The utility model can be used in a system for safely preparing three-component beverages, consisting of the claimed device and a car coffee machine, which can be used as a vending machine for three-component beverages, primarily in taxis.

A glass is known from the prior art - 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 is 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 - 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 - 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 with the flange; a capsule seat, configured to connect with 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.

A three-capsule external holder with side wall thermal insulation is known from the prior art (RU 222650 U1, patent holder Vitaly Pavlovich Pankratov (RU), publication date 16.01.2024). The three-capsule external holder 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 portion containing drinking holes and configured to be connected to the flange; a capsule seat made inseparable from the annular portion and configured to accommodate three capsules; three piercers, each of which is inseparably connected to the bracket and is designed with the ability to pierce 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 ability to press against the inner side of the side wall, and a grip designed with the ability to fix 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 ability to fix the grips on the flange.

The closest thing to the claimed utility model is a thermos cup - an external holder for two capsules, equipped with grips, clamps and an annular shelf (RU 224877 U1, patent holder Vitaly Pavlovich Pankratov (RU), publication date 04/08/2024). A thermos cup is an external holder for 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 be connected to the flange; a capsule nest adapted to be connected to an annular portion and adapted to accommodate two capsules; containing markings adapted to be read by a scanner of a car coffee machine, characterized in that it comprises a removable annular portion containing grips adapted to fix the annular portion on a flange; an outer flask connected to the flange; a capsule nest containing four locks located on the outer side of the vertical portion of the capsule nest, adapted to fix two capsules installed in the capsule nest.

A drawback of the analogs and prototype is that the cups contain piercing elements located at the bottom of the cup. These piercing elements are long and can bend and deviate when pressed against the bottom of the capsules. If the piercing elements are designed as a ring with crossbars and piercing elements and placed on an annular shelf located on the inside of the side wall of the cup, the piercing elements can bend downward when pressed against the bottom of the capsules. In both cases, the lower portions of the capsules will not be punctured, which could result in hot water, which is supplied under pressure from the car coffee machine, being sprayed out through the “upper piercer - capsules” connection, or in a rupture of the water lines inside the coffee machine, which would also result in a spray of hot water, which could splash onto the passenger, burn them, stain clothes and/or the interior of the car.

Furthermore, in known devices, the cup and lid are joined using a flange on the top of the cup and a semi-tonic shape for the matching flange on the lid body. The disadvantage of this connection is the difficulty of manufacturing the flange on the top of the cup and the semi-tonic shape for the matching flange on the lid body. These elements are complex shapes, requiring the creation of complex molds that include specialized forming elements such as folding punches, composite and sliding dies, and specialized removal plates. Obviously, the more complex the mold, the higher the defect rate.

Thus, the known designs are unsafe to operate.

The technical result achieved by the utility model consists in increasing the operational safety of the claimed device.

In order to achieve the technical result, a glass is claimed - an external holder of three capsules, equipped with a positioner of the annular part, hemispherical protrusions, a drinking straw, an external flask and a rubber seal, 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 three capsule piercers 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 the side wall contains a positioner of the annular part, and the annular part has a mating part of the positioner of the annular part, the outer profile of which repeats the inner profile of the positioner of the annular part, made with the possibility of ensuring the installation of the lid in the glass in a position in which the piercers are located under the openings of the capsule nest, wherein the annular part contains hemispherical protrusions on the outer side, and the side wall contains mating parts of the hemispherical protrusions of the upper part, made with the possibility of fixing the hemispherical protrusions after installing the lid in the glass, wherein the lid contains a drinking tube made inseparable from the lid, wherein 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 by means of a threaded connection, wherein on the upper part of the glass along the perimeter of the inner side there is a rubber seal.

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

The safe beverage preparation system is a system of interconnected components. The components of the safe beverage preparation system are the 9-piece car coffee machine, which is not equipped with an internal capsule holder, and the claimed device.

