Description

Technical Field

[0001] The present invention relates to a packaging device for containing a fluid substance, particularly a fluid substance having a property of separating into a plurality of layers, and a method for stirring the fluid substance stored in the packaging device.

Background Art

[0002] Many fluid substances used as building materials such as paints are mainly composed of additives such as pigments, resins, solvents, and water repellents. Since these main components have oil and water mixed therein, the fluid substance placed in a container such as a one-can cannot be used immediately after separating into an oil layer and a water layer. Therefore, it is necessary to stir and mix the fluid substance immediately before use.

[0003] Conventionally, when stirring and mixing a fluid substance such as paint, it has been common practice to use a dedicated device as described in Patent Document 1 and Patent Document 2.

[0004] The device described in Patent Document 1 is a stirring device (1) configured such that a first frame (4) rotating around a first rotating shaft (3) and a second frame (6) rotating around a second rotating shaft (5) are connected to each other, and a one-can (P) is fixed to the second frame (6). The one-can (P) fixed to the second frame (6) moves (rotates) in various directions with a large amount of movement as the first frame (4) and the second frame (6) rotate around the first rotating shaft (3) and the second rotating shaft (5). Thereby, the fluid contained in the one-can (P) is preferably stirred.

[0005] The device described in Patent Document 2 is a stirrer (1) including a motor (6), a main body (2) that rotates by driving of the motor (6) and has an output shaft (spindle 16) that projects downward and is connected to a stirring shaft (3), and a handle (20) attached to the main body (2).

[0006] At the tip of the stirring shaft (3) of the stirrer (1), a blade (19) is attached, and the rotation of the motor (6) is transmitted to the blade (19) through the output shaft (spindle 16) and the stirring shaft (3). The blade (19) is inserted into a fluid substance such as paint contained in a container, and then the motor (6) is rotated. The rotation of the motor (6) is transmitted to the blade (19) through the output shaft (spindle 16) and the stirring shaft (3) as described above, and the fluid substance is preferably stirred by the rotation of the blade (19).

Summary of the Invention

Problems to be Solved by the Invention

[0008] However, in the stirring operation using the above-mentioned dedicated stirring device, a large amount of carbon dioxide is emitted during the manufacture and use of the device. In addition, a large amount of carbon dioxide is also emitted due to the human activities of the workers.

[0009] In addition, the stirring operation using the above-mentioned dedicated stirring device is a on-site operation that is carried out at the site where the fluid substance is actually used after transporting a one-drum can or the like to the site where the fluid substance is used, and is complicated.

[0010] The present invention was created in view of the above problems, and its main object is to provide a packaging material that enables stirring without using a dedicated stirring device, and a method for stirring a fluid substance stored in the packaging material, thereby suppressing the emission of carbon dioxide, which is strongly required to be reduced globally, and simplifying the stirring operation.

Means for Solving the Problems

[0011] The present invention is characterized by comprising a bag body filled with a fluid substance, a packaging body provided with a storage portion for storing the bag body, and a fluid substance stirring means for promoting the stirring of the fluid substance in the bag body by utilizing a force acting on at least a part of the bag body and the packaging body filled with the fluid substance during conveyance. According to the present invention, when the packaging equipment is being conveyed by a conveying means or the like, the fluid substance is stirred and mixed through the fluid substance stirring means. More specifically, inertial forces acting on the packaging equipment (packaging equipment including a bag body filled with a fluid substance and a packaging body for storing the bag body) during conveyance or the like, or movements such as rocking and vibration generated by forces input through a loading platform or the like on which the packaging equipment is placed (hereinafter, the movement generated due to the force acting on the packaging equipment during conveyance may also be simply referred to as "vibration" or "vibration or the like") are generated and / or increased through the fluid substance stirring means, and the fluid substance is automatically stirred and mixed (the stirring and mixing of the fluid substance are promoted). As a result, the operation of stirring the fluid substance again at the site becomes unnecessary, and the equipment for stirring is also unnecessary. From these facts, the emission of carbon dioxide can be suppressed, and the simplification of the stirring operation can be achieved.

[0012] In addition to the above features, the present invention is characterized in that the fluid substance stirring means is installed between the bottom surface of the storage portion of the packaging body and the bag body, and includes a bag body placement member installed in the storage portion of the packaging body for placing the bag body, and a swing placement member installed on the bottom surface of the storage portion of the packaging body for swingably placing the bag body placement member. According to the present invention, the bag body placement member can be easily and surely swung greatly. Thereby, when the packaging equipment is being conveyed by a conveying means or the like, the fluid substance in the bag body placed on the bag body placement member can be effectively stirred.

[0013] In addition to the above features, the present invention is characterized in that the swing placement member includes a swing support member for swingably supporting the center of the bag body placement member. According to the present invention, the bag body placement member can be easily and surely swung greatly. Thereby, when the packaging equipment is being conveyed by a conveying means or the like, the fluid substance in the bag placed on the bag body placement member can be effectively agitated.

[0014] Moreover, in addition to the above features, the present invention is characterized in that the swing placement member is configured to include an elastic member that swingably supports the bag body placement member. According to the present invention, the bag body placement member can be easily and surely swung greatly. Thereby, when the packaging equipment is being conveyed by a conveying means or the like, the fluid substance in the bag placed on the bag body placement member can be effectively agitated.

[0015] Moreover, in addition to the above features, the present invention is characterized in that the fluid substance agitation means is configured to include a fluid substance agitation convex portion that protrudes on the bottom surface of the storage portion of the package and pushes a part of the lower surface of the bag into the interior of the bag. According to the present invention, an internal intrusion portion that enters the bag can be formed by the fluid substance agitation convex portion, and thereby the disturbance of the flow of the fluid substance in the bag can be amplified. Thereby, when the packaging equipment is being conveyed by a conveying means or the like, the fluid substance can be effectively agitated.

[0016] Moreover, in addition to the above features, the present invention is characterized in that a cylindrical support frame body is installed at a position surrounding the periphery of the bag in the storage portion of the package, and the lower end side of the support frame body is locked to a guide groove provided on the bottom surface of the package, and the guide groove is formed with a gap from the inner periphery surrounding the bottom surface of the package. According to the present invention, since the support frame body is separated from the side wall portion of the package by a predetermined separation distance, for example, due to vibrations during conveyance transmitted from the conveying means to this packaging equipment (the bag filled with the fluid substance and the package housing the bag), the bag and the fluid substance inside it are likely to sway horizontally. Thereby, the fluid substance sways greatly and is agitated, and the oil and moisture constituting the fluid substance can be sufficiently mixed.

[0017] The present invention also provides a method for stirring a fluid substance stored in a packaging device, comprising: a filling step of preparing the above-described packaging device and filling a fluid substance into a bag body stored in the packaging device; a placing step of placing the packaging device on a conveying means; and a conveying and stirring step of moving the conveying means and using the force acting on at least a part of the packaging device during the movement to promote stirring of the fluid substance in the bag body by a fluid substance stirring means provided in the packaging device. According to the present invention, when the packaging device is being conveyed by the conveying means, the fluid substance is automatically stirred and mixed, so that the operation of stirring again at the site becomes unnecessary, and the device for stirring is also unnecessary. From these aspects, the emission of carbon dioxide can be suppressed, and the simplification of the stirring operation can be achieved.

Advantages of the Invention

[0018] According to the present invention, without using a dedicated stirring device, by transporting the packaging device, etc., the stirring and mixing of the fluid substance stored in the packaging device can be performed. Thereby, the emission of carbon dioxide can be suppressed, and the simplification of the stirring operation can be achieved.

[0020] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In the following description, “up (upward direction)” refers to the direction facing the storage part W side from the bottom wall part 40 of the package 10 described below, and “down (downward direction)” refers to the opposite direction. Also, “horizontal (direction)” refers to any direction within a plane perpendicular to the above “up (upward direction)” and “down (downward direction)”.

[0021] ≪First Embodiment≫ One of the preferred embodiments of the present invention, the packaging equipment 1A, will be described as the first embodiment with reference to FIGS. 1 to 8.

[0022] [Configuration of Packaging Equipment 1A] As shown in FIG. 1, the packaging equipment 1A includes a package 10, a support frame 50 accommodated inside the package 10, a bag 70 accommodated inside the support frame 50, and a fluid substance stirring means 100 installed inside the support frame 50 and below the bag 70.

[0023] [Package 10] The package 10 is a box-shaped functional element that accommodates the bag 70 inside and enables the transportation of the bag 70 to various places, and constitutes the outermost part of the packaging equipment 1A. As shown in FIG. 1, the package 10 is a rectangular parallelepiped with six faces. More specifically, it has a rectangular parallelepiped form including side wall parts 20 surrounding the front, rear, left, and right sides, an upper wall part 30 surrounding the upper side, and a bottom wall part 40 surrounding the lower side. The storage part W where the bag 70 and the like are accommodated is formed within the space defined by the side wall parts 20, the upper wall part 30, and the bottom wall part 40.

[0024] The side wall portion 20, the upper wall portion 30, and the bottom wall portion 40 are formed of a material that allows the package 10 to have a predetermined mechanical strength (tensile strength) and rigidity. In the present embodiment, they are each formed from a plate-shaped cardboard sheet. The side wall portion 20, the upper wall portion 30, and the bottom wall portion 40 made of cardboard sheets are connected via folding edges, and a cardboard box is formed by assembly. In addition to the cardboard sheet, a thin steel sheet made of steel, a stainless steel sheet, an aluminum sheet, a plastic sheet, or the like may also be used. Further, when the side wall portion 20, the upper wall portion 30, and the bottom wall portion 40 are configured as separate elements, different materials may be used for each other.

