It sounds like you’re describing an old water bottle with some level of dissipation, which could refer to various forms of degradation, such as:

• Wear and tear: The bottle may show signs of use, like scratches, dents, or fading.
• Loss of insulation performance: If the bottle is insulated, it might not keep drinks cold or hot as effectively anymore.
• Material degradation: The plastic or other materials may have weakened over time, potentially affecting its strength or seal.

If you are selling or describing this water bottle, here’s an example of how you might phrase it:

Used Water Bottle

• Condition: Gently used with visible signs of wear, such as scratches and fading.
• Dissipation: The bottle may not retain temperature as well as when new, or show slight degradation in material quality.
