BACKGROUND OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wound sheet cutting storage box, and more particularly to a wound sheet cutting storage box that pulls out a stored wound sheet such as an aluminum foil and cuts the wound sheet into a desired length.
[0002]
[Prior art]
FIG. 9 is a perspective view showing the appearance of a conventional wound sheet cutting storage box.
Referring to the drawing, a conventional sheet cutting box 51 has a rectangular parallelepiped box shape in which a wound sheet 23 wound around a core 24 is stored. A rectangular opening 52 is formed in the openable / closable opening / closing lid 16 that covers the upper side of the sheet cutting box 51, and a band-shaped cutting blade 25 is attached to one side of the sheet cutting box 51.
[0003]
Next, a method of using the sheet cutting box 51 will be described.
First, the wound sheet 23 is stored in the sheet cutting box 51 with the opening / closing lid 16 opened. In this state, the winding core 24 is supported at both ends by components not shown, and the winding sheet 23 is rotatable. Then, the foil sheet 34 is pulled out from the end portion of the wound sheet 23, and the opening / closing lid 16 is closed in a state where the foil sheet 34 is inserted through the opening 52 outward. Next, the foil sheet 34 is cut by the cutting blade 25 by pulling out the drawn foil sheet 34 so as to straddle the cutting blade 25 and pushing it downward.
[0004]
In this way, the foil sheet 34 is pulled out from the wound sheet 23 one after another through the opening 52 and is used by being cut by the cutting blade 25 at a desired position.
[0005]
[Problems to be solved by the invention]
In the conventional sheet cutting box as described above, when the sheet is cut, the opening / closing lid 16 does not need to be opened one by one and can be continuously pulled out and cut, so that the short pieces of aluminum foil are used one after another. For example, it is convenient for use in a beauty salon.
[0006]
However, in the case of a conventional sheet cutting box, the sheet on the side of the wound sheet remaining after cutting may be rewound in some cases. Depending on the degree, the opening 52 may be reversed and all the drawn sheets may return to the inside of the sheet cutting box. Therefore, in the next use, it is necessary to open the opening / closing lid 16, draw the sheet again from the wound sheet 23, insert the opening 52, and pull it outward. For this reason, it is not always easy to use when continuously drawing and cutting the sheet.
[0007]
FIG. 10 is a diagram for explaining the sheet rewinding phenomenon, and is a plan view of the sheet cutting box 51 in FIG.
Referring to the figure, the length in the lateral direction of the opening 52, that is, the distance L between the end edges 53a and 53b is larger than the length W in the width direction of the foil sheet 34 in order to smoothly pull out the foil sheet 34 from the opening 52. It is set large. Therefore, after the foil sheet 34 is cut, when the remaining sheet is not pressed, when the rewinding force of the sheet is generated due to the rotational balance of the wound sheet 23, the remaining sheet has no resistance at all. It will return to the inside of the box 51 for cutting.
[0008]
The present invention has been made to solve the above-described problems, and is for cutting a wound sheet that prevents rewinding without pressing the remaining sheet by hand even after the drawn sheet is cut. An object is to provide a storage box.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the invention according to claim 1 stores a wound sheet obtained by winding a belt-shaped sheet, and cuts the sheet drawn from the wound sheet in an arbitrary position in the width direction. A storage box for cutting a wound sheet for attaching a box body for storing a wound sheet, a lid for closing the top of the box body, and an edge of the lid so as to protrude upward from the upper surface of the lid The width of the front edge near the cutting blade is larger than the length in the width direction of the sheet, and the width of the rear edge far from the cutting blade is in the width direction of the sheet. And an opening having a shape of a length or less.
[0010]
If comprised in this way, when the sheet | seat by the side of the wound sheet | seat after cut | disconnecting will retreat, both the side edges of a sheet will contact each of the side edge part which connects the front edge and rear edge part of opening.
