Embodiments for Carrying out the Invention

[0012] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. <Fluid package 100> FIG. 1 is a diagram showing the overall configuration of the fluid package 100 in the present embodiment. First, the overall configuration of the fluid package 100 will be described while referring to FIG. 1.

[0013] As shown in FIG. 1, the fluid package 100 includes a bag body 1, an outflow body 2, a box body 3, and a plate body 4.

[0014] The bag body 1 is a deformable container filled with fluid inside. In the present embodiment, the fluid filled in the bag body 1 is shampoo as an example of cosmetics.

[0015] Here, the bag 1 is made of a flexible and highly liquid-tight synthetic resin. The bag 1 is made of, for example, polyolefin (polyethylene, polypropylene, etc.), polyester (polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, etc.). The bag 1 is formed as a roughly hexahedron of a size that can be stored in the box 3 without or with little gaps. In the illustrated example, the bag 1 is formed in a roughly rectangular parallelepiped shape.

[0016] Here, the bag body 1 is provided with an outlet 2 for releasing the fluid filled inside the bag body 1. To explain further, the bag body 1 has a mouth 10 formed on its top surface for releasing the fluid, and the outlet 2 is provided at this mouth 10. In other words, the mouth 10 functions as the part to which the outlet 2 is attached. The mouth 10 of the bag body 1 is a plastic molded product, made of, for example, polypropylene or polyethylene, and is formed as a cylindrical projection on the top surface of the bag body 1.

[0017] The outlet body 2, like the opening 10, is made of a plastic molded product, such as polypropylene or polyethylene, and is formed as a so-called cock type. To further explain, the outlet body 2 comprises an outlet 20 for discharging fluid, a stopper (not shown) placed inside the outlet 20 to open and close the flow path inside the outlet 20, and a cock lever 21 rotatably attached to the top of the outlet 20 to drive the stopper to open and close. In the outlet body 2, the stopper is opened and closed by the rotation of the cock lever 21, thereby controlling fluid flow. In other words, the outlet body 2 is configured to switch between allowing and not allowing fluid to flow by the rotation of the cock lever 21. Note that, unlike the illustrated example, a cap type may be used as the outlet body 2. In the cap type outlet body 2, a cap mounting part is provided integrally with or separately from the opening 10 of the bag body 1, and a cap is attached to this cap mounting part by a screw type or snap type. In this cap type, fluid flow is controlled by attaching and removing the cap.

[0018] Box 3 is a container that houses the bag 1 inside. Box 3 is rigid and made of a paper material with particularly high load-bearing strength (strength when multiple boxes 3 are stacked). The illustrated box 3 is made of so-called corrugated cardboard, but it may also be made of other paper materials such as cardboard or plastic materials. The illustrated box 3 is formed as a hexahedron with a predetermined internal space so that it can house the bag 1 and so that the plate 4, which will be described later, can be placed along a predetermined surface of the bag 1. Furthermore, box 3 is formed by assembling the blank sheet S3 shown in Figure 5, which will be described later, and attaching adhesive tape 9 to the outer surface.

[0019] The plate 4 is a flat plate member with a roughly rectangular shape in plan view, provided along the bag 1 within the internal space of the box 3. As will be described in detail later, the position of the plate 4 within the internal space of the box 3 is above the bag 1 when the box 3 is in use. This plate 4 is made of rigid paper. In the illustration, the plate 4 is made of so-called corrugated cardboard, but it may be made of other paper materials such as thick cardboard or plastic materials.

[0020] <Box 3> Next, we will explain the detailed configuration of box 3. As shown in Figure 1, the box 3 includes a protruding opening 30 for allowing the outlet 20 of the outflow body 2 provided in the bag 1 to protrude to the outside, a hand hole 40 for carrying the box 3, and an opening 300 for inserting the user's hand into the box 3 and pressing the bag 1 stored inside the box 3. The protruding opening 30 and the opening 300 will be described in detail below.

[0021] <Protrusion port 30> Figure 2 shows the area around the protruding opening 30 in the box body 3. Next, the protruding opening 30 will be described with reference to Figures 1 and 2. As shown in Figure 1, the protruding opening 30 is a roughly triangular opening formed on one side of the box body 3. As shown in Figure 2, the protruding opening 30 has an opening 30A for the outflow body 2 to protrude from the inside of the box body 3 to the outside, and a groove 30B for receiving and holding the outflow body 2 that protrudes from the opening 30A.

[0022] The opening 30A is a roughly trapezoidal opening. The opening 30A is formed on one side of the box body 3 by making an H-shaped, U-shaped, or C-shaped cut line, such as a perforation line or zipper line, and is made openable and closable by an opening / closing part 30C formed and left in place by this cut line. Note that these H-shaped, U-shaped, and C-shaped shapes are basic shapes and can be modified in various ways as appropriate depending on the overall shape adopted for the opening 30A. Furthermore, the opening / closing part 30C of this protruding opening 30 functions as a pressing part that presses the outflow body 2, which protrudes from the protruding opening 30 and is held in the groove 30B, toward the groove 30B.

[0023] The opening 30A is formed by cutting along the perforations L1 (details described later) in a horizontal, deformed H shape on one side of the hexahedron of the box body 3. In this case, the perforations L1 divide the opening / closing section 30C into two parts, which are left on one side of the box body 3. This opening / closing section 30C consists of two opening / closing plates 30L and 30R.

