DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for improving a wrap film storage box, which is widely used in households and food retailers.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
A rectangular storage room 13 formed by the rear plate 3 and the side plate 8 and having an open upper portion; a lid plate 4 connected to a direction from the side edge of the rear plate 3 of the storage room 13 to cover the storage room opening; It is a rectangular box having a cover piece 5 extending in a direction covering the front plate 1 from a side edge of the cover plate 4. A wrap film storage box cut and used by a cutting tool K provided at a predetermined portion of the box along the longitudinal direction of the box is used, for example, as described in Japanese Utility Model Laid-Open No. 59-28022 . is there. Most of this type of box is made of paperboard, and is formed by bending the plate surface of each part at substantially a right angle at each fold line portion, and a side cover part extending from the cover plate 4 in a direction to cover the side plate 8. 11
There is also a case where the side cover piece 11 is not provided. The cutting tool K is disposed at the upper end of the front plate 1, near the ridge between the front plate 1 and the bottom plate 2, or at the position where the blade edge of any of the plate surfaces at the tip of the cover piece 5 projects from the plate surface. There are many things. In addition, the overall shape of the cutting tool (shape of the imaginary line connecting the cutting edges) is straight, concave arc, convex arc, V-shaped, trapezoidal, and the like. The types of cutting tools include metal saw blades, plastic saw blades, paper (including vulcanized hardened paper) saw blades, paper saw blades with teeth attached to abrasive grains, and paper flat blades with fixed abrasive grains. (Without tooth ridges) are known.

[0003] Further, as a method of disposing a cutting tool, a band-shaped small piece, which is a cutting tool obtained by previously performing saw blade processing, abrasive grain fixing processing, or the like, is placed at a predetermined stage when the box body is flat paperboard. A method of fixing with a caulking tool or adhesive, etc. on the part board, or a predetermined part of the paperboard to be the box body, directly applying 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.

[0004] Figure 3, which does not have the side Engai piece 11 was cast in a direction to cover the side plates 8 from the lid plate 4 within the storage box, a metal cutting tool K at the distal end rear side of Engai piece 5 FIG. 3B shows a storage box when the storage box is fixed by the swaging tool 12.
The opening piece 6 from the storage box, the steps to be opened by cutting is removed by tear-off line 10 while advancing the peeling of a portion of the local joint 9, FIG. 3 (A) step of pulling out the film F is opened FIG.

[0005] Further, as a storage box in which a temporary fixing portion Q of a film is arranged on a front plate 1 covered with a cover piece 5, for example, Japanese Utility Model Laid-Open No. 54-80430 discloses a storage box such as a resin film layer or a metal foil layer. In Japanese Utility Model Laid-Open Publication No. 57-49430, it is stated that a smooth long member is disposed in the longitudinal direction of the box on the upper surface of the front plate 1. It is disclosed in Japanese Patent Application Laid-Open No. 1-91 that a central part is arranged at one place.
Japanese Patent Publication No. 51 proposes that a crosslinkable hardening varnish is applied to the temporary fixing portion so as to have a smooth surface.

[0006] Any of the temporary fixing portions Q of the film has a phenomenon in which the cut end of the drawn-out film rewinds into the box due to the momentum at the time of cutting (the next drawing-out becomes difficult). This function has a function of locking (preventing rewinding) in a proper state. Conventionally, each company has always increased the locking force of the temporary fixing portion, and arranged a temporary fixing portion having a relatively small area such as a circle or a square at the center in the longitudinal direction of the box.

[0007]

However, in the conventional storage box described above, the temporary fixing (locking) portion lacks the locking force as viewed from the entire film width, and the temporary storage (locking) portion has an impact when cutting or lifting the lid. rewinding is contrary prone the film, in the local the film is engaged it is not easy too adhesion force firmly take strip the film edge during the next withdrawn from the locking portion, withdrawal of the film operability problems worsen, and when peeling picking operation so as to induce longitudinal split phenomenon of the film the treatment flame Wataru problems, or there is a problem such as damage the finger tip of the cutting tool.