[0025] The side wall portion 20 that constitutes the side surface of the package 10 is formed by folding a single cardboard sheet into a square tube shape, thereby forming flat plate rectangular-shaped first side surface 21a, second side surface 21b, third side surface 21c, and fourth side surface 21d, respectively. The first side surface 21a and the second side surface 21b are in positions facing each other, and the third side surface 21c and the fourth side surface 21d are in positions facing each other. Note that the side wall portion 20 is not limited to this form and may be other various cylindrical shapes such as a cylindrical shape, a hexagonal tube shape, an octagonal tube shape, or the like.

[0026] The side wall portion 20 is provided with a hand-holding hole 22 that opens at a predetermined position above the first side surface 21a. Further, each of the second and third side surfaces 21b and 21c is also provided with hand-holding holes 23 and 25 that open at predetermined positions above them. Each of the hand-holding holes 22, 23, and 25 has a function as a handle by inserting a finger when transporting the package 10. Each of the hand-holding holes 22, 23, and 25 is formed as a substantially rectangular hole having a size that allows at least one human finger to be inserted so as to function as a handle, for example. The form (position, number, shape, and size) of each of the hand-holding holes 22, 23, and 25 can be variously changed.

[0027] The upper surface wall portion 30 that constitutes the upper surface of the packaging body 10 is configured to be openable and closable so that the bag body 70 can be easily taken in and out. In the present embodiment, the flat first upper surface 31a, the second upper surface 31b, the third upper surface 31c, and the fourth upper surface 31d are respectively connected to the first side surface 21a, the second side surface 21b, the third side surface 21c, and the fourth side surface 21d in a foldable manner. The connecting portions between the first upper surface 31a and the first side surface 21a, the second upper surface 31b and the second side surface 21b, the third upper surface 31c and the third side surface 21c, and the fourth upper surface 31d and the fourth side surface 21d are formed with creases, and thus are configured to enable repeated opening and closing easily. In addition, when the side surface wall portion 20 and the upper surface wall portion 30 are formed as separate bodies, they may be connected to each other via a connecting element such as a hinge.

[0028] The first upper surface 31a and the second upper surface 31b are located opposite to each other and are opened and closed in the manner of a double-leaf door with the connecting portions to the first side surface 21a and the second side surface 21b as rotation axes. Further, the third upper surface 31c and the fourth upper surface 31d are located opposite to each other and are opened and closed in the manner of a double-leaf door with the connecting portions to the third side surface 21c and the fourth side surface 21d as rotation axes.

[0029] The upper wall portion 30 is provided with a gap for protruding the pouring cylinder 72 provided in the bag body 70, which will be described later, toward the outside of the upper wall portion 30. In the present embodiment, an opening 32 is provided in the fourth upper surface 31d, and notch portions 33 and 34 are provided in the first upper surface 31a and the second upper surface 31b. The notch portions 33 and 34 are formed at positions communicating with the opening 32 when the upper wall portion 30 (the first upper surface 31a, the second upper surface 31b, the third upper surface 31c, and the fourth upper surface 31d) is in a closed state, and the above-mentioned gap is formed. Further, the upper wall portion 30 is provided with a finger hook for facilitating the transportation of the package 10 (packaging equipment 1A). In the present embodiment, a finger hook 35 is opened in the third upper surface 31c. This finger hook 35 is provided so as to be located above the hand-held hole 25 when the package 10 is assembled into a predetermined shape, for example. When manually transporting the package 10 (packaging equipment 1A), insert the thumb into this finger hook 35 and insert the fingers other than the thumb into the hand-held hole 25. Thereby, the package 10 (packaging equipment 1A) can be surely gripped using five fingers, and it is also possible to transport the package 10 (packaging equipment 1A) with one hand. Note that a plurality of finger hooks may be provided. For example, finger hooks disposed above the hand-held holes 22 and 23 when the package 10 is assembled into a predetermined shape may be provided respectively.

[0030] In the present embodiment, the bottom wall portion 40 constituting the lower surface of the package 10 is configured by foldably connecting a flat first lower surface 41a, a second lower surface 41b, a third lower surface 41c, and a fourth lower surface 41d to the first side surface 21a, the second side surface 21b, the third side surface 21c, and the fourth side surface 21d, respectively. Fold lines are formed at the connecting portions between the first lower surface 41a and the first side surface 21a, the second lower surface 41b and the second side surface 21b, the third lower surface 41c and the third side surface 21c, and the fourth lower surface 41d and the fourth side surface 21d, which facilitates closing the bottom surface. When the side wall portion 20 and the bottom wall portion 40 are made of separate bodies, they may be connected to each other via a connecting element such as a hinge.

[0031] The first lower surface 41a and the second lower surface 41b are in positions facing each other, and are opened and closed in the manner of a Kannon door with the connecting portion with the first side surface 21a and the second side surface 21b as the rotation axis. Also, the third lower surface 41c and the fourth lower surface 41d are in positions facing each other, and are opened and closed in the manner of a Kannon door with the connecting portion with the third side surface 21c and the fourth side surface 21d as the rotation axis.

[0032] The first lower surface 41a and the second lower surface 41b project a superimposition projecting portion 413a and a superimposition projecting portion 413b downward through a bending line 411a and a bending line 411b, respectively. The positions of the bending line 411a and the bending line 411b are the same as the positions of the lower sides of the third lower surface 41c and the fourth lower surface 41d, and when the first lower surface 41a and the second lower surface 41b are bent inward, the positions of the bending line 411a and the bending line 411b are substantially coincident positions.

[0033] At the center of the bending line 411a and the center of the bending line 411b, there are formed swing support member storage holes 415a and 415b each formed of a circular through-opening. The swing support member storage holes 415a and 415b are formed at positions bisected by the bending lines 411a and 411b, respectively. The swing support member storage hole 415a and the swing support member storage hole 415b have the same dimensions, and are formed with a diameter dimension slightly smaller than the diameter of the swing support member 120 described below or substantially the same diameter dimension.

[0034] [Support frame body 50] The support frame body 50 is a functional element that, by intervening between the packaging body 10 and the bag body 70, supports the bag body 70 filled with a fluid substance in a stable posture within the storage portion W of the packaging body 10 at a predetermined separation distance from the side wall portion 20 of the packaging body 10 while shaping the bag body 70 into a predetermined shape. In this embodiment, the support frame body 50 is formed of cardboard into a polygonal cylindrical body. The bag body 70 is housed within the storage portion W1 of the support frame body 50. At positions on the upper portion of the support frame body 50 that are 180° opposed to each other, there are formed hand-holding holes 51 each consisting of a pair of substantially rectangular parallelepiped-shaped through-holes. The basic form of the support frame body 50 is not limited to the above-described cylindrical body, and for example, it may be a pentagonal cylindrical body or a circular cylindrical body. This support frame body 50 also serves as a mixing chamber for mixing the fluid substance within the bag body 70.

[0035] [Bag body 70] The bag body 70 is a functional element that enables the content (fluid substance) to be filled in and out freely and stored in a sealed state for a long period of time. It is mainly composed of a bag main body portion 71 that houses the content (fluid substance) inside, one spout cylinder 72 that communicates the space inside and outside of the bag main body portion 71, and a lid 73 that closes the spout cylinder 72.

[0036] The bag main body portion 71 is a flexible bag-shaped component. In this embodiment, it is composed of a synthetic resin film and can be filled with a fluid substance inside to expand. The bag main body portion 71 has predetermined mechanical strength (especially tensile strength), heat resistance performance, and expansion and contraction performance (elasticity), and preferably, it is formed of a transparent material such as a resin material like polypropylene through which the enclosed content can be visually recognized from the outside. However, it is not necessarily limited to this material, and any material may be used as long as it has the above-described performance.

[0037] The pouring cylinder 72 and the lid 73 are functional elements that enable pouring a fluid substance such as paint, which is the content, into the inside of the bag body 71 or pouring out the fluid substance such as paint placed in the bag body 71 to the outside, and also enable maintaining the inside of the bag body 71 in a sealed state for a long period of time. The pouring cylinder 72 and the lid 73 are made of, for example, a resin material, and are detachably connected to each other by screwing a male screw formed on one side and a female screw formed on the other side, for example.

[0038] [Fluid Substance Stirring Means 100] The fluid substance stirring means 100 is a functional element that generates and / or increases the movement such as rocking and vibration caused by the force acting on the packaging equipment 1A (the packaging equipment 1A including the bag body 70 filled with the fluid substance and the package 10 housing the bag body 70) during transportation or the like, and stirs the fluid substance. It is configured with a bag body placement member 110 and a rocking support member 120. The bag body placement member 110 is a functional element that swingably places the bag body 70. For example, it is formed as a circular plate-shaped member having a size that can be swingably housed in the housing portion W1 of the support frame body 50. The shape of the bag body placement member 110 is not limited to a circle, and may be various other shapes and structures as long as it can place the bag body 70 and swing. In this embodiment, the bag body placement member 110 is configured using a cardboard plate, but other various materials such as synthetic resin plates may be used. The key is that it is a member having the strength to place the bag body 70 and swing. The rocking support member 120 is configured as a solid or hollow sphere made of, for example, synthetic resin, and is arranged at the center of the lower surface of the bag body placement member 110 on which the bag body 70 filled with the fluid substance is placed, thereby swingably supporting the bag body placement member 110. The rocking support member 120 can be said to be a rocking placement member that swingably places the bag body placement member 110 installed on the bottom surface of the housing portion W of the package 10. Incidentally, as will be described later, the rocking support member 120 is configured to be inserted into the rocking support member housing hole 415 formed in the bottom wall portion 40 of the package 10 (more specifically, the rocking support member housing hole 415 formed from a pair of rocking support member housing holes 415a and 415b). Instead of or in addition to this form, it may be configured to be arranged in a hole (not shown) formed in the bag body placement member 110. Further, the rocking support member 120 is not limited to the above form, and may be arbitrary as long as it can function as a rocking placement member. That is, in order for the bag body placement member 110 on which the bag body 70 filled with the fluid substance is placed to easily swing with slight vibration or the like, it may be in a form that contacts or is in linear contact with the bag body placement member 110 at two or fewer points, for example, a hemispherical body, a weight body, or a belt-like body. Furthermore, the rocking support member 120 may be made of a material other than synthetic resin such as paper.

