DISPENSING VALVE FOR A PRESSURIZED CONTAINER Filed June 15, 1953 IN l EN TORS Leo/vaso M. CoLL/Ns United States Patent O DISPENSING VALVE FOR A PRESSURIZED CONTAINER Leonard M. Collins, Los Angeles, and Philip F. George, Arcadia, Calif., assignors to Pressure Dispensers, Inc., Beverly Hills, Calif., a corporation Application June 15, 1953, Serial No. 361,708
8 Claims. (Cl. 222-394) This invention relates generally to dispensing means and more particularly to an improved dispensing valve which is especially suited for use on pressurized containers.
The valve is of the class used on small pressurized containers in which a dispensing nozzle is tilted to effect opening of the valve structure and allow the discharge of the material within the container. Valves of this general type heretofore in use have been very hard to control so as to obtain a regulated ow of material. Excessive displacement of the nozzle is required to open the valve, and the material is dispensed in uncontrolled ow rather than in regulated ow. Furthermore, prior valve structures have' not been suciently positive in sealing to prevent the leakage of the pressurizing gas during storage.
With the foregoing in mind it is a major object of this invention to provide a dispensing valve having positively controlled operating characteristics, and which is especially advantageous for dispensing viscous materials.
Another object of the invention is to provide a nozzle operated dispensing valve which is easily controlled by the use of a slight hand pressure.
It is also an object of the invention to provide a dispensing valve having a free oating valve stem for effecting opening and closure of the valve.
A further object of the invention is to provide a dispensing valve having positive ange sealing means for effecting a seal between the valve structure and the con-l tainer wall.
An additional object of the invention is to provide a dispensing valve having a iiexible grommet and a rigid body locked together in such a manner that the body holds the grommet in tight sealing engagement with the container wall.
Still another object of the invention is to provide a'valve of the character described in which the valve stem and the rigid body cooperate for positive movement. I
upon the operation of the nozzle.
A still further object of the invention is to provide a dispensing valve which is made of a minimum number of easily formed elements so as to be inexpensive in construction.
These and other objects and advantages of the invention will become apparent from the following detailed description of a preferred embodiment thereof, and from an inspection of the accompanying drawings in which:
Fig. l is a perspective view of a pressurized container with an embodiment of the dispensing valve mounted thereon;
Fig. 2 is a longitudinal medial section through the valve taken along the line 2 2 of Fig. l;
Fig. 3 is a view similar to Fig. 2, showing the nozzle tilted with the valve in open position; and
Fig. 4 is a cross-section taken along theline 4-4 of Fig. 2.
Referring now to the drawings and particularly to Fig. 1' thereof, the numeral 10 indicates a container or can which is constructed to hold a quantity of material and a pressurizing gas. Such containers are typically used for dispensing Whipped cream, or the like, with the cream being maintained under high pressure through the use of a compressed gas. The valve herein described is better able to control the flow of fluids having a wide range of viscosities than are the prior valves and accordingl is not limited to any particular application.
In the usual container construction, the container 10 has a top portion 11 having a rolled edge 12 as seen in Fig. 2. A cap 13 is engaged with top 12 by means of a rolled rim 14 which is secured over edge 12 and tightly sealed therewith by a gasket 15. In the center of cap 13 is an opening 16 which is peripherally deiined by a short upturned edge 17 formed integrally with the wall of the cap. A preferred embodiment of our dispensing valve, indicated generally at 18, is adapted to be mounted in the opening 16 to control the flow of material from container 10. As can be appreciated the valve 18 can be mounted in any container opening, the construction of the container shown being merely illustrative.
