Components
The Primus TrailBreak Lunch Jug consists of the following main components:
- Insulated Body: The main container, constructed from durable stainless steel with double-wall vacuum insulation.
- Screw Cap: A secure, leak-proof lid designed to seal the contents and enhance thermal retention.
Setup
Before first use, and after each use, clean the lunch jug thoroughly according to the maintenance instructions.
- Pre-heat/Pre-cool (Optional but Recommended): For optimal temperature retention, pre-heat the jug with hot water or pre-cool with cold water for 5-10 minutes before adding your food.
- For hot food: Fill the jug with boiling water, close the lid, and let it sit. Empty the water before adding food.
- For cold food: Fill the jug with ice water, close the lid, and let it sit. Empty the water before adding food.
- Fill with Food/Liquid: Carefully fill the jug with your desired hot or cold food or liquid. Do not overfill; leave a small space at the top for the lid.
- Secure the Lid: Screw the cap on tightly to ensure a complete seal.
Operating
Using your Primus TrailBreak Lunch Jug is straightforward:
- Transport: Carry the sealed jug in an upright position to prevent any potential leaks, although the screw cap is designed to be leak-proof.
- Opening: To open, unscrew the cap counter-clockwise. Be cautious if the contents are hot, as steam may escape.
- Serving: The wide mouth of the jug allows for easy eating directly from the container or pouring contents into a bowl.
- Re-sealing: After use, or if you are not finished with the contents, screw the cap back on tightly to maintain temperature.
Maintenance
Proper care will extend the life and performance of your lunch jug:
- Cleaning:
- Wash the jug and lid by hand with warm water and mild dish soap.
- Use a bottle brush for thorough cleaning of the interior.
- Rinse thoroughly with clean water.
- Allow all parts to air dry completely before reassembling or storing to prevent odors and mildew.
- Deep Cleaning: For stubborn stains or odors, a mixture of baking soda and warm water can be used. Let it sit for a few hours or overnight, then rinse thoroughly.
- Storage: Store the jug with the lid slightly ajar to allow air circulation and prevent odors.
- Avoid Abrasives: Do not use abrasive cleaners, bleach, or scrubbers that could scratch the finish or damage the insulation.
