Abstract
A container for institutional detergents, preferably tablets, includes a rigid large screened base and a flexible plastic film sidewall heat bonded to the peripheral surface of the base. The container is filled, preferably from its top portion, with tableted detergent and closed with a single heat seal along the top surface of the wall of the container. The screen surface is then closed with a removable, peel-off seal or removable cap. The upper portion of the container will include a handle which makes it easy to transport the container and place it into a dispenser for use. In use, a water nozzle will spray upwards onto the surface of the screen base through the holes in the screen, dissolving detergent and allowing the solution to pass downwardly to a drain, which directs it to a ware washing apparatus.
