the present disclosure generally provides a baby formula mixing system that preserves the integrity of the formula until feeding is desired , and provides a means for quickly mixing the formula . fig1 generally illustrates a portable preservation and mixing system 100 . it should be understood that system 100 shown in fig1 is for illustrative purposes only and that any other suitable system or subsystem could be used in conjunction with or in lieu of system 100 according to one embodiment of the present disclosure . system 100 may comprise a preservation and mixing attachment 120 that may be employed to preserve baby formula in powder form within a baby bottle 180 used for feeding . the baby formula can be easily mixed at the time of desired feeding . the preservation and mixing attachment 120 may generally include a formula retention compartment 122 fixedly coupled vertically to a hollow compartment 124 , and a plug 126 horizontally therebetween . in one embodiment , formula retention compartment 122 may be integrally formed with hollow compartment 124 . in other embodiments , formula retention compartment 122 may be connected or otherwise coupled to hollow compartment 124 in any manner that fixedly secures formula retention compartment 122 to hollow compartment 124 , including using male and female coupling adapters , ball and socket attachment , adhesive , glue , buckle , or using other suitable fastening materials , or any combination thereof . in an embodiment , the formula retention compartment 122 may be adapted to removably couple to a baby bottle top 182 and the hollow compartment 124 may be adapted to removably couple to a baby bottle container 184 . the preservation and mixing attachment 120 may further comprise a pushrod 132 slidably disposed within a channel 134 and through a grommet 136 , employed to disengage plug 126 , and thereby releasing the powdered formula for mixing . optionally , a gasket 140 may be included to provide a better seal between the hollow compartment 124 and the baby bottle container 184 . it should be understood that the pushrod 132 shown in fig1 is for illustrative purposes only and that any other suitable mechanism could be used in conjunction with or in lieu of the pushrod 132 according to one embodiment of the present disclosure . in one embodiment , the pushrod 132 may have an angled surface that matches an angled surface of the plug 126 , as shown in fig1 . this configuration allows the horizontal movement of the pushrod 132 to cause the vertical movement of the plug 126 . alternatively , the pushrod 132 may be directed at a downward angle , such that one end of the pushrod 132 is moved downward , as shown in fig5 . in alternative embodiments , the pushrod 132 may be configured as a key turn mechanism by having a flat handle at one or both ends suitable for rotation , and a paddle extending from the midsection of the pushrod 132 to make contact with the plug 126 when rotated . the pushrod 132 may be replaced operationally by a v - shaped strap attached to the inner walls of the formula retention compartment 122 . when the formula retention compartment 122 is squeezed , the v - shaped strap collapses , causing downward movement at its vertex to release the plug 126 . other suitable mechanisms or a combination thereof may be employed to release the plug 126 . in operation , the user first resets the pushrod 132 by pushing on the end of the pushrod 132 opposite the end that is pushed to release the plug 126 . the user next inserts the plug 126 into place through the hollow compartment 124 , such that the plug 126 creates a barrier between the formula retention compartment 122 and the hollow compartment 124 . the user then fills the baby bottle container 184 with water . the user next secures the preservation and mixing attachment 120 to the baby bottle container 184 through the hollow compartment 124 . the user then disburses powdered formula into the formula retention compartment 122 . finally , the user secures the baby bottle top 182 to the preservation and mixing attachment 120 through the formula retention compartment 122 . when feeding is required , the user pushes the pushrod 132 from the outside of the preservation and mixing attachment 120 , which causes the plug 126 to disengage from the locked position and release the powdered formula through the hollow compartment 124 and into the baby bottle container 184 . in one embodiment , the plug 126 also releases into the baby bottle container 184 to act as an agitator to assist in mixing the powdered formula and the water . it should be understood that the operational steps described herein are for illustrative purposes only and that any other suitable method or sub - method could be used in conjunction with or in lieu of the steps described herein according to one embodiment of the present disclosure . it should also be understood that the steps described herein could be performed in any suitable order or manner . fig2 depicts an exploded view of system 100 of fig1 according to one embodiment of the present disclosure . in one embodiment , the preservation and mixing attachment 120 may include baby bottle top coupling threads 128 located on the exterior surface of the formula retention compartment 122 to allow the formula retention compartment 122 to removably couple to the baby bottle top 182 , and baby bottle container coupling threads 130 located on the interior surface of the hollow compartment 124 to allow hollow compartment 124 to removably couple to the baby bottle container 184 . it should be understood that the preservation and mixing attachment 120 may be removably coupled to any of a variety of baby bottles 180 available in the market . more particularly , the baby battle top coupling threads 128 and the baby bottle container coupling threads 130 can be sized to fit the thread pattern of any desired baby bottle 180 available to consumers . fig3 illustrates a bottom plan view of the preservation and mixing attachment 120 of system 100 demonstrating plug 126 in the engaged or locked position according to one embodiment of the present disclosure . in one embodiment , the plug 126 may be a compression fit stopper employed to prevent the flow of powdered formula from the formula retention compartment 122 into the hollow compartment 124 and the baby bottle container 184 before feeding . the compression fit can be done by making both the stopper and the opening it fits within slightly tapered , or by having a small lip on the plug which is wider than the opening , as shown in fig1 . in alternative embodiments , as illustrated in fig5 , the plug 126 may be an inverted rubber stopper . an inverted rubber stopper is a spherical cap having an elastomeric body that is defined primarily by a first surface and a second surface . the elastomeric body is selectively positionable between a normal orientation , where the first surface faces outwardly , and an inverted orientation , where the second surface faces outwardly . in the inverted orientation , the spherical cap stores energy and stretches to an increased diameter to assist in forming a seal . when the inverted spherical cap is touched with a certain degree of force , the spherical cap reverts back to the normal orientation , thereby releasing the stored energy . in such embodiments , plug 126 is inserted to engage the grip 138 in the inverted orientation , and thereby create a barrier between formula retention compartment 122 and hollow compartment 124 utilizing the stored energy and increased diameter of the inverted plug 126 . when the force of the pushrod 132 is employed to disengage plug 126 , plug 126 is disengaged from the grip 138 and returns to the normal orientation . in one embodiment , when the plug 126 is disengaged , plug 126 drops through the hollow compartment 124 and into the baby bottle container 184 , thereby releasing the powdered formula from the formula retention compartment 122 through the hollow compartment 124 and into the baby bottle container 184 . the plug 126 may then assist in mixing the powdered formula with the water located in the baby bottle container 184 , as the user swirls or shakes the baby bottle 180 . in an alternative embodiment , the plug 126 may be partially coupled to the preservation and mixing attachment 120 , such that when the plug 126 is disengaged it allows the powdered formula to release from the formula retention compartment 122 into the baby bottle container 184 but the plug 126 , itself , does not fall into the baby bottle container 184 . fig4 generally illustrates a top plan view of the preservation and mixing attachment 120 of system 100 demonstrating the pushrod 132
