Description

The utility model relates to elements of devices for preparing four-component drinks, such as, for example, latte or cappuccino with sugar and cinnamon, 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 four-ingredient drinks, consisting of the claimed device and a car coffee machine, which can be used as a vending machine for selling four-ingredient drinks, mainly in taxis.

A device is known, 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 tightly fitting the holder onto drink glass.

A known device is a glass capsule 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 openings for drinking and air, connected to the housing glass, consisting of side and bottom walls, while the body of the glass 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 thermos glass is claimed - an external holder of four capsules, equipped with an internal protrusion, a system for the safe preparation of drinks, consisting of a side wall containing an external thread; a bottom containing four 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 four capsules; four piercers configured to be installed in brackets and capable of piercing the lower parts of capsules installed in the capsule nest, 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; an outer flask connected to the top of the side wall.

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

The system for the safe preparation of four-component drinks is a system of elements connected to each other. The elements of the system for the safe preparation of four-component drinks are a car coffee machine 10, not equipped with an internal capsule holder and the claimed device. To prepare a four-ingredient drink using the safe four-ingredient beverage preparation system, four 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 four 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 four-component drinks. This eliminates an open jet and provides protection from the four-ingredient 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 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 annular part 1 is made inseparable from the capsule nest 3, which is designed to accommodate four capsules 7 in such a way that the drink flowing from the capsules 7 enters the body of the glass 9. The capsule nest 3 is made with the ability to access and tightly press the upper piercer, which is an element automobile coffee machine, to capsules 7 installed in the capsule socket 3. The claimed device contains four brackets 8 connected to the inside of the bottom 4, for example, by gluing or casting. Each of the four 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 four capsules 7 without an internal piercer (for example, the Nespresso standard), the claimed device contains four 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 four types of products and insert four 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 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 a four-component drink, as a result of which a hot four-component drink may be poured out of glass housings 9 for the 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.

The utility model works as follows:

The user manually inserts four 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 four 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 four 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 four capsules 7 and from there, in the form of a four-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 the drink from the car coffee machine, the drink is ready for consumption through the drinking hole. After consuming the four-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.

To reduce the likelihood of such a danger, the claimed device is equipped with an internal projection 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 12. The internal projection 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 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 with a hot drink falling, the four-component drink splashing out on the passenger or elements of the car interior.

To eliminate such a danger, the claimed device contains an outer flask 14, which is inseparably connected to the upper part of the side wall 2, for example, by casting or gluing. The outer flask 14 is made, for example, of plastic or pressed paper. The outer flask 14 is designed to reduce heat loss through the side wall 2 and the bottom 4. The outer flask 14 follows the shape of the outer part of the body of the glass 9.

Since the thermal conductivity of the air between the side wall 2 and the outer bulb 14 is less than the thermal conductivity of paper or plastic, the temperature on the outer surface of the outer bulb 14 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.
