Description

The The invention relates to a cooling lid, consisting of a Hard and soft plastic component for leakproof sealing of containers and simultaneous cooling of liquid and solid substances, especially foods. At the cooling lid is a high-quality, professional cooling and insulation system for closing various harnesses or containers, which with the special, inventive Lid can be closed leak-proof and their contents to be cooled.

systems of this type, in particular those which are closed by lids can, are in numerous variants from the daily Domestic use and commercial use in the food industry. and catering. In most cases becomes the vessel the food absorbs should, closed by a lid or a kind of lid, the made of the same material as the food or beverage receptors Container is made and usually consists of plastic, but neither a keep warm, nor a cooling guarantee can.

It are basically two variants of use to distinguish. One variant relates to food containers, the to serve food or drinks and temporarily, at short notice to cool and those directly after their manufacture, z. As canned food, for a longer storage are suitable for storage, but no cooling of the Container inside the container is necessary So stored in cold rooms or the like become.

at the use variant of the invention, the here is present, the container with solid and / or liquid Substances, preferably solid and / or liquid foods filled and then closed with a lid to this to store at short notice, if necessary to transport and, in particular, over to keep cool for a certain period of time. This variant is mainly used in commercial kitchens, in the hotel and catering industry, Retirement homes, hospitals, homes for the disabled or other public Facilities or used in private households. Such containers with cover should be reusable after proper cleaning and be used for cooling, but also in use, close the container holding the food tightly and, above all, cool. The cooling unit should be regenerable be, d. H. by inserting in the freezer or another, commercially available Cooling unit regenerable, so unlimited cooling down be, thus for the consumer a durable use is possible. It's supposed to be the principle of a commercial one Cooling batteries are based.

The closest prior art to this invention is the German utility model publication G 94 10 392.5 that has expired in the meantime. From this document a harness with integrable or integrated freezing insert in the lid is known. The system is made of plastic and is known for cooling and storing food. As a rule, this system describes a vessel or a lid which can accommodate a separate cooling element. It consists of a uniform material and can only be used for one vessel. Furthermore, the lid does not have a sealing ring with snap edge and does not consist of two different plastics such as the present invention, so that a leak-proof and airtight sealing, is not guaranteed with simultaneous cooling.

The present invention therefore an object of the invention to provide a cooling lid, which is suitable for leak-proof closing of containers and simultaneous cooling of liquid and solid materials, wherein the cooling cover a sealing ring with snap edge ( 1 ), consisting of a plastic soft components, which surrounds a harder plastic, which is filled with a regenerable coolant and permanently closed, so does not possess the disadvantages of the prior art and meets the requirements indicated.

The present invention now relates to a cooling lid, consisting of a hard and soft plastic component for leakproof closing of a variety of containers and simultaneous cooling of liquid and solid materials, in particular food in liquid and solid form. The cooling lid is characterized in particular in that the lid in the edge region, which is placed on the edge of the container to be closed, a sealing ring with snap edge ( 1 ) of a plastic soft component having a plastic hard component ( 2 ), wherein the internal hard plastic component ( 2 ) after being filled with a regenerable coolant with a cover ( 3 ), which also consists of a hard plastic, is permanently welded. For clarity, it must be noted that the upper and lower sides of the inner plastic hard component ( 2 ) is usually not surrounded by the plastic soft component, so is exposed. Thus, the plastic hard component that receives the coolant, unhindered radiate the cold in the interior of the vessel where the substances to be cooled are. Optionally, towards the outside, ie in the area of the cover ( 3 ), insulation or the cover ( 3 ) even from good insulating material who elected so that the cold is delivered primarily to the inside of the food container.

The lid edge is therefore made of soft plastic and has a sealing ring with snap edge ( 1 ) and sealing lip ( 4 ) on. This is particularly clear from the drawing 2, which shows a partial view of the cooling cover in the side area, clearly visible.

