  However, in the mail order box as described above, in the sealed state, the intermediate flap 54 may be lifted from the inner flap 53, and it may appear that there is a gap between the top surface and the inner space of the box. There is a concern that users may be worried about product quality.

  Further, when the front end side of the outer flap 55 is lifted in the sealed state, the insertion piece 56 comes out of the insertion hole 57, so that it may be opened unexpectedly.

  For this reason, in order to increase the safety in the distribution process, it is necessary to fix the outer flap 55 with a tape. However, in that case, the cost required for packaging increases, and a cutter knife or the like is required for opening, which makes the work The problem of becoming bothersome arises.

  Further, since the outer flap 55 is large enough to cover the entire top surface, there is a problem that the amount of corrugated cardboard used is increased.

  Therefore, an object of the present invention is to provide a mail-order box that can be reliably sealed without opening a gap on both sides of the top surface, can be easily opened, and can reduce the amount of material used.

  In order to solve the above-mentioned problem, in the mail order box according to the present invention, the side plate and the end plate are connected to each other through the ridge in the circumferential direction, and a tab is provided on the intermediate flap extending from one side plate, A tab hole is formed in each extending inner flap, a sealing insertion portion is provided on the front end side of the outer flap extending from the other side plate, an insertion hole is formed in the intermediate flap, and the intermediate flap is overlaid on the inner flap, Insert the tab into the tab hole, put the outer flap on the intermediate flap, and insert the sealing insertion part into the insertion hole so that it is locked in the sealed state, and put a tear strip on the part of the intermediate flap that is not covered by the outer flap When the intermediate flap is divided along with the pulling of the tear band, it is opened in a state where the tip side portion and the outer flap overlap with each other from the divided portion of the intermediate flap.

  Further, the tab is positioned at the tip corner of the intermediate flap, and a hinge line is inserted into the base of the tab. The hinge line is inclined from the inside to the outside of the intermediate flap so as to approach the base of the intermediate flap. If the tab hole is also tilted and the tab is bent along the hinge line and inserted into the tab hole, the hinge line stays away from the edge of the tab hole corresponding to the tip of the tab, and the tab It was made to follow the back of the inner flap.

  Further, a sealing mountain fold line is inserted into the outer flap at a distance from the base of the sealing insertion portion, and both ends of the sealing mountain folding line are located at the leading edge of the outer flap on both sides of the sealing insertion portion. Is bent so as to approach the base of the outer flap. When the sealing insertion part is inserted into the insertion hole while being bent along, the sealing insertion part is along the back surface of the intermediate flap and the sealing insertion part and both sides of the insertion hole It was made to engage.

  In the mail order box according to this invention, in the sealed state, since the tab of the intermediate flap is inserted into the tab hole of the inner flap, the intermediate flap does not float up from the inner flap and a gap is not generated on both sides of the top surface. The sales user can be given a sense of security regarding the hygiene of the product.

  In addition, if the outer flap is not bent so as to be contracted, the sealing insertion portion cannot be pulled out from the insertion hole, so that reliable sealing performance can be obtained without sealing with a separate tape.

  Then, it can be opened simply by splitting the intermediate flap by pulling the tear band, and when opening the top surface, the tab is smoothly pulled out from the tab hole, and the tip side portion and the outer flap are separated from the split portion of the intermediate flap. Can be raised in an integrated state, so that the top surface can be easily opened and the product can be taken out.

  In addition, the intermediate flap and outer flap can be set to short dimensions that do not reach each other's base, and the tab can be set within a range that does not protrude from the width and length of the intermediate flap, reducing the amount of corrugated cardboard used. Can streamline mail order packaging.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  This mail order box is formed from a cardboard blank shown in FIG. In this blank, the side plate 1 that forms the longitudinal direction of the peripheral wall and the end plate 2 that forms the width direction are alternately connected to each other, and the passage piece 3 is connected to the outer end of one side plate 1. A bottom plate 4 and a bottom plate 5 are connected to the lower ends of the two end plates 2, respectively.

  An inner flap 6 is connected to the upper end of each end plate 2, an intermediate flap 7 is connected to the upper end of one side plate 1, and an outer flap 8 is connected to the upper end of the other side plate 1.

  The front end positions of the inner flap 6, the intermediate flap 7 and the outer flap 8 are aligned in the blank, and the maximum length A from the base to the front end is about 3/4 of the width B of the end plate 2. ing.

