A method for joining at least two plastic parts (1, 5) along a predeterminable common joining point using infrared radiation (IR), is characterized in that each of the plastic parts (1, 5) to be joined is heated using infrared radiation at least along the joint by radiation sources without touching the respective plastic parts (1, 5). One radiation source is operated independently and spatially separated from the other radiation source. The radiation sources emit their respective infrared radiation to the respective plastic parts (1, 5) without contact and following the contour of the joint. The degree of heating by the respective infrared radiation is selected such that the joint is formed when the plastic parts (1, 5) are brought together.

Two workpieces 30, 40 are joined by means of ultrasound. First, a workpiece 30 with at least one energy direction sensor 31 and a second workpiece 40 are provided. The workpieces are brought into contact with each other in such a way that the energy direction sensor 31 comes into contact with a first surface 41 of the second workpiece 40. Ultrasonic vibrations are then introduced into one of the workpieces 40 via a working surface 11 of a sonotrode 10. A sonotrode 10 is used, which has a contour with contact lines 12 on the working surface 11. The sonotrode 10 is positioned with respect to the first workpiece 30 in such a way that the contact lines 12 run transversely to the energy direction generator 31.

A cartridge for a dispensing device contains at least one elongate film pouch, which is inherently non-rigid and which has a chamber for receiving a composition. The cartridge also contains a head part for interacting with the film pouch. The film pouch has an opening on a side facing the head part, which is closed by a cover. The cover has a predetermined breaking region. A method can be used for producing such a cartridge.

A plastic container and a method for producing a plastic container for liquids, in particular an inner container for transport and storage containers for liquids comprising an outer jacket made of latticework or of sheet metal material and a pallet-type understructure, the plastic container being realized as a blow-molded body by blow molding from a tubular preform in a blow mold and having a container socket for connecting a container fitting in a fitting connecting area of a container wall, the container socket being provided with a container opening and being connected to a connecting flange of the container fitting via a welded joint, wherein the container wall has an inner layer made of a first plastic material and an outer layer made of a second plastic material, and the container socket has a longitudinal cross section widening toward the container opening in such a manner that an end face of the container socket is formed at least in part by an inner layer segment disposed opposite the outer layer, and a welding contact surface of the container socket is formed by the inner layer segment.

A method for manufacturing a microprojection unit (10) according to the invention involves: a microprojection tool forming step of forming a microprojection tool (1) by bringing a projecting mold part (11) into contact from one surface (2D) side of a base sheet (2A) including a thermoplastic resin, and thus forming a protrusion (3) that protrudes from another surface (2U) side, and withdrawing the projecting mold part (11) from the interior of the protrusion (3); a joining step of joining the one surface (2D) side of the base sheet (2A), in which the microprojection tool (1) has been formed, and a tip end of a base component (4); and a cutting step of cutting the base sheet (2A), to which the base component (4) has been joined, along a contour (4L) of the base component (4) at a position more inward than the base component's contour (4L) in a planar view of the base sheet (2A) as viewed from the microprojection tool (1) side, to manufacture a microprojection unit (10).

A two-piece connection between a supply pipe from a source of water and a connection to a fire sprinkler with the connector having a first or rear section entirely above a ceiling and a second or front section connected to the first section with the connection entirely above a ceiling and the forward portion of second section connected to the fire sprinkler. The first connector section, located entirely above a ceiling, has a spherical male sidewall with a rounded leading edge and a rear portion of the second connector section has a spherical female interior surface.

The present invention provides a life jacket. In an embodiment, the life jacket includes a jacket member; and an air blowing member which is provided in the jacket member to inject air to the jacket member, wherein the air blowing member includes a base part coupled with the jacket member; and a tube part extending from the base part, wherein a flexible portion is formed in a part or the entire of the tube part.

Apparatus and methods of cleaning a sealing head (23) of a capsule filling line, comprising operating an ablation unit (10) to irradiate the sealing head (23) to ablate a residue off the sealing head (23).

A lid suitable for closing a metal can includes a metal ring onto which a peelable membrane is sealed. An inner annular part of the metal ring is equipped with a roll defining an annular space therebetween. The first connection portion of the roll and the second connection portion of the inner annular part opposite are sealed to one another by element of a heat-sealing material to form a seal sealing the annular space so at to protect the free edge of the roll. The invention also relates to a method for producing such a lid.

A two-piece connection between a supply pipe from a source of water and a connection to a fire sprinkler with the connector having a first or rear section entirely above a ceiling and a second or front section connected to the first section with the connection entirely above a ceiling and the forward portion of second section connected to the fire sprinkler. The first connector section, located entirely above a ceiling, has a spherical male sidewall with a rounded leading edge and a rear portion of the second connector section has a spherical female interior surface.
