Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above-described holder, the inner case that functions as a heat conductor has the inner surface of the holder body, and a part of the heat conductor is heated by a Peltier element that functions as a heater. Therefore, when the beverage container is heated to a predetermined temperature, there is a possibility that only the portion in contact with the heater is excessively heated on the inner surface of the holder body that can be touched by the user's hand.

Means for Solving the Problems

[0005] A beverage container holding device for solving the above problems is configured to heat a beverage container. The beverage container holding device includes a resin-made holder that holds the beverage container inside the holder, a sheet-like heat conductor located outside the holder and having a higher thermal conductivity than the holder, a planar heating element located outside the heat conductor and smaller than the heat conductor, and a heat insulator that covers the planar heating element outside the planar heating element.

[0006] According to the beverage container holding device described above, the heat of the planar heating element is transmitted to the beverage container through a heat conductor larger than the planar heating element and a resin holder. At this time, since the heat conductor diffuses the heat of the planar heating element and the resin holder diffuses the heat of the heat conductor, the heat of the planar heating element is transmitted to the beverage container over a wide range through the diffusion of the heat conductor and the holder. Further, the resin holder suppresses the direct transmission of the heat of the beverage container to the heat conductor and diffuses the heat of the beverage container within the resin holder. Such heat diffusion by the resin holder suppresses the non-uniformity of the temperature distribution in the heat conductor and favorably promotes the diffusion of the heat of the planar heating element described above. As a result, the heat insulation of the heat insulating body and the diffusion of the heat of the planar heating element are combined to achieve uniform heating over a wide range of the beverage container, and excessive temperature rise in a local range occupied by the planar heating element can be suppressed.

[0007] In the beverage container holding device described above, the holder may include a cylindrical peripheral wall surrounding the beverage container, and an outer surface of the peripheral wall may be in contact with the heat conductor. According to this beverage container holding device, since heating is performed so as to surround the beverage container, it can be suitably heated over the entire beverage container.

[0008] In the beverage container holding device described above, the heat conductor may include a plurality of heat transfer sheets. According to this beverage container holding device, since the area of each heat transfer sheet is smaller than the case where the heat conductor includes only one heat transfer sheet, the handling of the heat transfer sheet is easy.

[0009] In the beverage container holding device described above, the peripheral wall may have a frustum of a cone cylindrical shape, each heat transfer sheet may have a hexagonal shape, and may be attached to the outer surface so as to arrange one side in the circumferential direction of the outer surface.

[0010] According to the beverage container holding device described above, the heat conductor can be arranged so as to surround the peripheral wall with the height positions of the respective heat transfer sheets aligned in the frustum of a cone cylindrical-shaped peripheral wall. Thereby, even when the holder has a frustum of a cone cylindrical shape, a desired range in the beverage container can be suitably heated.

[0011] In the beverage container holding device, the heat transfer body includes a single heat transfer sheet having a strip shape wound along the circumferential direction of the outer surface of the peripheral wall, and the heat transfer sheet may include a plurality of slits extending from one side extending in the circumferential direction in a direction intersecting the circumferential direction and arranged at intervals along the circumferential direction.

[0012] According to the beverage container holding device, the slits provided in the heat transfer sheet enable the attachment of the peripheral wall with a single heat transfer sheet, for example, when the peripheral wall has a frustum-shaped cylindrical surface extending in the axial direction, by gradually widening the width of the slits in the circumferential direction along the axial direction. Further, for example, when the holder includes a bottom wall, the portion of the heat transfer sheet having slits can be made to protrude from the peripheral wall toward the bottom wall, and the protruding portion can be bent so as to attach the portion protruding to the bottom surface of the bottom wall. Thus, with a heat transfer sheet provided with slits, the heat transfer sheet can be easily attached following the structure of the holder.

[0013] In the beverage container holding device, the holder includes a bottom wall that supports the beverage container, and the bottom surface of the bottom wall may be in contact with the heat transfer body. According to this beverage container holding device, since the beverage container continues to be in contact with the bottom wall serving as a heat source due to its own weight, the beverage container can be suitably heated.

[0014] In the beverage container holding device, it further includes a circuit board that supplies current to the planar heating element, and the planar heating element includes a planar wiring including a resistance heating wire routed in a planar shape, one end connected to the resistance heating wire, and an external connection terminal that is the other end connected to the circuit board. The circuit board includes a fitting hole into which the external connection terminal of the planar wiring is inserted, and the external connection terminal may be soldered in a state of being inserted into the fitting hole. According to this beverage container holding device, since no other member is required between the planar heating element and the circuit board, it is possible to reduce the cost related to the manufacture of the beverage container holding device.

