Abstract

A baby bottle 10 with two separate compartments for storage of powdered baby formula 104 and water 106. Water 106 is stored in a bottle portion 12 and baby powdered formula 104 is stored in a cartridge assembly 14. The cartridge assembly 14 consists of a housing member 16, a seal member 18, a storage cylinder 20 and a nipple assembly 22. Nipple assembly is attached to the top of storage cylinder 20 which is disposed through the top of housing member 16. Seal member 18 is attached to the bottom of housing member 16 and engages an opposing mating surface on the bottom of storage cylinder 20, thus providing a releasable connecting means to disconnect the seal member 18 from the housing member by allowing the seal member to be turned by the storage cylinder. The bottom of housing member 16 is attached to the top of bottle portion 12. Seal member 18 provides an internal leakproof seal that can be released by external means at a desired time by rotating nipple assembly 22. As a result, storage cylinder 20 forces seal member 18 to detach itself from the bottom of housing member 16. The seal member 18 and powdered formula 104 both fall into water 106. The seal member 18 can provide a more efficient means of mixing the water 106 and powder 104 together while the bottle 10 is being shaken. Once thoroughly shaken, the liquid formula is consumed through the end of a nipple 72.
