Description
Technical Field
The present invention relates to a vacuum cup and a manufacturing method thereof, and more particularly, to a vacuum cup with two openings and a manufacturing method thereof.
Background
Vacuum cups (thermal cups) are widely popular because they maintain the temperature of their contents (e.g., cold or hot beverages) for extended periods of time. The heat preservation principle of the vacuum cup is generally in a vacuum isolation mode so as to reduce the temperature change of the contents.
The existing vacuum cup is generally composed of a shell made of stainless steel or ceramic materials and an inner container capable of containing water. In order to form a vacuum between the outer shell and the inner container, it is common practice to provide an opening in the bottom of the outer shell, which is generally less visible, and to draw a vacuum between the outer shell and the inner container through the opening. And the opening is sealed after vacuum pumping so as to avoid the vacuum state from being damaged.
However, for more applications, manufacturers have designed the existing single-sided bottle as a double-sided bottle. However, the design of double-side opening is not easy to be vacuumized, so that no double-opening bottle in the market has the heat preservation effect. Therefore, it is an important subject to provide a vacuum cup with dual openings and a method for manufacturing the same, which can vacuumize the vacuum cup and maintain a beautiful appearance.