[0039] 〔Assembly Method of Packaging Equipment 1A〕 An example of the assembly method of the packaging equipment 1A will be described. Here, it is assumed that the assembly starts from the bottom wall portion 40 of the package 10. First, the overlapping protrusions 413a of the first lower surface 41a and the overlapping protrusions 413b of the second lower surface 41b are folded outward (in the direction away from the storage portion W) at the portions of the folding lines 411a and 411b, respectively, and overlap on the outer surfaces of the first lower surface 41a and the second lower surface 41b. Next, the first and second lower surfaces 41a and 41b with the overlapping protrusions 413a and 413b folded back are each folded inward (in the direction toward the inside of the storage portion W, the same applies hereinafter) at the portions of the connection portions with the first and second side surfaces 21a and 21b.

[0040] FIG. 2 is a schematic perspective view showing the state of the package 10 at this time, and FIG. 3 is a schematic perspective view of the main part showing only the portions of the first and second lower surfaces 41a and 41b at this time. As shown in these figures, by folding the overlapping protrusions 413a and 413b, a pair of semicircular swing support member storage holes 415a and 415b are formed. By folding the first and second lower surfaces 41a and 41b and joining the portions of both folding lines 411a and 411b, a single circular swing support member storage hole 415 is formed. Also, as shown by the dotted line in FIG. 3, on the inner bottom surfaces (the surfaces that become the bottom surface of the storage portion W) of the first and second lower surfaces 41a and 41b, guide grooves 45 that are each semicircular and form a single annular recess when combined are formed in advance. The guide grooves 45 are for inserting the lower end side 53 (see FIG. 1) of the support frame body 50 to position the support frame body 50 inside the package 10. The guide grooves 45 are formed by compressing and molding or notching the first and second lower surfaces 41a and 41b made of cardboard. The guide grooves 45 are formed with a predetermined gap from the inner periphery (the connection portions of the first to fourth side surfaces 21a to 21d and the first to fourth lower surfaces 41a to 41d) surrounding the inner bottom surface of the storage portion W of the package 10.

[0041] Next, the third and fourth lower surfaces 41c and 41d shown in FIG. 2 are folded inward and overlapped on the lower surfaces of the first and second lower surfaces 41a and 41b, and then the joint sides (tip sides) of both are connected and fixed by an adhesive tape or a metal fitting to complete the bottom wall portion 40.

[0042] Next, from above the open storage portion W of the package 10 with the bottom wall portion 40 assembled, the support frame body 50 shown in FIG. 1 is stored. At this time, the lower end side 53 of the support frame body 50 is locked in the guide groove 45, whereby the outer surface of the support frame body 50 and the inner surfaces of the first to fourth side surfaces 21a to 21d face each other with a predetermined gap therebetween without contacting each other.

[0043] Next, the swing support member 120 is stored in the support frame body 50 from above the open storage portion W of the package 10 and inserted into the swing support member storage hole 415. Thereby, the swing support member 120 is positioned at the center of the upper surface of the bottom wall portion 40. Further, the bag body placement member 110 is inserted into the support frame body 50 and placed on the swing support member 120. Thereby, the center of the lower surface of the bag body placement member 110 is supported at one point by the swing support member 120, and it can swing and rotate freely in a 360° direction around the supported fulcrum.

[0044] Next, from above the open storage portion W of the package 10, the bag body 70 is stored in the storage portion W1 of the support frame body 50 as shown in FIG. 4. Next, as shown in FIG. 5, the first and second upper surfaces 31a and 31b are folded back inward, and further, the third and fourth upper surfaces 31c and 31d are folded back on the upper sides of the first and second upper surfaces 31a and 31b. At this time, the pouring tube 72 of the bag body 70 passes through the gap formed by the cutout portions 33 and 34 of the folded first and second upper surfaces 31a and 31b and the opening 32 provided in the fourth upper surface 31d. Then, the joint sides (tip sides) of the third and fourth upper surfaces 31c and 31d are connected and fixed by an adhesive tape or a metal fitting to complete the upper surface wall portion 30. Then, the lid 73 is screwed onto the upper end opening of the pouring tube 72 to close it. Thereby, the assembly of the packaging equipment 1A is completed.

[0045] FIG. 6 is a schematic longitudinal sectional view of the assembled packaging equipment 1A (for the sake of illustration, the cross-sectional portions are different for each part). Further, FIG. 7 is a partial enlarged sectional view showing an enlarged view of the vicinity of the swing support member 120 in FIG. 6. As shown in FIG. 6, the packaging equipment 1A is configured by installing a fluid substance stirring means 100 between the bottom surface (the upper surface of the bottom wall portion 40) of the storage portion W of the package 10 and the bag body 70. At this time, the bottom surface of the bag body 70 is placed on the bag body placement member 110 of the fluid substance stirring means 100. Further, since the lower end side 53 of the support frame body 50 is locked in the guide groove 45, the support frame body 50 and the bag body 70 stored in the storage portion W1 of the support frame body 50 are separated from the side wall portion 20 of the package 10 by a predetermined separation distance. As shown in FIG. 7, a part of the swing support member 120 is stored in the swing support member storage hole 415, and in a positioned state, the bag body placement member 110 is placed thereon. The swing support member storage hole 415 has the first lower surface 41a (the second lower surface 41b) and the overlapping protrusion 413a (the overlapping protrusion 413b) overlapping, so that the depth of the hole becomes deeper, and the swing support member 120 can be more reliably held in the swing support member storage hole 415.

[0046] It should be noted that the above assembly procedure is an example, and it goes without saying that other various different assembly procedures may be used for assembly (the same applies to each of the following embodiments).

[0047] 〔Usage method of the packaging equipment 1A〕 Next, an example of the usage method of the packaging equipment 1A will be described. First, remove the lid 73 from the pouring cylinder 72 and fill the fluid substance (fluid material) from its upper end opening, and then cover the lid 73 again to seal the bag body 70 (filling step). Here, paint is used as the fluid substance to be filled in this example.

[0048] Then, as shown in FIG. 21 for example, this packaging equipment 1A is placed on a conveying means TK such as a truck from a warehouse E1 (loading step), and is transported to a site E2 where the filled fluid substance is used (transport and agitation step). When the packaging equipment 1A is placed on the conveying means TK and transported, due to vibrations during transportation transmitted from the conveying means TK to the packaging equipment 1A (including acceleration, deceleration, etc., the same applies hereinafter), as indicated by arrow A in FIG. 8, the bag placement member 110 swings largely randomly around the point where it is supported by the swing support member 120. For this reason, the bag 70 placed on the bag placement member 110 also swings largely randomly. Furthermore, the bag placement member 110 may swing in the rotational direction so as to twist in the state where the bag 70 is placed around the swing support member 120. Thus, the bag 70 can be swung more effectively in the vertical direction and the rotational direction.

[0049] As a result, the fluid substance inside the bag 70 is also swung largely and agitated. For this reason, a fluid substance having a property of separating into an oil layer and a water layer when stationary, such as paint, is agitated and sufficiently mixed.

[0050] Furthermore, in this packaging equipment 1A, since the support frame 50 is separated from the side wall portion 20 of the package 10 by a predetermined distance, due to vibrations during transportation transmitted from the conveying means TK to the packaging equipment 1A, as indicated by arrow B in FIG. 8, the bag 70 and the fluid substance inside it are likely to swing horizontally. As a result, the fluid substance also swings largely and is agitated, and the oil component and the water component constituting the fluid substance are sufficiently mixed. This horizontal swing is amplified by the swing of the bag placement member 110. That is, due to the synergistic effect of both, the fluid substance swings more largely and is agitated.

[0051] When the packaging equipment 1A is unloaded at the site E2, there is no need to agitate the fluid substance again, and it can be used as it is.

[0052] 〔Effect of Packaging Equipment 1A〕 That is, when the packaging equipment 1A is being conveyed by the conveying means TK, the fluid substance is stirred and mixed through the fluid substance stirring means 100. More specifically, during conveyance or the like, the inertial force acting on the packaging equipment 1A (the packaging equipment 1A including the bag body 70 filled with the fluid substance and the packaging body 10 housing the bag body 70), or the force input through the loading platform or the like on which the packaging equipment 1A is placed, causes movements such as rocking and vibration. These movements are generated and / or increased through the fluid substance stirring means 100, and the fluid substance is automatically stirred and mixed (the stirring and mixing of the fluid substance are promoted). In particular, when the fluid substance stirring means 100 having the spherical rocking support member 120 functions, it rocks while changing its orientation in any direction within the horizontal plane, and the automatic stirring and mixing of the fluid substance are preferably performed. As a result, the operation of stirring the fluid substance again at the site becomes unnecessary, and the equipment for stirring is also unnecessary. From these facts, the emission of carbon dioxide can be suppressed, and the simplification of the stirring operation can be achieved. Furthermore, since materials such as cardboard that can be recycled easily and relatively inexpensively can be used, the emission of carbon dioxide associated with manufacturing can be significantly suppressed, and the manufacturing cost can also be reduced.

[0053] ≪Second Embodiment≫ One of the preferred embodiments of the present invention, the packaging equipment 1B, will be described as the second embodiment with reference to FIGS. 9 to 12.

