[Field of Industrial Application] The present invention relates to a technique for improving a wrap film storage box that is commonly used in general households, food retailers, and the like.

[0002]

2. Description of the Related Art Conventionally, a front plate 1, a bottom plate 2, as shown in FIG.
A rectangular storage chamber 15 which is formed by the rear plate 3 and the side plate 8 (auxiliary side plate 7) and has an upper opening, and is connected from the side edge of the rear plate 3 of the storage chamber 15 in a direction to cover the storage chamber opening. Cover plate 4
A rectangular box body having a cover lid piece 5 extending from a side edge of the lid board 4 in a direction to cover the front board 1, and requires a winding film R to a wrap film F stored in the storage chamber. A wrap film storage box which is used by pulling out an amount and cutting it with a cutting tool K provided at a predetermined portion of the box along the longitudinal direction of the box is described in, for example, Japanese Utility Model Publication No. 59-28022. Is known.

Most of the boxes of this type are made of paperboard, and are formed by bending the plate surfaces of the respective parts at substantially right angles at the respective folding line portions and extending from the cover plate 4 to the side plate 8. Some have the side cover lid piece 11 or do not have the side cover lid piece 11. The cutting tool is located at the upper end of the front plate 1,
In many cases, the edge of each of the plate surfaces near the ridge between the front plate 1 and the bottom plate 2 and at the tip of the covering lid piece 5 is projected from the plate surface. The overall shape of the cutting tool (the shape of the virtual line connecting the cutting edges) is straight, concave arcuate, convex arcuate, V-shaped projecting, trapezoidal projecting, etc. The types of cutting tools include metal saw blades, plastic saw blades, paper saw blades (including hardened paper), paper saw blades with abrasive grains on the teeth, and paper flat blades with fixed abrasive grains ( It is known that there are no teeth).

Further, as a method of disposing the cutting tool, a box-shaped small piece which is a cutting tool obtained by performing a saw blade process or an abrasive grain fixing process in advance is determined when the box body is a flat board. A method of fixing on the part plate with a caulking tool or an adhesive, or a predetermined part of the paperboard that will be the box body directly directly subjected to saw blade processing or abrasive grain fixing processing, etc. It is also widely known that there is a method of using paperboard as a cutting tool.

In FIG. 4, there is no side cover lid piece 11 extending from the cover plate 4 in the direction to cover the side plate 8, and the shape of an imaginary line connecting the cutting edges is straight on the rear surface of the tip of the cover lid piece 5. 1 illustrates a case where a metal saw blade (cutting tool K) in the shape of a box is a storage box that is fixed and arranged by a caulking tool 12. And FIG. 4 (A)
4B is a diagram of a stage in which the unsealing piece 6 has been removed and then unsealed, and FIG. 4B shows the local joint portion 9 bonding the back surface of the unsealing piece 6 and the front surface of the front plate 1. While cutting line 1
It is a figure of the stage which tried to open and open the opening piece 6 from 0.

In the operation of cutting the film in the storage box shown in FIG. 4, the rear side of the pulled-out film F is sandwiched between the front plate 1 and the covering lid piece 5, and is held in such a manner that the thumb of the covering lid piece is pressed by the thumb of one hand. Then, the leading end of the film F that has been pulled out is held by the other hand in a direction in which the film comes into contact with the cutting edge of the end of the covering lid and bends at an acute angle, and guides the film and the film and the box body to each other in a tensioned state. Generally, the film is contacted with the cutting edge by diagonally turning upside down, and is pressed and cut in such a manner that the film is sequentially bited into the sharp cutting edge from one end to the other end.

[0007]

Recently, the market (consumer) demand placed on this type of storage box tends to become more sophisticated. Among these, the market demand that is difficult to achieve with this type of storage box relates to the cutting performance of the storage box. When trying to start film cutting from one side edge of the film, (a) the side edge of the film converges. Some cut films have wrinkles on the side edges. (B) There is a case where a cut that hits the cutting start portion does not easily enter the end on the side of the film, which makes cutting difficult.
(C) There is a case where a cutting start portion having an angle with respect to the imaginary line of the film width is formed at a position deviated from the planned cutting start portion, and the cutting lines of the film side end portion and the adjacent film are uneven. Alternatively, it is a complaint that it occurs as a phenomenon in which any one of the above-mentioned (a), (b), and (c) defective phenomena occurs together.

