Description

  The present invention relates to a packaging structure.

  Conventionally, as a packing structure for an object to be packed, it is known to support and store the object to be packed in a cardboard outer box via a cardboard support (see, for example, Patent Document 1). However, in a structure in which the object to be packed is supported by a relatively rigid corrugated cardboard support, the impact applied to the outer box propagates directly to the object to be packed through the support and damages the object to be packed. There is a problem that there is a high risk of making it happen.

In addition, in order to protect the packaged goods from external impacts and pack them, it is common to lay cushioning materials such as air bags around the packaged goods. Depending on the case, there is a problem that the air bag is not interposed between the outer box and the packaged item is not reliably protected.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a packing structure that enables packing with reliable protection of an object to be packed with a simple structure. Is.

In order to solve the above-described problem, in the packing structure according to claim 1, the substantially U-shaped support material 2 formed by raising the pair of side pieces 6 from both ends of the bottom piece 5 is used as the bottom piece 5 and the pair of side pieces. The buffer body 1 is formed by being inserted into the annular flexible sheet 3 having a circumferential dimension shorter than the circumferential dimension in the continuous direction 6. A pair of shock absorbers 1 are brought close to each other to be packed 4 so as to be inserted into the groove 2a, and between the tips of the pair of side pieces 6 in the flexible sheet 3 of each shock absorber 1. alternating the direction multiplied passed a package structure each Ru is supported object to be packed 4 to the site, to substantially opposed and staggered a plurality of cushion 1 in the longitudinal direction of the object to be packed 4 of the long object to It is characterized by being arranged in a staggered manner in proximity to each other.

According to this, by inserting the article to be packed 4 into the U-shaped groove 2a of each support member 2 by bringing the pair of shock absorbers 1 close to each other from the direction substantially opposite to the article to be packed 4, each flexibility The package 4 can be sandwiched and held so as to wrap the package 3 between the ends of the pair of side pieces 6 in the sheet 3, that is, the package 4 is a flexible sheet 3 that follows its shape. The external sheet is hardly suspended by the flexible sheet 3 and the packaged object 4 wrapped by the flexible sheet 3 is out of the holding state. The shock absorber 1 for packing the article 4 to be packed is provided with a substantially U-shaped support material 2 formed by raising a pair of side pieces 6 from both ends of the bottom piece 5. 5 and shorter than the circumferential dimension in the continuous direction of the pair of side pieces 6 It can be easily formed by inserting it into the annular flexible sheet 3 having dimensions, that is, it enables packaging with reliable protection of the article 4 to be packed by a simple structure. It can be done. Further, it is not necessary to interfere the buffer bodies 1 sandwiching the packaged object 4 from both sides, and the flexible sheet 3 of the buffer body 1 can wrap a part of the packaged object 4 having a half cross section or more. Thus, it is possible to perform packing with reliable protection of the object to be packed 4 of the scale.

  In this invention, it has the advantage that packing with the reliable protection of a to-be-packaged object can be enabled by simple structure.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  1 and 2 show an example of an embodiment of the present invention. This example has a pair of parallel substantially circular end surfaces 4a, and the peripheral side surface 4b connecting the pair of end surfaces 4a has a columnar shape with different diameters in the direction connecting the end surfaces 4a (specifically, the peripheral side surface 4b is This is a packing structure in which an article to be packed 4 formed in a column shape whose diameter gradually increases as it approaches the end surface 4a with the central portion between the end surfaces 4a as the minimum diameter portion is packed with a packing material.

  The packing material includes an outer box (not shown), a pair of shock absorbers 1 that are accommodated in the outer box and support the article 4 to be packed, and upper and lower pad bodies 7. As shown in FIG. 2, the shock absorber 1 includes a substantially U-shaped corrugated cardboard support member 2 formed by bending and standing up a pair of side pieces 6 from both ends of the bottom piece 5, and a continuous piece of the bottom piece 5 and the pair of side pieces 6. It is formed by being inserted into an annular flexible sheet 3 having a circumferential dimension shorter than the circumferential dimension in the direction. Here, a U-shaped groove 2 a surrounded by the bottom piece 5 and the pair of side pieces 6 is formed in the substantially U-shaped support material 2. The annular flexible sheet 3 is made of polyethylene bag material having a thickness of about 80 μm. The pad body 7 can be made of a cardboard plate material, for example.

