Patent attributes
A viscous construction material tube cap and strapping apparatus includes an elastic strap. A construction material tube cap has dimension chosen to fit over a nozzle of a construction material tube, where the construction material tube cap defines a plurality of apertures having dimensions for passing the elastic strap. A base is dimensioned to fit over a bottom of the construction material tube. The base includes an air seal that substantially prevents air from entering into the bottom of the tube of construction material. The base also includes a feature on the outer surface of the base that is dimensioned to secure the elastic strap. The elastic strap has a length and an elasticity so that when inserted into the plurality of apertures in the construction material tube cap and into the feature on an outer surface of the base, the elastic strap forces the construction material tube cap down on the nozzle of the construction material tube when the elastic strap is connected to the base and the cap is fit over the nozzle of the construction material tube and the base is fit over the bottom of the construction material tube, thereby tightly sealing the nozzle.
