Removable closure cap for containers containing air-curable material

A method of preventing any remaining air-curable flowable material in a container with a cut nozzle end or applicator tip from curing upon exposure to air comprising forming a force-fit or press-fit grip airtight seal between a removable cap and the cut nozzle end or applicator tip of the container, wherein the removable cap comprises an outer surface and an inner surface:

• the outer surface comprises a tapered upper cylindrical portion with a closed top end and two opposing wings or handles, and a lower cylindrical portion of uniform diameter with an open bottom end capable of receiving the cut nozzle end or applicator tip of the container containing air-curable flowable material;
• and
• the inner surface comprises a plurality of spaced apart internal annular grip rings, each of said grip rings runs parallel and horizontal to another of the plurality of grip rings that decrease in diameter from the bottom of the opposing wings or handles to the top of the cap and the lower cylindrical portion of uniform diameter with an open bottom end,
• wherein the internal annular grip rings of the cap allow for a force-fit or press-fit grip airtight seal of the cap to the cut caulking tube nozzle when a user applies a pressing force on the wings or handles of the outer surface of the cap;
• wherein the cap is removable from the cut caulking tube nozzle by application of a pulling force on the wings or handles of the outer surface of the cap thereby breaking the airtight seal and allowing removal of the cap, and wherein the remaining air-curable flowable material in the container after removal of the cap is suitable for application through the cut nozzle end or applicator tip to a work surface;
• and
• wherein the lower cylindrical portion of uniform diameter comprises a lower portion with an inner and outer surface, and the lower portion extending below the two opposing wings or handles to first receive the cut calking tube nozzle, and the two opposing wings or handles extending radially beyond the outer surface of the lower portion.

A removable cap for forming a force-fit airtight seal when applied to a cut nozzle end or applicator tip of a container containing air-curable flowable material, the cap comprising an outer surface and an inner surface:

• the outer surface comprises a tapered upper cylindrical portion with a closed top end and two opposing wings or handles, and a lower cylindrical portion of uniform diameter with an open bottom end capable of receiving the cut nozzle end or applicator tip of the container containing air-curable flowable material;
• and
• the inner surface comprises a plurality of spaced apart internal annular grip rings, each of said grip rings runs parallel and horizontal to another of the plurality of grip rings that decrease in diameter from the bottom of the opposing wings or handles to the top of the cap and the lower cylindrical portion of uniform diameter with an open bottom end, wherein the internal annular grip rings of the cap allow for a force-fit or press-fit grip airtight seal of the cap to the cut nozzle end or applicator tip of a container containing air-curable flowable material when a user applies a pressing force on the wings or handles of the outer surface of the cap, and wherein the cap is removable from the cut nozzle or applicator tip of the container containing air curable material by application of a pulling force on the wings or handles of the outer surface of the cap thereby breaking the airtight seal and allowing removal of the cap thereby allowing any of the air-curable flowable material in the container to be applied a work surface;
• and
• wherein the lower cylindrical portion of uniform diameter comprises a lower portion with an inner and outer surface, and the lower portion extending below the two opposing wings or handles to first receive the cut calking tube nozzle, and the two opposing wings or handles extending radially beyond the outer surface of the lower portion.