  Then, as shown in FIG. 1, the direction in which the pair of shock absorbers 1 are substantially opposed to the peripheral side surface 4 b of the packaged object 4 so that the packaged object 4 is inserted into the U-shaped groove 2 a of the support material 2. The peripheral side surface 4b of the article to be packed 4 is supported on the portion of the flexible sheet 3 of each buffer body 1 that is spanned between the tips of the pair of side pieces 6 and The pad bodies 7 are arranged along the end surfaces 4a, respectively, and stored in the outer box. Specifically, the buffer body 1 is formed by covering the support material 2 with the annular flexible sheet 3, but the portion of the flexible sheet 3 that supports the article to be packed 4 is that of the support material 2. The remaining part of the outer peripheral surface covering portion 3b covering the outer peripheral surface of the bottom piece 5 and the pair of side pieces 6, spanned between the tips of the pair of side pieces 6, This is performed by the support portion 3a, which is a portion separated from the inner peripheral surface of the U-shaped groove 2a of the pair of side pieces 6. In addition, you may bind the buffer body 1 and the pad body 7 which supported the to-be-packaged object 4 with the binding tools, such as a string, instead of an outer box.

  Thus, in the packing structure of this example, the pair of shock absorbers 1 are brought close to each other from the direction substantially opposed to the package 4 and the package 4 is inserted into the U-shaped groove 2 a of each support member 2. Thus, it is possible to sandwich and hold the packaged object 4 so as to wrap around the portion of the flexible sheet 3 between the ends of the pair of side pieces 6. The object to be packaged is suspended in the air by the flexible sheet 3 along the line, the impact from the outside is hardly transmitted to the object to be packed 4 by the flexible sheet 3, and is wrapped by the flexible sheet 3. No. 4 is protected in a state that does not break from the holding state.

  Here, the shock absorber 1 for packing the article to be packed 4 includes a substantially U-shaped support material 2 formed by raising a pair of side pieces 6 from both ends of the bottom piece 5, and a continuous direction of the bottom piece 5 and the pair of side pieces 6. It can be easily formed by inserting it into the inside of the annular flexible sheet 3 having a circumferential dimension shorter than the circumferential dimension. That is, packing with reliable protection of the article 4 is enabled by a simple structure.

  In the packing structure of this example, it is the flexible sheet 3 that directly contacts and supports the object 4 to be packed, and the flexible sheet 3 is bent and deformed along the shape of the object 4 to be packed. Since the object 4 can be supported, the packaged object 4 can cope with any shape of an irregular shape. Furthermore, if the flexible sheet 3 is provided with elasticity that can be somewhat expanded and contracted, the width of the shape of the packaged object 4 that can be accommodated can be increased (the versatility to the packaged object 4 can be improved). )preferable.

  Further, the U-shaped support material 2 of the buffer body 1 only needs to have rigidity sufficient to withstand the load from the flexible sheet 3 that supports the article 4 to be packed. For example, a frame assembled in a U-shape. It may be a material, or may be formed by bending a single cardboard board as in this example. When the support material 2 is made of a single cardboard plate as in this example, the support material 2 can be formed by bending the cardboard plate at the time of packaging, that is, before the packaging, the planar shape constituting the support material 2 can be formed. These cardboard plates can be stacked and stored together with the flexible sheet 3 in a flattened state, and the storage volume of the packing material before packing can be reduced.

  3 to 5 show other examples of the embodiment of the present invention. This example is a packing structure in which a long article to be packed 4 is packed with a packing material, and the same parts as those in the previous example are denoted by the same reference numerals, description thereof is omitted, and different parts are described. Specifically, as the long packaged object 4 of this example, as shown in FIG. 5, a main body 41 having a drive unit disposed on the ceiling, and a clothes hanger suspended from and supported by the main body 41. 42, and the packing state of the article 4 to be packed, which is composed of the main body 41 and the laundry basket 42, is a plate-shaped partition pad body 8 ( This is a state in which the clothes-drying basket 42 is placed through FIG.

