Description

  The present invention relates to a pulp mold container formed by integral molding with a pulp material.

  Conventionally, it is a pulp mold container that is integrally formed of pulp material, and a lid is connected to the container body with a hinge on one side, and the lid is closed on the container body by folding the lid from the hinge. As a container made from a pulp mold to do, what was described in patent document 1 (Unexamined-Japanese-Patent No. 2013-233935) and patent document 2 (Unexamined-Japanese-Patent No. 2012-158371) is known, for example.

  In the pulp mold container described in Patent Document 1, a locking hole is formed in the side surface of the lid, and a locking protrusion is provided in the hole, and a receiving plate is continuously provided on the same side surface of the container body. , A convex portion whose lower surface side is open is formed on the backing plate, and when the lid is closed, the backing plate of the container body is overlapped on the inner side of the side surface of the lid body, and the convex portion on the backing plate side is placed in the locking hole on the lid side This is a structure that is fixed to the lid closed state by protruding from the bottom, engaging with the locking protrusion of the locking hole on the lower surface side where the convex portion is open.

  In the case of this conventional example, in order to make the convex part of the receiving plate on the container main body side protrude outward from the locking hole on the side surface of the lid body, the convex side of the container main body can be convex and concave by the protruding length of the convex part. There was a problem to see.

  Further, in the pulp mold container described in Patent Document 2, a latch receiving hole is provided on the side surface of the lid, and a latch plate is continuously provided on the same side surface of the container body. Protrusion is formed in the part corresponding to the hole, and when the lid is closed, the latch plate of the container body overlaps the outside of the side of the lid, and the latch plate projection is inserted from the outside into the latch receiving hole on the lid side. The structure is fixed so that it cannot be removed and is closed.

  Even in the case of this conventional example, there is a problem that it is necessary to open a latch receiving hole on the side surface of the lid.

  Furthermore, when considering the global environment, packages are necessary, but the burden on the environment is unavoidable. Therefore, considering the method of reducing the environmental load as much as possible, it is thought that a box that is not thrown away is the best. However, there is no immutable thing and eventually it will be thrown away. Therefore, there is a great demand for containers made of materials that are designed so that consumers do not want to throw them away as much as possible, and that the materials are made of materials that match the recycling-oriented society with reduced environmental impact.

  Pulp mold containers may meet such consumer demands. However, in producing such a container, how to fix the lid is a major issue in designing the container so that consumers do not want to throw it away.

  Conventional egg mold containers for egg packs have been crafted to be drilled or inserted with an insertion port for molding technology problems or function emphasis, or to be attached to the main body of the pulp mold container. There was no container that consumers wanted to reuse

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. A pulp mold container 10 according to the embodiment is an integrally molded product having a shape in which one side of a container main body 101 forming a lower half and a lid 102 forming an upper half are connected to each other by a hinge portion 103. Yes, it is integrally formed with the lid open as shown in FIG.

  The container main body 101 having an open upper surface has a structure in which a main body side flange 112 is formed on the periphery of the upper surface opening of the housing portion 111. Further, a fitting recess 113 is formed integrally with one side surface of the housing portion 111, in the center of the long side surface in the embodiment, so as to be recessed inside the housing portion 111. The shape and position of the fitting recess 113 will be described later.

  On the other hand, the lid body 102 has a structure in which a lid side flange 122 is formed on the periphery of the lower surface opening of the lid body 121. A fastening flap 123 is integrally connected to the long side portion of the lid side flange 122 opposite to the hinge portion 103 via a short hinge portion 124. The fastening flap 123 is integrally formed with a fitting convex portion 125 at a portion corresponding to the fitting concave portion 113 on the side surface of the container main body 101 when the lid is closed.

  In the pulp mold container 10 according to the embodiment, the lid 102 is raised from the lid open state shown in FIG. 2 by the hinge 103, and the lid shown in FIG. 1 and FIG. . In order to make the lid closed state shown in FIG. 3 to FIG. 1 and FIG. 4 autonomously and hold the state autonomously, a fastening flap 123 of the lid body 102 is hung downward from the outside on one side surface of the container body 101 side. The fitting convex portion 125 of the fastening flap 123 is pushed into the fitting concave portion 113 opened to the side on the container main body 101 side in a state of being pulled down so as to be elastically fitted.

  In order to autonomously hold this elastic fitting state, the fitting concave portion 113 and the fitting convex portion 125 are formed in the following formation positions and shapes. The fitting recess 113 formed on the side surface of the housing part 111 of the container body 101 has a shape in which the inclined surface 114 rises as it deeply enters the inside of the housing part 111 from the upper edge 113a of the opening. On the other hand, the fitting convex portion 125 formed on the fastening flap 123 of the lid 102 has an inclined surface such that the upper surface 126 in the fitted state is substantially parallel to the upper inclined surface 114 of the fitting concave portion 113.
