This invention is related to a closure connected to a coupler. Particularly, this invention is related to a closure and a coupler used in a dispensing valve assembly.
BACKGROUND OF THE INVENTIONDispensing valves are widely used in the foodstuffs industry, such as for dispensing condiments including for example, ketchups and mustards, or for dispensing other fluid like foods such as milk, or the like. Typically, a conventional coupling valve includes a first end and a second end to define a flow passage therethrough. The first end is connected to a fluid dispensing system, and the second end is used for fluid dispensing. By controlling a handle or lever of the coupling valve, the coupling valve is actuatable between an open configuration to allow fluid flow and a closed configuration to prevent fluid flow.
However, since the conventional coupling valves may include many parts made separately by using different materials, it is difficult to reduce the cost. Further, some conventional coupling valves experience leaking problems when the valves are in the closed position. Moreover, most dispensing valves only have dispensing function while lacking fill through capabilities. Therefore, there is a need to provide a dispensing system and coupling valve that will prevent leaking problems when the valve is intended to be in the closed position, such as during transport or other instances when not in use. In addition, there is a need to provide a dispensing valve that also can be used for filling a fluid source.

When the closure 50 is connected with the coupler 80, the closure valve handle 58 interlocks with an internal space 90 of the coupler valve handle 91, as shown in
A receiving area 210, which may be an activating ramp, may be located at a second end 212 of the closure body 254. The receiving area 254 engages a locking member of a coupler, thereby releasing the locking member and allowing the coupler and the closure, which are connected, to be rotated into an open position. The second end 212 of the closure body 254 also includes a neck portion 242 which may be a flange or a weld flange. The second end 212 also includes a stop 230 such that the stop 230 facilitates proper rotation when a coupler is attached. The interlock 232 prevents a coupler and the closure from pulling apart when in an open configuration.
As illustrated in
In
The housing 282 also includes a lock retainer 296 that retains a locking member 500. The locking member 500 prevents rotation of the coupler 280, when the coupler 280 is not connected to a closure, from being rotated out of a closed configuration. The locking member 500 may be released to allow opening of the coupler 280 when the coupler 280 is attached to the closure such as closure 250. Similarly, the locking member 500 may lock the coupler 280 to prevent opening of the coupler 280 when the coupler 280 is not attached to the closure 250. Particularly, the locking member 500 prevents the coupler valve 284 from rotating relative to the housing 282 into the open position. Further, the locking member 500 locks the coupler in its uncoupled state 280 and ensures proper orientation is preserved between the coupler 280 and the closure 250 in their closed positions. Locking the coupler 280 in the closed position prevents air from being introduced into the dispensing system and fluid from draining from a line going to the coupling. The locking member 500 may be, but is not limited to, a pivot lock. The locking member 500 includes a protrusion 505 that may contact a receiving area (such as 210 above) of a closure. In the coupled state, the protrusion 505 contacts the receiving area of the closure to release the locking member from blocking the stops of the coupler valve. As above, the receiving area 210 may be an activating ramp. The locking member 500 may be controlled with a spring 506 for biasing the locking member into locked and release configurations. The spring 506 may be but is not limited to a latch or leaf spring. The opening 298 may include an extended tubular portion 297 that may be barbed.
The coupler valve 284 includes a first end 285a and a second end 285b. The second end 285 may include an O-ring for providing a fluid tight seal when connected with a closure. Stops 281 have been described above, and may also communicate with a stop on a closure to provide proper rotation between the coupler valve and the closure body. The stops also include an interlock portion 281a such that the coupler 280 may be connected with a closure (such as 250) thereby preventing the coupler 280 and a closure from pulling apart when in an open configuration.
The first end 285a includes at least one protrusion 286 that may have lock snaps 289. The protrusion 286 may be inserted into an internal space 402 of the handle 400. The lock snaps 289 secure connection with the handle 400. The handle 400 may be rotated thereby rotating the coupler valve 284 to actuate the coupler to an open configuration or a closed configuration. The protrusion 286 may contain its own internal space such that a handle from a closure may be inserted into the internal space of the protrusion 286 to interlock the handle 400 with a closure handle (such as 261). When the handle 400 is rotated, the handle 400 may simultaneously actuate a coupler and a closure to an open or a closed configuration. The handle when rotated in a closed position may shut a fluid dispensing assembly off to vacuum.
The handle 400 may be connected to a shroud 300 that surrounds the coupler 280 and the closure 250. The shroud may be provided with a ramp 303 to allow entry of the locking member 500, and also a groove 305 to allow the opening 298 to fit through. A biasing member 506 such as a leaf spring provides biasing for the locking member 500 to bias the locking member 500 in a normally locked configuration. When the locking member 500 is released by a receiving area 210 of the closure 250, the fluid dispensing assembly including the coupler 280 and the closure 250 may actuate into an open configuration.
As shown in
As discussed above, the present invention offers many advantages. For instance, interlock features of the closure and the coupler allow for a secure connection of the fluid dispensing assembly preventing the closure and the coupler from pulling apart when in an open configuration. Also, the locking member feature provides an anti-rotation interlock so as to prevent the coupler from being rotated out of a closed configuration when not connected to a closure. Furthermore, the locking member may be released to allow opening of the coupler when the coupler is attached to the closure. Also, the locking member locks the coupler in its uncoupled state and ensures proper orientation is preserved between the coupler and the closure in their closed positions. Locking the coupler in the closed position prevents air from being introduced into the dispensing system and fluid from draining from a line going to the coupling. The in-line orientation of the closure and that the closure may be a part of the fluid source allows for the ability to fill the fluid source through the closure.
The foregoing descriptions of the preferred embodiments of the invention have been presented for the purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in light of the above teachings.
