CONTAINER AND MANUFACTURE THEREOF
A method of forming a container, the method comprising the steps of: providing an injection moulded preform composed of a biaxially-orientable thermoplastic material, the preform being substantially planar and having a peripheral edge and a central portion; clamping at least a portion of the peripheral edge of the preform in a frame; heating the preform; stretch blow moulding the heated preform, clamped with the frame, within a mould cavity defined by a first female mould to form an intermediate article having a bottom wall and an annular sidewall beneath an upper edge clamped within the frame, the stretch blow moulding step using a stretch rod to engage an inner side of at least the central portion of the preform and axially to stretch at least a part of the central portion of the preform prior to blowing a pressurized gas against the inner side which urges the opposite side of the preform radially outwardly against the mould; and shrinking the intermediate article, clamped with the frame, onto a second male mould to form a container having a bottom wall, defining a base, and an annular sidewall, defining a body portion, beneath the upper edge clamped within the frame, the container comprising biaxially oriented thermoplastic material in the annular sidewall and at least an outer portion of the bottom wall. Also disclosed is a wide mouth container which may be formed by the method.
Blow moulded container and manufacture thereof
A method of forming a blow molded container in the form of a tub, the method comprising the steps of: providing an injection molded preform composed of a biaxially-orientable thermoplastic material, the preform being substantially planar; heating the preform; and stretch blow molding the heated preform within a mold cavity to form a tub having a bottom wall and an annular sidewall having an upper edge, the tub comprising biaxially oriented thermoplastic material in the annular sidewall and at least an outer portion of the bottom wall, the stretch blow molding step using at least one stretch rod to engage an inner side of the preform and axially to stretch at least a part of the preform prior to blowing a pressurized gas against the inner side which urges the opposite side of the preform radially outwardly against the mold.
Integrally, Extrusion Blow Molded Container, Label and RFID Tag
An improved method for molding a plastic container within a mold including an RFID tag to generate a container which leaves a mold having an RFID tag bonded between the container and a label. This method provides for an improved integrally, extrusion blow molded container, label and RFID tag combination.
APPARATUS AND METHOD FOR FORMING PLASTIC PREFORMS INTO PLASTIC CONTAINERS WITH CLEAN ROOM
An apparatus for forming plastic preforms into plastic containers, having a transport device which transports the plastic preforms to be formed along a predetermined transport path, wherein the transport device has a rotatable transport carrier wherein a plurality of forming stations are arranged. The forming stations each have blow-molding devices within which the plastic preforms can be formed into the plastic containers by applying a flowable medium. The forming stations each have application devices for applying the flowable medium to the plastic preforms, and the apparatus has a feed device for feeding plastic preforms to be formed to the transport apparatus, and a discharge device for discharging formed containers from the transport device. The apparatus has a clean room within which the plastic preforms or the plastic containers are transported at least sectionally. The apparatus has an ejection device to eject plastic preforms or plastic containers from the transport path.
METHOD FOR PRODUCING A FLEXIBLE POUCH MADE OF FLEXIBLE THERMOPLASTIC MATERIAL
A method for producing a flexible pouch made of flexible thermoplastic material, including steps of: (i) preparing hot flexible thermoplastic material in a pasty state, (ii) placing a so-called proximal pre-molded insert onto a mounting such that the insert is arranged in a ring around the mounting, (iii) coating all or part of the insert with hot flexible thermoplastic material in the pasty state, (iv) locking the blow-mold shells around the insert, and (v) injecting a pressurized gas into the chamber so as to expand the sleeve from inside onto the inner surface of the mold or expand the sleeve from the outside by creating negative pressure inside the chamber.
Blow-molded container with in-mold label and method for manufacturing blow-molded container with in-mold label
A blow-molded container includes a container body having a body portion that forms a square shape in a cross-sectional view orthogonal to a container axis; and in-mold labels, which are integrally glued on outer peripheral surfaces of glued portions, ranging from corner surfaces to respective planar portions continuing on both sides of corner surfaces around the container axis, in body portion. Among front and back surfaces of in-mold labels, multiple recesses are formed over entire back surfaces, which are glued to the outer peripheral surfaces of the glued portions. When tensile elasticity of in-mold labels is E (MPa) and thickness of in-mold labels is t (mm), Et.sup.3 is 0.20 or less. When the radius of curvature of the corner surfaces is R (mm) and angle formed between the planar portions is () in a cross-sectional view of the glued portions, R.sup.2 is 45000 or more.
IN-MOULD LABELLING PROCESS
There is disclosed an in-mould labelling process for the manufacture of a labelled article comprising the steps of: feeding a labelstock web into a mould; forming an article in the mould such that the formed article contacts and effectively adheres to a label of the labelstock web; detaching the adhered label from the labelstock web; and removing the formed and labelled article from the mould.
In-mold labels and a labeled container
A technical problem of this invention is to create in-mold labels that can be adhered to wide areas, including 3D curved areas, of the peripheral wall of a synthetic resin container in a high-grade state without air entrapment and/or wrinkling. A principal means of this invention to solve the technical problem described above is in-mold labels used as an inserted material and adhered to the outer peripheral wall of a container main-body concurrently when the main body is being molded, said labels including an adhesive layer to be adhered to the outer peripheral wall of the container main-body, wherein this adhesive layer has depressed portions on a back surface thereof, the depressed portions being formed by embossing and being disposed in a regular pattern.
CONTAINER MANUFACTURING APPARATUS
A container manufacturing device is provided. In detail, the container manufacturing device for performing manufacture of a container pre-form and container molding in a single station via one stop. The container manufacturing device includes a pre-form molding module configured to form a shape of a pre-form of a container using a resin material, an injection module connected to the pre-form molding module and configured to supply the resin material to the pre-form molding module, a container molding module configured to inject air to a pre-form completed by the pre-form molding module to expand the pre-form and to form the shape of the container, and including a container mold, and a rotary table with a rib plate suspended thereon while rotating between the pre-form molding module and the container molding module, the pre-form or the container being mounted on the rib plate.
Process and machinery for integration of discrete parts into composite containers
A process of manual, semi-automatic and fully-automated integration of discrete components into a container that results in fast, reliable, cost-effective, and scalable production of composite containers is disclosed. The process can be embodied in manufacturing equipment that has a series of stations and may be called an assembly device. The equipment can produce containers, tubs, canisters, cartridges, etc. which are easily separated into different bio-degradable or compostable parts. Other container types are possible and are contemplated.
