されている。 The body member 1 of the container consists of a cylindrical body member 20 and a cylindrical reinforcing member 30. The cylindrical body member 20 is formed into a reverse tapered shape using a well-known cup forming machine, and has an outwardly curled edge portion 21 formed at its upper end, and a bottom member 22 is joined to its lower end. ing. The cylindrical body member 20 is also made of an elastic composite material having at least a paper layer and a thermoplastic synthetic resin layer on the inner wall side, such as thermoplastic synthetic resin a, aluminum foil b, thermoplastic synthetic resin c , paper d, and thermoplastic synthetic resin e are laminated in this order. On the other hand, the cylindrical reinforcing member 30 is formed in the same reverse tapered shape as the cylindrical body member 20, and has a flange portion 31 integrally formed on its outer edge. The cylindrical reinforcing member 30 is also formed by, for example, injection molding using a relatively elastic thermoplastic synthetic resin.

混入するのを防止できる。 The body member 1 of the container consisting of the above has a cylindrical body member 2.
Since the upper end of the cylindrical body member 20 is reinforced by the cylindrical reinforcing member 30 joined to the inner wall of the cylindrical body member 20, it is extremely resistant to crushing. Furthermore, since the cylindrical reinforcing member 30 is joined to the inner wall of the cylindrical body member 20, the appearance of the body 1 of the container does not deteriorate, and the cylindrical body member 20 of the cylindrical reinforcing member 30 does not deteriorate.
Since it is possible to arbitrarily select the bonding area for the bonding area, it has the advantage that the bonding strength can be adjusted.
Further, since the flange portion 31 is integrally formed, the cover member 24 can be stably joined to the flange portion 31, and the end edge portion 21 can be covered by the flange portion 31. Therefore, paper powder that may adhere to the edge portion 21 can be prevented from entering the container.

A cylindrical reinforcing member 3 that also has a reverse tapered shape with respect to 0
0 is fitted, and the outer wall of the cylindrical reinforcing portion 30 is in relatively close contact with the inner wall of the cylindrical body member 20. While vibrating and inserting the reversely tapered horn 40 into the cylindrical reinforcing member 30 in the fitted state as described above, the cylindrical reinforcing member 30 is pressed against the cylindrical body member 20. When ultrasonic vibration energy is applied to the horn 40 by a well-known means described later, the inner wall of the cylindrical body member 20 and the outer wall of the cylindrical reinforcing member 30 are firmly joined by so-called shear welding. After that, if the horn 40 is raised while vibrating, it can be easily pulled out from the body member 1 since the friction is small.

The horn 40 can be inserted smoothly.
By inserting this, the cylindrical reinforcing member 30 can be pressed against the cylindrical body member 20, and a means for applying pressure between the joining members necessary for the ultrasonic welding method can be easily obtained.

することができる。 Further, in the method of the present invention, the cylindrical body member 20 and the cylindrical reinforcing member 30 are shear-welded as the horn 40 vibrates in the vertical direction, that is, the cylindrical body member 20
Since the cylindrical reinforcing member 30 is welded by frictional heat caused by being displaced parallel to the cylindrical body member 2,
It is possible to prevent air bubbles from being mixed in at the interface between 0 and the cylindrical reinforcing member 30, and a highly airtight joint can be achieved.

Since the cylindrical reinforcing member 30 and the cylindrical reinforcing member 30 are each made of an elastic material, there is a buffering effect when the horn 40 is inserted, the horn 40 is not damaged, and each can be brought into close contact with each other. Further, in the present invention, by having the above structure, the inner wall of the cylindrical body member 20 and the cylindrical reinforcing member 30
It has become possible to use crystalline resins such as polyethylene and polypropylene, which were previously thought to be unsuitable for shear welding due to their significant attenuation of ultrasonic vibration energy, as thermoplastic synthetic resins for forming the This is also one of the advantages.

Forming a cylindrical body member using a composite material consisting of at least a paper layer and a thermoplastic synthetic resin layer so that the thermoplastic synthetic resin layer serves as an inner wall,
A cylindrical reinforcing member made of thermoplastic synthetic resin has a flange on the outer edge and only the inner wall is inverted tapered.
After fitting the cylindrical reinforcing member to the edge of the cylindrical body member and surrounding the edge of the cylindrical body member with the flange portion, a reversely tapered horn is attached to the cylindrical reinforcing member. While inserting, pressing the cylindrical reinforcing member against the cylindrical body member and applying ultrasonic vibration energy to the horn,
A method for manufacturing a container body member, comprising joining an inner wall of the cylindrical body member and an outer wall of the cylindrical reinforcing member.
