A mechanical interlock pin assembly includes a shaft having a first end and a second end. The mechanical interlock pin assembly includes a set of helical spline elements disposed at the first end of the shaft, the set of helical spline elements extending along a longitudinal axis of the shaft. The mechanical interlock pin assembly includes a bearing rotatably coupled to the second end of the shaft, the bearing configured to allow rotation of the shaft between a first rotational position and a second rotational position relative to a mold cavity.

A respiratory mask, a mould for a respiratory mask, as well as to a method for producing a respiratory mask are disclosed, in which manufacturability and usability of respiratory masks are improved. A respiratory mask is disclosed for administering a breathable gas to a patient, the respiratory mask comprising a first component formed from a flexible material and a second component formed from a material that is more rigid than the flexible material, wherein the first component is formed onto the second component by an overmoulding process.

A method of making a two-component piston, the two-component piston including a piston cover as the first component and a piston body as the second component. The piston cover is arranged adjacent to the piston body and is configured to be moved relative to the piston body.

A melting heater configured to melt joining end surfaces of a pair of semi-molded products in a case where the joining end surfaces are melted and joined to manufacture a molded product, the melting heater including: two glass plates arranged in parallel to each other; and a plurality of element heaters arranged in a unit having a flat plate shape as a whole between the two glass plates, in which the glass plate is subjected to surface processing for controlling infrared rays emitted from the plurality of element heaters.

A two-component piston for a cartridge includes a piston cover as the first component and a piston body as the second component. The piston has a first side and a second side, and a rear side of the piston cover arranged adjacent to at least a part of the piston body. A front side of the piston cover is arranged at the first side, and the rear side of the piston cover includes a valve member. The valve member is to be received within the piston body and to extend into the piston body towards the second side. The piston cover is configured to be moved relative to the piston body on actuation of the valve member and the piston cover is non-releasably connected to the piston body.

The radio-wave transparent cover includes a plastic transparent layer, a decorative layer provided on the rear-side surface of the transparent layer, and a plastic base layer provided on the rear-side surface of the decorative layer. The transparent layer has a peripheral part having a protrusion extending rearward. The protrusion defines a peripheral edge of the transparent layer. The protrusion has an inner circumferential surface forming a part of an engaging end projecting rearward from the protrusion. The decorative layer is provided in a region of the rear-side surface of the transparent layer adjoining the inner circumferential surface of the engaging end.

A method of forming a cap assembly comprises injection molding a cap in a first shot from a first polymeric material, wherein the cap has an opening at one end defined by a perimeter. Injection molding a tamper band in a second shot from a second polymeric material such that the tamper band is monolithically attached to the perimeter of the cap. The first polymeric material and the second polymeric material comprise dissimilar resins and the tamper band is configured to sever from the cap with no burrs remaining on the perimeter of the cap.

A molded plastic article having a bonded plastic portion 6 bonding a first body and a second body together; a connecting plastic portion 8, formed by solidifying the molten plastic flowing out from the plastic channel, having one end connected to the bonding plastic portion 6; and a flow tab plastic portion 7 formed by solidifying the molten plastic, connected to the other end of the connecting plastic portion 8 connected to the other end portion of the 8. A portion of reduced diameter 7a is provided to the flow tab plastic portion 7 on the connecting plastic portion side.
