A leak resistant drinking cup has a diaphragm seal for normally closing an open top of a liquid container of the cup. The seal can be opened to permit liquid to flow past it and out of the cup upon application of a vacuum pressure by the person, typically a small child, drinking from the cup. The diaphragm seal has a peripheral edge margin that can be deflected upward by the vacuum pressure to open a path out of the drinking cup. A hold down rib may be employed to control the locations where the peripheral edge margin is permitted to deflect.
Cette invention concerne un gobelet anti-fuite qui comporte un joint à membrane obturant normalement la partie récipient dudit gobelet. Ce joint peut être ouvert et laisser s'écouler un liquide hors du gobelet lorsque la personne, généralement un jeune enfant, applique une dépression par succion. Le joint à membrane présente un bord périphérique qui peut être fléchir vers le haut sous l'effet de la dépression et ouvrir un passage hors du gobelet. Le gobelet peut présenter une arête de maintien permettant de localiser les points de flexion du bord périphérique.
