Abstract: The present invention relates to a container for holding bulk material, comprising a closable inlet for the bulk material in the upper end of the container, a cross-sectional geometry tapering in the outlet direction for the bulk material and an outlet tube for the bulk material which is arranged adjoining in the outlet direction, and a first reversible mechanical closing device (A), which is arranged in the transition region between the container body and the outlet tube or in the outlet tube itself, and which, when opened, releases the bulk material from the container interior, and a second closing device (B) which reversibly closes the opening of the outlet tube, and the second closing device is a cover which is pressed flush on the opening of the outlet tube by a closing device, wherein there is a seal at least on the contact surface of the cover which contacts the rim of the opening of the outlet tube, which seal seals the outlet tube with respect to the external environment in a gas-tight and fluid-tight manner, characterised in that the cover is screwed onto or is pressed onto the opening of the outlet tube with a clamping ring or a bayonet closure.

Abstract: The invention relates to a method for producing bleached wood fibre material, comprising the following steps: a) delaminating wood particles, that are large and optionally pre-treated with chemicals and/or water, into modified wood particles; b) grinding the modified wood particles produced in step a) in one or a number of refiners; c) and optionally treating the material produced in step b) with oxidative or reductive bleaching agents. The method is characterised in that step a) and/or step b) are carried out in the presence of a composition Z, said composition Z containing one or a number of the following components (Z1) to (Z3): a salt of dithionous acid H2S2O4 (Z1); a compound (Z2) that generates the dithionous acid or a derivate of the dithionous acid; a salt of sulphurous acid (sulphite) plus sodium tetrahydridoborate (Z3); and optionally additives (Z4).
