MUMBAI, India, Nov. 14 -- Intellectual Property India has published a patent application (202434064822 A) filed by Majesty Holdings Co. Ltd., Guangdong, China, on Aug. 28, 2024, for 'all-plastic recyclable pressing pump.'
Inventor(s) include Liang, Peihui; Zhu, Maoyong; Liang, Jinkao; and Zhang, Yonglei.
The application for the patent was published on Nov. 14, under issue no. 46/2025.
According to the abstract released by the Intellectual Property India: "Disclosed is an all-plastic recyclable pressing pump, including a pump body, where the pump body is provided with a pump chamber, and a bottle locking cap is connected to the pump body; a liquid extraction assembly is provided in the pump chamber; the liquid extraction assembly includes a pump rod, and a bent nozzle is connected to an upper end of the pump rod; a liquid outlet channel is arranged in the bent nozzle, and a locking cap capable of limiting the liquid extraction assembly from disengaging from the pump chamber is provided in the pump chamber; a latching mechanism capable of limiting a downward movement of the bent nozzle when the bent nozzle stays in a latching position is provided between the pump rod and the locking cap; a scavenge port is arranged on a wall of the pump chamber; a lower end of the pump chamber is provided with a one-way valve capable of allowing the liquid in the bottle body to pass through and enter the pump chamber when the liquid extraction assembly moves; a lower part of the liquid extraction assembly is provided with a control valve capable of controlling the liquid in the pump chamber to be ejected from the liquid outlet channel; the locking cap is provided with a lower conical projection with a small upper part and a large lower part; the bent nozzle is provided with an upper conical projection with a large upper part and a small lower part; the pump rod between the locking cap and the bent nozzle is provided with an annular elastic piece capable of resetting the liquid extraction assembly after the liquid extraction assembly is pressed down; the annular elastic piece is provided with at least two outwardly protruding protrusions, and an inwardly recessed recess is arranged between two adjacent protrusions. The recesses replace openings to reduce an elastic coefficient of the annular elastic piece so that the annular elastic piece is more easily deformed and has a better rebound effect. There is no need to cut out openings to damage the structural strength of the annular elastic piece, which improves its service life and reduces the generation of transverse stresses, resulting in smoother movement."
