Definitions

  • a miniature type, rechargeable atomizing spray mechanism including a receptacle for the liquid to be atomized, and further including a cap and axially aligned first and second pressure chambers, one of which depends within the receptacle while the other projects above the cap.
  • a reciprocable spray head is arranged to cooperate with plural pistons, one each of which are slidably arranged in said first and second pressure chambers.
  • Upper and lower valve members are available to control the emission of spray. The upper valve is maintained closed by a spring element, and the lower valve is opened by reciprocation of the spray head to permit withdrawal of the liquid from the container so that it may pass through a bore provided between the plural pistons and be emitted as a spray from the spray head.
  • the present invention relates to an atomizer, and more particularly to a miniature atomizer of a manual type for atomizing perfume, cosmetic preparations or the like.
  • a single cylinder is formed midway of a liquid passage extending from a liquid container to a nozzle outlet in an atomizer head.
  • a cylindrical piston which is formed at the lower end of a bored stem depending from the atomizer head, is moved downward within the cylinder.
  • the liquid which has been confined in the cylinder, is permitted to pass through the bore of the stem and then to spurt from the outlet of the nozzle.
  • the liquid thus discharged will be atomized with the ambient air into a desired fine mist.
  • the cylindrical piston is returned or moved upward together with the head by the action of a built-in coil spring so that a vacuum is again established in the cylinder.
  • the vacuum will open a lower one-way valve to admit the liquid from its container into the cylinder.
  • a more specific object of the present invention is to provide a miniature atomizer of manual type, in which both a cylinder of a smaller diameter and a cylinder of a larger diameter are disposed at a lower level and at a higher level, respectively, midway of a liquid passage extending from a liquid container to a nozzle outlet.
  • the two cylinders are made to communicate with each other by way of a tubular sliding member which has a portion acting as a valve member.
  • This tubular sliding member is moved downward only when the pressure in the two cylinders and in the bore of the sliding member exceeds a predetermined high level as a result of the depressing operation of the atomizer head. With the tubular sliding member thus moved, the upper one-way valve is opened to permit the liquid, which has been confined under pressure within the two cylinders and in the bore of the sliding member during the depressing operation, to be discharged through the nozzle outlet.
  • Another important object of the present invention is to provide a manually operated miniature atomizer of the above type, which has such a construction as can scavenge the air which might otherwise be left under a considerable pressure within the two cylinders even after the depression stroke. The air thus left would make it almost impossible to suck the liquid from the container into the two cylinders and so on during the returning upward movement of the tubular sliding member for the subsequent atomization operation.
  • This difficulty is, as is well known, the most prominent when the user buys the miniature atomizer and puts it into actual practice for the first time.
  • FIGS. 1 and 2 are longitudinal sections of a miniature atomizer exemplifying the present invention, the former showing the condition before the atomizer is depressed while the latter showing the condition during the depression stroke;
  • FIGS. 3 to 5 are also longitudinal sections and generally similar to FIG. 1, but show second, third, and fourth embodiments of the present invention, respectively;
  • FIGS. 6 and 7 are further longitudinal sections and generally similar to FIGS. 1 and 2, respectively, but show a fifth embodiment of the present invention.
  • FIGS. 8 to 11 are longitudinal sections showing essential portions of sixth, seventh, eighth and ninth embodiments of the present invention, respectively.
  • a liquid container 1 is formed with a neck portion 2 having an externally threaded portion 3.
  • a cap 4 is formed on the inner face of its lower half with an internally threaded portion 5, which is screwed on the threaded portion 3 of the container 1.
  • the cap 4 is formed integrally with an inwardly extending flange 6 from which a cylinder 7 having a smaller diameter is formed and arranged to depend into the neck portion 2.
  • the cylinder 7 is shown as having a reduced area 7b into which is fitted one end of a suction tube 8 the opposite end of which extends into the bottom of the container 1.
  • the liquid in the container 1 can have operational communication with the inside of the cylinder 7 by way of the suction tube 8 and a first one-way valve 9.
  • a perforated stop plate 11 Disposed on the bottom of the cylinder in the reduced area 7b is a perforated stop plate 11 beneath which is positioned a first valve member 10, preferably of a ball type.
  • the cylinder 7 is arranged to receive a tubular piston 14 which is formed on the outer periphery of a lower portion of a tubular sliding member 13.
  • a perforated stop plate 15 supported on the inward flange 6 prevents the tubular piston 14 from becoming dissociated from engagement with the smaller cylinder 7.
  • the tubular sliding member 13 is formed at the upper portion with a tubular piston 16 and is of a larger diameter than the lower piston 14.
  • the upper surface of the piston 16 is provided with plural projections 17 which in turn support a second valve member 18.
  • this second valve member 18 is positioned above the bore 13a of the sliding member 13.
  • a suitable biasing member such as a coil spring 19, which is operative to bias the tubular sliding member 13 in an upward direction.
