2. Description of the Related Art Conventionally, a front plate 1, a bottom plate 2, as shown in FIG.
A rectangular storage chamber 13 formed by the rear plate 3 and the side plate 8 and having an upper opening, a lid plate 4 connected from a side edge of the rear plate 3 of the storage chamber 13 in a direction to cover the storage chamber opening, and A rectangular box body having a cover lid piece 5 extending from a side edge of the lid plate 4 in a direction to cover the front plate 1, and pulling out a necessary amount of the wrap film F from a winding film R stored in a storage chamber 13. A wrapping film storage box used by cutting with a cutting tool K arranged along a longitudinal direction of the box at a predetermined portion of the box is known, for example, as described in Japanese Utility Model Laid-Open No. 59-28022. . Most of the boxes of this kind are made of paperboard, and are formed by bending the plate surfaces of the respective parts substantially at right angles at the respective folding line portions. The side cover lid piece extending from the cover plate 4 to the side plate 8 is formed. 11
There are also those having the above-mentioned side cover lid piece 11. The cutting tool is arranged at the upper end portion of the front plate 1 and the front plate 1.
In many cases, the edge of each plate surface near the ridge between the bottom plate 2 and the bottom plate 2 or the tip portion of the covering lid piece 5 projects 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 ingredients include metal saw blades, plastic saw blades, paper saw blades (including hardened paper), paper saw blades with abrasive grains on the teeth,
A flat blade made of paper with fixed abrasive grains (without teeth) is known. As a method of deploying the cutting tool, a box-shaped small piece that is a cutting tool obtained by performing saw blade processing, abrasive grain fixing processing, etc. in advance, on a predetermined site plate when the box body is a flat paperboard, A method of fixing with caulking tools, adhesives, etc., or a predetermined part of the paperboard that will be the box directly on the paperboard itself, subjecting it to saw blade processing, abrasive grain fixing processing, etc.,
It is also widely known that there is a method of using a paperboard part of the box body as a cutting tool.

FIG. 2 does not have a side cover lid piece 11 extending from the cover plate 4 to the side plate 8 in the storage box. A metal saw blade K is provided on the back side of the tip of the cover lid piece 5. FIG. 2 (B) shows the storage box when it is fixed by the caulking tool 12.
2A is a stage in which the unsealing piece 6 is cut and removed at the cutting line 10 while the peeling of the unsealed piece 6 from the storage box is being promoted, and the film F is pulled out. It is a figure which shows a stage.

As a storage box in which a film temporary fixing function member is arranged on the front plate 1 covered with the cover lid piece 5, for example, the actual opening 5
In Japanese Laid-Open Utility Model Application No. 57-49430, in Japanese Patent Laid-Open No. 57-49430, a long member having a smooth surface such as a resin film layer or a metal foil layer is arranged in the box longitudinal direction on the upper surface of the front plate 1. Disposing the tacky adhesive layer member at one location on the surface of the front plate 1 at approximately the center in the longitudinal direction of the box is disclosed in JP-A-1-9.
In JP 151, it is proposed to employ a crosslinkable cured varnish for the temporary fastening function member having a smooth surface. Each of the film temporary fixing function members is related to the phenomenon that the cut end of the drawn film is rewound into the box due to the momentum when cutting (making it difficult to pull out the film next time). It has a function of stopping (preventing rewinding).

In the above-mentioned storage box in which a member for temporarily fixing the front plate 1 is arranged on the surface of the front plate 1, there is no way of thinking that the remaining portion of the front plate covered with the covering lid piece is used as a picking margin for the film.

[0006]

In the known storage box, the film locking at the temporary fastening (locking) part becomes too strong, and the film end may be peeled off from the locking part at the next drawing. It is difficult, and there is a problem that the cutting edge of the cutting tool damages the finger during the stripping operation. On the other hand, when cutting the drawn film from its side edge, the cutting performance of the side edge of the cutting tool, which is the starting point for cutting, may be lower than the design performance.If the side edge shape of the cut film is linear, There is a problem that it is not uniform and unsightly. This kind of defective phenomenon is remarkable in the storage box in which the cutting tool is provided at the tip of the cover piece.

An object of the present invention is to facilitate the stripping of the film without lowering the film locking ability at the temporary fastening portion, thereby preventing the finger from being scratched during the stripping operation and serving as a cutting starting point. It is an object of the present invention to provide a film storage box in which the cutting performance of a tool is prevented from deteriorating and the shapes of the cut film side edges are aligned in a straight line.

