器の提供を目的とする。However, the above-mentioned heat insulating material obtained by winding a corrugated insulating material around the body of the cup body is actually hand-operated irrespective of the cross-sectional shape of the heat insulating material. There is a problem that the upper part of the heat-insulated container that is not touched is finished unnecessarily thick. In addition, there is a problem that letters, designs, and the like printed on the surface are very difficult to see due to the unevenness of the surface, and it is difficult to give a luxurious design. In order to solve this appearance problem, the actual opening 49-8
No. 7479, Japanese Utility Model Publication No. 4-45216, and the like propose a heat insulating container having a liner or a thin paper to further form an uneven shape even if such an external appearance problem is solved, but the yarn end of the heat insulating container is not uniform. In addition, when viewed from below, there is still a problem with the appearance that uneven sections or embossed cross-sections can be seen from the bottom of the thread, and furthermore, sanitary conditions in which trash enters and liquids penetrate through these gaps Problem. Another problem is that the manufacturing cost is excessively increased. FIG. 5 is a cross-sectional view of a conventional heat-insulating container.
No. 2 has been proposed. As shown in FIG. 5, the heat insulating container 40 includes a curl portion 16 curling inward at a lower end with respect to a body side wall 11 of a paper cup body having a bottom plate 12 and a top curl portion 13 curling outward.
A cylindrical body 15 having a cylindrical shape is inserted into the cylindrical body 15, and the two are vertically fixed to each other to be fixed and integrated, and a heat insulating space is formed by utilizing the thickness of the curled portion 16 of the cylindrical body 15. ing. Since the heat insulating container 40 does not particularly use the heat insulating material having the uneven shape, the above-mentioned disadvantages caused by the heat insulating material have been solved. The shape body 15 is likely to bend (warp) in an inward direction, and as a result, there is a problem that a space interval is lost and heat insulation is insufficient. The present invention has been made in view of the above-described problems, and has an object to provide a paper heat insulating container having stable heat insulating properties, excellent designability, high degree of freedom in printing expression, and low manufacturing cost.

できる。The outwardly projecting horizontal ribs 4 provided on the body side wall 1 of the cup body 10 function to reinforce the strength of the cup body 10 and form a heat insulating space.
One or more may be used. In addition, the position may be appropriately determined in consideration of the strength balance of the cup body 10, and one of the positions is, as shown in FIG. 1 (c), appropriate for hot water supply when pouring hot water into the cup body. The level indication line, that is, the hot water entry line 7 may also be used. The heat insulating container 30 according to the present invention shown in FIG. 1C differs from the conventional heat insulating container 40 shown in FIG.
Since the fulcrum of the side wall 5 is zero, the inward bending of the side wall 5 of the tubular body 20 can be reduced when the body is held by hand, so that the interval between the heat insulating spaces is maintained. As a result, good heat insulating properties can be obtained. By controlling the height of the horizontal ribs 4 and the degree of protrusion of the inward curl portion 6 of the tubular body 20, the interval between the heat insulating spaces of the heat insulating container 30 according to the present invention becomes substantially uniform or increases toward the lower end. Predetermined intervals can be provided, and heat insulation can be imparted to all side walls, which was impossible with the conventional heat insulating container 40. Thus, according to the present invention, the soup,
Needless to say, when the level of hot water supply such as miso soup is relatively low, even when hot water is supplied to the upper part of the heat insulating container like a cup ramen, a heat insulating container that can withstand use can be supplied.

The horizontal ribs 4 may be continuously circulated around the body side wall 1 as shown in FIG. 2A, or intermittently circulated as shown in FIG. 2B. May be.
When the number of the horizontal ribs 4 is the same, the intermittent rotation is slightly inferior in preventing the side wall 5 of the tubular body 20 from bending, but the heat insulating space is expanded, and the heat insulating space communicates up and down. Since the movement of the heated air in the entire space is easily performed, the temperature rise is homogenized, and as a result, the effect of improving the heat insulating property is obtained. When the notch 8 is provided by intermittently connecting the horizontal ribs 4 as described above, the number of divisions is 4 to 8 with respect to the entire circumference, and the ratio of the notch 8 to the entire circumference is 30%. The following is preferred.

い。FIG. 3 is a sectional view of a horizontal rib of the heat insulating container according to the present invention. The shape of the horizontal ribs 4 formed on the cup body 10 is preferably a sharp protrusion as shown in FIG. 3A in order to widen the heat insulating space. It is premised that the processing suitability of the paperboard used for the cup body 10 is excellent. On the other hand, the horizontal rib 4 having a gentle inclination as shown in FIG. 3 (b) can be easily formed regardless of the paperboard quality, but the joint area of the side walls 1, 5 increases, In addition, since the heat insulating space is reduced, heat insulation is lost, which is not preferable. Therefore, the horizontal rib 4 having a cross section as shown in FIG.
Is most preferable from the viewpoint of heat insulation properties and workability (described later).

