Description

  The present invention relates to a packing material for packing an object to be packed such as an air conditioner.

  For example, when a product having a certain weight, such as an air conditioner, is stored or transported, the product is packed with a packing material. Usually, this packing material is folded into a pair of shock-absorbing packing materials (for example, foamed polystyrene molded products) that are respectively fitted to both ends of the packaged object such as an air conditioner, and surrounds the packaged product. And a plate-shaped packing material (for example, corrugated cardboard) disposed across a pair of buffer packing materials.

  In the case of storage, transportation, etc., a packaged product in which the objects to be packed are packed with the packaging material is arranged with almost no gap in the horizontal direction and is also stacked and arranged in the height direction. Even in such a storage state and a transportation state, the object to be packed is protected from a load applied at the time of storage and transportation, an impact at the time of transportation, and the like by being packed with a packing material.

  For example, Patent Document 1 discloses a packing material for the purpose of further enhancing the function of protecting an object to be packed. In this packing material, a rising portion and a step whose thickness is reduced from the rising portion are provided on the entire outer periphery of the buffer packing material, and the outer surface of the plate-shaped packing material covering the step of the buffer packing material is buffered. It is said that damage to the plate-shaped packing material during transportation can be reduced by configuring the packing material so as not to protrude from the outer surface of the packing material.

Special table 2007-097359

  However, in the conventional packaging form such as Patent Document 1, the workability when arranging a plurality of packaged articles almost without gaps for storage, transportation, etc. is not necessarily good. In other words, when arranging multiple packages in the horizontal direction with almost no gap between adjacent packages, when inserting other packages between the packages, When inserting another packaged product, etc., it may be accompanied by an operation of inserting the packaged product into a narrow space, which may take time.

  Therefore, the present invention has been made in view of such a point, and an object of the present invention is to provide a packaging material excellent in workability when arranging a plurality of packages for storage, transportation, and the like. There is.

  The packing material of the present invention is for packing an object to be packed. The packing material is a pair of shock-absorbing packing materials (11) that can be fitted to both ends in a predetermined direction (D) of the packaged object, and is folded into a cylindrical shape, And a plate-shaped packing material (13) disposed across the pair of buffer packing materials (11).

  Each buffer packing material (11) includes a covering portion (19) covered by the plate-shaped packing material (13), and an outer end portion located outside the one direction (D) from the covering portion (19). (41).

  The outer end portion (41) is on the outer side in the orthogonal direction from the covering portion (19) on each side portion (44, 45) located on both sides in the orthogonal direction orthogonal to the one direction (D). It has a protruding part (46) protruding.

  Each convex part (46) has an inclined surface (46c) in which the protruding height from the covering part (19) increases toward the covering part (19) side in the one direction (D).

  The projecting height of the end portion on the covering portion (19) side of the inclined surface (46c) is equal to or greater than the thickness of the plate-shaped packing material (13) covering the covering portion (19).

  In this structure, each convex part (46) has the said inclined surface (46c). That is, since the outer end portion (41) of the buffer packing material (11) has a tapered shape in a plan view, in the operation of arranging a plurality of packing products almost without gaps for storage, transportation, etc. It becomes easy to insert the package into a narrow space. Thereby, the workability | operativity at the time of arranging a several package goods improves.

  Moreover, in this structure, the said protrusion height of the edge part by the side of the said coating | coated part (19) in the said inclined surface (46c) is more than the thickness of the said plate-shaped packing material (13) which coat | covers the said coating | coated part (19). Therefore, when arranging a plurality of packaged goods, it is suppressed that a plate-shaped packing material (13) contacts with an adjacent packaged product or a wall surface. Thereby, a deformation | transformation and damage with a plate-shaped packing material (13) can be suppressed. Moreover, since it is suppressed that the edge part of a plate-shaped packing material (13) catches on an adjacent packing goods, a wall surface, etc., the workability | operativity at the time of arranging a several packing goods improves more.

