Description

  The present invention relates to a packaging method.

  In recent years, modeling apparatuses (3D printers) that model various three-dimensional shaped objects are becoming widespread. In such a modeling apparatus, for example, a modeled object is modeled by various methods such as a layered modeling method (see, for example, Patent Document 1).

JP, 2015-71282, A

  When a modeling object is modeled with a modeling apparatus, it may be necessary to transport (carry) to another place after modeling is completed. In this case, depending on the shape of the modeled object, it is necessary to pack the modeled object using a packing box or the like, for example, in order to suppress the influence of impact during transportation. In this case, a buffer material (cushion material) that cushions the impact may be used in order to prevent the molded article from being damaged even if the molded article is shaken due to an impact applied to the packaging box during transportation. . Moreover, as such a buffer material, for example, a polyethylene bubble buffer material, a polyurethane foam buffer material, a sponge or the like is used. Such a method is actually effective to some extent.

  However, when the inventors of the present application actually conducted experiments to transport shaped objects of various shapes, for example, a shaped object having a fine structure (for example, a thin shaped object or a thin shaped object) In addition, when transporting a model that is easily damaged, it has been found that even if packing is performed using the cushioning material as described above, the model may not be sufficiently damaged. Further, the inventor of the present application, regarding the cause of such breakage, for example, when using the cushioning material as described above, the cushioning material or the molded article slightly moves due to impact during transportation, etc. It was found that it was because it was strongly pressed against the modeled object. In addition, such slight movement of the cushioning material or the modeled object is not limited to the case of receiving a strong impact, but the static pressure partially varies depending on the non-uniform arrangement between the cushioning material and the modeled object. It may also be caused by slight operations before and after transportation or during long-term storage. Therefore, in this case, for example, it is conceivable that a fine structure portion of the modeled object is damaged before and after transportation or during long-term storage. As a result, the molded article is exposed to a risk of breakage, not only during transportation.

  On the other hand, for example, when a polyurethane foam cushioning material is used as the cushioning material, it is configured to swell and fix the modeled object in the packing box, and therefore the movement of the buffering material or the modeled object in the packing box hardly occurs. However, in this case, a strong force is partially applied to the modeled object at the timing when the polyurethane foam cushioning material swells or when the cushioning material is removed after transportation. As a result, it is considered that a molded article having a fine structure is likely to be damaged. In this case, for example, if the modeled object is formed of a resin or the like, the modeled object may be deformed due to the influence of heat generated during foaming.

  Further, for example, in the case of a modeled object manufactured using gypsum as a material, damage is particularly likely to occur even if the above-described cushioning material is used due to its brittleness. Moreover, the modeled object modeled with the modeling apparatus is not usually a mass-produced product. For this reason, it is usually difficult to produce a member such as a blister case for transportation. Moreover, in a modeling apparatus, a modeling thing may be modeled, forming the support layer which supports the circumference | surroundings of the modeling thing under modeling. In this case, if the model is transported with the support layer remaining, it is considered that the model can be hardly damaged. However, in this case, it is necessary to remove the support layer on the side that receives the transported modeled object (for example, the customer side), which places a heavy burden on the side that receives the modeled object.

  Moreover, the above problems occur not only when a modeled object modeled by the modeling apparatus is transported but also when various solid objects (objects) are packed. Therefore, conventionally, it has been desired to pack a three-dimensional object by a more appropriate method. Then, an object of this invention is to provide the packing method which can solve said subject.

  The inventor of the present application has further studied diligently about the cause of damage in a state where a three-dimensional part such as a modeled object is packed. Specifically, for example, an experiment for transporting a three-dimensional object was repeatedly performed, and the state of damage during transportation or packaging was confirmed. And based on the confirmation result etc., it discovered that it was easy to cause a damage that a modeling thing moved with respect to the surrounding buffer material within a packaging box. Moreover, based on such knowledge, it was thought that damage would not easily occur unless the modeled object and the surrounding objects move relatively in the packaging box. And in order to satisfy | fill such conditions, for example, a modeling thing is completely buried in the packing box filled with the filler of powder or a granular material (powder or particulate form), for example, pressure is applied from one direction. Thus, it was considered to fix the relative position of the filler with respect to the modeled object. In this case, by utilizing the repulsion from the packing box, the modeled object is pressed from all directions according to the law of action and reaction. In addition, due to this compression, the modeled object and the surrounding fillers do not move relatively in the packing box.

  In addition, it is considered that breakage of the packaged model is particularly likely to occur when a part that is easily damaged in the model is subjected to compression from one direction. On the other hand, when a molded article is packed in this manner, the molded article is more appropriately prevented from being damaged by being pressed with the same force from all directions. Furthermore, the inventor of this application repeated the experiment which conveys the modeling object packed on such conditions, and confirmed that the effect which prevents a damage was acquired appropriately. Further, through further earnest research, the inventors have found characteristics necessary for obtaining such an effect and have reached the present invention.

  In order to solve the above-described problems, the present invention provides a packing method for packing a three-dimensional object, which is a three-dimensional object, and a storage container that is a container that stores the three-dimensional object, and is filled in the storage container. A storage step of storing the three-dimensional object and the filler in the storage container so that a periphery of the three-dimensional object is surrounded by the filler, and at least the storage container A step of preventing a part of the filler from moving relative to the three-dimensional object, and the relative position of the filler around the three-dimensional object with respect to the three-dimensional object in contact with the three-dimensional object By fixing the at least one of the fillers in contact with the three-dimensional object, the container does not move relative to the three-dimensional object even when the container receives an impact of a predetermined size or less. Filler to make And a location fixed stage.

  When comprised in this way, it can prevent appropriately that a solid thing and a filler move within a storage container, for example by making a filler not move with respect to a solid object within a storage container, for example. Thereby, for example, even when the receiving container receives an impact during transportation or the like, it is possible to appropriately prevent the three-dimensional object from being damaged. Therefore, if comprised in this way, a solid thing can be packed appropriately, for example.

  Here, with respect to the impact received by the storage container, the impact below a preset magnitude is, for example, an impact below the upper limit set according to the required impact resistance. Moreover, in this method, the periphery of the three-dimensional object is surrounded by the filler, for example, when the three-dimensional object is buried in the filler, so that the entire periphery of the three-dimensional object is surrounded by the filler. As the filler, for example, it is preferable to use a filler that does not adhere firmly to the three-dimensional object even if it comes into contact with the three-dimensional object, and that can be easily removed from the three-dimensional object. Further, depending on the shape or the like of the three-dimensional object, it may be necessary to protect only a portion that is fragile due to impact or the like (a part of the three-dimensional object). In such a case, it is also conceivable to perform packing so that only a part of the three-dimensional object is buried in the filler. In this case, it can be considered that the periphery of the three-dimensional object is surrounded by the filler, or the like that the part of the three-dimensional object is surrounded by the filler.