According to the research conducted by the present inventors, the above-mentioned defective phenomenon is caused by vertically abutting the film on the entire cutting edge and applying a tension to the leading end of the film so that the film and the box are slanted vertically. When trying to start film cutting from one side edge of the film by turning it oppositely, "When the film at the side edge is slipped over the cutting edge, and only the side edge part and the film in the vicinity Is excessively pulled out in a form that slides on the cutting edge. ”This phenomenon is caused by, for example, a paper flat blade with fixed abrasive grains (without teeth) or paper. Generally, it has a lower ability to break through a film, such as a saw blade, than a metal saw blade, and is more likely to occur in the case of a storage box having a cutting tool whose rigidity / strength of the cutting edge is weak against external force. Holding a metal saw blade made up of mountains In the storage box, the storage box when any particular sharpness of the saw blade side portion by an external force is decreased, leading to the investigation that phenomena described above are those that may occur frequently. The object of the present invention is to include the above-mentioned (a), including concurrent occurrence,
The purpose of the present invention is to provide a storage box with a cutting tool that can avoid the occurrence of the defective phenomena of (b) and (c).

[0009]

SUMMARY OF THE INVENTION The present invention is to achieve the above-mentioned object of the invention.
A rectangular storage chamber 15 formed by the front plate 1, the bottom plate 2, the rear plate 3, and the side plate 8 (auxiliary side plate 7) and having an open upper portion, and the storage chamber 15 from the side edge of the rear plate 3 to the storage chamber. A rectangular box body having a lid plate 4 connected in a direction of covering the opening and a cover lid piece 5 extending from a side edge of the lid plate 4 in a direction of covering the front plate 1, and is stored in the storage chamber. In the storage box of the wrap film, the necessary amount of the wrap film F is drawn out from the wound film R, and the wrap film storage box is used by cutting with a cutting tool K provided along a longitudinal direction of the box at a predetermined portion of the box. The cutting tool K arranged along the longitudinal direction of the box has a size of 1 from the inside of the auxiliary side plate 7 of the storage chamber to the inside of the storage chamber in the longitudinal direction.
One or two or more opening notched concave portions Q at the tip of the cutting tool itself at a position corresponding to a range of up to 20 mm
Is a cutting tool arranged on at least one side of the cutting tool, and is a storage box for a wrap film.

The present invention will be described in detail below. 1, FIG. 2 and FIG. 3 show an embodiment of the present invention, and FIG.
1 is a schematic perspective view illustrating a storage box, and FIG.
FIG. 2 is a schematic plan view showing the structure of the paperboard that serves as the storage box of (A), FIG. 2 is a schematic view showing the position of the opening cutout recess Q in the present invention, and FIG. 3 is the open cutout recess in the present invention. It is a partial schematic diagram which illustrated the shape of Q, and its arrangement.

In FIG. 1A exemplifying the present invention, the storage box has an upper part formed by a front plate 1, a bottom plate 2, a rear plate 3, and a side plate 8 (auxiliary side plate 7). A rectangular storage chamber 15, a lid plate 4 connected from the side edge of the rear plate 3 of the storage chamber 15 in a direction to cover the storage chamber opening, and a side edge of the lid plate 4 extending in a direction to cover the front plate 1. A rectangular box body having the cover lid piece 5 and a necessary amount of the wrap film F is drawn from the winding film R stored in the storage chamber, and is provided along a longitudinal direction of the box body at a predetermined portion of the box body. It is a storage box for a wrap film that is cut by a cutting tool K that has been deployed. Specifically, the armpit cover piece 1 extending from the cover plate 4 in the direction to cover the side plate 8
1 has a flat blade made of paper (without teeth) provided with fixed abrasive grains on the back surface of the tip edge of the lid 5 along the longitudinal direction of the rectangular box. The storage box when the flat blade (without teeth) is the cutting tool K is illustrated.

