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

The invention is an integrally blow-moulded bag-in-container obtainable by blow-moulding an injection moulded multi-layer preform. The bag-in-container includes an inner layer forming the bag and an outer layer forming the container, and a single opening, the mouth, fluidly connecting the volume defined by the bag to the atmosphere. The container further includes at least one interface vent fluidly connecting the interface between inner and outer layers to the atmosphere, wherein the bag is anchored to the outer layer at at least one point remote from the single opening and interface vent. The invention also relates to a process and a mould for the production of the blow-moulded bag-in-container.

A packaged article includes a packing bag which includes a welded portion that hermetically seals a container compartment in which a fluid content is contained. The welded portion includes a weak sealant section configured to be parted when the container compartment is pressed to communicate the container compartment and the exterior of the packing bag. A strong sealant section is configured to maintain a welded state at the time when the weak sealant section is parted. The container compartment includes a primary container section and a secondary container section. The secondary container section includes a narrow neck that is narrower than the primary container section in a width-wise direction, which corresponds to a direction in which the weak sealant section extends. The secondary container section is in communication with the primary container section at the narrow neck. The secondary container section is located adjacent to the weak sealant section.
