And paste them together. Thereafter, the inner box 60 is pulled back to the outer box sleeve 50 until the upper sides of the two match. At this time, the pulling piece 57 is folded inside the warped portion 56 in the side panel 52 of the outer sleeve 50. As a result, a sliding carton C ₃ is formed.

The slidable carton C ₃ assembled in this way comprises an outer box sleeve 50 and an inner box 60 slidable therein, and the outer box sleeve 50 warps at the upper part of its wide side panel 52. A cut line α is formed on the left and right sides to form the portion 56, a traction piece 57 is provided on the upper side of the side panel 52, and a sticking piece 58 is extended to the tip of the traction piece 57. the box 60 is partitioned lid portion L ₃ for opening and closing a polygonal line b in the lateral direction at the top of the side panel 63 of the wide as a hinge, bonded in a state in which the traction piece 57 of the outer box sleeve 50 is bent inwardly The wearing piece 58 is attached to the upper part of the side surface of the lid portion L ₃ of the inner box 60.

To open the sliding carton C ₃ , the inner box 60 is pushed up with respect to the outer box sleeve 50. Then, as shown in FIG. 10, the lid portion L ₃ is opened by being rotated via the pulling piece 57. At this time, the bulging portions provided so as to protrude from the left and right sides of the bottom outer panel 61b of the inner box 60 serve as stoppers, and the inner box 60 is pushed up more than necessary with respect to the outer box sleeve 50. There is nothing.

Further, when the inner box 60 is pulled down with respect to the outer box sleeve 50 from the opened state shown in FIG. 10, the lid portion L ₃ is rotated in the direction of returning through the pulling piece 57 and closed. That is, the traction piece 57 is continuously provided on the side panel 52 top warp portion 56 of the outer box sleeve 50, so that the traction piece 57 is adhered to the side surface of the lid portion L _3, the inner box 60 pushed up · force pulled transmitted to the lid portion L ₃ without interruption, it is possible to maintain a tightly closed was state with largely open the lid portion L _3. Also, when closing the lid portion L _3, since the arc-shaped portion of the top panel 63a tip serves stopper from falling into is prevented.

In the sliding carton C ₃ shown in FIG. 10, the back side of the sticking piece 58 is placed above the folding line b in the middle box 60 without folding the sticking piece 58 connected to the pulling piece 57 of the outer box sleeve 50. The sticking piece 58 may be folded inward, and the front side of the folded sticking piece 58 may be stuck to the front side of the upper region of the folding line b in the inner box 60. Write did so that the gap of the outer box sleeve 50 and inner box 60 is somewhat smaller when closed lid portion L _3.

  As mentioned above, although the form for implementing this invention has been demonstrated in detail, the sliding carton by this invention is not limited to said form at all, and various in the range which does not deviate from the meaning of this invention. Of course, changes are possible.

  For example, in the above example, a description has been given of an example in which a sliding carton is formed using paperboard paperboard, but it is formed using synthetic paper (plastic sheet) or other materials depending on the application or other circumstances. You may do it.

  Since the sliding carton of the present invention can be easily opened and closed with one hand and has good portability, it can store products used in several times, such as board gum, stick-wrapped confectionery, band aids, and tobacco. It is used suitably for selling.