[0054] 〔Configuration of Packaging Equipment 1B〕 In the packaging equipment 1B shown in FIGS. 9 to 12, the same or corresponding parts as those of the packaging equipment 1A according to the embodiment shown in FIGS. 1 to 8 are denoted by the same reference numerals. Matters other than those described below are the same as those in the embodiment shown in FIGS. 1 to 8.

[0055] In the packaging equipment 1B shown in FIGS. 9 to 12, the differences from the packaging equipment 1A shown in FIGS. 1 to 8 are only the structure of the bottom wall portion 40 of the packaging body 10 and the structure of the fluid substance stirring means 100. These structures will be mainly described below.

[0056] [Packaging Body 10] The package 10 in the packaging equipment 1B also has a rectangular parallelepiped shape including a side wall portion 20 surrounding the front, rear, left, and right sides, an upper wall portion 30 surrounding the upper side, and a bottom wall portion 40 surrounding the lower side. A storage portion W is formed inside thereof for accommodating a bag body 70 and the like.

[0057] The side wall portion 20 and the upper wall portion 30 have the same configuration as the packaging equipment 1A according to the first embodiment. In this embodiment, the bottom wall portion 40 is configured by connecting a flat first lower surface 41a, a second lower surface 41b, a third lower surface 41c, and a fourth lower surface 41d to the first side surface 21a, the second side surface 21b, the third side surface 21c, and the fourth side surface 21d, respectively, so as to be foldable. Folding lines are formed at the connecting portions between the first lower surface 41a and the first side surface 21a, the second lower surface 41b and the second side surface 21b, the third lower surface 41c and the third side surface 21c, and the fourth lower surface 41d and the fourth side surface 21d, which facilitates closing the bottom surface.

[0058] The bottom wall portion 40 of this packaging equipment 1A is not provided with the overlapping protrusions 413a and 413b provided in the packaging equipment 1A according to the first embodiment. That is, the positions of the lower edges of the first lower surface 41a and the second lower surface 41b are the same as the positions of the lower edges of the third lower surface 41c and the fourth lower surface 41d. When the first lower surface 41a and the second lower surface 41b are folded inward, the positions of their lower edges are substantially the same.

[0059] Oscillation support member storage recesses 417a and 417b each formed of a semi-circular recess are formed at the centers of the lower edges of the first lower surface 41a and the second lower surface 41b, respectively. The oscillation support member storage recesses 417a and 417b have the same dimensions and are formed with a diameter dimension slightly smaller than or substantially the same as the radius of the oscillation support member 120.

[0060] [Fluid substance stirring means 100] The fluid substance stirring means 100 used for the packaging equipment 1B according to the second embodiment includes, in addition to the same bag body placement member 110 and the swing support member (swing placement member) 120 used for the packaging equipment 1A according to the first embodiment, a plurality (four) of vibration assisting members 130.

[0061] The vibration assisting member 130 is an elastic body in the shape of a flat plate rectangle, and in this embodiment, urethane rubber having high resilience and high elasticity characteristics is used. The vibration assisting members 130 are installed at equal intervals (every 90 degrees) on the circumference centered on the position where the swing support member 120 is installed on the upper surface of the bottom wall portion 40. These vibration assisting members 130 may be attached when assembling the packaging equipment 1B, or may be attached in advance on the first lower surface 41 and the second lower surface 41b constituting the upper surface of the bottom wall portion 40, or may be attached in advance on the lower surface of the bag body placement member 110.

[0062] Note that as the vibration assisting member 130, a member having rubber elasticity made of a material other than urethane rubber may be used, or instead of the member having rubber elasticity, other elastic bodies such as a coil spring, a leaf spring, or a hollow rubber may be used.

[0063] 〔Assembly method of the packaging equipment 1B〕 An example of the assembly method of the packaging equipment 1B will be described. First, fold the first and second bottom surfaces 41a and 41b inward at the portions of the joints with the first and second side surfaces 21a and 21b, respectively. FIG. 10 is a schematic perspective view showing the state of the package 10 at this time. As shown in this figure, by folding the first and second bottom surfaces 41a and 41b and joining their tip sides together, a pair of semicircular rocking support member storage recesses 417a and 417b form a single circular rocking support member storage hole 417. Although not shown in FIG. 10, on the inner bottom surfaces of the first bottom surface 41a folded inward and the second bottom surface 41b, guide grooves 45 (see FIG. 11), similar to those shown by the dotted lines in FIG. 3, which are semicircular and form a single annular recess when combined, are formed in advance. This guide groove 45 is also formed with a predetermined gap from the inner periphery (the joint portions of the first to fourth side surfaces 21a to 21d and the first to fourth bottom surfaces 41a to 41d) surrounding the inner bottom surface of the storage portion W of the package 10.

[0064] Next, fold the third and fourth bottom surfaces 41c and 41d shown in FIG. 10 inward, superimpose them on the lower surface side of the first and second bottom surfaces 41a and 41b, and then connect and fix the portions of their joint sides (tip sides) with an adhesive tape or a metal fitting to complete the bottom wall portion 40.

[0065] Next, attach four vibration assisting members 130 to the first bottom surface 41 and the second bottom surface 41b which are the inner bottom surface of the package 10, for example, by a double-sided tape. The attachment positions are at equal intervals of 90° on the circumference centered on the rocking support member storage hole 417 inside the guide groove 45.

[0066] Then, in the same manner as in the case of the first embodiment, the support frame 50 is stored from above the open storage portion W of the package 10. Next, the rocking support member 120 is stored in the support frame 50 and inserted into the rocking support member storage hole 417. Next, the bag body placing member 110 is inserted into the support frame 50 and placed on the rocking support member 120. As a result, the bag body placing member 110 can rock and rotate freely in all directions of 360° by the rocking support member 120.

[0067] Next, the bag body 70 is stored in the storage part W1 of the support frame body 50 from above the open storage part W of the package 10. Next, the first and second upper surfaces 31a and 31b are folded back inward, and further, the third and fourth upper surfaces 31c and 31d are folded back on the upper sides of the first and second upper surfaces 31a and 31b. At this time, the pouring cylinder 72 of the bag body 70 penetrates through the gap formed by the notch parts 33 and 34 of the folded first and second upper surfaces 31a and 31b and the opening 32 provided on the fourth upper surface 31d. Then, the joint side parts of the third and fourth upper surfaces 31c and 31d are connected and fixed by an adhesive tape or a metal fitting to complete the upper surface wall part 30. And it is closed by screwing the lid 73 to the upper end opening of the pouring cylinder 72. Thus, the assembly of the packaging equipment 1B is completed.

[0068] FIG. 11 is a schematic longitudinal sectional view of the assembled packaging equipment 1B (for the convenience of illustration, the cross-sectional parts are different in each part). As shown in the figure, in the packaging equipment 1B, a fluid substance stirring means 100 is installed between the bottom surface (the upper surface of the bottom wall part 40) of the storage part W of the package 10 and the bag body 70, and the bottom surface of the bag body 70 is configured to be placed on the bag body placing member 110 of the fluid substance stirring means 100.

[0069] Also, since the lower end side 53 of the support frame body 50 is locked in the guide groove 45, the support frame body 50 and the bag body 70 stored in the storage part W1 of the support frame body 50 are separated by a predetermined distance from the inner surface of the side wall part 20 of the package 10. Further, as shown in FIG. 11, a part of the swing support member 120 is stored in the swing support member storage hole 417, and the bag body placing member 110 is placed thereon in a positioned state. Also, the upper surfaces of the respective vibration assisting members 130 are separated by a predetermined dimension from the lower surface of the bag body placing member 110.

[0070] 〔Usage method of the packaging equipment 1B〕 Next, an example of the usage method of the packaging equipment 1B will be described. First, the lid 73 is removed from the pouring cylinder 72, and a fluid substance (paint in this example) is filled from its upper end opening, and then the lid 73 is put on again to seal the bag body 70.

[0071] Then, as shown in FIG. 21, for example, this packaging equipment 1B is placed on a conveying means TK such as a truck from a warehouse E1 and transported to a site E2 where a filled fluid substance is used. When the packaging equipment 1B is placed on the conveying means TK and transported, due to vibrations during transportation (including acceleration and deceleration) transmitted from the conveying means TK to the packaging equipment 1B, as shown by arrow A in FIG. 12, the bag placement member 110 swings randomly and greatly around the point where it is supported by the swing support member 120. Therefore, the bag 70 placed on the bag placement member 110 also swings randomly and greatly. In this packaging equipment 1B, since a vibration assisting member 130 is further installed, when the lower surface of the swung swing support member 120 comes into contact with the upper surface of the vibration assisting member 130, the elastic force thereof can push the swing support member 120 back in the opposite direction, thereby generating a more effective swinging action.

[0072] As a result, the fluid substance inside the bag 70 also swings greatly and is agitated. Therefore, a fluid substance having a property of separating into an oil layer and a water layer when stationary, such as paint, is agitated and sufficiently mixed.

[0073] Furthermore, also in this packaging equipment 1B, similar to the first embodiment, due to vibrations during transportation (including acceleration and deceleration) transmitted from the conveying means TK to the packaging equipment 1B, as shown by arrow B in FIG. 12, the bag 70 and the fluid substance inside it are likely to sway horizontally. As a result, the fluid substance also sways greatly and is agitated, and the oil component and the water component constituting the fluid substance are sufficiently mixed. This horizontal sway is amplified by the swaying of the bag placement member 110. That is, due to the synergistic effect of both, the fluid substance sways and is agitated even more greatly.

[0074] When the packaging equipment 1B arrives at the site E2 and is unloaded, there is no need to agitate the fluid substance again, and it can be used as it is.

