Abstract: A container cover prevents spillage of contents. In one embodiment, the container cover includes a flexible body having a first portion that can be stretched over a mouth of a container. The container cover also includes a second portion providing a periphery around the first portion that can contract against the sides of a container on which the container cover is placed to hold the cover in position. The first portion when stretched over the mouth of the container has an extension forming an area of slack for the container cover to allow the container cover to expand as a result of increased pressure within the container. The container cover further includes the first portion also including an aperture to receive a tube for withdrawing contents from the container. The first portion of the container cover includes a venting system. The venting system is provided by a valve.

Abstract: It shows a container cover that is generally Shown as (1). The cover comprises an inner portion (2) which stretches over and covers the mouth of a cup A. The inner portion includes a pierceable area (9) for receiving a tube or straw B. The inner portion includes a “teat” of material that is not drawn as tightly over the mouth of the container as the inner portion (2). This allows for a degree of slack in the cover. The inner portion (2) is bounded by an outer portion (3), which can be pulled down the sides of the cup A so securing the container cover (1) in place.
