This inventionrelates to fasteners for expandable stationery folders and more particularly to the ribbon or tying element.

Expandable stationery folders or files are usually formed as an enlarged envelop with the open end having an enclosing flap. Envelops of this type are neces sarily provided with a string, ribbon or flexible strap to wrap around or partially around the envelop to hold the flap tightly closed. This string ribbon or flexible strap may be tied or may be fitted to a holding clasp. This invention is primarily concerned with a particular type of elastic ribbon and a particular means of easily removing the old ribbon and easily inserting a new ribbon.

It is an object of this invention to provide a stationery folder in combination with a fastening element andelastic ribbon in which the elastic ribbon is provided with means at either end of said ribbon that are easily anchored into removed from said envelop to remove said elastic ribbon.

A still further object of this invention is to provide a renewable elastic ribbon for a stationery folder in which the elastic ribbon is provided with a pair of metal clips at either end thereof and in which the folder is provided with an aperture into which the metal clip of one end may be inserted to retain the elastic ribbon and permit tying or fastening the ribbon to hold said folder closed.

Referring first to the preferred form of this invention illustrated in Figs. 1 through 6 there is illustrated a stationery folder or envelop 10 having one end open and provided with an enclosing flap 12. A flat elastic ribbon 14 of suflicient length to wrap around folder it) is provided as a separate article as illustrated in Fig. 3. Ribbon 14 is provided with a metal clip 13 at either end thereof. The metal clip 13 may be simply a short length of metal slightly in excess of the width of the ribbon as shown Fig. 3 and in which the metal is formed as envelop 19 is provided with an aperture 17 at a predetermined position adjacent to the bottom edge 16 of the folder. The aperture 17 is in the form of a narrow slit large enough to permit forcing the metal clip 13 through the aperture while positioned in an endwise relationship. The slit or aperture 17 may thus be slightly enlarged at one end as shown in Fig. 4. After the clip 1.3 has been passed through the aperture 17 it is then pulled so that clip 13 will lie in a parallel relationship to the slit 17. And since the clip 13 is larger in width than slit 17 it will be anchored within the envelop 10 and will provide sufiicient anchorage to permit the ribbon 1 to be pulled upward as illustrated in Fig. 2 for a tying or fastening operation. The ribbon 14 may be affixed at its opposite end by means of a fastening element 13 such as that illustrated in the prior application mentioned above. Element 18 is affixed adjacent to the upper 20 of the folder. Element 18 is provided with a slot 21 spaced slightly below the edge 20. Slot 21 is cut or formed and the edges of slot 21 are spaced apart sufficiently to permit ribbon 14 to be fitted therein when ribbon 14 is stretched. Slot 21 may be formed with a wavy contour so that when ribbon 14 is released it will tend to bunch against the edge of slot 21 to thus be retained in its stretched position. It is apparent that ribbon 14- may be quickly and easily inserted into a folder such as folder 117 in which a slot 17 is prepared. It is also apparent that ribbon 14 may be easily removed by turning the clip 13 at right angles to the slit 17 and pushing the clip 13 outward. Thus a worn out ribbon 14 can be quickly and easily replaced. it is to be noted that when a ribbon 14 has been inserted through slit 17 the pull on the ribbon in fastening the ribbon about the envelop is not a pull directly outward but is a pull at right angles to the slit 17 thus tending to force the element 13 into a parallel abutting relationship with the inside of the envelop and providing considerable strength. Although element 13 is shown in a rounded form, element 13 in being formed or clipped to ribbon 14 may be provided in a square or other squeezed form without departing from the spirit of this invention. Although ribbon 14 has been described as an elastic ribbon this invention shall include a flexible ribbon 1 2- with little or no elasticity. However in such instance ribbon 14 must be of such a gauge or thickness that it will fit into slot 21 of the fastener element 18. In this instance due to the wavy contour of slot 21 there will be a gripping action on the flexible ribbon as the pull of the ribbon is not even and there is a tendency for the ribbon to bunch along the irregular projections of the wavy contour of the slot 21. The ribbon does not pull into the end of the slot. The ribbon will remain in the position in which it is inserted. Although envelop 11 has been described as provided with a single ribbon l4 afiixed thereto it is apparent that a plurality of ribbons 14 may be similarly used as illustrated in Fig. 4 without departing from the spirit of this invention. Figure 4 illustrates a partial section of the envelope showing the ribbon 14 after it has been inserted into the aperture 17, that is, the end of ribbon 14 provided with the clip 13. It is to be noted that the ribbon 14 may be inserted through aperture 17 by passing the ribbon from inside the folder through slot 17 and pulling the ribbon until the clip 13 abuts with the inner surface of envelope 10. However a simplified form of mounting ribbon 14 is Figure 4, in which the ribbon and clip are identical but in this instance the aperture 17 which is slightly enlarged at one end is used. This permits inserting clip 13 from the exterior of the envelope by forcing the end of clip 13 through the enlarged opening and sliding the clip into the position as illustrated and pulling ribbon 14 until clip 13 abuts with the inner surface of the envelope.

Referring to Figs. 7, 8 and 9 there is illustrated a further embodiment of this invention in which a cord is provided and in which a pair of clips 13A are to either end of the cord 14A in Fig. 7. Or a still further modification is illustrated in Fig. 8 in which the cord 14A 'is provided with a single clip 13A at one end thereof. In either modification the cord may be affixed to an envelop as illustrated in Fig. 9 in which the elem nt 13A is inserted within a slit 17A as described in the above embodiment and the cord 14A may be wrapped around the envelop to be fastened as described in the above embodiment or to be tied to a clip or fastening element as desired. Although the envelop has been described as fastened with a single cord affixed thereto it is apparent that a plurality of cords 14A may be similarly used according to the embodiment above illustrated in Fig. 4. In this embodiment cord MA may be an elastic cord or may have little or no elasticity without departing from the spirit of this invention. Although this invention and primarily the tying element 14 has been described as associated with an envelop 10 it is apparent that the invention as described may be practiced in connection with any package whether it be a complete folder or whether it simply constitutes a pair of sides such as the face 15, Fig. 1 and the opposite face as illustrated in Fig. 2 with any dimensions between these faces as long as element 14 is similarly used to be wrapped around the package and fastened in the same fashion as illustrated in the drawings. It is also apparent that one or more of the ribbons 14 or cords 14A may be afiixed to a package in the same fashion as that described herein to provide the fastening or tying means for the package without departing from the spirit of the invention and this invention shall be limited only by the appended claim.

What is claimed is:

The combination of a stationery folder, a bonding element and a fastening element aifixed to said folder in which said bonding element is provided with a metal clip at one end thereof and said folder is provided with an aperture to receive said bonding element, and said fastening element is formed of a rigid material and is provided with a slot that is open to one side of said element to receive said bonding element, said metal clip inserted through one end of said aperture to in turn position said bonding element in said aperture, and be retained in said folder and means to secure said bonding element with said fastening element.
