Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a cup such as a tumbler that emits light.

(Prior Art) Conventionally, a type of lighting only when a cup is lifted (see Japanese Patent Laid-Open No. 52-20179 and Japanese Laid-Open Utility Model No. 53-124877)
There is a known type (see Japanese Utility Model Laid-Open No. 3-23042) in which the light is turned on only when the conductors are connected by a resistor such as a finger.

(Problems to be Solved by the Invention) The former described in the above-mentioned prior art requires a switch such as a micro switch having an operating portion that projects downward when the cup is lifted, and the latter is also a resistor such as a finger. An amplifier circuit or the like composed of two-stage transistors that operate due to the potential difference generated by the connection is required, and both have the drawbacks that the configuration is complicated and the cost is high.

The present invention aims to provide a new cup in which the above defects are eliminated.

(Means for Solving the Problems) In order to achieve the above-mentioned object, a cup according to the present invention has a bottom body having an upper side wall made of a transparent plate which is detachably fixed to the bottom of the cup body, The battery 5 and the light-emitting body such as a mini electric lamp that receives power from the battery 5 and lights up are fixed in a state where the light emitting body such as a mini electric lamp emits light toward the inside of the cup main body through the bottom wall of the cup main body. At the same time, the pair of electrodes 7, 7'is fixed to the lower side wall of the bottom body so as to be exposed on the lower surface, and the electrodes 7, 7'are made to be in a conducting state only when the electrodes 7 and 7'are short-circuited. It consists of

(Operation) Since the cup according to the present invention has the above-mentioned configuration,
When this is placed on, for example, a metal coaster or a metal-plated coaster, when a pair of electrodes 7 and 7'on the lower surface come in contact with the same, a light emitting body such as a mini electric lamp drives the power receiving circuit from the battery. Power is received via the light. The light emitted by this lighting is like a mood stand that illuminates the drink in the cup body such as the tumbler and illuminates the cup body such as the tumbler.

(Effects of the Invention) The present invention has a bottom body having an upper side wall made of a transparent plate that is detachably fixed to the bottom of a cup body, and a battery 5 and a miniature electric light that is lit by receiving power from the battery 5. The isoluminous body is fixed so that the miniature luminous body such as a miniature electric lamp emits light toward the inside of the cup body through the bottom wall of the cup body, and a pair of electrodes 7, 7'on the lower side wall of the bottom body. Is fixed to be exposed to the lower surface, and the electrodes 7 and 7'are made to energize the power receiving circuit only when they are short-circuited. It does not require a switch or an amplifier circuit composed of two-stage transistors, and the overall configuration is extremely simple and can be provided at a reasonable cost.

(Embodiment) In the embodiment shown in the drawings, a bottom body 4 having an upper side wall 2 made of a transparent plate is detachably fixed to the bottom of a tumbler main body 1, and a rechargeable battery 5 and a battery 5 are mounted in the bottom body 4. The miniature electric lamp 6 which is turned on by receiving electricity from the bottom electric element 6 is fixed while the miniature electric lamp 6 emits light toward the inside of the tumbler body 1 through the bottom wall 1 ′ of the tumbler body 1. A pair of electrodes 7, 7'is fixed to the side wall 3, and the electrodes 7, 7'are made conductive only when the electrodes 7, 7'are short-circuited.
