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; The lid plate 4
Is a rectangular box having a cover piece 5 extending in a direction to cover the front plate 1 from the side edge of the wrap film R stored in the storage chamber 13 and a required amount of the wrap film F is drawn out.
A wrap film storage box cut and used by a cutting tool K provided at a predetermined portion of the box along the length of the box is used, for example, as described in Japanese Utility Model Laid-Open No. 59-28022. 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. There is a case where the side cover 11 is provided, or a case where the side cover cover 11 is not provided. The disposition position of the cutting tool is a position where the blade edge of any one of the plate surfaces of the upper end portion of the front plate 1, the vicinity of the ridge between the front plate 1 and the bottom plate 2, and 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 (the shape of the imaginary line connecting the cutting edges) is straight, concave, convex, 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. A method of using paperboard as a cutting tool is widely known.

[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. 3 shows a storage box when the storage box is fixed by the caulking device 12.
(B), cut the opening piece 6 from the storage box along the perforated line 10 while advancing the peeling of the local joint 9 and open it.
The step of the cormorants, 3 (A) is a diagram showing a step of pulling out the film F is opened.

[0005] Further, as a storage box in which a temporary fixing portion Q of a film is disposed 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 having a smooth surface such as a resin film layer or a metal foil layer. In Japanese Utility Model Laid-Open Publication No. S57-49430, it is described that a long member is disposed in the longitudinal direction of the box on the upper surface of the front plate 1. placing the one place in the central portion, JP-1-9
No. 151 proposes applying a crosslinkable hardening varnish to the temporary fixing portion so as to have a smooth surface.

[0006] Any of the temporary fastening portions Q of the film is such that 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), and the film is easily peeled off. A function of locking (preventing rewinding) in the state is provided. And each conventional proposal has always raised the locking force of a temporary fixing part, and arrange | positioned the temporary fixing part of a comparatively small area shape, such as a circle and a square, in the center part of the box body longitudinal direction.

[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 the drawn film is cut from the side edge, the cutting performance at the side of the cutting tool, which is the starting point of cutting, is lower than the designed performance. However, there is also a problem that it is not straight and 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. An object of the present invention is, without reducing the film engaging capacity of the temporary catch facilitates the peeling picking of the film, preventing thereby peeling picking operation during Tate裂only phenomena and finger damage problem of the film, even prevent deterioration of the cutting performance of the cutting tool as the cutting start point, the shape of the side end portion of the cut film is to provide a storage box improved wrapping film to align in a straight line.

[0009]

According to the present invention, the following arrangement is required 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. A cover plate 4 connected in a direction to cover the chamber opening, a cover piece 5 extending from a side edge of the cover plate 4 in a direction to cover the front plate 1, and a surface of the front plate 1 covered with the cover piece 5 is cut. It is a rectangular box having a temporary fixing portion Q for locking the rear film, and a required amount of the wrap film F is pulled out from the rolled film R stored in the storage chamber 13 and disposed at the tip of the cover piece 5. In the storage box of the wrap film to be cut and used with the cutting tool K, the temporary fixing portion Q is attached to the cutting edge of the cutting tool K at the tip of the cover piece 5 from a position 3 to 6 mm away from the upper edge of the front plate 1. And the shape of the strip is extended along the entire length of the box. Three notches having a width of approximately 1/2 to 3/4 of the width of the band and a corresponding length in the longitudinal direction are provided at three places at the center and at both ends of the body. A storage box for a wrap film, characterized in that the projections are arranged so that their peaks face the bottom plate side of the box.

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.
Is illustrated with a storage box in which a metal saw blade is fixed with a swaging tool 12. 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 cut. 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 an acute angle of 45 degrees or less between the films, guide the film on the end side upward,
Further, while applying tension to the film, the box or the film is guided obliquely in a direction in which the cutting edge of one side end of the cutting tool K cuts through the film that abuts the cutting tool.

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 difference between the present invention and the conventional product is that (1) the temporary fastening portion Q
(2) The shape of the temporary fixing portion Q is defined by the shape of the box body, and the position from the lower position 3-6 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 cover piece 5. A belt extending over the entire length of the belt, and a 3
At two places, a notch having a width of approximately 1/2 to 3/4 of the width of the band and a corresponding length in the longitudinal direction is provided.
One of the projections is a band whose top is formed toward the bottom plate of the box.

[0014]

The role of the above-mentioned structure of the present invention is that the film is locked (wound) by a temporary fixing portion Q in the longitudinal direction of the front plate 1 at a portion covered by the front plate 1 and the cover piece 5 when cutting the film. In addition to reliably exhibiting the effect of preventing the return of the film, at the time of peeling off the locked film, the notches having the corresponding lengths arranged at three places have the effect of facilitating the picking. As a result, it is possible to realize both the functional effect of reliably preventing unwinding and the ease of peeling the film from the box.

[0015] In general, even if only in the box storage box is of this kind of wrap film, for example, interest-out hand or right or left, the operation how to handle the box body at the time of cutting, the position of the finger to put in a box, picking strip Consumers are easy to use in terms of the picking position at the time, the order of stripping, and the like, and the manner in which they are used varies. Therefore,
The above-described configuration is more reliable than the conventional level in any use in studying the relationship between the position of the film F with respect to the front plate 1 and its movement when all of these uses are performed. Of the temporary fastening portion Q that exhibits a functional effect of preventing unwinding, yet can easily peel off (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 were determined.

