Foldable Silicone Ice Ball Mold & Water Bottle – BPA-Free Travel Cup

2-in-1 Foldable Silicone Ice Ball Cup & Travel Water Bottle

Meet the ultimate on-the-go drinkware hack: a food-grade silicone cup that doubles as an ice ball mold and a portable water bottle. Fill it, freeze it, pop out a perfect round ice ball, then flip it into drinking mode — all in one compact, collapsible vessel. When you're done, fold it down to just 1/3 of its full size and tuck it into any pocket or pack. Perfect for camping, hiking, travel, home bars, or everyday hydration.

How to Make Ice Balls (Core Function)

1. Assembly: Securely snap the transparent lid onto the cup body, ensuring a tight seal at the connection to prevent leakage.
2. Add Water: Open the lid and pour clean water up to the MAX fill line (reserve 10–20% expansion space). Add fruit slices, mint leaves, or herbs for flavored ice.
3. Freeze: Close the lid tightly, lay the cup flat in the freezer, and freeze for 6–8 hours until fully solid.
4. Release Ice: Gently twist the lid or push the ice ball up from the base — the ball pops out cleanly without touching it with your hands. If it sticks, run a little warm water over the outside for 10 seconds.

How to Use as a Drinking Cup (2-in-1 Switch)

• After Making Ice: Open the lid, add your iced drink, juice, or coffee, insert the built-in straw, and enjoy.
• Standard Water Bottle Mode: Fill to your desired level, seal the lid tightly, and carry it leak-proof anywhere.
• Fold for Storage: Empty the cup, fully compress the body, and stow it away — it collapses to 1/3 of its original volume.

Usage Notes & Warnings

1. No Boiling Water: Silicone is rated to 120°C — do NOT pour boiling water directly into the cup.
2. Leak Check: After filling, invert the sealed cup briefly to confirm it's leak-proof before packing.
3. Flat Freezing: Always lay the cup flat in the freezer for an evenly shaped ice ball.
4. Avoid Sharp Objects: Store away from sharp items that could scratch or puncture the silicone.

Cleaning & Maintenance

1. Routine Cleaning: Rinse with warm water and mild dish soap; use a soft brush to clean any crevices. Dishwasher-safe (top rack, low-temperature mode).
2. First Use / Odor Removal: Soak in baking soda water or lemon juice for 30 minutes, then rinse thoroughly.
3. Monthly Disinfection: Submerge in boiling water for 5–10 minutes to keep it hygienic and extend its lifespan.
4. Long-Term Storage: Clean, fully dry, then fold before storing to prevent mildew.

Frequently Asked Questions

Q: Is the foldable silicone ice ball cup truly BPA-free and safe for daily use?

A: Yes — the cup is made from food-grade silicone that contains no BPA, lead, or other high-concern chemicals. It is rated safe across a wide temperature range (-40°C to 120°C), making it suitable for freezing as an ice mold, holding cold beverages, and even warm (not boiling) drinks. The material is also reusable and environmentally friendly.

Q: How long does it take to make an ice ball in this silicone cup?

A: Freeze time is approximately 6–8 hours. For best results, fill to the MAX fill line (leaving 10–20% expansion space), seal the lid tightly, and place the cup flat in the freezer overnight. You can also add fruit slices or mint leaves before freezing for a flavored ice ball.

Q: How small does the foldable water bottle compress for travel?

A: Once emptied, the flexible silicone body can be fully compressed down to roughly 1/3 of its original volume. This makes it incredibly easy to slip into a jacket pocket, backpack side pouch, or hiking pack without taking up noticeable space.

Q: Can I put this silicone travel cup in the dishwasher?

A: Yes — it is dishwasher-safe. Place it on the top rack only, and use a low-temperature wash cycle. For everyday cleaning, hand washing with warm water and a mild detergent (plus a soft brush for the folds) is recommended to maintain the cup's longevity.

Q: What should I do if the ice ball won't come out of the cup?

A: Simply run a small amount of warm (not hot) water over the outside of the cup and let it sit for about 10 seconds. The slight warming will loosen the ice ball so it pops out easily. Avoid pulling forcefully to prevent any stress on the silicone.