On the other hand, when cutting out the drawn-out film from the side end thereof, the designed cutting performance of the cutting tool side end, which is the starting point of the cutting, is lowered due to the side slip of the film, and the side of the cut film is cut off. There is also a problem that the shape of the end portion is not linear, but is irregular and difficult to see. This kind of failure phenomenon is remarkable in a storage box in which a cutting tool is provided at the tip of the cover piece.

SUMMARY OF THE INVENTION It is an object of the present invention to enhance the film locking ability at the temporary fixing portion, facilitate the peeling of the film, prevent the longitudinal tearing of the film at the time of the peeling operation and the problem of scratching the finger. An object of the present invention is to provide a film storage box in which the cutting performance of a cutting tool serving as a starting point of cutting is prevented from deteriorating, and an improved shape is provided so that the cut side edges of the film are aligned in a straight line.

[0010]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object. That is, the present invention provides a rectangular storage room 13 having an open top formed by the front plate 1, the bottom plate 2, the rear plate 3, and the side plate 8, and storing the storage room 13 from the side edge of the rear plate 3. Lid plate 4 connected in the direction covering the chamber opening
And a cover piece 5 extending from the side edge of the cover plate 4 in a direction to cover the front plate 1, and a temporary fixing portion Q for locking the cut film on the surface of the front plate 1 covered with the cover piece 5. A rectangular box body having a required amount of the wrap film F drawn from the rolled film R stored in the storage chamber 13 and cut with a cutting tool K provided at the tip of the cover piece 5 to be used. In the storage box, the temporary fixing portion Q is located at a lower position from a position 3-6 mm away from an upper end edge of the front plate 1 to a position just before reaching a cutting edge of the cutting tool K at the tip of the cover piece 5, and has a longitudinal shape of the box body. At least on both sides in the longitudinal direction of the cover piece 5, at least on both sides in the longitudinal direction of the cover piece 5, a concave processed portion E protruding toward the front plate 1 on the back surface of the paperboard at a position overlapping the temporary fixing portion Q. Is provided in a wrap film storage box, That.

Hereinafter, the present invention will be described in detail. 1A and 1B show an embodiment of the present invention. FIG. 1A is a schematic perspective view illustrating a storage box, and FIG. 1B is a schematic plan view of a mount used as the storage box in FIG. It is. FIG. 1 illustrates the present invention.
2A, the storage box itself includes a rectangular storage room 13 having an open top formed by a front plate 1, a bottom plate 2, a rear plate 3, and a side plate 8, and a rear plate 3 of the storage room 13. A rectangular box having a cover plate 4 connected in a direction to cover the opening of the storage chamber from the side edge of the cover plate 4 and a cover piece 5 extending in a direction to cover the front plate 1 from the side edge of the cover plate 4 This is a wrap film storage box which is used by extracting a required amount of the wrap film F from the rolled film R stored in the chamber 13 and cutting the wrap film F with a cutting tool K provided at the tip of the cover piece 5.

However, the box shown in FIG.
Similarly to the conventional product shown in FIG.
The surface is shown as a box in a state where the local bonding portion 9 that is pasted to the surface of FIG. More specifically, it has a side cover piece 11 extending from the cover plate 4 in a direction to cover the side plate 8, and a cutting tool K is provided on the back side of the front edge of the cover piece 5 along the longitudinal direction of the rectangular box.
As an example, a storage box in which a metal saw blade is fixed with a swaging tool 12 is shown. The structure of the storage box with the cutting tool described above is a common part with a known storage box, and thus can be appropriately replaced with, for example, the known one described in the section of the prior art.

A method of cutting the film F drawn out of this type of storage box is such that a film connected to the rolled film R is sandwiched between the front plate 1 and the cover piece 5, and a substantially central portion of the cover piece 5 is formed. Hold it with your thumb to fix it, pull it out with the cutting edge of the cutting tool K at the tip of the cover piece at a sharp angle of approximately 45 degrees or less between the films, guide the film on the end side upward, and further film While applying tension to the box, the box or the film is guided obliquely in the direction in which the cutting edge at one side end of the cutting tool cuts through the film that comes in contact with it. In this operation, the film is generally cut along the cutting edge from the side of the film contacting the cutting edge at one side end of the cutting tool toward the other side end. Then, the remaining film sandwiched between the front plate 1 and the cover piece 5 will be the next drawing end.

