ABSTRACT:
A thumb actuated flexible tube and closure system comprising a flexible plastic tube having a finish for dispensing a product when the tube is in an inverted position. The finish has an integral transverse wall, an integral post extending upwardly from the transverse wall and an integral cylindrical wall extending upwardly from said transverse wall. The transverse wall has at least one opening therethrough. An inner closure is provided and has a base wall and integral spaced inner and outer walls defining an annular space for receiving the finish of the plastic tube. At least one of the walls has threads thereon for rotatably engaging the finish. The base wall of the inner closure has a portion sealingly engaging the post on the finish such that rotation of the inner closure moves said sealing portion into and out of engagement with said post. An overcap closure is provided and has a base wall with an opening aligned with the sealing portion of said closure. The overcap and finish have interengaging elements to hold the overcap against rotational movement. The overcap includes a peripheral wall having an opening therein. A finger engaging portion on the inner closure extends through the opening in the overcap closure adapted to be engaged by a thumb of the user as the plastic tube is held in inverted position to rotate the inner closure and move the inner closure into and out of sealing position with the post on the finish.
