Application October 26, 1937, Serial No. 171,150
1 Claim.
The invention relates to covers or closures for metallic receptacles, for instance gas containers or liquefiers, and has for its object to provide a cover disposed within the chamber of the receptacle, and provided with means cooperating with means carried within the receptacle for holding the closure in closed position over a filling opening and forming a leakproof connection.
A further object is to provide the closure with members cooperating with spaced cam surfaces within the receptacle chamber whereby upon a partial rotation of the closure it will be seated against a gasket around the filling opening in the bottom of the receptacle.
A further object is to provide the closure on its under side with means for the reception of a tool for positioning the closure and for imparting a rotation thereto for the jamming operation.
A further object is to provide a receptacle closure within a receptacle and having a threaded connection in the filling opening for forming a tight closure upon rotation thereof.
With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed Without departing from the spirit of the invention.
In the drawing:
Figure 1 is a view in elevation of the receptacle.
Figure 2 is a vertical transverse sectional view through the bottom of the receptacle and 010- sure.
Figure 3 is a horizontal sectional view taken on line 3-3 of Figure 2.
Figure 4 is a detail perspective view of a portion of the receptacle, showing the cam flanges.
Figure 5 is a modified form of closure showing the same in vertical transverse section in the bottom of a receptacle.
Figure 6 is a horizontal sectional View taken on line 66 of Figure 5.
Figure 7 is a vertical transverse sectional view through the bottom of a receptacle, showing a further modified form of closure.
Figure 8 is a horizontal sectional view taken on line 88 of Figure '7.
Referring to the drawing and particularly to Figures 1 to 4 inclusive, the numeral l designates the receptacle in which gas or other fluid is to be received and stored and Z the chamber of the receptacle. they are refilled from time to'ti-me through a bottom filling opening 3 in the bottom 4 thereof, however it is desirable to place the closure 5 within the receptacle chamber so it will always be in the receptacle for ready use, and at the In receptacles of this character,
same time will not interfere with the cleaning or sterilizing of the receptacle chamber, which is one of the difliculties now experienced with liquid containers, for instance carbon dioxide liquefiers.
The closure 5 is provided with a central threaded opening 6 for the reception of a handling tool or bolt, and with a plurality of outwardly extending arms 1 around its periphery, formed integrally with the inner wall of the receptacle are interrupted cam members 8 concentrically arranged, and between the adjacent ends of which the arms 1 are received when the closure is placed over the opening 3 in engagement with the gasket 9. It will be noted that the under surfaces [0 of the members 8 extend concentrically and inclined downwardly, therefore it will be seen that when a partial rotation is imparted to the closure, it will be forced into close binding engagement with the gasket 9, thereby compressing the same and forming a leakproof connection. Closure 5 could be of the captive type if desired.
Referring to Figures 5 and 6, in this form the closure 5a is provided with a threaded extension II, which is threaded at It into the filling opening l3, otherwise the construction and operation is the same as set forth in Figure 2.
Referring to Figures 7 and 8, in this form the closure 5b is disposed within a counterbore I4 of the filling opening 3, against the gasket [5, and is threaded at I6 into the counterbore. It will be noted that both forms 5 and 6 are provided with double sealing means formed by the threaded connection It and the gasket I 5.
From the above it will be seen that a metallic receptacle closure is provided which is simple in construction, the parts reduced to a minimum and the cover will not depend on internal pressure for insuring a close fit. It will also be seen that access may be readily had to the interior of the receptacle for cleaning and sterilizing purposes, and all of the parts are disposed within the receptacle lines, thereby preventing damage thereto incident to handling, which is an important factor as the receptacles are usually heavy and roughly handled.
The invention having been set forth what is claimed as new and useful is:
The combination with a receptacle having a chamber and a filling opening in the bottom thereof, of a closure within the chamber for said opening, said closure having outwardly ex-
