[0011] Hereinafter, one embodiment of the present disclosure will be described in detail with reference to a schematic diagram of Fig. 1. Fig. 1 is a diagram for explaining an example of use of a packaging container 1 according to the present disclosure.

[0012] In addition, in describing one embodiment of the present disclosure, the following will be added: A numerical range expressed as "lower limit value XXX - upper limit value YYY" means equal to or greater than the lower limit value XXX and equal to or less than the upper limit value YYY. "Top" and "bottom" refer to the direction of gravity as the bottom side and the side opposite to the direction of gravity as the top side. "Inside" refers to the inside side of an object. "Outside" refers to the outside side of an object.

[0013] (Examples) For ease of understanding, first, with reference to FIG. 1, a usage example of a packaging container 1 according to the present disclosure will be described.

[0014] 1, the packaging container 1 is composed of a container set 2 and a storage container 20. The container set 2 is composed of a top surface portion 10 and a container holder 50. Therefore, the packaging container 1 is composed of the top surface portion 10, the storage container 20, and the container holder 50.

[0015] In the following description, the top surface portion 10 and the container holder 50 are described as separate items. However, the top surface portion 10 can also be said to be a part of the container holder 50 that functions as a lid for the opening 59 of the container holder 50.

[0016] First, the container holder 50 will be described. The container holder 50 is formed in a hollow cylindrical shape, and has an accommodation space 57 for accommodating the storage container 20 therein. The cylindrical shape may include various shapes such as a circular cross section, a polygonal cross section (rectangle, hexagon, etc.), an elliptical cross section, or an oval cross section. The container holder 50 has two holes 65a and 65b near the upper end. When the holes 65a and 65b are not distinguished from each other, they are referred to as holes 65. The holes 65 will be described later. The container holder 50 may have a bottom surface portion 58 at the lower end on which the storage container 20 can be placed.

[0017] 5 and 6, the container holder 50 includes a cylindrical or partly cylindrical sheet member (container body) 60 having an accommodation space for accommodating the storage container 20, and a cylindrical film member 70 attached to the outer wall surface of the sheet member 60. The above-mentioned hole 65 is formed in the sheet member 60. The film member 70 may or may not have a hole at a position corresponding to the hole 65 when attached to the outer wall surface of the sheet member 60.

[0018] Next, the storage container 20 may be a general storage container, and has a discharge section 21 for discharging the stored items. The discharge section 21 has a discharge port. The discharge section 21 is cylindrical, and a groove for attaching a cap may be formed on the outer wall surface. For example, the storage container 20 stores detergent, shampoo, rinse, food, etc. The storage container 20 may discharge the stored items using a dedicated cap having a discharge port, or may discharge the stored items without using the cap.

[0019] In the example shown in Fig. 1, the storage container 20 is a soft packaging container having a top gusset and a bottom gusset, and a discharge part 21 is attached to the center of the surface of the top gusset. The discharge part 21 is a spout. The discharge part 21 may be a resin molded product such as a spout, or may be formed from a part of the packaging material of the soft packaging container. In the example shown in Fig. 1, the storage container 20 is a shampoo dispenser (shampoo bottle) with a pump function used as a container for shampoo, rinse, etc.

[0020] 1, the top surface portion 10 is attached to the storage container 20. In the following example, the top surface portion 10 is described as being attached to the discharge portion 21 of the storage container 20.

[0021] 1, with the top surface portion 10 attached to the discharge portion 21 of the storage container 20, the storage container 20 is inserted into the housing space 57 of the container holder 50 from the direction shown in (A) in the figure. The container holder 50 may have any shape (height, width, opening shape, etc.) that can house the storage container 20.

[0022] 1, the top surface portion 10 is attached to the opening 59 of the container holder 50. At this time, the top surface portion 10 has a protrusion 16 on the side wall, and the top surface portion 10 is attached to the opening 59 so that the protrusion 16 can be inserted into a hole 65 of the container holder 50, as will be described in detail later. The hole 65 is formed at a position and with a size such that the protrusion 16 can be inserted when the top surface portion 10 is attached to the container holder 50.

[0023] Next, referring to the view indicated by reference number 140 in Fig. 1, the top surface portion 10 is attached to the opening 59 of the container holder 50, and with the protrusion 16 inserted into the hole 65, the top surface portion 10 is rotated leftward. A groove 17 is formed in the protrusion 16, and the hole edge that defines the hole 65 is inserted into the groove 17 by the rotation of the top surface portion 10. As a result, the protrusion 16 is engaged with the container holder 50.

[0024] With the above, the state in which the storage container 20 is held by the container holder 50 and the top surface portion 10 is completed.

[0025] In this state, the storage container 20 is attached to the opening 59 of the container holder 50, and the protrusion 16 is engaged with the hole 65. This reduces the possibility that the top surface 10 and the storage container 20 will fall off from the container holder 50, even if, for example, only the pump head 22 of the storage container 20 is grasped and the packaging container 1 is lifted upward. Alternatively, even if the container holder 50 is turned upside down while the body of the container holder 50 is grasped, it reduces the possibility that the top surface 10 and the storage container 20 will fall off from the container holder 50.

[0026] In Fig. 1, with reference to the view indicated by reference number 140, a configuration has been described in which the top surface portion 10 is rotated leftward and the hole edge defining the hole 65 is inserted into the groove 17 formed in the protrusion portion 16. However, even if the top surface portion 10 does not have the groove 17, a configuration in which the protrusion portion 16 is inserted into the hole 65 and engaged therewith may be considered, for example, in the case where the protrusion portion 16 and the hole 65 have substantially the same shape. Such a configuration is also included in the present disclosure.

[0027] An example of use of the packaging container 1 according to the present disclosure has been described above. Next, the top surface portion 10 and the container holder 50 will each be described in detail.

