Description

Technical Field

[0001] The present invention relates to a holder for accommodating and holding an article.

Background Art

[0002] Conventionally, for example, in order to accommodate and hold an article such as a cup container containing a beverage or food, a cup holder that is used by folding and assembling a single sheet body is known (see Patent Document 1). This cup holder includes a top surface portion provided with a cup holding opening that allows insertion of the lower region of the cup container, a bottom surface portion on which the cup container is placed, and front, rear, left, and right side surface portions that are connected so that the top surface portion and the bottom surface portion face each other in a separated state. In addition, between the top surface portion and the bottom surface portion, four reinforcing pieces are provided. These reinforcing pieces are provided to maintain a three-dimensional state in which the top surface portion and the bottom surface portion are separated and face each other, and these reinforcing pieces are formed by providing four cuts in the side surface portion and folding them back. However, such a cup holder requires a large area of the sheet body because it has side surface portions on the front, rear, left, and right, resulting in high costs. In addition, the operation of folding the side surface portions is complicated. Further, in order to maintain a three-dimensional state in which the top surface portion and the bottom surface portion are separated and face each other, it is necessary to fold four reinforcing pieces, and there is a problem that the assembly work is complicated.

Mode for Carrying Out the Invention

[0014] As shown in FIG. 5, the holder 1 according to the present embodiment is a holder that holds and uses a cup containing a beverage by accommodating the cup in the accommodating portion 20 when carrying the cup. This holder 1 is formed by folding and assembling the unfolded sheet 2 shown in FIG. 1 and first making it into the state of a primary assembled part as shown in FIG. 4. The state of the primary assembled part refers to a state in which the unfolded sheet 2 is subjected to bending or pasting and stored flat. And when in use, as shown in FIG. 2, the side plates 11 and the intermediate side plates 13 stand up with respect to the bottom plate 12 to form a rectangular tube shape.

[0015] The holder 1 is formed by assembling the unfolded sheet 2 shown in FIG. 1. Although the holder 1 in the present embodiment is formed of a cardboard sheet, it may be formed of a plate-like member such as paperboard.

[0016] First, the configuration of the unfolded sheet 2 of the holder 1 will be described according to FIG. 1. FIG. 1 shows the inner surface of the holder 1 on the front side of the paper surface.

[0017] The top plate 10 is a part that constitutes the top of the holder 1 and is formed in a rectangular shape. At the front and rear edges of the top plate 10, side plates 11 that constitute the side portions of the holder 1 are continuously provided via bent portions 100 that combine a cut 301 and a score line 302. In the present embodiment, the length from the front end to the rear end of the side plate 11 is 35 mm. At the front and rear edges of the side plate 11 on the side opposite to the side where the top plate 10 is continuously provided, a bottom plate 12 that constitutes the bottom of the holder 1 is continuously provided via a bent portion 100 that combines a cut 301 and a score line 302. At the edge of the front bottom plate 12 on the side opposite to the side where the side plate 11 is continuously provided, an intermediate side plate 13 is continuously provided via a bent portion 100 that combines a cut 301 and a score line 302. Also, at the edge of the intermediate side plate 13 on the side opposite to the side where the bottom plate 12 is continuously provided, an adhesive plate 14 is continuously provided via a bent portion 100 that combines a linear cut 301 and a score line 302, and a substantially U-shaped cut.

[0018] Further, the unfolded sheet 2 forms a break portion 200 by continuous short cuts 301 extending from the center in the left-right direction of the front edge of the adhesive plate 14 to the center in the left-right direction of the rear edge of the rear bottom plate 12. When the number of cups to be accommodated is two or less, if this break portion 200 is broken, the main body of the holder 1 can be divided into two, and the accommodating portions 20 can be used as two holders 1.

