J., assignor, by direct and ruesne assignments, to Oil Equipment Laboratories, Incorporated, Elizabeth, N. J., a corporation of New Jersey Application November 9, 1953, Serial No. 390,831 18 Claims. (Cl. 222-41) The present invention relates to a combined dispenser and mechanism and relates, more particularly, to a combined dispenser and valve operating mechanism for a pressurized container.

An object of the present invention is to provide a combined dispenser and valve operating mechanism for controlling the operation of a valve in a pressurized container. A further object of the invention is to provide a combined dispenser and valve operating mechanism which may be rendered operative or inoperative by a simple adjustment. A still further object of the present invention is to provide a combined dispenser and valve operating mechanism which may be manufactured at a relatively low cost.

Other objects and advantages of the invention will be apparent and best understood from the following description and the accompanying drawings in which:

Referring to the drawings in detail there is a pressurized container 11 of a type commonly used for packaging and dispensing a wide variety of commodities such as shaving soap, cosmetics, insecticides, paints and the like.

The container 11 consists of a can body 12 having the usual opening in the top thereof with a closure member 13 secured in the opening. The closure member is secured to the can body by crimping the outer edges of the closure member 13 over a bead which surrounds the opening in the top of the can body, as indicated at 14. The closure member 13 has an opening therein in which a valve mechanism, indicated generally at 15, is located. The operation of the valve 15 controls the discharge of the contents of the container and in addition, the container may be filled with gas under pressure through the valve mechanism 15.

The valve mechanism 15 illustrated in Fig. 3, consists of a tubular valve body 16, the top half of which is formed by the closure member 13 and the bottom half of which is formed by a retaining cup 16a secured to the closure member. The tubular valve body 16 has a centrally apertured valve seat 17 located at the top end thereof and has an opening at its lower end communicating with the interior of the container. The lower end of the valve 2,752,066 Patented June 26, 1956 body is constricted to form a seat for a valve spring 18 and to receive a siphon tube 19 which extends into the container. The valve spring 18 engages with the base of a tubular valve stem 20 and urges the valve stem upwardly in the valve body with the top of the valve stem projecting through the aperture in the valve seat. The action of the spring on the valve stem urges a washer 20a of compressible material carried by the valve stem into engagement with the valve seat. To open the valve, the valve stem is depressed against the force of the spring and the washer is moved out of engagement with the valve seat. Such a valve mechanism is described and claimed in United States Letters Patent Nos. 2,667,993 and 2,670,106, entitled Pressurized Container Valves and Multi-Purpose Pressurized Container Valves, issued to.

me on February 2, 1954, and February 23, 1954, respectively, and reference may be made to said patents for a more detailed description thereof.

The closure member 13 has a depressed portion forming a recess or cavity in the top thereof and a combined dispenser and valve operating mechanism, indicated generally at 21, is seated in such recess or cavity. The entire dispenser and valve operating mechanism may be molded from a suitable plastic material such as polyethylene which is resilient and hence compensates for any slight inaccuracies in the sizes of the various parts while providing a snug fit.

The dispenser and valve operating mechanism 21 consists of two parts, a base 22 and an operating member or cap 23 which is rotatably mounted on the base 22. The base 22 has an opening 24 extending therethrough which fits over the top of the valve body and the valve stem extends through the opening when the base is installed on the closure member 13. Extending outwardly from the sides of the base there is a downwardly extending flange 22a which fits over the bead formed at the point where the closure member is secured to the body of the container and snugly engages therewith.

The cap 23 which is rotatably mounted on the top of the base 22, contains a discharge passageway 25 having an outlet in the side of the cap. The discharge passageway 25 communicates with a flexible sleeve 26 extending downwardly from the bottom of the cap. The sleeve, which may be formed as part of the cap, fits into the opening 24 in the base and communicates through the opening in the base with the valve-controlled opening in the container. The sleeve extends into the opening in the base and has an outwardly projecting lip 27 surrounding its lower end which engages with a shoulder 28 in the sidewalls of the opening 24 to secure the cap to the base. The cap can be assembled in the base by forcing the sleeve into the opening in the base.

When the valve stem is depressed, the contents of the container are discharged through the opening in the base to the flexible sleeve 26 and thence, to the discharge passageway 25. In passing through the flexible sleeve, the pressure of the contents being discharged acts against the interior of the flexible sleeve and urges the sleeve into engagement with the sides of the opening in the base. This forms a seal between the cap and the base and prevents leakage of the contents between the base and the cap.