[0028] (Top part (1)) The top surface portion 10 according to the present disclosure will be described with reference to Fig. 2. Fig. 2 is a diagram for explaining the top surface portion 10 according to the present disclosure. Reference number 200 indicates a perspective view of the top surface portion 10. Reference number 210 indicates a rear view of the top surface portion 10. Reference number 220 indicates a side view of the top surface portion 10.

[0029] Referring to each diagram of FIG. 2, the top surface portion 10 includes a mounting portion 12, a side wall 13, and a protrusion portion 16. The top surface portion 10 may be formed by integrally molding the mounting portion 12, the side wall 13, and the protrusion portion 16 by injection molding or the like. The top surface portion 10 may be elastically deformable. In this case, when an external pressure is applied from the side wall 13 toward the mounting portion 12, the top surface portion 10 generates a repulsive force that pushes the side wall 13 in a direction away from the mounting portion 12. Due to the repulsive force generated by the top surface portion 10, the side wall 13 of the top surface portion 10 is pressed more strongly against the inner surface of the container holder 50, particularly when the inner diameter of the container holder 50 is smaller than the outer diameter of the top surface portion 10. This makes it difficult for the top surface portion 10 to come off the container holder 50, and makes it easier for the top surface portion 10 to be engaged with the opening 59 of the container holder 50. This is common to the top surface portions of the present disclosure (such as the top surface portion 30 and the top surface portion 40 described later). In the following description, it is assumed that the top surface portion 10 is integrally molded by injection molding or the like, and is configured to have the above-mentioned repulsive force.

[0030] The mounting portion 12 is attached to the discharge portion 21 of the storage container 20. With reference to the view indicated by reference number 200 in Fig. 2, the mounting portion 12 is a portion in which part of the side wall 13, which is circular in plan view, is cut out, and is formed so that the discharge portion 21 of the storage container 20 can be inserted therein. The mounting portion 12 is composed of a first step 12a, a second step 12b, and a wall surface 12c.

[0031] The first step 12a narrows the insertion width of the discharge portion 21 from the side wall 13 toward the center of the top surface portion 10. Although the first step 12a is not essential to the top surface portion 10, it makes it easier to insert the discharge portion 21 of the storage container 20 into the mounting portion 12. The second step 12b is formed slightly larger than the outer diameter of the discharge portion 21 and engages the discharge portion 21 inserted into the mounting portion 12. The second step 12b is provided to surround point C, which is the center of the top surface portion 10, and functions as a locking portion that locks the discharge portion 21.

[0032] The wall surface 12c is a curved wall erected on the plate-like members constituting the first stage 12a and the second stage 12b, and erected so as to surround a part of the periphery of the first stage 12a and the second stage 12b. The wall surface 12c is connected to the side wall 13 via one or more ribs 14.

[0033] The rib 14 connects the side wall 13 and the wall surface 12c, and functions as a reinforcing material that enhances the strength of the top surface portion 10. However, the rib 14 does not have to be provided on the top surface portion 10. In the example shown in FIG. 2, there are three ribs 14, one of which connects the apex of the convex shape of the wall surface 12c to the side wall 13 in a plan view, and the other two are located at positions 90 degrees on both sides from the apex, and connect the wall surface 12c to the side wall 13. However, the position of the rib 14 is not particularly limited. There may be any number of ribs 14, one or more. Compared to a case where the entire top surface of the top surface portion 10 is molded from resin, the rib 14 has the effect of significantly reducing the amount of resin required to manufacture the top surface portion 10. Therefore, the top surface portion according to the present disclosure is in line with the sustainable circular economy required by the SDGs (Sustainable Development Goals), which is a global trend, and can also greatly contribute to reducing plastic waste.

[0034] When the storage container 20 with the mounting portion 12 attached to the discharge portion 21 is accommodated in the accommodation space 57 of the container holder 50, at least a portion of the side wall 13 abuts against the inner surface of a sheet member 60 (described later) constituting the container holder 50. As an example, the side wall 13 is composed of a first side wall 13a, a second side wall 13b, and a third side wall 13c. Each part will be described below with reference to the diagram indicated by reference number 220 in FIG. 2.

[0035] The first side wall 13a is located at the upper end of the side wall 13. When the top surface portion 10 is attached to the opening 59, the lower surface of the first side wall 13a is placed on the upper end of the opening 59 of the container holder 50, preventing the top surface portion 10 from falling into the opening 59. However, it is also assumed that the top surface portion 10 does not fall into the opening 59 when, for example, the outer diameter of the storage container 20 and the inner diameter of the opening 59 are approximately the same diameter. Therefore, the side wall 13 does not necessarily have to include the first side wall 13a. The first side wall 13a is connected to the second side wall 13b below it.

[0036] The second side wall 13b abuts against the inner surface of the opening 59 of the container holder 50. The second side wall 13b may have a length of, for example, 5 mm to 20 mm. The second side wall 13b is connected to the third side wall 13c at its lower portion.

[0037] The third side wall 13c is inclined toward the center of the opening 59 so that the diameter becomes smaller in order to facilitate attachment of the top surface portion 10 to the opening 59 of the container holder 50. The third side wall 13c has an outer circumferential diameter at its lower end that is, for example, about 10 mm smaller than the outer circumferential diameter of the second side wall 13b. The third side wall 13c is provided with a protrusion 16a and a protrusion 16b. When there is no need to distinguish between the protrusion 16a and the protrusion 16b, they are referred to as the protrusion 16.

[0038] The side wall 13 may not include the third side wall 13c. When the side wall 13 does not include the third side wall 13c, the protrusion 16 may be provided on the second side wall 13b.

