  However, in the packaging box as described above, for example, if a large number of gift boxes are stored without gaps, when taking out the gift box, it is difficult to take out between the wall surface of the packaging box and the gift box, Since gift boxes that are frequently used in recent years have only the lower part of the lid inserted into a shallow body box, the lid may come off from the body box.

  Also, when the tape is peeled off at the time of opening, the connecting portion provided at the cut line at the end of the knob is difficult to cut, and the upper end of the end wall and the base of the inner flap are irregularly torn from the end of the knob to prevent resistance. There was also the problem of getting bigger.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a packaging box in which a tape seal can be easily opened and an article can be easily taken out.

  In order to provide the above problems, in the present invention, an inner flap and an outer flap are connected to the upper ends of each pair of end walls and side walls, and a score line is formed at the upper part of the end walls to form a finger insertion portion and a knob portion. In a packaging box that is sealed by putting the outer flap on the inner flap and then sticking the tape from the tip of the butted outer flap to the knob, the outer part of the knob is surrounded from the inner flap to the lower part of the end wall. Thus, a cut line is formed to form an incisable opening wall portion, and a handle hole communicating with the cutout hole of the knob is provided in the upper portion of the opening wall portion.

  In this packaging box, push the finger insertion part, put your finger into the extraction hole, pick the knob and pull the tape, and when the cut line of the knob reaches the handle hole, the knob will be removed from the packaging box. After separating and tearing off the tape with the knob and opening it, open the outer flap, put your hand into the handle hole, pull the opening wall part forward, and open the opening wall part along the cut line cut Thus, the article can be easily taken out by inserting a hand through the opening.

  First, a first embodiment of the present invention will be described with reference to FIGS.

  As shown in FIG. 1, the corrugated blank of this packaging box has a pair of end walls 1 and side walls 2 alternately arranged, a passage piece 3 is provided on the outside of one side wall 2, and each end wall 1 The inner flap 4 and the outer flap 5 are connected to the upper end and the lower end of the side wall 2, respectively.

  The upper end of one end wall 1 is provided with a cut line 6 with a connecting portion having an inverted U-shape, and a finger insertion portion 7 is formed on the inside thereof. A boundary portion between the upper portion on both sides of the finger insertion portion 7 and the inner flap 4 Two zipper-shaped cut lines 8 are put on the edge, and a knob 9 is formed between them.

  Further, from the inner flap 4 to the lower part of the end wall 1, a lateral perforated cut line 10 and a zipper-shaped cut line 11 starting from both ends thereof so as to surround the outside of the knob 9, The opening wall part 12 whose width | variety below from upper direction becomes narrow is formed, and the opening hole 12 is provided with the handle hole 13 which faces the terminal end of the score line 8 in the base part of the inner flap 4. As shown in FIG.

  To assemble such a blank and wrap the article, as shown in FIG. 2, each pair of end walls 1 and side walls 2 is bent into a square tube shape, and the passage piece 3 is attached to the opposite end wall 1. Then, a peripheral wall is formed, and the lower inner flap 4 and outer flap 5 are sequentially bent inward to close the bottom surface.

  Then, after the article is stored, the upper inner flap 4 and the outer flap 5 are sequentially bent inward, the outer flap 5 is overlaid on the inner flap 4, and the knob 9 of the end wall 1 is picked from the front end portion of the outer flap 5 abutted against. The top surface is sealed by sticking the tape T over the top.

  On the other hand, when opening the packaging box sealed as described above, as shown in FIG. 3, the finger insertion portion 7 is pushed in while the connecting portion of the score line 6 is cut, and the finger is put into the extraction hole. As shown in FIG. 4, the knob portion 9 is picked and the knob portion 9 is cut off from the end wall 1 and the tape T is peeled off from the outer flap 5 as the cut line 8 is cut.

  At this time, since the end of the score line 8 faces the handle hole 13, simply pulling the tape T, the knob portion 9 can be easily cut off without being randomly split at the end and stuck to the tape T. In the state, it is separated from the packaging box, and the cut hole of the knob 9 and the handle hole 13 communicate with each other.

