Abstract
The present invention relates to a closing system for a container, having a neck of the container and a closing body. The body wall includes at least one flexible tongue and at least one relatively stiff protrusion that, when the tongue is seated in the seating portion, arranges circumferentially sided to a circumferential stopping projection of the neck. In an imminent interference configuration, reached by relative rotation between the neck and the closing body, the protrusion interferes with the circumferential stopping projection for making an obstacle to the further rotation in the same direction of rotation, while the tongue is free from interferences with further obstacles to rotation.
Claims17
A trigger dispenser comprising:
- —a container;
- —a pump body suitable for being coupled to the container, wherein a suction means, a pumping means, and a dispensing means are seated therein, wherein:
- the suction means is suitable for sucking the liquid from the container and feeding it to a pumping chamber;
- the pumping means is actuated by a trigger suitable for influencing the liquid residing into the pumping chamber and ejecting it therefrom;
- and the dispensing means is connected to the pumping chamber and suitable for receiving the liquid ejected therefrom and dispensing it outside the dispenser;
- —a closing system comprising:
- a neck of the container, comprising an annular neck wall which develops about a main axis and delimits an opening to access inside the container, wherein the neck wall comprises:
- a) at least a first axial stopping projection, externally projecting from the neck wall;
- b) at least a first circumferential stopping projection, externally projecting from the neck wall;
- c) a seating portion, axially sided to the first axial stopping projection;
- and
- wherein the neck further comprises (i) a second circumferential stopping projection, separated from the first circumferential stopping projection and circumferentially spaced therefrom, or (ii) a second axial stopping projection, separated from the first axial stopping projection and circumferentially spaced therefrom, or both (i) and (ii);
- a closing body comprising:
- a) an annular body wall;
- b) at least one flexible tongue, internally projecting from the body wall, wherein the tongue is suitable for axially interfering snap-wise with the first axial stopping projection, thus arranging in the seating portion;
- c) at least one protrusion, more rigid than the tongue and axially spaced from the tongue, that, when the tongue is seated in the seating portion, arranges circumferentially sided to the first circumferential stopping projection;
- wherein said at least one protrusion is arranged below said tongue such that the protrusion is proximal to the edge of the annular body wall.
