<Cork with light>
The cork with a light according to the present invention is a cork 1 with a light that is attached to an opening of an empty wine bottle and illuminates the inside of the bottle with light. As shown in FIGS. 1, 2, and 3, An electrically conductive hollow cylindrical portion 12 provided inside and having an inner peripheral radius 12a larger than the outer peripheral radius 11a of the battery 11 by a predetermined gap, a thickness 13a thinner than the gap, and an outer peripheral side surface of the battery 11 An electrically insulating holding part 13 attached to the battery and a battery 11 housed in the hollow cylindrical part 12 with the holding part 13 attached.

  Further, the cork 1 with light according to the present invention is provided at the lower end of the hollow cylindrical portion 12, and one electric wire 14a is electrically connected to the lower electrode 11b of the battery 11 accommodated therein, and the other electric wire. 14 b is provided at the light source portion 14 electrically connected to the inner peripheral side surface (inner wall) of the hollow cylindrical portion 12 and the upper end portion of the hollow cylindrical portion 12, and one conductive wire 15 a is provided inside the hollow cylindrical portion 12. It is electrically connected to the peripheral side surface, and the other conducting wire 15b is provided with the connection part 15 electrically connected to the electrode 11c above the accommodated battery 11, It is characterized by the above-mentioned.

  Thereby, the whole hollow cylindrical part 12 is made to function as wiring, and it becomes possible to reduce the number of wiring and to make it a simple structure. For this reason, complicated wiring soldering or the like is unnecessary, and the cost can be reduced.

  Further, since the inner peripheral radius 12a of the hollow cylindrical portion 12 is slightly larger than the outer peripheral radius 11a of the battery 11, a useless space for storing the battery 11 is eliminated, and a light emitting unit (for emitting light) ( Battery 11, light source unit 14, connection unit 15, etc.) can be reduced in size. Therefore, the above-described light emitting unit can be accommodated in the cork main body 10 in a compact manner.

  Here, when the hollow cylindrical portion 12 is caused to function as a wiring, there is a concern that an electric circuit may be short-circuited due to electrical contact between the battery 11 housed therein and the hollow cylindrical portion 12. However, in the present invention, since the electrically insulating holding portion 13 is provided between the battery 11 and the hollow cylindrical portion 12, it is possible to reliably prevent the occurrence of the short circuit described above. In addition, by attaching the holding portion 13 to the outer peripheral side surface of the battery 11, when the battery 11 is taken in and out of the hollow cylindrical portion 12, the electrical contact with the hollow cylindrical portion 12 is surely prevented, Increase user safety.

  Furthermore, by providing the hollow cylindrical portion 12 inside the cork body 10, the cork body 10 functions as an electrically insulating protective layer. Therefore, even if the hollow cylindrical portion 12 is used as a wiring, the user does not get an electric shock by touching the cork main body 10 and is safe.

  Further, since all the above-described light emitting units are built in the cork body 10, as shown in FIG. 4, it is possible to make the user feel as if the cork stopper is shining, which gives the user surprise and interest. Is possible.

  And if the cork 1 with a light which concerns on this invention is attached to the opening part of an empty wine bottle and light-emits inside, as shown in FIG. 5, the whole wine bottle will illuminate fantastically and the whole wine bottle will be used as a lighting fixture. It can be used. Here, since all the light emitting units described above are built in the cork main body 10, it is possible to put various kinds of decorations inside the wine bottle. Therefore, as shown in FIG. 5, the user creates a lighting device having an appearance according to the decorations that have been put in by putting decorations such as flowers, jewels, ores, and water into the interior of the wine bottle. Is possible. In other words, the user can easily make his / her favorite lighting fixture.

  Here, the gap is not particularly limited as long as the object of the present invention is not impaired. For example, the gap is preferably in the range of 0.1 mm to 1.0 mm. If comprised in this way, the thickness of the said holding | maintenance part 13 is designed in the range of 0.05-0.50 mm, for example, and a user attaches the battery 11 with which the said holding | maintenance part 13 was mounted | worn to the said hollow cylindrical part 12 It becomes possible to take in and out without difficulty.

  Further, the length of the hollow cylindrical portion 12 in the longitudinal direction is not particularly limited as long as the object of the present invention is not impaired. For example, as shown in FIG. 1, the length of the hollow cylindrical portion 12 in the longitudinal direction is longer than the length of the battery 11 in the longitudinal direction and corresponds to the length of the cork main body 10 in the longitudinal direction. If comprised in this way, the through-hole whose inner periphery radius is equivalent to the outer periphery radius of the said hollow cylinder part 12 will be opened along the longitudinal direction in the center of the cork main body 10, and the hollow cylinder part 12 mentioned above may be inserted into the through-hole. Since it only has to be attached, assembly is simplified.

  The shape of the hollow cylindrical portion 12 is not particularly limited as long as the object of the present invention is not impaired. For example, as shown in FIGS. 1, 2, and 3, the hollow cylindrical portion 12 preferably has a cylindrical shape corresponding to the shape of the battery 11.

  Further, the thickness (wall thickness) of the outer periphery of the hollow cylindrical portion 12 is not particularly limited as long as the object of the present invention is not impaired. For example, the thickness is preferably in the range of 0.1 mm to 1.0 mm. If comprised in this way, manufacture will become easy and the said hollow cylindrical part 12 can be further reduced in size.

  The material of the hollow cylindrical portion 12 is not particularly limited as long as the object of the present invention is not impaired. For example, examples of the material of the hollow cylindrical portion 12 include aluminum, stainless steel, copper, and conductive plastic.