[0039] The side wall 13 can also be described as follows: The side wall 13 includes a contact portion (second side wall 13b) that contacts the inner surface of the container body 60, and an inclined portion (third side wall 13c) that inclines from the contact portion toward the center of the container body 60, and the protrusion 16 is provided on the inclined portion.

[0040] 2, the protrusion 16 is composed of a protrusion 16a and a protrusion 16b. The protrusion 16 protrudes outward from the side wall 13 (the second side wall 13b or the third side wall 13c). There may be one protrusion 16, but there are preferably multiple protrusions 16, and more preferably the protrusions 16 are arranged at equal intervals on the circumference of an imaginary circle corresponding to the opening 59 of the container holder 50. This allows the load of the storage container 20 to be distributed evenly (approximately evenly) to the container holder 50, and the storage container 20 can be stably accommodated in the container holder 50.

[0041] The protrusion 16 is preferably located below the side wall 13. This is because the protrusion 16 is engaged in the hole 65, and the distance from the upper end of the sheet member 60 to the hole 65 is long due to the protrusion 16 being located below the side wall 13. This makes it possible to reduce the occurrence of tearing of the sheet member 60 between the upper end of the sheet member 60 and the hole 65.

[0042] FIG. 2 shows the XYZ coordinate system. Referring to the diagram indicated by reference number 210 in FIG. 2, as an example, the protrusion 16a protrudes from the side wall 13 in the X-axis direction (left direction in the drawing) outward and bends downward along the Y-axis. As a result, a groove 17a is formed between the protrusion 16a and the side wall 13. The protrusion 16b protrudes from the side wall 13 in the X-axis direction (right direction in the drawing) outward at a position opposite the protrusion 16a across point C and bends upward along the Y-axis. As a result, a groove 17b is formed between the protrusion 16b and the side wall 13. When the grooves 17a and 17b are not distinguished from each other, they are referred to as the groove 17. The protrusion 16 is not limited to a configuration having the groove 17 between the side wall 13 and the protrusion 16, and the groove 17 may be formed in the protrusion 16 itself. In this way, the formation of the groove 17 due to the presence of the protrusion 16 can also be expressed as the protrusion 16 having the groove 17.

[0043] The protrusion 16 has the groove 17, which provides the following effect. With reference to the diagram indicated by reference number 140 in FIG. 1, the top surface 10 is attached to the opening 59 of the container holder 50, and the protrusion 16 is inserted into the hole 65, and the top surface 10 is rotated leftward (clockwise). Since the protrusion 16 has the groove 17, the edge of the hole that defines the hole 65 of the sheet member 60 is inserted into the groove 17 by the rotation of the top surface 10. As a result, the edge of the hole 65 is inserted into the groove 17 of the protrusion 16 from a direction perpendicular to the axial direction of the container holder 50 (the up-down direction in FIG. 1), and the protrusion 16 is engaged with the container holder 50 (or the sheet member 60) at the hole 65. The protrusion 16 may have the groove 17 so that the edge of the hole that defines the hole 65 of the sheet member 60 is inserted into the groove 17 by rotating the top surface 10 rightward (counterclockwise).

[0044] According to the above-mentioned configuration, even if the pump head 22 of the storage container 20 is pulled in the same direction as the axial direction of the container holder 50, the engagement between the protrusion 16 and the sheet member 60 is unlikely to be released. In addition, by making the width of the groove 17 slightly larger than the thickness of the hole edge that defines the hole 65, the engagement between the protrusion 16 and the sheet member 60 can be further strengthened.

[0045] 2, the bent portion of the protrusion 16 extending in the Y-axis direction passes through the hole 65 of the container body and is positioned outside the container body 60 (more specifically, between the container body 60 and the film 70) at the periphery of the hole 65. This makes it possible to suppress deformation of the container body 60 in a direction in which the protrusion 16 comes out of the hole 65 when the container body 60 is flexible, and as a result, it is also possible to suppress the protrusion 16 from falling off from the hole 65.

[0046] The engagement of the projection 16 with the hole 65 will be described later with reference to FIG.

[0047] (Top part (2)) The top surface portion 30 according to the present disclosure will be described with reference to Fig. 3. Fig. 3 is a diagram for explaining the top surface portion 30. Reference number 300 indicates a perspective view of the top surface portion 30. Reference number 310 indicates a plan view of the top surface portion 30. Reference number 320 indicates a side view of the top surface portion 30.

[0048] 3, the top surface 30 includes a mounting portion 32, a side wall 33, and a protrusion 36. Here, the mounting portion 32 and the side wall 33 may be the same as the mounting portion 12 and the side wall 13 of the top surface 10, respectively. Therefore, a description of the mounting portion 32 and the side wall 33 will be omitted, and the protrusion 36 will be described below.

[0049] FIG. 3 shows the XYZ coordinate system. Referring to the diagrams shown by reference numbers 300 and 320 in FIG. 3, in the top surface portion 30, the protrusion 36a protrudes from the side wall 33 toward the outside, which is the downward direction of the Z axis. A groove 37a is formed between the protrusion 36a and the side wall 33. The protrusion 36b also protrudes from the side wall 33 toward the outside, which is the downward direction of the Z axis. A groove 37b is formed between the protrusion 36b and the side wall 33. When the grooves 37a and 37b are not distinguished from each other, they are referred to as the groove 37. The protrusion 36 is not limited to a configuration having the groove 37 between the side wall 33, and the groove 37 may be formed in the protrusion 36 itself. In this way, the formation of the groove 37 due to the presence of the protrusion 36 can be expressed as the protrusion 36 having the groove 37.