  Moreover, in this structure, since the said convex part (46) is provided, the impact which each convex part (46) applies to a packaged product from a horizontal direction (width direction) at the time of transportation etc. is effective. Since it also plays a role of absorbing, the function of protecting the packaged goods is excellent.

  Moreover, it is preferable that each convex part (46) is formed only in a part of height direction in the said side part (44,45).

  In this structure, each convex part (46) is formed not in the whole height direction of the said side part (44, 45) but in a part of height direction, Therefore A packaged article is inserted in a narrow space. In this case, the contact area with the next packaged item or the wall surface is reduced. Thereby, since the friction at the time of insertion is reduced, workability | operativity improves further. In addition, since the amount of use of the cushioning packing material (11) can be reduced as compared with the case where each convex portion (46) is formed in the entire height direction of the side portions (44, 45), the cost of material is reduced. This makes it possible to reduce costs.

  Moreover, it is preferable that each side part (44,45) has a continuous surface substantially continuous with the said coating | coated part (19).

  In this configuration, for example, an accessory such as a warranty card of the product is sandwiched in the gap between the covering portion (19) and the plate-shaped packing material (13), and only the end portion of the accessory is outside the gap, that is, the continuous surface. The accessory can be arranged in a state of being exposed at the position. As a result, even if the packaged item remains in a packed state, the accessory can be easily taken out by grasping and pulling the end of the accessory.

  The pair of cushioning packing materials (11) are arranged with a gap between each other, and the plate-shaped packing material (13) has a thickness of a portion covering the covering portion (19). It is preferable to be configured to be smaller than the thickness of the portion covering the gap.

  In this configuration, since the thickness of the portion covering the covering portion (19) is smaller than the thickness of the portion covering the gap between the buffer packing materials (11), the plate-shaped packing material covering the covering portion (19) The end of (13) becomes difficult to protrude outward. Thereby, since it is suppressed that the edge part of a plate-shaped packing material (13) catches on an adjacent packing goods, a wall surface, etc., the workability | operativity at the time of arranging a several packing goods further improves.

  The buffer packing material (11) is a molded product of foamed plastic, the plate-shaped packing material (13) is cardboard, and the covering portion (19) is perpendicular to the one direction (D). The plate-shaped packing material (13) has a quadrangular cross-section, and at least one corner portion on the outer periphery of the covering portion (19) is formed with a C surface extending along the one direction (D). Corresponds to each corner of the covering portion (19), and the position to be bent into the cylindrical shape is predetermined, and the covering portion (19) including the corner portion where the C surface is formed. The side surface is preferably configured such that the height thereof is larger than the inner dimension in the height direction of the plate-shaped packing material (13) facing the side surface.

  In this configuration, the height of the side surface of the covering portion (19) including the corner portion where the C surface is formed is the height of the plate-shaped packing material (13) facing the side portions (44, 45). It is larger than the inner dimension in the vertical direction. That is, since the inner dimension of the plate-shaped packing material (13) is smaller than the height of the side surface of the covering portion (19), the plate-shaped packing material (13) is tightly wound around the covering portion (19). It will be. At the time of winding, the corrugated board is gently bent along the C-plane at the folding position of the corrugated board corresponding to the C-plane while the foamed plastic is slightly deformed by the pressing force at the time of winding the cardboard. Thereby, since a covering part (19) is covered in the state where the corrugated cardboard was tightened, it can control that the swelling of a plate-shaped packing material (13) etc. arise in a packing state.

  The packaging material of the present invention is excellent in workability when arranging a plurality of packages for storage, transportation, and the like.

  Hereinafter, a packing material 10 according to an embodiment of the present invention will be described with reference to the drawings. The packing material 10 of this embodiment shown in FIG. 1 is for packing the indoor unit 91 (refer FIG. 8) of the air conditioner as a packaged article.