The point that the present invention is different from the conventional product is as follows.
(1) The temporary fastening portion Q is located on the lower side just before reaching the cutting edge of the cutting tool K at the tip of the cover piece 5 from a position 3-6 mm away from the upper edge of the front plate, and extends the entire length of the box body. (2) At least on both sides in the longitudinal direction of the cover piece 5, projecting toward the front plate 1 side at least on the back surface of the paperboard at a position overlapping (opposing) the temporary fastening portion Q. That is, there is provided a concave surface processed portion E which has been subjected to concave surface processing.

[0015]

The role of the above-mentioned construction of the present invention is that any one of the temporary fixing portions Q arranged in a strip shape over the entire longitudinal length of the front plate 1 at the time of cutting the film exhibits an effect of locking the film (preventing rewinding). As a result, the film locking effect is reliably exerted on both longitudinal sides of the cover piece 5 provided with the concave processing portion E. As a result, the accuracy of the effect of preventing the film from being rewound is increased and the cover piece is parallelized. Degree, levelness is maintained,
Versus the design performance of the cutting performance of the cutting tool side end as a cutting start point
This has the effect of suppressing the lowering phenomenon that occurs and making the shape of the side end portions of the cut film straight. The space between the cutting edge of the tip of the cover piece and the temporary fixing portion Q stopped short of the cutting edge exerts an effect of facilitating the picking of the film when the film is peeled. Thus a result, the effect of reliable unwinding prevention and the ease effects of stripping picking the film from the box body, will be implemented by both.

[0016] In general, the storage box of wrap film even if limited to the box body of this kind, interest-out hand or right or left, the direction of the hand to use mainly, operation ways of dealing with the box body at the time of cutting, put in a box Consumers have the advantage in terms of finger position, picking position at the time of stripping, stripping order, and the like. In addition, since this type of box is a rectangle whose length in the longitudinal direction is extremely large (the larger the film width) compared to the other two dimensions, the longitudinal portion, particularly the cut portion, is used.
It is difficult to secure the parallelism and horizontality of the tip of the cover piece to which the cutting tool is fixed, and as a result, the shape of the cutting tool viewed from the blade edge direction is bent in a convex shape at the center and the cutting edge of the cutting tool Is inclined in a direction away from the front plate surface in many cases. The storage box with the cutting tool deformed in this way does not exhibit the original cutting performance of the cutting tool because the cutting edge does not easily come into contact with the film perpendicularly, and is easily affected by the convenience of the consumer.
Therefore, the above configuration is more reliable than the conventional level in any use in studying the relationship between the position and movement of the film with respect to the front plate when all of these uses are made. The position and shape of the temporary fastening portion Q that exhibits the function effect of preventing unwinding, yet allows easy peeling (take-out) of the film, and can secure the cutting ability of the cutting tool and the drawability of the film from the box. And the relationship with concave surface processing applied to paperboard.

In the present invention, the shape of the band of the temporary fastening portion Q is as follows.
In general, it may be a simple rectangular shape having a fixed width in a size range of 6 to 35 mm, or a band shape or a wavy band shape having a partially different width size. Among them, a belt-like body having a partially different width dimension is desirable. FIG. 2 is a schematic plan view of a front plate showing a desirable shape and a position of a temporary fixing portion Q in the present invention. FIG. 2A shows a basic concept, and FIG. FIG. 2C shows a specific embodiment thereof.
Hereinafter, the role of the temporary fastening portion of the present invention will be described with reference to FIG.

