DE102023116831A1 - Lid, especially for a frying or cooking vessel - Google Patents

Abstract

The present invention shows a lid for a frying or cooking vessel with a circular ring, a disk and a shape-changing unit arranged between the circular ring and the disk and connecting the circular ring and the disk to one another.

Description

The present invention relates to a lid, in particular for a frying or cooking vessel, with the features of patent claim 1.

background

In the kitchen, liquids are often heated in a cooking or frying pan. When heating liquids such as milk or liquids containing protein, if these liquids are heated to a high temperature, they often foam up and their volume increases almost instantly, causing the liquids to boil over and spill over the top of the cooking or frying pan.

It is also known that when heating liquids in the kitchen, a large part of the energy used escapes from the top of the cooking or frying vessel if there is no lid on the cooking or frying vessel. Therefore, in order to save energy, it is advisable to always use a cooking or frying vessel with a lid.

However, if only a small amount of liquid is to be heated in a cooking or frying vessel, even if a lid is placed on the cooking or frying vessel, the volume of air in the cooking or frying vessel between the surface of the liquid and the lid will also be heated, although this is not necessary.

State of the art

From the WO 2001/06902 Gastronorm containers according to DIN 66075 are known, with a base and side walls, wherein the height and/or the width of the side walls (2) lying opposite one another in pairs can be jointly set and varied, and/or the width and/or the depth of the base (1) can be varied accordingly.

From the DE 20 2016 106 572 U1 A foldable pot made of silicone with a pot body is known, wherein the pot body has a heat-conducting base, an annular silicone wall, and a frame, wherein the lower part of the annular silicone wall is firmly connected to the heat-conducting base and the frame is firmly connected to the upper part of the annular silicone wall.

From the EP 2 324 739 A1 is a cooking vessel attachment for preventing liquids from boiling over, in particular liquids that foam up when cooked and have a high protein or starch content, such as milk, cooking water from potatoes or pasta, or the like, which is designed as a collecting bowl and has at least one opening for the liquid to pass through. At least one flat closure part is assigned to the opening or openings, which is connected to the cooking vessel attachment.

Task

It is now the object of the present invention to show a possibility of reducing the volume in a cooking or frying vessel between the liquid present in the cooking or frying vessel that is to be heated and the volume of the cooking or frying vessel, so that only a remaining small volume of air in the cooking or frying vessel has to be heated and at the same time to prevent the liquid from boiling over when heating in the cooking or frying vessel.

Solution

This object is achieved by means of the features of patent claim 1.

The invention shows a lid for a cooking or frying vessel, wherein the lid consists of at least one circular ring, one disk and a shape-changing unit arranged between the circular ring and the disk and connecting the circular ring and the disk to one another. By means of the shape-changing unit, the distance between the circular ring and the disk can be changed, at least between a first distance between the circular ring and the disk, which represents the starting position between the circular ring and the disk, and a second distance between the circular ring and the disk, which represents the final deflection position between the circular ring and the disk.

The lid is intended for covering an opening of a cooking or frying vessel. The lid is round in a cylindrical cooking or frying vessel and has a circular ring with which the lid is placed on the edge of the cooking or frying vessel. The disc arranged below the circular ring, which is connected to the circular ring via the shape-changing unit, is slightly smaller in diameter than the diameter of the cooking or frying vessel and can engage in the cooking or frying vessel. Since the disc below the circular ring is connected via the shape-changing unit, it reaches a little "deeper" into the cooking or frying vessel. The distance between the circular ring and the disc can now be changed so that the circular ring penetrates deeper into the cooking or frying vessel. In the final deflection position, the circular ring and the disc, connected via the shape-changing unit, are adjustable unit, arranged in the position furthest apart from each other. In this case, the disc penetrates the deepest into the cooking or frying vessel. If a liquid is to be heated in the cooking or frying vessel, the distance between the circular ring and the disc can be selected so that when the circular ring rests on the cooking or frying vessel, the distance between the surface of the liquid and the disc is small. This minimizes the volume of air between the disc and the surface of the liquid and energy losses when heating the liquid are minimized.

In the initial position, the distance between the circular ring and the disc is minimized, so that when the lid is stowed away, it has only a smaller volume.

Furthermore, the diameter of the discs is smaller than the diameter of the circular ring and the diameter of the circular ring, otherwise it could not be inserted into a cooking or frying vessel.

