Description

The present invention relates to a sheet for an assembly type packaging box that can be assembled into a box shape, and an assembly type packaging box.

In recent years, as the world has been working on the SDGs, packaging has been reviewed, and efforts are being made to make containers and packaging more compact and to reduce the amount of plastic and paper used. An increasing number of products are being sold by switching from bottles to pouch containers with spouts to reduce their environmental impact. Furthermore, in the past, many products such as shampoo, body soap, and liquid detergent that were sold in pouch containers with spouts were sold as refill containers that could be refilled into dedicated bottles. However, in recent years, pouch containers with spouts have been used for cosmetics such as men's lotions and emulsions, facial soaps, seasonings such as soy sauce and miso, and alcoholic beverages such as wine and sake. It is becoming more and more common.

Furthermore, with the spread of online shopping, these products can be easily purchased over the internet. These products are often delivered using delivery services such as courier services.For example, when packaging items in glass bottles, a partition is placed inside the box body to separate the bottles. , a packaging box in which a cushioning inner plate is placed on the inner partition and then a lid is placed on the box body has been devised as a packaging box for bottles as disclosed in Patent Document 1. The packaging box for bottles of Patent Document 1 is a packaging box that has a general packaging form used when gifting a bottle containing alcohol, etc., and includes a box body, a lid, a partition, a bottom plate, and a middle plate. It is constructed as separate parts. In addition, a U-shaped pillow is formed at one end of the partition to support the head of the bottle, and by making a Y-shaped notch on the top of the pillow, the head of the bottle is When pressed, the notch opens downward and holds the bottle head in place.

Furthermore, as a corrugated cardboard envelope formed from a single corrugated sheet, a front panel part, a back panel part, a bottom gusset part, a side gusset part, a top gusset part, a side adhesive part, and a top adhesive part are provided. A corrugated cardboard envelope has been devised as disclosed in Patent Document 2, which includes a bottom corner sealing portion, and a top corner sealing portion. The thickness of the cardboard envelope disclosed in Patent Document 2 can be easily adjusted depending on the thickness of the contents to be shipped. In recent years, with the increase in the number of nuclear families and dual-income households, the percentage of people staying at home, especially during the day, has been decreasing. Therefore, as one means to solve the problem of decreased product delivery efficiency, cardboard envelopes such as those disclosed in Patent Document 2 are used, which allows the product to be directly placed in a mailbox or delivered to a mailbox. Additionally, using these mail delivery services has the advantage that shipping costs are lower than that of home delivery.
