Title
(EN) BAG FOR MICROWAVE COOKING
(FR) SAC POUR CUISSON DANS UN FOUR A MICRO-ONDES
Abstract
(EN)
A bag (10) for popping popcorn in a microwave oven has substantially rectangular front and back face panels (11, 12) and gusseted side panels (13, 14) joining the opposite side edges thereof. Top and bottom ends (15, 16) of the bag (10) are normally closed and sealed, but the top end may be opened for removal of popcorn. The gusseted side panels (13, 14) unfold during cooking to enlarge the interior volume of the bag (10), forming triangularly shaped corner flaps (30, 31 and 32, 33) at the junctures of the side panels (13, 14) and the front and back panels (11, 12), respectively. Spots of adhesive (24, 25) are placed between confronting surfaces between the triangularly shaped panels of the corner flaps to hold them in contiguous relationship to one another and prevent the formation of pockets to enhance popcorn yield. Preferably, the adhesive spots (24, 25) are placed between the confronting surfaces only at the back panel (12) and only at the closed bottom end (16).
(FR)
Sac (10) servant à faire sauter du maïs dans un four à micro-ondes et possédant des panneaux avant et arrière sensiblement rectangulaires (11, 12), ainsi que des panneaux latéraux à soufflets (13, 14) réunissant ses bords latéraux opposés. Les extrémités supérieure et inférieure (15, 16) du sac sont normalement fermées et scellées mais l'extrémité supérieure peut être ouverte, afin d'enlever le maïs grillé. Les panneaux latéraux à soufflets (13, 14) se déplient pendant la cuisson, afin d'agrandir le volume intérieur du sac (10), ce qui découvre des volets triangulaires (30, 31 et 32, 33) situés dans les coins au niveau des jonctions des panneaux latéraux (13, 14) et des panneaux avant et arrière (11, 12) respectivement. Des points d'adhésif (24, 25) sont placés entre des surfaces opposées des volets triangulaires, afin de les maintenir en position contiguë l'un par rapport à l'autre et d'empêcher l'apparition de poches, de façon à augmenter la production de maïs grillé. Ces points d'adhésif (24, 25) sont, de préférence, placés entre les surfaces opposées uniquement au niveau du panneau arrière (12) et de l'extrémité inférieure fermée (16).
