Self-adapting meal plate

Abstract

A child's self-adapting meal plate comprising a soft gel plate body; the upper surface of the soft gel plate body extends upward to form at least one annular protruding portion, thereby forming an accommodating chamber; the bottom edge of the soft gel plate body extends downward to form a vacuum chamber; the soft gel plate body is provided with a through-hole that is connected to the vacuum chamber 4; a piston is disposed in the through-hole, which can move upward and downward within the through-hole; when the piston moves to a first position within the through-hole, the vacuum chamber is connected to the exterior through the through-hole, and when the piston moves downward to a second position, the upper opening of the through-hole is tightly pressed by the piston, enabling the vacuum chamber to be sealed.

1 . A child's self-adapting meal plate, comprising:
 a soft gel plate body, wherein the upper surface of the soft gel plate body extends upward to form at least one annular protruding portion, thereby forming an accommodating chamber, wherein the bottom edge of the soft gel plate body extends downward to form a vacuum chamber, wherein the soft gel plate body is provided with a through-hole that is connected to the vacuum chamber, wherein a piston is disposed in the through-hole, which can move upward and downward within the through-hole, wherein when the piston moves to a first position within the through-hole, the vacuum chamber is connected to the exterior through the through-hole, and when the piston moves downward to a second position, the upper opening of the through-hole is tightly pressed by the piston, enabling the vacuum chamber to be sealed.   
     
     
         2 . The child's self-adapting meal plate of  claim 1 , wherein the soft gel plate body is provided with a through-hole, which has an I-shaped cross section and is connected to the vacuum chamber, wherein a piston having an I-shaped cross section is disposed in the through-hole, which can move upward and downward within the through-hole, wherein the lower extension edge of the piston is provided with at least one channel that connects the vacuum chamber and the through-hole, wherein when the piston moves upward, the vacuum chamber is connected to the exterior through the channel and the through-hole, and when the piston moves downward to an extreme position, the upper opening of the through-hole is tightly pressed by the piston, enabling the vacuum chamber to be sealed. 
     
     
         3 . The child's self-adapting meal plate of  claim 2 , wherein the channel can be a plurality of small holes provided at the lower extension edge of the piston. 
     
     
         4 . The child's self-adapting meal plate of  claim 1 , wherein the lower surface of the soft gel plate body extends downward to form a flange portion, and a vacuum chamber is formed within the flange portion. 
     
     
         5 . The child's self-adapting meal plate of  claim 3 , wherein the flange portion extends outward from the base of the soft gel plate body, and a gap is disposed between the flange portion and the base of the soft gel plate body. 
     
     
         6 . The child's self-adapting meal plate of  claim 1 , wherein the outer edges of the flange portion are on the same plane. 
     
     
         7 . The child's self-adapting meal plate of  claim 1 , wherein the upper surface of the soft gel plate body extends upward to form three annular protruding portions, thereby forming an accommodating chamber. 
     
     
         8 . The child's self-adapting meal plate of  claim 1 , wherein the soft gel plate body and the piston are made from silica gel. 
     
     
         9 . The child's self-adapting meal plate of  claim 1 ,
