ABSTRACT:
A container, a container receiving sleeve cap and a process of unloading and receiving a filled material at a receiving facility that does not require expensive, exclusively specialized areas, such as clean rooms, for preventing the filled material from being contaminated or mixed with foreign matter when transported in a flexible and economic container. The container includes a double layer structure having an outer shell positioned about a flexible inner containing member, such as a bag. The process includes providing such a container having a blade cover with a tying member positioned at the lower surface of the container. The process also includes untying the tying member, positioning an outer shell unloading mouth away from the lower end of an inner bag unloading spout and securing it to an unloading frame receiving member. An inner bag unloading spout over-cover is then secured to an outer surface of a receiving sleeve. After the unloading spout over-cover has been secured, a sealed end of the inner bag unloading spout is opened using the container receiving sleeve cap and the filled material is unloaded and received in the receiving sleeve.
