Description

  The present invention relates to a packing apparatus and a packing material used when packing a long article, for example.

  Generally, when packaging (packaging) an article, a packaging box (packing device) as described in Patent Document 1, for example, is used. The packaging box described in Patent Document 1 includes a rectangular tube-shaped cover and a body box (packaging material) inserted into the cover. The bottom plate of the body box is formed with a plurality of section-like partition walls that are cut and raised on the upper surface side with a linear crease line portion having a predetermined length as a base point. And the packaging box (packing device) becomes the packing form which can convey an article | item by inserting in the cover the body box which mounted the several article | item on the bottom plate in the state partitioned off by the partition wall.

  Incidentally, in recent years, ink jet printers have been increasing in capacity of ink cartridges with an increase in ink consumption due to high-speed printing processing and improved productivity. Since the increase in the capacity of such an ink cartridge is performed in accordance with the shape of the cartridge holder mounting opening in the ink jet printer main body, the cross-sectional shape corresponding to the cartridge holder mounting opening in the ink cartridge remains the same as before. An ink cartridge having a shape extending in the longitudinal direction is widespread.

  When a long article such as an ink cartridge extending in the longitudinal direction is packed and transported in large quantities, for example, the interior body in the packaging box of Patent Document 1 can be used. That is, the partition wall is cut from the bottom plate of the body box, and a plurality of long articles are placed on the bottom plate in a state of being partitioned by the partition wall, and the long articles are respectively placed on the bottom plate. What is necessary is just to pack up the several body boxes in the state put in the box body, such as a cardboard box.

  In addition, in the packing state in which a plurality of body boxes on which long articles are placed are stacked, the tip of the partition wall cut and raised from the bottom plate of the lower body box to the lower surface of the bottom plate of the upper body box It is advisable that the edges abut. In this way, the partition wall functions as a load support portion, and the load of the long article placed on the upper body box and the bottom plate of the body box is placed on the bottom plate of the lower body box. It is possible to suppress direct application to a long article.

JP-A-8-104318

  By the way, when the partition wall is cut and raised from the bottom plate of the body box, a cutout hole having a shape and size corresponding to the partition wall is formed in the bottom plate, and a part of the hole edge of the cutout hole is It is comprised by the crease line part used as the root part of a partition wall. That is, the partition wall is in a state where its root portion faces a space region called a cutout hole, and therefore, the strength against the load is reduced to some extent as compared with a case where the root portion does not face such a space region.

  Therefore, when the load of the article placed on the upper box and the same box is applied to the partition wall cut and raised in the lower box among the plurality of boxes that are stacked at the time of packing When the load is large, the base portion of the partition wall that receives the load may fall below the bottom plate so as to hang down part of the hole edge of the cutout hole. As a result, in the lower body box, it is impossible to maintain the position mode in which the front edge of the partition wall protrudes upward from the upper surface of the article placed on the bottom plate, and the bottom plate of the lower body box There is a possibility that the article placed on the top may be deformed by receiving a load.

  In order to avoid such a concern, it is possible to suppress the load applied to the long article by interposing a cushioning material such as a cardboard board between the body boxes, but in that case There has been a problem that the cushioning material interposed between the body boxes increases the number of members.

  The present invention has been made in view of such circumstances, and the object thereof is to increase the number of members, and when the articles are packed in a stacked state while the articles are placed on the board portion, the present invention is provided. An object of the present invention is to provide a packing device and a packing material that can suppress deformation due to a load.

  In order to achieve the above object, the packing material of the present invention has a substrate portion on which an article can be placed, and the substrate portion can be a load supporting piece that can be cut and raised from a crease line portion that forms a straight line. Is cut and formed so as to have a tip edge portion parallel to the crease line portion, and the length of the crease line portion of the load support piece is shorter than the length of the tip edge portion. The article can be packed in a stacked state in which a load is applied to the end edge portion of the load supporting piece while the article is placed on the cut and raised substrate portion.

  According to the present invention, the length of the crease line portion serving as the root portion of the load support piece is set to the length of the tip edge portion, compared to the case where the length of the crease line portion and the length of the tip edge portion of the load support piece are the same. By making it shorter than this, the size of the cut-out hole that causes a decrease in strength against the load is reduced. Therefore, when the load support piece that has been cut and raised receives a load, the base portion of the load support piece may fall down so as to hang down part of the hole edge of the cutout hole below the substrate portion. It is suppressed. Further, the load can be stably supported in that the length of the tip edge portion serving as a support portion that receives the load in the load support piece is longer than the length of the crease line portion. Furthermore, since such a load supporting piece is cut and raised from the substrate portion, the number of members does not increase. Therefore, it is possible to prevent the article on the substrate part from being deformed by the influence of the load when the article is placed on the substrate part and packed in a stacked state without increasing the number of members.