[0075] 〔Effect of Packaging Equipment 1B〕 As described above, also in the packaging equipment 1B, when being conveyed by the conveying means TK as in the case of the packaging equipment 1A, the fluid substance is automatically stirred and mixed. In particular, when the fluid substance stirring means 100 including the vibration assisting member 130 functions, more suitable rocking occurs and effective automatic stirring and mixing are performed. As a result, the work of stirring the fluid substance again at the site becomes unnecessary, and the equipment for stirring also becomes unnecessary. From these facts, the emission of carbon dioxide can be suppressed, and the simplification of the stirring work can be achieved. Furthermore, since materials such as cardboard that can be recycled easily and relatively inexpensively can be used, the emission of carbon dioxide associated with manufacturing can be suppressed to a small extent, and the manufacturing cost can also be suppressed.

[0076] ≪Third Embodiment≫ One of the preferred embodiments of the present invention, the packaging equipment 1C, will be described as the third embodiment with reference to FIGS. 13 to 14.

[0077] 〔Configuration of Packaging Equipment 1C〕 FIG. 13 is a schematic longitudinal sectional view of the assembled packaging equipment 1C (for convenience of illustration, the cross-sectional portions are different for each part). In the packaging equipment 1C shown in FIG. 13, the same reference numerals are given to the same or corresponding parts as those of the packaging equipment 1A and 1B according to the embodiments shown in FIGS. 1 to 12. Matters other than those described below are the same as those of the embodiments shown in FIGS. 1 to 12.

[0078] In the packaging equipment 1C shown in FIG. 13, the differences from the packaging equipment 1A and 1B shown in FIGS. 1 to 12 are only the structure of the bottom wall portion 40 of the package 10 and the structure of the fluid substance stirring means 100. These structures will be mainly described below.

[0079] [Package 10] In the package 10 of the packaging equipment 1C, the first, second, third, and fourth lower surfaces 41a, 41b, 41c, and 41d that constitute the bottom wall portion 40 are all rectangular flat plates, and the overlapping protrusions 413a and 413b, the swing support member storage holes 415a and 415b provided in the packaging equipment 1A, and the swing support member storage recesses 417a and 417b provided in the packaging equipment 1B are not provided.

[0080] [Fluid substance stirring means 100] The fluid substance stirring means 100 used for the packaging equipment 1C according to the third embodiment is configured to include a plurality (five) of elastic members 140 in addition to the same bag placement member 110 as that used for the packaging equipment 1A and 1B according to the first and second embodiments.

[0081] The elastic member 140 is an elastic body (elastic body) made of a spring, and one is installed at the central position on the upper surface of the bottom wall portion 40, and four are installed at equal intervals (90 degrees each) on the circumference centered on the central position. The bag placement member 110 can swing by the elastic member 140.

[0082] Note that as the elastic member 140, instead of the spring, other various elastic bodies such as the vibration assisting member 130 made of urethane rubber used in the second embodiment, a leaf spring, or a hollow rubber may be used.

[0083] [Usage method of the packaging equipment 1C] Next, an example of the usage method of the packaging equipment 1C will be described. First, remove the lid 73 from the pouring cylinder 72 and fill the fluid substance (paint in this example) from its upper end opening, then put the lid 73 back on to seal the bag 70. Then, place this packaging equipment 1C on a transport means TK such as a truck as shown in FIG. 21, for example, and transport it to the site E2 where the filled fluid substance is to be used. When the packaging equipment 1C is placed on the transport means TK and transported, due to the vibration during transportation transmitted from the transport means TK to the packaging equipment 1C, as shown by the arrow A in FIG. 14, the bag placement member 110 swings greatly randomly as the lengths of the respective elastic members 140 change, and for this reason, the bottom surface of the bag 70 placed on the bag placement member 110 also swings greatly randomly.

[0084] As a result, the fluid substance inside the bag body 70 is also greatly shaken and agitated. Therefore, a fluid substance such as paint, which has the property of separating into an oil layer and a water layer when stationary, is agitated and thoroughly mixed.

[0085] Furthermore, also in this packaging equipment 1C, similar to the above-described first and second embodiments, due to vibrations during conveyance transmitted from the conveyance means TK to the packaging equipment 1C, as indicated by the arrow B in FIG. 14, the bag body 70 and the fluid substance inside thereof are likely to sway in the horizontal direction. As a result, the fluid substance is also greatly shaken and agitated, and the oil component and the water component constituting the fluid substance are thoroughly mixed. This horizontal sway is amplified by the swaying of the bag body placement member 110. That is, due to the synergistic effect of both, the fluid substance sways and is agitated even more greatly.

[0086] When the packaging equipment 1C is lowered at the site E2, there is no need to agitate the fluid substance again, and it can be used as it is.

[0087] 〔Effect of Packaging Equipment 1C〕 As described above, also in the packaging equipment 1C, similar to the above-described packaging equipment 1A and 1B, when being conveyed by the conveyance means TK, the fluid substance is automatically agitated and mixed. As a result, the operation of agitating the fluid substance again at the site becomes unnecessary, and the equipment for agitation also becomes unnecessary. From these facts, the emission of carbon dioxide can be suppressed, and the simplification of the agitation operation can be achieved. Furthermore, since materials such as cardboard that can be recycled easily and relatively inexpensively can be used, the emission of carbon dioxide associated with manufacturing can be reduced, and the manufacturing cost can also be suppressed.

[0088] ≪Fourth Embodiment≫ A packaging equipment 1D, which is one of the preferred embodiments of the present invention, will be described as the fourth embodiment with reference to FIG. 15.

[0089] 〔Configuration of Packaging Equipment 1D〕 FIG. 15 is a schematic longitudinal sectional view of the assembled packaging equipment 1D (for the sake of illustration, the cross-sectional portions are different for each part). In the packaging equipment 1D shown in FIG. 15, the same or corresponding parts as those of the packaging equipment 1A and 1B according to the embodiments shown in FIGS. 1 to 12 are denoted by the same reference numerals. Note that matters other than those described below are the same as those of the embodiments shown in FIGS. 1 to 12.

[0090] In the packaging equipment 1D shown in FIG. 15, the differences from the packaging equipment 1A and 1B shown in FIGS. 1 to 12 are only the structure of the bottom wall portion 40 of the package 10 and the structure of the fluid substance stirring means 100. These structures will be mainly described below.

[0091] [Package 10] In the package 10 of the packaging equipment 1D, similar to the bottom wall portion 40 of the package 10 in the packaging equipment 1C, the first, second, third, and fourth lower surfaces 41a, 41b, 41c, and 41d constituting the bottom wall portion 40 are all rectangular flat plates, and the overlapping protrusions 413a and 413b, the swing support member storage holes 415a and 415b provided in the packaging equipment 1A, and the swing support member storage recesses 417a and 417b provided in the packaging equipment 1B are not provided.

[0092] [Fluid Substance Stirring Means 100] The fluid substance stirring means 100 used in the packaging equipment 1D according to the fourth embodiment includes, in addition to the same bag body placement member 110 as that used in the packaging equipment 1A and 1B according to the first and second embodiments, a swing support member 150 attached to the lower surface of the bag body placement member 110.

[0093] The swing support member 150 is formed of, for example, a synthetic resin molded product that protrudes downward. The upper surface of the swing support member 150 is flat, and the lower surface is spherical. The upper surface is fixed to the center of the lower surface of the bag body placement member 110 by adhesion or the like.

[0094] [Method of Using Packaging Equipment 1D] Next, an example of the usage method of the packaging equipment 1D will be described. The packaging equipment 1D filled with a fluid substance (paint in this example) in the bag body 70 and sealed is placed on a conveying means TK such as a truck from a warehouse E1, as shown in FIG. 21 for example, and transported to a site E2 where the filled fluid substance is to be used. When the packaging equipment 1D is placed on the conveying means TK and transported, due to vibrations during transportation transmitted from the conveying means TK to the packaging equipment 1D, the bag body placing member 110 supported at one point by the swing support member 150 swings greatly randomly. For this reason, the bottom surface of the bag body 70 placed on the bag body placing member 110 also swings greatly randomly.

[0095] As a result, the fluid substance inside the bag body 70 is also greatly swung and agitated. For this reason, a fluid substance having a property of separating into an oil layer and a water layer when stationary, such as paint, is agitated and sufficiently mixed.

[0096] Furthermore, also in this packaging equipment 1D, similar to the first, second, and third embodiments, due to vibrations during transportation transmitted from the conveying means to the packaging equipment 1D, the bag body 70 and the fluid substance inside it are likely to swing in the horizontal direction. As a result, the fluid substance also swings greatly and is agitated, and the oil component and the water component constituting the fluid substance are sufficiently mixed. This horizontal swing is amplified by the swing of the bag body placing member 110. That is, due to the synergistic effect of both, the fluid substance swings and is agitated even more greatly.

[0097] And when the packaging equipment 1D is unloaded at the site E2, there is no need to agitate the fluid substance again, and it can be used as it is.

[0098] 〔Effect of the packaging equipment 1D〕 As described above, also in the packaging equipment 1D, similarly to the above-described packaging equipment 1A, 1B, and 1C, when being conveyed by the conveying means TK, the fluid substance is automatically stirred and mixed. As a result, the work of stirring the fluid substance again at the site becomes unnecessary, and the equipment for stirring is also unnecessary. From these facts, the emission of carbon dioxide can be suppressed, and the simplification of the stirring work can be achieved. Furthermore, since materials such as cardboard that can be recycled easily and relatively inexpensively can be used, the emission of carbon dioxide associated with manufacturing can be significantly suppressed, and the manufacturing cost can also be reduced.

[0099] ≪Fifth Embodiment≫ One of the preferred embodiments of the present invention, the packaging equipment 1E, will be described as the fifth embodiment with reference to FIGS. 16 to 20.

