Description

The invention relates to the field of catering for the preparation of hot drinks in the home, organizations, fast food outlets, offices. Methods for making disposable containers, or parts thereof, from various materials are widely known and are made using molding techniques.

For example, it is known to manufacture tops for packaging containers by injection molding, which gives a high degree of precision and quality, but makes it difficult or impossible to manufacture tops containing a gas-tight layer, which is desirable in fruit juice packaging, for example. Another well-known technique is the conventional molding of sheet thermoplastics from a sheet of heated material, which may itself include a barrier layer. However, this method gives undesirable non-uniform material thickness and less accuracy for different parts.

Convention priority: 29.01.1997 SE 97 00 259-6, Published: 20.04.2003 Bull. No. 11, Method for manufacturing a packaging vessel for liquid contents. Patent holder(s): TETRA LAVAL HOLDINGS AND FINANCE SA (SN)

In the manufacture of the aforementioned packaging vessel by the method of the present invention, the various parts of the packaging vessel are manufactured separately, after which they are combined with each other in an appropriate manner.

The method has the disadvantage that it is relatively slow both when extruding the required length of sleeve to make a packaging vessel, and when cooling a packaging vessel made from this sleeve, since this packaging vessel must remain in the halves of the mold until until its temperature drops so much that the material acquires the ability to maintain geometric dimensions, in addition, this method does not solve the problem of wide use, including for brewing tea or other hot drinks directly using tea leaves in this vessel.

Also known is a disposable cup with a substance inside, packed in a package impervious to liquid and oxygen in the form of a foot. No. 9. (45) Published: 29.08.2019 Bull. No. 25.

The method relates to inserting a capsule with a substance into a disposable cup for preparing a drink, in which the capsule is filled with the substance to the brim, while the edge of the round opening of the capsule remains uncovered with the substance and the capsule is held with the round opening upwards, then the disposable cup is lowered to the capsule until the bottom of the cup will not be pressed against the side of the capsule, thus forming a closed volume for storing the substance in it. In this case, the orientation of the cup is such that its round hole is located at the bottom. The inner diameter of the cup at the bottom is equal to the outer diameter of the rim of the capsule, and the diameter of the cup at its rim is greater than the inner diameter of the cup at the bottom.

This method can find a consumer as a way to exclude the effect of oxygen and moisture on the substance inside the capsule, however, during the packaging process, after the substance has been placed in the capsule, it is necessary to make a recess of the capsule and stick it to the protrusion in the cup, in addition, since the shell is made with the ability to pass liquid, it does not prevent the penetration of oxygen and moisture, which can adversely affect the freshness of the substance stored in the disposable cup.

A known method of manufacturing a disposable cup for hot and chilled drinks RU 2016133134, publication date of the application: 14.02.2018 Bull. No. 5., according to which the glass is made mainly in the form of a truncated cone closed with a bottom, in which the upper diameter is larger than the lower one, while the blank for the side wall of the glass is made of cardboard, which is pre-laminated on at least one side and then attached to it on the other hand, a non-woven material, after the manufacture of the workpiece, the side wall of the glass is formed from it, while the laminated side of the workpiece is placed inside the glass, then the edges of the workpiece forming the side wall of the glass are fastened together with a longitudinal seam, in addition, the workpiece of the bottom of the glass is made from laminated at least on one side of the cardboard, place the bottom at the bottom inside the side wall of the glass with the laminated side to the top and then fasten it to the bottom of the side wall of the glass. This method was chosen as a prototype.

The known method has a limited application, i.e. it can only be used for hot and chilled drinks that are already ready and does not involve the use of a disposable glass for brewing the contents.

The technical task of the present invention is to implement a method for manufacturing a disposable cup, which makes it possible to manufacture a disposable cup with a part by subsequently combining this part into a finished, liquid-tight container for hot drinks with the possibility of brewing the contents in the same glass, as well as the expedient use of material for making partitions.

