Abstract
The invention relates to a stopper for a box-type container with air admission, consisting of four parts: a stopper, a seal, a mouth and a movable part. When the seal is removed by pulling the tongue, the stopper can be inserted into the mouth and move the movable part, producing two parts, one for the admission of air and one for the outflow of the liquid, in both cases perforating the plastic-aluminum film. By pulling the stopper outwards, the fingers of the user pressing on the fingerprints, the mouth opens, releasing the clip of the stopper and pouring the liquid out of the box without splashing or continuous gushing of liquid.
