As shown in FIGS. 1 and 2, the upper end of the container 72 is cut out so that the upper edge of the container 72 curves downward as it goes rearward from the center in the front-rear direction. Thereby, the rear portion of the upper end portion of the operation head 71 is exposed to the outside from the container 72. Further, a second passage hole (passing hole) 72 </ b> B for allowing the front end portion of the nozzle cylinder main body 61 to protrude and retract with respect to the container 72 as the nozzle cylinder 43 moves back and forth is formed in the front portion of the container 72. ing.

  Next, a content discharge method using the discharge container 1 configured as described above will be described. First, against the urging force of the second urging member 78, for example, a portion of the operation head 71 exposed from the container 72, such as the top wall portion 75, is pushed down with respect to the ejection head 23. When the operation head 71 is pushed down, the operation portion 77 of the operation head 71 comes into contact with the sliding contact plate portion 66 of the operation body 62. When the operation head 71 is further pushed down in this state, the operation portion 77 moves downward while being in sliding contact with the sliding contact plate portion 66. Since the operating portion 77 is in sliding contact with the sliding contact plate portion 66, the operating body 62 resists the rearward biasing force of the first biasing member 45 as the operating portion 77 is lowered. The nozzle cylinder main body 61 is moved forward by moving forward. Therefore, as shown in FIG. 4, the nozzle cylinder main body 61 moves forward while sliding on the inner peripheral surface of the interposed cylinder 44 and sliding on the outer peripheral surface of the front and rear cylinder portions 56 of the plug cylinder 42. The front end portion of the main body 61 projects forward through the first passage hole 76 </ b> A of the operation head 71 and the second passage hole 72 </ b> B of the container 72. At this time, the discharge hole 43A of the nozzle cylinder body 61 is opened. Further, the annular projecting portion 75 </ b> A of the top wall portion 75 of the operation head 71 abuts on the annular projecting portion 41 </ b> A of the head body 41.

When the operation head 71 is further pushed down with the front end portion of the nozzle cylinder body 61 protruding from the first passage hole 76A, the top wall portion 75 of the operation head 71 is in contact with the head body 41. 23 moves down together with the operation head 71 as shown in FIG. 5 against the upward biasing force of the stem 26. At this time, the guide protrusion 33A is locked to the upper end of the guide groove 76B or close to the upper end of the guide groove 76B.
Thereby, the contents accommodated in the container main body 2 flows into the inner cylinder portion 51 by the pump mechanism of the pump main body 21, and is transferred into the flow path 42A. Then, the contents in the flow path 42A flow into the nozzle cylinder body 61 through the flow hole 56A and are discharged to the outside through the discharge holes 43A. When the contents are discharged to the outside and the contents are reduced, the inner pressure of the container body 2 is reduced, so that the inner tray 13 is raised in the body portion 11.

Next, when the finger or the like that presses down the operation head 71 is released and the pressed state of the operation head 71 is released, the stem 26 that is biased upward is raised, and the ejection head 23 and the operation head 71 are raised together with the stem 26. To do. Further, the nozzle cylinder main body 61 is retracted from the second passage hole 72 </ b> B of the container 72 and the first passage hole 76 </ b> A of the operation head 71 by the rearward biasing force of the first biasing member 45 and enters the operation head 71. Be contained. The discharge hole 43 </ b> A of the nozzle cylinder main body 61 is closed by the plug cylinder 42.
Further, as the nozzle cylinder main body 61 is retracted, the operating body 62 is also retracted, and the operating portion 77 that is in sliding contact with the sliding contact plate portion 66 is raised. Thereby, the operation head 71 is further raised in addition to the upward movement of the stem 26. In addition, since the second urging member 78 urges the operation head 71 upward with respect to the ejection head 23, the operation head 71 can be raised more reliably with respect to the ejection head 23.
As described above, the contents of the discharge container 1 are discharged to the outside.

According to the discharge container 1 in the present embodiment, the operability of the discharge container 1 is improved because it is not necessary to separately move the nozzle cylinder 43 rearward after discharging the contents. Further, since the protruding operation of the nozzle cylinder main body 61 and the discharge of the contents can be performed simply by pressing the operation head 71 against the container main body 2, the structure of the discharge container 1 can be simplified.
Further, since the second urging member 78 urges the operation head 71 upward with respect to the ejection head 23, the operation head 71 is more reliably directed upward when the depressed state of the operation head 71 is released. Move to restore.

In addition, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the meaning of this invention.
For example, the discharge container is provided with a second urging member for urging the operation head upward with respect to the discharge head, but it is sufficient that at least the first urging member is provided. The structure which does not arrange | position a biasing member may be sufficient.
The first urging member is disposed between the front end of the interposed cylinder and the flange portion of the nozzle cylinder body on the inner side of the interposed cylinder. You may arrange | position behind a part. The same applies to the second urging member. Moreover, although the 1st and 2nd urging | biasing member is formed with the coil spring, you may form using another elastic member.
The outer container includes the operation head and the container, but may not include the container. The operation head has a configuration in which a passage hole is formed while surrounding the pressing head, but a configuration in which a passage hole is not formed without surrounding the pressing head may be employed. In this case, the container accommodates the discharger together with the operation head, and the container is formed with a passage hole.
The discharger has a pump body having a pump mechanism, but may be provided with a stem biased upward, and may be an aerosol type discharger.
The nozzle cylinder has a nozzle cylinder main body and an operating body. However, if the nozzle cylinder can be attached to the head main body, the nozzle cylinder main body and the operation body may be integrated.
The mounting cap is screwed to the mouth portion, but may be attached by other methods such as fitting into the mouth portion.
Although the container main body has an inner tray that slides upward in the body as the contents decrease, the container body is not limited to the configuration having the inner tray.
Although the top wall portion of the operation head pushes down the ejection head, another member may be provided as a push-down portion on the operation head so that the ejection head can be pushed down.

  According to the present invention, the nozzle cylinder does not get in the way in the standby state and not only prevents the appearance of the discharge container from deteriorating, but industrial applicability is recognized for the discharge container having excellent operability.
