Ventilation board, ventilation box, ventilation system, insulating board and method for manufacturing ventilation board and box
US-8662378-B2用于通风和保温，如快餐包装盒。
专利摘要
本发明涉及一种通风板、保温板、通风系统以及包含所述通风板的制品和建筑应用，以及制造通风板的方法。所述通风板包括设有第一孔(5)的层(11)；设有第二孔(7)的相邻层(13)，第一和第二孔相对于彼此定位，使得它们不对齐且基本上不重叠；以及连接第一和第二孔的通道(9)，从而允许流体在它们之间通过。因此，包含所述通风板的纸箱在用于快餐包装时，提供足够的通风，使得从食物蒸汽冷凝的水不会流到纸箱内的食物上，并提供足够的保温，使纸箱内的食物保持温暖。
Original abstractThe present invention relates to a ventilation board, an insulating board, a ventilation system, and articles and architectural applications comprising said ventilation board and a method of manufacturing the ventilation board. The said ventilation board comprises a layer ( 11 ) provided with a first aperture ( 5 ); an adjacent layer provided ( 13 ) with a second aperture ( 7 ), the first and second apertures being located relative to each other such that they are non-aligned and are substantially without overlap; and a passageway ( 9 ) interconnecting the first and second apertures thereby permitting the passage of fluid therebetween. Therefore, the carton comprising said ventilation board when used for fast food packaging provides sufficient ventilation of the carton so that water condensed from food vapors does not run on to the food in the carton, and sufficient insulation so that the food in the carton is kept warm.