[0019] Also, a substantially U-shaped notch is provided at the rear edge of the rear bottom plate 12 on the extension of the break portion 200. Furthermore, a circular through-hole 15 is formed on the broken portion 200 in the bent portion 100 between the front bottom plate 12 and the intermediate side plate 13. This through-hole 15 is used to raise the side plate 11 from the bottom plate 12 to form a rectangular tube shape by placing a finger on it, to hold the holder 1, or to make it easier to break the broken portion 200.

[0020] The top panel 10 has four storage compartments 20 formed therein. In this embodiment, two storage compartments 20 are formed on the front side of the top plate 10 in a symmetrical shape. Additionally, two storage compartments 20 are formed on the rear side of the top plate 10 in a symmetrical shape. The front storage compartments 20 are formed in a front-to-back symmetrical shape with respect to the rear storage compartments 20. Details of the storage compartment 20 will be explained with reference to Figure 3 for the rear right storage compartment 20, and the explanation for the other storage compartments 20 will be omitted.

[0021] The storage section 20 has an edge portion 21 formed by the bent portion 100. This bent portion 100 is constructed by combining a cut 301 and a pressed line 302. The edge portion 21 is octagonal in shape, formed by the first side portion 22, the first inclined portion 23, the second side portion 24, and the second inclined portion 25. In this embodiment, the distance between the front and rear first sides 22, the distance between the left and right second sides 24, and the distance between the opposing first inclined portion 23 and second inclined portion 25 are set to 70 mm.

[0022] The first side portion 22 is the front and back opposing side portion of the octagon. The first rear edge portion 22 is formed by a notch 301 along the bend between the top plate 10 and the rear side plate 11. The front first side portion 22 is formed by a bent portion 100 consisting of cuts 301 from the side adjacent to the left and right second inclined portions 25 and a pressed line 302 in the central part of the first side portion 22. Furthermore, the first side flap 26 is formed via this bent portion 100. The first side flap 26 is formed by a roughly trapezoidal cut 301 on the inside of the edge 21 from the bent portion 100. The first side flap 26 is formed with a curve such that the free end side is recessed towards the first side 22. The length of the first side flap 26 from the first side 22 to the most recessed curved portion of the free end edge is approximately the same as the length of the right-side first inclined flap 27 from the first inclined portion 23 to the most recessed curved portion of the free end edge.

[0023] The first inclined portion 23 is the left and right side portions that extend diagonally outward from the left and right ends of the rear first side portion 22. The first inclined portion 23 on the left side is formed by a bent portion 100 consisting of cuts 301 from the side adjacent to the upper edge 22 and the side adjacent to the second edge 24, and a pressed line 302 in the central part of the first inclined portion 23. The first inclined portion 23 on the right side is formed by a bent portion 100 consisting of a short cut 301 located slightly spaced from the side adjacent to the upper edge 22, a cut 301 coming from the side adjacent to the second edge 24, and a creasing line 302 in the central part of the first inclined portion 23. Furthermore, the first inclined flap 27 is formed via this bent portion 100. The first inclined flap 27 is formed by a roughly trapezoidal cut 301 on the inside of the edge 21 from the bent portion 100. The first inclined flap 27 is formed with a curve such that the free end side is recessed towards the first inclined portion 23. The length of the right first inclined flap 27 from the first inclined portion 23 to the most recessed curved portion of the free end edge is shorter than the length of the left first inclined flap 27 from the first inclined portion 23 to the most recessed curved portion of the free end edge, and is approximately the same length as the length of the first side flap 26 from the first side portion 22 to the most curved recessed portion of the free end edge. Furthermore, the notch 301 that forms the first inclined flap 27 has a connecting portion T of approximately 0.5 mm near the roughly trapezoidal corner (see illustration).

