  The discharge tool of Patent Document 1 is composed of four parts, and the discharge tool of Patent Document 2 is composed of three parts, both of which are nozzle portions (discharge heads, nozzle members), Since its operation part (press operation part, lever member) is a separate body, in Patent Documents 1 and 2, it is necessary to remove the operation part when cleaning the nozzle part after discharging the contents. There is a concern that it will take time. There is room for improvement here.

  In view of such circumstances, the present invention provides a nozzle for simultaneously discharging two types of contents from a first stem and a second stem that are provided on one end side of a cylindrical aerosol can so as to be adjacent to each other in the radial direction. In the unit, the manufacturing cost can be reduced as compared with the discharge tools disclosed in Patent Documents 1 and 2 above, and the part removal work accompanying the cleaning of the passage for discharging the contents, specifically, the discharge head from the pedestal The purpose is to make it easy to perform a series of operations such as a removal operation, a cleaning operation of the discharge head, and a mounting operation of the discharge head on a pedestal.

  Further, the present invention is a two-component dispenser including the nozzle unit, and enables the production cost to be reduced as compared with the two-component dispenser disclosed in Patent Document 1 and the dual aerosol container disclosed in Patent Document 2, and after use. The purpose of this is to make it easy to carry out part removal work accompanying cleaning.

  The present invention is a nozzle unit for simultaneously discharging two kinds of contents from a first stem and a second stem provided on one end side of a cylindrical aerosol can so as to be adjacent to each other in the radial direction. It is composed of two parts, a pedestal that is detachably mounted so as to expose the first stem and the second stem on the one end side of the can, and a discharge head that is detachably attached to the upper part of the pedestal. The head is individually connected to the first stem and the second stem, and a nozzle having a passage for causing the contents discharged from the first stem and the second stem to merge and discharge to the outside, And a frame portion for supporting the pedestal so as to be able to tilt in response to a pushing operation of the nozzle. Vomiting Having an engaged portion which the engaging portion of the head is locked detachably, and characterized in that.

  Moreover, both dimensions of the pedestal and the discharge head in the direction along the central axis of the aerosol can are made as short as possible as compared with the case where the discharge head is configured to cover the outside of the pedestal. Therefore, it is possible to suppress an increase in material costs of the pedestal and the ejection head.

  Further, the discharge port side of the nozzle is supported in a cantilever shape on the frame portion via an elastic arm, and the passage extends from the first stem and the second stem along the central axis of the aerosol can. It is preferable that the two types of contents discharged in this manner have a shape that is directed outward while changing the direction outward in the radial direction of the aerosol can.

  According to this configuration, when the nozzle is pushed, the nozzle is tilted according to the principle of scissors. As a result, the force required for the pushing operation is reduced, and the amount of tilting of the nozzle accompanying the pushing operation is increased, so that the contents can be reliably discharged with a relatively small force. It becomes possible.

  And according to the said structure, since it becomes possible for a user to receive two types of contents discharged from the said channel | path near the outer periphery of the said aerosol can, it becomes clear that a user becomes easy to receive.

  Further, the direction changing portion of the passage is configured to open to the outside, and a nozzle cover for opening and closing the opening portion is overlaid on the upper side of the nozzle. The nozzle is connected to the nozzle on the side opposite to the discharge port so as to be aligned in a straight line, and is configured to be overlapped on the upper side of the nozzle by being bent upward with the hinge as a fulcrum. Is preferred.

  According to this configuration, when the nozzle cover is tilted away from the nozzle, the direction changing portion of the passage is exposed to the outside and exposed, so that the entire passage can be washed directly with water or the like. It becomes like this.

  As a result, after discharging the contents from the aerosol can, the two types of contents adhering to the passage can be washed out relatively easily and cleanly. It will be easy to do.

  Further, the direction changing portion of the passage is configured to open outward, and a nozzle cover for opening and closing the open portion is connected to the nozzle in the vicinity of the open portion via a hinge. The nozzle cover is tilted so as to be inclined to the side opposite to the discharge port with the hinge as a fulcrum, so that the open portion is closed, while being separated from the discharge port with the hinge as a fulcrum. It is preferable that the opening portion is configured to be opened by being tilted.

