Abstract

<P>PROBLEM TO BE SOLVED: To provide a packaging box which can be resealed easily after tearing off a tearing band to open and can be re-opened from the state easily. <P>SOLUTION: A tab part 9 is provided on the tip side of an inner lid flap 5 and an inserting piece 10 is formed by a cut from the body part 8 of the inner lid flap 5 to the tab part 9 and a vertical ruled line 11 is provided from the tip edge toward the cut of the inserting piece 10 on the center of the tab part 9 and a base end ruled line 12 of the tab part 9 is provided slanting to the tip side from the base part of the inserting piece 10 toward both sides. After it is opened by tearing the tearing band 13, the inner flap 5 is piled on an outer flap 6 and when a part of the inserting piece 10 is pushed downward, the tab part 9 of the inner flap 5 is bent as being raised upward and the inserting piece 10 separated from the tab part 9 is inserted in an inserting hole 15 to be re-sealed easily. When the tab part 9 is pulled up from the state, the inserting piece 10 is pulled out from the inserting hole 15 to be re-opened easily. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a packaging box that can be re-sealed after a tear strip is cut and opened.

  Conventionally, as a packaging box for confectionery or the like, as shown in FIG. 7, an inner lid flap 53 and an outer lid flap 54 are extended from the upper edge of the opposite 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 packaging 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 difference provided at the tip of the inner lid flap 53 is opened. When the insert piece 58 is inserted into a slit-like insertion hole 59 formed in the outer lid flap 54, it can be resealed.

  However, in the packaging box as described above, when resealing, the insertion piece 58 must be inserted into the insertion hole 59 at a shallow angle while bending the inner lid flap 53 so as to be rounded. There is a problem that it is difficult to seal, and there is a problem that it is not easy to pull out the insertion piece 58 from the insertion hole 59 when re-sealing from that state.

  Then, this invention makes it a subject to provide the packaging box which can be resealed easily after cutting | disconnecting and tearing a tear strip, and can be easily restarted from the state.

  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. A lateral tear band is provided, the end flap is folded inward, the outer lid flap is bonded to the inner lid flap at the tip side from the tear band, sealed, the tear band is torn, and the outer lid flap is cut and opened. In a packaging box that can be resealed when the insertion piece of the inner lid flap is inserted into the insertion hole of the outer lid flap, a knob is provided on the tip side of the inner lid flap, and the insertion piece is attached to the inner lid flap. It is formed by cutting from the main body to the knob, and a vertical ruled line is made in the center of the knob from the leading edge toward the notch of the insert, and the base ruled line of the knob is placed on both sides from the base of the insert It was tilted toward the tip side.

  In such a packaging box, after tearing the tear strip and opening it, the inner lid flap is overlaid on the outer lid flap, and when the insertion piece is pressed downward, the gripping portion of the inner lid flap is lifted upward. Since the insertion piece separated from the knob is inserted into the insertion hole, it can be easily resealed. Moreover, if a knob | pick part is pulled up from the state, an insertion piece will be extracted from an insertion hole, and it can be easily restarted and sealed.

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

  As shown in FIG. 1, in the paperboard blank of this packaging box, each 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.

  On the inner lid flap 5, a knob portion 9 is connected to the distal end side of the main body portion 8, and an insertion piece 10 is formed by cutting from the main body portion 8 to the knob portion 9. A vertical ruled line 11 is inserted in the central portion of the knob 9 from the leading edge toward the notch of the insertion piece 10, and the proximal ruled line 12 of the knob 9 extends from the base of the insertion piece 10 to both sides. And tilted to the tip side.

  The outer lid flap 6 is provided with a lateral tear band 13, which is sandwiched between two score lines 14 at which saddle-shaped incisions are interrupted. An insertion hole 15 is formed on the proximal end side of the tear strip 13, and the insertion hole 15 has a width in the insertion direction of the insertion piece 10 and corresponds to the distal end side of the insertion piece 10. The edge has a bulging arc shape.

  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 strip 13 and sealed.

  In this packaging process, since the overlapping relationship of the end flap 7, the inner lid flap 5, and the outer lid flap 6 is the same as that of the conventional packaging box, the existing packaging line owned by the packaging box user is not modified. Can be used as is.

  And when opening the packaging box sealed in this way, as shown in FIG.3 and FIG.4, when the tear strip 13 is torn from one end and the outer lid flap 6 is cut, the outer lid flap 6 and the inner lid flap 5 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.

  On the other hand, when resealing the packaging box opened as described above, as shown in FIGS. 5 and 6, the inner lid flap 5 is overlaid on the outer lid flap 6, and the portion of the insertion piece 10 is pressed downward. Then, the vertical ruled line 11 bends in the mountain fold direction, the proximal ruled line 12 bends in the valley fold direction, and the handle 9 of the inner lid flap 5 is bent so as to be lifted upward, and is separated from the handle 9. Since 10 is inserted into the insertion hole 15, it can be easily resealed.

  Further, when opening again from that state, when the finger is put on the lower surface of the tip of the knob 9 at the portion of the vertical ruled line 11 and the knob 9 is pulled up, the inner lid flap 5 is bent to be rounded. Since the insertion piece 10 is pulled out from the insertion hole 15 without doing, it can be easily re-sealed and an internal product can be taken out.

The figure which shows the blank of the packaging box with a resealable function which concerns on this invention The perspective view which shows the sealing state of a packaging box same as the above Perspective view showing the opening process The perspective view which shows an open state same as the above Perspective view showing the resealing process The perspective view which shows the resealing state same as the above The perspective view which shows the sealing state of the conventional packaging box with a reseal function The perspective view which shows an open state same as the above
