 In the carton according to the present invention, as described above, the peripheral edge of the plastic lid has an inner peripheral edge that can be in close contact with the inner peripheral surface of the box opening and an outer peripheral edge that can be in close contact with the outer peripheral surface of the box opening. Since the box and the box are provided with a predetermined gap between each other, when the lid is covered on the box, the opening edge of the box can be held between the inner and outer peripheral edges of the lid, and thereby the opening of the box can be held. Can be reliably sealed. Moreover, the strength of the opening of the paper box can be remarkably increased by these inner and outer peripheral edges.

Further, when a protrusion that can fit into a groove provided on the outer peripheral surface of the opening of the box is provided at a predetermined position on the inner peripheral surface of the outer peripheral edge of the lid, these groove and protrusion By combining and with each other, the lid can be more firmly attached and fixed to the opening of the box. Furthermore, since cut lines that can be cut when opening the lid are provided at both corners of the lid, when opening the lid, end portions of the lid on the opposite side of the both corners provided with these cut lines are opened. By holding the lid and pulling the lid apart from the opening of the box and lifting it, the cutoff lines at both corners of the lid can be cut, so that the lid can be easily opened widely. As described above, the carton according to the present invention is composed of the paper box and the plastic lid, and since it is not necessary to attach an opening frame to the opening of the box unlike the conventional case, after using the carton, It is easy to separate into a paper box and a plastic lid, respectively.
