collapsible cup

Many collapsible cups include an attached lid with two drinking openings—one sized for sipping and one for a straw—and a closing mechanism that seals the unused nozzle to reduce spills.

The collapsible design folds the bottom into itself so the cup becomes much more compact and easy to carry. Product details describe these cups as reusable, plastic-free, and designed for portability.

Some collapsible cups have interior measurement lines marked in ounces to help track contents, and the cup can be filled and frozen to make ice cubes.
