The prior art discloses a glass - an external holder for two capsules with protection against removal of the annular portion from the flange (RU 221349 U1, patent holder Vitaly Pavlovich Pankratov (RU), publication date 01.11.2023). The glass - an external holder for two capsules with protection against removal of the annular portion from the flange, consisting of a side wall containing a flange; a bottom containing two brackets, each of which is configured to hold one piercer; an annular portion containing drinking holes and configured to be connected to the flange; a capsule seat configured to be connected to the annular portion and configured to accommodate two capsules; contains a removable annular portion and a grip configured to fix the annular portion on the flange.

A glass - an external capsule holder is known from the prior art (RU 221567 U1, patent holder Vitaly Pavlovich Pankratov (RU), publication date 11/13/2023). The glass - an external capsule holder, consisting of a side wall containing a flange; a bottom containing one bracket configured to hold one piercer; an annular part containing drinking holes and configured to connect to the flange; a capsule socket configured to connect to the annular part and configured to accommodate one capsule, characterized in that it contains a removable annular part; a grip configured to fix the annular part on the glass.

The prior art discloses an external holder for three capsules equipped with side wall thermal insulation (RU 222650 U1, patent holder Vitaly Pavlovich Pankratov (RU), publication date 16.01.2024). The external holder for three capsules equipped with side wall thermal insulation consists of a side wall containing a flange; a bottom connected to the side wall and containing three brackets, each of which is made inseparable from one piercer; an annular part containing drinking holes and configured to be connected to the flange; a capsule nest made inseparable from the annular part and configured to accommodate three capsules; three piercers, each of which is inseparably connected to the bracket and is designed with the possibility of piercing the lower part of the capsule placed in the capsule nest, characterized in that it contains a removable annular part containing an internal projection designed with the possibility of pressing against the inner side of the side wall, and a grip designed with the possibility of fixing the annular part on the flange; an outer flask connected to the flange; a locking ring mounted on the outer side surface of the annular part, designed with the possibility of fixing the grips on the flange.

The closest to the claimed utility model is a thermos cup - an external holder of two capsules, equipped with grips, clamps and an annular shelf (RU 224877 U1, patent holder Vitaly Pavlovich Pankratov (RU), publication date 08.04.2024). A thermos cup is an external holder of two capsules, equipped with grips, clamps and an annular shelf, a system for the safe preparation of two-component drinks, consisting of a side wall containing a flange and an annular shelf, inseparably connected to the inner part of the side wall and configured to hold a piercer; a piercer containing two piercing elements, configured to be installed on the annular shelf and piercing the lower parts of two capsules placed in a capsule nest; a bottom, inseparably connected to the side wall; an annular part containing holes for drinking and configured to connect to the flange; a capsule nest, made with the possibility of connection with the annular part and made with the possibility of placing two capsules; containing marking made with the possibility of reading by a scanner of a car coffee machine, characterized in that it contains a removable annular part containing grips made with the possibility of fixing the annular part on the flange; an outer flask connected to the flange; a capsule nest, containing four locks located on the outer side of the vertical part of the capsule nest, made with the possibility of fixing two capsules installed in the capsule nest.

The disadvantage of the analogues and the prototype is that the cups contain piercers placed on the bottom of the cup, made in the form of pins with piercing parts, while the piercers are long and can bend and deviate to the side when resting against the lower parts of the capsules. In the case where the piercers are made in the form of a ring with jumpers and piercing elements and are placed on a ring shelf located on the inner part of the side wall of the cup, the piercing elements can bend downwards when resting against the lower parts of the capsules. In both cases, the lower parts of the capsules will not be punctured, which may result in hot water, which is supplied under pressure from the car coffee machine, being sprayed out through the “upper puncturer - capsules” connection or in the rupture of the water lines inside the coffee machine, which will also result in hot water being sprayed out, which may get on the passenger, burn him, stain clothes and/or the interior of the car.

