Abstract: A pressure regulator with a serviceable lock is provided. The pressure regulator with a serviceable lock including a housing body having an inlet and an outlet with an internal cavity disposed therebetween. The housing body including an upper housing and a lower housing that are removably couplable to one another so that the housing body can be moved between an open position and a closed position. The first housing having a latch that is configured to engage with a channel on the second housing to prevent the rotation of the first housing relative to the second housing when the housing body is in the closed position.

Abstract: This invention provides a capless retractable cosmetic dispenser applicable to all types of cosmetic fluids and capable of self-sealing and substantially preventing vapor fluid from evaporating through the valve when the applicator is in the retracted position. The retractable dispenser includes a front cowling with an opening to allow the applicator to move in and out of the opening. Adjacent to the opening and within the front cowling is a valve capable of moving linearly within the front cowling. The valve substantially seals the cosmetic fluid and applicator from outside air and the release of vapor pressure from within the valve when the applicator is in a retracted position.
