Abstract: A blade means for a mixer, such as for example an immersion blender or stand mixer includes a rotational shaft; at least one blade which extends from the rotational shaft and has at least one cutting edge; and a plurality of serrations which are formed in the at least one cutting edge. The individual serrations are spaced apart from one another by a planar portion of the at least one cutting edge, wherein the planar portion of the at least one cutting edge is less sharp than the serrations.

Abstract: A container for storing food includes a container wall with a top edge and a lid. The lid includes a lid edge with a sealing profile which contacts the top edge of the container wall when the container is closed, an opening with a valve which can have air be sucked therethrough when the container is closed so as to obtain a negative pressure inside the container, the negative pressure being lower than atmospheric pressure, a lid interior region, and a flexible profile which attaches the lid interior region to the lid edge so as to form a variable-height support of the lid interior region. The flexible profile maintains the lid interior region in an upper position if the negative pressure is not present and allows for a movement of the lid interior region into a lower position if the negative pressure is present.

Abstract: The invention relates to a holder for the lid (7) of a pot-type or dish-type serving vessel (1) such as a cooking vessel, the holder being used to hold the lid on the serving vessel in an upright position after the lid has been removed. The holder is characterised by an attachment in the form of a ring (2) which can be attached to the upper rim of the serving vessel and which has a ring opening (5) that can be sealed using the loose, free lid (7), wherein the ring (2) has at least one support (10) forming stops and being used to hold the lid (7) in an upright position on the ring.

Abstract: A device for sharpening a knife. The device includes an enclosure, first and second grinding strips, first and second grinding strip holders, and first, second, third and fourth pendulum rods. Each of the first and second grinding strip holders have a lower section. The first grinding strip holder holds the first grinding strip and the second grinding strip holder holds the second grinding strip. The first and second grinding strip holders are movably arranged next to each another in the enclosure so that the first and second grinding strips intersect to form a movable sharpening slot having a V-shape. The first and second pendulum rods are hinged to the first grinding strip holder at the lower section via a lower joint. The third and forth pendulum rods are hinged to the second grinding strip holder at the lower section via a lower joint.
