  Embodiments of the present invention will be described below with reference to the drawings. However, the embodiment shown below exemplifies the lunch box for embodying the technical idea of the present invention, and the present invention does not specify the lunch box as follows.

  Further, in this specification, in order to facilitate understanding of the scope of the utility model registration request, the numbers corresponding to the members shown in the examples are referred to as “the scope of the utility model registration request” and “the means for solving the problems”. It is added to the members shown in the column. However, the members shown in the claims of the utility model registration are by no means specified as the members of the embodiment.

  The lunch box shown in the perspective view of FIG. 1 and the cross-sectional view of FIG. 2 includes a paper box composed of a rectangular box body 1 and a lid 2, and a plastic inner container 3 detachably set inside the paper box. Is provided.

  The box body 1 and the lid 2 are made of paper, and the box body 1 and the lid 2 are provided with peripheral walls 5 and 6 around the box body 1 and the lid 2. The peripheral walls 5 and 6 are connected to the adjacent peripheral walls 5 and 6 with a margin, or are connected to the adjacent peripheral walls 5 and 6 through a decorative sheet 7 that adheres to the surface.

  The box body 1 is provided with an inclined peripheral wall 5 that is inclined in the direction of increasing the opening area toward the upper opening around the rectangular bottom plate 4. In the illustrated lunch box, the bottom plate 4 of the box body 1 is square, but the bottom plate 4 of the box body 1 is not limited to a quadrangle, and may be a polygon such as a rectangle or a pentagon.

  The box body 1 has an inclination angle of the inclined peripheral wall 5 with respect to the bottom plate 4 that is, for example, an obtuse angle that is 3 degrees to 10 degrees larger than a right angle. Further, the box body 1 is formed so that the bottom plate 4 is smaller by 5 mm to 15 mm, preferably about 10 mm, in a side view than the upper end of the inclined peripheral wall 5, that is, the opening area, due to the inclination of the inclined peripheral wall 5. In this way, the inclined peripheral wall 5 is inclined so that the cross-sectional area of the box main body 1 decreases in the downward direction, so that when the plurality of box main bodies 1 are stacked, the overlapping state is moderate along the inclination of the inclined peripheral wall 5. It is possible to make the structure easy to stack. In addition, the appearance of the appearance is improved by slightly inclining the inclined peripheral wall 5. The box body 1 is manufactured by bending a piece of cardboard at the boundary between the bottom plate 4 and the inclined peripheral wall 5. The lid 2 is provided with a peripheral wall 6 in a vertical posture that is not inclined around the top plate, but the lid 2 is also manufactured by bending a piece of cardboard at the boundary between the top plate and the peripheral wall 6.

  The box body 1 and the lid 2 have a decorative sheet 7 bonded to the outer surface. The decorative sheet 7 is paper having a surface that is colored or printed with a pattern, or a surface that is provided with an uneven pattern such as a satin finish. Preferably, a decorative sheet embossed on the heel pattern is used. As a result, it is possible to produce a Japanese-style taste by arranging an uneven pattern of candy like Japanese clothes on the surface. In particular, it is possible to add a sense of quality while using a cheap lunch box made of paper. In addition, by making the decorative sheet embossed with a coral pattern black or vermilion, it is possible to produce a more Japanese-style taste such as a festival. However, the decorative sheet 7 is not limited to paper, and a flexible sheet material such as cloth or nonwoven fabric can also be used. The box body 1 has a decorative sheet 7 bonded to the entire outer surface of the bottom plate 4 and the inclined peripheral wall 5. Further, the box body 1 has the inner surface adhesive portion 11 of the decorative sheet 7 bonded to a part of the inner surface of the inclined peripheral wall 5. The inner surface bonding portion 11 of the decorative sheet 7 bonded to the inner surface of the inclined peripheral wall 5 is bonded by folding the decorative sheet 7 bonded to the outer surface of the inclined peripheral wall 5 at the upper edge of the inclined peripheral wall 5.

