Abstract: The invention relates to a container for ingredients for making beverages in the form of a rotation-symmetric truncated cone which is open at the larger bottom end of the truncated cone and closed at the smaller top end of the truncated cone by a top section of the truncated cone which preferably is of a flat, rounded, inclined or dented form or a combination of these forms, wherein the larger bottom end of the truncated cone can be closed by a base plate or membrane and can have an outward flange section to which the base plate or membrane can be attached, and wherein the thickness of the container wall is non-uniform, the container wall forming one or more circumferential stiffening rings which cover 10 to 50% of the container height, and wherein the wall thickness of the stiffening rings is at least 50% higher than the wall thickness in the remaining container wall outside the stiffening rings, the container having a maximum height of 5 cm and a maximum diameter without flange of 6 cm.

Abstract: A muscle trainer comprising curved, elongate spring elements is disclosed. The spring elements are arranged with facing concave sides and include end areas formed at each of the ends of the spring elements. The muscle trainer includes a first joint element being formed at a first end area of each spring element and a second joint element being formed at a second end area of each spring element. The spring elements are connected at their two end areas via joints formed from the joint elements. The first joint elements are designed as brackets having a bend in the direction of the concave side of the respective spring element and in each case at least partially enclosing the second joint element of the respective other spring element. A method for producing the muscle trainer and its use as a hand trainer are disclosed.
