Abstract:
A crimp tube having a sealed throat opening at one end and an open end crimped close at an opposite end is provided with an internal stiffener which is resilient and will return to its original shape upon release of pressure. The stiffener is generally cylindrical and has generally radial openings therethrough communicating to the space between the outer diameter of the stiffener and the inner diameter of the tube to allow contents to flow to the interior of the stiffener and from the interior of the stiffener to the area between the stiffener and the inner diameter of the tube. The tube being formed of soft material is collapsible against the stiffener and further collapsible with the stiffener to dispense materials from the tube subsequent to opening the closure at the throat. On release of pressure the stiffener will return to its uncompressed condition.
