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.

Patent Acquisition Opportunity

The Vapor Shield patent is currently available for acquisition by a qualified industrial buyer.

The objective is to place the technology in the hands of an organization with the manufacturing capability, market access and resources required for large-scale commercialization.

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 for integration into packaging and dispensing systems and may be adapted to a variety of industrial applications.

Acquisition Opportunity

Kohlberg Innovation is seeking the sale and transfer of the Vapor Shield patent to a suitable industrial owner capable of bringing the technology to commercial scale.

The intended structure includes:

• full transfer of patent ownership

• negotiated upfront consideration

• continuing revenue participation linked to future commercial sales.
