Combined document binder and cover holder

A document binder comprising:

• an elongated, unitary, generally channel-shaped body formed of an elastically resilient material, said body including two strip members extending generally parallel to one another, and a spine joining said strip members together lengthwise along a first side of said body to form the closed side of a generally U-shaped channel, said strip members extending adjacent to one another along a second side of said body to form an elongated, narrow binder opening along the open side of said generally U-shaped channel such that sheet material inserted into said binder opening is gripped and held between said strip members within said binder opening to bind together multiple sheets of the sheet material, said unitary body also including first and second branch members formed on said body extending lengthwise along the outside of said generally U-shaped channel overlying said strip members, said first branch member being attached to one said strip member lengthwise adjacent said binder opening, said first branch member extending toward said spine in a direction generally parallel to said one strip member and terminating near said spine to form a first elongate, narrow cover opening adjacent said spine which opens in a direction opposite to said binder opening and said second branch member being attached to the other of said strip members lengthwise adjacent said binder opening and extending toward said spine in a direction generally parallel to said other strip member and terminating near said spine to form a second elongate, narrow cover opening adjacent said spine which opens in a direction opposite to said binder opening, whereby said first and second cover openings grip and hold cover sheets which are folded over the document binder and sheet material.
