The present invention relates to a lid for a cooking vessel, in particular, of a cooking pot.
For many dishes (e.g., roasts) that are prepared in a cooking vessel, it is important to prevent them from drying out during the cooking process. The closing of the cooking vessel with a lid makes it possible to limit the release of moisture into the environment. Moisture condenses at the underside of the lid and drops form. In the case of a curved lid, the condensate runs along the lid curvature, until it meets the edge of the lid. From there, it drips off or it moves downwards along the wall of the pot. In the case of slightly curved or flat lids, the condensate drips off randomly. In both cases, the food is wetted in an uncontrolled and irregular manner with regard to location and quantity of the condensate.
Thus, a need exists to overcome the problems with the prior art systems, designs, and processes as discussed above.
The invention provides a lid for a cooking vessel that overcomes the hereinafore-mentioned disadvantages of the heretofore-known devices and methods of this general type and that provide such features such that the condensate, which accumulates at the underside of the lid, drips onto the food to be distributed evenly.
With the foregoing and other objects in view, there is provided, in accordance with the invention, a lid for a cooking vessel includes a lid base having an edge and an underside with a plurality of shaped elements. Each of the plurality of shaped elements projects downwards from the underside, is flat or concavely curved, has a lowest location at which is a drip off edge, and respectively forms a planar lower surface that accumulates condensate, that is enclosed in a U-shaped manner, that slopes towards the edge of the lid, and that leads to the drip off edge. The lid can be a cooking pot lid.
According to the invention, this task is solved in that a plurality of shaped elements projects downwards at the underside of the lid, which is curved inwards, with said shaped elements in each case forming an in particular plane lower surface, which accumulates condensate and which is enclosed in a U-shaped manner and which slopes towards the edge of the lid and which leads to a drip off edge at its lowest location.
Such shaped elements can be distributed evenly across the underside of the lid such that the condensate, which forms from the water vapor at the underside of the lid, drips off so as to be distributed evenly across the food and thus wets the food evenly. The condensate thus no longer drips off from the underside of the lid in a disorganized manner and also no longer flows to the edge of the lid, so as to drip off at that location.
It is important hereby that the shaped elements and in particular the drip off edges and/or drip off tips thereof are distributed evenly across the lower surface of the lid.
The shaped elements either from surfaces, which project downwardly in a stepped manner or beads, which are curved in a U-shaped manner, which define the lower surfaces, which accumulates condensate.
An advantageous, particularly even distribution is attained when the shaped elements are arranged at equal intervals in rows on concentric circular rings. For this purpose, it is also proposed that all or at least the plurality of the shaped element encompass an equal, plane lower surface, which accumulates condensate. Preferably, it is proposed that the lower surface encompasses an incline of α=5 to 40 degrees.
In accordance with another feature of the invention, the shaped elements are distributed evenly about the underside of the lid.
In accordance with a further feature of the invention, the drip off edges of the shaped elements are distributed evenly about the underside of the lid.
In accordance with an added feature of the invention, the shaped elements are disposed at equal intervals in rows on concentric circular rings.
In accordance with an additional feature of the invention, the lower drip off edge of the shaped elements are located on concentric circles of the underside of the lid.
In accordance with yet another feature of the invention, the lid base has a center and the shaped elements have a wedge-shaped cross-section increasing from the center of the lid base radially outwards.
In accordance with yet a further feature of the invention, at least the plurality of the shaped elements form or border a lower surface of substantially equal size and the lower surface accumulates condensate.
In accordance with yet an added feature of the invention, the shaped elements are beads curved in a U-shaped and defining the lower surface that accumulates condensate.
In accordance with yet an additional feature of the invention, the beads encompass a substantially equal cross-section across their length.
In accordance with again another feature of the invention, the lower surface encompasses an incline of between approximately 5 degrees to approximately 40 degrees, in particular, between approximately 10 degrees to approximately 20 degrees.
