Description

  The present invention relates to a packaging body such as a packaging box and a ruled line structure for opening in the packaging body.

  A packaging box is provided with the outer peripheral wall which has each pair of side wall and an end wall, and each pair of inner flap and outer flap are arranged in a row by this outer peripheral wall. After opening the inner flap (bonding wall), the outer flap is bent, and these are bonded with a hot-melt resin (hot melt) which is an example of an adhesive, thereby sealing the opening of the outer peripheral wall. The package box sealed in this way has an effect that the sealed state can be reliably maintained, but has a drawback of poor opening workability.

  Therefore, the packaging box of Patent Document 1 is provided with an operation portion between both sticking portions at the front end of the outer flap, and is inclined from the operation portion toward the base end of the outer flap (a boundary line with a continuous outer peripheral wall). A folding curve for opening assistance is provided. This packaging box grips the operation part of the outer flap and pulls it outward to peel off the sticking part on the side of one inner flap while breaking the folding assist folding curve. The sticking part on the flap side is peeled off. That is, since the force for opening is concentrated on one of the pair of sticking portions and peeled in order, it can be opened with a small force, and workability can be improved.

  However, the packaging box of Patent Document 1 has a complicated structure because it is necessary to provide an opening flap with two or more folding lines on the outer flap, and there is still room for improvement.

In FIG. 5, the gripping portion 25 is shown with light ink, but nothing is applied to the actual packaging box 10. By pressing the gripping auxiliary pressing portion 21 inward from the outside in the sealed state, a space in which a finger can be inserted is formed on the inner surface side of the outer flaps 16A, 16B, 18A, 18B. Therefore, the grip part 25 located between the sticking parts 20A and 20B can be easily gripped.

  The folding assist folding curve 26 is provided on each outer flap 16A, 16B, 18A, 18B. This folding assist folding curve 26 is viewed from the base end (second folding curve 19) side, and the second sticking located on the right side from the base end side on the first sticking part 20A side on the left side. It extends toward the tip side on the side of the wearing portion 20B. And it extends inclining so that it may cross between these, without passing on a pair of sticking parts 20A and 20B. The folding assist folding curve 26 of the present embodiment is composed of lead rules provided with cutting lines 28 at predetermined intervals on the folding curve 27.

  The opening assist folding curve 26 is set so as to extend from the corners on the base end side of the outer flaps 16A, 16B, 18A, 18B toward the corners on the front end side located diagonally. Thereby, the both ends of the folding curve 26 for opening assistance are located outside pasting each sticking part 20A, 20B. In addition, the angle α formed by the second folding curve 19 that is the boundary line between the outer flaps 16A, 16B, 18A, 18B and the end walls 12A, 12B and the opening assist folding curve 26 may be as close to an acute angle as possible. it can.

  In this packaging box 10, after bending the side wall 11A with respect to the end wall 12A, the end wall 12B is bent with respect to the side wall 11B, and the adhesive margin 13 and the end wall 12B are adhered with a vinyl acetate emulsion adhesive. To do. Then, it is delivered to a predetermined manufacturer in a folded state in which the side wall 11A and the end wall 12B and the side wall 11B and the end wall 12A are positioned on a plane.

  In use, for example, the side walls 11A and 11B and the end walls 12A and 12B are expanded so as to form a square tube shape. Then, after bending the lower inner flaps 17A and 17B, the lower outer flaps 18A and 18B are bent so as to intersect. Thereafter, the lower flaps 17A, 17B, 18A, and 18B are stuck by hot melt so as not to be positioned on the folding assist folding curve 26. In this state, a predetermined product is received from the upper opening. When the product is stored, the upper inner flaps 15A and 15B are bent, and then the upper outer flaps 16A and 16B are bent. Thereafter, the upper flaps 15A, 15B, 16A, and 16B are attached by hot melt so as not to be positioned on the folding assist folding curve 26 as described above.

  When taking out the product stored by opening the packaging box 10, for example, as shown in FIG. 2, first, the auxiliary gripping pressing portion 21 of the upper inner flaps 15A, 15B is pushed downward (inward) from above. Then, the grip portion 25 of the upper outer flap 16B located on the grip assist pushing portion 21 is gripped, and the upper outer flap 16B is pulled upward (outward).

  As a result, the upper outer flap 16B is bent at the opening assist folding line 26 as a fulcrum. If it does so, the 1st sticking part 20A located in the front end side of the upper side outer flap 16B with respect to the folding curve 26 for opening assistance will peel by what is called a lever principle. At this time, the folding assist folding curve 26 is set so that the angle α formed with the second folding curve 19 is an acute angle, and therefore, sufficient labor saving can be achieved when the first sticking portion 20A is peeled off. Can be planned.

  Subsequently, when the upper outer flap 16B is pulled outward, the upper outer flap 16B bends with respect to the end wall 12B with the second folding line 19 as a fulcrum as the boundary line with the end wall 12B as shown in FIG. . If it does so, the 2nd sticking part 20B located between the 2nd folding curve 19 and the folding assist folding curve 26 will peel by what is called a lever principle.

  Next, as shown in FIG. 4, the adhering portions 20A and 20B of the upper outer flap 16A located on the opposite side are peeled in the same procedure. And the goods accommodated in the inside are taken out by opening the upper inner flaps 15A and 15B. Note that the upper inner flaps 15A and 15B may be opened in any order first.

  As described above, in the present invention, the operating force can be increased in the order of the first sticking part 20A and the second sticking part 20B simply by gripping the grip part 25 and operating the upper outer flaps 16A and 16B outward. It can be concentrated and peeled off in order. In addition, the sticking portions 20A and 20B can be peeled off using the so-called lever principle, with the folding assist folding curve 26 and the second folding curve 19 as fulcrums. Therefore, labor-saving regarding opening work can be achieved and opening workability can be improved reliably.

  Moreover, since the opening ruled line is constituted by one unfolding assisting folding line 26 that is inclined between the adhering portions 20A and 20B, the structure thereof is extremely simple. That is, since it is not necessary to provide a folding line or a cutting line with a complicated shape, it is possible to prevent the rigidity of the outer flaps 16A, 16B, 18A, 18B from being lowered.
