This invention relates to a container, namely to closures for vessels.

The aim of the invention is to expand technological capabilities by using a closure for closing vessels of different diameters.

The completion of the chamber with cylindrical and conical sections allows the closure of vessels with a wide range of neck sizes.

Fig, 1 shows a general view of the device, the vessel is not clogged; Fig 2 is the same, the vessel is blocked.

The shutter contains an elastic chamber made of elastic material, having a cylindrical section 1 for placement in a vessel and a conical section 2 to which the rod 3 is attached, integral with the chamber and having a liquid that exceeds the rigidity of the material of the chamber. The conical section has a handle 4, intended to enter it into a cylindrical and increase the internal pressure in the chamber. The camera has a collar of 5,

The shutter works as follows.

When the vessel 6 is blocked, a force is applied vertically downwards to the rod 3 (see FIG. 1). This force is transmitted to the conical section 2. The elastic walls of the section 2 begin to bend along the generatrix and the entire conical section 2 gradually joins into the cylindrical

section 1 (see figure 2);

The total internal volume of the chamber due to the above decreases, and the air (gas) pressure in it increases accordingly. It burst the walls of the chamber, providing

their tight tight fit to the walls of the vessel 6. The lower base of the cylindrical section 1 can

perform increased thickness to prevent strong deflection. The vessel is sealed.

When the vessel is uncorked, a force is applied vertically upwards to the rod (see Fig. 2), holding the valve with the vessel by the flange 5. The elastic side walls of the conical section begin to bend along the generatrix, and it is gradually pulled out of the cylindrical section 1 (see figure 1). At the same time, the total internal volume of the chamber increases, the gas pressure in it decreases. The force distributed over the area ceases to act on the side walls of the cylindrical section 1, as a result of which they do not bulge and move away from the walls of the vessel 6. Then the bolt is pulled out of the pourer,

is open.