First, referring to FIG. 2A, the temporary fastening portion Q according to the present invention will be described.
The cover piece 5 extends downward from the upper edge of the front plate 1 on the front plate 1 surface.
3 to 6 mm (corresponding to X1) from the upper edge of the front plate 1 at the dimensional position (corresponding to X) before reaching the cutting edge of the cutting tool K at the tip of
Cover piece 5 from the upper side to the lower side of the front plate 1 (away)
At a position just before the cutting edge of the cutting tool K at the distal end, the cutting tool K is arranged as a band extending over the entire length of the box.

The necessity of this position plays a role in increasing the accuracy of the contact of the film F with the temporary fixing portion Q when the cover piece 5 is pressed with a finger at the time of cutting. That is, no matter which position of the cover piece 5 is pressed, the film comes into contact with the temporary fixing portion Q extending in the longitudinal direction to increase the accuracy of the contact. And X1 = 3 ~ from the upper edge of the front plate 1
The necessity to leave (separate) 6 mm is to prevent the film from being pulled out of the box body due to the provision of the temporary fixing portion Q, and to prevent the film from slipping at the time of cutting, thereby making it possible to cut the cutting tool. It is for maintaining the cutting performance. In this case, the band-like width of the temporary fixing portion Q is stopped even before the cutting edge of the cutting tool K at the tip of the cover piece 5 even in a wide (projection) portion. That is, it stops by the position located 2 to 6 mm inside from the cutting edge. This function prevents longitudinal tearing of the remaining film end when the film is peeled.

The widths Y1 and Y2 of the temporary fixing portion Q and the width of the notch (Y2-Y1) are the width (corresponding to X) up to the blade edge of the cover piece of the box to be used, and the box body. It is determined by the size of the whole (depending on the relationship between the film width and the winding amount). Generally, Y1 is 5 to 15 mm, Y2 is 15 to 30 m
m and (Y2-Y1) are selected from the range of 5 to 15 mm. At this time, when the width of Y2 is the width of the band, the width dimension (Y2-Y1) of the cutout portion is selected in a range where the width of Y1 is half to one-fourth the width of Y2. become.

The length Z of the notch located at the longitudinal center
1 is 50 to 160 mm, and the lengths Z2 and Z3 of the cutouts located at both ends are selected from the range of 10 to 90 mm according to the longitudinal dimension of the target box (depending on the film width). The lengths L1 and L2 of the projections are 25 to
It will be selected in the range of 120 mm. Z1 at this time
~ Z3 may be the same length dimension or may be different dimensions, but it is better to take Z1 in the center as long as 80-150mm and make Z2 and Z3 shorter than Z1 Desirable because stripping is easy.

In short, the portions Z1 to Z3 are portions for facilitating peeling (extracting) of the film, and the entire band including the projections corresponds to a portion for exhibiting a reliable effect of preventing unwinding. The harmony of both is achieved by the size of the shape area of both. In other words, the portion of the temporary fixing portion Q that reaches the end of the box while being narrowed by the cutouts at both ends prevents the film end from skidding at the start of cutting, and reduces the cutting ability of the cutting tool due to skidding. To prevent
The portion cut off by the notch is an area that controls the starting point and the ease of stripping of the film from the locking portion, and the top portion is formed with the top portion facing the bottom plate side of the box. The strip having the mountain protrusions plays a role of locking the film at any position of the cover piece even when the cutting operation is pressed. Therefore, the temporary fastening portion Q of the present invention
Means that the film width dimension to be stored is, for example, 15c
In the case of m, 22 cm, 30 cm, and 45 cm, there is an advantage that it can be applied to boxes of various different sizes.

FIG. 2B is an example in the case where the shape of the protrusion (notch) is complicated. In such a shape, it is conceivable that the dimensional division of each part in the shape becomes ambiguous. However, the technical idea of the present invention is that when almost the entire surface of the front plate covered with the cover piece is divided into two parts, a temporary fixing portion Q and a stripping control portion, the front plate has a longitudinal center portion and both ends. Since the stripping control part is provided in three places of the part and the area of the temporary fixing part Q is harmonized with the whole, the dimensions of Z1 to Z3 (L1, L2) and Y1, Y2 are set. The position division can be considered as shown in FIG. In general, a simple projection shape as shown in FIG. 2 (C) is sufficient. FIG. 2C is a schematic diagram of a specific embodiment.