[0024] On the other hand, the groove 30B is a roughly circular opening. This groove 30B is formed by making a notch, such as a perforation line or zipper line, in a concave shape at the lower edge of the opening 30A so as to receive and hold the outflow 2, and cutting out the inside of the notch along this notch.

[0025] In this case, the groove 30B is formed by adding a concave perforation line L2 in the center of the lower edge of the opening 30A, in accordance with the cross-sectional shape of the mouth 10 of the bag body 1, and cutting out the inside of the perforation line L2 along this perforation line L2. Here, as described above, the opening and closing parts 30C (opening and closing plates 30L, 30R) of the protruding opening 30 function as a pressing part. A recess 30D is provided at the lower part of the opening and closing plates 30L, 30R, opposite the groove 30B. This recess 30D is a concave part that holds and retains the outflow body 2. To explain further, at the lower part of each of the opening and closing plates 30L, 30R, a perforation line L12 is provided in a concave shape that matches the cross-sectional shape of the opening 10 of the bag body 1. The recess 30D is formed by cutting along this perforation line L12.

[0026] <Aperture 300> Figure 3 shows the area around the opening 300 in the box body 3. Next, the opening 300 will be described with reference to Figures 1 and 3. As shown in Figure 1, the opening 300 is a roughly rectangular opening formed on one side of the box body 3. This opening 300 is located on the upper surface of the box body 3, which is the surface facing upwards when the outflow body 2 of the bag body 1 is protruding from the protrusion opening 30. Here, the surface facing upwards when the outflow body 2 of the bag body 1 is protruding from the protrusion opening 30 of the box body 3, that is, the upper surface of the box body 3 when in use, is the upper surface of the fluid packaging 100 when the fluid inside the fluid packaging 100 is released. As will be described in detail later, when releasing (removing) the fluid inside the fluid packaging 100, the outflow body 2 provided on the bag body 1 is protruding from the protrusion opening 30 of the box body 3. The surface of the box body 3 from which the outflow body 2 is protruding is oriented vertically, and the fluid packaging 100 is used facing the user. In this state, the outflow body 2 is positioned on the lower side of the box body 3. Also, in this state, the surface of the box body 3 that faces upwards is the upper surface. Hereafter, the top surface of this box 3 will be referred to as the top surface when in use.

[0027] Furthermore, it is preferable that the top surface of the box 3 when in use be the largest surface of the box 3. More specifically, it is preferable that the opening 300 be formed on the largest surface area of ​​the box 3. This makes it possible to secure a large area for the plate 4 provided inside the box 3. As a result, the bag 1 can be efficiently pressed through the plate 4.

[0028] Furthermore, it is preferable that the opening 300 of the box body 3 be located in the center of the top surface when in use. More specifically, it is preferable that the opening 300 be located opposite the center 41 of the plate surface of the plate body 4 (see Figure 4, described later). Furthermore, the opening 300 of the box body 3 is formed in the center of the top surface during use, and is sized to allow a typical person's hand (for example, a typical adult male) to be inserted along with their arm. This opening 300 ensures that the user can reliably press down on the center 41 of the plate body 4. Therefore, the opening 300 can be considered to have the function of guiding the position of the user's hand when pressing down on the plate body 4.

[0029] Now, the opening 300 shown in the figure is covered by a cover body 310 that is provided to open and close the opening 300. To explain this configuration in detail, first, a roughly H-shaped perforation line L3 (details will be described later) is provided in the center of the top surface of the box body 3 when it is in use, and the cover body 310 is formed by cutting along the perforation line L3 to open the opening.

[0030] Furthermore, the cover body 310 has a first body 311 and a second body 312 that are arranged side by side and can be opened and closed in the opening 300. The first body 311 has a protrusion 3111 that projects toward the second body 312 when it is arranged to close the opening 300 together with the second body 312. The second body 312 has a recess 3120 that receives the protrusion 3111.

[0031] The cover 310 is formed by attaching a perforation line L3 to the center of the top surface of the box body 3 when it is in use, and a portion of the top surface of the box body 3 is left as the cover 310 so that it can be opened and closed. Note that these H-shapes, U-shapes, and C-shapes are basic shapes and can be modified as appropriate depending on the overall shape adopted for the opening 300.

[0032] In this case, the cover 310 is formed by adding an H-shaped perforation line L3 to the center of the top surface of the box body 3 when it is in use, and comprises a first body 311 and a second body 312 that are formed to open and close in opposite directions like double doors. The first body 311 and the second body 312, which are two doors, are symmetrical with respect to the center of the opening 300, and are each formed as rectangles with approximately the same area. The first body 311 is rotatable in the vertical direction in Figure 3 about the edge of the opening 300 in the center of the top surface of the box body 3 when it is in use, and is capable of covering the upper area of ​​the opening 300 in the figure. The second body 312 is rotatable in the vertical direction in Figure 3 about the edge of the opening 300 in the center of the top surface of the box body 3 when it is in use, and is capable of covering the lower area of ​​the opening 300 in the figure. When the opening 300 is covered by the first body 311 and the second body 312, the opposing abutting edges 3113 and 3123 are brought together in the center of the opening 300. The abutted state of the first body 311 and the second body 312 is then fixed in place by the engagement of the abutting edges 3113 and 3123.

