PROBLEM TO BE SOLVED: To make the model number and control items other than the model number included in one common sign, make the same sign utilizable in both of the model number inspection, quality control inspection, etc., and reduce a load on both sides of a bottle supplier and a food supplier. SOLUTION: This glass bottle is provided with signs 32 arranged at the nearly equal interval along a virtual circular locus R in the bottle bottom of the glass bottle, the signs 32 having a first sign 32a, a second sign 32b marked at a position separated from the first sign 32a by about >=1/4 circumference of the circle, plural model number display signs 32c to 321 marked at the nearly equal interval in the residual about 3/4 circumference of the circle from the second sign 32b to the first sign 32a and the model number display signs divided with two bounds or three bounds from the side of the second sign 32b along the virtual circular locus R. The glass bottle is composed so that the control items other than the model number can be controlled by changing at least any one model number display sign of the model number display sings marked in sections A to E and reading the change.
