Description of the Related Art Conventionally, as a heat-insulating paper cup container for pouring hot water into contents such as instant noodles to eat, corrugated paper is attached to the outside of the peripheral wall of the paper cup body that is water resistant, There are known thin papers that are laminated to form an air insulation layer, or water-resistant paper cups themselves are corrugated and thin paper is attached to the outer periphery to form an air insulation layer. . In addition, a heat-insulating paper cup container including a paper cup and an outer cylinder that covers the outer circumference of the paper cup, and an invention or device for forming an air heat insulating layer by providing a ridge protruding outward on a peripheral wall of the paper cup is disclosed in 4-2
There are inventions and inventions disclosed in No. 01840, No. Shokai 50-66978, No. Hei 6-44776, etc., and further, inventions and inventions in which a ridge protruding inward is provided on the peripheral wall of the paper cup. For example, there is a device disclosed in Japanese Utility Model Publication No. 52-97282.

When holding this cup container continuously for a long time, there was a problem that the fingers etc. became hot. There was also a problem that it was relatively weak in strength. Further, JP-A-4-201840,
The inventions and inventions disclosed in Japanese Utility Model Publication No. 50-66978, Japanese Utility Model Publication No. 6-44776, etc. are blocking when stacking a plurality of paper cup containers because the entire container surface linearly contacts the lower container. Sometimes it caused a phenomenon. Although the invention disclosed in Japanese Utility Model Publication No. 52-97282 is intended to eliminate the blocking phenomenon, the heat insulating layer is provided continuously in the lateral direction, and the strength remains unsatisfactory. there were.

断熱性紙カップ容器を提供するものである。In order to achieve the above object in the present invention, first, in the first invention, a paper cup container composed of a body portion and a bottom portion, and the body portion is covered with and adhered to the paper cup container. Characterized in that a spherical projection smaller than the finger width is provided on the entire surface of the body portion outwardly, and the heat insulating layer is formed by the spherical projection and the paperboard. An insulating paper cup container is provided.

て凸条が形成されていないので強度的にも強い。As described above, according to the present invention, the torso portion is provided with the spherical projection outwardly smaller than the finger width on the whole surface, and the outer surface side of the torso portion is attached with the paperboard to insulate it. Since the layers are formed, the contact between the paper cup container and the paperboard becomes punctiform, and when the paper cup container is gripped with fingers or the like, the contact area with the heat insulating layer is minimized and the heat is not felt. Since the spherical protrusions are provided on the entire surface, air can pass through the heat insulating layer in the vertical direction of the container, the paperboard itself is also air-cooled from the inside, and heat does not stay in the heat insulating layer, and It is not hot because the surface area becomes large and the air-cooling action works to reduce the heat at the contact area with the paperboard as compared with the inside of the cup. Since no ridge is formed over the entire circumference of the body, it is also strong in strength.

Since they do not come into contact with each other, friction at that portion is reduced, and blocking is less likely to occur.

材料費が安価で済む。As described above, according to the present invention, the spherical projection is directly provided on the body of the paper cup, and the paperboard is provided on the outer peripheral surface of the body to form the heat insulating layer. It became a heat insulating paper cup container with excellent heat insulating effect. Further, since the spherical protrusions are provided on the entire surface, the force against the external force from the lateral direction becomes strong, and the spherical protrusions are hard to be crushed even if the container is gripped with fingers and the like.
Furthermore, at least the uppermost part of the body is provided with a spherical protrusion projecting inward, so that blocking is unlikely to occur even when stacking the paper cup container, so that the suitability for filling and packaging of instant noodles, for example, is improved. . Since the paper cup itself has spherical protrusions, it is not necessary to use a special embossed paper,
Material costs are low.