[0100] [Configuration of Packaging Equipment 1E] In the packaging equipment 1E shown in FIGS. 16 to 20, the same or corresponding parts as those of the packaging equipment 1A to 1D according to the embodiments shown in FIGS. 1 to 15 are denoted by the same reference numerals. Regarding matters other than those described below, they are the same as those of the embodiments shown in FIGS. 1 to 15.

[0101] In the packaging equipment 1E shown in FIGS. 16 to 20, the difference from the packaging equipment 1A to 1D shown in FIGS. 1 to 15 is only that the fluid substance stirring means 100 is provided on the bottom wall portion 40 of the package 10 itself. This structure will be mainly described below.

[0102] [Package 10 and Fluid Substance Stirring Means 100] Also in the package 10 of this packaging equipment 1E, it has the same side wall portions 20 and upper surface wall portion 30 as those shown in the above-described packaging equipment 1A to 1D. The bottom wall portion 40 is configured in this embodiment by foldably connecting a flat first lower surface 41a, a second lower surface 41b, a third lower surface 41c, and a fourth lower surface 41d to the first side surface 21a, the second side surface 21b, the third side surface 21c, and the fourth side surface 21d, respectively.

[0103] The first lower surface 41a and the second lower surface 41b that constitute the bottom wall portion 40 of the packaging equipment 1E respectively project downward a fluid substance stirring convex portion 419a and a fluid substance stirring convex portion 419b via a folding line 418a and a folding line 418b. The positions of the folding line 418a and the folding line 418b are the same as the positions of the lower sides of the third lower surface 41c and the fourth lower surface 41d, and when the first lower surface 41a and the second lower surface 41b are folded inward, the positions of the folding line 418a and the folding line 418b are substantially coincident. The fluid substance stirring convex portion 419a and the fluid substance stirring convex portion 419b are in a rectangular strip shape, and their horizontal lengths are shorter than the lengths of the lower sides of the first lower surface 41a and the second lower surface 41b, and are formed at the centers of these lower sides. These fluid substance stirring convex portions 419a and 419b together constitute the fluid substance stirring means 100.

[0104] Note that the fluid substance stirring convex portions 419a and 419b that constitute the fluid substance stirring means 100 are not limited to the above form, and any form may be used as long as it protrudes from the bottom wall portion 40. For example, a plurality of fluid substance stirring convex portions in a rectangular strip shape may be arranged spaced apart and parallel to each other, or may be arranged so as to intersect each other, or one or a plurality of fluid substance stirring convex portions in a dot shape may be arranged so as to protrude from the bottom wall portion 40.

[0105] 〔Assembly method of packaging equipment 1E〕 An example of the assembly method of the packaging equipment 1E will be described. First, with the fluidity substance stirring protrusions 419a and 419b each bent inward at the portions of the folding lines 418a and 418b, the first bottom surface 41a and the second bottom surface 41b are each folded back inward at the portions of the connection parts with the first and second side surfaces 21a and 21b. FIG. 17 is a schematic perspective view showing the state of the packaging body 10 at this time, and FIG. 18 is a schematic perspective view of the main part showing only the portions of the first and second bottom surfaces 41a and 41b at this time. As shown in these figures, when the first and second side surfaces 21a and 21b are folded back, the fluidity substance stirring protrusions 419a and 419b are joined to form one fluidity substance stirring means 100, and protrude upright from the inner bottom surfaces of the first and second bottom surfaces 41a and 41b toward the inside of the storage part W.

[0106] Also, in the case of this embodiment, as shown by the dotted line in FIG. 18, guide grooves 45, which are each semi-circular and form one annular concave portion when combined, are pre-formed on the inner bottom surfaces of the first and second bottom surfaces 41a and 41b.

[0107] Next, the third and fourth bottom surfaces 41c and 41d shown in FIG. 17 are folded back inward, superimposed under the first and second bottom surfaces 41a and 41b, and then the portions of their joint sides (tip sides) are connected and fixed by an adhesive tape or a metal fitting to complete the bottom wall portion 40.

[0108] Then, the support frame body 50 is stored from above the open storage part W of the packaging body 10. Next, the bag body 70 is stored in the storage part W1 of the support frame body 50. Next, the first and second upper surfaces 31a and 31b are folded back inward, and further the third and fourth upper surfaces 31c and 31d are folded back inward and fixed. Then, the lid 73 is screwed to the upper end opening of the pouring cylinder 72 to close it. Thus, the assembly of the packaging equipment 1E is completed.

[0109] FIG. 19 is a schematic longitudinal sectional view of the assembled packaging device 1E (for the sake of illustration, the cross-sectional parts are different for each part). As shown in the figure, in the packaging device 1E, a fluid substance stirring means 100 is installed between the bottom surface of the storage part W of the package 10 (the upper surface of the bottom wall part 40) and the bag body 70. The fluid substance stirring means 100 is provided protruding on the bottom surface of the storage part W of the package 10 and pushing a part (central part) of the lower surface of the bag body 70 into the inside of the bag body 70. An internal intrusion part 75 is formed on the lower surface of the bag body 70 pushed into the inside.

[0110] 〔Usage method of the packaging device 1E〕 Next, an example of the usage method of the packaging device 1E will be described. First, remove the lid 73 from the pouring cylinder 72 and fill it with a fluid substance (in this example, paint) from its upper end opening, and then put the lid 73 back on to seal the bag body 70.

[0111] Then, place this packaging device 1E on a conveying means TK such as a truck as shown in FIG. 21, for example, and transport it to the site E2 where the filled fluid substance is to be used. When the packaging device 1E is placed on the conveying means TK and conveyed, due to vibrations during conveyance transmitted from the conveying means TK to the packaging device 1E, etc., the fluid substance creates a flow moving inside the bag body 70, but when this flow crosses the internal intrusion part 75 formed on the lower surface of the bag body 70, it is disrupted as shown by the arrow C in FIG. 20.

[0112] By thus disrupting the flow of the fluid substance inside the bag body 70, the stirring action of the fluid substance also increases. For this reason, a fluid substance having a property of separating into an oil layer and a water layer when stationary, such as paint, is more effectively stirred and mixed.

[0113] Furthermore, also in this packaging equipment 1E, similar to the first to fourth embodiments described above, due to vibrations during conveyance transmitted from the conveyance means TK to the packaging equipment 1E, as indicated by the arrow B in FIG. 20, the bag body 70 and the fluid substance inside it are likely to sway horizontally. Also due to this, the fluid substance sways greatly and is agitated, and the oil and moisture components that make up the fluid substance are sufficiently mixed. This horizontal sway is amplified by the disturbance of the flow of the fluid substance caused by the internal intrusion portion 75. That is, due to the synergistic effect of both, the fluid substance sways and agitates even more greatly.

[0114] And when the packaging equipment 1E is lowered at the site E2, there is no need to agitate the fluid substance again, and it can be used as it is.

[0115] 〔Effect of Packaging Equipment 1E〕 As described above, also in the packaging equipment 1E, similar to the packaging equipment 1A to 1D, the fluid substance is automatically agitated and mixed when being conveyed by the conveyance means TK. As a result, the operation of agitating the fluid substance again at the site becomes unnecessary, and the equipment for agitation is also unnecessary. For these reasons, the emission of carbon dioxide can be suppressed, and the simplification of the agitation operation can be achieved. Furthermore, since materials such as cardboard that can be recycled easily and relatively inexpensively can be used, the emission of carbon dioxide associated with manufacturing can be significantly suppressed, and the manufacturing cost can also be reduced.

[0116] ≪Other Embodiments (Variations)≫ In the packaging equipment 1A according to the first embodiment to the packaging equipment 1E according to the fifth embodiment, in each case, the fluid substance stirring means 100 is disposed within the storage portion W, which is the internal space of the package 10, and more specifically, between the bottom surface of the storage portion W and the bag body 70. As a modification of these embodiments, for example, an external fluid substance stirring means 200 (at least one of the external fluid substance stirring means 200A to 200G described later) may be disposed outside the package 10. This external fluid substance stirring means 200 may be an alternative to the fluid substance stirring means 100 disposed within the storage portion W, or may be an addition to the fluid substance stirring means 100.

[0117] FIG. 22 is a view showing a packaging equipment 1A' including the packaging equipment 1A according to the first embodiment further provided with an external fluid substance stirring means 200A. More specifically, it is a view showing a packaging equipment 1A' in which the external fluid substance stirring means 200A is disposed outside the package 10 constituting the packaging equipment 1A. That is, the packaging equipment 1A' includes the fluid substance stirring means 100 disposed inside the package 10 and the external fluid substance stirring means 200A disposed outside the package 10. Note that the fluid substance stirring means 100 may not be disposed inside the package 10, and the external fluid substance stirring means 200A may be disposed only outside the package 10.

[0118] The external fluid substance stirring means 200A includes at least a package placement member 210 on which the package 10 is placed on the upper surface and a swing support member 220 provided on the lower surface of the package placement member 210.

[0119] The package placement member 210 is a functional element for swingably supporting the package 10 that houses the bag body 70 filled with the fluid substance. That is, although there is a difference in whether the package placement member 210 directly places the bag body 70 filled with the fluid substance or places it via the package 10, it is an element common to the bag body placement members 110 according to the first to fourth embodiments in the main function of swingably placing a heavy object. The package placement member 210 is configured as a flat plate member formed so that the shape in plan view is the same as that of the package 10 or wider than that of the package 10.

