Description

  The present invention relates to an accessory device that is detachably mounted on a storage box that stores a roll of sheet-like material such as a wrap film for food packaging, aluminum foil, and cooking paper, and is particularly necessary outside the box. The present invention relates to an attachment device including a cutting blade for cutting a sheet-like material drawn out by a length.

For example, as a storage box for storing a wrap film wound in a roll shape, various structural forms have been proposed (see, for example, Patent Document 1 and Patent Document 2).
A conventionally known general storage box has, for example, a substantially square shape in a side view in which a roll body of a wrap film wound in a roll shape is stored, as disclosed in Patent Document 1. It is formed in a horizontally long substantially rectangular tube shape (square column shape). Then, the wrap film drawn out by the required length from the opening provided on one side of the four sides is cut by a metal cutting blade (cutting blade) provided on a lid that opens and closes the opening. By doing so, a wrap film having a required length is repeatedly supplied.

By the way, in recent years, sorting and disposal of garbage has been widely used. As a part of this, it is desired that a used storage box be separated and discarded by removing a metal cutting blade from a paper storage box.
JP 2000-190957 A JP 2008-150107 A

  However, the cutting blade is firmly attached to the storage box by piercing and bending with a claw provided on the cutting blade side. Moreover, the cutting blade cannot be grasped and cannot be easily removed because the cutting edge only slightly protrudes from the edge in the long side direction of the storage box or lid.

Therefore, conventionally, the cutting blade and the storage box are separated by tearing the storage box itself near the cutting blade or by grabbing the cutting edge of the cutting blade with a gripping tool and forcibly removing the cutting blade from the storage box. However, there was a risk that the cutting blades would bounce vigorously and hurt hands.
As described above, conventionally, it is difficult to remove the cutting blade from the storage box, and it is difficult to separate and discard, and there are problems such as danger, and countermeasures have been desired.

  Therefore, the present invention was devised in order to solve the above problems, and without attaching a cutting blade to the storage box, it is possible to cut the sheet-like material drawn out from the storage box in the same manner as known, In addition, the storage box can be used repeatedly for a plurality of storage boxes, and further has a locking structure that is simple in structure but cannot be removed carelessly when mounted on the storage box. It is to provide an auxiliary device for use.

In order to solve the above-mentioned problem, in the present invention, an attachment device is detachably attached to a storage box that stores a roll body of a sheet-like material that is pulled out of the box and cut.
A blade holder that is detachably attached in the long side direction along the outer corner of the storage box, and is fixed along the long side direction of the outer surface edge of the blade holder, and is pulled out from the storage box. A blade that cuts the sheet-like material, and the blade portion holding body is arranged along at least two wall surfaces of the four wall surfaces of the storage box having a substantially square shape in a side view. It is characterized by having a locking means that is formed in a substantially L shape in a side view to be applied and that is detachably locked to the two wall surfaces.
Here, the locking means is a lock that is removably locked with respect to locking slits that are long in the long side direction of the storage box on the two wall surfaces of the storage box. A stop projection piece is preferable.
The locking slit is opened with the opening position of one of the two wall surfaces shifted in the long side direction of the storage box relative to the opening position of the other wall surface. The protruding base portion of the locking projection piece that is locked to the locking slit of the wall surface is opened to sandwich the wall surface across the opening edge of the locking slit with a length corresponding to the positional deviation. It is preferable that a locking recess is provided.

According to such a configuration, the cutting blade that cuts the sheet-like material drawn out of the storage box to the blade holder that is attached to and detachably attached to at least two of the four wall surfaces of the storage box. Is attached. Thereby, since the cutting blade to the storage box side is unnecessary, it is possible to discard the used storage box with no sheet-like material as it is.
In other words, the storage box can be discarded without sorting, such as removing a cutting blade that is troublesome and dangerous, as in the conventional product.
In addition, the blade holding body is mounted on the outside of the storage box by inserting and locking the locking protrusion provided on the blade holding body side into the locking slit provided on the storage box side. Can do. At this time, after inserting the locking projection piece into the locking slit, the blade portion holder is shifted in the long side direction of the storage box, and is provided on the base side of the locking projection piece so as to sandwich the wall surface of the storage box. By locking the locking portion, the blade portion holder can be firmly attached to the storage box.
As a result, when the sheet-like object is cut against the cutting blade, the blade portion holding body may be inadvertently removed due to a force applied in the long side direction (longitudinal direction of the storage box) of the blade portion holding body. Can be prevented.

The attachment device for a storage box of the present invention is configured as described above, so that the blade holder is provided with a sheet-like material drawn out in the same manner as well known without attaching a cutting blade to the storage box. Can be cut with a cutting blade.
Moreover, when disposing of used storage boxes, there is no need to remove the cutting blades that are dangerous, and the length required when consumers repeatedly pull out and cut sheet-like items on a daily basis. The strength of the storage box against external forces such as torsional force and bending force in the side direction is strengthened by the blade holder, preventing the storage box from being damaged during use and being used repeatedly for new storage boxes. Can do.
As a result, the storage box does not require a cutting blade made of a metal material or the like, which requires a material cost and a production cost, and can be manufactured and provided at a lower cost.

  Moreover, in this invention, it is the structure provided with the cutting blade in the blade part holder attached so that it may be applied along at least 2 surfaces of a storage box, Therefore Although a structure is simple, it is a wall surface of at least 2 surfaces It can be attached to the storage box by a simple operation of inserting the locking protrusions into the locking slits provided in the storage box. Furthermore, in a state where it is mounted on the storage box, the locking recess provided on the protruding base of one of the locking protrusions locks the wall so as to sandwich the wall surface. It can be safely used in the same way as a storage box equipped with a cutting blade without being removed carelessly.
