<p>The head of a bottle blown integrally from polyethylene on the neck and the body of the bottle, has a lateral wedgeform, inclined surface on which the twist toggle fastener rests with its ball, closing the bottle outlet. At the other side of the bottle the twist toggle is attached by a link to the bottle neck. A plastic gap is fitted on the twist toggle for closing the bottle outlet when it is not in use. The side opening facilitates drinking with or without a straw as well as accurate pouring without spilling.</p> |