The claimed device connects to the in-car coffee machine 9 via external thread 8, which is an element of the claimed device, and upper piercers and internal threads, which are elements of the in-car coffee machine. The upper piercers connect to capsules 4 located within the claimed device, and the internal thread of the in-car coffee machine connects to the external thread of the claimed device. Water flows from the in-car coffee machine to the claimed device within the elements of the safe beverage preparation system. This prevents an open stream and ensures protection from liquid spills on the passenger and the vehicle interior during bumpy driving.

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 portion containing a drinking opening and a capsule seat 3, which is configured to accommodate the capsules in such a way that the beverage flowing from the capsule 4 enters the cup 2. The capsule seat is configured to allow access and tight pressing of upper piercers, which are elements of the in-car coffee machine 9, against the capsules installed in the capsule seat. The lid may comprise a stop, which may be an annular protrusion configured to limit the displacement of the lid into the cup.

To connect lid 1 and cup 2, the lid is inserted into the cup using a thrust mechanism. The outer diameter of the lower portion is equal to the inner diameter of the upper portion of the cup. This solution eliminates the need for a flange on the cup and a semi-toriated mating flange on the lid body, improving the safety of the device. These components are complex shapes, requiring the creation of complex molds that include specialized forming elements such as folding punches, composite and sliding dies, and specialized removal plates. Obviously, the more complex the mold, the higher the defect rate, which can lead to component failure or a loose fit. This can lead to the lid being removed from the cup or their loose connection, resulting in a hot beverage spilling from the device onto the user and the vehicle interior. Thus, connecting the lid and cup by means of a thrust mechanism, ensuring the lid is tightly secured in the cup, improves the safety of the device.

The annular portion comprises an external thread 8 on the outer side. The external thread is configured to accommodate a cup 2 with a lid 1 installed on a car coffee machine 9 from below, by screwing the claimed device into the car coffee machine from below, beneath the upper capsule piercers, which are part of the car coffee machine. This eliminates the need for a cup holder, which is part of the car coffee machine. The use of an external thread to connect the claimed device to the car coffee machine increases the safety of the claimed device compared to alternatives, such as a solid or intermittent external projection on the annular portion, or a cup holder, which is part of the car coffee machine. The outer solid or intermittent protrusion on the annular part has a smaller contact area between the outer protrusion and its mating part, which is a component of the in-car coffee machine, than the contact area between the external thread and the mating part. This means there is a higher risk of the outer solid or intermittent protrusion breaking off when the upper capsule piercer presses on the lid. Breaking off the outer protrusion will cause the claimed device to fall out of the in-car coffee machine, causing the hot beverage to splash, scalding the user, and dirtying the car interior. A connection using an external thread reduces this risk, thereby increasing the safety of the claimed device. The cup holder, which is a component of the in-car coffee machine, secures the cup with the lid in place. The pressure created by the upper capsule piercers on the lid is transmitted from the lid to the cup, from the cup to the cup holder, and from the cup holder to the body of the in-car coffee machine. Each of these components can fail due to wear and tear, manufacturing defects, and/or improper installation. The more components in the pressure transmission chain from the upper piercing elements to the car coffee maker body, the higher the risk of failure, which could result in the device falling out of the car coffee maker. A hot beverage could splash, burn the user, and stain the car interior. External threads have a large contact area with the mating part, which is part of the car coffee maker body. In the pressure transmission chain from the upper piercing elements, the external thread directly transfers the generated pressure to the car coffee maker body, eliminating the need for a cup holder and preventing pressure transfer to the cup. Therefore, the use of external threads increases the safety of the device.

