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-gallon can separates into an oil layer and a water layer and cannot be used immediately. Therefore, it is necessary to stir and mix the fluid substance immediately before use.

[0003] Conventionally, when stirring and mixing fluid substances such as paints, 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-gallon can (P) is fixed to the second frame (6). The one-gallon 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-gallon can (P) is suitably stirred.

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

[0006] A blade (19) is attached to the tip of the stirring shaft (3) of the stirrer (1), 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 placed in a container, and then the motor (6) is rotated. As described above, the rotation of the motor (6) is transmitted to the blade (19) through the output shaft (spindle 16) and the stirring shaft (3), and the fluid substance is suitably stirred by the rotation of the blade (19).

[0007] [Patent Document 1] Japanese Patent Publication No. 2005-52737 [Patent Document 2] Japanese Patent Publication No. 2023-73873 [Overview of the project] [Problems that the invention aims to solve]

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

[0009] Furthermore, the stirring process using the aforementioned dedicated stirring device was a cumbersome on-site operation, requiring the fluid material to be transported to the actual site of use (e.g., in large containers) and then carried out at that site.

[0010] This invention was created in view of the above-mentioned problems, and its main purpose is to provide packaging material that enables stirring without the use of a dedicated stirring device, and a method for stirring fluid substances contained within the packaging material, thereby suppressing carbon dioxide emissions, which are strongly needed to be reduced worldwide, and simplifying stirring operations. [Means for solving the problem]

[0011] The present invention comprises a bag for filling with a fluid substance, a packaging body having a storage section for housing the bag, and a fluid substance stirring means for promoting the stirring of the fluid substance inside the bag by utilizing the force acting on at least a part of the bag and the packaging body filled with the fluid substance during transport. 、 Equipped with The fluid material stirring means comprises a bag support member installed between the bottom surface of the storage section of the packaging body and the bag body, and installed inside the storage section of the packaging body on which the bag body is placed, and a swinging support member installed on the bottom surface of the storage section of the packaging body on which the bag support member is swingably supported. It is characterized by the following. According to the present invention, when packaging materials are being transported by a transport means, the fluid material is stirred and mixed through a fluid material stirring means. More specifically, during transport, motions such as swaying and vibration (hereinafter, motions caused by the forces acting on the packaging materials during transport, etc., including bags filled with fluid material and a packaging body that houses these bags) are generated and / or amplified through the fluid material stirring means, causing the fluid material to be automatically stirred and mixed (stirring and mixing of the fluid material is promoted). As a result, the work of stirring the fluid material again on site is eliminated, and equipment for stirring is also eliminated. Therefore, carbon dioxide emissions can be suppressed, and stirring work can be simplified.

[0012] Also According to the present invention, the bag support member can be easily and reliably shaken significantly. This allows for effective agitation of the fluid material inside the bag placed on the bag support member when the packaging material is being transported by a transport means.

[0013] Furthermore, in addition to the above features, the present invention is characterized in that the swingable mounting member is configured to include a swingable support member that swingably supports the center of the bag mounting member. According to the present invention, the bag support member can be easily and reliably shaken significantly. This allows for effective agitation of the fluid material inside the bag placed on the bag support member when the packaging material is being transported by a transport means.

[0014] Furthermore, in addition to the above features, the present invention is characterized in that the swingable mounting member is configured to include an elastic member that swingably supports the bag mounting member. According to the present invention, the bag support member can be easily and reliably shaken significantly. This allows for effective agitation of the fluid material inside the bag placed on the bag support member when the packaging material is being transported by a transport means.

[0016] In addition to the above features, the present invention is further characterized in that a cylindrical support frame is installed at a position surrounding the bag body within the storage section of the packaging body, the lower end of the support frame is locked into a guide groove provided on the bottom surface of the packaging body, and the guide groove is formed with a gap from the inner periphery surrounding the bottom surface of the packaging body. According to the present invention, since the support frame is separated from the side wall of the packaging body by a predetermined distance, the bag and the fluid substance inside it are more likely to shake horizontally due to vibrations transmitted to the packaging equipment (the bag filled with the fluid substance and the packaging body that houses the bag) from the conveying means, for example. As a result, the fluid substance shakes and is stirred, and the oil and water that make up the fluid substance can be thoroughly mixed.

[0017] The present invention also relates to a method for stirring a fluid substance stored in packaging equipment, characterized by comprising: a filling step of preparing the above-mentioned packaging equipment and filling a bag body stored in the packaging equipment with a fluid substance; a placement step of placing the packaging equipment on a transport means; and a transport and stirring step of moving the transport means and using the force acting on at least a part of the packaging equipment during the movement to promote stirring of the fluid substance inside the bag body by a fluid substance stirring means provided in the packaging equipment. According to the present invention, since the fluid substance is automatically agitated and mixed while the packaging material is being transported by the transport means, there is no need for further agitation work on-site, and no equipment for agitation is required. As a result, carbon dioxide emissions can be reduced and the agitation work can be simplified. [Effects of the Invention]

[0018] According to the present invention, without using a dedicated stirring device, by transporting packaging materials or the like, the fluid substances stored in the packaging materials can be stirred and mixed. As a result, the emission of carbon dioxide can be suppressed, and the stirring operation can be simplified.

[0020] Preferred embodiments of the present invention will be described in detail below with reference to the drawings. In the following explanation, "up" refers to the direction from the bottom wall portion 40 of the packaging body 10 toward the storage portion W, and "down" refers to the opposite direction. Furthermore, "horizontal" refers to any direction in a plane perpendicular to the above-mentioned "up" and "down".

[0021] ≪First Embodiment≫ A packaging material 1A, which is one of the preferred embodiments of the present invention, will be described as a first embodiment with reference to Figures 1 to 8.

[0022] [Composition of Packaging Equipment 1A] As shown in Figure 1, the packaging equipment 1A comprises a packaging body 10, a support frame 50 housed inside the packaging body 10, a bag 70 housed inside the support frame 50, and a fluid substance stirring means 100 installed inside the support frame 50 and below the bag 70.

[0023] [Packaging 10] The packaging body 10 is a box-shaped functional element that houses the bag 70 inside and allows the bag 70 to be transported to various locations, and constitutes the outermost part of the packaging equipment 1A. As shown in Figure 1, the packaging body 10 has the form of a rectangular parallelepiped with six sides, more specifically, a rectangular parallelepiped with side walls 20 surrounding the front, back, left, and right sides, a top wall 30 surrounding the top, and a bottom wall 40 surrounding the bottom. The storage section W in which the bag 70 and the like are housed is formed within the space defined by the side walls 20, the top wall 30, and the bottom wall 40.

[0024] The side walls 20, top wall 30, and bottom wall 40 are formed from a material that allows the packaging body 10 to possess a predetermined mechanical strength (tensile strength) and rigidity. In this embodiment, each is formed from a sheet of corrugated cardboard. The side walls 20, top wall 30, and bottom wall 40, made of corrugated cardboard, are connected via folded edges, and a corrugated cardboard box is formed by assembling them. In addition to corrugated cardboard, thin steel sheets, stainless steel sheets, aluminum sheets, or plastic sheets may also be used. Furthermore, if the side walls 20, top wall 30, and bottom wall 40 are configured as separate elements, different materials may be used for each.

[0025] The side walls 20 that make up the sides of the packaging body 10 are constructed by folding a single sheet of corrugated cardboard into a rectangular tube shape, thereby forming flat rectangular first side 21a, second side 21b, third side 21c, and fourth side 21d. The first side 21a and the second side 21b are located opposite each other, and the third side 21c and the fourth side 21d are located opposite each other. The side walls 20 are not limited to this form and may be in various other cylindrical shapes such as cylindrical, hexagonal, or octagonal shapes.

[0026] The side wall portion 20 is provided with a handle hole 22 that opens at a predetermined position above the first side surface 21a. The second and third side surfaces 21b and 21c are also provided with handle holes 23 and 25 that open at predetermined positions above them. Each of the handle holes 22, 23, and 25 functions as a handle when the package 10 is carried by inserting a finger into it. Each of the handle holes 22, 23, and 25 is formed as a roughly rectangular hole large enough to allow at least one human finger to be inserted so that it can function as a handle. The form (position, number, shape, and size) of each of the handle holes 22, 23, and 25 can be changed in various ways.

[0027] The top wall portion 30 that constitutes the top surface of the packaging body 10 is configured to be openable and closable so that the bag body 70 can be easily inserted and removed. In this embodiment, the flat first top surface 31a, second top surface 31b, third top surface 31c, and fourth top surface 31d are connected to the first side surface 21a, second side surface 21b, third side surface 21c, and fourth side surface 21d, respectively, in a foldable manner. Folds are formed at the connection points between the first top surface 31a and the first side surface 21a, the second top surface 31b and the second side surface 21b, the third top surface 31c and the third side surface 21c, and the fourth top surface 31d and the fourth side surface 21d, thereby enabling repeated opening and closing. If the side wall portion 20 and the top wall portion 30 are separate parts, they may be connected to each other via connecting elements such as hinges.

