Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a case for storing roll films, such as a wrap film, an aluminum foil, and a cooking sheet, which are mainly used for storing food in a kitchen.
[0002]
[Prior art]
Roll films such as wrap films for food packaging, aluminum foil, and cooking sheets are usually sold in paper boxes. A paper box is used as a storage case for a roll film, and is often provided with a metal cutter (saw blade) for pulling out and cutting a roll film having a multi-layered structure around a core by a required length.
When discarding after using up the film, it is necessary to separate the paper box and the cutter before discarding. However, the work of separating and discarding is troublesome and troublesome, and there is a possibility that a finger or the like may be cut accidentally. On top of that, it was often the case that all of the waste was discarded without being subjected to the above separation treatment and without being recycled.
[0003]
As described above, since the storage case for the wrap film is discarded as garbage after only one use, there is a problem of increasing household garbage and the like. Also, the case is not durable for repeated use and the cutter cannot be replaced.
In recent years, instead of a conventional paper container, a storage case has been proposed in which all the case components other than the cutter are made of plastic and the cutter can be easily replaced. (For example, refer to Patent Document 1).

Reference numeral 3 denotes an obscuring piece provided on the case body 1 and capable of opening and closing a film outlet 6 described later.
[0016]
The case body 1 and the caps 2a and 2b can be manufactured using a thin metal plate or a plastic material. In this embodiment, a thin metal plate is used.
As shown in FIG. 3, at least one end of the case body 1 is provided with a pair of L-shaped set grooves 4, and a pair of protrusions 5 which are inserted into and mesh with the set grooves on the side surface of the cap 2 b. Is formed. By inserting the projection 5 into the set groove 4 and fitting it to the end point of the set groove 4, the cap 2b is attached to the case body 1 without being accidentally detached during use. When removing the cap 2b, the cap 2b can be easily removed from the case body 1 by pulling out the protrusion 5 along the set groove 4. In this manner, the cap can be attached to the end of the case by a so-called bayonet method.
[0017]
In the longitudinal direction of the peripheral surface of the case body 1, an elongated opening functioning as a film outlet 6 is formed. Further, a film cutting table 7 having a right-angled triangular cross section provided with a film retaining section 9 shown in FIG. A crescent-shaped recess 8 is provided in the center of the cutting table 7. The concave portion has an effect of lifting the film from the surface of the cutting table, and makes it easy to grasp the film when taking out the film. A non-slip 24 is provided on the opposite side of the film outlet 6.
The film holding unit 9 is configured by attaching a sheet made of an adhesive material or a resin to which a wrap film is easily attached to the cutting table 7. Therefore, it is possible to prevent the cut end of the film from sticking to the sheet of the cutting table 7 after the film is cut, and prevent the film roll from rewinding.
[0018]
As shown in the figure, the cover piece 3 is provided so as to cover the cutout table 7, and is attached to the outside of the film take-out port 6 of the case body 1 by a hinge 10 so as to be openable and closable. Further, the cover piece 3 has a cutter setting groove formed at the tip, and a cutter 11 for cutting a film is sandwiched in the setting groove. Note that a metal saw blade is used as a cutter, and when the sharpness of the saw blade becomes poor, a new cutter can be used.
[0019]
Next, a method of storing a roll film such as a wrap film for food packaging, aluminum foil, and a cooking sheet in the case of the present invention will be described.
First, the cap 2b is removed from the storage case main body 1, the film roll FR is stored in the case main body 1 from the lateral side, the film end is pulled out from the outlet 6, and the end is put on the cutout table 7, 2b is fitted. When not in use, the covering piece 3 is closed to prevent dirt and foreign matter from entering.
[0020]
In use, the obscuration strip 3 is opened as shown in FIG. The film is picked up by using the concave portion 8 of the cutting table 7 and a film of a required length is drawn out. Then, while holding the covering piece 3 from above, hold the film end with the other hand and cut the film at a predetermined length. . By holding down the obscuring piece 3, the film is crimped to the cutting board 7 and adheres to the holding section 9 of the cutting board 7 to prevent the film roll FR from unwinding after cutting.
In addition, the film roll FR is guarded by the case body 1, so that there is no danger of the film end being pulled out or inadvertently jumping out of the case during use. The work efficiency is improved, and it is possible to meet the demand for work in a busy kitchen.
In addition, finding and peeling off the end of the film stuck to the roll is a particularly difficult task for a person with a disability or an elderly person. However, the end of the film is stuck to the film holding section 9 and is always easy to grasp. Keeping it in position makes it easy to use for people who have difficulties with detailed work.
Furthermore, in a kitchen or a kitchen, water or oil is easily scattered during use, but the metal or plastic storage case of the present invention, which has resistance to water and oil, uses a film roll in the case from water or oil. Protect and the case body can withstand repeated use.
