Description

The utility model relates to devices for preparing one-component drinks, such as, for example, Americano or espresso, by extracting the bulk substance contained in a capsule without an internal piercer, such as, for example, a Nespresso standard capsule. The utility model can be used in a system for the safe preparation of single-ingredient drinks, consisting of the claimed device and a car coffee machine, which can be used as a vending machine for selling single-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 the exit of 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 on December 13, 2021) [2], characterized by the fact that it contains an annular part containing holes for drinking and air, connected to the body of the 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 to be an external holder of one capsule with a lid of the annular part, equipped with a heat-insulating coating, consisting of a side wall containing a flange; a bottom containing one bracket, which is configured to hold one piercer; an annular part containing holes for drinking and configured to connect with the flange; a capsule nest configured to connect to the annular portion and configured to accommodate one capsule; a piercer configured to be placed in a bracket and pierce a capsule placed in a nest of capsules, characterized in that it contains a removable annular part equipped with a heat-insulating coating; an outer flask connected to the top of the side wall; a cover of the annular part containing holes aligned with drinking holes on the annular part, covering the annular part with a capsule and a capsule socket, containing an annular protrusion on the inner side surface in the lower part, engaging with the lower surface of the flange, while the outer side surface is annular The part has a taper, and on the side surface of the cover of the annular part and its annular protrusion, through slots are made evenly around the circumference.

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

The system for the safe preparation of one-component drinks is a system of elements connected to each other. The elements of the system for the safe preparation of single-component drinks are a car coffee machine (10), not equipped with an internal capsule holder, and the claimed device. To prepare a one-ingredient drink using the safe one-ingredient drink preparation system, one capsule (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 a capsule placed in the claimed device. Water moves from the car coffee machine into the glass body (9) inside the elements of the system for the safe preparation of single-ingredient drinks. This eliminates an open stream and ensures protection from single-component drinks 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, and contain 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 may have a toroidal shape, and is inseparably connected to the upper edge of the 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 be connected to a flange (5) using, for example, an annular groove. The annular part (1) is configured to be connected to the capsule socket (3) using, for example, an annular groove or another connection method.

The claimed device contains a capsule socket (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 capsule socket (3) is designed to be accessible and pressed tightly 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 inner part 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 a capsule (7) without an internal piercer (for example, the Nespresso standard), the claimed device contains one piercer (6), which has a piercing element (for example, a needle). The piercer (6) is designed to be fixed in the bracket (8) in this way that the sharp piercing portion of the piercer (6) may pierce the bottom of the capsule (7) when placing the capsule (7) in the capsule socket (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 to produce the cup body (9), a second mold to produce the piercer (6), a third mold to produce the ring part (1) and a fourth mold to produce the capsule seat (3). Thus, we get four products and insert the piercer (6) into the bracket (8), install the ring part (1) on the flange (5) and the capsule socket (3) in the ring part (1) before use.

Obviously, the more complex the mold, the higher the defect rate. In the “Big Encyclopedia of Oil and Gas” with reference to the book by Samokhvalov Y.A. “The Design Technician’s Handbook” in Chapter 8 “Parts Made of Plastics” says: “...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 the known analogue, the claimed device contains a ring part (1), made with the possibility of removable connection with the flange (5) and with the possibility of removable connection with the capsule socket (3). Such a solution will reduce the number of defects in the production of the claimed device, and, therefore, will reduce the likelihood of using defective declared devices, which increases the safety of operation of the claimed device, since a claimed device made with defects may create a danger, for example, of accidental removal of the annular part (1) from flanging (5) and/or falling out of the capsule and/or breakdown of the claimed device during the preparation of a one-component drink, as a result of which a hot one-component drink may be poured from the body of the glass (9) onto the passenger and/or elements of the car interior. This solution increases the operational safety of the claimed device.

The claimed device contains a cover of the annular part (11), configured to be installed on the annular part (1) and containing an annular protrusion (12). Installing the cover of the annular part (11), covering the annular part (1) with the capsule (7) and the capsule socket (3), and making on the inner side surface of the cover of the annular part (11) in its lower part an annular protrusion (12) included in engagement with the lower surface of the flange (5), allows you to fix the flange (5) in the annular protrusion (12) and thereby prevent the cup body from falling out of the annular part during operation of the claimed device. This increases the safety of operation of the claimed device, since the fall of the glass body from the annular part will lead to the spilling of the hot drink located in the glass body and the hot drink getting on the passenger and the vehicle interior. The taper of the outer side surface of the annular part (1) and the execution of through slots on the side surface of the annular part cover (11) and its annular protrusion (12) uniformly around the circumference create conditions for elastic deflection of the side surface of the annular part cover (11) during installation of the cover. The holes, aligned with the drinking and air holes on the annular part, allow you to drink a drink after installing the ring part cover (11).

The drink poured into the claimed device has a high temperature, and high 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 to the passenger's fingers and the claimed device falling when the fingers are instinctively unclenched; this can lead to the danger of the claimed device falling with a hot drink, splashing out a single-component drink on the passenger or elements of the car interior.

To eliminate such a danger, the claimed device contains an outer flask (13) made inseparably from the upper part of the side wall, for example, by casting or gluing. The outer flask (13) is made, for example, of plastic or pressed paper. The outer flask (13) is designed to reduce heat loss through the side wall (2) and bottom (4). The outer flask (13) follows the shape of the outer part of the glass body (9), while the outer flask (13) does not touch the bottom (4).

Since the thermal conductivity of the air between the side wall (2) and the outer bulb (13) is less than the thermal conductivity of paper or plastic, the temperature on the outer surface of the outer bulb (13) is lower than on the outer surface of the side wall (2). This reduces the likelihood of burning the user's fingers, thereby increasing the safety of operation 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 insulation 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 mechanical connection, for example, using hook-shaped fasteners or elastic fasteners, or fasteners with ring or spherical snap elements , or using another connection option. The thermal insulation coating (14) is made with the ability to provide access to the capsule (7) to the capsule socket (3) and with the possibility of drinking a one-component drink from the glass body (9) through the drinking hole, and is also made with the ability to install the annular part (1) on the flange (5). This solution increases the operational safety of the claimed device.

The utility model operates as follows: the user manually inserts the piercer (6) into the bracket (8), then installs the ring part (1) onto the flange (5), inserts the capsule socket (3) into the ring part (1), inserts the capsule (7) into the capsule socket (3), while the capsule (7) is pierced with its lower part by a piercer (6). After this, the user places the inventive device into the car coffee machine (10) 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 drain water passing through the upper piercer into the capsule through the puncture. Water passes through the capsule (7) and from there, in the form of a one-component drink, flows into the body of the glass (9). Once the inventive device is filled, the user moves the top piercer away from the inventive device, lifts the lever and manually removes the inventive device with the drink. After removing the claimed device with a drink from a car coffee machine, the user installs the cover of the annular part (11) on the annular part (1) with the capsule (7) and the capsule socket (3), while aligning the holes on the cover of the annular part with the drinking holes on the annular part . Thanks to the slots made evenly around the circumference on the side surface of the annular part cover (11) and the annular protrusion (12), as well as the conical outer side surface of the annular part (1), the annular protrusion (12) when installing the annular part cover (11) is deflected and passes the annular part (1) inside the cover of the annular part (11). In this case, the annular protrusion (12) returns to its initial position under the action of elastic forces and engages with the lower surface of the flange (5), thereby ensuring the fixation of the connection of the flange (5) with the annular part (1). The drink is ready to drink through the drinking hole. After consuming the one-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.
