Description

The utility model relates to service equipment of refrigeration equipment and can be used in food, pharmaceutical, medical and other industries where it is necessary to control the storage temperature of the product and the possibility of establishing the fact of its unauthorized defrosting.

Frozen semi-finished products after thawing and re-freezing lose their consumer qualities (such as appearance, taste, aroma, etc.). Many of these products - meat, fish - become hopelessly spoiled and even harmful to health, as they become a breeding ground for numerous bacteria that are not destroyed by repeated freezing.

The end consumer does not have the ability to reliably determine whether the specific packaging of the product that he intends to purchase has been thawed and re-frozen, since the existing indicators for defrosting freezers have the following disadvantages:

- they determine, as a rule, the unauthorized defrosting of the camera itself, and not the specific packaging of the product that could be stored at positive temperatures and frozen immediately before sale;

- the end user does not always have or, moreover, practically does not have access to the indicator;

- Existing indicators can be used repeatedly, which allows dishonest employees to hide the fact of unauthorized defrosting from the end user.

Defrost indicators are known [SU copyright certificate No. 1295166, US patent No. 4114443, RU patent PM No. 27221], which are a housing consisting of two parts, one of which is at least made of transparent material and partially filled with liquid. The duration of defrosting is determined by the level of melted ice using a series of patterns printed on the indicator body. All three analogs allow multiple

the use of indicators after defrosting events, which is not so much a positive advantage as a negative one for the end user, as he may not be informed about the violation of the product storage mode.

Of the aforementioned analogues, US patent No. 4114443 describes an indication device consisting of a housing in which there is a transparent and opaque part. The latter is filled with colored liquid. In the opaque part there are stops for fixing the frozen liquid. Defrost duration is determined by the level of melted ice in the transparent part.

The disadvantage of this design is the lack of safety, as it is possible to destroy the device during defrosting of the working fluid. In addition, this indicator allows you to hide the fact of unauthorized defrosting during product storage, since this indicator is not presented to the final consumer.

Another analogue is the defrost indicator [RU patent for invention No. 198098], which is made in the form of a partially filled hollow body with horizontal marks and consists of two similar parts of transparent material made in the form of two truncated cones connected by smaller bases. The difference of the indicator is the implementation of large bases of truncated cones of metals or metal alloys.

The indicator is installed in the chamber so that frozen water is in its upper part. At temperatures above 0 ° C, the ice in the indicator melts and flows to the bottom of the indicator, gradually passing marks that allow us to estimate the time during which the temperature was above 0 ° C. With a prolonged increase in temperature, the ice completely turns into water. When the camera enters normal mode, the indicator flips and is ready for use again.

Closest to the claimed indicator is a device for visual control of the fact of freezing or thawing products in containers (mainly food, during storage and transportation) - RU patent No. 27221 for a device that includes a case on which a transparent window is made, a thermal display unit in the form of glass ampoules filled with coloring liquid. The unit of attachment of the device to the container is made in the form of a sticky non-renewable strip covered with a protective film. In case of defrosting of the product at any stage of storage or transportation, the ampoule of the device breaks and

the absorbent element is stained with liquid. And the product receiver will observe a color indicator in the case window, which unequivocally establishes the fact of violation of the temperature regime of storage and transportation of frozen products.

However, this design allows you to hide the fact of unauthorized defrosting from the final consumer of the product, since it was developed specifically for determining the defrosting of low-temperature chambers and household refrigerators by the product receiver.

The objective of the claimed utility model is to develop a miniature, easy to use, cheap and at the same time informative defrost indicator, including for the end user.

The inventive utility model is characterized by the fact that the defrost indicator of products to be stored at temperatures that exclude defrosting has a shell with at least one side of the visualization, the packaging of the controlled product and transparent packaging of the indicator with indication elements excluding its removal without breaking are placed in the shell the integrity of the packaging of the controlled product, while the display elements are made in the form of pre-formed ice figures of two different colors with the possibility of ensure that when mixing them as a result of the melting of a sharply distinguishable third color, which serves as a defrost marker.

An indicator of defrosting products is also declared, one of the signs of which is the performance of ice figures with a given configuration.

A modification of the defrosting indicator of products with the above characteristics is also claimed, in which the packaging of the controlled product is located in direct contact with the packaging of the indicator.

The technical result of the claimed utility model. The solution to the problem of determining the fact of unauthorized defrosting of products to be stored at temperatures that exclude defrosting, using indicators is expressed by their technical characteristics such as reliability in operation, information content, mobility in transportation and storage, simplicity. An important technical result of the proposed indicator is that a violation of the necessary storage conditions for products can be detected by both a specialist and each end user without violating the integrity of the package due to its transparency and the location of indicators near the product, as well as the design features of the indicator itself. Suggested indicator

defrosting products is intended to facilitate recognition of product quality, taking into account the fact of unauthorized defrosting, including by the end user. Using the proposed defrost indicator in the food industry will allow, firstly, to prevent food poisoning of end consumers due to temperature violations, secondly, to increase the overall service culture in various retail outlets, thirdly, to favorably affect the perception of end consumers of products, labeled with indicators, and their manufacturers. It is also possible to use the proposed indicators in the field of medicine (storage and transportation of donated blood, organs for transplantation, etc.).

