I bought it for repair as this cap cracks (breaks through my head) if it is tightened a little stronger.
Although it is saved that the spare is on sale, I think that it is good to make it with a design with a little more strength in the first place.
I bought 35 pieces and 22 pieces were damaged in 2 months so I bought it additionally. The application is storage of neutral detergent. The cap remained closed. Since there is an inner lid, the cap and the detergent are not in contact with each other, but in the explanation of the manufacturer it seems that it may be broken in 2 days if it touches the surfactant. Strength can not be expected.