[0015] In the beverage container holding device, an operation switch that houses the circuit board and switches the supply and cutoff of current to the circuit board may be further provided, and the holder may be equipped with the operation switch. According to this beverage container holding device, since the holder is equipped with the operation switch, it is not necessary to separately prepare a structure for mounting the operation switch with respect to the mounting target of the beverage container holding device.

Effects of the Invention

[0016] According to the present invention, uniform heating over a wide range of the beverage container can be achieved, and excessive temperature rise in a local range occupied by the planar heating element can be suppressed.

Mode for Carrying Out the Invention

[0018] [First Embodiment] Referring to FIGS. 1 to 6, a first embodiment of the beverage container holding device will be described. FIG. 1 shows a state before the beverage container holding device is assembled.

[0019] The beverage container holding device (hereinafter also referred to as the holding device) 10 shown in FIG. 1 is configured to heat a beverage container. The beverage container may be, for example, a metal beverage can, a paper beverage cup, or a resin beverage bottle. The holding device 10 includes a holder 11, a heat conductor 12, a planar heating element 13, and a heat insulator 14. The holder 11 holds the beverage container inside the holder 11. The holder 11 is made of resin.

[0020] The heat conductor 12 is located outside the holder 11. The heat conductor 12 has a sheet shape. The thermal conductivity of the heat conductor 12 is higher than that of the holder 11. The planar heating element 13 is located outside the heat conductor 12. The planar heating element 13 is smaller than the heat conductor 12. That is, the planar heating element 13 covers at least a part of the heat conductor 12. The heat insulator 14 covers the planar heating element 13 outside the planar heating element 13.

[0021] According to the holding device 10 of the present disclosure, the heat of the planar heating element 13 is transmitted to the beverage container through the heat transfer body 12 larger than the planar heating element 13 and the resin holder 11. At this time, since the heat transfer body 12 diffuses the heat of the planar heating element 13 and the resin holder 11 diffuses the heat of the heat transfer body 12, the heat of the planar heating element 13 is transmitted to the beverage container over a wide range through the diffusion of the heat transfer body 12 and the holder 11. Further, the resin holder 11 suppresses directly transmitting the heat of the beverage container to the heat transfer body 12 and diffuses the heat of the beverage container within the resin holder. Such heat diffusion by the resin holder 11 suppresses the non-uniformity of the temperature distribution in the heat transfer body 12, thereby preferably promoting the diffusion of the heat of the planar heating element 13 described above. As a result, the heat insulation of the heat insulator 14 and the diffusion of the heat of the planar heating element 13 are combined to achieve uniform heating over a wide range of the beverage container, and excessive temperature rise in the local range occupied by the planar heating element 13 is suppressed.

[0022] The holder 11 is a resin molded product. The resin for forming the holder 11 may be various synthetic resins. The holder 11 includes a cylindrical portion 11A and a flange portion 11B. The cylindrical portion 11A includes a bottom wall that closes one end of the two ends in the axial direction of the cylindrical portion 11A. The cylindrical portion 11A defines an accommodation space 11AS by the inner surface of the cylindrical portion 11A. The accommodation space 11AS has a size capable of accommodating various beverage containers. As described above, the beverage container may be, for example, a beverage can, a beverage cup, and a beverage bottle. Note that the holder 11 may be formed in a shape capable of accommodating only a specific beverage container. In the present embodiment, the cylindrical portion 11A has a cylindrical shape, but the cylindrical portion 11A may have a frustum-shaped cylindrical shape or a rectangular cylindrical shape.

[0023] The flange portion 11B protrudes outward in the radial direction of the cylindrical portion 11A from the open end among the two ends of the cylindrical portion 11A. The flange portion 11B has a through-hole 11BH that penetrates the flange portion 11B along the thickness direction. The flange portion 11B includes a holding portion 11B1 and a locking portion 11B2. The flange portion 11B includes one holding portion 11B1 and the same number of locking portions 11B2 as the clip 16 described later.

[0024] The flange portion 11B has a pair of opposing surfaces in the flange portion 11B. One of the pair of surfaces is the upper surface, and the other is the lower surface. The holding portion 11B1 protrudes downward from the lower surface of the flange portion 11B. When viewed from a perspective facing the lower surface, the holding portion 11B1 has a shape that surrounds the through-hole 11BH. Each locking portion 11B2 protrudes downward from the lower surface of the flange portion 11B in the same manner as the holding portion 11B1.

