Abstract: A disposable foam dispensing kit for retaining a pair of aerosol cans, each containing separate fluid components of a foam system, in a portion relative to a bridge mechanism for simultaneously opening both aerosol can valves. The cans are supported in their operative position by a single carrier having detent formations for enabling snap action assembly of the cans with the carrier. The carrier includes a central post which extends as a tongue on which the bridge member is slidably mounted and ends at a pivot fulcrum to which an actuating cam lever is fitted by snap action.
