Description

  The present invention relates to a paper box such as a confectionery box that can be re-sealed after the tear strip has been cut and opened.

Conventionally, as a paper box for packaging confectionery, as shown in FIG. 7 , an inner lid flap 53 and an outer lid flap 54 are extended from the upper edge of the opposing side plate 51, and an end flap 55 is extended from the upper edge of the end plate 52, respectively. The outer lid flap 54 is provided with a lateral tear band 56 sandwiched between two parallel cut lines 57 where the saddle-shaped cut is interrupted, the end flap 55 is bent inward, and the outer side of the tear band 56 is exposed at the tip side. The lid flap 54 is bonded to the inner lid flap 53 and sealed.

In this paper box, when the tear strip 56 is torn from one end and the outer lid flap 54 is cut, the upper end surface is opened and opened as shown in FIG. 8 , and then the insertion piece 58 at the tip of the inner lid flap 53 is opened. Is inserted into the slit 59 of the outer lid flap 54, it can be resealed.

  However, in the case of the above-mentioned paper box, when resealing, the inner cover flap 53 is bent to be rounded, and the insertion piece 58 must be inserted into the slit 59 at a shallow angle, which is difficult to reseal. There is a problem.

  Therefore, an object of the present invention is to provide a paper box that can be easily resealed after the tear strip is cut and opened.

In order to solve the above problems, the present invention extends the inner lid flap and the outer lid flap from the upper edge of the opposing side plate, and extends the end flap from the upper edge of the end plate, respectively, and is sandwiched between the outer lid flaps by a score line. In a paper box that is provided with a lateral tear band, the end flap is bent inward, and the outer lid flap is bonded to the inner lid flap on the tip side from the tear band and sealed, and protrudes in an arc shape at the center of the front end of the inner lid flap A pressing piece is formed on each side of the insertion piece, and a recess is provided in the central portion of the cut line located on the base end side of the outer lid flap among the cut lines forming the tear band, and the base end of the press piece Insert a diagonal crease line from the back of the notch at the boundary with the insertion piece to the side edge, and the insertion piece has an arc-like crease line that curves to the proximal end over both side edges. It was placed, after tearing open the tear strip, outside the insertion piece in the position of the recess Push down the proximal portion of the flap is to that to re-sealing.

  In such a paper box, when re-sealing, it is only necessary to push the insertion piece below the outer lid flap at the position of the recess of the score line, bend the inner lid flap to be rounded, or make the insertion piece into a narrow slit. There is no need to plug in. In the resealed state, the insertion piece and the recess are engaged with each other, the mutual movement of the inner lid flap and the outer lid flap in the lateral direction is suppressed, and the box shape is stabilized.

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

  In this paper box blank, as shown in FIG. 1, a pair of side plates 1 and end plates 2 are alternately arranged, and a passage piece 3 is provided on the outer edge of one side plate 1. A bottom flap 4 is connected to the lower edge of each side plate 1, an inner lid flap 5 is connected to the upper edge of one side plate 1, and an outer lid flap 6 is connected to the upper edge of the other side plate 1. Yes. Further, end flaps 7 are connected to the upper and lower edges of each end plate 2.

  The outer lid flap 6 is provided with a lateral tear band 8, which is sandwiched between two score lines 9 in which hook-shaped slits are interrupted. A concave portion 10 is provided in the center portion of the cut line 9 located on the base end side of the outer lid flap 6 among the cut lines 9.

  An insertion piece 11 projecting in an arc shape is formed at the center of the front end of the inner lid flap 5, and a pressing piece 12 is formed on each side via a notch, and the width of the proximal end portion of the insertion piece 11 It is substantially equal to the width of the recess 10 of the score line 9.

  An oblique crease line 13 extending from the back of the cut at the boundary with the insertion piece 11 to the side edge is placed at the proximal end portion of the pressing piece 12, and the insertion piece 11 spans both side edges. An arc-shaped crease line 14 that is curved toward the proximal end is provided.

  As shown in FIG. 2, the pair of side plates 1 and end plates 2 are folded into a rectangular tube shape, and the passage piece 3 is attached to the opposite end plate 2 to assemble the blank and package products such as confectionery. A peripheral wall is formed by adhering to the inner surface, the lower end flap 7 is bent inward, the bottom flaps 4 are bonded together, and the bottom surface is closed. Thereafter, the product is stored in the box, the upper end flap 7 is folded inward, and the outer lid flap 6 is bonded to the inner lid flap 5 on the tip side from the tear band 8 and sealed.

  Then, when opening the sealed paper box, as shown in FIGS. 3 and 4, when the tear strip 8 is torn from one end and the outer lid flap 6 is cut, the outer lid flap 6 and the inner lid flap 5 are cut. Can be opened. In this opened state, the front end side portion of the outer lid flap 6 remains attached to the inner lid flap 5.

  Here, as shown in FIG. 5, in the outer lid flap 6, only the surface side of the paper material is cut so as to be parallel to the score line 9 having at least the recess 10 on the outer side of the tear band 8, and half-cut If the stop line 15 is inserted, the tearing of the paper material surface from the recess 10 is prevented by the break line 15 when the tear band 8 is torn, so that the appearance is not unsightly.

  On the other hand, when the paper box opened as described above is resealed, as shown in FIG. 6, when the insertion piece 11 is pushed below the base end side portion of the outer lid flap 6 at the position of the recess 10, The proximal end side portion of the outer lid flap 6 is sandwiched between the insert piece 11 and the pressing piece 12, and the inner lid flap 5 and the outer lid flap 6 are held in a closed state.

  At this time, in the inner lid flap 5, the pressing piece 12 is bent from the proximal end along the fold line 13, and the insertion piece 11 is bent along the fold line 14, so that the inner lid flap 5 is hardly bent. The insertion piece 11 can be easily inserted below the outer lid flap 6.

  In the re-sealed state in this way, the insertion piece 11 and the recess 10 of the score line 9 are engaged, and the mutual movement of the inner lid flap 5 and the outer lid flap 6 in the lateral direction is suppressed. It is stable and the peripheral wall is shaped like a square tube.

  Moreover, when opening from the resealed state, it is only necessary to pick and pull one of the pressing pieces 12. Thereby, since the insertion piece 11 slips out from the lower part of the outer lid flap 6 and the inner lid flap 5 and the outer lid flap 6 are disengaged, it can be easily opened.
