11 is a cross-sectional view of a bypass channel and a charge pump according to an embodiment of the present invention.

Referring to FIG. 11 , the bypass channels 440 and 450 connect the container part 100 and the upper wall of the filling chamber 210 to the container part 100 generated during upward movement of the filling piston 220 . an upper bypass channel 440 to relieve negative pressure; and a lower bypass channel 450 connecting the container part 100 and the lower wall of the filling chamber 210 and relieving positive pressure in the filling chamber 210 generated during the downward movement of the filling piston 220 . have.

In an embodiment, the upper bypass channel 440 may communicate with the top of the filling chamber 210 . Accordingly, while the charging piston 220 is positioned in the first region or ascends from the first region to the second region, it is not closed by the seal cap 222 and may maintain an open state. Through the upper bypass channel 440 , the container part 100 may communicate with the upper region of the charging piston 220 (in particular, the upper region of the seal cap 222 ) in the charging chamber 210 . When the contents in the container part 100 are introduced into the filling chamber 210 due to the rise of the filling piston 220 , a negative pressure is generated in the filling chamber 210 , which may inhibit the inflow of the contents. However, by communicating with the container unit 100 by the upper bypass channel 440 , the negative pressure is relieved, and the contents can be smoothly moved.

In an embodiment, when the filling piston 220 is positioned in the second region, the upper bypass channel 440 may be closed by the filling piston 220 . Specifically, the upper communication hole of the charging chamber 210 connected to the upper bypass channel 440 is closed by the seal cap 222 of the charging piston 220 , and the container part 100 and the upper end of the charging piston 220 are closed. Communication with the area may be blocked. By blocking, the contents in the container part 100 may be prevented from leaking toward the filling chamber 210 .

In an embodiment, the lower bypass channel 450 may maintain a closed state while the charging piston 220 is positioned in the second region or descends from the second region to the first region. Specifically, the lower communication hole of the charging chamber 210 connected to the upper bypass channel 450 is closed by the seal cap 222 of the charging piston 220 , and the lower end of the container part 100 and the charging piston 220 . Communication between the region (in particular, the lower region of the seal cap 222 or the content filling region) and the container unit 100 may be blocked. By blocking, the contents in the container 100 may be prevented from leaking into the filling chamber 210 , or the contents in the filling chamber 210 may be prevented from leaking into the container part 100 .

In an embodiment, a positive pressure is generated in the filling chamber 210 by the lowering of the filling piston 220 , and the positive pressure may move the contents into the pressure chamber 310 . If the descent continues, a large positive pressure is generated in a relatively narrow content filling area, which makes it difficult to lower the charging piston 220 or causes the charging piston 220 to rise too quickly when the trigger 700 is released. Problems can arise. To solve this, the lower bypass channel 450 may be opened when the charging piston 220 continues to descend to reach the first region. As the filling chamber 210 communicates with the container part 100 by opening the lower bypass channel 450 , the positive pressure may be relieved.

In an embodiment, an opening protrusion 211 may be formed on the bottom surface of the filling chamber 210 to open the lower bypass channel 450 toward the filling piston 220 , in particular, the seal cap 222 . When the filling piston 220 descends to the first position, the opening protrusion 211 separates at least a portion of the seal cap 222 that is in close contact with the filling chamber 210 from the filling chamber 210 (ie, releases the close contact). ), the filling chamber 210 may communicate with the lower communication hole and the lower bypass channel 450 through the separation space.

The bypass channels 440 and 450 and the charge pump 200 shown in FIG. 11 are exemplary, and various configurations may be applied according to an embodiment to which the present invention is applied.
