Abstract

The invention refers to a device for an environmental and resource saving means of holding together brochure pages, office papers, sheets of paper and similar which can be furnished as complements to business cards, post cards, covering letters or stiffened paper (1) and pieces of cardboard. One or more cuts (2, 9, 10) in special directions and shapes are punched into the card with the aim of a corner of the sheet of paper (12) and brochures etc; being able to be introduced through the whole length of the cut and be folded together on the reverse side of the card. Thanks to the modified cut's special shape, the pages are firmly held together and oriented in all directions without the use of foreign materials such as metal and plastic paper clips, metal clips etc.

Description

DEVICE FOR HOLDING TOGETHER SHEETS OF PAPER

The present invention refers to a device intended to temporarily hold together office or other sheets of paper, prospectuses etc. in the simplest way

There are different products on the market for similar purposes For example the office paper clip in metal or plastic can be mentioned, sample bag clips or paper bindings of metal or plastic which are used for holed paper; paper gatherers in plastic for use with holεd paper, lockable clips or corner clips of plastic or stamped metal respectively, that are folded double together with one of the corners of a bunch of papers: staples of metal wire that are applied with a stapling machine etc. All of these products have in common that they involve a combination of different materials, which can be a problem, not least from a recycling point of view

From an environmental and resource utilisation point of view, it would be advantageous if several sheets of paper could be temporarily held together without using foreign materials such as metal, plastic, wood veneers etc. Such materials can also be unsuitable for mechanised letter openers and document destruction devices. For this reason one object of the invention is to achieve a device of the kind described in the introduction that does not require any material combination. Nevertheless separate material combinations are possible within the framework for the idea of the invention if this was considered to be necessary

It is therefore advantageous if, for example, business cards, post cards and covering letters etc., could, in the simplest manner and almost invisibly, be arranged so that they themselves formed the means of joining, for example, documents, brochures and price lists As a suggestion one side of a business card could be used for a good-will creating greeting message to the receiver of enclosed papers.

The present invention satisfies the stated aim in a very simple way A device in accordance with the invention is characterised by a piece of stiffened paper or card in the form of a business card, post card or similar having at least one sheet with a substantially penetrating slit or cut in one section at a predetermined angle in relation to the paper sheet's long or perpendicular edge. If this cut is designed in such a way that one or more tongues or flaps are created and project from an imaginary line that runs between the ends of the cut. a great K improved joining capacity can be achieved bv the device Tnese tongues or flaps thereby serve as holders so that the device and the joined office papers he flat and substantialK parallel m relation to each another The cut can be completely through the cardboard mateπal but it does not have to completely penetrate as long as it almost does, as the user should easily be able to open the cut using a shearing action before the device is used for joining brochure pages etc

The aim of the invention is achieved if a corner of the papers that are to be held together is threaded through the paper material (of thin cardboard or similar mateπal intended for business cards) that has been provided with a stamped cut of special shape and form These paper corners are then folded together on the other side of the cut card or stiffened paper If the cut has the special shape described here, none of the papers can loosen in anv direction, at least with any reasonable forces The tongues or flaps that have been formed bv the special shape of the cut have a holding function towards the plane, in the first hand of the front side of the sheets of paper If at least one tongue or flap is on the same side as the sheets of paper and thereby above them, then these sheets can not be loosened in the direction against the base of the tongue as the tongue and the ends of the cut themselves form hinders Sheets can only be loosened in the opposite direction with a certain amount of difficulty, due to the forces that strive to open or widen the folded corners of paper being directed substantially parallel with and thereby fairly close to the plane of the device and the line of the fold of the corners and additionally at a maximum angle to the direction of the papers' corners

In order to hold both the sheets of paper and their folded corners on the reverse of the device at least one tongue must be on each side of the device and thereby on the upper side of the surfaces of the sheets This can be achieved if a tongue is freed to one side by one or more cuts approximately perpendicular to the base of the tongue or the alignment line of the cut, through which a tongue, freed in such a way, can be forced over to the device's other side once the sheets of paper have been pushed through the cut and the corners folded together

The designs of the cut, which can easily by made with ordinary pπnting punches or knives, are shown below in different modifications with reference to the appended figures

Figure 1 shows a post card with a simple, straight cut according to the invention

Figure 2 shows a business card with a modified, shaped cut

Figure 3 shows how the ends of the cut are closed with a πp-stopping punch hole Figure 4 shows a modification of the cut in a round postcard

Figure 5 shows a hole-punched covering letter where the

cut has oeen supplemented with two cuts at an angle

Figure 6 shows how one or more sheets of paper are locked in a device according to the invention

Figure 7 shows how a business card folded double has been given a cut according to the mvention

Figure 8 shows a bundle of papers that have been loined in a business card folded double in accordance with the invention

Figure 9 shows how a number of office papers have been mounted in their upper short edge with a busmess card folded double

Figure 1 shows a conventional postcard of stiff paper, card or foil with a straight through cut 2 of the simplest type running from the end 3 to the end 4

Figure 2 illustrates a postcard, stiffened paper sheet or similar, made of relatively strong cardboard mateπal Close to one of the corners a substantially penetrating cut, 2, of a certain length has been punched at 45 degrees between two of the business card's edges The cut 2 goes from the end 3 to the end 4 and partly follows a straight alignment line, 5, between these two endpoints, and also along a parallel alignment line, 6, about 1 -3 mm from the alignment line 5 In this way a tongue or flap 7 is created that forms an effective holder tor office papers 12 etc, if the corners of these are threaded through and fill up the opened cut or cuts and are also folded along the cut on the reverse of the card

In figure 3, the cut 2 has been made barbed which has created two flaps 7 and has also been supplemented with a soft rounding or hole, 8, at the ends 3 and 4 which leads to the cut and the paper sheet being more resistant to external πppmg forces

In figure 4, the cut in a circle shaped stiffened paper 1 has been shaped in waves or spikes which creates several tongues, holders or flaps 7

Figure 5 shows how a larger hole-punched coveπng letter has been given two more straight or shaped cuts 9 and 10, which have been placed in two different angles to the alignment line 6 In this way a separate flap, 1 1, has been created in addition to the two flaps 7 that are formed between lines of sight 5 and 6 and the special shape of cut 2

In figure 6 it is shown how one or more sheets. 12, or papers have been threaded through the entire opening of cut 2 to both of its ends. These papers have then been folded on the reverse of the card. The cut follows, in the main, the shape of a large arc except at the ends where the cut is straight and coincides with the folding of the sheet 2 in order to suppoπ and shape it.

In figure 7, the device is shown as a business card folded double 1. On the front cover there is printing for a greeting in different languages with space for a signature or name. On its first inside page the company^'s or person's details is printed. On sheet two (pages three and four) the cut 2 is punched at 45 degrees close to one of the short edges up to the fold or crease line of the two pages.

Figure 8 shows a card folded double 1. in accordance with the invention, where a number of sheets of paper, 12, have been mounted by being inserted through the whole slit 2 and then folded back on the reverse side of the card or stiffened paper

Figure 9 shows another positioning of the cut 2 in a business card folded double 1 and how the office paper 12 is mounted so that the business card, 1, encloses the upper short edges of the pages 12, which can make an advantageous marker when inseπing into a folder or file.
