Small pic caulk window

Products like Caulk and Silicone are traditionally sold and dispensed in either small aluminum tubes and larger caulk tubes. Both options utilize tapered plastic nozzles to dispense the material. The issue we are facing is that once these tubes opened and used, air and moisture begin to cure the products in the nozzles making them difficult to dispense in subsequent uses.

We are looking for novel new nozzle designs or solutions to prevent the curing of silicone in nozzles and ensure that the caulk and silicone inside are kept fresh. This would involve preventing air and moisture from entering the nozzle and affecting the product.
