DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jewelry article packaging case and a packaging case unit for accommodating jewelry articles for distribution or sale. The jewelry articles include rings, necklaces, piercings, earrings, brooches, and the like. All jewelry items such as pendants, pendant necklaces, and bracelets are eligible.

[0002]

2. Description of the Related Art Conventionally, when a jewelry store sells, for example, a pearl necklace or a diamond ring, it is common to put it in a packaging case and give it to a purchaser. However, the packaging case at the time of sale is discarded after purchase, or even if it is not discarded, if multiple jewelry items such as necklaces and rings are purchased, individual boxes (packaging cases) are bulky,
If these are individually used for storing jewelry articles, it takes up space and is difficult to organize. For this reason, it is common to buy a separate jewelry box and put it together.
Therefore, after all, the packaging case at the time of sale (or at the time of distribution) is often stored or discarded as unnecessary goods, which leads to waste of resources and increase of waste. In addition, while jewelry items are housed in a packaging case and sold for sale, certificates of such jewelry items such as certificates, certificates, and identification documents are handed separately from the packaging case. The buyer may lose the certificate during storage.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to use a jewelry article packaging case, which can be called a packaging material, when distributing or selling a jewelry article. An object of the present invention is to avoid the problem and increase the degree of utilization, and to prevent loss of a certificate such as a warranty card for the packaged article to enhance the integrity with the jewelry article.

A surface packaging holder that is detachably attached to the case main body so as to cover the opening of the case main body and holds the jewelry article to be distributed or sold for packaging, and a surface layer in the case main body. It is incorporated so as to be hidden under the package holder, forms a multi-stage structure of two or more layers together with the surface package holder, and forms an empty surplus storage space that does not store jewelry articles to be distributed or sold. After the role of the packaging is completed, a lower housing portion that can hide jewelry articles and other articles by being hidden under the surface package holder is included.

[0005] When selling jewelry articles, jewelry articles such as pearl necklaces and diamond rings are held on the surface package holder of the packaging case, and the lower housing section is generally in a state of an excess housing space having nothing. Thus, a packaging case containing such jewelry articles is provided to the purchaser. The purchaser receives the packaging case as a type of jewelry packaging, and after the purchase, holds the purchased jewelry article in the surface packaging holder and temporarily holds the surface packaging holder like a lid. The jewelry box can be used as a jewelry box by removing it and putting another jewelry item such as a necklace, a ring, an earring, or a pendant in the lower accommodating portion below the jewelry item. Therefore, even after the purchase of the jewelry article, the packaging case is less liable to be stored or discarded, and is easily used effectively. This results in social benefits such as saving resources and reducing waste.

[0006] By combining the above-mentioned packaging case and the following certificate, a packaging case with a certificate, in other words, a packaging case unit can be obtained. That is, a certificate such as a certificate of guarantee, a certificate of appraisal, or a certificate of discrimination of a jewelry item held by the surface package holding body, which substantially overlaps the back surface of the top cover, and is held detachably with respect to the top cover to open and close the top cover. This is a packaging case with a certificate that includes a certificate that follows. With this configuration, the certificate is held on the back side of the upper lid of the case body and follows the opening / closing operation of the upper lid, so that the loss of the certificate can be effectively prevented. In addition, if the certificate has a configuration in which a photograph, a picture, and other images representing the jewelry items held by the surface package holding body are arranged on the sheet surface facing the case body with the upper lid closed, the packaging is performed. A certificate appears on the back of the case as soon as you open the top lid of the case, and a photo showing the jewelry items in the packaging case,
Pictures and other images are immediately visible. Therefore, the relationship between the jewelry item and the certificate in the packaging case can be understood at a glance, and it is easy for the seller and the consumer to understand.