In addition, in the known devices, the connection of the cup and the lid occurs using a flange on the upper part of the cup and a semi-toroidal shape of the mating part of the flange on the lid body. The disadvantage of such a connection is the complexity of manufacturing the flange on the upper part of the cup and the semi-toroidal shape of the mating part of the flange on the lid body, since these elements are complex figures, their production requires the manufacture of complex press molds that include special form-forming elements such as folding punches, composite and sliding matrices and special removal plates. Obviously, the more complex the press mold, the higher the percentage of defects.

Thus, the known designs are unsafe to operate.

The technical result achieved by the utility model consists in increasing the safety of operation of the declared device.

In order to achieve the technical result, a glass is claimed - an external holder of one capsule, equipped with an annular stop, hemispherical projections, an external flask, consisting of a bottom and a side wall, on the outer side of which there is an external thread, a lid consisting of a capsule nest and an annular part, the outer diameter of the lower part of which is equal to the inner diameter of the upper part of the glass, made with the possibility of installing the lid in the glass by thrust, characterized in that the annular part contains an external thread on the outer side surface, made with the possibility of installing the glass with the installed lid in a car coffee machine, wherein the glass contains one capsule piercer, made inseparable from the inner part of the glass body, having attachment points to the inner sides of the bottom and the side wall, wherein on the side of the outer part of the outer flask there is an annular stop, made with the possibility of supporting the user's fingers, wherein the annular part contains hemispherical projections on the outer side, and the side wall contains mating parts of the hemispherical projections of the upper part, made with the possibility of fixing the hemispherical protrusions after installing the lid in the glass, while on the outer side of the side wall there is an outer flask containing an internal thread on the upper part, connected to the side wall using a threaded connection.

The claimed device is an element of a safe beverage preparation system.

The safe beverage preparation system is a system of interconnected elements. The elements of the safe beverage preparation system are the car coffee machine 9, not equipped with an internal capsule holder, and the declared device.

The claimed device is connected to the car coffee machine 9 by means of the external thread 8, which is an element of the claimed device and the upper piercer and the internal thread, which are elements of the car coffee machine, wherein the upper piercer is connected to the capsule 4, placed in the claimed device, and the internal thread of the car coffee machine is connected to the external thread of the claimed device. Water moves from the car coffee machine to the claimed device, inside the elements of the safe beverage preparation system. This eliminates an open stream and ensures protection against liquid getting on the passenger and the car interior during a ride in shaking conditions.

The claimed device can be made, for example, from plastic and/or paper and/or metal, and contains a glass 2 consisting of a side wall 5, inseparably connected to a bottom 6, forming the body of the glass.

The claimed device comprises a lid 1 consisting of an annular part containing a drinking opening and a capsule nest 3, which is designed to accommodate the capsules in such a way that the drink flowing from the capsule 4 gets inside the glass 2. The capsule nest is designed to allow access and tight pressing of the upper piercer, which is an element of the car coffee machine 9, to the capsule installed in the capsule nest. The lid may comprise a limiter, which may be an annular protrusion designed to limit the displacement of the lid inside the glass.

To connect the lid 1 and the cup 2, the lid is inserted into the cup by thrust, for this purpose the outer diameter of the lower part, which is equal to the inner diameter of the upper part of the cup. This solution eliminates the need to manufacture a flange on the cup and a semi-toroidal shape of the mating part of the flange on the lid body, which increases the safety of the claimed device, since these elements are complex figures, their production requires the manufacture of complex press molds that include special form-forming elements, such as folding punches, composite and sliding matrices and special removal plates. Obviously, the more complex the press mold, the higher the percentage of defects, which can lead to the destruction of the elements or a loose fit of the elements to each other, this can lead to the removal of the lid from the cup or their loose connection, which will lead to splashing of a hot drink from the claimed device on the user and the car interior. Thus, connecting the lid and the cup by installing and tightly fixing the lid in the cup by thrust increases the safety of the claimed device.

