[0033] Step 2, said transparent raw material is melted by heating through said injection molding machine and then injected into said first mold to obtain the upper transparent shell 1, as shown in FIG. 3, the thickness of the upper transparent shell 1 needs to be greater than 1 mm and is usually controlled to be less than 5 mm, and the upper transparent shell 1 has verge 10 extending outwardly from the bowl body. [0034] cooling said upper transparent shell 1 in said first shaping mold having the same contour as said upper transparent shell 1, in order to reduce deformation and errors resulting from shrinkage, and in order to achieve a better shaping effect, a first injection mold having dimensions identical to those of the cavity 12 in which said upper transparent shell 1 is shaped may be used. In order to achieve a better shaping effect, a first shaping mold with dimensions consistent with the cavity 12 of the first injection mold for molding the upper transparent shell 1 can be used.

[0035] Step 3: fixing said upper transparent shell 1 inversely to said printing machine, exposing the bottom, and printing the desired pattern on the bottom of said upper transparent shell 1 using said high temperature resistant ink to obtain a pattern layer 2, as shown in FIG. 3.

[0036] In this step, the heat resistant temperature of said heat resistant ink used needs to be greater than 160 degrees Celsius so that said heat resistant ink is not thermally decomposed when injecting the silicone.

[0037] The way of printing the pattern layer 2 can be silk screen printing or heat transfer printing, etc.

[0038] Step 4, at the bottom of said upper transparent shell 1 there is printed a separation layer 3 covering said pattern layer 2, as shown in FIG. 3; the separation layer 3 helps to enhance the color effect of the pattern layer 2, and the color of the printed pattern layer 2 will not be affected by the color of the underlying structure. the color of the printed pattern layer 2 will not be affected by the color of the underlying structure.

[0039] Step 5, placing said upper transparent shell 1 printed with said pattern layer 2 and said separation layer 3 in said second mold, injecting said soft plastic into said second mold after melting by heating in said injection molding machine to form a soft plastic layer 4, as shown in FIG. 3, said soft plastic layer 4 encapsulating said separation layer 3.

[0041] The color of said soft plastic can be adjusted according to the design requirements of the product, and different colors of soft plastic layer 4 can be obtained by adding different colors of color powder or pigment to the soft plastic during injection molding.

[0042] The meal bowl obtained by S5 is placed to cool in said second shaping mold having the same contour as said meal bowl, in order to reduce the deformation and error resulting from shrinkage.

[0043] As shown in FIGS. 1 to 4, a meal bowl, made by the above production process of the meal bowl, comprises an upper transparent shell 1 made by injection molding; the thickness of the upper transparent shell 1 needs to be greater than 1 mm, and is usually controlled to be less than 5 mm, and in this embodiment, the thickness of the upper transparent shell 1 is in this embodiment, the thickness of the upper transparent shell 1 is 1.5 mm.

[0044] The upper transparent shell 1 has a verge 10 extending outwardly from the body of the bowl, with a protruding platform 11 extending downwardly around the outer periphery of said verge 10; said protruding platform 11 forming a cavity 12.

[0045] The transparent raw material for making said upper transparent shell 1 is PP, Ttritan or other food-grade highly translucent material having a light transmittance of more than 95% and a heat-resistant temperature of more than 100 degrees Celsius.

[0046] Printing of a pattern layer 2 on the bottom surface of said upper transparent shell 1, the printing method being either screen printing or heat transfer printing. The ink for printing the pattern layer 2 needs to be a high temperature resistant ink, said high temperature resistant ink needs to have a heat resistance temperature greater than 160 degrees Celsius so that said high temperature resistant ink is not subjected to thermal decomposition when injection molding silicone or other soft gels.

[0047] On the bottom surface of said upper transparent shell 1 is printed a separation layer 3 covering said pattern layer 2, the separation layer 3 is preferably a separation layer 3 printed in white color, the separation layer 3 helps to enhance the color effect of the pattern layer 2, so that the printed pattern layer 2 has a better color effect. layer's color effect, so that the printed pattern layer 2 reveals a color that is not affected by the color of the underlying structure, and the color of the separation layer 3 is not limited to white, but can highlight both the pattern and the color of the pattern layer 2.

[0048] Finally, soft plastic is injected at the bottom of the upper transparent shell 1, the covering range of the soft plastic is smaller than the verge 10 of said upper transparent shell 1, and at the same time, the soft plastic is filled with said cavity 12 to form a soft plastic layer 4, resulting in a meal bowl. the cavity 12 can facilitate the combination of the soft plastic layer 4 and the upper transparent shell 1, and the soft plastic layer 4 is flush with the protruding platform 11 after filling the cavity 12. The cavity 12 can facilitate the combination of the soft plastic layer 4 and the upper transparent shell 1, and the soft plastic is flush with the protruding platform 11 after filling the cavity 12, so that the hand feeling is good when picking up.

[0049] Further, suction pad 13 may also be provided at the bottom of said soft plastic layer 4, and suction pad 13 may be injected together with the soft plastic layer 4 during injection molding, or suction pad 13 may be injected or bonded again after injection molding of the soft plastic layer 4.

[0050] In this embodiment, said soft plastic is food-grade TPE or silicone; said soft plastic has a heat-resistant temperature greater than 100 degrees Celsius; and said soft plastic has a Shore hardness of less than 80 degrees.

[0051] In this embodiment, the upper transparent shell 1 is first injection molded, and then the desired pattern is printed on the bottom of said upper transparent shell 1 with high temperature resistant ink, where the pattern can be any pattern that babies and young children like; the setting of a separation layer 3 helps to enhance the color of the pattern layer 2 The color of the printed pattern layer 2 will not be affected by the color of the underlying structure; the injection molded soft rubber covers the entire bottom of the upper transparent shell 1, and closes the pattern layer 2 and the separation layer 3.

[0052] Through the above scheme, the bowls are made of upper transparent shell 1, pattern layer 2, separation layer 3 and soft plastic layer 4 from top to bottom, and the patterns that babies and children like can be clearly shown through the upper transparent shell 1 with the separation layer 3 as the background, while the bowls in contact with food are always made of upper transparent shell 1. The pattern that babies and children like can be clearly shown through the upper transparent shell 1, while the food contact is always with the upper transparent shell 1. The existence of the upper transparent shell 1 eliminates the harm to babies and children caused by heavy metals in industrial coloring, ink or glaze that may be present in the bowls produced by traditional methods, so the risk of food safety is low; at the same time, the product is made of food-grade plastic. The product is made of food-grade plastic, which is sturdy and lightweight, and the soft plastic layer 4 provides an effective anti-slip effect, which is good for food preparation and use by infants.
