Abstract
A valve for a liquid dispensing container includes a body adapted to mount on a liquid container. The body has a cavity with a peripheral sidewall and a flexible resilient bottom diaphragm. A liquid inlet is provided through the sidewall of the body. A valve member is provided having a first end, a second end, and a peripheral sidewall. An outlet extends through the sidewall adjacent the first end.
A flow passage extends through the valve member from the second end to the outlet. The valve member seals the cavity and is reciprocally movable in the cavity between a first retracted position and an extended position. In the first retracted position, the outlet of the valve member is blocked by the sidewall of the body. In the extended position, the outlet of the valve member protrudes out of the cavity, thereby allowing liquid to flow from the inlet along the flow passage to the outlet. The valve member is coupled to the bottom diaphragm. The bottom diaphragm biases the valve member into the first retracted position. The valve member is moved from the first retracted position to the extended position to permit liquid to flow.
A flow passage extends through the valve member from the second end to the outlet.

Description
TIT7~E OF THE INVENTION
A valve for a liquid dispensing container and a liquid dispensing container equipped with the valve FIE?~D OF THE INVENTION
The present invention relates to a valve for a liquid dispensing container and a liquid dispensing container equipped with the valve.
g,ACKGROUND OF THE INVENTION
In order to dispense liquid from a container, one must either pour the liquid from the container or equip the container with a valve through which liquid may be selectively dispensed.
St11~1RY OF THE INVENTION
What is required is valve for use in dispensing liquid from a container.
According to one aspect of the present invention there is provided a valve for a liquid dispensing container which includes a body adapted to mount on a liquid container. The body has a cavity with a peripheral sidewall and a flexible resilient bottom diaphragm. A liquid inlet is provided through the sidewall of the body. A valve member is provided having a first end, a second end, and a peripheral sidewall.
An outlet extends through the sidewall adjacent the first end. A flow passage extends through the valve member from the second end to the outlet. The valve member seals the cavity and is reciprocally movable in the cavity between a first retracted position and an extended position. In the first retracted position, the outlet of the valve member is blocked by the sidewall of the body. In the extended position, the outlet of the valve member protrudes out of the cavity, thereby allowing liquid to flow from the inlet along the flow passage to the outlet. The valve member is coupled to the bottom diaphragm. The bottom diaphragm biases the valve member into the first retracted position. Means is provided for selectively moving i.he valve member from the first retracted position to the extended position.
The valve, as described above, is suited for use with a liquid dispensing container. Liquid is dispensed through the valve when the valve member is moved from the first retracted position to the extended position.
Although beneficial results may be obtained through the use of a valve, as described above, there are improvements which may be added to enhance the operation of the valve.
In order to allow manual dispensing, it is preferred that the valve member have a gripping portion. This enables the valve member to be gripped and a force exerted to overcome the biasing of the bottom diaphragm to manually move the valve member from the first retracted position to the extended position.
In order to allow for dispensing from a dispensing machine, it is preferred that a second retracted position be provided for the valve member. In the second retracted position the valve member is pushed into the cavity deforming the bottom diaphragm until the first end of the valve member clears the inlet. This allows liquid to flow directly from the inlet bypassing the flow passage and the outlet.
Although the valve member may be moved manually to the second retracted position, it is envisaged that this will be done through a pin style of valve coupling as will hereinafter be further described and illustrated.

According to another aspect of the present invention there is a liquid dispensing container which includes a cardboard box containing a polymer plastic dispensing bag. A
dispensing valve, as described above, is provided having a body mounted on the cardboard box in liquid communication with the bag.
Although beneficial results may be obtained through the use of the liquid dispensing container, as described above, there are further features which may be added to enhance operation.
It is envisaged that the valve body will be mounted to one of the closure flaps on the cardboard box. This, however, raises an issue of stability of the closure flap when a force is exerted upon the valve member either manually or by a pin style coupling of a dispensing machine. Even more beneficial results may, therefore, be obtained when the cardboard box has an underlying closure flap and an overlying closure flap. The overlying closure flap has a slotted opening. The underlying closure flap has deformable tabs which extend through the slotted opening and are bent over to stabilize the overlying closure flap by securing the overlying closure flap to the underlying closure flap.
It is convenient if the use can, at a glance, readily determine the level of liquid in the liquid dispensing container. Even more beneficial results may, therefore, be obtained when the cardboard box has a peripheral sidewall with slotted openings which permit the liquid level within the bag to be viewed.

