Abstract: Cassette, designed to receive a stack of flat objects such as diskettes and compact discs, which cassette comprises a box part and a cover part, which can be fitted one inside the other in a sliding fit. In one of the parts, moreover, an element is present having a step-shaped series of supporting points, by means of which the objects located in the cassette lie mutually aligned in a first defined mutual position--storage position--of the box part and cover part, whilst in a second defined mutual position--usage position--they assume a height which steadily increases in the stack. The box part and cover part are mutually hinged near one of the corners. The side wall of the box part which is situated next to the hinge axis is provided with an opening at a short distance from the bottom wall, and the element having the step-shaped supporting points is fitted to the side wall of the cover part between the hinge axis and the opening in the box part.

Abstract: A file, formed by a rear panel, a spine part and a front panel, interconnected by means of flexible strips (live hinges), a file mechanism being disposed on the rear panel, near the spine part. According to the invention the rear panel, the spine and the front panel are designed as a case made of plastic, provided with raised edges closing against each other, with a grip formed by two grip parts on the (long) side of the front and the rear panel facing away from the spine. A case for storing documents, made up of two shell parts of plastic which are both hingedly connected to a spine part, and which are provided with raised edges closing against each other, with a grip formed by two grip parts on the (long) side of each of the shell parts facing away from the spine. According to the invention a file mechanism is provided on one of the shell parts, near the spine part, while the width of the shell parts corresponds essentially to the width of A4 format plus the width of the file mechanism.

Abstract: Disclosed is a separable key holder comprising a holder body in which a pin is fitted on either side, each pin being provided with a ring-shaped element for the accommodation of keys. The holder body consists of two portions to be detachably coupled to each other, each of the portions carrying one of the pins. The two portions of the holder body are coupled to one another by a snap connection which can be released by an axial displacement of one of said pins in the respective portion of the holder body.
