Abstract
A double-layer container comprises an inner container made of plastic and having a bottom, and a cylindrical outer layer made of paper. The outer layer is sleeved outside the inner container, a locking structure is provided between the outer layer and the inner container to snap the outer layer on an outer peripheral surface of the inner container, and the outer layer is provided with a tear tab capable of tearing and destroying the outer layer. The double-layer container reinforces the strength of the inner container and the outer layer in a radial direction through an annular groove and an annular protrusion respectively, so that the overall strength is high, and quick recycle is realized through the tear tab provided on the outer layer.
