The invention discloses a plastic heat preservation utensil which comprises an inner plastic tube and an outer plastic tube. A vacuum interlayer is formed between the inner plastic tube and the outer plastic tube. Preferably, a one-way valve is arranged on the tube wall of the outer plastic tube, one port of the one-way valve is communicated with the vacuum interlayer, and the other port of the one-way valve is communicated with the external environment of the outer plastic tube; when air in the vacuum interlayer is pumped out through the one-way valve, the one-way valve is in the opening state. Due to the arrangement, the plastic heat preservation utensil is good in heat preservation performance and free of foam materials with toxin, and has the good environment-friendly effect. The invention further discloses a manufacturing method of the plastic heat preservation utensil.
Description
technical field [0001] The invention relates to the technical field of heat preservation vessels, in particular to a plastic heat preservation vessel and a processing method thereof. Background technique [0002] The plastic thermal insulation vessel in the prior art usually includes an inner tube and an outer tube, and a sandwich is formed between the inner tube and the outer tube. In the plastic heat preservation vessel in the prior art, the interlayer between the outer pipe and the inner pipe is filled with foam material or other heat preservation materials to achieve the effect of heat insulation. [0003] However, the heat preservation effect of the plastic heat preservation vessel in the prior art is still relatively poor. In addition, the foam material is used as the heat insulation layer of the heat preservation vessel, and the foam material contains toxins, which poses a safety hazard to human health. [0004] Therefore, how to solve the problems of poor thermal i...
