Freezing can stress a container and its closure, especially when expansion space or freezer suitability is inadequate. Forcing the cap may expose you to a damaged or pressurised container.
What the observation tells you
This is particularly concerning with carbonated drinks, which should not be stored frozen. A bottle that still looks intact can have hidden cracks. Do not strike it against the freezer edge or use boiling water to release the closure.
A useful next step
Handle the situation cautiously outside the appliance using appropriate safety guidance. Review packaging suitability before future freezing and keep vulnerable food away from possible glass fragments.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
