| 摘要 |
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.
