Description

  In the present invention, a score is formed on the entire inner periphery of the canopy wound around the mouth of the can body, a part of the score is torn by operating a pull tab provided on the canopy, and the score is torn along the score. It relates to a full-open type sealed can that is opened and opened. Specifically, it is a container with a bottom that contains as a content a water-cooked food or hot-water cooked food that can be eaten only by pouring drinking water or hot water. And forming a heat-insulating space by a double structure consisting of a bottomed outer container for accommodating the inner container, and performing gas treatment by nitrogen gas replacement or bagging an oxygen scavenger to package the contents hermetically. The present invention relates to a full-open sealed insulated double can for instant food. In addition, it relates to instant foods for storage with a canned food that can be eaten only by pouring drinking water or hot water, and canned food, and canned food with a heat insulation structure in the can body. The present invention relates to an instant food for storage in which a sealed cooked double canister is filled with a hydrated cooked food or hot water cooked food. Note that “can” refers to a metal can, and “can” is synonymous with “making iron” or “making iron”.

Conventionally, as seen in canned foods, soup cans, ground coffee cans, and the like, canning techniques relating to full-open type and pull-top type sealed cans are known (see, for example, Patent Documents 1, 2, and 3). ). Here, it does not matter whether it is a welded can or an aluminum can (deep drawn can).

In addition, there are many proposals for a heat insulating container having a can body having a double structure as seen in cup containers for instant foods such as noodles and miso soup. Here, a sealing lid in which a resin-coated aluminum sheet is heat-sealed on a resin can body is mostly, and the entire container is packaged with an exterior film. This type of insulated container is a sealed container, but has a shelf life of several years, and shape retention (rigidity) that can withstand harsh transportation as a relief item for disaster and food-prone areas (See, for example, Patent Documents 4, 5, 6, and 7).

Under such circumstances, there has been a proposal of instant foods for preservation in a canned form with improved preservation for disaster storage (see, for example, Patent Document 8). However, in this known example, only a heat insulating material (for example, styrofoam) is wound around the outer periphery of canned instant food, and heat transfer (heating) of the mouth is not considered when hot water is injected. Inferred. When eating, it will be hot and you won't be able to speak immediately. Moreover, the problem that a heat insulating material will be damaged if it handles severely is also assumed.
Japanese Patent Laid-Open No. 10-23872

  The inventor has been engaged in the production of welded cans for a long time. In recent years, instant foods (especially drinking water or hot water only) have been used as canned foods for disaster support that take advantage of the characteristics (especially rigidity) of welded cans. The development of a fully-open sealed hermetic can for instant foods with the contents of edible cooked food or hot water cooked food that can be eaten in the field) has been completed and the present invention has been completed.

  The problem to be solved is to construct a sealed insulated can for stored foods using a welded can. The target effect is to ensure long-term storage (including sealing) and shape retention (including impact resistance based on high rigidity and transportability by loading packaging) by taking advantage of the characteristics of welded cans. It is.

  A specific technical solution is to form a fully-open sealed hermetically sealed double can for instant foods that contains water or hot water cooked food that can be eaten only by pouring drinking water or hot water, and the packaged food. Can be provided as an instant food for storage.

  The present invention has been made in view of such circumstances, and solves the above-described problems, and is insulated by a double structure comprising a bottomed inner container for storing contents and a bottomed outer container for storing the inner container. A full open type sealed insulated double can for instant food that forms a space and hermetically wraps the contents, and a hydrated cooked food or hot water cooked food is enclosed as the contents in the sealed insulated double can Providing instant food for preservation.

In order to solve the problem, the present invention forms a score on the entire inner periphery of the canopy wound around the mouth of the can body, tears a part of the score by operating a pull tab provided on the canopy, and In a full-open type sealed can that was torn along the score and opened.
A heat insulation space is formed by a double structure consisting of a bottomed inner container that contains as a content water-cooked food or hot water cooked food that can be eaten by simply pouring drinking water or hot water, and a bottomed outer container that contains the inner container. A full open type sealed insulated double can for instant food that has been subjected to gas treatment by nitrogen gas replacement or bagged with an oxygen scavenger to seal the contents,
A fully open canopy with a score on the lid and a pull tab attached;
A bottomed inner container integrally formed of a heat-resistant resin material in a cup shape;
It has a bottomed outer container consisting of a welded can that is formed in a cylindrical shape by double winding a can body member and a can bottom member,
While maintaining a space between the walls of the bottomed inner and outer containers to form a heat insulating space, the bottomed inner and outer containers and each flange portion of the canopy are closely polymerized, and triple-tightened,
The score of the fully open canopy is formed so that the opening diameter at the time of opening the lid is larger than the inner diameter of the mouth portion of the bottomed inner container and smaller than the inner diameter of the mouth portion of the bottomed outer container. It is characterized by.

In addition, in the instant food for storage that can be eaten by simply pouring drinking water or hot water into a canned food that can be eaten or hot water cooked food, and having a heat insulation structure in the can body,
It is an instant food for storage in which a water-cooked food or hot-water cooked food that is the contents is enclosed in a full open type sealed insulated double can,
A fully open canopy with a score formed on the lid surface and a pull tab attached thereto, a bottomed inner container integrally formed with a heat-resistant resin material in a cup shape,
It has a bottomed outer container consisting of a welded can that is formed in a cylindrical shape by double winding a can body member and a can bottom member,
While maintaining a space between the walls of the bottomed inner and outer containers to form a heat insulating space, the bottomed inner and outer containers and each flange portion of the canopy are closely polymerized, and triple-tightened,
The opening diameter at the time of opening is larger than the inner diameter of the mouth portion of the bottomed inner container, and the score of the full open canopy is formed so as to be smaller than the inner diameter of the mouth portion of the bottomed outer container,
It is characterized in that it is subjected to gas treatment by nitrogen gas replacement, or an oxygen scavenger is put in a bag and hermetically packaged.

  According to the present invention, because it constitutes a sealed insulated double can with a welded can as an outer container, it can contain instant food (same as hydrated cooked food or hot water cooked food) as its contents, and its long-term storage (sealability) ) And shape retention (including impact resistance based on high rigidity and transportability by loading packaging) can be improved.

  In particular, it can be expected to be used as stockpile foods for disasters and relief supplies for disaster and food shortages.

  The best mode for carrying out the present invention is a full-open type hermetically sealed double insulated can for instant foods having the above-described configuration, wherein a stacking groove is provided on the inner surface of the can bottom member so as to project along the inner periphery of the stacking groove. The bottom of the bottomed inner container is placed in the circumferential groove surface.
