The shoulder portion 170 having such a configuration is coupled to the neck portion 122 through the shoulder portion through hole (171a) is aligned with the neck portion 122 and the shoulder portion circumferential wall portion 172.

The button 150 includes a button inclined surface portion 151, a button side wall portion 152 bent from the circumferential edge of the button inclined surface portion 151, and a vertical flow path pipe portion 153 that is erected on the bottom surface of the button inclined surface portion 151 Has.

The button inclined surface portion 151 has an inclined passage connected to the vertical passage pipe portion 153.

The button 150 having this configuration is installed so that the vertical flow path pipe portion 153 is aligned with the upper opening of the cylinder 115. The button 150 may move up and down along the button guide wall 173 through the button side wall part 152,

The pumping unit 140 is a guide coupled to the annular pumping piston 141, the operating shaft 145 and the valve body 143, the button 150 and the operating shaft 145 installed inside the cylinder 115 It has a shaft 142, a support member 146 installed to surround the guide shaft 142, and a return spring 144 installed to support both ends of the guide shaft 142 and the support member 146.

The pumping piston 141 is installed to be in close contact with the inner surface of the cylinder 115 and in contact with the side of the operating shaft 145. An intermediate storage chamber 115b is formed between the pumping piston 141 and the bottom surface of the cylinder 115.

The pumping piston 141 is installed inside the cylinder 115 to be spaced apart from the lower end of the guide shaft 142. When the pumping piston 141 pressurizes the button 150 to lower the guide shaft 142 and the operation shaft 145, the guide shaft 142 and the operation shaft 145 descend a certain distance and then begin to descend. do.

The actuating shaft 145 has an actuating shaft flow path formed along the longitudinal direction thereof.

The operation of a conventional pumping tube container having the above-described configuration will be described with reference to FIG. 20 as follows. For convenience of explanation, it is assumed that the container cap 119 is separated from the shoulder 170 and the contents are stored in the intermediate storage chamber 115b.

First, when the button 150 is pressed downward while holding the storage container body part 121 by hand, the guide shaft 142 and the operation shaft 145 are lowered by the downward pressing motion of the vertical flow pipe part 153. do. The lowering motion of the operating shaft 145 opens the space between the operating shaft 145 and the pumping piston 141. While the guide shaft 142 descends, an elastic force is accumulated in the return spring 144.

When the guide shaft 142 descends and presses the pumping piston 141, the pumping piston 141 descends together with the guide shaft 142 and the operation shaft 145.

When the pumping piston 141 descends, the contents in the intermediate storage chamber 115b sequentially pass through the flow path formed on the operation shaft 145, the vertical flow pipe part 153, and the button inclined surface part 151 to be discharged to the outside.

Next, when the pressing force on the button 150 is released, the button 150 rises to its original position by the elastic force accumulated in the return spring 144, and accordingly, the operating shaft 145 and the guide shaft 142 also rise.

The working shaft 145 is in contact with the pumping piston 141 while rising.

While the operating shaft 145 is in contact with the pumping piston 141 and ascends, the pumping piston 141 also rises.

When the pumping piston 141 rises, the opening/closing plate 143a rises by negative pressure generated in the intermediate storage chamber 115b, thereby opening the cylinder passage hole 115b.

When the cylinder passage hole 115b is opened, the contents of the storage container 120 flow into the intermediate storage chamber 115b through the cylinder passage hole 115b.

When the contents of the storage container unit 120 flow into the intermediate storage chamber 115b, the storage container unit 120 is deformed so that the internal space is reduced (see FIG. 20).

Due to the structure of the tube container, when the final discharge port of the contents (the end of the flow path formed on the button inclined surface) is facing the nozzle arrangement direction, the storage container body 121 can be held tightly, and accordingly, the button 150 is pressed with a finger. It becomes convenient to operate pressing. Here, the nozzle arrangement direction (see “B” in FIG. 1) means one of two directions perpendicular to the longitudinal direction (see “A” in FIG. 1) at the bottom of the storage container body 121.

