Description

The invention relates to technology (methods) for the manufacture of decorative and artistic drinking utensils, mainly gift glasses, wine glasses, glasses and glasses, with decorative and functional porcelain inserts, and to products made by such methods.

From the prior art, there are many ways to decorate glasses, wine glasses, glasses, glasses, and other varieties of drinking glass vessels (dishes) both for domestic consumption and as highly artistic works of gift and collection purposes. Vessels are equipped with various decorative elements not only outside, but also inside, not only with painting (including three-dimensional - see [1. Electronic resource (URL): https://posuda-bohemia.ru/bokaly_dlya_vina_250_ml_6_sht_elizabet_21] and thin overlays, but and placement of fresh flowers [2. Electronic resource (URL): https://floretika.ru/cvety-v-stekle-sedmoe-nebo] and artistically designed original three-dimensional elements inside the cavity of a transparent glass bowl of the container, with the possibility of their full or partial dipping into a drink that fills the bowl.

Materials such as glass, crystal, porcelain, precious metals and alloys, cement compositions, adhesives, gypsum, silicone, paints, etc. are widely used in the creation and decoration of dishes, the creation of art products based on vessels.

At the same time, methods for painting artistic ceramic products are known - decorating a ceramic base with colored ornaments and / or pictorial and artistic painting, one of the two known main methods of painting - overglaze and underglaze, all of which are carried out on a prepared surface and include firing operations with with its own characteristics. [3. RU 2155172 C2, IPC C04B 33/34, C04B 41/86, 27.08.2000, author. - patent holders - Astasheva S.M. and Rossikova N.B.].

Underglaze paints, and this is a mixture of metal oxides, are fired at a temperature not exceeding 1350 ° C; overglaze paints are a mixture or alloy of light-alloy glasses and fluxes with the addition of pigments (ceramic paints), which are fired at a temperature of 760-840 ° C).

Known methods for the manufacture of artistic ceramic products, including the preparation of ceramic mass, molding, decorating the surface with mineral fibers, drying, firing [4. RU 2006141750 А, IPC С04В 33/34, 05/27/2008, author. - patent owner - Shchepochkina Yu.A.].

There are also known "exotic" methods of decorating ceramic products, for example, by filling the cells of a ceramic blank with a thermoplastic decorating material with a coefficient of thermal expansion (CTE) that differs from the CTE of ceramics by no more than 10%, followed by heat treatment [5. RU 2142925 C1, IPC С04В 33/34, С04В 41/86, 12/20/1999, patentee - CJSC "Enterprise of Traditional Folk Crafts "Izrazets"].

However, when craftsmen use ready-made (“purchased”) vessels as basic items (details of a future item, work) for decoration, the problem arises that the reliefs of the bottom of the bowl of each base vessel are not identical even within a series (batch) of machine production, not to mention handicraft - handicraft supplies. This is due to the peculiarities of the manufacture of glass products in general and, in this case, often leads to a significant error in mating the base of the three-dimensional insert element, which is not adapted to the bottom relief of the bowl of the base vessel, with this very bottom. In full growth there is a need for such adaptation (fitting). Accordingly, technologies in various other areas of human activity are recalled, using the removal of casts from surfaces of irregular stereometric shape (foundry, prosthetics, removal of death masks, in the end ...

So, an example of the use of silicone models and gypsum matrices (moulds) can be a method of manufacturing a glass product and a product made in this way [6. RU 2719674 C1, IPC S03V 19/00, 04/21/2020, patent holder - Leto LLC, RU]. However, it does not cover how to install porcelain elements in the cavity of the bowls of glass vessels.

In the "parallel" field of science and technology - dentistry (prosthodontics), an example of a permanent connection of physical bodies from such dissimilar materials as metal ceramics and an implant, an implant with an implant or with bone tissue, an example of a dental cement system is appropriate [7. RU 2448679 C2, IPC A61K 6/06, 09/27/2011 (WO 2009/025599 dated 02/26/2009), patent holder - Doxa AB (SE)]. However, no examples of borrowing such technologies in individual operations of dish decoration methods have been found.

