Description

Technical Field

[0001] The present invention relates to a packaging material used for supporting and packing an outdoor unit of a split air conditioner and the like.

Background Art

[0002] Conventionally, in order to prevent damage such as scratches and dents on products from vibration and impact during transportation in distribution and storage in a warehouse, at the time of factory shipment, the entire surface of the product or the upper surface of the top plate and the bottom surface of the bottom plate are protected by a packaging material made of styrofoam or cardboard. (For example, Patent Document 1)

[0003] On the other hand, styrofoam does not decompose naturally, and when discarded in rivers or the sea, it becomes microplastics after long-term drifting, and there are problems such as marine organisms accidentally ingesting it and dying.

[0004] Therefore, as in Patent Document 2, it has been devised to use laminated cardboard as a packaging material instead of styrofoam.

[0016] Similarly, the left rear leg portion 22 has standing portions 22a that hang downward at both left and right ends in the left - right direction of a flat portion 22b that contacts the bottom plate 11. The standing portions 22a include left standing portions 22a1 and right standing portions 22a2 at both left and right ends in the left - right direction of the left rear leg portion 22, and outer standing portions 22a3 in the outer direction of the object to be packaged 10. A locking portion 20d for fixing the outdoor unit 10a extends horizontally outward from the lower end of the outer standing portion 22a3. Similarly, the right front leg portion 23 has standing portions 23a that hang downward at both left and right ends in the left - right direction of a flat portion 23b that contacts the bottom plate 11. The standing portions 23a include left standing portions 23a1 and right standing portions 23a2 at both left and right ends in the left - right direction of the right front leg portion 23, and outer standing portions 23a3 in the outer direction of the object to be packaged 10. A locking portion 20d for fixing the outdoor unit 10a extends horizontally outward from the lower end of the outer standing portion 23a3. Similarly, the right rear leg portion 24 has standing portions 24a that hang downward at both left and right ends in the left - right direction of a flat portion 24b that contacts the bottom plate 11. The standing portions 24a include left standing portions 24a1 and right standing portions 24a2 at both left and right ends in the left - right direction of the right rear leg portion 24, and outer standing portions 24a3 in the outer direction of the object to be packaged 10. A locking portion 20d for fixing the outdoor unit 10a extends horizontally outward from the lower end of the outer standing portion 22a3.

[0017] As shown in FIG. 1, the packaging material 1 includes a pair of lower packaging materials 30 that support the leg portions 20 below the object to be packaged 10, and a pair of upper packaging materials 40 that package the top plate 12 above the object to be packaged 10. The lower packaging materials 30 include a left - hand lower packaging material 31 and a right - hand lower packaging material 32, and the upper packaging materials 40 include a left - hand upper packaging material 41 and a right - hand upper packaging material 42. Furthermore, the packaging material 1 includes a lower bottom box portion 50 that houses the left - hand lower packaging material 31 and the right - hand lower packaging material 32 at the left - right corners, and an upper lid portion 51 that houses the left - hand upper packaging material 41 and the right - hand upper packaging material 42 at the left - right corners. The lower bottom box portion 50 is a bottomed box - shaped packaging member that protects the bottom surface of the object to be packaged 10 and is open upward, and the upper lid portion 51 is a lid - shaped packaging member that protects the upper surface of the object to be packaged and forms a pair with the lower bottom box portion 50 and is open downward.

[0018] Here, the lower packaging material 30, the upper packaging material 40, the lower bottom box section 50, and the upper lid section 51 are made of corrugated cardboard. The lower packaging material 30 and the upper packaging material 40 are formed by stacking two types of laminated cardboard, which are made by bonding multiple corrugated cardboard sheets of the same shape together with adhesive and stacking them vertically.

[0019] The laminated structure can be either a vertical lamination method, where the cardboard cores are stacked in the same direction, or a cross-lamination method, where they are stacked in alternating directions.

[0020] The shapes of the left lower packaging material 31 and the right lower packaging material 32 will be explained based on Figures 3 to 9.

[0021] Let me explain the shape of the lower left packaging material 31. The left lower packaging material 31 has a contact portion 31a1 on the right front side of the top surface portion 31a of the left lower packaging material 31, which is in contact with the flat portion 21b of the left front leg portion 21. The left, right, and front sides of the contact portion 31a1 have notches 31b that avoid the left upright portion 21a1, the right upright portion 21a2, and the outer upright portion 21a3, and the rear side of the notches 31b has a wall surface 31e1. Furthermore, the lower left packaging material 31 has a contact portion 31a2 on the right rear side of the top surface portion 31a, which the flat portion 21b of the left rear leg portion 22 abuts against. On the left, right, and rear sides of the contact portion 31a2, there are notches 31c that avoid the left upright portion 22a1, the right upright portion 22a2, and the outer upright portion 22a3, independently of the aforementioned notches 31b, and the front side of the notches 31c has a wall surface 31e2. Furthermore, the lower left packaging material 31 has a U-shaped slit 31d on the left side of the top surface 31a, consisting of a front slit 31d1, a side slit 31d2, and a rear slit 31d3. The slit 31d is provided at a position where the left, right, front, and rear side plates 13 of the packaged item 10 are projected vertically onto the top surface 31a.

