Detailed Description of the Invention

[0001]

[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 13 formed by the rear plate 3 and the side plate 8 and having an upper opening, and a lid plate 4 connected from the side edge of the rear plate 3 of the storage chamber 13 in a direction to cover the storage chamber opening. Its lid plate 4
Is a rectangular box having a cover piece 5 extending in a direction covering the front plate 1 from the side edge of, and pulling out a necessary amount of the wrap film F from the winding film R stored in the storage chamber 13,
A wrap film storage box used by cutting with a cutting tool K provided at a predetermined portion of the box along the longitudinal direction 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. 1
There is also one having 1 or not having the side cover lid piece 11 described above. The cutting tool is arranged at the upper end of the front plate 1, in the vicinity of the ridge between the front plate 1 and the bottom plate 2, and at the tip of the covering lid piece 5, the blade edge of each plate surface protruding from the plate surface. There are many things. 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 are metal saw blades, plastic saw blades, paper saw blades (including vulcanized hardened paper), paper saw blades with abrasive grains on the teeth, and flat blades with fixed abrasive grains. Existence such as (no teeth) is known.

Further, as a method of disposing the cutting tool, a box-shaped small piece, which is a cutting tool obtained by previously performing saw blade processing, abrasive grain fixing processing, etc., is determined at a stage when the box body is a flat paperboard. 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. A method of making a paperboard into a cutting tool is widely known.

FIG. 3 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. 3 shows the storage box when it is fixed by the caulking tool 12.
3B is a stage in which the unsealing piece 6 is cut and removed along the cutting line 10 while the peeling of the unsealed piece 6 from the storage box is being proceeded, and the film F is unsealed in FIG. 3A. It is a figure which shows the stage which pulled out.

Further, as a storage box in which a temporary holding portion Q of the film is arranged on the front plate 1 covered with the cover piece 5, for example, in Japanese Utility Model Laid-Open No. 54-80430, the surface smoothness of a resin film layer, a metal foil layer, etc. is disclosed. In Japanese Utility Model Laid-Open No. 57-49430, a sticky adhesive layer is formed on the upper surface of the front plate 1 substantially in the longitudinal direction of the box on the surface of the front plate 1. The arrangement in one place in the central portion is disclosed in Japanese Patent Laid-Open No.
JP-A-151-151 proposes to apply a crosslinkable cured varnish to the temporary fastening portion so that the surface is smooth.

In each of the temporary holding portions Q of the film, the phenomenon that the cut end of the drawn film is rewound into the box due to the bounce at the time of cutting (the next drawing becomes difficult) is easy to peel the film. It has a function of locking (rewinding prevention) in the state. In addition, each of the conventional proposals has always been to increase the locking force of the temporary fastening portion and dispose the temporary fastening portion having a relatively small area shape such as a circle or a square in the central portion in the longitudinal direction of the box.

[0007]

However, in the above-mentioned conventional storage box, the temporary holding (locking) portion lacks the locking force as viewed from the entire film width, and therefore, there is a bounce when cutting or lifting the lid. Although the film is likely to be rewound, the adhesive force becomes too strong at the local area where the film is locked, and it is not easy to peel off the film edge from the locking part during the next withdrawal. There are problems that the operability of pulling out is deteriorated, a problem that a vertical tearing phenomenon of the film is induced during the stripping operation, and the treatment is difficult, or a finger of the cutting tool is injured.

On the other hand, when the drawn film is cut from the side edge, the problem that the cutting performance of the side edge of the cutting tool, which is the starting point of cutting, is lower than the design performance, and the shape of the side edge of the cut film There is also a problem in that the lines are not straight and the lines are uneven 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 phenomenon of vertical tearing of the film during the stripping operation and the problem of scratching the fingers, and further It is an object of the present invention to provide a film storage box in which the cutting performance of a cutting tool serving as a cutting start point is prevented from being deteriorated and the side edges of the cut film are linearly aligned.

