In this article, we made a summary about the problems and troubles that are likely to occur when using stainless steel containers.
This article also explained how we respond to inquiries from customers using Nitto Kinzoku’s containers.
Also, please feel free to contact us if you have any questions about the questions which are not listed.
Problems when using our containers
When the container becomes rusty
It depends on the usage environment, but we recommend you to purchase a new one.
It increases the risk of foreign matter contamination such as missing the container from the rusted area.
*Rust can be removed to some extent by rubbing it with a fine abrasive, but it may be scratched and cause new rust. Please try it carefully at your own risk. Also, wash and dry immediately after removing rust is essential.
Please feel free to contact our company if you have any trouble with the measures to prevent the recurrence of rust when you replace a new one.
Cannot open the lid of the container
Please warm the container with warm water from outside.
If the container is tightened with a clip or band, it may be difficult to remove the lid.
This is because the temperature of the contents is colder than when the lid is closed, and the inside of the container is in a state of decompression, and the lid and the container are in close contact.
It takes a little time, but if you raise the temperature of the inside by warming it with hot water, it will be easier to open it.
As a countermeasure, a valve for introducing outside air can be installed on the lid of the container, or a rubber plug can be installed by opening an air vent hole.
How long does the container last?
There is no fixed life or warranty period for a stainless steel container.
Our company does not set a specific life or warranty period because the content, frequency of use, and other parameters may vary depending on the usage environment.
Please consider replacing the product in consideration of the hygiene grade required for the usage environment such as the degree of rust and dirt.
Gasket difficult to be set (Clip type container and Lever Ring type)
Please check the video below for tips on gasket settings.
*The shape of the gasket is different from that of the moving image when the container diameter of the clip type container or band type container is large (565 mm ~).
Clip Type Container (A-Type Gasket)
Tips for setting
Set a part of the packing on the edge of the container first, and spread it out little by little from that part.
Lever Ring Container (L type Gasket)
Tips for setting
Set a part of the packing on the lid, and then put it on with both hands.
When gasket has deteriorated (torn, become smelly, discolored, etc.).
We recommend you to buy a new one to replace it.
If the gasket became loose (swollen), torn, smelly, or discolored
The quality of the contents may be adversely affected, for example, by impairing the airtightness of the container or mixing in foreign matter.
Consumables such as gasket can be purchased from one item, so please contact the agent who purchased the container.
If you are unsure of the type of packing or want to consult with our company about the material, contact SMC.
If you are having trouble with the compatibility of the gasket and the contents, please feel free to contact our company.
