Ceramic vessel opening part sealing structure and preparation method thereof

Abstract

The invention belongs to the technical field of storage sealing vessels, and particularly relates to a ceramic vessel opening part sealing structure and a preparation method thereof. The sealing structure comprises an opening part and a sealing cover. At least two sealing sections are arranged between the opening part and the sealing cover. The two sealing sections comprise a rubber sealing ring which is arranged on the upper surface of the opening part and / or the lower surface of the sealing cover and surrounds the axis of the opening part, and at least one circle of matting sealing ring which is located on the inner side of the rubber sealing ring and surrounds the axis of the opening part. By the adoption of the sealing structure, storage quality of reserved substances can be guaranteed while a normal packaging effect on the opening part by a traditional sealing cover is ensured. In the machining process, a carborundum grinding mode is used, and the top of an annular sealing ridge conducts rotating and grinding relative to the corresponding surface of the sealing cover or the opening part so that an annular sealing groove can be formed; and the top of an annular supporting ridge conducts rotating and grinding relative to the corresponding surface of the sealing cover or the opening part so that an annular supporting groove can be formed, and thus reliable machining of the structure can be guaranteed conveniently, rapidly and efficiently.

Description

technical field [0001] The invention belongs to the technical field of storage and sealing containers, and in particular relates to a ceramic container mouth sealing structure and a preparation method thereof. Background technique [0002] Baijiu is a unique distilled liquor in China and one of the six largest distilled liquors in the world. When brewing wine, people will store the wine produced after grain fermentation and distillation into ceramic jars and seal them, so that the wine in the ceramic jars will undergo physical and chemical reactions during storage, making the stored products more mellow and thick. Currently known techniques for sealing the mouth of wine jars mainly contain two types: one is to directly cover and seal the lid made of pottery clay. Gradually abandoned by people. The most widely used is the use of plunger caps for sealing. The plunger-type cap seal is a columnar ceramic structure plug that extends downward from the cover to the mouth, and th...

Problems solved by technology

But the fatal weakness of this plunger-type cap seal is that after the wine tank continues to evaporate, it will condense into a liquid state on the surface of the plastic or silicone sleeve, and then fall back to the ceramic container; such a long-term reciprocating cycle will lead to plasticization The smell of medicine or rubber will be brought into the storage, which will cause the storage to be destroyed, and it is not suitable for drinking.

How to find a new type of ceramic container or even a mouth sealing structure popularized in all ceramic containers, so as to solve the poor packaging conditions widely encountered in current ceramic containers and even all ceramic containers, is a technical problem to be solved urgently in this field in recent years
