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 a taxi.

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 a technical result, a heat-insulated glass is claimed - an external capsule holder, equipped with protection against removal from the glass, latches and an annular shelf, a system for the safe preparation of drinks, consisting of a side wall containing a flange and an annular shelf, inseparably connected to the inner part of the side wall and made with the ability to hold the 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 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, 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, grips configured to fix the annular part on the flange, and a thermal insulation coating connected to the annular portion; a capsule socket containing three latches inseparably connected to the vertical part of the capsule socket, configured to fix the capsule installed in the capsule socket.

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. Elements of the system for safe preparation of drinks are a car coffee machine 13 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 13 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 capsule 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 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 configured 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 part 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 connection “top piercer - 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 glass body 9, a second mold for the production of the piercer 6, a third mold for the production of the ring part 1. Thus, we obtain three products and install the piercer 6 on the ring shelf 8, install the ring 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/pg1677673pmQmENz0001274576/.

Unlike a known analogue, the claimed device contains a ring part 1 made with the possibility of removable connection with a flange 5. 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 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. This creates additional rigidity of the side wall 2, increasing the permissible force created by the user’s fingers while drinking the drink.

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, as this can lead to spilling of the drink on the user and the vehicle interior in shaking conditions while the vehicle is moving.

To reduce the likelihood of such a hazard, the annular part 1 of the claimed device contains one or more grips 11, which are made inseparable from the annular part 1 by stamping or casting, or gluing or another method of connection, and can also be made of plastic. The grips 11 are shaped to bend around the flange 5 during the installation of the annular part 1 on the flange 5 and with the possibility of fixing on the flange 5 during the final installation of the annular part 1 on the flange 5, thus making it difficult to remove the annular part 1 from the flange 5. Grip 11 may have the shape of a wedge or any other shape with an inclined plane, made with the ability to move the grip 11 against the flange 5 and press the grip 11 to the flange 5, grasping the flange 5 when installing the annular part 1 on the flange 5. The presence of grips 11 reduces the likelihood of removing the annular part 1 from flange 5.

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 12, designed to increase the heat-insulating properties. The thermal insulation coating 12 can be made, for example, of metal, plastic or other material with thermal insulation properties. The thermal insulation cover 12 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 means of another connection option. Thermal insulating coating 12 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 flange 5. This solution increases the safety of operation of the claimed device.

When drinking a drink, the capsule 7 is located in the slot of the capsule 3. When drinking a drink, the inventive device with the installed capsule 7 tilts to allow the drink to access the drinking hole, and to allow the drink to be drunk. Thus, capsule 7 moves from a horizontal position to an inclined one and creates the possibility of capsule 7 being displaced or falling out of the capsule socket 3. In addition, the drink located inside the glass body 9 can press on the capsule from below, which increases the risk of capsule 7 falling out of the capsule socket 3 The loss of capsule 7 from the socket of capsule 3, in a moving car, creates the possibility of a hot drink spilling from the body of the glass 9, and getting it on the passenger and elements of the car interior, which can lead to burns, as well as stain the passenger’s clothes and the car interior.

To eliminate such a danger, the claimed device is equipped with three latches 14 located on the outside of the vertical part of the capsule socket 3, made inseparable from the capsule socket 3 by gluing or casting. The latches 14 are designed to prevent the capsule 7 from falling out of the socket of the capsule 3. The latches 14 are made in the form of protruding elements, such as, for example, a hemisphere. The latches 14 are designed to ensure installation of the capsule 7 into the socket of the capsule 3, and to prevent the capsule 7 from falling out of the socket of the capsule 3. The latches 14 are designed to hold the capsule 7 by the upper edge. This solution increases the operational safety of the claimed device.

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 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 13 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 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.
