[0010]

The conventional example shown in FIG.
At the time of opening, two operations of breaking and pulling are required, in which the perforation 11 for opening is pushed in, the perforation 11 is broken, and the semicircular portion below the broken front part 3 is pulled. There is an inconvenience that it cannot be opened by operation.

In the conventional example shown in FIG. 8, an opening sewing machine is provided in which a fingernail is hooked on a cut 4c and pushed downward, or the lower part of the front part 3 and the rear part 5 is gripped and pulled downward. It is necessary to break the eyes 3c and 5c, that is, to hook the claw or to grip the lower part of the paper carton and pull it down.
There is an inconvenience that breaking of the opening perforations 3c and 5c is not always performed smoothly due to deformation of the paper carton C or the like.

Further, the paper cartons B and C have the disadvantage that the positions of the perforations 11, 3 c and 5 c and the cuts 4 c are difficult to find in dimly lit places, and it is difficult to open quickly.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a paper carton of a seal carton type that can be easily and reliably opened even in a dark place by one-touch operation.
