Liquid dispensing system

A liquid dispenser comprising:

• a container body for storing a liquid, the container body defining a wall;
• a tube member having a first end portion placed outside the container body and a second closed end portion placed inside the container body;
• and
• an opening device provided in the second closed end portion of the tube member inside the container body for opening the second closed end portion by a bending force applied through the wall of the container body;
• and wherein
• the opening device comprises a snap-off score formed in the tube member adjacent the second closed end portion thereof for snapping off the second closed end portion inside the container body to allow the liquid to communicate with the first end portion;
• the container body is made from a pliant material for allowing the container body to flexibly deform and the tube member is made from a relatively hard material to facilitate breaking-off of the second closed end portion of the tube member at the snap-off score when the container body and the tube member inside the container body are bent about the snap-off score;
• and the container body has a top portion defining an aperture for sealingly coupling the tube member and a bottom portion opposite the top portion, the bottom portion having a thickness substantially thinner than that of the top portion of the container body to facilitate bending of the wail of the container body, and the tube member has a portion inside the container body extending to the bottom portion of the container body so that the closed end portion of the tube member is placed adjacent the bottom portion of the container body.

A method of dispensing liquid from a container defining a wall, the method comprising the steps of:

• sealingly connecting a tube member to the container, the tube member having an open end portion to be placed outside the container and a closed end portion to be placed inside the container;
• bringing the wall to come in contact with the tube member inside the container;
• and
• applying a force to the tube through the wall to open the closed end portion to allow liquid within the container to communicate with the open end portion of the tube member;
• and wherein
• the container has a relatively thick portion for storing substantially an entire volume of the liquid and a relatively thin portion thinner than the thick portion adjacent the closed end portion, the method further comprising the steps of moving substantially the entire volume of the liquid into the relatively thick portion, and removing the closed end portion.
