Japanese Patent Laid-Open No. 7-172466

  The liquid storage bag disclosed in Patent Document 1 is made into a cylindrical shape by blow molding or the like using a synthetic resin material, and the inside of the liquid storage bag is depressurized by the vertical movement of the pump member. When the bag is thin, the bag is deformed in a wrinkled state so that the bag is in close contact with the tube due to the reduced pressure inside the bag, and the liquid inside the bag is almost extracted from the nozzle of the pump member. However, if the bag is thick, there is a problem that even if the inside of the liquid storage bag is depressurized by the vertical movement of the pump member, the bag is not easily deformed and the liquid tends to remain at the bottom of the bag.

  Therefore, in order to remove almost no liquid inside the bag from the nozzle of the pump member by moving the pump member up and down, the bag thickness can be reduced, but if the bag thickness is reduced, the shape of the bottom part of the bag can be simplified. In order to stabilize the shape of the top and bottom of the bag, a synthetic resin ring member may be provided at the upper end and an inverted dish-shaped bottom member made of synthetic resin may be provided at the lower end. A liquid storage bag having such a ring member and a bottom member and containing liquid therein, a so-called cartridge is put in a container, and the liquid inside the cartridge is extracted from the nozzle of the pump member by the vertical movement of the pump member. In a state where the liquid inside the cartridge is used up, the cartridge (bag) film is deformed in a state where the wrinkles are contracted so that the film of the cartridge (bag) is brought into close contact with the tube.

  As described above, when a cartridge having a ring member at the upper end and a bottom member at the lower end and a cartridge bag made of a thin and easily deformable film is used, liquid is extracted and the pump member is removed from the used up cartridge. When the tube is pulled out, there is a problem that it takes time to pull out the tube of the pump member from the cartridge because the film of the cartridge is in close contact with the tube.

  An object of the present invention is to solve such a problem. A cartridge for storing a liquid is placed in a container, a liquid suction tube of the pump member is pierced, and the liquid is discharged by an up-and-down operation of the pump member. An object of the present invention is to provide a liquid dispensing device that can easily pull out a tube of a pump member from a cartridge.

  In the liquid dispensing apparatus according to claim 1 of the present invention, the cartridge in which the liquid is stored is placed in the container, and the liquid suction tube of the pump member attached to the upper end of the container is pierced into the upper end of the cartridge. In the liquid dispensing apparatus for dispensing liquid by the vertical movement of the pump member, the container has a cylindrical inner container body closed with a lower end closed so as to store the cartridge, and is covered from the upper end of the inner container body. The inner container body includes an outer container body formed on the inner surface with a female thread portion that engages with the outer thread portion of the outer container body, and the pump member is attached to the upper end opening of the outer container body, and the liquid suction of the pump member The tube is configured to pierce the upper end of the cartridge housed in the inner container body, and the cartridge includes a bottom member at the lower end, a ring member at the upper end, The upper and lower ends are joined to the ring member and the bottom member, and a barrel portion is formed so as to be cylindrical with a flexible film made of a material including a synthetic resin film.
