Abstract

A closure and valve for liquid containers comprises a valve body and a plug body insertable and rotatable therein. Discs are seated within the valve body which have off-center holes which are aligned or misaligned by stems depending from the bottom edge of the plug and which register with notches in the edges of the disc. A non-rotating disc having corresponding off-center holes is placed between the rotating discs. The valve is opened and closed by rotating the plug, after placement in the valve body, which rotates the rotatable discs with respect to the fixed disc.

Claims

1. A closure, filling and dispensing device for drums and other containers for liquids comprising

(a) a lower valve body consisting of a cylindrical housing with an inner wall,

(b) a rotatable upper plug body insertable into valve body (a) and having two channels therein and equipped with liquid and gas supply lines traversing the top of the plug body,

(c) a groove in the inside wall of valve body (a) or in the outside wall of plug body (b),

(d) a guide detent protruding from the inside wall of valve body (a) or from the outside wall of plug body (b) positioned to register with and pass through the groove (c) when the valve and plug bodies are assembled, to lock them together,

(e) two rotatable in-line discs positioned in said valve body, said discs having off-center fluid inlet and outlet openings and an axial hole, said plug body having at least one downwardly depending stem for rotating said in-line discs,

(f) a non-rotating disc, positioned in said valve body between said rotating discs, having an axial hole and off-center fluid inlet and outlet openings which will register with corresponding openings in the discs of (e),

(g) an axial splined shaft secured in the bottom of the valve body which non-engagedly traverses the axial holes in the rotating discs but engages the wall of the hole in the non-rotating disc,

(h) the rotating discs being notched on their edges to receive said depending stem to rotate the rotating discs but not the non-rotating disc when the plug body is rotated,

(i) the holes in the rotating discs always being in alignment with respect to each other and in alignment with the holes in the non-rotating disc during fluid transfer but in non-alignment therewith when the valve is closed during storage or transit of the drum,

(j) fluid inlet and outlet channels in the valve body (a) corresponding to and aligned with the channels in the plug body (b).

(k) and means for holding the valve body and plug body together after assembly.

3. A device according to claims 1 or 2 wherein the detent protrudes from the inside wall of the valve body (a) and the groove (c) is in the outside wall of the plug body (b).

4. A device according to claims 1 or 2 wherein the detent protrudes from the outside wall of the plug body (b) and the groove (c) is in the inside wall of the valve body (a).

5. A device according to claim 1 wherein the rotating disc positioned below the non-rotating disc has a short vertical wall notched to receive said depending stem.

6. A device according to claim 1 wherein the groove (c) in the wall of the valve body (a) which accepts the detent (d) of the plug body (b) has a short vertical leg and a longer horizontal leg.

7. A device according to claim 5 wherein the rotating disc positioned above the non-rotating disc has a shoulder, the under surface of which registers with and overlays the upper surface of the short vertical wall of the lower rotating disc.

8. A device according to claim 1 wherein the plug body (b) has two depending stems positioned about 180°

from each other.

2. A closure, filling and dispensing device for drums and other containers for liquids comprising

(a) a lower valve body consisting of a cylindrical housing with an inner wall,

(b) a rotatable upper plug body insertable into valve body (a) and having two channels therein and equipped with liquid and gas supply lines traversing the top of the plug body,

(c) a groove in the inside wall of valve body (a) or in the outside wall of plug body (b),

(d) a guide detent protruding from the inside wall of valve body (a) or from the outside wall of plug body (b) positioned to register with and pass through the groove (c) when the valve and plug bodies are assembled, to lock them together,

(e) two rotatable in-line discs positioned in said valve body, said discs having off-center fluid inlet and outlet openings and an axial hole, said plug body having at least one downwardly depending stem for rotating said in-line discs,

(f) a non-rotating disc, positioned in said valve body between said rotating discs, having an axial hole and off-center fluid inlet and outlet openings which will register with corresponding openings in the discs of (e),

(g) an axial splined shaft secured in the bottom of the valve body which non-engagedly traverses the axial holes in the rotating discs but firmly engages the wall of the hole in the non-rotating disc,

(h) the rotating discs being notched on their edges to receive said depending stem to rotate the rotating discs but not the non-rotating disc when the plug body is rotated,

(i) the holes in the rotating discs always being in alignment with respect to each other and in alignment with the holes in the non-rotating disc during fluid transfer but in non-alignment therewith when the valve is closed during storage or transit of the drum,

(j) fluid inlet and outlet channels in the valve body (a) corresponding to and aligned with the channels in the plug body (b),

(k) and means for holding the valve body and plug body together after assembly.
