Abstract (en)
[origin: EP1486261A1] The invention provides a pump unit and container wherein outflow of liquid is prevented while not in use during transport and the like, and deterioration in operability due to compression of bellows over a long period of time is also prevented. The pump unit of the present invention is inserted in a container main body Y and sucks out liquid in the container main body Y to the outside of the container main body Y, and is provided with: an intake pipe 63 inserted into the container main body Y; a bellows 64 capable of return movement in the direction of extension, and connected to an upper part of the intake pipe 63; and a piston part connected to an upper part of the bellows 64, which extends and contracts the bellows 64, and sucks out liquid in the container main body Y from a piston head P to the outside of the container main body Y via the intake pipe 63. Moreover, the piston part is able to be extended and contracted so that the piston head P can be stored on the container main body Y side the bellows 64 being contracted. <IMAGE>