  According to this configuration, when the nozzle cover is tilted away from the nozzle, the direction changing portion of the passage is exposed to the outside and exposed, so that the entire passage can be washed directly with water or the like. It becomes like this.

  As a result, after discharging the contents from the aerosol can, the two types of contents adhering to the passage can be washed out relatively easily and cleanly. It will be easy to do.

  In addition, the pedestal may be configured to include an operation portion for detaching the locked portion from the locking portion of the discharge head in response to a radially inward pushing operation. preferable.

  According to this configuration, it is possible to relatively easily perform the act of detaching the locked portion of the pedestal from the locking portion of the discharge head by the operation portion for receiving the pushing operation.

  The single lateral hole 61e is provided in a half region of the nozzle 61 in the longitudinal direction. One end side of the horizontal hole 61e communicates with each of the first vertical hole 61c and the second vertical hole 61d in the axial direction, and the other end side of the horizontal hole 61e is opened outward. The open end (outside opening) of the other end of the horizontal hole 61e serves as a discharge port for the two types of contents.

  On the upper side of the nozzle 61, a nozzle cover 63 for opening and closing the upper openings of the first vertical hole 61c and the second vertical hole 61d is superimposed.

  The nozzle cover 63 is connected to the side opposite to the discharge port of the nozzle 61 so as to be aligned in a straight line via a hinge 64, and is folded upward with the hinge 64 as a fulcrum so as to be superimposed on the upper side of the nozzle 61. It has become.

  The nozzle cover 63 is provided with a depressed portion 63a. The depressed portion 63a covers the entire first vertical hole 61c and the second vertical hole 61d in a state where the nozzle cover 63 is superimposed on the nozzle 61, and the inner bottom surface of the depressed portion 63a is the first vertical hole. The upper opening of 61c and the second vertical hole 61d is closed.

  A convex lid portion 63b is provided in the depressed portion 63a. The lid 63 b is fitted into the upper openings of the first vertical hole 61 c and the second vertical hole 61 d of the nozzle 61 in a state where the nozzle cover 63 is superimposed on the nozzle 61, so that the nozzle cover 63 is attached to the nozzle 61. It is provided for positioning.

  Further, an operation piece 63c and a protrusion 63d are provided on the end surface of the nozzle cover 63. The operation piece 63 c is provided to separate the nozzle cover 63 from the nozzle 61. The protruding portion 63d is locked to the receiving-side protruding portion 61f provided on the nozzle 61 when the nozzle cover 63 is overlapped with the nozzle 61, so that the overlapping state is maintained. Is provided.

  The frame portion 62 supports the nozzle 61 so as to be tiltable, and has a configuration in which the lower corner portions of the first standing wall portion 62a and the second standing wall portion 62b are connected to each other by a connecting portion 62c. The nozzle 61 is supported in a cantilever shape via an elastic arm 65 on the connecting portion 62 c of the frame portion 62.

  The 1st standing wall part 62a and the 2nd standing wall part 62b are arrange | positioned so that it may oppose in parallel, and the nozzle 61 is arrange | positioned non-contactingly in those opposing space. The first standing wall 62 a and the second standing wall 62 b are higher than the upper ends of the nozzle 61 and the nozzle cover 63. Further, the outer surfaces of the first standing wall portion 62 a and the second standing wall portion 62 b are formed in a rounded shape so as to be flush with the outer peripheral surface of the outer cylinder portion 52 of the base 5.

  And the drooping piece 62d which protrudes 1 each downward is provided in the lower end of the 1st standing wall part 62a and the 2nd standing wall part 62b. Locking portions 62e are provided at predetermined positions on the outer surfaces of both hanging pieces 62d. The locking portion 62e is a horizontally long protrusion.

  As shown in FIG. 2, when the discharge head 6 is connected to the pedestal 5, the hanging piece 62 d is inserted into the facing space between the inner cylindrical portion 51 and the outer cylindrical portion 52 of the pedestal 5, The part 62e is detachably locked to the locked part 52a of the base 5.

  Next, a procedure for attaching the nozzle unit 3 to the aerosol can 2 will be described.

  First, as shown in FIG. 2 from the state of FIG. 1, the base 5 of the nozzle unit 3 is attached to the aerosol can 2.

