  Below, each component with which the mug 1 with a lid | cover which concerns on this Embodiment is provided is demonstrated in detail, referring FIGS. 1-5 suitably.

[Container]
The container part 10 is a container part in which a liquid is stored. The container part 10 has the opening part 11 for injecting liquid inside. The liquid is specifically water, but may be tea or juice.

  The opening 11 serves as a water inlet and a drinking mouth. In addition, although a drinking mouth specifically means the part which attaches a mouth directly when a user drinks water, it is not limited to this. The drinking mouth means a water supply opening from which water for the user to drink is taken out. That is, regardless of whether or not the user can directly attach a mouth, the opening 11 is an opening that is used for both water injection to the inside and water supply to the outside.

  In this Embodiment, the container part 10 is not provided with the opening for performing the water injection to an inside and the water supply to the exterior other than the opening part 11. FIG. The opening 11 is the only opening that communicates the inside and the outside of the container 10.

The shape of the container portion 10 may be a bottomed rectangular tube shape, or may be a shape in which the opening 11 is smaller than the bottom portion (so-called bottle shape).

  In this Embodiment, the container part 10 has a heat retention function. Specifically, the container part 10 has a double structure of an inner container and an outer container. The space between the inner container and the outer container is a decompressed space such as a vacuum. Thereby, heat conduction is suppressed between the inner container and the outer container, and the temperature of the water stored inside can be maintained.

  The inner container of the container part 10 is formed using metal materials, such as stainless steel or aluminum. Thereby, since the ultraviolet-ray which the ultraviolet light source part 30 emits can be reflected in the inner surface of the container part 10, water can be disinfected efficiently. In addition, the outer container of the container part 10 is formed from resin materials, such as a polypropylene (PP), for example.

  In addition, the container part 10 does not need to have a heat retention function, and does not need to have a double structure. Moreover, the container part 10 may be shape | molded using the resin material, and the inner surface may be covered with the metal material by the plating process etc.

A female screw is provided on the inner surface of the hole 214 and is screwed with a male screw provided on the outer periphery of the UV lamp 31.

  The back surface 20a is, for example, a metal surface. Specifically, the lower surface of the projection 213 is covered with a metal film such as aluminum. Thereby, since the ultraviolet-ray which the ultraviolet-ray light source part 30 emits can be reflected, water can be sterilized efficiently. The lid base 21 may be formed using a metal material such as stainless steel or aluminum.

  The battery lid 22 is a lid that covers the opening of the lid base 21. The shape of the battery lid 22 is a flat bottomed substantially cylindrical shape. As shown in FIG. 3, the outer surface of the bottom portion 221 of the battery lid 22 is a surface 20 b of the lid portion 20. The battery lid 22 is formed from a resin material such as polypropylene, for example.

  In the present embodiment, as shown in FIG. 5, the protrusion 222 is erected downward from the inner surface of the bottom portion 221 (the surface opposite to the surface 20 b). When viewed from above, a slit is provided around the protrusion 222 except for a part thereof, and the protrusion 222 is movable in the z-axis direction. As shown in FIG. 5, the switch unit 90 is fixed to the upper surface of the protrusion 222. The protrusion 222 moves downward when the switch unit 90 is pressed (turned on), and presses the switch element 42 of the drive circuit unit 40.

  The battery lid 22 may be detachable from the lid base 21, for example. For example, the battery lid 22 is a screw-type lid. Accordingly, the battery cover 50 (specifically, the battery 51) can be replaced by easily removing the battery cover 22 from the cover base 21.

  As shown in FIGS. 4 and 5, the sealing packing 23 is provided on the back surface 20 a side of the lid portion 20. Specifically, the sealing packing 23 is fixed to the outer surface of the convex portion 213 of the lid base 21. As shown in FIG. 3, the shape of the sealing packing 23 is a substantially cylindrical shape. The sealing packing 23 is made of a resin material such as rubber having water resistance, for example.

  The hermetic packing 23 closes the gap between the lid 20 and the container 10 when the lid 20 is attached to the container 10. Specifically, the sealing packing 23 closes between the opening 11 and the convex portion 213. Thereby, the cover part 20 can block | close the opening part 11 completely, and it can prevent that water and light leak from the inside of the container part 10 outside.

  As shown in FIGS. 4 and 5, the waterproof packing 24 is provided between the lid base 21 and the battery lid 22. As shown in FIG. 3, the waterproof packing 24 has a substantially annular shape. The waterproof packing 24 is formed of a resin material such as rubber having water resistance, for example.

  The waterproof packing 24 suppresses moisture from entering the inside of the lid base 21 through the gap between the lid base 21 and the battery lid 22. Thereby, the battery part 50 etc. which are accommodated in the inside of the cover part 20 can be protected from moisture.

