The ejection port of Patent Document 1 is composed of four parts, and the ejection port of Patent Document 2 is composed of three parts, but all are a nozzle part (discharge head, nozzle member) and an operation part thereof ( Since the pressing operation part and the lever member) are separate bodies, in Patent Documents 1 and 2, when cleaning the nozzle part after discharging the contents, it is necessary to remove the operation part without fail, etc. . There is room for improvement here.

In view of such circumstances, the present invention provides a nozzle unit for simultaneously discharging two types of contents from a first stem and a second stem installed so as to be adjacent to each other in a radial direction on one end of a cylindrical aerosol can, , while making it possible to reduce the manufacturing cost compared to the discharge ports of Patent Documents 1 and 2, and at the same time, the component removal operation accompanying the cleaning of the passage for discharging the contents, specifically, by removing the discharge head from the pedestal An object of the present invention is to make it possible to easily perform a series of operations such as dispensing, cleaning the discharge head, and mounting the discharge head on a pedestal.

Further, in the present invention, in the two-liquid ejector having the nozzle unit, compared with the two-liquid ejector of Patent Document 1 and the twin-type aerosol container of Patent Document 2, the manufacturing cost can be reduced, and care after use , specifically, to make it possible to easily perform a component removal operation accompanying cleaning.

The present invention is a nozzle unit for simultaneously discharging two types of contents from a first stem and a second stem installed so as to be adjacent to each other in a radial direction on one end side of a cylindrical aerosol can, the one end side of the aerosol can It consists of a pedestal detachably mounted to expose the first stem and the second stem, and two parts of a discharge head detachably attached to the upper portion of the pedestal, the discharge head comprising: A nozzle separately connected to the first stem and the second stem, and having a passage for discharging the contents discharged from the first stem and the second stem to the outside by merging; and a frame portion for supporting the nozzle so as to be able to tilt in response to a pressing operation of the nozzle, wherein the pedestal has a locking portion of the discharge head is detachable. It is characterized in that it has a blood (被) locking part that is fixedly caught and fixed.

In this configuration, since the nozzle unit has a two-part structure of the pedestal and the discharge head, the number of constituent parts of the nozzle unit is reduced as compared with Patent Documents 1 and 2, and it is possible to reduce the manufacturing cost.

In addition, when cleaning the passage, only removing the discharge head is sufficient, so that the component removal operation accompanying cleaning can be performed more easily compared to Patent Documents 1 and 2 above.

In this way, the component removal operation accompanying the cleaning of the passage of the nozzle 61 can be easily performed, and the cleaning of the discharge head 6 after use can be performed relatively easily.

In addition, when the structure of this embodiment is employ|adopted, the following effects are acquired further.

(1) The height of the first upright wall portion 62a and the second upright wall portion 62b of the frame portion 62 is set to a position higher than that of the nozzle cover 63 . With this setting, the presence of the first upright wall portion 62a and the second upright wall portion 62b makes it difficult to touch the nozzle cover 63, so that the nozzle 61 is less likely to be operated by an erroneous pressing operation, thereby preventing erroneous operation. can be prevented

(2) Since the outer surfaces of the first upright wall portion 62a and the second upright wall portion 62b and the outer peripheral surface of the pedestal 5 are connected face to face, there is no unevenness on the outer peripheral surface of the nozzle unit 3 . For example, the external design of the nozzle unit 3 becomes simple and smart. In addition, since the outer peripheral surface of the pedestal 5 and the outer peripheral surface of the aerosol can 2 are connected face-to-face, irregularities do not exist on the outer peripheral surface of the two-liquid ejector 1, etc. )'s external design becomes simple and smart. Thereby, since the sense of unity with the aerosol can becomes large, it becomes easy to hold, and the operability at the time of use becomes favorable.

In addition, for example, the central axis 100 of the aerosol can 2 in the pedestal 5 and the discharge head 6 compared to the case where the discharge head 6 is covered on the outside of the pedestal 5 . Since it becomes possible to shorten all the dimensions along the direction as much as possible, it becomes possible to suppress an increase in the material cost of the pedestal 5 and the discharge head 6 .

(3) Since the nozzle 61 is supported by the frame part 62 via the elastic arm 65 in a cantilever shape, when the nozzle 61 is pressed, the nozzle 61 is tilted by the principle of a lever. will become As a result, the force required for the pressing operation is reduced and the amount of inclination of the nozzle 61 accompanying the pressing operation is increased, so that the contents can be reliably discharged with a relatively small force.

(4) Since the two types of contents in the aerosol can 2 are discharged in the radial direction outward, the user can receive the two types of contents to be discharged near the outer periphery of the aerosol can 2 Therefore, it becomes easier for the user to receive it.

In addition, this invention is not limited only to the said embodiment, It is possible to change suitably within the range of a claim and the range equivalent to the said range.
