Description of the Related Art In a liquid container including a container body and a nozzle portion, for example, a liquid container such as an enema container, it is desired that the discharged liquid does not flow backward when the liquid in the container body is discharged. In such a case, as a liquid backflow prevention method, a method in which a spherical backflow prevention valve is attached to the nozzle portion has been proposed (see Japanese Utility Model Laid-Open No. 55-166242). In addition, the container body is a pentagonal pyramid-shaped container, and two fold sides that face each other among the four side surfaces and a fold line that facilitates folding are provided in advance, and the container body is crushed along the fold line. It has also been proposed to discharge the liquid and prevent the container from returning to its original shape after the discharge (see Japanese Patent Laid-Open No. 61-213060).