[0024] The second inclined portion 25 is the edge portion of the second edge portion 24 that extends diagonally inward from the end opposite to the side where the first inclined portion 23 is continuous, and reaches the front first edge portion 22. The left and right second inclined portions 25 are formed by a bent portion 100 consisting of cuts 301 from the side adjacent to the second side portion 24 and the side adjacent to the first side portion 22, and a pressed line 302 in the central part of the second inclined portion 25. Furthermore, the second inclined flap 28 is formed via this bent portion 100. The second inclined flap 28 is formed by a roughly trapezoidal cut 301 on the inside of the edge 21 from the bent portion 100. The second inclined flap 28 on the left side is formed to be vertically symmetrical with the first inclined flap 27 on the left side. The second inclined flap 28 on the right side is formed to be horizontally symmetrical with the second inclined flap 28 on the left side. The notch 301 that forms the second inclined flap 28 has a connecting portion T of approximately 0.5 mm near the roughly trapezoidal corner (see illustration).

[0025] The second side portion 24 is the left and right side portion, extending linearly from the end opposite to the side where the left and right first inclined portions 23 are continuous with the rear first side portion 22, toward the front, and reaching the left and right second inclined portions 25. The second side portion 24 is formed by a bent portion 100 consisting of a pressed line 302 adjacent to the first inclined portion 23 and the second inclined portion 25, and a cut 301 in the central part of the second side portion 24. Furthermore, a reinforcing flap 29 is formed via this bent portion 100. The reinforcing flaps 29 are formed in the shape of the sheet portion on the inside of the edge portion 21, excluding the first side flap 26, the first inclined flap 27, and the second inclined flap 28. A central cut 301 extends from the left-right center of the rear first side portion 22 to the left-right center of the front first side portion 22, forming the right reinforcing flap 29 and the left reinforcing flap 29. Furthermore, the length from the second side portion 24 of the reinforcing flap 29 to the free edge is set to 35 mm, making it the same length as the front-to-back length of the side plate 11. The portion of the reinforcing flap 29 formed by the notch 301 that constitutes the first rear edge portion 22 forms a side edge portion 30 that contacts the side plate 11 when an item is stored in the storage portion 20 and the reinforcing flap 29 hangs down toward the bottom plate 12. Furthermore, the portion of the reinforcing flap 29 formed by the central cutout 301 forms a bottom edge 31 that follows the bottom plate 12 when an item is placed in the storage section 20 and the reinforcing flap 29 hangs down towards the bottom plate 12. Furthermore, the side portion 30 and the base portion 31 form a right-angle corner portion 32. Furthermore, this central cutout 301 has connecting sections T of approximately 0.7 mm near the center and on the front and rear sides.

[0026] Before using holder 1, as described above, the first inclined flap 27 and the reinforcing flap 29, the second inclined flap 28 and the reinforcing flap 29, and the right reinforcing flap 29 and the left reinforcing flap 29 are connected by the connecting part T, preventing them from coming apart and getting caught on each other during production work, which would harm the work.

[0027] Next, we will explain the process of preparing the unfolded sheet 2 to represent the primary assembly. As shown in Figure 4(a), the bent portion 100 between the front side plate 11 and the bottom plate 12 is bent, adhesive is applied to the adhesive plate 14, and it is attached to the inside of the top plate 10. Then, as shown in Figure 4(b), adhesive is applied to the rear end of the rear bottom plate 12, the bent portion 100 between the rear side plate 11 and the top plate 10 is bent, and it is attached to the outside of the front bottom plate 12 to form a flattened primary assembly. Figure 4(c) shows the primary assembly from Figure 4(b) from the top plate 10 side.

[0028] To complete the assembly from this initial assembly state, the side plates 11 are raised relative to the base plate 12, causing the intermediate side plates 13 to also rise in conjunction, forming a rectangular tube shape and completing the assembly process, resulting in the state shown in Figure 2. At this time, the bent portions 100 between the top plate 10 and the side plate 11, the bent portions 100 between the side plate 11 and the bottom plate 12, the bent portions 100 between the bottom plate 12 and the intermediate side plate 13, and the bent portions 100 between the intermediate side plate 13 and the adhesive plate 14 are formed by combining the cuts 301 and the pressed lines 302. As a result, the bending resistance of the sheet is weaker than if the bent portions were formed using only the pressed lines 302, making assembly easier. In this state, the side plates 11 and intermediate side plates 13 are prone to collapsing because there is nothing to support them upright, and they tend to return from a rectangular cylindrical shape to a flattened state.

