A closure device for containers suitable for holding liquids may include: a collar adapted to be applied to a neck of a liquid container, the collar having a lip; an elastically deformable membrane, configured to connect to the collar and to close the liquid container, wherein the membrane is configured to rest upon the lip and to define a seal along the lip, and wherein the seal is at least partially releasable by pressure exerted by a mouth of a user; and first and second flanges. The first flange is formed as a single piece with the membrane. The second flange is fixed to the collar to be locked between the first flange and the membrane. The first flange includes: a first portion projecting out of the membrane; and a second portion projecting out of the first portion. The second portion is oriented perpendicularly to the first portion.

Closure devices for containers suitable for holding liquids

A closure device for containers comprises a lid having a spout () with holes (), a valve body () attached to the lid () and operable on the spout (). The valve body () comprises a cup-shaped element () having a blind bottom wall () and a side wall () that emerges from the bottom wall () and delimits an upper opening, the side wall () of the cup-shaped element () being made of a resilient material, and at least partially contacting a first sleeve () of the lid (), which is in fluid communication with the spout (). The side wall () of the cup-shaped element () contacts the first sleeve () in a fluid-tight manner and moves away from the first sleeve () in response to a negative pressure introduced through the spout ().