  Moreover, as a filler, it is possible to use a powder or a granule, for example. In this case, it is preferable to use dry powder or granules. More specifically, silica gel or starch powder can be used as the filler. It is also possible to use sand or the like as the filler. Moreover, as a filler, it is possible to use not only these but desiccants other than a silica gel, various organic materials, an inorganic material, etc. For example, it is possible to use pearlite or vermiculite as the filler. Further, the filler is not limited to one type of filler, and a plurality of types of fillers may be used in combination. Moreover, as a filler, using a hollow resin etc. is also considered, for example. Moreover, about the structure which uses a powder or a granule as a filler, it can also be considered as the structure etc. which use the filler which consists of multiple (many) materials, for example. With such a configuration, for example, the filler that is in contact with the three-dimensional object can be prevented from moving with respect to the three-dimensional object even when the receiving container receives an impact. When focusing on these features, for the operation of the filler position fixing stage, for example, consider the operation of fixing the relative position of the filler that exhibits fluidity to the three-dimensional object in contact with the three-dimensional object. You can also. In this case, it is preferable to use a powder or a particle having fluidity as the powder or particle. The phrase “powder and granules exhibit fluidity” means, for example, that a large number of powders and granules exhibit fluidity as an aggregate. Further, in this case, the powder and the particles exhibit fluidity, so that, for example, the filling material is filled around the three-dimensional object without any gap at the time of filling. As a result, partial movement of the three-dimensional object due to an impact from the outside is suppressed, and breakage of the three-dimensional object can be prevented appropriately. Note that a part of the filler may be replaced with a solid material such as a resin, a metal, or a piece of wood. In this case, it is preferable that the solid material is filled in a position sufficiently separated as long as it does not contact the three-dimensional material.

  In this case, for example, a container having a fixed shape can be suitably used as the container. The fixed shape container is not a deformable container such as a plastic bag, but a container that maintains a fixed shape even when the contents are empty (a hard container). Further, it is preferable that the filler in the container is in a finely packed state after at least the operation of the filler position fixing stage. If comprised in this way, the state which does not move relatively with respect to a three-dimensional object can be appropriately implement | achieved, for example, even when a storage container receives an impact about the filler in contact with at least a three-dimensional object. Further, it is preferable to use an inelastic body as the filler. If comprised in this way, for example, it will be possible to appropriately perform filling with fine filling without causing crushing or the like in the filler and without forming a space with the three-dimensional object. In this case, it is conceivable to apply pressure to the filler using a known cushioning material for packing. More specifically, in this case, for example, the buffer material or the like is further accommodated in the storage container so as to come into contact with the filler from the outside in the storage container, and a force for compressing the buffer material or the like is applied. The pressure can be applied to the filler via In this case, for example, a polyethylene cushioning material, a polyurethane foam cushioning material, a sponge, an air cushion, or cotton can be suitably used as the cushioning material. In this case, for example, it is preferable to install a cushioning material or the like so as to press the filler from one direction. If comprised in this way, a pressure can be appropriately applied to the filler in a storage container, for example.

  Moreover, in order to prevent damage to a three-dimensional object more appropriately, it is preferable that the dimension (size) of the filler is sufficiently small with respect to the dimension of a fragile part in the three-dimensional object. More specifically, in this case, for example, when the dimension of the fragile portion of the three-dimensional object is about 2 mm, it is preferable to use powder or granules having a dimension of 2 mm or less as the filler. In this case, the dimension of the filler such as powder or granules is a substantial dimension that is statistically determined, such as an average dimension. Moreover, when packing by such a method, since a solid thing can be packed appropriately without using a blister case for transportation, etc., it becomes possible to pack a solid object of various shapes at a low cost. . Therefore, as a three-dimensional object to be packed, for example, a modeled object that has been modeled with a modeling apparatus (three-dimensional modeling apparatus) can be suitably used. More specifically, in this case, as a modeling apparatus, for example, a modeling apparatus that performs modeling by an ink jet lamination method by stacking a plurality of ink layers formed by an ink jet head, or a modeling by a powder lamination method is performed. A modeling apparatus etc. can be used suitably.

  Further, the specific packing method or the like in this packing method is not limited to the above, and various modifications can be made. For example, it is conceivable that at least a part of the space between the fillers is further filled with a liquid in the storage stage. If comprised in this way, the movement of the content of a storage container can be prevented more appropriately by filling the clearance gap between fillers with a liquid, for example. In order to prevent damage to the three-dimensional object more reliably, for example, multiple packing may be performed using an exterior member and a cushioning material that are members that cover the outside of the storage container. In this case, for example, it is conceivable to further perform an operation in an exterior stage of covering the storage container and the buffer material with the exterior member so that at least a part of the periphery of the storage container is in contact with the buffer material.

  It is also conceivable to use a configuration other than powder or granules as the filler. In this case, for example, it is conceivable to use a substance that changes phase from a liquid state to a solid state during the packaging operation. More specifically, in this case, for example, in the storage stage, the storage container is filled with a liquid filler. In the filler position fixing stage, it is conceivable to change the phase of the filler to a solid state. Also in this case, it is possible to appropriately prevent the three-dimensional object and the filler from moving in the container when the three-dimensional object is transported. Thereby, damage of a solid thing can be prevented appropriately. Moreover, as such a filler, it is possible to use fats and oils, for example. In this case, in the storage stage, for example, the temperature of the oil / fat is set to a temperature at which the oil / fat becomes liquid, and the oil / fat is filled in the storage container. In the filler position fixing stage, for example, the oil / fat is phase-changed to a solid state by lowering the temperature of the oil / fat to a temperature at which the oil / fat becomes solid. Moreover, as such fats and oils, it is possible to use edible fats and oils, such as lard and margarine, and various industrial fats and oils, for example. As these materials, it is conceivable to use materials that do not adversely affect the three-dimensional object such as impregnation, dissolution, and discoloration.

  According to the present invention, for example, a three-dimensional object can be appropriately packed.