As the locking member used for the temporary fastening portion Q of the present invention, any conventionally known locking member can be adopted. Among them, a coating film obtained by applying a cross-linkable curing varnish to an appropriate thickness and drying is preferable. strictly speaking, the radical polymerization type, addition polymerization, who it is UV-crosslinkable cure varnish typified by cationic polymerization of the crosslinkable curable resin varnish or the like, preferably made easily formed in various shapes .

Next, the recessed portion E provided on the back surface of the paperboard of the cover piece 5 at least at the position on both sides in the longitudinal direction of the cover piece 5 that overlaps (opposes) at least the temporary fixing portion Q is formed of a paperboard. May be processed so that the back surface protrudes from the front plate 1 side by about 0.1 to 1 mm, but any shape, area, and interval may be used as long as the paperboard is not broken. Further, the concave surface processed portion E may be arranged on the back surface of the paperboard portion of the cover piece 5 at a position not overlapping (not opposed to) the temporary fixing portion Q, or the back surface of the paperboard may be disposed on the front plate 1.
Concave processing portions that do not protrude to the side may be arranged in a mixture.

The reason is that the role of the concave surface processed portion E can be roughly classified into the following three roles. That is, the first role is to assist the film in contact with the temporary fixing portion Q by the projecting portion of the paperboard back surface, and the second is to make the cover piece paperboard of the portion parallel and horizontal by the process of forming unevenness. The role of correcting the degree of paperboard and increasing the rigidity of the paperboard, the third is the parallelism of the paperboard of the cover piece 5 by increasing the density of the paperboard by pressing to apply the processing, even in the concave processing where there is no protrusion on the back of the paperboard, It has been determined that each plays a role in correcting the deterioration of the levelness. This is because it is sufficient to take out the above roles alone or in combination according to the respective purposes. In particular, at least both sides in the longitudinal direction of the cover piece 5 serving as a starting point at the time of cutting are subjected to a concave surface processing having a protruding portion on the back surface of the paperboard serving the first or second role. If so, the other cover pieces may be appropriately concave-processed according to the necessity.

However, the projection height of the concave surface processing is 0.2 mm.
If you want to make it larger, make the concave shape a width dimension of 1 to 3.
It is desirable to form the groove in a narrow groove shape of the order of mm so as not to damage the paperboard. The number of grooves formed by the concave surface processing may be one, but it is preferable to arrange two to several grooves at intervals of about 3 to 10 mm perpendicular to the longitudinal direction of the cover piece. In this case, the length of the groove is selected from a range of 30 to 10 mm which does not reach the mounting position of the cutting tool. The concave surface processing in which a plurality of grooves are arranged as described above has an effect of sufficiently fulfilling the first and second roles in the processed area. Accordingly, a concave machining of the groove of the plural rows inwardly from both sides of the side end of Engai piece, which was placed in a range of about 50mm is to prevent skidding of the film edge at the start of cutting, skidding <br The effect of preventing the cutting ability of the cutting tool from decreasing due to the above is large and effective. In FIGS. 1A and 1B, the concave surface processed portion E
Are arranged in combination with three narrow groove-shaped concave surface processed portions E.

The paperboard used in the present invention has a thickness of 0.35 to 0.35.
About 1.5mm thick paper, generally thicker one is more rigid,
The strength is high and strong box is obtained, since the bending becomes difficult, usually a thickness 0.35～0.8Mm (basis weight 3
Ranging 10~550g / m ^2), a relatively thinner paperboard is employed. And the surface of the paperboard that is exposed on the surface of the box except for the part that becomes the glue allowance when assembling the box, such as the part of the auxiliary side plate, auxiliary side cover part, local joint, etc., In order to increase the water resistance of the box, it was general that the entire surface was treated with a water-resistant printing varnish, a transparent varnish, and the like. Front plate 1 and folded piece 14
In the fold line portion between the fold line and the center line, a so-called non-varnish-applied portion where a printing varnish, a transparent varnish, or the like is not applied is formed in a band-like range having a width of about 1 to 5 mm above and below the center line. It is desirable to keep.

