The Clasper™ provides a unique packaging solution for boundary-pushing food, beverage, pharmaceutical, nutraceutical, industrial and household chemical products. The Clasper concept enables two different products to be consumed in sequence or mixed together and then consumed.

The first commercialization of this new technology was the recent introduction of Yumix portable, shelf-stable line of cocktails. The Clasper technology combines two polyethylene terephthalate (PET) containers, with the bottom container snapping into the base of the larger top bottle. Although the cocktail line launch features a bottom container that holds 50 mL of premium alcohol and a main bottle containing 6.5 oz of hot-filled, shelf-stable juice, the size and shape of the compartments can be altered to accommodate a variety of other applications.

The Clasper package concept is the brainchild of Yumix founder Alex Garner and was engineered by Plastic Technologies, Inc. (PTI). The challenge for PTI was to find the right geometry and bottle weight to keep the dimensions within the appropriate tolerances so that the snap fit was consistently achieved, but yet have the containers be easily separable by the consumer.

Although the Clasper package was originally designed for a hot-fill application, modifications can be made to accommodate other process types. The containers can also be decorated via a shrink sleeve, which provides added visual appeal and usage instructions.
