Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heat-insulating container for instant food used for packaging instant noodles and the like.

[0002]

[Prior art]

 There are two types of heat-insulating containers for instant foods used for packaging instant noodles, such as those made of foamed synthetic resin and those made of water-resistant paper. The former does not require a special structure for heat insulation because it has an insulating effect. The latter does not have its own insulation function and thus requires a special construction for insulation. As a special structure for this heat insulation, it is known that a corrugated plate-like surface insulation plate cover is attached to the outside of the peripheral wall of a water-resistant paper-made container body. It is also known that the corrugated plate is used and the surface cover is made flat.

[0003]

[Problems to be solved by the device]

 The publicly known water-resistant paper-made heat insulating container uses a corrugated plate for either the container body or the surface heat insulating plate cover, and forms an air heat insulating layer between the container body and the surface heat insulating plate cover. There is. However, in the known container, since the container body and the upper and lower end positions of the surface insulating plate cover were in close contact with each other, the air in the air insulating layer was also heated, and a sufficient heat insulating effect was not obtained, and the container was gripped. There was a problem that I felt hot sometimes.

Further, in the conventionally known heat insulating container, since the inclination angle of the inner wall of the container body and the inclination angle of the surface insulating plate cover are the same, when stacking a plurality of containers, the entire outside of the surface insulating plate cover is covered. There was also a problem that the lower container closely contacts the inner surface of the container body and causes blocking.

The present invention is an instant food heat insulating container in which a surface heat insulating plate cover is attached to the outside of a peripheral wall of a water-resistant paper container body, and has a higher heat insulating effect than the conventionally known container. It is also an object of the present invention to provide a new heat-insulating container having the above, and further to provide a new heat-insulating container that does not cause blocking even if a large number of containers are stacked.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the instant food heat insulating container of the present invention is a surface heat insulating plate formed by press-working a large number of inward projections on the outer surface of the peripheral wall of a water-resistant paper container body. A cover is attached to form a gap that communicates between the container body and the surface heat insulating plate cover, and a gap is provided between the upper and lower edges of the surface heat insulating plate cover and the container body without close contact. It is constructed so that air can flow between the container body and the surface insulating plate cover.

[0007]

[Action]

 In the instant food heat insulation container of the present invention, the surface insulation plate cover, which is formed by pressing a number of inward projections, is attached to the outer surface of the peripheral wall of the container body. Since a heat insulating layer is formed and there is a gap between the container main body and the heat insulating plate cover at the upper and lower edges of the container without airtightness, there is always air flow between the container main body and the heat insulating plate cover, and the container is heated. The air is sent out.

Further, in the heat-insulating container for instant food of the present invention, the height of the upper edge of the surface insulating plate cover from the container body and the height of the lower edge from the container body are the same. Since the surface insulation plate cover is inclined with respect to the surface of the container body so that it is higher than the height of the container, when stacking multiple containers, only the lower end of the surface insulation plate cover comes into contact with the inner surface of the lower container, Except for the lower end, the entire surface of the heat insulating plate cover does not contact the inner surface of the lower container.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 to 3 show a preferred embodiment, and FIGS. 4 to 6 show another embodiment. In the figure, reference numeral 1 is a water-resistant paper container body, which is no different from the conventionally known paper container of the heat-insulating container for instant food. In the figure, reference numeral 2 denotes a surface heat insulating plate cover, which is made of paper like the container body. The surface heat insulating plate cover 2 is attached to the outer surface of the peripheral wall of the container body 1 with the upper edge 3 thereof slightly below the upper end protruding portion 4 of the container body 1 with a gap 5 therebetween.

The surface heat insulating plate cover 2 is formed by pressing a large number of convex portions 6 inward, and the tip portions of the convex portions 6 are attached to the container body 1 to form a container. A gap 10 communicating with the main body 1 and the surface heat insulating plate cover 2 is formed. A particularly characteristic feature of the present invention is that the upper and lower edges 3 and 7 of the surface heat insulating plate cover 2 and the container body 1 are provided with gaps 8 and 9 without being in close contact with each other. The gaps 8 and 9 provide good air circulation between the container body 1 and the surface heat insulating plate cover 2.

Further, in the heat insulating container of the present invention, the height of the upper end edge 3 of the surface insulating plate cover 2 from the container body 1 and the height of the lower end edge 7 from the container body 1 are the same as the height of the lower end edge 7. The surface heat insulating plate cover 2 is inclined with respect to the surface of the container body 1 so as to be higher than the height of the upper edge 3 (shown in FIG. 3).

In the embodiment shown in FIGS. 1 to 3, the convex portion 6 is formed in a circular shape, but FIGS. 4 to 6 show that the convex portion 6 is formed in a diamond shape. There is no difference between these examples except that the shape of the convex portion is different. Therefore, in FIGS. 4 to 6, the same reference numerals as those in FIGS. 1 to 3 are attached. Therefore, the shape of the convex portion 6 may be another shape. Further, in the illustrated embodiment, the convex portion 6 is formed only toward the inside of the surface heat insulating plate cover 2, but a large number of uneven portions may be formed on the front heat insulating plate cover. Good. The point is that a gap 10 that communicates between the container body 1 and the surface insulating plate cover 2 may be formed.

[0013]

[Effect of device]

 In the heat-insulating container of the present invention, since the surface heat insulating plate cover having a large number of inwardly projecting projections is attached to the outer peripheral surface of the container body, the adhesive portion is the tip of the projecting section, The heat conduction to the surface heat insulating plate cover is low, and a gap is formed between the container body and the surface heat insulating plate cover, and the container body and the surface heat insulating plate cover are in close contact at the upper and lower edges. Since there is no gap, air is constantly circulated between the container body and the surface heat insulating plate cover, heat is efficiently released, and a particularly good heat insulating effect is obtained.

Further, in the container of the present invention, when the surface insulating plate cover is inclined with respect to the container body and a plurality of containers are stacked, the entire container surface does not adhere to the lower container, and only the lower end of the container is attached. Since they are brought into contact with each other, there is an advantage that blocking does not occur.
