Leclair Assistant ExaminerStephen Marcus AnorneyHarness, Dickey & Pierce ABSTRACT: The folder has two flaps extending outwardly from a back section disposed at right angles thereto. The back section permits assembly of papers within the folder without undue bulging and provides a support for an elastic band. The band is made from a strip of elastomeric material having its ends secured to a metal clip in T-relation thereto. The clip engages the inside of the back section when the band is drawn through an aperture therethrough to have the clip engage the inner face thereof. The extending band can be drawn over one end of the folder to secure the two flaps and the contents thereof in compact relation.
FOLDER WIT I-I ELASTIC BAND BACKGROUND OF THE INVENTION Reference may be had to the patent to Norman J. Humphrey, US. Pat. No. 2,917,224, issued on Dec. 15, 1959 for Paper and Coin Container to show a typical folder.
SUMMARY OF THE INVENTION The invention pertains to a folder made from heavy paper stock which is die cut, scored and folded to form pockets of various shapes known in the art to be suitable. The center of the sheet is double scored to form a back section from which flaps extend forwardly at right angles thereto in parallel relation to each other. The elastic band is made from a strip of elastomeric material having the ends abutted and secured to a clip which is disposed in substantial T-relationship to the loop portion thereof. The loop portion is threaded through an aperture in the back section from the inside thereof and drawn outwardly until the clip engages the inner face thereof to bridge the aperture. The elastic loop projecting from the back section is of a size to be drawn over one end of the folder to extend therearound for retaining the flaps and contents in compact relationship.
When the folds which form the pocket extend across the center of the sheet, score lines are provided at the center thereof in continuation of the score lines which form the back section. While the aperture may be punched in the back section and pocket fold during the die cutting and scoring of the sheet, the aperture may be punched in the back section and the pocket fold after being folded together. The double wall at the back section provides extra strength for retaining the clip on the inner face thereof.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The folder embodies a sheet of heavy paper stock or like material which is die cut and scored to have a pair of flaps l0 and 11 which extend outwardly from a back section 12 at substantially right angles thereto when the flaps are moved into adjacent relationship. In the example herein illustrated, the flaps l0 and II and back section 12 along with the pocket sections 13 and 14 are stamped from a sheet of heavy paper material and scored along the lines 15 and 16 to permit the flaps l0 and II to be folded relative to the back section 12. Score lines 17 and 18 are provided along the outer edge ofthe flaps 10 and 11 which permit securing flaps 19 to be bent inwardly against the flaps 10 and 11. A score line 21 is provided at the bottom edge of the flaps l0 and 11 at the juncture with the pocket sections 13 and 14 and also in the center along the lines 22 to permit the pocket sections 13 and 14 to be folded against the inner face of the flaps 10 and I1 and adherred by suitable material to the faces of the reversely bent flaps 19.
An aperture 23 is punched through the back section between the two flaps l0 and 11 and the two pocket sections 13 and 14 through which an elastomeric band 24 is threaded with a securing clip 25 drawn against the inner face of the pocket sections 13 and I4. The elastomeric band 24, as illustrated in FIG. 6, is made from a length 26 of elastomeric material having an elongatable woven cover 27 thereon. The two ends 28 of the band are placed together and secured within a metal channel clip 29 which is clinched thereabout. The clip is in substantially T-relationship to the loop portion 31 extending therefrom. When the loop portion 31 is drawn through the aperture 23, the clip 25 will bridge the aperture 23 and be drawn against the inner face of either the back section 12 or the like section between the pocket sections 13 and 14. The loop extends outwardly from the rear side of the back section 12, as illustrated in FIG. 3, and after the contents have been placed in the pockets 29 on the flaps I0 and II and moved into engagement with each other, the loop 31 is stretched thereover to retain the flaps l0 and 11 in substantially abutted relationship, as illustrated in FIG. I. This forms a compact unit which reduces the bulging of the flaps, the accidental separation thereof and the possible loss of the papers contained therein. It is to be understood that various types of pockets may be formed with the flaps l0 and 11 and that such pockets need not extend across the back section. When extending over the back section, the punching of the aperture through both sections provides added strength for retaining the clip 25 on the inner face of the section and prevents the enlargement or tearing of the aperture.
By employing the back section in the folder the aperture therethrough is spaced from the score line and provides maximum strength for holding the clip against the inner face thereof. If a single score line were provided between the flaps and the back section eliminated, the center of the aperture would fall upon the score line and the holding force thereof would be substantially weakened.
1. In a folder, a sheet of material die cut and scored to pro vide a pair of flaps extending from a back section which is disposed at right angle thereto when the flaps are folded into adjacent position, pocket means on the inside of said flaps, and an elastic band made from a length of elastomeric material having the ends provided with securing means to form a loop, said back section having an aperture through which the loop of the band is drawn to have the securing means abut the inner face of the back section.
2. In a folder as recited in claim 1, wherein the pocket means extends across the back section with an aperture therethrough aligned with the aperture in the back section to provide a double thickness of material at the apertures for holding the securing means.
3. In a folder as recited in claim 1, wherein a metal clip secures the adjacent ends of the elastomeric material together and is positioned relative thereto as to span the aperture in the back section when securing the loop in extended position from the rear face thereof.
4. In a folder as recited in claim 1, wherein the pocket means is formed from an extension of the flaps which is reversely folded into engagement therewith and secured at the outer ends to the outer ends of the flaps.
5. In a folder as recited in claim 4, wherein sections are folded inwardly from the outer edges of the flaps to which the outer edges of the pocket means are adherred.
