Description

  The present invention relates to a paper packaging box in which a plurality of inner boxes are accommodated densely.

  2. Description of the Related Art Conventionally, paper packaging boxes in which articles are stored in a plurality of inner boxes and a plurality of inner boxes are stored densely have shapes shown in FIGS. In FIG. 8 and FIG. 9, five inner boxes 2 having a flat rectangular shape with a rectangular plane are tightly accommodated inside the box body 3 of the rectangular paper packaging box 1. An upper lid comprising inner lid flaps 6a, 6b and outer lid flaps 7a, 7b extending upward continuously from the side surfaces 4a, 4b, 5a, 5b on the upper sides of the four side surfaces 4a, 4b, 5a, 5b of the box body 3 A forming flap is formed. Then, after folding the inner lid flaps 6a and 6b onto the inner box 2, the outer lid flaps 7a and 7b are folded onto the inner lid flaps 6a and 6b to close the upper opening of the box body 3 as shown in FIG. And the inner box 2 is packaged.

  However, in the paper packaging box 1 shown in FIGS. 8 and 9, when the upper lid forming flaps 6a, 6b, 7a, 7b are opened and the inner box 2 in the box body 3 is taken out as shown in FIG. Since the inner box 2 is tightly accommodated in the box body 3, it is impossible to put a finger on the inner box 2, and for this reason, the inner box 2 cannot be taken out from the box body 3.

  Therefore, in the case of the paper packaging box 1 as described above, the box body 3 is usually torn and the inner box 2 is taken out. For this reason, the paper packaging box 1 cannot be reused. Was.

  In order to make it possible to easily take out the interior case that is tightly accommodated in the exterior case, a tongue piece having an opening of a size of one finger is formed by pressing the interior case. Some are provided (see, for example, Patent Document 1).

In addition, two parallel cuts are made across the side plate on the short side and the upper lid forming flap connected to the upper end of the side plate at the upper end of the cardboard packaging box. A folding line parallel to the connecting line of each side plate and the upper lid forming flap is formed between the end portions of the parallel cuts and between the two parallel cut ends on the upper lid forming flap side. In the portion sandwiched by the parallel cuts, a continuous line of each side plate and the upper lid forming flap and a straight folding curve are formed, and further, this folding curve and the two on the upper lid forming flap side are formed. Forming another folding line parallel to each folding line between two parallel cuttings between the folding lines between the ends of the parallel cuts, and opening the flap for forming the upper lid on the short side To form a space for inserting a finger in the continuous line portion. There is (for example, see Patent Document 2).

  However, in Patent Document 1, when an interior case is taken out from the exterior case, the article is handled as a product while being accommodated in the interior case in order to press the tongue provided on the interior case to form an opening. In addition, an interior case in which an opening has been formed cannot be used as a product. In general, articles are often handled as products while being stored in an interior case, and therefore cannot be applied in such a case.

  Further, in Patent Document 2, two parallel cuts are provided in order to form a space in which a finger can be inserted in the continuous line portion by opening the flap for forming the upper lid on the short side, and the two parallel cuts are provided. In order to form the space, the folds need to have creases in different directions, and for this reason, the folds are formed along the folds. Therefore, it is necessary to cut off the different sides of the cardboard in the thickness direction, and there is a problem that the structure is complicated and the production takes time and labor.

  Further, in Patent Document 2, since the space is formed in a continuous line portion between the side plate and the upper lid forming flap, when the packaged items are accommodated in multiple stages inside the box body, However, there is a problem that even if the uppermost package item can be taken out, the lower package item cannot be taken out.

  The present invention has been made in view of the above circumstances, and a plurality of inner boxes densely accommodated in the box body can be easily taken out with a simple configuration, and the inner boxes are accommodated in a plurality of stages. An object of the present invention is to provide a paper packaging box in which the lower inner box can be easily taken out.

  The invention according to claim 1 is a paper packaging box in which a plurality of inner boxes are tightly accommodated in a box body and are closed by an upper lid forming flap connected to the upper end of the side surface of the box body. An insertion hole for inserting a finger is provided in at least one of the upper lid forming flaps, and the upper lid forming flap provided with the insertion holes can be easily separated from the side surface of the box body provided continuously with the insertion hole. The present invention relates to a paper packaging box characterized in that a cut line having a required width is provided to form an opening piece.

  The invention according to claim 2 is characterized in that, when the upper lid forming flap comprises an inner lid flap and an outer lid flap, the opening piece is formed on the inner lid flap side. The paper packaging box.

