Abstract

Abstract An enclosure for a pad of notepaper including a rectangular elongate sheet of stiff paper material bent at scores to define along the length of the sheet an upper front portion adapted to overlie a part of the front surface of the pad, top, rear and bottom portions adapted to respectively overlie the top rear and bottom surfaces of the pad, and a lower front structure adapted to overlie a minor part of the front surface of the pad and having a recess adapted to frictionally and removably receive an end part of the upper front portion to close the enclosure.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 309 words
An enclosure for a pad of notepaper having front, rear, top and bottom surfaces, said enclosure comprising a rectangular elongate sheet of stiff paper material, said paper material having spaced transverse scores and being bent at said scores to define sequentially along the length of said sheet an upper front portion having a distal end part and being adapted to overlie a major part of the front surface of the pad, a top portion adapted to overlie and to be coextensive with the top surface of the pad, a rear portion adapted to overlie and be coextensive with the rear surface of the pad, a bottom portion adapted to overlie and be coextensive with the bottom surface of the pad, a lower face portion, a foldback portion and a guide portion, said foldback portion being parallel to and along the surface of said face portion adapted to be adjacent the pad and said guide portion extending parallel to and along and past the surface of said foldback portion opposite said face portion with said face, foldback and guide portions being attached together adjacent the proximal end of said guide portion while not being attached to said rear portion to provide a bottom front structure adapted to overlie a minor part of the front surface of the pad and to define a recess between said guide and foldback portions adapted to frictionally and removably receive the distal end part of said upper front portion with said engaged upper front portion and bottom front structure overlying and being coextensive with the front surface of the pad, with both the upper front portion and the lower front structure being pivotable away from the front of the pad upon removal of the distal end part of said upper front portion from said recess to afford access to the entire front of the pad.
Claim 2
Dependent Claim 309 words
An enclosure for a pad of notepaper having front, rear, top and bottom surfaces, said enclosure comprising a rectangular elongate sheet of stiff paper material, said paper material having spaced transverse scores and being bent at said scores to define sequentially along the length of said sheet an upper front portion having a distal end part and being adapted to overlie a major part of the front surface of the pad, a top portion adapted to overlie and to be coextensive with the top surface of the pad, a rear portion adapted to overlie and be coextensive with the rear surface of the pad, a bottom portion adapted to overlie and be coextensive with the bottom surface of the pad, a lower face portion, a foldback portion and a guide portion, said foldback portion being parallel to and along the surface of said face portion adapted to be adjacent the pad and said guide portion extending parallel to and along and past the surface of said foldback portion opposite said face portion with said face, foldback and guide portions being attached together adjacent the proximal end of said guide portion while not being attached to said rear portion to provide a bottom front structure adapted to overlie a minor part of the front surface of the pad and to define a recess between said guide and foldback portions adapted to frictionally and removably receive the distal end part of said upper front portion with said engaged upper front portion and bottom front structure overlying and being coextensive with the front surface of the pad, with both the upper front portion and the lower front structure being pivotable away from the front of the pad upon removal of the distal end part of said upper front portion from said recess to afford access to the entire front of the pad.
