Definitions

• the invention relates to a kitchen appliance, in particular one which can be used as a fresh-food lid, as a microwave lid and as a coaster.
• food containers which consist of a container part and a lid, wherein in the container part with the lid, a negative pressure can be generated, which helps to keep fresh food contained in the food container longer.
• DE 82 27 597 U1 describes a vacuum storage container for easily perishable goods.
• a manually operable air pump is integrated in the lid. When the lid is attached, the user can create a negative pressure in the container by repeatedly pressing the lid.
• This known container has the disadvantage that on the one hand a structurally complicated lid is required, which can only be produced with correspondingly high costs. This lid is also difficult to clean, which is particularly detrimental to kitchen utensils that come into contact with perishable foods. Finally, both hands must be used to operate the pump mechanism because one hand must hold the container and the other hand must depress the lid ,
• the lid can be used only with a container part adapted exactly to its shape. Furthermore, the construction of the lid is difficult, because its deformation behavior must be exactly the same, that even when the lid is turned up its convex shape remains stable, although there is a negative pressure in the interior. Finally, the everting in the edge region of the lid represents a considerable mechanical alternating load, so that it can not be ruled out that the lid breaks there after a relatively short period of use.
• lids are known, which are placed as a hood on a vessel in which a food is to be heated in a microwave oven. Since this warming takes place very quickly and the food can splash it, the lid is required to protect the interior of the microwave oven against such splashes, such as fat splashes. On the other hand, the lid must not close the container tightly, because the lid could be blown off as a result of the rapid warming, if quickly set in the vessel overpressure.
• Known microwave lid therefore have holes in the upper region, which cause a pressure equalization. Through these holes but can leak fat splashes.
• coasters which serve to protect this, a sensitive surface, for example a wooden surface of a kitchen or dining table against contamination, especially against Sengpatentedden when a hot pot or a hot pan on this surface is discontinued.
• Known coasters therefore consist of a heat-insulating material (wood, plastic, fabric) and are plate-like.
• the known devices have in common that they are only usable for their own purpose.
• the lid used in each case can only be used as a lid for a particular container part.
• the invention is therefore the object of developing a kitchen appliance of the type mentioned in such a way that a versatile equipment is provided, which is also superior in their respective field of application conventional equipment this application area.
• this object is achieved in that the kitchen appliance has a disc-shaped body, which is formed reinforced in the middle region as a stretched, elastic film and the edge.
• the object underlying the invention is completely solved in this surprisingly simple manner.
• the kitchen utensil when the kitchen utensil is placed on the edge of a container part of a fresh food container, it is sufficient to slightly depress the kitchen equipment in the middle region in order to effect a long-term effective closure of the container part.
• the stretched film acts as a membrane which displaces air from the container part when pressed in and generates a negative pressure in the container part during the elastic retraction. This negative pressure holds, as experiments have shown, over several days and is also mechanically strong.
• the handling of the kitchen utensils is extremely simple, because the user of the kitchen equipment with one hand on the container part hang up and then with the same hand can depress the foil.
• the container part needs, unlike the above-discussed prior art, while not being held with the other hand.
• the kitchen utensil according to the invention can be used for food containers, bowls and the like in order to prevent premature spoiling, in particular of sensitive foods such as salads, sauces, ice cream and the like.
• the kitchen utensil can also be used as a protective cover to prevent inadvertent spillage of, for example, liquid contents of food containers prevent.
• kitchen equipment according to the invention can be used advantageously as a cover on a beer mug when it is brought from the bar to a table in a restaurant, which are in the case of a beer garden or a marquee at a considerable distance can.
• a waiter carries several beer steins at the same time, it can come in particular in the scrum that beer is spilled on the clothes of guests. With the kitchen appliance according to the invention, this can be reliably prevented.
• the kitchen utensil adheres so firmly to the filled beer mug that, as stated in the aforementioned experiments, it can even be turned upside down without beer running out.
• the kitchen appliance according to the invention can also be used as a microwave lid. Then it is advantageous that the loosely placed microwave lid on the one hand allows pressure equalization between the interior of the microwave vessel and its outer space, on the other hand, no ejection is possible by the closed surface of the film. This is especially true when the kitchen equipment is provided with certain other preferred features. The same applies to their use as coasters. These other uses will be discussed below
• the kitchen appliance according to the invention can be designed differently. It is preferred if they are in the floor plan is formed circular disk-shaped or oval-shaped or rectangular.
• This measure has the advantage that the kitchen utensil can be optimally designed depending on the case of use.
• the edge is integral with the film.
• This measure has the advantage that the kitchen appliance can be produced in a simple manner by casting, in particular by injection molding.
• a particularly good effect is achieved in that the film is smooth on a surface.
• This measure has the advantage that, when used as a freshness-keeping lid, the negative pressure in the container part can be maintained long-term, when the smooth surface fits snugly against the edge of the container part.
• silicone is available that is food safe. Furthermore, silicone equipment with smooth, almost tacky surfaces can be made. Finally, silicone is temperature resistant to about 25O 0 C. temperature resistant and heat insulating, which is in the use case as a coaster of importance.
• the film has a thickness of 0.5 to 2 mm, preferably from 1 to 1.5 mm.
• the film is provided with a reinforcement at the center of the central region.
• This measure has the advantage in the use case as Frischhaltedeck ⁇ l that the mechanically stressed point when pressing down is reinforced, so there is no need to fear the occurrence of damage due to breakage of the film due to continuous forming.
• the gain is designed as a thickening of the film.
• the edge is reinforced by an injected metallic reinforcing element, in particular by a ring.
• an injected metallic reinforcing element in particular by a ring.
• the edge has a height which is substantially 2 to 6 times, preferably 4 to 5 times as large as the thickness of the film.
• this measure has the advantage that there is enough space in the edge to accommodate a reinforcing element there.
• the hot pot with its bottom is at a distance from the sensitive surface, e.g. the dining table is held, wherein the air cushion between the bottom and the surface in addition to the film has a heat insulating effect.
• the margin is as high as the gain.
• This measure has the advantage in the case of use as a coaster, that the bottom of the pot is supported in the center, so that the weight load not only rests on the edge.
• Another group of embodiments of the invention is characterized in that the film is provided on a surface with a plurality of ribs extending from the edge towards a center of the kitchen utensil.
• This measure has the advantage, in particular in the case of use as a microwave lid, that an even more effective pressure equalization between the interior of the microwave vessel and its outer space is possible through the interstices between the ribs, without the covering effect of the film suffering as a result of the pressure equalization on the underside the lid takes place.
• the ribs have a length that is substantially half the distance of the rim from the center. Furthermore, the ribs preferably have a height that is smaller than a height of the rim.
