Multi-cavity mold for a thermoforming machine used in the process of high-volume, continuous thermoforming of thin-gauge plastic products
A multi-cavity mould (1) for a thermoforming machine used in the process of high-volume, continuous thermoforming of a plurality of thin-gauge plastic products (2) from a preheated thin-gauge thermoplastic sheet (3) comprising an upper tool (11) and a lower tool (12) arranged in a cooperating manner; the lower tool (12) comprising a plurality of cavities (8) in which cavity moulds (8) are placed and a plurality of base plates (91) from which a plurality of supporting blocks (92) extend perpendicularly over a predetermined total height (a), situated between adjacent cavities (8), each of said supporting block (92) has a stepped profile comprising three substantially rectangular shaped zones (92a, 92b, 92c) and a fourth substantially isosceles trapezoid shaped zone (92d) in a vertical cross section, having a common symmetry axis.
Method of manufacturing a container
The method for manufacturing a container having a substantially stiff outer container and a readily deformable inner bag of thermoplastic plastic materials which do not form a weld connection with one another, with a container opening and holes in the outer container, wherein the method includes forming holes in the wall of the outer container at diametrically opposed positions, which lie on the intersection line of a plane defined by the base seam and the longitudinal axis of the container with the container wall and that a pin-shaped tool forces the inner bag through the holes by a predetermined distance from the wall of the outer container and thereby detaches it from the wall, whereafter a pressure medium is introduced through the holes into the gap between the inner bag and the outer container, which detaches the inner bag from the wall of the outer container.
Closure system for containers and related container and process for the realization
A closure system and method of forming containers comprising a closing element. The closing element is integrally sealable to the container at one of the openings to be closed, and a preferential separation zone between the container and the closing element, the closure system comprising a first guiding and/or coupling portion for guiding and controlling the movement of the closing element from a first blocking position, wherein the closing element is integral to the container, to a second unblocking position, wherein the closing element is separated from the container via the preferential separation zone. The closure system further includes a first thread on the insert and a second thread formed within the closing element.
Method for creating full color heat activated transfers
The present disclosure provides a method for transferring an image to a substrate that includes providing a transfer medium having at least one registration mark; printing an image on the transfer medium; covering the image with a backing layer, the backing layer not covering the registration mark; covering the backing layer with an adhesive layer; penetrating the adhesive layer and the backing layer with a cutting device at locations around the image, the penetrating of the adhesive layer and backing layer not penetrating the transfer medium; removing portions of the adhesive layer and backing layer from the locations around the image; and transferring the image to the substrate.
BOND ASSEMBLY JIG PREPARATION METHODS USING THERMOSETTING BISMALEIMIDE RESINS
A method for preparing a bond assembly jig (BAJ) includes forming a cutter relief groove in the BAJ, filling the cutter relief groove of the BAJ with a material, and curing the material after said filling.
Method and device for producing an optical coupling element made of elastomer
A method for producing an optical coupling element made of elastomer includes filling a free-flowing elastomer formulation or its constituents into a mold so as to produce a flat sheet whose thickness is adapted to a thickness of the optical coupling element that is to be produced. The elastomer formulation or its constituents is cured to form an inherently stable elastomer. Individual optical coupling elements are cut out of the flat sheet.
CLOSURE WITH RETENTION RING AND HINGE
The present invention relates to a new closure for a container, the manufacturing precursor that is converted into the closure, and the method of closure manufacture. The closure is comprised of a cap (usually threaded), a retention ring (that keeps the closure assembly connected to the container), and a hinge and articulating band that connects the cap to the retention ring. The closure is made by three major steps in the method: (1) polymer molding the closure, (2) scoring/cutting the closure, and (3) stamping the hinge which reorients the polymer. The hinge and articulating band elements are manufactured so that the band articulates and changes shape as the closure is opened. By necessity, the cap and the retention ring must separate as the cap is lifted or unthreaded; the articulating nature of the hinge and band feature allows it to keep the cap and retention ring connected as they separate. Even after opening the container, the cap remains attached to the container for convenience and anti-littering purposes.
Multi-cup arrangement for foodstuff packaging
The present invention provides a multi-cup arrangement comprising a polypropylene sheet, wherein the polypropylene sheet comprises at least two cavities, the cavities each protruding from the sheet from a bottom surface of the sheet, wherein the cavities are separated from each other via one or more spacer area(s) on the sheet, wherein the spacer area(s) each comprise one or more groove(s) on the bottom surface of the sheet that are positioned to allow the sheet to be broken along the groove by bending the sheet towards the top surface, wherein the grooves are positioned to divide the sheet into multiple segments, each segment comprising one or more cavities, wherein each of the groove(s) has a maximum depth of ?25% and ?80% with regard to the thickness of the polypropylene sheet. Such multi-cup arrangement may be separated into individual cup segments by moderate manual force, whilst the arrangement does not undesirably bend nor snap under the action of its own weight.
EXTRUDED FASTENER AND METHOD FOR MAKING SAME
An extruded integrated fastener assembly comprising a plurality of fasteners cut to length from an extruded length of material. Unwanted areas of material are cut away leaving the individual fasteners, which fasteners are also connected together by an expanse of material that remains. The fastener assembly can be single durometer or double durometer. A profile with retention members and/or leg features are formed in the fasteners for connecting to a predetermined component. The process for manufacturing the extruded integrated fastener assembly includes providing fabrication tooling suitable to cut away the unwanted area between the fasteners. The fasteners are thereby able to be cut to any desired length.
Molding method
A method of molding a composite structure having continuous fibers contained therein is disclosed. The method including the steps of compressing a first composite material in a mold; forming a cavity in the first composite material; placing a second composite material having continuous fibers contained therein in the cavity formed in the first composite material to minimize movement and distortion of the continuous fibers; compressing the first composite material such that the compression of the first composite material causes the first composite material to flow to edges of the second composite material; and allowing the first composite material to bond to the second composite material under molding temperature and pressure to form the composite structure.
