Description

[Technical field]

[0001] The present invention relates to a packaging structure for a water heater having a rectangular parallelepiped outer shape, and more particularly to a packaging structure for a water heater placed on a pallet member larger than the bottom surface of the water heater for transportation. [Background technology]

[0002] Typically, a hot water device manufactured in a factory and shipped is placed on a pallet member so that it can be transported by a forklift. In order to prevent the hot water device from being soiled, scratched, or damaged due to collision with other objects, the hot water device is covered with a packaging material made of, for example, cardboard, and the outer periphery of the packaging material is fixed with a band together with the pallet member to be integrated. When the pallet member on which the packaged hot water device is placed is lifted with a forklift, a pallet member larger than the bottom surface of the hot water device is used so that the packaging material will not be soiled or damaged by the forklift coming into contact with the packaging material.

[0003] The hot water devices to be shipped are loaded onto a transport vehicle so that no gaps are formed between the pallet members. At this time, since the pallet members are larger than the bottom surfaces of the hot water devices, there are gaps between the hot water devices, and the hot water devices may swing due to the swinging of the transport vehicle during transport. If the hot water devices swing, there is a risk that adjacent hot water devices will collide with each other, and there is also a risk that the hot water devices will tip over. For this reason, as in Patent Document 1, for example, a spacer member is placed over the packaging material on the top of the hot water devices and fixed with a band, and a gap is prevented from being formed between the packaging material of the hot water devices adjacent in the direction in which they tend to swing, making it difficult for the hot water devices to swing and preventing damage and tipping over.

[0004] [Patent Document 1] Patent No. 5858213 Summary of the Invention [Problem to be solved by the invention]

[0005] The spacer member in Patent Document 1 is formed integrally with the top plate so that two cushioning functional parts face each other, and the two cushioning functional parts cover the packaging material on the top of the hot water device so as to sandwich the sides of the packaging material. However, because the top plate part connecting the two cushioning functional parts is large, a lot of material is required to form the spacer member, which increases the manufacturing cost of the packaging material for the hot water device.

[0006] An object of the present invention is to provide a packaging structure for a hot water device that can conserve materials and reduce manufacturing costs while maintaining the function of suppressing shaking during transportation. [Means for solving the problem]

[0007] The packaging structure for a hot water device according to the invention of claim 1 comprises a pallet member for placing a hot water device having an external shape of a rectangular parallelepiped, and a top member formed in a box shape with an open bottom for covering an upper portion of the hot water device, the packaging structure for the hot water device further comprising spacer mounting portions provided on side plate portions extending downward from opposing long sides of a top plate portion of the top member, and a spacer mounting portion provided on the spacer mounting portions. The outer lateral side of the top member Insert it from the Ta Equipped with a spacer member for cushioning The spacer mounting portion is provided at the upper center of the side plate portion in the width direction, and the spacer mounting portion has a first horizontally elongated through hole and a second horizontally elongated through hole shorter than the first through hole at a position spaced a predetermined distance downward from the first through hole, and the spacer member is mounted so as to protrude outward from the side plate portion. It is characterized by the following.

[0008] According to the above-mentioned configuration, the top of the hot water device, which is a rectangular parallelepiped and placed on the pallet member, is covered by the top member. The side plate portions extending downward from the opposing long sides of the top plate portion of the top member are provided with spacer attachment portions. The spacer attachment portions are provided with spacer members for cushioning. Ceiling material Lateral outside Inserted from , so that it protrudes outward from the side plate It is fixed. This spacer member functions to support the spacer members of the top members of adjacent water heaters during transportation, thereby suppressing rocking. Since the spacer member is inserted from the outer side of the top member, The spacer member can be made smaller, thereby saving materials and reducing the manufacturing cost of the packaging structure for the hot water device.

[0009] Also,The spacer member is inserted and fixed into first and second horizontally elongated through-holes spaced a predetermined distance apart in the vertical direction in the spacer attachment section provided at the upper center in the width direction of the side plate section of the top member. Therefore, by fixing the spacer member in two places, it is possible to prevent the spacer member from shifting or falling off.

[0010] Claim 2 The packaging structure of the hot water device of the invention is as follows: 1 In the invention, the spacer member has a main body portion having a cushioning function, a first insertion portion extending laterally from an upper portion of the main body portion and inserted into the first insertion hole, and a second insertion portion extending from a lower portion of the main body portion in the same direction as the first insertion portion and inserted into the second insertion hole, and the first insertion portion has a tip portion whose width is greater than the length of the first insertion hole, and a base portion whose width is smaller than the length of the first insertion hole due to both widthwise ends being cut out in the width direction. According to the above configuration, the width of the first insertion portion of the spacer member is greater than the length of the first insertion hole at the tip end and is smaller than the length of the first insertion hole at the base end. Therefore, when the first insertion portion is inserted into the first insertion hole up to the base end, the tip end engages with the side plate of the top member and becomes difficult to come out, thereby preventing the spacer member from falling off.

