Grosmimi x Knotted PPSU Straw Cup pairs Grosmimi's PPSU straw-cup system with four Knotted character designs: Smile, Cream Bunny, Dough Puppy, and Sugar Bear. The cup includes a Step 1 silicone straw teat, a regular straight straw tube, a one-touch cap, and a rotating two-handle grip. It is intended for babies from 6 months old using the included Step 1 straw teat.
Key Features
- Anti-leak '+' cut straw: the cross-cut opening and air-valve system are designed to release liquid while the child drinks and reduce leaking or backflow.
- Two-way use: use the straw teat without the internal tube for a child drinking while reclined, then connect the regular tube when the child can sit and drink upright.
- One-touch cap: flip-top cap with a button closure for convenient opening and closing.
- Easy grip: the 360° rotating handles can be held from different directions.
- Stable shape: a slim body and wide base are designed for comfortable gripping and stability during use or drying.
PPSU Material
The bottle body is made from PPSU, a lightweight, durable, heat-resistant material used for products that undergo repeated sterilization. Grosmimi's product materials also report commissioned safety testing of the PPSU body and state that no detectable microplastics were found in the referenced test. The bottle body is rated to 200°C. No cold-resistance temperature is stated in the reviewed series specifications.

Grosmimi's selection guide recommends the shorter 200ml cup for first-time users, weaning water, or smaller portions. The 300ml cup is recommended as drinking volume increases or for milk and juice.
Materials and Included Components
- Bottle body: PPSU, heat resistance 200°C.
- Handle: PP, heat resistance 100°C; 360° rotating two-handle grip.
- Straw teat and tube: silicone rubber, heat resistance 180°C. A soft Step 1 straw teat and regular straight straw tube are included.
- Cap and other parts: PP and silicone rubber, heat resistance 100°C.
- No weighted straw: this Knotted configuration includes a regular straight straw tube, not a weighted straw or weighted straw kit.
The firmer Step 2 replacement straw teat is sold separately and is recommended by Grosmimi for children over 12 months who actively chew the straw.
How to Use
- Wash, sterilize, and fully dry every part before first use.
- For reclined drinking, use the straw teat without the internal tube. For upright drinking, connect the regular straw tube.
- Assemble the straw teat securely and check the inner '+' slit before every use.
- For hot beverages above 40°C or carbonated drinks, pressure can cause backflow. Tighten the neck ring slowly and pinch the air valve two or three times to release air before use.
Cleaning and Sterilization
Disassemble the cup completely. Use a soft sponge or a dedicated straw brush. Insert the brush only to the illustrated depth and rotate it side to side; pushing it too far can damage the '+' cut and cause leakage.
| Method | PPSU Bottle | Straw Teat / Tube | Handle | One-Touch Cap |
|---|---|---|---|---|
| UV sterilizer | Yes | Yes | Yes | Yes |
| Hot-water sterilization | Under 5 minutes | Under 30 seconds | Under 30 seconds | No |
| Dishwasher | Yes | Yes | Yes | No |
| Steam sterilizer | Yes | Yes | No | No |
| Microwave sterilization | Within 1 minute in a microwave-safe sterilization container filled with at least 2/3 water | Sterilize by soaking in water in the approved container | No | No |
Do not microwave the assembled cup, and never put the one-touch cap in a microwave. Turn off the heat before placing parts in hot water. Prolonged UV exposure may fade or weaken parts. Dishwasher friction can damage the product or peel printed designs.
Care and Safety
- Do not leave beverages in the cup for extended periods. Separate all parts and air-dry after use.
- Replace the silicone straw teat and tube every 2–3 months, or immediately if suction weakens or damage appears. Grosmimi recommends replacing the PPSU bottle body every 6–12 months; actual timing depends on use and cleaning.
- Read the user manual and safety instructions before use. Keep away from fire and direct sunlight.
- Do not use the straw teat as a pacifier, and do not allow parts other than the straw teat to contact the child's mouth.
- Do not drop or strongly impact the product. Printed designs may wear with use, and component colors may vary slightly by production period.
- Do not close the lid immediately after filling with a hot drink. Internal pressure may cause overflow.
- The cup is not completely sealed. Carry it upright in a separate pouch.
