Description

  The present invention relates to a packaging container.

  Conventionally, a rectangular parallelepiped cardboard packaging container formed by assembling packaging materials has been known (for example, see Patent Document 1). In such a packaging container, a side wall portion is erected upward from each side of the rectangular bottom surface portion, and a pair of inner flaps and a pair of outer flaps are provided on the side wall portions via folding lines. Yes. After the pair of inner flaps are folded inward, the pair of outer flaps are folded inward to form an upper lid of the packaging container.

JP 2011-20708 A

  The packaging container as described above is transported in a state where the tips of the outer flaps are fixed with tape so that the folded outer flaps do not open. At the time of opening after transportation, the outer flap is unfixed by cutting the tape of the outer flap with a cutter or the like, and the outer flap is opened outward to take out the contents.

  Here, when the tape for fixing the outer flap is cut with a cutter or the like, depending on how the stored item is packed, the stored item may be cut by mistake and the stored item may be damaged.

  Then, an object of this invention is to provide the packaging container which can reduce the possibility that a contained item will be damaged accidentally at the time of opening of a packaging container.

  The packaging container according to the present invention forms a lid portion by being connected to a rectangular bottom surface portion, a side surface portion standing upward from each side of the bottom surface portion, and an upper end of the side surface portion, and being folded inward. A rectangular parallelepiped packaging container provided with a flap portion, wherein the flap portion includes an inner flap composed of first and second flaps facing each other in a first direction, and a second crossing the first direction. And an outer flap that is folded inward so as to cover the inner flap, and the inner flap is folded inward, and the front end of the first flap And the tip of the second flap is 10 mm or less.

  In the packaging container which concerns on this invention, the distance of the front-end | tip of the 1st flap folded inward and the front-end | tip of a 2nd flap is 10 mm or less. Thus, when the first flap and the second flap are close to each other, the upper portion of the accommodation space defined by the bottom surface portion and the side surface portion is substantially covered with the inner flap. The packaging container is such that the outer flap covering the inner flap is sealed and transported by a tape or the like, and the tape that seals the outer flap is cut and opened by a cutter or the like at the transport destination. Is substantially covered with the inner flap, so that the cutting edge of a cutter or the like that has cut the tape that seals the outer flap at the time of opening hits the inner flap instead of the container. For this reason, at the time of opening a packaging container, possibility that a damage will be damaged accidentally is very low.

  Moreover, it is preferable that the front-end | tip of a 1st flap and the front-end | tip of a 2nd flap are contact | abutting. By abutting, the upper part of the accommodation space defined by the bottom surface portion and the side surface portion can be effectively covered by the inner flap, and when the packaging container is opened, the contents are accidentally damaged. The possibility is further reduced.

  Moreover, it is preferable that the notch is formed in the front-end | tip of either or both of a 1st and 2nd flap. When the first flap and the second flap are close to each other, it is difficult to open the inner flap. However, the opening operation is performed because the notches are formed at the tips of the first and second flaps. It becomes easy. Further, since the notch formed at the tip serves as a mark indicating the inner flap, it is easy to distinguish the inner flap and the outer flap during packaging.

  The notch is preferably formed in a region excluding the center line of the inner flap in the second direction. The upper part of the center line of the inner flap in the second direction is often used as an opening position of the outer flap, that is, a place where a tape or the like for sealing the outer flap is provided. By forming the notch, it is possible to prevent a cutter or the like through the notch from being damaged when opening the opening.

  Further, notches are formed at the tips of both the first and second flaps, and the notch formed at the tip of the first flap and the notch formed at the tip of the second flap are: It is preferable that they are formed in regions opposite to each other with the center line of the inner flap in the second direction as a boundary. This facilitates the opening operation and improves convenience.

  The packaging container is preferably made of cardboard. By making the packaging container corrugated cardboard, it is possible to facilitate the packing work, the transporting work, and the opening work, and the present invention can be reliably implemented.

  ADVANTAGE OF THE INVENTION According to this invention, it can prevent damaging a contained thing accidentally at the time of opening of a packaging container.

It is a perspective view of a packaging container, and is a figure which shows the state which the 1st and 2nd inner flap closed. It is a perspective view of a packaging container, and is a figure which shows the state which the 1st and 2nd inner flap opened.

  The side surface portion 12 includes side surface portions 12a, 12b, 12c, and 12d that are erected upward (in the Z direction in the drawing) from the folding lines 21a, 21b, 21c, and 21d that are the sides of the bottom surface portion 11, respectively. Yes. The lengths (that is, the heights) of the side surfaces 12a, 12b, 12c, and 12d in the Z direction are the same. The side portions 12a and 12b are opposed in the X direction, and the side portions 12c and 12d are opposed in the Y direction. The angle formed by the side surfaces 12a and 12d with the fold line 23a as the fold line, the angle formed by the side surfaces 12b and 12d with the fold line 23d as the fold line, and the angle formed by the side surfaces 12b and 12c with the fold line 23b as the fold line The angle formed by the side surfaces 12a and 12c with the fold line 23c as the fold line is 90 degrees. In addition, the adhesion part 31 is provided through the bending line 23b on the opposite side to the side adjacent to the side part 12d of the side part 12b (refer FIG. 3). The adhesive portion 31 is folded 90 degrees inside with the fold line 23b as a fold line, and is adhered to the side surface portion 12c with an adhesive or the like.

