Liquid container
First Claim
1. A method of manufacturing a liquid container for storing liquid to be supplied to a liquid consuming apparatus, the method comprising:
- a case member providing step of providing a case member formed with a liquid reservoir chamber into which the liquid is to be filled,wherein the case member includes a liquid injection port for injecting the liquid into an inside of the case member, a liquid injection passage communicating the liquid injection port with the liquid reservoir chamber, and a liquid delivery port communicating with the liquid reservoir chamber for delivering the liquid from the liquid container to the liquid consuming apparatus,wherein a partition wall for closing the liquid injection passage is provided in a liquid flow passage, wherein a part of a wall surface forming the liquid reservoir chamber and a part of a wall surface forming the liquid injection passage are constructed by a flexible film, andwherein the flexible film is provided over a top surface of the partition wall but is not attached to the top surface of the partition wall;
a liquid injection step of injecting the liquid from the liquid injection port into the liquid injection passage so that the liquid flows into an inside of the liquid reservoir chamber through a clearance formed between the top surface of the partition wall and the flexible film; and
a passage closing step of closing a flow passage of the liquid by attaching the flexible film onto the top surface of the partition wall after the injection of the liquid into the inside of the liquid reservoir chamber is complete.

Abstract
The invention provides a liquid container for storing liquid to be supplied to a liquid consuming apparatus. The liquid container is constructed such that pressurized fluid is sent to its inside so that the liquid in the inside is delivered to the outside. The liquid container includes a container body which stores the liquid in its inside. The container body includes a pressurized fluid introduction port for introducing the pressurized fluid to the inside and a liquid delivery port for delivering the liquid to the outside. A detection unit is provided in the container body and outputs an output signal which is changed in accordance with a change in pressure of the liquid in the inside of the container body.