A valve operating member in the form of a downwardly on in the form of an annular rig 36 on the top of the base which fits into a groove 31 in the bottom of the cap. The

top surface of the rib 3i) and the bottom surface of the groove 31 are in opposing relation and have matching cams formed thereon to control the downward movement of the cap relative to the base. The matching cams are in the form of spaced projections 32 which extend upwardly from the top of the rib and spaced recesses 33 in the bottomrof the. groove. When the cap is in. operating position, the projections 32 are. aligned withv the recesses 33 andthecap. may be depressed relative to the base a sufficient distance to operate the valve. he projections 32, and the recesses 33 are arranged so that when the cap is rotated away from its Operating. position, the projections 32 engage with the bottomof the groove and prevent the cap from being depressed. This prevents accidental discharge of the container by pressure exerted on the cap in any position except the operating position of the cap.

The valve spring acts on the cap through the valvestem and thevalve operating member and valve stem normally holds the cap in its raised positionrclative to the base. Qrdinarily, the cap will be rotated 180 from its operating position to what may be termed the closed or non-operating position. 7

An, indicator 34- extending upwardly from the base provides an index to the position of the cap. The indicator 34 also extends over and closes the outlet of the discharge passagewayZS when the cap is in locked position and prevents foreign matter from entering the discharge passageway.

In the event that the contents of the container'are to be discharged as a spray, a discharge nozzle 35 may be inserted in the outlet of the discharge passageway 25 illustrated in Fig. 7.

In the modified form of a dispenser and valve operating-mechanism embodying the invention shown in Figs. 8 through 12, a difierent type of valve is used to close the opening in the container.

As shown in Fig. 8, opening in the closure member 13' isclosed by a spider 36 of flexible material. The spider 36. has a solid center or hub 37 which is held in sealing engagement with, the inturned flange or lip 38 surrounding the opening in the closure member for the container. Thehub 37 is connected by arms 39 to an annular rim 40- with openings 41 being located between the arms through which the contents ofthe container may be discharged when the hub is forced. out of engagement with theflange 38. The outer rim 4410f the spider is confined in a shell 42 which is forced into a necked'portion 43 surrounding the opening in the'closure member so as hold the .hub in. engagementiwith .the flange 38 under tension. The lower end of the shell communicates with the-interior of the containerand a siphon tube 19 may be attached thereto. A valve of this type is more fully described and claimed in my copending application S. N. 315,052 filed October 16, 1952, entitled Valve Mechanism-and reference may be made thereto.

The dispenser and valve operating mechanism consists of a base 22' and a cap v23' rotatably mounted on the base.

A hollow stem 44 carried by the cap extends. through an opening 24' in the base into engagement with the hub of the spider. The stem 44 has a lip 45 intermediate its ends which engages and forms a seal with ashoulder 46 on the sides of the opening on the base. Aspout 47 extends from one side of the base and forms discharge passageway 47a in the base which communicates with the opening-24 therein. the container are discharged through the openingv 24' in the base and through the spout and the pressure of the contents being discharged is transmitted to the inside of the hollow stem and forces the ip 45 into engagement with the shoulder 45 and forms an effective seal between the cap and thebase at this point.

"The base 22 has anannular rib 30 which fits into a groove 31 in the bottom of the cap'2'3'. The opposing surfaces of rib and groove have proiections 32' and recesses-33',respectively, formed thereon for controlling the movement of 'thecap relative to the basein the manner previously described.

In this case whenthe contents of Briefly, the operation of a combined dispenser and valve operating mechanism embodying the present invention is as follows. When the cap is in its inoperative position the index member extends over the discharge outlet in the. cap and the matching cam surfaces on the cap and base are in engagement so.=as to prevent downward movement of the cap relative to, the base. To operate thevalve, thecap is rotated 18 to, itsoperating position where the projections on the-rib-on the base can enter into the recesses in the bottom of the groove on the cap. I

When the cap is in'its operating position, it may then be pressed down against the force of the valve spring (or the spider) to open the valve. Upon opening of. the valve, the contents of the container will be dischargedqby the pressure in the container through the openingin the base and the discharge passageway communicating there with. The pressure of the contents being .dischargedacts on the tubular member extending downwardlyfromthe cap and fitting into the openingin the base to, form a seal between the cap. and the basev to prevent leakage of the contents between the cap and the base.
