DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to folded sheet means. It is known to affix information to articles by means of labels. There is an ongoing desire to increase the amount of information that can be provided and at the same time reduce the space available for this and labels have been designed in the form of a long, concertina-folded strip under a cover which seals the strip to the article until opened. However, this is not user-friendly because of the awkwardness of the handling of it and because of the awkward shape which confines the presentation of information.
THE INVENTION
The present inventor has appreciated that these difficulties can be solved by taking a sheet which has substantial breadth as well as length and folding it with a first set of concertina folds and, so as to be transverse to these when the sheet is folded with these folds, a second set of concertina folds. The use of sheet means comprising such a sheet and also sealing means to seal the same in a folded condition and defined opening means at which the sealing means can be opened may have wider application than simply attachment to an article. For example, it may constitute an article in its own right, for example a postcard, which combines the advantages of a wide sheet of information with a means for holding that information in sealed condition until required. The sheet means in this configuration has the advantage that the sheet can be fully opened with a single movement once the sealing means has been opened. When the sheet means are designed for attachment to an article they will comprise, for this purpose, attachment means, preferably in the form of adhesive means and a particularly user-friendly configuration is obtained if the said sheet has diagonally opposite segments defined by the concertina folds, one segment being adapted for attachment to the article and the other being adapted to be pulled free to open the sheet fully with a single movement once the sealing means have been opened. To make the sheet means further user-friendly, the opening means may comprise at least one marked and/or weakened break line.
In one embodiment of the sheet means, which is particularly convenient because it requires only a single sheet of material to be cut out, the sheet has a tab projecting from its back with, in order going from the main concertina part of the sheet, a first adhesive back portion, a fold line, a cover portion which folds over to cover the main part when this is folded and a second adhesive portion on the opposite face to the first. When the sheet is folded with both sets of concertina folds and the tab is folded at the fold line, the two adhesive portions face in the same direction and the cover portion can then seal the main portion to the article.
In another embodiment of the sheet means, there is attached to the said sheet a separate cover piece, preferably in the form of a loop surrounding the folded sheet and attached thereto at a back corner segment thereof, the sealing means being provided with the opening means in the region of the free end of the folded sheet.
In another embodiment, which particularly simplifies manufacture, the second set of concertina folds in folding the sheet is arranged so that the penultimate folded section extends beyond one side of the underlying folded sections and has on the lower face of the projecting part adhesive fixing means, and so that the ultimate section has at least the ultimate thickness thereof extending beyond the other side of the underlying sections and has adhesive fixing means on the underside of its projecting portion. Both of these adhesive means are intended to be able to be unsealed and possibly resealable. The very first thickness of the first section may have adhesive fixing means on its underside (if the sheet means is not intended to come free when the two said adhesive fixing means are unsealed). The whole may be provided on a backing or substrate which itself is provided with adhesive to affix the whole to the article.