[0033] Furthermore, a protrusion 3111 is provided on one of the abutting edges 3113 and 3123 of the first body 311 and the second body 312, and a recess 3120 is provided on the other. In the illustrated example, the protrusion 3111 is formed in a semicircular convex shape, the recess 3120 is formed in a semicircular concave shape, and the protrusion 3111 is formed to a size that allows it to fit into the recess 3120. This prevents the relative positions of the first body 311 and the second body 312 from shifting. As a result, the unintentional opening of the first body 311 and the second body 312 is restricted.

[0034] <Plate 4> Figure 4 shows the schematic configuration of the plate body 4. Next, the general structure of the plate 4 will be described with reference to Figure 4. The plate 4 is formed as a flat body of a size that can press down on the bag 1 inside the box 3 from above. The plate 4 also has the rigidity to press down on the bag 1 from above. Preferably, this plate 4 has corners 43 that are positioned at each of the four corners of the internal space of the box 3. In other words, it is preferable that the plate 4 is the same size as or slightly smaller than the inner surface of the top of the box 3 when it is in use, and is formed as a flat plate of the same shape. In the illustrated example, the plate 4 is made of corrugated cardboard and is formed as a flat plate of the same shape as the inner surface of the top of the box 3 when it is in use, and is slightly smaller than the inner surface of the top of the box 3 when it is in use. Note that the shape of the corners 43 here is not particularly limited as long as it is a part that protrudes toward the corner of the internal space of the box 3. For example, the corners 43 may be square, or they may have a rounded tip (R-shaped). Also, the angles formed by the corners 43 may be right angles, acute angles, or obtuse angles.

[0035] <Blank Sheet S3> Figure 5 shows the configuration of the blank sheet S3 of the box body 3. Next, referring to Figure 5, the configuration of the blank sheet S3 of the box 3 will be explained. As described above, the box body 3 is formed by assembling the blank sheet S3. As shown in Figure 5, the blank sheet S3 consists of four side panels 31-34 and adhesive pieces 35, and a total of eight flaps 361, 371, 381, 391, 362, 372, 382, ​​and 392, four of which are connected to the upper and lower ends of the four side panels 31-34, one for each end.

[0036] The four side panels 31-34 are formed by connecting them horizontally in a single row, parallel to each other, via score lines, so that they can be assembled into a cylindrical shape. The adhesive piece 35 is formed by connecting it via a score line to one side edge of one of the four side panels 31. The four side panels 31-34 form the back panel 31, left side panel 32, front panel 33, and right side panel 34 when assembled to the box body 3. In this case, from left to right in Figure 5, they are the back panel 31, left side panel 32, front panel 33, and right side panel 34. In the illustrated example, the back panel 31 and front panel 33 are larger in dimensions than the left side panel 32 and right side panel 34. The adhesive piece 35 is formed by connecting it via a score line to one side edge of the back panel 31 opposite to the left side panel 32. In this case, the adhesive piece 35 is connected to one side edge of the back panel 31 and forms a narrow trapezoidal shape.

[0037] Of the eight flaps 361-391 and 362-392, the four flaps 361-391 connected to the lower ends of the four side panels 31-34 form the bottom lid when packaging the bag 1 after the box 3 has been assembled. These four flaps 361-391 consist of two inner flaps 371 and 391 and two outer flaps 361 and 381.

[0038] Of the eight flaps 361-391 and 362-392, the four flaps 362-392 connected to the upper ends of the four side panels 31-34 form the lid when packaging the bag 1 after the box 3 has been assembled. These four flaps 362-392 consist of two inner flaps 372 and 392 and two outer flaps 362 and 382.

[0039] Here, the two inner flaps 372 and 392 are each formed by connecting to the upper ends of one of the two opposing side panels, in this case the left side panel 32 and the right side panel 34, via a score line after the assembly of the four side panels 31-34. These inner flaps 372 and 392 are each formed in a plan view in an L-shape, large enough to cover approximately three-quarters of the top opening from the side panel side of the left side panel 32 and the right side panel 34 after the assembly of the four side panels 31-34.

[0040] In this case, each of the two inner flaps 372 and 392 is formed into a rectangle large enough to cover approximately half of the top opening from the left side panel 32 and right side panel 34, with half or more of the front panel 33 side portion being formed into a rectangle. Parts of these inner flaps 372 and 392 are folded over the top opening, so that their opposing ends abut against each other. The remaining half or nearly half of the two inner flaps 372 and 392 on the back panel 31 side is formed into a rectangle large enough to cover approximately half of the top opening from the left side panel 32 and right side panel 34, with the abutting ends having notches 3720 and 3920 on the other half being formed into a rectangle. The remaining parts of these inner flaps 372 and 392 are folded over the top opening, so that their opposing ends are separated. The notches 3720 and 3920 between these inner flaps 371 and 391 form an outlet 360 for removing the spilled material 2 from the bag 1 stored inside the box 3, and are formed to a size that makes it easy to remove the spilled material 2.

[0041] The two outer flaps 362 and 382 are each formed by connecting to the upper ends of the other two side panels, in this case the rear panel 31 and the front panel 33, which are opposite each other after the assembly of the four side panels 31-34, via score lines. These outer flaps 362 and 382 are each formed as rectangles in plan view, large enough to cover approximately half of the top opening from the rear panel 31 and front panel 33 sides after the assembly of the four side panels 31-34.

