【Example】

  FIG. 1 is a cross-sectional view of a heat insulating container A according to an embodiment of the present invention. 2 is tightly fitted. The container body 1 is mainly composed of talc and polypropylene. A non-foamed resin sheet molded product (for example, about 90 mm in both diameter and height) An annular convex portion 3 is formed on 1/3. The annular convex portion 3 has a large diameter toward the mouth portion. It has a tapered shape, and the inclination angle of the outer wall is the extension of the tapered surface and the lower end of the container body. 4 is positioned.   Six ribs 5 (for example, a height of about 3 mm) are continuously arranged at equal intervals on the lower end of the annular convex portion 3. The upper surface of the rib 5 has a tapered shape with the same inclination as that of the annular convex portion 3. It In the drawing, the length of the rib 5 is about 1/4 of the annular convex portion 3, but The length may reach the lower portion of the container body 1.   The lower end portion 4 of the container body 1 is formed with a slight taper whose diameter increases toward the lower end. The lower end 7 of the tubular body 2 is locked. In addition, at the lower end of the container body 1 The material is bent upward to form a raised bottom 6, and the taper The inside of the container-shaped lower end portion 4 is a cavity.

[0007]   On the other hand, the cylindrical body 2 is made of cardboard and has a tapered shape with an opening at the top and bottom. It The inclination angle of the side surface is the same as the inclination angle of the annular convex portion 3 of the container body 1. The upper part of the tubular body 2 is tightly fitted to the annular convex portion 3. In addition, the lower end 7 of the cylindrical body 2 is It is located slightly above the lower end of the container body 1, and the lower end of the tubular body 2 is tapered. The container is locked to the lower end 4 of the container body, and together with the close fitting with the annular convex portion 3 in the upper part, The body 2 is not easily separated from the container body. The lower end diameter of the cylinder 2 is It is slightly smaller than the lower end diameter of the container body.   Since the cylindrical body 2 has a tapered shape having the same inclination angle in the vertical direction, From the lower end of the annular convex portion 3 of the main body 1 to the contact portion between the container main body 1 and the cylindrical body 2 at the lower end portion Between the upper and lower central portions of the cylindrical body 2 to the lower portion, the outside of the container body 1 and the cylindrical body A gap 8 is formed between the body 2 and the inside.

[0008]   In order to obtain the heat-insulating container A shown in this embodiment, the preformed container body 1 has its lower end The tubular body 2 is fitted from the side. Then, the upper part of the cylindrical body 2 is closely attached to the annular convex portion 3 of the container body 1. By fitting and fitting the lower end 7 into contact with the lower end 4 of the container body, No. 2 is fixed to the container body 1 and there is no risk of it coming off during normal use.

[0009]   The heat-insulating container A of the above-mentioned embodiment is usually heated below the lower edge of the annular protrusion 3 of the container body 1. (Most are hot water). If you pour hot water into the container body 1, Although it is conducted to the cylinder 2 through the container body 1, a gap 8 is formed between the container body 1 and the cylinder 2. Since it exists, the heat conduction is blocked by the gap 8 and the amount of heat conducted to the cylinder 2 is small. Moreover, the cylindrical body 2 itself is made of paper and has a relatively low thermal conductivity. Therefore, FIG. As you can see, the heat you feel when holding the heat-insulated container A from the center of the top to the bottom with your hand is This is remarkably reduced as compared with the case of the main body 1 alone.   Further, according to the above embodiment, since the bottom 6 of the container body is raised, the heat insulating container A When you put your hand on the bottom edge of the hand, the hand does not touch the bottom 6 and you cannot feel the heat. Absent.

[0010]   Since the ribs 5 are provided in the above embodiment, the ribs 5 serve as a support for the cylindrical body 2 and the gap 8 It is possible to prevent narrowing, and it has a good sense of stability when held by hand, and Reinforces the container body. In addition, when holding this heat-insulating container A, a thumb and a person Since the circumference of the container is surrounded by about 2/3 with the index finger and middle finger, the thumb and index finger or middle finger Correspondingly, it is effective to provide six ribs 5, but the number is arbitrary. Well If a rigid paper such as corrugated cardboard is used, the gap 8 can be maintained without ribs. Therefore, it is not essential to provide the rib.

[0011]   In the above embodiment, the lower end 7 of the cylinder body 2 is locked to the lower end portion 4 of the container body 1. As a result, it is possible to fix both by simply fitting the tubular body 2 into the container body 1. , Easy to manufacture and when separating the container body made of resin and the cylindrical body made of paper Also, it can be separated relatively easily.   The locking structure of the cylindrical body 2 at the lower end of the container body 1 is the same as in the above embodiment. In addition to the tapered structure, an annular convex shape may be formed on the lower end of the container body 1.

[0012]   The fixing structure of the container body 1 and the cylindrical body 2 is not only by locking but also by fixing both with an adhesive. Good. Also, if a foaming resin is applied to the inside of the cylinder 2 in a non-foaming state, pouring The foaming resin is foamed by the heat of the time, and the cylindrical body 2 and the container body 1 are fixed to each other. Moreover, departure Since the foaming resin has a heat insulating effect, a further heat insulating effect can be obtained.   Further, the materials of the container body 1 and the cylindrical body 2 are not limited to those of the above embodiment. Absent. In the above examples, resins made from talc and polypropylene were used. It can be burnt as dust, but other resins may be used. Yes. Even in that case, unlike the conventional foamed resin container, it can be easily crushed, so dust It can contribute to the reduction of the amount.   Further, if the tubular body 2 is made of corrugated cardboard, the heat insulating effect can be further improved.

[0013]

[Effect of device]

  According to this invention, the cylinder body is fitted into the container body molded of non-foamed resin, Since a gap is provided between the cylinder and the cylinder, the heat conduction of the contents of the container body depends on the gap. Be blocked. Therefore, the container main body made of non-foamed resin and the paper cylinder A sufficient heat insulating effect can be obtained by coupling   In addition, the cylindrical body has a tapered shape, and the upper portion thereof has a tapered shape formed on the container body. Formed in the middle part because the lower end was abutted against the lower end of the container body The gap to be held is reliably maintained.   And since the container body is a non-foamed resin, it can be easily crushed and When treating a container as garbage, it is practical The capacity can be significantly reduced.
