Abstract: A closure device for a container, particularly a bottle, has a stopper called the service cap, arranged at the end thereof, on which a closing flap pivots. The closure device is provided with a locking system and cooperates with a hole in the sealed closure, or can be opened by pivoting. The closing flap has an opening device to guarantee the complete pivoting of the closing flap on opening, by a constant force and a constant movement without manual action of the user, immediately after the same has carried out a voluntary manual operation on the closing flap which is limited to releasing the locking system thereof.

Abstract: The invention concerns a dispensing and closure system arranged at the top of a container, in particular a soft tube comprising a liquid or pasty product, which is delivered by pressing on the tube. The invention is characterized in that it consists of a valve comprising two concentric elements, one of which forms a mobile cylindrical delivery valve and the other forms a cylindrical body exiting from a plate linked to the tube. The two elements defined between them an annular gap through which the product passes. When a manual pressure is exerted on the tube, it causes the product to act directly on the delivery valve causing the latter to open, countering an elastic return member, so as to allow the product to escape from the tube, when the pressure is exerted thereon and to automatically close the delivery valve when the pressure is released, preventing the possible return of the product already dispensed from returning inside the tube.
