ABSTRACT:
A reusable insert designed for off-the-shelf covered containers, and more specifically for baby bottles. The insert forms a storage compartment and which keeps the ingredients separated in the container. It is designed to allow the ingredients to be mixed in the same container and dispensed without removing the cover from the container. The insert generally includes a dry chamber housing 30, a chamber seal 40, and a means to release the chamber seal such as a push rod 20. When used with a baby bottle, the insert slides into the bottle portion 50. A flange at the top of the dry chamber housing 30 prevents it from moving too far into the bottle and still allows the nipple assembly 10 to be attached directly to the bottle portion 50. When the nipple assembly 10 is screwed in place, the flange is pinched between the nipple assembly 10 and bottle portion 50, forming a leak-proof seal. The dry chamber housing 30 and chamber seal 40 together form a cup-like container which stores the powdered formula prior to the ingredients being mixed. The means to release the chamber seal, in this case a push rod operates through the nipple 11 with either a push action or a combination of push/rotary action. The insert containing powdered formula slides into the open neck 51 of the bottle portion 50 containing a pre-measured amount of water and the nipple assembly 10 is screwed in place. To mix the ingredients, the user pushes on the nipple 11 which displaces the chamber seal 40 and provides a passage for water and formula to combine in both the bottle portion 50 and the dry chamber housing 30. The bottle is then shaken and the formula is dispensed. Other designs for the chamber seal 40 and the means to release the chamber seal are specified.