Known vessel (glass with a bell), the upper, preferably silver (also allowed crystal) bowl is inserted into a preferably silver bowl-shaped intermediate stand-leg and permanently fixed in it with special latches or a layer of glue (which is not specified) over the entire ball segment of the contact patch , and the structure thus formed is rigidly connected to a preferably silver bell (with a movably suspended three-dimensional element built into the bell cavity - a silver tongue, while the second function of the bell is to support the glass [8. RU 167250 U1, IPC A47G 19/22, 12/27/2016 , patentee Petrov A.Yu. (RU)].

A method is known for manufacturing and permanent installation of a decorative or artistic three-dimensional element made of glass into the cavity of the bowl of a glass drinking vessel (glass), in which a decorative three-dimensional element (in in this example - a shark figurine in its horizontal position) [9. Shark wine glass - URL: https://podarki.ru/kupit/Bokal-dlya-vina-Akula-5971553]. The connection of glass parts to each other is carried out either by local heating or by gluing with a homogeneous substance - liquid glass, as a rule, of the same chemical composition as the parts themselves.

However, this method, for all the usefulness of the technical result of the technology and the product, is unsuitable for installing a porcelain element in a glass bowl of a vessel, since the problem of combining glass with porcelain at the current level of development of technology and technology (according to publicly available sources of information) has not been removed.

A method is known for manufacturing a decorative or artistic cooling three-dimensional element in the cavity of the bowl of a glass vessel for drinking, in which the ice element is made by freezing in the form or by mechanical processing of a piece of ice, introduced into the cavity of the bowl and fixed on its bottom by thermal means (cooling the bottom of the bowl to negative temperatures on the Celsius scale), and products made by this method [10. Electronic resource (URL): https://archidea.com.ua/rarity/unusual/358637-3d-figurki-v-bokalah].

However, this method of manufacturing the insert element is excessively expensive due to the one-time use, and the method of its installation by “cold soldering” cannot be used for any other materials of the insert element, except for ice.

The closest technical (technological) solution to the claimed is a method of manufacturing and installing a decorative aerating volumetric element in the cavity of the bowl of a glass drinking vessel, in which a decorative aerating volumetric element is made and permanently fixed with a base in a support round socket in the center of the bottom of the cavity of the bowl of a glass drinking vessel. [eleven. RU 2500327 C2, IPC A47G 19/22, B65D 25/08, 12/10/2013 (WO 2010/059269 dated 05/27/2010, patentee - CHEVALIER COLLECTION, US), "A glass for a drink with an internal decanting, filtering, mixing and aerating element ", Fig. 10-14, 3].

In it, the volumetric element, the bowl and the leg of the vessel are made of glass, which does not cause serious technological problems with their connection, including local thermal fusion or gluing with liquid glass. At the same time, sanitary requirements for the product as drinking utensils are met. An element made of another material (ceramic or metal) is inserted removable into the cylindrical socket of the central glass column (mechanical friction connection) formed at the bottom of the vessel bowl. The element in the form of an artificial flower is dual-functional: it is an aerator for a drink poured into a bowl and a decorating element of a vessel. Products made by this method are also known from the same source.

However, this method, for all the usefulness of the technical result of the technology and the product, is unsuitable for installing a porcelain element in a glass bowl of a vessel, since the problem of combining glass with porcelain at the current level of development of technology and technology (according to publicly available sources of information) has not been removed. This is most clearly manifested in economically justified attempts to use mass-produced glass vessels, which were not originally designed for such modernization. With known thermal methods, the required temperature when fixing the insert element can reach 500 ° C, which will ruin the original products under conditions of a difference in the thermal conductivity coefficients of glass and porcelain by about 2.5 times. The second technological problem is the difficulty of forming a seat in the body of such a hard, fragile and, as a rule, not designed for such an upgrade, a material such as glass or crystal, especially in the form of a thin, elegant vessel. The third, also important, problem should be called the fact already noted in the fifth paragraph of the description of the claimed invention, the fact of significant deviations in the shape of the bottom of the bowl of each base vessel from the average value of a particular batch of these products (which negatively affects the quality of the connection of mating parts during decoration).

