  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  As shown in FIGS. 1 and 2, the heat insulating container 1 includes a cup-shaped container main body 11 and an outer sleeve 21 that covers the upper outer peripheral surface of the side portion 12 of the container main body 11. Has a double structure. Thereby, heat is not transmitted to the outer surface of the container in the portion, and the heat insulating container 1 can be safely held. The container body 11 and the outer sleeve 21 are made of paper, but are not limited to this. For example, plastic may be used as a material.

  As shown in FIG. 3, the container main body 11 has an inverted frustoconical shape with an open upper end, and includes a cylindrical side portion 12 and a circular bottom portion 13 that closes the lower end of the side portion 12. On the upper edge of the side portion 12, an outward curling portion 14 that is rounded outward in the radial direction is provided. The side part 12 is formed by bonding the both end parts of the fan-shaped blank shown in FIG. In addition, a pair of vertical ruled lines 16, 16 are provided on the outer surface of the side portion 12 so as to face each other on a line where a vertical plane passing through the central axis of the container body 11 intersects. Horizontal ruled lines 17, 17 extending in the circumferential direction of the container body 11 from the lower ends of the vertical ruled lines 16, 16 are provided. Furthermore, a total of four diagonal ruled lines 18a, 18a, 18b from the lower ends of the vertical ruled lines 16, 16 that are the intersections of the horizontal ruled lines 17, 17 and the vertical ruled lines 16, 16, respectively, are obliquely downward on both sides. , 18b are provided. Since the oblique ruled lines 18a, 18a, 18b, 18b are at an angle (angle α) of approximately 30 degrees with respect to the horizontal ruled line 17 and its extension line 19, two oblique ruled lines 18a, 18b is approximately 120 degrees (angle β). In addition, although the horizontal ruled line 17 of this embodiment is extended only in one direction from the lower end of the vertical ruled line 16, as shown in FIG. 10, so that the lower part of the container main body 11 can be folded from any direction, It is preferable to form the horizontal ruled line 17 so as to extend from the lower end of the vertical ruled line 16 to both sides.

  As shown in FIG. 5, the outer sleeve 21 has a cylindrical shape, and an inwardly curled portion 22 (see FIG. 6) that is rounded inward in the radial direction is provided on the lower edge thereof. The height of the outer sleeve 21 is about half of the height of the side portion 12 of the container body 11. As shown in FIG. 9, after folding the lower portion of the container body 11, the lower end of the outer sleeve 21 is provided at a position where the end of the bottom 13 can be inserted between the outer surface of the container body 11 and the outer sleeve 21. It is preferable. However, the present invention is not limited to this, and in a state in which the outer sleeve 21 is attached to the container main body 11, the lower edge of the outer sleeve 21 extends from the center in the height direction of the container main body 11 to a circumferential adhesive region P described later (see FIG. 2). ) Is not limited in height dimension.

  In order to assemble the paper cup 1, first, the both ends of the blank-shaped trunk | drum 12 are piled up and adhere | attached, and it is set as a cylinder shape. And after attaching the bottom part 13 which bent the outer periphery to the lower end of the trunk | drum 12, the outward curl part 14 is formed in an upper edge, and the container main body 11 is created. Similarly, both end portions of the blank-shaped outer sleeve 21 are overlapped and bonded to form an inwardly curled portion 22 at the lower end portion as a cylindrical shape. Thereafter, a circumferential adhesive region P is provided on the lower outer peripheral surface of the outwardly curled portion 14 of the container body 11 by applying an adhesive in a circumferential direction with a width of about 20 mm, and the outer sleeve 21 formed in a cylindrical shape. The heat insulating container 1 is formed by inserting the container main body 11 into the container.

  When the container main body 11 is inserted into the outer sleeve 21, the container main body 11 and the outer sleeve 21 come closer to each other toward the upper part and come into contact with each other at the uppermost end. The part where the space | interval near this upper end becomes narrow is adhere | attached with the circumferential direction adhesion | attachment area | region P. FIG. The inwardly curled portion 22 of the outer sleeve 21 contacts the vicinity of the center in the height direction of the side portion 12, and an annular gap is formed between the inwardly curled portion 22 and the circumferential adhesive region P. This void plays a role of heat insulation.

  When the heat insulating container 1 is used and discarded, the lower portion of the container body 11 has a single structure and is exposed. Thereby, it becomes easy to press the side part 12 and to fold. Accordingly, when the heat insulating container 1 is used and discarded, the side portion 12 can be folded to reduce the volume and improve the discardability.

  Specifically, when the heat insulating container 1 is used and discarded, the vicinity of the exposed portion of the container main body 11 is grasped with both hands as shown in FIG. 7, and the heat insulating container 1 is crushed along the vertical ruled line 16 to be flat. And crushing along the diagonal ruled line 18a. Thereafter, as shown in FIG. 8, the bottom portion 13 is folded upward along the horizontal ruled line 17, and the heat insulating container 1 is further folded along the oblique ruled line 18 b. And as shown in FIG. 9, the upper end of the folding | returning part is inserted inside the exterior sleeve 21, and the deformation | transformation state made flat is maintained. At this time, since the bottom edge of the outer sleeve 21 is provided at a position where the bottom 13 of the container body 11 can be inserted between the outer surface of the container body 11 and the outer sleeve 21, the state in which the container body 11 is folded is reliably maintained. it can. As described above, by providing the ruled lines 16, 17, 18a, 18b, the container body 11 can be easily folded along the ruled lines 16, 17, 18a, 18b. For this reason, the volume of the heat insulation container 1 can be made small and discardability can be improved.
