Abstract

A film storage container includes a container main body having a storage space for storing a film roll therein and a pull-out opening formed in at least a part of the container main body in order to pull the film to the outside of the container main body from the roll stored in the storage space. The container main body has a top plate, a front plate, a bottom plate, a pair of side plates, and a rear plate. A protruding piece for fixing the top plate is inserted into a space inside a main body part formed by the front plate, the bottom plate, the side plates, and the rear plate. The film is provided with a cutting-starting point part that extends in a predetermined flow direction and is provided in a part other than an end part in a width direction substantially orthogonal to the flow direction.

First claim

1 . A film storage container comprising:
a container main body that has a storage space for storing a film roll therein; and a pull-out opening that is formed in the container main body in order to pull a film of the roll stored in the storage space to the outside of the container main body, wherein the film is torn in a width direction that is substantially orthogonal to a direction of the pulling from the pull-out opening in a case where a tearing force is applied thereto, the container main body has a top plate, a front plate, a bottom plate, a pair of side plates, and a rear plate, a protruding piece for fixing the top plate is inserted into a space inside a main body part formed by the front plate, the bottom plate, the side plates, and the rear plate, and the pull-out opening is formed in the top plate.

2 . The film storage container according to claim 1 , wherein:
the container main body is formed in a substantially rectangular parallelepiped shape, the pull-out opening is formed to extend in the width direction in one of the six surfaces of the container main body, a temporary holding part is provided to make an adhesive force or a frictional force act on the film pulled to the outside of the container main body from the pull-out opening so as to temporarily hold the film, and the temporary holding part is formed to extend in the width direction near the pull-out opening in the one surface of the container main body.

3 . The film storage container according to claim 2 , wherein a cut part is formed in the top plate, and the protruding piece is inserted into the cut part.

4 . The film storage container according to claim 2 , wherein the temporary holding part is an adhesive part that makes an adhesive force act on the film pulled to the outside of the container main body from the pull-out opening.

5 . The film storage container according to claim 4 , wherein the adhesive part is formed of a varnish coating layer.

6 . The film storage container according to claim 4 , wherein the adhesive part is formed of a double-faced tape.

7 . The film storage container according to claim 2 , wherein the temporary holding part is a friction part that makes a frictional force act on the film pulled to the outside of the container main body from the pull-out opening.

8 . The film storage container according to claim 7 , wherein the friction part is formed of a rubber material.

9 . A film comprising a cutting-starting point part that extends in a predetermined flow direction and is provided in a part other than an end part in a width direction that is substantially orthogonal to the flow direction.

10 . The film according to claim 9 , wherein gel fraction is 10 to 60 wt %.

11 . The film according to claim 9 , wherein the cutting-starting point part is at least one perforation.

12 . The film according to claim 9 , wherein the cutting-starting point part is a part subjected to embossing.

13 . The film according to claim 9 , wherein the cutting-starting point part is continuously formed in the flow direction.

14 . The film according to claim 9 , wherein the cutting-starting point part is formed inside the end part in the width direction by 25 mm or greater.

15 . The film according to claim 9 , wherein the cutting-starting point part is formed in a substantially central part in the width direction.

16 . A film roll that is formed by winding the film according to claim 9 .

17 . A film storage body comprising:
the film roll according to claim 16 ; and a container main body that has a storage space for storing the film roll therein, wherein the container main body has a protrusion for assisting the cutting of the film of the film roll.

18 . The film storage body according to claim 17 .
wherein the container main body has: a rectangular parallelepiped-shaped storage chamber with an opened upper part that is formed by wall surfaces including a front plate, a bottom plate, a rear plate, and side plates; and a lid body that is formed by wall surfaces including a lid plate that is provided to be connected in such a direction as to cover the storage chamber from an upper edge of the rear plate, a covering lid piece that extends in such a direction as to cover the front plate from a front edge of the lid plate, and side covering lid pieces that are provided on both sides of the covering lid piece, and the protrusion is provided at a tip edge part of the covering lid piece.

19 . A film storage body comprising:
the film roll according to claim 16 ; and a container main body that has a storage space for storing the film roll therein, wherein the container main body does not have a protrusion for assisting the cutting of the film of the film roll.

20 . A film cutting method comprising:
forming a through mark by poking a part of the cutting-starting point part of the film according to claim 9 with a finger; and tearing the film in the width direction from the through mark as a starting point.
