十分でなく、断熱効果を高めるために二重構造にすると
コスト高になるという問題点があった。The container made of foamed resin is excellent in heat insulating property, but when printed directly on the outer surface of this container, the printing becomes unclear. Also,
In the case of containers made of foamed resin, many containers of the same size are stacked in an empty state, and one container is automatically taken out from this stacked container group and filled with food. There is also a disadvantageous problem that stacking (or blocking) occurs in which two containers are in close contact with each other and are difficult to separate from each other, and two containers may be picked up at one time. on the other hand,
Paper containers have a clear and visually appealing effect (visual effect) when printed on the outer surface, and while they are recyclable and easy to incinerate, they do not have a sufficient heat insulating effect and therefore have a heat insulating effect. There is a problem in that the cost increases if a double structure is used to increase the cost.

め、見映えの巻き付け状態に仕上げられる。If the flange is formed such that the outer peripheral edge thereof is bent downward, the flange has a rigid cross-sectional shape, and when the ramen juice or the like in the container is sucked, the flange is opened. There is an advantage in that it feels good without giving a feeling of scratching and can be used for winding the tab of the lid. However, when the body cover body is wrapped around the body of the container body having the flange of such a cross-sectional shape, in order to wind the body cover body so that the upper end edge of the body cover body contacts along the lower surface of the flange, the downward outer peripheral edge of the flange is used. As a result, the outer surface of the body cover body is exposed from between the lower surface of the flange and the upper edge of the body cover body, resulting in a poor-looking finish. Therefore, in order to finish the body cover body in a good wrapped state in appearance, after temporarily winding the body cover body around the outer surface of the body of the container body, the upper edge of the body cover body is placed on the lower surface of the flange. The body cover body is moved in the axial direction of the container main body on the outer surface of the body until it abuts, and the body body is bonded. According to this
Since the problem that the outer surface of the body cover body is exposed from between the lower surface of the flange and the upper end edge of the body cover body is eliminated, the appearance is wrapped in a finished state.

Both can be easily separated by peeling off,
The body cover made of paperboard can be incinerated or recycled, and the container body made of foamed resin can be recycled. In this case, if the total weight of the body cover that is made of paperboard and is easy to incinerate or recycle is larger than that of the container body made of foamed resin, the cost of incineration or recycling will be reduced. It will be possible.
