Description

[Detailed explanation of the invention] [Industrial application field] This invention uses metal foil such as aluminum foil,
To store a long roll of paper or plastic sheet or film (hereinafter collectively referred to as "film"). This case concerns the following cases.

[Conventional technology]

The case is shaped like a rectangular column to store a long film wound around a hollow core.The top of the case is a lid that can be opened and closed, and the front end of the lid has a hole inside the case. It is well known to have a bent part that can be inserted. An incisor is provided on the upper edge of the front surface of the case into which this bending part is inserted, and the film pulled out to a desired length from the film roll stored in the case is folded against the incisor and pulled. cut by. Since the film is normally pulled out and cut with the lid of the storage case open, the entire film roll flies out of the case when the film is pulled out, which is extremely undesirable for the removal operation. In order to prevent the entire scroll from flying out, various proposals have been made in the past, but the simplest and most typical one is to remove the protrusions that protrude into the openings at both ends of the core of the scroll from the inner surface of the side wall of the case. There are known means for forming. However, when forming a protrusion in this way and inserting it into the winding core, during use,
When you need to take out a scroll from its storage case,
There is an inconvenience that this removal is not possible. Furthermore, there is a problem in that there are various design restrictions regarding the shape and size of this protrusion.

[Means for solving problems]

The present invention solves the above-mentioned problems in the prior art by making it possible to draw out film with the case lid closed, without having to open the case lid as in the conventional film drawer for rolls. .

That is, the gist of the present invention is to provide a case for storing a roll of a sheet or film that is inserted into the front inner side of the case, in which the folded insertion part continuing from the front end of the lid part on the upper surface of the case has incisors on the upper edge. An opening window is provided that passes through approximately the center of the boundary line between the lid and the folded insertion part and extends from the lid to the folded insertion part, or a perforation is provided to serve as this opening, and the front surface of the case Further, the storage case is provided with an opening window corresponding to the opening of the folded insertion part or with a perforation serving as the opening window.

Next, embodiments of the present invention will be described with reference to the accompanying drawings.

〔Example〕

Figure 1 is a schematic perspective view of an example of the case of the present invention;
The figure is a schematic cross-sectional view showing the essential parts of the present invention taken along the line of FIG. 1, and FIGS. 3 and 4 are explanatory diagrams showing the operation of pulling out the film from the roll housed in the case of the present invention.

In the figure, 1 is a case, 2 is an incisor, 3 is a lid on the upper surface of the case 1, 4 is a folding insert provided following the front end of the lid 3, and 5 is a link between the lid 3 and the folding insert 4. The boundary line 6 is the front side of the case 1, and the bent insertion part 4 is inserted into the upper back side thereof. Reference numeral 7 denotes an opening window provided approximately at the center of the boundary line 5, partially penetrating into the lid portion 3 and partially penetrating into the folded insertion portion, and numeral 8 indicating an opening window provided above the front surface 6. When the bent insertion part 4 is inserted, it is provided at a position corresponding to the opening of the opening window 7, as shown in FIG. 9 is a film roll, 10 is a film roll 9
11 is the tip of the film roll 9, and 12 and 13 are fingers.

Next, the operation of pulling out a desired length of film from the film roll housed in the case of the present invention and cutting it will be explained.

Initially, the end of the film is pulled out of the case and cut by placing it against the incisors 2, but after the cutting is done, the tip of the film is at the same position as the upper end of the incisors 2. When the next film is to be pulled out, the film is pulled out with the lid 3 of the case kept closed, that is, in the state shown in FIG. As shown in FIG. 2, an opening window 7 is opened on the side of the lid part 3 that contacts the incisors 2, and an opening window 7 and an opening window 8 of the front surface 6 overlap on the upper side of the front surface 6 of the case. As shown in FIG. 3, the fingers 12 are inserted into the opening window 7 of the lid part 3 and the opening window 8 of the front face 6 to remove the tip part 11 of the film. Gradually slide it upwards. Then, the tip of the film 1
1 will come out of the case from between the incisors 2 and the folded insertion part 4, so pinch that part with your fingers 12 as shown in Fig. 4 and pull it out, until the desired length comes out. The film is folded and cut by the incisors 2. Thereafter, the same operation can be repeated, and the film can be pulled out and cut with the lid 3 of the case kept closed.

The opening windows 7 and 8 are not opened in advance,
Perforations may be made in the lines forming the periphery of these opening windows so that the opening windows can be easily formed by pushing or pulling with fingers. In this case, the case is not opened until it reaches the end user, and it is possible to prevent dust from entering the case. In the present invention, perforations are defined not only when small holes are provided in series, but also when very short linear cuts are made in series in the length direction at slight intervals.
Alternatively, it may be of any form that can be easily opened with just a fingertip, such as the above-mentioned linear cuts and small holes provided alternately in series at intervals, and the present invention encompasses these. It is something.

Further, the opening windows 7 and 8 are formed in advance,
To prevent dust from entering, an easily peelable sticker may be attached. As described above, other embodiments that are obvious to those skilled in the art can be adopted without departing from the gist of the present invention.

The storage case of the present invention is advantageously used for storing rolls of metal foil such as aluminum foil, paper, plastic film, and sheets.

[Effect of idea]

(a) With the storage case of the present invention, it is possible to store scrolls in the case and easily pull out and cut the film with the lid closed. That is, in the storage case of the present invention, after the previous film cutting, the leading end of the film inside the case is connected to the opening window 7 provided across the case lid and the following folding insertion part, and the opening window 7 provided on the front of the case. opening window 8
Therefore, both sides of the film are exposed to the outside, so you can directly pinch both sides with two fingers and just move your fingertips upward to make the leading edge of the film protrude outside the case. I can,
Cutting can be done by pulling this.

Also, if the scroll rotates at a certain rate inside the case and the leading edge of the film gets stuck inside the case, turn the case upside down from its normal state, i.e., close the lid of the case. If you make sure that the boundary between the front part and the front side is at the bottom, the scroll will be in a position where it touches windows 7 and 8, so insert your index finger through these windows and rotate the scroll until the cutting edge of the film is aligned. can be returned to the location of the opening windows 7 and 8, and their tips can be made to protrude outside the case as described above.

(b) The opening window provided in the case is not formed in advance, so that it can be opened easily at the beginning of use.
By providing perforations with a size and shape corresponding to the opening window, dust and the like can be prevented from flowing into the case during the distribution stage.
