The apparatus includes an operating unit, which can be a welding unit for welding a closing film to an edge zone of a containing element or a separating unit for separating containing elements from portions of sheet material. The apparatus includes a control unit programmed to enable the operating unit to selectively process a continuous strip of containing elements or discrete groups of containing elements.

It is provided an electronic control device including a resin molded body, a metal body, and an electronic component, wherein the resin molded body and a main surface of the metal body are bonded, and at least a part of a side surface continuous to the main surface of the metal body is in contact with a side contact portion provided in the resin molded body.

A plastic, internally hollow body has a cavity for containing liquid, solid or gaseous material and comprises a shaped main body and a closure body joined together by a joining element, overmolded to the main body and to the closure body. A method for producing the internally hollow body provides for joining the main body and the closure body in the same step wherein a second closure body and/or of a second main body to be used in a subsequent union step are molded to obtain a second internally hollow body. The internally hollow body is molded by means of a mold comprising punch impressions and die impressions and a movable shaped element which engages with the punch or with the die and which is movable to transfer the first main body from a main die or a punch impression to a union impression of a die or punch.

A flexible sealing tube is described that is adapted to be installed in and extend along a bore in the ground for use in a system for exchanging of energy with the ground. The flexible sealing tube has a first tube end to be installed at an inner part of said bore, and the flexible sealing tube is closed in the first tube end. The flexible sealing tube also has a first channel and a second channel extending in a longitudinal direction (L) of the flexible sealing tube, the first and second channels being in fluid connection with each other. The first and second channels are formed by the flexible sealing tube.

The apparatus includes an operating unit, which can be a welding unit for welding a closing film to an edge zone of a containing element or a separating unit for separating containing elements from portions of sheet material. The apparatus includes a control unit programmed to enable the operating unit to selectively process a continuous strip of containing elements or discrete groups of containing elements.

The invention relates to a welding tool and a method for pulse welding films of plastic for medical packs formed as bags. The invention generally provides for the film material that has been plastified during welding, and is consequently free-flowing, to be specifically displaced by increasing the sealing surface area. The displaced film material can for instance compensate for dimensional and form tolerances. At the same time, however, the strength of the welded seam region, which adjoins the interior space of the bag, is not reduced.

The invention relates to an explosion-proof housing and to a method for connecting a housing part and a cover part, wherein the housing is formed at least from a metal housing part with at least one housing opening and/or receiving surface and a support edge which borders said housing opening and/or receiving surface and with a cover part which covers the housing opening or receiving surface and comprises a peripheral cover edge. The cover part and the housing part are connected together in an explosion-proof manner. In order to improve such a housing such that a corresponding connection of the housing part and cover part can be produced in a simple and secure manner without the use of adhesive in order to form an explosion-proof housing and such that the housing part and the cover part have a high degree of connection stability, a plurality of connection points between the support edge and the cover edge is formed as interlocking depressions and protrusions, the protrusions being formed by partial melting the cover edge.

An apparatus for packaging a product comprises a packaging assembly to fix a film sheet to a support. The packaging assembly includes a lower tool having seats for receiving the support and an upper tool facing the lower tool and comprising a film holding plate for holding the film sheet. The film holding plate has an active surface for receiving the film sheet, where the upper and lower tools cooperating to define a packaging chamber. The packaging assembly is open to receive the film sheet in a first operating condition and is hermetically closed in a second operating condition. The film holding plate has a lateral surface extending substantially perpendicular to a plane defined by the active surface, the film holding plate comprising ejectors arranged in the lateral surface for ejecting a stream of gas substantially parallel to said plane and substantially away from a center of the active surface.

A method for producing a portion unit of a detergent by inserting a base element made from a first film portion into a deep-drawing mold that forms a holding volume from the first film portion, the holding volume having a plurality of chambers spaced apart from one another; pouring at least one detergent composition into the chambers; placing a cover element made from a second film portion onto the filled chambers; connecting the cover element to the base element, which forms a film wrapping, sealing seams being formed between adjacent wall portions of the chambers; removing the portion unit from the deep-drawing mold, wherein the outside of the film wrapping is then wetted at least in the region of the adjacent wall portions and, by pressure being exerted, the sealing seams are compressed and the adjacent wall portions are brought into contact with one another and interconnected.

A package that is suitable for packaging an article for collecting or administering a pharmaceutical active substance is disclosed. The package includes a first packaging component that includes a product-contacting sealant layer that includes a first ethylene vinyl alcohol copolymer. The package includes a second packaging component that includes a product-contacting sealant layer that includes a second ethylene vinyl alcohol copolymer. The ethylene content of the second ethylene vinyl alcohol copolymer is equal to or less than about 38 percent and the ethylene content of the first ethylene vinyl alcohol copolymer is greater than the ethylene content of the second ethylene vinyl alcohol copolymer.