The cutting tool K used in the present invention may be a metal straight saw blade shown in FIG. But,
This cutting tool is a so-called box type, which is a known box structure currently on the market, and is equipped with a V-shaped cutting tool K in which an imaginary line connecting the cutting edge to the tip of the V-shaped cover piece 5 is provided. When the present invention is applied to a storage box, the effect of solving the conventional problem that the finger is cut at the tip of the V-shaped blade protruding during the operation of picking (peeling) the film is greater.

The wrap film of the present invention is a general term for synthetic resin films, metal foils and thin papers used in food packaging. However, when applied to vinylidene chloride resin wrap films having strong self-adhesion, The effect is more remarkable and is desirable.

[0031]

The present invention will be further described below with reference to examples.

[0032]

Example 1 A thickness of about 0.5 mm ( basis weight 400 g /
Using a cardboard of m ² ) as a base material, a paperboard board for storage having a target of a box length of about 240 mm and a maximum portion having a structure shown in FIG. 1B was prepared. The difference between this mount and the conventional product is that a varnish for printing or a transparent varnish is applied to a band-shaped area having a width of about 3 mm above and below the center line at the fold line between the front plate 1 and the folded piece 14 during printing. 2 is formed at a position from 4 mm below the upper edge of the front plate to the cutting edge of the cutting tool K at the tip of the cover piece 5 from the position 4 mm below the upper edge of the front plate. (C) that the temporary fastening portion Q having the shape shown in FIG.
And about 30 mm from each side edge of the longitudinal sides of the cover piece 5,
Approximately 20 mm, approximately 10 mm, in the middle of the cover piece 5 having a width X, approximately 1 mm in width, approximately 13 mm in length, and approximately 0.3 mm in back projection size.
That is, three narrow groove-shaped concave portions E having a width of 2 mm were formed.

The specific size of the shape of the temporary fixing portion Q is Y
1 is about 7 mm, Y2 is about 20 mm, (Y2-Y1) is about 13 mm, that is, the width of Y1 is about one third of the width of Y2,
The corresponding length of the notch is that Z1 located at the center of the longitudinal direction is about 112 mm, and Z2 and Z3 located at both ends are about 3 mm.
2 mm, that is, the length L1 = L2 = about 30 mm of the protruding portion, the overall length of the front plate about 236 mm, and the width X to the cutting edge of the cover piece X = 2
4 mm.

The temporary fastening portion Q is formed by applying and drying an ultraviolet-crosslinkable curing varnish (trade name: Flash Dry, manufactured by Toyo Ink Mfg. Co., Ltd.). Then, a well-known box is formed, and a vinylidene chloride resin film (trade name: about 220 mm) wound around a paper tube (trade name:
Saran Wrap, manufactured by Asahi Kasei Corporation). As shown in FIG. 3B, this box body has the back surface of the opening piece 6 and the front plate 1.
When the local joining portion 9 that is bonded to the surface of FIG. 1 is pulled up and the unsealing piece 6 is removed from the perforated line 10 and opened, FIG.
The box shown in (A) was obtained. 500 boxes were prepared.

[0035]

[Comparative Example 1] A non-varnished portion at the upper edge of the front plate was not formed, and the shape of the temporary fixing portion Q was a rectangle having a width of about 15 mm and a length of about 70 mm, as compared with Example 1 described above. It is located at the longitudinal center of the front plate 1 covered with the cover piece 5 and the lower portion from a position 4 mm away from the upper edge of the front plate 1 to the cutting edge of the cutting tool K at the tip of the cover piece 5. A film storage box was prepared in which three points were changed in that the film storage box was disposed at the side position and that no concave processing portion E was provided in any part of the cover piece 5.

The film storage boxes prepared in Example 1 and Comparative Example 1 were distributed to monitors of 100 people, and the following comparison criteria for the following items such as film pull-out property and cutting property were evaluated according to the following evaluation criteria.
