BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention concerns a package of preferably self-adhesive abrasive material such as circular disks or sheets arranged to a bundle with an abrasive-coated face of each sheet or disk of the abrasive material facing upwards, said sheets or disks of the abrasive material being attached to each others by means of a continuous carrying band passing along one side of the bundle and in loops in between each sheet or disk of the abrasive material, the upper portion of each loop being fixed to the abrasive-free side of the sheet or disk of abrasive material positioned above said loop, and the lower portion of each loop lying free between the upper portion of said loop and the abrasive-coated face of the sheet or disk of abrasive material positioned underneath, the bundle being inserted in a closed box having a dispenser opening at its top, at the proximity of and substantially parallel to a side edge.
BACKGROUND OF THE INVENTION
In the prior-art abrasive material packages such as disclosed in the German Patent Application No. 2 926 340, all abrasive disks are provided with a protective covering on their adhesive-coated side and are joined into a connected unit by means of separate adhesive-coated carrying bands, whereat each band is attached to the protective coverings of two adjoining abrasive disks. In the embodiment in which the abrasive disks are arranged in a bundle with their abrasive-coated faces facing in the same direction, each carrying band is folded in Z-form, whereat the length of the free portion of the carrying band equals the diameter of the disk. The bundle is inserted into a dispenser box with the abrasive-coated faces facing downwards. The dispensing of a disk is carried out with the lid of the dispenser in an opened position, whereby the carrying bands and the protective coverings are removed from the rigid abrasive disks when a carrying band is drawn around the front edge of the lid. The dust protection properties of such a dispenser are very negligible.
From the British Patent Specification 1 497 355 a method of storing and subsequently separating flat objects as well as a device for carrying out the method is known. The flat objects are stored substantially as disclosed in the introduction part of this specification. The dispenser opening of this prior-art device is positioned in the upper portion of a vertical side wall having no means to prevent more than one flat object to be dispensed simultaneously through the dispener opening. If self-adhesive abrasive disks or sheets were stored in such a device there would be no guarantie that only one disk or sheet were dispensed simultaneously through the dispenser opening.
SUMMARY AND OBJECT OF THE INVENTION
The object of the present invention is to eliminate the above mentioned problems. This has been achieved by means of a package which is characterized in that the box in or just below the dispenser opening is provided with a substantially horizontal edge portion projecting inwardly from a vertical side wall of the box adjacent to the carrying band of the bundle, which edge portion prevents more than the uppermost abrasive material in the bundle to be dispensed at the same time.
In the following, the invention will be described in more detail with reference to the accompanying drawing, wherein

DESCRIPTION OF THE PREFERRED EMBODIMENT
According to the invention, the abrasive material 1, in particular self-adhesive abrasive disks or sheets, is attached to a continuous carrying band 2 so that a connected unit is formed, said unit comprising a series of abrasive material pieces 1 following one after the other and possibly slightly overlapping each other. The connected unit is folded together to make a bundle 3 so that all the sheets or disks of abrasive material 1 in the bundle 3 are placed so that their side 1a provided with the abrasive mat
