Description

A sealed storage container for albino green tea Technical Field

[0001] This utility model belongs to the field of tea storage technology, specifically relating to a sealed storage container for albino green tea. Background Technology

[0002] Albino green tea is a rare variety of green tea, known for its high amino acid content and refreshing taste, making it a favorite among consumers. However, during storage, albino green tea is easily affected by external environmental factors such as humidity, oxygen, light, and temperature, leading to oxidation, moisture absorption, and spoilage, thus affecting the quality and flavor of the tea.

[0003] Currently, there are many types of tea storage containers on the market, such as metal containers, plastic containers, and glass jars. During the storage process, tea leaves produce some residue. Existing storage containers have a simple structure, usually open at the top and sealed at the bottom. This means that the tea residue remains inside the container during storage, making cleaning inconvenient. Therefore, some new types of storage containers have emerged on the market.

[0004] For example, utility model publication CN217515647U discloses a sealed tea storage jar, including a jar body; a lid at the top of the jar body; a bottom plate fixedly connected to the inner wall of the bottom end of the jar body; a set of first through holes on the bottom plate; a pair of symmetrically distributed movable plates slidably connected to the bottom end of the bottom plate; the pair of movable plates are connected to each other by a spring; a push rod is fixedly connected to the side wall of the movable plate, and the push plate extends out of the jar body; a set of second through holes is provided on the movable plate; and a bottom cover is threadedly connected to the inner wall of the bottom end of the jar body. This sealed tea storage jar solves the problem that when tea is sealed and stored, some tea residue is generated during the storage process. This tea residue remains inside the jar, making it inconvenient to clean, and when the tea is taken out for use, some tea residue remains in the tea, affecting the quality of the tea.

[0005] The tea storage container provided by the aforementioned patent is mainly for convenient cleaning of tea residue. However, this type of tea storage container achieves a poor seal by misaligning its first and second through holes, resulting in inadequate sealing. Furthermore, it lacks specific moisture-proof and light-proof features designed for the characteristics of albino green tea. During storage, external moisture and oxygen easily enter the container, causing the tea to become damp and oxidize. Sunlight exposure accelerates the decomposition of the tea's active ingredients, reducing its nutritional value and taste. Additionally, it cannot monitor the internal temperature and humidity of the storage container. Summary of the Invention
