Description

The utility model relates to elements of devices for preparing drinks by extracting bulk substances, such as, for example, ground coffee, crushed tea leaves, chocolate powder, milk powder, sugar, cinnamon and others, contained in capsules without an internal piercer. The utility model can be used in a system for the safe preparation of drinks, consisting of the claimed device and a car coffee machine with a scanner, configured to control the type of the claimed device, which can be used as a vending machine for selling drinks mainly in transport and in particular 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 2747104, 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 12/10/2021) [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 06/10/2023). 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 thermos glass is claimed - an external holder of one capsule equipped with an annular shelf and thread, a system for the safe preparation of drinks, consisting of a side wall containing an external thread and an annular shelf, inseparably connected to the inner part of the side wall and configured to hold a piercer ; a piercer containing one piercing element, configured to be installed on the annular shelf and pierce the lower part of the capsule located in the capsule socket; a bottom inseparably connected to the side wall; an annular part containing drinking holes and an internal thread configured to connect with an external thread; a capsule nest made inseparably from the annular part and configured to accommodate one capsule; containing markings capable of being read by a scanner of a car coffee machine; characterized in that it contains a removable annular part containing an internal protrusion configured to be pressed against the inner side of the side wall, and a heat-insulating coating connected to the annular part; an outer flask connected to the top of the side wall; vibration damper containing holes, made inseparable from the internal protrusion on one side and inseparable from the capsule socket on the other side, and designed to damp vibrations of the liquid inside the glass body.

The claimed device is an external capsule holder for a safe beverage preparation system.

The safe preparation system for drinks is a system of elements connected to each other. Elements of the system for the safe preparation of drinks are a car coffee machine 11 equipped with a scanner 12, made with the ability to control the compatibility of the claimed device with the external capsule holder. To prepare a drink using a safe beverage preparation system, a capsule 7 containing a dry substance and water is used.

The claimed device is connected to a car coffee machine 11 using an upper piercer, which is an element of the car coffee machine, which is connected to one capsule placed in the claimed device. Water moves from the car coffee machine to the body of the glass 9, inside the elements of the safe preparation system for drinks. This eliminates an open stream and ensures protection from drink getting on the passenger and the vehicle 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 an external thread 5, which is inseparably connected to the upper edge of the side wall 2. The claimed device contains an annular part 1 containing one or more holes for drinking, and is made with the possibility of connection with the external thread 5 using an internal thread 13. The internal thread 13 is located on the annular part 1, made inseparably from the annular part 1 by casting or gluing and is configured to connect with external thread 5. Accidental disconnection of the annular part 1 and the body of the glass 9 during operation of the claimed device can lead to the spilling of a hot drink on the passenger. The threaded connection 18 of the annular part 1 and the body of the cup 9 is a more reliable connection in comparison with a connection using an annular groove. The use of a threaded connection increases the operational safety of the claimed device.

The annular part 1 is made inseparably with the capsule nest 3 using casting. The capsule nest 3 is designed to accommodate one capsule 7 in such a way that the drink flowing from the capsule 7 enters the body of the glass 9. The capsule nest 3 is designed to allow access and tight pressing of the upper piercer, which is an element of the automobile coffee machine, to the capsule 7 installed in the nest of capsules 3.

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 capsule 7 without an internal piercer (for example, the Nespresso standard), the claimed device contains a piercer 6 containing an annular part with an internal jumper on which one piercing element (for example, a needle) is 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 sharp piercing part of the piercer 6 can pierce the lower part of the capsule 7 when placing the capsule 7 in the capsule nest 3.

Making the piercer in the form of a ring with a jumper and a piercing element, 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 a pin with a piercing part and placing the piercer 6 on the bottom 4, since in the case of placing the piercer 6 at the bottom 4, the piercer has a large length and can bend and deflect when resting against the bottom of the capsule, as a result of which the bottom of the capsule 7 will not be pierced, as a result of which water, which is supplied under pressure from a car coffee machine, may splash through the connection “top pierce - capsule” 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 a piercing element, 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 is 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 cup body 9, a second mold for the production of the piercer 6 and a third mold for the production of the ring part. Thus, we get three products and install the piercer 6 on the ring shelf 8, install the ring part 1 on the body of the glass 9 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 the body of the glass 9. This solution will reduce the number of defects in the production of the claimed device, and, therefore, will reduce the likelihood of using defective claimed devices, which increases the safety of operation of the claimed device, since the claimed device, made with defects, may create a danger, for example, of accidental removal of the ring part 1 from the body of the glass 9 and/or the capsule falling out and/or breakage of the claimed device during the preparation of the drink, as a result of which a hot 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 ring part 1 is made inseparable from the capsule nest 3, which increases the safety of operation of the claimed device by eliminating the possibility of the capsule nest 3 falling out of the ring part 1 or the drink flowing through the connection “capsule nest 3 - ring part 1”, which can lead to the danger of the drink getting in on the user, and, as a result, to burns or stained clothing.

