Abstract: By providing an adapter which is mountable to a product retaining container and incorporating seal cutting means, a dispensing system for chemical products retained in sealed containers is achieved which is capable of opening the sealed container and producing the transfer of concentrated chemical products from the storage container to a dilution vessel or tank in a completely closed, spill-free manner. Furthermore, the entire contents of the container can be transferred or, if desired, repeated transfer of measured dosage can be made in order to assure the dispensing of a precise quantity of product from the storage container to the dilution vessel. In the preferred embodiment, a product dispensing valve assembly, constructed for being opened by only mating authorized equipment, is securely affixed to the adapter which is mounted to the sealed container within which the desired chemical product is retained.

Abstract: By providing a securely locked product dispensing valve assembly mounted to a product bearing container which requires a specially constructed cooperating adapter for opening the valve assembly, a controlled dispensing system is realized which provides complete controlled distribution of any desired chemical product. By employing the present invention, only authorized personnel are able to open the container incorporating the valve assembly, enabling the contents to be transferred into only suitable containers incorporating the required adapter for unlocking the valve assembly. As a result, control over the distribution of the chemical product is attained and a completely closed loop, spill-free system is realized. In addition, a rinsing head is provided for being cooperatively associated with the product bearing container and valve assembly to enable complete cleaning of the container prior to recycling.
