Toy 'sippy bottle' now in 4-ounce version
September 1, 2008

TummyTickler fruit juice for young children now comes in a 4-ounce toddler version with a reusable, spill-resistant novelty cap.
The product, from In Zone brands, comprises a shrink-wrapped multipack of single-serve bottles with a toy-like topper. The topper is available as one of several Disney, HIT and Scholastic characters, among others. It features a spill-proof valve, making the bottle function like a sippy cup.
TummyTickler 11+1 packs (that is, 11 bottles plus the topper) are already being sold in Wal-Mart. An 8+1 version recently rolled out nationally at Target stores and other grocery outlets.
