A child-resistant package design with an opening mechanism which relies on cognitive skills rather than strength.
How It Works:
The effectiveness of this novel child-resistant packaging closure technology relies on differences in the ways adults and young children think. The product was designed on the model of a simple combination lock mechanism. A two-piece double-locking cap requires a sequence of two turns to open it.
Competitive Advantage:
Ease of use, particularly for adults. Does not require strength or manual dexterity.
Examples of Applications and Markets:
Child-resistant packaging for pharmaceuticals and hazardous household substances. This closure will work effectively on all sizes of containers, liquids or solids. (Sample package can be provided on request).
Status:
One embodiment of this technology (WiseCap), has been tested with the procedures from the Poison Prevention Packaging Act and passes the full requirements. WiseCap is an R&D Magazine R&D-100 Award winner and has been licensed by a major pharmaceutical company for non-exclusive worldwide application. While YES was paid in full for the license, a change in the licensee's product strategy precluded commercialization of the closure as planned. The patents are available for exclusive or non-exclusive license or for outright sale.
