Abstract

A line reel for dispensing string, construction line, or cord includes a cap that can be inserted into one end of a spool holding the material to be dispensed, a midsection that can be inserted into the other end of the spool, and a rotatable handle connected to the midsection on the opposite side from the spool. In one embodiment, the cap and midsection frictionally engage the inside of the spool and can be pulled out of the spool for re-use with another spool. In an alternate embodiment, a latch structure on the cap and midsection latches the cap to the midsection in the spool so they cannot be easily removed from the spool once assembled. The line reel includes a notch to hold the free end of the construction line or string. The cap, spool, and midsection, while positioned structurally so that they do not rotate in relation to each other, are able to rotate in relation to the handle to facilitate dispensing the construction line.