[0025] The heat transfer body 12 includes a plurality of heat transfer sheets 12A. Each heat transfer sheet 12A may be formed from various metals. The heat transfer sheet 12A is formed from, for example, aluminum. The heat transfer body 12 of the present embodiment includes three heat transfer sheets 12A. Each heat transfer sheet 12A has a rectangular shape. The heat transfer sheet 12A has a shape that curves along the outer surface of the cylindrical portion 11A. As described above, since the cylindrical portion 11A has a cylindrical shape, in a cross-section orthogonal to the axial direction of the cylindrical portion 11A, each heat transfer sheet 12A has an arc shape such that the center of curvature is located inside the cylindrical portion 11A.

[0026] In the axial direction of the cylindrical portion 11A, the width of the heat transfer sheet 12A is smaller than the width of the cylindrical portion 11A. The heat transfer body 12 has a size, that is, a shape and area, that can cover substantially the entire lower half of the cylindrical portion 11A. Note that the lower half of the cylindrical portion 11A is a portion located below the holding portion 11B1 and the locking portion 11B2 in the axial direction of the cylindrical portion 11A.

[0027] Before being formed to follow the outer shape of the cylindrical portion 11A, the planar heating element 13 has a strip shape. When mounted on the holding device 10, the planar heating element 13 includes an annular portion 13A and a bent portion 13B. The annular portion 13A has an annular shape corresponding to the outer shape of the cylindrical portion 11A. The annular portion 13A has a shape that can sandwich the heat transfer sheet 12A between it and the cylindrical portion 11A.

[0028] The bent portion 13B is connected to one end of the annular portion 13A. The bent portion 13B includes one or more bent portions. The bent portion 13B is shaped such that it can be connected to an operation switch 15 described later and the operation switch 15 can be mounted on the flange portion 11B.

[0029] The planar heating element 13 includes a resistance heating wire 13C and a planar wiring (see FIG. 6). The resistance heating wire 13C is routed in a planar manner in the annular portion 13A. The planar wiring is connected to the resistance heating wire 13C and a circuit board (see FIG. 6) described later, thereby supplying current to the resistance heating wire 13C. Therefore, the planar heating element 13 can generate heat in a planar manner over the entire annular portion 13A. On the other hand, only the planar wiring is located in the bent portion 13B. The planar heating element 13 includes a covering portion 13D having insulation. The covering portion 13D covers the resistance heating wire 13C and the planar wiring.

[0030] In the axial direction of the cylindrical portion 11A, the width of the planar heating element 13, that is, the width of the annular portion 13A, is smaller than the width of the heat transfer body 12, that is, the heat transfer sheet 12A. Therefore, the size of the planar heating element 13, that is, the annular portion 13A, in other words, the shape and area, is smaller than the size of the heat transfer body 12. As a result, the annular portion 13A is located within the heat transfer body 12 when the holding device 10 is assembled.

[0031] The operation switch 15 is a mechanism for supplying current to the planar heating element 13. The operation switch 15 includes an operation button 15A, a case 15B, a packing 15C, and a fixing member 15D. The operation button 15A is configured to be able to control the start and stop of energization of the planar heating element 13. The case 15B houses a circuit board described later. The circuit board is connected to the operation button 15A and the planar heating element 13. The packing 15C is positioned between the operation button 15A and the flange portion 11B when the operation switch 15 is mounted on the holder 11, thereby suppressing the permeation of liquid from the flange portion 11B toward the operation switch 15. The fixing member 15D fixes the case 15B to the flange portion 11B.

[0032] The heat insulator 14 is made of resin. The heat insulator 14 has a cylindrical shape along the outer surface of the cylindrical portion 11A. In the heat insulator 14, a pair of end portions are open in the axial direction of the cylindrical portion 11A. In the axial direction of the cylindrical portion 11A, the width of the heat insulator 14 is larger than the width of the heat transfer sheet 12A and the width of the annular portion 13A. The heat insulator 14 has a size, that is, a shape and an area, capable of covering the lower half of the cylindrical portion 11A.

[0033] In the present embodiment, the heat insulator 14 has a pair of end portions in the circumferential direction of the heat insulator 14. The heat insulator 14 has elasticity capable of separating one end portion from the other end portion in the circumferential direction of the heat insulator 14. The heat insulator 14 may be formed of, for example, foamed rubber or resin. Therefore, it is easy to assemble the heat insulator 14 to the cylindrical portion 11A with the heat transfer body 12 and the planar heating element 13 sandwiched between the heat insulator 14 and the cylindrical portion 11A.