The claimed device contains three piercers 7 located inside the body of the cup 2. The piercers are made inseparable from the cup by means of casting or gluing. The piercers have vertical supports with attachment points to the inner side of the bottom 6 and have horizontal struts made inseparable from the inner side of the side wall 5. The implementation of the piercers with horizontal struts, as well as the inseparable connection of the piercers with the body of the cup, increases the safety of the operation of the claimed device in comparison with the embodiment of the piercer in the form of a vertical pin located on the bottom, since such a piercer is longer and can bend and deviate when resting against the lower part of the capsule 4. In the case where 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 portion of the capsule will not be punctured, which could result in a splash of hot water, supplied under pressure from the in-car coffee machine 9, through the "upper piercers - capsules" connection, or a rupture of the water lines inside the in-car coffee machine, which would also result in a splash of hot water that could splash onto the passenger, burn them, stain clothing, and/or the car's interior. Therefore, the design of the piercers, which are integral to the interior of the base and the interior of the side wall, increases the safety of the device.

The claimed device comprises a ring-shaped positioner formed on the side wall of the cup, for example, by casting, gluing, or another method. The ring-shaped portion comprises a mating portion of the ring-shaped positioner, the outer profile of which replicates the inner profile of the ring-shaped positioner. The ring-shaped positioner may be implemented as a protruding or concave element that prevents the lid 1 from being inserted into the cup in any position except for the position in which the mating portion of the ring-shaped positioner enters the ring-shaped positioner. The ring-shaped positioner is configured to ensure that the lid is installed on the cup in a position in which the piercers 7 are located under the openings of the capsule seat. The ring-shaped positioner improves the operational safety of the claimed device, since to ensure the ability to pierce the capsules placed in the capsule seat 3 when inserting the lid into the cup, it is necessary to position the lid in the cup such that the capsules installed in the capsule seat are above the piercers. The lid can be incorrectly positioned if it is inserted into the cup with its axial rotation such that the capsule seat openings are not positioned over the piercers. If the lid is incorrectly positioned in the cup, the piercers will not pierce the bottoms of the capsules. If the bottoms of the capsules are not pierced and the user turns on the water supply, there is a risk of hot water splashing through the connection between the capsules and the upper piercer, which is part of the in-car coffee machine. This can cause the water pumped by the in-car coffee machine to be unable to exit through the openings in the bottoms of the capsules. This could cause hoses to rupture inside the coffee machine, or a hose to be removed from a component of the coffee machine, such as the heater or pump. This could also result in a spray of hot water under pressure, which could hit interior components of the car and/or the user, scalding them and staining their clothing. The ring positioner eliminates this risk, thereby increasing the safety of the device.

The claimed device comprises hemispherical projections made of the same material as lid 1, formed inseparably from the outer surface of the annular portion by casting, gluing, or other means. Sidewall 5 of cup 2 comprises mating portions of the hemispherical projections, which may be, for example, openings or hemispherical recesses, the diameter of which is equal to the diameter of the hemispherical projections. The hemispherical projections engage the mating portions of the hemispherical projections when the lid is inserted into the cup. The hemispherical projections are designed to secure the lid in the cup. The presence of the hemispherical projections prevents the lid from being accidentally removed from the cup, which could result in a hot beverage from the claimed device spilling onto the user. Thus, the hemispherical projections enhance the operational safety of the claimed device.

The claimed device comprises a drinking straw, integrally molded or bonded to the lid 1. The drinking straw allows for drinking from the claimed device. The drinking straw may be integrally molded to any part of the lid. The drinking straw is made of the same material as the claimed device. The length of the portion of the drinking straw located inside the claimed device is 1-2 mm shorter than the height of a glass, allowing the entire volume of beverage contained within the claimed device to be consumed. The integral connection between the drinking straw and the lid improves the safety of the claimed device by eliminating the gap in the drinking opening between the drinking straw and the annular portion, as is present with traditional straws. A hot beverage could splash through this gap, scalding and staining the passenger. Furthermore, when using traditional straws that are not secured to the cap and inserted into the drinking hole, there is a risk of accidentally removing the straw from the drinking hole, leaving a hot beverage exposed and creating the risk of splashing the hot beverage through the drinking hole during bumpy driving conditions. Furthermore, a drinking straw allows for drinking without tilting the glass, which also improves the safety of the device. When tilting the device, the liquid exerts pressure on the capsule and ring from the inside, creating the risk of the capsule or ring falling out, which could result in a hot beverage spilling onto the user and/or the vehicle interior. Thus, a drinking straw improves the safety of the device.

