Ensuring Safe Nursing Environments for Babies During Disasters with Chu-bo Disposable Bottles

Introducing Chu-bo: Disposable Feeding Bottles for Emergencies

In an effort to enhance infant safety during disasters, Sagami Rubber Industries Inc. has introduced the revolutionary Chu-bo disposable feeding bottle. This innovative product has been implemented as disaster supplies in 159 municipalities across Japan's 47 prefectures. As of June 2025, these figures represent approximately 20% of the 792 municipalities in Japan.

Importance of Safe Nursing Environments

In the event of a disaster, securing a safe nursing environment for infants is essential. Evacuation centers often face limitations such as lack of electricity and running water, making the cleaning and sterilization of traditional bottles nearly impossible. Past disasters, including the Noto Peninsula Earthquake, highlighted the critical need for reliable nursing solutions when water and power supplies were disrupted for extended periods.

Given this backdrop, the Chu-bo bottle stands out as a disposable option that eliminates the need for sterilization. Parents can simply open the bottle and start feeding their babies right away, significantly reducing stress and logistical challenges for families and caregivers involved in emergency response efforts.

Feedback from Municipal Officials

Interviews with municipal officials have revealed positive sentiments surrounding the introduction of Chu-bo as disaster stock. One representative mentioned, “This initiative contributes to the peace of mind for families with infants. It’s easy to distribute, which has reduced the burden at the sites during emergencies.” These insights can be explored in detail on Sagami Rubber’s official note.

Unique Features of Chu-bo

The Chu-bo disposable bottle comes equipped with several standout features:

1. No Sterilization Required: Babies can be fed immediately after opening the bottle.
2. Disaster Preparedness: The bottles can be stored for extended periods and provide peace of mind during times of water or power outages.
3. Portability: Being lightweight and compact, the bottles fit easily in emergency bags.
4. Safe Materials: Constructed with BPA-free materials, ensuring safety for infants.
5. Compatibility: Works well with various types of milk, including powder and liquid.
6. Hygienic Design: Comes with a nipple cover for safe storage before and after use.

8. Measurement Markings: Clearly visible measurements for easy milk preparation.
9. Flexible Design: The bottle design allows for angle adjustments based on the baby's feeding position.

Sagami Rubber Industries plans to continue collaborating with municipalities and various medical and childcare organizations to further enhance efforts in protecting infants during emergencies. The company is dedicated to raising awareness about the Chu-bo bottle as an essential item for family emergency preparedness.