  Next, when taking out the article in the box, as shown in FIG. 5, the pair of outer flaps 5 are opened, a hand is inserted into the handle hole 13, and the opening wall 12 is pulled up to the front, As shown in FIG. 6, the cut lines 10, 11 of the inner flap 4 are cut, the other hand is put on the edge of the cut line 10, and the opening wall portion 12 is further pulled forward and downward.

  As a result, as shown in FIG. 7, the opening wall 12 can be opened and the end wall 1 can be opened to the lower part. Therefore, even if a large number of gift boxes are stored in the packaging box without any gaps, the end wall A hand can be inserted from the opening of 1 and a hand can be put on the bottom of the gift box, and the gift box can be easily taken out of the packaging box.

  Moreover, in this packaging box, since the width | variety of the opening wall part 12 is large in upper direction and the cut line 11 is put so that it may become narrow toward the downward direction, the width | variety of the part which the wrist side of the opening part of the end wall 1 enters is wide. While ensuring, the fall of the compressive strength in a packing state can be suppressed.

  By the way, in this embodiment, even if the end wall 1 is opened to the lower part, the lower end of the opening wall portion 12 remains connected to the end wall 1. A perforated cut line may be provided so that the opening wall portion 12 can be excised.

  Moreover, although the cut line 10 to be inserted into the inner flap 4 is a horizontal straight line, it may be a fold line protruding in a V shape toward the tip end side of the inner flap 4 or a curve protruding in an arc shape.

  Further, the peripheral wall in which the pair of end walls 1 and the side walls 2 are continuously provided may have a shape such as an octagonal cylinder having a chamfered slope at the ridge.

  Next, a second embodiment of the present invention will be described with reference to FIGS. Since the basic configuration of the packaging box is the same as that of the first embodiment, only the parts different from the first embodiment will be described here.

  As shown in a blank state in FIG. 8, the cut line 11 of the packaging box has an Y-shaped cut having branching portions 11 a and 11 b extending in a bifurcated manner upward and an outer branching portion. A connecting portion is provided between 11b and the linear portion below it in consideration of strength and the like.

  Further, the finger insertion portion 7 is rounded so that a finger can be easily inserted, and a grip piece 13a is provided in the handle hole 13 to make it easy to put a hand.

  When this packaging box is also opened from the sealed state shown in FIG. 9, as shown in FIG. 10, the finger insertion part 7 is pushed in, a finger is inserted into the extraction hole, and the knob part 9 is inserted as shown in FIG. When the tape T is picked and the cut of the cut line 8 of the knob 9 reaches the handle hole 13, the knob 9 is separated from the packaging box, so that the tape T is peeled off together with the knob 9 and easily opened. it can.

  Then, as shown in FIG. 12, the outer flap 5 is opened, a hand is put into the handle hole 13, the opening wall 12 is pulled forward as shown in FIGS. 13 and 14, and the cut line 11 is cut. By opening the opening wall 12, as shown in FIG. 15, the end wall 1 can be greatly opened to the lower part, and a hand can be inserted through the opening to easily take out an article such as a gift box.

  Here, when the opening wall portion 12 is opened, the cut line 11 is diagonally formed in the end wall 1 so that the width of the opening wall portion 12 is wide at the upper side and narrows toward the lower side. The front liner breaks in a direction deviating outward from the score line 11, and the back liner attempts to break in a direction deviating inward from the score line 11.

  However, in this packaging box, since each incision in which the score line 11 is intermittent is formed in a Y-shape having branching portions 11a and 11b that are bifurcated toward the top, it tends to deviate between the incisions. The crevice of the front liner reaches the branch portion 11b of the next cut, and the crevice of the back liner that tries to escape inward reaches the branch portion 11a of the next cut.

  Therefore, the front and back liners are continuously broken without greatly deviating from the cut line 11, and even if the packaging box is tall and has a long cut line 11, the cutting resistance of the cut line 11 is significantly increased, After the opening of the wall portion 12, the liner of the end wall 1 is greatly curled and does not exhibit an ugly appearance in which the inner shin is exposed.
