Abstract

PROBLEM TO BE SOLVED: To provide a cup-formed container with an opening reinforcing ring and a method of manufacturing the container wherein an operation of joining the opening reinforcing ring with a container body is easy and its quality is stable. SOLUTION: An annular fusion-bonding protrusion 221 having a flat fusing surface is provided on a lower surface of a flange 220 of the opening reinforcing ring 200. The opening reinforcing ring is inserted into an opening 130 inside an upper end of a barrel 110 of a container body 100 by inserting a peripheral wall 210 below the flange. Microcircular vibration energy is applied in a horizontal direction while pressing an upper surface of the ring by a horn 20, thereby fusion-bonding the annular protrusion 221 of the ring with a joining surface with an upper surface of an annular rolled portion 111 of the cup-formed container body. Then the flange lower surface of the ring is joined with the upper surface of the rolled portion of the container body.

Description of the Related Art Conventionally, cup-shaped containers made of a laminated material mainly composed of a paper layer have been widely used for alcoholic beverages, fruit juice drinks, etc. because of their characteristics such as light weight and easy disposability, but they have low strength and are difficult to distribute. In some cases, the lid was easily crushed during storage, and the lid was hard to be fixed with a stable and constant strength. For this reason, in order to impart strength to a cup-shaped container, for example,
There is a cup-shaped container with an opening reinforcing ring disclosed in Japanese Patent No. 24466. As shown in FIG. 3, the method of manufacturing the cup-shaped container with the opening reinforcing ring is a cup-shaped container main body (1) mainly composed of a paper layer and an innermost layer made of a laminated material of a synthetic resin layer.
00) is inserted into the anvil (30) (the cradle), and the annular winding portion at the upper end of the body is fixed from below to the body, and the opening (130) of the container is connected to the flange (220). A peripheral wall (210) having an annular fusion protrusion (211) having a vertical triangular cross-section and a linear fusion surface is inserted into the lower outer periphery, and an opening reinforcing ring (220) is inserted thereinto. Ultrasonic vibration energy is applied while inserting and pressing an inverted tapered horn (20) into the reinforcing ring, and the annular fusion protrusion (211) of the opening reinforcing ring and the body (110) of the cup-shaped container body. The joining surface with the inner surface was melted, and the peripheral wall (210) of the opening reinforcing ring was joined to the inner surface of the opening of the body (110) of the cup-shaped container body. Then, as shown in FIG. 2, the cup-shaped container (10) with the opening reinforcing ring is filled with the contents and used as a lid material (300) for sealing, as shown in FIG. (20
0) sealing by heat-sealing so as to be peelable on the upper surface, or
The cap was screwed or engaged with the opening reinforcing ring to seal.