  FIG. 3 shows a development view of the decorative sheet 7 bonded to the box body 1. The decorative sheet 7 includes a bottom adhesive portion 13 that adheres to the outer surface of the bottom plate 4, an outer surface adhesive portion 14 that adheres to the outer surface of the inclined peripheral wall 5, and an inner surface adhesive portion 11 that adheres to the inner surface of the inclined peripheral wall 5. . Since the bottom bonding portion 13 is bonded to the surface of the bottom plate 4, it is equal to the outer shape of the bottom plate 4, and the outer surface bonding portion 14 is equal to the outer shape of the inclined peripheral wall 5. The outer surface bonding portion 14 is provided with a slit 15 at both ends. FIG. 5 shows a development view of the box body 1 to which the decorative sheet 7 having the glue 15 is bonded. The box body 1 shown in this development view does not have a slit on both ends of the inclined peripheral wall 5. This is because the slanting wall 15 of the decorative sheet 7 can be bonded to the adjacent inclined peripheral wall 5 to connect the inclined peripheral wall 5.

  The horizontal width (W) of the inner surface adhesive portion 11 specifies the vertical width of the decorative sheet 7 bonded to the inclined peripheral wall 5. The width (W) of the inner surface adhesive portion 11 of the decorative sheet 7 bonded to the inner surface of the inclined peripheral wall 5 is set to, for example, 20% to 40% of the height of the inclined peripheral wall. For example, in the inclined peripheral wall 5 in which the height of (H) is about 4.5 cm, the lateral width (W) of the inner surface adhesive portion 11 is about 1.5 cm. Since the vertical width of the inner surface adhesive portion 11 specifies the position of the flange portion 10 at the upper edge of the inner container 3 to be described later, the lateral width (W) of the inner surface adhesive portion 11 considers the height of the inclined peripheral wall 5 and the storage amount. And set to the optimum value.

  The decorative sheet 7 is formed by laminating both end portions of the inner surface adhesive portion 11 at the inner surface of the boundary portion with the adjacent inclined peripheral wall 5, that is, the corner portion of the inclined peripheral wall 5, and thickening the inner sheet 3 by adhering to multiple layers. It can be reliably locked by the collar portion 10 and can be prevented from coming off. This is because the collar portion 10 of the inner container 3 engages the corner portion with the decorative sheet 7 that is laminated and adhered thickly, thereby preventing the inner container 3 from coming off.

  The decorative sheet 7 shown in the development view of FIG. 3 is provided with protrusions 16 protruding from both end edges of the inclined peripheral wall 5 to be bonded at both ends of the inner surface adhesive portion 11, and the protrusions 16 are laminated to form an inclined peripheral wall. Adhere to the inner surface of the 5 corner. In the development view of FIG. 3, a boundary line where the inner surface adhesive portion 11 is bonded to the inclined peripheral wall 5 is indicated by a chain line (A). The inner side of the boundary line indicated by the chain line (A) is bonded to the inner surface of the inclined peripheral wall 5, and the protrusion 16 on the outer side from the boundary line (A) is laminated and bonded to the inner surface of the adjacent inclined peripheral wall 5. Since the inclined peripheral wall 5 gradually increases in length in the longitudinal direction (L), the region where the inner surface adhesive portion 11 is bonded to the inner surface of the inclined peripheral wall 5 is longer in the longitudinal direction toward the outer edge of the inner surface adhesive portion 11. The dimension and the vertical width (D) are gradually narrowed. The decorative sheet 7 shown in the development view of FIG. 3 is provided with a protruding portion 16 on the outer side from the boundary line (A) with the longitudinal width (D) of the inner surface adhesive portion 11 gradually increased toward the outer edge. The protruding portion 16 is laminated and bonded to the corner portion of the adjacent inclined peripheral wall 5 to more reliably lock the corner portion of the flange portion 10 provided in the inner container 3.

  The decorative sheet 7 shown in the developed view of FIG. 3 is provided with a protrusion 16 with the longitudinal width (D) of the inner surface adhesive portion 11 gradually widened toward the outer edge. The protrusion 16 can be provided outside the boundary line with the same width without increasing the vertical width (D) of 11 toward the outer edge. This is because the boundary lines at both ends of the inner surface adhesive portion 11 gradually approach and narrow toward the outer edge, as indicated by the chain line in FIG.

  The lid 2 also bonds the decorative sheet 7 bonded to the outer surface of the top plate and the peripheral wall 6 to the inner surface of the peripheral wall 6. The inner surface of the top plate is painted, or another decorative sheet 7 is bonded to finish the surface.
