Abstract
A cap for curable material dispensing containers prevents the material from curing after opening the dispensing nozzle. Thus, when mounted on a partially-dispensed container, the nozzle cap preserves flowable materials such as air-cured glues, sealants, caulks, etc. In particular, a deformable sealant in the cap remains pliant, conforming in and/or around the nozzle tip to create a seal. A retention member frictionally grips the nozzle to prevent inadvertent release of the cap, yet accommodates nozzle tips cut to varying lengths.
Claims20
A container for dispensing one of a glue, sealant and caulk, comprising:
- a hollow tube containing the glue, sealant or caulk;
- a nozzle at one end of the tube, the nozzle having a tip with an outlet to dispense the glue, sealant or caulk, and
- a sealing cap including a hollow elongate body having an open end and a closed end and an interior space shaped to encompass a portion of the nozzle including the tip and a deformable sealant located within a portion of the interior space toward the closed end and sealing the orifice.
A sealing cap for a container holding a flowable and curable material, the container further having integral, one-piece elongate dispensing nozzle with an outer surface and a tip, the sealing cap comprising:
- a hollow elongate body having an open end and a closed end and an interior space shaped to encompass a portion of the nozzle including the tip;
- a deformable sealant located within a portion of the interior space toward the closed end;
- and
- a retention member located within the interior space configured to frictionally engage the outer surface of the elongate nozzle when the nozzle tip is insert into sealing contact with the deformable sealant.
A method of selectively sealing an open nozzle tip of a partially dispensed container of flowable and curable material, the container having an elongate, integrally formed nozzle with an outer surface, the method comprising:
- placing a deformable sealant material within a closed end of a cap shaped to receive the outer surface and the open nozzle tip;
- engaging the cap over the open nozzle tip;
- making sealing contact between the open nozzle tip and the deformable sealant material;
- and
- engaging at least one projection of the cap onto the outer surface of the elongate, integrally formed nozzle.