The problem to be solved by the present invention is the lack of technical solutions for a reliable one-piece connection of the porcelain insert element with the base glass vessel, especially including the prefabrication of such an element of complex shape, with decorative or artistic plus aerating properties.

The technical result of the invention is the creation (development) of a method (technology) for the manufacture and installation of a decorative or artistic aerating three-dimensional element in the cavity of the bowl of a glass drinking vessel, devoid of the noted disadvantages of the prototype and allowing the implementation of a reliable and hygienically suitable one-piece connection of components from such dissimilar materials as glass and porcelain, plus scatter of the relief of the bottom of the bowl of each base vessel, due to separately available means at the achieved level of development of science and technology, which improves the consumer qualities of products (household items and fine arts) obtained in this way (including decorative and / or artistic effect), expands the possibilities of expanding the range of products.

To achieve the specified technical result, a method for manufacturing and installing a decorative or artistic aerating volumetric element in the cavity of the bowl of a glass drinking vessel, in which a decorative or artistic aerating volumetric element is made and permanently fixed in a round support socket in the center of the bottom of the cavity of the glass drinking vessel bowl, according to the invention, contains a sequence of operations:

a silicone cast is taken from the inner surface of the vessel bowl forming its cavity;

a silicone cast is skimmed;

the dimensions taken by skimming the cast are adjusted upwards to compensate for the 12% shrinkage of the porcelain mass;

according to the results of the mentioned skimming and size adjustment, a drawing or a 3D computer model of the inner surface of the vessel bowl is made;

in the center of the bottom of the bowl of the glass vessel, a hole with a conical countersink is drilled with a tubular tool, thereby starting the formation of the said round support socket;

breaking off and removing the center glass pin formed by drilling, thereby substantially completing the formation of the support seat;

the bowl of the vessel is washed, dried and degreased, at least the bottom of the cavity of the bowl, including the formed support seat;

a reference nest is skimmed and, by adjusting the shape and dimensions, its drawing or a 3D computer model is created;

a supporting base of a decorative or artistic aerating volumetric element is designed so that it forms a combination of a nest insert and a stand;

on the basis of drawings or computer models of the inner surface of the vessel bowl and said support base, a single drawing or computer 3D model of the inner surface of the future matrix with the shape of the vessel bowl with a support socket and a cavity for forming the stand is created;

according to the specified model, a solid-state matrix of the vessel bowl is made stereometrically corresponding to it;

the first, smaller part of the raw porcelain mass is placed on the bottom of the cavity of the matrix and it is knocked out, densely filling the matrix socket with it, with some excess of the volume of the mass, thereby forming a blank for the support base of a decorative or artistic aerating volumetric element, so that the support base forms a set of socket insert and coasters;

on said base blank, a second, most of the raw porcelain mass is fixed and a blank of a decorative or artistic aerating volumetric element or, at least, its lower fragment-base under its separately manufactured/purchased upper fragment is formed;

the workpiece of the mentioned element is dried with a hair dryer without removing it from the matrix;

after drying with partial shrinkage of the porcelain mass, said element blank as a whole, that is, the combined first and second parts, is removed from the matrix;

carry out scrap annealing of said workpiece in a furnace, followed by painting and further poured firing;

a fastening fluid composite composition is introduced into the support socket of the previously processed vessel by about half of its volume;

the finished decorative or artistic aerating element is inserted with a socket insert into the socket of the vessel bowl with a force sufficient to fill the entire annular gap formed in the support socket, including the countersink;

correcting if necessary, fixing the element in the cavity of the vessel bowl in a predetermined position relative to the vessel bowl;

the vessel, with the element fixed in the vertical position of the first one, is irradiated with an ultraviolet light source, thereby activating the polymerization process of the mentioned bonding composition;

upon completion of the polymerization of the bonding composition, determined by the set time delay, the method of installing a decorative or artistic aerating element in the cavity of the vessel bowl, as a production and technological process for creating the product, is considered completed.

