Abstract
This application provides a universal liner, including a support portion and a backing portion. The support portion has several tangent lines arranged parallel to each other, dividing the support portion into several backing strips. The support portion also has two first folds, which are perpendicular to the tangent lines and located on opposite sides of the backing strips. Parts of the backing strips are folded inward along the two first folds towards one side of the support portion to form a receiving cavity. The backing portion consists of two pieces, each located on opposite sides of the support portion. A second fold is provided between the two backing pieces and the support portion. The two backing pieces are folded along the second folds to support the support portion, and the folding direction of the backing pieces is consistent with the inward folding direction of the backing strips. This application has a simple overall structure, low manufacturing cost, and strong versatility.
