## Abstract

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.

## Claims

### Claim 1

A mould for the production of a blow-moulded bag-in-container having
an inner layer forming the bag and an outer layer forming the container;
a single opening, the mouth, fluidly connecting the volume defined by the bag to the atmosphere; and
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 said single opening and interface vent;
said mould comprises at least one point a sump which creates an anchoring point between the inner and outer layers upon blow-moulding of said container, said point being remotely located from the container's opening mouth, further comprising specific heating means to enhance physical or chemical adhesion between the inner and outer layers, said specific heating means located at the desired anchoring area.
