Patented Jan. 13, 1942 UNITED STATES PATENT OFFICE 2,269,525 oanBoNfrArEncoN'rAmER Nathan Fleischer, Brooklyn, IN. *iY. Application December 16, 1938, 'Ser ial No.'246,085 .4 Claims. (01. 206-57) "This invention relates toimprovements in containers for the packaging "of carbon paper sheets.

The primary object of the invention resides in a carbon paper box in which individual sheets of carbon paper are arranged in stacked formation thereimmay be removed therefrom without necessitating the reaching in andthumbing the sheets to facilitate individual grasping and withdrawal of the same, thus saving time .for the typist and reducing the likelihood'of thesoiling of the fingers of the "hand and wrinkling of the sheets during such withdrawal operation.

Another feature of the invention is to provide a .carbon sheet paper box bywhic'h' finger pressure applied .to' a predetermined portion of the cover thereof will cause the forward portion of the uppermost carbons'heet to be lifted from the pack of sheets, whereby an operator may by lifting of .the cover reach into the lboxand conveniently remove a carbon sheet therefrom.

A furtherffeature of the invention is the provision of a carbon sheet container having sheet pick-up means formed integral with the cover of the box, thus :keepingthe cost of inanuiacture of the box to a minimum.

Other features of the invention will be "apparent as the specification is read in conjunction with the accompanying drawing, in which:

Figure 1 is a perspective view of 'a carbon sheet container constructed in accordance with one form of my invention, the box being illustrated in its normal closed position.

Figure -2 is a perspective view showingthe carbon sheet container with the front cover section in raised position and with the pick up 'flap partially depressed.

Figure '8 is an enlarged vertical longitudinal sectionalview on theline '88 of Figure "7.

Referring to the drawing by reference "characters, and at present to'the form :of thein'vention shown in Figures 1 to 3 inclusive, the numeral l designates .my improved carbon sheet container in its entirety which includes a rectangular tray .like body .H which .edmpris'es flat bottom wall l2, :and upstanding side walls body '|.l with the dependingwflanges or sidewalls l6 of the cover snugly embracing the upstanding side walls il3 of the body. The cover [4 is divided by a transverse fold line I! into a rear cover section .Ifland a front-cover section 4 9,, the longitudinal side walls 1 6 of the cover being cut as arm in line with the fold line 11 whereby the front cover section I9 may be swung upwardly and pivot ontlie fold-line l1 whilethe rearcover section 18 remains .in'its normal position over the tray like body ll.

Thei front cover section I9 is provided with a U-shaped slit consisting .of spaced longitudinal slits 2i.2l and with .a connecting transverse slit -22 to provide a :depressible pick up .fiap 23. The .flap 2.3 is arranged along the longitudinal center of the cover and the free edge of .the flap 23 is disposed adjacent the front side wall J6 of the front cover section -.l9. I ,In ,forming the slits 2iand 22,, a break is provided in order to normally hold the flap "23011 the ,same plane as the top of the cover section 19, but which interruption in the slits does not interfere with the breaking of the iiap :23 free so as to move inwardly of the "cover .as illustrated .in Figures .2 and 3 of the drawing. 'Iheunclerside-of the flap 23 adjacent the front free edge thereof is pro-- vided with a spot .of'adhesive sub-stance 24 and which adhesive substance may be .of the .kind which remains tacky "although exposed 130 15116 atmosphere.

Also cut from the front cover section l9 and disposed forwardly of the transverse slit 22 is a pull tab 25, which isformed by providingvslits or weakened Iinesin the cover sectionilil whereby nonnall ythe zpull tab lies .in the same plane {as the top wall of the :coverbut which permits the pull tab 25 to ice pulled upwardly :as illustrated in Figure 3 of the drawing when the 'container is opened :for use.

"In'pradtice, the container 10 with the pack of carbon sheets A packaged therein is received by -the user'in'the form shown in'Figure "1 of "the drawing, and the ftypist in opening the container swingsthe-front cover section 19 upwardly on the fold line If! as "illustrated .in Figure and ,procoeds to break the flap ;23 "inwardly and the pull [3. A pack of carbon paper sheets A .s'nu'gly fit-' tab 25 outwardly. The container .is now .pre

pared for the individual removal of the carbon sheet A and when a sheet A is to be withdrawn from the container, the operator with the front cover section IS in closed position places a finger on the pick up flap 23, and lightly presses upon the flap, causing the flap to move inwardly and contact the upper side of the uppermost carbon sheet A, whereupon the adhesion substance 24 causes the carbon sheet A to adhere to the fiap 23, after which the operator grasps the pull tab 25 and swings the front cover section [9 upwardly, thus lifting the front end of the carbon sheet as best illustrated in Figure 3. It is now convenient for the operator to reach the front edge of the partially lifted carbon sheet and pull the same free of the adhesive substance 24 and withdraw the carbon sheet entirely from the tray like body I I. After each withdrawal of the sheet, the front cover section I9 is lowered to its closed position and the same procedure as above described takes place when the next uppermost sheet is to be withdrawn.

