Description

The utility model relates to elements of devices for preparing two-component drinks, such as, for example, latte or cappuccino, by extracting the bulk substance contained in capsules without an internal piercer, such as, for example, Nespresso standard capsules. The utility model can be used in a system for the safe preparation of two-component drinks, consisting of the claimed device and a car coffee machine, which can be used as a vending machine for selling two-component drinks, mainly in taxis.

A known device is a capsule holder for coffee machines, including a socket for installing a capsule with a drink extract and a hole for exiting the finished drink (patent RU 2747134, published on April 28, 2021) [1], characterized by the fact that the capsule holder has an annular groove for tight fitting drink glass holder.

A known device is a capsule glass holder for devices for preparing drinks, including a socket for installing a capsule, (patent RU 2761895, published 12/13/2021) [2], characterized in that it contains an annular part containing holes for drinking and air, connected with a cup body consisting of side and bottom walls, wherein the cup body is inseparable from the annular part, which is inseparable from the socket for installing the capsule. The disadvantage of the known devices [1, 2] is the impossibility of using a capsule with a bulk product that is not equipped with an internal piercer - for example, a Nespresso standard capsule.

A capsule glass holder for devices for preparing drinks is known, including a socket for installing the capsule (patent RU 219382, published 06/13/2023). The solution comprises a lower capsule piercer fixed to the inner part of the bottom, configured to be removably connected, and a holder placed on the inner part of the bottom, configured to hold the lower capsule piercer. The disadvantage of this device is the complexity of manufacturing, since it is a complex figure having a combination of undercuts, its production in a monolithic design will require the manufacture of a complex mold, which may include special forming elements such as folding punches, composite and sliding dies and special removal plates. Obviously, the more complex the mold, the higher the defect rate.

The technical result achieved by the utility model is to increase the operational safety of the claimed device.

To achieve the technical result, a heat-insulated thermos glass is claimed - an external holder of two capsules, equipped with an internal protrusion and an annular shelf, 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 pierce the lower parts of two capsules located in the capsule nest; a bottom inseparably connected to the side wall; an annular part containing holes for drinking and configured to connect with the flange; a capsule nest, made inseparably from the annular part and configured to accommodate two capsules, containing a vibration damper, inseparably connected to the capsule nest on one side and with an internal protrusion, on the other hand, characterized in that it contains a removable annular part containing a thermal insulation coating, and an inner projection configured to press against the inner side of the side wall; an outer flask connected to the top of the side wall; a cover of the annular part containing holes aligned with drinking holes on the annular part, covering the annular part with capsules and a nest of capsules, containing an annular protrusion on the inner side surface in the lower part, engaging with the lower surface of the flange, while the outer side surface is annular The part has a taper, and on the side surface of the cover of the annular part and its annular protrusion, through slots are made evenly around the circumference.

The claimed device is an element of a system for the safe preparation of two-component drinks.

The system for the safe preparation of two-component drinks is a system of elements connected to each other. The elements of the system for the safe preparation of two-component drinks are a car coffee machine 10, not equipped with an internal capsule holder and the claimed device. To prepare a two-ingredient drink using the safe preparation of two-ingredient drinks, two capsules 7 containing dry matter and water are used.

The claimed device is connected to a car coffee machine 10 using an upper piercer, which is an element of the car coffee machine, which is connected to two capsules placed in the claimed device. Water moves from the car coffee machine to the body of the glass 9, inside the elements of the system for the safe preparation of two-component drinks. This eliminates an open stream and provides protection from the two-component drink getting on the passenger and the car interior during a trip in shaking conditions.

The claimed device can be made, for example, of plastic and/or paper, contains a side wall 2, inseparably connected to the bottom 4, which form the body of the glass 9. The side wall 2 contains a flange 5, which can have a toroidal shape, and is inseparably connected to the top edge of the side wall 2. The claimed device contains an annular part 1 containing one or more holes for drinking, and is configured to connect to the flange 5 using, for example, an annular groove. The annular part 1 is made inseparable from the capsule seat 3 using, for example, gluing or casting.

The claimed device contains a nest of capsules 3, which is designed to accommodate two capsules 7 in such a way that the drink flowing from the capsules 7 enters the body of the glass 9. The nest of capsules 3 is made with the ability to access and tightly press the upper piercer, which is an element of a car coffee machine, to capsules 7 installed in the capsule nest 3. The inseparable connection of the ring part 1 and the capsule nest 3 increases the safety of operation of the claimed device, since the removable connection of the capsule nest 3 and the ring part 1 can lead to accidental separation of the ring part 1 and the capsule nest 3 in the process operation of the claimed device, and this may lead to the pouring of a hot drink from the body of the glass 9 through the formed hole in the annular part 1. A spilled hot drink may stain and/or burn the user.

