A storage container includes a container body, a closure, a releasable securement mechanism operable to latch the container body and closure together in a closed configuration and to unlatch them from one another into an opened configuration. Also, a multiplicity of spool segments are attached on the closure and spaced apart from one another so as to define a multiplicity of slots therebetween opening into an interior storage space at an interior side of the closure surrounded by the spool segments arranged in an endless row so as to form a multi-slotted spool. The flexible line is wrapped about the multi-slotted spool and its opposite end portions are inserted through selected ones of the slots into the interior storage space for stowing on the closure and within the storage container the flexible line and at least one attached device.