In accordance with again a further feature of the invention, the lower surfaces of all of the shaped elements have the same angle of inclination or a different angle of inclination.
In accordance with again an added feature of the invention, the lower surfaces encompass the shape of at least one of a wedge, a circular sector, and a circular ring sector comprising an acute interior angle.
In accordance with again an additional feature of the invention, bisecting axes of one of the wedge-shaped lower surfaces and the circular sector-shaped lower surfaces are radially disposed.
In accordance with still another feature of the invention, the one of the wedge-shaped lower surfaces and the circular sector-shaped lower surfaces overlap one another.
In accordance with still a further feature of the invention, the lower surfaces have tips and the tips are covered by another of the lower surfaces located higher on the underside of the lid.
In accordance with a concomitant feature of the invention, the lid base is of cast iron, steel, glass, or a combination thereof. At least the underside of the lid can have an enamel layer.

As used herein, the term “about” or “approximately” applies to all numeric values, whether or not explicitly indicated. These terms generally refer to a range of numbers that one of skill in the art would consider equivalent to the recited values (i.e., having the same function or result). In many instances these terms may include numbers that are rounded to the nearest significant figure.
Herein various embodiments of the present invention are described. In many of the different embodiments, features are similar. Therefore, to avoid redundancy, repetitive description of these similar features may not be made in some circumstances. It shall be understood, however, that description of a first-appearing feature applies to the later described similar feature and each respective description, therefore, is to be incorporated therein without such repetition.
Described now are exemplary embodiments of the present invention. Referring now to the figures of the drawings in detail and first, particularly to
To prevent this, a plurality of shaped elements 5a, which project downwards and which respectively encompass a lower surface 6, which is planar but which slopes towards the edge of the lid 1, on its underside, is integrally molded to the underside 2 of the lid 1 in accordance with
In the exemplary embodiment of the lid illustrated in
In addition, the shaped elements 5a, 5b, which are disposed radially and in a stepped manner, are configured so that the lower surfaces 6 thereof are distributed evenly across the underside 2 of the lid 2. On the lower end, and thus at its lowest positions, each lower surface or the base of the U-shape, respectively, has a drip off edge 7 or one or a plurality of drip off tips, towards which the droplets of a lower surface run, so as to drip onto the food as large drops at that location. The radial intervals of the drip off edges 7 and/or drip off tips from one another are thus equal. These measures ensure that the condensate drips onto the food in a way that is distributed evenly locally.
The shaped elements 5a, 5b are located on circular rings, which are concentric to one another and into which the underside 2 of the lid is divided, so that the lower surfaces 6 divide the circular rings to be located closely to one another. Only narrow, radial, groove-shaped gaps 9 remain between the shaped elements. Through this, the innermost or central lower surfaces 6, respectively, have the shape of a circular sector and the remaining lower surfaces 6, which divide the circular rings, have the shape of circular ring sectors. In both cases, the two outer radial side edges 5c, 5d of the shaped elements 5a or of the lower surfaces 6, respectively, together form an acute interior angle β (see, e.g.,
Instead of the shapes of the lower surfaces 6 illustrated in the figures and, thus, of the shaped elements 5a, 5b, the underside 2 of the lid can also be divided in a different manner into individual, non-illustrated shaped elements or lower surfaces, respectively, which are shaped differently, whereby it is ensured that all of the lower surfaces are substantially equal and have an angle of inclination a that is substantially equal or increases towards the edge of the lid 1 and a drip off edge and/or at least one drip off tip at its lowest position. It is also advantageous, if the lower drip off edges 7 of the shaped elements are located on concentric circles of the underside of the lid 1.
The lid 1 can be of steel or glass, for example, and, in particular, of cast iron. In an exemplary embodiment, at least the underside of the lid 1 is provided with an enamel layer.
Two further embodiments of the underside of the lid 1 according to the invention are illustrated in