Since the diameter of the discs is slightly smaller than the diameter of the cooking or frying vessel, a gap remains between the side wall of the cooking or frying vessel and the disc. If the liquid in the cooking or frying vessel foams up when it is heated, the disc prevents further foaming beyond the edge of the disc, just as if a wooden spoon were placed on the edge of the cooking or frying vessel or were placed in the cooking or frying vessel, whereby the wooden spoon, preferably made of metal, must reach out of the liquid.

In an advantageous embodiment of the invention according to claim 2, it is provided that both in the starting position and in the final deflection position, the distance between the circular ring and the disk is almost the same all the way around, perpendicularly between the disk and the circular ring. This ensures that the disk is arranged almost level with the bottom of the cooking or frying vessel in the cooking or frying vessel.

In an advantageous embodiment of the invention according to claim 3, it is provided that between the starting position and the final deflection position, further distances can be taken between the disk and the circular ring. This allows the depth of penetration of the disk into the cooking or frying vessel to be varied.

In an advantageous embodiment of the invention according to claim 4, the shape-changing unit is made of silicone or plastic. The shape-changing unit can thus be easily cleaned, is temperature-resistant and has a smooth surface. The shape-changing unit can be folded up and pulled apart between the starting position and the end deflection position of the lid.

In an advantageous embodiment of the invention according to claim 5, it is provided that the shape-changing unit is connected to the circular ring on the side of the circular ring and approximately in the middle of the circular ring, and the connecting surface between the circular ring and the shape-changing unit has a circular ring shape and the shape-changing unit is connected to the disk on the side of the disk opposite the circular ring, wherein the connection between the shape-changing unit and the disk forms a further circular ring shape. The shape-changing unit thus forms a mechanical connection to both the disk and the circular ring, which creates an even distribution of force in the ring and the disks. In addition, the connection between the shape-changing unit and the disk and to the circular ring is formed by a further circular ring shape and forms a gas-, vapor- and/or liquid-tight transition.

In an advantageous embodiment of the invention according to claim 6, it is provided that the connection between the shape-changing unit and the circular ring, as well as the connection between the shape-changing unit and the disc, is an adhesive connection. A silicone-based adhesive can be used here which is heat-resistant and UV-light-resistant, so that a firm and resilient connection is formed between the shape-changing unit and the disc or the circular ring.

In an advantageous embodiment of the invention according to claim 7, the circular ring is made of plastic or silicone and the disc is made of glass or transparent plastic. Choosing a disc made of glass or transparent plastic ensures that the liquid in the cooking or frying vessel is visible. In addition, both glass and plastic can be easily bonded with silicone, ensuring that the connection between the shape-changing unit and the circular ring and the disc is stable and force-fitting and thus adheres well to one another.

In an advantageous embodiment of the invention according to claim 8, it is provided that the shape-changing unit forms a lateral surface between the circular ring and the disk, wherein in the final deflection position the lateral surface is tensioned and in the initial position the man surface is folded or collapsed. This means that the lid can be easily stowed away in the starting position, as it takes up little volume. In the final deflection position, the outer surface is tensioned and can therefore be cleaned easily. In addition, the lid is stable in its final deflection position in its designed shape, as the material tension of the shape-changing unit in the final deflection position keeps the circular ring and the disk spaced apart from each other.

In a further advantageous embodiment of the invention, material thickenings are incorporated in the lateral surface, which extend from the disk to the circular ring at equidistant intervals from one another and/or run parallel to the circular ring around the lateral surface at equidistant intervals from one another.

In an advantageous embodiment of the invention according to claim 9, it is provided that the outer surface of the shape-changing unit has a material thickness of one to five millimeters. This choice of material thickness makes the outer surface durable and provides a sufficiently stable connection between the disks and the circular ring.

In an advantageous embodiment of the invention according to claim 10, it is provided that the outer surface forms a hollow cylindrical shape and the outer surface is closed. The hollow cylindrical shape ensures sufficient stability. The closed outer surface, i.e. no breakthroughs or openings in the outer surface, prevents liquid or other material from penetrating through the outer surface of the shape-changing unit during cooking. In addition, it is alternatively provided that the outer surface tapers in cross-section from the circular ring to the disc. This means that when folded, the outer surface can be folded together next to each other and there is no thickening of the material.

