  • Patent number: 6220482
    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.

  • Patent number: 6170543
    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.

  • Patent number: 6092569
    Abstract: By employing a product dispensing head assembly securely mounted to a storage container, within which desired flowable material is retained, with the head assembly being movable into a plurality of alternate positions, the controlled, measured, dispensing and delivery of any desired flowable product is attained. In the preferred embodiment, the product dispensing head assembly incorporates automatic locking means which are automatically engaged when the product dispensing head assembly is in the closed position. Furthermore, a special dispensing coupling is preferably employed to effectively disengage the locking means, thereby providing assurance that no individual can obtain unauthorized access to the flowable material stored within the closed and sealed container.

  • Patent number: 5259423
    Abstract: By employing two independent, separate and distinct flow paths which are controllably sequentially opened during use in a single actuation operation, an error-free, spill-free flame and explosion proof liquid delivery/filling system is achieved. In the preferred embodiment, both flow paths are normally maintained in a closed, sealed configuration, requiring an actuation force to controllably, sequentially open the flow paths. In addition, by providing a cooperating, mating liquid transfer assembly, the container on which the liquid delivery/filling system is mounted can be refilled with safety and ease, completely eliminating spillage of the liquid. In this way, a fully integrated, cooperating, liquid flow controlling system is realized. Furthermore, a process for distributing toxic chemicals is disclosed which provides full control over the chemicals being distributed and prevents unwanted spillages, misuse, and mishandling of the chemicals in an unpressurized, gravity fed system.