[0028] The first upper surface 31a and the second upper surface 31b are positioned opposite each other and open and close in the manner of double doors, with the connecting portion with the first side surface 21a and the second side surface 21b as the pivot axis. Similarly, the third upper surface 31c and the fourth upper surface 31d are positioned opposite each other and open and close in the manner of double doors, with the connecting portion with the third side surface 21c and the fourth side surface 21d as the pivot axis.

[0029] The upper wall portion 30 has a gap for the dispensing tube 72, which is provided on the bag body 70 described later, to protrude outwards from the upper wall portion 30. In this embodiment, an opening 32 is provided on the fourth upper surface 31d, and notches 33 and 34 are provided on the first upper surface 31a and the second upper surface 31b. The notches 33 and 34 are formed in a position that communicates with the opening 32 when the upper wall portion 30 (first upper surface 31a, second upper surface 31b, third upper surface 31c and fourth upper surface 31d) is in a closed state, and the above-mentioned gap is formed. The upper wall portion 30 also has a finger opening to facilitate the transport of the packaging body 10 (packaging equipment 1A). In this embodiment, a finger opening 35 is opened on the third upper surface 31c. This finger opening 35 is provided so as to be located above the handle hole 25 when the packaging body 10 is assembled into a predetermined shape. When transporting the package 10 (packaging equipment 1A) manually, the thumb is inserted into the finger opening 35, and the other fingers are inserted into the gripping holes 25. This allows the package 10 (packaging equipment 1A) to be securely gripped using all five fingers, making it possible to transport the package 10 (packaging equipment 1A) with one hand. Multiple finger openings may be provided. For example, finger openings may be provided above the gripping holes 22 and 23 when the package 10 is assembled into a predetermined shape.

[0030] In this embodiment, the bottom wall portion 40 that constitutes the lower surface of the packaging body 10 is constructed by foldably connecting a flat plate-shaped first bottom surface 41a, second bottom surface 41b, third bottom surface 41c, and fourth bottom surface 41d to the first side surface 21a, second side surface 21b, third side surface 21c, and fourth side surface 21d, respectively. Folds are formed at the connection points between the first bottom surface 41a and the first side surface 21a, the second bottom surface 41b and the second side surface 21b, the third bottom surface 41c and the third side surface 21c, and the fourth bottom surface 41d and the fourth side surface 21d, thereby facilitating the closing of the bottom surface. If the side wall portion 20 and the bottom wall portion 40 are separate components, they may be connected to each other via connecting elements such as hinges.

[0031] The first lower surface 41a and the second lower surface 41b are positioned opposite each other and open and close in the manner of double doors, with the connecting portion with the first side surface 21a and the second side surface 21b as the pivot axis. Similarly, the third lower surface 41c and the fourth lower surface 41d are positioned opposite each other and open and close in the manner of double doors, with the connecting portion with the third side surface 21c and the fourth side surface 21d as the pivot axis.

[0032] The first lower surface 41a and the second lower surface 41b have overlapping projections 413a and 413b projecting downwards via folding lines 411a and 411b, respectively. The positions of the folding lines 411a and 411b are the same as the positions of the lower edges of the third lower surface 41c and the fourth lower surface 41d, so that when the first lower surface 41a and the second lower surface 41b are folded inwards, the positions of the folding lines 411a and 411b are approximately the same.

[0033] At the center of the fold line 411a and the center of the fold line 411b, there are circular, through-openings forming the rocking support member housing holes 415a and 415b, respectively. The rocking support member housing holes 415a and 415b are formed at positions that are bisected by the fold lines 411a and 411b, respectively. The rocking support member housing holes 415a and 415b are the same size and are formed with a diameter slightly smaller than or approximately the same as the diameter of the rocking support member 120 described below.

[0034] [Support frame 50] The support frame 50 is a functional element that interposes between the packaging body 10 and the bag body 70, supporting the bag body 70 containing the fluid substance in a stable position within the storage compartment W of the packaging body 10, while shaping it into a predetermined form and keeping it at a predetermined distance from the side wall portion 20 of the packaging body 10. In this embodiment, the support frame 50 is constructed by forming corrugated cardboard into a polygonal cylindrical body. The bag body 70 is housed within the storage compartment W1 of the support frame 50. At 180° opposite positions on the upper part of the support frame 50, there are two hand-holding holes 51 consisting of a pair of substantially rectangular parallelepiped-shaped through holes. The basic form of the support frame 50 is not limited to the cylindrical body described above; for example, it may be a pentagonal cylindrical body or a circular cylindrical body. This support frame 50 also functions as a mixing chamber for mixing the fluid substance inside the bag body 70.

[0035] [Bag body 70] The bag body 70 is a functional element that allows contents (fluid substances) to be easily dispensed and stored in an airtight state for a long period of time. It mainly consists of a bag body 71 that contains the contents (fluid substances) inside, a dispensing tube 72 that connects the inner space and the outer space of the bag body 71, and a lid 73 that closes the dispensing tube 72.

[0036] The bag body 71 is a flexible bag-shaped component, which in this embodiment is made of a synthetic resin film and can be inflated by sealing a fluid substance inside. The bag body 71 has predetermined mechanical strength (especially tensile strength), heat resistance, and stretchability (elasticity), and is preferably made of a transparent material, such as polypropylene, which allows the sealed contents to be seen from the outside. However, it is not limited to this material, and any material may be used as long as it has the above properties.

[0037] The dispensing tube 72 and lid 73 are functional elements that enable the pouring of a fluid substance such as paint into the bag body 71 or the pouring of a fluid substance such as paint placed inside the bag body 71 to the outside, and that enable the bag body 71 to be kept airtight for a long period of time. The dispensing tube 72 and lid 73 are made of, for example, a resin material, and are detachably connected to each other by screwing together, for example, a male thread formed on one and a female thread formed on the other.

[0038] [Means for stirring fluidized material 100] The fluid substance stirring means 100 is a functional element that stirs the fluid substance by generating and / or increasing motion such as oscillating and vibration caused by forces acting on the packaging equipment 1A (packaging equipment 1A comprising a bag 70 filled with fluid substance and a packaging body 10 that houses the bag 70) during transport, etc., and is configured to include a bag mounting member 110 and an oscillating support member 120. The bag mounting member 110 is a functional element that allows the bag 70 to be oscillatingly mounted, and is formed, for example, as a circular plate with dimensions that allow it to be oscillatingly stored within the storage section W1 of the support frame 50. The shape of the bag mounting member 110 is not limited to a circle, and may be any other shape or structure as long as it can support and oscillate the bag 70. In this embodiment, the bag mounting member 110 is made of corrugated cardboard, but may be made of any other material such as synthetic resin. In short, any member that has sufficient strength to support and swing the bag 70 is acceptable. The swinging support member 120 is configured, for example, as a solid or hollow sphere made of synthetic resin, and is positioned in the center of the lower surface of the bag support member 110 on which the bag 70 filled with a fluid substance is placed, thereby supporting the bag support member 110 so that it can swing freely. The swinging support member 120 can be described as a swinging support member that swings the bag support member 110, which is installed on the bottom surface of the storage section W of the packaging body 10. As will be described later, the swinging support member 120 is configured to be inserted into a swinging support member storage hole 415 (more specifically, a swinging support member storage hole 415 formed from a pair of swinging support member storage holes 415a and 415b) formed in the bottom wall portion 40 of the packaging body 10, but it may also be configured to be placed in a hole (not shown) formed in the bag support member 110 instead of, or additionally. Furthermore, the swinging support member 120 is not limited to the above-described form, and may be any form that can perform the function of a swinging support member. That is, it may be a form that contacts the bag support member 110, on which the bag 70 filled with a fluid substance is placed, at two or fewer points or in a straight line, for example, a hemisphere, a cone-shaped body, or a strip-shaped body, so that the bag support member 110 can easily swing with slight vibrations, etc. In addition, the swinging support member 120 may be made of a material other than synthetic resin, such as paper.

[0039] [Assembly method for packaging equipment 1A] An example of how to assemble packaging equipment 1A is described below. Here, we will assemble the packaging body 10 starting from the bottom wall portion 40. First, the overlapping projection 413a of the first bottom surface 41a and the overlapping projection 413b of the second bottom surface 41b are folded outwards (away from the storage compartment W) at the folding lines 411a and 411b, respectively, and overlapped with the outer surface of the first bottom surface 41a and the outer surface of the second bottom surface 41b. Next, the first and second bottom surfaces 41a and 41b, from which the overlapping projections 413a and 413b have been folded, are folded inwards (towards the inside of the storage compartment W, and so on) at the connecting portions with the first and second sides 21a and 21b, respectively.

