Description

  The present invention relates to a folding container having enhanced rigidity composed of a single container forming sheet.

Box-shaped containers formed by folding and assembling sheet-like materials as described in Patent Document 1 and Patent Document 2 have been used for various purposes.
Japanese Utility Model Publication No. 6-76025 Noto 3094811

  However, the conventional folding container is generally formed by folding and assembling the bottom part mainly composed of a flat surface and the side part surrounding the periphery, but as a result, the rigidity of the container itself is insufficient and the shape is stable. Difficult to hold.

  The folding container of the present invention aimed at solving such problems is a bottom surface portion, a bottom surface portion composed of a curved sheet whose outer peripheral line bulges outward on a sheet of waterproofed paper or resin. Adjacent to the basic structural surface of the container comprising the outer peripheral edge of the container connected as an inner line and a fold line, and the peripheral part connected to the outer line of the side part bulging outward like the inner line as a fold line By setting a fold part between the side parts, with the side edge line of the side part and the bisector of the angle sandwiched between these side lines as the fold line, the bottom part, side part, peripheral part, and fold part are seamless. It will be continuously and integrally developed, and by sequentially folding each of these surface portions along each fold line, the bottom surface portion and the side surface portion that share the fold line, and the side surface portion and the peripheral portion are curved surfaces acting on each other. The shape of the container itself At the same time, the peripheral part that forms a curved surface in the outward downward direction enhances the rigidity of the container opening and suppresses the force that the folding part tries to restore to the deployed state by sandwiching the folding part between the side parts. Thus, the folding container is improved in handling by maintaining a stable shape.

  Polygonal connecting pieces provided at one end of the adjacent peripheral part are folded back 180 degrees, the other peripheral part is rolled up, and inserted between the folded outer peripheral part of the folded part, and each surface part constituting the container The folding container is designed to improve the handleability by suppressing the force to restore the unfolded state and securely holding a stable shape even when the container is loaded.

  A connecting piece comprising a semicircular hole and a symmetrical semicircular cut is provided at each end of the adjacent peripheral edge, and the semicircular connecting piece is inserted into the other semicircular hole to form a container. By suppressing the force that each surface portion tries to restore to the unfolded state, the folded container is improved in handleability by reliably holding a stable shape even when a load is applied to the container.

  The container structure surface that is curved by folding it draws out the elasticity of the material and keeps the bottom and side surfaces that share the fold line part, and the side and peripheral parts in tension. This contributes to improving the rigidity of the container and provides a stable use situation.

  The outer peripheral downward curved surface strengthens the rigidity of the container opening, and at the same time, sandwiches the folded part between the side part and the force that the folded part tries to restore to the unfolded state. It also plays a role of deterrence and holding the shape. As a result, when the container is used as a container under a light load, an additional fixture can be omitted.

  By being formed from a single sheet that is continuously and continuously developed without a break, it can be used as a waterproof container that prevents liquid leakage.

  The contact of the curved bottom surface with the table or the like becomes a point or line contact, and by reducing the contact area, an effect of minimizing the temperature change of the contents due to the heat radiation effect from the bottom surface can be expected.

  As a result of the configuration in which the inner surface of the container continues to the surface of the peripheral edge, the thickness of the container is increased, and the expression as a container having a three-dimensional feeling different from the flat impression of the conventional product is possible.