[0050] Protrusion 36 has groove 37, which provides the following effect. With top surface 30 attached to opening 59 of container holder 50 and protrusion 36 inserted into hole 65, top surface 30 is pushed downward (in the direction of gravity). Because protrusion 36 has groove 37, the action of pushing top surface 30 downward causes the hole edge that defines hole 65 in sheet member 60 to be inserted into groove 37. As a result, protrusion 36 is engaged with container holder 50 at hole 65. By making groove 37 slightly wider than the thickness of the hole edge that defines hole 65, the engagement between protrusion 36 and sheet member 60 can be further strengthened.

[0051] (Top part (3)) The top surface portion 40 according to the present disclosure will be described with reference to Fig. 4. Fig. 4 is a diagram for explaining the top surface portion 40. Reference number 400 indicates a perspective view of the top surface portion 40. Reference number 410 indicates a plan view of the top surface portion 40. Reference number 420 indicates a side view of the top surface portion 40.

[0052] The top surface portion 40 includes a mounting portion 42, a side wall 43, a rib 44, and a protrusion portion 46. Each component will be described below.

[0053] (Mounting part) With reference to the drawings indicated by reference numbers 400 and 410 in Fig. 4, the mounting portion 42 is mounted to the discharge portion 21 of the storage container 20. In the example of Fig. 4, the mounting portion 42 is formed in a C-shape in a plan view so as to fit into the discharge portion 21 of the storage container 20, and the discharge portion 21 (not shown) of the storage container 20 is inserted from a cut-out portion. The mounting portion 42 may have elasticity, and when the discharge portion 21 is inserted from the cut-out portion, the cut-out portion widens, making it easier to insert the discharge portion 21.

[0054] It is preferable that the mounting part 42 has a shape corresponding to the discharge part 21. For example, when the cross section of the discharge part 21 is circular, the portion of the mounting part 42 that is mounted to the discharge part 21 is configured to be circular. When the cross section of the discharge part 21 is rectangular, the portion of the mounting part 42 that is mounted to the discharge part 21 is configured to be rectangular.

[0055] 4, the mounting portion 42 may have a wall surface 42a so as to be in contact with the discharge portion 21 over a larger area. By having the wall surface 42a, the mounting portion 42 can more stably mount the discharge portion 21 and can easily maintain the C-shape.

[0056] The mounting portion 42 may have a step 42b on the lower side of the wall surface 42a. The step 42b is a step (surface) that abuts against the lower side of the discharge portion 21 and holds the discharge portion 21 when the mounting portion 42 is mounted with the discharge portion 21. The step 42b extends from the wall surface 42a in a direction perpendicular to the wall surface 42a. The length of extension may be adjusted as appropriate.

[0057] The mounting portion 42 is connected to the side wall 43 via a rib 44 .

[0058] (side wall) The side wall 43 is engaged with the opening 59 of the cylindrical container holder 50 when the storage container 20 with the mounting portion 42 attached to the discharge portion 21 is accommodated in the opening 59 of the cylindrical container holder 50. The side wall 43 is composed of at least two side walls separated from each other. The at least two side walls 43 are arranged at equal intervals on the circumference of an imaginary circle corresponding to the opening 59 of the container holder 50. Therefore, in the example of FIG. 4, the two side walls 43 are located on opposite sides across the mounting portion 42. When the side wall 43 is composed of three side walls separated from each other, the three side walls are arranged at equal intervals (120° intervals) on the circumference of an imaginary circle corresponding to the opening 59 of the container holder 50. This allows the load of the storage container 20 to be distributed evenly (almost evenly) to the container holder 50, and the storage container 20 is stably accommodated in the container holder 50.

[0059] The at least two side walls 43 do not necessarily need to be disposed at equal intervals on the circumference of an imaginary circle corresponding to the opening 59 of the container holder 50, and may be designed to have an appropriate interval therebetween.

[0060] 4, the side wall 43 includes a first side wall 43a, a second side wall 43b, and a third side wall 43c. Each part will be described below.

[0061] The first side wall 43a is placed on the opening edge of the container holder 50 when the storage container 20, with the mounting portion 42 attached to the discharge portion 21 of the storage container 20, is accommodated in the opening 59 of the container holder 50. The first side wall 43a is connected to the second side wall 43b at its lower side.

[0062] The second side wall 43b contacts the inner wall surface of the container holder 50 when the first side wall 43a is placed on the opening edge of the container holder 50. When the container holder 50 is upright on a table or the like, the second side wall 43b is preferably parallel (approximately parallel) to the inner wall surface of the container holder 50 and in close contact with the inner wall surface. This allows the side wall 43 to be more firmly attached to the container holder 50. The second side wall 43b may have a length of, for example, 5 mm to 20 mm. The second side wall 43b is connected to the third side wall 43c at its lower part.

[0063] The third side wall 43c is inclined toward the center of the opening 59 so that the diameter becomes smaller in order to facilitate attachment to the opening 59 of the top surface portion 40. The third side wall 43c has an outer circumferential diameter at its lower end that is, for example, about 10 mm smaller than the outer circumferential diameter of the second side wall 43b. The third side wall 43c is provided with a protrusion 46a and a protrusion 46b. When there is no need to distinguish between the protrusion 46a and the protrusion 46b, they are referred to as the protrusion 46.

[0064] The side wall 43 may not include the third side wall 43c. When the side wall 43 does not include the third side wall 43c, the protrusion 46 is provided on the second side wall 43b.

[0065] The protrusion 46 may be provided on the second side wall 43b, or may be provided on the boundary between the second side wall 43b and the third side wall 43c. In the following description, it is assumed that the protrusion 46 is provided on the third side wall 43c. The protrusion 46 is composed of a protrusion 46a and a protrusion 46b. The protrusion 46 protrudes outward from the side wall 43. Although not shown in FIG. 4, the protrusion 46 may have a groove formed therein for inserting a hole edge that defines the hole 65 of the sheet member 60.