A preferred embodiment of valve for a liquid dispensing container generally identified by reference numeral 10, will now be described with reference to gIG~S 1 through 5_ A
preferred embodiment of liquid dispensing container generally 5 identified by reference numeral 100, will now be described with reference to FTGURES 6 through g.
Structure and Relationship of Parts of valve 10:
Referring to FIGURE 1. there is provided a valve 10 for a liquid dispensing container, which includes a body 12.
Referring to FIGUgg 2, body 12 has a cavity 16 with a peripheral sidewall 18 and a flexible resilient bottom diaphragm 20. A liquid inlet 22 is provided through sidewall 18 of the body 12. A valve member 24 is provided that has a first end 26, a second end 28, and a peripheral sidewall 30.
Valve member 24 is connected to diaphragm 20 by a connecting member 25 which extends through a centrally positioned opening 27 in diaphragm 20. Connecting member 25 has bulbous head 29 which prevents connecting member 25 from sliding back through opening 27 in diaphragm 20.
An outlet 32 extends through sidewall 30 adjacent first end 26. A flow passage 34 extends through valve member 24 from second end 28 to outlet 32. Valve member 24 seals cavity 16 and is reciprocally movable in cavity 16 between a first retracted position illustrated in GIGO 2, a second retracted position illustrated in FIGS 5 and an extended position illustrated in GIGO 3. Referring to FIGS 2, in the first retracted position, outlet 32 of valve member 24 is blocked by sidewall 18 of body 12. Referring to FIGS ~, in the extended position, outlet 32 of valve member 24 protrudes out of cavity 16, thereby allowing liquid to flow from inlet 22 along flow passage 34 to outlet 32. Arrows 36 indicated the path of liquid. Referring i~o FIGS 5, in the second retracted position, valve member 24 is pushed into cavity 16 deforming bottom diaphragm 20 until first end 26 of valve member 24 clears inlet 22, thereby allowing liquid to flow directly from inlet 22 bypassing flow passage 34 and outlet 32. Arrows 36 indicated the path of liquid. Valve member 24 is coupled to bottom diaphragm 20. Bottom diaphragm 20 biases valve member 24 into first retracted position. Valve member 24 has a recessed gripping portion 38, whereby valve member 24 is gripped and a force exerted to overcome the biasing of bottom diaphragm 20 and manually move valve member 24 to one of the extended position or the second retracted position.
Referring to Fz~ 4, although valve member 24 illustrated in gI~ 3, may be moved manually to the second retracted position, a dispensing pin 40 is provided to which force can be applied which to move valve member 24.
Dispensing pin 40 is adapted to engage with body 12 of liquid dispensing valve 10. Referring to FI~ 5, dispensing pin 40 has an internal flow conduit 42 and a first end 44 with external threads 46. A coupling 48 with interior threads 50 is inserted into cavity 16 of body 12 and held within body 12 by friction fit. Dispensing pin 40 is engaged with coupling 48 by threading exterior threads 46 at first end 44 of 2'. dispensing pin 40 with interior threads 50 of coupling 48.
Coupling 48 has a plurality of openings 52 which permit liquid to pass from inlet 22 into flow conduit 42 of dispensing pin 40. Pin valve 50 has a threaded second end 54 that is adapted to be secured to a dispensing machine (not shown) .
Operation of valve 10:
The use and operation of valve for a liquid dispensing valve generally identified by reference numeral 10, will now be described with reference to F=G~S 1 through 5. Valve member 24 is reciprocally movable in cavity 16 between a first retracted position, illustrated in FIGUgg 2, a second retracted position illustrated in FIGURE 5 and an extended position illustrated in FIGS 3. Referring to FIGURE 2. in the first retracted position, outlet 32 of valve member 24 is blocked by sidewall 18 of body 7_2 such that no liquid enters flow path 34. Bottom diaphragm 20 serves to bias valve member 24 into the first retracted position. Referring to FIGURE
g, when liquid is required valve member 24 is gripped by recessed gripping portion 38, and a force exerted to overcome the biasing of bottom diaphragm 20 and manually move valve member 24 to one of extended position.
In the extended position, outlet 32 of valve member 24 protrudes out of cavity 16, thereby allowing liquid to flow from inlet 22 along flow passage 34 to outlet 32. Arrows 36 indicate the path of liquid. Referring to FIGURE 5. when used with a dispensing machine, pin valve 40 can be secured to coupling 48 which is inserted into body 12 of liquid dispensing valve 10. A force can be applied to pin valve 40 to move valve member 24 to the second retracted position. In the second retracted position, valve member 24 is pushed into cavity 16 thereby deforming bottom diaphragm 20 until first end 26 of valve member 24 clears inlet 22, so as to allow liquid to flow directly from inlet 22 bypassing flow passage 34 and outlet 32 and into flow conduit 42 of pin valve 40.
Arrows 36 indicate the path of liquid.
Structure and Relationship of Parts of liquid dispensing container 100:
Referring to FIGS ~, there is provided a liquid dispensing container 100 which includes a cardboard box 112 with a polymer plastic bag 114. Referring to FIGS 6, cardboard box 112 has a peripheral sidewall 116 with slotted openings 118 thereby permitting a liquid level within bag 114 illustrated in FIGS ~ to be viewed. Referring to GIGO
cardboard box 112 has closure flaps 120 including an underlying closure flap 122 and overlying closure flaps 124.
One of overlying closure flaps 124 has a slotted opening 126.
Underlying closure flap 122 has deformable tabs 128 which extend through slotted opening 126 as illustrated in FIGURE
and are bent over as illustrated .in FZG~ 6, to stabilize overlying closure flap 124 by securing overlying closure flap 124 to underlying closure flap 122. Referring to FIGS g, dispensing valve 10 as described above is mounted to one of overlying closure flap 124 on cardboard box 112. Referring to GIGO ~, dispensing valve 10 is in liquid communication with bag 114. Referring to GIGO 6, slotted handles 130 are provided in peripheral sidewall 116 of cardboard box 112 to facilitate carrying dispensing container 100.

