PresSure Lok provides controlled dispensing of liquid products such as shampoos, personal care products, detergents, energy products, beverages and condiments. This all-in-one package combines a flexible pouch and self-contained flexible fitment, eliminating the need for a separate dispensing component. The user squeezes the flexible pouch to open the seal, allowing liquid product to flow into the dispensing chamber. Upon releasing pressure, the package automatically reseals itself for future use. The proprietary sealing mechanism allows the flexible package to lie on its side, or hang upside down, without unintentional dispensing. The package is expected to serve as a viable alternative to blow-molded bottles.