  The invention according to claim 3 is characterized in that, when the inner box has a planar rectangular shape, the opening piece is formed on the upper lid forming flap side corresponding to the long side of the inner box. This relates to the paper packaging box described in 1. above.

  The invention according to claim 4 is characterized in that the length of the cut line of the opening piece portion is set according to the number of steps of the inner box accommodated in the box body. This relates to the paper packaging box described in 1.

  The invention according to claim 5 relates to the paper packaging box according to any one of claims 1 to 4, wherein a reinforcing material is attached to the opening piece.

  According to the present invention, an insertion hole for inserting a finger is provided in at least one of the upper lid forming flaps, and the upper lid forming flap provided with the insertion holes extends from the insertion hole to the side surface of the box body. Since the opening piece is formed by providing a cut line with the required width for easy separation, when removing the inner box from the box body, open the upper lid forming flap and insert your finger into the insertion hole. If the upper end of the opening piece is pulled in a direction perpendicular to the surface of the inner lid flap, it will be cut along the inner lid flap and the cut line on the side surface, and the opening piece will be separated from the outside. Since the upper part is exposed, if you put your finger on the exposed part of this inner box and rub it up, the inner box will be lifted up by the frictional force of the finger, so that you can grasp the inner box Hold the inner box firmly to There is an effect that can be taken in. Further, when one inner box is taken out, a space is formed in the box main body, so that the other inner box can be easily grasped and taken out by being inclined toward the space.

  Further, when the inner box is accommodated in a plurality of stages inside the box body, the upper end of the opening piece is further pulled so that the lower inner box is exposed from the upper surface by a required length. By adjusting the cut-off length of the portion, there is an effect that the lower inner box can be easily taken out in the same manner as described above.

  In addition, since the opening piece is formed on the inner lid flap side, when the paper packaging box is used again, the opened opening piece is returned to the original state before the separation and the box main body is again separated. When the inner box is housed inside and closed and wrapped by the inner lid flap and the outer lid flap, the opening piece that is formed on the inner lid flap and then separated and then returned to the original position is the upper part by the outer lid flap. Since it becomes a state integrated with the box main body by being pressed from the side, there is an effect that the paper packaging box can be reused satisfactorily without forming an opening on the side surface.

  Furthermore, the strength of the opening piece can be increased by applying the reinforcing material to the opening piece in advance, so that the opening piece can be broken even if the width of the opening piece is reduced. Moreover, there is an effect that the strength of the paper packaging box can be kept high by forming the opening piece portion narrowly.

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

  1 to 5 show an example of a form of a paper packaging box for carrying out the present invention. The basic configuration is substantially the same as that of the paper packaging box shown in FIGS. 8 and 9, and FIG. The same components as those shown in FIG. 9 are denoted by the same reference numerals.

  As shown in FIG. 1, inner lid flaps 6a, 6b are attached to the upper ends of side surfaces 4a, 4b, 5a, 5b of a box body 3 such as cardboard, etc., in which a plurality of inner boxes 2 are tightly accommodated in the box body 3. In the paper packaging box 1 in which the flaps for forming the upper lid composed of the outer lid flaps 7a and 7b are continuously provided, a finger is inserted into one of the inner lid flaps 6a and 6b (inner lid flap 6a in the figure). And a cut line 9 having a required width that facilitates separation from the insertion hole 8 to the side surface 4a of the box body 3 where the inner lid flap 6a provided with the insertion hole 8 is connected. , 9, and the opening piece 10 can be formed by the insertion hole 8 and the cut lines 9, 9. At this time, the cut lines 9 and 9 are perforated cutting lines, for example, and can be easily separated along the cutting lines.

  In FIG. 1, the inner box 2 has a planar rectangular shape, and the opening piece 10 is formed on the inner lid flap 6 a side corresponding to the long side of the inner box 2. The opening piece 10 may be provided so as to correspond to any of the upper lid forming flaps 6a, 6b, 7a, 7b depending on how the inner boxes 2 are arranged, and if necessary, two openings are provided. The opening piece 10 may be provided as described above.

  Furthermore, as shown in FIG. 2, when the inner box 2 is accommodated in a plurality of stages (two stages in FIG. 2) inside the box body 3, the lower ends of the cut lines 9, 9 of the opening piece 10 are The length is set to extend from the upper surface of the lowermost inner box 2 to the lower part.

  The operation of the above embodiment will be described below.