[0034] The holding device 10 includes a plurality of clips 16. The clips 16 are resin-molded products. In the present embodiment, the holding device 10 includes four clips 16, but the holding device 10 may include three or fewer clips 16 or five or more clips 16. Each clip 16 is locked to a different locking portion 11B2. The clip 16 has a shape extending along the axial direction of the cylindrical portion 11A. The clip 16 enables the holding device 10 to be fixed to an object to which the holding device 10 is attached. The object to which the holding device 10 is attached is, for example, a vehicle.

[0035] Figure 2 shows the state in which the holding device 10 is assembled. As shown in Figure 2, in the state where the holding device 10 is assembled, the heat insulator 14 covers the lower half of the cylindrical portion 11A so as to sandwich the heat transfer sheet 12A and the annular portion 13A between the heat insulator 14 and the cylindrical portion 11A. The clip 16 locked to the locking portion 11B2 and the case 15B held by the holding portion 11B1 are located outside the heat insulator 14 in the radial direction of the cylindrical portion 11A and above the heat insulator 14 in the axial direction of the cylindrical portion 11A. The bent portion 13B of the planar heating element 13 is exposed from the heat insulator 14.

[0036] The operation switch 15 is held by the holding portion 11B1 such that the top surface of the operation button 15A is exposed from the through hole 11BH when viewed from a perspective facing the upper surface of the flange portion 11B. Thereby, the holder 11 mounts the operation switch 15. Thus, since the holder 11 mounts the operation switch 15, it is not necessary to separately prepare a structure for mounting the operation switch 15 with respect to the object to which the holding device 10 is attached. Also, the user of the holding device 10 can press the operation button 15A within the through hole 11BH of the flange portion 11B.

[0037] Figure 3 shows the cross-sectional structure of the holding device 10. As shown in FIG. 3 and as described above, the holder 11 includes a cylindrical portion 11A. The cylindrical portion 11A includes a peripheral wall 11A1 and a bottom wall 11A2. The peripheral wall 11A1 has a cylindrical shape surrounding the beverage container. The bottom wall 11A2 supports the beverage container within the holder 11. The heat insulator 14 has a cylindrical shape and covers the lower half of the peripheral wall 11A1.

[0038] FIG. 4 shows an enlarged view of the structure included in the region A shown in FIG. 3. As shown in FIG. 4, the outer surface of the peripheral wall 11A1 is in contact with the heat transfer sheet 12A provided in the heat transfer body 12. Thereby, since the beverage container is heated by the holding device 10 so as to surround the beverage container, it is possible to suitably heat the entire beverage container.

[0039] The outer surface of the heat transfer sheet 12A is in contact with the annular portion 13A of the planar heating element 13. Thereby, it is possible to transfer the heat generated by the planar heating element 13 to the heat transfer body 12 with higher efficiency as compared with the case where a gap is located between the heat transfer sheet 12A and the annular portion 13A.

[0040] The inner surface of the heat insulator 14 preferably has a rigidity that allows deformation along the outer surface of the heat transfer sheet 12A and the outer surface of the annular portion 13A. As described above, for example, the heat insulator 14 can be formed of a foamed rubber or resin, so that the inner surface of the heat insulator 14 has a rigidity that allows deformation along the outer surface of the heat transfer sheet 12A and the outer surface of the annular portion 13A. Thereby, since no gap is formed between the heat insulator 14 and the heat transfer sheet 12A, heat transferred to the heat transfer body 12 is further suppressed from being released to the outside.

[0041] With reference to FIGS. 5 and 6, the structure of the operation switch 15 will be described in more detail. FIG. 5 shows the structure of the operation switch 15 viewed from the side. FIG. 6 shows a cross-sectional structure of the operation switch 15 along the vertical direction.

[0042] As shown in FIG. 5 and as described above, the operation switch 15 includes an operation button 15A and a case 15B. Of the bent portions 13B provided in the planar heating element 13, the end opposite to the end connected to the annular portion 13A is located inside the case 15B.

[0043] As shown in FIG. 6, the case 15B of the operation switch 15 houses a circuit board 15E. The case 15B includes an upper case 15B1 and a lower case 15B2. The operation button 15A is located on the upper case 15B1. The circuit board 15E is located above the lower case 15B2 and is covered by the upper case 15B1. The operation switch 15 switches the supply and cut-off of current to the circuit board 15E. The operation switch 15 is configured to switch the supply and cut-off of current to the circuit board 15E when the operation button 15A is pressed.

