Latest Patents

One of Naruo's latest patents is a resin tube fitting designed to prevent backwaters between its body and inner ring. This fitting comprises a body, an inner ring, and a union nut. The body features main, outer, and inner sleeves, along with a groove. The inner ring includes a cylinder, an insert, and outer and inner protrusions. The union nut consists of a body and a pressing member. The inner sleeve has a through hole that serves as a channel, while the inner protrusion extends from the cylinder in an axial direction to contact the inner sleeve. This innovative design ensures that the inner diameter of the inner protrusion is not less than the minimum inner diameter of the inner sleeve, enhancing its overall performance.

Another notable patent is a method for manufacturing a resin pipe joint. This method involves preparing a mold and a supply device for molten resin. The mold consists of a first mold for the outer shape and a second mold for the inner shape of the joint body. By combining these molds, a cavity is formed for injecting molten resin. The process includes supplying the molten resin to the cavity and solidifying it after stopping the supply. The second mold features a gap that connects the cavity to a discharge space, allowing gas to flow, which is crucial for the manufacturing process.