The annular part contains an external thread 8, on the outer side. The external thread is designed with the possibility of installing a cup 2 with an installed lid 1 on a car coffee machine 9 from below, by screwing the claimed device into the car coffee machine from below under the upper capsule piercer, which is an element of the car coffee machine, which eliminates the need to use a cup holder, which is an element of the car coffee machine. Using an external thread to connect the claimed device to the car coffee machine increases the safety of using the claimed device in comparison with alternative options, for example, in comparison with an external solid or intermittent protrusion on the annular part, or in comparison with a cup holder, which is an element of the car coffee machine. The outer solid or intermittent protrusion on the annular part has a smaller contact area of the outer protrusion surface with its counterpart, which is an element of the car coffee machine, than the contact area of the external thread with the counterpart, which means a higher probability of breaking off the outer solid or intermittent protrusion when pressing the upper capsule piercer on the lid. Breaking off the outer protrusion will lead to the claimed device falling out of the car coffee machine, and the hot drink may splash, burn the user and stain the car interior. The connection using the external thread reduces this probability, thus increasing the safety of using the claimed device. The cup holder, which is an element of the car coffee machine, fixes the cup with the lid installed. The pressure created by the upper capsule piercer on the lid is transmitted from the lid to the cup, from the cup to the cup holder, from the cup holder to the body of the car coffee machine. Each of these elements may fail due to the depletion of the resource, and/or a manufacturing defect, and/or improper installation. The more elements in the pressure transmission chain from the upper piercer to the car coffee machine body, the higher the probability of failure, which can lead to the declared device falling out of the car coffee machine, while the hot drink can splash, burn the user and stain the car interior. The external thread has a large contact area with the mating part, which is an element of the car coffee machine body, and in the pressure transmission chain from the upper piercer, the external thread immediately transmits the created pressure to the car coffee machine body, eliminating the transmission of pressure to the cup and eliminating the need to use a cup holder. Thus, the use of external thread increases the safety of using the declared device.

The claimed device contains one piercer 7, located inside the body of the glass 2. The piercer is made inseparable from the glass by means of casting or gluing. The piercer has vertical supports with attachment points to the inner side of the bottom 6 and has horizontal struts made inseparable from the inner side of the side wall 5. The implementation of the piercer with horizontal struts, as well as the inseparable connection of the piercer with the body of the cup, increases the safety of operation of the claimed device in comparison with the embodiment of the piercer in the form of a vertical pin placed on the bottom, since such a piercer has a greater length and can bend and deviate when resting against the lower part of the capsule 4. In the event that the piercer is made in the form of a ring with jumpers and a piercing element and is placed on an annular shelf located on the inner part of the side wall of the cup, the piercing element can bend downwards when resting against the lower part of the capsule. In both cases, the lower parts of the capsule will not be punctured, which may result in splashing of hot water, which is supplied under pressure from the car coffee machine 9, through the "upper puncturer - capsule" connection or to a rupture of the water mains inside the car coffee machine, which will also result in splashing of hot water, which may get on the passenger, burn him, stain clothes and/or the car interior. Thus, the design of the puncturer is inseparable from the inner part of the bottom and from the inner part of the side wall, which increases the safety of operation of the claimed device.

The claimed device comprises a ring stop on the side of the outer part of the outer flask, designed to support the user's fingers. The ring stop has the shape of a ring, is made, for example, of plastic or pressed paper and is connected to the outer flask using, for example, casting, gluing, or another method. The ring stop allows the user to hold the glass more conveniently, preventing the glass from slipping out of the user's hand during shaking in transport, since during shaking the glass can slide in the hand and, under its own weight, slip out and fall on the floor of the car, open and burn the user and stain the car interior. When sliding down, the claimed device rests with the ring stop against the user's fingers, as a result of which the probability of the claimed device falling out of the user's hand is reduced. Thus, the ring stop increases the safety of the claimed device.