  The packing material 10 includes a pair of buffer packing materials 11 (right buffer packing material 11R, left buffer packing material 11L) and a plate-shaped packing material 13. The right shock-absorbing packing material 11 </ b> R is fitted to the right end 91 </ b> R (the front end in FIG. 1) of the indoor unit 91 in the longitudinal direction D, and the left shock-absorbing packing material 11 </ b> L is the longitudinal direction of the indoor unit 91. It is fitted to the left end 91L of D (the back end in FIG. 1). The plate-shaped packing material 13 is bent into a cylindrical shape and disposed so as to surround the indoor unit 91. In the present embodiment, the buffer packing material 11 is a molded product of foamed resin such as foamed polystyrene, and the plate-shaped packing material 13 is cardboard.

<Buffer packing material>
Since the right-side cushioning packing material 11R and the left-side cushioning packaging material 11L have substantially left-right symmetric shapes except for the shape of details, the structure of the right-side cushioning packaging material 11R will be mainly specifically described below. 2, FIG. 3 (A)-(C), FIG. 4 (A), (B) and FIG. In the following description, the right-side cushioning packaging material 11R is simply referred to as the cushioning packaging material 11 unless left and right identification is necessary.

  The buffer packing material 11 has a covering portion 19 and an outer end portion 41. The covering portion 19 and the outer end portion 41 are integrally formed. As shown in FIGS. 3B and 4A, the outer end 41 has a substantially rectangular outer shape when viewed from the front or the back. As shown in FIG. 3B, the covering portion 19 has a substantially rectangular outer shape when viewed from the back.

  The covering portion 19 is a portion covered with the plate-shaped packing material 13. The plate-shaped packing material 13 wound around the covering portion 19 whose outer shape in rear view is substantially rectangular has a cylindrical shape with a substantially rectangular cross section along the shape of the covering portion 19. The covering portion 19 includes an upper covering portion 19a positioned at the upper portion of the cylindrical shape, a lower covering portion 19b positioned at the lower portion, and both sides W1, W2 of the air conditioner 91 in the width direction (direction perpendicular to the longitudinal direction D) W. And a pair of side cover portions 19c and 19d (see FIG. 3B).

  As shown in FIGS. 3A and 3B, a recess 193 is formed in the upper covering portion 19a. The concave portion 193 is provided near the center in the width direction W in the upper covering portion 19a, and the concave dimension increases from the W2 side toward the W1 side. When the plate-shaped packing material 13 is wound around the covering portion 19, the upper covering portion 19a is covered with a second bent piece 52, which will be described later, and the end of the second bent piece 52 is disposed in the concave portion 193 of the upper covering portion 19a. Is done. The end of the second bent piece 52 disposed in the recess 193 is in a state of sinking below the second bent piece 52 that covers the other part of the upper covering portion 19a. In this case, the end portion of the first bent piece 51 is disposed on the end portion of the second bent piece 52 so as to be superimposed from above.

  As shown in FIGS. 3B, 5 </ b> A, and 5 </ b> B, the cushioning packing material 11 has a recess 111 that is fitted to the corresponding end 91 of the indoor unit 91. The inner surface of the recess 111 has an uneven shape that fits the outer surface of the end 91 of the indoor unit 91. The covering portion 19 extends in a cylindrical shape from the outer end portion 41 to the inner side D2 in the longitudinal direction D. The covering portion 19 covers a part of the side surface of the end portion 91R in the indoor unit 91.

  As shown in FIG. 3A, the outer end portion 41 is located on the outer side D <b> 1 in the longitudinal direction D with respect to the covering portion 19. As shown in FIG. 3B, the outer end portion 41 has an upper edge portion 42, a lower edge portion 43, a pair of side edge portions 44 and 45, and a front portion 50.

  The upper edge portion 42 forms the upper surface of the outer end portion 41, and the lower edge portion 43 forms the lower surface of the outer end portion 41. The pair of side edge portions 44 and 45 are located on both sides W1 and W2 in the width direction W, and form side surfaces on both sides of the outer end portion 41. The upper edge portion 42, the lower edge portion 43, and the pair of side edge portions 44 and 45 have a predetermined width in the longitudinal direction D. The front surface portion 50 is located further on the outer side D1 in the longitudinal direction D than the upper edge portion 42, the lower edge portion 43, and the pair of side edge portions 44 and 45.

