DISPOSABLE CUP

Disclosed is a disposable cup including an outer cup member (10) provided with vertical folding lines (21), and an inner cup member (30) received in the outer cup member (10). Each of the cup members (10, 30) has a size gradually reduced from its upper end to its lower end. The cup members, which are normally maintained at a folded state, are deformed into a cup shape when the vertical folding lines (21) are pressed. The outer cup member (10) has a tubular structure opened at its upper and lower ends while having a circular or diamond-shaped folding line (22) at a region where each vertical folding line (21) is pressed. Each vertical holding line (21) is provided at its lower end portion with a slit (24). The inner cup member (30) has a structure opened at its upper end while being closed at portions other than the upper end. Cette invention a trait à un gobelet jetable constitué de deux éléments, en l'occurrence d'un élément extérieur (10) possédant des lignes verticales de pliage (21) et d'un élément intérieur (30) venant se placer dans le premier (10). Les dimensions de chacun des éléments (10, 30) diminuent progressivement du haut vers le fond. Ces éléments, normalement pliés, retrouvent la forme d'un gobelet lorsque l'on appuie sur les lignes de pliage (21). La structure tubulaire de l'élément extérieur (10) est ouverte à chaque extrémité et porte une ligne de pliage en forme de diamant (22) sur les deux côtés où appuyer (21). L'extrémité inférieure de chaque ligne verticale de pliage (21) comporte une fente (24). Seule l'extrémité supérieure de l'élément intérieur (30) est ouverte.