[0040] Figure 2 is a schematic perspective view showing the state of the packaging body 10 at this time, and Figure 3 is a schematic perspective view of the main part showing only the first and second lower surfaces 41a and 41b at this time. As shown in these figures, by bending the overlapping protrusions 413a and 413b, a pair of semicircular swing support member storage holes 415a and 415b are formed, and by bending the first and second lower surfaces 41a and 41b and joining the portions of the two bend lines 411a and 411b, a single circular swing support member storage hole 415 is formed. Also, as shown by the dotted line in Figure 3, guide grooves 45 are pre-formed on the inner bottom surfaces (the surfaces that become the bottom surface of the storage section W) of the first and second lower surfaces 41a and 41b, respectively, and when the two are joined together, they form a single annular recess. The guide grooves 45 are used to insert the lower end edge 53 (see Figure 1) of the support frame 50 and position the support frame 50 inside the packaging body 10. The guide grooves 45 are formed by compressing and molding the first and second lower surfaces 41a and 41b, which are made of corrugated cardboard, or by cutting notches into them. The guide grooves 45 are formed with a predetermined gap from the inner periphery surrounding the inner bottom surface of the storage section W of the packaging body 10 (the connecting part between the first to fourth side surfaces 21a to 21d and the first to fourth lower surfaces 41a to 41d).

[0041] Next, the third and fourth lower surfaces 41c and 41d shown in Figure 2 are folded inward and overlapped with the lower surfaces of the first and second lower surfaces 41a and 41b. Then, the joining edges (tip edges) of the two surfaces are connected and fixed with adhesive tape or metal fittings to complete the bottom wall section 40.

[0042] Next, the support frame 50 shown in Figure 1 is placed inside the packaging body 10, which has the bottom wall portion 40 assembled, from the upper side of the open storage portion W. At this time, the lower end edge 53 of the support frame 50 is locked into the guide groove 45, so that the outer surface of the support frame 50 and the inner surfaces of the first to fourth sides 21a to 21d do not come into contact but face each other with a predetermined gap in between.

[0043] Next, the swing support member 120 is placed inside the support frame 50 from the upper side of the open storage section W of the packaging body 10 and inserted into the swing support member storage hole 415. This positions the swing support member 120 at the center of the upper surface of the bottom wall portion 40. Furthermore, the bag body mounting member 110 is inserted into the support frame 50 and placed on the swing support member 120. As a result, the center of the lower surface of the bag body mounting member 110 is supported at one point by the swing support member 120, and it becomes swingable and rotatable in a 360° direction around this supported pivot point.

[0044] Next, as shown in Figure 4, the bag 70 is placed inside the storage section W1 of the support frame 50 from the upper side of the open storage section W of the packaging body 10. Then, as shown in Figure 5, the first and second upper surfaces 31a and 31b are folded inward, and the third and fourth upper surfaces 31c and 31d are folded over above the first and second upper surfaces 31a and 31b. At this time, the dispensing tube 72 of the bag 70 passes through the gap formed by the notches 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. The joining edges (tip edges) of the third and fourth upper surfaces 31c and 31d are then connected and fixed with adhesive tape or metal fittings to complete the upper wall section 30. Finally, the lid 73 is screwed onto the upper end opening of the dispensing tube 72 to close it. This completes the assembly of the packaging equipment 1A.

[0045] Figure 6 is a schematic longitudinal cross-sectional view of the assembled packaging equipment 1A (the cross-sectional location differs in each part for illustrative purposes). Figure 7 is an enlarged cross-sectional view of the main part, showing the vicinity of the swinging support member 120 in Figure 6. As shown in Figure 6, the packaging equipment 1A is constructed by installing a fluid substance stirring means 100 between the bottom surface of the storage section W of the packaging body 10 (the upper surface of the bottom wall section 40) and the bag body 70. At this time, the bottom surface of the bag body 70 is placed on the bag body mounting member 110 of the fluid substance stirring means 100. Also, since the lower end edge 53 of the support frame 50 is locked into the guide groove 45, the support frame 50 and the bag body 70 stored in the storage section W1 of the support frame 50 are separated from the side wall section 20 of the packaging body 10 by a predetermined distance. As shown in Figure 7, the swing support member 120 is partially housed and positioned within the swing support member housing hole 415, with the bag body mounting member 110 placed on top of it. The swing support member housing hole 415 has a first lower surface 41a (second lower surface 41b) and an overlapping projection 413a (overlapping projection 413b) that overlap, which increases the depth of the hole and allows the swing support member 120 to be held more securely within the swing support member housing hole 415.

[0046] The above assembly procedure is just one example, and it goes without saying that other different assembly procedures can also be used (the same applies to the embodiments described below).

[0047] [Instructions for using packaging equipment 1A] Next, an example of how to use packaging equipment 1A will be explained. First, the lid 73 is removed from the dispensing cylinder 72, and the fluid substance (fluid material) is filled through the opening at its upper end. Then, the lid 73 is replaced to seal the bag 70 (filling process). In this example, paint was used as the fluid substance to be filled.

[0048] Then, as shown in Figure 21, for example, the packaging equipment 1A is placed on a transport means TK such as a truck from the warehouse E1 (placement process) and transported to the site E2 where the filled fluid material will be used (transportation and mixing process). When the packaging equipment 1A is transported on the transport means TK, vibrations during transport (including acceleration and deceleration, the same applies below) transmitted from the transport means TK to the packaging equipment 1A cause the bag body placement member 110 to swing randomly and widely around the point where it is supported by the swinging support member 120, as shown by arrow A in Figure 8. As a result, the bag body 70 placed on the bag body placement member 110 also swings randomly and widely. Furthermore, the bag body placement member 110 may also swing in the rotational direction, twisting the bag body 70 while it is placed on it, around the swinging support member 120, which further effectively causes the bag body 70 to swing in the vertical and rotational directions.

[0049] This causes the fluid material inside the bag 70 to be vigorously agitated and stirred. As a result, fluid materials that have the property of separating into an oil layer and a water layer when stationary, such as paint, are stirred and thoroughly mixed.

[0050] Furthermore, in this packaging equipment 1A, the support frame 50 is separated from the side wall 20 of the packaging body 10 by a predetermined distance. Therefore, vibrations transmitted from the conveying means TK to the packaging equipment 1A during transport cause the bag 70 and the fluid material inside it to shake horizontally, as shown by arrow B in Figure 8. This also causes the fluid material to shake and be agitated, and the oil and water that make up the fluid material are thoroughly mixed. This horizontal shaking is amplified by the swinging of the bag support member 110. In other words, the synergistic effect of the two causes the fluid material to shake and be agitated even more.

[0051] Once you arrive at site E2 and unload packaging equipment 1A, there is no need to stir the fluid material again, and it can be used as is.

[0052] [Effects of Packaging Material 1A] In other words, when the packaging equipment 1A is being transported by the transport means TK, the fluid substance is stirred and mixed through the fluid substance stirring means 100. More specifically, during transport, motions such as swaying and vibration caused by inertial forces acting on the packaging equipment 1A (packaging equipment 1A comprising a bag 70 filled with fluid substance and a packaging body 10 that houses the bag 70) and forces input through the platform on which the packaging equipment 1A is placed are generated and / or amplified through the fluid substance stirring means 100, causing the fluid substance to be automatically stirred and mixed (stirring and mixing of the fluid substance is promoted). In particular, the fluid substance stirring means 100 equipped with a spherical swaying support member 120 functions to sway while changing direction in any direction in the horizontal plane, thereby suitably enabling automatic stirring and mixing of the fluid substance. As a result, the work of stirring the fluid substance again on site is eliminated, and equipment for stirring is also eliminated. From these reasons, carbon dioxide emissions can be suppressed, and stirring work can be simplified. Furthermore, because it can utilize materials such as cardboard, which are easily and relatively inexpensively recyclable, it is possible to keep carbon dioxide emissions associated with manufacturing low and reduce manufacturing costs.

[0053] ≪Second Embodiment≫ A packaging material 1B, which is one of the preferred embodiments of the present invention, will be described as a second embodiment with reference to Figures 9 to 12.

[0054] [Composition of Packaging Equipment 1B] In the packaging equipment 1B shown in Figures 9 to 12, the same or equivalent parts as those in the packaging equipment 1A shown in the embodiments of Figures 1 to 8 are denoted by the same reference numerals. Except for matters described below, the same parts are as those in the embodiments shown in Figures 1 to 8.

[0055] The only differences between the packaging equipment 1B shown in Figures 9 to 12 and the packaging equipment 1A shown in Figures 1 to 8 are the structure of the bottom wall portion 40 of the packaging body 10 and the structure of the fluid material stirring means 100. These structures will be described below in detail.

[0056] [Packaging 10] The packaging body 10 in the packaging equipment 1B also has the shape of a rectangular parallelepiped, comprising side walls 20 that surround the front, back, left, and right sides, a top wall 30 that surrounds the top, and a bottom wall 40 that surrounds the bottom, with a storage section W formed inside which a bag 70 or the like is housed.

[0057] The side wall portion 20 and the top wall portion 30 have the same configuration as the packaging material 1A according to the first embodiment described above. In this embodiment, the bottom wall portion 40 is constructed by foldably connecting the flat first bottom surface 41a, second bottom surface 41b, third bottom surface 41c, and fourth bottom surface 41d to the first side surface 21a, second side surface 21b, third side surface 21c, and fourth side surface 21d, respectively. Folds are formed at the connection points between the first bottom surface 41a and the first side surface 21a, the connection points between the second bottom surface 41b and the second side surface 21b, the connection points between the third bottom surface 41c and the third side surface 21c, and the connection points between the fourth bottom surface 41d and the fourth side surface 21d, thereby facilitating the closing of the bottom surface.

