A method for manufacturing carbon fiber, the method includes: placing a carbon fiber as an anode in an electrolyte, wherein the electrolyte is nitric acid, sulfuric acid, phosphoric acid, acetic acid, ammonium bicarbonate, sodium hydroxide, or potassium nitrate; and performing a surface treatment, wherein a surface of the carbon fiber is oxidized by active oxygen generated by anodic electrolysis, and thereby oxygen-containing functional groups are introduced to the surface. The disclosure also provides a carbon fiber composite bottle, which includes a bottle body and a carbon fiber. The bottle body is a type III bottle or a type IV bottle. The carbon fiber surrounds the bottle body, the surface oxygen concentration of the carbon fiber is 5-35%, and the surface roughness of the carbon fiber is 5-25 nm.

A thermoformed, reusable, recyclable shipping container comprising a thermoformed shell and a plurality of separate load bearing columns secured within said shell at various locations whereby the stacking load imposed on the containers will be at least partially borne by the load bearing columns.

A fluid cartridge and a method for eliminating mechanical stresses on an ejection head chip. The fluid cartridge includes a plastic fluid body having a front wall, a rear wall opposite the front wall, left and right side walls attached to the front wall and to the rear wall, a bottom wall attached to the front wall and the rear wall, and to the left and right side walls. A die bond member is attached to the plastic fluid body adjacent to the bottom wall and an ejection head chip is disposed on the die bond member so that the die bond member is between the bottom wall and the ejection head chip.

An internally reinforced thermoplastic container has a body manufactured using rotational molding. Prior to molding, attachment elements are releasably attached to the interior surface of parts of a mold, and an initially separate tension member is connected between the attachment elements. The mold is closed and a body of the container molded such that the attachment elements are integrated into the walls of the body. After molding, the attachment elements are released from the mold. The attachment elements and the tension member define a tension structure to resist outward bulging of the container walls. The tension member may be tensioned prior to or after molding of the container body. The attachment elements may take the form of eyelets having a base incorporated into the wall of the container body. The method enables the formation of a hollow thermoplastic container with integrally formed internal reinforcement.

The present invention relates to a container for a consumable good having an inner coating layer comprising antioxidant, a process for preparing such a container, and the use of said container for the storage of a consumable good, and the use of an antioxidant as an additive to coating layers of such containers.

A hot water storage device having a vessel includes a first section formed from a moulded material and a second section formed from a moulded material. An open end of the first section is sealingly engaged with an opposing open end of the second section to form the vessel. The first and second sections each have a generally cylindrical body portion and a closed end, comprising a head portion. The vessel includes a water inlet aperture moulded into the first or second section and a water outlet aperture moulded into the first or second section and wherein the inlet and outlet apertures are located on the body portion proximal to a tangent line between the body portion and the head portion.