  At this time, the inner cylinder part 51 of the base 5 is pressed against the valve body 41 of the valve 4 of the aerosol can 2 so as to be fitted to the aerosol can 2 side, but the hook 51a of the inner cylinder part 51 is the valve body. When locked to the lower outer peripheral edge of 41, the pedestal 5 is attached to the aerosol can 2 so that it cannot be easily detached.

  Next, as shown in FIG. 3 from the state of FIG. 2, the ejection head 6 is mounted on the base 5. At this time, the hanging piece 62d of the ejection head 6 is pressed against the pedestal 5 side so as to be inserted into the space between the inner cylinder portion 51 and the outer cylinder portion 52 of the pedestal 5, but the first standing wall portion of the ejection head 6 is pressed. 62a, the lower end of the second standing wall portion 62b is in contact with or close to the upper end of the outer cylindrical portion 52 of the pedestal 5, and the locking portion 62e of the hanging piece 62d of the ejection head 6 is locked to the locked portion 52a of the outer cylindrical portion 52. When it is locked, the ejection head 6 is mounted on the pedestal 5 so that it cannot be easily detached.

  In addition, when the locking portion 62e is securely locked to the locked portion 52a in this way, for example, a “click” sound is made, so that it can be recognized by sound that the mounting of the ejection head 6 is completed. Become.

  Next, the operation | movement at the time of use of the two-component ejector 1 assembled as mentioned above is demonstrated.

  When the user performs a pushing operation so that the nozzle cover 63 of the ejection head 6 is pushed down with a finger, the nozzle 61 integrated with the nozzle cover 63 is tilted downward with the connecting portion 62c of the frame portion 62 as a fulcrum, Thereby, the first stem 42 and the second stem 43 of the aerosol can 2 are pushed down.

  As a result, the two types of contents of the aerosol can 2 simultaneously flow from the first stem 42 and the second stem 43 into the first vertical hole 61c and the second vertical hole 61d of the nozzle 61, where 90 degrees direction It is converted and flows into the horizontal hole 61e of the nozzle 61.

  In the horizontal hole 61e, the two kinds of contents are merged and discharged from the outer opening (corresponding to the discharge port of the nozzle 61) of the horizontal hole 61e toward one radial direction of the aerosol can 2. Become.

  After the contents of the aerosol can 2 are discharged in this manner, the contents are passed through the passage of the nozzle 61 (first lower opening recess 61a, second lower opening recess 61b, first vertical hole 61c, second vertical hole. It is preferable to clean 61d and the lateral hole 61e).

  This is because if the contents are left for a long time without being washed after the contents are discharged, the contents present in the passage may be hardened and clogged. Moreover, when the content is a composition for hair dyeing, the dye in the composition remaining in the passage may change color, which may adversely affect the dyed surface at the next use. In order to prevent such clogging and discoloration of the composition, it is preferable to wash the passage of the nozzle 61 after the contents are discharged.

  Next, a procedure for cleaning the nozzle 61 will be described.

  The discharge head 6 is removed from the base 5. In that case, the discharge head 6 may be pulled upward so as to be separated from the pedestal 5 while the operation portion 52b of the pedestal 5 is pushed.

  When the pushing operation is performed, the locked portion 52a of the base 5 is elastically deformed outward, so that the locked portion 52a can be detached from the locking portion 62e of the ejection head 6. It becomes a state. In such a state, if the ejection head 6 is pulled upward so as to be separated from the pedestal 5, the ejection head 6 can be detached from the pedestal 5.

  If the nozzle cover 63 is lifted upward after the ejection head 6 is removed in this manner, the protrusion 63d of the nozzle cover 63 is disengaged from the receiving protrusion 61f of the nozzle 61, and the hinge 64 is removed. It will tilt around the fulcrum. Accordingly, the first vertical hole 61c and the second vertical hole 61d of the nozzle 61 and the recessed portion 63a and the lid portion 63b of the nozzle cover 63 are exposed to the outside.

  In such a state, the first vertical hole 61c, the second vertical hole 61d, the first lower opening recess 61a, the second lower opening recess 61b of the nozzle 61, the recessed portion 63a and the lid portion 63b of the nozzle cover 63, , Can be washed directly with water. Thereby, it becomes possible to wash off the two kinds of contents adhering to them relatively easily and cleanly.

