Title:
INTERNAL PRESSURE ADJUSTABLE TUBE CONTAINER
Document Type and Number:
Japanese Patent JP2012236645
Kind Code:
A
Abstract:

To provide a tube container which prevents a cap from being made difficult to open and close because content liquid leaking out until closing the cap after squeezing the content liquid having such a property as to be solidified when being brought into contact with air is attached to the surrounding of a takeout port and is solidified.

The content liquid leaks out because the internal pressure is made high as it is by pushing a belly part 4 of a tube and, therefore, the leaking-out can be prevented by returning the depressed belly part into the original state to lower the pressure. Therefore, a circular spring 3 made by reversely joining together upper and lower two sheets of semicircular steel sheets each of which is expanded in accordance with the roundness of the tube and has elasticity and combining the steel sheets with hinges is fitted into the tube on the position where the belly part of the tube and upper and lower expanded parts of the spring, and a back part 5 of the tube and right and left both end parts respectively match with each other. Thereby, when the belly part of the tube is pushed to put out the content liquid and, thereafter, the back part is pushed, the bulge which is depressed is returned owing to the property of circularity when the back part is pushed, as the result, the internal pressure is lowered to prevent the excessive liquid from leaking out to solidify the drawing-out port.
