A reusable insert designed for off-the-shelf covered containers, such as infant feeding bottle having a storage compartment for powdered formula, a top opening (32) to the compartment, a bottom opening (36) to the compartment, closure (40) for closing the bottom opening (35), and an actuator (20) that is guided for vertical movement within the housing for operative engagement with the closure. The upper end of the actuator extends below the nipple which is attached to the infant feeding bottle so that the user can apply downward pressure on the actuator through the nipple. Downward movement of the actuator causes the closure to move from its upper closed position at the bottom opening to a lower open position spaced from the bottom opening of the housing to enable powdered formula to be released into the chamber of the infant feeding bottle.

[ I claim:] [1.]1. An insert for an infant feeding bottle having a chamber, an upper end for receiving a nipple assembly removably connected to the upper end of the bottle, said nipple assembly including an elastomeric nipple which has a bottom opening, said upper end having an upper access opening to the chamber and an annular rim surrounding the upper access opening, said insert comprising:(a) a housing having a compartment for storing powdered formula, a top opening to the compartment and a bottom to the compartment, said housing being adapted to be inserted into the chamber of said bottle and to be supported on the bottle so that the top opening of said compartment is exposed to the bottom opening of said housing is exposed to said chamber, said housing having an annular outer vertical surface at said bottom opening;(b) a closure being movable from an upper position for closing the bottom opening of said housing for isolating said compartment from said chamber and a lower position in which said closure is spaced from said bottom opening for connecting said chamber to said compartment and to the bottom opening of said nipple, said closure having an annular vertical wall located outside of said annular vertical surface when said closure is in the upper position, said closure having an annular elastomeric bead extending inwardly from said annular vertical wall for engaging said annular vertical surface in telescoping sealing relationship when said closure is in its upper position; and(c) an actuator having a lower end connected to said closure so that said closure and said actuator move as a unit said actuator having an upper end which extends above the top opening of said housing for being positioned below said nipple, one of said closure and said actuator being releasable connected to said housing so that said closure is releasable maintained in its upper position for sealing the bottom opening, said actuator being guided on said housing for vertical movement relative to said housing so that said actuator can be pushed downwardly from said nipple for moving said closure downwardly from its upper position to its lower position.
