Fluid release mechanism for a chemically-inflatable bag

A cap for sealing an opening of a fluid-containing device of a chemically-inflatable bag comprising:

• a cap base, the cap base being directly and removably attached to the fluid-containing device proximate the opening, said cap base having a cap base width and a first cap base end;
• a cap tip connected to and extending from the cap base in an outward direction from the fluid-containing device, said cap tip comprising
• (1) an elongated tip portion having an elongated tip portion width,
• (2) a base tip portion having a base tip portion width being less than the cap base width at the first cap base end, a first base tip portion end, and a second base tip portion end, said base tip portion being positioned adjacent to the cap base at the second base tip portion end, and
• (3) a recessed tip portion being positioned between the elongated tip portion and the base tip portion and adjacent to the first base tip portion end, said recessed tip portion having a recessed tip portion minimum width being less than the elongated tip portion width and less than the base tip portion width,
• wherein breaking the cap tip at the recessed tip portion causes substantially all of the elongated tip portion to be removed from the cap tip and exposes the opening of the fluid-containing device, and
• wherein upon the breaking fluid from within the fluid-containing device exits into the chemically-inflatable bag and mixes with a reacting agent contained in the chemically-inflatable bag in order to inflate the chemically-inflatable bag.

A chemically-inflatable bag for a borehole plug comprising:

• a first reacting agent;
• and
• a fluid-containing device positioned within the chemically-inflatable bag, the fluid-containing device having an opening, a removable cap being directly and removably secured to the fluid-containing device, and a fluid contained therein,
• wherein removing the removable cap from the fluid-containing device exposes the opening of the fluid containing device and causes the fluid to exit into the chemically-inflatable bag and mix with the first reacting agent in order to inflate the chemically-inflatable bag.
