MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202631062889 A) filed by C. V. Raman Global University, Bhubaneswar, Orissa, on May 18, for 'spill-resistant oil dispensing spout with annular drip retention structure.'

Inventor(s) include Bhuvaneswari Kolusu; Smruti Rekha Swain; and Arka Ghosh.

The application for the patent was published on May 29, under issue no. 22/2026.

According to the abstract released by the Intellectual Property India: "The present invention discloses a spill-resistant oil dispensing spout with an annular drip retention structure designed to address the prevalent problem of post-pour oil dripping from conventional cooking oil bottle spouts. The invention comprises a cap body manufactured from food-grade High-Density Polyethylene (HDPE) through injection moulding, incorporating a centrally positioned V-shaped dispensing spout fabricated from stainless steel alloy SS304. The cap body integrates an annular recessed drip-retention region concentrically surrounding the base of the dispensing spout, a raised peripheral spill-containment wall circumscribing the outer boundary of the retention region, and a rear flow-blocking back cap element positioned rearward of the spout outlet. During active pouring, the rear back cap restricts oil discharge to a single controlled forward direction, preventing multidirectional splash and backward oil flow. Upon completion of pouring, residual oil dripping from the spout tip is captured passively within the annular retention recess under the action of gravity, preventing contact with the external bottle surface. The raised peripheral wall prevents overflow of collected oil during bottle handling. The invention operates entirely through structural geometry and natural physical forces without requiring valves, absorbents, springs, or any moving parts. All materials employed are food-grade and compatible with standard injection moulding and metal forming manufacturing processes, enabling costeffective mass production. The invention is applicable in household, commercial kitchen, and institutional food service environments, providing improved hygiene, reduced product wastage, and enhanced user convenience."
