How to Maintain the Vacuum State of Vacuum Sealed Jars?

I. Correct Usage Methods

Preparation before first use
1.Before using a Vacuum Sealed Jar for the first time, ensure that the jar body and lid are clean and free of impurities. You can wash them with warm water and mild detergent, then rinse thoroughly and dry completely.
2.Check the sealing components such as sealing rings or gaskets to ensure they are intact, without deformation or damage. If there is any damage, replace them in time.

Filling items

1.When putting items to be stored into the jar, ensure that the items are dry and clean. Damp or moist items may affect the vacuum sealing effect.
2.Avoid filling the items too full. Leave some space so that air can be smoothly expelled during the vacuuming process.

Sealing operation

1.Place the lid correctly and ensure that it is completely aligned with the jar body. Follow the instructions in the product manual to perform the sealing operation. Some vacuum sealed jars may require rotating the lid, pressing a button, or using a specific tool to achieve sealing.
2.During the sealing process, ensure the operation is correct and the force is moderate. Excessive force may damage the sealing components, while insufficient force may lead to incomplete sealing.

II. Precautions for Storage Environment

Temperature control

1.Avoid exposing the vacuum sealed jar to extremely high or low temperatures. High temperatures may cause the pressure inside the jar to increase and damage the vacuum state; low temperatures may make the sealing material harden and affect the sealing effect.
2.Try to store the vacuum sealed jar in an environment with stable room temperature, away from heat sources (such as stoves, heaters) and cold sources (such as windows, air conditioner outlets).

Avoid vibration and collision

1.Do not place the vacuum sealed jar in a place that is easily subject to vibration or collision, such as near vibrating equipment, frequently moved furniture, or when not properly fixed during transportation.
2.Vibration and collision may cause the sealing components to loosen or be damaged, thereby destroying the vacuum state.

Prevent direct sunlight

1.Ultraviolet rays in sunlight may cause damage to the jar material and sealing components, reducing their sealing performance. Therefore, store the vacuum sealed jar in a cool place and avoid direct sunlight.

III. Regular Inspection and Maintenance

Check the vacuum state

1.Regularly check the vacuum state of the vacuum sealed jar. You can judge by observing the tightness of the lid, listening for any sound of air leakage inside the jar, or using a special vacuum detection tool.
2.If you find that the vacuum state is weakened, take measures in time to repair or reseal.

Cleaning and maintenance

1.Regularly clean the vacuum sealed jar to keep it clean and hygienic. Use mild detergent and a soft cloth for cleaning. Avoid using rough cleaning tools or corrosive cleaners to prevent damage to the jar body and sealing components.
2.Regularly inspect and maintain the sealing components. If you find signs of wear, aging, or deformation of the sealing ring or gasket, replace it in time.

Correct storage of idle vacuum sealed jars

1.If the vacuum sealed jar is not in use temporarily, clean it and dry it completely, then store it in a dry and ventilated place. You can put some desiccants in the jar to absorb any possible residual moisture and keep the inside of the jar dry.
2.Avoid storing idle vacuum sealed jars in a compressed or stacked state for a long time to prevent damage to the sealing components.