  Hereinafter, embodiments according to the present invention will be described with reference to the drawings. Drawing 1 is a figure explaining an example of the packing method concerning one embodiment of the present invention. Fig.1 (a) shows an example of the member used for the packaging target object and packing in this example. The packing method of this example is a method of packing the shaped object 50 for transporting the shaped object 50 that is an example of a three-dimensional object or for long-term storage, and uses the container 100, the filler 120, and the cushioning material 140. Then, the modeled object 50 is packed. In this case, packing means to pack an object for transportation or long-term storage, for example. A three-dimensional object is a three-dimensional object.

  Moreover, among the structures shown in FIG. 1A, the modeled object 50 is a three-dimensional object modeled by a modeling apparatus (three-dimensional modeling apparatus). In this case, as the modeling apparatus, for example, a modeling apparatus that performs modeling by an ink jet lamination method by stacking a plurality of ink layers formed by an inkjet head, a modeling apparatus that performs modeling by a powder lamination method, or the like is preferably used. be able to. Further, as will be described in detail below, in this example, packing is performed so as to prevent the molded object 50 from being damaged. Therefore, as the modeled object 50, for example, a modeled object having a fragile part can be used. More specifically, as the modeled object 50, for example, a modeled object having a thin portion with a thickness of 10 mm or less (for example, about 1 to 10 mm) may be used. Moreover, the thickness of the fragile part in the molded article 50 may be, for example, 5 mm or less (for example, about 1 to 5 mm). Moreover, it is also conceivable to use a three-dimensional object other than the modeled object 50 as an object of packaging described below. More specifically, for example, when transporting a model or the like that is likely to be damaged during transportation, the model may be an object to be packed.

  Moreover, among the structure shown to Fig.1 (a), the storage container 100, the filler 120, and the shock absorbing material 140 are examples of the member used for packing of the molded article 50. FIG. Among these, the storage container 100 is a container (packaging container) that stores the shaped object 50 during packing. In the present example, the storage container 100 is a container having a fixed shape. In this case, the fixed-shaped container is not a deformable container such as a plastic bag, but a container (hard container) that maintains a fixed shape even when the contents are empty. In addition, the container 100 having a fixed shape may be a substantially fixed shape depending on the accuracy required for packaging. In this case, as described below, if it is possible to maintain a sufficiently constant shape in a state where the filler 120 is filled, even if a certain degree of deformation occurs before and after the filling of the filler 120, for example. Good. More specifically, in this example, the storage container 100 is a box-shaped container having a bottom surface 102, a side surface 104, and a lid 106. In this case, the bottom surface 102 and the side surface 104 are surfaces constituting a main body portion of the storage container 100 that stores the modeled object 50 and the like. The lid 106 is a member that covers the upper part of the main body of the storage container 100. As the container 100, for example, a container made of plastic, glass, metal, wood, or a combination thereof can be suitably used.

  The filler 120 is a substance that is filled in the storage container 100 when the molded object 50 is packed, and is accommodated in the storage container 100 together with the molded object 50 so that an extra gap is not formed in the storage container 100. For example, the container 100 is filled with fine packing. In this case, the fact that the filler 120 is filled in close packing means that the filler 120 is included in a unit volume so that the volume of the filler 120 is a maximum volume determined according to the shape of the filler, etc. is there. In this case, the volume of the filler 120 included in the unit volume is the volume of the portion occupied by the filler 120 in the unit volume. In addition, regarding the volume of the filler 120, the maximum volume determined according to the shape or the like of the filler 120 is, for example, the maximum volume when the filler 120 is not crushed. In this case, it is preferable to use an inelastic body as the filler 120. With this configuration, for example, the filling material 120 can be appropriately filled without being crushed or the like, and without forming a space with the model 50. Moreover, about the state with which the filler 120 was filled by close-packing, for example, the filler 120 around the molded article 50 is not substantially opened without moving a gap in which the filler 120 moves relative to the molded article 50. It can also be considered as a state in which the filler 120 is filled so as to be in close contact with the model 50. Although not shown, a part of the volume of the filler 120 may be replaced with a solid material such as resin, metal, or wood chip. In this case, it is preferable that the solid material is filled in a position sufficiently separated as long as it does not contact the shaped object 50. Furthermore, you may accommodate the some molded article 50 in the area | region (within the volume of the filler 120) with which the filler 120 is filled in the storage container 100. FIG.

  Moreover, in this example, as such a filler 120, powder or a granule is used, for example. In addition, as the powder and granules, powders and granules having fluidity are used. The phrase “powder and granules exhibit fluidity” means, for example, that a large number of powders and granules exhibit fluidity as an aggregate. Further, as the filler 120, for example, it is preferable to use a material that does not adhere firmly to the model 50 even if it contacts the model 50 and can be easily removed from the model 50. From this point of view, it is preferable to use a dry powder or granule as the filler 120. More specifically, in this example, for example, silica gel particles (silica gel particles) are used as the filler 120.

  In this case, for example, since the filler 120 does not adhere firmly to the modeled object 50, it is filled with, for example, a soft brush or the like without being washed in water when the modeled object 50 is taken out from the storage container 100 after transportation. By removing the material 120, it is possible to appropriately take out the shaped article 50 in a state where the excessive filler 120 does not adhere. Silica gel is not toxic and can be disposed of in general. Therefore, when silica gel is used as the filler 120, for example, also in this respect, the filler 120 can be easily and appropriately removed after necessary transportation or the like. Further, in this case, since the filler 120 absorbs the moisture in the container 100, such a problem occurs even when the molded object 50 that swells, changes, decays, discolors, or the like due to moisture absorption is packed. Can be prevented appropriately. Silica gel is available at a relatively low cost and can be used repeatedly by heat drying. Therefore, in this case, the cost of the filler 120 can be appropriately reduced.

  Here, in the case where the granular filler 120 is used as in this example, in order to prevent the molded article 50 from being damaged at the time of packing or after packing, the dimensions of the filler 120 (the size of the granular material, the diameter of the particles). ) Is preferably made sufficiently small with respect to the dimension of the fragile portion of the shaped article 50. In this case, to make the size of the filler 120 sufficiently small with respect to the dimension of the fragile portion in the model 50, for example, the filler 120 is thinner than the thickness of the thinnest part and the width of the thinnest part in the model 50. Is to reduce the size. More specifically, the dimension of the filler 120 is preferably 2 mm or less, for example. In this case, the dimension of the filler 120 is, for example, the length of the longest linear distance in each grain used as the filler 120. Moreover, the dimension of the filler 120 may be a substantially calculated | required substantial dimension like an average dimension, for example. Moreover, about the dimension of the filler 120, it can also be considered as the standard dimension etc. on a design, for example. Moreover, practically, the use of the filler 120 having a size of 2 mm or less means that 90% or more (preferably 95% or more, more preferably 99%) by weight among the many fillers 120 filled in the container. %) Of the filler 120 may be 2 mm or less. Further, the size of the filler 120 is more preferably 1 mm or less. In this example, the filler 120 is stored in a sealed container such as a bag until the container 100 is filled. And the required quantity is filled in the storage container 100 at the time of packing of the molded article 50.