  As shown in FIGS. 3 (B) and 4 (B), the upper edge portion 42 has a convex shape that protrudes upward from the upper covering portion 19a. The upper edge portion 42 has an upper surface 42a substantially parallel to the horizontal direction, and an inner side extending obliquely downward from the edge of the upper surface 42a on the inner side D2 (on the upper covering portion 19a side) in the longitudinal direction D toward the upper covering portion 19a. It has the inclined surface 42b and the outer inclined surface 42c extended diagonally downward toward the front part 50 from the edge of the outer side D1 of the longitudinal direction D in the upper surface 42a.

  The lower edge portion 43 has a convex shape that protrudes substantially below the lower covering portion 19b. The lower edge portion 42 has a lower surface 43a that is substantially parallel to the horizontal direction, and an inclination that extends obliquely upward from the edge of the lower surface 43a on the inner side D2 (on the lower coating portion 19b side) in the longitudinal direction D toward the lower coating portion 19b. It has the surface 43b and the inclined surface 43c extended diagonally upward toward the front part 50 from the edge of the outer side D1 of the lower surface 43a in the longitudinal direction D.

  The protruding height of the upper edge portion 42 from the upper covering portion 19a and the protruding height of the lower edge portion 43 from the lower covering portion 19b are determined by the plates covered by these covering portions 19a and 19b. It is set to be equal to or greater than the thickness of the packing material 13. Thereby, in the state in which the indoor unit 91 is packed, the plate-shaped packing material 13 is suppressed from protruding above the upper edge portion 42, and the plate-shaped packing material 13 protrudes below the lower edge portion 43 in the same manner. It is suppressed.

  In addition, the predetermined width of the upper edge portion 42 and the lower edge portion 43 receives the weight from above at the upper edge portion 42 and the lower edge portion 43 when the packaged products are stacked in the height direction. It is set to a size that can withstand the weight. As a result, the upper edge portion 42 and the lower edge portion 43 can stably support the packaged products stacked on the upper edge portion 42 and the lower edge portion 43. In addition, since the stacked packages are in contact with the upper edge portion 42 and the lower edge portion 43, the load applied to the plate-shaped packing material 13 can be reduced, and the stacked packages and the plate-shaped packing material 13 are in contact with each other. Can also be suppressed.

  The side edge portion 44 is provided with a convex portion 46 projecting outward from the side portion covering portion 19c. The convex portion 46 is not formed in the entire height direction at the side edge portion 44 but is provided only in a part of the height direction. Specifically, the convex portion 46 is provided near the center in the height direction at the side edge portion 44. Further, the side edge portion 44 has continuous surfaces 47 and 48 that are continuous with the side portion covering portion 19 c almost without any step in a region above the convex portion 46 and a region below the convex portion 46.

  The convex portion 46 has a side surface 46a substantially parallel to the vertical direction, and inclined surfaces 46b to 46e positioned around the side surface 46a. The inner inclined surface 46b extends in an oblique direction with respect to the longitudinal direction D from the edge of the side surface 46a on the inner side D2 (side covering portion 19c side) in the longitudinal direction D toward the side covering portion 19c.

  The outer inclined surface 46c extends obliquely with respect to the longitudinal direction D from the edge of the outer side D1 in the longitudinal direction D on the side surface 46a toward the front face 50. In other words, the outer inclined surface 46c has a shape in which the protruding height from the covering portion 19 increases toward the inner side D2 in the longitudinal direction D.

  The edge S located on the inner side D2 in the longitudinal direction D on the inclined surface 46c, that is, the edge S located on the outer side D1 in the longitudinal direction D on the side surface 46a has a protruding height that covers the side covering portion 19c. It is set to be equal to or greater than the thickness of the packing material 13. The protruding height here means a dimension protruding in the width direction W in the width direction W when the position of the side covering portion 19c is set as a reference (zero).

