Description

The utility model relates to elements of devices for preparing three-component drinks, such as, for example, latte or cappuccino with sugar, 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 three-ingredient drinks, consisting of the claimed device and a car coffee machine, which can be used as a vending machine for selling three-ingredient 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 on December 13, 2021) [2], characterized in that it contains an annular part containing holes for drinking and air, connected to the cup body, consisting of side and bottom walls, while 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 contains a lower capsule piercer secured 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 (added from the formula). 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 glass is claimed - an external holder of three capsules, consisting of a side wall containing an external thread; a bottom containing three brackets, each of which is configured to hold one piercer; 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 three capsules; three piercers, each of which is configured to be installed in a bracket and capable of piercing the lower part of the capsule, 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 .

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

The system for the safe preparation of three-component drinks is a system of elements connected to each other. The elements of the system for the safe preparation of three-component drinks are a car coffee machine 10 not equipped with an internal capsule holder and the claimed device. To prepare a three-ingredient drink using the three-ingredient safe preparation system, three 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 three 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 three-component drinks. This eliminates an open stream and ensures protection from the three-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 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, 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 made with the possibility of connection with the external thread 5 using an internal thread 11. The internal thread 11 is located on the annular part 1, is made inseparable from the annular part 1 by casting or gluing and is made with the possibility connections 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 a hot drink being spilled on the passenger. The threaded connection 12 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 ring part 1 is made inseparable from the capsule nest 3, which is designed to accommodate three capsules 7 in such a way that the drink flowing from the capsules 7 enters the glass body 9. The inseparable connection of the ring part 1 and the capsule nest 3 increases the safety of operation of the claimed device, so how the removable connection of the capsule nest 3 and the ring part 1 can lead to accidental disconnection of the ring part 1 and the capsule nest 3 during operation of the claimed device, and this can lead to the pouring of a hot drink from the body of the glass 9 through the resulting hole in the ring part 1. Spilled hot drink the drink may stain and/or burn the user.

The capsule nest 3 is made with the ability to access and tightly press the upper piercer, which is an element of the automobile coffee machine, to the capsules 7 installed in the capsule nest 3. The claimed device contains three brackets 8 connected to the inside of the bottom 4, for example, by gluing or casting. Each of the three brackets 8 is configured to fix the piercer 6 by repeating part of the shape of the piercer 6 with the inner part of the bracket 8. To use three capsules 7 without an internal piercer (for example, the Nespresso standard), the claimed device contains three piercers 6, including a piercing element (for example , igloo). The piercer 6 is designed to be fixed in the bracket 8, so 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 nest of capsules 3.

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 and a third mold for the production of the annular part 1. Thus, we obtain three types of products and insert three piercers 6 into the brackets 8 and install the annular part 1 on glass body 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 the 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 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 body of the glass 9 and/or the capsule falling out and/or breakage of the claimed device during the preparation of a three-component drink, as a result of which a hot three-component drink may spill out of the body 9 glasses per passenger and/or elements of the car interior. This solution increases the operational safety 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.

This solution increases the operational safety of the claimed device.

To reduce the likelihood of such a danger, the claimed device is equipped with an internal protrusion 13, designed to be pressed against the inside of the side wall 2 when connecting the annular part 1 to the body of the cup 9 using a threaded connection 13. The internal protrusion 13 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 13 has an annular shape and is configured to press against the inner part 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 internal projection 13. Internal projection 13 can be of any size within the internal volume of the cup body 9. In this way, additional rigidity of the side wall 2 is created, increasing the permissible force created by the user’s fingers during operation of the claimed device. This solution increases the operational safety 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 14, designed to increase the heat-insulating properties. The thermal insulating coating 14 can be made, for example, of metal, plastic or other material with thermal insulation properties. The thermal insulation cover 14 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 fastenings with ring or spherical snap elements, or by means of another connection option. The thermal insulating coating 14 is designed to provide access for capsules 7 to the nest of capsules 3 and to drink a three-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 body of the glass 9.

The utility model works as follows.

The user manually inserts three piercers 6 into the brackets 8, then screws the ring part 1 onto the body of the glass 9 using a threaded connection 12 so that the piercers 6 are under the holes of the capsule socket 3, inserts three capsules 7 into the capsule socket 3, while the capsules 7 is pierced by its lower part with piercers 6, after which the user places the claimed device in the car coffee machine 10, positioning the claimed device in such a way that the three capsules placed in the claimed device are located under the upper piercer, which is an element of the car coffee machine. Next, the user 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 three capsules 7 and from there, in the form of a three-component drink, flows into the body of the glass 9. After the inventive device is filled, the user moves the upper piercer away from the inventive device, lifting the lever, and manually removes the inventive 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 three-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.