  In addition, about the upper limit of the preferable dimension of the filler 120, it is thought that it changes with the material intensity | strength and fineness of the molded article 50 which is the object of packing. Further, in this case, it is considered that the smaller the size of the filler 120 is, the better, from the viewpoint of preventing the molded article 50 from being damaged. The features of the filler 120 will be described in more detail below with reference to FIGS. 1B and 1C.

  The cushioning material 140 is a cushioning member that is housed in the housing container 100 together with the shaped article 50 and the filler 120. Moreover, in this example, the buffer material 140 is installed in the storage container 100 so as to be in contact with the filler 120 from the outside, and is used to apply pressure to the filler 120. As the buffer material 140, a known buffer material used for packaging can be suitably used. More specifically, as the cushioning material 140, for example, a polyethylene cushioning material, a polyurethane foam cushioning material, a sponge, an air cushion, cotton, a rubber plate, or the like can be suitably used. The operation of applying pressure to the filler 120 with the buffer material 140 will be described in more detail below with reference to FIGS. 1B and 1C.

  FIG. 1B is a diagram for explaining the operation of housing the shaped object 50, the filler 120, and the buffer material 140 in the container 100. In this case, the operation of storing the modeled object 50 or the like in the storage container 100 is an example of the operation in the storage stage. Moreover, in this example, as shown in a figure, for example, the molded article 50 and the filler 120 are accommodated in the storage container 100 so that the periphery of the molded article 50 is surrounded by the filler 120. In this case, the surrounding of the modeled object 50 is surrounded by the filler 120, for example, when the modeled object 50 is buried in the filler 120, so that the entire periphery of the modeled object 50 is surrounded by the filler 120. It is. Moreover, in FIG.1 (b), the state in the storage container 100 is illustrated so that the modeling thing 50 can be seen by showing the cross section of the storage container 100 in which the modeling thing 50 is accommodated for convenience of illustration. Yes. However, at the time of actual packaging, for example, when the translucent storage container 100 is used, the storage container 100 is surrounded by the filler 120 so that the shaped object 50 cannot be seen from the outside of the storage container 100.

  Further, as described above, silica gel particles are used as the filler 120 in this example. In this case, for example, after filling the filler 120 from the bottom surface of the storage container 100 to a certain height by pouring the filler 120 into the storage container 100, the model 50 is placed thereon. And it is possible to add the filler 120 further from the top. In this case, it is preferable that the filler 120 is added sufficiently quietly after the modeling object 50 is installed so that the modeling object 50 is not damaged by the force of pouring the filler 120.

  Further, in this example, the buffer material 140 is installed on the filler 120 after the shaped article 50 and the filler 120 are accommodated in the container 100. Further, in this case, for example, as shown in the drawing, the cushioning material does not completely fit in the main body portion of the container 100 and at least a part of the cushioning material 140 protrudes from an opening portion that is later closed by the lid 106. 140 is installed. In the case of such a configuration, for example, by closing the lid 106 of the storage container 100, the cushioning material 140 sandwiched between the filler 120 and the lid 106 is pressed against the lid 106 and is filled from one direction. 120 will be pressed. As a result, pressure is applied to the filler 120 in the container 100.

  In addition, about the pressure applied at this time, it is possible to consider it as the intensity | strength which the molded article 50 does not move within the range of the impact force assumed at the time of transportation etc., for example. If comprised in this way, these positions can be fixed appropriately so that the molded article 50 and the filler 120 do not move even when the receiving container 100 receives an impact during transportation or the like. In order to apply such a pressure, it is conceivable that the buffer material 140 has a compressibility close to a solid. In addition, for example, in the case where a large amount of the filler 120 is placed in the container 100 and the lid 106 is closed, and the whole filler 120 is fixed using the elasticity (swelling) of the container 100 or the lid 106, the cushioning material 140 is provided. Even if it is not used, sufficient pressure can be applied to the filler. Therefore, in such a case, the cushioning material 140 may be omitted. Moreover, the reason for applying such pressure in this example is to appropriately fix the positions of the modeled object 50 and the filler 120 as described above. Therefore, for example, when using the filler 120 whose position is appropriately fixed without applying pressure, it is not necessary to apply pressure.

  FIG. 1C is a diagram illustrating a state in which the modeled object 50, the filler 120, and the buffer material 140 are accommodated in the accommodating container 100 and the lid 106 is closed. As described above, in this example, pressure is applied to the filler 120 by closing the lid 106 of the container 100 and sandwiching the cushioning material 140 between the filler 120 and the lid 106. In this case, the reaction force acts against the action of pressing the granular filler 120 with the buffer material 140, and the force to press the shaped object 50 surrounded by the filler 120 from all directions (all directions). Will occur. As a result, the positions of the filler 120 and the modeled object 50 are fixed in the storage container 100 and cannot move.

  In this case, the operation of fixing the positions of the filler 120 and the modeled object 50 in the storage container 100 is an example of the operation of the filler position fixing stage. The operation of the filler position fixing stage is, for example, an operation of preventing at least a part of the filler 120 in the storage container 100 from moving with respect to the modeled object 50. Further, in this case, the meaning that the filler 120 does not move with respect to the modeled object 50 is, for example, that the container 100 receives an impact of a predetermined size or less with respect to at least the filler 120 in contact with the modeled object 50. In such a case, it is necessary to prevent the model 50 from moving. In addition, with respect to the impact received by the storage container 100, the impact below a preset magnitude is, for example, an impact below the upper limit set according to the required impact resistance. Further, the upper limit impact is, for example, an impact assumed in accordance with a situation during transportation. The impact assumed according to the situation at the time of transportation is, for example, a standard impact or an impact corresponding to an inertial force received during transportation. In addition, the state in which the filler 120 does not move with respect to the modeled object 50 even when the container 100 receives an impact that is equal to or less than a preset magnitude is a large impact exceeding that (for example, an unexpected impact). In the case where it is received, the filler 120 and the shaped article 50 may move in the container 100. In addition, regarding the fact that the filler 120 does not move with respect to the modeled object 50 even when the container 100 receives an impact of a preset size or less, for example, at least when the container 100 is inclined to some extent It can be considered that the material 120 does not move. In this case, tilting the storage container 100 is, for example, tilting the storage container 100 compared to the timing when the filler 120 is filled. The degree to which the storage container 100 is tilted to some extent is, for example, a state in which the bottom surface of the storage container 100 is tilted by about 45 degrees with respect to the horizontal plane.

