DESCRIPTION:
BRIEF SUMMARY
BACKGROUND
This invention relates to folded sheet means.
Folded sheet means are known from the present inventor's previous PCT patent specification WO87/04284 which have the advantages and operate in the manner indicated therein. As exemplified therein, a sheet of paper or like material is folded with a first set of concertina folds and, when so folded, is folded with a further set of two concertina folds transverse to the first set. The sheet is provided, at two diagonally opposite coners, with a stiff portion of plastics material having the shape and size of a credit card. These portions lie outside the sheet when folded and enable it to be opened completely, very readily and in many cases with only one hand, and closed (refolded) almost as easily.
There is a demand for a method of providing a large quantity of information in a small space, reliably secure against being easily lost or mislaid. To fulfil such needs, there have been proposed attachments for key-rings, e.g. with a rolled up sheet of paper enclosed in a small cylinder with a screw cap and having one end provided with a suitable connection for a key-ring. Such attachments do not give ready and speedy access to the information and, further, the quantity of information is severely limited because of the bulk of the cylinder.
THE INVENTION
The present inventor has realised that the said demand can be coupled with a folded sheet, e.g. that mentioned in his aforesaid previous patent specification. The invention consists in folded sheet means as claimed in claim 1. There can also be provided the features of claims 2 to 22. Examples are: use in the pocket and use on a drawing board.
List of Features
Attention is drawn to the following list of features, though they are not to be regarded as necessarily important features or all of the important features of this disclosure.
1. Sheet material means comprising an envelope or like container and sheet material to be contained therein, characterized in that the sheet material has a first set of concertina folds and transverse to these a second set of folds and fits inside the container to be retained therein with the aid of friction or the like.
2. Means comprising an envelope or like container and sheet material to be contained therein, characterized in that the sheet material has a first set of concertina folds and transverse to these a second set of folds and fits inside the container to be retained therein with the aid of friction and/or at least one mechanical retaining portion of the container and/or springiness of the sheet when folded up due to its mutually transverse sets of folds.
3. Means comprising an open-ended envelope or like container and sheet material to be contained therein, characterized in that the container is open at least at one end and the sheet material has a first set of concertina folds and transverse to these a second set of folds and fits closely inside the container to be retained therein with the aid of the springiness of the sheet when folded up due to its mutually transverse sets of folds.
4. The second set of folds consists of a single fold.
5. The second set of folds consists of a set of concertina folds.
6. The first set of folds comprises an odd number of folds and the second set of folds comprises an even number of folds.
7. The container has a cut-out shape at its open end to facilitate grasping and withdrawing from it the folded sheet.
8. The container has at least one inwardly directed lip to facilitate retaining the folded sheet therein.
9. The container has the form of two sheets welded or otherwise fastened together peripherally.
10. The container comprises two sheet-like portions hinged together and releasably fastened together by said at least one mechanical retaining portion to aid in retaining the folded sheet material in said container.
11. Said at least one mechanical retaining portion comprises at least two press-stud means spaced apart along an edge of the container opposite the hinge.
12. The folded sheet material has a first set of concertina fo
