<p><P>PROBLEM TO BE SOLVED: To provide a paper container which has a strong lock mechanism for a lid and a box, is reduced in the sink-down of a tab, and has a fine appearance. <P>SOLUTION: The paper container is composed of the box having an upper face opening, and the lid covering the opening. The box and the lid are hinged together at the back of the box to allow the lid to be opened and closed freely. The tab is formed on the front face of the lid to project via the base end of the tab, and a separation portion which is demarcated and perforated by an incision line is so formed on the front face of the box as to oppose the tab. The tab is fixed to the separation portion so that the separation portion is separated along the incision line upon opening the lid to form an engaging piece made of the tab and the separation portion combined together. A separation mark formed by the separation of the separation portion serves as an engaging hole via which the lid can be locked to the box. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