In an advantageous embodiment of the invention according to claim 11, a handle is arranged on the side of the circular ring facing away from the disc. This allows the lid to be easily handled.

In a further advantageous embodiment of the invention, it is provided that the handle is designed as an arc that spans the circular ring and is connected to the circular ring on two opposite sides. In a further advantageous embodiment of the invention, the handle is arranged via bearing points in the connection area between the circular ring and the handle and is designed to be pivotable.

In an advantageous embodiment of the invention according to claim 12, it is provided that the circular ring has a circular ring width of between one cm and seven cm. This choice of dimensions ensures the required stability of the circular ring and at the same time sufficient surface area to connect the handle to the circular ring.

In an advantageous embodiment of the invention according to claim 13, the circular ring has a surface with circumferential indentations. This ensures that the circular ring does not simply slip when placed on the edge of a cooking or frying vessel, since the circumferential indentations or depressions partially enclose the edge of the cooking or frying vessel.

In an advantageous embodiment of the invention according to claim 14, it is provided that the diameter of the circular ring is larger than the diameter of the disk. This is necessary so that the disk of the lid can be inserted into the cooking or frying vessel and the circular ring rests on the edge of the cooking or frying vessel.

According to claim 15, a cooking or frying vessel with a lid is described, which takes up at least one feature of the previous claims 1 to 14 and the diameter of the cooking or frying vessel is smaller than the diameter of the circular ring of the lid and the diameter of the disc is smaller than the diameter of the cooking or frying vessel. Further advantages, features and design options can be found in the following description of figures of non-limiting embodiments.

Detailed description of implementation examples

In 1 a perspective view of a lid according to the invention is shown.

The lid 1 consists of a ring 2, on the top of which a handle 6 is arranged.

Below the ring 2 is a shape-changing unit, in the design according to 1 as a foldable silicone body 4. The foldable silicone body 4 is glued to the underside of the ring 2 and is thus firmly connected to the ring 2.

The foldable silicone body 4 is in 1 folded up.

On the side of the foldable silicone body 4 opposite the ring 2, the latter is glued to a disc 3 and thus firmly connected to it.

On the ring 2, a handle 7 is formed opposite each other.

In 2 a further schematic representation of a lid according to the invention is shown.

The cover 1 consists of a ring 2, which in the embodiment according to 2 is a circular ring.

An annulus is the area between two concentric circles, i.e. between two circles with a common center.

A handle 6 is arranged on the top of the ring 2, which extends from one side of the ring 2 to the other side and spans the ring 2 in an arc shape. The handle 6 can be pivoted about the center axis of the ring 2.

Below the ring 2 is a shape-changing unit, in the design according to 1 as a foldable silicone body 4. The foldable silicone body 4 is glued to the underside of the ring 2 and is thus firmly connected to the ring 2.

On the side of the foldable silicone body 4 opposite the ring 2, the latter is glued to a disc 3 and thus firmly connected to it.

A disk is a geometric body in the shape of a cylinder whose radius is many times higher than its thickness.

The foldable silicone body 4 can be moved by exerting a force on the foldable silicone body 4 from an initial position in which the ring 2 and the disc 3 are relatively close to each other and the foldable silicone body 4 is arranged folded between the ring 2 and the disc 3, to an end position in which the foldable silicone body 4 is completely unfolded and the disc 3 is arranged relatively far apart from the ring 2, as in 1 shown.

In the unfolded state, the foldable silicone body 4 forms a jacket surface 5 between the ring 2 and the disc 3, which in the embodiment according to 1 takes on a truncated cone-like, hollow shape. The base surface of the truncated cone is formed on the ring 2 and the top surface of the truncated cone is formed on the disk 3.

The distance between the ring 2 and the disc 3 is almost the same in both the starting position and the end position. If you look all the way around the contact surface of the foldable silicone body 4 with the ring 2 and measure the distance to the disc 3 perpendicularly, this distance is always almost the same.

It is now possible to vary the distance between the ring 2 and the disc 3 between the starting position and the end position, so that various distances between the disc 3 and the ring 2 can be achieved.

This is advantageous because the lid 1 is placed on a - in 1 pot (not shown), with the ring 2 resting with its underside on the edge of the pot and the disc 3 protruding into the pot. Depending on the dimensions of the foldable silicone body 4, the lid 1 can be adjusted to different pot heights.