[0066] In FIG. 1, assuming that the top surface portion 40 is used instead of the top surface portion 10, the top surface portion 40 has the protrusions 46, and thereby provides the following effects.

[0067] With the top surface portion 40 attached to the opening 59 of the container holder 50, the protrusion 46 is further inserted into the hole 65. As an example, the hole 65 is formed slightly larger than the protrusion 46, so that the inserted protrusion 46 fits tightly into the hole 65.

[0068] This reduces the possibility that the top surface 40 and the storage container 20 will fall off from the container holder 50, even if, for example, only the pump head 22 of the storage container 20 is grasped and the storage container 20 is lifted upward. Or, even if the container holder 50 is turned upside down while the body of the container holder 50 is grasped, it reduces the possibility that the top surface 40 and the storage container 20 will fall off from the container holder 50. In this way, the side wall 43 has the protrusions 46 to be more firmly engaged with the container holder 50.

[0069] With reference to the diagram indicated by reference number 420 in FIG. 4, the protrusion 46a may have a bent portion (not shown) that bends to one side in the Y-axis direction. The protrusion 46b may have a bent portion (not shown) that bends to the other side in the Y-axis direction. With this configuration, when the container body 60 is flexible, it is possible to suppress deformation of the container body 60 in a direction in which the protrusion 46 comes out of the hole 65, and as a result, it is possible to suppress the protrusion 46 from falling off from the hole 65. The bent portion may be provided not in the protrusion 46 but in the first side wall 43a.

[0070] Above, the top surface portion having various shapes has been described. The present disclosure is not limited to the above-mentioned top surface portion, but includes other top surface portions having similar functions. In addition, the position, direction, size, etc. of the groove formed in the protrusion portion are not particularly limited as long as the hole edge of the container holder 50 can be inserted therein.

[0071] (rib) 4, the rib 44 is a member for connecting the mounting portion 42 and the side wall 43. The rib 44 may be formed of a member separate from the mounting portion 42 and / or the side wall 43, or may be formed integrally with the mounting portion 42 and the side wall 43. Here, the rib 44 is assumed to be formed integrally with the mounting portion 42 and the side wall 43 by injection molding or the like.

[0072] In Fig. 4, there are two ribs 44, one on each side of the mounting portion 42. The two ribs 44 are provided, although not limited thereto, in line symmetry with respect to the center of a line connecting both ends of the cut-out portion of the mounting portion 42 formed in a C-shape and a line connecting the center of the mounting portion 42. More specifically, the pair of ribs 44 are formed in line symmetry with respect to the center of the line connecting both ends of the cut-out portion of the mounting portion 42 and the line connecting the center of the mounting portion 42, and extend in a direction perpendicular to the line. The two ribs 44 extend in a direction (extension line of the ribs 44) that passes through the center of the mounting portion 42, and are provided in point symmetry with respect to the center of the mounting portion 42.

[0073] In addition, it is preferable that the height of the rib 44 when viewed from the front is greater than the width when viewed from the top. This is because a load is more likely to be applied to the rib 44 in the height direction than in the width direction, and the strength of the rib 44 in the direction in which the load is more likely to be applied is increased.

[0074] The shape of the rib 44 is not important as long as it functions to connect the mounting portion 42 and the side wall 43. However, the rib 44 may have an arch structure used in bridges and the like to increase strength in a direction in which a load is likely to be applied. Arch structures are known to be characterized by being less prone to bending and having small deflection behavior. The arch structure of the rib 44 increases the load-bearing characteristics, and can maintain strength against a downward load applied by a user even when the storage container 20 has a pump function.

[0075] (Container holder) Next, a description will be given of the container holder 50 according to the present disclosure. The container holder 50 is composed of a sheet member 60 and a film member 70. The sheet member 60 and the film member 70 will be described below with reference to Figs. 5 and 6.

[0076] (Sheet material) 5 is a diagram for explaining a sheet member 60 according to the present disclosure. Reference numeral 500 indicates an elevational view of the sheet member 60. Reference numeral 510 indicates a development view of the sheet member 60. Reference numeral 520 indicates a perspective view of the sheet member 60.

[0077] 5, the sheet member 60 has a storage space 67 for storing the storage container 20 and is formed in a cylindrical shape. The sheet member 60 may be synthetic resin, paper, synthetic paper, or a laminate thereof. The sheet member 60 may have a degree of rigidity that allows it to be deformed by the stress of the film member 70 described below. As an example, the sheet member 60 is polyethylene terephthalate (PET). The thicker the sheet member 60, the stronger the strength of the container holder 50 can be. The sheet member 60 may have a thickness of, for example, 100 μm to 400 μm. Preferably, the sheet member 60 has a thickness of 200 μm to 300 μm.

[0078] With reference to the diagram indicated by reference number 510 in Fig. 5, the sheet member 60 may have a shape such as a square, a rectangle, a trapezoid, or a sector before being formed into a cylindrical shape. The sheet member 60 may have a shape such as a polygonal prism, a cylinder, or a truncated cone when being formed into a cylindrical shape. In the following description, the sheet member 60 is assumed to have a sector shape before being formed into a cylindrical shape, and a truncated cone shape after being formed into a cylindrical shape.

[0079] The term "sector" refers to a figure surrounded by a pair of arcs and radii drawn at both ends of the arcs. In this specification, the term "sector" includes a shape that is approximately a sector. This also applies to cases where the sheet member 60 has a square, rectangular, trapezoid, or other shape before being formed into a cylindrical shape, and to cases where the sheet member 60 has a cylindrical or truncated cone shape, or other shape after being formed into a cylindrical shape.

[0080] The sheet member 60 will now be described in detail.

[0081] Referring to the drawing indicated by reference number 500, the sheet member 60 has a first end 62a and a second end 62b. The first end 62a and the second end 62b each have a shape corresponding to a portion of a circular arc, and the first end 62a is shorter than the second end 62b.