[Ultraviolet light source]
The ultraviolet light source part 30 is attached to the back surface 20a side of the lid part 20, and sterilizes the liquid by irradiating the liquid (specifically, water) stored in the container part 10 with ultraviolet rays. The ultraviolet rays to be irradiated are, for example, ultraviolet rays having a peak wavelength in the range of 200 nm to 400 nm. In the present embodiment, the ultraviolet light source unit 30 irradiates ultraviolet rays having a peak wavelength of 253.7 nm as an example.

  In the present embodiment, the ultraviolet light source unit 30 is attached to the lid unit 20, and when the lid unit 20 is removed from the container unit 10 as shown in FIG. 2, the lid unit 20 and the ultraviolet light source unit 30. Is removed as a unit.

  As shown in FIG. 3, the ultraviolet light source unit 30 includes a UV lamp 31, a protective frame 32, a screw 33, and an O-ring 34.

  The UV lamp 31 receives electric power from the drive circuit unit 40 and emits ultraviolet rays. As the UV lamp 31, for example, a glow light bulb (ultraviolet light output 1W) with an input power of 3W can be used, but is not limited thereto. The UV lamp 31 may use an LED (Light Emitting Diode) element that emits ultraviolet rays.

  The UV lamp 31 is provided so as to penetrate the back surface 20a. Specifically, the UV lamp 31 is screwed into the hole 214 and fixed. The UV lamp 31 may be fixed to the lid base 21 using a resin or the like for waterproofing.

  The UV lamp 31 is provided substantially at the center of the back surface 20a when viewed from below. Thereby, it is possible to irradiate the water stored in the container part 10 with ultraviolet rays substantially evenly.

  The UV lamp 31 and the protective frame 32 are inserted from the opening 11 and positioned inside the container 10 as shown in FIGS. 4 and 5 when the lid 20 is attached to the container 10. . As a result, the UV lamp 31 and the protective frame 32 are immersed in the stored water when a predetermined amount (for example, 500 mL) of water is stored in the container 10 (see FIG. 7 described later).

  The protective frame 32 is a three-dimensional lattice-shaped cover for preventing the UV lamp 31 from being damaged. The protective frame 32 is provided so as to surround the UV lamp 31. The protective frame 32 is made of a metal material such as stainless steel, for example.

  The screw 33 is a screw for fixing the protective frame 32 to the lid base 21 (specifically, the convex portion 213), and is, for example, a tapping screw.

  As shown in FIGS. 4 and 5, the O-ring 34 is provided between the UV lamp 31 and the lid 20 (specifically, the hole 214). As shown in FIG. 3, the shape of the O-ring 34 is a substantially annular shape. The O-ring 34 is formed from a resin material such as rubber having water resistance, for example. The O-ring 34 prevents moisture from entering the inside of the lid 20 through the gap between the UV lamp 31 and the hole 214. Thereby, the electric power feeding part of the UV lamp 31 located inside the cover part 20, the drive circuit part 40, the battery part 50, etc. can be protected from moisture.

[Drive circuit section]
The drive circuit unit 40 is housed inside the lid unit 20 and controls turning on and off of the ultraviolet light source unit 30. Specifically, the drive circuit unit 40 controls the timing for turning on and off the ultraviolet light source unit 30. Note that the drive circuit unit 40 may perform control to change the intensity of the ultraviolet light emitted from the ultraviolet light source unit 30 or the period of irradiation with the ultraviolet light.

  In the present embodiment, the drive circuit unit 40 executes a lighting enabled mode in which the ultraviolet light source unit 30 can be turned on and a lighting prohibited mode in which lighting of the ultraviolet light source unit 30 is prohibited. In the lighting enabled mode, the drive circuit unit 40 turns on the ultraviolet light source unit 30 when the switch unit 90 is turned on. In the lighting prohibition mode, the drive circuit unit 40 does not turn on the ultraviolet light source unit 30 even if the switch unit 90 is turned on.

  In the present embodiment, the drive circuit unit 40 can turn on the ultraviolet light source unit 30 in a state where the switch unit 90 is turned on and the lid unit 20 is positioned below the container unit 10. For example, the drive circuit unit 40 can turn on the ultraviolet light source unit 30 in a state where the lid-mounted mug 1 is turned upside down, and can sterilize water contained in the container unit 10. Specifically, the drive circuit unit 40 switches between the lighting enabled mode and the lighting prohibited mode based on at least one state of the open / close sensor unit 60 and the two terminal units 70.