1-8, the positions 1-7 are indicated:

1 - indicator packaging,

2 - packaging of a controlled product,

3 - controlled product,

4 - display elements,

5 - common shell

6 - liquid filler,

7 - fastening element.

The inventive defrost indicator includes a package of 1 indicator, a package of 2 controlled products, elements 4 of the indication, enclosed in a common shell 5 (for example, polyethylene shrink film), which provides contact of the indicator with the controlled product 3 and eliminates the separation of package 1 of the indicator from packaging 2 of the controlled product without violation of the integrity of the package 2 and the common shell 5 (Figure 1). The latter has at least one side of the visualization. Display elements 4 are made in the form of ice figures, pre-formed with a given configuration and two different colors, and placed in the packaging 1 of the indicator with the ability to contact with each other. When mixed as a result of melting, the ice figures provide a sharply distinguishable third color, which serves as a defrost marker in the form of a liquid filler 6.

As the colors of the display elements 4 are used, for example:

- cyan (on the CMYK scale - 100% Cyan (cyan), 0% Magenta (magenta), 0% Yellow (yellow), 0% Black (black), on the RGB scale - R (red) - 0, G (green) - 147, B (blue) - 221),

- yellow (on the CMYK scale - 0% Cyan (cyan), 0% Magenta (magenta), 100% Yellow (yellow), 0% Black (black), on the RGB scale - R (red) - 255, G (green) - 245, V (blue) - 0).

When mixing liquids resulting from the melting of display elements 4, a sharply distinguishable green color is obtained (on the CMYK scale - 100% Cyan (cyan), 0% Magenta (magenta), 100% Yellow (yellow), 0% Black (black), according to RGB scale - R (red) - 0, G (green) - 146, B (blue) - 63), which serves as a defrost marker. In fact, the basis of all color systems is a system whose addition curves are determined experimentally by the method described above. Its primary colors are pure spectral colors corresponding to monochromatic radiation with wavelengths of 700.0 (red), 546.1 (green) and 435.8 nm (blue). The initial (reference) color is the color of the even-energy white E (i.e., the color of the radiation with a uniform intensity distribution over the entire visible spectrum). The curves of the addition of this system, adopted by the International Commission on Lighting (CIE) in 1931 and known as the CIE RGB colorimetric system (from English, German, red, rot - red, green, grun - green, blue, blau - blue, blue ) (See Great Soviet Encyclopedia).

The indicator of defrosting products works as follows. To the controlled product 3, located in the package 2, attach the package 1 indicator with placed in it elements 4 of the display. The packaging 1 indicator with display elements and the controlled product 3 can be placed in a common shell 5 (Figure 1). While the storage temperature of the controlled product 3 is negative, the display elements 4 retain their shape (Figure 2). When the temperature rises above 0 ° C, display elements 4 begin to melt, losing their shape. The liquids obtained by melting the display elements 4 of different colors are mixed, acquiring the third color of the formed liquid filler 6 (Figure 3). If the temperature exceeds 0 ° C for a long time, the display elements 4 melt completely, in the packaging 1 of the indicator remains a liquid of a third color, different from the original ones, - Figure 4. Upon repeated freezing, the liquid freezes, however, the color of the marker remains (Figure 5). The fact of unauthorized defrosting is fixed.

Packaging 1 indicator and packaging 2 of the controlled product can be connected using fasteners in the form of an additional weld seam or self-destructive seal tape, or polymerizing glue.

Example 1 - Figure 6 shows how, in this case, the packaging 1 of the product defrost indicator is made at the same time as the packaging 2 of the controlled product with the exception of direct contact of the display elements 4 and the controlled product. If the package 2 of the controlled product is a plastic bag, the differentiation is provided by the fastening element 7, presented in the form of an additional weld when forming the package.

Example 2 - Figure 7 shows how the indicator package 1 is connected to the package 2 of the controlled product using the fastener 7, presented in the form of a self-destructive seal tape, which provides contact and irreparably collapses when you try to separate the indicator package 1 from the package 2 of the controlled product .

Example 3 - Fig. 8 shows how the indicator package 1 is attached to the package 2 of the controlled product using the fastener 7, which is in the form of a polymerizing adhesive, which provides contact and irreparably breaks when you try to separate the indicator package 1 from the package 2 of the controlled product.
