Title: Blown tube container
Inventor: SATO TATSUO
IPC: B65D35/14
Filed: 1995-06-16
Abstract: PURPOSE: To surely squeeze out content at an extremity end nozzle of a final stage of use of a container by a method wherein a main body of a blown tube is made such that only the inner-most raw material layer is peeled off an adjoining layer located outside the material in response to a repetitive pressing and recovering of the blown tube main body and then a content storing part is combined with the adjoining layer so as to be shrinked. CONSTITUTION: An outer wall of a blown tube main body 1 is depressed, a required amount of its content is taken out through a valve mechanism 2 and a nozzle 3. As the depressing force is released, a returning side passage of the valve mechanism is closed. In addition, the blown tube main body 1 is returned back to its original state while sucking surrounding air through an air inlet hole 6 formed at a proper location with a recovering force of the raw material. The surrounding air sucked through the air inlet hole 6 enters a gap between the inner-most second modified polyethylene 10d having no adhesion characteristic of the blown tube main body 1 and a thermoplastic resin 10c of the outer adjoining layer so as to cause both of them to be easily peeled off from each other.  Repetition of this action may cause the content storing part 4 to be gradually decreased in size and the content can be completely taken out of the container.
