Description

The utility model relates to elements of devices for preparing one-component drinks, such as Americano or espresso, 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 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 capsule holder-cup 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 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 one capsule, equipped with a capsule nest cover 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 configured to hold 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; 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 projection configured to press against the inner side of the side wall; an outer flask connected to the top of the side wall; a capsule socket cover configured to tightly connect to the capsule socket by surprise and fix the capsule in the capsule socket; 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 single-ingredient drink using the system for the safe preparation of single-ingredient drinks, a capsule 7 containing a dry substance and water is 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 body of the glass 9, inside the elements of the system for the safe preparation of single-component 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, 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 be inseparably connected to the top edge of the side wall 2. The claimed device contains an annular part 1 containing one or more holes for drinking, and is configured to connect to the flange 5 using, for example, an annular groove. The annular part 1 is made inseparable from the capsule socket 3 using, for example, gluing or casting.

The claimed device contains a capsule socket 3, inseparably connected to the annular part 1, and configured to accommodate the 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 made with the possibility of access and tight pressing of the upper piercer , which is an element of a car coffee machine, to capsule 7 installed in the socket of capsule 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 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 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 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 the connection “top pierce - 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 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, a third mold for the production of the ring part 1. Thus, we obtain three types of products and install the piercer 6 on the ring shelf 8, install the ring part 1 on flange 5 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. “Handbook of Design Technicians”, in Chapter 8 “Parts made of plastics” it is written: “...Undercuts deteriorate 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, 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, 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 1 from the flange 5 and/or the capsule falling out and/or breakage of the claimed device during the preparation of a one-component drink, as a result of which a hot one-component drink may spill out of the glass body 9 for the passenger and/or elements of the vehicle interior. This solution increases the operational safety of the claimed device.

The operating 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 can spill onto the user and/or the vehicle interior while the vehicle is moving in conditions of shaking and vibration .

To reduce the likelihood of such a danger, the claimed device is equipped with an internal projection 11, 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 11 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 11 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 flange 5, the annular part 1 creates pressure on the side wall 2, which transfers the created pressure to the inner protrusion 11. The inner protrusion 11 can be of any size within the internal volume of the glass body 9. In this way, additional rigidity of the side wall 2 is created, increasing the permissible force created by the user’s fingers while drinking a single-component drink. 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 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 a single-component drink splashing onto a passenger or elements of the car interior.

To eliminate such a danger, the claimed device contains an outer flask 12 connected to the upper part of the side wall, 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 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 on the outer surface of the side wall 2. This reduces the likelihood of burning the user's fingers, thereby increasing operational safety the declared device.

After pouring the drink into the claimed device, part of the hot liquid remains inside the capsule 7, which has a puncture through which the liquid can leak; in addition, when the upper piercer, which is an element of a car coffee machine, is removed, liquid may leak from the upper pierce, which flows down onto the capsule 7. When the claimed device is tilted, this liquid may fall on the user, which may cause burns and may stain the user's clothing and/or the interior of the vehicle.

To protect against such a danger, the claimed device contains a capsule socket cover 13, which is made, for example, of plastic or paper, and may contain a bottom and a wall, while the bottom of the capsule socket cover protects against liquid from the capsule getting onto the user, and the wall allows the cover to be fixed capsule nests in capsule nests. The cover of the capsule socket 13 is designed to be connected to the capsule socket 3 by surprise, eliminating the possibility of liquid flow through this connection, and also protecting against capsules 7 falling out of the capsule socket 3.

This solution protects against hot liquid getting on the user and the vehicle interior, thereby increasing the safety of operation of the claimed device.

The claimed device contains a cover of the annular part 14, configured to be installed on the annular part 1 and containing an annular protrusion 15. Installation of the cover of the annular part 14, covering the annular part 1 with capsule 7 and capsule socket 3, and execution on the inner side surface of the cover of the annular part 14 in its lower part of the annular protrusion 15, which engages with the lower surface of the flanging 5, allows you to fix the flanging 5 in the annular protrusion 15 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 cover of the annular part 14 and its annular protrusion 15 uniformly around the circumference create conditions for elastic deflection of the side surface of the cover of the annular part 14 during installation of the cover. The holes, combined with the holes for drinking and air on the annular part, allow you to drink a drink after installing the cover of the annular part 14.

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 socket 3, while the capsule 7 is pierced with its lower part by the piercer 6. After this, the user places the claimed device in 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 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 single-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 inventive beverage device from the automobile coffee machine, the user manually inserts the capsule socket cover into the capsule socket, covering the spent capsule installed in the capsule socket. The user then installs the ring portion cover 14 onto the ring portion 1 with the capsule 7 and capsule seat 3, aligning the holes on the ring portion cover with the drinking holes on the ring portion. Thanks to the slots made evenly along the circumference on the side surface of the cover of the annular part 14 and the annular protrusion 15, as well as the conical outer side surface of the annular part 1, the annular protrusion 15, when installing the cover of the annular part 14, is deflected and passes the annular part 1 inside the cover of the annular part 14. In this case, the annular protrusion 15 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.