[0044] The circuit board 15E supplies current to the planar heating element 13. As described above, the planar heating element 13 includes a resistance heating wire 13C (see FIG. 1) and a planar wiring 13E. The planar wiring 13E includes one end connected to the resistance heating wire 13C and an external connection terminal 13E1 which is the other end connected to the circuit board 15E. Note that, of the planar wiring 13E, the external connection terminal 13E1 is exposed from the covering portion 13D.

[0045] The circuit board 15E has a fitting hole 15EH into which the external connection terminal 13E1 of the planar wiring 13E is fitted. The fitting hole 15EH penetrates the circuit board 15E in the thickness direction of the circuit board 15E. The circuit board 15E has two fitting holes 15EH. The external connection terminal 13E1 is soldered in a state of being fitted into the fitting hole 15EH. That is, solder 15E1 is located around the fitting hole 15EH in the circuit board 15E. The solder 15E1 covers the portion of the external connection terminal 13E1 fitted into the fitting hole 15EH and the fitting hole 15EH.

[0046] According to such a structure, since no other member is required between the planar heating element 13 and the circuit board 15E, it is possible to reduce the cost related to the manufacture of the holding device 10. Note that the other members are, for example, a cord and a connector.

[0047] As described above, according to the first embodiment of the beverage container holding device, the following effects can be obtained. (1-1) Uniform heating over a wide range of the beverage container can be achieved, and excessive temperature rise in the local range occupied by the planar heating element 13 can be suppressed.

[0048] (1-2) Since the beverage container is heated by the holding device 10 so as to surround the beverage container, it is possible to suitably heat the entire beverage container.

[0049] (1-3) Since no other member is required between the planar heating element 13 and the circuit board 15E, it is possible to reduce the cost related to the manufacture of the holding device 10.

[0050] (1-4) Since the holder 11 is equipped with the operation switch 15, it is not necessary to separately prepare a structure for mounting the operation switch 15 with respect to the mounting object of the holding device 10 other than the holding device 10.

[0051] (1-5) Since the area of each heat transfer sheet 12A is smaller than the case where the heat transfer body 12 includes a single heat transfer sheet, the handling of the heat transfer sheet 12A is easy.

[0052] Note that the above-described embodiment can be implemented with the following modifications. [Operation switch] · The operation switch 15 does not have to be mounted on the holder 11. In this case, the operation switch 15 may be mounted, for example, as a part of the mounting object of the holding device 10 and at a position away from the holder 11.

[0053] [Planar heating element] ·The external connection terminal 13E1 provided in the planar heating element 13 may not be soldered to the circuit board 15E. In this case, for example, wiring for connecting the external connection terminal 13E1 to the circuit board 15E may be located between the external connection terminal 13E1 of the planar heating element 13 and the circuit board 15E.

[0054] [Heat transfer body] ·The heat transfer body 12 may include a heat transfer sheet, which will be described below with reference to FIGS. 7 and 8.

[0055] As shown in FIG. 7, each heat transfer sheet 22A has a hexagonal shape. The heat transfer sheet 22A has a hexagonal shape in which two corners arranged along the longitudinal direction in a rectangle are cut off. In the longitudinal direction, the heat transfer sheet 22A has a pair of end portions 22A1.

[0056] As shown in FIG. 8, the peripheral wall 21A1 has a frustum of a cone cylindrical shape. The heat transfer sheet 22A included in the heat transfer body 12 is attached to the outer surface of the peripheral wall 21A1. Each heat transfer sheet 22A is attached to the outer surface so that one side is arranged in the circumferential direction of the outer surface. The end portion 22A1 of each heat transfer sheet 22A overlaps the end portion of the adjacent heat transfer sheet 22A.

[0057] According to the heat transfer body 12 described above, the effects described below can be obtained. (1-6) In the frustum of a cone cylindrical-shaped peripheral wall 21A1, the heat transfer body can be arranged so that the height positions of the heat transfer sheets 22A are aligned to surround the peripheral wall 21A1. Thereby, even when the holder 11 has a frustum of a cone cylindrical shape, a desired range in the beverage container can be suitably heated.