  The lid portion 13 is formed by folding inwardly a flap portion including inner lid flaps 13a and 13b (inner flaps) facing in the X direction and outer lid flaps 13c and 13d (outer flaps) facing in the Y direction. Has been. The in-lid flap 13a (first flap) is connected to a fold line 22a that is the upper end of the side surface portion 12a, and is accommodated in a region defined by the bottom surface portion 11 and the side surface portion 12 (hereinafter referred to as an accommodation region). In a state where the object is accommodated, the folding line 22a is folded inward by 90 degrees. Further, the in-lid flap 13b (second flap) is connected to a fold line 22b that is the upper end of the side surface portion 12b, and the fold line 22b is a fold line in a state in which the contents are accommodated in the accommodation area. Folded 90 degrees inside. The detailed configuration of the lid flaps 13a and 13b will be described later.

  The outer lid flap 13c (third flap) is connected to a fold line 22c that is the upper end of the side surface portion 12c, and the fold line 22c is used as a fold line so as to cover the inner flaps 13a and 13b from the outside. Folded 90 degrees inside. Further, the lid outer flap 13d (fourth flap) is connected to a fold line 22d that is the upper end of the side surface portion 12d, and the fold line 22d is used as a fold line to cover the flaps 13a, 13b from the outside. As shown in FIG. The length of the outer side flap 13c in the short side direction (the length from the folding line 22c to the tip of the outer lid flap 13c) and the length of the outer side flap 13d in the short side direction (from the folding line 22d to the outer lid flap 13d The length of the outer flap 13c and the outer flap 13d are in contact with each other. The contact portion is sealed with a tape or the like along the X direction. In the present embodiment, the sides of the lid portion 13, that is, the lengths of the fold lines 22a, 22b, 22c, and 22d are the same, and the lid portion 13 is square, but is not limited thereto.

  Next, details of the bottom flaps 11a and 11b and the lid flaps 13a and 13b will be described. Since the bottom flap 11a and the lid flap 13a and the bottom flap 11b and the lid flap 13b have the same configuration, the lid flaps 13a and 13b will be described below.

  In the lid flaps 13a and 13b, the tip 13x of the lid flap 13a and the tip 13y of the lid flap 13b are in contact with each other when the flaps 13a and 13b are bent inward by 90 degrees. Therefore, when the packaging container 1 is viewed in a plan view with the flaps 13a and 13b inside the lid folded inward and the flaps 13c and 13d outside the lid opened as shown in FIG. 1, the entire storage area of the packaging container 1 is within the lid. Covered by flaps 13a and 13b.

  The length in the short side direction of the in-lid flap 13a (length from the fold line 22a to the tip 13x) and the length in the short side direction of the flap in the lid 13b (length from the fold line 22b to the tip 13y) The tip end 13x and the tip end 13y are in contact with each other on a line connecting the X-direction center of the fold line 22c and the X-direction center of the fold line 22d. Further, the present invention is not limited to this, and it is only necessary that the sum of the length in the short side direction of the in-lid flap 13a and the length in the short side direction of the in-lid flap 13b is equal to the fold line 22c or the fold line 22d.

  Further, a notch 50x that is cut out in a semicircular shape is formed at the tip 13x of the lid flap 13a. Similarly, a notch 50y cut out in a semicircular shape is formed at the tip 13y of the in-lid flap 13b. The tip 13x and the tip 13y are in contact except for the region where the notches 50x and 50y are formed.

  The notches 50x and 50y are formed in a region excluding a line connecting the Y-direction center of the fold line 22a and the Y-direction center of the fold line 22b (center line ax of the lid flaps 13a and 13b in the Y direction). Yes. Specifically, the notches 50x and 50y are formed in regions opposite to each other with the center line ax as a boundary, and the notch 50x is an area closer to the folding line 22c than the center line ax, and the notch 50y. Are formed in the region on the folding line 22d side with respect to the center line ax. The size of the notches 50x and 50y is such that about one or two human fingers can enter.

  Note that the tip 13x of the lid flap 13a and the tip 13y of the lid flap 13b do not necessarily have to be in contact with each other except the region where the notches 50x and 50y are formed. For example, the tips 13x and 13y may be in contact only in the vicinity of the center line ax of the lid flaps 13a and 13b in the Y direction, and the other regions may not be in contact with each other.

  Next, the effect of the packaging container 1 which concerns on this embodiment is demonstrated with reference to FIG.4 and FIG.5 in addition to FIGS. 1-3.

