Description

The utility model relates to the field of the food industry, in particular, to means for preparing drinks, namely, disposable drip-type filter devices designed for the quick preparation of hot drinks using ground and / or grain coffee, tea, herbs, etc. , and can be used at home, in the workplace, while traveling and in public catering.

As a method of making coffee, the drip method of filtering ground coffee filled with hot water through paper has been widely used for a long time, making it possible to enjoy real coffee prepared in a simple way. This method, as a rule, allows extraction to obtain several cups of coffee at the same time.

At present, instead of the conventional paper drip filtering method, which is mainly for extracting several cups of coffee, there are disposable drip type filter bags on the market that are designed to extract one cup of coffee, tea, etc. in a simple way.

Various containers made of liquid-permeable material are known, for example filter bags which are opened and filled with the product by the beverage consumers themselves, as well as closed filter bags which are filled industrially with the drink product.

Due to the fact that filling the filter bags with the brewed product by the user himself leads to significant inconveniences associated with the need to fill in a certain amount of product, the possibility of spilling the brewed product on surrounding objects, clothing during filling with the product or when disposing of the used filter bag, the most widespread application was received by filter bags filled with the product in an industrial way.

The main technological requirements for such means for preparing hot drinks are: ensuring maximum comfort (convenience), safety and hygiene in the process of preparing drinks, expressed in the protection of human fingers from exposure to the hot liquid in which the drink is brewed, and preventing contact of human fingers with container with the brewed product.

These requirements are least met by both closed and open filter bags, which do not have additional special means with which it would be possible to carry out all technological steps for preparing the brewed product, including removing the filter bag from the vessel with squeezing the residual liquid from the brewed product. product. Under these conditions, it is necessary to squeeze out the residual liquid from the filter bag either with the fingers of a person, or with the help of a teaspoon and a thread that is attached to the bag or another element of the filter bag. Such technological actions reduce the level of comfort during the preparation of the brewed beverage and are likely to violate the hygiene requirements for the preparation of beverages.

Known filter for coffee, designed for individual preparation of liquid coffee, described in the patent for the invention of the Russian Federation No. 1414310, class. A47J 31/02, Appl. December 24, 1981, publ. 07/30/1988

The well-known coffee filter is a compact bag in a folded form, which contains a base plate with notches (fold lines) and an intermediate section, in the central part of which there is a hole for pouring hot water, a pair of support legs with slots that form gripping elements for installation on a cup (container) placed on opposite sides of the intermediate section, a bag of filter paper in the form of a flat sack with ground coffee placed in it, attached to the inner surface of the base plate, on the outside of which a round removable cover is installed that closes the hole for pouring hot water into filter. Available notches (fold lines) on the plate and on the support legs, allow you to install the filter on cups (containers) of various diameters.

The disadvantage of the known coffee filter is the complexity of the design, the inconvenience of using the filter due to the need to open it by removing the cover from the outer surface of the support plate, selecting the bending points of the support elements depending on the size of the cup (container) for preparing a drink, the presence of a hole in the central part of the support plates for pouring hot water into the filter and the possibility of pouring ground coffee out of this hole when manipulating the open filter, when preparing support elements for installing the filter on the container, the possibility of spilling wet ground coffee from the open filter hole onto objects near the brewing container, as well as soiling clothes when disposing of the coffee filter.

Known filter package for coffee, presented in US patent No. 4519911, class B01D 23/28, Appl. March 29, 1983, publ. 05/28/1985, containing a reusable support device in the form of a collar-shaped support element made of thick paper (thin cardboard), having many longitudinal folds that allow it to be flattened, with support legs at its lower end for installation on a cup, having the ability to transform and move outward from the support element, a filter attached to the inner surface of the support element. The bag of filter material with coffee powder is placed in the support device and then thrown away after use. For further reusable use of the supporting device, a supply of coffee bags is required.

The disadvantages of the known filter bag for coffee are as follows:

- inconvenience when using it, associated with the risk of thermal burns to the user's fingers when preparing a drink and disposing of a used bag of hot coffee powder. In addition, because coffee powder in a packaged bag is placed in a slide; when it is brewed, uniform moistening of the entire volume of ground coffee is not ensured, which is necessary to obtain a high-quality drink. First, the top layer of coffee powder in the bag is wetted, and the penetration of hot water into the pore space of the inner layers of coffee in the bag is somewhat difficult, which increases the coffee brewing time, or to speed up the brewing process, you will need to manually shake the wet hot bag with coffee being brewed, which is unsafe for the hands of the consumer;

- the possibility of violating hygienic requirements when handling the bag, because when removing the coffee bag from the packaging, as well as when placing it further into the supporting device (brewing container), the bag is allowed to come into contact with the hands of the person using the supporting device, as well as with foreign objects.