[0042] In this case, one outer flap 362 is formed as a rectangle large enough to cover the top opening from the upper edge of the rear panel 31 to a size slightly larger than half of it. The other outer flap 382 is formed as a rectangle large enough to cover the top opening from the upper edge of the front panel 33 to a size slightly smaller than half of it. This makes it possible to make the dimensions of the protruding opening 30 formed in the outer flap 362 larger.

[0043] In the blank sheet S3 configured in this way, the four side panels 31-34 are folded into a cylindrical shape (flat rectangular cross-section) via the scribed lines between the four side panels 31-34, and the adhesive piece 35 connected to the back panel 31 and the right side panel 34 are bonded together to assemble and fix the sheet into a cylindrical shape (flat rectangular cross-section).

[0044] Furthermore, the four flaps 361-391 that form the bottom cover are bent sequentially toward one end face that forms the bottom opening of the four side panels 31-34 after they have been assembled into a cylindrical shape, with the two inner flaps 371 and 391 and the two outer flaps 361 and 381 being bent toward one end face. Adhesive tape 9 (see Figure 1) is attached along the abutting ends of the two outer flaps 361 and 381 to close one end face of the four side panels 31-34, i.e., the bottom opening.

[0045] Furthermore, the four flaps 362-392 that form the top are bent sequentially toward the other end faces that form the top opening of the four side panels 31-34 after they have been assembled into a cylindrical shape, with the two inner flaps 372 and 392 and the two outer flaps 362 and 382 being bent toward the other end faces that form the top opening of the four side panels 31-34. Adhesive tape 9 (see Figure 1) is attached along the abutting ends of the two outer flaps 362 and 382, ​​closing the other end faces of the four side panels 31-34, i.e., the top opening. Thus, the box body 3 is assembled into a box shape that is long in one direction.

[0046] In such a box-shaped body 3, the protruding opening 30 is provided on an outer flap 362 that is connected to the upper end of the back plate 31. As previously described, the protruding opening 30 has an opening 30A for the outflow body 2 to protrude from the inside of the box-shaped body 3 to the outside of the box-shaped body 3, and a groove 30B at the lower edge of the opening 30A for receiving and holding the outflow body 2.

[0047] In this case, the opening 30A is made open in a roughly triangular shape at the center of the outer flap 362, with a horizontally oriented, modified H-shaped perforation line L1. The perforation line L1 consists of a first perforation line L11, a second perforation line L12, and a third perforation line L13. The first perforation line L11 forms the upper side of a roughly inverted triangle and is applied linearly in the horizontal direction in the figure. The second perforation line L12 is on the side opposite to the first perforation line L11 and forms a recess 30D, and is applied in a convex semicircle upward at the intersection of the other two sides of the roughly inverted triangle. The third perforation line L13 is provided in the center of the roughly inverted triangle so as to divide the roughly inverted triangle into two equal parts, and is applied linearly between the center of the first perforation line L11 and the center of the second perforation line L12. The other two sides of the roughly inverted triangle are represented by the grid line L10.

[0048] In this case, the groove 30B is formed by attaching perforations L2 and L12 in a circular shape at the lower, apex of the roughly inverted triangle along the perforation line L1. That is, a semicircular perforation line L2 is attached in a downwardly convex shape at the center of the lower edge of the opening 30A, and the groove 30B is formed in a downwardly convex shape by cutting out the inside of the perforation line L2 along this perforation line L2. This groove 30B becomes a receiving groove for the outflow body 2, and in this case, it has a size that allows the lower half of the cross-section of the mouth 10 of the bag body 1 to be fitted. In addition, a semicircular perforation line L12 is attached between the lower ends of the butt joints of the two opening and closing plates 30L and 30R that form the opening and closing section 30C, opposite to the groove 30B of the opening 30A, and a semicircular recess 30D is formed opposite to the groove 30B of the opening 30A by cutting out the inside of the perforation line L12 along this perforation line L12. This recess 30D serves as a retaining groove for the outflow body 2, and in this case, it is sized to accommodate the upper half of the cross-section of the opening 10 of the bag body 1. The recess 30D shown in the figure is a semicircle and is composed entirely of a curve, but it is not limited to this configuration. For example, a part of the recess 30D may be straight. To further explain, the central part of the second perforation line L12 may be formed in a straight line in the direction along the first perforation line L11 (horizontal direction in the figure). By forming the second perforation line L12 in a straight line, the opening and closing part 30C can more securely fix the outflow body 2.

[0049] The configuration of this protruding opening 30 does not particularly affect the rigidity of the box body 3 during storage and transportation as a fluid packaging body 100, nor does it affect its load-bearing strength when stacked in multiple layers; its rigidity and load-bearing strength are sufficiently maintained.

[0050] Furthermore, in such a box-shaped body 3, an opening 300 is provided in the front panel 33, which is the top surface of the box-shaped body 3 when in use. The opening 300 is formed into a rectangle by cutting along the perforations L3, which are H-shaped perforations L3 in the center of the front panel 33. In addition, a cover body 310 (first body 311 and second body 312) is formed in the opening 300.

