Abstract
A liquid container/dispenser including a container body defining a flexible wall for storing a liquid and a tube member having a first end portion placed outside the container body and a second closed end portion placed inside the container body. The tube member has an opening device provided in the second closed end portion of the tube member inside the container body. The second closed end portion can be broken off from the rest of the tube member inside the container body by a force applied through the wall of the container body. The wall of the container body is preferably made from a flexible material so that the wall can be flexibly brought into contact with the tube member inside the container. The liquid container with the novel dispensing system assures the sealed storage of liquid in the container and yet facilitates clean, quick and safe dispensing of the liquid.
