摘要： Frozen dessert cones made from a cooked batter capable of having lower and higher moisture contents, which respectively cause the cone to assume dimensionally contracted and expanded states, are provided with sanitary jackets while in their dimensionally contracted state. When the cooked batter forming the cone attains a higher moisture content, the cone will dimensionally expand against the walls of the sanitary jacket thereby exerting a restraining force against removal of the jacket from the cone. The sanitary jacket is applied to an interior handle region of a cone so that the sanitary jacket will nest with the exterior surface of a downstream cone handle when stacked therewithin. A chute is provided so as to align and direct the sanitary jacket with respect to the interior handle region of the cone. A stream of pressurized fluid (e.g., air) is then preferably directed against the sanitary jacket so as to propel the same into a seated relationship with the interior handle region.
摘要翻译： 由能够具有较低和较高含水量的煮熟的面糊制成的冷冻甜点，其分别使锥体呈现尺寸收缩和膨胀状态，在其尺寸收缩状态下设置有卫生洁具。 当形成锥体的熟面糊达到较高的水分含量时，锥体将相对于卫生护套的壁尺寸地膨胀，从而施加抑制从锥体移除夹套的约束力。 将卫生护套施加到锥体的内部把手区域，使得卫生护套与其下方的锥形手柄的外表面嵌套。 提供滑槽以便相对于锥体的内部把手区域对准和引导卫生护套。 然后优选将加压流体流（例如空气）导向卫生护套，以将其推进到与内部手柄区域的就座关系。