Structure and Relationship of Parts of valve 10:
Referring to FIGURE 1. there is provided a valve 10 for a liquid dispensing container, which includes a body 12.
Referring to FIGUgg 2, body 12 has a cavity 16 with a peripheral sidewall 18 and a flexible resilient bottom diaphragm 20. A liquid inlet 22 is provided through sidewall 18 of the body 12. A valve member 24 is provided that has a first end 26, a second end 28, and a peripheral sidewall 30.
Valve member 24 is connected to diaphragm 20 by a connecting member 25 which extends through a centrally positioned opening 27 in diaphragm 20. Connecting member 25 has bulbous head 29 which prevents connecting member 25 from sliding back through opening 27 in diaphragm 20.
An outlet 32 extends through sidewall 30 adjacent first end 26. A flow passage 34 extends through valve member 24 from second end 28 to outlet 32. Valve member 24 seals cavity 16 and is reciprocally movable in cavity 16 between a first retracted position illustrated in GIGO 2, a second retracted position illustrated in FIGS 5 and an extended position illustrated in GIGO 3. Referring to FIGS 2, in the first retracted position, outlet 32 of valve member 24 is blocked by sidewall 18 of body 12. Referring to FIGS ~, in the extended position, outlet 32 of valve member 24 protrudes out of cavity 16, thereby allowing liquid to flow from inlet 22 along flow passage 34 to outlet 32. Arrows 36 indicated the path of liquid. Referring i~o FIGS 5, in the second retracted position, valve member 24 is pushed into cavity 16 deforming bottom diaphragm 20 until first end 26 of valve member 24 clears inlet 22, thereby allowing liquid to flow directly from inlet 22 bypassing flow passage 34 and outlet 32. Arrows 36 indicated the path of liquid. Valve member 24 is coupled to bottom diaphragm 20. Bottom diaphragm 20 biases valve member 24 into first retracted position. Valve member 24 has a recessed gripping portion 38, whereby valve member 24 is gripped and a force exerted to overcome the biasing of bottom diaphragm 20 and manually move valve member 24 to one of the extended position or the second retracted position.
Referring to Fz~ 4, although valve member 24 illustrated in gI~ 3, may be moved manually to the second retracted position, a dispensing pin 40 is provided to which force can be applied which to move valve member 24.
Dispensing pin 40 is adapted to engage with body 12 of liquid dispensing valve 10. Referring to FI~ 5, dispensing pin 40 has an internal flow conduit 42 and a first end 44 with external threads 46. A coupling 48 with interior threads 50 is inserted into cavity 16 of body 12 and held within body 12 by friction fit.

Valve member 24 is reciprocally movable in cavity 16 between a first retracted position, illustrated in FIGUgg 2, a second retracted position illustrated in FIGURE 5 and an extended position illustrated in FIGS 3. Referring to FIGURE 2. in the first retracted position, outlet 32 of valve member 24 is blocked by sidewall 18 of body 7_2 such that no liquid enters flow path 34. Bottom diaphragm 20 serves to bias valve member 24 into the first retracted position. Referring to FIGURE
g, when liquid is required valve member 24 is gripped by recessed gripping portion 38, and a force exerted to overcome the biasing of bottom diaphragm 20 and manually move valve member 24 to one of extended position.
In the extended position, outlet 32 of valve member 24 protrudes out of cavity 16, thereby allowing liquid to flow from inlet 22 along flow passage 34 to outlet 32. Arrows 36 indicate the path of liquid. Referring to FIGURE 5. when used with a dispensing machine, pin valve 40 can be secured to coupling 48 which is inserted into body 12 of liquid dispensing valve 10. A force can be applied to pin valve 40 to move valve member 24 to the second retracted position. In the second retracted position, valve member 24 is pushed into cavity 16 thereby deforming bottom diaphragm 20 until first end 26 of valve member 24 clears inlet 22, so as to allow liquid to flow directly from inlet 22 bypassing flow passage 34 and outlet 32 and into flow conduit 42 of pin valve 40.
Arrows 36 indicate the path of liquid.