[0008]

SUMMARY OF THE INVENTION According to the present invention, a rectangular storage chamber 13 formed by a front plate 1, a bottom plate 2, a rear plate 3 and a side plate 8 and having an open top is provided, and a rear storage chamber 13 therefor. A rectangular box body having a lid plate 4 connected from a side edge of the plate 3 in a direction to cover the opening of the storage chamber, and a cover lid piece 5 extending from a side edge of the lid plate 4 in a direction to cover the front plate 1. Therefore, a necessary amount of the wrap film F is drawn from the winding film R stored in the storage chamber 13, and is cut by a cutting tool K provided along a longitudinal direction of the box at a predetermined portion of the box for use. In the storage box of the wrap film, the front of the front plate 1 covered with the cover lid piece 5 and at least one side of the upper edge of the front plate forming the opening of the storage chamber, at a portion within a range of 3 cm Cover with the lid lid piece 5 at a position up to 50% of the front plate width dimension of the portion covered by the lid lid piece 5 from the upper edge of the board. The width of the front plate is 50% or less, and the film temporary fastening function member is arranged in a portion extending from one side of the front plate 1 to the other side in the longitudinal direction of the front plate. A wrap film storage box.

FIG. 1 shows an embodiment of the present invention.
FIG. 1A is a schematic perspective view illustrating a storage box, and FIG.
It is a plane schematic diagram of the mount which becomes the storage box of FIG. 1 (A). In FIG. 1 (A), the storage box itself is a rectangular storage chamber 13 formed by a front plate 1, a bottom plate 2, a rear plate 3, and a side plate 8 with an open top, and a rear plate of the storage chamber 13. A rectangular box body having a lid plate 4 connected from the side edge of 3 in the direction of covering the storage chamber opening, and a cover lid piece 5 extending in the direction of covering the front plate 1 from the side edge of the lid plate 4, Pull out the required amount of wrap film F from the winding film R stored in the storage chamber 13,
A storage box for a wrap film used by cutting with a cutting tool K provided at a predetermined portion of the box along the longitudinal direction of the box. FIG. 1 (A) shows a box in a state in which the back surface of the unsealing piece 6 and the front surface of the front plate 1 are stuck together, the local joint portion 9 is pulled over, and the unsealing piece 6 is removed from the cut line 10 to open the box. ing.
More specifically, it has a side cover lid piece 11 extending from the cover plate 4 in a direction to cover the side plate 8, and is made of metal on the back surface side of the tip edge portion of the cover lid piece 5 along the longitudinal direction of the rectangular box body. Caulking tool for saw blade 1
It is a storage box when fixed at 2.

The structure of the storage box with the cutting tool described above is a part in common with a known storage box, and can be appropriately replaced with, for example, the known storage box described in the section of the prior art. The method of cutting the film F pulled out from the storage box is as follows. The film connected to the winding film R is sandwiched between the front plate 1 and the cover lid piece 5, and the central portion of the cover lid piece 5 is pressed with a thumb to fix it. With the blade of the cutting tool K at the tip, the film on the drawer end side is guided upward so that the angle formed between the films is approximately 45 degrees or less, and one side edge of the cutting tool is further applied while applying tension to the film. The box body and / or the film is obliquely guided and operated in the direction in which the blade edge of the blade penetrates the film in contact therewith. By this operation, the film is generally sequentially cut along the blade edge from the film side edge side which is in contact with the blade edge of one side edge of the cutter toward the other side edge side. Then, the remaining film sandwiched between the front plate 1 and the cover lid piece 5 becomes the next drawing end.

The difference of the present invention from the conventional products is as follows: a) A part of the upper edge of the front plate forming the opening of the storage chamber, which is at least one side within a range of 3 cm or less from the side edge, and b) the cover piece 5 Width of 50% or less of the width of the front plate covered with the cover lid piece 5 at a position up to 50% of the front plate width dimension of the portion covered by the cover lid piece 5 on the surface of the front plate 1 covered with That is, the provisional fastening function members Q ′ and Q of the film are arranged in a portion having a dimension and extending in the longitudinal direction of the front plate from one side to the other side of the front plate 1.

[0012]

The role played by the structure of the present invention will be described by classifying it into the above requirements a) and b). The main role of requirement a) is that the film is located at the upper edge of the front plate 1 at the start of cutting the film. Is to exert a temporary fastening action that does not skid along the upper edge of the front plate especially at the side edge of the film, which causes the side edge of the film not to converge and to contact the cutting edge of the side edge of the cutting tool. Moreover, since the film tensioned by the tension is cut, it is possible to prevent the cutting performance of the cutting tool from deteriorating, and the shapes of the film side edges cut on the cutting tool become straight. It is also possible to prevent the film from being rewound into the box due to the momentum when cutting.