[0051] In this case, a protrusion 3111 is provided on one of the abutting edges 3113 and 3123 of the first body 311 and the second body 312, and a recess 3120 is provided on the other. These protrusions 3111 and recess 3120 are formed to be mutually engageable. In the illustrated example, the protrusion 3111 is formed in a semicircular convex shape, the recess 3120 is formed in a semicircular concave shape, and the protrusion 3111 is formed to be sized to fit into the recess 3120.

[0052] Here, the abutting edges 3113 and 3123 of the first body 311 and the second body 312 extend in a direction along the outer flap 382 of the box body 3 (horizontal direction in the figure). That is, the abutting edges 3113 and 3123 extend in a direction along the horizontal direction in the fluid packaging 100 during transport. This prevents the opening 300 from unintentionally opening in the fluid packaging 100 when it is subjected to load during transport.

[0053] Due to the configuration of this opening 300, the rigidity of the box body 3 during storage and transportation as a fluid packaging body 100, and its load-bearing strength when stacked in multiple layers, are not affected, and its rigidity and load-bearing strength are sufficiently maintained.

[0054] Furthermore, the box body 3 is provided with hand holes 40 that serve as handles on the left side panel 32 and the right side panel 34, respectively. These hand holes 40 are formed by a linear score line drawn horizontally above the center of the left side panel 32 and the right side panel 34, and linear cut lines drawn upward from both ends of this score line. By pressing the area enclosed by these cut lines, the area within the cut lines is pushed into the box body 3, forming the hand holes 40, which serve as handles when transporting the fluid packaging 100.

[0055] Furthermore, the hand holes 40 are formed on the left side panel 32 and the right side panel 34, while the opening 300 is formed on the front panel 33. In other words, the hand holes 40 and the opening 300 are formed on different surfaces of the four side panels 31-34. This prevents the opening 300 from opening unintentionally when transporting the fluid packaging 100.

[0056] Here, we compare the areas of the handhole 40, the opening 300, and the front panel 33. The opening 300 is larger than the handhole 40 and smaller than the front panel 33. This ensures the rigidity of the box body 3 while allowing a hand to enter the inside of the box body 3 through the opening 300. Here, it is preferable that the area of ​​the opening 300 is 1 / 4 or less of the area of ​​the front panel 33. To elaborate further, it is preferable that the width W1 of the opening 300 is 1 / 2 or less of the width W2 of the front panel 33. Also, it is preferable that the height H1 of the opening 300 is 1 / 2 or less of the height H2 of the front panel 33. In the illustrated example, the height H1 of the opening 300 is 1 / 3 or less of the height H2 of the front panel 33.

[0057] <Packaging process> Figure 6 shows the fluid packaging process by the fluid packaging body 100. Next, the fluid packaging process using the fluid packaging body 100 will be explained with reference to Figure 6. Here, it is assumed that the bag 1 is filled with cosmetic material. The box 3 is assembled as described above by assembling and fixing the four side panels 31-34 into a cylindrical shape, and assembling the four flaps 361-391 that form the bottom lid by folding them into the bottom opening and fixing them in place. The four flaps 362-392 that form the top lid are not yet folded, and the top opening is open. The plate 4 is positioned along the front panel 33, which has an opening 300 (see Figure 1) inside the box 3.

[0058] From this state, the bag 1 filled with cosmetic is placed into the box 3 through the top opening. At this time, in order to prevent leakage of cosmetic from the outlet 2 of the bag 1, and to prevent the outlet 2 from being damaged by the weight of the cosmetic inside the bag 1, the bag 1 is placed inside the box 3 with the outlet 2 facing upwards. At this time, the plate 4 is sandwiched between the bag 1 inside the box 3 and the front panel 33 of the box 3. Also, the opening 300 formed in the front panel 33 of the box 3 is supported on the inside by the plate 4.

[0059] After the bag 1 is placed inside the box 3, the inner flaps 372, 392 and outer flaps 362, 382 that form the lid are successively folded over the top opening, closing the top opening (see arrows D11, D12, D13, and D14 in the figure). Then, adhesive tape 9 (see Figure 1) is attached between the abutting ends of the outer flaps 362, 382, ​​sealing the top opening (see Figure 1). As a result, the inner flaps 372, 392 and outer flaps 362, 382 are folded over the top opening surface of the box 3, sealing both end openings of the box 3. In this state where the top opening is closed, the outflow body 2 is located inside the box 3 and is not exposed to the outside of the box 3.

[0060] During storage and transport of the fluid packaging 100, in order to prevent leakage of the cosmetic product, the fluid packaging 100 is installed with the outlet 2 of the bag 1 facing upwards, that is, with the top of the box 3 facing upwards.

[0061] Thus, cosmetics using this fluid packaging 100 are provided. This cosmetic product comprises a bag 1 in which a fluid cosmetic composition is filled; an outlet 2 provided on the bag 1 and having an outlet 20 for discharging the cosmetic composition filled inside the bag 1; a box 3 that houses the bag 1 and has a protruding opening 30 for the outlet 20 of the housed bag 1 to protrude to the outside; and a plate 4 provided on the upper side of the bag 1 in the internal space of the box 3, with an opening 300 provided on the upper surface of the box 3 which faces upward, allowing the user to press the plate 4 through the opening 300.

