. This specification, aided by the accompanying drawin d scl se e i w an useful mprovements in features of construction as well as the means and mode of operation of container valves of the character relating to container valves in which the valve aperture closure is engaged permanently to the valve for continuous operative employment thereon thereby serving to eliminate the objectionable performance of screwing the aperture closure on and off the container.

The primary object therefore of the herein described and illustrated invention is to simplify the construction of container valves in a novel, economical and operative efiicient manner whereby all of the diiiiculties and incapacities encounteredin prior art structures are overcome.

To such ends, briefly summarized, this inven-, tion is, as, in and for a container valve characterized by features providing.--

A container valve simple in construction and perat on- A container valve having iew parts and there fore of minimum production cost.

A container valve designed and constructed for production by means of die-forming processes.

. A container valve in which the discharge aperture of the valve is opened and closed by means of a rotatory member adapted to impart a per pendicular movement to a resiliently yieldable spring tension aperture opening and closing member of the valve.

A container valve in which the rotatory member effects an opening of the valve when moved in one direction and when the rotatory member 35. is turned in an opposite direction, the aperture closure member tensionally springs into an aperture closing positi n- For the purpose more clearly to understand the expressed objects, and other attending objects, the following description is given, and by aid of the accompanying drawing, it is discernable:

The member parts constituting the structure of this container valve are designated up n the drawing in numerical order, whereby l5 identifies a fragmentary portion of a container provided with an apertured discharge end it, which dis charge end is surrounded by an embossment ll having a projecting lug ll..a. Mounted upon the discharge end of the container I5 is a circularly formed body or collar IS, the collar I8 being pro-. vided with an apertured circumvolving curved rim l9 having extending funnel shaped walls 23 terminating in a rim 2| provided with integrally formed projecting tabs 22. At a suitable position within the core of the body, or collar l8, an embossment 23 is provided and constituting a re-, taining lug, and within the end face surface of the curved rim I9, a notch 24 is formed provid ing a key-way.

In assembly with the collar I8 is a disc shaped cover or cap 25 having an aperture 25, a depending rim 21, a series of perforated slots 28, and an embossed projection 29. There is included in the assembly with the body or collar N3, the cover or cap 25, a perforatedwafer-plate or diaphragm 30 having a central portion 3| provided with a circularly formed embossment 32, a teat 33 and a circumferentially located indentation providing a key-way 34. The assembly also includes a yieldable fabricated gasket 35. The gasket 35 is provided with a leaf-like form 36 having an aperture 31.

As a unitary container valve assembly, the several member parts are arranged together in assembled relation upon the discharge end of a container by way of placing the cored body, or collar l8, upon the container in a way to permit the open rim end IQ of the collar to surround the embossrnent ll; arranging the key-way 24 in a manner to embrace the lug l'l-a, and then beading or otherwise spinning the marginal end of the embossment I! in a manner to overlap within the curved rim portion 19.

Having thus arranged the circularly formed body or collar H! to the container, the wafer-plate or diaphragm is then placed within the rim 2| of the collar l8, and upon the flat surface of the v Wafer-plate 38, the yieldable fabricated gasket is placed. The cover or cap 25 is then mountedly positioned on the collar l8 in a way to permit the projecting tabs 22, of the collar l8, to enter into the elongated apertures 28 of the cap 25 with the embossed projection of the leaf-like spring portion of the disc 30 entered into the discharge aperture 26 of the cap 25.

The cap 25 is then subjected to a compressive force sufficient to compress the fabricated gasket 35 in a manner to provide a seal-tight joint between the surfaces with which the gasket 35 is in contact; the projecting tabs 22 are then bent in a way to bear upon the surface of the cap 25, and yet not to bind the cap too tightly upon the members with which it is associated in assembly.

Thus arranged the valve is in condition for operation. The valve is opened by way of turning or rotating the cap 25 in the direction indicated in the drawing by arrow GFig. 1, until the edge surface 38 of the elongated slots 28 contact with the side wall surfaces 39 of the projecting tabs 22, whereby the embossed projection 29 of the cap 25 rides upon the teat 33 of the wafer spring formation 3|, causing a deflection of the wafer spring 3! and thereby withdrawing the embossed projection 22 out of the cap aperture 26 thereby opening the valve, Thus opened, the valve is capable of discharging its contents through the discharge aperture 26 of the cap 25.

The closing of the valve aperture 26 is effected by rotating the cap 25 indicated in the direction by arrow G Fig. 1 until the edge surfaces 40 of the elongated slots 28 contact with the side wall surfaces 4| of the tabs 22 thereby causing the embossment 29 .to ride off the teat 33 in consequence of which the aperture sealing embossment 32 of the wafer spring portion 3| springs tensionally back into the discharge aperture 26, thus closing the discharge aperture of the valve.

' The description discloses that by rotating the valve cap 25 in a horizontally right-hand and left-hand direction, a perpendicular movement is imparted to the resiliently yieldable portion of the wafer-plate aperture opening and closing portion of the valve.

Having thus described the invention, it is obvious that there is provided a container valve of the character described and possessed of the advantageous features hereinbefore enumerated as desirable. It is therefore to be understood that the container valve issusceptible of modification in its form, proportions, detailed construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

The invention, having been described in language more or less specific as to structural features, it is to be understood, however, that the invention is not limited to the specific details shown, but that the means and construction herein disclosed comprises the preferred form of several modes of putting the invention into effect and the invention therefore is claimed in any of its forms or modifications within the legitimate and valid scope of the appended claims.
