Patent

CA 2289934

A folder comprising a sheet (1) which is pleated in a concertina-like fashion (10, 11, 12) and which, in a pleated state, is folded around fold lines (14, 15) that extend perpendicularly to the pleat line (10, 11, 12) in said pleated sheet, wherein the sheet (1) is surrounded by a protective cover (2) when in a fully folded-up state. The two sheet fold-lines (14, 15) extending perpendicular to the pleat lines (10, 11, 12) face in mutually the same direction, so as to enable the two end-panels of the pleated sheet (1) to be folded in overlapping relationship with the centre panel. The cover (2) is a paperboard cover against which one pleated panel (40) of the sheet is fastened in a centered position on one side of the cover (2), wherein the cover also includes fold lines (24, 25) which coincide generally with the fold lines (14, 15) on the sheet (1). The cover is provided on the inner (23) of the two mutually overlapping outer panels (21, 23) a tongue (26) which receives therebeneath the free end of the outer (21) of the two mutually overlapping outer panels (21, 23), which panels also overlap the centre panel (22) when the folder is in a fully folded-up state.

L'invention concerne un étui comprenant une feuille (1) pliée en accordéon (10, 11, 12) et laquelle, à l'état plié, se trouve pliée autour de lignes de pliage (14, 15) perpendiculaire à la ligne de pli (10, 11, 12) se trouvant dans ladite feuille pliée, ladite feuille (1) étant entourée d'une couverture de protection (2) lorsqu'elle se trouve à l'état complètement plié. Les deux lignes de pliage (14, 15) de la feuille s'étendant perpendiculairement aux lignes de pli (10, 11, 12) se font face mutuellement dans la même direction, de manière à permettre le pliage des deux panneaux terminaux de la feuille pliée (1) en chevauchement avec le panneau central. La couverture (2) est une couverture en carton contre laquelle un panneau plié (40) de la feuille est fixé en position centrée sur une face de la couverture (2), de manière que la couverture comprenne également des lignes de pliage (24, 25) coïncidant d'une manière générale avec les lignes de pliage (14, 15) se trouvant sur la feuille (1). La couverture est ménagée sur la partie intérieure (23) des deux panneaux extérieurs (21, 23) se chevauchant mutuellement, une languette (26) recevant sous ceux-ci l'extrémité libre de la partie extérieure (21) des deux panneaux extérieurs (21, 23) se chevauchant mutuellement, lesquels panneaux chevauchent également le panneau central (22) lorsque l'étui se trouve à l'état entièrement plié.