[0011] Claim 3 The packaging structure of the hot water device of the invention is as follows: 2 In the invention, in order to protect the upper corners of the hot water device, a top pad member with an L-shaped cross section is arranged along the long side of the top plate portion on the inside of the top member, and the lower end of the top pad member is supported by the second insertion portion inserted into the second insertion hole. According to the above-described configuration, the water heating apparatus can be covered with the top pad member attached to the top member, which makes it easy to pack the water heating apparatus.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, the mode for carrying out the present invention will be described based on examples. EXAMPLES

[0015] The hot-water unit H is formed in a thin rectangular parallelepiped shape that is long in the vertical direction in order to reduce the installation space and to install it close to the exterior wall of a building so as to reduce the distance it protrudes from the exterior wall. As shown in Fig. 1, the hot-water unit packaging structure 1 for packaging this hot-water unit H has a pallet member 2 whose mounting surface is larger than the bottom surface of the hot-water unit H to be placed on, side packaging members 3 formed, for example, by folding a cardboard sheet, a top member 10 formed in a box shape with an open bottom, and a plurality of band members 4, 5 for fixing and integrating these.

[0016] The hot-water apparatus H placed on the pallet member 2 is covered with the top member 10 with most of the sides being covered by the side packaging members 3, and the top of the hot-water apparatus H is covered by the top member 10 together with the top of the side packaging members 3. In this state, the outer periphery of the side packaging members 3 is fastened with band members 4, and the pallet member 2 and the top member 10 are fastened with band members 5, thereby fixing the packaging structure 1 for the hot-water apparatus.

[0017] As shown in Figures 2 to 4, the top member 10 has a rectangular top plate portion 10a and side plate portions 10b to 10e extending downward from the four sides of the top plate portion 10a. The side plate portion 10b extending from one long side of the rectangular top plate portion 10a is provided with a spacer mounting portion 11 for mounting a buffer spacer member 15 at the center upper part in the width direction of the side plate portion 10b near the corner formed by the top plate portion 10a and the side plate portion 10b. The side plate portion 10d extending from the other long side of the top plate portion 10a is also provided with a spacer mounting portion 12 similar to the spacer mounting portion 11.

[0018] Corresponding buffer spacer members 15 are fixed to these spacer mounting portions 11, 12. The spacer members 15 have a buffering function of filling the gaps between the top members 10 of adjacent water heating devices H to soften collisions and impacts when multiple water heating devices H are loaded onto a transport vehicle so that no gaps are formed between the pallet members 2.

[0019] Top member 10, which is formed in a box shape with an open bottom, is placed over the top of the hot water devices H and fixed with band members 5 (see FIG. 1). When a transport vehicle carrying multiple hot water devices H packaged in packaging structure 1 for hot water devices sways, the hot water devices H tend to swing in the direction in which the width of the bottom is narrower (left and right direction in FIG. 4). However, there are no gaps between adjacent hot water devices H at the bottom due to pallet member 2, and at the top due to spacer members 15 fixed to side plate portions 10b, 10d of top member 10. Therefore, multiple hot water devices H support each other and are less likely to swing, which makes it possible to prevent damage to or tipping over of the hot water devices H due to the swinging.

[0020] The spacer attachment portions 11 and 12 will be described with reference to FIGS. The spacer mounting portion 11 has a horizontally long first insertion hole 11a formed near the upper end of the side plate portion 10b close to the corner formed by the top plate portion 10a and the side plate portion 10b, and a horizontally long second insertion hole 11b formed at a position spaced a predetermined distance downward from the first insertion hole 11a. The length of the second insertion hole 11b in the width direction (left-right direction) of the side plate portion 10b is shorter than the length of the first insertion hole 11a. The spacer mounting portion 12 has the same structure as the spacer mounting portion 11 and therefore will not be described, but has a horizontally long first insertion hole 12a and a horizontally long second insertion hole 12b shorter than the first insertion hole 12a.