[0082] The sheet member 60 may have a fold line 62c that is configured by a fold line, a half-cut line, or the like, extending from the first end portion 62a to the second end portion 62b. The sheet member 60 may have one or more fold lines 62c. In the example of FIG. 5, the sheet member 60 has one fold line 62c. By having the fold line 62c, the sheet member 60 can be easily folded. This allows the sheet member 60 to be transported or packaged, and the container holder 50 to be manufactured efficiently.

[0083] Referring to the view indicated by reference numeral 510, the sheet member 60 has a side edge 62d and a side edge 62e. The side edges 62d and 62e may overlap each other when the sheet member 60 is folded at the fold line 62c.

[0084] The sheet member 60 may have an adhesive piece 64 near the center of the side end 62d (or the side end 62e). The adhesive piece 64 may be formed by extending from the side end 62d (or the side end 62e) of the sheet member 60 integrally with the sheet member 60, and providing an adhesive portion on at least a part of the extending portion. The adhesive piece 64 adheres the side end 62d and the side end 62e folded at the folding line 62c to each other. The adhesive piece 64 may adhere the side end 62d and the side end 62e to each other by overlapping them, or may form the sheet member 60 into a cylindrical shape by providing a distance between the side end 62d and the side end 62e. When the sheet member 60 is formed into a cylindrical shape by providing a distance between the side end 62d and the side end 62e, it can be expressed that the sheet member 60 forms a part of a cylindrical shape. The adhesive portion of the adhesive piece 64 may be a hot melt adhesive, an adhesive tape, a glue, or the like.

[0085] The sheet member 60 has a hole 65 between the first end 62a and the second end 62b in the vicinity of the second end 62b which constitutes the open end of the sheet member 60. The size, shape, or position of the hole 65 is determined so that the protrusion 16 of the top surface portion 10, the protrusion 36 of the top surface portion 30, or the protrusion 46 of the top surface portion 40 can be engaged therewith.

[0086] The view indicated by reference number 520 shows the state after the side ends 62d and 62e have been adhered to one another by the adhesive piece 64 and the sheet member 60 has been formed into a cylindrical shape. The adhesive piece 64 is located near the center between the first end 62a and the second end 62b and does not have to extend all the way to the first end 62a and the second end 62b.

[0087] In the above description, the sheet member 60 is, for example, polyethylene terephthalate (PET) and is flexible. The flexibility of the sheet member 60 allows the shape of the sheet member 60 (particularly the opening of the sheet member 60) to be flexibly changed to match the shape of the side wall of the top surface portion 10. Therefore, the container holder 50 can be applied to top surfaces of various shapes.

[0088] However, other materials (such as plastic, metal, wood, paper, film, glass, or a combination thereof) having a similar shape and function may be used instead of polyethylene terephthalate (PET) for the sheet member 60. As an example, instead of polyethylene terephthalate (PET), a molded product of plastic or glass may be used for the sheet member 60.

[0089] (Film material) Next, a method for obtaining the container holder 50 from the film member 70 according to the present disclosure and the sheet member 60 and the film member 70 will be described with reference to Fig. 6. Fig. 6 is a diagram for explaining the method for obtaining the container holder 50 from the sheet member 60 and the film member 70.

[0090] The diagram indicated by reference number 600 shows a state in which a cylindrically formed sheet member 60 has an accommodation space 67 therein and a mandrel 80 (core) is inserted into the accommodation space 67. As an example, the mandrel 80 is reduced in diameter as it goes upward. The sheet member 60 is inserted into the mandrel 80 from the second end portion 62b side.

[0091] The diagram indicated by reference number 610 shows a state in which the film member 70 is placed over the sheet member 60 inserted into the mandrel 80. The film member 70 is a tubular, stretchable or heat-shrunk member that is attached to the outer wall surface (side surface) of the sheet member 60. The film member 70 may be a shrink film, a stretch film, a wrap-around label, a tack label, or the like. The film member 70 may be wrapped around the tubular sheet member 60 to form a tubular shape. In the following description, the film member 70 will be described as a shrink film.

[0092] The inner surface of one end of the cylindrical film member 70 may be joined (center sealed) to the outer surface of the other end by adhesive or welding. The thickness of the film member 70 is not particularly limited, but may be, for example, 10 to 120 μm. When the film member 70 is a shrink label, the thickness of the film member 70 is preferably, for example, 12 to 60 μm.

[0093] A shrink label is a film that is heat-shrinkable at least in a first direction. A heat-shrinkable film is a film that does not shrink at room temperature (e.g., 23°C) but has the property of shrinking in a predetermined direction when heated to a heat-shrinkage temperature (e.g., 80°C to 100°C). A film that is heat-shrinkable at least in a first direction is a film that has heat-shrinkability at least in the first direction. For heating, an appropriate method such as hot air, steam, superheated steam, or LED irradiation can be used. The shrinkage rate of the film member 70 is, for example, 15 to 90%, and preferably 20 to 85%, of the shrink film in the first direction at 90°C for 10 seconds. The heat-shrinkage rate of the shrink film in the second direction at 90°C for 10 seconds is -3 to 15%, and preferably -1 to 10%.

[0094] The first direction means one direction in the plane of the film, and the second direction means a direction perpendicular to the first direction in the plane of the film. For example, in the case of a cylindrical film member 70, the long axis direction of the cylindrical shape (the axial direction of the cylindrical film member 70) can be defined as the second direction, and the direction perpendicular to the second direction (the circumferential direction) can be defined as the first direction.

