CONTAINERHNALVE 7' Filed June 21, 1937 Patented June 1938 UNITED STATES PATENT. OFFICE CONTAINER VALVE Stephen D. Hal-tog, Normandy, M0. Application June 21,1937, Serial No. 149,353 Claims. (01. 221-60) tainer valves, more particularly, to valves adapted foruse on collapsible tubes.

The purpose and use of container valves, caps,

closures, and like devices employedto open and close the discharge aperture of tubes has been abundantly described in extant literature, and:

further reiteration therefore'would onlyz'be .ad-

10 ditional surplusagaexcept, to brieflysummarize;

quantity of material used in the make-up of the valve should be within scant limits.

v 5'.- The primary object, therefore, ofthe invention.

herein-described and illustrated, is'to provide a V container valve-designed and constructedin such, a novel, economical, and practical manner, that all of the difficulties and in'capacities encountered 1 Qhinprior art types of container valves are surmounted.

To such ends the'inventionherein described and'illustrated provides:

A'container valve having few parts in itsqconstruction.

A container valve closure having oscillator movement upon a pivot and bearing of novel construction.

A" container valve having a closure capable of being sustained, supportedly in any suitableposition within the sweep of its oscillatory movement.

A container valve having resiliently yieldable lock engaging means.

' A'container valve in which all of its parts are "so designed and constructed that theyare capable of j'production by means'of die-forming processes,

thus insuring economical production, accurate duplication, and indefinite reproduction.v

v For the purpose more clearly to understand the expressed objects, and other attending objectaof.

the container valve herein described and illustrated, the following description is' given, and by aid of the accompanying drawingv it is discerne 551113182 gThis' specification, aided by the accompanying, drawing, discloses certain improvements .in'con- Fig; 1 is a plan view of the container valve shown in mounted position upon a tube.

Fig. 6 is a plan view of a fabricated washer.

Fig. '7 is a cross-sectionalview thereof on line- The parts constituting the container valve are herein designated numerically and in the order of which l0 designates a portion of a container body denominated a collapsible tube. Formedon the apertured dischargeend of the tube Ill is an 20 apertured neck ll, having at the base thereof a ledge l2.on which there is a surface i3 providing a shoulder. Mounted on the apertured neck ll and having a bearing upon the surface 13, is that of a die-formed integrally unitary metallic slug 5 I4 having an aperture 15, the aperture l5 beingsized to fit snugly on the neck I I. Within the surfacesurrounding the aperture [5 there is a chamfer I6, and into which chamfer a rim of metal I! is spun to secure the slug I4 to theneck 30 of the tube. Within the body of'the slug |4,.a depression I8 is formed by punchinga portion 19 of the body of the slug'only part way through; thus, adepression is formed in one surface and a projectinggportion 20 is expressed-upon the op- 5 posite surface of the-slug. Extending laterally from the body'of the slug M are limbs-2i and 22 rectangular in form as and when punched'from flat metal, and designed 1 to provide bearings.

Within a face end surface midway the extremi- 40.,

ties of the projecting limbs 2| and 22, an in-; dentation 23 is formed. The discharge aperture 24 of the tube isprovided with a closure 25, hav-- ing projecting portions26 and 2'l, Which portions are bent to form journal bearings adapted to em- .45 brace the limbs 2| and 22 0f the slug, and upon Which journal bearings the closure 25 has oscillatory movement. The closure 25 is also provided witha projecting tang 28, formed to engage the indentation 23 andto contact spring tensionally 50.

therein, whereby the closure is not only prevented from having lateral movement on its bearings, but the closure is alsocapable of being sustained supporte dly in any suitable position in which it ma b lewrs w tlainrh sw of its o i a o y,

movement. In order to maintain the closure in its aperture-closing position on the tube, a resiliently yielding locking means is provided by forming angularly bent portions 29 and 30 and in which portions a tab of metal 3! is formed to provide a latch adapted to engage the surface 32 of the slug M. In order to provide the requisite spring tensional resiliency for the closure locking means, an opening 33, aided by cut-out-notches 34 and 35, is formed in the cover or closure, and between which opening there are stay portions 36 and 37 having a yieldingly resilient spring tensional capacity. The width and length of the stay portions can be properly proportioned to accommodate any desirable resiliency. To prevent leakage of the valve a fabricated disc 38 apertured and having a yieldable compressive capacity is employed. The fabricated disc is positioned within the depression E8 of the slug, and in which position serves to prevent leakage by forming a seal with the cover, due to its yieldability under contact pressure of the closure, when the closure is pressed to a locked engagement with the slug.

The opening of the closure is brought about by finger pressure exerted against the under surface 39 of the bent projection 30.

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 is susceptible of modification in its form, proportions, detailed construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

While the invention has been described in language more or less specific as to structural features, it is to be understood 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.
