Description

TECHNICAL FIELD OF THE INVENTION

[0001] The present invention relates to the technical field of tableware, and more particularly, to a child's self-adapting meal plate capable of preventing a child from picking up, turning over or throwing the meal plate away.

BACKGROUND OF THE INVENTION

[0002] Children are naturally inclined to play while eating on a meal plate. For example, they frequently pick the meal plate up, turn it over, and throw it away, spilling food on the table or on the floor, greatly frustrating their parents. The wasted food can pollute the environment, further burdening their parents.

SUMMARY OF THE INVENTION

[0003] The purpose of the present invention is to overcome the shortcomings in the prior art and provide a child's self-adapting meal plate, which can prevent a child from picking up, turning over or throwing the meal plate away.

[0004] To achieve the above purpose, the present invention adopts the following technical solution:

[0005] A child's self-adapting meal plate comprises 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. 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.

[0006] In another preferred embodiment, 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. A piston having an I-shaped cross section is disposed in the through-hole, which can move upward and downward within the through-hole. The lower extension edge of the piston is provided with at least one channel that connects the vacuum chamber and the through-hole. 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 a lowest position, the upper opening of the through-hole is tightly pressed by the piston, enabling the vacuum chamber to be sealed.

[0007] In another embodiment, the channel can be a plurality of small holes provided at the lower extension edge of the piston.

[0008] In another embodiment, 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.

[0009] In another embodiment, the flange portion extends outward from the base of the soft gel plate body, and a gap is existed between the flange portion and the base of the soft gel plate body.

[0010] In another preferred embodiment, the outer edges of the flange portion are on the same plane.

[0011] In another preferred embodiment, the upper surface of the soft gel plate body extends upward to form three annular protruding portions, thereby forming an accommodating chamber.

[0012] In another preferred embodiment, the soft gel plate body and the piston are made from silica gel.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] The bottom edge of the soft gel plate body of the present invention extends downward to form a vacuum chamber. Consequently, when the piston moves downward to the second position at the usual time, the upper opening of the through-hole is tightly pressed by the piston, enabling the vacuum chamber to be sealed. When a meal plate is placed on the table or on the floor, the air in the vacuum chamber can be squeezed out under the weight of the food in the soft gel plate body. Thus, it's difficult for a child to pick the meal plate up because the pressure in the vacuum chamber of the bottom surface of the soft gel plate body is lower than the atmospheric pressure, effectively preventing a child from picking up, turning over or throwing the meal plate away. Once an adult needs to move the meal plate, the piston can be moved upward, enabling the external air to flow into the vacuum chamber through the through-hole and the channel. Thus, the meal plate can be easily taken away.

DETAILED DESCRIPTION OF THE INVENTION

[0019] Drawings and detailed embodiments are combined hereinafter to elaborate the technical principles of the present invention.

[0020] As shown in FIGS. 1-3, the child's self-adapting meal plate comprises a soft gel plate body 10. The upper surface of the soft gel plate body 10 extends upward to form at least one annular protruding portion, thereby forming an accommodating chamber 5. The bottom edge of the soft gel plate body 10 extends downward to form a vacuum chamber 4. The soft gel plate body 10 is provided with a through-hole 2, which has an I-shaped cross section and is connected to the vacuum chamber 4. A piston 1 having an I-shaped cross section is disposed in the through-hole 2, which can move upward and downward within the through-hole 2. The lower extension edge of the piston 1 is provide with at least one channel 3 that connects the vacuum chamber 4 and the through-hole 2. When the piston 1 moves upward, the vacuum chamber 4 is connected to the exterior through the channel 3 and the through-hole 2, and when the piston 1 moves downward to a lowest position, the upper opening of the through-hole 2 is tightly pressed by the piston 1, enabling the vacuum chamber 4 to be sealed. In some embodiments, the vacuum chamber 4 can be a T-shaped chamber or a straight hole, and the piston can be other shapes having one end provided with an extension sealing edge, which can achieve the same sealing effect.

[0021] The bottom edge of the soft gel plate body 10 of the present invention extends downward to form a vacuum chamber 4. Consequently, when the piston 1 moves downward to the extreme position at the usual time, the upper opening of the through-hole 2 can be tightly pressed by the piston 1, enabling the vacuum chamber 4 to be sealed. When a meal plate is placed on the table or on the floor, the air in the vacuum chamber 4 can be squeezed out under the action of the self-weight of the food in the soft gel plate body 10. It's difficult for a child to pick up the meal plate because the pressure in the vacuum chamber 4 of the bottom surface of the soft gel plate body is lower than the atmospheric pressure, which can prevent a child from picking up, turning over or throwing the meal plate away. Once an adult needs to move the meal plate, the piston 1 can be moved upward, enabling the external air to flow into the vacuum chamber 4 through the through-hole 2 and the channel 3. Thus, the meal plate can be easily taken away.

[0022] As shown in FIGS. 2 and 3, in one embodiment of the child's self-adapting meal plate of the present invention, the channel 3 can be a plurality of small holes provided at the lower extension edge of the piston 1.

[0023] As shown in FIGS. 2 and 3, in another embodiment of the child's self-adapting meal plate of the present invention, in order to reinforce the sealing performance after the meal plate is placed, the lower surface of the soft gel plate body 10 extends downward to form a flange portion 7, and a vacuum chamber 4 is formed within the flange portion 7. When the meal plate is slightly deformed or the table top is not very smooth, the flange portion 7 can self-adapt to the uneven surface while ensuring the sealing effect.

[0024] In another embodiment of the child's self-adapting meal plate of the present invention, as shown in FIGS. 2 and 3, the flange portion 7 extends outward from the base of the soft gel plate body 10, and a gap 6 is disposed between the flange portion 7 and the base of the soft gel plate body 10.

[0025] In another embodiment of the child's self-adapting meal plate of the present invention, as shown in FIGS. 2 and 3, in order to improve the fixity after the meal plate is placed, the outer edges of the flange portion 7 are on the same plane.

[0026] In another embodiment of the child's self-adapting meal plate of the present invention, as shown in FIG. 1, the upper surface of the soft gel plate body 10 extends upward to form three annular protruding portions, thereby forming an accommodating chamber 5.

[0027] In another embodiment of the child's self-adapting meal plate of the present invention, the soft gel plate body 10 and the piston 1 are made from silica gel.

[0028] In another embodiment, the under surface of the child's self-adapting meal plate comprises a flange portion 7, a through hole portion 3, and a vacuum chamber 4, wherein the bottom surface of the vacuum chamber 4 and the bottom surface of the flange portion 7, and the bottom surface of the piston 2 create three separate sealable contact surfaces.

[0029] The previous descriptions are of preferred examples for implementing the invention, and the scope of the invention should not necessarily be limited by this description. The scope of the present invention is defined by the claims.
