referring to fig1 a - c , 2 a - c and 3 , according to an embodiment of the present disclosure , a bottle 101 cooperates with a lid 102 and ring 103 . the lid 102 includes a listing of times and / or days for administering medication , vitamins , and the like . the ring 103 includes a notch 104 , which cooperates with an indicator 105 disposed on the bottle 101 . referring to fig1 a , 2 a , and 3 , the bottle 101 and the cap 102 comprise a locking mechanism for securing the cap to the bottle . the locking mechanism comprises cooperating tabs 106 / 107 . referring to fig2 d , the lock mechanism further comprises a diaphragm 201 disposed inside the cap for applying a force against an upper part of the bottle in a closed position . the diaphragm 201 pushes the bottle 101 away from the cap 102 and thus engages the cooperating tabs 106 / 107 when the cap 102 is appropriately arranged . the number of tabs 106 / 107 and the position of the tabs 106 / 107 are arranged such that the listing , e . g ., a day - of - the - week indication , is aligned with the indicator 105 when the cap is in a locked position ( see for example , fig6 a - 1d ). referring to fig3 , an exemplary embodiment of the locking mechanism includes substantially square tabs 107 disposed on one of the bottle or the cap . the locking mechanism further includes a shaped tab 106 ( see fig2 a ), adapted to receive and secure the square tabs 107 . an opposing force is maintained between the cap 102 and bottle 101 , for example , by a diaphragm disposed in the cap , wherein the bottle deflects the diaphragm such that the diaphragm generates the opposing force . one of ordinary skill in the art would appreciate that other locking mechanisms may be used . optionally , a ring 103 is disposed under the cap 102 . the ring 103 rotates on to the cap 102 and engages into the indicator 105 when aligned with the notch 104 and depressed . referring to fig2 d , the ring 103 includes a rib 202 cooperating with a grove 203 ( see fig2 b ) in the cap 102 to secure the ring 103 to the cap 102 . the ring 103 is disposed having a friction fit , wherein rotation of the ring 103 is substantially prevented from freely rotating . when the cap 102 is rotated , the notch 104 and the indicator 105 stay engaged . this substantially prevents a user from putting the cap 102 back in the wrong position . fig6 a - d show a sequence of opening a bottle 101 . note that if the ring 103 is turned out of alignment with the indictor 105 on the bottle 101 , the indicator 105 cannot engage in the notch 104 , and the cap 102 cannot be depressed to disengage the tabs 106 / 107 and open the bottle 101 . accordingly , the ring 103 may be implemented as a further locking mechanism , substantially preventing opening of the bottle 101 , by disposing the notch 104 in a misaligned position with respect to the indicator 105 . in the exemplary embodiment shown in fig1 a and 3 , seven tabs 106 / 107 are disposed on each of the bottle 101 and cap 102 . this is an example of a bottle used where a dose is needed once per day . the indicator 105 and listing ( e . g ., see fig6 c , 601 ) may be disposed on the cap 102 or on the bottle 101 . where the listing 601 is disposed on the bottle , the listing 601 may rotated on the bottle 101 each time a cap 102 is depressed and turned in a direction to open the bottle 101 . the listing 601 rotates one increment each time the bottle 101 is opened . referring to fig7 , according to an embodiment of the present disclosure , a system may include a bottle 101 , a cap 102 , and an indicator 105 , without implementing a ring . the indicator 105 may be disposed on the bottle 101 or cap 102 , and be disposed opposed a listing , for example , of dates and / or times . further the indicator 105 may be provided in relief or as a graphic . having described embodiments for a bottle indicating a date or time period , it is noted that modifications and variations can be made by persons skilled in the art in light of the above teachings . it is therefore to be understood that changes may be made in the particular embodiments of the invention disclosed which are within the scope and spirit of the invention as defined by the disclosure .
a bottle includes an indictor and a listing of times and / or days for administering pills . the indicator may be disposed on a cap or on the bottle . the strip is disposed opposite the indicator ; on the bottle or the cap , respectively . the indicator and strip indicate a next prescribed time to take a pill or the last time a pill was taken .
