Patent

CA 2562150

A commercially viable paper wrapped foam cup (10, 100) comprising a taper portion (124, 126) that prevents the shrinkage-induced curling from interfering with the un-nesting of nested paper wrapped foam cups.. The paper wrapped cup (10, 100) further comprises a fillet (118) for strengthening the cup foot (18, 114) to retard shrinkage-induced curling of the foot. The paper wrapper (14, 104) has abutting to overlapping opposing ends (140, 142) to completely hide the foam cup (12, 102) to enhance the visual appearance of the cup. The overlapping portions of the paper wrapper are not bonded to each other to prevent wrinkling of the paper wrapper as the cup shrinks. A machine (200) and corresponding method provide for automatically supplying foam cups (12, 102) and paper wrappers (14, 104), wrapping the paper wrapped cup, and stacking the wrapped cups.

L'invention concerne une tasse en mousse revêtue de papier (10, 100), commercialement viable, dont une partie conique (124, 126) empêche le cintrage dû au retrait d'interférer avec le désemboîtement de tasses en mousse revêtues de papier imbriquées. La tasse en mousse revêtue de papier (10, 100) comprend également un filet (118) servant à renforcer le pied de la tasse (18, 114) pour retarder le cintrage du pied dû au retrait. L'emballage de papier (14, 104) présente des extrémités opposées de recouvrement attenantes qui cachent complètement la tasse en mousse (12, 102) pour accentuer l'aspect visuel de la tasse. Les parties recouvrantes de la tasse ne sont pas collées l'une à l'autre pour empêcher le plissage des emballages de papier pendant que la tasse rétrécit. On décrit une machine (200) et un procédé correspondant destinés à: présenter automatiquement des tasses en mousse (12, 102) et des emballages de papier; emballer les tasses revêtues de papier et entreposer les tasses revêtues.
