Description

Multi-layer thermal insulation container

The present invention relates to a heat preservation container, in particular to a multi-layer heat preservation container which can be used for keeping cold or holding liquid.

Insulation containers usually use a vacuum sandwich as a thermal insulation structure. In order to form a vacuum interlayer, the material of the thermal insulation container must be hard enough to withstand deformation caused by the pressure difference formed by the vacuum interlayer. A common material is stainless steel. Stainless steel is easy to make vacuum interlayer, and it has the advantage of being resistant to impact and not easy to break.

However, stainless steel is not acid-resistant, and the liquid contained in the insulated container is often an acidic liquid with strong acidity, such as fruit juice. Acidic liquids will slowly corrode stainless steel, causing some metals in the stainless steel to ionize and dissolve into the liquid contained in the insulated container. Under long-term use, it is easy to cause corrosion or qualitative change because it contains a variety of drinks, which is harmful to human health and unsafe.

Glass containers are relatively acid-resistant, but glass is fragile and not portable. At the same time, glass materials are not suitable for hot drinks, otherwise there will be problems of heavy metal precipitation.

In order to solve the above problems, the prior art uses a coating process to make a ceramic coating on the inner layer of the thermal insulation container to isolate the thermal insulation container body and the liquid contained therein. However, the processing cost of the coating process is high, and the thickness of the ceramic coating is also limited. Low-thickness ceramic coatings will be gradually worn out during cleaning or use, and they will partially fall off, leaving the material of the thermal insulation container exposed and losing the protective effect. If the thickness of the ceramic coating is increased, the processing cost will be greatly increased, and the thickness will be limited.

In view of the above problems, the present invention proposes a multi-layer thermal insulation container, which includes a heat insulator, an inner cup, a sealing ring, and an upper lid. The heat insulator has an outer cylinder and an inner cylinder. The outer cylinder covers the outside of the inner cylinder, and a vacuum sandwich is formed between the inner cylinder and the outer cylinder. The heat insulator further has an open end. And a bottom end respectively corresponds to the two ends of the inner cylinder and the outer cylinder. The inner cup body has a cup mouth and a bottom, and the inner cup body is arranged in the inner cylinder so that the cup mouth corresponds to the open end. The sealing ring is located on the inner edge of the open end to seal the gap between the cup mouth and the open end. The upper cover is detachably combined with the heat insulation member, and closes the open end and the cup mouth.

In at least one embodiment, the multi-layer thermal insulation container further comprises a foam material filled between the inner cylinder and the inner cup.

In at least one embodiment, the bottom end of the heat insulation member is open, and the multi-layered heat insulation container further includes a bottom cover, which is detachably coupled to the heat insulation member and closes the bottom end.

In at least one embodiment, the bottom cover is screwed to the bottom end.

In at least one embodiment, the heat-insulating member further includes an inner flange extending from the edge of the open end inward in a radial direction, and the mouth of the inner cup body abuts against the inner flange.

In at least one embodiment, the sealing ring is clamped between the cup mouth and the bottom surface of the inner flange.

In at least one embodiment, the material of the inner cup body is ceramic.

In at least one embodiment, the upper cover has at least one foldable handle and is pivotally disposed on a top surface of the upper cover.

In at least one embodiment, the upper cover has at least one ventilation hole.

In at least one embodiment, a ring-shaped groove is provided on a top surface of the upper cover, and the upper cover further includes a flexible ring. A part of the flexible ring is fixed on the top surface, and the rest is detachably filled in the ring-shaped groove. .

In at least one embodiment, the upper cover has a base and a flip cover, the base is detachably coupled to the open end of the heat insulation member, and the base has a through hole communicating with the open end. To close the through hole.

Through the combination of the heat insulation member and the inner cup body, the novel material can make the material inside the layer heat-insulating container easier to arrange the inner layer material with a sufficient thickness, without having to go through a relatively low-yield and high-cost coating process. The inner cup body as the inner layer material can be increased in thickness as required, so that the inner cup body is more resistant to abrasion, so the performance of life is better than that of the coating.