[0062] <Usage process> Next, the process for using the cosmetic product packaged in the fluid packaging body 100 will be described. First, the fluid packaging 100 is transported in its packaged state as shown in Figure 1 above. Upon delivery to the user, the fluid packaging 100 undergoes two processes: an installation process, in which the outlet 2 is removed and installed, and an extrusion process, in which the cosmetic fluid is pushed towards the outlet 20. The details of the installation and extrusion processes are described below.

[0063] <Installation process> Figures 7 to 10 show the installation process of the fluid packaging body 100. The installation process of the fluid packaging body 100 will be explained with reference to Figures 7 to 10. First, as shown in Figure 7, in the box body 3, a perforated line L1 for the protruding opening 30 is formed on the large outer flap 362 on the top side. This perforated line L1 is pushed through by the user.

[0064] Next, as shown in Figure 8, the two opening / closing plates 30L and 30R are opened from the opening 30A in directions that separate them from each other (see arrows D21 and D22 in the figure). In addition, the semicircular groove 30B in the center of the lower edge of the opening 30A is cut out by the user, and the semicircular recesses 30D at the bottom of the abutting ends of each opening / closing plate 30L and 30R are cut out. In this way, the protruding opening 30 is opened. Behind this protruding opening 30 is the outlet 360 for the outflow body 2 between the two inner flaps 372 and 392, and the outside and inside of the box body 3 are connected through these protruding opening 30 and outlet 360.

[0065] Next, as shown in Figure 9, the outflow material 2 inside the box body 3 is pulled out to the outside of the box body 3 through the protruding opening 30. Then, the opening 10 of the bag body 1 is positioned (fitted) into the groove 30B of the protruding opening 30 of the box body 3, and the outflow material 2 is pushed out to the outside of the box body 3. Furthermore, from this state, the opening / closing part 30C is closed (see arrows D23 and D24 in the figure). At this time, the opening 10 of the bag body 1 is held in place by the recess 30D between the opening / closing plates 30L and 30R. In this way, the outflow material 2 is held and fixed in place.

[0066] Next, as shown in Figure 10, the box 3 is tilted (rotated) by the user. As a result, the lid from which the outflow body 2 protrudes from the protruding opening 30 is aligned vertically, and the front plate 33 with the opening 300 faces vertically upward as the top surface when in use. At this time, the top surface of the bag 1 also faces vertically, and this top surface becomes the front (side) when the fluid is in use. Furthermore, the position of the outflow body 2 in the box 3 is on the bottom side of the box 3, that is, the underside of the box 3. The underside of the box 3 refers to the area below the center of the box 3 in the vertical direction. To explain further, the position of the groove 30B in the box 3 is located on the underside of the box 3, that is, in the area below the center of the box 3 in the vertical direction. Furthermore, the outlet 2 and groove 30B in the box body 3 are each located at a position lower than half of the vertical length (height) of the box body 3, preferably lower than one-third, and more preferably lower than one-quarter.

[0067] When discharging the cosmetic from the bag 1 inside the fluid packaging 100 installed in this manner, the cock lever 21 of the discharge body 2 is rotated to open the spout. This causes the cosmetic to be dispensed from the outlet 20 by gravity and air pressure. The position of the discharge body 2 in the box 3 does not need to be on the bottom side of the box 3. For example, the position of the discharge body 2 may be on the bottom surface of the installed fluid packaging 100, rather than on the side surface.

[0068] <Extrusion Process> Figure 11 shows the process of opening the opening 300 during the extrusion process of the fluid packaging 100. Figure 12 shows the process of pressing the bag 1 during the extrusion process of the fluid packaging 100. Next, the extrusion process will be explained with reference to Figures 11 and 12. Here, the extrusion process is performed when the amount of cosmetic product contained in the bag 1 becomes low, when the user wants to increase the flow rate of the cosmetic product out of the bag 1, when they want to ensure that the cosmetic product flows out more reliably, or when the viscosity of the cosmetic product is high.

[0069] As shown in Figure 11, in the extrusion process, first, the user cuts open the top opening 300 along the perforation line L3 (see Figure 3). To open the opening 300, the user pushes through the perforation line L3 (see Figure 5) that forms the opening 300 on the top surface during use, i.e., the front plate 33. Then, the user places their fingers on the protrusion 3111 of the first body 311 of the cover body 310 and first pulls up the first body 311, followed by the second body 312 (see arrows D31 and D32 in the figure). In this way, as shown in Figure 11, by opening the first body 311 and the second body 312 vertically, the opening 300 is opened, and the outside and inside of the box body 3 are connected. This makes it possible to insert a hand into the inside of the box body 3 through the opening 300 and press the upward-facing side of the bag body 1 through the plate body 4 placed inside the box body 3.

[0070] Next, as shown in Figure 12, the user inserts their hand into the box 3 through the opening 300 and presses the bag 1 with their hand (see arrow D10 in the figure). This allows the bag 1 to be pushed (moved) towards the outlet 20 (see arrow D20 in the figure). In this case, as shown in Figure 12, the opening 300 is located on the top surface of the box 3 when in use and is oriented vertically upward. Therefore, in this box 3, the operation of pushing the fluid from the bag 1 by hand inside the box 3 is performed by the user inserting their hand through the opening 300 on the top surface of the box 3 when in use and pressing the bag 1 with their palm via the plate 4. This puts the user in a posture that makes it easy to put their weight on their hand using their shoulder as a pivot point. Consequently, the user can easily press the upward surface of the bag 1 with sufficient force using their palm.

