A package includes a closure and a container. The closure is adapted to mate with a brim of the container to close a top opening arranged to open into an interior product-storage region formed in the container.

According to one aspect of the present invention, there is provided a hollow structure body having a hollow structure, in which a first shaped product constituted by a first fiber-reinforced resin material containing first reinforcing fibers and a first matrix resin and a second shaped product constituted by a second fiber-reinforced resin material containing second reinforcing fibers and a second matrix resin are combined, wherein in an arbitrary cross section in a direction perpendicular to an axial direction of the hollow structure, a ratio Sc/St between compressive strength Sc of a structure in the first shaped product and tensile strength St of a structure in the second shaped product satisfies formula (1):
(σc/σt)*(Hc/Ht)<(Sc/St)<(σt/σc)*(Hc/Ht)  formula (1).

Provided are a fuel tank made of polyketone and a method of manufacturing the same. The method includes injection-molding an upper cover and a lower cover using an injection-molding machine, placing the upper cover and the lower cover at a relatively high position and a relatively low position, respectively, assembling the upper cover and the lower cover with each other, and bonding contact surfaces between the upper cover and the lower cover to each other using a laser beam. Since the upper cover and the lower cover are formed at the same time and are bonded to each other immediately after being assembled by a machine, it is possible to achieve automated production, mass production and remarkable cost reduction. Further, since the fuel tank has sufficient rigidity due to the rigidity of polyketone without an additional reinforcing member, it is possible to manufacture a lightweight fuel tank.

An additional pad 27 is additionally and integrally arranged from an outer surface of a flange 17 opposite to a contacting side of the flange 17 to a small-diameter curved surface of a bend 19 and from there to an end of an outer surface of a part body 13. On an outer surface side of the additional pad 27, a fastening seat 27f is formed by machining. An area end PAe of a processed area PA formed by machining is positioned on the part body 13 beyond the bend 19.

A bleach compatible mattress cover made of a non-woven polyolefin material and defining an interior cavity. The interior cavity configured to receive a mattress structure which may include a first and second support structure disposed in the interior cavity. In certain embodiments, the mattress cover has a Moisture Vapor Transfer Rate of greater than or equal 400 to less than 10,000, 7500 or more particularly less than 5000 grams per square meter per day and a hydrostatic head of 100 cm or greater and passes ASTM 1670 and ASTM 1671.

Manufacturing capsules, comprising preparing a first and a second capsule element, at least the first element containing a cavity, each element, being provided with a peripheral ring, bringing the elements together, so that the rings are superimposed, placing the two elements between a sonotrode and an anvil, the anvil containing an anvil recess and a striking surface, surrounding the anvil recess, the sonotrode including a sonotrode recess, with the same cross-section as the anvil recess, and a working surface surrounding the sonotrode recess, wherein the striking and working surfaces are configures to come into contact with each other on a working area, extending around the recesses, clamping the rings between the working surface and the striking surface by the proximity of a sonotrode and the anvil, activating the sonotrode and directing the ultrasound towards the anvil, whilst maintaining the clamping action, wherein the rings are detached from the capsule.

A pouch exterior material that enables an electrode assembly to be easily mounted on an accommodating portion at a proper position, having an integrated shape and including an inserting portion provided at a center of the pouch exterior material and having a width equal to a thickness of the electrode assembly, accommodating portions provided symmetrically at two sides of the inserting portion and gradually deepening from a portion corresponding to a width center of the electrode assembly towards a portion corresponding to an edge of the electrode assembly, and a triangular stepped portion provided at two ends of the inserting portion and having a depth gradually decreasing towards an end.

Aspects of the present invention are directed to a heat sealed packaging wherein the heat seal is along a curved surface. Additional aspects of the present invention are directed to a device for heat sealing a package on a surface that is curved along the direction of force.

A friction welding method for fastening a connection bushing, such as a threaded bushing for example, in a housing. In order to improve the quality of the connection, the connection bushing is attached to the housing using a friction welding element. The friction welding element consists of the connection bushing, on which a friction welding shell with a radially outer friction welding contour is formed or molded. Connecting and sealing portions are produced between the friction welding element and the housing during the friction welding process by means of a special design of the friction welding contour.

A wind turbine with a wind turbine tower, a nacelle on the tower, a rotor hub rotatably mounted to the nacelle, and at least one wind turbine blade having a blade root mounted to the rotor hub, a tip end, a pressure side and a suction side connected to each other via a leading edge and a trailing edge, a first shell part having inner and outer surfaces and a second shell part having inner and outer surfaces, the shell parts having flanges that extend outwards from the trailing edge of the shell parts and away from the outer surface with gluing surfaces which are glued together when the two shell parts are placed on top of each other. This allows the glue line to be moved out of the inner area defined by the shell parts so that the glue process can be controlled more effectively.
