extension of the passage 14 at right angles thereto, the head of the atomizing unit being positioned in the bore 17.
  • the atomizer unit 15 has a throat 18, a lsucking duct 19, an atomizing outlet 20 and a diverging cone 21.
  • Engaged in a central nipple 22 is a flexible hose 23 for sucking the liquid which flows up through the duct 23 into the bore 1'7 in which theatomizer unit is accommodated.
  • the flexible hose 23 is pressed against the inner wall of the central nipple by a rigid lring 24 forced into said hose (Figs. l and 2).
  • a screw cap 26 (Figs. l and 2), which is made of a hard material or of a material similar to that of the head, has a central bore through which extends the central nip-ple 22 and through which air may enter the bottle; said cap is housed within the head of the atomizer. It is retained by its lower end abutting against an annular ridge 2S (Figs. l and 2) moulded with the head.
  • a reserve chamber 32 which communicates with the atmosphere through an orifice 33 positioned approximately half-way up the chamber 32.
  • the threaded cap 26 has its upper face bearing against shoulders 34 of the head.
  • the cap has one or more lateral dovetailed ribs 36 housed in corresponding grooves 37 of the head, whereby the screw cap is prevented from rotational movement within the head.
  • a passage 38 for the air constituted for instance by a very small V-shaped notch, which, however may have any other suitable form.
  • the operation is as follows: the user presses his thumb against the middle of the piston 3 whereby the orifice of the bore 4 is obturated, the air contained in the cylinder 2 escapes through the passage 14, then through the bore 16 and out of the atomizing unit 15 where it suddenly accelerates by passing the throat 1S, When passing the sucking duct 19, the air stream createsv an underpression and sucks the liquid contained in the bottle through the sucking duct and hose 23. The liquid is immediately fed into the atomizing outlet 20 whence it is discharged and atomized and then spread out by the diverging cone 21.
  • the atomizer is mounted on Vthe bottle by screwing engagement thereon.
  • the cap 26 is independent from the head 1 of the atomizer, though it is housed within said head, it is possible, once the atomizer is tightly screwed, to further effect the rotating movement in the direction of screwing the head on the bottle.
  • An atomizer unit adapted to be mounted on a container comprising, in combination, a hollow head having an open end adapted to be fluid-tightly connected to said container and a closed end closed by an end Wall of said hollow head; a wall extending transversely through the interior of said hollow head intermediate said open and said closed ends thereof so as to ⁇ form a reserve chamber adjacent said closed end of said head; pump means connected to said head for providing compressed air; atomizing means located in said head and communicating with said pump.
  • first air passage means formed in said head intermediate said end wall and said transverse wallthereof for providing communication between the 'atmosphere and said reserve chamber at a location spaced from said end wall; second air passage means formed in said transverse wall for providing communication between said reserve chamber and said open end of said hollow head, whereby even if the unit is used in inverted position air may iiow through said first and said second air passage means into said container while liquid. may seep from the container through said second air passage means into said reserve chamber to be contained therein without seeping through said first air passage means to the outside of the unit.
