The bottom lid body 31 is installed on the bottom surface of the top lid body 20 and is disposed inside the second flange 23. The bottom lid body 31 is a disk-like body, and the shape is not limited to a square with a corner R as shown in FIG. 2, but may be another shape, for example, an elliptical shape. The holder 32 and the temperature control circuit 33 are installed between the bottom lid 31 and the top lid 20. The holder 32 holds the temperature control circuit 33, but the holder 32 may not be provided as long as the temperature control circuit 33 can be fixed between the bottom lid body 31 and the top lid body 20. The term “between the bottom cover body 31 and the upper cover body 20” does not exclude the provision of the temperature within the upper cover body 20, and a part of the temperature control circuit 33 may be provided in the upper cover body 20. For example, in the temperature control circuit 33, the light receiving portion of the photodiode 40 can be provided on the upper surface of the upper lid 20, and the connector 331 is provided so as to be exposed on the upper surface of the upper lid 20.

  As shown in FIG. 6, a plurality of convex plates 312 are provided at the outer end of the bottom cover body 31, and the second flange 23 is combined with a plurality of fitting holes 232 that are formed on the sides of the convex plates 312. Each convex plate 312 is fitted in each fitting hole 232. Thereby, the bottom lid 31 is fixed to the upper lid 20. The holder 32 is a disk-like body and has a temperature control circuit 33 therein.

  As shown in FIG. 7, the temperature control circuit 33 is based on a connector 331, a thermal element 332 serving as a temperature change element, a temperature detection element 333 that detects the temperature of the thermal element 332, and a temperature detected by the temperature detection element 333. A current control unit 334 that controls conduction and interruption of a current flowing through the thermal element 332 is provided. The temperature control circuit 33 further includes a MOS transistor 335 that switches between conduction and interruption of current, a photodiode 40 that serves as a light receiving element that detects ambient brightness, and a resistor 336 that is connected to the anode side of the photodiode 40.

The MOS transistor 335, the photodiode 40, and the resistor 336 are turned on and off according to the brightness of the surroundings, and become a switch portion that conducts and cuts off a current that flows through the thermal element 332. The switch unit may have another configuration as long as the switch operation is possible.

The connector 331, the MOS transistor 335, the current control unit 334, and the thermal element 332 are electrically connected to form a circuit loop. The connector 331 is fitted on the upper lid 20 and connected to an external power source (not shown). The connector 331 is a micro USB type connector, but another type of connector may be adopted as the connector 331 and is not limited to the micro USB type connector used in this embodiment.
The thermal element 332 is affixed to the bottom lid 31 and is used to change the temperature of the bottom lid 31 and heats the bottom lid 31. The heating element 332 can be a planar heating element such as a film heater or a rubber heater.

  According to the first embodiment described above, when the pedestal 10 is placed on the wet tissue, first, the user removes the seal piece attached to the outside of the take-out port of the wet tissue 50 to expose the take-out port. . Thereafter, the user peels off the release paper 16 at the bottom end of the base 10 to expose the adhesive surface 152. And a user sticks the base 10 on the upper part of a wet tissue using the film 15 so that the hole part 11 may oppose the taking-out port of the wet tissue 50. FIG. Thus, the user can take out the nonwoven fabric containing moisture in the wet tissue through the hole 11 and the take-out port of the wet tissue 50.

  When the upper end of the pedestal 10 is covered with the upper lid 20, the take-out port of the wet tissue 50 is blocked, and the drying speed of the non-removed nonwoven fabric in the wet tissue is reduced. When the upper end of the base 10 is covered with the upper lid 20 and the connector 331 is electrically connected to an external power source and light is detected by the photodiode 40, the MOS transistor 335 is turned on and the thermal element 332 is turned on. Is supplied with current. The thermal energy generated by heating the thermal element 332 is transferred to the inside of the wet tissue 50 through the bottom lid 31, and the nonwoven fabric is heated by the thermal energy, so that the comfort in using the wet tissue is increased. When the non-woven fabric in the wet tissue is lost, the base 10 is peeled off from the empty wet tissue and then the base 10 is attached to another wet tissue by the film 15. In this way, the wet tissue lid of this embodiment can be used repeatedly.