Valve 18 comprises a resilient grommet 20, a relatively rigid body 21, and a oating valve stem 22 which will be described in more detail. Grommet 20 is adapted to interlock with the wall of cap 13 surrounding opening 16 so as to hold the valve structure in position and is formed of any suitable rubber-like material. The inner portion of grommet 20 is formed with a lower face 23 shaped to provide a valve seat and a frusto conical upwardly tapered ange 24 which seats against the inner face of cap 13. A short cylindrical portion 25 extends through cap edge 17 and joins ange 24 with a somewhat smaller outer ange 26. In assembly, flange 26 is forced through opening 16 to overhang the edge 17 and thus lock grommet 20 tightly to cap 13.
Extending through grommet 20 is an axial bore 28 which opens outwardly through ange 26 and inwardly through valve seat 23. Preferably, bore 28 is joined to seat 23 by a beveled wall portion 29 for better valve operation. Directly above wall portion 29, thewall of bore 28 opens v, into a laterally projecting recess which is in the form of radiused portion 31 joining a straight shoulder 32 as seen -1' il'l Fig. 2.
wardly from the container.
The outer portion of body 21 is formed as an elongated tubular nozzle 36 which has an enlarged bore 37 therethrough joined to the smaller opening through the body by a lateral shoulder 38. At the top or terminal end of nozzle 36 are a series of scalloped serrations 39 which permit the lateral expansion of material as it ows out- The serrations 39 are especially desirable where the container is used for the application of a paste or cream in decorative forms.
At the bottom of nozzle 36 is an external flange 40 which extends outwardly and seats against the grommet locking colar 34 is made shorter than the normal unthe result that both anges 24 and 26 are forced into l( tight sealing engagement with the wall of cap 13. This Thus, the material of grommet 20- container Wall; and a valve stem extended through said body in floating relationship thereto and defining therewith an annular passageway for the flow of material from said container, said stern having a head on the inner end adapted to seal against the inner face of said groin met and a lateral projection on the outer end adapted to engage with the wall of said enlarged bore upon tilting of said nozzle and against said shoulder to limit inward movement of said stern.
6. A dispensing valve for a pressurized container comprisin: a resilient grorn het adapted to be mounted in an opening in said container, said grommet having an inner flange adapted for sealing engagement with the inner face of the container wall surrounding said opening, an outer flange adapted for sealing engagement with the outer face of said wall, an axial bore therethrough with an annular groove extending laterally from said bore within said inner ilange, and an inner face shaped to form a valve seat; a rigid tubular body iitted tightly Within said bore and having a loci-:ing collar seated within said groove, said body having a nozzle portion extended outwardly beyond said grommet with an enlarged bore therein shouldered inwardly adjacent the outer end of said rommet and an external ange seated against said outer gromrnet ange and compressing said grommet :flanges tightly against said container wall; and a valve stern ex tended through said body in oating relationship thereto and dening therewith an annular passageway for the flow or" material from said container, said stem having a head on the inner end adapted to seal against the inner face of said grornrnet and a lateral projection on the outer end adapted to engage with the wall of said enlarged bore upon tilting of said nozzle and against said shoulder to limit inward movement of said stem,
7, A dispensing valve for a pressurized container comprising: a resilient gromrnet adapted to be mounted in an opening in said container and having an axial bore therethrough with an enlarged recess extending laterally from said bore in the portion of said grornrnet inwardly of said opening; a rigid tubular body iitted tightly within said bore and having a locking projection seated within said recess, said body having a nozzle portion extending outwardly beyond said grornnret and said body being seated against the portion of said grommet outwardly of said opening to compress said grommet in sealing en gagement with said container; and a valve stem extending through said body and having a head on the inner end for seating against said grommet.
8. A dispensing valve for a pressurized container comprising: a resilient grommet adapted to be mounted in an opening in said container and having a bore therethrough with an enlarged recess extending from said bore in theportion of said grommet inwardly of said opening; a rigid hollow body within said bore having a projection seated within said recess and a portion extending outwardly beyond said grommet and seated thereagainst to compress said grommet into sealing engagement with said container; and a valve stem extending through said body and having a head on the inner end adapted to close the opening through said body.