  Specifically, when the lid 20 is attached to the container unit 10, the drive circuit unit 40 is electrically connected by the two terminal units 61 and 62 of the open / close sensor unit 60 being in contact with each other, The ultraviolet light source unit 30 can be turned on. That is, the drive circuit unit 40 executes the lighting enabled mode when the two terminal units 61 and 62 are in an electrically conductive state.

  In addition, when the lid 20 is removed from the container unit 10, the drive circuit unit 40 prohibits the lighting of the ultraviolet light source unit 30 by separating the two terminal units 61 and 62 from each other and becoming non-conductive. To do. That is, the drive circuit unit 40 executes the lighting prohibition mode when the two terminal units 61 and 62 are in a non-conductive state.

  Furthermore, in the present embodiment, when the lid 20 is attached to the container unit 10, the drive circuit unit 40 is configured such that when both of the two terminal units 70 come into contact with water stored in the container unit 10, The ultraviolet light source unit 30 can be turned on when the two terminal units 70 are electrically connected via the water. That is, the drive circuit unit 40 executes the lighting enabled mode when the two terminal units 70 are brought into conduction through water. Specifically, when the lidded mug 1 is turned upside down, both of the two terminal portions 70 are in contact with each other with water stored in the container portion 10 and are made conductive. Thereby, by turning the lid-mounted mug 1 upside down, it is possible to switch from the lighting prohibition mode to the lighting enabled mode almost certainly.

  Further, when at least one of the two terminal portions 70 does not contact the water stored in the container portion 10, the drive circuit portion 40 is brought into a non-conductive state so that the ultraviolet light source portion 30 Prohibit lighting. That is, the drive circuit unit 40 executes the lighting prohibition mode when the two terminal units 70 are in a non-conductive state.

  As described above, in the present embodiment, when both of the two terminal portions 61 and 62 and the two terminal portions 70 are in the conductive state, the drive circuit portion 40 executes the lighting enabled mode. That is, when the switch unit 90 is turned on, the drive circuit unit 40 turns on the ultraviolet light source unit 30.

  In addition, when at least one of the two terminal portions 61 and 62 and the two terminal portions 70 is in a non-conductive state, the drive circuit portion 40 executes the lighting prohibition mode. That is, even if the switch unit 90 is turned on, the drive circuit unit 40 does not turn on the ultraviolet light source unit 30.

  As shown in FIG. 3, the drive circuit unit 40 includes a main circuit board 41, a switch element 42, an LED board 43, and screws 44.

  The main circuit board 41 controls lighting and extinguishing of the ultraviolet light source unit 30 (specifically, the UV lamp 31). That is, the main circuit board 41 is a circuit board for controlling the start and stop of power supply from the battery unit 50 to the UV lamp 31. The main circuit board 41 is, for example, a board on which a microcomputer (microcontroller) is mounted.

  The main circuit board 41 operates based on a control signal from the switch element 42. Further, the main circuit board 41 switches between the lighting enabled mode and the lighting prohibited mode based on at least one state of the open / close sensor unit 60 and the two terminal units 70.

  When the switch unit 90 is turned on in the lighting enabled mode, the main circuit board 41 turns on the ultraviolet light source unit 30 for a predetermined period. In addition, the said period is a period sufficient for the unsterilized water put into the container part 10 to be sterilized. The said period is a period determined based on the capacity | capacitance of the container part 10 and the intensity | strength of the ultraviolet-ray of the ultraviolet light source part 30, for example.

  The switch element 42 detects the pressing (ON) of the switch unit 90 and outputs a control signal to the main circuit board 41. The switch element 42 is mounted on the LED board 43, for example.

  In the present embodiment, when the switch element 42 detects that the switch unit 90 is turned on, the switch element 42 outputs an on signal for starting lighting of the UV lamp 31 to the main circuit board 41 as a control signal. When the ON signal is input, the main circuit board 41 turns on the UV lamp 31 in the lighting-enabled mode.

  The LED substrate 43 is a substrate on which an LED element (not shown) is mounted. The LED element emits visible light. The light emitted from the LED element passes through the display unit 80 and is emitted to the outside.

  In the present embodiment, the LED substrate 43 controls the lighting of the LED elements according to the lighting state of the UV lamp 31. Specifically, the LED board 43 blinks the LED elements while the UV lamp 31 is lit, that is, during the period when the UV lamp 31 emits ultraviolet rays. In addition, the LED substrate 43 continuously turns on the LED elements after the UV lamp 31 is turned on.

  Furthermore, the LED substrate 43 turns off the LED element when the lid 20 is removed from the container 10 after the UV lamp 31 is turned on. For example, the LED substrate 43 is electrically connected to the open / close sensor unit 60, and turns off the LED element when the open / close sensor unit 60 detects that the lid 20 has been removed from the container unit 10.