[0022] The lower left packaging material 31 is made by laminating corrugated cardboard sheets 31f1, 31f2, 31f3, 31f4, and 31f5, each having a notch 31b, by bonding them together with adhesive, and laminating corrugated cardboard sheets 31f6 and 31f7, which do not have a notch 31b or a slit 31d, by bonding them together with adhesive, and then forming a slit 31d in the sheets 31f1, 31f2, 31f3, 31f4, and 31f5.

[0023] Let's describe the shape of the lower right-side packaging material 32. The right lower packaging material 32 has a contact portion 32a1 on the left front side of the top surface 32a of the right lower packaging material 32, which is in contact with the flat portion 23b of the right front leg 23. The left, right, and front sides of the contact portion 32a1 have notches 32b that avoid the left upright portion 23a1, the right upright portion 23a2, and the outer upright portion 23a3, and the rear side of the notches 32b has a wall surface 32e1. Furthermore, the lower right packaging material 32 has a contact portion 32a2 on the left rear side of the top surface portion 32a, which the flat portion 24b of the right rear leg portion 24 abuts against. On the left, right, and rear sides of the contact portion 32a2, there are notches 32c that avoid the left upright portion 24a1, the right upright portion 24a2, and the outer upright portion 24a3, independently of the aforementioned notches 32b, and the front side of the notches 32c has a wall surface 32e2. Furthermore, the lower right-side packaging material 32 has a U-shaped slit 32d on the right side of the top surface 32a, consisting of a front slit 32d1, a side slit 32d2, and a rear slit 32d3. The slit 32d is located at a position where the side plates 13 of the packaged item 10 in the left, right, front, and rear directions are projected vertically onto the top surface 32a.

[0024] The lower right packaging material 32 is made by laminating corrugated cardboard sheets 32f1, 32f2, 32f3, 32f4, and 32f5, each having a notch 32b, by bonding them together with adhesive, and laminating corrugated cardboard sheets 32f6 and 32f7, which do not have a notch 32b or a slit 32d, by bonding them together with adhesive, and then forming a slit 32d in the sheets 32f1, 32f2, 32f3, 32f4, and 32f5.

[0025] The procedure for packaging the item to be packaged 10 into the packaging material 1 will be explained below.

[0026] As shown in Figure 1, the left lower packaging material 31 and the right lower packaging material 32 formed as described above are placed in the left-right corners of the lower bottom box section 50. Then, the packaged item 10, such as the outdoor unit 10a, is placed on top of the lower left packaging material 31, with the flat part 21b resting on the contact part 31a1 and the flat part 22b resting on the contact part 31a2, and the side plate 13 is aligned with the slit 31d in a plan view. Similarly, the packaged item 10, such as the outdoor unit 10a, is placed on the lower right packaging material 32, with the flat portion 23b resting on the contact portion 32a1 and the flat portion 24b resting on the contact portion 32a2, and the side plate 13 is aligned with the slit 32d in a plan view. Next, the upper lid 51 is placed over the packaged item 10, and the left upper packaging material 41 and the right upper packaging material 42 are placed through the opening at the top of the upper lid 51 so as to be contained in the left and right corners of the upper lid 51. After closing the flap 51a of the upper lid 51, the lower bottom box 50 and the upper lid 51 are fastened together with a cable tie (not shown).

[0027] In this way, the packaged item 10 and the left lower packaging material 31 are in contact with the left front leg portion 21b, which is in contact with the contact portion 31a1 of the left lower packaging material 31, and the left rear leg portion 22b, which is in contact with the contact portion 31a2 of the left lower packaging material 31. The left and right sides of the flat portion 21b, as well as the left upright portion 21a1, right upright portion 21a2, and outer upright portion 21a3, are not in contact with the left lower packaging material 31 due to the notch portion 31b, and the left and right sides of the flat portion 22b, as well as the left upright portion 22a1, right upright portion 22a2, and outer upright portion 22a3, are not in contact with the left lower packaging material 31 due to the notch portion 31c. Furthermore, the lower left packaging material 31 is packaged without coming into contact with other external components of the packaged item 10.

[0028] Similarly, the packaged item 10 and the right lower packaging material 32 are in contact with the right front leg portion 23b, which is in contact with the abutment portion 32a1 of the right lower packaging material 32, and the right rear leg portion 24b, which is in contact with the abutment portion 32a2 of the right lower packaging material 32. The left and right sides of the flat portion 23b, as well as the left upright portion 23a1, right upright portion 23a2, and outer upright portion 23a3, are not in contact with the right lower packaging material 32 due to the notch portion 32b. The left and right sides of the flat portion 24b, as well as the left upright portion 24a1, right upright portion 24a2, and outer upright portion 24a3, are not in contact with the right lower packaging material 32 due to the notch portion 32c. Furthermore, the lower right-side packaging material 32 is packaged without coming into contact with other external components of the packaged item 10.

