Definitions

  • a spray nozzle assembly having a liquid-atomizing mechanism so designed that a plurality of liquid streams are fed while being rotated spiralwise at high speed so as to collide against each other in a cavity provided adjacent the terminals of the passageways of the streams and that, while taking-in the air located therearound, the collided streams of liquid are atomized.
  • This nozzle assembly features that the sealing-off of the liquid from the liquid container, the control of the diverging angle of spray as well as the size of the atomized liquid particles can be effected all in one procedure, namely, by turning the cap member.
  • the present invention relates to a spray nozzle assembly for use in spraying toilet preparations such as hair lotion and perfume, and also chemical solutions including insecticidal solutions, and more particularly, to a spray nozzle assembly which is suited for use with a volatile material such as petroleum products and which permits the closing off of the liquid from the liquid container as well as the adjustment of the size of the atomized liquid particles with a single manual procedure, namely, tuming the cap of the assembly.
  • spray nozzle assemblies may be roughly grouped into the following two types.
  • One of them which is a vacuum-suction type used frequently in homes, is so designed that a gas current is made to impinge at high speed against a sucked-up liquid stream to thereby atomize the liquid.
  • the other type which is called pressure-feed sprayer which is used frequently in spraying chemical solutions is so designed that two-small sized liquid streams are ejected, under pressure and at high speed, into air with a. predetermined angle relative to each other so that the two jet streams collide against each other to cause the liquid to be atomized.
  • the sprayer of said first type produces relatively fine liquid particles, but in most cases, this is done with a low efficiency.
  • the other type in general, produces larger particles of liquid. Since the sprayer of this latter type is designed so that the liquid streams are adapted to collide against each other outside the nozzles, the ejected liquid will, when ejected at low rate, fall out in drops. Moreover, this latter sprayer has shortcom ings that the control of the conditions such as the shape and the angle of the nozzles and the feed rate of liquid is difficult, and that, for the foregoing reasons, the sprayer requires a structure which is large in scale. Furthermore, where a volatile liquid is contained in a reservoir vessel,
  • Another object of the present invention is to provide a spray nozzle assembly which is applicable not only to a squeezable bottle, but also to a sprayer of the pressurepump type of a large size.
  • Still another object of the present invention is to provide a spray nozzle assembly which, by a mere turning of the cap member, will seal off the liquid contained in the liquid-reservoir and which can be easily controlled of the size of the particles of liquid which is atomized, by a simple manual procedure, namely, by turning the cap of the device.
  • a further object of the present invention is to provide a spray nozzle assembly which has a novel liquid atomizing mechanism and which is capable of ejecting a large amount of finely atomized liquid particles and which permits the user to easily control the diverging angle of the liquid which is ejected through the spray nozzle.
  • Yet a further object of the present invention is to provide a spray nozzle assembly which has a simplified mechanism and which can be manufactured easily.
  • FIG. 1 is a fractional longitudinal cross sectional view of the spray nozzle assembly of the present invention which is in the state of being attached to a squeezable bottle, with the cap being in its closed position;
  • FIG. 2 is a perspective view of the atomizer head which represents one embodiment of the present invention.
  • FIG. 3 is a perspective view of another embodiment of the atomizer head of the present invention.
  • the drawings illustrate the spray nozzle assembly of the present invention which is in the state-of being attached, by utilizing a threaded portion 1a, to a squeezable container 1 made of a synthetic resin or like material.
  • a squeezable container 1 made of a synthetic resin or like material.
  • An atomizer head which is generally indicated at 2 is snappingly attached to a free end portion of the container 1 filled with a liquid for being atomized, by utilizing a projection 5 formed circumferentially on the lower part of the atomizer head cylinder to insure that the head would not come off casually from the mouth of said container 1.
  • the spray head is of a structure comprising a substantially conical-shaped wall member which is so designed as to minimize the pressure of the liquid applied onto the inner face of the wall member, one or more liquid-communicating holes 4 formed through the wall member, a liquid stream revolving portion 3 of a substantially cylindrical shape stemming upwardly from the uppermost end of the conical-shaped wall member, and further a columnar valve member 6 having a semi-globular foremost end and being provided at the upper end of said liquid stream revolving portion 3. As is clearly seen in FIG.
  • the cylindrical liquid stream revolving portion 3 is such that the liquid runs in one direction only and is provided with a plurality of spiral grooves which are three, namely 3a, 3b and 3c in this instance, said spiral grooves being provided with the same pitch and they skirt the periphery of the cylindrical liquid stream revolving portion 3.
  • These three spiral grooves terminate on the end face of the cylindrical portion 3 at such sites that the end face of said portion 3 is divided into three equal sections.
