Abstract

The invention relates to a plastic bowl cover with good heat preservation effect. The plastic bowl cover comprises a cover body and a handle, wherein the handle is connected with the top of the coverbody by virtue of a supporting rod, the cover body protrudes upward externally, the middle part of the cover body is sunken downward to form a pit, the handle is arranged at the bottom of the pit, anda heat preservation supporting piece capable of heating continuously covers the handle; and the top surface of the heat preservation supporting piece is a supporting surface, and a locating slot fitting the handle in shape is formed in the bottom of the heat preservation supporting piece, and sheathes the handle. The plastic bowl cover provided by the invention has the advantages that the pit isformed in the middle part of the cover body, and the top of the handle is lower than the cover body, so that the cover body can be used as a mat for holding a cooking utensil; the heat preservation supporting piece can provide appropriate heat for food in a plastic bowl, so that better heat preservation effect is achieved, and food cooling rate is reduced; meanwhile, the plastic bowel cover lookslike the top of an apple, so that the plastic bowl cover with good heat preservation effect looks more beautiful, so as to achieve decorative effect of the plastic bowl.

Example Embodiment

[0012] Example 1
[0013] Such as figure 1 As shown, the plastic bowl cover with good heat preservation effect in this embodiment includes a cover body 4 and a handle 2. The handle is connected to the top of the cover body 4 through a support rod. The outer part 1 of the cover body 4 protrudes upward, and the cover body The middle part is recessed downward to form a pit 3, the handle 2 is installed at the bottom of the pit 3, and the handle is covered with a heat-preserving support 6 that can continue to generate heat; the top surface of the heat-preserving support 6 is a support surface, so The bottom of the heat-preserving support 6 is provided with a positioning groove corresponding to the shape of the handle, and the positioning groove of the heat-preserving support 6 is sleeved on the handle.
[0014] The heat preservation support 6 has an inner cavity, and the inner cavity of the heat preservation support 6 contains a phase change material with a phase change temperature of 85 degrees. Phase Change Material (PCM-Phase Change Material) refers to a substance that changes the state of a substance with temperature changes and can provide latent heat. The process of changing physical properties is called the phase change process. At this time, the phase change material will absorb or release a large amount of latent heat. Once this material is widely used in human life, it will become the best green carrier for energy conservation and environmental protection, and it has been listed as a national R&D and utilization sequence in my country. Choosing a phase change material of 85 degrees can provide suitable heat to the food in the plastic bowl, play a better role in heat preservation, and delay the cooling speed of the food.
[0015] The height of the top of the handle 2 is equal to the height of the cover 4.
[0016] Such as figure 1 As shown, when the plastic bowl is filled with freshly cooked food and needs to be placed on the table, first put the plastic bowl cover with good heat preservation effect on the table, and then put the plastic bowl on the plastic with good heat preservation effect The top surface of the heat preservation support 6 of the bowl cover.

Example Embodiment

[0017] Example 2
[0018] The difference between the plastic bowl cover with good heat preservation effect in this embodiment and embodiment 1 is:
[0019] The heat preservation support 6 is an electric heating device.
[0020] The handle 2 is completely located in the pit, and the height of the top of the handle 2 is smaller than the height of the cover 4.