The requirements b) mainly play the role of a locking portion having a strong temporary fixing function located on the upper side of the front plate 1 covered with the covering lid piece 5 and the lower side of the front plate 1 covered with the covering lid piece. By the action of the portion where the side locking portion does not exist, the film locking capability of the temporary fastening portion is not reduced and the film can be easily peeled off from the front plate. That is, by making the width of the temporary fastening portion narrower than that of the conventional temporary fastening portion, the distance between the temporary fastening portion Q and the cutting blade is increased and a sufficient picking margin is secured, and by making it long, the picking portion can be picked from anywhere in the longitudinal direction of the box. .

Conditions to be satisfied by the requirements a) and b) will be described below. All the conventionally known members can be adopted as the temporary fastening function members that are commonly used for the requirements a) and b). However, in order to have both the temporary fixing function of the film and the durability of the temporary fixing function, for example, the non-adhesive surface of the single-sided adhesive tape, the surface of the resin film, the surface of the metal foil, etc., rather than the use of an adhesive type adhesive resin layer. The self-adhesiveness on the wrap film side evokes the self-adhesiveness on the side of the wrap film due to the smooth surface, while the self-adhesiveness of the wrap film causes the temporary fastening function ( It is preferable to employ a smooth surface member (adhesive type). Further, a cross-linkable hardened varnish is added to a thickness of 5 to 2
It is more preferable to employ a resin layer member having a thickness of 5 μm, preferably 5 to 10 μm, in order to economically supply the box body.

What effectively contributes to the role of preventing the film from skidding is the requirement a), that is, the temporary fastening function member Q'located at the upper edge of the front plate. The provisional fastening function member Q'is formed so that it can be bent at the tip of the front plate 1, such as the mount shown in FIG. 1B, rather than the cut surface of the paperboard cut out at the upper end of the front plate. The folding piece 14 arranged in the above manner is bent and attached to the back side of the front plate 1, and the case where the spine of the bent fold line is the upper edge of the front plate is the temporary fastening function member. It is preferable because the surface can be formed smoothly on a wide edge portion (corresponding to the paper thickness). At this time, the arrangement of the temporary fastening function member is
For example, the protrusions are often placed slightly on the front plate or the folded piece, but this protrusion (particularly the protrusion on the front plate)
May act as a film locking ability on the front plate surface, so that it is preferable to keep it in a small area. The temporary fastening functional member Q'disposed on the upper edge of the front plate is essentially required to be at one end in the box longitudinal direction. However, if it is left to the discretion of the consumer to choose whether to use either end of the box (cutting tool) as the cutting start point of the film, it may be placed on both sides of the upper edge of the front plate. preferable. The reason why the size of the temporary fastening function member Q'disposed on the upper edge of the front plate is "the part within the range of 3 cm or less from the side edge of the opening" is to prevent the skid of the film from interfering with the drawability of the film. In order to exert the effect without doing so, it is preferably 2 cm or less. If this dimension is made longer, a squeak noise will be produced when the film is pulled out, and the drawability will be significantly impaired. On the contrary, if it is too short, the effect of preventing the sideslip of the film will not be exhibited. Moreover, the portion of the opening that is less than about 5 mm on the most side is strictly the film because of the relationship between the length of the paper core of the wound film, the width and position of the wound film, and the length of the paper core and the internal dimensions of the opening. There are many portions that do not come into contact, and it is difficult to expect the role of the temporary fastening function member in this portion that does not come into contact. In addition, the property of engaging with the temporary fastening function member is greatly influenced by the target film type. Therefore, it is most preferable to set the size and position of Q ′ so that the size of the temporary fastening function member portion that substantially contacts the film at the time of drawing out is about 0.5 to 1 cm in consideration of the above matters. preferable. What is important next is requirement b), that is, the shape of the temporary fastening function member Q is narrower and longer than the conventional one. By making the width narrower, the distance between the temporary fastening function member Q and the cutting blade is increased, and the picking margin of the film can be secured. The width of the temporary fastening function member Q is 50% or less of the width of the surface of the front plate 1 covered with the covering lid piece 5.
Even if it is 50% or more, there is not much difference in the rewinding prevention effect, and the picking margin of the film becomes insufficient. Next, the lengthened effect will be described. A cover piece 5 for cutting a normal film
Since the center of the is fixed with the thumb, the temporary fastening function member Q is often arranged in the center. In that case, there is a high probability that both ends of the film will be starting points when the film is rewound into the box by the momentum after cutting. If the areas of the temporary fastening function members Q are the same, the long length extending to both side edges in the longitudinal direction of the front plate 1 is more effective than the centrally arranging in the central portion. large. That is, by making the temporary fastening function member Q thin and long, the film can be picked up from anywhere in the longitudinal direction of the box while maintaining the rewinding prevention effect. The distance between the temporary fastening function member Q and the upper edge of the front plate is preferably 2 to 10 mm. From the upper edge of the front plate to the cover piece 5
By being positioned up to 50% of the width of the front plate of the portion covered with, there is an effect of preventing the film side slip when the film is cut and an effect of securing the picking margin. If it is less than 2 mm, a squeak noise will be produced when the film is pulled out, and the drawability will be hindered. If it exceeds 10 mm, a sufficient picking margin cannot be secured. The width of the temporary fastening function member Q is 0.5 to 1.
It is preferably 5 cm and 20% to 40% of the width of the front plate covered with the lid piece. The length is generally 16 to 46 cm, but the width of the film to be stored (for example, 15 cm, 22 cm, 30 c
m, 45 cm), the size of the box body according to the length of the roll, the structure of the box body, the length dimension of the film picking portion, and the like. That is, the size of the temporary fastening function member Q is longer when the length of the box body is larger, is wider when the width of the covering lid piece that covers the front plate is larger, and the minimum required area (generally 10 to 50 cm) as a whole. ² ) to make a simple strip shape. This is because the provision of the temporary fastening function member Q is easy and economical, and the provision of the temporary fastening function member Q having an excessively large area hinders the peeling (picking) operation of the film for pulling out. It is a measure against things. Crosslinking of the crosslinkable cured varnish used here is performed by electron beam irradiation, ultraviolet ray irradiation, heat ray irradiation, or the like. This crosslinking method is excellent in that it is easy to use ultraviolet irradiation crosslinking although it depends on the type of varnish used. Examples of the ultraviolet irradiation type crosslinkable curing varnish include radical polymerization type, addition polymerization type, and cationic polymerization type crosslinkable curing varnish. Epoxy acrylate, polyester acrylate, polyurethane acrylate, silicone acrylate, polyol type Radical-polymerizable acrylic modified resins represented by acrylates and alkyd acrylates are generally used.