The claimed device contains an annular shelf 8 having the shape of a ring, the outer diameter of which is equal to the inner diameter of the side wall 2 at the point of contact of the side wall 2 with the annular shelf 8. The annular shelf 8 is connected to the inner part of the side wall 2, for example, by gluing or casting. To use capsules 7 without an internal piercer (for example, the Nespresso standard), the claimed device contains a piercer 6 containing a ring part with an internal jumper on which two piercing elements are attached. The diameter of the annular shelf 8 is equal to the diameter of the annular part of the piercer 6, thus, the annular shelf 8 is designed to hold the piercer 6 by means of the annular part of the piercer 6 resting on the annular shelf 8 when placing the piercer 6 on the annular shelf 8. The piercer 6 is designed to be installed on ring shelf 8, such that the two sharp piercing parts of the piercer 6 can pierce the lower parts of the two capsules 7 when placing the two capsules 7 in the capsule nest 3.

Making the piercer in the form of a ring with a jumper and two piercing elements, as well as placing the piercer 6 on the annular shelf increases the safety of operation of the claimed device in comparison with the embodiment of the piercer in the form of two pins with piercing parts and placing them on the bottom 4, since in the case of placement piercers 6 at the bottom 4, the piercers are long and can bend and deflect when resting against the lower parts of the capsule, as a result of which the lower parts of the capsules 7 will not be pierced, as a result of which water, which is supplied under pressure from a car coffee machine, may splash through connection “top piercer - capsules” or to rupture of water lines inside the car coffee machine, which will also lead to splashing of hot water, which can get on the passenger, burn him, stain clothes and/or the interior of the car. Thus, making the piercer 6 in the form of a ring with a jumper and piercing elements, as well as placing the piercer 6 on the annular shelf 8, increases the safety of operation of the claimed device.

The claimed device is manufactured using injection molding, for example, using an injection molding machine. To produce the claimed device, it will be necessary to make a mold into which molten plastic material is poured under pressure. Unlike solution [3], made monolithic, the production of which requires a complex mold, which may include special form-building elements, such as folding punches, composite and sliding dies and special removal plates, the claimed utility model is made collapsible, with using one mold for the production of the glass body 9, a second mold for the production of the piercer 6, a third mold for the production of the ring part 1. Thus, we obtain three products and install the piercer 6 on the ring shelf 8, install the ring part 1 on flange 5 before use.

Obviously, the more complex the mold, the higher the defect rate. In the “Great Encyclopedia of Oil and Gas” with reference to the book by Samokhvalov Y.A. “Handbook of Design Technicians”, 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 mold and limit productivity during pressing. By changing the design of products, undercuts can be avoided. If it is impossible to avoid undercuts, then in some cases it is advisable to divide such a part into two (or more) simple parts...” p. 330, para. 5. https://www.ngpedia.ru/pg1677673pmQmENz0001274576/.

Unlike a known analogue, the claimed device contains a ring part 1 made with the possibility of removable connection with a flange 5. This solution will reduce the amount of defects in the production of the claimed device, and, therefore, reduce the likelihood of using defective claimed devices, which increases the safety of operation of the claimed device, so how the claimed device, made with defects, can create a danger, for example, of accidental removal of the ring part 1 from the flange 5 and/or the capsule falling out and/or breakage of the claimed device during the preparation of a two-component drink, as a result of which a hot two-component drink may spill out of the glass body 9 for the passenger and/or elements of the vehicle interior. This solution increases the operational safety of the claimed device.

The operational safety of the claimed device is increased by reducing the likelihood of accidental removal of the annular part 1 from the flange 5 due to too much squeezing of the side wall 2 by the user, as a result of which a hot drink may spill onto the user and/or the vehicle interior while the vehicle is moving in shaking conditions and vibrations.

To reduce the likelihood of such a danger, the claimed device is equipped with an internal projection 11, designed to be pressed against the inside of the side wall 2 when installing the annular part 1 on the flange 5. The internal projection 11 is located on the lower side of the annular part 1 and is made inseparable from the annular part 1 , for example, using casting. The inner protrusion 11 has an annular shape and is designed to be pressed against the inner part of the side wall 2. When installing the annular part 1 on the flange 5, the annular part 1 creates pressure on the side wall 2, which transfers the created pressure to the inner protrusion 11. The inner protrusion 11 can be of any size within the internal volume of the glass body 9. Thus, additional rigidity of the side wall 2 is created, increasing the permissible force created by the user’s fingers while drinking a two-component drink. This solution increases the operational safety of the claimed device.

The drink in the glass body splashes due to the shaking and maneuvering of a moving car. Increased operational safety of the claimed device can be ensured by increasing the protection against spilling of the drink from the glass body through the drinking hole, since splashing of the drink inside the glass body can lead to the drink splashing out through the drinking hole and the hot drink getting into the user’s hands, which can lead to burn.

To protect against such a danger, the claimed device contains a vibration damper 12, which is a horizontal annular platform made inseparable from the internal protrusion on one side and inseparable from the capsule socket 3 on the other side, for example, by gluing or casting. The vibration damper 12 includes one or more openings configured to allow liquid to pass through such that liquid flows through them and enters the drinking opening when the user tilts the inventive device for drinking purposes. Most of the liquid splashing inside the glass body when the glass is in a vertical position rests on the vibration damper 12, so that splashes of liquid do not reach the drinking hole, but that part of the liquid that passes through the holes of the vibration damper when the liquid splashes inside the body glass, loses momentum and flows back. The vibration damper 12 is designed to damp vibrations of the liquid inside the body of the glass 9 and reduce the likelihood of liquid splashing through the drinking holes. This solution increases the operational safety of the claimed device.

