Description

FIELD OF THE INVENTION

The present invention relates to a device for packaging a solid granular substance used for preparing a beverage directly in a package by immersion in a liquid, in particular for producing beverages by brewing from products such as granulated or ground coffee, tea leaves or tea dust, herbs, etc. P.

State of the art

Known packaging devices designed to improve the convenience of preparing brewed beverages in public catering, offices, etc.

So, it is known the device of the extraction bag (patent RU 2511497 C1, 04/10/2014), comprising a body formed by a flexible material, and the coating material on the outer surface is combined with it by the extreme sections formed on a pair of its opposite edges. The bag has spotted sealing portions, at least one of which is located on both inner sides of the end portions and connects the coating and packaging materials, as well as two hanging threads, the sides of the main ends of which are fixed in the bag body or coating material to form the sealing portions of the main end . The extraction bag is squeezed by pulling the hanging threads in opposite directions.

Despite the possibility of spinning, the design of this device does not allow at the end of the tea brewing process to provide a simple and quick extraction of the used bag from tableware and its movement to the place of local disposal, which leads to inconvenience.

Known tea bag-stick for brewing (patent for the invention WO 2007138335 A1; 12/06/2007). The device contains a bag with a portion of the brewed raw materials, placed on the plate. The plate may contain two wings and a grip in the central part. The sachet is connected to the central grip in such a way that the sachet is pulled into the interstore space.

This design does not allow to ensure the completeness and effectiveness of brewing, requires the use of auxiliary equipment for mixing sugar and does not solve the problem of extracting and disposing of a used bag without additional utensils.

A device for packaging tea brewing products is known (patent for the invention RU 2433940 C2; 11/20/2011). The package is made in the form of an inflexible water-permeable container, inside which a portion of the product is located. The container is made of a water-permeable flexible material spirally wound in the form of a tube of simple or complex shape in cross section with the fixation of the last turn. The package is a cylinder, and to ensure the mixing function, the generatrix of such a cylinder is greater than its radius.

The internal volume of the product container involved in brewing depends on the level of filling the bowl with liquid. The lower the liquid level, the more difficult it is to obtain a drink of satisfactory quality, and the use of opposed packaging of brewing products in a cup is difficult.

A feature that negatively affects the efficiency and completeness of brewing is that the structural rigidity is assigned to the packaging material, which reduces the number of holes for fluid circulation. This technical solution does not solve the problem of squeezing the liquid after brewing, which leads to the loss of the most valuable component during brewing products and uncontrolled runoff of the remaining liquid after removing the bag from the brewing tank.

Closest to the claimed invention is a device for brewing tea and squeezing a tea bag (patent US 5623865, 1997), which contains a hollow body and a device for retracting the tea bag with the brewed product inside the case to squeeze the bag and to prevent moisture from the bag on surrounding surfaces, such as a table. The retractor may be in the form of a rod with an external thread (US 5623865, Fig. 12A, Fig. 12B), while the tubular body is made with an internal thread identical in parameters to the external thread of the rod (US 5623865, Fig. 12A, Fig. 12B), the length of the threaded parts of the rod and the housing guarantees the movement of the retraction device relative to each other to contact the container with the brewed product with the inner surface of the conical section of the housing. The housing according to one embodiment of the invention has a conical section and a tubular section (see US 5623865, Fig. 28 and Fig. 29).

The disadvantages of this design include the fact that when using a flexible tea container (sachet), this invention does not allow squeezing the container (sachet) efficiently, as a result, the strength of the brewed tea is lower than it could be, and the remaining moisture in it gets on table linen (tablecloth, napkin) or human clothing, leaving tea stains on them.

Disclosure of invention

Despite the variety of approaches to the production of tea leaves for single (one-time) use, the design of a device for brewing tea has not been created, providing maximum comfort and ease of use.

The technical problems solved by this invention is the creation of tea leaves packaging, providing an increase in the degree of extraction of the extract from the brewed product, accelerating the brewing process, ensuring ease of use and simplifying the disposal of the used tea container (bag).

