    • The present invention provides a baby food container and a handy spoon, both combined into one convenient unit. The food container itself basically resembles a tube of toothpaste, featuring a malleable plastic material. The food contained within the unit is of the standard baby food variety. Featuring a safety seal beneath the lid, the threaded opening serves as the attaching point of the provided spoon, a soft plastic utensil with a distinct oval shape. Additionally, a protective cap is provided to enclose the Baby Food Spoon system between uses. Simple in design yet effective in application, one need only choose a container of food, remove the safety seal, and twist on the spoon attachment. Squeezing the food container, the user is able to dispense desired amounts of food into the spoon, and feed the waiting baby.
    • 本发明提供一种婴儿食品容器和一个方便的勺子,两者组合成一个方便的单元。 食物容器本身基本上类似于一个牙膏管,具有可塑性塑料材料。 包含在单位内的食物是标准的婴儿食品。 在盖子下方有安全密封,螺纹开口用作提供的勺子的附着点,一个具有明显椭圆形的软塑料餐具。 此外,提供保护帽以在使用之间包围婴儿食品匙系统。 设计简单但有效的应用,只需选择一个食物容器,取下安全密封,并扭转勺子附件。 挤压食物容器,用户能够将所需量的食物分配到勺子中,并喂养等待的婴儿。
