The invention relates to a container for the preparation of j Food with supply of heat, in particular as a household and kitchen appliance / with a temperature display that can be read visually from the outside, ι

Containers of the generic type mentioned in the introduction are known, |

which have an eccentrically arranged passage in the region of the j

Have lid of the container through which passage a j

Liquid thermometer protruding into the interior of the container; is importable. With such containers it is a disadvantage

that when using the container without a thermometer for the Ab- '

Closure of the passage in the lid a special closure er j

is required if the container is not used! restricts: should be. In addition, they come from a glass flask with

Glass capillary and the liquid absorbed in it! Liquid thermometers are easily damaged and generally bulky.

The invention is therefore aimed at promoting the purpose of a '· container for the preparation of food with the supply of heat by means of a space-saving temperature display which is largely insensitive to the usual stresses that occur in particular in the home and kitchen.

This is achieved by arranging an indicator, which changes color to indicate temperature, as a temperature display on the container is.

By such, for example on a part of the outer wall the paintable indicator on the container or the lid, but preferably on or in a foil, sheet or tabular support is added (see claim 21, is a space-saving, practically hardly outstanding on the wall surface or protruding temperature display. At this temperature display is - if necessary made clear by correspondingly clear symbols - visually readable when the for the treatment process the desired temperature of the food to be prepared has been reached in the container. - 4 _

The further development according to claim 3, preferably in conjunction with that according to claim 4 and / or set, provides a simple and also easily perceptible from a greater distance - because the indicator can be seen from above. Even with close thermal contact between the indicator and the wall of the container, pot or lid, the temperature displayed by the indicator is not identical to the temperature of the goods in the container, but is lower than this and only has a certain relationship to this * This has the The advantage that indicators can be used that respond even at lower temperatures. This advantage becomes clear in particular according to the further development according to claim 6 and can be influenced by the selection of the material for the handle and / or finger protection in the case of a two-part design of the handle on the cover. A two-part design of the handle to the lid or in other words, a separate finger guard has furthermore the advantage that the finger guard can be used directly as a carrier for the indi- · er, so that a simpler finishing and conversion \ of the container with an indicator according to the invention is possible.

The further development according to claim 7, preferably in conjunction with that according to claim 8, ensures that after reaching a certain temperature of interest in the container, for example that of the food boiling or cooking in the container, the indicator undergoes a clearly illuminated color change. This color change then serves as an indication or instruction to switch off or switch or downshift the heat source. This flashing notice remains even after the temperature rises further above the specific temperature specified on the indicator - at least for a certain time ^! certain period of time - exist and only go out when the temperature drops below the specified temperature. The indicator display is preferably reversible, so resets itself automatically, so that the use of disposable indicators that are possible in and of themselves, but relatively expensive , can be dispensed with. ;

According to the further development according to claim 9, preferably in conjunction with that according to claim 10, liquid crystals ¹

used. These are chemical substances / used in normal Temperature are fluid, but at the same time in some ways how crystalline bodies behave and e.g. react to temperature with a change in color. Such a liquid crystal] is 2.B. one of Kolesterolesters preferably in microfoil-encapsulated Shape. These liquid crystals can, for example, simply be placed on a suitable base or carrier can be printed. The front side is expediently covered with a protective layer and the rear side with a fastening medium, for example a self-adhesive adhesive, in the present case it is advantageous to use the indicator in moisture-resistant plastic material, for example rigid PVC, to be sealed.

The development according to claim 11 provides a space-saving indicator, for example as a three-layer structure comparatively broad temperature display range.

The invention is explained in more detail using an exemplary embodiment on the basis of the accompanying drawings.

It show schematically

Figure 1 shows a container according to the invention with a

and indicators arranged in the area of the finger protection of the handle of the lid

FIG. 2 shows, on an enlarged scale, the indicator arranged on a semicircular indicator carrier according to Figure 1.

Figure 1 shows a container 1 for the preparation of food with the supply of heat with a removable cover 10. This is a type of cookware with handles 11 in the area of the cup-shaped part of the container and in the area

of the lid 10. The handle 11 on the lid 10 is provided with a finger guard 12. The finger guard 12 is in the present! the embodiment is formed in one piece with the handle 11. A two-part design of the handle 11 and finger guard 12, however, has the advantage that the finger guard 12 can serve directly as a carrier for receiving the indicator 2 ^! and thus an attachment and replacement of the indicator on the container 1 is possible in a simple manner.

As can be seen in FIG. 1, the indicator 2 is on a preferred one Place arranged in the area of the handle 11 of the lid lü, in the manner of a sticker or label (see Figure 2) on the finger guard 12. The indicator 2 is therefore arranged here in the area of the cover IO at a measuring point, which is a useful measuring point due to the condensate that forms on the underside of the lid when the container is closed for the determination of the temperature inside the container in an indirect way. For preparing food in the open pot, so-called cooking in an open pot, the indicator 2 or another indicator 2 'in the area of one of the Handles 11 in the pot area added sciin.

When a certain predetermined temperature is reached on the Measuring point, here on finger guard 12, is addressed by the indicator by changing color. This color change means that a temperature is reached at the measuring point, which is in relation to a temperature inside the container, and which for the Preparation of the contained preservative is essential. To clarify the display of the indicator 2, a Instruction, for example toggling, on the display panel or part of the display panel of the indicator 2 (in FIG. 2 in right section) light up. This "toggle" lights up then preferably until the temperature falls below the response temperature specified by the indicator. Of the The left section of the display field of the indicator shown in FIG. 2 can be specified for the display from below this Switchover temperature temperature range. - 7 -

'respectively. Temperature points can be used. In the example according to the figure, the switching temperature, which is approximately 32 ° Celsius, is preceded by the temperature points 20, 25 and 30 ° Celsius. The um-. switching temperature of 32 ° C according to 305 ° Kelvin corresponds • speaking in the present embodiment, with the arrangement of the \ indicator 2 in the lid handle 11 from plastic material Ěîńęâŕ temperature inside the container in which the listed therein \ cooks foods made.

: The indicator according to FIG. 2 therefore gives at least a section Visible and readable information about the temperature development in the container according to Figure 1. This gives the possibility

plates, for example when using an electric stove as a heat source, to reduce or terminate the supply of heat to the item to be treated in the container 1 in a timely manner, so that in a simple manner after Um- or Turning off the storage heat of the plates is better to use.