This storage box can be formed into a box by bending the paperboard mount shown in FIG. 1B along each folding line P. The most remarkable point about this board mount is the folded-back reinforcing plate 1 that is connected to the front plate 1 through a fold line P.
At the tip of 6, as a paperboard cutting tool K arranged via the cut-off line 14, first, at the paperboard stage, for example, cutting edge processing such as fixing abrasive grains to the entire cutting edge of the cutting tool is performed. Then, fold the paperboard along the fold line P between the bottom plate 2 and the rear plate 3,
After performing the operation of laminating the back surface of the above-mentioned paperboard cutting tool K portion on the back surface of the covering lid piece 5 at a position where the cutting edge of the cutting tool K slightly protrudes toward the opening piece 6 side, and then using the cut-off line 14. The paperboard cutting tool K is removed, and then the folded reinforcing plate 16 is attached to the back surface of the front plate 1 by folding back to form a generally known box body. After forming the box, as in the conventional product shown in FIGS. 4 (A) and 4 (B), the local joint portion 9 bonding the back surface of the unsealing piece 6 and the front surface of the front plate 1 is pulled over. When the unsealing piece 6 is removed from the cut line 10 and the unsealing is performed, the box body shown in FIG. 1A is completed. Naturally, this type of box is also used for wrapping a wrap film that is used by pulling out the required amount of the wound film R stored inside and cutting it with a cutting tool K (fixed abrasive grains) provided on the back surface of the leading edge of the cover lid piece. It becomes a storage box. The structure of the storage box with a cutting tool described above is a part common to that of a known storage box.

The cutting tool K of the storage box shown in FIGS. 1A and 1B is illustrated by arranging two opening notched concave portions Q on both sides, but the opening to be placed on the cutting tool is illustrated. There are one notch recess Q on each side, a combination of one and two notches, only one side, and a plurality of notches on each side. That is, the present invention is different from the conventional product in that the cutting tool K arranged along the longitudinal direction of the box has one cutting tool tip edge at the position of the predetermined dimension range of the cutting tool side portion. Or
Two or more opening notched concave portions Q are provided where the cutting tool is arranged on at least one side of the cutting tool.

[0014]

The function of the opening notch concave portion Q is to start the cutting operation, that is, when a tension is applied to the film in order to form a cutting start portion at the end of the film which is in contact with one side of the cutting tool. The role of suppressing "the phenomenon that the side edge film slides over the cutting edge, or only the side edge part or the adjacent film slides over the cutting edge excessively" Even if it acts or is pulled out a little or pulled out a little excessively, the excess film is absorbed by the groove of the opening notched concave portion to form the cutting start portion. This is to fulfill the role of prolonging the chance that the edge portion is in contact with one end of the cutting tool at the end portion.

The contents of the present invention will be described below with reference to the drawings. First, in FIG. 1, the reason why the flat blade made of paper with fixed abrasive grains (without teeth) is illustrated as the cutting tool K in FIG.
The purpose of the present invention is to show the case of a cutting tool having the most remarkable effect of the above, and this cutting tool is conventionally known, for example, a metal saw blade, a plastic saw blade, a paper saw blade, an abrasive grain on the tooth crest. Even if it is replaced with a paper saw blade or the like attached, the same effect can be obtained. In other words, for example, the ability to pierce a film is generally lower than a metal saw blade, such as a paper saw blade with abrasive grains on the teeth and a flat blade with fixed abrasive grains, and the rigidity and strength of the cutting edge against external force In the case of a fragile cutting tool, it is more desirable because the operation effect of the opening notch recess Q is recognized by the evaluation that the initial cutting performance of the cutting tool is improved and the durability of the cutting performance is enhanced. However, on the other hand, even in the case of a cutting tool such as a metal saw blade whose cutting edge itself is made of highly sharp and sharp teeth, resulting in a low possibility of the film sliding on the cutting edge, the above-mentioned opening The action and effect of the cutout recess Q is advantageous in that the action and effect of the open cutout recess Q are exerted beneficially when the sharpness of the tooth crest is slightly lost by repeated use of a cutting tool or some external force.

The opening notch concave portion Q is provided directly on the tip of the cutting tool corresponding to the blade of the cutting tool itself, and may be provided on one side of the longitudinal cutting tool. However, in practice, which side of the box cutting tool is used to start cutting is a matter of discretion of the user's strengths and weaknesses, so it is desirable to place it on both sides of the cutting tool. . Then, the order of forming the blade and forming the notch recess will be appropriately selected depending on the type of the cutting tool to be processed and the convenience of the process, but at least a cutting tool that requires abrasive grain fixation. Then, it is desirable to form the notch concave portion before the abrasive grains are fixed. The reason is that there is a possibility that abrasive grains that adhere when the notch recess is formed may fall off, and it is better to perform resin impregnation hardening treatment or abrasive grain adherence treatment on the periphery of the notch recess as well. This is because the opening notched concave portion Q has a high property and its processing is easy.

