  • Patent number: 4790981
    Abstract: A device is disclosed to enable the safe insertion and removal of a container of solid or powdered detergent cleaner into a detergent dispenser such as for a dishwasher. The device includes a bowl portion and a central, upstanding water spray outlet near the bottom of the bowl which ejects water into the container to remove the detergent from the container, or from bulk powder fed into the bowl.The spray outlet is occluded by a cover plate which is mounted on a screen which retains the powdered detergent, and the cover plate functions to occlude the spray outlet and horizontally deflect the water spray. This prevents the ejection from the dispenser of water, steam, detergents and chemical solution.

  • Patent number: 4666682
    Abstract: A device is disclosed for safely inserting and removing a container of solid or powder detergent cleaner into a detergent dispenser such as for a dishwasher. The device includes a bowl portion and a central, upstanding water spray outlet near the bottom of the bowl which ejects water into the container to remove the detergent from the container, or from bulk powder fed into the bowl.One or more fingers is attached to the inside of the bowl and is biased inwardly by a spring to occlude the spray outlet. When the container of detergent is inserted into the bowl, it biases the finger outwardly and exposes the spray outlet to the detergent. Upon removal of the container from the bowl, it will move out of contact with the finger, which is again biased inwardly by the spring to occlude the spray outlet and protect the operator.Dissolved detergent and wet powder and particles are deposited on, and seep through, a perforated plate or screen adjacent the spray outlet.