[0071] Furthermore, since the bag body 1 is pressed via a plate 4, which is the size of a lid and is placed on top of the bag body 1 within the box body 3, the entire upward surface of the bag body 1 can be pressurized. Also, by pressing the bag body 1 via the plate 4, the bag body 1 can be pressurized evenly. In addition, since the corners 43 of the plate 4 are positioned in the corners of the internal space of the box body 3, the direction of movement of the plate 4 is guided. Therefore, the user can easily and reliably push out the fluid inside the bag body 1. As a result, the cosmetic product inside the bag body 1 can be efficiently pushed towards the outlet 2, and the cosmetic product can be smoothly poured out from the outlet 20 of the outlet 2.

[0072] <Effects and Effects> As described above, this fluid packaging 100 comprises a bag 1 in which a fluid is filled inside, an outlet 2 provided on the bag 1 for discharging the fluid filled inside the bag 1, a box 3 that houses the bag 1 and has a protruding opening 30 for the outlet 20 of the outlet 2 provided on the bag 1 to protrude to the outside, and a plate 4 provided on the upper side of the bag 1 in the internal space of the box 3, with an opening 300 provided on the upper surface of the box 3, which is the surface facing upwards from which the outlet 2 protrudes through the protruding opening 30.

[0073] In this way, the upper surface of the bag 1 can be easily pressed with sufficient force by hand inside the box 3, reliably pushing the fluid inside the bag 1 towards the outlet 2, and the fluid inside the bag 1 can be efficiently poured out from the outlet 20 of the outlet 2. Furthermore, since the user can press the plate 4 through the opening 300, the upper surface of the bag 1 can be easily pressed with sufficient force by hand inside the box 3, reliably pushing the fluid inside the bag 1 towards the outlet 20. As a result, the fluid inside the bag 1 can be efficiently poured out from the outlet 20. Furthermore, the plate 4 is located in the internal space of the box 3, above the bag 1, and is equipped with corners 43 positioned at each of the four corners inside the box 3. This allows the plate 4 to evenly press down on the entire upward surface of the bag 1 inside the box 3. As a result, the fluid inside the bag 1 can be moved to the outlet 20 more efficiently.

[0074] Furthermore, this fluid packaging 100 has the following advantages: (1) Since the box body 3 is equipped with a cover 310 that can be opened and closed to cover the opening 300, foreign matter can be prevented from entering the box body 3 and the inside of the box body 3 can be kept hygienic. In addition, the rigidity of the box body 3 can be maintained by covering and closing the opening 300 with this cover 310. (2) The cover body 310 includes a first body 311 and a second body 312 that are arranged side by side and can be opened and closed in the opening 300, so that the opening 300 can be opened and closed easily and reliably, and the effects of (1) above can be improved. In this case, the first body 311 is provided with a protrusion 3111, and the second body 312 is provided with a recess 3120. This ensures that the abutting ends of the first body 311 and the second body 312 engage securely, allowing the opening 300 to be opened and closed reliably, and further improving the effects of (1) described above. The protrusion 3111 also acts as a handle when opening and closing the cover 310, allowing the cover 310 to be opened and closed easily and reliably using this handle. Furthermore, the first body 311 can be tilted toward the protruding opening 30 side of the box body 3 (see arrow D31 in Figure 11). This allows a user facing the box body 3 to operate the discharge body 2 to reach into the opening 300 while holding the first body 311. The first body 311 also functions as a guide member to guide the user's hand. (3) In the box body 3, the top surface during use is the largest surface of the box body 3, and an opening 300 is provided on this large surface, so that the bag body 1 can be pressed with a large surface, and a large amount of fluid can be moved efficiently. In addition, since the opening 300 is provided in the center of the top surface during use, when the user presses the plate body 4 toward the bag body 1 by hand, the plate body 4 is less likely to tilt on the bag body 1, so that the plate body 4 can press the bag body 1 stably and evenly, and the fluid inside the bag body 1 can be moved more efficiently. Therefore, by making the top surface of the box 3 the largest surface on the box 3 when in use, and by providing an opening 300 in the center of this large surface, the bag 1 can be pressed evenly across the large surface, thereby further improving the fluidity.

[0075] <Variation> Figure 13 shows a modified example of the box body 3. Figure 14 shows a modified example of the plate body 4. Next, a modified example of this embodiment will be described with reference to Figures 13 and 14.

[0076] In the above embodiment, the opening 300 of the box 3 is provided in the center of the top surface of the box 3 when it is in use, but the opening 300 may also be provided on the outer edge side of the top surface of the box 3 when it is in use. In this case, it is possible to accommodate changes in the pressing position and method of pressing of the bag body 1 due to changes in the shape of some or all of the bag body 1, box body 3, and plate body 4. For example, if the opposite side (back side) of the bag body 1 from the outflow body 2 is to be pressed more heavily, the opening 300 should be placed on the back side of the top surface of the box body 3 when in use. By doing so, it is possible to achieve the same or even better effects as those in the above embodiment.