  The upper inclined surface 46d extends in an oblique direction from the upper edge of the side surface 46a toward the continuous surface 47. The lower inclined surface 46e extends obliquely from the lower end side of the side surface 46a toward the continuous surface 48.

  The front part 50 has a rectangular end surface 50a substantially perpendicular to the longitudinal direction D, and inclined surfaces 50b to 50e positioned around the end surface 50a. The end face 50a is provided with a grip portion 95 that grips the packaged product when the operator carries the packaged product.

  The inclined surface 50b positioned on the upper side of the end surface 50a extends obliquely upward from the end side 511 on the upper side of the end surface 50a toward the upper edge portion 42. The inclined surface 50b is continuous with the outer inclined surface 42c of the upper edge portion 42 with almost no step. That is, the outer inclined surface 42 c and the inclined surface 50 b constitute an upper inclined surface of the outer end portion 41.

  The inclined surface 50c positioned on the lower side of the end surface 50a extends obliquely downward from the lower side edge 512 of the end surface 50a toward the lower edge portion 43. The inclined surface 50c is continuous with the outer inclined surface 43c of the lower edge portion 43 with almost no step. That is, the outer inclined surface 43 c and the inclined surface 50 c constitute a lower inclined surface of the outer end portion 41.

  The inclined surface 50d on the width direction W1 side of the front portion 50 extends obliquely with respect to the longitudinal direction D from the end side 513 on the width direction W1 side of the end surface 50a toward the side edge portion 44. The inclined surface 50d is continuous with the outer inclined surface 46c of the convex portion 46 at the side edge portion 44 with almost no step. That is, the outer inclined surface 46 c and the inclined surface 50 d constitute one side inclined surface of the outer end portion 41.

  Similarly, the inclined surface 50e on the width direction W2 side of the front surface portion 50 extends obliquely with respect to the longitudinal direction D from the end side 514 on the width direction W2 side of the end surface 50a toward the side edge portion 45. The inclined surface 50e is continuous with the outer inclined surface 46c of the convex portion 46 at the side edge 45 with almost no step. That is, the outer inclined surface 46 c and the inclined surface 50 e constitute the other side inclined surface of the outer end portion 41.

  As shown in FIGS. 4A and 4B, the portion on the direction D1 side of the outer end portion 41 has a shape that tapers toward the direction D1. Moreover, in the outer end portion 41 of the present embodiment, the substantially rectangular shape formed by the end sides 511 to 514 of the end surface 50a is smaller than the substantially rectangular shape formed by the outer surfaces of the covering portions 19a to 19d in the front view. Designed to be Thereby, it is possible to increase the degree of taper of the outer end 41. This feature will be specifically described as follows. That is, the upper side edge 511 of the end surface 50a in the front portion 50 is positioned below the upper surface of the upper covering portion 19a in the height direction. The lower side edge 512 of the end surface 50a is located above the lower surface of the lower covering portion 19b in the height direction. The end side 513 on the width direction W1 side of the end surface 50a is located in the width direction W2 side in the width direction W with respect to the outer surface of the side cover portion 19c. The end side 514 on the width direction W2 side of the end surface 50a is located in the width direction W1 side with respect to the outer side surface of the side cover portion 19d in the width direction W.

  As shown in FIGS. 3 (B) and 4 (B), the covering portion 19 has a C surface 191 extending along the longitudinal direction D formed at the upper corners K1, K2 on the outer periphery thereof. Yes. As shown in FIGS. 3A, 3B, and 4B, each C surface 191 is inclined with respect to the upper surface of the upper covering portion 19a and the outer surfaces of the side covering portions 19c, 19d. It is. The C surface 191 may also be provided at two corners at the lower part of the covering portion 19. The function of the C surface 191 will be described later.

  The pair of cushioning packing materials 11 are arranged with a gap between each other. The plate-shaped packing material 13 is arrange | positioned so that this clearance gap may be covered.

