Description

The utility model relates to devices for preparing single-ingredient drinks, such as Americano or espresso, using a capsule without an internal piercer. For example, this could be a Nespresso standard capsule. The thermos can be used in a system for the safe preparation of one-component drinks, consisting of this device and a car coffee machine. This system can be used in taxis to sell single-ingredient drinks.

There are several types of capsule holders for coffee machines.

The capsule holder for coffee machines (patent RU 2747134, published April 28, 2021) [1] includes an annular groove for secure installation and fixation of the capsule with coffee extract and a hole for the exit of the finished drink.

A feature of the capsule holder (patent RU 2761895, published on December 13, 2021) [2], which includes a socket for installing a capsule, is the presence of an annular part in it, which contains holes for drinking and air, it is connected to the body of the glass. The cup body consists of side and bottom walls and cannot be separated from the annular part, which in turn is not separated from the socket for installing the capsule.

Both of the above-described known devices (1, 2) have a disadvantage: they cannot use capsules with a bulk product that are not equipped with an internal piercer, for example, Nespresso standard capsules.

The capsule holder (patent RU 219382, published June 13, 2023) has a lower capsule piercer attached to the inside of the bottom. It is designed with a removable connection for easy maintenance.

The known device also has a holder located on the inside of the bottom. It holds the lower capsule piercer.

It should be noted that this device has the disadvantage of being difficult to manufacture. Its shape contains undercuts, which complicates the production process. To create this monolithic holder, a complex mold is required, which may include special elements such as folding punches, compound and sliding dies, and special removal plates. Obviously, a more complex mold leads to an increase in the percentage of defects during the production process.

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 one capsule, equipped with a lid of the annular part, 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 configured to hold a 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 configured to connect to the annular portion and configured to accommodate one capsule; characterized in that it contains a removable annular part; 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.

This system includes a car coffee machine (10), which does not have an internal capsule holder, and the claimed device. To prepare a one-component drink using such a system, you need to use one capsule (7) with dry substance and water.

The claimed device is connected to a car coffee machine (10) using the upper piercer (6), which is an element of the car coffee machine. It connects to one capsule placed in a thermos glass. Water moves from the coffee machine into the body of the glass, and then inside the elements of the safe preparation system. This allows you to avoid spilling a drink inside the car when driving on uneven roads, ensuring the safety of the passenger.

The claimed device is made using advanced technologies that ensure its strength and reliability. It can be made of plastic or paper. The body of the glass is formed by a side wall permanently connected to the bottom. It contains a flange, which may have a toroidal shape and is permanently connected to the upper part of the side wall. The claimed device also includes an annular part with drinking holes, which can be closed with protective caps. The annular part can be connected to the flange and to the capsule socket using an annular groove or other means.

The claimed device has a capsule socket in which one capsule is placed so that the drink flowing from it falls inside the glass. The capsule nest is made with the possibility of easy access to the upper part of the capsule and tight pressing of the upper piercer, which is an element of a car coffee machine, to the capsule.

The claimed device contains an annular shelf (8) shaped like 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 a capsule (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 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 supporting the annular part of the piercer (6) into the annular shelf (8) when placing the piercer ( 6) on the ring shelf (8). The piercer (6) is configured to be installed on the annular 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 socket (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 if the piercer (6) is placed on the bottom (4), the piercer has a large length and can bend and deviate when resting against the lower part of the capsule, as a result of which the lower part of the capsule (7) will not be pierced, which may result in splashing of water, which is supplied under pressure from a car coffee machine, through the connection “top piercer - capsule” or 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 vehicle interior. 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 it, you need to create a mold into which fused plastic is poured. Manufacturing a monolithic holder requires a complex mold that includes various forming elements, such as folding punches and special dies. The claimed device is collapsible; in its manufacture, separate molds are used for each of its parts (cup body (9), piercer (6), ring part (1) and capsule socket (3)). Thus, we get four products. The mechanism for assembling them is as follows: install the piercer (6) on the annular shelf (8), install the annular part (1) on the flange (5) and before use, place the capsule nest (3) in the annular part (1).

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. “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 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 split such a part into two (or more) simple parts...” (Big Encyclopedia of Oil and Gas. P. 330, paragraph 5. URL: https://www.ngpedia.ru/ pg1677673pmQmENz0001274576/.

The difference between the claimed device and known analogues is that it has a ring part that is removably connected to the flange and the capsule socket. This solution helps reduce the likelihood of using defective devices, which increases the safety of operating the thermos glass. Accidental removal of the ring portion from the flange and the capsule falling out while preparing an espresso or Americano may result in the hot drink spilling onto the passenger and/or the vehicle interior. Therefore, this solution mentioned above ensures the safe operation of the device.

The device also includes a ring portion cover with an annular projection. Installing this cover on the annular part covering the capsule and the capsule socket allows you to fix the flange in the annular protrusion, which will prevent the glass from falling out during operation. This also contributes to the safety of using the device, since spilling a hot drink on the passenger and the vehicle interior is avoided. The taper of the outer side surface of the annular part and the presence of through holes located evenly around the circumference on the side surface of the annular part cover (11) and its annular protrusion allow the side surface of the cover to be deflected when installing it. In addition, the presence of drinking and air holes on the ring part allows you to consume the drink after installing the lid.

When using a glass, there is a risk of getting burned or dropping it due to the high temperature of the drink and overheating of the side wall. In addition, there is a danger that hot coffee may spill onto the passenger or other parts of the car.

To eliminate this danger, the inventive device is provided with an outer bulb, which is firmly connected to the upper part of the side wall by casting or gluing. It can be made, for example, from plastic or pressed paper. The outer bulb helps reduce heat loss through the side wall and bottom. Its shape follows the shape of the glass body, but does not touch the bottom.

Since the air between the sidewall and the outer bulb conducts heat less well than paper or plastic, the surface of the outer bulb remains cool compared to the surface of the sidewall. This reduces the risk of burning the user's fingers and ensures safer operation of the device.

The claimed device works as follows:

The user manually installs the piercer (6) onto the ring shelf (8). Next, install the annular part (1) on the flange (5) and insert the capsule socket (3) into the annular part (1). He then places the capsule (7) into the capsule socket (3), where the capsule (7) is pierced using the piercer (6). After this, the user places the inventive device in the car coffee machine (10) and presses the upper piercer, for example, using a lever. Then he turns on the water supply, which, using a supercharger, is supplied to the upper piercer and flows into the capsule through the puncture. The liquid passes through the capsule (7) and from there flows into the glass in the form of a one-component drink. After filling it, the user withdraws the upper piercer by lifting the lever and removes the glass of coffee. The user then installs the ring portion cover (11) onto the capsule ring portion and capsule seat (1) and aligns the holes on the cover with the drinking holes on the ring portion. 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 is connected to the lower surface of the flange (5), thereby fixing the flange (5) with the annular part. After which the coffee is ready to drink and can be drunk through a special hole.

Thus, the claimed utility model makes it possible to increase the safety of operation of the claimed device.
