  Since the above-mentioned full open type sealed insulated double can seals the inner container with a full open canopy, when the full open canopy is opened and removed, the inner container opens and hot water can be poured directly into the inner container. In addition, because the heat insulation space is formed between the walls of the inner and outer containers, when the hot water is poured into the inner container in the can after opening, the can body does not become hot, Excellent in properties. However, since the flange part of the inner container and the full-open canopy are closely polymerized, when opening the full-open canopy, when the tab of the full-open canopy is caused, the tip of the tab is placed on the flange part of the inner container. It has a drawback that it is abutted and hardly causes a tab.

  Furthermore, the welded can body, the inner container and the full open canopy are tightened in triplicate. However, the force required for the tightening is increased and the canned product may be crushed. However, if the force required for tightening is weakened, there is a possibility that perfect sealing cannot be obtained.

  The present invention improves the above-described full-open type sealed heat insulation double can without losing the convenience of the above-mentioned full open type heat insulation double can, so that it is easy to open and no imperfect sealing can occur. The object is to obtain canned food containers and a method for producing the same.

  In order to solve the above-mentioned problems, the present invention is a canned container in which a cup-shaped container containing instant food is sealed, and is divided by the score line by breaking the score line at one can barrel end. A full-open can lid that can open a portion is mounted, and a recess recessed inward is formed in the vicinity of the end of the can barrel to which the full-open can lid is mounted, and is in close contact with the inner surface of the can barrel; A ring secured to the can barrel end side by the recess is locked or fixed inside the can barrel, and a container containing dried food is attached to the other can barrel end of the ring and the can barrel. A can with an instant food container, the open end of the container being in contact with the ring and the inner surface of the can body and the lower end of the container being in contact with the inner surface of the bottom cover It is.

  Furthermore, the present invention is a method for producing a canned container in which a cup-shaped container containing instant food is sealed, wherein a recess recessed inward is formed near one end of the can body, and the recess is formed. A can opening opposite to the one end side of the recess is attached to the end of the can body by attaching a full-open can lid that can open the portion defined by the score line by breaking the score line. After contacting the body side and the inner surface of the can body and locking or fixing the flexible ring, the container containing the dried food is inserted into the can body, and the open end of the container containing the dried food is Place the container containing dry food in contact with the can barrel side portion of the ring and the inner surface of the can barrel inside the can barrel, and then reverse the can barrel and attach a bottom lid to the end of the can barrel The lower end of the container containing the dried food against the inner surface of the bottom lid attached to the end of the can body By a bottom cover and the ring and in instant food containers canned manufacturing method of securing a container containing a dry food against canned axis and canned radial direction in canning.