FIG. 2 is a cross-section in the longitudinal direction of the box body of FIG. 1 (A), mainly showing the front plate 1, the side plate 8, the auxiliary side plate 7, and the folded back reinforcing plate 16 which form the storage chamber 15. FIG. 6 is a partial cross-sectional view showing the overlapping structure of the paperboards of the covering lid piece 5, the side covering lid piece 11, and the auxiliary side covering lid piece 13 of the lid body that covers it. In FIG. 2, the position of the opening notch concave portion Q to be inserted into the cutting tool is “the position corresponding to the range of 1 to 20 mm in the dimension X measured from the inside of the auxiliary side plate 7 forming the storage chamber to the inside of the longitudinal direction of the storage chamber. The tip of the cutting tool itself ". The reason for this is that the opening notch concave portion Q first exerts its function "0 to 10 mm inside than the side edge of the film pulled out from the box body.
Within the range, it is preferable that the opening notch concave portion Q located at the most side in the longitudinal direction of the cutting tool exists. However, as described in the prior art, the box body has various structures, the number of auxiliary side plates 7 and the like is different, the thickness of the paperboard material is various, and the dimensional variation caused by the bending accuracy is large. Moreover, the position of the side edge of the deployed cutting tool does not always coincide with the side edge of the box. Further, the core ear portions on both sides of the winding film R are
Also, it has a considerable dimensional variation due to the variation of the film width based on the winding tension. Therefore, the position of the side edge of the film that has been pulled out of the box as a whole will fluctuate considerably, and it is difficult to determine from which position in the box it is appropriate to express the positional fluctuation. It's a problem.

In the present invention, the "storage chamber 15
The dimension X measured from the inside of the auxiliary side plate 7 forming the inside to the inside of the longitudinal direction of the storage chamber is defined as the prescribed dimension, and the position where the opening notch concave portion Q exists is cut at a position corresponding to the range of 1 to 20 mm. It was intended to deal with this by defining it as "the tip of the tool itself". That is, if the existing position is less than 1 mm in dimension X, the meaning of existence of the opening notched concave portion Q is poor, and conversely, if the existing position exceeds 20 mm in dimension X, the opening notched concave portion Q may catch the side edge of the film inside. Means poor. Therefore, the opening notch concave portions Q for surely capturing the side edge of the film are generally two in the position of the dimension X in the range of 1 to 20 mm and with the groove center-to-center distance of 2 to 6 mm. Or, it is desirable to arrange three opening notch concave portions Q. However, arranging more than four opening notched concave portions Q in some cases may induce a reduction in local sharpness of the cutting tool itself, and thus it is preferable to avoid it.

As shown in FIGS. 3 (A), (B), (C), and (D), the shape of the opening notch recess Q is V-shaped or U-shaped in the shape of the groove in which the cutting edge K'is opened. The cutout recess has an opening size of 1 to 5 mm (desirably 1.5 to 3 mm) and a groove depth of 1.5 to 5 mm (desirably 2 to 3 mm). A point different from the tooth crest (root) of a normal saw blade is that the front ends of both sides of the opening are formed flat. Therefore, even when the saw blade cutting tool having the tooth crests provided with the opening notch recess Q having a V-shaped groove, the opening notch recess Q is not confused with the trough forming the tooth crest.

The paperboard used in the present invention has a thickness of 0.35.
About 1.5 mm thick paper, generally thicker
A strong and strong box can be obtained, but bending is difficult, so the thickness is usually 0.35 to 0.8 mm (weighing 3
The relatively thin paperboard in the range of 10 to 550 g / m ² ) is used.

[0021]

[Example] Meat thickness of about 0.5 mm (weighing 400 g / m ² ).
Using the cardboard of No. 2 as a base material, a paperboard mount for a storage box shown in FIG. 1 (B) was prepared. The cutting tool K for the mount is 2 mm from the side edge of the mount on each side of the leading edge of the mount part to be the cutting tool.
And the groove size is V-shaped at the position of 6 mm and the opening size is 2 m
m, the groove depth is 2 mm, and two opening notched concave portions Q are formed in advance, and the width is about 3 from the tip side edge of the mount portion to be the cutting tool.
An ultraviolet curable adhesive (# EC-12-0, made by Cashew Co., Ltd.) is applied to the part of mm along the longitudinal direction, and a three-step processing of a base curing treatment, an abrasive solidification treatment and an overcoat treatment. After the treatment, a cutting tool processing was performed in which abrasive grains (alumina grains of No. 46 according to JIS R8001) were fixed to the front side edge of the mount.

