Abstract
The present application relates to a system for dispensing fluid. The system includes a flexible container including a spout that is in fluid communication with an interior region of the container. The system includes a cap configured to be mounted to the spout. The cap includes an opening that leads to a membrane and a first retention mechanism located in the opening. The system includes a piercing tube having a first end configured to puncture the membrane and a second end configured to be connected to a dispensing tube. The piercing tube includes a seal bead and a second retention mechanism. The piercing tube is inserted into the opening of the cap such that the first end punctures the membrane, the first and second retention mechanisms engage each other to retain the piercing tube in the cap, and the seal bead sealingly engages the cap.
