Abstract
Preform assembly for blow moulding a container, comprising at least a first and a second perform, wherein the first perform is positioned inside the second perform before blow moulding the performs into the container, wherein each perform has a body forming portion having a wall thickness of less than about 8 millimetres, preferably less than about 6 mm.
Claims28
A preform assembly for blow moulding a bag in container, comprising a first preform extending at least partly into a second preform, wherein the first preform comprises a first neck portion and the second preform comprises a second neck portion, the second neck portion surrounding the first neck portion at least partly, wherein one or more openings are provided, wherein the at least one opening opens into a space between the first neck forming portion and the second neck forming portion,
- wherein a lid is provided for press fitting over the neck portion of the outer container formed from the preform assembly, said lid comprising an opening which opens into an inner volume of the inner container and a gas inlet opening which opens into said at least one opening in fluid connection with said space, said lid closing off said space.
A bag in container, comprising an outer container and an inner container, integrally blow moulded from a preform assembly comprising a first preform extending at least partly into a second preform, wherein the outer container comprises a first neck portion and the inner container comprises a second neck portion, the second neck portion surrounding the first neck portion at least partly, wherein a space is provided between the first neck portion and the second neck portion, wherein a lid is provided for fitting over the neck portion of the outer container formed from the second preform, said lid comprising:
- a first opening which opens into an inner volume of the inner container formed from the first preform, and
- a gas inlet opening which opens into said space,
- wherein said lid closes off said space.
A bag in container blow moulded from a preform assembly comprising a first preform extending at least partly into a second preform, wherein the first preform comprises a first neck portion and the second preform comprises a second neck portion, the second neck portion surrounding the first neck portion at least partly, wherein one or more openings are provided, wherein at least one of the one or more openings opens into a space between the first neck portion and the second neck portion, wherein said space is provided with and/or by spacers extending between at least part of the first neck portion and second neck portion, wherein an inner container or bag of the bag in container is formed of the first preform and an outer container of the bag in container is formed from the second preform, wherein the space between the inner and outer preforms is still provided in said container, comprising at least said spacers, wherein a lid is provided fitted on the neck portion of the outer container formed from the preform assembly, said lid comprising a dispensing opening which opens into an inner volume of the inner container and a gas inlet opening which opens into said at least one opening in fluid connection with said space, and wherein said lid is connected with an upper edge of the inner container, sealing off said space against the inner volume of the inner container.
A bag in container blow moulded from a preform assembly, wherein an inner container or bag of the bag in container is formed of a first preform and an outer container of the bag in container is formed from a second preform, wherein between first and second neck forming portions of the inner container and outer container a space is provided, comprising and/or formed by spacers extending between at least part of the first and second neck forming portions,
- wherein a lid is provided on the neck portion of the outer container, said lid comprising a dispensing opening which opens into an inner volume of the inner container for dispensing a carbonated beverage from said inner container and a gas inlet opening which opens into said space, and wherein said lid is connected with an upper edge of the inner container, sealing off said space against the inner volume of the inner container.
Method for forming a bag in container, comprising the steps of:
- injection moulding a first preform and a second preform;
- inserting the first preform into the second preform;
- integrally blow moulding the first preform and the second preform into a bag in container, having an inner container or bag formed from the first preform and an outer container formed from the second preform;
- fitting a lid onto the bag in container, said lid sealing against at least an upper edge of an first neck portion of the inner container and sealing against a second neck portion of the outer container, thereby closing off a space between the first neck portion and the second neck portion.
