Description

  The present invention relates to a packaging box used for packaging a fragile article such as a glass container.

  Conventionally, when a fragile article such as an ampoule or a glass container containing a chemical solution is stored in a paper box for packaging, a foam member or an air cap is provided in the gap between the paper box and the glass container in order to protect the article from an impact outside the paper box. In such a packaging format, it is necessary to prepare a separate cushioning material from the paper box, and the packaging process becomes complicated and packaging costs increase. A paper box that is assembled by folding a single blank plate has been proposed in which a buffer portion is integrally provided inside the paper box. Such a technique is disclosed in, for example, Patent Document 1. In the paper box of this document 1, a double structure is adopted on the entire top surface of the article storage space so as to protect the article from an impact outside the paper box.

  However, in the paper box of the above-mentioned document 1, since the lid buffer portion constituting the inner surface of the double-structured box is connected to the upper lid only at the end position close to the side surface of the article storage space, In the structure of the lid buffer part, the center part of the lid buffer part is easily bent when it is pressed, and a plurality of glass containers are placed horizontally, like an ampoule or other glass container containing a chemical solution. When stored in a line, it is difficult to obtain a sufficient buffering effect on the outer periphery of the glass container stored in the box. Therefore, in order to effectively prevent damage and dissipation due to external impact of the article, a packaging box having a buffer structure capable of obtaining a sufficient buffer effect inside the top surface has been devised, and this has been proposed in Patent Document 2. .

  The packaging box of this document 2 is assembled by folding a sheet paper box forming substrate, a lower box part with the top surface opened, an inner lid part for closing a part of the top surface, and an inner lid An upper lid portion that covers the portion from above and closes the top surface, and the inner lid portion is formed by a buffer portion forming plate in which an abutting portion, a connection support portion, and an inner lid plate are sequentially arranged via a broken line. . In this case, the contact portion is held at a predetermined distance from the inner lid plate by the connection support portion, and the inner lid portion is formed in a double structure. The connection support portion is disposed at a contact position between the contact portion and the article (preferably at a substantially central portion of the top surface), and has a length that reaches from end to end of the articles arranged in a row. In this way, the abutment surface is provided so as to be substantially parallel to the top surface and at a predetermined distance from the top surface, and a part of the top surface is configured in a double structure, and the contact surface and the article are in contact with each other. Since the contact surface is connected to the support surface at the contact position, the contact surface is elastically supported by the support surface at the position where the support surface is provided, and the contact portion is less likely to bend, A sufficient buffering effect is obtained against impact from the outside, and damage and dissipation of the article can be effectively prevented.

A U-shaped buffer space is defined. That is, the first article outer peripheral part protective surface is stretched and supported by the first article outer peripheral part protective surface support part fixed between the first article outer peripheral part protective surface and the inner side surface of one surface of the box. Therefore, the protective surface is difficult to bend, and since the first article outer peripheral part protective surface support part has a spring action, the entire protective surface has sufficient elasticity. In order to obtain a sufficient buffering effect, there is no need to connect the contact surface to the support surface at the contact position between the contact surface (in the case of the present invention, the article outer peripheral portion protection surface) and the article. Therefore, the position of the support surface is not limited at all, and the degree of freedom in designing the inner lid portion (one surface of the box in the present invention) is not limited. The second article outer peripheral part protective surface has the same effects as the first article outer peripheral part protective surface. And in the case of this buffer part, a 1st goods outer peripheral part protective surface and goods are passed through the substantially U-shaped buffer space along each inner surface of one side of the box, the other side, and the other side inside the box. Since the bottom protective surface and the second article outer peripheral protective surface are arranged, the outer peripheral part of the article stored in the box, the outer peripheral part on the opposite side, and the three surfaces facing the bottom part have a double structure. In particular, in a packaging such as an ampoule or other glass container that contains a chemical solution, the buffering effect is further increased, and damage to the article can be more reliably prevented.
