Abstract: A cover for a container that includes a lid portion and a collar element. The lid portion having a main body section surrounded by a peripheral sealing shoulder. The collar element having a peripheral collar sealing shoulder that includes a collar groove and wherein the lid portion is connected to the collar portion through a hinge element. The lid portion, collar element and hinge portion are formed as a unitary structure and the lid portion articulates from an open positon in which it is spaced apart from the collar element to a closed position wherein the peripheral bead sealing shoulder of the lid portion engages with the peripheral collar sealing shoulder of the collar element.

Abstract: Stable, concentrated, liquid preparations of 1:2 metal complex azo or azomethine dyes containing at most one sulfonic acid group are obtained by metallizing the metal-free azo or azomethine intermediates in form of their moist, almost salt-free washed, filter cakes with aqueous slurries of complex forming, preferably cobalt or chromium salts. Without isolation of the thus obtained metal complex dyes the dye slurries are then in situ converted into the stable, concentrated dye preparations by adjusting them to a final dye concentration.The dye preparations are produced in a very economic manner by avoiding any isolation of the metal complex dyes after the metallization step and by considerably reducing the amounts of effluents.The dye preparations obtained are suitable for the preparation of dye-baths or printing pastes which may be used in particular for dyeing and printing textile materials made of natural or synthetic polyamide fibres, and further of leather and paper.