  The screw 44 is a screw for fixing the main circuit board 41 to the lid base 21 and is, for example, a tapping screw. In the present embodiment, the main circuit board 41 is fixed to the bottom portion 211 of the lid base 21 with two screws 44 and two screws 54. For example, the LED substrate 43 is placed on a protrusion (not shown) provided inside the lid base 21.

[Battery section]
The battery unit 50 is a battery unit that is housed inside the lid unit 20 and supplies power to the ultraviolet light source unit 30. In the present embodiment, the battery unit 50 supplies power not only to the ultraviolet light source unit 30 but also to the LED elements of the display unit 80 by supplying power to the drive circuit unit 40.

  As shown in FIG. 3, the battery unit 50 includes a battery 51, two battery terminals 52, a battery receiver 53, and a screw 54.

  The battery 51 is an example of a power source that supplies power to the drive circuit unit 40. The battery 51 is, for example, a lithium battery, but is not limited to this. The battery 51 may be either a primary battery or a secondary battery.

  The two battery terminals 52 are arranged such that one contacts the positive electrode of the battery 51 and the other contacts the negative electrode of the battery 51. The two battery terminals 52 are formed using a conductive material such as metal, for example. The two battery terminals 52 supply the power of the battery 51 to the drive circuit unit 40.

  The battery receiver 53 is a member for supporting the battery 51. The battery receiver 53 is formed using, for example, an insulating resin material. In the present embodiment, the battery receiver 53 has a recess in which about half of the battery 51 is accommodated. The battery 51 is accommodated in the recess, and the upper part is held by the battery lid 22. Thereby, the movement of the battery 51 inside the lid portion 20 is restricted, and the reliability of power supply to the drive circuit portion 40 can be improved.

  The screw 54 is a screw for fixing the battery receiver 53 to the lid portion 20. In the present embodiment, as shown in FIG. 5, the screw 54 is fixed by sandwiching the main circuit board 41 between the battery receiver 53 and the lid base 21. The screw 54 is, for example, a tapping screw.

  The battery 51 may be detachable. That is, in the present embodiment, the battery 51 may be replaceable. Thereby, when the capacity of the battery 51 becomes small (or disappears), the battery 51 having a small capacity can be replaced with a new battery 51. For example, since the battery 51 is exposed to the outside by removing the battery lid 22 from the lid base 21, the battery 51 can be easily replaced.

[Opening / closing sensor part (first terminal part)]
The open / close sensor unit 60 detects whether or not the lid unit 20 is attached to the container unit 10. That is, the open / close sensor unit 60 detects whether or not the lid unit 20 blocks the opening 11 of the container unit 10.

  In the present embodiment, the open / close sensor unit 60 is provided on the back surface 20 a of the lid unit 20. Specifically, as shown in FIG. 4, the open / close sensor unit 60 is fixed in the recess 212 of the lid base 21. The open / close sensor unit 60 includes two terminal units 61 and 62 and a buffer member 63.

  6A and 6B are partially enlarged sectional views showing a region VI of FIG. FIG. 6A is a diagram illustrating two terminal portions 61 and 62 when the lid portion 20 is not attached to the container portion 10. FIG. 6B is a diagram illustrating the two terminal portions 61 and 62 when the lid portion 20 is attached to the container portion 10.

  The two terminal portions 61 and 62 are an example of two conductive first terminal portions that are electrically connected to the drive circuit portion 40. The two terminal portions 61 and 62 are, for example, a plate member made of metal such as copper, aluminum, stainless steel, or an alloy of nickel and copper, or conductive rubber.

  As shown in FIG. 6A, the terminal portion 61 and the terminal portion 62 are separated from each other when the lid portion 20 is not attached to the container portion 10. That is, the terminal part 61 and the terminal part 62 are in a non-conductive state.

  When the two terminal portions 61 and 62 are in a non-conductive state, the ultraviolet light source unit 30 is not lit even if the lighting prohibition mode is maintained and the switch unit 90 is turned on. For this reason, when the cover part 20 is not attached to the container part 10, the ultraviolet light source part 30 does not light up. Therefore, it is possible to prevent the ultraviolet light source unit 30 from erroneously irradiating ultraviolet rays in a state where the lid unit 20 is removed from the container unit 10, and safety can be improved.

  On the other hand, as shown in FIG. 6B, in a state where the lid portion 20 is attached to the container portion 10, the terminal portion 62 is pressed by a part of the container portion 10 (specifically, the edge of the opening portion 11). Elastically deforms. The terminal part 62 is, for example, a metal leaf spring. Thereby, the terminal part 62 contacts the terminal part 61 and is electrically connected.

