Infant and toddler feeder

An infant and toddler feeder, comprising:

• a first main body;
• and
• a second main body;
• wherein
• the first main body has a food pouch and a filling opening;
• the food pouch comprises a biting and sucking area and a cylindrical temporary storage area;
• the filling opening is disposed at one end of the cylindrical temporary storage area, and the biting and sucking area is disposed at the other end of the cylindrical temporary storage area;
• the second main body has an opening sealing portion, a piston, and a pushing connection portion;
• the opening sealing portion is matched with the filling opening for connecting the filling opening and sealing the filling opening;
• the piston is matched with an inner cavity of the cylindrical temporary storage area to form a connection structure of the piston;
• the pushing connection portion is connected between the piston and the opening sealing portion;
• the pushing connection portion provides elastic thrust F, such that the piston has a movement trend towards the biting and sucking area;
• the pushing connection portion is a barrel-shaped thin-walled cone having a first end face and a second end face,
• the barrel-shaped thin-walled cone is elastic;
• the first end face is connected to the piston;
• the second end face is connected to the opening sealing portion;
• an area of the first end face is smaller than an area of the second end face;
• and
• when the first end face moves towards the second end face under the action of external force, the barrel-shaped thin-walled cone can elastically deform and form a nested structure.
