and then provided with a screw cap
should. This screw cap must so when you press on
the bottle does not undergo any deformation of the neck, has more than two full threads, but even then it is
Leak tightness is not guaranteed and by the way, this is one
very expensive type of closure. Liquids can therefore hardly be sent in wide-necked plastic containers »

According to the invention it is now proposed that the bottle neck is increased so far and is designed at the mouth so that when cutting through the bottle neck, the upper part as
Stopper can be used. For this reason, the bottle must be manufactured in such a way that the bottle neck that remains has no mold seams on the inside. For better cutting of the stopper from the bottle neck, an annular groove is made on the same. At the consumer, the bottle is always with the cap up. The plug can also have a few bead rings on the outside, which give a very good seal. in the
