Definitions

  • This invention has for its principal object to improve the functioning of flasks with spray-heads, of the type comprising an elastically deformable liquid storage chamber equipped with a valve which is sealingly applicable against a seat under the effect of the pressure developed in said chamber in the course of its compression during the spraying phase and which is lifted from said seat during the reinflation phase of said chamber and uncovers an additional passage venting the space inside said chamber to the surrounding atmosphere, said additional passage being preferably formed in said head, or in a plugging member supporting said seat, or between said head and said member.
  • a spray-head according to the invention is axially movable loosely in a plug mounted on the neck of a flask having a flexible and elastic wall, and said spray-head is provided, internally, with a large fitted washer acting as a valve, externally with a set of restraining protrusions arranged in star-fashion, and, between said washer and said protrusions, with uniformly disposed guide ribs adapted to be slidable in a slideway of said plug, whereby to form air intake passageways between the slideway and the head.
  • protrusions arranged in star-fashion act to limit the inward travel of the plug during reinflation of the flask and contact a serrated bearing surface of the fitted plug, thereby further increasing the air throughput during reinflation.
  • the slideway for the spray-head in the plug is formed internally with a relieving groove, thereby imparting the required resiliency to said slideway by reducing its wall thickness.
  • the spray-head receives internally a driven-in insert the function of which is to act as part of the spraying means and bound the air and liquid passageways.
  • the present invention additionally permits of obtaining a spraying device which is more pleasant to handle.
  • FIG. 1 shows in axial section the spray-head and the associated plug, both mounted on the neck of a flask with a resilient and elastic wall, in the position occupied by said head during spraying;
  • FIG. 2 is a corresponding sectional view showing the spray-head in the position it occupies for air to be admitted into the flask during reinflation;
  • FIG. 3 is a sectional view of the assembly, but in which the spray-head itself is not sectioned and occupies the plugging position;
  • FIG. 4 is a fragmental section taken along line IV- IV of FIG. 3;
  • FIG. 5 is a fragmental section taken along line VV of FIG. 3;
  • FIG. 6 shows in side elevation on a smaller scale, a spray flask of reduced length equipped with a head according to the invention.
  • the device illustrated in the drawing comprises, a neck 1 with screw-thread 2 formed on a flask 3 by blowing or moulding a flexible and relatively elastic synthetic plastic material such as polyethylene.
  • plugging means comprising a nut portion 4 with end flange 5 fiuidtightly screwed onto said screw-thread.
  • the flange 5 has formed thereon an internal reinforcement 6 which includes, behind an outwardly opening slot 6a, a cylindrical slideway 7.
  • the nut 4 is made in one piece from synthetic plastic material which is relatively less flexibie than the material used for the flask.
  • the slideway 7 Toward its end located within the flask, the slideway 7 is provided with a flat-ended protruding rim 8 forming a seat and, on its opposite externally located end, with a serrated endsection 9.
  • slot 6a facilitates moulding operations by rendering homogeneous the thicknesses of material to be heat-treated in the mould, while the relative thinness of the slideway 7 endows it with a degree of elastic resiliency.
  • the hollow cylindrical body 10 of a spray-head Into the slideway 7 is driven the hollow cylindrical body 10 of a spray-head. At the inner extremity thereof, and at the end of a reduced section 11 of a diameter less than that of the interior passage of the slideway 7, said hollow cylindrical body has shrink fitted thereon an annular portion 12 of a flat, fitted valve-seat 13 adapted to be applied against the fiat end-section of the rim 8.
  • the spray-head 10 has a smooth-walled cylindrical section 14 the diameter of which is at least equal to and preferably slightly greater than that of the interior passage of the slideway 7.
  • This cylindrical section 14 is surmounted with a cap 15 forming a grip and having an annular face 15a which is adapted to cover the serrated end-section 9 of said slideway and the opening of the slot 6a when the cylindrical section 14 is driven into the slideway 7 (see FIG. '3).
  • protrusions 17 which project from section 11. These protrusions have a depth in excess of the clearance existing between the section 11 and the internal passage of the slideway 7. Between each protrusion 17 and an adjacent portion of the washer 13 are formed raised straight ribs 18, and the degree to which these ribs are raised is such that they slide easily through the slideway 7.
  • the distance separating the face of the washer 13 bearing against the fiat-end-section of the rim 8 from the protrusions 17 is greater than the height of the slideway 7, so that when said washer 13 is applied against the endsection of the rim 8 (see the spraying position shown in FIG. 1), the protrusions 17 are in spaced relation with the serrated end-section 9. Conversely (flask reinflation position shown in FIG. 2), when the protrusions 17 are in contact with the serrated end-section 9, the washer 13 is in spaced relation with the end-section of the rim 8.
  • a spraying nozzle 19 constituted by an outwardly opening frusto-conical section and a cylindrical section opening into the hollow portion 20 of the head 10.
  • This hollow prismatic portion 20 has a square base and two of its opposite sides have formed therein facing grooves 21 and 22.
  • a relatively rigid plastic part 23 is driven into this prismatic portion.
  • This part 23 is of generally prismatic shape with a square section matched to that of the hollow portion 20.
  • the part 23 has formed therein a cylindrical hole 24 which opens into the groove 21.
  • the part 23 is provided with a groove 28 which opens out opposite the tuyere 25.
  • the tube 31, the groove 29, the passage formed by the grooves 22 and 28, the tuyere 25 and the hole 24 form a passageway for the liquid contained in the flask 3, which is driven thereinto when the wall of the flask 3 is deformed by manual pressure.
  • the passageway formed by the reduced section 27 and the groove 21, on the other hand, provides a passageway for the air which is also contained in the flask and which is expelled at the same time.
  • the air propelled thus meets the jet of liquid issuing from the hole 24 and is expelled with it through the nozzle 19 in the form of a spray, the fineness of which will bedetermined by the relative sections of the different orifices and passages.
  • moulding of the head 10 offers no serious difliculty since there are no large back-oft portions other than on the relatively shallow protrusions 17, and because the sealing washer 13 is fitted after the head 10 has been inserted into the slideway 7.
  • the washer 13 can be stamped out of a metal blank.
  • the air return into the flask 3 is improved by the co- 7 operation between the protrusions 17 and the serrated edge 9 of the slideway 7 and also by the provision of the ribs 18 on the head 10, which n'bs slide easily along the slideway 7 and enable the head 10 to slide without vibration through the slideway 7.
  • the air return is additionally facilitated by the wide gap possible between the washer 13 and the rim 8.
  • the pretically deformable wall and a spray-head which is movable between an extended sparying position by compression of the wall of the flask, and a retracted reinflation position upon subsequent release of the wall, an improvement in which an additional air passage is provided upon movement of the spray-head from the extended position towards the retracted position to insure rapid reinflation of said flask, said improvement comprising a plug mounted on the flask and provided with a groove to define a slideway having a wall of substantially.
  • the spray-head including a first portion having'a smooth outer surface which normally projects from the plug and a second portion of reduced diameter which is freely slideable in said slideway between the extended and retracted positions, ribs on said second portion of the spray-head having clearance in said slideway and forming and a washer on the second portion of said spray-head for contacting the plug in the extended position of the spray-head to blocksaid air intake'passages and be in sealed relation with said plug, said spray-head being forceably insertable into the slideway to cause said protrusions and said first portion to enter the slideway and close and seal the flask.