A number of additional features and sets of features of the proposed method are also aimed at eliminating the above problem (while maintaining the main set of essential features - the sequence of operations with material means on a material object), namely:

- between the mentioned operations of drilling the support nest in the vessel and breaking off the glass pin, the nest can be treated with an abrasive tool, for example, an abrasive body of revolution in the shape of the support nest or a sandblasting device, thereby increasing the roughness of its surface (this further improves the quality of preparing the surface of the nest for connecting a three-dimensional element with a bowl, since it is supposed to carry out such a connection by means of a bonding cement bond due to a flowable composite composition, and the adhesion of the latter to glass is much higher with a higher surface roughness);

- a decorative or artistic aerating three-dimensional element can be made of porcelain, mainly with color painting (this is most valuable in relation to solving the problem of combining products from dissimilar materials with different CTE and gives a positive effect, maximally enhanced by artistic, aesthetic and taste needs);

- at the same time, a three-dimensional element can be made in the form of an artificial flower, from a highly plastic porcelain mass, mainly of the "Parian" type, manually;

- as an alternative to the previous one, a three-dimensional element, at least without a base, can be made in the form of a figure, from bone china by casting into a mold (this allows using the rich technological experience of cast porcelain products);

- in the case of underglaze painting, the scrap firing of the said blank is carried out in a furnace at a temperature of 950-1050 ° C, followed by painting and further poured firing at a temperature not exceeding 1250 ° C, thereby forming a solid porcelain structure and glaze on the surface (this, according to author's production experience and, taking into account previously known recommendations, optimizes heat treatment modes at the appropriate stages of the proposed method);

- in the case of overglaze painting, the scrap firing of the said workpiece is carried out in a kiln at a temperature not exceeding 1250°C according to a given program, followed by painting and further firing at a temperature of 760-820°C (this is also, according to the author's production experience and taking into account earlier known recommendations, optimizes heat treatment modes at the appropriate stages of the proposed method);

- a dental composition of the type of hydrating cement systems can be used as a fastening fluid composite composition (this, as established by the author-applicant in logical and empirical ways, is the optimal composition for today in terms of adhesive and strength properties, plus it clearly corresponds to stringent hygienic requirements for the entire product as a vessel for drinking, and with certification);

- a model of the inner surface of the future matrix and the matrix itself can be formed from gypsum (this is most consistent with the technological tradition of molding in a single production, by craftsmen-masters, often in domestic conditions);

By the claimed method, products manufactured according to it are also presented for legal protection.

In the claimed method of manufacturing and installing a decorative or artistic aerating volumetric element in the cavity of the bowl of a glass drinking vessel, a decorative or artistic aerating volumetric element 4 is made and permanently fixed by the base in the support round socket 1 in the center of the bottom of the cavity of the bowl 2 of the glass vessel 3 for drinking (see Fig. Fig. 1-4).

The method contains the following sequence of operations:

remove silicone (for example, brand Sealant "Viksint U-1-18") cast 12 from the inner surface of the bowl 2 of the vessel 3, forming its cavity;

a silicone cast 12 is taken, at least from the bottom 5 of the cavity of the bowl 2 with a socket 1 (the cast 12 is distributed, except for the bottom 5 of the bowl 2 of the vessel 3, and on the walls of the cavity of the bowl 2, in order to observe further on the matrix 14 (see Fig. 9, 10, 13) the size of the cavity of the bowl 2 in diameter in order to limit the dimensions of the volumetric element 4 formed in the matrix 14 - see Fig. 7);

a silicone cast 12 is skimmed;

