Inflatable down hole bag with inflation reagent release

A container for release of a reactive substance into an inflatable down hole bag, comprising:

• a container body for holding one or more substances;
• and
• a closure for keeping the one or more substances in the container when the closure is in an inoperative state, the closure also for releasing the one or more substances from the container when the closure is in an operative state;
• wherein release of the one or more substances causes an inflation fluid producing reaction within the inflatable body, thereby inflating the inflatable body;
• wherein, the container comprises at least two separated chambers, each chamber for holding a respective one of the substances, wherein, the closure comprises a stopper or stoppers for closing a respective opening to each of the chambers.

A method of inflating a down hole bag, comprising:

• providing an inflatable bag having an inflatable body for holding an inflation fluid;
• the bag comprising a container for holding two or more substances in at least two separated chambers, each chamber for holding a respective one of the substances, the container being disposed inside of the inflatable body, the container comprising a closure which comprises a stopper or stoppers for closing each respective opening of the chambers;
• activating an actuator of the container so as to change it from an inoperative state where the one or more substances in the container a held therein to an operative state wherein upon the change from the inoperative state to the operative state removes each stopper or stoppers from the respective opening so as to release each of the substances of each respective chamber of the container into the inflatable body;
• wherein release of the one or more substances causes an inflation fluid producing reaction within the inflatable body, thereby inflating the inflatable body.
