     DETAILED DESCRIPTION OF THE INVENTION 
     The objects, features, and advantages of the inventive concept presented in this application are more readily understood when referring to the accompanying drawings. The drawings, totaling twenty-one (21) figures, show the basic components and functions of embodiments and/or methods of use. In the several figures, like reference numbers are used in each figure to correspond to the same component as may be depicted in other figures. 
     The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well as the singular forms, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and/or groups thereof. 
     The discussion of the present inventive concept will be initiated with  FIG.  1   . Displayed in  FIG.  1    is an exploded, “see-through” view of the preferred embodiment of the device, which is referred to as the “EZ Bottle”  1 . In the upper segment of  FIG.  1    there is displayed a detached canister top  11 . The canister top  11  shown in  FIG.  1    displays a contoured opening, termed a “loading portal”  12 . The loading portal  12  is shown partially covered by a slidable planar shutter  13 . The loading portal  12  is constructed as a sector having an exact contour corresponding to any of the respective openings of the three “chambers”  5 ,  6 ,  7  in a cylinder main body  2 . The chambers  5 ,  6 ,  7  are also readily shown in  FIG.  7   . In the preferred embodiment, the canister top  11  manifests internal threads  30 ( a ) about the inner circumference of the rim  14  of the canister top  11 . 
     In viewing  FIG.  1   , it is pointed out that any of several methods of attaching the canister top  11  to the cylinder main body  2  may be utilized, included, but not limited to, compatible threaded protrusions on both items, slanted protruding ridges, close-fit snap tolerance, matching coordinated slots and latches, or other means. This notation also applies to the methods of attaching the powder dispensers  21 ,  22 ,  23  to each other and/or to the interior of a cuff  25  of the cylinder main body  2 . In the preferred embodiment, when threaded segments are described or illustrated, the threaded segments comprise widely-spaced, angled threads  30 ( a ) of a certain pitch on all corresponding connectable components. 
     A horizontally rotatable, planar shutter  13  is constructed directly underneath the upper surface of the canister top  11 , and may be variably positioned in a plane parallel to the canister top  11 . In this manner, closing the shutter  13  provides a barrier against the spillage of any substances through the loading portal  12  of the canister top  11 . Upon a user rotating the shutter  13  counter-clockwise, the shutter  13  is placed out of view, underneath a portion of the upper surface of the canister top  11 . A nipple  15  is also affixed to the upper surface of the canister top  11 . The nipple  15  is constructed off-center of the canister  11  so as to enhance the flow of liquid into the mouth of an infant using the EZ Bottle  1  as a feeding method. 
     The center segment of  FIG.  1    displays the cylinder main body  2 , featuring three symmetrically spaced longitudinal dividers  8 . The dividers  8  separate the cylinder main body  2  into three discrete lengthwise chambers, being a first chamber  5 , a second chamber  6 , and a third chamber  7 . When in use, a person grasps the exterior  3  of the cylinder main bottle  2  then rotates the canister top  11  so as to align the contour of the loading portal  12  with one of the three chambers  5 ,  6 ,  7  of the cylinder main body  2 . At this point, the shutter  13  may be slidingly positioned so as to fully open the loading portal  12 , thereby permitting a liquid, powder, or other substance to be poured into the selected chamber  5 ,  6 ,  7 . 
       FIG.  1    also displays, in the center segment of the drawing, the outer surfaces  18  of two powder dispensers  22 ,  23 , being attached to the lower portion of the cylinder main body  2 . In the lower portion of  FIG.  1   , there is shown an exemplary, stand-alone powder dispenser  21 , directly below the cylinder main body  2 . It is to be noted that the two attached powder dispensers  22 ,  23  are both stacked and attached successively, to each other, and to the bottom of the cylinder main body  2 . All three powder dispensers  21 ,  22 ,  23  are of the exact same construction and dimensions. In the preferred embodiment, an upper powder dispenser  21 , center powder dispenser  22 , and lower powder dispenser  23  may be concentrically stacked vertically and securely attached to each other and to the cylinder main body  2 . 
       FIG.  2    is an illustration of the canister top  11  as previously shown in  FIG.  1   . Further shown is the rim  14  of the canister top  11  and an integral nipple  15 . In the preferred embodiment, the inner surface of the rim  14  is be constructed with threads  30 ( a ) compatible with similar threads placed exteriorly to the top of the cylinder main bottle  2 . In  FIG.  2   , the shutter  13  is shown partly open, having been moved to that position by means of a shutter ridge  13 ( a ), thereby exposing the loading portal  12 .