[0029] This section explains how to use this holder 1. In this embodiment, two cups are housed in the holder 1. Therefore, the left side, which is not needed, is broken at the break section 200 and used in separate pieces. As shown in Figure 5, the large cup is housed on the rear right side of the holder 1, and the small cup is housed on the front right side.

[0030] First, let's explain the rear storage compartment 20. A large cup is stored in this compartment 20. The height of the side plate 11 of the cup holder 1 from the bottom plate 12 to the storage area 20 is 35 mm, and the diameter of the cup at a height of 35 mm from the bottom of the large cup is 68 mm.

[0031] In the state where the holder 1 has been assembled, as described above, the storage section 20 is connected to the first inclined flap 27 and the reinforcing flap 29, and to the second inclined flap 28 and the reinforcing flap 29 by connecting parts T. Also, the right reinforcing flap 29 and the left reinforcing flap 29 are connected by connecting parts T. Even in this state, if a cup is pushed into the storage section 20 from above, the connecting section T will easily break, and the bent section 100 between the first side section 22 and the first side flap 26, the bent section 100 between the first inclined section 23 and the first inclined section flap 27, the bent section 100 between the second inclined section 25 and the second inclined section flap 28, and the bent section 100 between the second side section 24 and the reinforcing flap 29 will bend. The connecting section T is formed to a length of 0.5 to 0.7 mm as described above so that it can be easily broken by pushing a cup into it without having to break it by hand during use. Also, at this time, the bent section 100 is designed to bend with little resistance due to the combination of the cut 301 and the press line 302. The distance between the front and rear first sides 22, the left and right second sides 24, and the distance between the first inclined section 23 and the second inclined section 25 is 70 mm, and the diameter near the cup-sized storage section 20 is 68 mm. Therefore, the first side flaps 26, the first inclined section flaps 27, the second inclined section flaps 28, and the reinforcing flaps 29 are pushed down by the cup-sized object, hanging almost vertically towards the bottom plate 12, causing the storage section 20 to open and the cup-sized object to be stored inside.

[0032] When a cup-sized object is placed in the storage compartment 20, as shown in Figures 6 and 7(a), the reinforcing flap 29 is bent at the folding portion 100 and hangs down almost vertically towards the bottom plate 12, with the straight side portion 30 in contact with the inner surface of the side plate 11. Furthermore, the straight base portion 31 is in contact with the bottom plate 12. Furthermore, the right-angle corner 32, formed by the side portion 30 and the bottom portion 31, fits into the corner between the bottom plate 12 and the side plate 11. In this way, the reinforcing flap 29 maintains its rectangular tubular shape robustly by restricting the movement of the side plate 11 in the direction of collapse, as its straight edge portion 30 is in contact with the inner surface of the side plate 11. Furthermore, the reinforcing flap 29 has a straight edge, the bottom portion 31, that contacts the bottom plate 12, creating a bracing effect between the top plate 10 and the bottom plate 12, improving its strength against pressure, and also restricting the movement of the side plate 11 in the direction of collapse, thereby firmly maintaining the rectangular tubular shape. Furthermore, the right-angled corners 32 fit into the corners between the bottom plate 12 and the side plates 11, further restricting the movement of the side plates 11 in the direction of tilting, thereby maintaining the assembled state of a rectangular cylindrical shape.

[0033] Next, we will describe the front storage compartment 20. A small cup is stored in this storage compartment 20. The height from the bottom plate 12 of the side plate 11 of the cup holder 1 to the storage compartment 20 is 35 mm, and the diameter of the small cup at a height of 35 mm from the bottom of the cup is 56 mm.