The claimed device comprises hemispherical projections made of the same material as the lid 1, made inseparable from the outer side of the annular part by casting, or gluing, or by another method. The side wall 5 of the cup 2 comprises mating parts of the hemispherical projections, which can be, for example, openings, or hemispherical recesses, the diameter of which is equal to the diameter of the hemispherical projections. The hemispherical projections fall into the mating parts of the hemispherical projections when the lid is installed in the cup. The hemispherical projections are designed with the possibility of fixing the lid in the cup. The presence of the hemispherical projections prevents accidental removal of the lid from the cup, which can lead to the spilling of a hot drink from the claimed device onto the user, thus, the hemispherical projections increase the safety of the claimed device.

The beverage poured into the declared device has a high temperature, high heat transfer through the side wall leads to the fact that high temperature is formed on the outer surface of the side wall. This can lead to a burn of the passenger's fingers and the fall of the declared device when instinctively unclenching the fingers, this can lead to the occurrence of a danger of the declared device with a hot beverage falling, splashing the beverage on the passenger and/or elements of the car interior.

In order to reduce such a danger, the claimed device comprises an outer flask containing an internal thread on the upper part. At the same time, on the outer part of the side wall there is an external thread made with the possibility of connection with the internal thread located on the outer flask. The outer flask is connected to the side wall using a threaded connection. The outer flask is made, for example, of plastic. The outer flask repeats the shape of the outer part of the side wall and the bottom, while the outer flask installed on the side wall does not touch the side wall and the bottom, thus, an air gap is formed between the outer flask and the side wall. Since the thermal conductivity of the air located between the side wall and the outer flask is less than the thermal conductivity of the plastic, the temperature on the outer surface of the outer flask is lower than on the outer surface of the side wall, this reduces the likelihood of burning the user's fingers, thereby increasing the safety of using the claimed device.

The use of a threaded connection of the outer flask and the side wall increases the safety of operation of the claimed device, in comparison with solutions in which the outer flask is made inseparable from the side wall, since the claimed device is manufactured using injection molding, and for the production of the claimed device it will be necessary to manufacture a mold into which molten plastic material is poured under pressure. A monolithic connection of the outer flask and the side wall will require a complex mold, which may include special shaping elements, such as folding punches, composite and sliding matrices and special removal plates. Obviously, the more complex the mold, the higher the percentage of defects. In the “Great Encyclopedia of Oil and Gas”, with reference to the book by Ya. A. Samokhvalov “Handbook of a Design Technician”, in Chapter 8 “Parts made of plastics” it is written: “…Undercuts worsen the manufacturability of parts, reduce their accuracy and surface quality, complicate the design of the press mold and limit productivity during pressing. By changing the design of the products, it is possible to avoid undercuts. If it is impossible to avoid undercuts, then in some cases it is advisable to dismember such a part into two (or more) simple parts…” p. 330, paragraph 5. https:// www.ngpedia.ru/ pg1127673pmQmENz0001274576/. Therefore, the production of the outer flask separately from the side wall will reduce the number of defects and, consequently, will reduce the likelihood of using defective declared devices, which increases the safety of the declared device, since the declared device, manufactured with a defect, can create a danger, for example, destruction of the side wall and outer flask during the operation of the declared device, as a result of which a hot drink may spill onto a passenger and/or elements of the car interior.

The utility model works as follows:

The user manually inserts the lid 1 into the glass 2. The user inserts one capsule 4 into the capsule nest 3. In this case, the capsule is pierced by its lower part of the piercer 7, after which the user screws the claimed device with the installed capsule into the car coffee machine 9, presses the capsule piercer, which is an element of the car coffee machine, to the capsule using a pressing device, for example, a lever. The user turns on the water supply. Water passes through the elements of the car coffee machine using a blower, gets into the upper piercer, into the capsule and flows down as a ready-made drink into the body of the glass. After the glass is filled, the user removes the claimed device from the car coffee machine. The drink is ready for consumption through the drinking hole. After drinking the drink, the user disposes of the claimed device together with the capsule. Thus, the claimed utility model allows to increase the safety of the claimed device.