According to a second aspect of the present invention, in the configuration of the first aspect of the invention, the box has a rectangular parallelepiped shape, and the lid is formed integrally with the box so that the upper side of the box can be opened and closed. The opening has a trapezoidal shape having a bottom side parallel to the mounting direction of the cutting blade, and the upper side of the trapezoidal shape is located at the upper end of the box.
[0011]
If comprised in this way, a sheet | seat will contact in each of the side of a trapezoid-shaped opening, and the rewinding will be blocked | prevented.
According to a third aspect of the present invention, in the configuration of the second aspect of the present invention, the flap further includes a flap that is foldable and integrally formed in the box so as to close the opening, and has a trapezoidal shape substantially the same as the opening. It is a thing.
[0012]
If comprised in this way, it will become possible to block | close an opening with a flap. Further, an opening and a flap are formed by cutting a portion corresponding to the side excluding the upper side of the trapezoidal shape of the opening with respect to the lid in which the opening is not formed.
According to a fourth aspect of the invention, in the configuration of the third aspect of the invention, the flap is configured such that the bottom side portion can be bent with respect to the upper side portion at a position parallel to the bottom side.

Fold the flap. Then, the flap always presses the outer surface of the wound sheet by the repulsive force of the bending of the flap. Therefore, even if the outer diameter of the wound sheet is reduced, the unwinding of the drawn sheet is prevented.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a perspective view showing the appearance of a sheet cutting box as a wound sheet cutting storage box according to the first embodiment of the present invention.
Referring to the drawing, a paper sheet cutting box 14 is a rectangular parallelepiped box 15, an opening / closing lid 16 that is integrally formed with the box 15, and that allows the upper part of the box 15 to be opened and closed, and the box. For example, a cutting blade 25 made of synthetic resin is provided at the upper end of the 15 front walls 21. In addition, in the sheet cutting box 14 before use, it is not preferable in terms of safety if the cutting blade 25 is exposed to the outside. Therefore, the bent piece 20 of the opening / closing lid 16 is formed so as to cover the box. It is in a state of being inserted into insertion slits 22 a and 22 b formed on both sides of the front wall 21 of the body 15.
[0018]
Further, a linear slit 17 is formed on the upper surface of the opening / closing lid 16 in parallel with the mounting direction of the cutting blade 25, and the perforations 18a, Each of 18b is formed. Perforations 26a and 26b are formed from the middle of each of the perforations 18a and 18b toward the slit 17. These perforations are provided so that they can be easily cut from the portion without using scissors or the like in use. The reason why the slit 17 has been cut before use is to keep the sectional surface smooth and not to damage the foil sheet that is in contact therewith during use. A ruled line 19 that connects the intersections of the perforations 18a and 18b and the perforations 26a and 26b is formed, and this is provided so that both sides of the ruled line 19 can be bent. It is.
[0019]
Further, inside the sheet cutting box 14 is accommodated a cylindrical wound sheet 23 in which a sheet such as a belt-shaped aluminum foil is wound around a core 24. Note that both ends of the winding core 24 are held by holding plates (not shown in the figure), and the winding sheet 23 is housed in a rotatable state together with the winding core 24.
FIG. 2 is a plan view showing a state in which the bent piece 20 of the opening / closing lid 16 is extracted upward from the insertion slits 22a and 22b of the front wall 21 and the bent piece 20 is inserted inside the cutting blade 25 from the state of FIG. FIG. Thereby, the cutting blade 25 is exposed in a manner protruding from the upper surface of the end portion of the opening / closing lid 16. Thus, the cutting blade 25 is in a state where the drawn sheet can be cut.
[0020]
Further, as described above, the core holding plates 27a and 27b for rotatably holding the core 24 are accommodated in the box 15, and the core holding plates 27a and 27b are shafts of the winding sheet 23. The movement in the direction is limited to assist the sheet being pulled out in a stable rotating state. When this sheet cutting box is used, the perforations 18a and 18b formed on the surface of the open / close lid 16 are used to cut the slits 17 at this portion to make the inner portion a flap 31. Note that if the flap 31 is further cut at the perforations 26a and 26b to remove the hatched portions, the usability is improved as will be described later.
