Benefits of technology
"The present invention provides a dose cap for a screw-cap container that has a reservoir of additive inside. The cap is easy to open and close, and it maintains the integrity of the additive throughout the distribution system. The cap has a spacer that breaks the end wall of the cup when it is forced to penetrate the cover, ensuring effective packaging for the additive. The cap is suitable for closing the container with which it co-operates in leaktight manner. The invention also provides a method for opening the reservoir and releasing the additive. The cap is designed to protect the additive from damage during transportation and use."
Problems solved by technology
That action can take place in untimely manner and without sufficient control to enable the cap to be sold separately from the liquid container and to guarantee that it remains intact all the way from the manufacturer to the user.

Embodiment Construction
[0025]In the figures, the cap shown comprises a first part 1 forming a cover with an end wall 2 and a side skirt 3 that is cylindrical or very slightly frustoconical, flaring downwards, with its end 3a remote from the end wall 2 being provided with inside tapping 4 having one or two threads. This end 3a is defined by an end edge 3b. Near the top, the skirt 3 of the cover is provided with an inside portion in relief 5 of sawtooth section with a downwardly-directed tip, that constitutes a first retaining means forming a role that is described below. At the junction between the end wall and the skirt, the cover possesses a second inside portion in relief 6 that defines a slope 6a and a groove 6b that likewise form second retaining means.
[0026]The dose cap also has a second part 11 in the form of a cup having an end wall 12 that is substantially plane and a side skirt 13. Perpendicularly to its plane, the end wall 12 carries a stud 14 that extends inside the skirt 13 and goes beyond the...

A dose cap for an additive for adding to a liquid contained in a container having a neck suitable for receiving a screw cap that includes a first part in the form of a cover possessing an end wall and a side skirt having its end remote from the end wall provided with an inside thread, and a second part in the form of a cup with an end wall and a side skirt, the cup and the cover possessing first snap-fastener device that co-operates to hold the cup in the cover in a first relative axial position with leaktight peripheral contact between them, a spacer extending inside the skirt of the cup from the end wall thereof towards the end wall of the cover to form an abutment limiting penetration of the cup into the cover beyond said first position, and said spacer including a device for breaking the end wall of the cup when the cap is forced to penetrate into the cover beyond said first position by thrust from the rim of the neck.
Description
[0001]The present invention relates to closure means for packaging—a bottle—for a liquid—typically a beverage—suitable for delivering an organoleptic, mineral, coloring, or taste complement to the liquid.BACKGROUND OF THE INVENTION[0002]There exist numerous devices enabling an additive to be introduced into a liquid, in particular a beverage, which additive is contained in a cap suitable for being placed on the neck of the bottle containing the beverage.[0003]Mention can be made for example of document FR 2 158 142 that discloses a hollow cap constituting a reservoir of flavoring, the base of the cap being formed by a wall that can be punctured and that constitutes the end wall of said reservoir, and the top of the cap constitutes a pusher suitable for pushing a perforator member contained inside the reservoir towards said base wall.[0004]Mention is also made of document WO 2007 / 006414 in which a dose is shaped as a hollow cap in which a pusher actuated from the outside (the top of ...
