DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper box for storing wrap film with a take-up and locking piece for home use, such as a roll of aluminum foil or a resin film.

[0002]

2. Description of the Related Art Conventionally, a metal or paper saw blade is used in which one end of a wrap film, such as a rolled aluminum foil or a resin film, housed in a paper box is pulled out and cut to a required length. Is a widely used rectangular parallelepiped wrap film storage paper box.

[0003] Conventionally, in the above-described horizontally-long rectangular parallelepiped wrap film storage paper box, for example, in order to prevent the wound wrap film from jumping out when one end of the wrap film is pulled out to a required length and cut. JP-A-63-5
In Japanese Patent No. 5044, left and right side plates (31,
The invention in which a U-shaped cut line (11) with a fold line (d) is provided at the center portion of 31) is disclosed.For example, in Japanese Utility Model Laid-Open No. 2-87728, As shown in FIG. 6, an L-shaped opening (71) and three fan-shaped fastening pieces are provided on each of the two glue margin pieces (21, 41, 21, 41) on the left and right. (13,14,15) is disclosed.

[0004]

However, for a horizontally long rectangular parallelepiped wrap film storage paper box provided with a U-shaped cut line (11) with a fold line (d) shown in FIG. Although winding and locking pieces can be easily formed simply by cutting and bending the score line (11), the formed winding and locking pieces such as the crease line (d) returning when the wrap film is pulled out and cut, etc. A rectangular parallelepiped having problems with strength and stability and having an L-shaped opening (71) and three fan-shaped locking pieces (13, 14, 15) shown in FIG. Wrap film storage paper box, two fan-shaped locking pieces (13,14)
Is fitted into the L-shaped opening (71) and has excellent strength and stability, but once opened, two fan-shaped locking pieces (13, 14) are opened in the L-shape. (71) It is necessary to insert and form a winding stop piece, and it takes time and effort to form the winding stop piece. There is a need for a wrap film storage paper box with a winding and locking piece that has excellent stability.

[0005] In view of the above demand for a wrap film storage paper box with a take-up and locking piece for home use, the present invention, as shown in FIG.
