Setup
1. Unpacking
The package includes one (1) Tupperware Eidgenosse Plus container with its corresponding lid.
2. Initial Cleaning
Before first use, wash the container and lid thoroughly. You can use warm soapy water or place them in a dishwasher. Rinse well to remove all soap residue and dry completely before storing or using.
Operating Instructions
1. Recommended Usage
This container is suitable for storing a variety of dry and semi-dry food items. Recommended uses include:
- Butter
- Biscuits
- Cereals
- Cakes and Pastries
- Pet Food
- Bread
- Pasta
- Rice
- Spices
2. Sealing the Container
To ensure an airtight seal, align the lid properly with the container's rim. Press down firmly on all four sides of the lid until you hear a click, indicating it is securely closed. This helps to keep contents fresh.
3. Microwave Use
The Tupperware Eidgenosse Plus is microwave-safe. When heating food in the microwave, ensure the lid is not fully sealed to allow steam to escape. This prevents pressure buildup and potential damage to the container.
4. Stackability
Designed with a special feature for efficient storage, these containers are stackable. This allows you to maximize space in your pantry, refrigerator, or cupboards.
Maintenance and Care
1. Cleaning
The Tupperware Eidgenosse Plus container and its lid are dishwasher-safe. For hand washing, use a soft sponge and mild dish soap. Avoid using abrasive cleaners, scouring pads, or harsh chemicals, as these can scratch or damage the plastic surface.
2. Drying and Storage
Ensure the container and lid are completely dry before storing them to prevent the buildup of odors or mildew. For long-term storage, it is recommended to store the container with the lid slightly ajar or separately to allow air circulation and prevent odors from becoming trapped.
Troubleshooting
1. Lid Not Sealing Properly
- Check for Debris: Ensure the rim of the container and the lid are clean and free from any food particles or debris that might obstruct the seal.
- Inspect for Damage: Examine the lid and container for any cracks, warps, or damage that could compromise the seal.
- Proper Alignment: Make sure the lid is correctly aligned with the container before pressing down.
- Firm Pressure: Apply firm, even pressure around all edges of the lid to secure it completely.
2. Stains or Odors
- Baking Soda Paste: For stubborn stains or odors, create a paste using baking soda and a small amount of water. Apply the paste to the affected area, let it sit for a few hours or overnight, then wash thoroughly.
- Vinegar Soak: Alternatively, soak the container in a solution of equal parts water and white vinegar for several hours, then wash as usual.
- Sunlight Exposure: Placing the clean, empty container in direct sunlight for a few hours can also help to neutralize odors.
