FLUID RELEASE MECHANISM FOR A CHEMICALLY-INFLATABLE BAG

摘要

Embodiments provide an apparatus for providing a nonlabor-intensive process for sealing an opening formed in the ground with a chemically-inflatable bag. The chemically-inflatable bag comprises two or more chemical reactants, one of which is a liquid reactant that is initially stored in a liquid-containing device. The liquid-containing device has a removable cap, which upon removal or breakage of the cap permits the liquid reacting agent to contact and react with another reacting agent. The chemical reaction produces carbon dioxide, which expands the chemically-inflatable bag from a collapsed condition to an inflated condition. In the inflated condition, the chemically-inflatable bag fills and protects the integrity of the formed cavity.

主权项

1. A cap for sealing an opening of a fluid-containing device contained within a chemically-inflatable bag comprising:
an attachment means for removably securing the cap to the fluid-containing device; and a tip portion extending from the attachment means and having a tip length; wherein the tip length is sufficient so as to provide a portion which is breakable such that upon breaking the tip length, 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.
