A method for producing a container having a threaded wide neck, includes steps of: heating a preform having a polyester body, on which there is mounted a polyolefin sleeve positioned next to an area of the body corresponding to the wide neck of the container; introducing the heated preform, with the sleeve, into a mould having the footprint of the container, including a threaded area having the footprint of the wide neck; injecting a pressurised fluid into the preform in order to form a blank of the container including a lower portion including the wide neck with a thread formed in the sleeve and an upper portion above the wide neck; separating the upper portion from the lower portion that thus forms the container.

Method of making a blow molded article from a preform including: a) providing a preform of a thermoplastic material having a plurality of effect structures each having an effect surface having a normal with an orientation, the preform having a body with one or more walls and an opening, wherein at least a portion of the one or more walls of the preform has a three-dimensional pattern of cavities and/or protrusions thereon; and b) blow molding the preform to form a blow molded article, wherein the step of blow molding the preform changes the orientation of the normal of at least some of the effect surfaces of the effect structures to create a visual effect in at least one wall of the blow molded article.

A blow molded monolayer article. The article has a hollow body defined by a wall. The wall has one or more regions comprising a first composition and one or more regions formed by a second composition.

A preform for an integrally blow-moulded bag-in-container uses an inner layer and an outer layer, wherein the preform forms a two-layer container upon blow-moulding, and wherein the 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. At least one of the inner and outer layers includes at least one additive allowing both inner and outer layers to reach their respective blow-moulding temperatures substantially simultaneously.

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.

Container of a bag-in-container type, wherein a neck region of the container is provided with at least one opening extending substantially radially there through, into a space between the outer container and an inner container adjacent thereto, wherein the neck region is provided with coupling elements, preferably at opposite sides of the at least one opening, seen in circumferential direction, for coupling of a connecting device to the container for introducing a pressure fluid through the at least one opening into a space between the inner and outer container.

A preform including: an opening portion; a body portion; and a bottom portion, the preform having a two-layer structure in which the body portion and the bottom portion include an inner layer made of a virgin material and an outer layer made of a recycled material, in which a weight ratio of the recycled material to a total weight of the preform is 50% by weight or more, a ratio of a thickness of the outer layer to a thickness of the inner layer in the body portion is 1.5 or more, and a haze of a body portion of a container molded from the preform is 1.8% or less.

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.

A method for manufacturing a thermoplastic container may include locally heating a middle zone of a thermoplastic tube; gripping the tube on either side by using retaining members; pulling the tube apart, causing a middle zone to narrow; pushing the inner wall of the middle zone against each other to obtain a closure; and cutting through the closed-off middle zone to obtain two separate tubular parts. Further is provided a system for pulling apart a tube, the system may include a first retaining member which is provided for insertion into the first zone via the first end and a second retaining member provided for insertion into the second zone via the second end, each retaining member being adjustable between a first position in which the retaining member fits inside the tube and a second position in which, in use, the retaining member exerts a pressure on the inner wall of the tube.

Multifluid dispensing system comprising a receptacle of container in container type and an atomizer Within the receptacle, between at least two of the component-units is provided a connecting-system that includes at least some of: at least one residual interface; at least one permanent-joint of adhesive or weld type; at least one reinforcing functional-form. The connecting-system preferably extends on the entire height of the receptacle. The parts of the connecting-system are preferably, at least partially, superimposed and contained within an operational-section. Additionally, within the receptacle is provided a partitioning-system that consists of at least one mobile-sector which develops via delamination from an internal component-unit. Within the receptacle is equally provided a compression-system that consists of at least one mobile-sector which also develops via delamination from an internal component-unit. The atomizer is made entirely of plastic, is of multifluid type, comprises a return-spring having two curved arms, and a precompression valve-system.