[0058] The bottom wall portion 40 of this packaging material 1A does not have the overlapping projections 413a and 413b that were provided in the packaging material 1A according to the first embodiment. That is, the positions of the lower edges of the first bottom surface 41a and the second bottom surface 41b are the same as the positions of the lower edges of the third bottom surface 41c and the fourth bottom surface 41d, so that when the first bottom surface 41a and the second bottom surface 41b are folded inward, the positions of their lower edges are approximately the same.

[0059] At the center of the lower edge of the first lower surface 41a and the center of the lower edge of the second lower surface 41b, there are semicircular recesses, which are recesses for housing the swing support member, 417a and 417b, respectively. The swing support member housing recesses 417a and 417b are the same size and are formed with a diameter slightly smaller than the radius of the swing support member 120, or approximately the same diameter.

[0060] [Means for stirring fluidized material 100] The fluid substance stirring means 100 used in the packaging equipment 1B according to the second embodiment is configured to include, in addition to the same bag mounting member 110 and swinging support member (swinging mounting member) 120 as used in the packaging equipment 1A according to the first embodiment, a plurality (4) of vibration assisting members 130.

[0061] The vibration assist member 130 is a flat, rectangular elastic body, and in this embodiment, urethane rubber having high rebound and high elasticity properties is used. The vibration assist members 130 are installed at equal intervals (90 degrees each) on the circumference of the upper surface of the bottom wall portion 40, centered on the position where the swing support member 120 is installed. These vibration assist members 130 may be attached when assembling the packaging equipment 1B, or they may be pre-attached to the first lower surface 41 and the second lower surface 41b that constitute the upper surface of the bottom wall portion 40, or they may be pre-attached to the lower surface of the bag body mounting member 110.

[0062] The vibration assisting member 130 may be a rubber-elastic member made of a material other than urethane rubber, or other elastic bodies such as coil springs, leaf springs, or hollow rubber may be used instead of rubber-elastic members.

[0063] [Assembly method for packaging equipment 1B] An example of how to assemble packaging material 1B is described below. First, the first and second lower surfaces 41a and 41b are folded inward at the points where they connect to the first and second side surfaces 21a and 21b, respectively. Figure 10 is a schematic perspective view showing the state of the packaging 10 at this point. As shown in this figure, by folding the first and second lower surfaces 41a and 41b and joining their leading edges, the pair of semicircular oscillating support member storage recesses 417a and 417b form a single circular oscillating support member storage hole 417. Although not shown in Figure 10, guide grooves 45 (see Figure 11) are pre-formed on the inner bottom surfaces of the first lower surface 41a and the second lower surface 41b, which are folded inward, and when the two are joined together, they form a single annular recess, similar to the dotted lines shown in Figure 3. This guide groove 45 is also formed with a predetermined gap from the inner periphery surrounding the inner bottom surface of the storage section W of the packaging body 10 (the connecting portion between the first to fourth side surfaces 21a to 21d and the first to fourth bottom surfaces 41a to 41d).

[0064] Next, the third and fourth lower surfaces 41c and 41d shown in Figure 10 are folded inward and overlapped with the lower surfaces of the first and second lower surfaces 41a and 41b. Then, the joining edges (tip edges) of the two surfaces are connected and fixed with adhesive tape or metal fittings to complete the bottom wall section 40.

[0065] Next, the four vibration assist members 130 are attached to the first lower surface 41 and the second lower surface 41b, which form the inner bottom surface of the packaging body 10, for example, using double-sided tape. The attachment positions are inside the guide groove 45 and at equal intervals of 90° on the circumference centered on the swing support member housing hole 417.

[0066] Then, as in the first embodiment described above, the support frame 50 is placed inside the open storage section W of the packaging body 10 from above, and then the swing support member 120 is placed inside the support frame 50 and inserted into the swing support member storage hole 417. Next, the bag body mounting member 110 is inserted inside the support frame 50 and placed on the swing support member 120. As a result, the bag body mounting member 110 can swing and rotate freely in a 360° direction by the swing support member 120.

[0067] Next, the bag body 70 is placed into the storage section W1 of the support frame body 50 from above the open storage section W of the packaging body 10. Then, the first and second upper surfaces 31a and 31b are folded inward, and the third and fourth upper surfaces 31c and 31d are folded over above the first and second upper surfaces 31a and 31b. At this time, the dispensing tube 72 of the bag body 70 passes through the gap formed by the notches 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. The joint edges of the third and fourth upper surfaces 31c and 31d are then connected and fixed with adhesive tape or metal fittings to complete the upper wall section 30. Finally, the lid 73 is screwed onto the upper end opening of the dispensing tube 72 to close it. This completes the assembly of the packaging equipment 1B.

[0068] Figure 11 is a schematic longitudinal cross-sectional view of the assembled packaging equipment 1B (the cross-sectional location differs in each part for illustrative purposes). As shown in the figure, the packaging equipment 1B is configured such that a fluid substance stirring means 100 is installed between the bottom surface of the storage section W of the packaging body 10 (the upper surface of the bottom wall portion 40) and the bag body 70, and the bottom surface of the bag body 70 is placed on the bag body mounting member 110 of the fluid substance stirring means 100.

[0069] Furthermore, since the lower end edge 53 of the support frame 50 is locked into the guide groove 45, the support frame 50 and the bag 70 stored in the storage section W1 of the support frame 50 are separated by a predetermined distance from the inner surface of the side wall 20 of the packaging body 10. Also, as shown in Figure 11, a portion of the swing support member 120 is stored in the swing support member storage hole 417 and positioned, with the bag body mounting member 110 placed on top of it. In addition, the upper surface of each vibration assist member 130 is separated by a predetermined distance from the lower surface of the bag body mounting member 110.

[0070] [Instructions for using packaging equipment 1B] Next, an example of how to use packaging equipment 1B will be explained. First, remove the lid 73 from the dispensing cylinder 72, fill it with a fluid substance (paint in this example) through the opening at its top, and then replace the lid 73 to seal the bag 70.

[0071] Then, as shown in Figure 21, for example, the packaging equipment 1B is loaded onto a transport means TK such as a truck from the warehouse E1 and transported to the site E2 where the filled fluid material will be used. When the packaging equipment 1B is transported on the transport means TK, vibrations during transport (including acceleration and deceleration) transmitted from the transport means TK to the packaging equipment 1B cause the bag body mounting member 110 to swing randomly and widely around the point where it is supported by the swinging support member 120, as shown by arrow A in Figure 12. As a result, the bag body 70 placed on the bag body mounting member 110 also swings randomly and widely. In this packaging equipment 1B, a vibration assist member 130 is also installed, so when the lower surface of the swinging swinging support member 120 comes into contact with the upper surface of the vibration assist member 130, its elastic force pushes the swinging support member 120 back in the opposite direction, creating an even more effective swinging motion.

[0072] This causes the fluid material inside the bag 70 to be vigorously agitated and stirred. As a result, fluid materials that have the property of separating into an oil layer and a water layer when stationary, such as paint, are stirred and thoroughly mixed.

[0073] Furthermore, in this packaging device 1B, as in the first embodiment described above, vibrations during transport transmitted from the transport means TK to the packaging device 1B cause the bag 70 and the fluid material inside it to shake horizontally, as shown by arrow B in Figure 12. This also causes the fluid material to shake and be agitated, and the oil and water that make up the fluid material are thoroughly mixed. This horizontal shaking is amplified by the oscillation of the bag support member 110. In other words, the synergistic effect of the two causes the fluid material to shake and be agitated even more.

[0074] Once you arrive at site E2 and unload packaging equipment 1B, there is no need to stir the fluid material again, and it can be used as is.

[0075] [Effects of Packaging Equipment 1B] As described above, in packaging equipment 1B, as with packaging equipment 1A, the fluid material is automatically agitated and mixed while being transported by the transport means TK. In particular, the fluid material agitation means 100 equipped with the vibration assist member 130 functions to generate more suitable oscillations, resulting in effective automatic agitation and mixing. This eliminates the need for manual agitation of the fluid material on-site, and also eliminates the need for agitation equipment. As a result, carbon dioxide emissions can be reduced, and the agitation process can be simplified. Furthermore, since materials such as corrugated cardboard, which can be recycled easily and relatively inexpensively, can be used, carbon dioxide emissions associated with manufacturing can be kept to a minimum, and manufacturing costs can be reduced.

[0076] ≪Third Embodiment≫ A packaging material 1C, which is one of the preferred embodiments of the present invention, will be described as a third embodiment with reference to Figures 13 to 14.

[0077] [Composition of Packaging Equipment 1C] Figure 13 is a schematic longitudinal cross-sectional view of the assembled packaging equipment 1C (the cross-sectional location differs in each part for illustrative purposes). In the packaging equipment 1C shown in Figure 13, the same or equivalent parts as those in the packaging equipment 1A and 1B shown in the embodiments of Figures 1 to 12 are denoted by the same reference numerals. Except for matters described below, the same as those in the embodiments shown in Figures 1 to 12.

