Abstract
A wet wipe container having improved opening and improved tear resistance between the lid and the base among other features. The container includes a container base and a container lid that is connected to the container base. In one embodiment, the container lid has a guide ridge that extends downward into the interior of the container. The guide ridge permits the container lid to be in a partially open position and provides better alignment between the container lid and the container base during closing of the container. In another embodiment, the container includes a closure that has an upwardly extending tongue projection, a flattened grip area and an assistive region to increase the ease with which the container can be opened. The invention also relates to a container having a more tear resistant container lid. The container lid has a hinge channel of a primary thickness. The hinge channel has two end regions that are of a secondary thickness that is greater than the primary thickness. The increased thickness of the end regions resists the tearing that can occur in the lid after repeated opening and closing of the container.
