ALL-DIRECTION ATOMIZERS The present invention relates to atomizers of the squeezebottle type, for perfumes, cosmetic and pharmaceutical solutions, and other liquids.
Heretofore, this class of atomizers operated properly only if held erect or sightly inclined to vertical, for lateral or upward discharge, depending upon the discharge orifice direction the device was designed for. At other positions at variance with the upright, especially when the device was held to discharge downwardly in any direction which might be true vertical or slanted, the emission of liquid was not an atomized spray, but a thin continuous stream. At many positions in hand, there would be no discharge at all.
It is therefore the principal object of this invention to provide a novel and improved squeeze-bottle-type atomizer construction, which will discharge an atomized spray in any direction desired, depending upon its position in hand.
A further object thereof is to provide a novel and improved atomizer of the character described, which is of simple construction, reasonable in cost to manufacture, all parts of which may be molded of plastic and easily assembled, simple to use, positive in action and efficient in carrying out the purposes for which it is designed.
Other objects and advantages will become apparent as this disclosure proceeds.
For one practice of this invention, there is an elongated stopper fitted in the neck of an elongated resilient squeeze bottle, and said stopper extends downwardly in said bottle to a predetermined level. The stopper at its upper end region, has a slight internal chamber whose upper wall has an upward discharge orifice. The capillary upper end of an air duct, and the upper end of a capillary liquid duct, extend from the lower wall of said chamber and are respectively communicative with said chamber. Said ducts extend longitudinally along and within said stopper body, and open at the stoppers lower end. However, the lower end of the liquid duct has a communicative tubular extension downwardly therefrom so the lower open end of said extension is very near the bottles floor. The liquid duct also has a branch along itself in the stopper body, the lower end of which branch extends from and is connected to said liquid duct near the bottom end of the stopper, while the upper end of said branch extends to the bottles neck region where it is communicative with the bottles interior. A desirable, but optional openwork element extending downwardly from the stopper, limits the extent the bottle can be collapsed when squeezed at its lower region; the diameter of the stopper being sufficient to limit the collapse of the bottle when squeezed at its middle or upper regions. The lower end of the air duct, meaning the open end of the air duct within the bottle, is always above the liquid in the bottle, regardless of the position of the bottle, when squeezed or not squeezed.

In the drawing, the numeral 15 designates generally a resilient squeeze bottle molded of a plastic as polyethylene or of rubber, preferably with a neck 16, fitted with an elongated stopper denoted generally by the numeral 17 which extends downwardly into the bottle a predetermined distance. Said stopper is provided with an air duct 18, and a capillary liquid duct 19 close alongside each other, both of which start open at the lower end of the stopper and extend upwardly therethrough when they are communicative with a slight mixing chamber 20 within the upper region of said stopper. The air duct 18 discharges against the ceiling 21 of said chamber to one side of a central, vertically upward discharge orifice 22, which is in registry with the upper end of the liquid duct 19; the upper ends of said ducts being extremely close to one another. The upper end of the air duct is reduced to capillary size as shown at 23. The open lower end of said air duct is indicated by the numeral 24. The lower end of the liquid duct 19, has a downwardly tubular extension 25, reaching very close to the bottom of the bottle. Some bottle shapes require an openwork structure which may be a perforated tube 26, which extends downwardly from the stopper body, reaching close to the bottom of the bottle. The liquid duct 19 has a branch 27 spaced therealong in the stopper body, extending upwardly from its connection 27 to said liquid duct, which is near the lower end of the stopper, to near the neck region of the bottle, where said branch opens at 28 to be communicative with the bottles interior.
Suggested dimensions for the capillary ducts 19, 27 and 23, is one thirty-second of an inch in diameter, and for the air duct 18, a diameter of one-sixteenth of an inch.
