The present invention relates to a dispensing container, and more particularly, to a dispensing container for dispensing a liquid or a high-viscosity cream.

"Problems to be solved by conventional technology and invention" Conventionally, a container body with an upright mouth and neck and a vertical pump attached to the container with a mounting tube fitted to the mouth and neck are used. 2. Description of the Related Art There is known a dispensing container configured so that contents in a container body are sucked up from a cylinder at a lower end of a pump by vertically moving a lowering head, and are discharged from a nozzle hole of the lowering head.

In this type of container, a flexible bag is suspended in the container, the contents are filled in the container, and the bag is deformed so as to reduce its volume as the contents are discharged by the pump. It has been proposed to prevent the deterioration of the contents and the contamination of various contents with the contents by minimizing the contact between the contents and the air as much as possible.
No. 63-77989 (Japanese Utility Model No. 2-1684).

However, although the above-mentioned conventional one exerts a remarkable effect to achieve the above-mentioned object, it has some problems in workability in filling the contents.

That is, the container has an upper end fitted to the container body neck and neck, and a bag mounting cylinder having upper and lower end faces opened with the lower end hanging down into the container body, and the bag edge is brought into close contact with the outer surface of the cylinder to form a bag. Although the mouth is closed and hung inside the container, when filling the contents, expand the bag by gas injection or the like, or reduce the volume of the bag as much as possible by reducing the pressure to reduce the volume of the good contents. There is a problem that filling cannot be performed. In particular, when the content is a cream-like material having a high viscosity, the tendency is remarkable, and if the above pretreatment is not performed, air is mixed into the content, which becomes bubbles and is contained in the content. The problem of mixing exists.

An object of the present invention is to provide a dispensing container which has solved the above-mentioned disadvantages of the prior art.