However, according to the conventional pumping tube container, since there is no means for aligning the final discharge port of the contents (the end of the flow path formed on the button inclined surface) to the nozzle arrangement direction, the final discharge port of the contents (the end of the flow path formed on the button inclined surface) is There was a problem that there was a concern that it could deviate from the nozzle arrangement direction. If the final discharge port of the contents (the end of the flow path formed on the inclined surface of the button) is out of the nozzle arrangement direction, the pressing operation of the button 150 becomes inconvenient when in use, and the contents remaining in the discharge flow path during storage flow down (when the button is stored on the bottom surface) Inclination with respect to the direction perpendicular to the second problem occurs.

Next, when the pressing force on the button 50 is released, the button 50 rises to its original position by the elastic force accumulated in the return spring 44, and accordingly, the operating shaft 45 and the guide shaft 42 also rise.

As the actuating shaft 45 rises, it comes into contact with the pumping piston 41 and is closed between the actuating shaft passage 45b and the actuating shaft passage 45b.

While the operation shaft 45 is in contact with the pumping piston 41 and ascends, the pumping piston 41 also rises.

When the pumping piston 41 rises, the opening/closing plate 43a rises due to negative pressure generated in the intermediate storage chamber 15b, thereby opening the cylinder passage hole 15b.

When the cylinder passage hole (15b) is opened, the contents of the storage container part 20 flow into the intermediate storage chamber (15b) through the cylinder passage hole (15b) (see Fig. 15))

When the contents of the storage container part 20 flow into the intermediate storage chamber 15b, the storage container part 20 is deformed to reduce the internal space (see FIG. 16).

As described above, according to the embodiment of the present invention, it is formed by dividing the lower region of the male threaded portion of the storage container 20 and the inner cap 30 so that the inner cap 30 is screwed to the neck 22 Includes an inner cap locking portion 12 that blocks the bidirectional rotation of the cap 30, forms an inner cap fastening protrusion 32a on the outer surface of the inner cap 30, and seats the nozzle on the button guide wall portion 73 The inner cap fastening protrusion when the shoulder part 70 is coupled to the inner cap 30 so that the groove 73a is cut along the height direction from the top and the nozzle seating groove 73a is aligned with the nozzle placement direction B (32a) and the shoulder portion fastening groove (72a) that has a fastening action to form a cut in the inner surface of the shoulder portion (70), so that the side end of the button passage (side wall contact hole) is aligned with the nozzle seating groove (73a) By installing the button 50, the final discharge port (the end of the nozzle) of the contents can be aligned in the nozzle arrangement direction, and accordingly, the pressing operation of the button 50 becomes convenient when in use, and the contents remaining in the discharge passage during storage flow. It can be prevented from falling down (the button when stored, that is, the nozzle is placed in a direction perpendicular to the bottom surface).

And by forming the inner cap locking portion 12 to be aligned in the nozzle arrangement direction (B), when the shoulder portion 70 is coupled to the inner cap 30, the inner cap fastening protrusion 32a is inserted into the shoulder fastening groove 72a. ) Can be easily seated (when the nozzle seating groove is aligned with the inner cap locking part, the inner cap fastening protrusion is inserted into the shoulder fastening groove).

In addition, a cap contact hole 62a is formed through the cap side wall portion 62 and a cap alignment protrusion 62b is formed on the inner surface of the cap side wall portion 62 along the height direction, while the outer surface of the button 50 When the cap contact hole 62a is aligned with the side end of the button flow path, the button cap 60 having the button alignment groove 52b formed thereon so that it is aligned with the cap alignment protrusion 62b is coupled to the button 50, It is possible to reduce the external impact transmitted to 50), and the alignment of the cap contact hole 62a and the side wall contact hole 52a becomes easy. When the external impact transmitted to the button 50 by the button cap 60 is reduced, it is possible to stably maintain the coupling state between the vertical flow pipe part 53 and the guide shaft 42.
