The present disclosure relates to an integrated liner-based system having an overpack and a liner provided within the overpack, the liner comprising a mouth and a liner wall forming an interior cavity of the liner and having a thickness such that the liner is substantially self-supporting in an expanded state, but is collapsible at a pressure of less than about 20 psi. The liner and overpack may be made by blow molding the liner and the overpack at the same time using nested preforms.

Nested blow molded liner and overpack and methods of making same

Overmolded containers and methods of manufacture thereof are disclosed, which may provide enhanced visual and tactile characteristics, enabling innovative packaging designs, improved grippability and thermal insulation. The containers can be made cost effectively manner, with minimal impact on polymer recycling streams. The methods of making the container include the steps of providing a container preform which comprises a thermoplastic polymer, such as a PET copolymer; overmolding an elastomeric material over at least a portion of the preform to form an overmolded preform; and blow-molding the overmolded preform to form an overmolded container. In one embodiment, the overmolded container is a beverage container.

Overmolded containers and methods of manufacture and use thereof

Combined bottle and closure

Container

The multi-chamber containers with a dispenser/doser are blow molded as a single integral item. They then are fitted with dip tubes with the dip tube fitment forming a seal in the transition of the container to the dispenser/doser. The dividing walls in the container are continued up into and through the dispenser/doser. A closure with a rotatable contact surface seals the container. The container preform is made by injection molding using an elongated gate pad in one embodiment in another embodiment an arrangement of recesses on the ends of the core projections with a complementary shaped gate pad. The webs of the container are of a thickness so that they flex upon a compression force being applied to the container walls.

Inspection mold for a multi-chamber container preform

Multi-chamber containers with a dispenser/doser portion are blow molded as a single integral piece. Each chamber can then be fitted with dip tubes with a dip tube fitment forming a seal in the transition of the container body to the dispenser/doser portion. The dividing webs in the container which form the container into multiple chambers are continued up into and through the dispenser/doser portion. The webs of the container body are of a thickness so that they flex upon a compression force being applied to the container walls. This compression force flows liquid in each chamber of the container body up through the dip tubes and into the dispenser/doser portion.

Base for a bottle

Multi-chamber containers are disclosed having at least a central web dividing the container into discrete chambers. A base for the container is provided which is generally outwardly convex having an inwardly arched lineal impression in the region of the juncture between the central web and the base. Outwardly extending foot portions in the base on either side of the lineal impression providing impact support for the container.