The closest in technical essence to the claimed, selected as a prototype, is the filter package presented in the description of the patent for the invention of the Russian Federation No. 2638508, class. A47J 31/06, Appl. December 11, 2013, publ. December 13, 2017

The well-known filter package contains a housing filled with an extractable substance, made in the form of an elongated flat rectangular package of a permeable filter sheet, and having an upper open end, supporting elements made of thin plate material located on the outer surfaces of two opposite front sides of the filter package housing , each supporting element has an upper part permanently attached to the body, made in the form of the letter "P", located along the upper end of the body and its sides, the central part located under the upper part in the center of the front side of the body in the direction of its width and permanently connected its lower part with the body, and the gripping part permanently connected to the upper part of the central part of the supporting element, made with the possibility of pulling it away from the body, while on the upper part of the supporting element along the upper part of the housing and on its gripping part are made symmetrically with respect to the vertical axis symmetry of the reference element at a distance from each other of two or more pairs of fold lines. This design of the well-known filter package is simple, economical and convenient when installed on a cup, a large opening in the upper part of the body facilitates the process of pouring hot water into the filter package.

The disadvantage of the known filter package lies in the existing inconvenience in its use due to the need to open the filter package by tearing off the upper part of the package along the perforated line with the formation of an open hole for pouring hot water, the possibility of spilling dry ground coffee from this hole, as well as getting wet hot ground coffee after using the filter bag on objects near the brewing container, soiling hands, clothes when it is disposed of. At the same time, there is a high probability that drops of the drink will get on the clothes or furniture of consumers, and as a result, damage to property, as well as injury in the form of a thermal burn.

The task solved by this utility model is to increase the convenience when using the filter bag and its disposal after use.

The problem is solved by the fact that in a filter package containing a housing filled with an extractable substance, made in the form of an elongated flat rectangular package of a permeable filter sheet, and having an upper open end, support elements made of a thin lamellar material located on the outer surfaces of two opposite front sides of the filter package housing, each support element has an upper part integrally attached to the housing, made in the form of the letter "P", located along the upper end of the housing and its sides, the central part located under the upper part in the center of the front side of the housing in the direction of its width and permanently connected by its lower part to the body, and the gripping part permanently connected to the upper part of the central part of the support element, made with the possibility of pulling it away from the body, while, at the same time, on the upper part of the support element along the upper open end the filter bag body and on its gripping part are made symmetrically about the vertical axis of symmetry of the supporting element, two or more pairs of fold lines are spaced apart, ACCORDING TO THE UTILITY MODEL, the filter bag body is provided with an element that overlaps its upper opening part and is connected to it integrally made of a water-permeable filter sheet in the form of a funnel with a cone facing the bottom of the filter bag body.

The presence of an element of a permeable filter sheet that overlaps the upper part of the filter bag body and is permanently connected to it:

- prevents particles of the brewed product from spilling out of the filter bag during operation and disposal, which increases the convenience of its operation and ensures safety requirements for the process of preparing drinks, expressed in the protection of human fingers from exposure to hot liquid in which the drink is brewed, and hygiene by preventing contacts of human fingers with a container with a brewed product, as well as in preventing unwanted particles and foreign objects from entering the coffee bag;

- leads to the absence of the need to open the filter bag housing.

The execution of the element from a permeable filter sheet, covering the upper open part of the filter bag body in the form of a funnel with a cone facing the bottom of the filter bag body, helps to increase the stability of the filter bag on the cup during the preparation of the drink, because, despite its small weight, it is under the influence of the pressure of the hot water poured into it and the weight of the hot water poured into it, flowing down inside it, providing a lower location of the center of gravity of the filter bag, which effectively avoids the tipping (falling) of the filter bag from a cup of coffee. At the same time, it also allows, due to the spillage of hot water in a circular motion along the cone-shaped walls of the element (funnel), to ensure a slower uniform continuous spill of hot water on the coffee powder during the entire process, to maintain the same water level and temperature in the container with the product to be extracted, thereby preserving a uniform consistency of coffee weighing in the filter, which increases the degree of extraction of the extract from the brewed product, speeds up the brewing process and creates conditions for obtaining a quality drink.

Which together increases the ease of use.

The technical result is an increase in convenience when using the filter package and its subsequent disposal.