Whereas I have shown and described a cover divided into rear and front sections, I wish it to be understood that the cover may be of a single section, and the forward end lifted up with the rear end of the cover fulcruming on on the rear side Wall of the body without in any way departing from the spirit of the invention.

In Figure 4 of the drawing, I have illustrated a top plan view of a modified form of the invention, and in which the numeral 26 designates the cover of the container having a pick up flap 21 cut from the top wall thereof and which is identical with the flap 23 with the exception that the free end of the flap faces rearwardly instead of forwardly. The underside of the flap 23 is provided with a spot of adhesive 28 and a lifting pull tab 29 is cut from the flap 21.

In Figure of the drawing, the numeral 33 designates the cover which telescopically fits the tray like body II and which cover has slit or weakened lines 3| at the front and forward sides of the cover to permit of the breaking out of a front cover section 32 which may pivot on the transverse fold line 33. A finger slot 34 is provided along the front weakened line 3| to enable the finger of an operator to reach the front edge of the cover section 32 in order to tear the same on the weakened lines 3|. With the front cover section 32 torn free and pivoting on the fold line 33, the entire section 32 may drop'into the body II and rest upon the uppermost of the carbon sheets. The pivoted cover section 32 is provided with a spot of adhesive 35 adjacent its front edge and pressure applied to the top of the section 32 adjacent the front edge will cause the adhesive substance 35 to adhere to the uppermost carbon sheet. The front section .32 rearward of the spot of adhesive 35 is provided with a finger grip tab 36 which permits of the lifting of the cover section 32 after the uppermost carbon sheet becomes adhered to the adhesive spot 35.

In Figure 6 there is shown a further modified form wherein the cover 31 is scored transversely on the dotted line 38 to provide a front pivoted cover section 39. Cut from and disposed adjacent the front edge of the section 39 is a finger tab 40 by which the section may be swung upwardly. The cover section 39 rearward of the tab 40 is provided with an opening 4| and disposed beneath the opening 4| is the free end of a flexible tongue 42 constructed of cardboard or the like, the rear end of the tongue being fixed to the underside of the box by a staple 43. The free front end of the tongue 42 has a spot of adhesive 44 on the under side thereof. In practice, the operator inserts a finger through the opening 4| and depresses the front end of the tongue 42 so as to cause the adhesive spot 44 to contact the uppermost carbon sheet, whereupon lifting of the cover section 39 by grasping the tab will effect a lifting of the front end of the carbon sheet so that an operator may grasp the lifted portion of the carbon sheet and remove the same from the container.

In Figures 7 and 8 of the drawing, there is shown a still further modified form in which the numeral 45 designates the top cover of the container and which is formed with a transverse fold line 45 for dividing the cover into a hinged front cover section 41 and a rear cover section 48. Secured to the underside of the front cover section 41 by a metal staple 49 is a resilient spring tongue 50, th front free end of which is provided with a spot of adhesive 5| on the underside thereof. The tension of the tongue 50 causes the adhesive spot 5| to always contact the uppermost of the carbon sheet, thus eliminating the necessity of applying pressure to cause the pick up element to engage with the sheet to be removed. To facilitate lifting of the front cover section 41, the forward portion of the top thereof is provided with a punched out finger grip tab 52.

From the foregoing description, it will be seen that I have provided a carbon paper box in which the front portion of the uppermost sheet of a stack of carbon sheets may be picked up with the opening of the cover of the container, whereby a typist may conveniently reach in and grasp the lifted portion of the carbon sheet and withdraw the same from the container.

While I have shown and described what I consider to be the most practical embodiment of my invention, I wish it to be understood that other changes and modifications may be resorted to as come within the scope of the appended claims.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent of the United States, is:

l. A container for loose paper sheets comprising a box body adapted to contain a pack of paper sheets, a relatively stiff cardboard cover fitting over said body, a depressible hinge flap struck out from said cover, and an adhesive substance provided on the underside of said hinge flap whereby manual downward swinging movement of said fiap will cause said adhesive substance to contact the uppermost sheet of a pack of sheets for separation therefrom upon subsequent upward tilting of said cover.

2. A container for loose carbon paper sheets comprising a tray-like body adapted to contain a pack of carbon paper sheets, a relatively stiff cardboard cover fitting over said body, a depressible hinge flap struck out from the top wall of said cover adjacent the front end thereof, a spot of adhesive provided on the underside of said hinge flap whereby manual downward pressure applied to said hinge flap will cause the adhesive thereon to engage the uppermost sheet of .a .pack of carbon paper sheets and subsequent lifting of the front end ofsaid cover will cause the front portion of an uppermost carbon sheet to be lifted therewith for easy withdrawal from the tray-like body.

body to cause the adhesive to forcibly contact the uppermost of a pack of carbon paper sheets thereby causing the sheet to adhere thereto for subsequent removal therefrom upon the upward tilting of the front end of said cover.

4. A container for loose carbon paper sheets as set forth in claim 3, including a pull tab formed from the top wall of the cover by weal:- ening or slitting the top wall on two spaced lines extending from the U-shaped slit.