<Plate-shaped packing material>
As shown in FIG. 1, the plate-shaped packing material 13 is bent into a cylindrical shape including a top surface portion 31, a bottom surface portion 32, and a pair of side surface portions 33 and 34. The plate-shaped packing material 13 is disposed across the covering portion 19 of the pair of buffer packing materials 11. The plate-shaped packing material 13 has circumferential ends that are abutted or overlapped at the top surface portion 31 and surrounds the indoor unit 91.

  The top surface portion 31 is bent at a first bent piece 51 that is bent at a corner portion K11 located on one side W1 in the width direction W orthogonal to the longitudinal direction D, and at a corner portion K12 that is located on the other side W2 in the width direction. And two folded pieces 52.

  The plate-shaped packing material 13 has an approximate folding position determined in advance so that it can be easily bent at positions corresponding to the corners of the covering portion 19. Specifically, for example, a crease is provided in advance at the approximate folding position.

  As described above, in the outer edge portion 41, the upper edge portion 42 is set such that the protruding height from the covering portion 19a is equal to or greater than the thickness of the plate-shaped packing material 13 that covers the covering portion 19a. In the lower edge portion 43, the protruding height from the covering portion 19b is set to be equal to or greater than the thickness of the plate-shaped packing material 13 that covers the covering portion 19b. The projecting height of the edge S located on the inner side D2 in the longitudinal direction D of each inclined surface 46c is set to be equal to or greater than the thickness of the plate-shaped packing material 13 that covers the side covering portion 19c. In the present embodiment, as shown in FIG. 6, in order to increase the difference between each protruding height and the thickness of the plate-shaped packing material 13, the thickness of the portion covering the covering portion 19 in the plate-shaped packing material 13. t1 is made smaller than the thickness t2 of other parts (parts covering the gaps between the buffer packing materials 11).

  Thus, in order to make the thickness different for each part in the plate-shaped packing material 13, the thickness of the core that forms the wave-shaped portion of the plate-shaped packing material (corrugated cardboard) 13 may be made different for each part, After the entire plate-shaped packing material 13 is formed with the same thickness, the thickness of the plate-shaped packing material 13 may be reduced to be smaller than that of the other portions by, for example, pressing a portion to reduce the thickness.

  In the present embodiment, the side surfaces of the side covering portions 19c and 19d including the corner portion where the C surface 191 is formed are in the height direction of the plate-shaped packing material 13 whose height H1 faces each side surface. It is designed to be larger than the inner dimension H2. As a result, the plate-shaped packing material 13 is tightly wound around the covering portion 19. At the time of winding, at the folding position of the corrugated cardboard corresponding to the C surface 191, the foamed plastic constituting the cushioning packing material 11 is slightly deformed by the pressing force at the time of corrugated cardboard winding, and the plate-shaped packing material (corrugated cardboard) 13 It is gently bent along the surface 191. Therefore, since the plate-shaped packing material 13 is covered with the covering portion 19 in a tensioned state, it is possible to suppress the occurrence of blistering of the plate-shaped packing material 13 in the packing state.

  The degree to which the height H1 is made larger than the inner dimension H2 is not particularly limited, but a specific example is as follows. For example, as shown in FIG. 7, when the lower end 192 of the side covering portion 19 d and the lower end 131 of the inner side surface of the plate-shaped packing material 13 are aligned in the height direction and compared (state shown in FIG. 7). A form in which the upper end 132 of the inner side surface of the plate-shaped packing material 13 is located within the range R of the C surface 191 in the height direction can be exemplified. Thereby, when the plate-shaped packing material 13 is wound around the covering portion 19, a more appropriate tension of the plate-shaped packing material 13 is obtained.

