Field of technology to which the invention relates.

The group of inventions relates to lids with drinking holes for use with disposable frustoconical-shaped cups, having an outer profiled circular contour made capable of being attached to the upper edge of the disposable cup, the outer profiled circular contour being connected to a protruding circular contour, having an opening for drinking.

The prior art of the first embodiment of the invention.

A lid with a drinking hole for a disposable cup having a truncated cone shape, having an outer profiled circular contour made to attach to the upper edge of the disposable cup, the outer profiled circular contour being connected to a protruding circular contour having a drinking hole, within the protruding circular contour an obturation is arranged, is known from the prior art, described for example in patent for invention No. 60835, published in 2006.
This device is the closest in technical essence to the claimed invention and is taken as a prototype to the proposed invention. The disadvantage of this device is the inconvenience of using a glass closed with the proposed lid. Including - impossibility of dense stacking of disposable glasses with hot and cold drinks when using the proposed lids on them. That is, this lid although is intended for use with a disposable cup, but with its help it is not possible to achieve the possibility of stacking the said disposable cups with hot and cold drinks by placing one cup on top of the lid of another cup.

Disclosure of the first embodiment of the invention.

Relying on this original observation, the present invention is primarily intended to provide a lid with a drinking hole for a disposable cup having a truncated cone shape, having an outer profiled circular contour made capable of being attached to the upper edge of the disposable cup, the outer profiled circular contour being connected to a protruding circular contour having a drinking hole, an obturation being arranged within the protruding circular contour, allowing at least one of the at least one of the
To achieve this goal, the recess is made circular, with a radius corresponding to the radius of the lower contour of the disposable cup stacked on top, the recess walls are made at an angle, made with the possibility of tight contact with the walls of the lower part of the disposable cup stacked on top, and the recess has an annular groove, made with the possibility of accommodating the lower edge of the disposable cup stacked on top, and the protruding circular contour is made with the possibility of deflection and creating radial pressure.
Thanks to this advantageous characteristic, it is possible to tightly stack disposable cups with hot and cold beverages when the proposed lids are used thereon. This is ensured by three said features at once.

Indeed, the shirring is made circular, with a radius corresponding to the radius of the lower contour of the disposable cup stacked from above, so that the lower edge of the disposable cup is precisely inserted into the shirring.
Further, since the recess walls are made at an angle made to be in close contact with the walls of the lower portion of the disposable cup stacked on top, there is a close contact between the outer surface of the wall of the disposable cup and the inner surface of the recess wall.
And since the protruding circular contour is made with the possibility of deflection and creation of radial pressure on the disposable cup with liquid stacked from above under the action of gravity, it is this factor that holds the whole structure, i.e. tightly fixes each cup with the lid located at the bottom.