  When the two terminal portions 61 and 62 are in the conductive state, the lighting prohibition mode is switched to the lighting enabled mode. That is, when the switch unit 90 is turned on, the drive circuit unit 40 can turn on the ultraviolet light source unit 30. The terminal portion 62 may not be a leaf spring, but may be a conductive member that can move in response to pressing by the container portion 10.

  The buffer member 63 is an elastic member provided so that the terminal portion 62 does not directly contact the container portion 10. The buffer member 63 is pressed by the container part 10 and elastically deforms. The buffer member 63 is made of a resin material such as rubber, for example.

[Terminal part (second terminal part)]
The two terminal portions 70 are an example of two conductive second terminal portions that are electrically connected to the drive circuit portion 40. The two terminal portions 70 are, for example, rod members made of metal such as stainless steel, aluminum, copper, or an alloy of nickel and copper.

  The two terminal portions 70 are arranged on the back surface 20a of the lid portion 20 so as to be separated from each other. In the present embodiment, the two terminal portions 70 protrude from the back surface 20 a of the lid portion 20. As shown in FIG. 5, the two terminal portions 70 pass through the convex portion 213 (back surface 20 a) and are connected to the main circuit board 41.

  FIG. 7 is a partial cross-sectional view showing a state in which water 2 is stored in the lidded mug 1 according to the present embodiment and can be sterilized. Specifically, FIG. 7 shows a cross section taken along line VV of FIG.

  When water is sterilized, the lidded mug 1 is turned over and used in the present embodiment. When the water 2 is put inside the container part 10 and the mug 1 with the lid is turned over, both the two terminal parts 70 come into contact with the water 2. Both of the two terminal portions 70 come into contact with the water 2, whereby the two terminal portions 70 are electrically connected via the water 2. Thereby, the drive circuit unit 40 can turn on the ultraviolet light source unit 30 (UV lamp 31). That is, when both of the two terminal portions 70 come into contact with water, the lighting prohibition mode is switched to the lighting enabled mode.

  When at least one of the two terminal portions 70 does not come into contact with the water 2, the lighting prohibition mode is maintained. In the present embodiment, when the lidded mug 1 is in the normal position (that is, when the lid portion 20 is located above the container portion 10), the two terminal portions 70 do not come into contact with the water 2. Is maintained. Therefore, when the lidded mug 1 is in the normal position, the ultraviolet light source unit 30 is not turned on even if the switch unit 90 is turned on.

  When a sufficient amount of water (for example, 500 mL, which is a specified capacity) is placed in the container part 10 so as to come into contact with both of the two terminal parts 70, it can be lit even when the lidded mug 1 is in the normal position. The mode is executed. For this reason, when the switch part 90 is turned on, the ultraviolet light source part 30 can irradiate ultraviolet rays, and the water 2 can be sterilized.

  However, when the amount of the water 2 put in the container part 10 is small, even if the switch part 90 is turned on without the two terminal parts 70 coming into contact with the water 2, no ultraviolet rays are irradiated. For this reason, the user may mistakenly recognize that the water 2 has been sterilized by pressing the switch unit 90.

  In the present embodiment, even when the amount of the water 2 put in the container portion 10 is small, the ultraviolet light can be irradiated almost certainly by turning over the lidded mug 1. Thereby, the water 2 can be sterilized almost certainly.

  In addition, even when a sufficient amount of water 2 is stored in the container part 10, if the lid part 20 is not attached to the container part 10, the two terminal parts 70 do not contact the water 2, The ultraviolet light source unit 30 is not turned on. Therefore, it is possible to prevent the ultraviolet light source unit 30 from erroneously irradiating ultraviolet rays in a state where the lid unit 20 is removed from the container unit 10, and safety can be improved.

[Display section]
The display unit 80 displays the lighting state of the ultraviolet light source unit 30. In the present embodiment, display unit 80 is a substantially annular resin member. Specifically, the display unit 80 is formed by injection molding using a translucent resin material into which a diffusion material such as silica is diffused. For example, the display unit 80 is formed integrally with the battery lid 22 by two-color molding.

  The display unit 80 transmits light emitted from the LED elements of the LED substrate 43 and diffuses (scatters) the light using a diffusing material. Since the lighting state of the LED element changes according to the lighting state of the ultraviolet light source unit 30 (specifically, the UV lamp 31), the display unit 80 can display the lighting state of the UV lamp 31.