This technical problem is solved by a method for manufacturing a disposable cup for hot drinks, according to which the cup is made in the form of a container with a closed bottom in the form of a truncated cone, in which the upper diameter is larger than the lower one, while the walls of the cup are made of cardboard laminated with at least on the one hand, according to the invention, an internal partition is made, for this, the cardboard laminated on at least one side is bent in the shape of a container in the form of a truncated cone, the connecting seam is soldered to ensure that the edges of the seam are impermeable to liquid, the resulting cardboard bent in the shape of the container is connected to the bottom of the partition , made of cardboard laminated on at least one side, the bottom of the partition is subjected to stamping with the formation of perforation over the entire area of the bottom of the partition, and an internal partition is obtained with edge parts above and below the bottom of the partition, the partition is fixed inside the glass until it fully adheres to its walls, forming a closed volume of the container for brewing the contents.

A disposable cup designed specifically for hot drinks is made from several parts - a body and an internal partition, each of which corresponds to this purpose in the light of the choice of material and manufacturing method.

The proposed method of manufacturing a disposable cup for hot drinks differs from the known ones in that additionally a perforated partition is made separately from cardboard laminated on at least one side by bending in the shape of a container in the form of a truncated cone, the inner partition 3 is stamped to form a perforation 4 of the entire area and get an internal partition with edge parts on top 5 and below 6 from below from the bottom of the partition 3, fix it inside the glass until it fully adheres to its walls, forming a closed volume of the container for brewing the contents.

The currently available solutions described in the previously cited publications do not meet this need.

The technical result when using the invention is to reduce the time of preparation of the drink, as well as to increase the consumer properties of the container, which consists in the manufacture of the container itself by combining a disposable container and tea leaves as a whole, as well as the use of an intermediate partition for preparing a drink, depending on the desire of the consumer that do not require special methods of fixing it.

The method for manufacturing a disposable hot drink cup according to the present invention is given by reference to the accompanying drawing, which is schematic and shows only the details necessary to understand the present invention.

On the attached drawing:

fig. 1 general view of the glass in section; fig. 2 top view of the internal partition; Where: 1 - disposable container; 2 - bottom of the container; 3 - internal partition; 4 - perforation; 5 - upper edge of the partition; 6 - lower edge of the partition.

The method is implemented as follows:

In a disposable glass 1, leaf tea or any other product of plant origin (coffee, herbs, berries) is poured onto the bottom 2. An internal partition 3 is inserted, pre-made in the shape of a container in the form of a truncated cone, with the formation of a perforation 4 of the entire area of the bottom of the partition, and the partition is fixed inside the glass 1 until it fits snugly against its walls, forming a closed volume of the container for brewing the contents. The total height of the perforated inner partition can be 18-30 mm, which is sufficient to accommodate the contents to be brewed. The perforation of the septum is 2.5-5.0 mm, allowing the rapid penetration of hot water to brew the contents and obtain the necessary drink. The presence of edges 5 and 6 of the inner partition 3 according to the shape of the container in the form of a truncated cone ensures its tight fit to the inner walls of the glass and does not require special methods of its fixing. Making the inner partition of cardboard, which is pre-laminated using food lamination, is suitable for the use of brewing the contents and is harmless to the consumer. In addition, laminated cardboard does not allow containers to be deformed under the influence of hot water, unlike analogues where filter materials are used as additional devices.

To prepare a drink, you need to pour a certain amount of hot water, and it is ready after a short period of time (1-10 minutes). For convenience and speeding up the brewing of the contents, the container can be closed with a lid.

To expand the functionality, you can use the internal partition and, on your own, to brew any kind of tea or drink at the request of the consumer.

Since the operations of manufacturing a disposable cup, i.e. the formation of the inner wall, as well as the stamping operation, can take place at relatively high speeds, it is possible to rationally and economically use the method in accordance with the present invention for the manufacture of a disposable cup.
