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

  This exterior cardboard box is used for packaging and display of products, and the blank shown in FIG. 1 has a pair of end plates 1 and side plates 2 alternately connected to each other at the outer end of one side plate 2. The passage pieces 3 are connected continuously, the inner bottom flap 4 is connected to the lower end of each end plate 1, the outer bottom flap 5 is connected to the lower end of each side plate 2, and the inner lid flap 6 is connected to the upper end of each end plate 1. The outer lid flaps 7 are connected to the upper ends of the side plates 2 respectively.

  One end plate 1 sandwiched between both side plates 2 extends obliquely outward and upward from both sides of a pushing piece 8 formed by making a cut in the middle lower part, and is slightly spaced from the ridgeline with both side plates 2 A zipper-type cut line 9 is formed to open upward, and the cut line 9 is extended so as to extend obliquely inward toward the distal end side of the inner lid flap 6, and the inside of the cut line 9 is cut off. It is set to 10.

  Further, the inner lid flap 6 is provided with a lock piece 11 which is cut from a cut line 9 and is connected to the cut piece 10. The lock piece 11 is formed of a zipper type cut from the cut piece 10 at the boundary. It can be separated along with the breaking of the line of sight 12.

  The lock piece 11 is formed with a pulling portion 14 connected to the front end side of the inner lid flap 6 via a hinge portion 13 sandwiched between two crease lines, and a locking portion 15 protruding to both sides thereof. Yes.

  An H-shaped notch is formed in the central portion of the hinge portion 13 so as to form a protrusion that prevents the pulling portion 14 from being bent back when the outer lid flap 7 is locked. The notch which escapes the thickness of the outer lid flap 7 is made. A crease line 16 is provided at the boundary between the pulling portion 14 and the locking portion 15.

  Both outer lid flaps 7 are provided with a cut line 17 that extends obliquely from a side edge facing the cut piece 10 and is bent in an L-shape toward a portion overlapping the lock piece 11 when sealed. The part which becomes the inside of the cut line 17 at the time of abutting is made into the cover cut part 18. FIG. The oblique part of the cut line 17 is a zipper type, and the part bent in an L shape is a perforation.

  Each pair of end plate 1, side plate 2, and passage piece 3 is provided with a tear band 20 made of a cut tape affixed to the back surface at an intermediate lower portion in the height direction.

  Both side plates 2 were formed with a U-shaped cut line facing in the opposite direction, so that the cut-out portions 21 of the tear band 20 were formed at intervals in two places and sandwiched between the cut-out portions 21. The retaining piece 22 is provided in the part.

  The stop pieces 22 are arranged so as to be alternately shifted back and forth in the assembled state in which the side plates 2 face each other with respect to the end plate 1 which is the front surface provided with the cut pieces 10, and packaging by making a cut line in the side plates 2. This prevents a decrease in pressure strength in the state.

  The upper cut line that forms the leading edge of the detent piece 22 is such that the bulging arc-shaped portions are repeatedly arranged in the horizontal direction, and the base portion of the detent piece 22 has a horizontal fold line 23 and an upward protrusion. A cut line forming the piece 24 is provided.

  When manufacturing a cardboard box from the blank as described above, the end plate 1 and the side plate 2 are bent along the boundary ruled line, and the passage piece 3 is attached to the opposite end plate 1 in a flat state. .

  Then, for example, when packaging a product such as a pouch containing retort food, as shown in FIG. 2, the pair of end plates 1 and side plates 2 are bent into a square cylinder to form a peripheral wall, and the inner bottom flap 4 and the outer The bottom flap 5 is folded in order, the bottom surface is closed with the adhesive tape T, the product is stored, the inner lid flap 6 and the outer lid flap 7 are folded in order, and bonded from the abutment portion of the outer lid flap 7 to the cut piece 10. Tape T is applied and sealed.

  On the other hand, when the product is displayed at the store, the pushing piece 8 is pushed in and picked up, and as shown in FIG. 3, the cut piece 10 is pulled up along with the breaking of the score line 9 to open the end face, When the lid cut portion 18 connected to the cut piece 10 with the adhesive tape T is pulled up along with the break of the cut line 17, the lock piece 11 is pulled up so as to be interlocked with the cut piece 10 with the hinge portion 13 as an axis.

  Here, the extraction hole of the lid cut portion 18 formed in the outer lid flap 7 has a width of a portion corresponding to the lock piece 11 equal to or larger than the width of the pull-up portion 14, and the engaging portions on both sides before bending. 15 is set to be narrower than the entire width of the lock piece 11 including 15.

  For this reason, as the lock piece 11 is pulled up, the engaging portion 15 is bent along the crease line 16 and the pulling portion 14 passes through the extraction hole of the lid cut portion 18, as shown in FIG. The stop 15 is restored and rides on the outer lid flap 7.

  Thereafter, the lock piece 11 is cut off from the cut piece 10 along the cut line 12, and the adhesive tape T is peeled off to remove the cut piece 10 and the lid cut portion 18, as shown in FIG. Since the lid flap 7 is pressed by the locking portion 15 of the lock piece 11, the top surface is maintained closed while the end surface is open.

  In this way, in the above-mentioned exterior cardboard box, the end face is opened by a series of operations accompanying opening, the rising of the outer lid flap 7 can be prevented, and the top surface can be kept closed. The product G can be shown from the opening on the end face and displayed with a good appearance while preventing dust from entering from the top surface with a simple operation at the store.

  Further, when displaying the product in the form of the cardboard box as a tray, the locking piece 22 is swung so as to be pushed into the box along the crease line 23, and the cut-out portions 21 on both sides of the locking piece 22 are moved. In a state where it can be easily picked, the tear strip 20 is pulled from the cut start portion 21, both end plates 1 are cut from the side plate 2, and the portion above the tear strip 20 is removed, as shown in FIG. In this way, most of the product G is exposed.

  At this time, even if the folding along the fold line 23 of the retaining piece 22 tries to return due to repulsion, it is prevented by the protruding piece 24 that rises separately from the retaining piece 22, and the retaining piece 22 is held in a bent state. Is done.

  In such a tray-like display state, the leading edge of the retaining piece 22 having a shape in which the bulging arc-shaped portions are arranged is engaged with the side portion of the product G, so that the product G is sequentially extracted from the front side. However, the product G is prevented from falling forward, and the beauty is maintained.

  In addition, in the said embodiment, although the surrounding wall became a square cylinder shape in the packaging state, the surrounding wall has a more polygonal cylindrical shape such as a chamfered portion provided at the ridge portion of the end plate 1 and the side plate 2. In the corrugated cardboard box, the same configuration can be applied as long as the inner lid flap 6 and the outer lid flap 7 are sequentially folded and sealed.

  Moreover, although the thing which put the score line 17 in the outer cover flap 7 and provided the cover cutting part 18 was illustrated, this is abbreviate | omitted and it corresponds to the extraction hole of the cover cutting part 18 from the beginning to the outer cover flap 7. A cutout portion may be formed, and the drawn-out portion 14 of the lock piece 11 may pass through the cutout portion. At that time, the bent locking portion 15 may be restored and ride on the outer lid flap 7.
