ABSTRACT:
A cap having two chambers provides a means for and method of decomposing or neutralizing a hazardous chemical residue in a container after it has been emptied at the point of consumption. One of the chambers is a screw cap which normally closes and seals the container prior to the consumption of the hazardous chemical. The other chamber contains a measured amount of a second chemical which decomposes or neutralizes the residue of the hazardous chemical. The other chamber may be sealed off by a rupturable membrane, a screw cap, a friction held stopper, or a tear-off top, any of which may be ruptured or removed at the time when the residue is to be decomposed or neutralized. In the preferred embodiment, a screw cap is removed from the second chamber and the cap is inverted and screwed onto the container rupturing the membrane in the process, thereby releasing the second chemical into the container.
