Description:
THE INVENTION 
     This invention relates to a multileaf back loading and back unloading binder for menus, photos, cards and the like providing a series of transparent interconnected pockets between the front and rear covers which provide ready access only from the rear of the binder thereby avoiding damage to the articles by frequent handling. 
     BACKGROUND AND HISTORICAL DEVELOPMENT 
     Binders and albums of transparent nature for holding menus, photos, cards and the like has been used for well over a hundred and fifty years. Arms U.S. Pat. No. 164,249 is an early 1875 patent showing the series of interconnected pockets. The loading is from the side as is Holson U.S. Pat. No. 4,267,655. 
     Schorrig U.S. Pat. No. 5,135,401 does provide an album with pockets but the loading is from the front or sides. 
     Forbes U.S. Pat. No. 683,853 provides and album which may be loaded and unloaded from the sides. 
     Pepys U.S. Pat. No. 6,061,943 shows an album which is loaded from near the back but the front and rear panels of each pocket are of different length so that loading multiple items must be done by flipping one pocket after the other. 
     Candido U.S. Pat. No. 5,323,553 in affect presents the same problem of loading as does Pepys when you have multiple leaves. 
     Cornish U.S. Pat. No. 1,988,998 provides for side loading and the binder is stitched up so that it would be impossible to load and unload from the rear. 
     OBJECTS AND SUMMARY 
     It is an object of this invention to provide a binder, album or portfolio or the like in which the articles to be mounted or removed from therein may be readily inserted or removed from the rear without having to page or flip one pocket after another. 
     Another object of this invention is to provide a back loading and unloading binder for menus, photos, cards and the like which protects the article from side, front and rear subsequent to mounting of the articles. 
     Still a further object of this invention is to provide a multileaf back loading and back unloading binder which can be made from a single long sheet of transparent material. 
     Another object of this invention is to provide a multileaf back loading and back unloading binder which is inexpensive to manufacture and which can be viewed from both sides of the pocket in which an article is placed. 
     A further object of this invention is to provide a multileaf back loading and back unloading binder which has a readily removable and replaceable backing for easy access to the pockets from the rear and provides protection after the articles have been loaded. 
     Still another object of this invention is to provide a multileaf back loading and back unloading binder which is light weight and easily handled. 
    
    
     
       In summary, this invention relates to a multileaf back loading and back unloading binder for menus, photos, cards and the like which reduces wear and tear on the articles inserted in the pockets as well as wear and tear on the binder itself. These and other objects will be apparent from the following description and the accompanying drawings which are as follows: 
         FIG. 1  is a perspective view of the binder showing the transparent cover in open position; 
         FIG. 2  is a perspective view showing the binder with the backing opened up to permit the article to be inserted into a pocket from the rear;

     DETAILED DESCRIPTION OF THE INVENTION 
     
       FIGS. 1-6 
     
     In  FIG. 1 , the binder B is shown with the front cover C in raised position over the pockets P. The backing strip A is attached to the front cover C and the back cover R and circumscribes the back of the pockets P. Cover R is not secured or sealed to the back of the pockets P. The front and back covers C and R may be transparent, translucent or opaque. The front and back covers C and R may be relatively stiff material so as to avoid crimping or creasing. In  FIG. 2 , the backing strip A is shown removed from the front cover C while attached to the back cover R so as to expose the rear of a pocket P for insertion of an article X such as a menu, photo, card to the like. 
     As best shown in  FIG. 3 , the backing strip A comprises a base member  2  having spaced pressure sensitive adhesive  4  along its sides. Peel-off strips  6  are provided to protect the adhesive  4  prior to positioning the backing strip A. Strip A includes a non-adhesive central portion  8 . When the backing strip A is applied to the front and rear back covers C and R, the pressure sensitive adhesive  4  maintains the backing strip A in position so that the central portion  8  covers but does not engage the pockets P. The pressure sensitive adhesive  4  is of the type that it will release from the front or back covers C and R for insertion of an article X and can be easily repositioned and secured to either the front or back covers C and R subsequent to insertion or removal of an article X. Other types of backing strips may be used such as Velcro applied to the covers and strips or tongue and groove devices which snap on but release by lifting or zipping. 
     As best shown in  FIG. 6 , the pockets P comprise front and rear panels  10  and  12 . Hinge strips  14  are provided between successive pockets P. Hinge strips  16  seal front panels  10  to rear panels  12  at the top of the pockets P. Hinge strips  14  connect the pockets P at the bottom of the pockets P. The sides of the panels  10  and  12  are secured together by hinge strips  18 . 
     The hinge strips  14 ,  16  and  18  are secured to the panels  10  and  12  by permanent adhesive not of the pressure sensitive removable type as on the backing strip A. 
     
       FIG. 7 
     
     In  FIG. 7 , the binder B comprises a series of transparent interconnected pockets P having heat sealed side edges  22  and heat formed top hinges  24 . Pocket heat formed hinges  26  connect the pockets P. Front and back covers C and R are integral with the pockets and are provided with heat formed hinges  28  and  30 . Thus a single sheet of material can be used to form the covers C and R as well as the pockets P.