<Packing procedure>
In the present embodiment, the packing operation of the indoor unit 91 is performed using the packing material 10 in the following procedure. First, as shown in FIGS. 8A and 8B, the buffer packing materials 11R and 11L are fitted into the end portions 91R and 91L in the longitudinal direction D of the indoor unit 91, respectively. In this state, as shown in FIG. 8B, the pair of buffer packing materials 11R and 11L fitted to the end portions 91R and 91L of the indoor unit 91 are separated from each other. Therefore, portions other than both end portions 91 </ b> R and 91 </ b> L of the outdoor unit 91 are not covered with the cushioning packing material 11.

  Next, the unfolded unfolded plate-shaped packing material 13 is disposed under the buffer packing material 11 and the indoor unit 91, and is bent into a cylindrical shape so as to surround the periphery of the indoor unit 91 (FIG. 8C). reference). In this state, the plate-shaped packing material 11 is disposed so as to straddle between the covering portion 19 of the right-side cushioning packing material 11 </ b> R and the covering portion 19 of the left-side buffering packing material 11 </ b> L, and covers these covering portions 19.

  Further, both end portions of the plate-shaped packing material 13, that is, the end portions of the first bent pieces 51 and the end portions of the second bent pieces 52 are abutted or overlapped with each other at the top surface portion 31. These ends are joined to each other using, for example, an adhesive tape. Thereby, a packaged product is completed. In addition, as shown in FIG. 1, you may further bind a packaged product using the strip | belt band 93 made from resin etc. as needed.

<Modification>
FIG. 9 (A) is a front view showing Modification 1 of the cushioning packing material 11 in the packing material according to the embodiment, FIG. 9 (B) is a side view thereof, and FIG. It is the top view to which the periphery of the convex part 46 provided in the side edge part 44 of the buffer packing material 11 was expanded, FIG.9 (D) is the IXD-IXD sectional view taken on the line of FIG. 9 (A).

  As shown in FIGS. 9A and 9D, the cushioning packing material 11 includes two recesses 97 formed from the upper surface of the upper edge portion 42 to the front surface 50a, and the lower surface of the lower edge portion 43 to the front surface 50a. And two formed recesses 97. In these recesses 97, resin-made band-like bands 93 as shown in FIG. Thereby, it can control that beltlike band 93 shifts in the width direction W.

  Moreover, in this modification 1, the shape of the convex part 46 each provided in the side edge parts 44 and 45 differs from the form mentioned above. Each convex part 46 of this modification 1 has a substantially triangular shape in plan view as shown in FIG.

  Each convex part 46 has the inclined surface 46c from which the protrusion height from the side part covering part 19c becomes large as it goes to the D1 side (side part covering part 19c side) of the longitudinal direction D. The protruding height of the edge S on the D1 side on the inclined surface 46c is equal to or greater than the thickness of the plate-shaped packing material 13 that covers the side covering portion 19c. Each convex portion 46 has a surface 46f extending from the end side S toward the side portion covering portion 19c. The angle formed by the surface 46f and the side covering portion 19c is substantially a right angle.

  FIG. 10 is a side view showing Modification Example 2 of the buffer packing material 11 in the packing material according to the present embodiment. In the shock-absorbing packing material 11 according to the second modification, the side edge portions 44 and 45 are continuous with the side covering portion 19c in a region above the convex portion 46 and a region below the convex portion 46 with almost no step. In addition to the continuous surfaces 47 and 48, the region 46 on the direction D <b> 2 side of the convex portion 46 has a continuous surface 49 that is continuous with the side covering portion 19 c almost without a step.

  As described above, in the present embodiment, the outer end portion 41 of the shock-absorbing packing material 11 has a tapered shape in plan view. In the work of arranging, it becomes easy to insert the package into a narrow space. Thereby, the workability | operativity at the time of arranging a several package goods improves.

  Moreover, in this embodiment, since the protrusion height of the edge part by the side of the coating | coated part 19 in the inclined surface 46c is more than the thickness of the plate-shaped packing material 13 which coat | covers the coating | coated part 19, when arranging several packaged goods In addition, the plate-shaped packing material 13 is prevented from coming into contact with the adjacent packing product or wall surface. Thereby, it can suppress that the plate-shaped packing material 13 is damaged. Moreover, since it is suppressed that the edge part of the plate-shaped packing material 13 catches on an adjacent packing goods, a wall surface, etc., the workability | operativity at the time of arranging a several packing goods improves more.