  The packing material includes an outer box, a plurality of (in this example, five) buffer bodies 1 and a pair of pad bodies 7 that are accommodated in the outer box and support the article 4 to be packed. The plurality of shock absorbers 1 are arranged in a staggered manner by shifting in the length direction of the long packaged object 4 and alternately approaching from substantially opposing directions. Specifically, the shock absorber 1 of this example includes three lower shock absorbers 1a (FIG. 4 (a)) that support the object to be packed 4 placed from below, and two upper shock absorbers that hold the object to be packed 4 from above. It is comprised with the body 1b (FIG.4 (b)). The size of the lower buffer body 1a along the length direction of the object to be packed 4 is approximately twice as long as that of the upper buffer body 1b, so that the rigidity can be increased to withstand the weight of the object to be packed 4. Has been. FIG. 4C shows a flexible sheet 3a constituting the lower shock absorber 1a, and FIG. 4D shows a flexible sheet 3b constituting the upper shock absorber 1b. The dimension of the flexible sheet 3a along the length direction of the article to be packed 4 corresponds to the dimension of each of the shock absorbers 1a and 1b along the length direction of the article to be packed 4 and is approximately 2 of the flexible sheet 3b. It has a double length. Here, the dimension along the length direction of the article 4 to be packed in each flexible sheet 3 is formed to be slightly longer than the corresponding support material 2, and insertion error of the support material 2 into the flexible sheet 3 is caused. Even in such a case, the flexible sheet 3 is surely covered with the support material 2. In addition, the circumferential length of the flexible sheet 3 is formed to be approximately 90% shorter than the circumferential dimension in the continuous direction of the bottom piece 5 and the pair of side pieces 6 of the support member 2. .

  Further, the pad body 7 is formed into a flat rectangular cylindrical body by bending one cardboard plate as shown in FIG. The pad body 7 is arranged along both sides in the length direction of the article 4 to be packed. As described above, the object to be packed 4 is supported by the plurality of shock absorbers 1 and the pad bodies 7 are arranged at both ends of the object to be packed 4, and these are accommodated in a cardboard outer box. In this example, as shown in FIG. 4 (f), the outer box uses a pair of substantially U-shaped outer box members 9 formed by bending and standing up a pair of side piece portions 9b from both ends of the bottom piece portion 9a. As shown in FIG. 5, the side pieces 9 b are overlapped and connected to each other in a state where the packing object 4, the buffer body 1, and the pad body 7 are positioned between the pair of outer box materials 9, The packaged object 4, the buffer body 1, and the pad body 7 are formed so as to be housed. For example, as shown in FIG. 6, the packaged object 4, the buffer body 1, and the pad body 7 are contained in one outer box material 9. It is also preferable that the outer surface material 10 is wound around the outer box material 9 and formed.

  In the packing structure of this example, the same effect as the previous example is obtained, and a plurality of cushioning bodies 1 are shifted in the length direction of the long packaged object 4 and alternately from the substantially opposite direction. Since they are arranged close to each other in a staggered manner, the adjacent buffer bodies 1 sandwiching the package object 4 from both sides can be prevented from interfering with each other. That is, the flexible sheet 3 of the buffer body 1 can be packaged. 4 and more than half of the cross section (specifically, the lower buffer 1a encloses the lower half of the package 4 and the upper buffer 1b covers the upper half of the package 4). Advantages of being able to increase the contact area of the flexible sheet 3 to the object to be packed 4 and enabling packing with reliable protection of the long object 4 to be packed. It also has.

  Furthermore, in the packing material of this example, as shown in FIG. 4, all members other than the flexible sheet 3 of the shock absorber 1 are formed by bending a single cardboard plate. That is, the packaging material is unified, and there is an advantage that simplification and low cost of the packaging material and, consequently, the packaging structure are secured.

It is a perspective view of the packing structure of the example of embodiment of this invention. It is a disassembled perspective view of a buffer body same as the above. It is a perspective view of the packing structure of the other example of embodiment of this invention. (A)-(g) is the expanded view which notched one part about each member of the packaging material same as the above. It is a schematic sectional drawing in the AA of FIG. It is front sectional drawing which shows the other example of an outer case.