  Further, as described above, in this example, granular silica gel is used as the filler 120. Further, as the silica gel, a granular structure (silica gel particles) having a low fluidity property is used. In this case, it can be considered that the filling material 120 filled in the storage container 100 is in a state where pressure is evenly propagated in the storage container 100. The pressure propagates uniformly within the container 100 is not the same as, for example, the pressure propagation along a small number of limited paths, but is the same as or similar to the pressure propagation in the liquid due to the fluidity characteristics. Thus, the pressure is uniformly propagated in all directions in the container 100. In this case, when the cushioning material 140 is pressed against the filler 120 by the lid 106 and pressure is applied to the filler 120, the pressure is evenly propagated in the region filled with the filler 120 in the storage container 100, and the modeling is performed. The object 50 is pressed uniformly from all directions. Thereby, for example, it is possible to appropriately realize a state in which the filler 120 and the modeled object 50 do not easily move in the storage container 100. Moreover, about such a state, it can also be considered that the filler 120 becomes non-movable with respect to the molded article 50, for example. In this case, the operation of applying pressure to the filler 120 is considered to be, for example, an operation of fixing the relative position with respect to the molded object 50 in a state in which the filler 120 around the molded object 50 is in direct contact with the molded object 50. You can also Moreover, about such a state, the modeling thing 50 and the filler 120 are the inside of the container 100 by pressing the modeling object 50 uniformly from all directions with the filler 120, for example, and filling the surrounding space of the modeling object 50. It can also be thought of as a state that prevents moving with the.

  As described above, in this example, a container having a fixed shape that does not easily deform is used as the container 100 constituting the outer shell of the package. In this case, when the storage container 100 is transported or the like, partial movement (creep) of the modeled object 50 and the filler 120 that are the contents of the container 100 is more appropriately prevented, and the modeled object 50 and its surrounding state are prevented. Can be kept more appropriate in a certain state. Therefore, according to this example, it is possible to appropriately prevent the molded article 50 from being damaged even when the container 100 receives an impact during transportation or when it receives an inertial force accompanying transportation. . Further, in this case, since the filler 120 that exhibits fluidity is brought into close contact with the modeled object 50, the filler 120 and the modeled object 50 are configured not to move relatively. The shaped object 50 can be appropriately packed in the same procedure. In this case, the state where the filler 120 and the modeled object 50 do not move is a state where one of the filler 120 and the modeled object 50 does not move relative to the other. In this case, since the shaped object 50 can be appropriately packed without using a blister case for transportation or the like, the shaped object 50 having various shapes can be appropriately packed at low cost. Therefore, according to this example, it can pack appropriately in the state where it is hard to produce breakage with respect to modeling object 50 of various shapes modeled with a modeling device, for example.

  Further, the inventor of the present application actually uses a polypropylene container 100 and a silica gel filler 120 for a modeled object 50 modeled by a modeling apparatus that models using an ultraviolet curable ink by an inkjet method. The packaging in the state shown in FIG. 1 (c) was conducted, and an experiment was conducted in which the vehicle was transported at 500 km and stored for 10 days in a 60 ° C. environment. And in such an experiment, it confirmed that abnormality did not arise in the molded article 50 including damage, a deformation | transformation, discoloration, etc.

  Here, in the above description, the case where silica gel is mainly used for the filler 120 used for packing has been described. However, it is also conceivable to use various materials other than silica gel as the filler 120. For example, it is conceivable to use powder or granules of a desiccant other than silica gel as the filler 120. In this case, for example, it is conceivable to use powders or granules of a chemical desiccant such as calcium oxide or calcium chloride, or a physical desiccant such as aluminum oxide, zeolite, or molecular sieve. Also in this case, for example, by using the relatively inexpensive filler 120, the cost of the filler 120 can be appropriately reduced. In addition to the desiccant, a filler 120 made of various organic materials or inorganic materials can be used depending on conditions required at the time of packaging. More specifically, as such a filler 120, for example, potato starch can be suitably used. In addition, for example, flour or salt may be used. By using such powder or granules of food as the filler 120, for example, the highly safe filler 120 can be appropriately used. In addition to these, for example, an inorganic material such as sand may be used as the filler 120. In this case, for example, it is possible to use inexpensive and easily available sand such as commercially available river sand. In addition, powder or particles such as silica sand, iron sand, quicklime, magnesium sulfate, baked alum, sodium hydroxide, potassium carbonate, potassium hydroxide, anhydrous sodium sulfate, anhydrous copper sulfate, magnesium perchlorate, etc. are used as the filler 120. It can also be used as. Moreover, as the filler 120, it is also conceivable to use, for example, a powder commercially available as a gardening product. Also in this case, it is possible to use a filler 120 that is inexpensive and easily available. More specifically, as such a filler 120, for example, perlite, which is a foam powder (artificial foam) commercially available as gardening articles, or a powder commercially available as gardening articles, etc. It is conceivable to use some vermiculite or the like.

  Further, as the filler 120, for example, it is conceivable to use a resin. In this case, for example, the filler 120 can be appropriately reduced in weight. Thereby, for example, an increase in weight due to filling with the filler 120 can be appropriately suppressed. More specifically, in this case, for example, it is conceivable to use a foamed resin as the filler 120. Moreover, as such a filler 120, it is possible to use the particle | grains of resin foams, such as a polyurethane, a polystyrene, polyethylene, a polypropylene, or PET, for example. In this case, it is preferable to use non-charged resin foam particles. Further, for example, a hollow resin may be used as the resin filler 120. In this case, the hollow resin is, for example, a hollow pipe-shaped resin. As the hollow resin, for example, a hollow resin formed of polyethylene, polypropylene, PET, or the like can be suitably used. In this case, for example, the diameter is about 4 mm or less (for example, about 1 to 4 mm, preferably about 2 to 3 mm), and the length is 6 mm or less (for example, about 2 to 6 mm, preferably about 3 to 5 mm). It is conceivable to use hollow pipe-shaped particles. In this case, the thickness of the resin constituting the pipe is preferably about 0.1 mm (for example, about 0.05 to 2 mm). Further, the filler 120 is not limited to one type of filler 120, and a plurality of types of fillers 120 may be used in combination.

