Description

  The present invention relates to a case made of wrapping paper that accommodates a relatively heavy product such as a connecting nail used by a power nailer or the like and holds the product so as not to be deformed therein.

  In general, when shipping products manufactured at the factory, the product is packed in a paper case and transported from the factory to the dealer and from the dealer to the user. When loading a case made on a pallet or a car, or carrying it from a car to a work site, an operator puts a hand on a paper case and carries it. However, since a general paper case is not formed with a concave portion or the like that is placed on the outer peripheral surface, it is difficult to handle a paper case containing a heavy product. In addition, some home appliances have an opening for forming a handle at the top of the paper case, and the paper case can be carried by inserting a finger into the paper case through the opening. . However, in paper cases that store heavy products such as connecting nails used in power nailers, the edges of the paper case opening are damaged by the weight, or the fingers are damaged by the edge of the opening. There was a problem such as.

In order to facilitate handling of the paper case containing such heavy objects, the upper and lower pieces are integrally formed via bent portions at the upper and lower ends of the side piece constituting the cylindrical case main body, In a paper case that is formed into a box shape by bending the upper and lower pieces inward, bent pieces are formed by cutting in the side piece and the upper and lower pieces in the portion corresponding to the space formed when the product is stored. A paper case has been proposed in which the folded piece is folded so as to protrude into the paper case, and the product stored in the paper case is stabilized by the folded piece. In the paper case formed in this way, a concave portion is formed on the outer side surface of the paper case by a folded piece folded toward the inside of the paper case on the side surface of the paper case, and a finger is inserted into the concave portion. The paper case containing the product can be easily handled.

  Furthermore, in connection fasteners such as connection nails used in power nailers driven by power such as compressed air, a number of metal fasteners are connected by a flexible connection body and wound in a spiral shape. The connecting fastener is accommodated in a cylindrical magazine formed on a tool such as a nail driver and is sequentially supplied to the driving portion by a feed mechanism formed on the tool. Therefore, if the cylindrical shape of the connecting fastener housed in a paper case or the like is deformed due to vibration during transportation or the like, the fastener cannot be supplied. Therefore, in a packaging container for storing such a connected fastener, a plastic tray having a large number of cylindrical recesses is used in order to prevent deformation of the connected fastener due to vibration during transportation. A plurality of connecting nails are accommodated therein, and a tray accommodating the connecting nails is stacked and accommodated in a paper case for packaging.

  In the conventional paper case, a pair of slits are formed on the shoulders of the two opposite sides of the box-shaped case with a space therebetween, and the bent pieces formed between the pair of slits are formed on the paper case. Since the concave portion is formed on the outer surface of the paper case by bending inward, openings that allow the inner and outer sides of the paper case to communicate are formed on both sides of the bent portion. Dust or water droplets or the like may enter the paper case containing the product, and may contaminate the product such as the connecting nail or the connected body, or may generate rust.

  In addition, conventional trays that store cylindrical products such as connecting fasteners in paper cases use plastic materials as the tray material, so disposal (incineration, etc.) when discarding trays after use is environmental. It may be a problem above. At present, from the viewpoint of protecting the environment, it is desired that plastic materials should not be used as much as possible. Also, since plastic trays are generally molded from a thin material, when transporting multiple connecting nails taken from a paper case to the work site, they cannot be carried on plastic trays. It was necessary to prepare another container such as a small box.