[0058] Note that the heat transfer sheet 22A having a hexagonal shape has the following advantages over the heat transfer sheet 22A having a rectangular shape. That is, when wrapping a heat transfer sheet having a rectangular shape along the outer surface of the peripheral wall 21A1 having a truncated conical cylindrical shape, in the axial direction of the peripheral wall 21A1, the end portion in the longitudinal direction of the heat transfer sheet is located above the central portion in the longitudinal direction of the heat transfer sheet. Therefore, when the width of the heat transfer sheet is increased at the central portion in the longitudinal direction, the end portion in the longitudinal direction may exceed the covering region that the heat transfer sheet should cover in the axial direction of the peripheral wall 21A1. Thus, when maintaining the shape of the heat transfer sheet as a rectangular shape, it is necessary to narrow the width of the heat transfer sheet, thereby avoiding the end portion in the longitudinal direction from exceeding the covering region.

[0059] In this regard, according to the heat transfer sheet 22A having a hexagonal shape, since the corner portions at the end portions in the longitudinal direction are cut off, it is possible to expand the width of the heat transfer sheet 22A such that the end portions in the longitudinal direction exceed the covering region. In other words, compared with the heat transfer sheet having a rectangular shape, even if the width of the heat transfer sheet 22A is increased, it is possible to suppress the end portions in the longitudinal direction from exceeding the covering region. As a result, it is possible to expand the range in which the heat transfer body 12 transfers the heat of the planar heating element 13.

[0060] · The heat transfer body 12 may include only one or two heat transfer sheets 12A, or may include four or more heat transfer sheets 12A. When the heat transfer body 12 includes two or more heat transfer sheets 12A, the heat transfer sheets 12A may be mounted on the holding device 10 so that two or more heat transfer sheets 12A are arranged in the axial direction of the cylindrical portion 11A.

[0061] · The heat transfer body 12 may be located outside the bottom wall 11A2 while not being located outside the peripheral wall 11A1 among the outside of the holder 11. In this case, the planar heating element 13 and the heat insulating body 14 may also be located only outside the bottom wall 11A2. Even in this case, the effects according to (1-1) described above can be obtained.

[0062] [Second Embodiment] Referring to FIG. 9, a second embodiment of the beverage container holding device will be described. In the second embodiment, the shape of the heat transfer sheet provided in the heat transfer body is different from that of the first embodiment described above. Therefore, hereinafter, while explaining such differences in detail, a detailed description of the components of the beverage holding device other than the heat transfer body will be omitted.

[0063] FIG. 9 shows a perspective structure of the heat transfer body. As shown in FIG. 9, the heat transfer body includes a single heat transfer sheet 32. The heat transfer sheet 32 has a strip shape wound along the circumferential direction of the outer surface of the peripheral wall 11A1. The heat transfer sheet 32 is provided with a plurality of slits 32S. Each slit 32S extends from one side extending along the circumferential direction of the outer surface in a direction intersecting the circumferential direction of the outer surface. The plurality of slits 32S are arranged at intervals along the circumferential direction of the outer surface.

[0064] In the example shown in FIG. 9, the heat transfer sheet 32 has a size that covers the lower half of the peripheral wall 11A1, similar to the heat transfer sheet 12A of the first embodiment. The heat transfer sheet 32 has a pair of sides facing each other in the axial direction of the peripheral wall 11A1. Of the pair of sides, one side is the upper side and the other side is the lower side. Each slit 32S extends from the lower side toward the upper side and along the axial direction of the peripheral wall 11A1. The plurality of slits 32S are arranged at equal intervals in the circumferential direction.

[0065] Therefore, when the heat transfer sheet 32 is wound around the outer surface of the peripheral wall 11A1, it is possible for the width of the slit 32S in the circumferential direction of the peripheral wall 11A1 to change compared to before winding. Also, when the heat transfer sheet 32 is wound around the outer surface of the peripheral wall 11A1, the portion sandwiched between adjacent slits 32S can be deformed. Thereby, in the case of the heat transfer sheet 32 provided with the slits 32S, the heat transfer sheet 32 can be easily attached following the structure of the holder 11.

[0066] In each slit 32S, the end located at the lower side is the base end, and the end located between the lower side and the upper side is the tip end. The heat transfer sheet 32 has a through hole 32H continuous with the tip end of each slit 32S. The through hole 32H penetrates the heat transfer sheet 32 along the thickness direction of the heat transfer sheet 32. When viewed from a perspective facing the outer surface of the heat transfer sheet 32, the outer shape of the through hole 32H is circular.

[0067] Thus, the heat transfer sheet 32 has a through hole 32H continuous with the tip end of the slit 32S. Therefore, when a portion of the heat transfer sheet 32 sandwiched between adjacent slits 32S is displaced in the circumferential direction of the peripheral wall 11A1 or bent along the radial direction of the peripheral wall 11A1, breakage of the heat transfer sheet 32 at the tip end of the slit 32S can be suppressed.

