A spout for a sealed carton for containing liquid products.

摘要

A sealed carton for containing liquid product such as milk, juice or the like comprising a spout made of an elastic material such as polyethylene resin in such a way that it comprises a main body (3) in the form of a pipe or case passed through the wall of the carton and a cover (2) for closing an opening of the main body (3), the main body and the cover being made as an integral body. The cover (2) and the main body (3) are interconnected with each other through a reduced-thickness separable portion (9) which is severed when the cover (2) is opened and through a reduced-thickness portion (7) which functions as an hinge portion when the cover (2) is opened. The main body (3) and the cover (2) have formed on the outer surfaces thereof an engagement element (11E) and an engagement recess (10E). When a tab (12) is pulled upwardly to open the cover (2), the distal end of the engagement element (11E) engages with the engagement recess (10E) so that the cover (2) is maintained in an opened position. When the cover (2) is closed, an engaging projection (8a) is brought into engagement with the inner surface of the main body (3), whereby the cover (2) is maintained in the closed position.
