Patented Sept. 30, 1947 PRESSURE RELIEF STOPPER FOR CONTAINERS Gustave A. Hall, Racine, Wis.

1 Claim. 1
My invention refers to stoppers for containers wherein the contents will develop pressure, the same being particularly applicable to Thermos bottles or the like.
The primary object of my invention is to pro vide a simple, durable and low cost stopper so constructed and arranged as to relieve pressure above a predetermined point.
The specific object of my invention is t provide a cork stopper having a vent channel therethrough, closed by a top button and a bottom disk, the same having a, bleed opening therein communicating with the vent channel, controlled by a coil spring passing through the vent channel and connecting the disk and top button.
With the above and other minor objects in view, my invention consists in certain peculiarities of construction and combination of parts as will be fully set forth hereinafter with reference to the accompanying drawings and subsequently claimed,
In the drawings:
Figure 1 represents a sectional elevation through a stopper embodying the features of my invention. And
Figure 2 a top plan view of the same with a portion broken away to more clearly illustrate structural features.
Referring by characters to the drawings, l indicates a stopper body preferably composed of cork although other substances may be substituted therefor.
The stopper has a central vent channel 2 extending therethrough. Fitted to the discharge mouth of the channel and resting upon the top surface of the stopper is a button 3 having a gripping shank 3' extending upwardly therefrom, and the bottom surface of the button is provided with an apertured ear 4.
The bottom surface of the stopper has centrally fitted thereto a disk 5, which disk closes the intake mouth of the vent channel, and the central portion of said disk has extending into the channel an apertured ear 6. The disk is also provided with a bleed opening 5' extending therethrough and communicating with the vent channel.
The top button and bottom disk are held in position by a tension coil spring I, the ends of which spring are connected to the apertured ears of the button and disk, as shown, whereby said parts are securely held over the intake and discharge mouth of the cork or stopper channel.
From the foregoing description of the cork assemblage, it will be noted, when said cork is securely fitted to the mouth of a container, it will, under normal conditions, positively serve as a non-leak stopper.
In the event the contents of the bottle develop an abnormal gas pressure, the vapor will slowly leak through the bleed in the disk and fill the channel, whereby the button, under spring tension, will yield slightly and permit escape of the vapor.
When it is desired to remove the stopper, the operator grasps the shank of the button and in lifting thereon will fully relieve the Pressure and at the same time the cork or stopper may then be readily removed.
While I have shown and described one simple exemplification of my invention, it is understood that I may vary the structural features of the same within the scope of the claim.
I claim:
A pressure relief closure for containers comprising a stopper having a vent channel extending therethrough forming a top discharge mouth and a bottom intake mouth, a button closure for the top discharge mouth, a shank extending from the top of the button closure, an ear extending from the bottom of the button closure within the vent channel, a closure disc engaging the bottom intake mouth of the stopper, the closure disc having a vent bleed extending therethrough communicating with the vent channel, an ear extending from the inner surface of the closure disc Within the channel, and a tension coil spring connecting the ears of said closure disc and button closure and holding the closure disc against the bottom of the stopper and the button closure against the top of the stopper.
GUSTAVE A. HALL.