[0068] As described above, according to the second embodiment of the beverage container holding device, in addition to the effects (1-1) to (1-4) described above, the following effects can be obtained. (2-1) The heat transfer sheet 32 is easily attached following the structure of the holder 11.

[0069] Note that the second embodiment can be implemented with the following modifications. [Heat transfer sheet] · The heat transfer sheet 32 may not have the through hole 32H. Even in this case, by providing the heat transfer sheet 32 with a plurality of slits 32S, the effects similar to those in (2-1) described above can be obtained.

[0070] · The direction in which each slit 32S extends is not limited to the axial direction of the peripheral wall 11A1, and may be a direction from the lower side toward the upper side and intersecting the axial direction. Even in this case, the effects similar to those in (2-1) described above can be obtained.

[0071] · The slit 32S may extend from the upper side to the lower side of the heat transfer sheet 32. That is, the base end of the slit 32S may be located on the upper side, and the tip end may be located between the upper side and the lower side. In this case, the following effects can be obtained.

[0072] (2-2) When the peripheral wall 11A1 has a frustum-shaped cylindrical surface extending in the axial direction, for example, the width of the slit 32S in the circumferential direction of the peripheral wall 11A1 can gradually increase along the direction from the lower side to the upper side of the heat transfer sheet 32. Thereby, it is easy to attach one heat transfer sheet 32 along the outer surface of the peripheral wall 11A1.

[0073] · The width of the heat transfer sheet 32 may be larger than the width of the lower half of the peripheral wall 11A1. In this case, it is preferable that the tip end of the slit 32S is located above the bottom wall 11A2. Thereby, the following effects can be obtained.

[0074] (2-3) It is possible to bend the protruding portion so that the portion of the heat transfer sheet 32 having the slit 32S protrudes from the peripheral wall 11A1 toward the bottom wall 11A2 and the protruding portion on the bottom surface of the bottom wall 11A2 is attached to the bottom surface. According to such a heat transfer sheet 32, it is also possible to transfer the heat generated by the planar heating element 13 along the bottom wall 11A2.

[0075] In addition, when the peripheral wall 11A1 has a frustum-shaped cylindrical surface extending in the axial direction and the slits 32S are arranged at equal intervals, in the portion of the heat transfer sheet 32 that covers the lower part of the peripheral wall 11A1 and the portion that covers the bottom wall 11A2, a part of the heat transfer sheet 32 overlaps with other parts. Moreover, such an overlap becomes larger in the portion of the heat transfer sheet 32 that covers the bottom wall 11A2, and thereby, the volume of the heat transfer sheet 32 per unit area becomes larger. Therefore, even if the planar heating element 13 is only located on the peripheral wall 11A1, the heat generated by the planar heating element 13 is likely to be transferred to the bottom wall 11A2. As a result, the entire holder 11 is likely to warm up.

[0076] [Other modification examples] · The beverage holding device of the second embodiment may be implemented in combination with the modification examples related to the operation switch 15 and the modification examples related to the planar heating element 13 among the modification examples of the first embodiment described above.

[0077] [Third Embodiment] Referring to FIGS. 10 and 11, a third embodiment of the beverage container holding device will be described. In the third embodiment, compared with the first embodiment described above, the shape of the heat transfer sheet included in the heat transfer body and the structure of the heat insulating body are different. Therefore, in the following, while explaining such differences in detail, detailed explanations of the beverage holding device other than the heat transfer body and the heat insulating body will be omitted.

[0078] FIG. 10 shows a perspective structure of the heat transfer body. As shown in FIG. 10, the heat transfer body 42 includes a peripheral wall sheet 42A and a bottom wall sheet 42B. The peripheral wall sheet 42A has a cylindrical shape along the outer surface of the peripheral wall 11A1. The peripheral wall sheet 42A is a single sheet having a belt shape and is formed along the outer surface of the peripheral wall 11A1.

[0079] The bottom wall sheet 42B includes a bottom wall portion 42B1 and a side wall portion 42B2. The bottom wall portion 42B1 has a circular shape along the bottom wall 11A2. The side wall portion 42B2 has an annular shape rising from the edge of the bottom wall portion 42B1. The side wall portion 42B2 is provided with a plurality of slits 42BS. Each slit 42BS has a tip at the edge of the bottom wall portion 42B1 and penetrates the side wall portion 42B2 along the axial direction of the peripheral wall 11A1. The plurality of slits 42BS are arranged at equal intervals in the circumferential direction of the peripheral wall 11A1.