In the packaging material of the present invention, the length of the crease line portion in the load support piece is not more than a quarter of the total length of the substrate portion in the direction in which the crease line portion extends.
According to the present invention, it is possible to restrict the size of the cutout hole that the base portion of the load support piece cut and raised from the substrate portion faces, and to secure strength against the load.

In the packing material of the present invention, the plurality of load support pieces are provided on the substrate portion so that the crease line portions of the load support pieces are positioned on the same line.
According to the present invention, by providing a plurality of load support pieces on the same line on the substrate portion, it is possible to improve the strength against the load as compared with the case where only one such load support piece is provided.

  In the packaging material of the present invention, the total length of the crease line portions of the load support pieces located on the same line is 60% or less of the total length of the substrate portion in the direction in which the crease line portion extends. .

  According to the present invention, it is possible to reduce the area ratio of the cut-out holes formed when each load supporting piece located on the same line as the entire substrate portion is cut and raised, and the substrate on which the load supporting piece is cut and raised The strength against the load at the portion can be ensured.

In the packing material of the present invention, the total length of the tip edge portions of the load support pieces is 70% or more of the total length of the substrate portion in the direction in which the crease line portion extends.
According to the present invention, when the load support pieces located on the same line as the entire substrate portion are cut and raised, the support portions that receive the load increase, and thus a stable support function with respect to the load can be ensured.

In the packing material of the present invention, the article is a liquid container that contains therein a liquid used in the liquid ejecting apparatus.
According to this invention, when the liquid container is packed as an article, the same effect as described above can be obtained.

The packaging device of the present invention includes the packaging material having the above-described configuration and a box that can accommodate a plurality of the packaging materials in the stacked state.
According to this invention, the same effect as the invention of the packaging material can be obtained.

And each long side board part 17 and each short side board part 18 are bend | folded upward so that each of the four sides of the board | substrate part 16 shown with a broken line in FIG. 2 may correspond to the folding lines L1 and L2. Thus, it is erected vertically with respect to the substrate portion 16.

  Further, the upper surface of the substrate portion 16 in the interior body 13 functions as a placement surface 16 a that can be placed in parallel with the three ink cartridges 14 lying down in the direction along the longitudinal direction of the substrate portion 16. Then, on the upper surface of the substrate portion 16 that functions as the placement surface 16a, the ink cartridges 14 are laid down one by one in the short direction of the substrate portion 16, and are divided into three sections that can be placed. In FIG. 2, a plurality of crease line portions 19 having a straight line shape (a total of six in this embodiment) indicated by broken lines are provided.

  On the mounting surface 16 a, each crease line portion 19 is located at the center position in the longitudinal direction of the substrate portion 16, and the front and rear intermediate positions between the center position and the fold lines L <b> 2 of the front and rear short side plate portions 18. These are formed to be paired with each other in the left-right direction. Then, the three crease line portions 19 formed at predetermined intervals in the longitudinal direction (front-rear direction) of the substrate portion 16 are formed so as to be positioned on the same straight line along the longitudinal direction of the substrate portion 16. ing.

  That is, on the placement surface 16a of the substrate portion 16, these six crease line portions 19 are separated in the lateral direction in which the ink cartridges 14 are placed one by one in the lateral direction in the substrate portion 16 ( It is provided in a state in which two rows are arranged three by one in the horizontal direction. Then, each crease line portion 19 provided at a position where the ink cartridges 14 are laid down one by one in the short direction of the substrate portion 16 to partition the places where the ink cartridge 14 can be placed is left and right when the substrate portion 16 is viewed in plan view. The crease line portions 19 in both rows are located on the parallel lines in a state of facing each other in the left-right direction.

  In addition, as shown in FIGS. 1 to 3, a load support piece 20 that can be cut and raised upward from each crease line portion 19 is provided on the substrate portion 16, and a tip edge portion 20 a parallel to the crease line portion 19 is provided. It is formed so as to have a cut. That is, the substrate portion 16 is provided with one load support piece 20 having the same shape and size at the center position in the longitudinal direction of the substrate portion 16 so as to form a pair on the left and right sides. The load supporting pieces 20 having the same shape and size are also provided at the left and right intermediate positions at the front and rear intermediate positions between the folding lines L2 of the side plate portions 18 respectively. The three load support pieces 20 formed at predetermined intervals in the longitudinal direction (front-rear direction) of the substrate part 16 are formed so as to be positioned on the same straight line along the longitudinal direction of the substrate part 16. .

