2. A metal bottle cap, consisting of a central body and an outer crown, wherein the central body seals the bottle with an open neck, and the outer crown is a whole, which is a central body and a bottle with a plurality of uninterrupted flexible teeth around the edge and fixed on the thread, and a certain number of flexible teeth are hooked on the bottleneck, and the number of teeth of the outer crown must be a multiple of the whole; And it should be between 29 and * * * 33 people.
3. The steel twist-off bottle cap is combined with the bottle. It says that the contents of the bottle are pressurized, including the bottle with open contents on the neck, which means that the opening means that the neck defines a circle, and four threads start from it, each thread starts from its own starting point and ends at one end. Finally, it said that there was a neck bottle, a central hat for the body that didn't work at the opening ceremony, an outer crown and integral showed that the central body was around the outer crown teeth. 33 continuous bending, in which the number of teeth fixed on the edge is all constrained, and the threads start to be different, at least one of which starts from the other three threads, and the threads with different numbers of teeth are integer multiples, so that people wearing hats with at most one tooth always say that they are at the beginning and end of alignment, thus reducing a trend. The contents of the cap screw itself tend to say that the leakage of the bottle has been removed before.
Hope to adopt