[0078] The only differences between the packaging equipment 1C shown in Figure 13 and the packaging equipment 1A and 1B shown in Figures 1 to 12 are the structure of the bottom wall portion 40 of the packaging body 10 and the structure of the fluid material stirring means 100. These structures will be described below in detail.

[0079] [Packaging 10] In the packaging body 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, 413b and swing support member storage holes 415a, 415b provided in the packaging equipment 1A, and the swing support member storage recesses 417a, 417b provided in the packaging equipment 1B are not provided.

[0080] [Means for stirring fluidized material 100] The fluid substance stirring means 100 used in the packaging equipment 1C according to the third embodiment is configured to include a plurality (5) of elastic members 140 in addition to the same bag-holding member 110 used in the packaging equipment 1A and 1B according to the first and second embodiments.

[0081] The resilient members 140 are elastic bodies made of springs, and one is installed at the center of the upper surface of the bottom wall portion 40, and four are installed at equal intervals (90 degrees apart) on the circumference centered on the central position. The bag support member 110 is made swingable by the resilient members 140.

[0082] In addition, instead of a spring, the resilient member 140 may be a urethane rubber vibration assist member 130 used in the second embodiment described above, or other elastic materials such as leaf springs or hollow rubber.

[0083] [Instructions for using packaging equipment 1C] Next, an example of how to use the packaging equipment 1C will be described. First, the lid 73 is removed from the dispensing cylinder 72, and the fluid substance (paint in this example) is filled through the opening at its upper end. Then, the lid 73 is replaced to seal the bag body 70. This packaging equipment 1C is then loaded onto a transport means TK, such as a truck, from the warehouse E1, as shown in Figure 21, and transported to the site E2 where the filled fluid substance will be used. When the packaging equipment 1C is transported on the transport means TK, vibrations during transport are transmitted from the transport means TK to the packaging equipment 1C. As shown by arrow A in Figure 14, the bag body support member 110 swings randomly and significantly due to the variation in the length of each elastic member 140. As a result, the bottom surface of the bag body 70 placed on the bag body support member 110 also swings randomly and significantly.

[0084] This causes the fluid material inside the bag 70 to be vigorously agitated and stirred. As a result, fluid materials that have the property of separating into an oil layer and a water layer when stationary, such as paint, are stirred and thoroughly mixed.

[0085] Furthermore, in this packaging device 1C, as in the first and second embodiments described above, vibrations during transport transmitted from the transport means TK to the packaging device 1C cause the bag 70 and the fluid material inside it to shake horizontally, as shown by arrow B in Figure 14. This also causes the fluid material to shake and be agitated, and the oil and water that make up the fluid material are thoroughly mixed. This horizontal shaking is amplified by the oscillation of the bag support member 110. In other words, the synergistic effect of the two causes the fluid material to shake and be agitated even more.

[0086] Then, upon arriving at site E2 and unloading packaging equipment 1C, there is no need to stir the fluid substance again, and it can be used as is.

[0087] [Effects of Packaging Equipment 1C] As described above, in packaging equipment 1C, just like in packaging equipment 1A and 1B, the fluid material is automatically agitated and mixed while being transported by the transport means TK. This eliminates the need for manual agitation of the fluid material on-site, and also eliminates the need for agitation equipment. As a result, carbon dioxide emissions can be reduced and the agitation process can be simplified. Furthermore, since materials such as corrugated cardboard, which can be recycled easily and at relatively low cost, can be used, carbon dioxide emissions associated with manufacturing can be kept to a minimum, and manufacturing costs can be reduced.

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

[0089] [Composition of Packaging Equipment 1D] Figure 15 is a schematic longitudinal cross-sectional view of the assembled packaging equipment 1D (the cross-sectional location differs in each part for illustrative purposes). In the packaging equipment 1D shown in Figure 15, the same or equivalent parts as those in the packaging equipment 1A and 1B of the embodiments shown in Figures 1 to 12 are denoted by the same reference numerals. Except for matters described below, the same as those in the embodiments shown in Figures 1 to 12.

[0090] The only differences between the packaging equipment 1D shown in Figure 15 and the packaging equipment 1A and 1B shown in Figures 1 to 12 are the structure of the bottom wall portion 40 of the packaging body 10 and the structure of the fluid material stirring means 100. These structures will be described below in detail.

[0091] [Packaging 10] In the packaging body 10 of the packaging equipment 1D, similar to the bottom wall portion 40 of the packaging body 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, 413b and swing support member storage holes 415a, 415b provided in the packaging equipment 1A, and the swing support member storage recesses 417a, 417b provided in the packaging equipment 1B are not provided.

[0092] [Means for stirring fluidized material 100] The fluid substance stirring means 100 used in the packaging equipment 1D according to the fourth embodiment is configured to include, in addition to the same bag-holding member 110 used in the packaging equipment 1A and 1B according to the first and second embodiments, a swinging support member 150 attached to the lower surface of the bag-holding member 110.

[0093] The swing support member 150 is made of a molded product of synthetic resin, for example, which is convex in the downward direction. The swing support member 150 has a flat upper surface and a spherical lower surface, and the upper surface is fixed to the center of the lower surface of the bag body mounting member 110 by adhesive or the like.

[0094] [Instructions for using packaging equipment 1D] Next, an example of how to use the packaging equipment 1D will be described. The packaging equipment 1D, in which a fluid substance (paint in this example) is filled into a bag 70 and sealed, is loaded onto a transport means TK such as a truck from warehouse E1 and transported to the site E2 where the filled fluid substance will be used, as shown in Figure 21. When the packaging equipment 1D is transported on the transport means TK, the bag body support member 110, which is supported at one point by the swing support member 150, swings randomly and greatly due to vibrations during transport transmitted from the transport means TK to the packaging equipment 1D, and as a result the bottom surface of the bag body 70 placed on the bag body support member 110 also swings randomly and greatly.

[0095] This causes the fluid material inside the bag 70 to be vigorously agitated and stirred. As a result, fluid materials that have the property of separating into an oil layer and a water layer when stationary, such as paint, are stirred and thoroughly mixed.

[0096] Furthermore, in this packaging device 1D, as in the first, second, and third embodiments described above, vibrations transmitted from the conveying means to the packaging device 1D during transport cause the bag 70 and the fluid material inside it to shake horizontally. This also causes the fluid material to shake and be agitated, and the oil and water that make up the fluid material are thoroughly mixed. This horizontal shaking is amplified by the oscillation of the bag support member 110. In other words, the synergistic effect of the two causes the fluid material to shake and be agitated even more.

[0097] Then, upon arriving at site E2 and unloading packaging equipment 1D, there is no need to further agitate the fluid substance, and it can be used as is.

[0098] [Effects of Packaging Equipment 1D] As described above, in packaging equipment 1D, just like in packaging equipment 1A, 1B, and 1C, the fluid material is automatically agitated and mixed while being transported by the transport means TK. This eliminates the need for manual agitation of the fluid material on-site, and also eliminates the need for agitation equipment. As a result, carbon dioxide emissions can be reduced and the agitation process can be simplified. Furthermore, since materials such as corrugated cardboard, which can be recycled easily and relatively inexpensively, can be used, carbon dioxide emissions associated with manufacturing can be kept to a minimum, and manufacturing costs can be reduced.

[0099] ≪Fifth Embodiment≫ A packaging material 1E, which is one of the preferred embodiments of the present invention, will be described as a fifth embodiment with reference to Figures 16 to 20.

[0100] [Composition of Packaging Equipment 1E] In the packaging equipment 1E shown in Figures 16 to 20, the same or equivalent parts as those in the packaging equipment 1A to 1D according to the embodiments shown in Figures 1 to 15 are denoted by the same reference numerals. Except for matters described below, the same parts are as those in the embodiments shown in Figures 1 to 15.

[0101] The only difference between the packaging equipment 1E shown in Figures 16 to 20 and the packaging equipment 1A to 1D shown in Figures 1 to 15 is that the bottom wall portion 40 of the packaging body 10 is provided with a means for stirring fluid substances 100. The following will mainly describe this structure.

[0102] [Packaging body 10 and fluid material stirring means 100] The packaged body 10 in this packaging material 1E also has side wall portions 20 and top wall portions 30 similar to those shown in the packaging materials 1A to 1D. In this embodiment, the bottom wall portion 40 is constructed by flexibly connecting flat first bottom surface 41a, second bottom surface 41b, third bottom surface 41c, and fourth bottom surface 41d to the first side surface 21a, second side surface 21b, third side surface 21c, and fourth side surface 21d, respectively.