[0095] Various films can be used for the film member 70, provided that they have the above-mentioned thermal properties. Examples of materials for the film member 70 include synthetic resin films, nonwoven fabric films, and foamed resin films. The film member 70 may be a laminated film containing at least one material selected from the above-mentioned materials. The laminated film may be a laminate of a film that is substantially not heat-shrinkable and a film that has heat-shrinkability, provided that the laminate as a whole has heat-shrinkability, but a laminate made entirely of films that have heat-shrinkability is preferred.

[0096] Preferably, a synthetic resin film or a laminated film having a synthetic resin layer is used as the film member 70, and more preferably, a single-layer synthetic resin film or a multi-layer synthetic resin film is used. A single-layer synthetic resin film is a film made of a single synthetic resin layer, and a multi-layer synthetic resin film is a laminated film in which two or more synthetic resin layers are laminated.

[0097] The material of the synthetic resin film (synthetic resin layer) is not particularly limited, and may be one or a mixture of two or more selected from the following thermoplastic resins: polyester-based resins such as polyethylene terephthalate and polylactic acid; olefin-based resins such as polyethylene, polypropylene, and cyclic olefin; polystyrene-based resins such as polystyrene and styrene-butadiene copolymer; polyamide-based resins; and vinyl chloride-based resins. The material of the nonwoven fabric film and the foamed resin film is also not particularly limited, and may be one using a conventionally known synthetic resin. The nonwoven fabric film and the foamed resin film themselves can be expected to have a heat insulating effect.

[0098] The film member 70 may be a self-stretching stretch label that does not require heat, instead of a shrink label. The film member 70 can maintain the outer shape of the sheet member 60 by the function of the shrink label or stretch label.

[0099] The film member 70 may have a dividing line (such as a perforation). The container holder 50 can change the shape of the sheet member 60 from a cylindrical shape to a flat shape by dividing the film member 70 at the dividing line. In other words, the sheet member 60 can be configured to return to its original shape. The sheet member 60 may be configured to return to its original shape by the hand of a human or machine, or may be configured to return to its original shape naturally.

[0100] The film member 70 may be bonded to the sheet member 60 via an adhesive portion. In this case, the film member 70 is integrated with the sheet member 60.

[0101] The film member 70 can be subjected to design printing to improve the decorativeness of the container holder 50. Specifically, the film member 70 can be subjected to gravure printing, flexographic printing, inkjet printing, screen printing, or the like to improve the decorativeness of the container holder 50 compared to the case where a design is printed directly on a resin molded product.

[0102] The diagram indicated by reference number 620 shows a state after the film member 70 has been placed over the sheet member 60. In the illustrated example, in the axial direction of the mandrel 80, the film member 70 is longer than the sheet member 60 and protrudes from a first end 62a (not shown) of the sheet member 60.

[0103] The diagram indicated by reference number 630 shows the completed container holder 50 after the film member 70 has been heat-shrunk by an appropriate method such as hot air, steam, superheated steam, or LED irradiation. In the illustrated example, the container holder 50 has the heat-shrunk film member 70 attached to the outer wall surface of the sheet member 60, and the film member 70 forms part of the bottom surface portion 58 of the container holder 50. By heat-shrinking the film member 70, the container holder 50 can maintain the outer shape of the sheet member 60.

[0104] The container holder 50 may have a tapered portion 56 between a pair of ends in the axial direction of the sheet member 60, the diameter of which gradually decreases toward the bottom portion 58. This allows a plurality of container holders 50 to be stacked in the vertical (height) direction. With this configuration, a plurality of container holders 50 can be stacked in the vertical (height) direction for storage and transportation, and the storage efficiency and transportation efficiency can be increased by the number of stacked container holders. However, the container holder 50 does not have to have the tapered portion 56.

[0105] The container holder 50 does not necessarily have to have a bottom surface portion 58. In other words, the top surface portion 10 and the like may be attached to an opening of a cylindrical container holder 50 that does not have a bottom surface portion 58, and may be a component that constitutes the top surface of the container holder 50. If the container holder 50 does not have a bottom surface portion 58, then in the step indicated by reference numeral 620, the sheet member 60 and the film member 70 do not need to protrude from the upper surface of the mandrel 80 in the axial direction of the mandrel 80.

[0106] Container holder 50 may have a configuration other than sheet member 60 and film member 70, and is not particularly limited as long as it has a cylindrical portion with an opening.

[0107] As described above, the container holder 50 can reduce the amount of resin used compared to conventional container holders manufactured by injection molding. Therefore, the container holder according to the present disclosure is in line with the sustainable circular economy required by the global trend of SDGs (Sustainable Development Goals), and can also greatly contribute to reducing plastic waste.

[0108] Furthermore, the container holder 50 provides the following effects.

[0109] Consider a container holder that can be used for a wide variety of containers, such as containers with the same shape but different flavors or limited-edition products. In the case of a conventional container holder manufactured by resin molding, if information related to the contents of the container is directly printed on the container holder, the inventory of the container holder increases when sales of the container decrease.

[0110] In contrast, with the container holder 50, information related to the contents of the storage container can be printed on the film member 70. In other words, the label design of the film member 70 can be changed according to the contents of the storage container, and the film member 70 can be attached to the sheet member 60. This allows the inventory of container holders 50 themselves to be significantly reduced compared to the past.

[0111] Furthermore, while conventional container holders require a mold for resin molding, container holder 50 can be easily manufactured using sheet member 60 and film member 70, eliminating the need for the mold that was previously required.

[0112] In this manner, the container holder can provide a variety of effects.

