This multi-functional design is the core of the product, which is a back milk bag and a double-layer bento bag. It has the function of keeping breast milk warm and fresh. It is a storage bag and also an ice pack. Through the combination of structure and material, it meets the needs of mother and baby groups for storing breast milk, carrying meals, and other multiple scenarios, balancing practicality and professionalism.

The multifunctional design is reflected in the flexible adaptation of the scene. As a back milk bag, it can store mother and baby products such as breast pumps, milk storage bags, and bottles; As a double-layer bento bag, it can store breast milk and complementary foods separately; As a storage bag, it enables the zoning and organization of items; As an ice pack, it provides a low-temperature preservation environment, and the multi-functional feature of one pack improves usage efficiency and reduces carrying burden.

The double-layer structure is the basis for functional implementation, with a height of 15cm in the upper space. It is equipped with independent bottle fixing positions (with elastic bands) and milk storage bag grid inserts (capable of accommodating 8-10 milk storage bags) to avoid collisions between breast milk containers; The lower space has a height of 12cm and can accommodate 2 standard complementary food boxes. The double layers are separated by thermal insulation partitions to prevent temperature interference and meet the separate storage needs of breast milk and complementary food.

The insulation and preservation function of breast milk relies on a professional temperature control system. The inner layer is made of food grade thickened aluminum foil (thickness 0.15mm), combined with 5mm high-density pearl cotton in the middle, and the outer layer is made of 600D Oxford cloth, forming a three-layer insulation structure. Tests have shown that in an environment of 25 ℃, without an ice pack, it can be kept warm for 4-6 hours (maintaining a temperature of 2-4 ℃). After placing the ice pack, the cooling time can be extended to 12-16 hours, which meets the temperature requirements for breast milk storage, delays bacterial growth, and ensures the freshness of breast milk.

The storage function is achieved through fine zoning, with a zipper bag (size 18cm × 12cm × 4cm) located on the front side of the main compartment, which can hold breast pump accessories and disinfectant wipes; Elastic mesh bags are installed on both sides to accommodate ice packs and water bottles respectively; The hidden pocket on the back can store documents, and each area is independently enclosed to avoid mixing of items and odor interference, improving the convenience of access.

As an ice pack, it has outstanding low-temperature retention ability, and the surface of the fabric has been treated with anti splash water, making it difficult for condensed water in the ice pack to penetrate to the outside, protecting surrounding items from drying. The bag body adopts a sealed zipper design, which has good air tightness after closure, reducing the loss of cold energy. It is suitable for storing temperature sensitive items such as breast milk and complementary foods, and can maintain low internal temperature even in high temperature environments.

The material selection takes into account both safety and durability. The outer layer of Oxford cloth has a tear resistance strength of 90N, which can withstand friction and compression during daily use; The inner aluminum foil has passed the food contact test, and the lead and cadmium content are both less than 0.01mg/kg, which meets the relevant FDA standards; The insulation partition is made of food grade EVA material, which has no odor and ensures the safe storage of breast milk and complementary foods.

Detail design enhances professional attributes, with a shoulder strap width of 5cm filled with pressure reducing sponge, adjustable length (70-130cm), comfortable for both shoulders or crossbody carrying; Bottom anti slip foot pad, not easy to slide when placed; The zipper is selected as a waterproof model, with a pulling resistance of ≤ 2N. After closure, the chain head automatically locks to ensure sealing. The overall design is simple, with gray, black, and navy blue as the main colors, suitable for different occasions without appearing abrupt.
