Abstract

A binding folder has a spine with two hinged covers and with a pocket (16) near each end. A piece of material (20) is secured to the inside of the spine by tucking its folded back end parts into those pockets. The central part of that piece of material is slit to form a plurality of elongate longitudinal strips (28), each able to receive and hold brochures. <IMAGE>

Description

SPECIFICATION Binding folder This invention relates to a binding folder particularly intended for use in holding so-called part works, magazines, brochures and the like.

In our patent specification No. 1326082 we describe and claim a binding folder having two covers hingedly secured to a spine and a piece of material extending along the spine at the inside of the folder and secured at both end portions to the spine, the piece of material having a plurality of longitudinal slits dividing it into a plurality of elongate longitudinal strips. Methods suggested for securing the piece of material to the spine include welding and adhesive.

The need has arisen for a binding folder which will be of cheaper construction than the folder described in the aforementioned patent specification and yet will provide an adequate cover for the material held therein.

According to the present invention a binding folder comprises two covers and a spine round which the covers can hinge, a pocket near each end of the spine, and a piece of material having a central part which is substantially equivalent in length to the distance between the pockets and two end parts folded back from the central part, so that by tucking these end parts into the pockets the material is secured to the spine, the piece of material having a plurality of longitudinal slits running along the central part and dividing it into a plurality of elongate longitudinal strips.

The covers and the back of the spine may comprise a single sheet of plastics material, the spine having a further web of plastics material welded or otherwise secured along its edges to the said sheet, thereby providing the aforesaid pockets.

A particular embodiment of the invention will now be described with reference to the accompanying drawing, in which: Figure 1 shows a view of a spine part of a folder; and Figure 2 is a perspective view of the piece of material which fits thereto.

The folder is intended for use in holding so-called part works which are magazines issued in instalments, the complete series of magazines forming a reference book, or as a means of retaining brochures or the like. The folder is required to have some means for retaining the magazines or brochures and to protect the magazines or brochures.

The binding folder partially illustrated in the accompanying drawing includes a sheet of PVC plastics material 10 of a size to include both covers and the back of the spine. Secured to the sheet 10 by two lines of high frequency welding 14 is a web 12 of the same PVC material which runs centrally from top to bottom of the sheet 10 but stops short both of the top and bottom edges so as to form two pockets 16 between the weld lines 14.

A separate piece of material 20 shown in Figure 2 is made from a polyester plastics material, such as "Melinex"; it is formed with two permanent creases 22 round which the end parts 24 are bent back as shown in the drawing. The central part between the creases 22 is substantially the same length as the distance between the pockets 16 and over this length of the material it is punched to form a plurality of longitudinal slits 26 dividing it into longitudinal strips 28.

In order to complete the binding folder, the end parts 24 of the piece of material 20 are tucked into the two pockets 16 and are thereby secured to the spine thereby providing a satisfactory and reasonably inexpensive folder. Magazines and the like can be held by opening each magazine centrally and passing one half of the pages behind one of the strips 28 which is not at that time holding a magazine. The double thickness of PVC material constituted by the strip 12 and the sheet 10, reinforced by the end parts 24 of the piece of material 20, when these are placed in the pockets 16, form a spine round which the sheet 10 can be bent to form a cover. The edge of the cover may be finished off by a weld 30 to secure the edge of the bindersatisfac- torily.

It will be appreciated that many modifications can be made to the binding folder described above without departing from the scope of the invention as defined in the appended claims. Thus, for example, plastics materials other than polyester may be employed for making the separate piece of slit material 20, having the requisite physical characteristics of being able to be permanently creased and of sufficient rigidity for the end parts 24to remain bent back (as described) in use of the folder.And, for exampie, the pockets need not be formed by a web 12 of material running from top to bottom of the sheet 10 but stopping short of the top and bottom edges; they could just as well be formed from a web that runs from top to bottom of the sheet 10 without stopping short of the top and bottom edges but instead has transverse slits to form openings constituting the pockets; conversely the pockets could be formed by transverse bands extending across the spine end of which the edges near the top and bottom edges of the sheet 10 form openings constituting the pockets.

1. A binding folder comprising two covers and a spine round which the covers can hinge, a pocket near each end of the spine, and a piece of material having a central part which is substantially equivalent in length to the distance between the pockets and two end parts folded back from the central part, so that by tucking these end parts into the pockets the material is secured to the spine, the piece of material having a plurality of longitudinal slits running along the central part and dividing it into a plurality of elongate longitudinal strips.

2. A folder according to claim 1 wherein the covers and the back of the spine comprise a single sheet of plastics material, the spine having a further web of plastics material welded or otherwise secured along its edges to the said sheet, thereby providing the aforesaid pockets.