The lid 1 serves on the one hand to reduce the volume of air in a pot between the food in the pot and the food to be heated, thus allowing only a reduced volume to be heated and on the other hand to prevent boiling over, as the disc in the pot prevents foaming liquids in the Pot and at the same time prevents foaming. To do this, the disc 3 should be smaller in diameter than the pot diameter so that steam and the foaming liquid that forms is forced between the disc 3 and the edge of the pot and flows out. This prevents foaming.

By means of the foldable silicone body 4, the penetration depth of the disc 3 can now be adapted to a pot by adjusting the distance between the ring 2 and the disc 3 to the fill level of the pot by means of the foldable silicone body 4.

The ring 2 is preferably made of plastic and has ring-like indentations or grooves running around its surface. These are used to place the ring on the edge of a pot, with the edge of the pot lying in the grooves. This enables the ring 2 and thus the lid 1 to be held relatively securely and firmly on the pot.

The pane 2 is made of transparent and temperature-resistant plastic or glass. This is advantageous because you can still see into the pot and see the food heating up in the pot even when the lid 1 is on.

The outer surface 5 is made entirely of silicone and has no perforations. The thickness of the outer surface 5 and thus of the foldable silicone body 4 is preferably selected to be between one millimeter and seven millimeters and is almost the same across the entire outer surface 5.

The ring 2 preferably has a ring width of one to seven centimeters.

On the ring 2, a handle 7 is formed opposite each other.

The diameter of the ring 2 and the disc 3 and thus the size of the lid 1 is adapted to the pot with which the lid 1 is to be used. If the lid is to be used with a pot with a diameter of twenty centimetres, the diameter of the ring 2 should be between twenty-two and twenty-five centimetres, while the diameter of the disc should be a maximum of nineteen centimetres.

In 3 a side view of a lid according to the invention is shown.

The lid 1 in turn has a ring 2, on the upper side of which a handle 6 is arranged.

A foldable silicone body 4 is arranged beneath the ring 2 and is shown in its folded position. The foldable silicone body 4 is glued to the underside of the ring 2 and is thus firmly connected to the ring 2.

On the side of the foldable silicone body 4 opposite the ring 2, the latter is glued to a disc 3 and thus firmly connected to it.

The lateral surface 5 is shown in folded form.

On the ring 2, a handle 7 is formed opposite each other.

In 4 another side view of a lid according to the invention is shown.

The lid 1 in turn has a ring 2, on the upper side of which a handle 6 is arranged.

A foldable silicone body 4 is arranged beneath the ring 2 and is shown in its unfolded or opened position. The foldable silicone body 4 is glued to the underside of the ring 2 and is thus firmly connected to the ring 2.

On the side of the foldable silicone body 4 opposite the ring 2, the latter is glued to a disc 3 and thus firmly connected to it.

On the ring 2, a handle 7 is formed opposite each other.

The outer surface 5 of the foldable silicone body 4 is shown in unfolded form. In the embodiment according to 4 the outer surface 5 is provided with steps so that the foldable silicone body 4 can be easily folded up and the foldable silicone body 4 fits between the ring 2 and the disc 3.

In 5 is a perspective view of a lid according to the invention placed on a pot.

The lid 1 with the ring 2 is shown and the ring 2 rests on the edge of the pot 8.

On the ring 2, a handle 7 is formed opposite each other.

The foldable silicone body 4 is folded together and the disc 3 is arranged on the foldable silicone body 4. The lid 1 with the foldable silicone body 4 and the disc 3 extends a small distance into the pot 8.

In 6 is a further perspective view of a lid according to the invention, placed on a pot.

Again, the lid 1 is shown with the ring 2 and the ring 2 rests on the edge of the pot 8.

On the ring 2, a handle 7 is formed opposite each other.

The foldable silicone body 4 is unfolded and the disc 3 is arranged on the foldable silicone body 4, which, however, is shown in the illustration according to 6 extends so far into the pot 8 that it is no longer visible. The lid 1 with the foldable silicone body 4 and the disc 3 now reaches almost to the bottom of the pot 8.

Although the invention has been illustrated and described in detail by the advantageous embodiments, the invention is not limited by the disclosed examples. Other variations can be derived from this by the person skilled in the art without departing from the scope of the invention. In particular, the invention is not limited to the combinations of features specified below, but other combinations and partial combinations that are obvious to the person skilled in the art can also be formed from the disclosed features.
