Abstract
Glass-ceramic containers and methods of making glass ceramic containers with high transparency and fracture toughness suitable for use as, for example a beverage or food container, such as for example, a baby bottle or personal hydration bottle. The glass ceramic containers may have an average wall thickness in the range of 1 mm to 2.5 mm and a fracture toughness of 1 MPa*m{circumflex over ( )}1/2 or more.
Claims21
A glass-ceramic container, comprising:
- a body comprising a transparent glass-ceramic material and a hollow interior defined by a circumferential sidewall comprising an average wall thickness in a range from 1 mm to 1.25 mm, the body further comprising, a top end, a spout and neck portion adjacent the top end, a bottom end, a base portion adjacent the bottom end, and a middle portion disposed between the base portion and the spout and neck portion;
- and
- wherein a fracture toughness of the glass-ceramic material is 1 MPa*m{circumflex over ( )}1/2 or more and an exterior surface of the body does not comprise a coating.
