To the application for a utility model

Capacity for liquid food products

The utility model relates to the glass industry, in particular to the means of storage and consumption of food products, mainly in liquid form, and can be used in public catering, as well as in everyday life.

Known wooden containers for liquids (Kovalev NI Tales of Russian cuisine. M., Moscow Worker, 1989, pp. 241-243), used for storage and consumption of liquid food products. Depending on the purpose, wooden utensils have a different external shape. Regardless of the place of manufacture of the wooden blanks of a given shape, they are primed with a clay solution, raw linseed oil and tin powder, the soil layer is dried, varnished based on linseed oil and quenched in ovens.

The disadvantage is the low consumer properties.

Also known is a ceramic container for liquid food products, used for storage and consumption of liquid food products, as well as cosmetics (Kovalev NI Tales of Russian cuisine. M., Moscow Worker, 1989, pp. 243-244). This dish has an arbitrary shape and is a blank made of ceramic material and annealed in a furnace at high temperature. Regardless of the source of raw materials and further use, ceramic dishes are covered with a layer of glaze, creating a decorative effect. But glaze can be coated with a layer made of paints based on metals and their oxides (the so-called B 65 D 23/02

lichrome painting), which creates an additional decorative effect after firing. The disadvantage is the low mechanical strength.

Known capacity for liquid food products in the form of a bottle (GB, patent 1487969, B 65 D 23/02, 1977), having a coating on the surface.

A disadvantage of the known containers are low light-shielding properties and mechanical strength.

The technical problem to which the present utility model is directed is to develop a container for liquid food products with enhanced mechanical strength, light-shielding properties and a decorative effect.

The specified technical problem is solved due to the fact that the container for liquid food products in the form of a glass bottle has a decorative coating on the outer surface, made by applying at least one layer of a clay solution or a solution of gypsum or paint with a texture for clay.

The specified technical problem is also achieved due to the fact that a second layer can be additionally applied to the surface of the container.

Fig. 1 shows a glass container on the outside 1, which is coated with a decorative coating 2, the basis of which is a clay clay solution or gypsum solution or paint with a clay texture.

A container coated with clay or gypsum or coated with a paint with a texture for clay has the following advantages:

- provides sufficient mechanical strength of the tank;

- the contents are protected from exposure to ultraviolet rays, which helps to preserve the taste and bouquet in drinks,

decorative effect increases; aesthetic and presentation look improves.

1. An example of implementation.

in a creative way, then the bottles turn over and move to the area where the excess solution is removed, and then follow to the drying zone. Excess solution is removed with a wiping element. Particularly effective was a two-layer coating.

Glass has macro- and micro-submicroscopic defects that determine the mechanism and feature of its destruction (strength). The appearance of surface defects on glass is due to the influence of structural and chemical inhomogeneities, foreign inclusions and submicroscopic crystallite formations, as well as the negative influence of the temperature gradient. The greatest influence on the state of the surface of glassware is exerted by its contact with the environment; As a result of such contact with solids, abrasive particles and surface-active substances, glass accumulates on the surface foci of brittle fractures of a crack of various degrees of opacity. The brittle destruction of glass under the action of external forces begins from its surface as a result of the formation and growth of microcracks.

As a result of the contact of the coating with the glass surface, a protective coating is created that excludes the appearance of new defects and reduces the softening effect of microcracks existing on the glass surface.

- Firstly, the water-repellent ability of the glass surface is increased. Such hydrophobization of glass reduces the softening effect of surface-active media and, above all, air moisture;

secondly, the surface of the glass bottles is protected from inducing foci of brittle fracture of microcracks, i.e. glass surface is preserved;

thirdly, the stress concentration decreases during destructive mechanical loads, i.e. acts as a protector. The coating strengthens the glass in 1.5 - 1, 8 times.

The strength of glass containers is the most important indicator determining its quality and reliability during operation. The application of various protective and hardening coatings on glass containers is the most common way to increase their operational reliability.

Claims (2)

1. A container for liquid food products in the form of a glass bottle having a coating on the outer surface, characterized in that the coating is decorative by applying at least one layer of a clay solution, or a gypsum solution, or a paint with a texture for clay. 2. The container according to claim 1, characterized in that a second coating layer is additionally applied to its surface.