  Such a cleaning operation of the nozzle 61 can be performed even when the ejection head 6 is not removed from the base 5. However, it can be said that the cleaning operation of the nozzle 61 is easier since the ejection head 6 is easier to hold when the ejection head 6 is removed as described above.

  As described above, in the embodiment to which the present invention is applied, the nozzle unit 3 provided in the two-liquid discharger 1 is configured by the two component structures of the base 5 and the discharge head 6. Compared to the discharge tool, the number of component parts of the nozzle unit 3 is reduced, and the manufacturing cost can be reduced. Accordingly, the manufacturing cost of the two-liquid ejector 1 including the nozzle unit 3 can be reduced as compared with the two-liquid ejector disclosed in Patent Document 1 and the dual aerosol container disclosed in Patent Document 2.

  In addition, when the nozzle 61 is washed after the two kinds of contents are discharged from the aerosol can 2, the direction of the contents in the passage of the nozzle 61 is determined by pulling the nozzle cover 63 away from the nozzle 61 of the discharge head 6. The conversion part (the first vertical hole 61c and the second vertical hole 61d) can be exposed to the outside.

  Thus, by washing the entire passage of the nozzle 61 directly with water or the like, the two kinds of contents adhering to the passage can be washed out relatively easily and cleanly. As described above, the parts can be easily removed along with the cleaning of the passage of the nozzle 61, and the ejection head 6 after use can be maintained relatively easily.

  In addition, when the configuration of this embodiment is adopted, the following effects can be obtained.

  (1) The height of the first standing wall 62 a and the second standing wall 62 b of the frame 62 is set to a position higher than the nozzle cover 63. With this setting, it becomes difficult to touch the nozzle cover 63 due to the presence of the first standing wall portion 62a and the second standing wall portion 62b, so that the nozzle 61 is not easily pushed by mistake, and erroneous operation can be prevented.

  (2) Since the outer surfaces of the first standing wall 62a and the second standing wall 62b and the outer peripheral surface of the base 5 are connected to be flush with each other, the nozzle unit 3 has no irregularities on the outer peripheral surface. 3 Outline design is 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 made to be flush with each other, the outer design of the two-liquid ejector 1 is such that there are no irregularities on the outer peripheral surface of the two-liquid ejector 1 Become simple and smart. This increases the sense of unity with the aerosol can, which makes it easier to grip and improves operability during use.

  Moreover, as compared with the case where the discharge head 6 is configured to cover the outside of the pedestal 5, the dimensions of the pedestal 5 and the discharge head 6 in the direction along the central axis 100 of the aerosol can 2 are made as much as possible. Since it can be shortened, an increase in material costs of the base 5 and the ejection head 6 can be suppressed.

  (3) Since the nozzle 61 is supported in the form of a cantilever on the frame portion 62 via the elastic arm 65, when the nozzle 61 is pushed, the nozzle 61 is tilted according to the principle of scissors. . As a result, the force required for the pushing operation is reduced and the amount of tilting of the nozzle 61 accompanying the pushing operation is increased, so that the contents can be reliably discharged with a relatively small force. become.

  (4) Since the two types of contents in the aerosol can 2 are discharged radially outward, the two types of discharged contents can be received by the user near the outer periphery of the aerosol can 2. This makes it easier for users to receive.

  In addition, this invention is not limited only to the said embodiment, It can change suitably in the range equivalent to the claim and the said range.

  Further, a structure in which the nozzle cover 63 is eliminated is also included in the present invention. In this case, the passage of the nozzle 61 needs to have a configuration in which the first vertical hole 61c and the second vertical hole 61d are eliminated and the first lower opening recess 61a and the second lower opening recess 61b are communicated with the horizontal hole 61e. .

  (2) In the above embodiment, the first and second standing wall portions 62a and 62b in the frame portion 62 of the ejection head 6 are set higher than the nozzle cover 63, but the present invention is limited to this. It is not something.

  For example, although not shown, the first standing wall 62a and the second standing wall 62b are set to the same height as the nozzle cover 63, or the first standing wall 62a and the second standing wall 62b are set lower than the nozzle cover 63. It is possible to do.