[0077] Furthermore, in the above embodiment, the opening 300 is rectangular, and the first body 311 and the second body 312 that open and close the opening 300 are symmetrical with respect to the longitudinal center of the opening 300, and are each formed as rectangles of the same size. In contrast, as shown in Figure 13(A), the first body 311 and the second body 312 may be asymmetrical, and one of the first body 311 and the second body 312 may be formed as a rectangle larger than the other. Needless to say, the opening 300 may also be square, and in this case as well, the first body 311 and the second body 312 may be symmetrical or asymmetrical, as described above. Moreover, the opening 300 may be circular, elliptical, oblong, or semi-oblong. For example, Figure 13(B) shows a particularly trapezoidal opening 300 and cover body 310 as examples, but the same applies to any shape, and the first body 311 and the second body 312 may each be two-part shapes of that shape, and may be symmetrical or asymmetrical.

[0078] Furthermore, in the above embodiment, a protrusion 3111 is provided on one of the abutting edges 3113 and 3123 of the first body 311 and the second body 312, and a recess 3120 is provided on the other. However, these protrusions 3111 and recesses 3120 may be provided in multiples, at equal or unequal intervals, on part or all of the abutting edges 3113 and 3123 of the first body 311 and the second body 312, at equal or unequal intervals.

[0079] Furthermore, although it has been explained that the convex portion 3111 and the concave portion 3120 are semicircular, their shapes are not particularly limited as long as they can engage with each other. For example, the shapes of the convex portion 3111 and the concave portion 3120 may be semi-elliptical, polygons such as squares and triangles, wavy, sawtooth (so-called jagged), etc.

[0080] Furthermore, as shown in Figures 13(A) and 13(B), the first body 311 and the second body 312 may be configured without the convex portion 3111 and the concave portion 3120.

[0081] In both the above embodiment and the above modified example, the opening 300 is provided by forming an H-shaped perforation line on one side panel (in this case, the front panel 33) of the box body 3, allowing the first body 311 and the second body 312 to be opened and closed. Alternatively, the opening 300 may be provided by forming a horizontal H-shaped perforation line on one side panel (in this case, the front panel 33) of the box body 3, allowing the first body 311 and the second body 312 to be opened and closed in the left-right direction.

[0082] In both the above embodiment and the above modified example, the opening 300 is provided by forming an H-shaped perforation line on one side panel of the box body 3 (in this case, the front panel 33), allowing the first body 311 and the second body 312 to open and close in the vertical direction. In contrast, as shown in Figure 13(C), the opening 300 may be provided by forming a U-shaped (or U-shaped) perforation line on one side panel of the box body 3, allowing one cover body 310 to rotate in one direction to open and close the opening 300.

[0083] Furthermore, the opening 300 of the box body 3 may be pre-cut, rather than being configured to be opened by the user along the perforation line L3 as described above. Alternatively, the opening 300 of the box body 3 may not be covered by the cover 310. In addition, although the opening 300 is described as being opened along the perforation line L3 during the extrusion process, the timing of opening the opening 300 is not particularly limited. For example, the opening 300 may be opened during the installation process.

[0084] In the above embodiment, the first body 311 and the second body 312 of the cover 310 were described as being pulled up, but the direction of movement of the first body 311 and the second body 312 is not particularly limited as long as the opening 300 can be formed. For example, one or both of the first body 311 and the second body 312 may be pushed down, that is, pushed inward toward the inside of the box 3.

[0085] In the above embodiment, the plate 4 is a flat plate of the same size as, or slightly smaller than, the inner surface of the top of the box 3 when it is in use, and has the same shape. Here, the shape of the plate 4 is not particularly limited. For example, the surface of the plate 4 may be circular, elliptical, polygonal, or other shapes. To further explain, the plate 4 may be configured to press only a part of the upper surface of the bag 1, rather than the entire upper surface.

[0086] Furthermore, as shown in Figure 14, the plate body 4 may have a projection 45 that protrudes toward the bag body 1 on the side that presses against the bag body 1, i.e., the bottom surface, on the side of the bag body 1 opposite to the side of the outflow body 2. This projection 45 has an inclined surface 47 that slopes toward the plate surface of the plate body 4 as it approaches the side of the outflow body 2. Note that the shape of the projection 45 is arbitrary as long as it can press against the side of the bag body 1 opposite to the outflow body 2 (the side facing inwards from the perspective of the outflow body 2). In this way, the fluid inside the bag 1 can be efficiently pushed out from the back side towards the outlet 2 when viewed from the outlet 2 side.

[0087] In the above embodiment, the fluid filled into the bag 1 was described as shampoo, but it is not limited to this. For example, the fluid filled into the bag 1 may be not only cosmetics (cosmetic compositions) such as shampoo, conditioner, body lotion, body soap, or emulsion, but also foods such as alcohol or seasonings, or chemicals such as fertilizers or adhesives. Furthermore, the fluid filled into the bag 1 is not limited to fluids such as cosmetics, foods, or chemicals, but may also be a solid such as granular material.

[0088] Although various embodiments and variations have been described above, these embodiments and variations can of course be combined to form a single structure. Furthermore, this disclosure is not limited in any way to the embodiments described above, and can be implemented in various forms without departing from the gist of this disclosure.

[0089] The fluid packaging 100 is an example of a cosmetic product. The box 3 and the plate 4 are examples of box assemblies. [Explanation of Symbols]
