Definitions

  • a negative pressure chamber encloses the spray nozzle in order to commingle dosed directed air with the spray jet coming from the spray nozzle.
  • a spray jet discharge tube is provided at the negative pressure chamber and such discharge tube is located in front of the nozzle opening and at least approximately in alignment with its spray jet.
  • An air infeed channel faces away from the spray nozzle and such air infeed channel is approximately aligned with the spray jet. Further, means are provided which are actuatable lby the actuation member or formed by the latter and which permit regulation of the quantity of air which is sucked through the air infeed channel.
  • the present invention relates to an improved actuation mechanism which can be mounted upon a spray can, this actuation mechanism being of the type incorporating an actuation member which acts upon the valve knob of the spray can which is constructed as a spray nozzle.
  • Another, more specific object of the present invention relates to an improved actuation mechanism for a spray can which enables achievement of quite favorable spray conditions in a controlled manner.
  • Still a further significant object of the present inven- Patented Mar. 17, 1970 tion relates to an actuation mechanism which can be detachably secured to a spray can and possesses a safety feature which is especially important if the spray can should accidentally come into the hands of children or other persons who are not familiar with its operation.
  • the aforementioned objects of the invention can be eifectively realized by the provision of the inventive actuation mechanism of the aforementioned type which is characterized by the features that there is provided a negative pressure chamber which encloses or encircles the spray nozzle in order to commingle dosed directed air ⁇ with the spray jet emanating from a nozzle opening of such spray nozzle.
  • a spray jet discharge tube is provided at the negative pressure chamber and such discharge tube is located in front of the nozzle opening and at least approximately in alignment with its spray jet.
  • An air infeed channel faces away from the spray nozzle and this last-mentioned channel is at least approximately aligned with the spray jet.
  • the invention further contemplates the provision of means which are actuated by the actuation member for the spray nozzle or itself formed by such and which enable regulation of the quantity of air which can be sucked through the air infeed channel.
  • actuation member is defined -by a lever which is arranged in the air infeed channel.
  • This lever then forms a wall portion of the channel, so that it is not only possible to control the channel cross-section, but rather also the direction of the air moving out of this channel and arriving at the spray nozzle.
  • This impact member should be adjustable so that once the optimum valve opening has been determined it can be positively set so that during repeated actuation of the spray nozzle the user is ensured of achieving exactly similar results. Additionally, this impact member can be constructed in such a fashion that it can completely lock the actuation lever, and furthermore, the force necessary to carry out unlocking of this lever can be calculated such that it cannot be applied by a small child. As a result, there is provided an especially attractive safety feature for children in particular.
  • the spray jet discharge tube is constructed to be adjustable or exchangeable, or if there is provided insert members for the spray jet discharge tube which are adjustable or exchangeable, then it is possible to adapt the device particularly Well to the purpose at hand. This is so because the negative or reduced pressure in the nega tive pressure chamber which appears because of the ejector action in the discharge tube, is dependent upon the dimensions and the mutual position of the discharge tube and the spray jet. Naturally, the infed air also plays a certain role.
  • a compensation chamber which advantageously is arranged about the negative pressure chamber and communicates with the latter as Well as with the external air, ensures a still better admixture of air with the spray jet. It also provides the advantage that a dripping of the nozzle is prevented. Apart from this, it is possible to effectively accomodate for the drop in pressure in the can which occurs during use.
  • annular compartment which is formed between the concentrically arranged negative pressure and compensation chambers advantageously corresponds to the annular bead which with conventional spray cans extends about the nozzle member, and thus it is possible to mount the apparatus upon this annular bead.
  • inventive apparatus or mechanism can be formed of any desired type material, for instance plastic.
  • FIGURE l schematically illustrates the head of a spray in which is not provided with any cap mem-ber
  • FIGURES 2 and 3 schematically depict the head of a :spective spray can provided Iwith two different construcons of cap member in order to explain the effect of such 1p members;
  • FIGURE 4 shows a possibility of partially overcoming 1e drawbacks which appear with the spray can of FIG- IRE 3 which is provided with a cap member;
  • FIGURES and 6 schematically illustrate a spray can quipped with an actuation mechanism of the type proided for by the teachings of the present invention, and :rve to explain the principles of the invention
  • FIGURE 7' is a perspective view of an actuation mechnism designed according to the invention.
  • FIGURE 8 is an exploded view of the inventive actuaon mechanism shown in FIGURE 7.
  • a spray can 1 equipped with a valve ozzle head or spray nozzle 2 having the usual nozzle pening, as shown, for the efflux of the spray jet 4.
  • a valve ozzle head or spray nozzle 2 having the usual nozzle pening, as shown, for the efflux of the spray jet 4.
  • an anular bead or projection 3 At the pper region of the spray can 1 there is provided an anular bead or projection 3. The entry of air is indicated y the arrows. Since the air has free access in an unconolled and undirected manner, it is not possible to obtain 1e best results.
  • FIGURES 5 and 6 the basic principles of the resent invention are illustrated in accordance with a preerred embodiment.
  • a cap iember 5 or 5 or 5 as shown in FIGURES 1 to 4, and /hich is seated upon the annular bead 3
  • a cap member 7 which engages the annular bead l at the inside by means of the claw members 7 and orms a negative or reduced pressure chamber.