  • the atomizer head 20 further includes a cylinder 21 having a depending wall and formed complementally to receive the annulus of the piston 16.
  • the cylinder 21 is provided with an axial aperture or valve passage 22, which is in fluid communication with a nozzle outlet 23 formed on one vertical face of the atomizer head 20.
  • the valve member 18 is chamfered to form a valve seat 24 and is complemental to the means defining the opening 22.
  • a fiuid passage is formed providing communication between the inside of the container 1 and the nozzle outlet 23.
  • the several valves referred to hereinbefore i.e., 9 and 25 thus form a pressure chamber between them when in an operational condition.
  • the first one-way valve 10 is closed by the force of gravity and the second one-way valve 25 is maintained closed by the action of the coil spring 19 all of which is shown in FIG. 1.
  • the cylinder 21 is moved downward together with the tubular sliding member 13, so that the common pressure on the inside of the cylinders 7 and 21 is boosted to an equal level via the bore 13a of the sliding member 13 always providing communication therebetween.
  • the effective area of the piston 16 is greater than that of the piston 14, the downward force to be exerted on the piston 16 is accordingly greater than the upward force on the piston 14.
  • the depressing force to the atomizer head 20 is weakened, the summation of the upward forces of the coil spring 19 and the piston 14 exceeds the downward force of the piston 16 due to the boosted pressure in the confined liquid. Then the second valve member 18 is elevated together with the piston 16 to close the second one-way valve 25.
  • the atomizer head 20 is released from the manual depression at the next stage, the head 20 and the tubular sliding member 13 are returned or moved upward by the biasing force of the coil spring 19 with the second oneway valve 25 being left closed. Since the piston 14 is also elevated at this time, the volume of the pressure chamber is enlarged to change its pressure to a vacuum level.
  • the first one-way valve 10 is opened by the pressure difference between the pressure chamber and the liquid container 1 to allow the liquid in the container 1 to flow into the pressure chamber for subsequent atomization.
  • indicated at refer ence numeral 7a is an opening which is formed in the wall of the cylinder 7 and which acts as an air vent to prevent the liquid container 1 from being excessively evacuated even with the suction of the liquid therein due to the one atomizing cycle.
  • This opening 7a may be desirably formed at such a position as to be opened only when the piston 14 is lowered.
  • FIG. 3 a second embodiment of the present invention will be described and in which like reference numerals will indicate certain parts that correspond to the views of the first embodiment of FIGS. 1 and 2.
  • the cap 4 is not a part of the cylinder 7.
  • a cylinder 6a having an inverted Lshaped cross-section is positioned for support on the flange 6 as shown.
  • the cylinder 21 has a complementally formed L-shaped crosssection 210 which engages the corresponding portion of cylinder 6a.
  • the cylinder 21, which is also made separately from the atomizer head 20, is fixedly inserted in a bore 20b which is formed in an aperture in the head 20.
  • valve passage 22 which is provided in the top wall 216 of the cylinder 21 has its inner lower peripheral edge acting as the valve seat 24.
  • the communication between the bore 13a of the sliding member 13 and the inside of the cylinder 21 is effected by an opening 13b in lieu of use of the projections 17 shown in the drawings of the first embodiment.
  • the sliding member 13 is formed of two concentric elements, as shown, and the coil spring is interposed between the shelf at the bottom portion of the cylinder 7 and the tubular piston 14.
  • the flange 6d of the cap 4 is formed with a stepped tubular portion which includes a guiding cylindrical portion 6/: which extends longitudinally therefrom. From this stepped tubular portion a modified cylinder 26d which includes communicating cylindrical portions 26a and 7b are arranged to extend.
  • the construction of the tubular sliding member 13 of this embodiment is considerably different from those of the first and second embodiments.
  • the sliding member has its lower end portion expanded downward and outward to form the tubular piston 14a and, at its upper end, there is provided a cylinder 21b the upper end of which is open and also is arranged to reciprocate within the cylinder 26a.
  • the inside of the tubular piston 14a and the cylinder 21b are arranged for communication via the passage 13b of the sliding member.
  • the second valve member 18a is formed to extend from the cylinder 21b by means of theprojections 17a. Into this cylinder 21b is inserted the lower end portion of a communication tube 27 which carries the atomizer head 20.
  • this tube 27 is formed with a tubular piston 16a and on the peripheral edge of its open bore with the valve seat 2411.
  • the upper portion of the tubular piston 16a is expanded outward to form an annular wall 1612 which acts to prevent the tube 27, which is inserted into the upstanding collar portion 6b, from slipping out.
  • the tubular sliding member is urged upward by the coil spring 19.
  • the tubular piston 16 is slidably arranged'in the cylinder 21 and surrounds an extension 1812 of tubular member 13.
  • the atomizer head 20 includes a downwardly extending boss 20b the surface of which includes grooves 200 as shown. With such a construction, the groove 200 can provide communication between the sliding bore 13a and the inside of the tubular piston 16 even when the boss 20b is in engagement with the inner periphery of the bore 13a.
