[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cream discharge container.

[0002]

2. Description of the Related Art Generally, a cream-like container is provided with a cream.
The upper surface of the container body containing the rubber-like material is closed with a cap. When removing the cream-like material, the cream-like material is removed by attaching it to the finger except for the cap. In order to remove such defects, a pump device with an elastic dome-shaped member is attached to the opening of the container body, and the compression operation of the elastic dome-shaped member and the elastic restoration restore the container. 2. Description of the Related Art There is known a container capable of discharging a cream-like material in a body from a nozzle.

[0003]

In the above-mentioned conventional container with a pump device, the dome-shaped member and the nozzle are both provided on the upper surface side of the container. Therefore, when the container is miniaturized, the nozzle interferes with the operation of compressing the dome-shaped member. In addition, there is a limit to downsizing to maintain the restoring force of the member,
Therefore, it is not suitable for a small cream-shaped material discharge container.

According to the present invention, the dome-shaped member is replaced with a cylinder and a piston which is urged by a spring and slides in the cylinder, and the cylinder is protruded to the side of the upper portion of the container to be fitted into the cylinder. The operation of the operating member with a piston is performed on the side of the container so as not to hinder the removal of the cream-like material from the discharge port opened toward the upper surface of the container.
