combination of elements , functions , steps or acts are in some way inherently mutually exclusive . the drawings featured in the figures are for the purpose of illustrating certain convenient embodiments of the present invention , and are not to be considered as limitation thereto . term “ means ” preceding a present participle of an operation indicates a desired function for which there is one or more embodiments , i . e ., one or more methods , devices , or apparatuses for achieving the desired function and that one skilled in the art could select from these or their equivalent in view of the disclosure herein and use of the term “ means ” is not intended to be limiting . as used herein the term “ bottle ” refers to a container for holding a liquid designed for drinking such as water which has an elongated body with an interior space for placing the liquid . the bottle can be a typical reusable water bottle , a baby bottle or any other reusable type bottle for placing a liquid for drinking . the bottle will also have an exterior surface and a neck portion which may or may not be narrower than the elongated body . the bottle will also have a cap portion covering a top opening where liquid can be added to the bottle and there will be a bottom portion of the interior space . in general water bottles , whether for cycling , exercising , just drinking water , and the like , come primarily in polymeric versions made from materials that are safe to store both water and liquid drink mixes in . that is , the use of “ food grade ” material is useful . while metal food grade containers such as stainless can also be utilized , when cost is an issue , polymeric containers will normally be the embodiment utilized . typically , water bottles are utilized just for containing water and if a drink powder is to be used with the water bottle , a dosage of the drink powder is added through the top opening of the bottle unlike the present invention . as used herein the “ top portion outer surface ” refers to the upper half of the bottle , in one embodiment the upper third , and in another embodiment just the cap . outer surface has its normal meaning and in general , refers to an area above the liquid in the bottle such that gravity can add a solid to the liquid for suspension or dissolution . the bottle can have a closable drinking spout , for example , as shown in the figures or any kind of mechanism for drinking the liquid in the bottle . the use of very inexpensive plastics are utilized in the construction of disposable bottles such as water bottles that are thin and designed not to be reused , though most can for a small number of refills . on the other hand , reusable water bottles are made of thicker materials and designed to be washed and reused , for example , can be placed in the dishwasher for cleaning and sterilizing . those skilled in the art of drinkable liquid bottles can select the most appropriate plastics and construction materials for constructing a bottle of any kind . as used herein the “ compartment ” of the present invention is an area large enough to contain a dosage of solid such as a tablet , powder or the like to flavor or dose with a desired consumable like vitamins , food , minerals or the like by dissolving or suspending or the like in a liquid such as water placed in the remainder of the inner space of the bottle . the plurality of compartments each have a top portion and a bottom portion and are positioned within the top portion in the upper half of the bottle , at least a portion of which is on the outer surface and a bottom portion at least a portion positioned in the interior space . in one embodiment the compartments are positioned in the cap of the bottle , for example , as shown in the figures but the cap mounting is not intended to be the only position . the exact position is designed such that one can add the solid to the top portion and the bottom portion of the compartment delivers the solid to the interior space to dissolve or suspend in the liquid in the inner space . the top portion has an opening for addition of the solid to the compartment and a lid to keep it from spilling out after added . the lid can be a snap on type or anything in the art . one skilled in the art of lids could easily design an appropriate lid . the bottom portion has a closure which can be opened or closed in a position in communication with the interior space such that it can deliver the solid to the interior space , in one embodiment by opening and delivering by gravity ( as shown in the figures ). in one embodiment , the means for opening and closing the closure is on either the compartment top portion or on the outer surface of the bottle . in one embodiment the closure is opened and closed by sliding and a slide mechanism such as a button to open and close the closure , for example , as shown in the figures . now referring to the figures , fig1 is a side view of the compartments of the present invention fitted in the cap of a bottle for a liquid . the bottle is removed in this view for clarity . bottle screw on cap 1 fits on the top of , in this embodiment , a water bottle by screwing or snapping on the bottle opening . the cap 1 also has water bottle drinking spout for opening and closing and taking a drink of water . in this view two of three compartments 5 a and 5 b for placing a solid to be placed in the bottle are shown . each compartment 5 a and 5 b have a removable lid 6 a and 6 b which when opened reveals an opening to add the solid . one can then add into each compartment enough of the solid one needs / wishes to add of which ever component is desired to add to the liquid . in one embodiment , each compartment contains a different solid and two or more solids are placed in the interior space at the same time . this is useful when combining ingredients which are not compatible long term with one another . on the side of compartments 5 a and 5 b are slide buttons 7 a and 7 b which are used to open the closures at the bottom of the compartments and deliver the solid to the interior space of a bottle . by sliding the buttons using slot 8 , one can slide open and closed the enclosure and such mechanism is within the skill in the art in view of this disclosure and drawings . fig2 is a bottom perspective view of the bottom of the compartments showing the closure for delivering the solid to the liquid in the bottle . the third compartment 5 c can be seen in this view . accordingly , since there are three compartments the user can deliver up to three doses of solid to the bottle . each of the compartments has a closure 9 a , 9 b and 9 c which are open , partially open and closed respectively in the drawings . when the slide buttons are slide in one direction it opens the closure the other direction closes the closure . since the closures are on the bottom of the compartment &# 39 ; s opening , the closure allows the contents of the compartment to fall by gravity into the interior space assuming the bottle is in the proper upright position . fig3 is a side view of the device in fig1 mounted on a bottle and delivering a solid powder to some liquid in the bottle . bottle 15 is shown mounted with the cap and compartments of fig1 . in this view a powder 16 can be seen in compartment 5 a and with slide 7 a in a position which opens the closure powder 16 a can be seen falling into liquid 17 in the bottle . the powder can then be mixed , for example , by shaking the bottle after the closure is closed insuring no liquid enters the compartment . when the user finishes the liquid , more liquid ( e . g . water ) can be added to the bottle and another dose of powder from another compartment added . while a water bottle is depicted in the drawings , any type of bottle can be utilized such as a baby bottle or the like . those skilled in the art to which the present invention pertains may make modifications resulting in other embodiments employing principles of the present invention without departing from its spirit or characteristics , particularly upon considering the foregoing teachings . accordingly , the described embodiments are to be considered in all respects only as illustrative , and not restrictive , and the scope of the present invention is , therefore , indicated by the appended claims rather than by the foregoing description or drawings . consequently , while the present invention has been described with reference to particular embodiments , modifications of structure , sequence , materials and the like apparent to those skilled in the art still fall within the scope of the invention as claimed by the applicant .
