MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202511108581 A) filed by Jitendra Pal Singh; and Gunjan Singh, Pratapgarh, Uttar Pradesh, on Nov. 9, 2025, for 'unidrip: tamper-evident closure for sterile plastic liquid containers.'
Inventor(s) include Jitendra Pal Singh.
The application for the patent was published on Dec. 12, under issue no. 50/2025.
According to the abstract released by the Intellectual Property India: "The present invention provides a tamper-evident closure system for sterile plastic liquid containers, designed to maintain sterility, ensure safe fluid access, and offer clear evidence of first opening. The closure (100) comprises a monolithic cap (110) with an elevated port sealed by a peelable, pharmaceutical-grade aluminum foil (130). Beneath the foil lies an integral puncture-resistant membrane (120) of approximately 3 mm thickness, allowing penetration by a standard IV spike or hypodermic needle without coring. The cap is made of medical-grade polypropylene, the membrane of thermoplastic elastomer, and the foil has a tensile strength of 210-260 MPa. During Injection Stretch Blow Molding (ISBM), the cap is permanently fused to the bottle neck via thermal or induction sealing. The membrane is inserted before fusion, and the foil is heat-sealed afterward. The closure ensures sterile, tamper-evident protection, preventing contamination, spills, and moisture loss while maintaining pharmaceutical compliance."
