Abstract: Stopper assembly for a serving device configured to be positioned in a neck of a container, such as a bottle, wherein the stopper assembly comprises a body element arranged to fit in the serving device; a valve element mountable on the body element, wherein the body element extends substantially in a direction transverse to the valve element; and a handling element that is connectable to the valve element and extending in a direction substantially transverse to the valve element at an opposite side of the body element, such that the valve element is arranged in between the handling element and the body element.

Abstract: Pouring aid device for pouring a liquid, for example wine, from a container such as a bottle into a recipient such as a glass including a neck part which is configured to fit on an opening of the container, for example on a bottle neck; a pouring tube in fluid connection with a liquid channel of said neck part; an air tube in fluid connection with an air channel of said neck part, arranged to extend into the container for letting air into and out of the container.

Abstract: The invention relates to a container for cooling at least substantially cylindrical objects, in which the container is provided with at least two cooling walls, each connected to the other in an annular lower sides, each having an outside wall and two side edges extending from the lower side to an upper part of the wall, the side edges of adjacent cooling walls tapering towards each other from the upper part to the lower side, and an accommodation chamber being formed in each cooling wall for accommodation of a removable cooling element, which accommodation chamber is bounded by a part of a substantially circular bottom contour, the outside wall and the side edges.

Abstract: Cutting device provided with a curved bottom surface having a predetermined radius of curvature, provided with a front part, a rear part and with at least one longitudinal edge, as well as a cutting blade which is arranged transversely on the bottom surface and which extends at a distance from the longitudinal edge, in a longitudinal direction from the front part to the rear part and is connected to the bottom surface, which front part of the bottom surface is narrower in a transverse direction than the rear part, with a cutting edge extending in the longitudinal direction from a front point of contact with the bottom surface to a top which is situated at a distance from the bottom surface, which distance is at least 50% of the radius of curvature, preferably at least 75% of the radius of curvature, most preferably is at least virtually as great as the radius of curvature, and with an angle between the cutting edge and the bottom surface in the front point of contact being between 65° and 40°.

Abstract: A device and method for removing the core of a plant. This device consists of a tubular part which does not form a completely round circle, but only extends over approximately 180° (i.e. semi-circular arch). This tubular part is provided with a cutting section at one free end, thus making it possible to remove a core part of a plant. On the opposite end, the device is provided with a cutting section which does form a complete continuous circle, thus making it possible to remove an entire core of a plant such as lettuce.

Abstract: Pump for applying an increased or reduced pressure to a container. The pump is provided with a plate-like part which reacts to the pressure difference between the container and the environment. This part can preferably adopt two stable positions, and a change is signalled. This change can be brought about, for example, by the sound generated as a result of the plate-like part turning over. The pitch and the like of the sound can be influenced by arranging the plate-like part in a hollow piston and providing the latter with openings leading to the environment.

Abstract: Foil cutting device for cutting a sealing foil of a bottle. This foil cutting device is of the type which is positioned from above on the bottle. To that end a cutting device is provided with a stop determining the distance between the free extremity of the bottle and the cutting knives. The foil cutting device comprises two side portions and an upper portion connecting the side portions being integral with the side portions. In this way and elastically pivoting structure results, such that foil material can be cut with a lot of feeling. Between the side portions an opening is delimited and on one of the side portions a cavity for fingers is provided so that it is clear for the user in which direction a pinching force should be exerted for cutting the foil. The cutting knives are conically flared to a plane embodied such that after cutting the resilient foil material is run up by the cutting knives and can easily be removed.

Abstract: Pourer consisting of an elongated, tubular part of plastic material. This part of plastic material is made resilient and has an external diameter greater than that of the associated bottles. The tubular part is provided with a split, as a result of which the diameter can be reduced to some extent and the pourer can be accommodated with a clamping action in a bottle. This clamping can be even further promoted by providing ribs. The pourer is provided with a search point to facilitate introduction into a bottle and the pouring end is flared.

Abstract: Shut-off valve, composed of a container (3) provided with valve seat (4), and also a valve body (2, 22, 42) that can be moved through the opening bounded by the valve seat (4), in order to provide a seal. The valve body (2, 22, 42) is provided with a conical or spherical shut-off edge and is connected to the container (3) by way of a flexible connecting part (5). This makes it possible to move the valve body (2, 22, 42) laterally, in other words perpendicular to the direction of closing, and in this way achieve an opening of the shut-off valve. The container (3) can comprise any construction known in the prior art.
