    The closest to the isoR to the technical essence is the vessel, which has an inwardly directed throat in the shape of a truncated cone, with its large base facing upwards; a pointed lower base and a lid, the inner part of which is located in the throat and has cylindrical sections arranged one below the other with a groove between them - for placing the pointed basis of the throat and a lip-shaped annular seal on the upper portion, which is used to the surface of the throat 1.
    The disadvantage of such a vessel is a possible leakage.
    The purpose of the invention is to improve the tightness.
    This is achieved by the fact that in the proposed vessel the groove is made on the outer side of the upper cylindrical portion, and the lip-shaped seal is located at the intersection of the upper boundary surface of the groove with the outer surface of the upper cylindrical portion.
    Lig.1 shows the Krymka before it is introduced into the vessel; in Fig. 2, the lid is placed in the neck of the vessel.
    The vessel has an inward mouth of 1 in the shape of a truncated cone, facing upward with a large base 2, ic pointed. Lower base 3,
    The lid contains the upper outer. part 4, lower inside

    For fixing the position of the cover in the mountain-. 1 small vessel. The inner part 5 of the key has cylindrical sections 8 and 9 located one below the other. On the outer side | 1, the upper cylindrical portion 8 has a groove 10, and at the intersection of the upper boundary surface of the groove 10 with the outer surface of the upper cylindrical portion 8 there is a lip-shaped annular seal 11. Under the cylindrical portion 9 there is a section 12 in the shape of a truncated cone. The cover part is located at the groove 10, performs both retaining and sealing functions. This is achieved by the fact that the cross section of the groove 10 is essentially the shape of a dovetail tail, the surface 13 is comparatively hard and inflexible, slightly inclined towards the bottom of the groove, and the lip-like ring seal. 11 has a triangular cross section (top. The thickness of the neck 1 increases from the upper base 2 to the lower base 3. The neck 1 ends in the lower part with a conical surface 14, which, when intersected with the surface 15 of the neck 1, forms a point with an intersection edge 16. When closing The inner part 5 of the lid is inserted into the neck 1. In this case, the edge 16 of the neck is placed in the groove 10, and the lip-shaped ring seal 11 is connected to the surface 15 of the neck 1 directly below the conical surface 14. In this case, the lip-like The o-ring 11 bends downward. When the lid is inserted into the neck 1 of the vessel, the surface of the section 12 in the Truncated Cone Form first comes in contact. Because the roofs, as well as the vessel, are made of relatively flexible material, the surface of section 12 may expand the opening of the vessel. At the same time, the inner part of the lid is slightly compressed, thus passing through the narrowest part of the neck 1 its lower base 3. During this stage of passage, the surface 15 of the neck does not come into contact with the cylindrical section 8 of the cover, nor with a lip-shaped ring seal 11, When the cover is inserted to its maximum position, flange 7 prevents its further advancement. In this position, the bottom surface 13 of the groove 10 is located below the conical surface 14 of the neck 1, which allows the neck 1 to take the original position . In addition, the inside of the lid also expands. The rib 16 will rest on the bottom surface 13 of the groove 10, and when the input device (not shown) is removed, the lid, due to the flexibility of Flange 7, returns up to the position when the lower conical surface -14 of the neck does not abut surface 13. During this upward movement, the ring-shaped ring seal 11 rests on the surface 15 of the neck 1, and due to friction the lip-shaped seal 11 bends downward, taking the position shown in FIG. 2, Thus, during the insertion of the lid, due to its shape, it communicate :; a field such that the lip-shaped lip seal 11 acquires an optimum shape to prevent leakage from the vessel. However, only the lip-shaped ring seal 11 is in tight contact with the neck 1 of the vessel. Consequently, the contents of the vessel can pass between the conical surface 14 of the neck 1 and the groove 10, which increases the seal from the inside of the vessel and thus increases the effect of the seal. The special shape of the bottom surface 13 of the groove 10 and the shape of the conical surface 14 of the neck 1 contribute to the fact that the internal pressure in the vessel, which could push the lid out of the vessel, only reduces the diameter of the lower base 3 of the neck 1 and increases the adhesion forces between the lip-shaped seal 11 and the surface 15 of the neck 1, the location of the lip-shaped annular seal 11 at the intersections of the upper boundary surface of the groove 10 with the outer surface of the upper cylindrical section 8 is very important This makes the lip seal 11 compliant, which ensures that it is correctly inserted into the groove when the flap is inserted into the neck of one vessel. The bottom surface 13 of the groove 10 is formed with a slight inclination inward of the groove 10, which helps to fix the lower base 3 in the groove 10. However, even if the surface 13 does not have an inclination inside the groove 10, the lower base 3 of the neck 1 will be held in the groove 10 due to the spring properties of the material and due to the conical surface 14. In order to prevent leakage in case of damage to the lower end of the neck 1, the lid may be provided with another annular seal, which must be located on the surface of the upper cylindrical section and 8 in close proximity or at a short distance under the lip-shaped annular seal 11, Claims of the invention The vessel has a truncated cone-shaped throat directed inward, with the large base facing upwards, with a pointed lower base and a lid, the inner part of which is located in the throat and has one below another cylindrical sections with a groove between them to accommodate the pointed base of the neck and a lip-shaped annular seal made in the upper section, adjacent to the mouth of the neck, which is characterized by the fact that in order to improve the tightness, the groove is made on the outer side of the upper cylindrical section, and the lip seal is located at the intersection of the upper boundary surface of the groove with the outer surface of the upper cylindrical section.
