[Problem to be solved] To provide a spray nozzle and an aerosol product in which the density difference between the center and the periphery is small. And to provide a spray nozzle and an aerosol product which give a spray pattern in which the spray density of peripheral portion does not decrease so much. [Solution] A nozzle 10 for an aerosol product, in which the shape along the spray direction of the spray pattern F becomes a semi parabolic shape. The nozzle 10 in which the spray pattern is planar or plate-like surrounded by a semi parabola-like shape and a center line C, and in which the planar spray thereof becomes a shape such that a plurality of sheets is arranged at an equal interval in a circumferential direction around the center C of the nozzle. The cross section of the spray pattern F can be formed into various shapes of an I type, a Y type, an X type, a V type, an S type etc according to the shape of slit passage of the front face of the nozzle 10. An aerosol product E equipped with a container body 31, a valve 32 provided in the upper end of the container body, and a nozzle 10 attached to the valve thereof.
A spray nozzle of which a contour portion of a spray pattern is pulled inside by spraying, a shape along a spray direction of the spray pattern being formed into an approximately semi parabolic shape.
A spray nozzle having, inside thereof, a passage to make a content pass through, a convergent taper portion or a gradient portion provided in the front end of the passage, and a small diameter nozzle hole passage extending from a front end of the taper portion or the gradient portion, wherein a slit passage which connects a nozzle hole which is the opening end of the nozzle hole passage and an outer space is provided.
A spray nozzle having, inside thereof, a passage to make a content pass through, a convergent taper portion or a gradient portion provided in the front end of the passage, wherein a slit passage which connects a nozzle hole in which a part of the taper portion or the gradient portion is made to open, and an outer space is provided.
A spray nozzle having an inner nozzle equipped with a passage to make a content pass through and a convergent taper portion provided in the front end of the passage, and an outer nozzle covered on the inner nozzle, being equipped with a slit passage connecting inside and outside thereof, wherein a spray passage connecting the taper portion and the slit passage is formed between the inner nozzle and the outer nozzle.
A spray nozzle having a nozzle body equipped with a passage to make a content pass through, a convergent taper portion provided in the front end of the passage, a squeezing passage extending from the front end of the taper portion, an empty space connected with the squeezing passage, and a slit passage connecting the empty space and outside, and an outer nozzle housed in the empty space, wherein a spray passage which connects the squeezing passage and the slit passage is formed between the outer nozzle and the inner surface of the empty space.
