The present invention provides a preform coating device (5) provided with: a rotating and holding part (9) that holds a preform (1) in a horizontal direction, and rotates the preform (1) about an axis (A) of the preform (1); and a dispenser (6) that has a slot (62) and discharges a coating liquid in a plane form from the slot (62) to the preform (1), wherein the discharge direction of the coating liquid is the direction of the normal to an outer peripheral surface of the preform (1).

A plural preform assembly having nested preforms with an inner preform and an outer preform. The preforms are sealably joined together, defining a volume between the preforms. Propellant is disposed in the volume between the preforms. The preforms are later blow molded to provide a bag in bottle, bottle in bottle or similar container. The propellant charge is already present when blow molded, preventing the need for a later propellant filling step.

Three independent approaches to the reduction of gas molecule permeability through a polyethylene terephthalate (PET) polyester film or container wall by increasing the mechanically or thermally induced crystallinity or the overall crystallinity level of a single or multilayer container, where the three approaches may be employed independently or in combination with one another.

The invention relates to a dispenser container consisting of an outer container and an inner container for receiving a fluid, wherein the outer container and the inner container are formed from blow-moulded plastics, which do not form an integral connection with one another, and wherein a first plastic from which the inner container is formed has a higher elasticity than a second plastic from which the outer container is formed, such that the inner container is deformable, and wherein the outer container has at least one pressure compensation opening for pressure compensation in the region between the outer container and the inner container, wherein the inner container has a first outlet region and the outer container has a second outlet region, wherein the first outlet region can be shifted relative to the second outlet region in an outlet direction.

A synthetic resin-made container is a synthetic resin-made container that has an outer layer body and an inner layer body separably laminated on an inner surface of the outer layer body and is formed by stretch blow molding, and includes: a tubular mouth portion; a barrel portion connected to and located below the mouth portion; and a bottom portion closing a lower end of the barrel portion, wherein the outer layer body contains polyethylene terephthalate, the inner layer body contains polyethylene terephthalate, a laminate containing polyethylene terephthalate, or a blend containing polyethylene terephthalate, and has a vapor-deposited film having a gas barrier property on an inner surface thereof, and a rib that prevents the inner layer body from peeling away from the outer layer body when forming the vapor-deposited film is formed in at least one of a lower part of the barrel portion and the bottom portion.

The present invention relates to an integrally blow-moulded bag-in-container (2) having an integrally blow-moulded bag-in-container wherein the same polymer is in contact on either side of the interface between the inner (11) and outer layers (12). It also concerns a preform (1, 1′) for blow-moulding a bag-in-container, having an inner layer and an outer layer, wherein the preform forms a two-layer container upon blow-moulding, and wherein the thus obtained inner layer of the container releases from the thus obtained outer layer upon introduction of a gas at a point of interface between the two layers. The inner and outer layers are of the same material.

To provide a composite preform that can ensure that worsening of the appearance of a surface of a plastic member caused by near-infrared heating prior to blow molding is effectively prevented and that an inner preform is efficiently heated. The composite preform of the present invention includes a preform and a heat-contractive plastic member, the preform including a mouth part; a trunk part linked to the mouth part; and a bottom part linked to the trunk part, and the heat-contractive plastic member being disposed so as to surround the outside of the preform and including at least a colored layer that contains a resin material and a colorant, wherein the heat-contractive plastic member has a near-infrared transmittance of 50% or higher.
