Abstract

A feed bag construction is provided comprising a feed bag, a first conduit sealed to the feed bag, a second conduit sealed to the interior of the feed bag for supplying wash reagent to the feed bag and a one piece cap that is removably mounted on the first conduit. The first conduit is provided with a hand operated butterfly valve to open or close the conduit.

Claims

1. A feed bag construction consisting essentially of a bag sized to store a desired amount of powder reagent, a first conduit formed at a first lowermost end of the bag, the first conduit being used to empty the bag of contents, a valve positioned within the first conduit for controlling passage of powder reagent through the first conduit, the valve being mounted on a shaft and connected to a lever, the lever being capable of being pivoted to extend away from the first conduit during use, the lever effecting rotation of the valve about shaft thereby to selectively open or close the first conduit, a cap enclosing the first conduit, valve and lever when pivoted toward the first conduit, and a second conduit located at and sealed to a second end of the bag opposite the first end of the bag for introducing wash liquid into the bag to remove, by rinsing, residual powder reagent from the bag through the first conduit, the second conduit extending across the length of the second end of the bag, the second conduit having a connector positioned outside the feed bag on one side of the second conduit and a seal adjacent another side of the second conduit, the second conduit having multiple outlets spaced along its length, and the bag being asymmetrical in shape having a first lateral side wall, the first lateral side wall extending vertically between the conduit on the first end of the bag to the second end of the bag and a second lateral side wall opposite the first lateral side wall, the second lateral side wall having a tapered portion extending outwardly at an angle from the first conduit and a second portion extending vertically between an end of the tapered portion farthest from the first conduit and the second end of the bag.

2. A feed bag construction consisting essentially of a bag sized to store a desired amount of powder reagent, a first conduit formed at a first lowermost end of the bag, the first conduit being used to empty the bag of contents, a valve positioned within the first conduit for selectively controlling passage of powder reagent through the first conduit, the valve being mounted on a shaft and connected to a lever, the lever being capable of being pivoted to extend away from the conduit during use, the lever effecting rotation of the valve about shaft thereby to selectively open or close the first conduit a cap enclosing the first conduit, valve and lever when pivoted toward the first conduit, and a second conduit located at and sealed to a second end of the bag opposite the first end of the bag for introducing wash liquid into the bag to remove, by rinsing, residual powder reagent from the bag through the first conduit, the second conduit extending-across the length of the second end of the bag, the second conduit having a connector positioned outside the feed bag on one side of the conduit and a seal adjacent another side of the conduit, the second conduit having multiple outlets spaced along its length, and the bag being asymmetrical in shape having a first lateral side wall, the first lateral side wall extending vertically between the conduit on the first end of the bag to the second end of the bag and a second lateral side wall opposite the first lateral side wall, the second lateral side wall having a tapered portion extending outwardly at an angle from the first conduit and a second portion extending vertically between an end of the tapered portion farthest from the first conduit and the second end of the bag.
