MUMBAI, India, Jan. 2 -- Intellectual Property India has published a patent application (202541124737 A) filed by Sumukh Tallam; and Anusha Tallam, Bangalore, Karnataka, on Dec. 10, 2025, for 'dual-chamber bottle with telescopic bayonet lock for controlled mixing.'
Inventor(s) include Sumukh Tallam; and Anusha Tallam.
The application for the patent was published on Jan. 2, under issue no. 01/2026.
According to the abstract released by the Intellectual Property India: "The invention relates to dual-chamber liquid mixing technology and discloses a container having a top chamber (104) with a convex dome (110) featuring an internal L-shaped cutout and a bottom chamber (108) equipped with a convex dome including an overmolded silicone seal (114) and secondary O-ring seals. An outer sleeve (106) with a protruding plastic element (112) engages the L-shaped cutout to form a bayonet locking mechanism that prevents movement until a 10-30 rotational displacement disengages the lock, thereby permitting guided telescopic separation to create an annular mixing gap (120). Flow cutouts (116) are exposed during separation to enable controlled liquid communication, while one-way snap lock mechanisms (602) inhibit reverse movement, ensuring reliable mixing and dispensing of liquids."
