Latest Patents

Majima holds a patent for a manual spray pump. This invention features a cylinder with varying diameters, which is integral to its design. The pump includes large and small pistons that are fitted in elastic contact with the inner wall of the cylinder, allowing for reciprocal movement. The small piston is designed to receive liquid pressure from the large piston, and a valve body at the top of the small piston works in conjunction with a valve seat of the large piston to create an opening valve. To enhance functionality, the small piston is equipped with an additional piston member or a mechanism to produce friction, which helps control its sensitivity under low liquid pressure. Additionally, the design incorporates an escapement hole to release residual liquid pressure, ensuring a sudden end to spraying and preventing operation under low pressure.