The paperboard used in the present invention has a thickness of 0.35.
The thickness is about 1.5 mm. Generally, the thicker the wall, the more rigid and strong the box is obtained, but the bending process becomes difficult. Thickness 0.35-0.8 mm (31 by weight)
A relatively thin paperboard of 0-550 g / m ² ) is adopted. And conventionally, the surface part of the paperboard that will be exposed on the surface of the box body, except for the part that serves as the glue margin at the time of box assembly, such as a part of the auxiliary side plate, the auxiliary side cover lid piece, the local joint part, etc. In general, the entire surface of the box is treated with a water-resistant printing varnish, a transparent varnish or the like in order to enhance the water resistance of the box. In order to further improve the performance of the storage box of the present invention with respect to this conventional product,
In the fold line portion between the front plate 1 and the folding piece 14, the fold line is the center line and the strip-like range of about 1 to 5 mm width is provided below.
This is to form a so-called non-varnish-coated portion where no printing varnish or transparent varnish is applied. This measure leads to the effect of enhancing the drawability at the time of drawing the next film.

The cutting tool used in the present invention may be the metallic straight saw blade shown in FIG. However, the box structure currently on the market is called a so-called box type, and a storage box equipped with a V-shaped cutting tool K with a V-shaped virtual line connecting the blade tip to the tip of the V-shaped covering lid piece 5. When it is applied, the effect of eliminating the "problem that the finger tip is cut by the protruding V-shaped blade tip" during the film picking (peeling) operation is greater.

The wrap film referred to in the present invention is a generic name for synthetic resin films, metal foils, thin papers, etc. used for food packaging. The vinylidene chloride resin wrap film having a strong self-adhesion is more effective. It is preferable because it is remarkable.

[Example] Meat thickness of about 0.5 mm (weighing 400 g / m ² ).
Using the cardboard of No. 3 as a base material, a paperboard mount for storage having a box length of about 31 cm having the structure shown in FIG. 1B was prepared. The difference between this mount and the conventional product is that the fold line between the front plate 1 and the folded piece 14 is used as the center line during the printing process, and a printing varnish or a transparent varnish is formed in a strip-shaped range having a width of about 3 mm above and below the center line. Approximately 3 m above the point where a non-varnished part where no varnish was applied was formed
On both sides of the m-shaped strip-shaped non-varnished part, a cross-linkable cured varnish with a width of about 3 mm (corresponding to Q ', manufactured by Toyo Ink Mfg. Co., Ltd. Flash dry, UV crosslinkable curing varnish manufactured by Co., Ltd.) was applied to a coating thickness of 6 to 8 μm and solidified. Further, on the surface of the front plate 1 covered with the cover piece 5, at a position 5 mm from the upper edge of the front plate, a width of about 0.7 cm and a length of about 30.9 cm (an area of about 21.6 cm).
