Abstract
Abstract The display unit comprises two transparent spherical segments which are preferably half spheres. Annular flanges formed at the edges of said segments are applied against each other and imprisoned between two superposed walls of sheet material which are joined together and form a support. The spherical segments project from both faces of the support through corresponding openings formed in both walls of the support. Essentially, only those parts of the two walls of the support which are located near the edges of the two spherical segments are joined together. The other parts can be moved away from each other so as to form a stand.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
129 words
A transparent display unit constituted by two transparent spherical segments which are preferably half spheres having edges bent back in the form of annular flanges which are applied flatwise against each other and imprisoned between two superposed walls which are joined together and made of sheet material which forms a support, said spherical segments being intended to project respectively from the two faces of said support through corresponding openings formed in the two walls of said support, wherein only those parts of the two walls of the support which are located in the vicinity of the edges of the two spherical segments are joined together whilst the other parts of said support can be moved away from each other so as to form a stand which constitutes bearing means.
Claim 2
Dependent Claim
129 words
A transparent display unit constituted by two transparent spherical segments which are preferably half spheres having edges bent back in the form of annular flanges which are applied flatwise against each other and imprisoned between two superposed walls which are joined together and made of sheet material which forms a support, said spherical segments being intended to project respectively from the two faces of said support through corresponding openings formed in the two walls of said support, wherein only those parts of the two walls of the support which are located in the vicinity of the edges of the two spherical segments are joined together whilst the other parts of said support can be moved away from each other so as to form a stand which constitutes bearing means.
Claim 3
Dependent Claim

A display unit as claimed in claim 7, wherein the support is constituted by a wide strip of sheet material which is substantially equal in width to the annular flanges of the two spherical segments and which is folded back in the vicinity of the opening and at least one end of which is folded inwards so that it may subsequently be withdrawn to form a stand for the display unit.
Claim 4
Dependent Claim
67 words
A display unit as claimed in claim 2, wherein the edges of that portion of the strip which is located in the vicinity of the spherical segments are fastened together by means of tabs having a folding line which is preferably provided with perforations and forms a line of incipient rupture of the display unit in order to enable the user to remove the packed article therefrom.
Claim 5
Dependent Claim
24 words
A display unit as claimed in claim 1, wherein the support is provided with suspension means consisting of a hole formed in said support.