The solution to these technical problems lies in the fact that the device for brewing any product, in particular tea, coffee, herbs, contains a rigid case and a container with the brewed product, while the container is made in the form of a liquid-permeable bag, for example, from a filter paper or filter cloth, and a rigid case allows you to stir the brewed beverage, for example, by means of the case itself or by a spoon attached to the body or made integral with it. When stirring, the particles of the brewed product do not stagnate and do not accumulate in one place of the container, the liquid actively circulates in its cavity even at a low stirring speed, while ensuring the efficiency and uniform brewing of the entire contents. The case of the device for brewing a beverage is made with a conical section open from the base of the cone and with a hole from the side of the top, and the conical section of the body near the top passes into a tubular element with an internal thread, in the cavity of which a rod with a reciprocal external thread is located and has the ability to move however, at one end of the aforementioned threaded rod, a container (sachet) with a brewed product is fixed, and a holder can be made at the other end. The length of the threaded parts of the rod and the housing guarantees the stroke of the rod relative to the housing to enable the container (sachet) to interact with the brewed product with the inner surface of the conical section of the housing, while the length of the external thread of the rod cannot be less than 3 mm and the conical section of the housing with a diameter of less than 3 mm The interaction of the inner walls of the conical section of the housing and the container leads to compression of the container and the release of liquid.

The difference of the present invention is that to accelerate and improve the extraction (extraction process) of the container with the brewed product, a flexible container (sachet) with the brewed product is used, while the inner surface of the conical section of the body can be provided with a screw-shaped protrusion or at least one protrusion located along the generatrix of the conical section of the housing or at an angle to it. Additionally, the conical portion of the housing may have a friction surface that provides friction with relief or material. The protrusions provide for the container to twist during the rotational movement of the rod, since the extraction of the contents of the container occurs due to the sum of two factors - due to the translational movement of the container and pressing it to the inner conical surface of the body and due to the twisting of the container due to the rotational movement of the rod, which is due to friction at the contact point of the inner protrusions (or protrusions) of the conical surface of the rigid body (screw-shaped or any other shape).

The movement of the rod along the thread (both translational and rotational) allows more complete removal of the liquid from the contents of the container (sachet) with the brewed product, and ensures the regulation of the degree of extraction of the brewed product to a degree that excludes the transfer of liquid outside the container with the resulting beverage.

The shape of the holder, located at the end of the rod, can be any convenient to hold, for example, cylindrical, or flat rectangular, or square, or triangular, etc., and the outer surface of the holder can be either smooth or grooved.

The case of the device for brewing a drink may contain a spoon located on the side of the conical section and rigidly connected with it. In another embodiment, the spoon attached to the conical portion of the housing may have a telescopic structure.

The present invention achieves the technical effects of controlling the extraction of brewed products due to the presence of threads on the body and the rod in combination with the conical portion of the body open from the base of the cone, which simplifies the extraction of the contents of the container with the brewed product and ensures complete extraction of soluble substances by mixing and a more complete extraction of the brewed product, and also simplifies the local disposal of the used device.

The end of the process of preparation of the drink is carried out by squeezing the container with the brewed product, while due to the design of the device body the risk of dropping drops of liquid remaining in the container outside the brewing tank is eliminated, which ensures ease of brewing and completeness of extraction. The extraction of the container (sachet) with the brewed product is ensured by the use of a flexible container (sachet) with the brewed product in combination with a rigid body having a hollow conical section with a hole in the apex. Near the apex, the conical section of the body passes into a tubular element covering a hole in the apex of the cone, while the tubular element is made with an internal thread, inside of which there is a threaded rod with an external thread that can move along the internal thread of the tubular element. The fastening of a flexible container (sachet) with the brewed product to the end of the threaded rod, which allows moving the container into the cavity of the conical section of the body when moving relative to the body, can be carried out by means of an integral and detachable connection, for example, via a clamp, and is suitable for containers containing at least one chamber known shapes such as prism, pyramid, cone, sphere, etc. The body of the device is made by known methods, for example by injection molding, extrusion, etc., from materials approved for contact with food products, such as metals or polymers.