A practical and preferred manner of stopper construction, is to make it of three molded plastic parts. These are indicated by the numerals 29 and 30, which are semicylindrical pieces of equal size, and the third part 31 is an inverted cup of some resilient quality, having a flange to form a head 32 at its closed end. The parts 29, 30 are formed with channels in their respective flat faces, one right and the other left, so when placed with such faces in contact and cemented together or otherwise joined in such relation, the channels in one, match the channels in the other, to form the air duct 18 with its reduced end 23, the fluid duct 19, and the branch 27 respectively. The cup 31 has a central discharge orifice 22 through its head 32, which hole is provided with a slight counterbore 20' of a depth of capillary dimension within the cups interior. Said cup is set as a cap onto and in contact with the upper end. of the cemented cylinder form made of 29 and 30, and cemented thereto. Thus attaining a stopper of unitary structure; the mouth of the said counter bore 20' being thus closed to form the mixing chamber 20. When the said stopper is set into the bottle so its head 32 rests against the bottles mouth rim as shown in FIG. 1, said head will serve as a stop to assure the proper position so that the open end 24 at the bottom of the air duct, shall be its necessary distance from the bottles bottom, and the bottom is tightly corked" by the cap 31.
For the proper operation of this atomizer 33, it is necessary that the lower open end 24 of the air duct 18, shall at all times be above the supply of liquid 34 in the bottle 15, regardless of the position of the bottle, when squeezed or not squeezed. It is to be noted that when the bottle is squeezed, the level of the liquid 34, will in many instances rise a bit. The extent to which the bottle can be collapsed by a squeezing action done by pinching opposite wall sections, might be limited by the nature of the material it is made of, by the shape of the bottle, by the stiffness of its floor and ceiling walls, by the diameter size of the stopper 17, and as may be necessary in some constructions where the bottle is rather soft, by the inclusion of a rigid spacer means as for instance the perforated tubular extension 26. The initial supply of liquid in the bottle is therefore limited to attain the conditions aforesaid which are necessary for the atomizer to function properly. It is evident that the largest permissible liquid supply shall be less than half the available volume of the bottle 15, and that the stopper 17 shall be of a length to extend into the bottle so the available volume in the bottle which encircles the periphery of said stopper shall be more than half the total available volume in the bottle, and that the open end 24 of the air duct shall be above the liquid's level when the atomizer is positioned erect as in FIG. I, and squeezed to the greatest extent possible, at opposite wall regions of the lower part of the bottle, and also that said open end 24 shall be above the liquids level when the atomizer is held horizontalas in FIG. 3, and squeezed to the greatest extent possible to make the liquid level rise.
After the bottle is filled with liquid to the extent mentioned as indicated by the level L, and the stopper I7 is tightly fitted so the atomizer device 33 is in condition as shown in FIG. ll, its operation is as follows:
Holding the bottle erect in hand, it is pinched to collapse, and released to expand back to normal. The air within the bottle is thus compressed, and an airflow is caused to flow upward through the air tube 18, and its velocity is increased as it passes through the reduced upper portion 23, from which it impinges against the ceiling 22 of the chamber 20, which deflects it to move across the upper open end of the liquid tube 19, creating a vacuum condition in the liquid tube. The pressure differential causes the liquid to rise up the liquid tube 19, and the continuance of the air flow caused by a repeated pinching action, will cause the liquid coming to the top of the liquid tube, to be atomized, in which state it will discharge upward through the orifice 22 as a finely divided spray. If the atomizer 33 is tilted, as for example to the position shown in FIG. 2, the level of the liquid will be at L. When operated in this position, the spray discharged from the orifice 22, will be tilted. The extent of tilt may be at any angle in relation to vertical, up to horizontal position as shown in FIG. 3. When the position is true horizontal, the liquid housed in the liquid tube 15, will be atomized upon squeezing the bottle and discharged horizontally. The unsteadiness of the hand, will cause enough oscillations to bring more liquid into the liquid tube, for continued operation. The tilt may be to the right or to the left.
Squeezing the bottle when it is held in hand in inverted position as in FIG. 5, where the liquid level is at L, liquid is drawn into the the liquid tube 18, through its branch 27, whose intake opening 29 in is the liquid. Discharge will be due downward. If the atomizer is tilted, as for example to the position shown in FIG. 4, the level of the liquid will be at L"". When operated in this position, the spray discharged through the orifice 22, will be tilted. The extent of tilt may be at any angle in relation to vertical, up to horizontal position. The tilt may be to the right or to the left.
