The unexplained code 99 is a check valve.

Next, the operation and effects of the pump dispenser for containers of the present invention configured as described above will be described.

First, when the push button 210 is pressed in the vertical direction to discharge the contents in the container, the opening and closing member 240 and the inner housing 280 connected to the lower part of the push button 210 are simultaneously lowered.

The seal cap 270 coupled to the outer periphery of the inner housing 280 descends along the inner periphery of the outer housing 300. The inner housing 280 descends first and the seal cap 270 descends later.

In this way, since the inner housing 280 is lowered before the seal cap 270, the seal cap 270, which was in close contact with the upper outer circumference of the inner housing 280, is spaced apart, thereby opening the plurality of holes 282.

As the inner housing 280 and the seal cap 270 descend, the volume within the inner housing 300 decreases. As this volume decreases, the check valve 99 inserted into the lower inner periphery of the external housing 300 opens and the contents flow into the external housing 300.

The liquid content flowing into the external housing 300 flows through the hole 282 and is discharged through the discharge port 211 of the push button 210.

When the push button 210 stops pressing, the inner housing 280 is raised by expansion of the second spring 290. As the internal housing 280 rises in this way, the seal cap 270 also rises.

In this state, when carrying this container without using it, the push button 210 must be lowered and immediately brought into close contact with the upper surface of the shoulder member 220 to prevent the contents from being discharged. In this way, the push button 210 ), when locking the push button 210 by hand and rotating it in the closing direction, the inner seating protrusion 261a of the locking control member 260 that was hanging on the lower surface of the opening and closing protrusion 241 of the opening and closing member 240 When it moves toward the lifting groove 261b, the push button 210 is pressed downward, and the opening and closing member 240 descends along the lifting groove 262 of the locking control member 260. After descending to a certain extent, when the push button 210 is rotated in the closing direction, the step groove 242 of the opening and closing projection 241 is seated on the lower surface of the inner seating projection 261a of the locking control member 260 and does not rise. It becomes a state of no.

Conversely, when unlocking, when the push button 210 is turned in the open direction, the opening and closing protrusion 241 is located in the lifting groove 261b of the lock control member 260, and the first spring 250 expands to open the push button. By raising (210), a pump dispenser is used.

A cylindrical stone tongue 232 is inserted into the space between the inner circumferential wall 261 and the outer circumferential wall 262 so that the outer circumferential wall 262 is in close contact with the inner circumference of the outer housing 300 to prevent the external liquid, that is, water. It blocks the etc. from flowing into the container.

In addition, a plurality of square protrusions 232a protruding at regular intervals at the lower end of the cylindrical protrusion 232 of the chaplet 230 are inserted into the plurality of slots 263a formed in the locking control member 260.

Air is allowed to flow into the container through a gap between the slot 263a and the square protrusion 232a.

Additionally, a hole 223 is formed on the upper surface of the shoulder member 220 to allow external water to be discharged out of the container.

As above, although specific embodiments have been described in the detailed description of the present invention, it is obvious that the technology of the present invention can be easily modified and implemented by those skilled in the art, and such modified embodiments are included in the claims of the present invention.
