Claims11
A glass container comprising:
- a glass body having a lateral portion defined by a wall, a lower portion defined by a bottom having an inner surface and substantially flat outer surface, and an upper portion defined by a mouth, said mouth having a rim and said wall having a maximum outer diameter that is equal to or greater than a maximum outer diameter of the mouth;
- a first glass partition integral with the glass body, extending from the inner surface of the bottom into the mouth and terminating below the rim, the first glass partition also extending from a first proximal point on the wall to a first distal point on the wall;
- a second glass partition integral with the glass body, extending from the inner surface of the bottom into the mouth and terminating below the rim, the second glass partition also extending from a second proximal point on the wall to a second distal point on the wall;
- a first concave compartment defined by a first portion of the wall, a first portion of the first glass partition, and a first portion of the inner surface of the bottom;
- a second concave compartment defined by a second portion of the wall, a first portion of the second glass partition, and a second portion of the inner surface of the bottom;
- and
- a third concave compartment located between the first concave compartment and second concave compartment, the third concave compartment defined by third and fourth portions of the wall, a second portion of the first glass partition, a second portion of the second glass partition, and a third portion of the inner surface of the bottom;
- wherein
- a first part defined between the first portion of the first glass partition and the second portion of the first glass partition is solid glass,
- a second part defined between the first portion of the second glass partition and the second portion of the second glass partition is solid glass, and
- where the area between the inner surface of the bottom and substantially flat outer surface of the bottom is solid glass.
