发明名称 Leaf retaining means
摘要 Leaf retaining means for loosely retaining a multiplicity of leaves of material, such as sheets of paper. The leaf retaining means comprise a base portion, which is provided with at least one formation to enable it to be secured to a folder cover, and loop means, the latter has at least two points on its surface which two points are closest to an imaginary plane which does not pass through that position and which is perpendicular to the loop means, and which two points are spaced apart. The loop means are such as to enable a leaf of material, such as a sheet of paper, with a generally T-shaped aperture in it that is open at an edge of the leaf, to be releasably held by the loop means by pushing the aperture onto the loop means.
