A stretch blow-molded plastic container, including a container body, one longitudinal end of which is closed by a container bottom and to whose other longitudinal end is connected a shoulder section; and a container neck, which connects to the shoulder section, the shoulder section having at least two hinge-like areas that run in a circumferential direction, and which areas are arranged at a distance (a) from one another and in each case have a wall thickness (v, w) that is reduced compared to the adjoining areas, the stretch blow-molded plastic container having a total stretching ratio of greater than 11 for a longitudinal stretching ratio of 2.5 to 3.5.
Container Lid
The invention teaches a container lid product for controlling access to a container. The container lid comprises one or more hollow molded hinges with solid compressed area to eliminate any seam in use pivotally connecting the product to the container, a hollow-molded edge disposed adjacent to the one or more hollow-molded hinges, and a single-walled cover portion being connected to the hollow-molded edge. The single-walled cover has a length and a width and comprises a plurality of ribs extending the length of the single-walled cover. The single-walled cover has a peripheral rim with an undercut for stiffening. Each the one or more hollow molded hinges comprises an elongate knuckle. The hollow-molded edges comprises a top layer and a bottom layer.
Metallic bung closure with protective plastic layer
A bung closure for gas-tight and liquid-tight closure of a bung opening of a container, includes a cup-shaped basic body made from metal and having a disk-shaped base and an adjoining, upwardly open, tubular ring part; at least one interlocking element in the form of a shaped sheet-metal strip or a tab provided within the cup-shaped basic body for engagement with a screwing tool for screwing the bung closure into, and out of the bung opening of the container; and a stable plastics layer provided on the outer side of the ring part, with an external thread formed on an outside of the plastics layer for threaded engagement with the internal thread of the bung opening.
CUP LID
A liquid container includes a brim forming a mouth opening into a product receiving chamber formed in a cup. A lid is coupled to the rim to close the mouth of the cup.
Device and method for producing injection-molded parts which comprise different components
The invention relates to a device and a method for producing plastic moldings from at least two different sub-elements (15; 16) that includes first and second mold halves (3) and a rotatable center block (6) with center and third mold halves (8; 17) interposed therebetween. The center and third mold halves define first and second parting planes with the first and second mold halves. First cavities are defined in the first parting plane, into which a first plastic component is introduced to produce preforms (12). When the first parting plane is opened, the performs (12) remain on the center mold halves (8) and are brought into the second parting plane when the center block (6) is rotated, in which second parting plane second cavities are at least partially defined by the preforms (12), into which a second plastic component is introduced and first sub-elements (15) are produced. Second sub-elements (16) are produced in the additional cavities. When the second parting plane is opened, the sub-elements (15; 16) remain on the center and third mold halves (8) and are rotated into a lateral assembly position when the center block (6) is rotated.
STORAGE SYSTEM FOR STORING OBJECTS OF PLASTIC MATERIAL PROCESSED IN A BOTTLING LINE
A storage system for storing objects of plastic material processed in a bottling line (45) comprises: a plurality of drawers (4) configured to contain groups of objects (5); a frame (2) which defines a plurality of compartments (3) configured to house the drawers (4); a conveyor (8) movable in the storage system (1) itself and configured to access the compartments (3) in such a way as to withdraw and place drawers (4) from and into the compartments (4); a loading bay (11) having one or more loading compartments for receiving corresponding drawers (4) and having a loading manipulator (28) configured to place in the drawers (4) the loose objects (5) received from an infeed conveyor (29); an unloading bay (12) having at least one unloading compartment for receiving a corresponding drawer (4) and having an unloading manipulator (41) configured to place onto an outfeed conveyor (43, 44) the loose objects (5) stored in the drawer (4).
METHOD AND A DEVICE FOR PRODUCING A PACKAGE CLOSURE
A method for producing a package closure having a neck, a cap and an axis (A) includes a) by means of movable jaws and a tool core forming the neck with an outer thread and the cap with an inner thread, wherein an interior of the neck is formed by an outer first tool core part, and wherein an interior of the cap is formed by an inner second tool core part and a third tool core part, the thread of the cap being formed by the third tool core part, b) removing the jaws from the formed package closure, c) axially displacing the second tool core part in relation to the first tool core part and thereby separating the cap and the neck, d) axially displacing the third tool core part in relation to the second tool core part and thereby disengaging the cap from the third tool core part while keeping the second tool core part engaged with the cap, e) displacing the neck axially in relation to the cap and bringing the thread of the cap into engagement with the thread of the neck through an inherent flexibility of the package closure to form a package closure having a cap mounted on the neck, and f) displacing the package closure in relation to the second tool core part to disengage the package closure from the tool core.
Biaxially oriented polyester film for metal lamination
The invention relates to a multilayer biaxially oriented polyester film comprising a base layer B, an amorphous outer layer A and a further outer layer C, where this polyester film is suitable for lamination with metal sheets. The invention in particular relates to a polyester film which comprises (based on the mass of polyester) from 2 to 15% by weight of isophthalate-derived units in the base layer and which comprises more than 19% by weight of isophthalate-derived units in the amorphous layer A, and which has a silane-based coating on the outer layer A. The invention further relates to a process for the production of these films.
METHOD AND DEVICE FOR DETECTING A GEOMETRIC FEATURE OF MOLDED PARTS
A method and a device for detecting a geometric feature of consistent molded parts takes into account the different stages of cooling due to different durations of transport of the individual removed molded parts to the inspection system. Both the geometric feature and the temperature of each molded part is measured. The detected geometric features are corrected using a calibration function taking into account the measured temperatures.
IN-MOLD LID CLOSING APPARATUS
An in-mold lid closing apparatus includes a lid engagement member, a first actuation assembly connected to a first portion of the lid engagement member, a second actuation assembly connected to a second opposing portion of the lid engagement member, and a controller disposed in electrical communication with the first actuation assembly and the second actuation assembly. The controller is configured to transmit a first drive signal to the first actuation assembly and a second drive signal to the second actuation assembly to drive one of a linear position and a rotational position of the lid engagement member and to adjust at least one of the first drive signal and the second drive signal based upon a first feedback signal received from the first actuation assembly and a second feedback signal received from the second actuation assembly.
