A manufacturing method for a high-pressure tank includes joining a cylindrical member and dome members to each other so that a first reinforcing layer and a second reinforcing layer to which a cap is attached are formed, and after a resin material is poured inside the first reinforcing layer, rotating the first reinforcing layer so that the resin material covers an inner surface of the first reinforcing layer, and solidifying the resin material so that the liner is formed. The cap is attached to the first reinforcing layer so that a recessed portion in which the resin material is collected is formed between the cap and the first reinforcing layer. After the first reinforcing layer is rotated, the resin material is solidified in a state where the cap side is positioned on a lower side.

Molded pulp containers with fused junctions and methods of making of same are provided. The present invention provides a pulp container, comprising a molded pulp body, wherein the body comprising a bottom and at least one side wall forming a wherein the at least one side wall comprising a upper rim, a neck, wherein the neck comprising a upper closure part and a lower rim, a fused junction, wherein a part of the upper rim of the at least one sidewall of the body and a part of the lower rim of the neck are aligned and fused together. The fused junction may be formed by ultrasonic welding.

A dispenser (10) for dispensing flowable materials has a container (12) having an outer wall (16) and a membrane (34) collectively defining a first chamber (18) configured to contain a flowable material. The membrane (34) extends from the outer wall (16) at an angle. The membrane (34) has a thickness and a weld seam (40), and the weld seam (40) has a thickness less than the thickness of the membrane (34).

Container of a bag-in-container type, wherein a neck region of the container is provided with at least one opening extending substantially radially there through, into a space between the outer container and an inner container adjacent thereto, wherein the neck region is provided with coupling elements, preferably at opposite sides of the at least one opening, seen in circumferential direction, for coupling of a connecting device to the container for introducing a pressure fluid through the at least one opening into a space between the inner and outer container.

Collapsible tunnel systems or segmented tubular structures may be printed on or otherwise attached to base layers on articles of apparel, articles of footwear, or other articles of manufacture. The collapsible tunnel systems have two or more tubular structures attached to the base layer, with tunnels extending through the tubular structures. A tensile strand may be laced through the tunnels in the tubular structure such that when tension is applied to the tensile strand, the tunnels may collapse into a structure with a continuous tunnel through two or more tubular structures. In some embodiments, two or more segmented tubular structures each have two spaced-apart tubular structures joined by a connecting portion, and a tensile strand extending through tunnels in the tubular structures.

Compositions of high molecular weight poly(hydroxy acid) polymer having good thermal stability and a weight average molecular weight of >100,000 by GPC. The compositions include one or more chain-terminator compounds/impurities which may be incorporated into the polymer and rendered harmless by the presence of appropriate amounts of bi-functional and multi-functional polymerization initiators. A process including first mixing glycolic acid and/or lactic acid (with chain-terminators), and a diol or di-acid initiator, and at least one multifunctional initiator to form a liquid monomer mixture in an agitated polycondensation reactor. Next, polycondensing to form a liquid reaction mixture comprising a pre-polymer having a weight average molecular weight of >10,000 by GPC, and greater than 80% by mole hydroxyl or carboxyl end-group termination, then crystallizing to form a first solid reaction mixture. Then, solid state polycondensing the solid reaction mixture to form a solid reaction mixture having a moisture level less than 50 ppm by weight. Then, mixing the solid reaction mixture with an appropriate reactive coupling agent in a melting and mixing extruder to couple and form the reaction mixture and form the final poly(hydroxy acid) polymer.

Device for packaging and dispensing drops of a substance for ophthalmic use, generally fluid, semi-fluid or in suspension, emulsion or oily solution including a dispensing accessory with a first valve made of an elastomer material that allows the substance to pass through when the dispensing accessory is stressed, without allowing outside air to pass through in the opposite direction when the dispensing accessory is relaxed, characterized in that the first valve is covered by a layer of Parylene.

A method of forming a printed structure is disclosed. The method may include printing layers of a printed structure and incorporating an element within the printed structure. The element may be removed in order to form tunnels within the printed structure. In some embodiments the element may be removed and reused in the formation of additional printed structures. The element may also be retained to form a composite printed structure.

A method is disclosed for producing thin-walled small plastic parts having an average wall thickness of less than about 1.5 mm, wherein the small plastic parts are produced in a plastic injection-molding method from polyethylene furanoate (PEF) having a viscosity of, for example, 0.3 dl/g to 0.7 dl/g, for example, preferably less than e.g., 0.6 dl/g, measured according to a measurement method as per ASTM D4603, which polyethylene furanoate has an exemplary water content of less than 100 ppm in the plastic injection process.