  Specifically, the display unit 80 blinks while the ultraviolet light source unit 30 is lit, and continuously lights after the ultraviolet light source unit 30 is turned on. Blinking lighting is to repeatedly increase and decrease the amount of light, for example, to repeatedly turn on (100%) and turn off (0%). The repetition period is not particularly limited. Continuous lighting is to continuously emit light with a constant light amount (for example, 100%).

  Thus, since the lighting state (display state) of the display unit 80 changes according to the lighting state of the ultraviolet light source unit 30, the user can enter the container unit 10 by checking the lighting state of the display unit 80. You can grasp the state of water. For example, when the display unit 80 is lit in a blinking manner, it is understood that water is being sterilized. When the display unit 80 is continuously lit, it can be seen that the sterilization of the water is finished and it can be used as drinking water. That is, when the display unit 80 is continuously lit, the user can remove the lid 20 and drink the water stored in the container unit 10.

  The display unit 80 is turned off when the lid unit 20 is removed from the container unit 10. Thereby, when the display part 80 is light-extinguished, it means that the cover part 20 is removed from the container part 10 at least once, and ultraviolet irradiation is not performed after that. That is, the water stored in the container part 10 may be unsterilized water. For this reason, the user can be prompted to sterilize before drinking water.

  In the present embodiment, the display unit 80 emits light not only from the top surface but also from the side surface. Thereby, even if it is a case where the lid | cover mug 1 is turned over and an upper surface cannot be seen, the irradiation state of the display part 80 can be confirmed.

  The upper surface of the display unit 80 and the upper surface (that is, the surface 20b) of the lid unit 20 are substantially flush. Thereby, when the mug 1 with a lid is turned over, it can be made to stand on a horizontal surface easily.

[Switch part]
The switch unit 90 switches the drive circuit unit 40 on and off. In the present embodiment, the switch unit 90 is a push-down physical button, but is not limited thereto. The switch unit 90 may be a slide type button or the like.

  In the present embodiment, when the switch unit 90 is pressed (turned on), the switch element 42 is pressed through the protrusion 222 of the battery lid 22. As a result, the drive circuit unit 40 can be informed that the switch unit 90 is turned on. When the switch unit 90 is turned on, the ultraviolet light source unit 30 sterilizes water by emitting ultraviolet rays in the lighting-enabled mode.

  Note that the switch portion 90 has a button portion that protrudes upward, and is formed so as to be easily pressed by the user. At this time, the switch unit 90 does not protrude above a flat surface formed by the upper surface of the display unit 80 and the upper surface of the lid unit 20.

  Accordingly, the lid-attached mug 1 can be turned over and placed on a horizontal plane without the switch 90 being obstructed. Since the lidded mug 1 stands on a horizontal surface when turned upside down, it can be left in a turned over state during the period of ultraviolet irradiation.

[Operation and usage]
Then, operation | movement and the usage method of the mug 1 with a cover concerning this Embodiment are demonstrated using FIG. FIG. 8 is a diagram for explaining the operation and usage of the lidded mug 1 according to the present embodiment.

  First, as shown in FIG. 8A, the user 5 (see (f)) removes the lid portion 20 of the lidded mug 1 and puts water 2 into the container portion 10 through the opening 11. Add water. For example, tap water is poured from the faucet 3 as water 2. The faucet 3 is, for example, a household faucet, and the water 2 is tap water (unsterilized water).

  Next, as shown in FIG. 8B, the user 5 closes the opening 11 by attaching the lid 20 to the container 10. By appropriately attaching the lid portion 20 to the container portion 10, the terminal portions 61 and 62 of the open / close sensor portion 60 come into contact and become conductive (see FIG. 6B).

  By attaching the lid part 20 to the container part 10, the water 2 put in the container part 10 does not leak outside. Therefore, the user 5 can carry the lidded mug 1.

  Next, as shown in FIG. 8C, the lidded mug 1 is turned upside down. Thereby, both the two terminal parts 70 contact the water 2, and will be in a conduction | electrical_connection state via the water 2 (refer FIG. 7). Thereby, the drive circuit unit 40 is switched from the lighting prohibition mode to the lighting possible mode.

  In the state where the lid 20 is removed ((a) of FIG. 8), since the terminal portions 61 and 62 and the two terminal portions 70 are both non-conductive, the lighting prohibition mode is maintained. . For this reason, even if the switch unit 90 is turned on, the ultraviolet light source unit 30 is not turned on.

  Next, the user 5 presses the switch unit 90 with, for example, the finger 4 in a state where the lidded mug 1 is turned over. Thereby, as shown in FIG. 8D, the ultraviolet light source unit 30 (specifically, the UV lamp 31) emits ultraviolet rays. At this time, the display unit 80 blinks. Since the display unit 80 also emits light from the side surface, the user 5 can check the lighting state of the display unit 80 even when the lidded mug 1 is turned over and placed on a desk or the like.