  • the cap member 7 is provided with a spray jet discharge tube 8 hrough which escapes the spray jet 4, whereas air can nter the negative pressure chamber by means of the air lfeed channel 6, this air flowing in the direction of the ndicated arrows.
  • FIGURE 6 As best recognized by inspecting FIGURE 6, to provide n improved accommodation of the spray jet discharge tube 8 to the spray jet 4, it is possible to mount an insert member 8 in the discharge tube 8.
  • This insert member 8' can be, for instance, adjustably positionable with respect to the spray nozzle 2 by providing suitable threading. Furthermore, it is possible by selecting a suitable insert member 8 having an appropriate diameter to also vary the ejector effect. Furthermore, as has been previously explained, it is conceivable to also make the discharge tube ⁇ 8 adjustable or exchangeable.
  • the air infeed channel 6 is not directly connected to the negative pressure chamber in the cap member 7.
  • this air infeed channel 6 is secured to an external cap member 5" which is arranged concentrically about the inner cap member 7.
  • Thisy external cap member 5 corresponds to the cap members 5, 5 and v5 reviewed in connection with FIGURES 2 to 4.
  • the inner cap member 7 is provided with a suitable window or opening 7 to enable the entry of air coming from the air infeed channel 6.
  • the described construction also provides for a compensation chamber which is formed by the annular compartment located between the internal cap member 7 and the external cap member 5".
  • this annular compartment between the cap members 7 and 5 allows air to not only enter through the channel 6, but also beneath the discharge tube 8.
  • This annular copartment renders possible an improved accommodation of this inventive apparatus to the variable operational conditions or requirements, as such have already been considered.
  • the spray jet discharge tube 8 with its possible insert means 8 not only has the job of improving the ejector effect, but also must conduct the spray jet 4 together with the infed air through the cap member 5" in order to prevent any turbulence.
  • FIG. URES 7 and 8 The attachment mechanism which has been illustrated in FIGURE 6 has been shown in greater detail in FIG- URES 7 and 8, and more specifically, in the form of a pistol-like handle assembly.
  • FIGURES 7 and 8 there will be recognized for the rst time the actuation lever 9 which is located in the channel 6.
  • This actuation lever 9 includes a lever arm 9 which operates the spray nozzle 2 and simultaneously serves as a movable regulation member for controlling the cross-section of the channel 6.
  • the walls of the channel 6 are provided with bearing supports 10 capable of receiving the pivot shaft means 10 of the actuation lever 9.
  • this actuation lever 9 also includes a trigger portion 9".
  • a certain negative or reduced pressure is likewise produced in the annular compensation chamber located between the cap members 7 and 5". This serves to equalize or compensate the air which arrives at the annular compensation chamber above the lever arm 9 as well as also to compensate the air which enters beneath the spray jet discharge tube 8.
  • a compensation action is provided which accommodates the different operational phases (such as starting, full operation, and stopping of the spraying activity) and further accommodates for the dropping pressure in the spray can 1 which occurs during use.
  • FIGURE 8 shows the inventive actuation mechanism of FIGURE 7 in an exploded view with the exception of the inner cap member 7 which is normally located in the external cap member 5".
  • the air infeed channel 6 the walls of which are provided with the bearing slots 10 for the pivot shaft means 10 of the actuation lever 9 which includes the lever arm 9 and the trigger portion 9".
  • the cover member 6" of the inventive illustrative embodiment of actuation mechanism there are provided two rib members 12 which can be inserted in guides 12 provided Yat both sides of the channel 6.
  • the recess 19 for receiving the trigger portion 9 of the actuation lever 9 is shown in phantom lines in FIGURE 8. Furthermore, it should be understood that the wall portions which extend from the handle 6' up to the cap member 5" have only esthetic and functionally anatomical significance. It would be readily possible to connect the handle 6 directly to the channel 6.
  • the cam 14 of a curved or cam plate 13 can be inserted through a slot 14 from inside of the handle 6' and held in such position by any suitable means, for instance a spring.
  • This cam plate 13 possesses, in addition to the for instance curved steep plane surface 13', a grooved portion or groove 13". lf the cam 14 is located at the lowermost position of the slot 14, then the trigger portion 9" of the actuation lever 9 can be freely depressed. The higher that the cam 14 is upwardly displaced, the less it is possible to depress the trigger portion 9" of the actuation lever 9 because it comes to bear with its rear edge 15 against the steep plane surface 13.
  • An actuation mechanism for ⁇ attachment to a spray can havlng a valve knob member constructed as a spray nozzle provided with a nozzle opening comprising an actuation member for actuating the spray nozzle, means providing a negative pressure chamber enclosing the spray nozzle in order to admix dosed directed air with the spray jet emanating from the nozzle opening of the spray nozzle, a spray iet discharge tube provided at said negative pressure chamber, said spray jet discharge tube being disposed in front of and spaced a substantial distance from said nozzle opening and at least approximately in alignment with its spray jet, means defining an air infeed channel facing away from said spray nozzle and communicating with said negative pressure chamber, said air infeed channel being at least approximately aligned with the spray jet, and means for regulating the quantity of air which can be sucked through said air infeed channel.
