<p>PROBLEM TO BE SOLVED: To facilitate opening of a hinge-lid at the head of an inner case by a method wherein the form of sleeve carton and the form of hinge-lid carton are combined and automatic opening and shutting is made possible for the head of the inner case by operation of pushing up and down the inner case. SOLUTION: On opening an automatic lid opening-and-shutting carton A that houses confectionery or the like and is composed of a sleevelike outer case 1 having a folded-down piece 16 at the upper end of its one face and a hinge-lid inner carton 2 having a lid cover being extended at its one face, the bottom of the inner case 2 is pushed up first of all, or the inner case 2 exposed through a hole provided at the side face of the outer case 1 is pushed up. Then, a turned-up lid cover piece 40d at the front end of the lid cover of the inner case 2 is connected with the folded-down piece 16 of the outer case 1 and with the inner case 2 pushed up further, the lid cover pulls a hinge- lid 3 toward the rear side and the hinge-lid 3 is opened. On the other hand, the hinge-lid 3 is automatically shut with the pushed-up inner case 2 returned to its original position.</p> |
