Abstract: Baseplate (4) for a pallet container (1). The baseplate (4) is designed to accommodate the container section of a pallet container (1). To ensure run-off of the fluids which are present in the pallet container (1) towards an outflow opening with valve (6) close to a peripheral side of the pallet container (1), the baseplate (4) is constructed with a slope. This slope is such that, in the normal use position of the baseplate (4), this baseplate (4) is constructed with a downward slope to all sides from the center point of this place (4), whilst a peripheral gutter (13) is provided. The lowest point thereof is located at the outflow opening for the fluids.

Abstract: A container for bulk material, having side walls and a bottom, in combination with an insert of flexible material. The insert has side walls of the same shape as the side walls of the container and fits removably in the container. The insert has a tubular core spaced inwardly from the side walls of the insert, this core being of flexible material and having connecting elements that extend between the core and the side walls of the insert. The insert has a filling aperture, whereby during filling of the container with bulk material, the bulk material connects initially in the core and presses the flexible material of the core radially outwardly into a cylindrical shape.

Abstract: A high frequency magnetic field exposure meter for use in an induction heat sealing operation for heat sealing metal foil elements in closures to containers to be closed by the closures. The meter has a magnetic field sensing coil, a rectifier to convert the a.c. output from the coil to a d.c. output, an integrating circuit to integrate the d.c. output over an exposure period to an h.f. magnetic field, and a display device to indicate the integrated exposure value generated by the integrating circuit. During operation, the meter generates a quantitative reading indicating exposure to the h.f. magnetic flux as an integral of the magnetic flux, which generates the induction heating currents, over the exposure period during the induction heat sealing operation, and the reading provides a useful measure of the induction heating generated in an induction heat sealable closure.

At least two interconnected faces (4-6) are composed of hingedly interconnected rigid face halves (7,8) which are separated from each other along a diagonal hinge line (9). According to an embodiment, three faces (4-5) are made up of hingedly interconnected face halves (7,8) and a fourth rigid face (3) is hingedly connected to a face at the free edge (11) thereof.

Abstract: Method for producing a material embodying an interference pattern, in which there is solvent-coated a transparent, thermoformable lacquer on one side of a base film, which lacquer is capable of forming a releasable direct bond with the base film. The lacquer is dried so as to form a solid lacquer layer. An interference pattern is formed by embossing the side of the solid lacquer layer which faces away from the base film with a printing device carrying the negative of the interference pattern. The embossed side of the lacquer layer is clad with a metal layer. A substrate is glued onto the metal layer, and the base film is released from the lacquer layer. A second base film is provided with a second transparent lacquer layer, and an interference pattern is introduced in this second lacquer layer. Then the second lacquer layer is applied by means of a transparent glue onto the first lacquer layer, and the second base film is removed.

Abstract: Method of manufacturing a seam connection between body flanges (9) and end wall flanges (5) of a drum (11) by means of a seaming roller (14) which folds the flanges about eaach other, the essential difference with respect to prior art seaming operations being that the precurl (6) of the end wall flange (5), known in itself, is guided into the lower portion of the groove (15) of the seaming roller so that during the radial movement inwardly of the seaming roller (14) the flanges (5,9) may bulge outwardly in axial direction and form a so called cat's back by means of which the flanges and accordingly end wall (2) and body (1) are centered upon each other, whilst further a distance is provided between the upstanding edge (3) of the end wall (2) and the curvature (10) between body (1) and body flange (9) which distance during the seaming operation may be reduced.

Abstract: Method for preparing a closure of a container. The container is provided with an outwardly directed collar wherein a threaded ring is placed. After position of the threaded ring this is welded to the free edge of the collar.

Abstract: The invention deals with the butt-welded connection between the endwall and the body of a thermoplastic container. Contrary to the known connection the invention provides the endwall with an axially extending edge, which may form part of a gripping edge and which overlaps the weld, so that the weld beads are hidden, while further the area of transition between the endwall and its edge above the weld has an axial thickness which is in essence the same as the thickness of the endwall and the radial thickness of the axially extending edge of the endwall, so that the material flow of the plastic during molding of the endwall is more even.

Abstract: The invention relates to a container (1) of the type which can be stacked which container has a top surface with a pouring orifice (6) adjacent one edge of the top surface (2) and a handle (9,10) which forms an integral part with the bottom of a recessed portion (8) of the top surface (2,4) and which in its initial or normal starting position extends at a sharp angle with respect to the vertical axis of the container and in a plane which is perpendicular to the plane of symmetry through the vertical axis of the container and the vertical axis of the pouring orifice, which handle may resiliently be bent into an upright gripping position or a downwardly folded storage position in which position it is completely inside the recessed portion.

Abstract: A container for a drink comprised of a bag of flexible plastic material for drink compacting sheets (1,2) welded upon each other by means of spaced longitudinal and transverse seams (3,4,5 and 6) which bag by means of a strip (7) or sheet (23) has been provided with a space for the insertion of a straw (13) such that the welding seams of said strip (7) or sheet (23) are either at a distance from the seams of the bag or coincide with said seams, an opening being provided for the insertion of the straw. The straw is movable within the space for puncturing the inside wall of the space which is elastically deformable and elastically surrounds the outer perimeter of the straw after it has punctured the wall. The straw may be removed if the contents of the bag are only partially consumed, thereby forming a seal by the punctured wall pushing against the outside wall of the space under pressure from the contents therein.
