The invention relates to household products. It can be used for opening and emptying the standard plastic bottles of 1-1.5-2 l, which are filled with mineral water or carbonated sodas. A nut-body combination is a uniting component of a device. To the component is hinged or otherwise attached claws for covering a neck of plastic bottle below a standard collar. Into the nut-body a hollow shaft as a whole with a hollow handle is screwed. In the handle a closing-metering element is located. Into the hollow shaft below the nut a cone cutting-pushing nozzle is screwed and tightly fixed. When the shaft rotates and the claws are pressed against the collar, the nozzle cuts without no waste a hole in the cover of bottle. Due to the conicity, the nozzle constantly spreads the edge of hole and provides a sealing pressing. The bottle with the device firmly pressed against it is overturned with the neck directed down and a closing-metering element is opened. Through the cavities a carbonated beverage under pressure leaves the bottle, and free gas remains in the bottle. |
