Child-resistant package

Abstract

A child-resistant package that can be difficult to open by a child but easily opened by an adult. The child-resistant package includes a box cover and a tray that is slidably received into the box cover. The box cover and the tray can be rectangular, such as the tray can fit into the box cover. The box cover has a first cutout in a side face and a second cutout that extends from the rear face to the bottom face of the box cover. A tab on a side wall of the tray that can protrude from the first cutout when the tray is fully inserted into the box cover and the open-top of the tray is covered by the top face of the box cover. One of the side edges of the box cover is provided with an outwards-protruding tab buckled in the cutout one to one correspondingly, the wall thickness of the outwards-protruding tab is equal to that of the tray, and one outwards-protruding tab deforms inwards in the opposite directions under the action of external force so that the outwards-protruding tab may be forced to be separated from the cutout and pushed out of the paperboard tray.