FIG. 2 is a schematic plan view of the front plate 1 showing the arrangement and shape of the temporary fastening portion Q of the present invention. FIG. 2A shows the basic concept, and FIG. FIG. 2C shows a specific example thereof. First, in FIG. 2 (A), the temporary fixing portion Q of the present invention is located at a lower position (X on the surface of the front plate 1 from the upper edge of the front plate 1 to the cutting edge of the tip cutting tool K of the cover piece covering the front plate 1). Correspondingly), it is necessary to be disposed below from a position 3-6 mm (corresponding to X1) away from the upper edge of the front plate. This front plate 1
Need to be arranged at a position (corresponding to X) to the cutting edge of the cutting tool K at the tip of the cover piece 5 covering the cover piece 5 from above to below, when the cover piece 5 is pressed with a finger during cutting. , And plays a role in increasing the accuracy of the contact of the film with the temporary fastening portion Q. That is, regardless of which position of the cover piece 5 is pressed, the film comes into contact with the temporary fixing portion Q extending over the entire length in the longitudinal direction of the box, thereby increasing the accuracy of locking. .

X1 = 3 to 6 m from the upper edge of the front plate 1
The necessity of arranging the temporary fastening portion Q from a position apart from a position m away from the center prevents the film from being pulled out from the box caused by the provision of the temporary fastening portion Q, and furthermore, the film F at the time of cutting.
In order to prevent the sideslip of the cutting tool K, thereby maintaining the cutting ability of the cutting tool K. In this case, it is necessary to stop the band width of the temporary fixing portion Q even at a wide projection portion to the cutting edge of the cutting tool K at the tip of the cover piece 5. Rather, it is desirable to stop the film 2 to 6 mm inward from the cutting edge in order to prevent longitudinal tearing of the remaining film.

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

The length of the cutout 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). The resulting 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 of the cutouts in the longitudinal direction may be the same length or may be different, but Z1 at the center is 80 to 150 m.
It is desirable that the length is set as long as m and Z2 and Z3 are made shorter than Z1. In short, the portions Z1 to Z3 are portions that facilitate peeling-out (take-out) of the film, and the entire band including the projections corresponds to a portion that exhibits a function of reliably preventing unwinding. In other words, the harmony between the two is achieved by the shape and the size of the area, and the portion of the temporary fixing portion Q which reaches the end of the box while being narrowed by the notches at both ends is cut off. Prevent side slip of the film end at the start, and prevent the cutting ability of the cutting tool K from decreasing due to the side slip .
And the part cut out by the notch is the starting point when peeling off the film from the locking part and the area of ease of stripping, with the notch part facing the bottom plate side of the box. The whole of the formed band having two mountain-shaped protrusions plays a role of locking the film by any one of the cutting operations of pressing the cover piece 5 at any position. Therefore, in the temporary fixing 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 cm.
cm, there is an advantage that it can be widely applied to boxes of various sizes.

FIG. 2B shows an example in which the shapes of the projections and the cutouts are complicated. In such a shape, it is considered that the dimensional 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 cover piece 5 is divided into two parts by a temporary fixing part Q and a stripping target part.
At the time of division, the stripping target portion is provided at three places in the longitudinal center portion and both end portions of the front plate 1 so that the area of the temporary fixing portion Q with respect to the whole is to be harmonized. ,
The dimensional position divisions of Z1 to Z3 (L1, L2) and Y1, Y2 can be considered as shown in FIG.

In general, a simple shape is sufficient, and FIG. 2C is a schematic view of a specific embodiment.
As the member used for the temporary fastening portion Q of the present invention, any of conventionally known members can be adopted, and among them, a case where a cross-linkable cured varnish is applied with an appropriate thickness and dried is preferable. Specifically, radical polymerization type, addition polymerization, preferably made easily form what it is in various forms of being a UV-crosslinkable cure varnish typified by cationic polymerization of the crosslinkable curable resin varnish or the like.

The paperboard used in the present invention has a thickness of 0.35 to 0.35.
In 1.5mm approximately cardboard typically has enough rigidity and strength that the wall thickness is high durable box obtained, since bending is difficult, usually a thickness 0.35～0.8Mm (basis weight 3
Relatively thinner paperboard ranging 10~550g / m ²⁾ is employed. The surface of the paperboard that is exposed on the surface of the box body, excluding the auxiliary side plate, the auxiliary side cover, the local joint, etc. Water-resistant printing varnish to increase water resistance,
Or, it was general that the entire surface was treated with a transparent varnish or the like. However, in contrast to this conventional product, the storage box of the present invention further improved the film withdrawing performance.
In a fold line portion between the varnish line and a varnish line, a so-called non-varnish-applied portion in which a printing varnish, a transparent varnish, or the like is not applied is formed in a band-like area having a width of about 1 to 5 mm above and below the fold line. It is desirable.

The cutting tool K used for the storage box of the present invention is shown in FIG.
May be used.
However, a cutting tool K having a V-shaped cutting edge at the tip of a cover piece 5 mounted on a box structure that is currently marketed and known as a so-called box type is applied to the storage box of the present invention. For example, the conventional problem that the finger is cut by the protruding V-shaped blade during the film picking (peeling) operation can be solved by providing the temporary fastening portion Q.

The wrap film referred to in the present invention is a generic 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. The effect is more remarkable and desirable.