  Then, the modification etc. of the packing method of the molded article 50 are demonstrated. In the above, the case where mainly the surroundings of the shaped article 50 in the storage container 100 is filled only with the powder or granular filler 120 has been described. However, in a modified example of the packing method, a material other than the powder or granular filler 120 may be further used to fill the periphery of the shaped object 50 and the like. In this case, it is conceivable that at least a part of the space between the fillers 120 is further filled with a liquid in the operation of the storage stage in which the molded object 50 and the filler 120 are stored in the storage container 100. Such liquid filling is particularly preferably performed when, for example, a granular filler 120 is used. With this configuration, for example, even when a small gap is generated between the individual fillers 120 just by filling the filler 120 such as a granule, the gap can be appropriately filled with the liquid. Thereby, the movement of the contents of the storage container 100 can be prevented more appropriately.

  Here, when the liquid is filled in addition to the filler 120, if the amount of the liquid is too large, the contents of the storage container 100 may be easily moved. For this reason, the amount of the liquid is preferably set in a range in which the filler 120 is in a finely packed state only. The state of being densely packed only with the filler 120 is, for example, a state in which the filler 120 is finely packed in the container 100 even when the liquid is not filled. Moreover, about the method of filling with a liquid, it is preferable to fill with a liquid so that a liquid may arrive between the fillers 120 around the molded article 50, for example. As the liquid used in combination with the filler 120 in this way, a liquid having a specific gravity of 2 or more or a liquid having a viscosity of 0.04 Pa · s or more can be suitably used. Moreover, as such a liquid, it is possible to use glycerin, silicon oil, tetrabromoethane, etc., for example.

  In addition, when filling the container 120 with the filler 120 and the liquid, the timing of filling each of them may be, for example, filling the liquid after filling the filler 120 first. If comprised in this way, a liquid can be appropriately filled with the clearance gap between the fillers 120 used as the fine packing, for example. Further, depending on the shape of the molded object 50 to be packed and the conditions required for packing, for example, filling the filler 120 and the liquid at the same time may be considered. If comprised in this way, the filling material 120 and the liquid can be more uniformly filled into the container 100, for example. Further, for example, it is conceivable to fill the filler 120 after first filling a predetermined amount of liquid.

  Various changes can be made to the manner of filling the storage container 100 with the filler 120, the operation performed after the cover of the storage container 100 is closed, and the like. FIG. 2 is a diagram for explaining a modified example of the packing method. 2A to 2C show various modifications of the packing method. Except as described below, in FIG. 2, the configuration denoted by the same reference numeral as in FIG. 1 may have the same or similar features as the configuration in FIG. 1.

  In the above description, the cushioning material 140 used at the time of packing has been described mainly in a manner in which the cushioning material 140 is installed at a position in contact with the lid 106 of the storage container 100 as shown in FIGS. 1B and 1C, for example. However, the buffer material 140 may be installed in a location other than the position in contact with the lid 106 in the storage container 100. More specifically, in this case, for example, as shown in FIG. 2A, it is conceivable to install the buffer material 140 at a position in contact with the bottom surface or the side surface of the storage container 100. If comprised in this way, since the volume which should be filled with the filler 120 in the storage container 100 becomes small, the usage-amount of the filler 120 can be reduced, for example. In this case as well, at the portion of the container 100 in contact with the lid 106, for example, as shown on the left side in the figure, the buffering material 140 is protruded so that at least a part of the cushioning material 140 protrudes from the opening that is closed by the lid 106 later. The material 140 is installed. Also in this case, for example, by closing the lid 106 as shown on the right side in the figure, it is possible to appropriately apply pressure to the filler 120 in the container 100. Thereby, for example, it is possible to appropriately realize a state in which the filler 120 and the modeled object 50 do not easily move in the storage container 100.

  Further, when the cushioning material 140 is also installed at a position in contact with the bottom surface or the side surface of the storage container 100 in this way, it may be considered that the cushioning material 140 and the filling material 120 do not directly contact each other. More specifically, in this case, for example, as shown in FIG. 2B, it is conceivable to use a bag 200 that accommodates the shaped article 50 and the filler 120. As the bag 200, for example, a polyethylene bag or the like can be suitably used. In this case, for example, the bag 200 is installed in the storage container 100 from the opening of the storage container 100 in a state where the cushioning material 140 is installed at a position in contact with the bottom surface or side surface of the storage container 100. Further, in this case, it is conceivable that the filler 120 and the model 50 are placed in the bag 200 so that the model 50 is completely buried in the filler 120, and the opening of the bag 200 is closed with a tape or the like. . If comprised in this way, it can prevent appropriately that the filler 120 of a fine powder or a granule enters into the buffer material 140 etc., for example. Further, in this case, it is preferable that the operation of putting the model 50 or the filler 120 into the bag 200 is performed after the bag 200 is put in the storage container 100. If comprised in this way, the state after putting the molded article 50 and the filler 120 in the bag 200 can be maintained in the more stable state, for example.

  Further, in order to more reliably protect the molded article 50 from impacts during transportation, not only the filler 120 and the buffer material 140 are placed in the storage container 100 but also, for example, as shown in FIG. In addition, it is preferable to further install a cushioning material 320 around the container 100. More specifically, in this case, as shown in the drawing, multiple packaging is performed by further using, for example, an exterior member 300 and a buffer material 320 which are outer boxes covering the outside of the storage container 100. As the exterior member 300, for example, a cardboard box having a size that can accommodate the container 100 inside can be suitably used. In this case, the buffer material 320 is filled between the housing container 100 and the exterior member 300 in the same or similar manner as, for example, a packing material used in a known packing method. As the cushioning material 320, for example, a known packaging cushioning material such as a foaming material or a cushioning material can be suitably used. In this case, the operation of installing the container 100 and the buffer material 320 in the exterior member 300 is an example of the operation in the exterior stage. The operation in the exterior stage is, for example, an operation of covering the storage container 100 and the buffer material 320 with the exterior member 300 so that at least a part of the periphery of the storage container 100 is in contact with the buffer material 320. If comprised in this way, the damage of the molded article 50 by the impact in transportation, etc. can be prevented more appropriately, for example.

  Moreover, in the above, the example of the packing method was mainly demonstrated about the case where the filler 120 of a powder or a granule is used. However, it is also conceivable to use a configuration other than powder or granules as the filler. More specifically, in this case, for example, it is conceivable to use, as the filler, a substance that changes phase from a liquid state to a solid state during the packing operation.