  The shape of the holding portion 13 is not particularly limited as long as the object of the present invention is not impaired. For example, as shown in FIG. 6, the thickness 13 a is thinner than the gap, the longitudinal length 13 b corresponds to the longitudinal length 11 d of the battery 11, and the inner diameter 13 c is equal to the outer peripheral radius 11 a of the battery 11. An annular shape that has a certain electrically insulating cylindrical shape and that allows only the convex electrode 11b to be exposed at the lower end facing the convex electrode (here, the lower electrode 11b) of the battery 11 housed inside. The flange 13d is provided. If comprised in this way, since the length 13b of the holding part 13 in the longitudinal direction corresponds to the length 11d of the longitudinal direction of the battery 11, the lower electrode 11b and the upper electrode 11c of the battery 11 are reliably exposed. At the same time, it is possible to reliably prevent occurrence of a short circuit on the outer peripheral side surface of the battery 11. In addition, the presence of the flange 13d allows the user to insert the convex electrode 11b of the battery 11 corresponding to the flange 13d of the holding portion 13 in consideration of the storage direction of the electrode 11b of the battery 11. It becomes possible.

  Furthermore, when the battery 11 is a battery group in which a predetermined number (for example, three) of button batteries are arranged in series, the shape of the holding portion 13 is particularly preferable. If comprised in this way, it will become possible to handle a predetermined number of button batteries as one battery by the flange 13d of the holding | maintenance part 13, and a user can carry out the insertion / extraction of the said battery 11, and replacement | exchange easily, Furthermore, the above-mentioned The occurrence of short circuit can also be prevented.

  In the case of the holding portion 13 shown in FIG. 6, the inner peripheral radius 13e of the annular ring of the flange 13d is set to be equal to the outer peripheral radius 11e of the convex electrode 11b of the battery 11. The inner diameter 13c of the holding portion 13 being equal to the outer peripheral radius 11a of the battery 11 means that the inner diameter 13c of the holding portion 13 is the same as or slightly larger than the outer peripheral radius 11a of the battery 11.

  The holding portion 13 may have other shapes. For example, as shown in FIG. 7, the thickness 13a is thinner than the gap, and the longitudinal length 13b is the longitudinal length of the battery 11. An electrically insulating plate corresponding to the length 11d is curved along the outer peripheral side surface of the battery 11 so that the cross section in the longitudinal direction has a C shape having an inner peripheral radius 13c smaller than the outer peripheral radius 11a of the battery 11. . With this configuration, as described above, it is possible to reliably expose the lower electrode 11b and the upper electrode 11c of the battery 11 and to prevent occurrence of a short circuit on the outer peripheral side surface of the battery 11. Further, since the C-shaped inner peripheral radius 13 c of the holding portion 13 is smaller than the outer peripheral radius 11 a of the battery 11, the holding portion 13 firmly sandwiches the battery 11 and the battery 11 is detached from the holding portion 13. There is no safety. Further, the holding portion 13 is not formed in a cylindrical shape but is formed in a C shape so that both end portions 13f and 13g (the right end portion 13f and the left end portion 13g) of the holding portion 13 are opened as outer peripheral side surfaces of the battery 11. It becomes easy to attach to. Further, when the battery 11 is a battery group in which a predetermined number of button batteries are arranged in series, the holding unit 13 firmly holds the predetermined number of batteries 11 in the same manner as described above. Can be handled as a single battery.

  The distance (difference) between the C-shaped inner peripheral radius 13c of the holding portion 13 and the outer peripheral radius 11a of the battery 11 is not particularly limited as long as the object of the present invention is not impaired. For example, the interval is preferably in the range of 0.1 mm to 1.0 mm. If comprised in this way, it will become possible to attach the said holding | maintenance part 13 to the outer peripheral side surface of the battery 11 without difficulty.

  Moreover, the space | interval of the both ends 13f and 13g of the said holding | maintenance part 13 is not specifically limited unless the objective of this invention is inhibited. For example, the interval is preferably in the range of 0.1 mm to 1.0 mm. If comprised in this way, the electrical contact with the outer peripheral side surface of the said battery 11 and the inner peripheral side surface of the hollow cylindrical part 12 can be prevented reliably.

  Further, the material of the holding portion 13 is not particularly limited as long as the object of the present invention is not impaired. For example, a flexible member or an elastic member such as an electrically insulating plastic, resin, or rubber can be used. Thereby, since the shape of the holding portion 13 can be deformed by the user's handling, it is easy to attach the battery 11 to the outer peripheral side surface.

  The battery 12 is not particularly limited as long as the object of the present invention is not impaired. For example, the battery 12 is preferably a button battery that is thinner and lighter than a dry battery. Here, since one button battery has little power to the light source unit 14 and cannot be used for a long time, for example, as shown in FIGS. 1, 6, and 7, a predetermined number of button batteries are arranged in series. It is recommended to use the battery group as a single battery. In this case, the power to the light source unit 14 is sufficient, and it can be used for a long time.

  The light source unit 14 is not particularly limited as long as the object of the present invention is not impaired. For example, LED light sources such as white, red, green, and blue are adopted, but a light bulb may be used.

  Moreover, in this invention, as shown in FIG. 1, the switch part 16 which attaches / detaches electrically one conductor 15a of the said connection part 15 and the other conductor 15b further by a user's operation is further provided. Thereby, it becomes possible to control lighting and extinguishing of the light source unit 14 in accordance with a user operation.

  Here, the switch unit 16 is not particularly limited as long as the object of the present invention is not impaired. For example, a knock type switch unit 16 is employed. In the knock type switch unit 16, when the user presses the switch unit 16 downward once, the switch unit 16 electrically connects the one conductor 15a and the other conductor 15b, and the user again When the switch portion 16 is pressed downward, the switch portion 16 electrically disconnects one of the conductive wires 15a and the other conductive wire 15b.
