Claims

[Scope of utility model registration request]

It has triangular panels on both sides, folding pieces and front and rear panels at both oblique sides of the triangular panels,
This is a device that hermetically seals the bottom of a paper container, which has a bottom structure with a sealing part formed by folding folded pieces from both sides between the front and rear panels and folding back the polymerized part. A groove having a matching outer circumferential shape and a surface in contact with the bottom of the container is provided with a groove of approximately the same size and shape at the position of the sealing part of the container so as to rise in a stepped manner from the outside to the center; A mandrel head having a protrusion along the concave groove at the end perpendicular to the longitudinal direction of the groove, and a surface opposite to the mandrel head that has a larger outer circumference due to the shape of the container and is in contact with the bottom of the container. is highest at the position where it abuts both sides of the sealing part of the container, followed by the position excluding the triangular panel part, the position where it abuts against the central part of the sealing part of the container and the part including the triangular panel part, and then lower in a stepwise manner. A sealing device for sealing the bottom of a paper container with a press pad.