[0021] The spacer member 15 will be described with reference to FIGS. The spacer member 15 has a main body portion 15a having a shock-absorbing function, a first insertion portion 15b inserted into the first insertion hole 11a, and a second insertion portion 15c inserted into the second insertion hole 11b. The main body portion 15a is formed with a U-shaped cross section by an upper portion (main body portion upper portion 15d), a side portion (main body portion side portion 15e), and a lower portion (main body portion lower portion 15f) of the main body portion 15a so that the main body portion 15a becomes a rectangular parallelepiped spacer member 15 when fixed to the spacer mounting portion 11 of the side plate portion 10b. The inside of the main body portion 15a is partitioned into a cylindrical shape with a triangular cross section by a reinforcing portion 15g that connects the end portion of the main body portion lower portion 15f on the side plate portion 10b side and the corner portion formed by the main body portion upper portion 15d and the main body portion side portion 15e, and deformation of the main body portion 15a is suppressed.

[0022] The first insertion portion 15b extends laterally (toward the side plate portion 10b) from a portion of the main body upper portion 15d on the side plate portion 10b side. The first insertion portion 15b has a tip portion 15h whose width is greater than the length of the first insertion hole 11a, and a base portion 15i whose width is smaller than the length of the first insertion hole 11a. The tip portion 15h has an inclined portion formed so that the width becomes narrower toward the tip side. The second insertion portion 15c has a width equal to the length of the second insertion hole 11b, and extends from the widthwise center of the main body lower portion 15f in the same direction as the first insertion portion 15b.

[0023] The spacer member 15 is formed, for example, by forming a rectangular cardboard sheet into a predetermined shape having first and second insertion portions 15b and 15c, and bending it into a cylindrical shape. As shown in Fig. 7, two adjacent corners of the rectangular cardboard sheet are cut diagonally to form an inclined portion whose width becomes narrower toward the tip side, and cutout portions 15j and 15k of the same length are cut out in an elongated rectangular shape from both ends of the cardboard sheet facing each other in the width direction toward the center in the width direction. This forms the first insertion portion 15b having a tip portion 15h having an inclined portion and a base end portion 15i of the first insertion portion 15b whose width is narrower than the tip portion 15h.

[0024] The first insertion portion 15b having a base end 15i and a tip end 15h extends from a portion of the cardboard sheet that will become the main body 15a of the spacer member 15. The sum of the length of the notch 15j or the notch 15k and the width of the base end 15i of the first insertion portion 15b is approximately equal to the length of the first insertion hole 11a. In other words, the length obtained by subtracting the length of the notch 15j or the notch 15k from the width of the first insertion portion 15b is approximately equal to the length of the first insertion hole 11a.

[0025] The portion of the cardboard sheet that becomes the main body 15a of the spacer member 15 has three folded portions parallel to the width direction of the first insertion portion 15b, which are designated as the first folded portion 15m, the second folded portion 15n, and the third folded portion 15p, in that order from the first insertion portion 15b side. The portion between the base end portion 15i of the first insertion portion 15b and the first folded portion 15m becomes the main body upper portion 15d, and the portion between the first folded portion 15m and the second folded portion 15n becomes the main body side portion 15e. The portion between the second folded portion 15n and the third folded portion 15p becomes the main body lower portion 15f, and the portion from the third folded portion 15p to the end opposite the first insertion portion 15b becomes the reinforcing portion 15g.

[0026] Two insertion protrusions 15q are formed at the end of the reinforcing portion 15g opposite to the first insertion portion 15b. Two openings 15r for inserting the two insertion protrusions 15q of the reinforcing portion 15g are formed at positions corresponding to the two insertion protrusions 15q in the vicinity of the first bent portion 15m of the main body portion upper portion 15d. The center portion of the third bent portion 15p is cut out in a U-shape from the reinforcing portion 15g so as to protrude from the main body portion lower portion 15f toward the two insertion protrusions 15q side, and a second insertion portion 15c extending from the main body portion lower portion 15f is formed.

[0027] The cardboard sheet formed into a predetermined shape as described above is folded in the same direction at the first folding portion 15m to the third folding portion 15p, and the main body side portion 15e, the main body lower portion 15f, and the reinforcing portion 15g form a tube with a triangular cross section. Then, the two insertion protrusions 15q are inserted into the corresponding two openings 15r to fix the shape of the tube, thereby forming the spacer member 16. By folding the third folding portion 15p, the second insertion portion 15c is in a state of protruding from the main body lower portion 15f. In addition, when the first insertion portion 15b extending from the main body upper portion 15d of this spacer member 15 is in a horizontal position, the base end portion 15i of the first insertion portion 15b and the second insertion portion 15c are positioned to overlap in the vertical direction.

