Abstract

Disclosed is a tubular paper container with position limiting function and a mould structure of the container, in particular to a innovative design which can avoid the disadvantages of lacking of position limiting, fixation, and easy dropping off on the widely-known tubular paper container whose tube cover and cover junction are made by lining paper tube protruding out of the opening. A molding pole with a big pole end at the top is hitched in a two-stage hole in a lower mould base; a transverse incision groove is provided for one end of an ejecting force part whose other end is a bevel edge top to be pivoted; an elastic piece is up pushed with micro warp under normal condition and is aligned with the outer diameter of the big pole end. After the lining paper tube is hitched to the big pole end, the lower end of a mould pole matched with a upper mould body is hitched in the lining paper tube and the ejecting force part is pressed down, the inner wall of the lining paper tube will be propped up outside by the bevel edge top of the ejecting force part. The upper mould base driving the lining paper tube to rotate will force the bevel edge top to scratch a blocking flange on the lining paper tube, combining the lining paper tube with the inner wall of the tubular paper container and making the blocking flange protrude outside the opening will provide a blocking and position limiting when offering tube cover and cover junction, thus avoiding falling off and resulting in a better covering effect.