[0113] (Engagement of the protrusion with the hole) Next, using the top surface portion 10 as an example, a manner in which the protrusion 16 of the top surface portion 10 is locked into the hole 65 of the container holder 50 will be described with reference to FIG. 7. FIG. 7 is a diagram showing a manner in which the protrusion 16 is locked into the hole 65 of the container holder 50. The diagram indicated by reference number 700 is a perspective view showing a state in which the hole 65 of the container holder 50 is inserted into the groove 17 of the protrusion 16. The diagram indicated by reference number 710 is a cross-sectional view showing a state in which the hole edge 66 of the hole 65 of the container holder 50 is inserted into the groove 17 of the protrusion 16. For ease of understanding, the film member 70 is not shown in the diagram indicated by reference number 700.

[0114] With reference to reference number 700 in Fig. 7 and reference number 140 in Fig. 1, the top surface portion 10 is attached to the opening 59 of the container holder 50 and the protrusion 16 is inserted into the hole 65, and then the top surface portion 10 is rotated leftward (clockwise). Since the protrusion 16 has a groove 17, the rotation of the top surface portion 10 causes the hole edge 66 that defines the hole 65 of the sheet member 60 to be inserted into the groove 17. As a result, the protrusion 16 is engaged with the container holder 50 (or the sheet member 60) at the hole 65.

[0115] Next, referring to the diagram indicated by reference number 710 in Fig. 7, the sheet member 60 has a hole 65, but the film member 70 does not have a hole at a position corresponding to the hole 65. In other words, the hole 65 is covered by the film member 70. Therefore, the protrusion 16 may push up the film member 70 in a convex shape with the hole edge 66 inserted into the groove 17, thereby forming a convex portion 70a on the film member 70. According to the above configuration, a user of the packaging container 1 can visually confirm that the protrusion 16 is engaged with the hole 65 through the formation of the convex portion 70a.

[0116] Furthermore, since the protrusion 16 enters the recess on the inside of the film member 70 created by the formation of the convex portion 70a, it is less likely to come out of the recess and is more strongly engaged with the film member 70. At this time, the protrusion 16 is pressed by the film member 70 toward the inside of the container holder 50, so that the bent portion at the tip of the protrusion 16 is firmly clamped between the film member 70 and the hole edge 66. As a result, the protrusion 16 is more strongly engaged with the hole edge 66 and the film member 70.

[0117] It is not necessary for the protrusion 16 to be pressed against the film member 70 so as to form the convex portion 70a on the film member 70. In other words, it is sufficient for the protrusion 16 to be in contact with the film member 70. The protrusion 16 being in contact with the film member 70 means that the protrusion 16 is inserted into the hole 65. This generates a frictional force between the protrusion 16 and the film member 70, and the engagement with the container holder 50 can be strengthened.

[0118] As described above, the hole 65 may be covered by the film member 70. This eliminates the need to provide an opening in the film member 70 in accordance with the hole 65, and allows the structure of the container holder 50 to be simplified.

[0119] Furthermore, the film member 70 may have a printed layer (not shown) at a position covering the hole 65. This makes the presence of the hole 65 less visible when the container holder 50 is viewed from the outside due to the printed layer, thereby improving the aesthetics and design of the container set. The printed layer may be a shielding printed layer containing a white pigment such as titanium oxide or a silver pigment such as aluminum paste, thereby making the hole 65 invisible.

[0120] The above describes the configuration in which the protrusion 16 of the top surface portion 10 is engaged with the hole 65 of the container holder 50, using the top surface portion 10 as an example. The same configuration can be applied to the other top surface portions according to the present disclosure.

[0121] 〔summary〕 A container set according to aspect 1 of the present disclosure is a container set comprising a cylindrical container holder for accommodating a storage container, and a top surface portion attached to the opening of the container holder, wherein the container holder comprises a cylindrical or partial cylindrical container body having a storage space for accommodating the storage container, and a cylindrical film member attached to the outer wall surface of the container body, wherein the container body has one or more holes in the wall surface forming the opening, and the top surface portion comprises an attachment portion attached to the storage container, a side wall at least a portion of which abuts against the inner surface of the container body when the storage container with the attachment portion attached is accommodated in the opening of the container holder, and one or more protrusions protruding outward from the side wall, and each of the one or more protrusions engages with the container holder at any one of the one or more holes.

[0122] According to the above configuration, in the container set according to the first aspect of the present disclosure, when the storage container is stored in the opening of the container holder, at least a part of the side wall of the top surface part abuts against the inner surface of the container body, so that the storage container can be easily stored in the storage space of the container holder. Furthermore, each of the one or more protrusions is engaged with the container holder at one or more holes. This reduces the possibility of the container holder and the top surface part becoming disengaged due to the impact that the container set receives from the ground when dropped.

[0123] The container set according to aspect 2 of the present disclosure is similar to aspect 1 above, in that the one or more protrusions are present in multiple locations and are equally spaced from one another around the circumference of an imaginary circle corresponding to the opening of the container holder.

[0124] According to the above-mentioned configuration, the one or more protrusions are provided in a plurality of portions, and the load of the storage container can be distributed evenly (approximately evenly) to the container holder, whereby the storage container is stably stored in the container holder.

[0125] The container set according to a third aspect of the present disclosure is the container set according to the first or second aspect, wherein the one or more holes are covered with the film member.

[0126] According to the above configuration, the one or more holes can be covered with the film member, and the one or more protrusions can be engaged with the container holder at any one of the one or more holes, which eliminates the need to provide openings in the film member to match the one or more holes, thereby simplifying the structure of the container holder.

[0127] A container set according to a fourth aspect of the present disclosure is the container set according to the third aspect, wherein the film member has a printed layer at a position covering the one or more holes.

[0128] According to the above configuration, the printing layer makes it difficult to see the presence of the one or more holes when the container holder is viewed from the outside, thereby improving the aesthetics and design of the container set.

[0129] The container set according to a fifth aspect of the present disclosure is the container set according to the third or fourth aspect, wherein the one or more protrusions contact the film member at the positions of the one or more holes.