ためである。In FIGS. 1 and 3, all the horizontal ribs 4 are illustrated as contacting the cylindrical body 20.
At least one only needs to be in contact with the other horizontal rib 4
Need not be in contact. Rather, those who are not in contact with each other have a slight bending after hot water supply cooking, but have a low surface temperature and are easy to hold. This is because the horizontal ribs 4 that do not come into contact make the heat insulation space larger, and convection of air in the side walls 1 and 5 easily occurs up and down, and heat is easily dispersed.

As shown in FIG. 4A, a horizontal rib 9 protruding inward toward the cylindrical body 20 may be provided at a position facing the horizontal rib 4 of the cup body 10. Generally, in processing horizontal ribs, the height of the horizontal ribs is limited by the paper quality, so that extremely high horizontal ribs cannot be processed. So, horizontal rib 4,
By making the horizontal ribs 9 face each other, the same effect as that of a tall rib can be obtained, and the gap in the space can be increased. Further, as shown in FIG. 4B, an upper space may be formed by providing an inward curl portion 6 'also at the upper end of the tubular body 20.

とができる。The internal volume targeted by the heat insulating container 30 according to the present invention is 200 to 500 cc when fully filled. To mold the paper cup body 10 having an internal volume in this range in a conventional paper cup forming machine, the use of the basis weight of the cup base paper of 160g / m 2 ~300g / m 2 is preferred. Usually, a polyolefin-based resin layer such as a low-density polyethylene resin, a medium-density polyethylene resin, a high-density polyethylene resin, or a linear low-density polyethylene resin is extrusion-coated on the inner surface of the cup base paper in a range of 20 to 80 μm. . This polyolefin-based resin layer not only prevents the penetration of the contents into the paperboard and improves the suitability for protecting the contents, but also improves the moldability of the cup at the bottom, the curled portion, and the body sticking portion. This has the effect of improving the sealing properties of the top curl portion by heat sealing. In addition, when hot water comes into contact with the plastic layer on the inner surface of the container, sufficient consideration must be given to the fact that monomers remaining in the plastic, heavy metals used in the polymerization catalyst, and other additives are easily eluted. It is a problem of food contamination by them. In this case, it is natural that the amount of these eluted does not exceed the standard value defined by the Food Sanitation Law, but even a trace amount less than this value, for example, often used for baby bottles and tableware for school meals Dissolves environmental hormones (exogenous endocrine disrupting chemicals) that have been pointed out to disturb the endocrine secretion of living organisms, such as bisphenol A eluted from polycarbonate resins and styrene oligomers eluted from expanded polystyrene containers. The use of resin
It is desirable to avoid it from the precautionary principle. In the heat insulating container 30 according to the present invention, a non-added resin is further selected and used from the polyolefin-based resin having a small risk, so that it can be used on the innermost surface of the heat insulating container with a sense of security.

べれば、極めて環境負荷の小さなものである。The paperboard used for the tubular body 20 is required to have curability and formability simultaneously with printability, and has a basis weight of 230 g / m 2.
~ 350 g / m 2 coated cardboard or 160 g
/ M 2 to 250 g / m 2 card paper can be suitably used. If the grammage is less than this limit, the rigidity of the tubular body 20 becomes too low, and the deflection becomes too large, particularly at high heat, to lose sufficient heat insulating properties. However, it is not preferable because the processing suitability of the inward curl portion 6 is deteriorated and the material cost is increased. The material of the cylindrical body 20 is further subjected to a resin coating or a resin impregnating treatment to enhance the rigidity, compression resistance, crush resistance and the like of the entire heat insulating container 30 according to the present invention, and to reduce the content from the external force applied during distribution. It can function to protect things. In addition, as described above, not only the stable insulation properties of the entire heat insulation container but also the rigidity that makes it hard to deform is the safety and reliability of tableware when pouring hot water and eating it with your hands as it is This is an important factor especially for the elderly, the physically handicapped, and children, and an indispensable factor for barrier-free products. The insulated container according to the present invention is made of paper, does not need to be discarded after use, has a good disposal property, and even if it has rigidity, it can be easily crushed by crushing by hand. Things,
Volume reduction upon disposal is easy. Therefore, compared to other heat insulating containers using foamable plastic as the heat insulating material, they have a very small environmental load.