The operational safety of the claimed device is increased by eliminating the possibility of using the claimed device with a car coffee machine that does not correspond to the claimed device, for example, with a car coffee machine designed to prepare multi-component drinks, in which the upper capsule piercer is configured to pierce several capsules simultaneously, the location of which differs from location of the capsule in the claimed device. Supplying water to the upper capsule piercer of an automobile coffee machine 11, configured to prepare multi-component drinks, will cause hot water to splash past the capsules and create a danger of hot water contacting the user and the vehicle interior.

To eliminate such a danger, the claimed device contains marking 10, which can be a barcode or a QR code, which is applied to the claimed device, for example, by painting and/or gluing and/or burning and/or casting and/or stamping or using any another method of application. Marking 10 contains encoded information, for example, about the type of the declared device and/or any other information that allows the automobile coffee machine 11 to identify the declared device as an element that, based on the type and legitimacy of production, can be used with the automobile coffee machine 11. The presence of marking 10 allows you to control the compatibility of the declared device and automobile coffee machine 11, and also allows you to obtain any other information about the declared device, which may be contained in the marking 10. To read the marking 10, the automobile coffee machine contains a scanner 12. The automobile coffee machine is configured to receive and analyze information obtained from the marking 10 and making a decision about the possibility or impossibility of operating the automobile coffee machine 11 together with the proposed claimed device. The analysis of the marking 10 occurs, for example, using the electronic control unit of a car coffee machine, which is designed to analyze the information received from the marking 10 and send a command to the elements of the car coffee machine to prepare a drink or block the process of preparing a drink. Marking 10 can be applied to any place of the claimed device with the ability to read marking 10 by scanner 12. This solution increases the safety of operation of the claimed device.

The safety of operation of the claimed device is increased by reducing the likelihood of accidental removal of the ring part 1 from the body of the glass 9, due to too much squeezing of the side wall 2 by the user, as a result of which a hot drink can spill on the user and/or the car interior while the car is moving in shaking conditions and vibrations.

To reduce the likelihood of such a danger, the claimed device is equipped with an internal projection 14, designed to be pressed against the inside of the side wall 2 when installing the annular part 1 on the body of the cup 9 using a threaded connection 18. The internal projection 14 is located on the lower side of the annular part 1 and made inseparably from the annular part 1, for example, by casting. The inner projection 14 has an annular shape and is configured to press against the inside of the side wall 2. When installing the annular part 1 on the body of the glass 9, the annular part 1 creates pressure on the side wall 2, which transfers the created pressure to the inner projection 14. Internal projection 14 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 the drink. This solution increases the operational safety of the claimed device.

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 drink splashing onto a passenger or elements of the car interior.

To eliminate such a danger, the claimed device contains an outer flask 15, which is inseparably connected to the upper part of the side wall 2, 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 side wall 2 and 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 drink a drink from the body of the glass 9 through the drinking hole, and is also designed to install the ring part 1 on the body of the glass 9. This solution increases the safety of operation of the claimed device.

The drink located in the glass body shakes and splashes due to shaking of the claimed device in the user's hand, since consumption occurs inside a moving car. Increased operational safety of the claimed device can be ensured by increasing the protection against splashing of the drink from the glass body through the drinking hole, since shaking 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 burns.

To protect against such a danger, the claimed device contains a vibration damper 17, which is a horizontal annular platform made inseparable from the internal protrusion, for example, by gluing, on the one hand, and inseparable from the capsule nest 3, for example, by gluing, on the other sides. The vibration damper 17 includes one or more openings configured to allow liquid to pass through such that liquid flows through them and reaches the drinking opening when the user tilts the inventive device for drinking purpose. Most of the liquid splashing inside the glass body when the glass is in a vertical position rests against the vibration damper 17, thus, 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 17 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.

The utility model works as follows.

The user manually installs the piercer 6 on the ring shelf 8, then installs the ring part 1 on the body of the glass 9 using a threaded connection, inserts the capsule 7 into the capsule socket 3, while the capsule 7 is pierced with its lower part by the piercer 6, after which the user places the claimed device in a car coffee machine and presses the upper piercer, using, for example, a lever. The user turns on the water supply. Car coffee machine 11, using scanner 12, reads marking 10, analyzes the information received and sends a command to the elements of car coffee machine 11 to prepare a drink or blocks the process of preparing a drink. 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 capsule through the puncture. Water passes through the capsule 7 and from there, in the form of a 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 the drink from the car coffee machine, the drink is ready for consumption through the drinking hole. After consuming the 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.
