Oct. 16, 1951 R. MORRIS V ATOMIZER OF SINGLE PIECE CONSTRUCTION Filed une 2, 1948 Patented Oct. 16, 1951 QEFICE stowa N LE meg This invention relates .to at particularly'lto atom'iz'ers jfis" tmfsl .r I
An object of .this invention is to provide an atomiii'ng orspray'iiead unit which is inserted I. assa es;
in a flexible containerand whereinthe sprayin arid self contained.
Another object is to provide an atomizer wherein, having a fleSEible cofitaIfii, air conmined in the unit is utilized for atomizing Ythe iqui b 's re sure 9f .ihes fi sle the 9 he?! e u therwiecifpfih s iti i P?;- ride a one part stray heed Me ts Y a ont i e -usi the 13 2 eesyi wil need t s with one an on Anaddition al o b ect of h s nvention is to provide an atomizer wherein the atomizing head unit is inserted in a container under 1 116551126 thus reducingpossibility 10f adulteration .of the contentsbyremoval of -the head unit.
' other objects .and .purposes .of i'the invention will be apparent from the following detailed description of one preferred embodiment thereof when taken with the drawings in which:
Fig. 1 is a sectional view taken through an atomizer head unit as applied to a medicament or liquid container,
Fig. 2 is a partial sectional view taken on the line 2-2 of Fig. 1, and
3 is a side elevational view of the atomizer, parts thereof being broken away for clarity.
In the drawings the same reference characters are used to indicate similar parts.
As will be seen by referring to the drawings, a container I is provided and which is constructed of a flexible material such as a plastic or other suitable substance which will be unaffected by medicaments contained therein. The container I has a thickened neck portion 2 on the outside of which may be arranged screw threads 3 for the purpose of threading thereon a closure member, not shown, to insure no leakage from the container and also for sanitary reasons.
In the container there is a medicament or other liquid of any desired type to be sprayed, designated as 4.
The mouth 5 of the container may if desired be shaped with inwardly sloping side walls as shown in the drawings but this is a matter of choice.
Inserted in the mouth 5 is an atomizing or spraying head unit 6 having a flange 1 formed thereon which abuts against the top of the container at the mouth 5. This unit '6 may also be with the atmosphere and forms the outlet for the atomized medicament or liquid. In the bore III are grooves IE on diametrically opposite sides which extend along the side of the bore I0, opening into the annular chamber I2 and through chamber I2 into the mixing chamber I3 as shown in Figs. 1 and 2.
Inserted in the bore I0 is a tube It of any suitable material which is impervious to the medicament or liquid in the container I. The upper end of tube [6 abuts against the shoulder H and extends down into the container I and rests on or is in close proximity to the bottom thereof. As is shown in Fig. 1, the grooves I5 extend beyond the upper end of the tube It for a purpose to be later described.
Having now described the construction of the present device, it is deemed desirable to set forth the method of operation thereof.
The tube It is pressed into the bore Ii] until it abuts the shoulder II. The container I is then partially filled with a medicament or other liquid material 4 which it is desired to atomize or spray. The entire spraying head unit 6 together with the tube I6 is inserted in the mouth 5 of the container I and pressed therein until the flange I abuts against the top of the container. The tube I6 will then extend into the liquid 4. Now the entire unit is assembled and when the flexible sides of the container I are pressed into a position simhand. The construction of the atomizer is simple;
sturdy, and inexpensive to manufacture. It is understood that although a single preferred embodiment of the invention has been described for purposes of illustration that changes and modifications may be introduced with regard to certain details of construction and shape of the atomizer, without departing from the basic principles of the invention. f K
1. An atomizer comprising a flexible container adapted to hold a liquid and having an opening therein, a single piece elastic atomizing head unit inserted in said opening, said head unit having a central circular depending portion thereon, a tube inserted in a central bore in said depending portion of said head unit and extending into liquid contained in said container, diametrically opposed grooves in said depending portion of said head unit contiguous with said tube in said central bore, a cylindrical chamber in said head unit above said tube, said tube opening into said cylindrical chamber, a mixing chamber in said head unit above said cylindrical chamber and emerging therefrom, said grooves in said unit extending from the lower extremity thereof to said cylindrical chamber opening thereinto and through said chamber opening into said mixing chamber, and said head unit having a spray out- 4 mixture will be forced from said spray outlet as a fine spray.
2. An atomizer comprising a flexible container adapted to hold a liquid and having an opening therein, a single piece elastic atomizing head unit inserted in said opening, a spray outlet in said head unit, a mixing chamber in said head unit communicating with said spray outlet, a cylindrical chamber in said head of larger diameter than said mixing chamber and communicating therewith, a central depending portion in said head unit having a central longitudinal bore therein, said bore opening into said cylindrical chamber, diametrically opposed grooves in said head unit adjacent said bore and opening into said cylindrical chamber at one end thereof and extending along said bore into said container, a tube in said bore communicating with said cylindrical chamber and extending into liquid in said container whereby liquid and air may be forced from said container to said mixing chamber and the atomized mixture forced from said spray outlet.
let therein connected to said mixing chamber whereby upon squeezing said container liquid will flow through said tube and be mixed with air flowing through said grooves and the atomized REFERENCES CITED The following references are of record in the file of this patent:
