  • Patent number: 4796758
    Abstract: An improved portable case is provided to enable the chilling, storing and transportation of expressed human milk. The portable case includes several components, a durable and rugged case, an insulated chest, storage bottles and chilling means. The case has upper and lower compartments, wherein the upper compartment may be used to store a breast pump or a similar device. The lower compartment houses the insulated chest. Within the insulated chest are three sturdy and unbreakable storage bottles. The expressed milk is discharged into the storage bottles, which are chilled by coolant gel packs. Two of the three storage bottles are sandwiched upright between the coolant gel packs, which conform to the sides of the storage bottles, allowing uniform and maximum surface area chilling. The third storage bottle is perpendicularly placed adjacent to the other storage bottles, enabling the user to place and chill an eight ounce (8 oz.) beverage container atop the third storage bottle.