  Tabs 9 are provided at the corners on both sides of the intermediate flap 7, and a ruled hinge line 9 a is placed at the base of the tab 9. The hinge line 9a is inclined from the inside to the outside of the intermediate flap 7 in a direction approaching the base of the intermediate flap 7, and a notch 9b reaching the hinge line 9a is made in the outer part of the base of the tab 9 ing.

  A tab hole 10 into which the tab 9 is inserted is formed near the base of each inner flap 6, the tab hole 10 is inclined corresponding to the tab 9, and the inside of the cut line forming the tab hole 10 is bent. It is set as the piece 10a. An end edge of the tab hole 10 corresponding to the tip side of the tab 9 bulges out in an arc shape in a direction corresponding to the base side of the tab 9, and a notch 10 b is formed in the outer end portion of the tab hole 10.

  At the center of the front end of the outer flap 8, a sealing insertion portion 11 protruding from both sides is provided, and cuts 11a are made on both sides of the base portion.

  Further, the outer flap 8 is provided with a sealing mountain fold line 11b spaced from the base of the sealing insertion portion 11, and the sealing mountain folding line 11b has both ends on both sides of the sealing insertion portion 11 and the tip of the outer flap 8. It is located at the edge and is curved in an arc shape so that the center portion approaches the base portion of the outer flap 8.

  Further, the outer flap 8 is filled with a sealed valley fold line 11c from the center of the front end of the sealed plug portion 11 to the central portion of the sealed mountain fold line 11b, and the sealed mountain fold line 11b and the sealed valley fold line 11c are stamped. It is a lead ruled with a cut.

  An insertion hole 12 into which the sealing insertion part 11 is inserted is formed in the intermediate flap 7, and the insertion hole 12 is formed on both sides of the arc-shaped elongated hole bulging toward the distal end side of the intermediate flap 7. It is assumed that a continuous cut 12a is made from the edge near the base.

  Further, a notch 6 a for avoiding a collision of the sealing insertion portion 11 when the sealing insertion portion 11 is inserted into the insertion hole 12 is formed on the distal end side of each inner flap 6.

  The intermediate flap 7 is provided with a tear band 13 that is sandwiched between zipper-type cut lines where the hook-shaped cuts are intermittently provided across the entire width of the intermediate flap 7 at a portion near the base that is not covered by the outer flap 8 in the sealed state. An arrow indicating the tearing direction is displayed at the picked portion at one end by cutting the cardboard from the surface to the middle of the thickness direction.

  In such a blank, the intermediate flap 7 and the outer flap 8 are set to short dimensions that do not reach each other's base in the assembled state, and the tab 9 is set to a range that does not protrude from the front end and both side ends of the intermediate flap 7. Therefore, the amount of corrugated cardboard used as a material can be suppressed, and mail order packaging can be rationalized.

  When assembling a blank as described above and packaging a mail-ordered product, as shown in FIG. 2, the pair of side plates 1 and end plates 2 are folded into a square tube shape, and the passage pieces 3 are opposite to each other. After the product is stored in the box from the opening on the top surface in a state where the peripheral wall is formed by sticking to the end plate 2 on the side and the bottom plates 4 and 5 are bent to form the bottom wall, the pair of inner flaps 6 are Bending in the opposite direction, the intermediate flap 7 is bent in a direction to overlap the inner flap 6.

  Along with this, as shown in FIG. 3, the tab 9 is inserted into the tab hole 10 while being bent along the hinge line 9a. At this time, when the tip of the tab 9 is hooked on the center of the bulging edge of the tab hole 10, the insertion of the tab 9 into the tab hole 10 can be easily started. It is inserted into the tab hole 10 to slide along the shallow angle at 10a.

  Then, as shown in FIG. 4, when the tab 9 is completely inserted into the tab hole 10, the notches 9 b and 10 b are engaged to prevent the tab 9 from coming out of the tab hole 10, and the hinge wire 9 a is connected to the tab 9. Since the tab 9 stays away from the bulging edge of the tab hole 10 corresponding to the front end side, the front end side of the tab 9 does not go so much downward, and is in a state along the back surface of the inner flap 6. For this reason, tab 9 does not collide with the goods stored in the inside of the box.