[0103] The first lower surface 41a and the second lower surface 41b, which constitute the bottom wall portion 40 of this packaging material 1E, have a fluid material stirring projection 419a and 419b projecting downwards via fold lines 418a and 418b, respectively. The positions of the fold lines 418a and 418b are the same as the positions of the lower edges of the third lower surface 41c and the fourth lower surface 41d, so that when the first lower surface 41a and the second lower surface 41b are folded inward, the positions of the fold lines 418a and 418b are approximately the same. The fluid material stirring projections 419a and 419b are rectangular strips, and their horizontal length is shorter than the length of the lower edges of the first lower surface 41a and the second lower surface 41b, and they are formed in the center of these lower edges. These fluid material stirring protrusions 419a and 419b together constitute the fluid material stirring means 100.

[0104] The fluid substance stirring protrusions 419a and 419b constituting the fluid substance stirring means 100 are not limited to the above configuration, and may be any configuration as long as they protrude from the bottom wall portion 40. For example, a plurality of rectangular strip-shaped fluid substance stirring protrusions may be arranged spaced apart and parallel to each other, or they may be arranged so as to intersect each other, or one or more point-shaped fluid substance stirring protrusions may be arranged so as to protrude from the bottom wall portion 40.

[0105] [Assembly method for packaging equipment 1E] An example of how to assemble packaging equipment 1E is described below. First, the fluid material stirring protrusions 419a and 419b are folded inward at the fold lines 418a and 418b, respectively, and the first lower surface 41a and the second lower surface 41b are folded inward at the connecting parts with the first and second side surfaces 21a and 21b, respectively. Figure 17 is a schematic perspective view showing the state of the packaging body 10 at this time, and Figure 18 is a schematic perspective view of the main parts showing only the first and second lower 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 fluid material stirring protrusions 419a and 419b are joined together to become a single fluid material stirring means 100, which protrudes upright from the inner bottom surfaces of the first and second lower surfaces 41a and 41b toward the inside of the storage section W.

[0106] In this embodiment as well, as shown by the dotted line in Figure 18, guide grooves 45 are pre-formed on the inner bottom surfaces of the first and second lower surfaces 41a and 41b, respectively, which are semicircular in shape and form a single annular recess when the two are joined together.

[0107] Next, the third and fourth lower surfaces 41c and 41d shown in Figure 17 are folded inward and superimposed on the first and second lower surfaces 41a and 41b. Then, the joining edges (tip edges) of the two surfaces are connected and fixed with adhesive tape or metal fittings to complete the bottom wall portion 40.

[0108] Then, the support frame 50 is placed in the open storage section W of the packaging body 10 from above, the bag 70 is placed inside the storage section W1 of the support frame 50, the first and second upper surfaces 31a and 31b are folded inward, and then the third and fourth upper surfaces 31c and 31d are folded inward and secured. Finally, the lid 73 is screwed onto the upper opening of the dispensing cylinder 72 to close it. This completes the assembly of the packaging equipment 1E.

[0109] Figure 19 is a schematic longitudinal cross-sectional view of the assembled packaging equipment 1E (the cross-sectional location differs in each part for illustrative purposes). As shown in the figure, the packaging equipment 1E has a fluid substance stirring means 100 installed between the bottom surface of the storage section W of the packaging body 10 (the upper surface of the bottom wall section 40) and the bag body 70. The fluid substance stirring means 100 is provided protruding from the bottom surface of the storage section W of the packaging body 10 and pushes a part of the lower surface (the central part) of the bag body 70 into the interior of the bag body 70. An internal intrusion portion 75 is formed on the lower surface of the bag body 70 that has been pushed inward.

[0110] [Instructions for using packaging equipment 1E] Next, an example of how to use packaging equipment 1E will be explained. First, remove the lid 73 from the dispensing cylinder 72, fill it with a fluid substance (paint in this example) through the opening at its top, and then replace the lid 73 to seal the bag 70.

[0111] Then, as shown in Figure 21, for example, the packaging material 1E is loaded onto a transport means TK such as a truck from the warehouse E1 and transported to the site E2 where the filled fluid material will be used. When the packaging material 1E is transported on the transport means TK, vibrations during transport transmitted from the transport means TK to the packaging material 1E create a flow of fluid material inside the bag 70. However, this flow is disturbed when it passes over the internal intrusion portion 75 formed on the lower surface of the bag 70, as shown by arrow C in Figure 20.

[0112] By disturbing the flow of the fluid material inside the bag 70 in this way, the stirring effect of the fluid material is also increased. As a result, fluid materials that have the property of separating into an oil layer and a water layer when stationary, such as paint, are stirred and mixed more effectively.

[0113] Furthermore, in this packaging device 1E, as with the first to fourth embodiments described above, vibrations during transport transmitted from the transport means TK to the packaging device 1E cause the bag 70 and the fluid material inside it to shake horizontally, as shown by arrow B in Figure 20. This also causes the fluid material to shake and be agitated, and the oil and water that make up the fluid material are thoroughly mixed. This horizontal shaking is amplified by the turbulence of the flow of the fluid material caused by the internal intrusion portion 75. In other words, the synergistic effect of the two causes the fluid material to shake and be agitated even more.

[0114] Then, upon arriving at site E2 and unloading packaging equipment 1E, there is no need to stir the fluid substance again, and it can be used as is.

[0115] [Effects of Packaging Material 1E] As described above, in packaging equipment 1E, just like in packaging equipment 1A to 1D, the fluid material is automatically agitated and mixed while being transported by the transport means TK. This eliminates the need for manual agitation of the fluid material on-site, and also eliminates the need for agitation equipment. As a result, carbon dioxide emissions can be reduced and the agitation process can be simplified. Furthermore, since materials such as corrugated cardboard, which can be recycled easily and at relatively low cost, can be used, carbon dioxide emissions associated with manufacturing can be kept to a minimum, and manufacturing costs can 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 described above, the fluid substance stirring means 100 is disposed within the storage section W, which is the internal space of the packaging body 10, more specifically, between the bottom surface of the storage section W and the bag body 70. As a variation 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 on the outside of the packaging body 10. This external fluid substance stirring means 200 may be a substitute for the fluid substance stirring means 100 disposed within the storage section W, or it may be an addition to the fluid substance stirring means 100.

[0117] Figure 22 shows a packaging device 1A' in which the packaging device 1A according to the first embodiment is further equipped with an external fluid substance stirring means 200A, more specifically, a packaging device 1A' in which the external fluid substance stirring means 200A is disposed on the outside of the packaging body 10 that constitutes the packaging device 1A. That is, the packaging device 1A' is equipped with a fluid substance stirring means 100 disposed on the inside of the packaging body 10, and an external fluid substance stirring means 200A disposed on the outside of the packaging body 10. Note that the fluid substance stirring means 100 may not be disposed on the inside of the packaging body 10, and the external fluid substance stirring means 200A may be disposed only on the outside of the packaging body 10.

[0118] The external fluid material stirring means 200A comprises at least a packaging body mounting member 210 on which the packaging body 10 is placed on its upper surface, and a swinging support member 220 provided on the lower surface of the packaging body mounting member 210.

[0119] The packaging support member 210 is a functional element for pivotably supporting the packaging body 10 that contains the bag 70 filled with a fluid substance. That is, although the packaging support member 210 differs in whether the bag 70 filled with the fluid substance is placed directly on it or on it via the packaging body 10, it is an element common to the bag support member 110 according to the first to fourth embodiments in that it has the main function of pivotably supporting a heavy object. The packaging support member 210 is configured as a flat plate-shaped member formed so that its shape in plan view is the same as that of the packaging body 10, or wider than that of the packaging body 10.

[0120] The packaging support member 210 may be equipped with a structure to prevent the packaging 10 from falling off the packaging support member 210 even if the packaging 10 shakes violently, for example, a retaining wall 211 as such a structure. This retaining wall 211 is provided projecting along the outer edge of the packaging support member 210 such that, for example, the plan view shape formed by its inner surface is complementary to the plan view shape of the lower part of the packaging 10, and a accommodating space H is formed inside this retaining wall 211 where the lower part of the packaging 10 is placed. The retaining wall 211 receives a reaction force from the force (inertial force, etc.) acting on the packaging 10 when the packaging 10 containing the bag 70 filled with fluid material shakes violently. For this reason, it is desirable that the dimensions (height, thickness, and contact area with the packaging 10, etc.) of the retaining wall 211 be set so as to be able to withstand this reaction force. For example, the dimensions may be set considering the vertical oscillation range of the packaging body 10, the weight of the packaging body 10 containing the bag 70 filled with the fluid substance, and the position of the center of gravity. In the packaging equipment 1A' shown in Figure 22, a friction member M with a large static friction coefficient is provided as an optional element between the packaging equipment 1A and the external fluid substance stirring means 200A, more specifically between the lower surface of the packaging body 10 and the upper surface of the packaging body support member 210.

[0121] The structure for preventing the packaging body 10 from falling off the packaging body support member 210 is not limited to the form of the retaining wall 211, but can be any structure as long as the relative movement of the packaging body 10 and the packaging body support member 210 in the horizontal plane is restricted and the two are detachable. For example, a concave portion and a convex portion having complementary shapes may be arranged in pairs on at least a part of two opposing surfaces, i.e., at least a part of the outer surface of the bottom wall portion 40 of the packaging body 10 and at least a part of the upper surface of the packaging body support member 210.