adjust the dimensions taken by skimming the cast 12 upwards to compensate for the 12% shrinkage of the porcelain mass;

according to the results of the above skimming and size adjustment, a drawing or a 3D computer model of the inner surface of the bowl 2 of the vessel 3 is made (see Fig. 13-16);

in the center of the bottom 5 of the bowl 2 of the glass vessel 3 is drilled with a tubular tool (drill, for example, diamond) 6 a cylindrical hole 7 with a conical countersink 8 (mainly with an angle of 45 °) due to a conical (for example, diamond) nozzle 9, mainly with an angle of 45 ° at the top of the cone, thereby starting the formation of the mentioned round support socket 1 (see Fig. 5);

breaking off and removing (for example, with tweezers 10) the central glass pin 11 formed as a result of drilling, thereby basically completing the formation of the said round support socket 1 (see Fig. 6);

the bowl 2 of the vessel 3 is washed, dried and degreased, at least the bottom 5 of the cavity of the bowl 2, including the formed nest 1 (not shown in the illustration);

the support seat 1 is skimmed and, by adjusting the shape and dimensions, its drawing or 3D computer model is created (see Fig. 13-16);

a support base 15-16 of a decorative or artistic aerating volumetric element 4 is designed, so that it forms a combination of a socket insert 15 and a stand ("pips") 16 (see Fig. 9, 13-16, 1);

on the basis of drawings or computer models of the inner surface of the bowl 2 of the vessel 3 and the aforementioned support base 15-16 (see Fig. 13-16), create a single, respectively, drawing or computer 3D model of the inner surface of the future matrix 14 with the shape of the bowl 2 of the vessel 3 with a support socket 1 and a cavity for forming a stand 15-16 (see Fig. 8a, b);

according to model 13 (see Fig. 8a, b) or 13-16, a solid-state matrix 14 of the vessel bowl is made stereometrically corresponding to it (see further in the text and Fig. 9, 10);

the first, smaller part of the raw porcelain mass is placed on the bottom of the cavity of the matrix 14 and it is knocked out, densely filling the matrix nest with it with some excess of the mass volume, thereby forming a blank for the support base of a decorative or artistic aerating volumetric element, so that the support base forms a set of socket insert and stands (see Fig. 9, 11);

on the aforementioned workpiece of the supporting base 20-21 (a set of stand-"pipka" 21 with a socket insert 20) the second, most of the raw porcelain mass is fixed and a workpiece of a decorative or artistic aerating volumetric element or, at least, its lower fragment-base is formed separately manufactured / purchased upper fragment (see Fig. 11, 12);

the workpiece of the mentioned element is dried with a hair dryer without removing it from the matrix (see Fig. 11, 12);

after drying with partial shrinkage (12%) of the porcelain mass, said blank element 4 as a whole, that is, the combined first and second parts, is removed from the matrix 14;

carry out scrap annealing of workpiece 4 in a furnace, followed by painting and further poured firing (not shown in the illustration);

in the support socket 1 of the previously processed vessel 3, approximately half of its volume is injected with a fastening fluid composite composition 19;

the finished decorative or artistic aerating element 4 is inserted with a socket insert 20 into the support socket 1 of the bowl 2 of the vessel 3 with a force sufficient to fill the entire annular gap formed in the support socket, including the countersink (see Fig. 1, 3);

correcting if necessary, fix the element 4 in the cavity of the bowl 2 of the vessel 3 in a predetermined position relative to the bowl 2;

vessel 3, with element 4 fixed in it in the vertical position of the first one, is irradiated with an ultraviolet (UV-) light source, thereby activating the polymerization process of the mentioned bonding composition 19 (not shown in the illustration);

upon completion of the polymerization of the bonding composition 19, determined by the set time delay, the method of installing a decorative or artistic aerating element 4 into the cavity of the bowl 2 of the vessel 3, as a production and technological process for creating the product, is considered completed (see Fig. 1-4).

In the recommended rational special cases (examples), the proposed method is characterized by the following additional features and sets of features (operations).

