Thereafter, when the user rotates the pipette device to release the screw connection with the container 10, the pipette assembly 20 forms the negative pressure in the compression space 41 while the bellows 40 is restored to the initial state And the contents stored in the container 10 are sucked into the pipette 22 by the negative pressure.

That is, in the process of separating the pipette device from the user, the contents stored in the container 10 are sucked and filled in the pipette device.

Next, when the user desires to discharge the sucked contents, the user presses the pump 80 and presses the button space 81 inside the pump 80 by the operation force applied from the user.

Here, the button space 81 of the button assembly 30 forms a closed space because the pump 80 is closely attached to the button mount 60. However, when the user presses the button space with the operation force of the user, The air in the button space 81 is discharged to the pipette assembly 20 side while the air in the button space 81 is deformed.

Therefore, when the pump 80 is pressed, the air in the button space 81 is moved to the pipette assembly 20 to discharge the contents stored in the pipette 22 by a predetermined amount.

The discharge diaphragm 74 is deformed only in the process of discharging the air, and after the air is discharged, the discharge diaphragm 74 is restored to the initial state by the elasticity of the material, thereby keeping the button space 81 in the closed state.

Particularly, even if the pressure applied by the user to the pump 80 is increased, the discharged air is limited, so that even if the user's operation force is increased, the amount of the discharged contents can be limited and the contents can be prevented from being wasted.

Next, when the user removes the operating force applied by the pump 80, the discharge diaphragm 74 keeps the discharge hole 65 in a closed state, so that air movement under the discharge diaphragm 74 is not generated It is possible to prevent the contents stored in the pipette 22 from being sucked back to the upper side.

Here, when the operation force applied to the pump 80 is removed, the shape of the pump 80 is restored to its initial shape, a negative pressure is formed in the button space 81, and the suction diaphragm 94 And external air is sucked into the button space 81 through the suction hole 67.

In the pipette device according to the present embodiment, a discharge passage for air is formed on the side of the pipette assembly 20 when the user presses the pump 80, and the button space 81 ), There is an effect that even when the pump 80 is repeatedly operated, only a predetermined amount of the contents is always discharged.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is to be understood that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
