在与袋的口部相邻的位置具有通向大气的界面通风孔的一体吹塑内装袋容器；用于制造该内装袋容器的预制坯；以及用于生产出该预制坯和内装袋容器的方法
摘要：
本发明是一体吹塑内装袋容器(2)和用于制造该内装袋容器的预制坯(1)。内装袋容器(2)具有形成袋的内层(21)和形成容器的外层(22)、以及将由该袋限定的容积流体地连接至大气的口部(5)。该容器还具有至少一个将内层和外层之间的界面(14)流体地连接至大气的界面通风孔(3)，其中，所述至少一个通风孔(3)平行于内层(21)和外层(22)之间的界面延伸，并在与内装袋容器的口部(5)相邻且定向成与该口部同轴的位置(4)通向大气。本发明还涉及用于制造如上所述的预制坯和内装袋容器的方法。
摘要（英）：

The invention is an integrally blow-moulded bag-in-container (2) and preform (1) for making it. The bag-in-container (2) has an inner layer (21) forming the bag and an outer layer (22) forming the container, and a mouth (5) fluidly connecting the volume defined by the bag to the atmosphere. The container further has at least one interface vent (3) fluidly connecting the interface (14) between inner and outer layers to the atmosphere, wherein the at least one vent (3) runs parallel to the interface between inner and outer layers (21) (22) and opens to the atmosphere at a location (4) adjacent to, and oriented coaxially with the bag-in-container's mouth (5). Processes for manufacturing a preform and a bag-in-container as defined above are defined too.
