CA 2706374

A cup made of a paper material, and a method and a device for manufacture of a cup, are described. The cup contains a fillable interior formed by a conical sleeve and a bottom. The bottom is fastened to the sleeve at the lower end of the interior with a skirt in a substantially liquid-tight manner. A shoulder for holding an identical cup during stacking of several cups is arranged on the sleeve limiting the interior. The radius of the sleeve, seen towards the central axis of the cup, underneath the shoulder is at most just as large as the radius of the sleeve at the level of the bottom. The cup can have a thermally insulating outer sleeve.

L'invention concerne un gobelet (1) en matériau à base de papier, ainsi qu'un procédé et un dispositif pour produire un gobelet (1). Ce gobelet (1) présente un volume intérieur (6) pouvant être rempli, formé d'une enveloppe (2) conique et d'un fond (3). Le fond (3) est fixé de manière sensiblement étanche à l'enveloppe (2) à l'extrémité inférieure du volume intérieur (6) au moyen d'un rabat (5). Un épaulement (9) est formé dans l'enveloppe (2) délimitant le volume intérieur (6), et permet de retenir un gobelet (1) du même type lors de l'empilement d'une pluralité de gobelets (1). Dans l'axe du gobelet, le rayon (B) de l'enveloppe (2) au-dessous de l'épaulement (9) est plus petit ou égal au rayon (E) de l'enveloppe (2) à la hauteur du fond (3). Le gobelet (1) peut comprendre une enveloppe externe d'isolation thermique.
