Description

  The present invention relates to a paper tray used for foods such as confectionery, and individual packaging of toiletries such as soap, and is made of a rectangular blank with no waste of one sheet such as made of paperboard or cardboard, and is easy to align. The present invention relates to a flat rectangular tray-shaped paper container.

  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. In recent years, problems such as environmental problems associated with disposal and incineration and price problems due to soaring crude oil prices have arisen.

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

  Therefore, conventionally, various paper containers with a partition made of a rectangular blank that does not waste one sheet have been widely used.

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

  This paper container is formed by attaching a separate partition to the internal divided partition plate, creating a divided partition plate separately from the blank forming the main body and inserting it into the assembled main body. There is a problem with the self-supporting stability of the separate partition as well as the need, and it is necessary to stick this separate partition to the bottom plate of the paper container. It was a paper container.

  Therefore, in Patent Document 1, a self-supporting stability made of a rectangular blank that contains vegetables, fruits, marine fish and shellfish, various parts, etc., and is made of paperboard or corrugated paper, which is not wasteful. As a paper container with a dividing partition, which is an excellent integrated structure, 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 formed by folding the bottom plate A double-walled paper container with a divided partition has been proposed.

  Further, in Patent Document 2, as a gift box partition, a gift box mount that forms a large partition mountain by a top crease line and a valley crease line on both sides thereof, a plurality of creases along the valley crease line There has been proposed a gift box partition that is provided with a substantially rectangular partition plate and a tongue piece that is connected in a valley crease line, and the partition plate is raised and fixed so that the partition plate can be raised with one touch.

Further, in Patent Document 3, the container and the partition are formed of a single sheet of paper to eliminate the inconvenience of assembling the partition and fitting it into the tray, and the partition structure has a certain depth in the partition. After folding a plurality of flaps so that a plurality of flaps surrounded by a line are formed on the bottom surface, the plurality of flaps are bent up from the bottom surface, and then a thermoplastic sheet is vacuum-formed on the inner surface of the paper box A partition structure has been proposed in which a paper box and a thermoplastic sheet are integrally formed by a molding method such as the above method, and the flap is used as a partition.

  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 is a reliable method in terms of preventing contact during transportation of individual products, but increases the amount of material required for the partition plate, and product loading after assembly and assembly. However, there are still problems such as the fact that the vertical partition for arranging products in multiple stages is nothing but manual work for the time being.

  Paper trays for the purpose of improving the appearance of products and preventing rattling during vibrations, especially when foods such as confectionery and individual toiletry packages such as soap are loaded in two or more stages. As a result, even if the structures proposed in Patent Documents 1 to 4 were used, sufficient usability and effects could not be obtained.

  The method of arranging multiple items of the same size into a tray and arranging them regularly without creating a gap between them improves the appearance of the product without using a partition and improves the appearance of the product during vibration. This is a normal method that can prevent rattling.

  For example, when the number of products to be stored is exactly the number that fits in a rectangular box, it is sufficient that the paper tray that stores them is simple, for example, when 12 confections of the same size are stored in two stages If so, it is sufficient to prepare a rectangular parallelepiped tray that can be placed in 2 x 3 x 2 rows.

  Even if it is not a rectangular parallelepiped tray, the shape is not limited, but usually a rectangular parallelepiped is often preferred because of the ease of handling and the need for stacking.

  In such a case, as a tray, a dummy product with the same size as the inner dimension that is insufficient to form a rectangular parallelepiped in order to improve the appearance of the product and prevent rattling during vibration. There is a way to replace it.

  In this way, even when 10 pieces of individually packed confectionery of the same size are stored in two stages, the outer size is a rectangular parallelepiped as in the case of storing 12 pieces, and by eliminating the gap around the confectionery of the individual package. The above objective can be achieved.

However, it is difficult to prepare dummy products of the same size, and it is possible to pack cushioning materials instead. However, it is difficult to completely prevent rattling from being deteriorated in appearance. For this reason, it is normally possible to use a space formed by the tray itself, instead of filling a space portion that is insufficient for alignment with a dummy product or cushioning material.

  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.

Japanese Patent Laid-Open No. 10-147329 JP 2000-185730 A JP-A-9-267825 JP-A-9-272530

  In particular, one piece that can improve the beauty of the product and prevent rattling during vibrations when a package of toiletries such as confectionery and soap and other toiletries is placed in two or more stages. It is an object of the present invention to provide a paper tray that can be made from a paperboard blank.

  The paper tray according to claim 1 of the present invention is a paper tray formed by assembling a single blank, wherein the bottom plate is rectangular and the side plates rise and are formed on the four sides of the bottom plate. A base plate parallel to the bottom surface from at least one side plate of the side plate is provided via a fold line, and a standing plate parallel to the side plate from the base plate via the fold line and connected to the bottom plate via the fold line is provided. A paper tray is provided.

  The paper tray according to claim 2 of the present invention has a stop plate provided continuously with at least one side of the base plate between the side plate and the upright plate. It is.

  The paper tray according to claim 3 of the present invention is characterized in that a continuous top plate that is bent so as to cover the upper portion of the tray is provided on an upper portion of the side plate on which the base plate is not provided. The paper tray according to claim 1 or 2.

  The paper tray according to claim 1 of the present invention is a paper tray formed by assembling a single blank, wherein the bottom plate is rectangular and the side plates rise and are formed on the four sides of the bottom plate, and rises. A base plate parallel to the bottom surface from at least one side plate of the side plate is provided via a fold line, and a standing plate parallel to the side plate from the base plate via the fold line and connected to the bottom plate via the fold line is provided. By being provided, the space below the base plate formed by the base plate and the standing plate effectively fills the space between the products as an alternative to the space formed by the dimensions of the individual packaged products, such as confectionery When the individual package of toiletries such as food and soap is loaded in multiple stages of two or more stages, it is possible to improve the appearance of product alignment and prevent rattling during vibration.

  Further, since the paper tray is composed of only a portion of the paperboard blank that is connected via the folding line, it is possible to provide a paper tray that can be easily produced without waste of materials and processes.

As a result, without preparing dummy products with the same dimensions or packing cushioning material, the space portion that is insufficient for alignment can be formed by the tray itself, and this space can be used even if the product cannot be placed in a rectangular parallelepiped shape as it is. By using the part, it has become possible to provide a paper tray that is both aesthetically and functionally superior.

  Furthermore, instead of the plastic products that have been used, it is possible to provide paper trays that are easy to recycle and less environmental problems associated with disposal and incineration, because they can be easily molded even in complex shapes. It was.

  Since the paper tray according to claim 2 of the present invention has a stop plate provided continuously to at least one side of the base plate between the side plate and the upright plate, a space formed on the lower side of the base plate. In order to prevent the product from entering, the load of the product arranged on the other base plate serving as a stopper is supplementarily supported to prevent the product arrangement from being collapsed.

  In the paper tray according to claim 3 of the present invention, the top surface of the tray is provided on the top of the side plate on which the base plate is not provided. It serves as a lid for the bag and protects the stored items and maintains the shape of the bag when the product is stored in a tray and placed in a soft bag, that is, it is effective as a strength aid for holding a rectangular parallelepiped shape. .