  • the member which is indicated generally by 7 represents a cap which is provided, at the top, with a spray hole 9 which serves also as a valve seat adapted to engage the aforesaid valve member 6 when the cap is closed and further serves as the spray nozzle as a matter of fact.
  • the lower portion adjacent to said hole 9 forms a cavity which surrounds said columnar valve member 6 and constitutes an atomizer chamber 10, from which extends downwardly a bore 8 having an inner diameter slightly larger than the external diameter of the cylindrical liquid stream revolving portion 3. From said bore 8 extends a larger cavity 12 which houses the conicalshaped Wall member of the spray head.
  • the lower part of the inner wall member of the cap 8 is provided with a threaded portion 11 for coupling the cap to either a liquid container 1 or a liquid feed pipe not shown. The mixture of liquid and air is performed sufiiciently in the larger cavity 12 so that outward ejection of liquid is promoted.
  • each of the spiral grooves is of a small cross sectional area which is defined substantially by its own depth.
  • the liquid running through these grooves gains a high speed, and while being passed through the grooves in spiral direction, it is directed towards the exit.
  • the liquid is divided into a plurality of fine streams by virtue of the plurality of grooves, and the fine streams of liquid are made to run spiralwise upwardly along the periphery of the cylinder 3,
  • the running liquid streams take into themselves the air located in the cavity or space of the cap and split into numerous fine particles of liquid.
  • the particles of liquid which have left this part enter into the atomizing chamber where the particles are caused to impinge against each other. While again taking in the ambient air, the liquid particles are further completely atomized into perfectly isolated, individual, extremely fine particles which are then ejected through the spray hole 9. In case the cap is turned through a considerable distance resulting in a greater gap between the valve member 6 and the spray hole 9, the particles of liquid will have a relatively large size and the spray will assume a linear pattern. However, by reducing this gap, the particles of liquid which are to leave from the atomizing chamber 10 will impinge against the valve member 6 and also against the face of the inner wall of the spray hole 9 to thereby be turned into still finer particles.
  • the spray nozzle assembly of the present invention is so designed that the liquid is passed through a plurality of narrow spiral grooves at high speed while taking in air, thus effecting the formation of liquid particles of the first stage; then the particles of liquid thus formed are fed into the atomizing chamber to be mixed with a sufficient amount of air so that substantially complete atomization of the second stage is performed; and furthermore, the atomization of the third stage can be carried out, as required, in the vicinity of the spray hole immediately before the fine liquid particles are ejected therethrough.
  • the spray nozzle assembly of the present invention is completely different from those of the prior art and is based on a novel conception.
  • the spray nozzle assembly of the present invention can be used in many ways. For example, in case it is desired to use this device with a liquid such as perfume, the user will unscrew the cap to an extent that there will be produced a very small gap between the valve member and the spray nozzle so that a wide diverging spray of fine liquid particles may be obtained.
  • FIG. 3 shows another embodiment of the atomizer head of the present invention wherein spiral grooves 3e and 3 which run in opposite directions with the same pitch are provided on the surface of the cylindrical liquid stream revolving portion 3.
  • spiral grooves 3e and 3 which run in opposite directions with the same pitch are provided on the surface of the cylindrical liquid stream revolving portion 3.
  • the spray nozzle assembly of the present invention having the structure illustrated in the drawings bears all of the advantages which have been stated earlier in this specification, and therefore, it should be termed as being an epoch-making spray nozzle assembly.
  • a spray nozzle and cap assembly having axes disposed coaxially and constituting a hollow atomizer head for use on a neck portion of a liquid supply vessel, comprising in combination:
  • a cap member having a generally closed top end and an open skirted lower end, said cap member shaped to freely enclose said conical member in a substantially radially-spaced-apart manner, and to also enclose said skirting member in a constantly but freely slidable engaging manner;
  • said cap member having a spray hole opening axially thereof into the atmosphere and being adapted to be closed by said columnar valve extending thereinto responsive to movement of said cap member relative to said skirting and valve member.
  • a spray nozzle and cap assembly having axes disposed coaxially, and constituting a hollow atomizer head for use on a neck portion of a liquid supply vessel, comprising in combination:
  • a cap member having a generally closed top end and an open skirted lower end, said cap member shaped to freely enclose said conical member in a substantial radially-spaced-apart manner, and to also enclose said cylindrical skirting member in a constantly but freely slidable engaging manner; said cap also including lower peripheral means for engaging said vessel neck on the outer periphery to permit relative axial shifting movement therebetween;
  • said cap having a spray hole opening to the atmosphere axially of the generally closed top end, and said hole being selectively opened and closed by said rounded end of the columnar valve extending thereinto responsive to axial relative movement between said cap member and said valve; and said axial shifting movement of said cap spray hole, end relative to said planar end face and said rounded valve end selectively effects a variable amount and degree of fineness of atomized liquid issuing from said atomizer head.