[0028] The attachment of the spacer member 15 will be described with reference to FIG. First, as shown in the upper part, the first insertion portion 15b is inserted obliquely into the first insertion hole 11a of the spacer attachment portion 11 from the side of the side plate portion 10b, and the side plate portion 10b is fitted into, for example, the notch portion 15j as one of the notches in the base end portion 15i of the first insertion portion 15b. Next, as shown in the middle part, while inserting the other notch portion 15k so as to approach the side plate portion 10b, the spacer member 15 is moved in the width direction of the side plate portion 10b so that the side plate portion 10b fits into the entire notch portion 15j, and the position of the notch portion 15k is aligned with the side plate portion 10b. Then, as shown in the lower part, the spacer member 15 is moved in the width direction of the side plate portion 10b so that the side plate portion 10b fits into a part of the notch portion 15k.

[0029] In this manner, the tip 15h of the first insertion portion 15b, which has a width greater than the length of the horizontally elongated first insertion hole 11a, is inserted into the first insertion hole 11a. Then, the upper portion 15d of the main body and the tip 15h of the first insertion portion 15b engage with the side plate portion 10b, restricting the movement of the first insertion portion 15b in the insertion direction and in the direction opposite to the insertion direction (removal direction). In this state, the second insertion portion 15c is inserted into the second insertion hole 11b, restricting the movement of the side plate portion 10b of the spacer member 15 in the width direction, and the spacer member 15 is fixed to the top member 10. The spacer member 15 is also fixed to the spacer attachment portion 12 in the same manner as described above.

[0030] As shown in Figs. 3 and 9, a top pad member 18 formed in an L-shaped cross section along the corner is disposed inside the top member 10 in order to protect the upper corner of the wide side of the hot water device H. At this time, the lower end of the top pad member 18 is supported by the second insertion portion 15c of the spacer member 15 inserted into the second insertion hole 11b. Also, the upper end of the top pad member 18 abuts against the first insertion portion 15b of the spacer member 15 inserted into the first insertion hole 11a, and the top pad member 18 is sandwiched between the first insertion portion 15b and the second insertion portion 15c. This makes it possible to attach the top pad member 18 to the inside of the top member 10, and the top pad member 18 can be easily placed together with the top member 10 over the hot water device H, which is tall.

[0031] The function and effect of the packaging structure 1 for the hot water device will be described. The top member 10 is placed on the hot water device H placed on the pallet member 2 to cover the top of the hot water device H. Side plate portions 10b, 10d extending downward from opposing long sides of a top plate portion 10a of the top member 10 are provided with spacer mounting portions 11, 12. Corresponding spacer members 15 for cushioning are attached to the side of the spacer mounting portions 11, 12. outside Inserted from , so as to protrude outward from the side plate portions 10b and 10d. It is fixed. The spacer members 15 function to support each other with the spacer members 15 of the top members 10 of the adjacent water heating devices H during transportation of a plurality of water heating devices H, thereby suppressing rocking. In addition, the spacer member 15 can be made smaller than the conventional type that is placed over the top member 10, saving material and reducing the manufacturing cost of the packaging structure 1 for the hot water device.

[0032] In addition, in the spacer mounting portion 11 provided at the upper center in the width direction of the side plate portion 10b of the top member 10, the corresponding spacer member 15 is inserted and fixed into the horizontally elongated first insertion hole 11a and second insertion hole 11b spaced a predetermined distance apart in the vertical direction. Similarly, in the spacer mounting portion 12 provided at the upper center in the width direction of the side plate portion 10d of the top member 10, the corresponding spacer member 15 is inserted and fixed into the horizontally elongated first insertion hole 12a and second insertion hole 12b spaced a predetermined distance apart in the vertical direction. By fixing the spacer member 15 at two points, top and bottom, it is possible to prevent the spacer member 15 from shifting or falling off.

[0033] The width of the first insertion portion 15b of the spacer member 15 is greater than the length of the first insertion holes 11a, 12a at the tip end 15h and is smaller than the length of the first insertion holes 11a, 12a at the base end 15i. Therefore, when the first insertion portion 15b is inserted up to the base end 15i of the spacer member 15 corresponding to the first insertion holes 11a, 12a, the tip end 15h engages with the side plate portions 10b, 10d of the top member 10 and becomes difficult to come out, so that the spacer member 15 can be prevented from shifting or falling off.

[0034] In order to protect the upper corners of the hot water device H, top pad members 18 each having an L-shaped cross section are disposed along the opposing long sides of the top plate portion 10a inside the top member 10. The bottom end of the top pad members 18 is supported by the second insertion portions 15c inserted into the second insertion holes 11b, 12b, respectively. Since the hot water device H can be covered with the top pad members 18 attached to the top member 10, packaging of the hot water device H becomes easy.

[0035] In addition, a person skilled in the art can implement the present invention in a form in which various modifications are added to the above-described embodiment without departing from the spirit of the present invention, and the present invention includes such modifications.
