Next, a method of using the discharge device 1 having the above configuration will be described.
First, for example, when the stopper member 8 is attached to the guide tube portion 13 at the time of manufacturing the dispenser 1, the both peripheral edges of the main body tube portion 41 are in contact with the outer peripheral surface of the guide tube portion 13. While grasping the operation part 42, the operation part 42 is pushed inward in the radial direction. At this time, first, the projecting portions 41 </ b> B formed at both peripheral edges of the main body cylinder portion 41 abut on the guide cylinder portion 13. And, when the main body cylinder part 41 is pushed inward in the radial direction in this state, the interval X between the two peripheral end edges of the main body cylinder part 41 gradually increases from the inner side in the radial direction to the outer side. The main body cylinder part 41 introduces the guide cylinder part 13 between the peripheral end parts with little catching while elastically deforming so that the side opening 41A expands in the circumferential direction.

  Then, when the main body cylinder portion 41 is further pushed inward in the radial direction, both peripheral end portions of the main body cylinder portion 41 are elastically deformed so as to further expand the side opening 41A, and the outer peripheral surface of the guide cylinder portion 13 It is guided along the outer peripheral surface while being in sliding contact. At this time, since the groove portions 43 are formed in portions of the main body cylinder portion 41 located on both sides of the operation portion 42 in the circumferential direction on the outer peripheral surface of the connection portion, the main body cylinder portion 41 starts from the groove portions 43. As shown, the side opening 41A is easily elastically deformed.

After that, when the main body cylinder portion 41 is further pushed inward in the radial direction, both peripheral end portions of the main body cylinder portion 41 are deformed and deformed so as to reduce the side opening 41A, and are formed on the outer peripheral surface of the guide cylinder portion 13. It is guided along the outer peripheral surface while making sliding contact. At this time, the main body cylinder portion 41 is easily deformed and deformed so as to reduce the side opening 41A starting from these groove portions 43, as described above.
The stopper member 8 is attached to the guide tube portion 13 as described above.
In this state where the stopper member 8 is attached to the guide tube portion 13, the upper end edge of the main body tube portion 41 approaches or comes into contact with the lower end edge of the head tube portion 33, and the lower end edge of the main body tube portion 41 is the top wall portion. 11, the downward movement of the pressing head 6 is restricted.

Subsequently, for example, when the stopper member 8 is removed from the guide tube portion 13 when the dispenser 1 is used, for example, the operating portion 42 is directed radially outward with a finger or the like hung on the finger hook portion 45. pull. When the operation portion 42 is pulled, both peripheral end portions of the main body cylinder portion 41 are elastically deformed starting from the groove portion 43 so as to enlarge the side opening portion 41A, and are slidably contacted with the outer peripheral surface of the guide tube portion 13. Guided along the surface. When the main body cylinder portion 41 is further pulled outward in the radial direction, both guide ends of the peripheral end portions of the main body cylinder portion 41 are restored and deformed starting from the groove portion 43 so as to reduce the side opening 41A. 13 is guided along the outer peripheral surface while being in sliding contact with the outer peripheral surface.
As described above, the stopper member 8 is removed from the guide tube portion 13.

In this state where the stopper member 8 is removed, when the pressing head 6 is pushed down, the stem 21 is moved downward. Then, following the movement of the stem 21, the piston member moves downward while being in sliding contact with the inner peripheral surface of the cylinder 22. As a result, the content in the cylinder 22 is compressed, and the compressed content in the cylinder 22 enters the stem 21 and moves upward in the stem 21.
Thereafter, when the pressing down of the pressing head 6 is released, the piston member is restored and moved upward while being in sliding contact with the inner peripheral surface of the cylinder 22 by the upward biasing force of the biasing member. Thereby, the inside of the cylinder 22 is depressurized, and the contents accommodated in the container body 2 are sucked into the cylinder 22 through the pipe 24.

According to the dispenser 1 having the above-described configuration, the main body cylinder portion 41 is easily elastically deformed so that the side opening 41A expands and contracts in the circumferential direction starting from the groove portion 43. Therefore, the stopper member 8 is guided by the guide cylinder portion. 13 can be easily attached and detached.
Further, when the stopper member 8 is mounted on the guide tube portion 13, the guide tube portion 13 can be introduced with little catch between the peripheral end portions of the main body tube portion 41, so that the stopper member 8 can be mounted more easily. .

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 stopper member is detachably attached to the guide tube portion, but may be detachably attached to the stem with the intermediate portion as a stem.
The groove portion is formed in a portion of the main body cylinder portion located on both sides of the operation portion in the circumferential direction on the outer peripheral surface of the connection portion, but it may be formed in at least one side.
The interval between the peripheral edges of the main body cylinder part does not need to gradually increase from the radially inner side toward the outer side.
The groove portion is formed continuously over the entire length of the main body cylindrical portion, but may be formed intermittently, and at least of the portions located on both sides of the operation portion on the inner peripheral surface of the connection portion in the circumferential direction. It may be formed on one side.
Further, the groove may be formed on both the outer peripheral surface and the inner peripheral surface of the connection portion.
As long as the operation part protrudes from the main body cylinder part toward the outer side in the radial direction, the operation part may not have the finger hook part.

  According to the present invention, industrial applicability is recognized with respect to a dispenser in which the stopper member can be easily attached to and detached from the dispenser body.