[0021]
FIG. 3 is a perspective view showing a usage state of the wound sheet cutting storage box according to the first embodiment of the present invention.
Referring to the figure, in use, the opening / closing lid 16 is opened upward, a part of the sheet is pulled out from the wound sheet 23, and the drawn sheet is passed through the opening 35 formed simultaneously by forming the flap 31. The opening / closing lid 16 is closed in this state. If the flap 31 is in a state where the bent portion 33 is slightly raised upward with respect to the flat portion 32 with the ruled line 19 as a boundary, the exposed portion of the opening 35 becomes larger, and the foil sheet 34 can be pulled out more smoothly. .
[0022]
When the drawn foil sheet 34 is cut, the foil sheet 34 is further pulled out so as to straddle the cutting blade 25, and the portion pulled out at a desired position is pressed down against the cutting blade 25. . The foil sheet 34 pulled out by this is cut in the width direction by the cutting blade 25. Next, when cutting a new sheet, the foil sheet 34 remaining after cutting may be further pulled out and cut at a predetermined position by the cutting blade 25 by the same operation.
[0023]
By the way, in the case of the conventional sheet cutting box, the foil sheet 34 left after the cutting may be rewound into the box 15, but in the sheet cutting box 14 according to this embodiment, There is no fear.
FIG. 4 is a plan view of FIG. 3 for explaining such a rewinding prevention function, and FIG. 5 is a cross-sectional view taken along the line VV of FIG.
[0024]
Referring to these drawings, the opening 35 formed in the opening / closing lid 16 has a substantially trapezoidal shape whose bottom is parallel to the installation direction of the cutting blade 25 and whose upper side is located on the upper edge side of the opening / closing lid 16. ing. The length L ₁ of the front edge portion 28 corresponding to the lower side of the trapezoidal shape of the opening 35 is larger than the length W in the width direction of the foil sheet 34, and the length of the rear edge portion 29 corresponding to the upper side of the opening 35 is set. The length L ₂ is set smaller than the length W in the width direction of the foil sheet 34. The distance between the edges P ₁ and P ₂ of the side edges 36 a and 36 b connecting the front edge 28 and the rear edge 29 of the opening 35 coincides with the width W of the wheel seat 34.
[0025]
As shown in FIG. 5, the foil sheet 34 drawn out from the wound sheet 23 is pulled by a pulling force before being cut by the cutting blade 25. In this state, the front edge 28 of 35 is slid. The length L ₁ of the leading edge 28 because it is set larger than the width W of the foil sheet 34 as described above, withdrawal of the foil sheet 34 is carried out smoothly.
[0026]
Next, when the pulled-out foil sheet 34 is cut by the cutting blade 25, the remaining foil sheet 34 is not pulled by the pulling force, so that its front end is lifted as shown by the two-dot chain line. Change. However, side edges 36a of the openings 35, 36b is to the point P _1, P ₂ as a boundary, a rear end, i.e. in terms of the FIG. 5, the width of the opening 35 toward the left direction of the wheel seat 34 width It is narrowed to become W or less. Therefore, the foil sheet 34 raised after cutting does not lift above the positions of the points P ₁ and P ₂ whose widths coincide. That is, the foil sheet 34 left after cutting is prevented from moving by contacting the side edge portions 36a and 36b at the points P ₁ and P ₂ , and as a result, the unwinding operation of the wheel seat 34 after cutting. Is blocked. Since the relationship between the width W of the foil sheet 34 and the shape of the opening 35 does not change in use, the foil sheet is always drawn even when the operation of continuously pulling out and cutting the foil sheet 34 is repeated. Thus, the rewinding operation of 34 is prevented.
[0027]
FIG. 6 is a cross-sectional view corresponding to FIG. 5 and showing another example of the usage state.
