INSERT FOR THE MOUTH OF A CONTAINER AND METHOD FOR PRODUCING A CONTAINER WITH SUCH A MOUTH
The invention relates to a mouth insert for a container (1, 1', 1"), comprising a ventilation duct (2, 2', 2") with a discharge tube (7. 7'). Said discharge tube (7, 7') is encompassed by a bottom (8, 8', 8") on the outside of its external surface with a ventilation duct connection orifice (12) and which is defined by a jacket (10, 10') sealing the inner wall of the container mouth (3, 3', 3") when the insert is successfully inserted into the mouth of the container (3, 3', 3"). The container mouth insert is formed in such a way that a groove-shaped collector duct encompasses the discharge tube (7, 7') once the insert has been successfully introduced into the mouth of the container (3, 3', 3"), wherein the collector channel bottom (8, 8', 8") is formed by the above-mentioned bottom (8. 8', 8") and the collector duct is used to transport dripping liquid (14, 15) to the ventilation duct (2, 2', 2"). A blow mandrel has a pre-blow mandrel (25) to calibrate a discharge opening, a secondary blow mandrel (24) to calibrate the mouth of the ventilation duct and a main blow mandrel (23) to calibrate the bottom of the collector duct (8"). A blow mold has an extension which corresponds in shape to a wall of the discharge tube. In a method to produce a plastic container (1") with the container mouth insert, a flexible plastic tube is blown up in the closed blow mold, the container (1") is separated from the oversqueezed plastic part (21) and the blow mandrel is inserted into the mouth of the container.
