Can you tell us whether a valve/pump that Company A uses for its Product B is a Mitani’s product or not?


If you already know that Product B of Company A is definitely a Mitani’s product, we can give you an answer immediately. If you are not sure whether a Mitani’s product is used in Product B, we will check and inform you. If Product B was jointly developed with Company A for a special purpose, we can quickly give you an answer. However, if Product B is one of our standard products, it may take some time to respond to your inquiry.
Should we find out that Product B is not by Mitani, we will inform you whether we can provide a similar product or not as soon as possible.

Can you provide us with the same Mitani product that Company A uses for its Product C?

弊社には、一般販売を目的とした汎用製品と、お客様と特定の商品として共同で開発し、お約束(独占契約等)で専用とした製品があります。 A社様が発売されているC商品に採用されている弊社製品が、汎用製品であればいつでも可能です。この弊社製品がA社様の専用製品の場合には残念ながらご要望にはお応え出来ません。

We have standard products which can be sold to any customers, and special products which are jointly developed with a customer for specific use under an agreement (exclusive products). If Product C is one of our standard products, we can provide you with it any time you want. If Product C is an exclusive product for Company A, however, we cannot provide the same product. In this case, we can change , for example, the design or a function of an exclusive product and provide it to you for your own products. Please consult our sales representatives. We will suggest a solution.

Can you decrease/increase the function(spray)load?


Factors affecting and determining the spray load of aerosol cans include the strength of the spring (spring load), hardness of the stem rubber, and inner pressure of the aerosol can. As it is difficult to change the hardness of the stem rubber and the inner pressure, the spray load is changed by adjusting the spring load. We have various springs with different loads for our standard valves. However, the spring load cannot be changed in some products depending on the type of valves or products. We also have trigger type products with a hinge which has a smaller spray load. Factors affecting the spray load of pump products include the spring load, viscosity and sliding resistance of the content, the internal diameter of the cylinder, and the flow resistance of the jet nozzle (internal diameter). We may change the above factors and prepare a product your consumers prefer. Please consult our sales representatives. We will offer you the most appropriate specifications for your product.
The change of the function load automatically leads to a change of the spray load for pump products. Although it is basically possible, there are limitations due to the viscosity of the contents. As it depends on the purpose of use of our product, please consult our sales representatives. We will offer you the most appropriate specifications for your product.