[0009]

The present invention requires the following configurations in order to achieve the above object. That is, according to the present invention, a rectangular storage chamber 13 formed by the front plate 1, the bottom plate 2, the rear plate 3, and the side plate 8 and having an open upper portion, and a side edge of the rear plate 3 of the storage chamber 13 are stored. A lid plate 4 connected in a direction to cover the chamber opening, 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 a surface of the front plate 1 covered with the cover lid piece 5 is cut. A rectangular box having a temporary fastening portion Q for locking a rear film, and extracting a necessary amount of the wrap film F from the winding film R stored in the storage chamber 13 and disposing the wrap film F at the tip of the covering lid piece 5. In the storage box of the wrap film used by cutting with the cutting tool K, the temporary fastening portion Q is placed at the blade tip of the cutting tool K at the tip of the covering lid piece 5 from a position 3 to 6 mm away from the upper edge of the front plate 1. It is arranged at all the positions, and its shape is a band extending over the entire length of the box. Notches having a width of approximately 1/2 to 3/4 of the width of the strip and a corresponding length in the longitudinal direction are provided at three locations of the central longitudinal portion and both longitudinal end portions of the body, and two resulting cutout portions are provided. A storage box for a wrap film, characterized in that the protrusion is arranged so that its top is formed toward the bottom plate side of the box.

The present invention will be described in detail below. FIG. 1 shows an embodiment of the present invention, FIG. 1 (A) is a schematic perspective view illustrating a storage box, and FIG. 1 (B) is a schematic plan view of a mount that becomes the storage box of FIG. 1 (A). Is. FIG. 1 illustrates the present invention.
In (A), the storage box itself has 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, and a rear plate 3 of the storage chamber 13. A rectangular box body having a lid plate 4 connected from a side edge of the lid plate in a direction of covering the opening of the storage chamber and a covering lid piece 5 extending from a side edge of the lid plate 4 in a direction of covering the front plate 1, This is a storage box for a wrap film that is used by drawing out a required amount of the wrap film F from the winding film R stored in the chamber 13 and cutting it with a cutting tool K provided at the tip of the covering lid piece 5.

However, the box body of FIG. 1 (A) is shown in FIG.
Similar to the conventional product shown in (B), the back surface of the unsealing piece 6 and the front plate 1
It is shown as a box in a state in which the local joint portion 9 that is bonded to the surface of is cut off, the opening piece 6 is removed from the cut line 10, and the opening is opened. 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 the cutting tool K is provided 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.
An example of the storage box in which the metal saw blade is fixed by the caulking tool 12 is illustrated. The structure of the storage box with a cutting tool described above is common to the known storage box, and therefore can be appropriately replaced with, for example, the known storage box described in the section of the prior art.

Further, in the method of cutting the film F pulled out from the storage box of this kind, the film continuous to the winding film R is sandwiched between the front plate 1 and the cover lid piece 5, and the substantially central portion of the cover lid piece 5 is cut. Hold it down with your thumb to fix it, pull out the edge of the cutting tool K at the tip of the cover lid into an acute angle of 45 degrees or less between the films, and guide the end film upwards,
Further, while applying tension to the film, the box body or the film is obliquely guided and operated in a direction in which the blade edge at one side of the cutting tool K penetrates the film in contact with it.

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. And, the present invention is different from the conventional product in that (1) the temporary fastening portion Q is
The position from the lower position 3 to 6 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 covering lid piece 5, (2) The shape of the temporary fastening portion Q is A strip that extends the entire length of the strip, and the length of the strip is 3
A notch having a width of approximately 1/2 to 3/4 of the width of the strip and a corresponding length in the longitudinal direction is provided at several places, and the resulting 2
The two protrusions are strips whose tops are formed so as to face the bottom plate side of the box.

