Container for food preparation with means of temperature indication

FIELD: food industry.

SUBSTANCE: invention relates to the container for food preparation with means of temperature indication. The container for food preparation contains structural components located outside of the main casing of the container. Detachable label with covering containing thermal chromatic pigments is applied to the components. Also the labels are detachable, have different configuration at that different temperature sensibility of the pigments corresponds to each of these configurations.

EFFECT: improvement of signalling means of reached temperature, decrease of costs for the method of applying these means.

Background of invention

The present invention relates to a vessel for cooking tool temperature display.

When using pots would be useful during and after cooking to show that the pan has reached the set temperature and its parts are hot enough, thereby allowing the user to take action against burns.

Already known and commercially available pots and pans, in a Central position of the bottom of which is covered with a coating containing termograficheskoe pigment that changes color shows that the bottom has reached the set temperature.

However, this known solution has the disadvantage that it only shows the temperature corresponding to the Central part of the bottom of the pan, as opposed to external sites.

Moreover, if the pan is food, this chromatic indicator is not visible, because prigotavlivaemy food covers thermochromatic floor.

In another prototype uses a thermosensitive liquid crystal device, liquid crystal which is embedded in the handle of the pan, which, for example, made of plastic and extends outside the vessel.

Such known heat-sensitive device provides an indication of temperature, which, even in this case, is measured of novotronic parts of the vessel. This known device, however, is very complicated and, moreover, prone to breakage during operation due to the high temperature of the working areas of the vessel or due to the moisture and heat inside of dishwashers.

Brief description of the invention

Accordingly, the present invention is to overcome the above disadvantages of prototyping and creating a vessel for cooking, containing improved means for signaling reached the temperature, while such vehicle is arranged to be mounted outside of the vessel and applying inexpensive ways on external sites.

This goal is achieved by using a vessel for cooking, characterized in that it contains components that are located outside of the vessel, these components are coated with the layer containing thermochromatic pigments.

Brief description of drawings

Other features of the present invention will become apparent from the following description and appended claims.

What follows is a more detailed description of the present invention with reference to illustrative variant, illustrated in the accompanying drawings, in which figure 1 depicts a schematic top view of a vessel for cooking with the handle and the outer coating according to the of the present invention;

figure 2 - schematic view of the sequence of indicator labels applied on the outer surface of the vessel.

Description of the preferred option of carrying out the invention

Figure 1 shows a top view of a vessel 1 for cooking, equipped with a handle 2.

Mainly, the interior of the vessel 1 applied nonstick coating.

To the body of the vessel 1 by using fire-resistant plate 3 is attached well-known fire-retardant device 4, and the plate 3 and the device 4 is made of metal.

In this regard, it should be noted that it is possible to use other clamping systems, such as threaded studs welded to the hull of the vessel, where the handle can be locked with a screw.

From the flame-retarding device 4 is tubular housing, which is inserted into the handle 2, is made of metal or wood or synthetic material.

It should be noted that the term "vessel" also applies to other containers or vessels for cooking, such as frying pans, saucepans and similar containers or vessels.

On the external structural parts of the vessel 1 is covered with a coating containing thermochromatic pigments having different sensitivity.

This coating contains pigments, which, depending on the attained temperature change color, for example, with the similar black (as in the vessel 1 at room temperature) to red or red-orange, as the vessel is heated to cooking temperature, which can vary from 150°240°C.

The coating containing termograficheskoe pigment, known and available, for example, by Keystone. Figure 1 shows the various options for detecting and indicating the temperature inside the vessel 1.

For example, the case of flame retardant tubular device 4 may be covered with a layer 5 containing termograficheskoe pigment, prior to Assembly with the plate 3.

You can also place thermochromatic floor in any other suitable places.

In addition, you can apply the coating 6, containing termograficheskoe pigment, the handle 2, and, finally, can be applied by gluing on fire-retardant casing 4 or the handle 2 label 7 made of the coating layer containing termograficheskoe pigment.

This label 7 has the advantage that after a certain period of use of the vessel 1 and ageing termograficheskoe pigment tag 7 can be removed and replaced with a new one.

Moreover, such labels have the advantage that they can be produced commercially with low cost and quick and easy to apply.

Moreover, the labels with thermochromatic pigment may have a different shape for better visibility. As shown in figure 2, the label 7 is circular in shape, whereas the label 8 can have a square shape, and the mark 9, e.g. the measures may have a triangular shape.

Different form labels 7, 8 and 9 allows the use of labels with different sensitivity. For example, one label may contain thermochromatic pigments that change color at a temperature of 80-100°C. Other label can have a coating that changes color when approximately 150°and another label can change color in the temperature range 180-240°and these are just some examples.

A great advantage of the present invention is the fact that the temperature display is located inside the vessel. The indicator coating can be applied to various external components of the vessel, such as acting fire resistant enclosure in the mounting plate fireproof Cabinet or directly on the handle inserted in the tubular flame retardant enclosure or device.

The coating containing thermochromatic pigments that are sensitive to different temperatures, can be also applied to adjacent areas.

Special advantages of the coating containing thermochromatic pigments, spray.

Mainly, the said coating containing thermochromatic pigments can be applied by screen printing.

Moreover, it is convenient to put a layer containing a temperature-sensitive or thermosignal pigment, using the buffer system and Nikon is C, it is possible and convenient to put a layer containing termograficheskoe pigment, method of decal.

1. Vessel for cooking containing the components (2, 3, 4)located outside the main body of the vessel (1), on which is applied a removable label having a coating containing thermochromatic pigments, characterized in that the labels are removable, have different configurations, with different sensitivity to temperature pigments corresponds to each of these configurations.

2. The vessel according to claim 1, characterized in that the coating containing termograficheskoe pigment, deposited by sputtering.

3. The vessel according to claim 1, characterized in that the coating containing termograficheskoe pigment, deposited by screen printing.
