spell Thermoformed polyester resin closures for closing containers, the polyester resins including polyethylene terephthalate (PET), polyethylene furandicarboxylate (PEF), or a copolymer including PET and PEF, are provided herein. Methods of making the thermoformed closures are further provided. Methods of sterilizing the thermoformed closures are further provided.

A medical fluid container includes a container interior and a connecting piece that forms an inner channel. The container interior can be accessed from the outside via the connecting piece. The connecting piece has an outer thread on a connecting piece longitudinal section. The inner channel expands in a substantially conical manner in a region of the outer thread, starting from the container interior, to then preferably transition into a first cylindrical channel shape which extends to a free opening of the connecting piece. A method can be used for producing the medical fluid container from a container blank.

An injection mold for producing a sprinkler head part and related injection molding methods are described. The sprinkler head part includes a first, second, third and fourth mold portions. The first and second mold portions include first and second shaping elements structured to cooperatively form a body including a substantially cylindrical portion and a substantially planar portion, and two frame arms extending from the substantially planar portion of the body. The third mold portion includes a shaping element structured to form an orifice in the body of the sprinkler head. The fourth mold portion includes a shaping element structured to form a cross member connecting the two frame arms. The injection methods include injecting a composite material in molten form into the mold to form the molded sprinkler head part. The composite material includes thermoplastic polymeric resin and a plurality of reinforcing fibers dispersed in the resin.

A diffuser assembly includes a flexible diffuser membrane and a diffuser body. The flexible diffuser membrane defines a circumferential bead. The diffuser body defines a circular plate underlying the flexible diffuser membrane, and an edge ring covering a covered portion of the circumferential bead. The edge ring defines an inside surface that conforms to an outside shape of the covered portion of the circumferential bead. The edge ring is integral to the diffuser body. Such a diffuser assembly may provide a disposable diffuser assembly option with many advantages over conventional technologies such as improved ease of installation, lower weight, and lower cost.

A thread forming apparatus for forming threads in a rotational molding apparatus comprising a molding pin having a generally elongate shape, at least a portion of the molding pin having a threaded portion, the molding pin adapted to rotate along with the mold and receive the plastic material on at least the threaded portion, the molding pin being releasable relative to the mold such that once the plastic material coats the threaded portion of the molding pin and forms a threaded portion on the molded product, the molding pin is completely removed from the mold.

A cap for use in covering a portion of a fastener protruding from a surface is provided. The portion includes threads. The cap includes an interior, a base that at least partially delimits the interior, a threaded receptacle on the interior configured to threadably engage the portion of the fastener, and a seal coupled to the base to engage the surface.

A method comprises in sequence the steps of: dispensing a continuous polymeric extrudate in a molten state; separating from the continuous extrudate a dose substantially having the shape of a parallelepiped, the dose having a separation surface at which the dose has been separated from the continuous extrudate, the dose further having a face adjacent to the separation surface; conveying the dose towards a mould comprising a first mould part and a second mould part; shaping the dose in the mould by moving the first mould part and the second mould part one towards the other in a moulding direction arranged transversally to said face, thereby obtaining a dispensing part of a container. The dispensing part comprises: an edge zone suitable for being joined to a container body; a neck surrounding a passage through which a product contained in the container can be dispensed; a membrane which closes the passage, the passage being intended to be opened after the shaping step, so that said product can flow out.

An interdental brush with a replaceable brush body with a core and a manufacturing method thereof are provided, and relate to the technical field of tooth cleaning tools. The interdental brush includes a handle, a screw cap, a fixing block and a brush body. One end of the handle is provided with an external thread, an interior of the screw cap is provided with an internal thread mating with the external thread of the one end of the handle. One end of the fixing block abuts against the handle, and an other end extends out of the screw cap. The brush body includes a core and bristles, the core is twisted by an amorphous alloy wire, one end of the core is clamped in the fixing block, and a periphery of an other end is connected to the bristles.
