Abstract
There is disclosed a closure comprised of a valve, a base unit and an upper unit. The base unit has a base surface with a peripheral skirt. The base surface has an aperture with a cylindrical section extending above and below the base surface. The cylindrical section has an aperture therethrough. The upper unit has an upper surface and an aperture adapted to align with the aperture of the cylindrical section of said base unit. The upper unit has a lid to cover the apertures in the base unit cylindrical section and the upper unit. A lid inner top surface has two projecting seals, one to maintain the valve closed when the lid is closed and the other to provide a seal when the lid is closed. and a latch mechanism attaches the base unit to the upper unit. A preferred latch mechanism comprises a projection and an interfitting recess, one being on the base section and the other on the upper section. The lid top surface preferably has an essential horizontal top surface. In a preferred embodiment the valve is a polymeric valve located in the aperture between the base unit and the upper unit and held in place by contact with both the base unit and the upper unit. The rheology of the product in the container and the characteristics of the valve are coordinated so that the product will be fully contained by the valve regardless of the orientation of the container, including being inverted.
