  • the present invention relates to a storage container for holding a disc shaped element having electronically stored recordings thereon and having a cylindrical opening in the center of the disc shaped element.
  • the storage containers for these discs are commonly referred to as “jewel boxes", and the disc shaped elements are commonly referred to as compact discs or just "CD's".
  • the storage container has as a component thereof a tray on which the disc shaped element is seated. More specifically, this invention is directed to the storage tray for storing and securing a CD in place, wherein the tray has an improved centrally located circular arrangement of raised flexible cantilever members generally disposed around a raised seat and extending inwardly. The ends of the cantilever members form an essentially circular opening.
  • the central opening of the disc shaped element is secured over the circular raised flexible cantilever members.
  • the members are generally flexible in that they can move inwardly under slight pressure such as positioning the disc shaped element over the cantilever members and upon release of the pressure the cantilever members spring back or outwardly and secure the disc shaped element.
  • the circular cantilever member engages and secures the disc shaped element in place during storage.
  • the circular arrangement of the cantilever members is often referred to as a "rosette” and the cantilever members themselves are referred to as "petals” or "fingers".
  • the improvement is in the cantilever members wherein some or all of the members are fixedly held in place so as to have little or no flexibility. Any unfixed member will still, however, remain flexible.
  • Storage containers for holding one or more disc shaped element ⁇ having electronically stored recordings thereon are well known particularly in the entertainment field and in the information storage field. These storage containers for CD's are so designed to hold one or more such CD's.
  • one container arrangement or jewel box has an insertable tray such that a single CD container can be converted into a two CD holder by employing an insertable tray (U.S. Patent 5,284,243) without changing the dimensions of the jewel box.

Abstract

Ce plateau (46) de stockage comprend une série d'éléments (2, 6) saillants, flexibles, verticaux, disposés dans un agencement circulaire afin de permettre le stockage et l'immobilisation d'un disque compact, lequel est mis en place et immobilisé par lesdits éléments. L'amélioration réside dans la jonction, de manière fixe, d'au moins deux des éléments, tandis que l'on conserve une ouverture (10) dans le centre de l'agencement circulaire des éléments saillants. Cette jonction consiste en un anneau (4) reliant au moins deux éléments. De préférence, on relie seulement un élément sur deux. Cette structure, avec ses éléments ainsi joints, résiste à la casse lors de son expédition et/ou de sa manutention.