[0122] It is desirable that the packaging support member 210 be made of a material and have a shape such that it does not deform even when a packaging body 10 containing a bag 70 filled with a fluid substance is placed on it. Furthermore, in the case of a packaging support member 210 equipped with a retaining wall 211, it is desirable that the material and shape be made of a material and have a shape such that it does not deform or break even when the packaging body 10 containing the bag 70 filled with a fluid substance is violently shaken, due to the force input from the packaging body 10 (for example, the reaction force of the inertial force acting on the packaging body 10). For example, it is useful to form the packaging support member 210 from a metal or polymer material (synthetic resin) with high mechanical properties such as tensile strength and Young's modulus, and to increase rigidity by appropriately providing ribs, etc. In addition, when forming the packaging support member 210 from paper (corrugated cardboard, etc.) which has relatively inferior mechanical properties, it is useful to use a honeycomb structure.

[0123] Alternatively, the bottom wall portion 40 of the packaging body 10 and the packaging body support member 210 may be configured to be integrally molded. For example, the bottom wall portion 40 of the packaging body 10 may also serve as the packaging body support member 210. In this integrally molded configuration, a structure such as a retaining wall 211 to prevent the packaging body 10 from falling off the packaging body support member 210 becomes unnecessary.

[0124] A rocking support member 220 is provided on the lower surface of the packaging support member 210. This rocking support member 220 is an element that shares its main function with the rocking support member 120 according to the first and second embodiments, and the rocking support member 150 according to the fourth embodiment. That is, the rocking support member 220 is a functional element for rocking the packaging 10 placed on the packaging support member 210 by utilizing forces such as inertial force acting on the packaging 10 and the bag 70 filled with a fluid substance contained inside it. The rocking support member 220 is formed, for example, as a hemisphere projecting downward from the center of the lower surface of the packaging support member 210. More specifically, it is configured as a molded product of synthetic resin with a similar form to the rocking support member 150, that is, with a flat upper surface and a spherical lower surface, and the upper surface is fixed to the center of the lower surface of the packaging support member 210 by adhesive or the like. As a result, the packaging support member 210 is supported by the swinging support member 220 and a portion of its own lower surface contacting the loading platform of the transport means TK. The shape of the swinging support member 220 can be any shape as long as it can swingably support the packaging support member 210 on which the packaging 10 containing the bag 70 filled with the fluid substance is placed. That is, the swinging support member 220 provided on the lower surface of the packaging support member 210 only needs to be formed so that it contacts the loading platform of the transport means TK at two or fewer points, or in a straight line. For example, it may be in the form of a weight-shaped body or a column extending on a horizontal plane (for example, a column with a semicircular or triangular vertical cross-sectional shape). In addition, it may be made of corrugated cardboard, metal, or carbon fiber instead of synthetic resin.

[0125] According to the packaging equipment 1A' equipped with the external fluid substance stirring means 200A described above, when inertial forces or forces due to vibration act on the packaging equipment 1A (packaging equipment 1A comprising a bag 70 filled with fluid substance and a packaging body 10 that houses the bag 70) during transport, etc., the packaging body mounting member 210 on which the packaging equipment 1A (packaging body 10) is placed oscillates around the oscillating support member 220, changing its orientation in any direction in the horizontal plane. The fluid substance is automatically stirred and mixed by this oscillating motion. This automatic stirring is more desirable due to the synergistic effect with the automatic stirring (automatic stirring provided by the packaging equipment 1A) brought about by the fluid substance stirring means 100A being arranged inside the packaging body 10.

[0126] Figure 23 shows an external fluid material stirring means 200B in which a mounting member 215 is added to the external fluid material stirring means 200A. The mounting member 215 is a member that is positioned between the lower surface of the packaging body mounting member 210 and the rocking support member 220 and the loading platform of the transport means TK, and is configured, for example, as a flat plate-shaped member whose plan view shape is complementary to that of the packaging body mounting member 210. With the mounting member 215 in place, the packaging body mounting member 210 and the rocking support member 220 are prevented from directly contacting the loading platform of the transport means TK, and are thus adequately protected from damage and wear.

[0127] A recess 215a with a shape complementary to the swing support member 220 may be optionally provided in the mounting member 215 in the portion facing the swing support member 220. This recess 215a is formed to have a shape complementary to the portion including the contact portion (pressure contact portion) of the swing support member 220 (the lower part of the swing support member 220), and its vertical dimension = depth is smaller than the vertical dimension = height of the swing support member 220. As a result, the entire inside of the recess 215a is configured to contact (pressure contact) with the swing support member 220. In another example, the depth and shape of the opening edge are formed so that it contacts (pressure contact) with the swing support member 220 at the opening edge. The recess 215a in this form serves the function of retaining the swing support member 220 in a predetermined position. This function restricts the horizontal movement of the packaging support member 210 to which the swinging support member 220 is fixed, and the packaging equipment 1A (packaging body 10) placed on the packaging support member 210. As a result, the packaging support member 210 on which the packaging equipment 1A (packaging equipment 1A comprising a bag body 70 filled with a fluid substance and a packaging body 10 that houses the bag body 70) is placed will remain in place without falling off the support member 215 even when violently swayed. Consequently, safe transport is achieved, and energy consumption associated with relative movement is suitably suppressed, allowing for highly efficient (energy-efficient) stirring of the fluid substance during transport.

[0128] Furthermore, a low-friction element may be provided on the surface of the recess 215a and / or the surface of the swing support member 220 to reduce the contact resistance between them. The low-friction element may be a coating agent made of fluororesin or the like. By providing a low-friction element, the swing of the packaging support member 210 to which the swing support member 220 is fixed relative to the mounting member 215 becomes more favorable (larger swing with less force).

[0129] The support member 215 moves relative to the swing support member 220 (relative rotation) and makes contact (pressure contact) with a predetermined pressure (specifically, pressure caused by the weight of the packaging body 10 that houses the bag body 70 filled with the fluid substance), and also makes contact (pressure contact) with the lower surface of the packaging body support member 210 with a predetermined impact force. For this reason, it is desirable that the support member 215 be made of a material that can withstand the above predetermined pressure (surface pressure) and impact force.

[0130] In the mounting member 215, elements that restrict relative movement, such as friction members with a high coefficient of static friction, may be optionally provided on the contact surface with the loading platform of the transport means TK. As a result, even if the packaging equipment 1A (packaging equipment 1A comprising a bag 70 filled with a fluid substance and a packaging body 10 that houses the bag 70) shakes violently, the relative movement of the external fluid substance stirring means 200B with respect to the loading platform of the transport means TK on which it is mounted is suitably restricted. By restricting this relative movement, safe transport is achieved, and energy consumption associated with relative movement is suitably suppressed, so that stirring during transport can be performed with high efficiency (in an energy-efficient manner).

[0131] Furthermore, a connecting element 225 may be provided between the packaging body mounting member 210 and the mounting member 215 to allow relative movement between the packaging body mounting member 210 and the mounting member 215 (relative oscillation around the oscillation support member 220). The connecting element 225 is made of, for example, a coil spring with 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 packaging body mounting member 210 and its lower end is joined to the upper surface of the mounting member 215. There may be one or more connecting elements 225. If there is one, it may be configured as an expandable and contractible cylindrical member that houses the oscillation support member 220 inside. By providing the connecting element 225, the elements constituting the external fluid material stirring means 200B are integrated, thereby making the handling of the external fluid material stirring means 200B easier.

[0132] The packaging equipment 1A' equipped with the external fluid material stirring means 200B provides the same effects as the packaging equipment 1A' equipped with the external fluid material stirring means 200A, in addition to the effect that the oscillating support member 220 is suitably protected from damage and wear, thereby improving durability. Furthermore, if the external fluid material stirring means 200B is equipped with a recess 215a and / or the friction member, the effects of achieving safe transport and energy-efficient automatic stirring as described above are achieved.

[0133] The external fluid material stirring means 200C shown in Figure 24 is an embodiment in which a vibration assist member 230 is additionally disposed between the packaging support member 210 and the support member 215 compared to the external fluid material stirring means 200B. The vibration assist member 230 is composed of a material having high resilience and high elasticity, such as urethane rubber, other rubber elastic material, or other elastic body such as a coil spring, leaf spring, or hollow rubber, and its upper surface is separated by a predetermined distance from the lower surface of the packaging support member 210. Figure 24 illustrates an example of a vibration assist member 230 made of urethane rubber. The arrangement of the vibration assist members 230 in plan view is not limited to a specific arrangement, but for example, a total of four vibration assist members 230 are arranged in point-symmetric positions around the rocking support member 220, one in front of and one behind the rocking support member 220, and one on each side. Connecting elements 225 may be optionally provided.

[0134] According to the packaging equipment 1A' equipped with the external fluid material stirring means 200C described above, in addition to the same effects as the packaging equipment 1A' equipped with the external fluid material stirring means 200B, the strong elastic force of the vibration assisting member 230 amplifies the oscillating motion, making automatic stirring even more suitable.

