An electrochemical cell includes an electrode body which includes a positive electrode and a negative electrode and an outer package which is formed by overlapping a first member and a second member. The outer package includes: a housing portion which houses the electrode body; and a sealing portion which is formed along an outer circumference of the housing portion, by fusing and bending the first member and the second member, at a portion corresponding to the outer circumference of the housing portion.

An enclosure for an electronic device includes a housing having a wall defining a cavity that is configured to receive an electronic assembly therein. The wall includes a distal end having a tongue. A cap is sized to attach to the housing with a corresponding groove that is formed in a perimeter of the cap. A double shear weld joint is formed between the tongue and the groove such that flash from the weld is contained within the enclosure and is not visible on the exterior surface of the enclosure.

The containers are thermoformed in groups, filled, and closed. Then, the containers are separated, and placed adjacent to one another in such a manner that segments of their respective rims face each other and define between them a line of separation. On said line, at least one spot weld is formed that forms a breakable connection between the facing rim segments.

A plastic containing assembly is provided with a container including a containing member, a front reduced section formed with the containing member, and a shoulder between a front end of the containing member and the reduced section; and a hollow, externally threaded adaptor including an outer protrusion put on the reduced section, an inner projection inserted into both the front end of the containing member and the reduced section, a groove on an outer surface of the projection, a filler member between the groove and the protrusion, and an axial passage communicating with an open front end of the adaptor and the projection respectively. An ultrasonic welding machine may apply high-frequency ultrasonic acoustic vibrations to the filler member and melt same to join the shoulder, thereby forming a first joining layer; and melt a joining portion of the reduced section and the protrusion, thereby forming a second joining layer.

A method for producing a capsule, includes providing a base body made of a plastic and having a base region, a circumferential side wall, and a circumferential base body flange adjacent to the circumferential side wall; providing a cover made of a plastic; filling the base body with an extraction material; placing the cover on the base body so that a fastening portion of the cover contacts the base body flange, and fastening the cover flange to the base body flange by ultrasonic welding. When fastening the cover flange, an inner surface of the fastening section makes contact with a flange surface of the base body flange. A sonotrode having mechanical vibrations applied thereto is pressed against an outer surface of the fastening section or of the base body flange, and mechanical vibrations liquefy plastic material of the cover or of the base body flange.

A device for liquid-tight sealing of two partially overlapping packaging components. One of these is a tubular basic body. A further packaging component forms the packaging head or bottom, having at least one mandrel and one die. For the tubular basic body to be easily slid on to the mandrel and removed the expansion elements have sealing jaws which, in their working position, form a closed, encircling outer contour.

The invention relates to an extensible bearing element (28) intended to be arranged in a tool for sealing a bottom or a lid of a cardboard package on a body of said package, with a generally polygonal shape.

The extensible bearing element (28) has a cross-sectional profile comprising two parallel extension sections (36) extending along an extension direction (E), each connected, at one of their ends (36E), to a bearing section (38), such that the extension sections (36) and the bearing section (38) define an inflation cavity (30).

The extension sections (36) are configured so as to extend along the extension direction (E) during the inflation.

The bearing section (38) comprises a substantially flat free bearing surface (40), configured to come into contact with the package body, the bearing surface (40) extending along a plane substantially normal to the extension direction (E).

The bearing section (38) further comprises, at the junctions with the extension sections (36), beveled release portions (42).

The invention also relates to an inflation device (6) comprising such an extensible bearing element (28).

A fitting for use in fusion welding mating thermoplastic components includes a weld bead chamber to capture and conceal a bead formed as a result of the fusion weld. The weld bead chamber integrates the bead into the fitting so that the joined parts have a finished look without mechanical polishing or grinding of the completed piece. A stop ledge included in the weld bead chamber prevents over insertion of a pipe or other component into the fitting. A view window in the fitting permits inspection of the finished bead.