  When a predetermined period elapses, the ultraviolet light source unit 30 is turned off as shown in FIG. The display unit 80 is continuously turned on as the ultraviolet light source unit 30 is turned off.

  Finally, as shown in (f) of FIG. 8, the lid 20 is removed from the container 10 at an arbitrary timing of the user 5, and the water 2 is used as drinking water through the opening 11. The water 2 at this time is sterilized water and is suitable for drinking. At this time, since the lid part 20 is removed from the container part 10, the display part 80 is turned off.

[Effects, etc.]
As described above, the lidded mug 1 according to the present embodiment has the opening 11 serving as the liquid injection port and the drinking port, and closes the container 10 and the opening 11 in which the liquid is stored. For this purpose, a lid 20 that can be attached to and detached from the container 10 and an ultraviolet light source 30 that is attached to the back surface 20a side of the lid 20 and sterilizes the liquid by irradiating the liquid stored in the container 10 with ultraviolet rays. A drive circuit unit 40 that is housed inside the lid unit 20 and controls turning on and off of the ultraviolet light source unit 30; a switch unit 90 that switches on and off of the drive circuit unit 40; and a lighting state of the ultraviolet light source unit 30 Display unit 80 and two conductive terminal units 70 electrically connected to the drive circuit unit 40, which are arranged on the back surface 20 a of the lid unit 20 so as to be separated from each other. 70, and the drive circuit unit 40 has a lid. When 20 is attached to the container part 10, (i) when both of the two terminal parts 70 come into contact with the liquid stored in the container part 10, the two terminal parts 70 are electrically connected via the liquid. (Ii) when at least one of the two terminal portions 70 does not come into contact with the liquid stored in the container portion 10, the two terminal portions 70 are not in contact with each other. By turning on the conductive state, the ultraviolet light source unit 30 is prohibited from being turned on.

  Thereby, as shown in FIG. 8, sterilization of water can be easily performed with the lid-mounted mug 1 alone. The user 5 can freely carry the lidded mug 1 containing sterilized water, and can use the sterilized water as drinking water through the opening 11 at a favorite place and a favorite time. That is, the lidded mug 1 according to the present embodiment is excellent in portability and can easily sterilize water.

  In addition, for example, drinking water put in a commercially available plastic bottle may be bred with various germs from the mouth or air when opened once. That is, even if it is sufficiently safe at the time of purchase, the state is not always maintained. On the other hand, according to the mug 1 with a lid | cover which concerns on this Embodiment, since the user 5 can sterilize just before drinking, highly safe drinking water can always be provided.

  Here, when the two terminal portions 70 are not provided, when the user 5 puts water into the container portion 10 but the amount of water injected is small, the following problem may occur. That is, even if the user 5 turns on the switch unit 90 and is irradiated with ultraviolet rays from the ultraviolet light source unit 30, the water 2 may not be sufficiently sterilized if the amount of water injection is small and the ultraviolet light source unit 30 is not immersed in the water 2. There is sex. However, as long as the switch unit 90 is turned on, the user 5 may misunderstand that the sterilizing function of the lidded mug 1 operates properly and the water 2 can be sterilized and used as drinking water.

  On the other hand, since the lidded mug 1 according to the present embodiment includes the two terminal portions 70, if both of the terminal portions 70 are not in contact with the water 2, the ultraviolet light source 30 is not lit, The display unit 80 can display “OFF” as the lighting state of the ultraviolet light source unit 30. Therefore, the user 5 confirms the state (display) of the display unit 80 to determine whether the ultraviolet light source unit 30 is irradiating ultraviolet rays, that is, whether the sterilizing function of the lidded mug 1 is operating properly. It is possible to grasp whether or not. Therefore, according to the mug 1 with a lid, the water 2 can be sterilized almost certainly.

  For example, when the amount of water injection is small, both the two terminal portions 70 provided on the back surface of the lid portion 20 can be brought into contact with the water 2 by turning the lid-mounted mug 1 upside down. That is, the user 5 can sterilize the water 2 by turning over the lidded mug 1 without necessarily filling the container portion 10 with the water 2 or close to it. Therefore, since a required amount can be sterilized when necessary, user convenience can be enhanced.

  Further, for example, the drive circuit unit 40 can turn on the ultraviolet light source unit 30 in a state where the switch unit 90 is turned on and the lid unit 20 is positioned below the container unit 10.