The beverage poured into the device is hot, and high heat transfer through the side wall causes the heat to build up on the outer surface of the side wall. This could result in burns to the passenger's fingers and the device falling if the passenger instinctively opens their fingers. This could create a risk of the device falling with the hot beverage, splashing the beverage onto the passenger and/or interior of the vehicle.

To reduce this risk, the claimed device comprises an outer bulb with an internal thread on the top. The outer sidewall has an external thread designed to connect to an internal thread on the outer bulb. The outer bulb is connected to the sidewall via a threaded connection. The outer bulb is made, for example, of plastic. The outer bulb follows the shape of the outer sidewall and bottom. When mounted on the sidewall, the outer bulb does not touch the sidewall or bottom, creating an air gap between the outer bulb and the sidewall. Since the thermal conductivity of the air between the sidewall and the outer bulb is lower than that of the plastic, the temperature on the outer surface of the outer bulb is lower than that on the outer surface of the sidewall. This reduces the risk of burning the user's fingers, thereby increasing the safety of the claimed device.

The use of a threaded connection between the outer bulb and the side wall improves the operational safety of the claimed device, compared to solutions in which the outer bulb is integral to the side wall. This is because the claimed device is manufactured using injection molding, requiring the creation of a mold into which molten plastic is injected under pressure. A monolithic connection between the outer bulb and the side wall requires a complex mold, which may include specialized forming elements such as folding punches, composite and sliding dies, and specialized removal plates. Obviously, the more complex the mold, the higher the defect rate. In the "Great Encyclopedia of Oil and Gas", citing the book by Ya. A. Samokhvalov "Handbook of a Design Technician", in Chapter 8 "Parts made of plastics" it is written: "...Undercuts impair 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 operation of the declared device, since the declared device, manufactured with a defect, can create a hazard, for example, the 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 vehicle interior.

The tighter the fit of the lid to the glass, the better the protection against hot beverage leakage from the glass when the claimed device is tilted while drinking the beverage and/or during shaking while driving. The contact area of the lid and the glass is maximum when the diameter of the outer side of the lower part of the lid matches the diameter of the inner side of the upper part of the glass. However, if a manufacturing defect was allowed during the claimed device, resulting in a change in the diameter of the outer side of the lower part of the lid and/or the diameter of the inner side of the upper part of the glass, or if, after careless transportation and/or storage of the lid and/or glass, deformations of the lid and/or glass occurred, resulting in a change in the diameter of the outer side of the lower part of the lid and/or the diameter of the inner side of the upper part of the glass, the contact area of the lid and the glass will decrease, gaps may appear between the lid and the glass, which may lead to a hot beverage leakage from the glass through the formed gaps when the claimed device is tilted while drinking the beverage and/or during shaking while driving. A leaking hot beverage can burn and/or stain a passenger. To protect against this hazard, the device includes a rubber seal at the top of the cup, located around the circumference of the inner side wall and bonded to the side wall. The rubber seal is made of a soft rubber material and allows the lid to be inserted into the cup and sealed. The rubber seal prevents the hot beverage from leaking from the cup when the device is tilted while drinking or during vehicle vibrations, thereby increasing the safety of the device.

The utility model works as follows:

The user manually inserts lid 1 into cup 2. The user inserts capsules 4 into capsule slot 3. The capsules are pierced at the bottom by the piercers. The user then screws the device with the capsules into car coffee maker 9 and presses the capsule piercers, which are part of the car coffee maker, against the capsules using a pressing device, such as a lever. The user turns on the water supply. Water flows through the car coffee maker's components via a pump, enters the upper piercers, enters the capsules, and flows as a finished beverage into the body of the cup. Once the cup is filled, the user removes the device from the car coffee maker. The beverage is ready for consumption through the drinking hole. After consumption, the user disposes of the device along with the capsules. Thus, the claimed utility model improves the operational safety of the claimed device.