There is a possible variant of the invention in which the height of the walls of the beaker is in the range of 0.1-0.2 of the diameter of the beaker, which is caused by the design of the bottom of the beaker, at the height of 0.1 of the diameter of the beaker from the bottom end there is the bottom proper, it is less deformed in this place, and at the height of 0.2 of the diameter of the beaker from the bottom end there begins the shell if it is used according to the generally accepted standard.
Thanks to this favorable feature, it is possible to specify the exact ratio of dimensions, in which a reliable stacking occurs, but not much material is wasted on the production of the lid. If the ratio of the wall height to diameter of the lid decreases below 0,1, stacking is no longer effective. And at increase of the parameter of the ratio of the height of the recess walls to the recess diameter more than 0,2 - a lot of material is wasted for the production of the lid, plus the recess is lowered into the useful volume of the glass and does not allow it to be filled to the required level.
There is a possible embodiment of the invention in which the recess has a groove in its center, the sum of the recess depth and the groove depth being in the range of 80-90% of the total height of the lid.
Due to this advantageous feature, it becomes possible to increase the convenience of drinking from a glass closed with the proposed lid. This is provided by the said features. Indeed, due to the fact that the sum of the recess depth and the groove depth corresponds to the average length of the nose above the lip, it gives the convenience of placing the nose in the center of the glass closed with the proposed lid. In addition, the recess depth corresponds to the average length of the lips extended to comfortably drink and catch side spills.
There is a possible embodiment of the invention in which the groove is in the form of a ball segment.
With this advantageous feature, it becomes possible to manufacture a precise type of groove that is most technologically advanced and convenient to use.
There is a possible embodiment of the invention in which the lid has a closure valve arranged on the lid, wherein the closure valve has a resilient holder, one end of which is fixed on the side of the lid opposite the drinking hole, and the other end is connected to the valve, which has two stationary positions: an "open" position in which the holder is straight and the valve is located on the side of the lid on the left side of the drinking hole, and a "closed" position in which the holder is curved and the valve is located inside the drinking hole
With this advantageous characteristic, there is an opportunity to improve the convenience of drinking from a cup closed with the proposed lid. This is provided by the said features. Indeed, the presented solution does not have the disadvantages of the prototype. The valve is located on the left side of the drinking hole, considering that 95% of people are right-handed, such an arrangement makes such a solution really convenient. After use, the valve, even if it is not seated on the parking space, returns to its original position, due to the elasticity of the holder on which it is held.
There is a possible embodiment of the invention in which the cover has a parking protrusion for the valve arranged on a protruding circular contour, the valve having a third stationary position when it is fixed on the parking protrusion.
Due to this advantageous characteristic, it is possible to further increase the convenience of drinking from a glass closed with the proposed lid by providing a parking space arranged in such a way that the process of parking, after use, can be performed with a single thumb without any additional manipulation.

Implementation of the first embodiment of the invention.

A lid having a drinking hole for a disposable cup is used as follows.
Step 11. The lid with a drinking opening for a disposable cup is tightly fixed to the upper portion 21 of the disposable cup, as it has an externally profiled circular contour 11 made to be fixed to the upper edge 21 of the disposable cup.
Step 12: On said lid, another disposable cup containing liquid 3 can now be positioned and tightly secured. Since the walls of the shirring 141 are angled, it becomes possible for the lid to touch tightly the walls 22 of the lower portion 22 of the disposable cup stacked on top. Since the obturation has an annular recess 142, the bottom edge 22 of the disposable cup stacked from above is accurately placed therein. And since the protruding circular contour is made with the possibility of deflection, its deflection creates radial pressure on the disposable cup with liquid 3 stacked from above under the influence of gravity.
Step 13. When the liquid is consumed, the beaker 2 is lifted as shown in figure 5 and the nose of the user falls precisely into the recess 15.
Stage 14. In the transport position, the valve 16 is inside the drinking opening 13.
Stage 15. When the liquid is consumed, the valve 16 is outside the parking protrusion 18, the beaker 2 is raised. The valve 16 does not interfere with drinking. Even if it is not seated in the parking space, it returns to its original position, due to the resilience of the holder 17 on which it is held.

Implementation of the second embodiment of the invention.

Step 21. The lid 1 having a drinking opening for the disposable cup is tightly fixed to the top portion 21 of the disposable cup, as it has an externally profiled circular contour 11 made to be fixed to the top edge 21 of the disposable cup.
Step 22. When liquid is consumed, the tumbler 2 is lifted as shown in figure 5 and the nose of the user falls precisely into the recess 15.
Step 23. Another disposable cup containing liquid 3 can now be placed on said lid and tightly fixed. Since the walls of the shroud 141 are angled, it is possible for the lid to touch tightly the walls 22 of the lower part of the disposable cup stacked on top. Since the obturation has an annular recess 142, the bottom edge 22 of the disposable cup stacked from above is accurately placed therein. And since the protruding circular contour is made with the possibility of deflection, its deflection creates radial pressure on the disposable cup with liquid 3 stackable from above under the influence of gravity.
Step 24. In the transport position, the valve 16 is located inside the drinking hole 13.
Stage 25. When the liquid is consumed, the valve is outside the parking protrusion 18 and the beaker 2 is lifted. The valve 16 does not interfere with drinking. Even if it is not seated on the parking protrusion, it returns to its original position, due to the resilience of the holder 17 on which it is held.