The claimed device contains a cover of the annular part 13, configured to be installed on the annular part 1 and containing an annular protrusion 14. Installation of the cover of the annular part 13, covering the annular part 1 with capsules 7 and a nest of capsules 3, and execution on the inner side surface of the cover of the annular part 13 in its lower part of the annular protrusion 14, which engages with the lower surface of the flanging 5, allows you to fix the flanging 5 in the annular protrusion 14 and thereby prevent the cup body from falling out of the annular part during operation of the claimed device. This increases the safety of operation of the claimed device, since the fall of the glass body from the annular part will lead to the spilling of the hot drink located in the glass body and the hot drink getting on the passenger and the vehicle interior. The taper of the outer side surface of the annular part 1 and the execution of through slots on the side surface of the cover of the annular part 13 and its annular protrusion 14 uniformly around the circumference create conditions for elastic deflection of the side surface of the cover of the annular part 13 during installation of the cover. The holes, combined with the holes for drinking and air on the annular part, allow you to consume a drink after installing the cover of the annular part 13.

The drink poured into the claimed device has a high temperature, and the large heat transfer through the side wall 2 leads to the fact that a high temperature is formed on the outer surface of the side wall 2. This can lead to burns of the passenger's fingers and the fall of the claimed device when instinctively unclenching the fingers, this can lead to there is a danger of the claimed device containing a hot drink falling, or the two-component drink splashing onto a passenger or elements of the car interior.

To eliminate such a danger, the claimed device contains an outer flask 15 connected to the upper part of the side wall, for example, by casting or gluing. The outer flask 15 is made, for example, of plastic or pressed paper. The outer flask 15 is designed to reduce heat loss through the side wall 2 and the bottom 4. The outer flask 15 follows the shape of the outer part of the body of the glass 9, while the walls of the outer flask 15 do not touch the bottom 4.

Since the thermal conductivity of the air between the side wall 2 and the outer bulb 15 is less than the thermal conductivity of paper or plastic, the temperature on the outer surface of the outer bulb 15 is lower than that on the outer surface of the side wall 2, this reduces the possibility of burning the user's fingers, thereby increasing safety operation of the claimed device.

The drink poured into the claimed device has a high temperature, and high heat transfer through the annular part 1 leads to the fact that a high temperature is formed on the outer surface of the annular part. This may result in a risk of burns to the passenger's fingers or parts of the face if the passenger touches the outside of the ring portion.

To eliminate such a danger, the annular part 1 contains a heat-insulating coating 16, designed to increase the heat-insulating properties. The thermal insulation coating 16 can be made, for example, of metal, plastic or other material with thermal insulation properties. The thermal insulation cover 16 may be attached to the annular portion 1 by gluing or casting or soldering, and may also be attached by a mechanical connection, for example, using hook-shaped fasteners or elastic fasteners, or fasteners with ring or spherical snap elements, or by using another connection option. The thermal insulation coating 16 is designed to provide access for capsules 7 to the capsule nest 3 and to allow drinking a two-component drink from the body of the glass 9 through the drinking hole, and is also designed to install the ring part 1 on the flange 5. This solution increases the safety of operation of the claimed device.

The utility model works as follows.

The user manually installs the piercer 6 on the annular shelf 8, then installs the ring part 1 on the flange 5, positioning it in such a way that the holes of the capsule nest are located above the piercers 6, inserts two capsules 7 into the capsule nest 3, while capsules 7 are pierced with their lower parts piercers 6, after which the user places the claimed device in the car coffee machine 10 and presses the upper piercer using, for example, a lever. The user turns on the water supply. Using a water pump, water is supplied to the upper piercer, which is configured to allow water passing through the upper piercer to flow into the capsules through the puncture. Water passes through two capsules 7 and from there, in the form of a two-component drink, flows into the body of the glass 9. After the claimed device is filled, the user removes the upper piercer from the claimed device, lifting the lever, and manually removes the claimed device with the drink. After removing the claimed device with a drink from the car coffee machine, the user installs the cover of the annular part 13 on the annular part 1 with capsules 7 and the capsule nest 3, while aligning the holes on the cover of the annular part with the drinking holes on the annular part. Thanks to the slots made evenly along the circumference on the side surface of the cover of the annular part 13 and the annular protrusion 14, as well as the conical outer side surface of the annular part 1, the annular protrusion 14, when installing the cover of the annular part 13, deflects and passes the annular part 1 inside the cover of the annular part 13. In this case, the annular protrusion 14 returns to its initial position under the action of elastic forces and engages with the lower surface of the flange 5, thereby ensuring the fixation of the connection of the flange 5 with the annular part 1. The drink is ready for consumption through the drinking hole. After consuming the two-component drink, the user disposes of the claimed device.

Thus, the claimed utility model makes it possible to increase the safety of operation of the claimed device.