[0014]

The role of the above-described structure of the present invention is that the film is locked (rolled) at any one of the temporary fastening portions Q in the longitudinal direction of the front plate 1 at the portion covered by the covering lid piece 5 of the front plate 1 when the film is cut. In addition to surely exhibiting the effect of preventing return, at the time of peeling off the locked film, the notch portions having the corresponding lengths arranged at three places exert the effect of facilitating the picking. As a result, both the reliable function of preventing rewinding and the ease of taking out the film from the box body are realized.

In general, even if the wrap storage box is limited to this type of box body, for example, whether the working hand is right or left, the operation method for handling the box body at the time of cutting, the position of the finger to be placed in the box, the picking at the time of peeling It is convenient for consumers in terms of the picking position, the order of stripping, etc., and its usage varies widely. Therefore, the above-mentioned structure is the same as the conventional level in researching the relationship between the position of the film F with respect to the front plate 1 and the movement of the film F when using all of these methods. A temporary fastening part that exhibits a more reliable function of preventing rewinding, yet can easily strip (take out) the film F, and can secure the cutting ability of the cutting tool K and the drawability of the film F from the box. The position and shape of Q are investigated.

2A and 2B are schematic plan views of the front plate 1 showing the arrangement and shape of the temporary fastening portions Q of the present invention. FIG. 2A shows the basic concept and FIG. 2B shows an example of changing the shape. 2C shows a concrete example thereof. First, in FIG. 2 (A), the temporary fastening portion Q of the present invention is located at a lower position (in X) from the upper edge of the front plate 1 to the cutting edge of the tip cutting tool K of the covering lid piece covering the front plate 1. (Correspondingly), it is necessary to be arranged below a position 3 to 6 mm (corresponding to X1) away from the upper edge of the front plate. This front plate 1
It is necessary to be arranged at a position (corresponding to X) from the upper part of the covering lid piece 5 that covers the covering piece 5 to the cutting edge of the cutting tool K when pressing the covering lid piece 5 with a finger during cutting. , Plays a role of increasing the accuracy with which the film is brought into contact and locked with the temporary fastening portion Q. In other words, no matter which position of the lid lid piece 5 is pressed, the film comes into contact with the temporary fastening portion Q extending along the entire length in the longitudinal direction of the box body, so that the accuracy of locking is increased. .

Further, X1 = 3 to 6 m from the upper edge of the front plate 1.
The necessity of disposing the temporary fastening part Q below the position m away from the film suppresses the reduction in the drawability of the film from the box body caused by the provision of the temporary fastening part Q, and further the film F at the time of cutting.
To prevent the skid of the cutting tool K from slipping, thereby maintaining the cutting ability of the cutting tool K. In addition, it is necessary to stop the band width of the temporary fastening portion Q at this time up to the cutting edge of the cutting tool K at the tip of the covering lid piece 5, even in the case of a wide protruding portion. Rather, it is preferable that the film is positioned 2 to 6 mm inward of the cutting edge so as to prevent vertical tearing of the uncut film.

The widths Y1 and Y2 of the band of the temporary fastening portion Q and the width (Y2-Y1) of the notch of the band are the widths from the upper edge of the front plate 1 to the cutting edge of the covering lid piece 5 adopted. (Corresponding to X) and the entire box (depending on the relationship between the film width and the winding amount)
It is determined by the size of. Generally, Y1 is 5-15
mm, Y2 is 15 to 30 mm, (Y2-Y1) is 5 to 1
It is selected from the range of 5 mm. At this time, when Y2 is the maximum width of the strip, the width of Y1 is 1/2 to 1 / of the maximum width Y2.
It is necessary to select the width dimension (Y2-Y1) of the notch in the range of 4.

