ABSTRACT:
The stop device for cap threads is preferably applicable to plastic caps which are coupled by screwing on the corresponding neck of a bottle containing liquids.
The device consists of a thickening or projection (8) provided in the inner part of the cap (1), specifically in the intersection part between the side surface of said cap and the bottom of the same. When the cap (1) is screwed on the neck of the bottle this thickening (8) stops against the first thread (2') which the neck of the bottle has, constituting an obstacle resistant enough to prevent the cap (1) in its last screwing phase from continuing screwing on the neck.
