| Abstract: |
A ceramic cup has a sound generating circuit at the bottom to produce a melody when the cup is lifted up from, for example, a table. This gives a wonder and pleasant impression for those using it. The synthetic resin is cast into a hard layer in generally integral with the bottom of the cup, making the layer believe to be a part of the cup, at the same time, rendering the layer substantially immune to inadvertent removal.

First Claim:
Show all 2 claims |
What is claimed is:
1. An eating utensil having a sound generating means comprising:
- (a) a flanged bottom portion providing the circumferential peripheral bottom of an eating utensil which contacts a setting plane so as to be obscured from ambient light at the time of placing the bottom of the eating utensil on the setting plane;
- (b) a recessed portion within the bottom of said eating utensil so as to be in concentrical relationship with said flanged bottom portion;
- (c) an electronic circuit located in the recessed portion of said eating utensil to generate a sound upon energization;
- (d) a battery cell incorporated into said electronic circuit as a power source thereof;
- (e) a light permeable, cast synthetic resin layer positioned within said recessed portion in contact with the inside of said flange to provid a liquid-tight seal for said electronic circuit;
- (f) a photo-sensitive switch provided is said electronic circuit to be exposed to the ambient light transmitted through said synthetic resin layer to energize said electronic circuit;
- (g) a translucent, liquid-impermeable sheet, the area of which is somewhat smaller than that of said flanged bottom portion provided between said electronic circuit and said light permeable layer to protect said electronic circuit against the synthetic resin at the time of casting, and a translucent binder paper sheet having a sticky adhesive at both sides placed between said electronic circuit and said translucent, liquid-impermeable sheet to fix said sound generating electronic circuit in place.
