This invention .relates to the Icontrol of iuids escaping from eontainers. It is esnecaily l'concerned with preventing the passage into the atmosphere of noxious lgasesleall-lng from containes in which they are stored.` As' a speciiic exampie of the utility of the invention, it may be neted that the sto'i'age of lchlorine .under pressure has long presented a problem owing to the disastrous consequences likely to arise inthe event koffleakjage of the gas into the 'presence of human beings.

The flexible membrane I3 now engages the container I0 in a Zone of substantial width, extending around the container, and with an especially tight and leakproof fit. Any gas leaking through the cap I I, or from any part of the container I above the membrane I3 is thus imprisoned within the cap I2. Through the engagement of the yoke piece I9 with the bottom of the container III, the cap I2 is prevented from receding from the position to which it has been placed, and the seal between the membrane I3 and the container I0 is maintained with undiminished tightness.
So tight is this seal in practice that I have found it necessary to devise special means for removing the cap from the container. For that purpose, I provide a pair of shoes 22, l2 (Figs. 5 and 6) each comprising a semi-cylindrical piece of sheet metal rigidly attached, as by brazing, to a curved bar 23 of rectangular cross-section. This bar serves both as a support for the sheet metal portion of the shoe and also to provide a shoulder against which to drive the sheet metal portion between the flexible membrane I3 and the wall of the container III. The sheet metal section of the shoe is crimped, as illustrated at 22 to facilitate entry of the shoe between the membrane and the container wall.
It will be noted that the opening in the annular plate I5 is of such diameter as to provide suflcient space for the entry of the shoes 22 between said plate and the container wall. When the shoes are driven upwardly between the membrane I3 and the container IB, as illustrated in Figs. 5 and 6, they break the adhesive seal between said membrane and container; so that the cap I2 may now be removed by rst drawing the yoke to the left (Fig. 2), disengaging the yoke plate I9 from the container, and then pushing the yoke and cap upwardly.
In Figs. 'l and 8, I have illustrated alternative arrangements for obtaining a pressure-tight seal between the cap I2 and the flexible membrane I3. As shown in Fig. '7, the lower end portion of the cap I2 may be flared outwardly at I2 and then extended inwardly to provide a flange I2 for receiving the membrane I3. The latter may be clamped between said flange I2 and an annular plate 25 by screws 26.
In Fig. 8 the lower end portion of the cap is bent outwardly to form a ange 21; and the membrane I3 is clamped between said ange and an annular bar 28 of angular crosssection, through screws 29.
The cap I2 may be provided with a suitable valve, as indicated at 30, for relieving pressure Within the cap when desired. The valve 30 should, 'of course, be open during the applying of the cap to the container. Said valve may be of well-known construction, comprising a body member 3| having screw threaded engagement in the valve casing and normally obstructing passage to the outlet 32. The body member 3l has a stem 3l extending outside the valve casing for operation by a suitable wrench.
It will be seen that my invention provides a safety-device of simple construction for effectively preventing the escape of noxious gases from the container to the atmosphere. The device may be quickly applied to the container by one attendant without tools and, when applied, is maintained in tightly sealed condition through the engagement of the flexible membrance I3 with one end portion of the container and the yoke plate I9 with the opposite end. When removal of the cap I2 is desired, the shoes 22 provide a simple and effective means whereby the gas-tight seal between the membrane I3 and container I0 may be broken. It will be apparent that, while I have illustrated the cap I2 as applied to the upper end of the container, said cap may instead, if desired, be applied to the lower end, in which event the yoke plate I9 is engaged with the container cap II. The cap I2 may be readily applied to either end of the container I0 whether the latter be in horizontal, vertical, or other position. The device may further be applied to either end of a container not equipped with shipping cap II, and also when the container valve (not shown) is fitted with the customary auxiliary valve or connected piping to the users processes, if such connecting piping be severed or confined to an area which may be encased within cap I2.
The terms and expressions which I have employed are used as terms of description and not of limitation, and I have no intention, in the use of such terms and expressions, of excluding any equivalents of the features shown and described or portions thereof, but recognize that various modifications are possible within the scope of the invention claimed.
I claim:
1. Apparatus for confining uids escaping from a container, said apparatus comprising a cap having a flexible membrane sealed thereto and extending inwardly of said cap, said membrane having an opening therein of substantially less area than the cross-sectional area of said container whereby said membrane surrounds the container and adherently engages the same over a substantial zone on the container body when the cap is applied, a yoke comprising a pair of arms connected with said cap, a plate extending between the ends of said arms opposite said cap, said arms being of such length that when said cap is pushed over an end of said container said plate is adjacent the other end of the container in position for being pushed into engagement with said other end.
