た。(Problem to be solved by the invention) However, in such containers, the lid is directly wrapped around the open end of the container body. Not only does the sealing of the container become unreliable because cracks tend to occur in the container, but there is also the problem that the lid separates from the container body, especially when pressure is generated in the container, such as for carbonated beverages.

付けた。(Example) The following description will be made based on drawings showing an example of the implementation of the present invention. Reference numeral 1 indicates a container body, and the body 1 is made of a laminated sheet having a paper substrate and thermoplastic resin layers 3 on the surface thereof. A thin flexible cylinder 4 made of a thermoplastic resin such as polypropylene or polyethylene was attached to the end thereof.

蓋体６は容器胴体１に固定されている。 The cylindrical body 4 is fixed with an adhesive 7 by fitting an axial groove 5 provided in a mounting portion 4a protruding from the lower part into the open end of the body 1. In order to ensure firmness, the groove 5 is provided with a chevron-shaped protrusion 5a on one side wall thereof, and a concave portion 5b facing the protrusion 5a on the other side, which is fitted into the groove 5. The open end of the body 1 is pressed by the mounting portion 4a to form a bent portion 1a that is pressed by the protruding portion 5a and engaged in the recessed portion 5b. Reference numeral 6 denotes a lid, and the lid 6 is made of a thin metal plate and is formed into a dish shape with a flange 6a.The lid 6 is fixed to the container body 1 by tightening the flange 6a together with the cylinder 4. ing.

る。(Effects of the invention) As described above, according to the invention, a thin cylinder 4 made of flexible thermoplastic resin is adhered to the end of the container body 1 made of a laminated sheet with paper as a substrate. Since the metal lid body 6 is seamed to the cylinder body 4, even if the container body 1 has low ductility, stress cracks will not occur due to the seaming of the lid body 6, and the lid body 6, the cylindrical body 4 has a thick mounting part 4a extended at its base, and an axial ring-shaped groove 5 is provided in the mounting part 4a. By providing the protruding portion 5a and the recessed portion 5b on both sides of the container body 1, this portion
is subjected to a particularly strong pressure contact force, and has the effect of providing high bonding strength and adhesive strength. Moreover, since the cylindrical body 4 is connected simply by fitting the container body 1 into the groove 5, the assembly work is simple and the productivity is high.
