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, which can be used as a vending machine for selling drinks mainly in transport and in particular 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 device is known, a capsule holder-cup 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 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 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 with a heat-insulated external capsule holder is claimed, consisting of a side wall containing a flange; a bottom containing one bracket configured to hold one piercer; 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 one capsule; a piercer configured to pierce the lower part of the capsule, characterized in that it contains a removable annular part, an internal protrusion configured to be pressed against the inner side of the side wall, an outer flask connected to a flange, configured to increase the thermal insulation properties of the side wall and bottom, a thermal insulation coating connected to the annular part, designed to increase the thermal insulation properties of the annular part.

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

The safe preparation system for drinks is a system of elements connected to each other. The elements of the system for the safe preparation of drinks are a car coffee machine 11 not equipped with an internal capsule holder and the claimed device. 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 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 a flange 5, which can have a toroidal shape and is inseparably connected to the top edge side wall 2. The claimed device contains an annular part 1 containing one or more drinking holes, which can be equipped with protective caps, and configured to connect to the flange 5 using, for example, an annular groove. The ring portion 1 is inseparably connected to the capsule seat 3 by, for example, gluing or casting or other joining method.

The claimed device contains a nest of capsules 3, which 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 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 the capsule 7 installed in the capsule socket 3. The claimed device contains one bracket 8 connected to the inside of the bottom 4, for example, by gluing or casting. The bracket 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 capsules 7 without an internal piercer (for example, the Nespresso standard), the claimed device contains one piercer 6, including a piercing element (for example, a needle). 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 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 glass body 9, a second mold for the production of the piercer 6, a third mold for the production of the annular part 1. Thus, we obtain three products and insert the piercer 6 into the bracket 8, install the annular part 1 on the 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/pg1277673pmQmENz0001274576/.

Unlike a known analogue, the claimed device contains a ring part 1, designed to be removably connected to a flange 5. This solution will reduce the amount 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 from the flange 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 be poured out of the body of the glass 9 onto the passenger and/or elements of the car interior.

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 10, 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 10 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 10 has an annular shape and is configured to press against the inside of the side wall 2. When the annular part 1 is installed on the flange 5, the annular part 1 creates pressure on the side wall 2, which transfers the created pressure to the inner protrusion 10. The inner protrusion 10 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.

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 12, made inseparably from the flange, for example, by casting or gluing. The outer flask 12 is made, for example, of plastic or pressed paper. The outer flask 12 is designed to reduce heat loss through the side wall 2 and the bottom 4. The outer flask 12 follows the shape of the outer part of the body of the glass 9, while the walls of the outer flask 12 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 12 is less than the thermal conductivity of paper or plastic, the temperature on the outer surface of the outer bulb 12 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 beverage preparation systems.

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 13, designed to increase the heat-insulating properties. The thermal insulating coating 13 can be made, for example, of metal, plastic or other material with thermal insulation properties. The thermal insulation cover 13 may be attached to the annular portion 1 by gluing or casting or soldering, and may also be attached by mechanical connection, for example, by hook-shaped fasteners or elastic fasteners, or by ring-shaped or spherical snap fasteners, or by another connection option. The thermal insulation coating 13 is designed to provide access for capsules 7 to the capsule nest 3 and to allow drinking 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 flange 5.

This solution increases the operational safety of the claimed device.

The utility model works as follows:

The user manually inserts the piercer 6 into the bracket 8, then installs the ring part 1 on the flange 5, inserts the capsule 7 into the capsule slot 3, while the capsule 7 is pierced with its lower part by the piercer 6, after which the user places the claimed device in the car coffee machine 11 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 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 inventive device is filled, the user removes the upper piercer from the inventive device by 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 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.