[0029] With this type of packaging material 1, in response to vibrations in the left-right direction during packaging, notches 31b are provided on the left and right sides of the contact portion 31a1 to avoid the left upright portion 21a1 and the right upright portion 21a2. As a result, the left front leg portion 21 is constrained to move in the left-right direction by the notches 31b and the left upright portion 21a1 and the right upright portion 21a2. Similarly, the left rear leg 22, right front leg 23, and right rear leg 24 can also suppress the movement of the packaged object 10 in the left-right direction, thereby suppressing damage to the packaged object 10.

[0030] Furthermore, the action of the left lower packaging material 31 against vibrations in the front-to-back direction during packaging will be explained. As described above, the left front leg portion 21 has a raised portion 21a, the left rear leg portion 22 has a raised portion 22a, and the left lower packaging material 31 has a notch portion 31b to avoid the raised portion 21a and a notch portion 31c to avoid the raised portion 22a, and between the raised portion 21a and the raised portion 22a, there is a wall surface 31e1 facing forward and a wall surface 31e2 facing backward, which are formed by the notches 31b and 31c. As a result, the vertical portion 21a abuts against the wall surface 31e1 in response to vibrations to the rear, thereby suppressing the movement of the packaged item 10, and the vertical portion 22a abuts against the wall surface 31e2 in response to vibrations to the front, thereby suppressing the movement of the packaged item 10.

[0031] Similarly, the lower right-side packaging material 32 will be described. As described above, the right front leg portion 23 has a protruding portion 23a, the right rear leg portion 24 has a protruding portion 24a, and the right lower packaging material 32 has a notch portion 32b to avoid the protruding portion 23a and a notch portion 32c to avoid the protruding portion 24a, and between the protruding portion 23a and the protruding portion 24a, there is a wall surface 32e1 facing forward and a wall surface 32e2 facing backward, which are formed by the notches 32b and 32c. As a result, the vertical portion 23a abuts against the wall surface 32e1 in response to vibrations to the rear, thereby suppressing the movement of the packaged item 10, and the vertical portion 24a abuts against the wall surface 32e2 in response to vibrations to the front, thereby suppressing the movement of the packaged item 10.

[0032] Furthermore, in the event of a downward impact during packaging, the contact portions 31a1, 31a2, 32a1, and 32a2 of the lower packaging material 30 support the sinking of the flat portions 21b, 22b, 23b, and 24b of the packaged item 10, and the top surface 31a of the left lower packaging material 31 and the top surface 32a of the right lower packaging material 32 support the sinking of the bottom plate 11, thereby mitigating the impact on the packaged item 10.

[0033] Furthermore, in the event of a relatively strong downward impact during packaging, such as dropping, a U-shaped slit 31d consisting of a front slit 31d1, a side slit 31d2, and a rear slit 31d3 is provided on the left side of the top surface 31a of the left lower packaging material 31, and a U-shaped slit 32d consisting of a front slit 32d1, a side slit 32d2, and a rear slit 32d3 is provided on the right side of the top surface 32a of the right lower packaging material 32. As a result, the top surfaces 31a and 32a on the lower side of the packaged item 10 sink in with the impact, with the boundary between these slits 31d and 32d, thereby mitigating the impact on the bottom plate 11 and side plates 13 of the packaged item 10 and reducing the deformation of the bottom plate 11 and side plates 13.

[0034] Furthermore, the slits 31d and 32d serve as a guide for positioning the packaged item 10 when it is placed in the lower packaging material 30.

[0035] As described above, with the configuration of the packaging material 1 of the present invention, the use of corrugated cardboard material for the packaging material 1 is environmentally friendly, and since the external components of the packaged item 10 do not interfere with the lower packaging material 30, damage to the packaged item 10 from impacts in the front, back, left, right, up, and down directions can be suppressed.

[0036] Note that the slit 31d may be at least one of the front slit 31d1, the side slit 31d2, and the rear slit 31d3. Similarly, the slit 32d may be at least one of the front slit 32d1, the side slit 32d2, and the rear slit 32d3.

[0037] The other configurations used in this embodiment are presented as examples only and are not intended to limit the scope of the invention. It can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their variations are included in the scope and spirit of the invention, as well as in the claims of the invention and its equivalents.

[0038] For example, although the packaged object 10 according to the present invention was described using the outdoor unit 10a of a split air conditioner with a hot water heating function, it can also be applied to outdoor units of split air conditioners and heat pump units of natural refrigerant water heaters, in addition to the outdoor unit 10a of a split air conditioner with a hot water heating function.