[0135] The external fluid material stirring means 200D shown in Figure 25 is a modified version of the external fluid material stirring means 200C as follows: The swing support member 220, which was attached (fixed) to the lower surface of the packaging body mounting member 210 of the external fluid material stirring means 200C, has been modified so that the swing support member 220' is attached (fixed) to the upper surface of the mounting member 215'. In addition, the recess 215a provided in the mounting member 215 of the external fluid material stirring means 200C has been modified so that a recess 210'a is provided on the lower surface of the packaging body mounting member 210'. A vibration assist member 230 may be optionally provided, and a connecting element 225 may also be optionally provided. (Figure 25 illustrates an example of the external fluid material stirring means 200D with the vibration assist member 230 and the connecting element 225 provided). Furthermore, low-friction elements may be provided on the surface of the recess 210'a and / or the surface of the swing support member 220' to reduce the contact resistance between them. The low-friction elements may be coating agents made of fluororesin or the like. By providing low-friction elements, the swinging of the packaging support member 210' with respect to the mounting member 215' to which the swing support member 220' is fixed becomes more favorable (large swinging with small force).

[0136] Furthermore, the bottom wall portion 40 of the packaging body 10 and the packaging body mounting member 210' may be integrally molded. For example, the bottom wall portion 40 of the packaging body 10 may also be configured to serve as the packaging body mounting 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 from swing support member storage recesses 417a, 417b consisting of a pair of semicircular recesses provided on the first, second lower surfaces 41a, 41b forming the inside of the bottom wall portion 40, but the recess 210'a may be formed by swing support member storage recesses 417c, 417d (not shown) consisting of a pair of semicircular recesses provided on the third, fourth lower surfaces 41c, 41d forming the outside of the bottom wall portion 40.

[0137] The external fluid material stirring means 200E shown in Figure 26 combines a mounting member 215 having a recess 215a in the external fluid material stirring means 200B and a packaging mounting member 210' having a recess 210'a in the external fluid material stirring means 200D, and a swing support member 220'' is disposed between the recess 210'a and the recess 215a. The swing support member 220'' is a member configured to be rotatable relative to the packaging mounting member 210' and the mounting member 215, and has substantially the same form as the swing support member 120 according to the first and second embodiments, that is, a solid or hollow sphere made of synthetic resin. The form of the swinging support member 220'' is not limited to a solid or hollow sphere made of synthetic resin, but can be any form that supports the packaging body 10 containing the bag body 70 filled with fluid material and is rotatable relative to the packaging body mounting member 210'' and the mounting member 215. For example, it may be made of corrugated cardboard, metal, or carbon fiber, and its shape may be, for example, a cylindrical shape with a circular vertical cross-section.

[0138] Furthermore, similar to the external fluid material stirring means 200D, a vibration assist member 230 may be optionally provided, and a connecting element 225 may also be optionally provided (Figure 26 illustrates an example of an external fluid material stirring means 200E with a vibration assist member 230 and a connecting element 225 provided). In addition, a low-friction element may be provided on the surface of the recess 210'a and / or the surface of the oscillating support member 220'' and / or the recess 215a to reduce the contact resistance between them. The low-friction element may be a coating agent made of fluororesin or the like. By providing a low-friction element, the oscillating of the packaging body mounting member 210' with respect to the mounting member 215 via the oscillating support member 220'' becomes more favorable (larger oscillating with less force). Also, similar to the external fluid material stirring means 200E, the bottom wall portion 40 of the packaging body 10 and the packaging body mounting member 210' may be integrally molded.

[0139] The external fluid material stirring means 200F shown in Figure 27 is an embodiment in which a resilient member 240 is disposed between the packaging body mounting member 210'' and the mounting member 215''. The resilient member 240 is composed of a resilient body (elastic body) made of a spring, similar to the resilient member 140 in the packaging equipment 1C according to the third embodiment, for example. One resilient member 240 is installed at the central position, and four more are installed at equal intervals (90 degrees each) on the circumference centered on the central position. Here, the resilient member 240 is not limited to any specific type as long as it is a functional element that can generate and / or increase motion such as swaying and vibration caused by inertial forces acting on the packaging equipment (bags filled with fluid material and packaging bodies that house the bags) during transport, etc., or forces input through the loading platform on which the packaging equipment is placed. Furthermore, the arrangement of the resilient members 240 can be arbitrary as long as sufficient stability is maintained so that the oscillating packaging body 10 does not fall off the external fluid material stirring means 200F. In addition, similar to the packaging body mounting member 210 in the fluid material stirring means 200C and the packaging body mounting member 210'' in the fluid material stirring means 200D, the packaging body mounting member 210'' may be integrally molded with the bottom wall portion 40 of the packaging body 10, for example, the bottom wall portion 40 of the packaging body 10 may also serve as the packaging body mounting member 210''.

[0140] The external fluid material stirring means 200G shown in Figure 28 is a fluid material stirring means in which the storage space H is expanded so that multiple packaging materials 1A' (packaging bodies 10) can be placed on the fluid material stirring means 200F. Specifically, the fluid material stirring means comprises a packaging body mounting member 210''' in which the storage space H formed in the packaging body mounting member 210''' of the fluid material stirring means 200F is expanded so that, for example, three packaging materials 1A' (packaging bodies 10) can be placed on it, and a mounting member 215''' in which the horizontal area of ​​the mounting member 215''' is expanded to match the size of the packaging body mounting member 210''', and a resilient member 240 is interposed between these packaging body mounting member 210'''' and the mounting member 215''''. Alternatively, the resilient member 240 may be changed to a swing support member 220, a swing support member 220', or a swing support member 220'', the packaging body mounting member 210'''' may be changed to a packaging body mounting member 210 or 210' with an expanded storage space H, and the mounting member 215'''' may be changed to mounting members 215 or 215' with an expanded horizontal area.

[0141] Although 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 claims, specification, and drawings. Furthermore, any shape, structure, or material not directly described in the specification and drawings is within the scope of the technical idea of ​​the present invention as long as it achieves the function and effect of the present invention. Also, the embodiments described above and shown in the figures can be combined as long as there is no contradiction in their purpose and configuration. Moreover, even a part of the descriptions above and shown in the figures can constitute an independent embodiment, and the embodiments of the present invention are not limited to a single embodiment combining the above descriptions and figures.

[0142] For example, components / members having a common function between the fluid material stirring means 100 disposed inside the packaging body 10 and the external fluid material stirring means 200 (external fluid material stirring means 200A~200G) disposed outside as a modified example, can be interchanged in terms of shape, structure, configuration, and materials, while appropriately adjusting dimensions, etc., as they are based on the same technical concept. That is, the bag body mounting member 110 and the packaging body mounting members 210, 210', and 210'', which share the main function of swinging heavy objects, can be interchanged in the above form. For example, a recess equivalent to the recess 210'a disposed in the packaging body mounting member 210' may be provided in the part of the bag body mounting member 110 facing the swing support member 120. Also, the swing support member 120 and the swing support member 220 can be interchanged in the above form because they share the same main function. Furthermore, the bottom wall portion 40 of the packaging body 10, which is configured to contact (pressure contact) with the swing support member 120, and the mounting members 215, 215', and 215'', which are configured to contact (pressure contact) with the swing support member 220, also share some functions and are therefore interchangeable in the above configuration.

[0143] Corrugated cardboard may also be used as a means for stirring fluid materials. Here, typical corrugated cardboard is mainly composed of an outer liner, an inner liner, and a corrugated core interposed between these liners, and the interposition of the core creates flutes (corrugations). Corrugated cardboard with such flutes (corrugations) has structural elasticity, and this elasticity can be used as a means for stirring fluid materials. In particular, corrugated cardboard with a relatively large core height (thickness), for example, corrugated cardboard of the A-flute standard with a core height (thickness) of 5 mm, or corrugated cardboard of the W-flute standard with laminated cores, has elasticity suitable for use as a means for stirring fluid materials. The means for stirring fluid materials made of corrugated cardboard may be disposed, for example, inside the packaging body 10 and / or outside the packaging body. Alternatively, the packaging body and the means for stirring fluid materials may be integrated by forming at least a part of the bottom of the packaging body (for example, the bottom wall portion 40 of the packaging body 10) with corrugated cardboard of the above standard. Figure 29 shows that the fluid substance stirring means 200 is constructed by arranging a W-flute corrugated cardboard 250, consisting of a front liner 251, a back liner 252, and a core 253, on the outside of the packaging body 10. The fluid substance stirring means 200 (corrugated cardboard 250) may be detachably arranged below the bottom wall portion 40 of the packaging body 10, or it may be fixed to the bottom wall portion 40 using an adhesive or the like. The fixing method is not limited to a specific form as long as it restricts the relative movement in the horizontal plane between the packaging body 10 (the bag 70 filled with the fluid substance and the packaging body 10 that houses the bag 70) and the fluid substance stirring means 200 (corrugated cardboard 250). For example, similar to the form that restricts the relative movement in the horizontal plane between the packaging body 10 and the packaging body support member 210, it may be a form in which a friction material with a large coefficient of static friction or recesses and protrusions with complementary shapes are provided on at least a part of the two opposing surfaces.
