Latest Patents

Yamawaki holds a patent for a "Viscous liquid-dispensing container having a resilient follower." This invention allows for the easy extraction of almost all the contents of the container. The design features a liquid-dispensing section with a head and shoulder, along with inner and outer containers connected to the shoulder. The liquid-dispensing section includes a first check valve that permits only the extraction of liquid, while the outer container has a second check valve that allows for the introduction of exterior air. The inner container is designed to accommodate the viscous liquid, featuring an upper sleeve that is relatively hard and a lower bag made of a flexible thin film. As the liquid is extracted, the lower bag inverts and invades into the upper sleeve, depending on the reduction of liquid in the inner container.