  As shown in FIG. 1, a plurality of inner boxes 2 are tightly accommodated in a box body 3, and the inner lid flaps 6a and 6b are folded on the inner box 2 and then the outer lid flaps 7a and 7b are folded on the inner lid. The upper opening of the box body 3 is closed by folding on the flaps 6a and 6b, and the inner box 2 is packaged. At this time, the opening piece 10 is formed on the inner lid flap 6a side. The insertion hole 8 and the cut lines 9, 9 formed in the flap 6a are hidden by the outer lid flaps 7a, 7b, and only the cut lines 9, 9 on the side surface 4a are exposed on the outer surface of the paper packaging box 1.

  In order to take out the inner box 2 from the box body 3, first, the outer lid flaps 7a and 7b are opened upward (state shown in FIG. 1), and then the inner lid flaps 6a and 6b are opened upward (state shown in FIG. 2). .

  Subsequently, when a finger is inserted into the insertion hole 8 in FIG. 2 and the upper end of the opening piece 10 is pulled in a direction perpendicular to the surface of the inner lid flap 6a, the cut lines 9, 9 of the inner lid flap 6a and the side surface 4a are cut. As shown in FIG. 3, the opening piece 10 is separated to the outside and the upper part of the inner box 2 is exposed. At this time, when the inner box 2 is accommodated in one stage in the box body 3, as shown in FIG. 3, the opening piece 10 is formed so that the inner box 2 is exposed from the upper surface by a required length. Adjust the separation length.

  As shown in the plan view of FIG. 4, the opening piece 10 is separated to form a space in which the finger can be inserted into the inner lid flap 6a, so that the finger can be inserted into the exposed portion of the inner box 2 from this space. When the finger is applied and rubbed upward, the inner box 2 is lifted upward by the frictional force of the finger. If the inner box 2 is lifted even slightly, the inner box 2 can be gripped with other fingers, so that the inner box 2 can be grasped firmly and easily taken out.

  When one inner box 2 is taken out, a space is created in the box body 3, so that the other inner box 2 can be easily grasped and taken out by inclining toward the space.

  Further, when the inner box 2 is accommodated in a plurality of stages inside the box body 3, as shown in FIG. 5, the upper end of the opening piece 10 is further pulled so that the lower inner box 2 has a predetermined length from the upper surface. The separation length of the opening piece 10 is adjusted so as to be exposed as much as possible. Thereby, the lower inner box 2 can be easily taken out by the same taking-out method as that in the case where the first inner box 2 is accommodated.

  Further, when the paper packaging box 1 is used again, the separated opening piece 10 is returned to the original state before the separation. At this time, the separation surface along the cut lines 9, 9 of the opening piece 10 has irregularities, and the corrugated cardboard has a thickness, so that the state is maintained by returning to the original state. become. In this state, the inner box 2 is accommodated again in the box body 3, and is closed and packaged by the inner lid flaps 6a and 6b and the outer lid flaps 7a and 7b. At this time, the opening piece 10 formed on the inner lid flap 6a and separated and then returned to the original state is integrated with the box body 3 by being pressed from above by the outer lid flaps 7a and 7b. Therefore, the paper packaging box 1 can be reused satisfactorily without forming an opening in the side surface 4a.

  In the embodiment of FIG. 1, the case where the opening piece 10 is formed on the inner lid flap 6 a side corresponding to the long side of the inner box 2 when the inner box 2 has a planar rectangle has been described. On the contrary, the opening piece 10 can be formed on the side corresponding to the short side of the inner box 2. However, in this case, it is difficult to take out the inner box 2 satisfactorily only by providing the opening piece 10 corresponding to one of the short sides. For this reason, it corresponds to both of the short sides of the inner box 2. Thus, it is necessary to form the opening piece 10. However, this is not preferable because the structure is complicated and the strength of the box body 3 is also reduced.

  FIG. 6 shows another embodiment of the present invention, and shows a case where six rows of inner boxes are accommodated in two rows in the plane direction in the box body. In FIG. 6, the opening piece 10 is formed at a position corresponding to one row (right row) of the inner box 2 in the inner lid flap 6a. Also in the case of the form of FIG. 6, one inner box 2 can be taken out by the opening piece 10, and the other inner box 2 can be easily taken out.

  FIG. 7 shows still another embodiment of the present invention, and shows a case where a tape-like reinforcing material 11 is pasted on the opening piece 10 in advance. Various materials can be used for the reinforcing material 11, and the reinforcing material 11 may be affixed to the outer surface or the inner surface of the paper packaging box 1. As described above, the strength of the opening piece 10 can be increased by sticking the reinforcing material 11 to the opening piece 10, and therefore the opening piece 10 can be reduced even if the width of the opening piece 10 is reduced. Since the opening piece 10 can be formed narrowly without being cut, the strength of the paper packaging box 1 can be kept high.

  The paper packaging box of the present invention is not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the gist of the present invention.
