Definitions

  • the nozzle comprises a generally conical member having an axially extending passageway for the discharge of material, and the nozzle toward its discharge end has diametrically opposed wedgeshaped portions removed therefrom so as to provide a crosssectional width in one direction which is significantly less than that in a cross-sectional plane at right angles to the first, thereby providing a discharge end which may be readily inserted into a lock or the like but which nevertheless has suffrcient strength to resist deformation.
  • the present invention relates to a spray nozzle for aerosols and other spray devices adapted for spraying a liquid, powder or the like, particularly an antifreeze agent and/or a lubricant into and onto a lock, hinge and the like.
  • Nozzles of the aforesaid type are previously known, particularly such for introducing a liquid into a lock.
  • the nozzle comprises a body with a central straight passage.
  • the body converges in the spraying direction and terminates with a relatively blunt point into which the passage opens.
  • the point size is determined by the strength and other properties of the material of which the nozzle is manufactured.
  • the point being intended to be inserted into a hole, it must have relatively good resistance to upsetting and wear, for example as otherwise the passage opening will be damaged and the atomization of the liquid be disturbed. For this reason, the passage opening must be surrounded by a relatively great amount of material. This results in a blunt shape of the point in relation to the keyhole into which the point is to be inserted. As the keyhole in many cases has small dimensions, it can be difficult to introduce the liquid into the lock interior.
  • the invention has as its object to produce a nozzle which with substantially maintained strength has a point of less blunt shape and, therefore, can be inserted more easily into small holes, and which at locks with a covering plate can move aside the latter and be inserted such a distance that the point and its passage opening is located to the inside of the plane of the covering plate, but outside the tumbler located closest to the keyhole.
  • this object is achieved in that the nozzle in two perpendicular axial planes to the passage has in one of said planes toat least part of its length a cross-sectional width which substantially corresponds to that of conventional nozzles, while its width in the other plane is considerable smaller at a corresponding distance from the point in the first plane.
  • the narrower portion may be terminated by a stop surface which is substantially perpendicular to the passage and so dimensioned, that the width of the noz-
  • FIG. 1 shows a nozzle according to the invention seen from above
  • FIGS. 2 and 3 show a section along the lines Il-ll and Ill-Ill respectively in FIG. 1. a
  • the nozzle according to the invention is shown in FIGS. 1- 3 as a substantially conical body 1 having a central straight medium flow passage 2 which in its part facing away from the point comprises a widened portion 3 adapted to be threaded onto a container valve tube 4.
  • the outflow valve to the container (not shown) is opened by moving said tube 4 by the nozzle downwards in FIGS. 2 and 3.
  • the nozzle in the section II-Il to approximately half its length has a width which is substantially smaller than that in the section Ill-III.
  • This narrower portion of the nozzle is terminated in the axial direction by stop surfaces 5 extending substantially perpendicular to the passage 2.
  • the narrower portion is preferably given a length of the order of about 7 mm. which usually is sufficient for the point to reach inside of a covering plate possibly disposed in the keyhole mouth, which length, however, must not be greater than that the point is zle in the said perpendicular planes is substantially equal on the other side of the stop surface, seen from the point.
  • a peripheral flange may be placed which serves as a stop when thenozzle is being inserted into a greater hole, and which also facilitates the gripping when a liquid is to be spread across a surface or the like and where the return movement of the nozzle for opening the container valve cannot be effected in such a manner that the container is pressed against the hole and the entering of the nozzle is stopped by the said stop surfaces.
  • the liquid then is sprayed into the lock, in such a manner, that the container is pressed in the direction to the lock whereby the valve tube 4 is pressed into the container and the valve opens.
  • the nozzle may preferably at its rear part be provided with an additional stop surface substantially perpendicular to the passage 2 and formed as a peripheral flange 6 which at greater holes has exactly the same function as the first stop surface 5.
  • Said flange 6, moreover, offers the advantage of facilitating the gripping around the nozzle when a liquid is to be spread across a surface or the like, in which case the spraying is effected by pressing the nozzle with the hand back to some distance from the object to be sprayed.
  • the embodiment of the nozzle shown on the drawings can be modified in several respects.
  • the basic shape thus, need not be conical, but may also be a pyramid or some other body with a substantially converging shell. It may for special purposes be provided with several steplike stops 5, and/or the narrower portion may be made longer or shorter.
  • the field of application is not restricted to that mentioned above, i.e.
  • the nozzle may be applied in all connections when the medium is desired to be sprayed through a larger or smaller hole in a wall to a space, for example in hinges with lubrication holes or the like, or when a medium layer is to be spread across a larger or smaller open surface.
  • said member being of generally conical shape and having a passageway along its axis for the discharge of said substance and said carrier in a direction toward its narrowed end;
  • said member having diametrically opposed portions removed from its conical outer surface from its discharge end to substantially halfway along its axial length;
  • each said removed portion being defined by a first surface generally normal to the axis of said member and a second surface extending to said discharge end at an acute angle to said axis;
  • said two first surfaces being generally coplanar and together forming a stop ledge to control the depth of entry of said discharge end into the aperture;
  • said nozzle having a straight, central and preferably cylindrical passage for the outflow of the liquid and the gaseous carrier, characterized in that the nozzle includes three portions, a first of said portions including the nozzles tip and having flat side surfaces which form a small angle with the nozzles main axis, a second of said portions being adjacent to said first portion and having a frustoconical shape, whereby a stop surface being perpendicular to said main axis is formed in the transition between said first and second portions, and a third of said portions being adjacent to said second portion and forming a flange, whereby a further surface being perpendicular to said main axis is formed in the transition between said second and third portions.
