（例えば特開昭６３−１３２０１７号）。2. Description of the Related Art Conventionally, as a heat insulating container for food, a container made of a material having a high heat insulating property such as foamed resin or corrugated board, or a double container having a heat insulating layer formed between the inner and outer containers, etc. Has been proposed and put into practical use. In addition, as a method of manufacturing a container, a technique has been proposed in which a molten resin flow path is formed in a cavity mold and a resin is allowed to flow through the flow path to manufacture a container having a thinnest possible wall thickness. (For example, JP-A-63-132017).

まれていた。Further, a container in which a ridge is formed on the outer side of the container has been proposed, but the conventional ridge is for the purpose of reinforcement, and its height can be set within a range for achieving the reinforcement purpose. It was required to be as low as possible. Also in the above-mentioned manufacturing method, the flow path of the molten resin formed in the cavity mold should be as inconspicuous as possible in the molded container, that is, the depth of the flow path should be as shallow as possible. Was wanted.

い。Further, it is a general technique to provide a radiating strip (radiating fin) on the outside of the container, but the purpose of providing the radiating fin to the conventional container is to cool the container itself or the inside of the container. However, it is not known to provide a radiating fin for the purpose of heat insulation that the container is not hot when held.

ない容器が要求されている。Among the conventional heat-insulating food containers, those using foamed resin are weak against heat and are not suitable for heating in a microwave oven, and those using corrugated cardboard and double containers are not suitable. There was a problem that the manufacturing cost was high. Therefore, a food container that is resistant to heat, has a high heat insulating effect, and has a low manufacturing cost is desired. In particular, as a container for frozen foods, a container that has sufficient strength when distributed as frozen foods, has sufficient heat resistance when heated in a microwave oven, and is not hot to hold in the hand when heated is required. Has been done.

Therefore, even if the contents of the container become hot, the leading edge of the ridge will not become hot. The height of the ridges and the distance between the adjacent ridges are set so that the fingers do not touch the peripheral wall of the container when held by hand, so it is not hot for the hand to touch when holding the container. Only the edge of. Therefore, even if the contents are hot and the peripheral wall of the container is too hot to hold by hand, the hand only touches the tip edge of the ridge, so that the container can be held without feeling any particular thickness.

周壁２に触れないようにしてある。First Embodiment In FIG. 1, a large number of vertical ridges 3 are formed at equal intervals on the outside of a peripheral wall 2 of a cup-shaped container 1 made of synthetic resin (olefin resin such as polypropylene and polyethylene). The heat-insulating food container of the present invention.
The ridge 3 has a V-shaped cross section, a height of about 1.5 mm, a base width of about 1 mm, and an interval between adjacent ridges of about 5 mm (center-to-center) to grab the container 1 by hand. At that time, the fingers do not touch the peripheral wall 2.

ができる。In this container 1, the ridges 3 have a heat radiation effect, so that even if hot water or the like is stored in the container 1 and the peripheral wall 2 becomes hot, heat is radiated by the ridges 3 so that the tip edge of the ridges 3 is heated. Three
The temperature of a remains relatively low, and even if it is touched by a finger, no particular heat is felt. The size and arrangement of the ridges 3 are such that the fingers do not touch the peripheral wall 2, so that when the container 1 is grasped, the fingers do not touch the peripheral wall 2 of the container having a high temperature, and the ridges having a low temperature are provided. Because you only touch 3.
Even if the contents are hot, you can hold the container without feeling the heat.

有するものであればよい。In this embodiment, the material of the container is olefin-based. Since this material is strong in both cooling and heating, it is suitable as a container for frozen foods that is stored in a freezer and heated in a microwave oven under severe conditions. And, as mentioned above, it is not hot when held by hand when heated and eaten. Therefore, it is suitable as a container for frozen food that can be eaten while being heated and placed in the container. When used as a container for frozen food that is cooked by heating and eats as a container, the material may be any one having heat resistance of about 100 ° C. or higher in addition to the above-mentioned olefin resin.

ミリ程度が限界であろう。The size and spacing of the protrusions 3 are not limited to those in the above embodiment. The point is that the fingers do not have to touch the peripheral wall 2 of the container 1 when the container is held by hand.
Therefore, if the height of the ridges is increased, the distance between the ridges can be increased, and if the height of the ridges is decreased, the distance between the ridges must be reduced. However, if the height of the ridge is extremely low, the heat dissipation effect cannot be expected, so the height of the ridge is 1
The limit is about millimeter.

That is, the injection port 13 is formed in the center of the bottom portion 12 corresponding to the bottom of the container 1, and the bottom resin flow passage 14 radially branched from the injection port 13 is formed as a shallow groove (depth mm). I am doing it. This bottom surface resin flow path 14 is branched over several orders, and the bottom portion 1
At the periphery of 2, the number of branches is equal to the number of ridges 3 to be molded. A peripheral wall resin passage 16 corresponding to the ridge 3 is formed in a peripheral wall portion 15 corresponding to the peripheral wall of the container 1 of the cavity mold 11 with a deep groove having a V-shaped cross section.

業製よく製造することができる。The cavity mold 11 and the core mold 17 are set in combination, and the molten resin is injected at a high pressure from the injection port 13 of the cavity mold. The injected resin flows through the bottom surface resin flow path 14 and reaches the weir 18. At this time, the resin dammed up by the weir 18 flows out from the bottom surface resin flow passage 14 to form the bottom surface of the container, and at the same time, passes over the weir 18 and the peripheral wall resin flow passage 1 is formed.
6, the ridge 3 is formed, and the resin flowing out from the ridge 3 forms the peripheral wall 2. Since the resin flows at a high pressure, the container 1 is instantaneously molded. As described above, according to the method of the present invention, it is possible to manufacture the heat-insulating food container having the ridge with good workability.
