摘要： The lid of a box is pushed up from the main body of the box by injecting gas by use of one or more injection nozzles into a gap formed between the lid and main body of the box and then, with part of a top plate of the lid in contact with a lid rotating stopper, gas is further injected into the gap, or the lid is pushed up by injecting gas into the gap by use of one or more lower position injection nozzles and then gas is injected into the gap by use of one or more higher position injection nozzles in one or more stages, before the lid is opened from the main body. Thereby, it is possible to prevent the lids from being opened in a three-dimensional inclined state (in a one-side opened state) as well as to prevent the lid and main body of a box from being pushed upwardly simultaneously.
摘要翻译：通过使用一个或多个注射喷嘴将气体注入到箱体的盖体和主体之间的间隙中，将盒子的盖子从箱体的主体向上推压，然后与顶板的一部分盖子与盖旋转塞子接触，气体被进一步注入到间隙中，或者通过使用一个或多个下位置注入喷嘴将气体注入到间隙中而将盖子推上，然后使用一个或多个更高位置的喷嘴在一个或多个阶段中，在盖从主体打开之前。因此，可以防止盖子以三维倾斜状态（单侧打开状态）打开，并且防止箱体的盖体和主体同时向上推。