The inventive filter package is novel, differing from the prototype in the above essential features, such as:

- the presence in the body of the filter package of an element that overlaps its upper open part and is permanently connected to it;

- implementation of the element that overlaps the upper part of the filter package body in the form of a funnel with a cone facing the bottom of the filter package body, which together ensure the achievement of the desired result.

The inventive filter package can be used for quick preparation of hot drinks using ground and/or grain coffee, tea, herbs, etc., and can be used at home, at work, while traveling and in public catering. The utility model is illustrated by the drawings shown in:

- fig. 1 - Front view of the filter bag before opening. (The areas shaded by dots indicate the portions of the support member attached in the indicated areas to the outer surface of the housing by heat sealing or gluing).

- fig. 2 - General view of the filter bag in axonometric view after its opening and installation on the cup.

- fig. 3 - Top view of the filter bag installed on the cup. The inventive filter package is made as follows (Fig. 1-3).

The filter package contains a housing 1 filled with extractable substance 2, made of a permeable filter sheet, made in the form of an elongated flat rectangular package and an element 3 integrally connected to it, overlapping its (housing) upper opening part 4. Element 3 is made in the form of a cone-shaped funnel with with a solid bottom facing the bottom of the body 1 of the filter bag. Filling the filter bag with ground coffee or other extractable product is carried out industrially through the initially open side rectangular part of the housing, which is sealed after filling the bag with the product. On the outer surfaces of the two front sides of the body 1 of the filter package is placed on the support element 5. The support elements 5 of the housing 1 are formed by stamping a thin plate material, such as a paper plate or a plastic sheet. Each supporting element 5 has an upper part 6, a central part 7 and a gripping part 8. The upper part 6 of the supporting element 5 is made in the shape of the letter "P" and is permanently attached to the body 1 along its upper open end 4 and the sides 9. The central part 7 of the support element is located under its upper part 6 in the center of the front side of the housing 1 of the filter package and is permanently connected to it (the housing) by its lower part 10. The gripping part 8 of the supporting element 5 is permanently connected to the central part 7 in its upper part 11 and is made with the possibility of pulling it from the body 1 of the filter package. At the same time, on the upper part 6 of the supporting element 5 and on its gripping part 8, two or more pairs of fold lines 12 are made at a distance from each other symmetrically relative to its vertical axis, which, due to the bending of parts 6 and 8 of the supporting elements, open the upper part 4 of the filter housing. -package and its installation on cup 13 (container for brewing the product). The filter package is used as follows.

The filter bag is removed from the sealed package, where it was placed folded. The gripping parts 8 of the supporting elements 5 located on the front sides of the housing 1 are pulled in mutually opposite directions, which, due to the fold lines 12 on the upper parts 6 of the supporting elements 5, ensure the opening of the upper part 4 of the housing 1 of the filter bag. Then, additionally, the gripping parts 8 are also pulled, which, due to the fold lines 12 on them, provide the possibility of hanging (installing) the filter bag on the cup 13 (capacity for brewing the extracted product). Further, through the upper part 4 of the body 1, gradually, in a thin stream, in circular motions along the walls of the cone-shaped element 3, hot water is poured, thereby ensuring a slow, uniform, continuous flow of hot water onto the coffee powder during the brewing process. Gradually seeping through the element 3, hot water evenly covers the layer of coffee located in the lower part of the body 1, and then the drink extracted from the coffee drips through the lower part of the filter bag into the cup. You need to pour hot water rather slowly, then the coffee will give all its taste and aroma. After the end of the brewing process, the lower parts of the gripping elements 8 are lifted up, the extracted product is pressed against the walls of the body 1 of the filter bag, the remains of the hot extracted liquid are dripped into the cup and the gripping parts 8 of the filter bag are removed from the cup. The used filter bag is disposed of without touching the user's fingers to its hot part.

Thus, the inventive filter package due to the proposed design of the housing is permanently connected to the element that overlaps its upper part, the implementation of this element from a permeable filter sheet in the form of a funnel with a cone facing the bottom of the housing:

- prevents particles of the brewed product from spilling out of the filter bag during operation and disposal, which increases the convenience of its operation and ensures safety requirements for the process of preparing drinks, expressed in the protection of human fingers from exposure to hot liquid in which the drink is brewed, and hygiene, by preventing contact of human fingers with a container with a brewed product, as well as preventing unwanted particles and foreign objects from entering the coffee bag;

- leads to the absence of the need to open the filter bag housing.

Together, this makes it possible to increase the ease of use of the filter package and its subsequent disposal, which achieves the solution to the problem.

Compared with the prototype, the inventive filter package is more convenient to use.
