A reusable plastic container is provided. The container includes a plastic container body having opposing side panels and opposing end panels. The container body also includes top side panel flaps attached to a top portion of each side panel, and bottom side panel flaps attached to a bottom portion of each side panel. The container body has top end panel flaps attached to a top portion of each end panel, and bottom end panel flaps attached to a bottom portion of each end panel. The top and bottom side panel flaps are each defined with respect to the side panels by a fold line. The fold lines including at least one scored portion and at least one welded portion.

An apparatus for thermally joining thermoplastic fiber composite components includes a pressurization arrangement for jointly covering, at least in a region of a joining zone, thermoplastic fiber composite components to be joined and applying pressure to the thermoplastic fiber composite components to press the thermoplastic fiber composite components against one another, at least in the joining zone, the pressurization arrangement being flexible, at least in some section or sections. A welding device is configured for welding the fiber composite components in the joining zone during pressurization. The pressurization arrangement and welding device are configured to weld the thermoplastic fiber composite components in a pressurized state in the joining zone. The pressurization arrangement is configured to maintain pressurization independently of the welding device until the joining zone solidifies. A cover is also disclosed for a pressurization device for thermally joining thermoplastic fiber composite components.

A method for joining composite rods with tubular shape includes internal and external collars applied to the ends of the composite rod and deformed via unidirectional compressive load applied by a clamp in the radial direction of the composite rod cross-section. The resulting plastic deformation of the metal collars and composite rod interlock those components to support both compressive and tensile loads.

The welding chip heats and melts the first welded part and the second welded part, and includes a projected part, a first extension part, and a second extension part. The projected part has a tubular shape with a bottom. One end of the tubular shape extending in a predetermined direction opens and the other end of the tubular shape is closed. The projected part is pushed into the first welded part and the second welded part in the predetermined direction from the opening one end of the tubular shape. The first extension part has a shape extending from a tube outer surface of the projected part and extending annularly around the predetermined direction. The second extension part has a shape extending from the first extension part to the opening one end of the projected part in the predetermined direction and extending annularly around the predetermined direction.

The invention provides a tool 10 of the invention for welding a PET gland 12 onto a PET bottle 14 for the fitment of a dispensing tap. The tool 10 is generically indicated as ultrasonic horn or sonotrode in the figure. The ultrasonic horn has a tapered serrated portion 16 which has a lead-in taper section 18 to initiate the melt of the plastics to be welded, and a knife section 20 (when required), being the cutting zone thereof, which in use cuts open a sealed spigot 22 so that the horn can enter into the spigot 24 for the welding operation.

The first electrode section (7a) and the second electrode section (7b) are formed such that the outer portion connected to the upper portion of the heating section (6) is thinner than the inner portion connected to the lower portion of the heating section (6). The heating section (6) and the first electrode section (7a) are interconnected by an R-shaped first connecting portion (21). The inner circumferential sloping surface of the heating section (6) and the second electrode section (7b) are interconnected by an R-shaped second connecting portion (22). The first and second connecting portions (21)(22) are formed such that R becomes larger from the upper end to the lower end, where the upper portion is thin and the lower portion is thick. The thickness of an intermediate portion (6b) is smaller than the thicknesses of the first and second connecting portions (21)(22).

The invention relates to a transverse-sealing unit (09) for producing transverse-sealing seams in a tubular-bag machine (01), the transverse-sealing unit (09) comprising at least one sealing bar (11) which comes into sealing contact with at least one effective area when transversely sealing the film tube (05), and the transverse-sealing unit (09) comprising a support element (12) in which the sealing bar (11) is fastened, and the sealing bar having at least two effective-area sections (13, 14, 15), and the first effective-area section (15) protruding slightly over the second effective-area section (13, 14). The sealing bar (11) is mounted so as to be displaceable on the support element (12) in the direction of its longitudinal axis.

A membrane cartridge including: a filtration membrane (2); and a support plate (3). The support plate (3) includes a reference surface, a first joint portion (32) protruding from the reference surface, and a second joint portion (33) retreated from the reference surface, the second joint portion (33) is provided closer to an outer edge (35) of the support plate (3) than the first joint portion (32) is, at least a portion of an outer edge portion (21) of the filtration membrane (2) is joined to the support plate (3) at the second joint portion (33), and a portion of the filtration membrane (2) inward of the outer edge portion (21) is joined to the support plate (3) at the first joint portion (32).

Systems and methods to improve weld quality are described. For example, certain systems and methods described use weld quality monitoring as feedback to an ultrasonic welding process to improve weld quality. Still other systems and methods provide improvement to double sided and single sided ultrasonic welding through the use of selected multiple pulses.