The implementation of the invention

A flexible container 1 with a brewed product made of a permeable material (filter paper, fabric, porous flexible material, perforated flexible material, etc.) by means of a known one-piece or detachable connection 2, for example through a clip, is fixed to the end of a rigid threaded rod 3, which is a device for drawing the container 1 into the device body. In the brewing process, the container 1 with the brewed product is placed in a brewing tank 7 filled with liquid 10, preferably water.

The housing is made up of a tubular element 4 made in one piece with an internal thread designed to interact with the threaded rod 3 and the cone section 8. The cone section 8 is open from the base of the cone and is made with a hole at the apex, while the conical section passes into a cylindrical tubular element 4 with internal thread, in which the threaded rod 3 is installed. The tubular element 4 is located coaxially with the hole at the top of the conical portion of the housing, which allows the movement of the threaded rod 3 along the tube that element 4 with the ability to exit towards the conical section 8.

On the inner surface of the conical section 8, protrusions are formed, made, for example, along a helical line (in a spiral) or in the form of separate rectilinear elements located along the generatrix of the cone or at some angle to it.

Additionally, the inner surface of the conical section of the housing may have a friction surface that provides adhesion (increased friction) due to the material or relief with the container (bag), which ensures intensive twisting of the container with the brewed product while it is pressed against the inner surface of the conical section 8 during the thread rod 3 up. This ensures the regulation of the degree of extraction of the brewed product and the elimination of the transfer of liquid outside the container with the resulting beverage when the container is pressed.

A device for drawing the container into the device body, namely the threaded rod 3, passes through the tubular element 4 of the body and ends on the outside with the holder 6. On the inside, i.e. from the side of the conical section 8, a container with the brewed product is attached to the threaded rod. The holder 6 is made in one piece with the threaded rod 3 and allows the threaded rod to rotate and progressively move due to the presence of a screw pair of a threaded rod - a tubular element with an internal thread.

The device operates as follows.

In the container for brewing 7, filled with liquid 10, place the container 1 with the brewed product. Together with the container 1, the conical section 8 of the device body can be immersed in the liquid 10. During the brewing process, the consumer stirs the prepared beverage by holding the threaded rod 3 by the holder 6 or by holding the device case by the tubular element 4 of the device body, which are located above the liquid 10 located in the brewing tank 7. These actions intensify the circulation of the liquid 10 through the liquid permeable the material of the container 1 with the brewed product and provide increased speed and completeness of brewing. At the end of the preparation of the beverage, the container 1 is removed by the consumer from the brewing tank 7 and is located above it. The user begins to rotate the threaded rod 3, acting on the holder 6 and while holding the device casing with the other hand by the tubular element 4 of the housing. These actions lead to the interaction of the external thread of the threaded rod 3 and the internal thread of the tubular element 4 of the housing.

The extraction of the liquid stored by the brewed product in the container 1 is ensured by retracting the flexible container 1 into the conical section 8 of the device body by rotating the holder 6 integrally with the threaded rod, while the rectilinear and rotational movement of the flexible container 1 fixed simultaneously on a threaded rod 3 moving along the thread along the tubular element 4 of the housing. Due to the rectilinear motion, the container 1 is pressed against the inner surface of the conical section 8, giving up the residual liquid remaining in it. At the same time, the container 1, rotating together with the threaded rod, encounters an obstacle - a protrusion or protrusions on the inner surface of the conical section 8 (or interacts with the frictional inner surface of the conical section of the body), is intensively twisted, due to which the residual liquid contained in the brewed product is completely wrung out and drains into the container 7 for brewing.

The inner surface of the conical section of the housing, additionally having a friction surface, provides friction with a relief or material and allows you to adjust the degree of extraction of the brewed product and eliminates the transfer of fluid outside the container with the resulting beverage during the spin cycle.

After the extraction is completed, the device for brewing a drink, mainly tea, due to the absence of moisture and the parts of the container 1 protruding beyond the device, can be safely placed in the immediate vicinity of the brewing tank 7, for example, on the surface of the table, where it arrives until will be sent to the place of collection or disposal.
