Abstract
Abstract A reel storage container comprising a body including a central post having a generally mushroom-shaped head; a cover having an elongate handle extending diagonally across its center; and a latching member mounted within the handle for longitudinal sliding movement between a release position and a latching position to which it is biased. The latching member will engage the mushroom-shaped head in its latching position, will cam around and engage the mushroom-shaped head when the body and cover are assembled, and is manually engageable through an opening in the handle so that the latching member can be manually moved to its release position to open the container.

Claim 1
Independent Claim
344 words
In a reel storage container comprising a body and a cover defining a chamber adapted to receive a reel, said cover having a generally planar top surface, a central recess from said top surface, and walls defining an elongate handle extending across said recess, said handle having said surfaces generally normal to said top surface adapted for manual engagement from the outer surface of said cover, and having a channel along its surface adjacent said body and an opening into said channel adjacent one end; a centrally located latch assembly for releasing coupling the body and cover together, said latch assembly including a central post fixed on said body and projecting into the channel in said handle when said body and cover are assembled which post has a generally mushroom-shaped head at its end, and a latching member mounted on said cover within said channel for movement between latching and release positions having a projection adapted to engage under said mushroom-shaped head when said latching member is in said latching position and the body and cover are assembled, a cam surface on said projection adapted to engage the end surface of said mushroom-shaped head and move said latching member toward its release position when said projection is moved past said mushroom-shaped head as said body and cover are assembled, and a contact surface positioned for manual engagement through said opening to move said latching member to said release position; and a spring integrally molded with said latch assembly for biasing said latching member toward said engaging position, the improvement wherein: said latching member is slidably mounted within said channel between said latching and release positions in a position recessed from said top surface; said spring is formed at the end of said latching member opposite said contact surface and bears against said cover; and said contact surface positioned for manual engagement through said opening to move said latching member to said release position is disposed generally transverse of the side surfaces of said handle and generally normal to the top surface of said cover.
