Abstract: A device for dispensing a liquid to a pasty product is placed at the open end of a rigid container and includes a manual dosing pump for dosing a predetermined amount of product to be dispensed. The device has a base member to be placed on the container, a push button with a dispensing spout capable of a pumping action against a bellow including an opening-closing system formed at the upper end of the bellow. The opening-closing system includes a first inner peripheral collar formed at the upper end of the bellow and associated with a second collar of the bellow that is concentrically arranged relative to the first one and inserted in the same groove of the push button, wherein a locking tab capable of blocking the opening protrudes from the collar.

Abstract: A method for carrying out ventilation in a multi-walled container of the type comprising a rigid external housing, inside which a flexible inner pocket for containing a product is arranged and connected to a withdrawal device without ventilation, the layers having no adhesion between the same such as to be able to be separated without difficulty and with air ventilation between the same, characterized in being obtained by means of molding a projection at the upper or lower part of the pre-form which is subjected to a first operation of cutting a sprue, then a second operation of cutting the projection in a region close to the base and/or the neck of the recipient for production and a third operation of separating the layers.

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: A system of delivering a liquid to pasty product is designed to be installed on a flexible tube on which the user acts by manual pressure to cause the product to come out. The system has a base element that is attached to the open end of the tube, a window associated with a strip that can be moved in opening, and a cap designed to cover the base element having opposite the strip an integral recess capable of allowing the deflection in opening of the strip.

Abstract: System (1) of delivering a liquid to pasty product, designed to be installed on a flexible tube (2) on which the user acts by manual pressure to cause the product to come out, characterized in that it comprises: a base element (3) that is attached to the open end (4) of the tube (2) and comprises a window associated with a strip that can be moved in opening, a cap (7) designed to cover the base element comprising opposite the strip an internal recess capable of allowing the deflection in opening of said strip.

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.
