Bottle stopper

Abstract

The useful model is related to devices for temporary overlapping of access to a container, in order to prevent penetration of various substances from outside, and to prevent spillage of liquid from the container, particularly to plugs for bottles. The purpose of the useful model is to reduce materials consumption. The useful model is implemented as follows. The user overturns the bottle, with its neck facing the bottom, and sets it in a bottling system. In such case, the bottling system is equipped with an opposite part, e.g. a tube with edge, which is not perpendicular to the tube axis. The tube is inserted in hole and breaks the diaphragm under the effect of the weight of the bottle with liquid. Liquid is thus supplied to the bottling system. Therefore, if the device consists of a side wall, edge wall, the first lip and diaphragm, such a design ensures saving of the expensive material required to make the device (side wall, edge wall and the first lip), since the diaphragm is made from another material. It is also helpful when bottles with liquid are installed in a bottling system, due to opening the hole, i.e. by breaking the diaphragm under the effect of the weight of the bottle with liquid without the use of any additional load, i.e. by lesser efforts on the part of the user.

1 . A plug for a bottle, comprising:
 a side wall, edge wall and a diaphragm,   with the edge wall made as a disc with the first external surface and the first internal surface,   the edge wall having a hole coaxial with the edge wall,   the edge wall being connected along the perimeter with an edge of the side wall made as a cylinder,   the side wall ensuring an opportunity of fixing on neck of the bottle, with the first internal surface facing the side wall, the diaphragm connected with the edge wall from the side of the first internal surface,   thus ensuring overlapping of the hole,   further characterized in that the diaphragm is made from a film.   
     
     
         2 . The plug for a bottle according to  claim 1 , further characterized in that
 the edge wall is supplemented with the first lip made as a ring,   the first lip is connected by one of the edges with the edge wall from the side of the first internal surface along the perimeter of the hole, and   the diaphragm connected with the first lip from the side of the first lip opposite to the first internal surface.
