the preferred embodiment of the device for storing both clean and used baby bottle nipples is depicted in fig5 and 6 and comprises a cylindrical tubular member 10 having a first thread 40 near the open top end and a second thread 42 at the open bottom end . the cylindrical tubular member 10 is preferably of a transparent material to allow viewing of any baby bottle nipples and collars stored within the dispenser and is preferably approximately 5 inches in length with an approximate diameter of 2¾ inches . a flare at the bottom end of the cylindrical tubular member 10 adds approximately ⅛ inches the entire way around the perimeter such that the diameter is 3 ″ at the bottom end . a nipple - shaped top cap 18 has a first interior lip and a top retaining ring 34 tethered by attachment or integral formation of a thin flexible strip to an exterior surface of the top cap 18 . the interior of the retaining ring 34 a thread 38 for engaging the first thread 40 of cylindrical tubular member 10 to attach the top retaining ring 34 and thereby also attach the top cap 18 to the cylindrical tubular member 10 to prevent separation of the two and potential loss of top cap 18 . the exterior of the top retaining ring 34 includes a groove 24 for receiving the interior lip of the top cap 18 to removably connect said top cap 18 to said retaining ring 34 and thereby said cylindrical tubular member 10 . first interior lip is capable of engaging said groove 24 to close said first open end with said top cap 18 . nipple - shaped top cap 18 has a diameter corresponding to the top open end of the cylindrical tubular member 10 allowing for secure engagement of the two elements . a nipple - shaped divider insert has a shape conducive to allowing said insert to be slidably contained within said cylindrical tubular member 10 while segregating the interior of the cylindrical tubular member into clean and used portions for respectively receiving clean and used nipples and collars . in this way contamination which may be present on used nipples or collars in the cylindrical tubular member will not be spread to any clean nipples or collars . the shape and approximate height of 2¼ inches permits relatively close engagement with used nipples and collars on one side and clean nipples and collars on the other . a bottom cap 20 has a second interior lip and a bottom retaining ring 32 tethered to an exterior surface of said bottom cap 20 . the interior of the retaining ring 32 has a second internal thread 36 for engaging the second thread 42 of cylindrical tubular member 10 to attach the bottom retaining ring 32 and thereby the bottom cap 20 to the cylindrical tubular member 10 to prevent loss . the exterior of the bottom retaining ring 32 also includes a groove 26 for receiving the interior lip of the top cap 18 to removably connect said bottom cap 20 to said cylindrical tubular member 10 . bottom cap 20 has a diameter corresponding to the flare at the bottom open end of the cylindrical tubular member 10 allowing for secure engagement of the two elements . tabs 28 and 30 are provided on the top 18 and bottom 20 caps to act as levers for facilitating removal of the nipple - shaped top 18 and bottom 20 caps from engagement with said cylindrical tubular member 10 . another feature of this preferred embodiment is perforations 44 formed in top cap 18 to allow for communication of air inside the cylindrical tubular member 10 with outside air . in still further embodiments , perforations may be provided in the cylindrical tubular member 10 or the bottom cap 20 . as depicted in fig1 - 4 , an alternative embodiment of a device for storing used and dispensing clean baby bottle nipples comprises a cylindrical tubular member 10 having a groove 24 at its open top end and a second groove 26 at its open bottom end distal from said top end . the cylindrical tubular member 10 is preferably of a transparent material to allow viewing of any baby bottle nipples and collars stored within the dispenser and is preferably approximately 5 inches in length with an approximate diameter of 2¾ inches . a flare at the bottom end of the cylindrical tubular member 10 adds approximately ⅛ inches the entire way und the perimeter such that the diameter is 3 ″ at the bottom end . a nipple - shaped top cap 18 has a first lip for engaging the first groove 24 of the cylindrical tubular member 10 to assemble said top cap 18 to the cylindrical tubular member 10 to close its open top end . nipple - shaped top cap 18 has a diameter corresponding to the top open end of the cylindrical tubular member 10 allowing for secure engagement of the two elements . nipple - shaped top cap 18 has an interior diameter corresponding to the top open end of the cylindrical tubular member 10 allowing for secure engagement of the two elements . a nipple - shaped divider insert is of a size and shape conducive to allowing said insert to be slidably contained within said cylindrical tubular member 10 . nipple - shaped divider insert has a diameter slightly less than that of the cylindrical tubular member to allow for unrestricted sliding of the divider insert therein . the shape and approximate height of 2¼ inches permits relatively close engagement with used nipples and collars on one side and clean nipples and collars on the other . a bottom cap 20 has a second lip for engaging the second groove 26 of the cylindrical tubular member 10 to assemble the bottom cap 20 to cylindrical tubular member 10 to close its open bottom end . bottom cap 20 has a diameter corresponding to the flare at the bottom open end of the cylindrical tubular member 10 allowing for secure engagement of the two elements . retaining ring 22 is tethered to the bottom cap 20 and when slid over the cylindrical tubular member 10 at the top end holds bottom cap 20 to cylindrical tubular member 10 to prevent separation of the two and potential loss of bottom cap 20 . retaining ring 22 is prevented from slipping off of cylindrical tubular member 10 by the top cap 18 at the top end and by a flare 21 at the bottom end . tab 28 is formed on an edge of said bottom cap 20 and capable of acting as a lever for facilitating removal of said bottom cap 20 from engagement with said cylindrical tubular member 10 . a second tab 30 is also formed on an edge of said top cap 18 and capable of acting as a lever for facilitating removal of said top cap 18 from engagement with said cylindrical tubular member 10 . a user removes the used nipple and collar from a feeding bottle ( not shown ), opens the dispenser by removing the bottom cap 20 which remains tethered to the cylindrical tubular member by way of the bottom retaining ring . after placing the used nipple cap 14 into the tubular cylindrical member through the bottom opening , the user replaces the bottom cap by snapping the interior lip of the bottom cap into the groove of bottom retaining ring 32 . the dispenser is thereby closed at its bottom end and the used nipple and collar 14 is separated from clean nipples and collars 12 by nipple - shaped insert 16 . the user may now open top end of the cylindrical tubular member 10 by removing the top cap 18 which remains tethered to the cylindrical tubular member 10 by way of the top retaining ring 34 . it is now possible to remove a clean nipple and collar 12 from the cylindrical tubular member 10 and subsequently replace the top cap 18 by snapping engagement of interior lip of the top cap 18 into the groove of the top retaining ring 34 . the clean nipple and collar 12 may now be placed onto the feeding bottle and the infant or toddler may be safely fed . the dispenser is capable of being stowed in a bag or backpack while occupying approximately the same amount of space as a feeding bottle . preferably , all of the components of the storage dispenser would be made of high grade plastic and would be formed via a press that would mold each component separately . components would subsequently be assembled by machine or by hand . it may be desirable to offer gender - preferred transparent colors of cylindrical tubular member . while the invention has been described with respect to certain specific embodiments , it will be appreciated that many modifications and changes may be made by those skilled in the art without departing from the spirit of the invention . it is intended , therefore , by the appended claims to cover all such modifications and changes as fall within the true spirit and scope of the invention .
a portable compact baby bottle nipple and collar storage and dispenser case includes a cylindrical tubular member , a top cap , a bottom cap and a nipple - shaped insert . the bottom cap is tethered to a retaining ring for preventing separation of the bottom cap and the cylindrical tubular member . the nipple - shaped insert separates any clean nipples and collars held by the dispenser from any dirty nipples and collars held by the dispenser .
