Abstract
This invention relates to a container for feeding a bar shaped article such as an erasing gum, a pencil lead, a crayon, a pastel, or an eyebrow stick, especially for advancing or retracting the bar shaped article. A bar shaped article (8) is inserted into an inner sleeve (2) from the rear end with the outer sleeve (1) being held by the hand, then the rear end of the inner sleeve (2) is pressed. Inner sleeve (2) moves forward and rearward against the resilient force of an elastic biasing member (3). A chuck (4) at the end of the inner sleeve (2) opens and closes repeatedly and the end of the bar shaped article (8) is fed out and can be used. When the chuck (4) holds the bar shaped article (8) in an unused state a chuck open means opens the chuck 4 slightly and loosens the securing force preventing encroachment of the chuck (4) into the article (8) allowing the chuck (4) to easily separate from the article (8) when the article (8) is fed out. Therefore feeding of the article (8) is performed accurately and smoothly.
