Abstract
A valve device including a valve stem having a flange with a peripheral edge which is received by an annular receiver which constitutes a separate part of the valve device. The annular receiver has a seat receiving a peripheral edge of the flange, and either the flange or the seat has at least one, and preferably a plurality of openings therein allowing pressurized contents of the container to reach a space between the flange and a sealing ring against which a sealing portion of the valve stem is biased. The interior of the valve stem is blocked, but a hollow portion of the valve stem has at least one opening therein within the sealing ring and normally blocked by the sealing ring. When the valve stem is depressed, the sealing ring bends to uncover the opening, thus allowing container contents to be discharged. The flange is distorted and due to the resiliency or elasticity thereof, it returns the valve stem to its valve-closed position.

Before explaining the present invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and arrangement of parts illustrated in the accompanying drawings, since the invention is capable of other embodiments and of being practiced or carried out in various ways. Also, it is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation.
AS SHOWN ON THE DRAWINGS Referring first to FIGS. 1 through 6, there is shown a portion of a container having a valve device 22 mounted at the top thereof for use in discharging the pressurized contents of the container. Such a valve device is often known as an aerosol valve, but it may be used for purposes other than aerosolizing; e.g., to dispense foam or a liquid stream.
The valve device 22 includes a partly hollow valve stem 24 which has a flange 26 projecting radially therefrom and molded as one piece with the valve stem 24. The interior of the valve stem 24 is hollow except where it is blocked by a blocking portion 28.
Just above the blocking portion 28,'there is an opening or a set of openings 30 through the sidewall of the valve stem 24. These openings lie within the inner edge 32 of a sealing ring or washer 34, and the edge 32 of the washer normally blocks the openings 30. The valve stem 24 has a sealing portion in the form of a shoulder 36 which butts against the sealing ring 34 to provide a seal for preventing the pressurized contents of the container from reaching the openings 30 when the valve is in its valve-closed position as shown in FIG. 2.
The peripheral edge of the flange26 is received on a circular seating surface 38 on a receiver member 40 which is a separate plastic part of the valve unit. The receiver element 40 is hollow, and held by a metal retainer 42 which is swedged at 44 so as to press the retainer element 40 upwardly against the sealing ring 34 to provide a good seal where the upper edge of receiver element 40 meets the sealing ring; The metal retainer 42 is attached to the top of the container 20 at a sealed joint in order to attach the valve device to the container.
When the valve device 22 is fully assembled as shown in FIG. 2, the flange 26 is flexed or distorted slightly so as to bias the seating shoulder 36 against the sealing ring 34. The flange 26 has a plurality of apertures 46 therein for allowing the pressurized contents of the container to reach a space 48 between the flange 26 and the sealing ring 34.
The receiver 40 has a reduced portion 50 at the bottom end thereof which forms a tube to which a dip tube 52 is attached. The dip tube 52 extends downwardly into the container to a point near the bottom thereof so that the pressurized contents of the container will be forced through the dip tube into the valve device. The receiver 40 is stationary, but the valve stem 24 is movable relative to the receiver. The receiver 40 has a stop surface 54 at the top of tube portion 50 which stops the bottom edge 56 of the valve stern 24 during its downward travel so as to limit the downward movement of the valve stem. The movement of the valve stem is guided by ribs 58 formed on the inside of the receiver 40 and spaced about the inner perimeter of the receiver so as to be slidably engaged by the sidewall of the valve stem 24. The bottom edge of the valve stem has recesses 60 therein which permit pressurized contents of the container to flow into a space between valve stem 24 and receiver 40 even when the valve stem 24 is fully depressed so that the bottom of the valve stem butts against the stops 54.
The valve device is shown in an actuated or valve-open position in FIG. 5. It may be seen that the valve stem 24 has been depressed, and a slanting circular surface 62 on the valve stem has pushed the sealing ring 34 downwardly so as to bend the sealing ring away from the openings 30, thus uncovering these openings. The bottom of the valve stem butts up against the stop surface 54.
With the valve in the position shown in FIG. 5, the pressurized contents of the container flow through the dip tube 52, the tube portion 50 of receiver 40, then recesses 60, the spaces between the ribs 58, the space between valve stem 24 and the inner wall of receiver 40, the openings 46, the space 48, the openings 30, and the space within the upper part of valve stem 24 to a small opening 64 in a valve cap 66 which is attached to the top of the valve stem 24. The container contents are discharged as an aerosol through the very small opening 64 in the manner illustrated in FIG. 5.
When the valve stem is released, the resiliency or elasticity of the flange 26 causes the valve stem 24 to return to the valve-closed position as shown in FIG. 2. This blocks the openings 30 to again prevent the pressurized container contents from escaping from the valve.
FIGS. 7 through 11 show another embodiment of the invention which is very similar to the embodiment of FIGS. 1 through 6, so the same reference numerals have been used for like parts. One difference of the valve of FIGS. 7-11 from that of FIGS. 1-6 is that the outer peripheral edge of the radial flange 26 is seated on a seating surface 38 which has a plurality of grooves or notches 39 formed therein to provide a path for allowing the pressurized container contents to reach the space 48 between the flange 26 and the sealing ring 34. Thus, it is not essential to provide openings such as the openings 46 of FIGS. 2 and 5 in the flange 26.
Another difference of the valve device of FIGS. 7 through 11 as compared to that of FIGS. 1 through 6 is that the seating surface 36 is on a flange 37 which projects outwardly from the valve stem 24. Another difference is that bottom end of the valve stem 24 is completely closed or has no hollow interior, but it is still received within a hollow portion of the receiver 40 near the bottom thereof. A stop surface 54 is still provided on the interior of the receiver 40 near the bottom thereof to limit the downward movement of the valve stem 24. The ribs 58 of FIG. 2 have been omitted, but it should be understood that such ribs could be provided if desired. The bottom portion of the receiver 40 has a cross-sectional shape that is shown in FIG. 10 wherein there are small projections 70 against which the bottom of the valve stem 24 abuts when the valve stem is fully depressed. The space around these projections 70 allows the pressurized container contents to enter the space between receiver 40 and valve stem 24 when the valve stem is fully depressed in the manner shown in FIG. 11.
The construction and operation of the valve device of FIGS. 7 through 11 is otherwise substantially the same as that of the valve device of FIGS. 1-6 and consequently the description of construction and operation will not be repeated.