In FIG. 5, the flap 31 is used without applying any particular force, but in FIG. 6, a state in which force is applied to the flat portion 32 of the flap 31 in the direction indicated by the arrow is shown. . After the drawn foil sheet 34 is cut by the cutting blade 25, when a force is applied to the flat portion 32 as shown in the figure, the tip of the foil sheet 34 left after being cut by this pressing is further moved upward as indicated by an arrow. Lift up. For this reason, compared with the state shown in FIG. 5, the foil sheet 34 is positioned higher and away from the cutting blade 25, so that the tip of the foil sheet 34 can be more easily grasped. As a result, the continuous withdrawal of the foil sheet 34 can be performed safely and smoothly.
[0028]
FIG. 7 is a view corresponding to FIG. 4 and showing still another example of use of the flap 31.
Referring to the figure, the bent portion 33 of the flap 31 is folded back so as to overlap the flat portion 32. Thus, both end portions of the bent portion 33 are always in contact with the upper surface of the opening / closing lid 16. For this reason, in the usage example of FIG. 4, when the flap 31 is pressed with a finger, the flap 31 moves downward from the opening 35, and the flap 31 comes into contact with the wound sheet 23 to pull out the wheel 34. There was a risk of giving resistance. However, when used as shown in FIG. 7, even when the finger is placed on the bent portion 33, the flap 31 does not move below the opening 35 and can be used stably. .
[0029]
FIG. 8 is a diagram corresponding to FIGS. 5 and 6 and showing another example of use of the flap 31.
When many foil sheets 34 are pulled out from the wound sheet 23 and used, the outer diameter of the wound sheet 23 becomes smaller than that at the initial drawing. In this case, compared to the initial state shown in FIG. 5, the upward lifting of the foil sheet 34 that remains after being cut is reduced, so that the foil sheet 34 contacts the points P ₁ and P _{2 of the} opening 35. The force is reduced, and the function of preventing the roll sheet 34 from rewinding is lowered. In this case, the bent portion 33 of the flap 31 is bent downward with respect to the flat portion 32, and further bent downward at a connection portion with the back wall 41 of the flat portion 32. In this way, the flap 31 is pushed between the inner surface of the back wall 41 of the box 15 and the outer surface of the wound sheet 23. In this case, if the hatched portion is removed from the flap 31 as shown in FIG. 2, the flap 31 does not come into contact with the core holding plates 27a and 27b when pushed, which is convenient.
[0030]
When the flap 31 is thus installed, the outer surface of the wound sheet 23 is always pressed by the flap 31 due to the bending of the flat portion 32 and the bent portion 33. Therefore, the foil sheet 34 drawn out from the wound sheet 23 is not easily rewound even after being cut by the cutting blade 25, and the continuous drawn state is maintained smoothly. Further, when the flap 31 is folded into the box 15 in this way, the opening 35 is exposed entirely. Therefore, even if the cut foil sheet 34 is rewound and stored in the box 15, the foil sheet 34 can be easily pulled out through the opening without opening the opening / closing lid 16 again. Become. In this manner, the wheel seat can be smoothly pulled out from the stored wound sheet without opening the opening / closing lid 16 from the beginning to the end, and can be cut and used at any position.
[0031]
In addition, the concept of the trapezoidal shape as the opening of the present invention is not only a geometric trapezoidal shape but also a shape in which the side edge is bent instead of a straight line as shown in the above embodiment, A shape in which the side edge portion is not a straight line but a curved line is also included.
In the above embodiment, the opening of the lid is formed together with the formation of the flap. However, the flap is not necessarily required, and only the opening may be formed in the lid as long as it has the same opening shape.
[0032]
Furthermore, in the above embodiment, the opening is formed in the opening / closing lid, but it may be formed in a surface other than the opening / closing lid.
Furthermore, in the above embodiment, the aluminum foil is targeted as the wound sheet, but the present invention can be similarly applied to other sheets such as a transparent film sheet.
