  The present invention relates to an optical product storage container for storing an optical product.

  2. Description of the Related Art Conventionally, optical products such as lenses are stored and transported in a highly airtight container that can be stacked in multiple stages (see, for example, Patent Document 1).

  For example, as shown in FIGS. 2 and 3, such a container 100 includes a flexible container body 101 and a lid member 102 formed by vacuum forming a sheet-shaped resin material.

  Among these, the container main body 101 includes a product placement portion 110 provided with a plurality of recesses 110a on which optical products are placed, and a main body side taper portion 111 that hangs down from the periphery of the product placement portion 110 in a tapered shape. The main body side tapered portion 111 is surrounded by a collar, and has a main body side collar portion 112 that supports the lid member 102 disposed on the upper portion.

On the other hand, the lid member 102 is provided with a cover portion 120 that covers the product placement portion 110 from above, and another container main body 101 (hereinafter referred to as the upper-stage side) provided on the upper-stage side. The container main body 101) and a rising portion 121 that is loosely fitted inside the main body side taper portion 111.

A container body support part 122 that supports the inner peripheral edge of the lower surface of the main body side collar part 112 on the upper surface, and a container body 101 that is suspended from the periphery of the container body support part 122 in a tapered shape and is disposed below A lid-side taper portion 123 that is inserted through the taper portion 111 inward and is fitted to the main-body-side taper portion 111, and a collar around the lid-side taper portion 123 It surrounds, and a cover-side flange portion 124 which is supported by the main body side flange portion 112 of the container body 101 that is disposed below, the.
JP 2004-238001 A

However, in the container 100 as described above, the upper container 100 is viewed from below only by the contact portion between the inner peripheral edge of the main body side collar portion 112 and the upper surface of the container main body support portion 122 in the lower container 100. When the container body 101 and the lid member 102 have some backlash due to design or processing reasons, the upper container 100 may have a backlash caused by, for example, skidding due to external pressure. 4, as shown in FIG. 4, as a result of the inner peripheral edge of the main body side collar portion 112 being easily removed from the upper surface of the container main body support portion 122, the upper container 100 collapses. Resulting in. 4 shows a state where the inner peripheral edge portion of the main body side collar portion 112 is detached from the upper surface of the container main body support portion 122 on the right side in the drawing.
Further, since the container body 101 and the lid member 102 are formed of a sheet-like resin material and have flexibility, the main body side taper portion 111 and the lid side taper portion 123 are also spread outward by external pressure. As a result of the inner peripheral edge portion of the side collar portion 112 being disengaged from the upper surface of the container body support portion 122, the container 100 on the upper stage side collapses. In this case, as shown in FIG. 4, not only the right side in the figure but also the left side, the front side, and the rear side, the inner peripheral edge portion of the main body side collar portion 112 may be detached from the upper surface of the container main body support portion 122. is there.
And the above problems are solved even if the thickness of the sheet-like resin material which forms the container main body 101 and the cover member 102 is changed as shown, for example in FIG. 5 (a)-(c). I can't.

  On the other hand, when the container main body support part 122 is expanded outward to prevent the collapse of the load, the width of the container main body support part 122 is increased, and the main body side taper part 111 and the lid side taper part 123 are fitted together to improve the airtightness inside the container 100. It cannot be secured, and the practicality as an optical product container is lost. In addition, if the container body support part 122 is widened inwardly to form a wider width, the gap between the outer peripheral surface of the rising part 121 and the inner peripheral surface of the main body side taper part becomes wider, and the positioning of the upper container body 101 is increased. Therefore, the side slip amount of the container body 101 is increased, and the collapse of the load is not prevented.
