Description

TECHNICAL FIELD OF THE INVENTION

Disposable straw cup lids are widely used in retail outlets for takeaway hot drinks.

LEVEL OF TECHNOLOGY

Known analogue - a lid for a disposable cup with a tube (US patent No. US 6142335, 06.01.1999). Containing a part for attaching and fixing the lid to the cup and a tube built into the lid, which contains a cylinder-shaped part located above the lid, adapted for the mouth, and a part located under the lid capable of being placed in a cup, having a semicircular cross-section.

The disadvantage of the analogue is the impossibility of using a lid with cups having different dimensions, since to ensure the functioning of a tube with a semicircular cross-section, a tight fit of the tube to the wall of the cup is necessary. And if the size of the cup differs from that for which the tube is designed, a gap will inevitably appear.

Also known is the lid of a disposable cup nestable (US patent No. US 4811860, 03/14/1989), adopted as a prototype. Containing a part for attaching and fixing the lid to the cup and a tube built into the lid, which contains a part located above the lid, which has a smaller length, the shape and size of which is made to ensure the convenience of grip by the mouth, and a part located under the lid, which has a large length, closed cross-section and made with the possibility of placement along the height of the cup. The surface of the lower side of the lid has a shape that repeats the surface of the upper side of the lid and both surfaces have the necessary slopes, made with the possibility of inserting the lid into another similar lid with contact between the upper surface of one lid and the lower surface of the other with minimal gaps.

The disadvantage of the prototype is the low throughput of the tube, due to the need to make the lower hole of the tube is much smaller than the upper hole to ensure the possibility of installing the cover on another of the same cover with minimal gaps.

An analogue is also known - a lid with a tube for a disposable cup, containing a part for attaching and fixing the lid to the cup and a tube built into the lid, which contains a part located above the lid having a shorter length, the shape and size of which is made to ensure the convenience of gripping by the mouth. And a part located under the lid, which has a large length, a closed cross-section and is made with the possibility of being placed along the height of the cup. The surface of the lower side of the lid has a shape that repeats the surface of the upper side of the lid and both surfaces have the necessary slopes, made with the possibility of inserting the lid into another of the same lid with contact of the upper surface of one lid of the lower surface of the other with minimal gaps. This is achieved by the fact that the shape of the lower part of the tube has folds located along the tube on its opposite sides, each of which is formed by two faces. Outside with respect to the volume of the tube, the angle between which in the cross section of the tube is less than 180 degrees, and the folds are made with the possibility of changing the angle described above to an angle of more than 180 degrees.

The disadvantages of the known technical solution include the violation of the sterility of the lid during complex and repeated manipulations with the lid, which requires the participation of two hands and the possible touching of the tube with dirty hands, which is especially dangerous in viral epidemics and pandemics.

DISCLOSURE OF THE INVENTION

This technical solution is aimed at increasing the convenience and efficiency of jumping out of the container (glass) when drinking drinks, without touching the tube with your hands, as well as maintaining the sterility of the lid elements when drinks enter the mouth of the consumer.

The technical result is achieved in that the cover with a tube for a disposable cup contains a part for attaching and fixing the cover to the cup and a tube built into the cover, which contains parts located above and below the cover. The tube built into the lid is connected to the lid by a compressed corrugated cone-shaped cavity, and has a protective plate with a loop, hermetically placed on the lid. And the inner cavity of the tube, located under the lid, is made in the form of a row of cylindrical cavities inserted into one another, with the possibility of telescopic extension and placement in height above the cup, when the protective plate is removed from the surface of the upper lid. In this case, the rise of the tube after removing the protective plate on the lid is carried out under the action of a compressed corrugated cone-shaped cavity, the edges of the folds straightening when removing the protective plate and under the action of warm air or gas of soft drinks providing telescopic extension of the cylindrical cavities inserted into one another and automatically increasing the dimensions of the tube by more than 150% of the original.

FIG. 1 shows a general view of a cup with a lid, where

1 - disposable cup

2 - lid with built-in tube

3 - protective hinged cover

FIG. 2 shows a cross-section of a lid with a tube for a disposable cup in the initial position, where

4 - corrugated conical cavity

5 - outer cylindrical cavity of the telescopic tube

6 - inner cylindrical cavity of the telescopic tube

7 - sealed valve with a loop

8 - fixing layer that allows the lid to be hermetically “soldered” to the glass after filling it with contents.

FIG. 3 shows a cross-section of a lid with a tube for a disposable cup in the position ready to drink beverages (the protective film is removed), where p. 1-8 correspond to the above points in FIGS. 1 and FIG. 2.

CARRYING OUT THE INVENTION

The essence of the proposed technical solution lies in the fact that after filling the disposable cup 1 with liquid in sterile factory conditions, the cover 2, with a telescopic tube built into the corrugated conical cavity 4, is put on and hermetically fixed on the cup 1 using the fixing layer 8. Moreover, it is intended for the mouth. the inner cylindrical cavity of the telescopic tube is sealed with a sealed valve with a loop 7. And the corrugated cone-shaped cavity 4 with an inserted telescopic tube (5, 6) is tightly closed, fixed on the cover 2 by a protective hinged cover 3, hermetically protecting the corrugated conical cavity, with an integrated telescopic tube folded condition. Then each cup is sealed in a protective film for further transportation and storage.

To consume liquid from the above-described cup (FIG. 3), the protective film is torn and the protective flip cover 3 is opened. Then the disposable cup 1 is shaken. As a result, under the influence of gases / released heat, the corrugated cone-shaped cavity 4 is compressed, pushing the cylindrical cavities 6 and 5 nested into each other, which makes the telescopic tube unfold and rise above the surface of the lid 2 of the disposable cup 1. Moreover, the protective flip cover 3, leaning on the lower cylindrical cavity 6 provides the telescopic tube with an additional stiffener. At the final stage, pulling the loop of the sealed valve 7, we tear off the valve from the cylindrical cavity 5, and, immersing the cylindrical cavity 5 in the mouth, we absorb the liquid from the glass, avoiding contact with a hostile environment at all stages of bringing the telescopic tube from the glass into working condition.

The technical result of the invention is achieved due to the fact that the tube is connected to the cover by a compressed corrugated cone-shaped cavity and has a protective plate with a loop, hermetically placed on the cover. And the inner cavity of the tube itself is made in the form of a row of cylindrical cavities inserted into one another, having a closed cross-section, made with the possibility of telescopic extension in height above the cup, when the protective plate is removed from the surface of the upper cover. In this case, the rise of the tube above the lid after removing the protective plate on the lid is carried out under the action of a compressed corrugated cone-shaped cavity, the edges of the folds straightening when removing the protective plate. And under the influence of warm air or gas of soft drinks, which provides a telescopic extension of cylindrical cavities inserted into one another, which increases the dimensions of the tube by more than 150% of the original.

Thus, when using the proposed technical solution, the following are provided:

- increasing the convenience and efficiency of jumping out of the tube from the container (glass)

- drinking drinks without touching the straw with your hands,

- observance of the sterility of the lid elements entering the mouth of the drink consumer.

- maintaining the sterility of containers in road and domestic conditions, as well as in a pandemic.

An invention characterized by the above set of essential features is not known in the Russian Federation or abroad as of the filing date of the application and meets the requirements of the “novelty” criterion.

The invention can be implemented in an industrial way using known technical means and meets the requirements of the criterion "industrial applicability".