[0120] The package placement member 210 may be provided with a structure for preventing the package 10 from falling off the package placement member 210 even when the package 10 swings violently. For example, it includes a retaining wall 211 as the structure. This retaining wall 211 is protruded along the outer peripheral edge of the package placement member 210 so that the planar shape formed by the inner surface is complementary to the planar shape of the lower part of the package 10 in plan view. An accommodation space H in which the lower part of the package 10 is arranged is formed inside the retaining wall 211. The retaining wall 211 receives the reaction force of the force (such as inertial force) acting on the package 10 when the package 10 that houses the bag body 70 filled with the fluid substance swings violently. For this reason, it is desirable that each dimension (height, thickness, contact area with the package 10, etc.) of the retaining wall 211 be set so as to withstand the reaction force. For example, each dimension may be set in consideration of the vertical swing range of the package 10, the weight of the package 10 that houses the bag body 70 filled with the fluid substance, and the position of the center of gravity. In the packaging equipment 1A' shown in FIG. 22, between the packaging equipment 1A and the externally attached fluid substance stirring means 200A, more specifically, between the lower surface of the package 10 and the upper surface of the package placement member 210, an optional element, a friction member M with a large static friction coefficient, is disposed.

[0121] The structure for preventing the package body 10 from falling off the package body placement member 210 is not necessarily limited to the form of the holding wall 211, and can be arbitrary as long as the relative movement between the package body 10 and the package body placement member 210 in the horizontal plane is restricted and they are detachable. For example, concave and convex portions having complementary shapes to each other may be arranged in a pair on at least a part of two opposing surfaces, that is, at least a part of the outer surface of the bottom wall portion 40 of the package body 10 and at least a part of the upper surface of the package body placement member 210.

[0122] It is desirable that the form such as the material and shape of the package body placement member 210 be set so as to have rigidity and strength such that it does not deform even when the package body 10 filled with the fluid substance is placed thereon. Further, in the package body placement member 210 provided with the holding wall 211, it is preferable that the form such as the material and shape be set so as to have strength and rigidity such that it does not deform or break due to the force input from the package body 10 (for example, the reaction force of the inertial force acting on the package body 10) even when the package body 10 filled with the fluid substance swings violently. For example, it is useful to form the package body placement member 210 from a metal or polymer material (synthetic resin) having high mechanical property values such as tensile strength and Young's modulus, and to increase the rigidity by appropriately providing ribs or the like. In addition, when forming the package body placement member 210 from paper (such as cardboard) having relatively inferior mechanical property values, it is useful to use a honeycomb structure.

[0123] Note that the bottom wall portion 40 of the package body 10 and the package body placement member 210 may be integrally formed. For example, the bottom wall portion 40 of the package body 10 may be configured to also serve as the package body placement member 210. In this integrally formed form, a structure for preventing the package body 10 such as the holding wall 211 from falling off the package body placement member 210 becomes unnecessary.

[0124] On the lower surface of the package placement member 210, a swing support member 220 is provided. This swing support member 220 is an element having the same main functions as the swing support member 120 according to the first and second embodiments, and the swing support member 150 according to the fourth embodiment. That is, the swing support member 220 is a functional element for swinging the package 10 placed on the package placement member 210 by using forces such as inertial forces acting on the package 10 and the bag body 70 filled with a fluid substance accommodated therein. The swing support member 220 is formed, for example, as a hemispherical body protruding downward from the center of the lower surface of the package placement member 210. More specifically, it is configured as a molded product of synthetic resin having the same form as the swing support member 150, that is, a flat upper surface and a spherical lower surface, and the upper surface is fixed to the center of the lower surface of the package placement member 210 by adhesion or the like. Thereby, the package placement member 210 is supported by contacting the swing support member 220 and a part of its own lower surface against the loading platform of the conveying means TK or the like. Note that the form of the swing support member 220 may be arbitrary as long as it can swingably support the package placement member 210 on which the package 10 accommodating the bag body 70 filled with a fluid substance is placed. That is, the swing support member 220 provided on the lower surface of the package placement member 210 may be formed to contact the loading platform of the conveying means TK or the like at two points or less, or to contact the loading platform of the conveying means TK or the like in a single straight line. For example, it may be in the form of a weight body or a column body extending on a horizontal plane (for example, a column body having a semicircular or triangular vertical cross-sectional shape). Also, it may be made of corrugated paper, metal, or carbon fiber instead of synthetic resin.

[0125] According to the packaging equipment 1A' provided with the above-described external fluid substance stirring means 200A, when a force such as an inertial force or a vibration-induced force acts on the packaging equipment 1A (the packaging equipment 1A including the bag body 70 filled with the fluid substance and the packaging body 10 storing the bag body 70) during transportation or the like, the packaging body placing member 210 on which the packaging equipment 1A (packaging body 10) is placed swings while changing its orientation in an arbitrary direction within the horizontal plane around the swing support member 220. The above fluid substance is automatically stirred and mixed by this swinging. This automatic stirring becomes more desirable due to a synergistic effect with the automatic stirring (the automatic stirring brought about by the packaging equipment 1A) brought about by disposing the fluid substance stirring means 100A inside the packaging body 10.

[0126] FIG. 23 is a diagram showing an external fluid substance stirring means 200B in which a placing member 215 is added to the external fluid substance stirring means 200A. The placing member 215 is a member arranged so as to be interposed between the lower surface of the packaging body placing member 210 and between the swing support member 220 and the loading platform of the conveying means TK or the like. For example, it is configured as a flat plate-shaped member whose planar shape is complementary to that of the packaging body placing member 210. The packaging body placing member 210 and the swing support member 220 are prevented from directly contacting the loading platform of the conveying means TK or the like by the arrangement of the placing member 215 and are preferably protected from breakage and wear.

[0127] A recess 215a having a shape complementary to that of the swing support member 220 may be arbitrarily provided in a portion of the placement member 215 that faces the swing support member 220. This recess 215a has, for example, a shape complementary to a portion (the lower part of the swing support member 220) including the contact portion (pressure contact portion) of the swing support member 220, and is formed such that the vertical dimension = depth is smaller than the vertical dimension = height of the swing support member 220. Thereby, the recess 215a is configured such that its entire inner side abuts (pressure contacts) the swing support member 220. In another example, the depth and the shape of the opening edge are formed such that the swing support member 220 abuts (pressure contacts) at the opening edge. The recess 215a in this form serves to hold the swing support member 220 in a predetermined position. By this function, the package placement member 210 with the swing support member 220 fixed thereto, and the packaging equipment 1A (package 10) placed on the package placement member 210 are restricted from moving in the horizontal direction. As a result, the package placement member 210 on which the packaging equipment 1A (the packaging equipment 1A including the bag body 70 filled with the fluid substance and the package 10 housing the bag body 70) is placed remains in a predetermined position without falling off the placement member 215 even when it swings violently. As a result, safe transportation is realized, and the energy consumption associated with relative movement is preferably suppressed, so that agitation of the fluid substance during transportation can be performed with high efficiency (in a form excellent in energy efficiency).

[0128] In addition, a low-friction element for reducing the contact resistance between each other may be provided on the surface of the recess 215a and / or the surface of the swing support member 220. The low-friction element may be a coating agent or the like made of a fluororesin or the like. By providing the low-friction element, the swing of the package placement member 210 with the swing support member 220 fixed thereto with respect to the placement member 215 becomes more suitable (large with a small force).

[0129] The placement member 215 abuts (presses) with a predetermined pressure (specifically, the pressure resulting from the weight of the package 10 that houses the bag body 70 filled with the fluid substance) while relatively moving (rotating relatively) with respect to the swing support member 220, and also abuts (presses) with a predetermined impact force against the lower surface of the package placement member 210. For this reason, it is desirable that the placement member 215 be formed from a material that can withstand the above-described predetermined pressure (surface pressure) and impact force.

[0130] In the placement member 215, an element that restricts relative movement, for example, a friction member having a large coefficient of static friction, may be optionally provided on the contact surface with the loading platform of the conveying means TK or the like. Thereby, even if the packaging equipment 1A (the packaging equipment 1A including the bag body 70 filled with the fluid substance and the package 10 that houses the bag body 70) swings violently, the relative movement of the external fluid substance agitation means 200B with respect to the loading platform of the conveying means TK on which it is placed is preferably restricted. By restricting the relative movement, safe conveyance is realized, and since the energy consumption associated with the relative movement is preferably suppressed, agitation during conveyance or the like can be performed with high efficiency (in a form excellent in energy efficiency).

[0131] Note that a connecting element 225 that connects the package placement member 210 and the placement member 215 may be disposed between them so that relative movement (relative swing centered on the swing support member 220) between the package placement member 210 and the placement member 215 becomes possible. The connecting element 225 is composed of, for example, a coil spring having a small spring constant or a bellows-shaped member, and is configured such that its upper end is joined to the lower surface of the package placement member 210 and its lower end is joined to the upper surface of the placement member 215. The connecting element 225 may be one or a plurality. In the case of one, it may be configured as a telescopic cylindrical member that houses the swing support member 220 inside. By providing the connecting element 225, the elements constituting the external fluid substance agitation means 200B are integrated, and thereby, the handling of the external fluid substance agitation means 200B becomes easy.

[0132] According to the packaging equipment 1A' provided with the external fluid substance stirring means 200B, in addition to the same effects as the packaging equipment 1A' provided with the external fluid substance stirring means 200A, an effect is brought about that the swing support member 220 is preferably protected from breakage and wear and the durability is improved. Further, when the external fluid substance stirring means 200B includes the concave portion 215a and / or the friction member, effects such as the realization of safe conveyance as described above and the realization of automatic stirring excellent in energy efficiency are brought about.

[0133] The external fluid substance stirring means 200C shown in FIG. 24 is an embodiment in which a vibration assisting member 230 is additionally disposed between the package placing member 210 and the placing member 215 with respect to the external fluid substance stirring means 200B. The vibration assisting member 230 is, for example, a member having high resilience and high elasticity, such as urethane rubber, other members having rubber elasticity, or other elastic bodies such as a coil spring, a leaf spring, or a hollow rubber, in the same manner as the vibration assisting member 130 in the second embodiment, and the upper surface is separated from the lower surface of the package placing member 210 by a predetermined dimension. In FIG. 24, a vibration assisting member 230 made of urethane rubber is exemplarily shown. The arrangement of the vibration assisting member 230 in plan view is not limited to a specific one. For example, a total of four vibration assisting members 230, one each in front of and behind the swing support member 220 and one each on the left and right, are arranged at point-symmetrical positions centered on the swing support member 220. Note that the connecting element 225 may be optionally disposed.