  Thus, since the ultraviolet light source part 30 can be turned on in a state where the lid part 20 is located below the container part 10, for example, when the lidded mug 1 is turned upside down, the sterilization function is properly performed. It can be operated. In other words, while the user 5 is forced to turn over the lidded mug 1, the flipping operation itself helps to confirm the sterilization operation state, and provides the lidded mug 1 with a sterilization function that is extremely secure. can do.

  Further, for example, the display unit 80 blinks while the ultraviolet light source unit 30 is lit, and continuously lights after the ultraviolet light source unit 30 is turned on.

  Accordingly, the display unit 80 blinks during sterilization, and the display unit 80 is continuously lit after the sterilization is completed. Therefore, the user 5 can easily understand the sterilization state, that is, whether or not the water 2 can be consumed. it can.

  In addition, for example, the display unit 80 is turned off when the lid unit 20 is removed from the container unit 10.

  Thereby, after completion | finish of sterilization, after the user 5 removes the cover part 20 from the container part 10 in order to drink sterilization water, the display part 80 turns off. That is, while the display unit 80 is lit, it indicates that the water 2 in the container unit 10 is in a sterilized safe state, so that the user 5 can use the water 2 as drinking water with confidence. .

  On the other hand, once the lid part 20 is removed from the container part 10, there is a risk that various germs and the like enter through the opening part 11. For this reason, the water 2 put in the container part 10 is not necessarily safe. According to the lidded mug 1 according to the present embodiment, the display unit 80 is turned off, indicating that it is not sterilized or that the lid unit 20 has been opened after sterilization. 5 can recognize that the water 2 in the container part 10 may not be safe. Therefore, it is possible to provide the lidded mug 1 with a sterilizing function that is very secure.

  Further, for example, the surface 20b opposite to the back surface 20a of the lid part 20 is substantially flat, and the lidded mug 1 places the surface 20b on a horizontal plane when the lid part 20 is attached to the container part 10. Be independent when

  Thereby, for example, the lidded mug 1 can be placed over the desk or the like. Therefore, since the user 5 does not need to hold the lidded mug 1 during the sterilization process, the user convenience can be improved.

(Other)
As described above, the lidded mug according to the present invention has been described based on the above embodiment and the modifications thereof, but the present invention is not limited to the above embodiment.

  For example, in the above-described embodiment, the example in which the two terminal portions 70 are metal rod-shaped members has been described, but the present invention is not limited thereto. For example, each of the two terminal portions 70 is a plate-like metal member, and may be provided so as to cover a part of the back surface 20 a of the lid portion 20. In the above embodiment, the lid-mounted mug 1 is turned over and used, so that the two terminal portions 70 do not have to protrude from the back surface 20a.

  For example, in the above-described embodiment, when water is sterilized, the lid-mounted mug 1 is turned upside down. However, the present invention is not limited thereto. The mug 1 with a lid can be laid sideways and used.

  Further, for example, the lidded mug 1 may have a configuration for urging the user to turn the lidded mug 1 over. For example, a predetermined character string (for example, a logo type) printed upside down may be provided on the side surface of the lid 20 (or the container 10). When the lid-mounted mug 1 is in the normal position, the character string is turned upside down, thereby urging the lid-mounted mug 1 to be turned over.

  Further, for example, in the above-described embodiment, the switch unit 90 is pressed (turned on) after the lid-mounted mug 1 is turned over. However, after the switch unit 90 is pressed, the lid-mounted mug 1 may be turned over. Good. Specifically, the drive circuit unit 40 may suspend processing (specifically, turning on the ultraviolet light source unit 30) for the pressing of the switch unit 90 for a predetermined period. The drive circuit unit 40 may turn on the ultraviolet light source unit 30 when the lighting prohibition mode is switched to the lighting enabled mode while it is on hold. As a result, when the switch unit 90 is pressed, the drive circuit unit 40 is in the lighting prohibition mode, and thus the ultraviolet light source unit 30 is not turned on, but the lidded mug 1 is turned over and turned on. The mode is switched to the enable mode, and the ultraviolet light source unit 30 is turned on.

  Further, for example, in the above-described embodiment, the example in which the lidded mug 1 includes the open / close sensor unit 60 has been described, but the present invention is not limited to this. The lidded mug 1 may not include the open / close sensor unit 60.

  Moreover, for example, a through-hole for penetrating the lid 20 and taking out drinking water may be provided. The through hole communicates the inside of the container portion 10 with the external space, and a lid may be provided at the opening on the external space side. Thereby, even if it does not remove the cover part 20, sterilization water can be used for drinking.

  In addition, the embodiment can be realized by arbitrarily combining the components and functions in each embodiment without departing from the scope of the present invention, or a form obtained by subjecting each embodiment to various modifications conceived by those skilled in the art. Forms are also included in the present invention.