[0034] When storing the small cup in the storage section 20, if the small cup is pushed in from above the storage section 20 as described above, the bent portion 100 between the second side 24 and the reinforcing flap 29 will bend. In addition, the bent portion 100 between the first side 22 and the first side flap 26, the bent portion 100 between the first inclined portion 23 and the first inclined portion flap 27, and the bent portion 100 between the second inclined portion 25 and the second inclined portion flap 28 will bend in accordance with the location where the small cup is pressed. In this embodiment, in addition to the reinforcing flap 29, the left and right first inclined portion flaps 27 are also bent. At this time, as shown in Figures 6 and 7(b), the storage section 20 has a distance of 70 mm between the front and rear first sides 22, between the left and right second sides 24, and between the opposing first inclined section 23 and second inclined section 25. In contrast, the diameter of the cup at a height of 35 mm from the bottom of the small cup is 56 mm. Therefore, in this state, the reinforcing flap 29 hangs diagonally from the bent portion 100 of the second side 24 towards the bottom plate 12, and the bottom edge 31 does not touch the bottom plate 12. However, when the top plate 10 is pressed, the top plate 10 becomes slightly concave, and the bottom edge 31 of the reinforcing flap 29 abuts against and conforms to the bottom plate 12, improving its strength against pressure.

[0035] Furthermore, similar to the state when the large cup is placed inside, the straight edge portion 30 of the side plate 11 is in contact with the inside of the side plate 11, restricting the movement of the side plate 11 in the direction of tilting, and firmly maintaining the assembled state of the rectangular tube shape.

[0036] Thus, even without providing side panels on the front, back, left, and right as in conventional designs, the holder 1 can be constructed using only a pair of front and rear side panels 11, while still maintaining a robust assembled state. This reduces the amount of corrugated cardboard used and keeps costs down. Furthermore, since assembly is completed simply by raising the side panels 11 from the bottom panel 12 when in use, there is no need to stock pre-assembled units, and it can be stored in a small space. It also eliminates the trouble of pre-assembling stock units. The folding section 100 is composed of a notch 301 and a creasing line 302, and the resistance when folding is appropriately adjusted to facilitate assembly. Furthermore, the length of the connecting section T is set to 0.5 to 0.7 mm, allowing for easy breakage simply by pressing the object into it.

[0037] The technical concept of this invention is not limited to the embodiments described above. For example, a configuration like the holder 3 shown in Figures 8 to 10 also produces the same effect as described above. Similar to holder 1, holder 3 is formed by folding the unfolded sheet 4 shown in Figure 8 and attaching the bottom plates 12 together to create a flattened primary assembly, which then takes on a rectangular cylindrical shape when in use. The edge 21 of the housing section 20 of the holder 3 has a reinforcing flap 129 connected via a bent section 100 (pressed line 302), and the rest of the portion is formed by a cut 301. The front storage section 20 is connected to a reinforcing flap 129 via a left-side folding section 100 (pressed line 302). The rear storage section 20 is connected to a reinforcing flap 129 via a right-side folding section 100 (pressed line 302). A bent portion 100 (with a cut 301 and a creasing line 302) is formed in the center of the reinforcing flap 129.

[0038] Then, as shown in Figures 9 and 10, when the cup is pushed into the storage section 20, the reinforcing flap 129 hangs down towards the bottom plate 12, and the reinforcing flap 129 bends into an approximately L-shape at the bent portion 100 (cut 301 and press line 302) formed in the center, with the bent free end portion overlapping the bottom plate 12. In this case, the bent portion 100 formed in the center of the reinforcing flap 129 forms the base portion 131, producing the same effect as described above. In this embodiment as well, the straight side portion 130 is in contact with the inside of the side plate 11, and the right-angled corner portion 132 fits into the corner between the bottom plate 12 and the side plate 11, restricting the movement of the side plate 11 in the direction of tilting down and maintaining the assembled state of a rectangular tube.