  Moreover, in this embodiment, since each convex part 46 also plays the role which absorbs the impact added from a horizontal direction (width direction) with respect to a packaged item at the time of transport etc., the function which protects a to-be-packaged item is carried out. Are better.

  Moreover, in this embodiment, since each convex part 46 is formed only in one part of the height direction in the side edge parts 44 and 45, when inserting a packing goods into a narrow space, an adjacent packing goods and wall surface The contact area with is reduced. Thereby, since the friction at the time of insertion is reduced, workability | operativity improves further. In addition, since the amount of use of the cushioning packing material 11 can be reduced as compared with the case where each convex portion 46 is formed in the entire height direction of the side edge portions 44 and 45, the cost can be reduced in terms of material costs. Become.

  Further, in the present embodiment, each side edge portion 44, 45 has a continuous surface that is substantially continuous with the covering portion 19. Therefore, for example, an accessory such as a warranty card for the product is attached to the covering portion 19 and the plate-shaped packing material 13. The accessory can be arranged in a state where only the end of the accessory is exposed to the outside of the gap, that is, the position of the continuous surface. As a result, even if the packaged item remains in a packed state, the accessory can be easily taken out by grasping and pulling the end of the accessory.

  Moreover, in this embodiment, since the thickness of the site | part which coat | covers the coating | coated part 19 is smaller than the thickness of the site | part which covers the said clearance gap between buffer packing materials 11, the edge of the plate-shaped packing material 13 which coat | covers the coating | coated part 19 The part is difficult to protrude outward. Thereby, since it is suppressed that the edge part of the plate-shaped packing material 13 catches on an adjacent packing goods, a wall surface, etc., the workability | operativity at the time of arranging a several packing goods further improves.

  Further, in the present embodiment, the height of the side surface of the covering portion 19 including the corner portion on which the C surface is formed is the inner height of the plate-shaped packing material 13 facing the side edge portions 44 and 45. It is bigger than the size. That is, since the inner dimension of the plate-shaped packing material 13 is smaller than the height of the side surface of the covering portion 19, the plate-shaped packing material 13 is tightly wound around the covering portion 19. At the time of winding, at the folding position of the plate-shaped packing material (corrugated cardboard) 13 corresponding to the C surface 191, the foamed plastic constituting the buffer packing material 11 is slightly deformed by the pressing force at the time of winding the cardboard, so that the plate-shaped packing is formed. The material 13 is gently bent along the C surface 191. Thereby, since the plate-shaped packing material 13 is covered with the covering portion 19 in a tight state, it is possible to suppress the occurrence of blistering of the plate-shaped packing material 13 in the packed state.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and improvements can be made without departing from the spirit of the present invention.

  For example, in the above-described embodiment, the case where the buffer packing material 11 is a molded product of foamed resin such as foamed polystyrene and the plate-shaped packing material 13 is corrugated cardboard is described as an example, but the present invention is not limited to this. As the buffer packing material 11 and the plate-shaped packing material 13, other packing materials can be adopted as long as they have the same functions as the foamed resin molded product and the cardboard.

  Moreover, although the said embodiment gave and demonstrated the case where a pair of buffer packing material 11 was fitted by the both ends of the longitudinal direction D of a to-be-packaged item, it is not limited to this. The pair of shock-absorbing packing materials 11 may be fitted to both ends in the width direction orthogonal to the longitudinal direction of the article to be packed.

  Moreover, in the said embodiment, although the upper edge part 42 and the lower edge part 43 have the shape which protrudes substantially rather than the coating | coated part 19, it is not limited to this. For example, the upper edge portion 42 and the lower edge portion 43 may have a partially formed convex portion, such as the convex portion 46 of the side edge portions 44 and 45.