[0134] According to the packaging equipment 1A' provided with the external fluid substance stirring means 200C, in addition to the same effects as the packaging equipment 1A' provided with the external fluid substance stirring means 200B, the swinging action is preferably amplified by the strong elastic force of the vibration assisting member 230, and the automatic stirring becomes more suitable.

[0135] The externally attached fluid substance stirring means 200D shown in Fig. 25 is a reconfigured version of the externally attached fluid substance stirring means 200C as follows. That is, the swing support member 220 that was protrudingly provided (fixed) on the lower surface of the package placement member 210 of the externally attached fluid substance stirring means 200C is reconfigured to protrudingly provide (fix) the swing support member 220' on the upper surface of the placement member 215'. Also, the recess 215a provided in the placement member 215 of the externally attached fluid substance stirring means 200C is reconfigured to provide a recess 210'a on the lower surface of the package placement member 210'. Here, the vibration assisting member 230 may be optionally arranged, and the connecting element 225 may be optionally arranged. (Fig. 25 illustratively shows the externally attached fluid substance stirring means 200D with the vibration assisting member 230 and the connecting element 225 arranged). Further, a low friction element for reducing the mutual contact resistance may be provided on the surface of the recess 210'a and / or the surface of the swing support member 220'. The low friction element may be a coating agent made of fluororesin or the like. By providing the low friction element, the swing of the package placement member 210' with respect to the placement member 215' to which the swing support member 220' is fixed becomes more suitable (large with a small force).

[0136] Furthermore, the bottom wall portion 40 of the package 10 and the package placement member 210' may be integrally formed. For example, the bottom wall portion 40 of the package 10 may be configured to also serve as the package placement member 210'. In this case, the recess 210'a may be formed by applying the form of the swing support member storage hole 417 in the first embodiment described above. That is, the swing support member storage hole 417 was formed by swing support member storage recesses 417a and 417b, which are a pair of semi-circular recesses provided on the first and second lower surfaces 41a and 41b forming the inside of the bottom wall portion 40. However, this may be formed as the recess 210'a by swing support member storage recesses 417c and 417d (not shown), which are a pair of semi-circular recesses provided on the third and fourth lower surfaces 41c and 41d forming the outside of the bottom wall portion 40.

[0137] The externally attached fluid substance stirring means 200E shown in Fig. 26 is formed by combining the placement member 215 having the recess 215a in the externally attached fluid substance stirring means 200B and the package placement member 210' having the recess 210'a in the externally attached fluid substance stirring means 200D, and disposing a swing support member 220'' between the recess 210'a and the recess 215a. The swing support member 220'' is a member configured to be rotatable relative to the package placement member 210' and the placement member 215, and has, for example, substantially the same form as the swing support member 120 according to the first and second embodiments, that is, a form such as a solid or hollow sphere made of synthetic resin. Note that the form of the swing support member 220'' is not limited to a solid or hollow sphere made of synthetic resin, and any form may be used as long as it can support the package 10 containing the bag body 70 filled with the fluid substance and is rotatable relative to the package placement member 210' and the placement member 215. For example, it may be made of cardboard, metal, or carbon fiber, and its shape may be, for example, a cylindrical shape with a circular vertical cross section.

[0138] Similar to the externally attached fluid substance stirring means 200D, a vibration assisting member 230 may be optionally disposed, and a connecting element 225 may be optionally disposed (Fig. 26 exemplarily shows the externally attached fluid substance stirring means 200E with the vibration assisting member 230 and the connecting element 225 disposed). Further, low friction elements for reducing the mutual contact resistance may be provided on the surface of the recess 210'a and / or the swing support member 220'' and / or the surface of the recess 215a. The low friction element may be a coating agent made of a fluororesin or the like. By providing the low friction element, the swing of the package placement member 210' relative to the placement member 215 via the swing support member 220'' becomes more suitable (large with a small force). Note that, similar to the externally attached fluid substance stirring means 200E, the bottom wall portion 40 of the package 10 and the package placement member 210' may be integrally formed.

[0139] The external fluid substance stirring means 200F shown in Fig. 27 is an embodiment in which an elastic member 240 is disposed between a package placement member 210'' and a placement member 215''. The elastic member 240 is composed of an elastic body (elastic member) made of a spring, for example, similar to the elastic member 140 in the packaging equipment 1C according to the third embodiment. One elastic member 240 is provided at the central position, and four elastic members 240 are installed at equal intervals (90 degrees each) on the circumference centered on the central position. Here, the elastic member 240 is not limited to a specific one as long as it is a functional element that can generate and / or increase motions such as rocking and vibration caused by inertial forces acting on the packaging equipment (a bag filled with a fluid substance and a package containing the bag) during transportation and the like, or forces input through a loading platform on which the packaging equipment is placed. Also, the arrangement of the elastic member 240 may be arbitrary as long as the stability is maintained such that the rocking package 10 does not fall off the external fluid substance stirring means 200F. Similar to the package placement member 210 in the fluid substance stirring means 200C and the package placement member 210'' in the fluid substance stirring means 200D, the package placement member 210'' may be integrally formed with the bottom wall portion 40 of the package 10. For example, the bottom wall portion 40 of the package 10 may also serve as the package placement member 210''.

[0140] The externally attached fluid substance stirring means 200G shown in FIG. 28 is a fluid substance stirring means in which the accommodation space H is expanded so that a plurality of packaging materials 1A' (package 10) can be placed on the fluid substance stirring means 200F. Specifically, the accommodation space H formed in the package placement member 210'' of the fluid substance stirring means 200F is expanded to, for example, a package placement member 210''' in which three packaging materials 1A' (package 10) can be placed, and a placement member 215''' in which the horizontal area of the placement member 215'' is expanded according to the size of the package placement member 210'''. A fluid substance stirring means is provided with, for example, an elastic member 240 interposed between the package placement member 210''' and the placement member 215'''. Note that the elastic member 240 may be changed to a swing support member 220, a swing support member 220', or a swing support member 220'', the package placement member 210''' may be changed to a package placement member 210 or 210' in which the accommodation space H is expanded, and the placement member 215''' may be changed to a placement member 215, 215' in which the horizontal area is expanded.

[0141] Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications are possible within the scope of the technical idea described in the claims, the specification, and the drawings. Even if there is no description in the specification and the drawings regarding any shape, structure, or material, as long as the functions and effects of the present invention are achieved, it is within the scope of the technical idea of the present invention. Also, as long as there is no contradiction in the purpose and configuration, etc., the embodiments described above and shown in the respective figures can be combined with each other's description content. Further, even if it is a part of the above description and the description content of each figure, each can be an independent embodiment, and the embodiment of the present invention is not limited to one embodiment combining the above description and each figure.

[0142] For example, with respect to the components / members having common functions between the fluid substance stirring means 100 disposed inside the package 10 and the externally attached fluid substance stirring means 200 (externally attached fluid substance stirring means 200A to 200G) described as a modified example, since they are based on the same technical concept, they can be made compatible in terms of shape, structure, configuration, material, etc. while appropriately adjusting dimensions and the like. That is, the bag placement members 110 and the package placement members 210, 210', 210'' which are common in the main function of swingably placing heavy objects can be made compatible in the above forms. For example, a recess equivalent to the recess 210'a provided in the package placement member 210' may be provided in a portion of the bag placement member 110 facing the swing support member 120. Also, since the main functions of the swing support members 120 and 220 are common, they can be made compatible in the above forms. Further, the bottom wall portion 40 of the package 10 configured to abut (press-contact) with the swing support member 120 and the placement members 215, 215', 215'' configured to abut (press-contact) with the swing support member 220 can also be made compatible in the above forms because their functions are partially common.

[0143] Also, cardboard may be used as the fluid substance stirring means. Here, general cardboard is mainly composed of a front liner, a back liner, and a corrugated core interposed between these liners, and flutes (steps) are formed by the interposition of the core. The cardboard having the flutes (steps) has structural resilience, and this resilience can be utilized as that of the fluid substance stirring means. In particular, cardboard with a relatively large core height (thickness), for example, cardboard of the A flute standard with a core height (thickness) of 5 mm, or cardboard of the W flute standard with laminated cores, has a resilience suitable for use as the fluid substance stirring means. The fluid substance stirring means made of cardboard is disposed, for example, inside and / or outside the package 10. Further, by forming at least a part of the bottom of the package (for example, the bottom wall portion 40 of the package 10) with cardboard of the above standard, the package and the fluid substance stirring means may be configured to be integrated. FIG. 29 is a view showing that the fluid substance stirring means 200 is configured by disposing a W flute standard cardboard 250 composed of a front liner 251, a back liner 252, and a core 253 outside the package 10. The fluid substance stirring means 200 (cardboard 250) may be detachably disposed under the bottom wall portion 40 of the package 10 or fixed to the bottom wall portion 40 using an adhesive or the like. The fixing form is not limited to a specific form as long as the relative movement in the horizontal plane between the package 10 (the bag body 70 filled with the fluid substance and the package 10 storing the bag body 70) and the fluid substance stirring means 200 (cardboard 250) can be restricted. For example, similar to the form of restricting the relative movement in the horizontal plane between the package 10 and the package placing member 210, it may be a form in which a friction material having a large static friction coefficient or concave and convex portions having complementary shapes are provided on at least a part of two opposing surfaces.
