摘要:
Fluidführende Motorbaugruppe mit mindestens zwei längs einer Schweißnaht miteinander verschweißten thermoplastischen Kunststoffteilen (10,12,14), wobei die mindestens zwei Kunststoffteile mit von jeweils einem Wandbereich der beiden Kunststoffteile gebildeten Fügeflächen (50,52,54,56) gegeneinander anliegen und die Schweißnaht in diesen Fügeflächen liegt. Damit sich eine solche Baugruppe kostengünstig aus optisch dauerhaft ansehnlichen Kunststoffteilen mit kurzen Taktzeiten herstellen lässt, bestehen die die Fügeflächen überdeckenden Wandbereiche der beiden Kunststoffteile aus einem für Schweißlaserlicht zumindest im Wesentlichen undurchlässigen Werkstoff und wird zum Verschweißen mindestens ein erstes der beiden Kunststoffteile längs der Schweißnaht mittels eines heißen Gases aufgeschmolzen.

It is to provide a packaging container comprising: a synthetic resin container body (3) having a flange part (2) at a periphery of an opening at an upper end thereof ; and a container cap having a top board part (4) and a skirt part (5) provided such that it is suspended from a periphery of the top board part, and wherein the top board part (4) is heat-sealed onto an upper surface of the flange part (2) of the container body (3); wherein the packaging container has a first cutout part (7) at an upper end of an outer edge of the flange part (2). By providing a first cutout part (7), a packaging container possible to achieve sealing with the container cap stably, and to open the sealing easily and surely as well can be provided, by suppressing the effect of a molten resin on a folded corner part of the skirt of the container cap when the container body (3) is heat-sealed with the container cap.

The present invention relates to a plastic panel, and more particularly, to a plastic panel comprising am inner panel and an outer panel wherein bonding grooves to be coated with adhesive are formed on one of the inner and outer panels. According to a preferred embodiment of the present invention, the bonding grooves are formed on one of the inner and outer panels, while protrusions are formed on bonding surfaces of the other of the inner and outer panels. Accordingly, since the bonding grooves are formed at bonding surfaces on the inner or outer panel, the bonding grooves can serve as a guide when the adhesive is applied. Thus, the adhesive can be applied at a uniform thickness to correct positions even though it is manually applied, and even adhesive with certain fluidity can be prevented from leaking to the outside. Therefore, there are advantages in that the post-processing work for enhancing the external appearance is not required, the manufacturing time and costs can be reduced, and the bonding force can be increased due to the increased bonding area.

The invention relates to a tubular fluid transporting element which is fixable to a tube end by friction welding and comprises a body (1) wherein a tube end reception area (5) is arranged and provided with the input section (6) of the tube end and a weldable section (9) whose entry is delimited by a welding start-up surface (13.2). The reception area comprises a groove (8) between the input section and a the welding section, which receives a backed part of the tube end during welding and has a wall whose at least one portion forms the start-up surface and a stop edge for the backed part oppositely thereto. A friction welding method is also disclosed.
摘要:
A filter has a first case member and a second case member that are mutually joined to form a filter chamber, and a filter element that is held between respective joining ends of the first case member and the second case member. The first case member has laser permeability, and the second case member has laser absorbency. An element weld is formed by laser light on a contact area between the joining end of the second case member and the filter element.