  That is, on the placement surface 16a of the substrate part 16, these six load support pieces 20 are separated in the lateral direction in which the ink cartridges 14 are placed one by one in the lateral direction ( It is provided in a state in which two rows are arranged three by one in the horizontal direction. Then, the load support piece 20 provided at a position in which the ink cartridges 14 are laid down one by one in the short direction of the substrate unit 16 and the areas where the ink cartridges 14 can be placed are partitioned is left and right when the substrate unit 16 is viewed in plan view. The load support pieces 20 in the row are positioned on the parallel lines in a state of facing each other in the left-right direction. In addition, the continuous line regarding the load support piece 20 shown in FIG.

  As shown in FIG. 3, the load support piece 20 has a trapezoidal shape in plan view, and the length La of the crease line portion 19 that becomes the root portion of the load support piece 20 when cut and raised is upward in the load support piece 20. It is shorter than the length Lb of the front end edge portion 20a serving as a support portion that receives the load applied from (La <Lb). Further, the length Lc from the crease line portion 19 to the tip edge portion 20a in a state where the load supporting piece 20 is cut and raised is the length Lc of the state in which the long side plate portion 17 and the short side plate portion 18 are bent from the fold lines L1 and L2. The height is the same as the height of the long side plate portion 17 and the short side plate portion 18.

  Further, the length Lc from the crease line portion 19 to the tip edge portion 20a in a state where the load supporting piece 20 is cut and raised is slightly longer than the length in the cartridge thickness direction when the ink cartridge 14 is in the sideways state. It has become. Therefore, in a state where the ink cartridge 14 is placed sideways on the placement surface 16a of the substrate portion 16, the tip edge portion 20a of the load support piece 20 protrudes slightly upward from between the adjacent ink cartridges 14. It becomes. Further, in a state where the load support piece 20 is cut and raised from the substrate portion 16, a cutout hole 21 (a region indicated by hatching in FIG. 2) that is a space area having the same shape as the shape of the load support piece 20 is formed in the substrate portion 16. It is formed.

  Note that the length La of the crease line portion 19 and the length Lb of the tip edge portion 20a of the load support piece 20 formed by cutting and raising a part of the substrate portion 16 are the total length of the substrate portion 16 in the longitudinal direction. In relation, the following settings are made. That is, when a plurality of load support pieces 20 are provided in the longitudinal direction of the substrate portion 16, the total length Lb in the longitudinal direction of the tip edge portion 20 a of each load support piece 20 is the total length in the longitudinal direction of the substrate portion 16. The total length La of the crease line portion 19 is 60% or less of the entire length of the substrate portion 16 in the longitudinal direction. Incidentally, the length La of the crease line portion 19 in one load support piece 20 is ¼ or less, more preferably ５ or less of the entire length of the substrate portion 16 in the longitudinal direction.

  When the ink cartridge 14 is packed in the packing device 11 including the box body 12 and the interior body (packing material) 13 having the above-described configuration, first, the long side plate portion 17 and the short side plate portion 18 are provided on the substrate portion 16. The three ink cartridges 14 are respectively placed in a state of being laid down on the interior body 13 in a state where the load supporting pieces 20 are cut and raised with the crease line portions 19 as base points. Place on the surface 16a. Then, the interior body 13 with the three ink cartridges 14 placed on the placement surface 16a is inserted into the open box 12. Therefore, only one interior body 13 in which the ink cartridge 14 is placed is first housed in the box 12.

  Next, similarly to the first interior body 13, the second interior body 13 in a state where the three ink cartridges 14 are respectively placed on the placement surfaces 16 a is inserted into the box body 12. Then, the second interior body 13 inserted into the box body 12 is accommodated so as to be stacked on the first interior body 13 already accommodated in the box body 12. At this time, the front end edge 20a of the load support piece 20 in the first interior body 13 located on the lower side is the lower surface 16b of the substrate portion 16 in the second interior body 13 located on the upper side (see FIG. 1). Abut.

  In the load support piece 20 having a configuration in which the length Lb of the tip edge portion 20a of the load support piece 20 is longer than the length La of the crease line portion 19, the length of the tip edge portion 20a is shorter than the length of the crease line portion 19. Compared with the load support piece of the structure, since there are many areas which contact | abut the lower surface 16b of the board | substrate part 16 in the upper interior body 13, the support force which supports the upper interior body 13 is strong. Therefore, the load of the upper interior body 13 can be stably supported by the load support piece 20 provided on the lower interior body 13. Further, since the length La of the crease line portion 19 of the load support piece 20 is shorter than the length Lb of the tip edge portion 20a, the cutout hole 21 formed by raising the load support piece 20 (that is, free conversion). The size of the space area that causes a decrease in the strength is reduced. Therefore, when the load support piece 20 cut and raised from the substrate portion 16 receives a load, the root portion of the load support piece 20 hangs down part of the hole edge of the cutout hole 21 below the substrate portion 16. In this way, the depression is suppressed.

