The invention relates to the food industry, namely to a device for bottle sealing and drainage therefrom of liquid under pressure.The device consists of a closure element and an element for drainage of liquid under pressure. The sealing element is made with the possibility of fixation on the bottle neck (1) and includes a body (2) with inner thread. In the body (2) is made an axial through hole, wherein are placed a return valve (3) of spherical shape, an element that supports it (6) and a sealing collar (7) in the form of a funnel, which by means of the thread is attached with the upper base to the lower part of the closure element and with the lower base to a feed tube (8), located in the bottle. The element (6), supporting the return valve, made of food flexible plastic in the shape of petals, is placed with the lower base in the groove of the upper base of the sealing collar (7), while with the upper one is closely adjoined to the lower part of the valve. In the upper part of the closure element is made a multi-way thread for fixation of the liquid drainage element or a protective membrane. The liquid drainage element includes a body (4) with a spout for draining the liquid and a tap with pressure element (5) installed coaxially with the return valve (3), the supporting element (6) thereof, the sealing collar (7) and the feed tube (8) of the closure element. The lower end of the liquid drainage element is made with a multi-way thread with the possibility of its fixation on the closure element. |
