Insulation container construction

This creation relates to a construction of a heat-insulating container, and more particularly to an insulated container that does not release harmful substances due to high temperature, and which is less prone to fouling, odor residue, and bacterial growth.

Most of the container bodies of commercially available insulated containers are made of stainless steel, and the upper cover is made of plastic material, and a silicone sealing ring is used to seal the bottle mouth. However, when the thermal insulation structure is used for hot drinks, the upper cover may release harmful substances such as plasticizers due to high temperature, and the silicone seal ring may easily accumulate dirt, residual odor and bacteria, thereby affecting the health of the drinker. Therefore, in view of the shortcomings of the aforementioned insulated container, there is a patent of the "Cup Cover" of the Republic of China Patent No. M417340, which discloses a body comprising a body, a core column and a stainless steel protective layer, the body having an opening space facing downward. The stem extends downward from the inner top surface of the body, and a gap is formed between the side of the stem and the inner side of the body, and the stainless steel protective layer covers the lower end of the stem; therefore, the stainless steel is The protective layer is exposed to the outermost side for contact with high temperature liquids or vapors without releasing harmful substances. However, the cup cover of the previous case still uses the seal ring, and neglects that the use of the seal ring easily causes the insulation container to release harmful substances, accumulate dirt, residual odor and bacteria.

Accordingly, in order to improve the lack of the prior art, the present invention provides an insulated container structure comprising an upper cover and a container body, the upper cover including a first metal sealing surface, and the aforementioned container The main body includes a second metal sealing surface. When the upper cover is coupled to the container body, the first metal sealing surface is corresponding to the second metal sealing surface.

The heat preservation container is a thermos flask or a heat preservation cup, and the upper cover is screwed to the container body.

The container body has a hollow insulating layer.

The upper cover includes an upper cover body and a core body, the core body is provided with the first metal sealing surface, the first metal sealing surface is located inside the upper cover body, and corresponds to the second body of the container body Metal sealing surface.

The upper cover includes an upper cover body and a core body, the core body is provided with the first metal sealing surface, the first metal sealing surface is located outside the upper cover body, and corresponds to the second metal seal of the container body Face.

The first metal sealing surface and the second metal sealing surface are one of an inclined surface, a curved surface, a flat surface, or a combination thereof.

The first metal sealing surface and the second metal sealing surface respectively have inclined surfaces having the same inclination angle.

The first metal sealing surface and the second metal sealing surface respectively have curved surfaces having the same curvature.

The first metal sealing surface and the second metal sealing surface have the same area.

The areas of the first metal sealing surface and the second metal sealing surface are different.

The pressing area of the first metal sealing surface and the second metal sealing surface is equal to the area of the first metal sealing surface and the second metal sealing surface.

The pressing area of the first metal sealing surface and the second metal sealing surface is smaller than the area of the first metal sealing surface and the second metal sealing surface.

The effect of this creation:

1. All metal storage space, effectively solve the problem that the existing insulated container will release harmful substances.

2. The sealing ring is replaced by a metal sealing surface to prevent liquid leakage, which can solve the problems of scale ringing, odor residue and bacterial growth of the sealing ring.
