Abstract
A looseleaf binder having a protective envelope that encases the front and rear flaps and spine of the binder such that the binder can be opened to view the interior of binder while protecting the binder cover from dust and other substances. The protective envelope is wrapped around the binder prior to attaching a ring binder unit to the cover, and joined to itself along the periphery of the binder. The ring binder unit is then attached to the interior of the spine through the envelope so the front and rear flaps foldably enclose the ring binder unit. The protective envelope may be removed from the binder without damaging or blemishing the binder.
Claims13
A looseleaf binder having a removable protective envelope, said looseleaf binder comprising:
- a spine;
- a front cover flap and a rear cover flap, each of said cover flaps being hingedly connected to said spine;
- a manually tearable protective envelope overlying substantially the entirety of each of said cover flaps as well as at least a portion of said spine, said envelope being readily removable from at least said flaps, without damaging either said flaps or said spine, upon tearing of said envelope;
- and
- a page binding structure fastened to said spine, said page binding structure overlying at least a portion of both said envelope and said spine;
- whereby, said front and back cover flaps may be freely pivoted with respect to said spine in order to open and close said looseleaf binder so as to permit substantially complete inspection and use of same at point of sale and elsewhere without necessity of removing said protective envelope.
A looseleaf binder having a removable protective envelope, said looseleaf binder comprising:
- a front cover flap and a back cover flap, each of said flaps having a respective inside and outside surface and peripheral edges bounding same;
- a spine hingedly connected to each of said flaps, said spine having an outer surface adjoining said outside surfaces of said flaps and an inner surface adjoining said inside surfaces of said flaps;
- a manually tearable protective envelope overlying substantially the entirety of said inside and outside surfaces of said flaps as well as at least said outer surface of said spine, said envelope covering at least said inside and outside surfaces of said flaps while being readily removable therefrom without damaging said flaps, by tearing said envelope;
- a page binding structure overlying at least a portion of said inner surface of said spine as well as any portion of said envelope which overlies said portion of said inner surface of said spine;
- and
- fastening means fastening said page binding structure to said spine;
- whereby, said front and back cover flaps may be freely pivoted with respect to said spine in order to open and close said looseleaf binder so as to permit substantially complete inspection thereof as well as operation of said page binding structure thereof without necessity of removing said protective envelope.
A method of making a looseleaf binder having a removable protective envelope, said method comprising the steps of:
- providing a front cover flap and a mutually opposable rear cover flap, each of said flaps being hingedly connected to a common spine;
- enveloping substantially the entirety of said flaps and spine in a manually tearable protective envelope, said envelope being readily removable from at least said flaps without damaging them, upon tearing of said envelope after said enveloping has been carried out, then
- fastening a page binding unit to said spine with said page binding unit overlying at least a portion of both said envelope and said spine.
