Description

  The present invention relates to a tray-like paper container for use in foods such as confectionery and toiletry individual packages such as soap, and is composed of a rectangular blank made of paperboard or corrugated paper that does not waste material. Related to paper trays.

  Traditionally, trays mainly used to improve the appearance of products and prevent rattling during vibrations are used for foods such as confectionery and toiletry individual packages such as soap, which are neatly aligned. Plastic products have been widely used because they can be easily molded even in complex shapes. However, in recent years, there have been problems such as environmental problems associated with disposal and incineration after use, and price problems due to soaring crude oil prices.

  Recently, paper trays with few such problems have begun to be used. However, in order to improve the appearance and prevent rattling during vibration, molding is performed using a plurality of members in order to provide a partition inside. In some cases, the manufacturing process may be complicated, and it may be difficult to disassemble.

  For this purpose, a number of paper containers with various partitions, which are made of paperboard blanks with no waste of material, have been proposed.

  For example, in Patent Document 1, a flat rectangular parallelepiped tray-shaped paper container made of rectangular blanks such as paperboard and corrugated paper, and having a monolithic dividing partition with excellent self-standing stability, A conventional double-walled paper container with a dividing partition, in which a double side wall is formed by folding a side plate and an internal dividing partition plate is mounted with a separate partition, has been introduced.

  The conventional paper container introduced here creates a separate partition plate separately from the blank that forms the main body to assemble the internal partition plate by attaching a separate partition. In addition to the troublesome process of fitting, there is a problem with the stability of the separate partition, and it is necessary to attach this separate partition to the bottom plate of the paper container. It was a paper container with a partition that took a lot of time and effort.

  Therefore, Patent Document 1 is a self-supporting one-piece rectangular blank made of paperboard, corrugated paper, or the like that contains vegetables, fruits, fishery products, various parts, and the like. As a paper container with a divisional partition with an integrated structure with excellent stability, in a flat rectangular tray-shaped paper container, the surrounding double side wall is formed by folding the side plate, and the inner dividing partition plate is turned by folding the bottom plate A double-walled paper container with a formed partition has been proposed.

  Moreover, in patent document 2, as a partition set in the inside of a gift box, in the gift box mount which forms the peak part for large partitions with a top crease line and a valley crease line on the both sides, A gift box divider has been proposed in which a plurality of substantially rectangular partition plates and tongue pieces connected at valley crease lines are provided along with each other, and the partition plates are raised and fixed. .

Moreover, in patent document 3, by comprising a container and a partition by one board, the troublesomeness which assembles a partition or fits into a tray is eliminated, and as a partition structure which has a certain amount of depth in a partition, After folding the plurality of flaps so that they are raised from the bottom of the paper box in which a blank having a plurality of flaps surrounded by cut lines is formed on the bottom surface, a thermoplastic sheet is vacuumed on the inner surface of the paper box. A partition structure in which a paper box and a thermoplastic sheet are integrally molded by a molding method such as a molding method and the flap is used as a partition has been proposed.

  Further, in Patent Document 4, the inner partition is firmly fixed to the paper box, has a height as the inner partition, and can be caused by being surrounded by the cut line and the crease line as an easily assembled paper box with the inner partition. It is equipped with two middle partition forming plates with multiple partition pieces, the bottom plate is connected to the flap at the bottom of the side plate, the partition piece is caused when the box body is raised, partitioning the inside of the box body, and the bottom plate is caused In the paper box with an intermediate partition that forms the bottom of the box body, the central partition plate is provided with a center plate that can be raised on the bottom plate side surrounded by the fold line and the cut line on the bottom plate side when the box body is assembled. A paper box with a partition which is engaged with each other so as to overcome the notch has been proposed.

  Although the structures proposed in Patent Documents 1 to 4 are excellent in that a paper container with a partition can be made from a single paperboard blank, it is suitable for foods such as confectionery and toiletry individual packages such as soap. It was not always suitable as a tray structure for the purpose of improving the appearance of products and preventing rattling during vibrations by using them and aligning them properly.

  The method of separating and aligning individual products with a partition prevents the material required for the partition plate from being increased, and it may take time to assemble and load the product after assembly, but prevents contact during transportation of individual products. This is a reliable method.

  However, as a paper tray for the purpose of improving the appearance of products and preventing rattling during vibrations, especially when foods such as confectionery and toiletry individual packages such as soap are inserted, patent documents Even if the structures proposed in 1 to 4 were used, sufficient usability and effects could not be obtained.

  In addition, the method of arranging a plurality of individual products in a tray and arranging them regularly without creating a gap between them improves the appearance of the product without using a partition, and prevents rattling during vibration. This is a normal method that can prevent sticking.

  For this reason, it has also been conventionally practiced to prevent gaps between individual products by allowing products stored with the side plates of the tray tilted slightly outward rather than perpendicular to the bottom so that they are close to the center of the tray. I came. Such a structure of the tray is easily possible with a plastic molded product, but it is difficult to clear problems such as environmental problems associated with disposal and incineration, and price problems due to rising crude oil prices. It is also difficult to easily assemble a side plate that is inclined outward from only one paper blank.

  As described above, it has been difficult in the past to make a paper tray that can arrange and arrange the individually packaged products from a single paperboard blank using the space created by the tray.
