Description

  The present invention relates to a roll-shaped article storage box that stores a roll-shaped article in which a sheet-like material is wound around a cylindrical core.

  For example, various types of wrap film storage boxes are conventionally known as roll-shaped article storage boxes for storing roll-shaped articles in which a sheet-like material is wound around a cylindrical core. A storage box main body for storing a shaped article, and a lid provided integrally with the storage box main body. In using such a roll-shaped article storage box, after lifting the lid, the sheet-like material wound around the cylindrical core is pulled out from the storage box body to a desired length, and the sheet It is common to cut an object with a saw blade attached to the bottom surface of the storage box body or the front wall of the lid.

  In recent years, from the viewpoint of cost reduction, the above-mentioned type of roll-shaped article storage box has been aimed at downsizing, and the cylindrical core around which the sheet-like material is wound has become smaller and thinner, and therefore the roll-shaped article itself has also been reduced in weight. Tend to. When the roll-shaped article thus reduced in weight is stored in the above-mentioned type of roll-shaped article storage box and used, even if there is no problem at the initial stage of use, When the sheet-like material that is lifted and wound around the cylindrical core is pulled out, there arises a problem that the roll-shaped article is easily lifted out of the storage box body. In addition, when the roll-shaped article is a wrap film roll, from the viewpoint of cost reduction, the wrap film itself is also intended to be thin, and the user who has awakened to environmental awareness does not contain chlorine and has a low specific gravity. Since wrap films made of polyolefin (polyethylene, polypropylene, etc.) materials have been frequently used, the above problems are more likely to occur in combination with the properties of the wrap film itself such as the degree of adhesion and the degree of peeling. Such a problem associated with the weight reduction of the roll-shaped article is that not only the sheet-like material having a desired length can be cut, but also when the roll-shaped article is a wrap film roll, the wrap film roll is dropped on the floor. This is not preferable in terms of hygiene.

  Therefore, a push-in part is provided on the side of the storage box body, and the push-in part is held by the adhesive margin bonded to this side so that the roll-shaped article does not jump out of the storage box during use. I do. However, in order to use such functions, it is necessary for the user to perform an operation such as pushing the pushing portion provided on the side surface of the storage box main body into the storage box main body to the roll-shaped article storage box. There were variations in the use of, and the expectation of the effect was weak.

  In addition, recently, when the roll-shaped article is stored in a storage box, the pushing portion is automatically pushed by a machine. However, when using conventional equipment, a pushing process for the pushing portion is newly added. In addition, it must be incorporated in the apparatus, and a great modification of the equipment is required.

In order to solve such a problem, a roll-shaped article storage box having a function of preventing the roll-shaped article from being lifted by a configuration other than the pushing portion has been proposed. As a roll-shaped article storage box having such a function, on the side of the storage box main body, connected to the upper edge of the storage box main body and bent along the inner surface through the folding line at the edge of the front reinforcing inner surface folding plate A holding piece that is continuously provided and extends inward of the storage box body is provided with its width direction facing up and down, and the lower edge of the holding piece comes into contact with the wrap film roll to hold the wrap film roll from rising and storing. A wrap film storage box is known that prevents the wrap film roll from jumping out of the box body (for example, see Patent Document 1).