  This is not limited to the first and second interior bodies 13, but the same can be said for the interior bodies 13 stacked after the third one. In this manner, the plurality of interior bodies 13 are accommodated in the box 12 while being stacked while the plurality of ink cartridges 14 are placed sideways, and the upper surface of the box 12 is covered with the flaps 12d and 12e. By overlapping and changing the opening 12f of the box 12 from the open state to the closed state, the ink cartridge 14 can be transported.

In the above embodiment, the following effects can be obtained.
(1) The length La of the crease line portion 19 serving as the root portion of the load support piece 20 is greater than the case where the length La of the crease line portion 19 and the length Lb of the tip edge portion 20a of the load support piece 20 are the same. Is made shorter than the length Lb of the tip edge portion 20a, the size of the cutout hole 21 that causes a decrease in strength with respect to the load is reduced. Therefore, when the load support piece 20 that has been cut and raised receives a load, the base portion of the load support piece 20 falls below the base plate portion 16 so that a part of the edge of the cutout hole 21 hangs down. Is suppressed. Further, the load L can be stably supported in that the length Lb of the tip edge portion 20a serving as a support portion that receives a load in the load support piece 20 is longer than the length La of the crease line portion 19. become. Further, since the load support piece 20 is cut and raised from the substrate portion 16, the number of members does not increase. Therefore, the interior body 13 as a packing material is packed in a stacked state in the box 12 while placing a long ink cartridge 14 which is a long article on the substrate portion 16 without increasing the number of members. In this case, it is possible to suppress the ink cartridge 14 on the substrate unit 16 from being deformed due to the load.

  (2) The length La of the crease line portion 19 in the load support piece 20 is not more than a quarter of the entire length in the longitudinal direction in which the crease line portion 19 in the substrate portion 16 extends. Therefore, it is possible to restrict the size of the cutout hole 21 that the base portion of the load support piece 20 faces from being excessive, and the interior body 13 can ensure strength against the load.

  (3) The interior body 13 is provided with a plurality of load support pieces 20 on the same line along the longitudinal direction on the substrate portion 16, so that only one such load support piece 20 is provided on the substrate portion 16. The strength against the load can be improved.

  (4) The sum of the lengths La of the crease line portions 19 of the plurality of load support pieces 20 located on the same line along the longitudinal direction on the substrate portion 16 is the longitudinal direction in which the crease line portions 19 of the substrate portion 16 extend. It is 60% or less of the total length. Therefore, the interior body 13 can reduce the area ratio of the cutout holes 21 formed when the load support pieces 20 positioned on the same line as the entire board portion 16 are cut and raised. The strength against the load on the cut and raised substrate portion 16 can be ensured.

  (5) The total length Lb of the tip edge portion 20a of each load support piece 20 is 70% or more of the total length in the longitudinal direction in which the crease line portion 19 of the substrate portion 16 extends. Therefore, the interior body 13 can ensure a stable support function with respect to the load because the support portions that receive the load increase when the load support pieces 20 positioned on the same line as the entire substrate portion 16 are cut and raised. .

The above embodiment may be changed to another embodiment as described below.
In the embodiment, it is not necessary to provide a plurality of load support pieces 20 in the direction along the longitudinal direction of the substrate portion 16, and only one load support piece 20 may be provided. In this case, the longer the tip edge portion 20a of the load support piece 20 is, the more the region in contact with the lower surface 16b of the substrate portion 16 in the upper interior body 13 is. It is preferable to make it as long as possible. According to this, the work process for cutting up the load support piece 20 is reduced as compared to the case of cutting up the plurality of load support pieces 20, and the work efficiency of packing the ink cartridge 14 is improved.

  In the embodiment, the substrate unit 16 is provided with the load supporting pieces 20 arranged in two rows in the short direction of the substrate unit 16 with an interval for placing one ink cartridge 14 placed thereon. Not limited to this. For example, the load supporting pieces 20 are provided on the substrate unit 16 in a state where one or three or more rows are arranged in the short direction of the substrate unit 16, and two or four or more ink cartridges 14 are placed in a lying state. A possible interior body 13 may be configured.
