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 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 two capsules, equipped with an internal protrusion, and an annular shelf, a system for the safe preparation of two-component drinks, consisting of a side wall containing an external thread and an annular shelf integrally connected to the interior 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 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 two capsules, 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 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 two-ingredient beverage preparation system, two capsules 7 are used, one of which contains ground coffee, and the other which may contain milk powder or sugar.

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 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 two 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 car coffee machine, to capsules 7 installed in capsule slot 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 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 and a third mold for the production of the annular part 1. Thus, we obtain three types of products and install the piercer 6 on the annular shelf 8, 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 two-component drink, as a result of which a hot two-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.

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 and the cup body 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 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 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.

The utility model works as follows:

The user manually installs the piercer 6 on the ring shelf 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 nest 3, inserts two capsules 7 into the capsule nest 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 two 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 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 the drink from the car coffee machine, 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.