  Next, the mail order box is rotated 180 ° so that the side plate 1 facing the front of the boxing operator is replaced with the opposite one. In this state, as shown in FIG. 5, the outer flap 8 is bent along the sealing mountain fold line 11 b and the sealing valley fold line 11 c so that the center portion on the front end side is depressed, as shown in FIG. 6, Insert the part 11 into the insertion hole 12.

  Thereafter, when the folding of the outer flap 8 is rebounded and restored, the sealing insertion portion 11 is along the back surface of the intermediate flap 7, the notches 11a and 12a are engaged, and the sealing insertion portion 11 and both sides of the insertion hole 12 are Engage and lock in sealed state. When the product is shipped, the slip S is pasted on the surface of the outer flap 8 in such a sealed state.

  When sealed in this way, the tabs 9 on both sides of the front end of the intermediate flap 7 are inserted into the tab holes 10 of the inner flap 6, so that the intermediate flap 7 is lifted from the inner flap 6 and a gap is formed on both sides of the top surface. Therefore, it is possible to give a sense of security to the user of the mail order regarding the hygiene aspect of the product.

  Further, if the outer flap 8 is not bent so as to be contracted, the sealing insertion portion 11 cannot be pulled out from the insertion hole 12, and the slip S contributes to prevention of tampering. However, a reliable sealing property can be obtained, and the product can be prevented from being extracted during the distribution process.

  On the other hand, when the merchandise purchaser opens the mail order box, as shown in FIG. 7, the middle flap 7 is divided by pulling the tear strip 13 from the knob in the direction indicated by the arrow. Then, when a hand is put into the gap generated by the cutting of the tear band 13 and the divided intermediate flaps 7 are caused as shown in FIG. 8, the tip side portion and the outer flap 8 are separated from the divided portions of the intermediate flap 7. Are opened in a state of overlapping.

  At this time, the tab 9 has a divided middle portion because the hinge line 9a of the base portion is inclined and is engaged with the inner flap 6 only at the outer notch 9b along the back surface of the inner flap 6 in the sealed state. As the flap 7 is raised, the engagement with the inner flap 6 is easily released and the tab 7 is smoothly pulled out.

  And since it can raise | generate in the state which overlap | superposed and integrated the front end side part and the outer flap 8 from the division | segmentation part of the intermediate | middle flap 7, a top | upper surface can be opened easily, as shown in FIG. By opening the inner flap 6, the product can be taken out with the top surface fully open.

  In the above embodiment, the tab 9 is illustrated as being inserted into the tab hole 10 along with the pushing of the bent piece 10a, but the bent piece 10a is omitted and the tab hole 10 is completely punched. It may be removed.

  In addition, although the case where the sealed mountain fold line 11b is curved in an arc shape is exemplified, the sealed mountain fold line 11b may be bent in a V shape so that the central portion becomes a valley.

  In addition, in the intermediate flap 7, the tab 9 may be provided in a position and a direction as shown in each drawing of FIG. That is, as shown in FIG. 10 (a), the tab 9 may be projected straight from the hinge line 9a on both sides of the front end side of the intermediate flap 7, as shown in FIG. 10 (b). The tab 9 may be projected straight with the hinge line 9a at a position cut from both sides of the front end side of the intermediate flap 7 as a base.

  Moreover, as shown in FIG.10 (c), you may make it the tab 9 protrude sideward from the hinge line 9a of the both sides of the intermediate | middle flap 7, as shown in FIG.10 (d), The tab 9 may protrude laterally with the hinge line 9a at the position cut from both sides of the intermediate flap 7 as a base.

  Further, as shown in FIGS. 10 (e) and 10 (f), the tab 9 may be formed by cutting into the inside of the intermediate flap 7, and such a tab 9 extends along the base of the intermediate flap 7. The hinge line 9a may extend from the hinge line 9a toward the distal end side, or may extend laterally from the hinge line 9a extending from the base portion of the intermediate flap 7 toward the distal end side.

  In addition, when providing the tab 9 in the position and direction as shown in each figure of FIG. 10, the tab hole 10 needs to be formed in the inner flap 6 corresponding to the position of the tab 9, FIG.10 (c), When the tab 9 protrudes to the side as in (d), it is necessary to cut the side portion of the inner flap 6 that interferes with the tab 9 in the blank.