Implementation of the third embodiment of the invention.

Step 31. The lid 1 having a drinking hole and a valve for the disposable cup is tightly fixed to the top of the disposable cup 2, as it has an externally profiled circular contour 11 made to be fixed to the upper edge 21 of the disposable cup.
Step 32. In the transport position, the valve 16 is located inside the drinking opening 13.
Stage 33. When the liquid is consumed, the valve 16 is outside the parking protrusion 18, the tumbler 2 is raised. The valve 16 does not interfere with drinking. Even if it is not seated on the parking protrusion, it returns to its original position, due to the resilience of the holder 17 on which it is held.
Stage 34. When liquid is consumed, the glass 2 is raised as shown in FIG. 5, and the user's nose falls precisely into the recess 15.
Stage 35. Another disposable cup containing liquid 3 can now be positioned on said lid and tightly secured. Since the walls of the shroud 141 are angled, it becomes possible for the lid to touch tightly the walls 22 of the lower portion of the disposable cup stacked on top. Since the obturation has an annular recess 142, the bottom edge 22 of the disposable cup stacked from above is accurately placed therein. And since the protruding circular contour is made with the possibility of deflection, its deflection creates radial pressure on the disposable cup with liquid 3 stacked from above under the influence of gravity.

Industrial applicability.

The lid with a drinking hole for a disposable cup can be carried out by a person skilled in practice and, when carried out, ensures the realization of the claimed purpose. The possibility of implementation by a skilled person in practice follows from the fact that for each feature included in the utility model claim on the basis of the description, the material equivalent is known, which allows us to conclude that it meets the criterion of "industrial applicability" for the utility model, as well as the criterion of "completeness of disclosure" for the utility model.
In accordance with the proposed invention, the applicant manufactured a prototype of a lid with a drinking hole, for a disposable cup, which passed all tests and was approved by customers. Series production has been started.
Experimental operation of such a device showed that the lid is securely fixed on the disposable glass, that when stacking, after fixing the upper glass with liquid, the lid fits more tightly around the lower, locked glass due to deformation inward. Up to five glasses can be stacked, which in itself is excessive. Very comfortable to drink, due to the protruding circular contour, drinking becomes anatomically comfortable. The nose does not touch the bottom of the glass, even with the most extreme tilt of the glass, and drinking is indistinguishable from drinking from a normal cup or glass that is not closed. The valve of the product, located on the left side, does not get in the way when it is not used and is well "parked" after use on a specially provided for this purpose ledge.
Thus, due to the fact that the recess is made circular, with a radius corresponding to the radius of the lower contour of the disposable cup stacked from above, the recess walls are made at an angle, made with the possibility of tight contact with the walls of the lower part of the disposable cup stacked from above, and the recess has a circular groove, made with the possibility of placing the lower edge of the disposable cup stacked from above, and the protruding circular contour is made with the possibility of bending and creation of a radial pressure on the stacked from above disposable cup with a liquid under the action of gravity, and the stated technical result is achieved, namely: the possibility of tightly stacking disposable cups with hot and cold beverages when using the proposed lids on them.
An additional technical result achieved by the proposed invention is that due to the protruding circular contour drinking becomes anatomically comfortable. The nose does not touch the bottom of the cup even at the most extreme inclination of the cup, the drinking process is indistinguishable from drinking from an ordinary cup or glass that is not closed. The valve of the article can be located on the left side and does not get in the way when it is not used, and is also well "parked" after use on the protrusion 18 specially provided for this purpose.