  • the atomizing operations of the second, third, and fourth embodiments, as described in the above, are carried out in a similar manner to that of the first embodiment. That is to say, when the atomizer head 20 is slightly depressed, the pressure in the pressure chamber, which is defined by the cylinder 7, the cylinder 21 or 21a and the sliding member bore 13a, is boosted. Thus when the boosted pressure reaches a predetermined level, then the second valve member 18 is moved downward together with the tubular sliding member 13 which carries the piston 14. As a result, the second one-way valve 25 is accordingly opened to permit the liquid in the particular pressure chamber to spurt from the nozzle outlet 23 in the atomized condition by way of the valve passage 22. This atomizing operation will continue while the atomizer head 20 is being depressed.
  • the second one-way valve 25 is closed by the action of the upward biasing force of the coil spring 19.
  • the tubular sliding member 13 is moved upward together with the head 20 to change the pressure in the pressure chamber, i.e., in the cylinder 7 into a negative level.
  • the first one-way valve is opened to admit the liquid into the pressure chamber via the suction tube 8.
  • the present invention eliminates such disadvantages concomitant with the conventional structure as is experienced with liquid injection under insufficiently atomized conditions which comes from the low liquid pressure in the cylinder at the starting and the finishing stages of the depressing stroke of the atomizer head.
  • the constructions of the above type however, one problem is still left unsolved satisfactorily. More specifically, when a miniature atomizer of the above type is used for the first time, the desired atomizing operation cannot be accomplished until the air, which prevails in the pressure chamber defined by the two cylinders and the tubular sliding member 13, has been evacuated or replaced by some quantity of a liquid.
  • the fifth embodiment will be explained with reference to FIGS. 6 and 7.
  • the feature of this embodiment is found in that the first valve member 10a, which has been exemplified as a ball valve in the foregoing embodiments, is formed on the lower end of an elongated stem 30.
  • the upper portion of this stem 30 is so restricted that it can be freely inserted into the bore 13a of the sliding member when the atomizer head 20 is depressed.
  • the lower portion of the stem 30 is formed with projections 30a which may slide within the longitudinal grooves 7b.
  • the grooves terminate at the shoulder portion 7c, on which the coil spring 19 is placed.
  • the stem 30 is retained in the position shown by the engagement of the projections 30a with the lower end of the coil spring 19.
  • a stop 31 may depend from the upper end of the sliding valve member 18d.
  • the inventive concept of the fifth embodiment is to decrease the volume of the cylinder 7 and the bore 13a as much as possible during the depressing stroke of the atomizer head 20.
  • This concept can also be put into actual practice by the miniature atomizer having the following construction.
  • the common feature among the sixth to ninth embodiments resides in that a relief passage is formed between the tubular piston 14 and the cylinder 7 when the atomizer head is depressed its lower limit.
  • a relief groove 32 is formed in the inner periphery of a lower portion of the cylinder 7.
  • a relief groove 32 is formed directly in the cylinder 7 having a unitary structure.
  • another inner cylinder 33 is fitted upward into the smaller cylinder 7 to such an extent as to leave an annular portion acting as the relief groove 32.
  • the cylinder 7 is formed of an upper chamber 7d having an interlocking means provided at its terminus with a means complemental thereto provided on the upper extremity of the member 7d so the elements may be assembled as shown; Thus, the relief groove 32 is retained beneath the interlocking elements.
  • a relief means 35 is formed in a lower inner periphery of the cylinder 7.
  • the tubular piston 14 is moved downward to its lower limit, the outer wall of the piston 14 is partially pushed radially inward by the relief means 35, thus forming around the side walls of the projection 35 a clearance which will act as a relief passage.
  • the atomizer according to the present invention can enjoy the above two advantages, it should further be appreciated that it has such a simple construction as to be fabricated at a considerably low cost.
  • a liquid spraying device comprising a container for liquid, including an axially perforated cap, spray means including a nozzle associated with said container and including reciprocable means extending through said cap, first pressure chamber means depending beneath said cap, second pressure chamber means in axial alignment with said first pressure chamber means and positioned above said cap, said reciprocable means including plural piston members arranged for cooperation with said axially aligned pressure chambers and further including first valve means, said valve means being arranged to control liquid flow from said second pressure chamber to the nozzle of said spray means, spring means arranged to maintain said first valve means in a closed condition to prevent inadvertent emission of liquid therefrom, second valve means in said first pressure chamber means, liquid carrying means depending from said last-named means and extending into said container, whereby upon reciprocation of said spray means said liquid is transported from the container through the axially aligned first and second pressure chambers and emitted from said nozzle.
  • a liquid spraying device as claimed in claim 1 in which further means are provided for controlling the extent of travel of said reciprocable meansv 3.
  • the said second valve means comprises an elongated member extending axially of said first pressure chamber means and further includes means extending into the said bore in said reciprocable means.