[0080] A plurality of through holes 42BH are located at the edge of the bottom wall portion 42B1. Each through hole 42BH penetrates the bottom wall portion 42B1 along the thickness direction of the bottom wall portion 42B1. The plurality of through holes 42BH are arranged at equal intervals along the circumferential direction of the peripheral wall 11A1. Each through hole 42BH is connected to a different slit 42BS. Thereby, when the side wall portion 42B2 is bent, it is possible to prevent the bottom wall sheet 42B from being torn at the tip of the slit 42BS.

[0081] In a state where the heat transfer body 42 is assembled to the holding device 10, the side wall portion 42B2 of the bottom wall sheet 42B covers the lower end of the peripheral wall sheet 42A. Thereby, the heat generated by the planar heating element 13 is transmitted to the bottom wall sheet 42B through the peripheral wall sheet 42A. Further, in a state where the heat transfer body 42 is assembled to the holding device 10, the bottom wall portion 42B1 of the bottom wall sheet 42B is in contact with the bottom surface of the bottom wall 11A2. Thereby, since the beverage container continues to be in contact with the bottom wall 11A2, which is a heat source, due to the weight of the beverage container, the beverage container can be suitably heated.

[0082] FIG. 11 shows a perspective structure of the heat insulating body. As shown in FIG. 11, the heat insulating body 44 includes a peripheral wall portion 44A and a bottom wall portion 44B. The peripheral wall portion 44A has a cylindrical shape along the outer surface of the peripheral wall 11A1. The bottom wall portion 44B has a disk shape along the bottom wall 11A2. In a state where the heat insulating body 44 is assembled to the holding device 10, the peripheral wall portion 44A covers the outer surface of the peripheral wall sheet 42A, and the bottom wall portion 44B covers the bottom surface of the bottom wall sheet 42B.

[0083] As described above, according to the third embodiment of the beverage container holding device, in addition to the effects (1-1) to (1-4) described above, the following effects can be obtained. (3-1) Since the beverage container continues to be in contact with the heat source due to the weight of the beverage container, the beverage container can be suitably heated.

[0084] Note that the third embodiment can be implemented with the following modifications. [Heat transfer sheet] · The bottom wall sheet 42B may not have the through hole 42BH. Even in this case, by providing the heat transfer body 42 with the bottom wall sheet 42B, the effect according to the above-described (3-1) can be obtained.

[0085] · The bottom wall sheet 42B may not have the slit 42BS. Even in this case, for example, when raising the side wall portion 42B2 from the bottom wall portion 42B1, it is possible to form the bottom wall sheet 42B including the bottom wall portion 42B1 and the side wall portion 42B2 by forming a fold at the boundary between the bottom wall portion 42B1 and the side wall portion 42B2. Also, even in this case, by providing the heat transfer body 42 with the bottom wall sheet 42B, the effect according to the above-described (3-1) can be obtained.

[0086] [Planar heating element] · In addition to the outside of the peripheral wall sheet 42A, a planar heating element may also be located outside the bottom wall sheet 42B. In this case, the beverage container held by the holding device 10 is more likely to be further heated.

[0087] · The planar heating element may be located outside the bottom wall sheet 42B while not being located outside the peripheral wall sheet 42A. Even in this case, the heat generated by the planar heating element is also transmitted to the peripheral wall sheet 42A through the bottom wall sheet 42B, so that the entire beverage container is likely to be heated.

[0088] [Other modification examples] · The beverage holding device of the third embodiment may be implemented in combination with the modification examples related to the operation switch 15 and the modification examples related to the planar heating element 13 among the modification examples of the first embodiment described above. Also, the heat insulator 44 included in the beverage holding device of the third embodiment may be combined with the beverage holding device of the first embodiment.

[0089] · The beverage holding device of the third embodiment may be implemented in combination with the beverage holding device of the second embodiment described above. That is, in the beverage holding device of the second embodiment, in addition to the heat transfer sheet 32 described above, the heat transfer body may further include the bottom wall sheet 42B included in the heat transfer body 42 of the third embodiment. Further, the beverage holding device of the second embodiment may include the heat insulator 44 included in the beverage holding device of the third embodiment.

[0090] [General problems] The beverage container holding device of the present disclosure contributes to solving the general problem of enhancing the comfort in the vehicle interior when the beverage container holding device is applied to a vehicle. In particular, the beverage holding device contributes to solving the problem of enhancing the convenience of the beverage container holding device.
