Description

Double-opening insulation cup and manufacturing method thereof

The invention relates to a heat insulating cup and a manufacturing method thereof, and particularly relates to a heat insulating cup with a bilateral opening and a manufacturing method thereof.

Thermos bottles are based on the ability to maintain the temperature of their contents (such as cold or hot drinks) for a long time, and are therefore widely loved by the public. The thermal insulation principle of the thermos cup is generally vacuum isolation to reduce the temperature change of the contents.

The conventional thermos is usually composed of a stainless steel or ceramic shell, plus an inner tank that can hold water. In order to form a vacuum state between the casing and the liner, a common practice is to provide an opening at the bottom of the casing that is generally not easy to find, and use this opening to evacuate the casing and the liner. After the vacuum is evacuated, the opening is sealed to prevent the vacuum from being destroyed.

However, for more applications, some practitioners have conventionally designed bottles with single-sided openings as double-sided opening designs. However, the design of the double-sided opening will not be easy to evacuate, so the double-open bottles on the market currently have no thermal insulation effect.
