## Abstract

A bottle with a dispensing device includes a cap having a female screw; a tubular element, coaxial with the female screw, having a lower end, which is closed by a bottom wall and projects inside the neck of the bottle; and a collar joined to the top of the tubular element through a tear-away. A hollow piston having an open lower end is inserted in the tubular element and is suitable for breaking through the bottom wall of the cap after the collar together with the tear-away ring has been removed. The hollow piston and bottom wall of the tubular element define a chamber containing a product. The lower end of the hollow piston has an inclined profile. Means are provided to stop the stroke of the hollow piston before the bottom wall completely detaches and prevent the hollow piston from rotating at the end of its stroke.

## Claims

### Claim 1

A bottle with a threaded neck having a dispensing device for releasing a product inside said bottle, said dispensing device comprising:
a) a cap having
a1) a female screw screwed onto the threaded neck of said bottle;
a2) a generally tubular element, coaxial with said female screw, having a lower end which projects inside the neck of the bottle, said lower end being closed by a bottom wall;
a3) a collar joined to the top of said generally tubular element through a tear-away ring;
b) a hollow piston inserted in said tubular element;
b1) the hollow piston having an open lower end and a head suitable for being housed in said collar;
b3) the hollow piston being suitable for breaking through said bottom wall of said cap after the tear-away ring is removed and the hollow piston is pushed linearly and downwardly without substantial rotational movement;
b4) the hollow piston defining, together with said bottom wall of said generally-tubular element, a chamber containing a product intended to be released in said bottle;
wherein
the lower end of said hollow piston has a generally inclined profile with respect to the plane defined by said bottom wall;
elements are provided which are suitable for stopping the stroke of said hollow piston before a complete detachment of the bottom wall occurs and for preventing said hollow piston from rotating at the end of its stroke.

### Claim 2 (depends on 1)

The bottle, according to claim 1, wherein
said elements suitable for stopping the stroke of the piston and for preventing the hollow piston from rotating at the end of the stroke comprise:
a circular groove arranged below the head of the hollow piston,
a tooth which projects from the upper edge of the generally tubular element.

### Claim 3 (depends on 1)

The bottle according to claim 1, wherein said generally inclined profile is shaped like a knife blade.
