Abstract
A product for the building industry includes a container having opposed transparent sidewall portions and a transparent caulking compound contained therein so that the appearance of a substrate surface with the caulking compound may be previewed before actual application of the caulk. A dispensing nozzle is provided at a downstream end and has a resealable cap. The container has a flexible sidewall that is flattened at an upstream end to form a region of reduced thickness so that a mass of caulking compound therein has a flattened configuration with this mass confined between the facing transparent sidewall portions. Preferably the entire sidewall is transparent and has index markings correlated to available bead length of the caulk remaining in the container. The flexible sidewall permits manual dispensing and allows a crease to be made thereby forming a preview packet.