In this case, as a method of curing the adhesive, a method of vertically irradiating a 400 W ultraviolet lamp (trade name: Cuarab DX, HLD-400D, manufactured by Sen Special Light Source Co., Ltd.) from above 15 cm was adopted. . At the time of forming the box body, first, the paperboard is bent along the fold line P between the bottom plate 2 and the rear plate 3, and the back surface of the paperboard cutting tool K part is cut by the cutting tool K.
The cutting edge (abrasive grain fixing part) of the above hits the position slightly protruding to the side of the opening piece 6 and then the operation is performed such that the cutting edge K is overlapped on the back surface of the covering lid piece 5, and then the paperboard cutting tool K is detached by the cut line 14. Then, a commonly known box body was formed, and a vinylidene chloride resin film (trade name: Saran Wrap, manufactured by Asahi Kasei Co., Ltd.) wound around the box body was stored. Similar to the conventional product, this box body is formed by pulling out the local joint portion 9 bonding the back surface of the unsealing piece 6 and the front surface of the front plate 1 and removing the unsealing piece 6 from the cut line 10 to open the box. The box body shown in FIG. 500 boxes of this box were prepared, and for comparison, the same number of boxes differing from those of the above-mentioned example only in that the opening notched concave portion Q did not exist was prepared, and the following comparative evaluation was performed.

(Evaluation method) (a) Ease of cutting start First, the film F that has been pulled out is sandwiched between the front plate 1 and the lid lid piece 5, and the central portion of the lid lid piece 5 is held by the thumb with one hand. Then, the film is brought into contact with the cutting edge of the tip of the covering lid piece 5 and bent by about 100 degrees to be inverted.

Hold the leading end of the film F pulled out on one hand in the other hand and guide it, and in that state, fix the box body by tilting it downward toward the horizontal pedestal at an angle of 30 degrees with respect to the horizontal pedestal. The jig is fixed to the jig and the central portion of the leading edge of the film is fixed to the chuck. The chuck is pulled in a lateral direction parallel to the pedestal so as to apply tension to the film, and the cutting is started from one side end of the film which is in contact with the lower end cutting edge of the cutting tool. The tension required to start the cutting is measured by a spring meter connected to the tip of the chuck. It can be said that the lower the tension value is and the less the tension is, the easier it is to start cutting.

(B) Sustainability of the ease of starting the cutting For the storage box after the film has been cut 100 times by the method of the above (a), the same tension required for starting the cutting as in the above (a) is measured. This tension value is higher than the value of (a),
In addition, it can be said that a storage box (cutting tool) having a small variation that has a long easiness of starting cutting is provided.

(C) Wrinkle occurrence rate on the film side end The film at the time of cutting in the 100 times / one box cutting test carried out in the above (B) was observed for each box, and "the film side end was pulled. The occurrence rate of "wrinkles caused by gathering" was obtained.
In this evaluation, the wrinkles that occur concurrently in the "film film irregularity phenomenon" evaluated in (d) below are added to this occurrence rate.

(D) Occurrence rate of film line non-uniformity phenomenon The film at the time of cutting in the 100 times / one box cutting test carried out in (b) above for each box was observed, and "film side edge" The occurrence rate of the film cut line misalignment phenomenon was determined by "the part is pulled up by hand" or "the film side edge part and its neighboring film are excessively pulled out". In this evaluation, if the wrinkles evaluated in the above (c) and the "film film irregularity phenomenon" occur together, the occurrence rate is also added.

A summary of the evaluation results of the storage boxes of the above Examples and Comparative Examples is shown below. Examples Comparative Example Ease of starting cutting Average value 120 g 200 g Fluctuation range ± 80 g ± 150 g Sustainability of easiness of starting cutting Average value 150 g 500 g Fluctuation range ± 100 g ± 250 g Wrinkle occurrence rate on film side edge 1/100 times 12 Times / 100 times Incidence of film cutting line misalignment 3 times / 100 times 20 times / 100 times

[0029]

EFFECTS OF THE INVENTION The storage box of the present invention has the above-mentioned structure, so that when the film is cut, a wrinkle is generated at the end portion on the film side, and the cutting line on the film side end portion and in the vicinity thereof is not formed. This has the effect of significantly suppressing the occurrence of the phenomenon of becoming uniform. Moreover, when the present invention is applied to a cutting tool that uses, for example, the corners of fixed abrasive grains as a cutting edge, in addition to the above effects, the sharpness at the start of cutting is enhanced, and the advantage that the sharpness lasts is extremely high. It is effective. Therefore, the present invention is an excellent invention that is beneficial to the industrial world.