Between the mentioned operations of drilling (tool 6, 9) of the support socket 1 in the vessel 3 and breaking off the glass pin 11, the socket 1 can be processed with an abrasive tool, for example, an abrasive body of revolution in the shape of the support socket 1 or a sandblasting device, thereby increasing the roughness of its surface (by Fig. not shown, the equipment is known and quite available).

Decorative or artistic aerating volumetric element 4 can be made of porcelain, mainly with colored painting.

In this case, the volume element 4 can be made in the form of an artificial flower, from a highly plastic porcelain mass, mainly of the "Parian" type, manually (see Fig. 1-3).

As an alternative to the previous one, the three-dimensional element 4, at least without the base 20-21, can be made in the form of a figurine (see Fig. 4), from bone china by mold casting.

In the case of underglaze painting, the said blank is fired in a kiln at a temperature of 950-1050°C, followed by painting and further poured firing at a temperature not exceeding 1250°C, thereby forming a solid porcelain structure and glaze on the surface.

In the case of overglaze painting, the above-mentioned workpiece is fired in a kiln at a temperature not exceeding 1250°C according to a given program, followed by painting and further firing at a temperature of 760-820°C, thereby forming a solid porcelain structure (when using porcelain mass of the brand "Parian" during the firing process, a natural glaze is formed, due to the presence of a large amount of glass fluxes in this mass, which allows immediately after the first firing at 1250 ° C to paint the workpiece, usually a flower, with ceramic overglaze paints without applying glaze).

As a bonding fluid composite composition 19, a dental composition such as hydrating cement systems can be used (see, for example, [7]).

The model of the inner surface of the future matrix 14 and the matrix 14 itself can be formed from gypsum (see Fig. 11).

During the operation of products repeatedly mentioned above in the text aeration of the drink (mainly when pouring into the bowl 2 of the vessel 3) occurs similarly to the prototype and therefore does not need to be explained. Decorative and artistic effects - even more so.

The claimed method is also subject to legal protection of products manufactured according to it (see Fig. 1-4).

The specific types of materials indicated in the description are special cases (examples) of the claimed invention and are not intended to limit its application. It is possible to use other materials that provide the same or similar functional characteristics (technical result).

In terms of the technical result, it should be noted that there is no need for joint high-temperature heat treatment of the vessel and the insert element made of materials with significantly different coefficients of thermal expansion (TEC), while ensuring, nevertheless, very satisfactory (as shown by the author's practical experience) strength characteristics (stand " pipe" in a cylindrical-conical socket 1 reliably compensates for bending stresses under real dynamic loads on the plug-in element 4, including inertial ones), and the used bonding composition 19 ("dental cement") not only provides a very reliable connection of glass with porcelain on a small contact surface , but also a priori convincingly meets the sanitary and hygienic requirements for food utensils.

So, the technical result of the proposed invention is the creation (development) of a method (technology) for the manufacture and installation of a decorative or artistic aerating volumetric element in the cavity of the bowl of a glass drinking vessel, devoid of the noted disadvantages of the prototype and allowing the implementation of a reliable and hygienically suitable one-piece connection of components from such dissimilar ( in terms of thermophysical characteristics) of materials such as glass and porcelain, due to separately available means at the achieved level of development of science and technology, which improves the consumer qualities of products (including decorative and artistic effects when using household items and fine arts) obtained in this way. way, expanding the range of products.

Although the present invention as a whole has been described in detail in connection with specific preferred particular cases (examples) of execution, it is obvious that many alternatives, modifications and special cases will become apparent to a person skilled in the art in view of the foregoing description. Thus, the appended claims are not intended to be limited to the particular preferred embodiments disclosed herein, and are intended to cover any such alternatives, modifications, and examples falling within the true scope and spirit of the present invention.

The claimed method, as well as products made in this way, are not speculative and are not a purely theoretical development, but "suffered" by the author in experimental and practical development, with the optimization of technological methods.