  Drawing 3 is a figure explaining the further modification of a packing method. FIGS. 3A to 3C show the same items as FIGS. 1A to 1C with respect to the characteristics of this modification. Except as described below, in FIG. 3, the configuration given the same reference numerals as those in FIG. 1 or 2 may have the same or similar features as the configuration in FIG. 1 or FIG. 2. Further, the filler 160 used in the present modification may have the same or similar characteristics as the filler 120 described with reference to FIG. 1 or FIG. 2 except for the points described below.

  In this modification, as the filling material 160 filled in the storage container 100, a substance that changes in phase from a liquid state to a solid state during the packaging operation is used instead of powder or granules. In this case, the liquid state is, for example, a fluid state that can be poured into the container 100. In this case, the filler 160 is in a liquid state at the time when the container 100 is filled. More specifically, in the present modification, for example, as illustrated in FIG. 3A, the model 50 is packed using the storage container 100 and the filler 160. Further, in this case, for example, as shown in FIG. 3B, the filling material 160 in a liquid state is filled in the housing container 100, so that the periphery of the modeled object 50 is enclosed by the filling material 160. The molded object 50 and the filler 160 are accommodated in the container 100. Further, in this case, after the shaped article 50 and the filler 160 are accommodated in the accommodating container 100, the filler 160 is changed into a solid state by lowering the temperature of the filler 160, for example. Even in this case, it is appropriate that the molded object 50 and the filler 160 move in the container 100 by filling the container 100 in a solid state without a gap and surrounding the molded object 50. Can be prevented. Thereby, damage to modeling object 50 can be prevented appropriately.

  Here, as such a filler 160, for example, a substance that is in a liquid state at a temperature that does not affect the shaped object 50 and that maintains a solid state at the temperature during transportation of the shaped object 50 is used. Is preferred. In this case, the temperature in a range that does not affect the modeled object 50 is, for example, a temperature at which the modeled object 50 is not softened or altered. Moreover, the temperature at the time of transport of the molded article 50 is the temperature of the environment where the molded article 50 is stored at the time of transport, for example. In this case, considering the temperature inside the vehicle for transportation, etc., the temperature during transportation can be considered to be about 50 ° C. at the maximum, for example. Moreover, when transporting in a more stable environment, the temperature during transport can be considered to be about 30 ° C., for example. Further, for example, when the modeled object 50 is transported while being kept at a predetermined low temperature, the temperature can be considered as the temperature during transport. More specifically, as such a filler 160, for example, fats and oils can be suitably used. In this case, when the container 160 is filled with the filler 160, for example, the fat and oil used as the filler 160 is set to a temperature at which the container becomes a liquid, and the container 100 is filled. After that, the temperature of the oil / fat is lowered to a temperature at which the oil / fat becomes solid, thereby changing the phase of the oil / fat to a solid state. Moreover, as such fats and oils, it is possible to use edible fats and oils, such as lard and margarine, and various industrial fats and oils, for example.

  Subsequently, an experiment (transport test) conducted by the inventors of the present application will be described. FIG. 4 is a diagram for explaining an experiment conducted by the inventor of the present application. FIG. 4A is a diagram illustrating a transportation test performed in a packing form in which packing is performed using a powder filler 120. In addition, in said description performed using FIGS. 1-3, it simplified about one part and demonstrated about the packing method for convenience of illustration and description. In addition, the specific packing method described below is partly different from the method described above for the convenience of experiments. However, as will be apparent from the following description, the basic features relating to preventing damage to the shaped object 50 are the same as or similar to the method described above.

  More specifically, in this experiment, for example, as described with reference to FIG. 2B, a polyethylene bag 200 is used, and the molded article 50 is completely contained in the filler 120. The filler 120 and the shaped article 50 were put in the bag 200 so as to be buried. In addition, the opening of the bag 200 is closed with tape in order to prevent the filler 120 and the like from leaking to the outside through the gap in the opening of the bag 200. In this experiment, as the filler 120, starch powder, which is an example of a powdery substance, was used. The reason for using potato starch is that it is not harmful to the human body and is easy to dispose of after use.

  Further, as the buffer material, as shown in the figure, a plurality of buffer materials 140a and 140b were used. Among these, the buffer material 140a is a buffer material for uniformly applying pressure to the buffer material 140 in the bag 200, and is installed on the upper side of the bag 200 as shown in the drawing. As the cushioning material 140a, a polyethylene bubble cushioning material was used. The buffer material 140b is a buffer material used to reduce the amount of the filler 120 used by being installed in the storage container 100. A polyurethane foam cushioning material was used as the cushioning material 140b. Further, as shown in the drawing, the cushioning material 140b was installed on the lower side of the bag 200 in the container 100. Moreover, as the storage container 100, a general cardboard box was used.

  In addition, as described above, it is preferable to use a container having a fixed shape as the storage container 100. Therefore, as the storage container 100, it is more preferable to use a container formed of a harder material such as plastic, glass, metal, or wood. However, a cardboard box or the like can be used as the storage container 100 as described above as long as a certain shape can be appropriately maintained during transportation.

  Moreover, also when packing as shown to Fig.4 (a), the filler 120 in the bag 200 is pressed by the buffer material 140a by closing the lid | cover of the storage container 100. FIG. In this case, the reaction force against the action of the cushioning material 140a pressing the filler 120 acts to generate a force for the filler 120 around the molded article 50 to press the molded article 50 from all directions. As a result, the filler 120 does not move in the storage container 100, and as a result, the model 50 does not move. In addition, as described above, it is possible to appropriately realize a state in which the modeled object 50 is hardly damaged when the modeled object 50 is transported. In addition, the inventor of the present application actually uses the modeled object 50 of the figure having a fine structure such as a finger part or a hair shape, and performs packing in the state shown in FIG. Experiments were conducted with multiple transports. And it confirmed that it could transport appropriately, without damaging the molded article 50. FIG.

  In addition, the inventor of the present application further conducted a comparative experiment in which transportation is performed in a package in another state in order to more appropriately confirm the effect of the package in the state illustrated in FIG. FIG. 4B is a diagram for explaining this comparative experiment. In this comparative experiment, in the case shown in FIG. 4A, the buffer material 140c, which is a polyethylene bubble buffer material, is used for the portion filled with the filler material 120, and the molded article 50 is wrapped with the buffer material 140c. The modeled object 50 was protected. Moreover, it fixed so that the molded article 50 and the shock absorbing material 140c might not move by installing the shock absorbing material 140a which is a polyethylene bubble shock absorbing material on it.