The Invention also relates to a cooling lid, which by a container to be closed has completely surrounding sealing ring with snap edge, which is so elastic that the manufacturing tolerances of the to be closed Container can be compensated in the sealing edge. hereby become the described disadvantages of the pure plastic container avoided food intake and acceptance of the food Containers when used directly as serving or eating utensils reached.

porcelain is the most accepted material in this regard, however at the same time the most difficult to seal tightly, because it is production-wise not plan and relatively large Manufacturing tolerances in mass production has. The porcelain containers can not yet or only insufficiently be sealed tightly. These hitherto known and described Arrangements, so the combination of container and lid but have the disadvantage that they due to the Porcelain, due to the manufacturing process, relatively large Dimensional tolerances never completely tight with a standard cover can be closed and the lid can not be cooled are. Porcelain is basically not plan and therefore can in the traditional way, as with pure plastic containers is known, not be sealed. A tight final Lid or closure needs these deviations of dimensions compensate.

Another object of the present invention is therefore that the cooling cover can also be easily placed on porcelain dishes, earthenware or glass, so on solid, not made of plastic, other materials. This is essentially due to the fact that the cooling cover by the outside, in the edge region lying plastic soft component in the form of a sealing ring with snap edge ( 1 ) also a sealing lip ( 4 ), which conforms to the vessel to be closed in its edge region and thus can close the container air and leak-proof.

Of the Cooling cover is so in its edge area by the selected Soft plastic component elastic and thus can the possible Manufacturing tolerances of the container to be sealed in Balance the sealing edge of the cover.

The Most plastic containers are relatively good with lids or to close closures, with the lids or closures but also made of plastic are and have no cooling function. Such containers are also unsuitable for directing the food in it to serve. The acceptance of the consumer, directly from the plastic container to absorb the chilled food contained therein is low and especially in the hotel and restaurant industry, but also in commercial kitchens, nursing homes, hospitals, when eating on wheels, so food-making services or other public facilities as well as in private Households, due to lack of consumer acceptance and missing Hygiene rejected. The result is that one is forced to eat the food, to refill after cooling into other dishes. As a result, an unacceptable loss of cold in the Food evoked. In addition, the method is time-consuming and costly, destroys partly already during the production and packaging the food agent noticed appealing design (decoration) and means especially in the commercial, public Use, an economically unreasonable extra effort by necessary additional staff, additional pollution of crockery and associated higher energy costs by necessary cleaning of additional dishes and higher Capacity in flushing devices and larger Tableware storage.

It is therefore desirable to fill the food and drinks for transport and / or storage directly into containers that are immediately suitable for serving and no cumbersome decanting required, but can also be sealed and cooled over the cooling lid. The type of material of the cooling lid for closing the food container is not critical in terms of consumer acceptance. However, the inventive design of the cooling lid requires the combination of at least two different plastics, ie at least one soft plastic component with a hard plastic component, wherein the lid edge, ie the position where the cover the sealing ring with snap edge ( 1 ), always consists of a soft plastic and the inner region, ie where the lid has the cavity, which is filled with the coolant, usually consists of a plastic hard components.

It is not critical, which plastics are used.

The cooling cover is preferably designed so that the inner area is designed like a small container that can be filled with the coolant. After filling with a Kühlmit tel is the cavity containing the coolant, which consists of a plastic hard component ( 2 ) is made with a usually made of the same material cover ( 3 ) permanently welded by ultrasound. This happens before the first use and can only be reopened by destroying the lid. The selected cooling component is also not critical. Here you can use any commercially available coolant, which is approved in the food sector. In special cases, where other substances not intended for consumption are to be cooled, it is also possible to use other suitable coolants. The lid is preferably made of food-safe plastics which are dishwasher-safe, heat-resistant and, in particular, cold-resistant. The nature of the materials is not critical here. Furthermore, every imaginable shape of the lid is possible. But are preferred circular, rectangular or oval shapes.
