KISH ATTORNEY S I United States Patent RELEASE VALVE FOR PRESSURIZED CGNTAINERS Frank A. Ziherl, Cleveland, and Arthur S. Kish, Mayfield Heights, Uhio, assignors to Z and W Machine Products, Inc, Cleveland, Ghio, a corporation of Ohio Application August 12, 1954, Serial No. 449,423
4 Claims. (Cl. 222-394) This invention relates generally to a release valve for pressurized containers, but has reference more particularly to a novel release mechanism or unit for such valves.
A primarly object of the invention is to provide a release valve of the character described, which is readily adaptable for use in conjunction with conventional pressurized containers of a type which is in general use at the present time.
Another object of the invention is to provide a valve opening mechanism or unit which is highly economical in construction, consisting of a minimum number of simple parts, which are easily and inexpensively manufactured, and quickly and easily assembled, without the use of tools or extraneous fastening elements.
Other objects and advantages of our invention will be apparent during the course of the following description.
In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,
Fig. l is a plan view of a pressurized container with a release valve embodying the invention;
Fig. 2 is a view, partly in side elevation, and partly in section, of the container and valve;
Fig.3 is a fragmentary cross-sectional view, on an enlarged scale, taken on the line 33 of Fig. 1;
Fig. 4 is a fragmentary cross-sectional View, taken on the line 4-4 of Fig. 3, and
Fig. 5 is a fragmentary cross-sectional view, taken on the line 55 of Fig. 3.
Referring more particularly to the drawings, reference numeral 1 designates a can, closed at the bottom, as by a bottom member 2, and having a curled or beaded upper end 3, to which a cover 4 is frictionally secured, as by crimping the cover over the end 3, in the manner clearly shown in Fig. 2.
The cover 4 is provided with a base portion 5 which is an integral part of the cover, and has a central circular opening 6, in which the release valve is secured.
The release valve comprises a valve body consisting of a lower member 7, and an upper member 8, which is threadedly secured to the lower member. The lower member 7 is provided with a portion 9 of reduced diameter which extends through the opening 6, and has an annular flange 10 which is riveted or crimped to the lower surface of the base 5 of the cover. A gasket 11 is interposed between the upper surface of the base 5 and a shoulder 12 of the body member 7, to render the connection of the body member to the cover leakproof.
The body member 7 is provided with an axial opening 13, which is counterbored, as at 14-, for the reception of a cylindrical valve housing 15 which is frictionally secured in the counterbore, and has a base flange 16 forming an opening 17. An intake tube 18 is secured to the housing 15.
Disposed within the housing 15 is a valve 19 having a cup-like upper end 2t within which a rubber disk 21 is frictionally secured. The rubber disk 21 is normally maintained seated against an annular rib 22 of the body member 7, a compression coil spring 23 being provided for this purpose, which spring bears at its lower end on the base flange 16 and at its upper end against the end 20 of the valve 19. e
The body member 8, which is preferably molded of polyethylene, is provided with a conical portion 24, through which a passageway 25 for the liquid extends. It is also provided with a web-like central portion 26 having a passageway 27 extending axially therethrough, which passageway is tapered inwardly about 3 from top to bottom. A knife-edge 23 is provided at the lower end of the passageway 27 by molding the wall of the lower portion of the passageway in the manner shown in Fig. 3. The function of this knife-edge will be presently explained.
Above the passageway 25, the body member 8 is also provided with a bracket like extension 29 having grooves 30 in the side thereof, which grooves extend horizontally.
The release valve further includes a stem 31 which extends through the passageway 27 and opening 13 and is several thousands of an inch less in diameter than the diameter of the lower end of the passageway 27, so that the member 3 not only centralizes the stem with respect to the opening 13, but the knife edge 23 always maintain a wiping contact against the stem. The 'stem 31 is of slightly less diameter than that of the opening 13, so as to provide a passageway for fluid between the stem and the wall of this opening. The stem 31 is provided with a head 32 at its upper end.
A handle 33 is also provided, which is preferably formed from a single piece or blank of sheet metal, bent to provide offset parallel portions 34 and 35 and an inclined interconnecting portion 36. A trigger 37 is formed from the blank by shearing the blank to provide a rectangular opening 38 in the portions 35 and 36 and bending the metal from this opening to an angular form, having a rounded bottom 39, which rests on the head 32 of the stem 31, after the handle has been secured to the extension 29 of the body member 8.
The handle is secured to the extension 23 by squeezing the extension 29 through the opening 33 in the handle until the sides of this opening are coplanar with the grooves 30, after which the metal at the sides of the opening will enter the grooves, thus locking the handle against vertical movement relatively to the extension 29. The right end of the opening 38 will then preclude displacement of the handle 33 from the extension 29 by movement to the left, as viewed in Fig. 3, and the end 40 of the trigger 37 will preclude such displacement from the extension 23 by movement to the right, as viewed in this figure.
The operation of the device will be readily understood from the foregoing description.
The can 1 contains a fluid under pressure, and the valve 19 normally precludes escape of the fluid from the can.
When the handle 33 is depressed, the trigger 37 thereof forces the stem 31 downwardly, thereby unseating the valve 19, so that the contents of the can pass upwardly through the tube 18, through the opening 17, through the housing 15, through the space between the stem 31 and wall of the opening 13, into the conical portion 24 of the body member 8, and out through the passageway 25.
The knife-edge 28 exerts a yielding pressure against the stem 31 at all times, and not only wipes foreign particles which might accumulate on this stem, but also forms a fluid tight seal with the stem or precludes escape of fluid through the joint therebetween.
The valve releasing mechanism is highly economical in construction, being made of extremely simple parts which are easily and inexpensively manufactured, and quickly and easily assembled, without the use of tools, or extraneous fastening elements. Moreover, the mechanism is readily adaptable for use in conjunction with conventional pressure spray cans.
It is to be understood that the form of our invention, herewith shown and described, is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of our invention, or the scope of the subjoined claims.