  In the packaging container 1 which concerns on this embodiment, the front-end | tip 13x of the flap 13a in a lid | cover folded inside and the front-end | tip 13y of the flap 13b in a lid | cover contact | abut.

  As shown in FIG. 4, in the conventional packaging container 100, the in-lid flap 113 a and the in-lid flap 113 b that are folded inward are largely separated. Therefore, only a part of the upper portion of the accommodation region T defined by the bottom surface portion 111 and the side surface portion 112 is covered with both the lid flap 113a or lid flap 113b and the lid flap 113c or lid flap 113d. Most of them were covered only by the outer lid flap 113c or the outer lid flap 113d. Therefore, when cutting with a cutter or the like the tape that fixes the contact portion between the lid outer flap 113c and the lid outer flap 113d with a cutter or the like at the time of opening, the contents immediately below the tape become the contents C. There was a case where the contents C were cut and the contents C were damaged. Moreover, in order to avoid such a situation, it is necessary to insert an intermediate plate between the contents C and the flap, and the work at the time of packing becomes complicated.

  In this regard, in the packaging container 1 according to the present embodiment, as shown in FIG. 5, the front end 13x of the in-lid flap 13a and the front end 13y of the in-lid flap 13b are in contact with each other. 12 is covered with both the lid flap 13a or the lid flap 13b and the lid outer flap 13c or the lid flap 13d. Therefore, when the tape that fixes the contact portion between the flap outside the lid 13c and the flap outside the lid 13d is cut with a cutter or the like at the time of opening, the flap 13a inside the lid or the lid is not located in the container C but directly under the tape. Since it becomes one of the inner flaps 13b, the cutting edge of the cutter or the like hits either the in-lid flap 13a or the in-lid flap 13b instead of the contents C. Thereby, at the time of opening of the packaging container 1, it can prevent that the accommodation thing C is damaged accidentally. This eliminates the need for a conventionally used intermediate plate and the like, simplifies the packaging operation, and reduces the amount of cardboard required for packaging.

  Further, the notch 50x is formed at the tip 13x of the lid flap 13a and the notch 50y is formed at the tip 13y of the lid flap 13b, so that the tip 13x and the tip 13y come into contact with each other and the inner flap Even when the opening is difficult, the opening operation can be performed by inserting a finger into the notches 50x and 50y, thereby facilitating the opening operation. Further, since the notches 50x and 50y serve as marks indicating the in-lid flaps 13a and 13b, it is easy to distinguish the in-lid flaps 13a and 13b and the outside-lid flaps 13c and 13d at the time of packing.

  Further, the notches 50x and 50y are formed in a region excluding the center line ax of the lid flaps 13a and 13b in the Y direction. The upper part of the center line ax is a place where the tip of the lid outer flap 13c and the tip of the lid outer flap 13d are in contact with each other, where a tape or the like for sealing the lid outer flap 13c, 13d is provided. By forming the cutout portions 50x and 50y while avoiding the locations, it is possible to prevent a cutter or the like that has cut through the cutout from opening and damaging the contents.

  Further, the notch 50x and the notch 50y are formed in regions opposite to each other with the center line ax of the lid flaps 13a and 13b in the Y direction as a boundary, so that the notch 50x and the notch 50y are formed. As compared with the case where the two are provided close to each other, the opening operation becomes easier and the convenience is improved.

  As described above, the in-bottom flap 11a and the lid flap 13a, and the bottom flap 11b and the lid flap 13b have the same configuration. That is, the tip 11x of the bottom flap 11a and the tip 11y of the bottom flap 11b are in contact with each other, and a notch 40x is formed at the tip 11x, and a notch 40y is formed at the tip 11y. Therefore, even if the opening operation is performed from the bottom surface portion 11 side, the above-described contents C can be protected by the bottom surface flaps 11a and 11b.

  Further, by making the packaging container 1 made of corrugated cardboard, the packing work, the transporting work, and the unsealing work can be facilitated, and the contents C can be reliably protected by the inner flap described above.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment. For example, in the above-described embodiment, the tip 13x of the in-lid flap 13a and the tip 13y of the in-lid flap 13b are in contact with each other. The distance between the tips of the opposing inner flaps on the center line ax of the inner flaps 13a and 13b may be 10 mm or less. In this case, the upper portion of the accommodation space defined by the bottom surface portion 11 and the side surface portion 12 is substantially covered by the lid flaps 13a and 13b, so that the tip 13x of the lid flap 13a and the lid flap 13b Similar to the case where the tip 13y is in contact, there is a very low possibility that the contents will be damaged when the packaging container is opened.

  Moreover, the notch part does not need to be provided, it may be provided only at one of the front ends of the opposed inner flaps, or may be provided at two or more locations at the front ends of the opposed inner flaps. There may be. That is, the number of notches is not limited.

  Further, the shape of the notch is not limited to a semicircular shape. Any hole of a size that can be inserted by a person's finger may be used, and the shape may be a square or a triangle.