  Also in this case, the modeled object 50 is wrapped with polyethylene bubble cushioning material (buffer material 140c) together with air. Thereby, the force which holds down the modeling thing 50 so that it may not move within the storage container 100, and the cushion effect of the shock absorbing material 140c can be acquired. However, in this case, such a reaction of force is generated by the model 50 itself. In this case, for example, if a force is applied to move the model 50 due to an impact during transportation of the model 50, the force may be applied to the model 50 in a concentrated manner. As a result, it is considered that fine structural parts and the like are easily damaged. Further, the inventors of the present application actually conducted an experiment in which the packaging in the state shown in FIG. And it confirmed that the damage of the molded article 50 was easy to generate | occur | produce compared with the case where it packs in the state shown to Fig.4 (a). Moreover, it has confirmed that there exists an effect which prevents the damage of the molded article 50 about packing by the state shown to Fig.4 (a) by this.

  Moreover, the inventor of this application further experimented about the case where various fillers 120 other than a starch starch are used. FIG. 5 shows the results of experiments conducted with various fillers 120. In this experiment, transportation tests and storage tests were performed using various fillers 120 as indicated by numbers 1 to 5 in the figure. In this transportation test, packing was carried out in the same or similar manner as described with reference to FIG. 4 except for the filler 120 used, and the vehicle was transported by 200 km. In the storage test, storage was performed for one month in an environment of 60 ° C. Moreover, the modeling object 50 of the shape of a doll (figure) was used as the object of packing. In addition, as a reference example for comparison with the case where packing is performed using the filler 120, packing is performed using a film pack as shown by reference numeral 6, and a transportation test and a storage test are performed.

  More specifically, the filler 120 indicated by reference numeral 1 in the drawing is a hollow resin. As the hollow resin, a pipe-shaped resin having a diameter of 4.5 mm, a length of 6 mm, and a thickness of the resin constituting the pipe was 0.1 mm. In this case, the specific gravity of the filler 120 is an extremely small value of about 0.05. For example, the specific gravity is such that the weight when one small cardboard box is filled is about 1 kg. Therefore, when such a filler 120 is used, an increase in weight due to filling of the filler 120 can be appropriately suppressed. Further, in this case, the filler 120 did not adhere to the shaped object 50 that is an object to be packed, and the operability was good. Moreover, the result of the transportation test was good and the result of the storage test was very good. In addition, pipes were not deformed even when stored for a long time in a storage test. In this case, the filler 120 can be reused. From the above results, it can be seen that the hollow resin can be suitably used as the filler 120.

  Moreover, the filler 120 shown with the number 2 is silica gel. As silica gel, silica gel marketed as a desiccant for dried flowers was used. In this case, the specific gravity is larger than that of the hollow resin. However, in this case as well, the operability during the packaging work was good. Moreover, the result of the transportation test was extremely good. Also, the result of the storage test was good although it was necessary to remove the filler 120 from the modeled object using a brush or the like. In this case, the filler 120 can be reused. From the above results, it can be seen that silica gel can also be suitably used as the filler 120. Further, as described above, the silica gel filler 120 has a larger specific gravity than the hollow resin, so that it can be used particularly suitably when the weight after packing is allowed to be increased to some extent. . Further, since silica gel has a dehumidifying function and has a characteristic that particles do not stick even under high temperature and high humidity, for example, it may be used by mixing with other fillers 120. In this case, for example, the deterioration of the shaped article 50 is suppressed even in a high-temperature and high-humidity environment in a state where pressure is applied during long-term transportation, and the filler 120 is prevented from adhering to the surface of the shaped article 50. be able to. In this case, the weight after packing can be further reduced.

  Moreover, the filler 120 shown with the numbers 3 and 4 is pearlite and vermiculite. As perlite and vermiculite, perlite and vermiculite, which are commercially available as gardening supplies, were used. In these cases, the specific gravity is reduced as in the case of the hollow resin. However, in these cases, since dust is generated and a mask is required during work, the operability is lower than that of a hollow resin or the like. However, also in this case, the result of the transportation test was good. Also, the results of the storage test were good for pearlite and generally good for vermiculite, although it was necessary to remove the filler 120 from the modeled object using a brush or the like. In this case, that the result of the storage test is generally good means that, for example, the shaped article 50 can be properly stored except when the required level is severe. From the above results, it can be seen that pearlite and vermiculite can also be suitably used as the filler 120. In addition, as described above, the pearlite and vermiculite filler 120 has a lower operability than a hollow resin or the like, so that it is particularly preferably used when it is not a problem to use a mask during work. Can do.

  Moreover, the filler 120 shown with the number 5 is river sand. As river sand, river sand commercially available as plasterer sand was used. In this case, the specific gravity is larger than that of the hollow resin. However, in this case as well, the operability during the packaging work was good. The results of the transportation test were generally good. In this case, the result of the transportation test being generally good means that the molded article 50 can be appropriately transported except when the fragile shaped article 50 is transported. Further, the results of the storage test were good although it was necessary to remove the filler 120 from the modeled object using a brush or the like. From the above results, it can be seen that river sand can also be suitably used as the filler 120. Moreover, about river sand, the result of a transport test is getting a little worse compared with the other fillers 120 as mentioned above. Moreover, when using river sand, the process etc. of drying before use are needed. On the other hand, river sand can be obtained at a lower price than other fillers 120. Therefore, the river sand can be used particularly suitably when the shaped object 50 or the like that is relatively difficult to break is packed at a low cost.

  Further, as described above, reference numeral 6 in the figure indicates a reference example in which packing is performed using a film pack. Also in this reference example. After wrapping the modeled object 50 with a film pack, the modeled object 50 was fixed by sandwiching it with urethane having a size of 14 × 22 × 4 cm. In this case, it can be considered that the specific gravity of the film pack is sufficiently small. However, when packing is performed using a film pack, the labor required for the operation increases, and the operability is lowered. Moreover, as shown in the drawing, in this case, the molded article 50 was damaged in the transportation test, and the molded article 50 was deformed in the storage test. More specifically, in this case, in the transportation test, the finger part of the doll used as the modeled object 50 was damaged. In the storage test, the doll's legs were deformed. By comparison with this reference example, it can be understood that, for example, in the case of using the various fillers 120 described above, packaging under a condition in which the molded article 50 is not easily damaged or deformed can be realized appropriately.

  The present invention can be suitably used for, for example, a method for packing a three-dimensional object.
