This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,493.

Summary of the Inventive Concept

This inventive concept applies the core technology of blister packs to novel applications in environmental and food monitoring, enabling efficient and effective detection of pollutants, spoilage, and contamination.

Background and Problem Solved

The original blister pack patent was limited to medicinal products. However, the innovative design and production process of blister packs can be leveraged to address pressing issues in environmental and food monitoring. The new inventive concept tackles the problem of detecting environmental pollutants, food spoilage, and water contamination, providing a solution that is efficient, cost-effective, and easy to use.

Detailed Description of the Inventive Concept

The blister pack-based system for environmental monitoring comprises a blister pack containing sensor strips that absorb environmental pollutants. The tool for producing the blister pack ensures accurate and consistent formation of the blister pockets. Similarly, the blister pack-based system for food monitoring includes strips of active material that release indicator gases upon exposure to spoiled food. The blister pack is sealed to enclose the strips, allowing for easy detection of spoilage. The system for controlling humidity in a storage container utilizes desiccant strips within a blister pack, while the system for monitoring water quality employs test strips that release indicator chemicals upon exposure to contaminated water.

Novelty and Inventive Step

The new inventive concept lies in the application of blister pack technology to environmental and food monitoring, which is a significant departure from the original medicinal product-focused patent. The inventive step resides in the adaptation of the blister pack design and production process to accommodate novel sensor strips, active materials, desiccant strips, and test strips, enabling the detection of environmental pollutants, food spoilage, and water contamination.

Alternative Embodiments and Variations

Alternative embodiments may include using different materials for the blister pack or sensor strips, modifying the shape and size of the blister pockets, or incorporating additional features such as wireless connectivity or data logging. Variations may include adapting the blister pack design for specific environmental or food monitoring applications, such as detecting heavy metals or pesticides.

Potential Commercial Applications and Market

The blister pack-based systems for environmental and food monitoring have significant commercial potential in industries such as environmental consulting, food safety, and water quality management. The market for these systems is substantial, driven by growing concerns about environmental sustainability and food safety. The inventive concept offers a competitive advantage by providing a cost-effective, efficient, and easy-to-use solution for detecting environmental pollutants, food spoilage, and water contamination.