The length of the notch in the longitudinal direction is such that the length Z1 located at the longitudinal center of the box is 50 to 160 mm, and the lengths Z2 and Z3 located at both ends are 10 to 90 mm. Yes, this is selected according to the longitudinal dimension of the target box (depending on the film width relationship). As a result, the lengths L1 and L2 of the two protrusions in the longitudinal direction are 25 to 12
It is selected in the range of 0 mm. The lengths Z1 to Z3 in the longitudinal direction of the cutout portions may be the same length dimension or different dimensions, but the central portion Z1 is 80 to 150 m.
It is desirable to make it longer than m and make Z2 and Z3 shorter than Z1. In short, the portions Z1 to Z3 are portions for facilitating the stripping (removal) of the film, and the entire strip including the protrusions is a portion for exhibiting a reliable rewinding prevention functional effect. In other words, the both harmony is achieved by the shape and the size of the area of both, and the portion of the temporary fastening portion Q which reaches the end of the box body while being narrowed by the notches at both ends is cut. The lateral deviation of the film end portion at the start is prevented, and the cutting ability of the cutting tool K due to the lateral deviation is prevented.
The cut-out part is the starting point when peeling the film from the locking part and the area of easy peeling, with the top of the cut-out facing the bottom plate side of the box. The entire band having the projections of the two crests formed plays a role of locking the film by any one of the cutting operations of pressing the covering lid piece 5. Therefore, in the temporary fastening portion Q of the present invention, the width dimension of the film to be stored is, for example, 15 cm, 22 cm, 30 cm, 45.
There is an advantage that it can be widely applied to boxes of various sizes in the case of cm.

FIG. 2B shows an example in which the shapes of the protrusion and the notch are complicated. With such a shape, it is considered that the size division of each part in the shape becomes ambiguous,
The technical idea of the present invention is that almost the entire surface of the front plate 1 covered with the covering piece 5 is used as the temporary fastening portion Q and the stripping target portion.
When dividing, the idea is to provide stripping target portions at three locations, the central portion and both end portions in the longitudinal direction of the front plate 1, so as to achieve area harmony with the portion of the temporary fastening portion Q with respect to the whole. ,
The dimensional position divisions of Z1 to Z3 (L1, L2) and Y1, Y2 can be considered as shown in FIG. 2 (B).

In general, a simple shape is sufficient for this shape, and FIG. 2C is a schematic view of a concrete example thereof.
As the member used for the temporary holding portion Q of the present invention, all conventionally known members can be adopted, but among them, a coating film obtained by applying a crosslinkable cured varnish with an appropriate thickness and drying it is preferable. Specifically, it is desirable that the UV-curable curable varnish represented by a radical-curable, addition-polymerizable, or cationic-polymerizable cross-linkable resin varnish can be easily formed into various shapes.

The paperboard used in the present invention has a thickness of 0.35.
Generally, a thicker paper with a thickness of about 1.5 mm and a thicker one can provide a stronger and stronger box. However, it is difficult to fold it, so the thickness is usually 0.35 to 0.8 mm (weighing 3
A relatively thin paperboard in the range of 10 to 550 g / m ² ) is used. The surface of the paperboard, which is a part of the auxiliary side plate, the auxiliary side cover lid piece, the local joint, etc., that is exposed on the surface of the box body excluding the portion that serves as the glue margin during box assembly is Water-resistant printing varnish to increase water resistance,
Ordinarily, the entire surface is treated with a transparent varnish or the like. In contrast to the conventional product, the storage box of the present invention has a front plate 1 and a folding piece 1 in order to further enhance the film drawing performance.
4, a so-called non-varnish coating portion is formed in which a printing varnish, a transparent varnish, etc. are not applied in a belt-like area having a width of about 1 to 5 mm above and below the fold line. That is desirable.

The cutting tool K used in the storage box of the present invention is shown in FIG.
It may be a metallic straight saw blade shown in FIG.
However, the cutting tool K having a V-shaped cutting edge at the tip of the cover lid piece 5 which is currently commercially available and is attached to a known so-called box type box structure can be applied to the storage box of the present invention. For example, by providing the temporary fastening portion Q, it is possible to solve the conventional problem that the fingers are cut by the protruding V-shaped blade when the film is picked (peeled off).

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