An anti-spill device for liquid containers, in particular for dense or viscous liquids, consisting of a cup-shaped element (11) or under-cap, of elastic material, inserted in the spout (3) of the container and forming a liquid seal, withstanding a pressure at least equal to the pressure exerted by the weight of the liquid held in the container (1) on said cup-shaped element (11), so that the container can be overturned without there being any separation of the under-cap (11), which occurs only following an increase in the pressure inside the container, caused for example by squeezing the side wall (14) thereof, the under-cap (11) being connected, by means of a rod-shaped extension (20) to radial elastic fins (22), such as to avoid complete detachment of the anti-spill device from the container.

Cette invention concerne un dispositif anti-déversement pour contenants de liquides, en particulier de liquides denses ou visqueux, formé d'un élément en forme de cuvette renversée (11) en matériau élastique à insérer dans le goulot du contenant pour constituer un bouchon étanche capable de résister à une pression au moins égale à celle exercée par le poids du liquide présent dans le contenant (1), de sorte qu'au renversement du contenant, il n'y ait aucun risque de séparation de l'élément en forme de cuvette inversée (11) sauf sous une augmentation de la pression consécutive par exemple au fait d'écraser les flancs (14), l'élément (11) étant rattaché, par l'intermédiaire d'une extension en forme de tige (20), à des ailettes radiales élastiques (22) de façon à empêcher le détachement complet du dispositif anti-déversement.
