Vapor Shield –

Patented Self-Sealing Membrane Technology – Acquisition Opportunity

Protected by a Swedish patent

Handling volatile liquids often presents a practical challenge: preventing evaporation and limiting exposure to vapors while still allowing convenient dispensing from containers that are opened repeatedly during normal use.

Vapor Shield is based on a patented self-sealing membrane concept designed to address this challenge.

The Technology

The invention relates to a functional membrane element integrated into a container closure or dispensing system.

When pressure is applied to the container, the membrane allows liquid to be dispensed. When the pressure is released, the membrane automatically returns to its closed position, limiting evaporation and reducing vapor release.

This passive mechanism operates without springs, valves, or electronic components and can be implemented using standard materials commonly used in packaging and dispensing systems.

Key Functional Characteristics

  • pressure-responsive opening

  • automatic self-sealing after dispensing

  • reduced evaporation of volatile substances

  • limited vapor exposure during handling

  • simple passive mechanical principle

Potential Application Areas

The technology may be applicable in systems handling volatile liquids, including:

  • chemical and solvent containers

  • adhesives and sealants

  • laboratory reagents

  • cleaning and disinfectant solutions

  • controlled dispensing systems

The membrane feature can be adapted to various container formats depending on the application.

Benefits

Reducing evaporation can contribute to:

  • improved product stability

  • reduced chemical exposure

  • improved workplace safety

  • reduced material waste

  • extended usability of volatile liquids

Patent Status

The technology is protected by a granted Swedish patent that has been in force for more than ten years and covers a specific functional membrane feature enabling the self-sealing mechanism.
The patented principle is intended to be adapted and engineered for integration into existing packaging and dispensing systems.

Acquisition Opportunity

Kohlberg Innovation is currently exploring the commercial acquisition of the patent by a suitable industrial partner.

The intended structure includes:

  • full transfer of patent ownership

  • negotiated upfront consideration

  • a small continuing revenue participation linked to commercial sales
