Abstract

The invention relates to a container, in particular, to closures for necks and drain openings of various vessels, in particular all-metal torsos, and provides an increase in ease of use. Supplying the plug with a ring 7 with an internal thread interacting with the sleeve 6 of the handle 5, which also has a thread, makes it possible to additionally compress the elastic ring element, which ultimately speeds up the process of closing and opening the hermetic vessel. 1 il.

Description

This invention relates to closures for openings and drain openings of various vessels, in particular all-metal thermoses.

The purpose of the invention is to increase the convenience of operation.

Supplying the plug with a ring with an internal thread, which interacts with the sleeve of the handle, also having a thread, allows these elements to further compress the elastic ring element, which ultimately speeds up the process of closing and opening the sealed vessel.

The drawing shows the proposed tube.

The stopper for hermetic sealing of vessels comprises a base 1 having a cylindrical protrusion 2 with an external thread and an emphasis 3 with a central hole. On the base there is an elastic annular element 4. The cylindrical protrusion 2 of the base interacts with the handle 5, which has an annular sleeve 6 with internal and external threads. On the outer side, the ring bushing is enclosed by a ring 7 with an internal thread. The direction of the threads of the ring bushing and the ring is opposite to the direction of the threads of the ring bushing and the cylindrical protrusion.

Cork works as follows.

When assembled, the plug is inserted into the opening of the neck so that the outer part of the stop 3 rests on it. When rotating the handle 5, the base 1 and the ring 7 move in opposite directions to each other and compress the elastic element 4, which deforms and closes the neck of the vessel, sealing it. In one revolution of the handle 5, the base 1 and the ring 7 come closer to each other by a distance equal to the sum of the steps of the threads with which they are provided. The elastic element 4 is compressed by the same amount.

The principle of the proposed plug is based on the fact that the elastic element 4 of the plug is inserted before the introduction of the latter into the vessel's throat by rotating the base 1 and the handle 5 to such an extent that it enters the neck with a slight friction or at least touches it. Under this condition, the interaction of the components will be as follows. Since the elastic element 4 is pressed against the neck, the ring 7 and the base 1, as the handle 5 rotates in the system, the following friction forces appear that have an effect on the components of the plug: the force of the thread of the handle 5, thread

if the rings 7 and the base 1, the frictional force of the ring 7 and the base 1 about the elastic element 4 and the frictional force of the elastic element 4 about the throat. The corresponding moments of the friction arise relative to the axis of rotation.

The moment of the friction force of the elastic element about the neck and the moment of friction of the ring and the base of the elastic element are much larger than the moment of the frictional force of the threads of the handle on the thread of the ring and the base of them. This is due to the fact that, firstly, the elastic element is made of rubber or rubber-based materials, the coefficient of friction of which in any of the materials is much greater than the coefficient of mutual friction of the materials of which the handles, the stop and the base are made (these parts are made from antifriction materials, usually plastic), secondly, the force of friction of the elastic element 4 on the throat and the force of friction of the ring and the base of the elastic element are applied on a much larger shoulder than the force of friction of the thread of the handle, thread and a base. Therefore, when the handle is rotated, the components that have a smaller moment of friction, i.e. the handle slides against the ring and base as it rotates. The ring, the base and the elastic element do not rotate, since the sliding of the elastic element relative to the neck and the slippage of the ring and the base relative to the elastic element are hampered by large friction moments.

Since the ring and the base do not rotate, as the handle rotates, its threaded surfaces move the translational rings and the base towards each other.