When the protrusion 343a of the open / close detection switch 343 is pushed in, the common terminal (COM) and the ON terminal of the open / close detection switch 343 are electrically connected. Then, current flows from the battery 338 shown in FIG. 10 to the thermal element 332 via the open / close detection switch 343 and the current control unit 334. When the opening / closing detection switch 343 is not pushed into the protruding portion 343a, the protruding portion 343a pops out, the conduction between the common terminal (COM) and the ON terminal of the opening / closing detection switch 343 is cut off, and a current flows through the thermal element 332.

(Fifth embodiment)
In the first to fourth embodiments, the user flips up the upper lid body 20 with respect to the base 10 by pulling up the protruding portion 26 of the upper lid body 20 in the upward direction. In this case, since it is necessary to disengage the engagement between the first hook portion 14 and the second hook portion 25 and the engagement between the vertical wall 12 and the fitting groove 24, the user pulls the protruding portion 26 upward. Is required.
In the present embodiment, a wet tissue lid is described in which the upper lid can be automatically flipped up with respect to the pedestal by depressing the operation unit. In the following description, the description of the portion corresponding to the temperature change unit 30 in FIG. 3 is omitted, but the portion corresponding to the temperature change unit 30 is attached to the bottom surface of the upper lid 60.

  FIG. 14 is a perspective view showing a state in which the wet tissue lid in the fifth embodiment is attached to the upper end of the wet tissue in a state where the upper lid is flipped up with respect to the base. FIG. 15 is a perspective view showing a state in which the wet tissue lid in the fifth embodiment is attached to the upper end of the wet tissue in a state where the base and the upper lid are combined. Needless to say, the temperature control circuit described in the first to fourth embodiments can also be applied to the fifth embodiment. In FIG. 15, the photodiode 40 shown in FIG. 1, the photodiode 40 and the external temperature detecting element 340 shown in FIG. 8B are omitted. Further, in FIG. 15, in order to attach the connector 331 to the upper surface of the upper lid 60, it is needless to say that the shape of the upper lid body 20 as shown in FIGS.

  In the state where the pedestal 70 and the upper lid 60 shown in FIG. 15 are combined, the user pushes down the operation unit 72 shown in FIG. Then, the hook portion 61 is disengaged from the operation portion 72, and the upper lid 60 rotates relative to the base 70 by the elastic force of the pair of rubber pieces 80-1 and 80-2, and the upper lid 60 jumps up. Then, the wet tissue take-out port is exposed, thereby making it possible to take out the non-woven fabric of wet tissue. Further, when closing the upper lid 60, the user rotates the upper lid 60 against the elastic force of the pair of rubber pieces 80-1 and 80-2. In FIG. 14, one flange 62 is provided instead of the first flange 22 and the second flange 23 of FIG. 2 and can be combined with the vertical wall 73 of the base 70.

One end of the pair of rubber pieces 80-1 and 80-2 is fixed by rubber piece pressers 71-1 and 71-2. The rubber piece pressers 71-1 and 71-2 are respectively formed with holes into which the ends of the pair of rubber pieces 80-1 and 80-2 enter. When the pedestal 70 and the upper lid 60 are combined, the rubber pieces 80-1 and 80-2 are bent, and when the operation unit 72 is pushed downward, the rubber pieces 80-1 and 80-2 return to their original positions. The upper lid 60 jumps up with respect to the pedestal 70 due to the elastic force to try.
Note that the rubber pieces do not necessarily have to be a pair, and as shown in FIG. 16, one rubber piece 80 may be used and one rubber piece presser 71 may be provided.

  In each of the first to fifth embodiments described above, the case where the thermal element is used as the temperature change element has been described. However, a cooling element such as a Peltier element may be used as the temperature change element. The cooling element cools the bottom lid and cools the nonwoven fabric in the wet tissue. This increases the comfort in using wet tissue in regions or seasons of extreme heat. The temperature detection element 333 is used for sensing the temperature of the cooling element, and the current control unit 334 cuts off the current when the temperature of the cooling element drops to a predetermined safe temperature, and stops the absorption of the thermal energy of the cooling element. Thereby, it is avoided that the temperature of a cooling element and a bottom cover body becomes low too much. After the current is cut off, when the temperature of the cooling element rises to a predetermined starting temperature, the current control unit 334 causes a current to flow, and the cooling element starts to absorb heat energy. As the temperature change element, both a heat element and a cooling element may be provided and switched to either the heat element or the cooling element according to the temperature detection value of the external temperature detection element 340 shown in FIG. 8A.
