The body of the heat-insulating paper cup container of the present invention comprises a paper cup and an exterior sheet, and the basic constitution of the lamination is (inner) polyethylene / cup base paper having an opening / paper material (outer)
Configuration, (inner) polyethylene / cup base paper with perforations / paper material / polyethylene / paper material (outer) configuration etc. As the exterior sheet attached to the body of the paper cup container, paper materials such as coated balls can be preferably used,
If the grammage is 180 g / m 2 or less, the rigidity will be reduced and the paper will be deformed when held by hand, and the paper thickness will be thin, resulting in poor heat insulation effects. It will be difficult. Further, when the basis weight is 270 g / m 2 or more, the rigidity becomes too strong, the work of winding around the paper cup becomes difficult, and the problem of peeling after adhesion to the paper cup occurs. For these reasons, the basis weight of the paper material used for the exterior sheet is preferably about 180 to 270 g / m 2 . Further, when the exterior sheet is a laminated sheet, it is not limited to the three-layer structure and may have a two-layer structure or a four-layer structure or more. Further, the material forming the laminated sheet also has a heat insulating effect. The material is not limited to polyethylene as long as the material improves the property.

材料を作製した。Example 1 FIG. 1 is a side view of the heat-insulating paper cup container of the present example, in which a part is cut away, and a laminated material for forming a side wall of the heat-insulating paper cup container. It is sectional drawing (b) which expanded the A section. First, basis weight 210g /
1 small hole having a diameter of 5 to 15 mm is formed on a roll-shaped or sheet-shaped cup base paper (13) having a size degree of 1000 seconds at m 2.
Open holes at a rate of 5 to 40 pieces / m 2 . In this case, if the diameter of the small holes is 5 mm or less, a sufficient heat insulating space cannot be obtained and the heat insulating effect is inferior, and if the diameter of the small holes is 15 mm or more, the exterior sheet has this size when held by hand. There is a problem that it falls into the small hole (14) and a sufficient heat insulating space cannot be obtained, resulting in a poor heat insulating effect. On one side of the cup base paper (13) provided with the apertures (14), polyethylene (1 μm) of 20 μm was formed by the extrusion lamination method.
2) was laminated to produce a laminated sheet forming a paper cup body. Separately, a laminated material having a (inner) polyethylene / cup base paper (outer) constitution for forming the bottom portion (21) was prepared.

Adhesives such as hot melt adhesives (1
The heat insulating paper cup container of the present invention was completed by forming a heat insulating layer by winding through 5). At this time, it is necessary to take care so that the adhesive (15) is not applied to the opening (14). This is because when the adhesive (15) gets into the opening (14), the volume of the heat insulating space due to the opening (14) decreases and the heat of the polyethylene on the inner surface passes through the adhesive. This is because the heat insulating effect is poor due to conduction to the paper board (16) which is a material. The paperboard (16) may also be provided with a printing layer (20).

And 9) are laminated by a extrusion lamination method using molten polyethylene (18) to form a laminated sheet having a three-layer structure. This exterior sheet is punched out into a size substantially the same as the body of the paper cup container, and an adhesive (15) such as a hot melt adhesive is applied to the body (11) of the paper cup container (10) as in Example 1. The heat-insulating paper cup container of the present invention was completed by winding through and forming a heat-insulating layer.

品価値が向上する。As described above, according to the present invention, since the paper cup container is formed by using the cup base paper having the opening, and the exterior sheet is attached to the outside of the body, the paper cup container A heat insulating layer having an air layer is formed on the body,
Since the conduction of heat from the inside to the outside is suppressed, the outside of the body can be held by hand. As for the treatment after use, the disposal is easy because the paper material is mainly used. It can be incinerated without any problems. In addition, it can be manufactured using a normal paper cup molding machine, and the paper material or the exterior sheet after the paper cup molding can also be pasted with a simple wrapping machine, compared to the method of pasting corrugated material. It is economical because the number of manufacturing processes does not increase. Furthermore, since the outermost layer is made of paper, offset printing and gravure printing can be performed on the surface of the container to make the color beautiful, and the store display effect during distribution is good and the product value is improved.
