Description

The present invention relates to a saddle-stitched booklet for delivery (hereinafter referred to as "delivery booklet") having a novel opening system made of paper. More specifically, it relates to a delivery booklet that is suitably used when delivering catalogs, pamphlets, etc. containing a large amount of information advertising products and services by direct mail, etc. relates to a paper opening system provided with such delivery brochures.

In recent years, delivery booklets and delivery booklets that make it possible to mail and deliver advertising documents with a large amount of information such as product catalogs and pamphlets at low cost without putting them in envelopes are widely known. . In such a booklet, it is required that the contents be sealed with a belt-shaped outer paper and delivered to the delivery destination, and that the recipient who receives it can open it without using any tools. In such a paper-made opening system, the free end of the flap (one of the two-ply adhesive margins) adhered with a peelable adhesive is grasped with a finger, and the flap is peeled off from the surface of the member to be adhered. A system that uses such a peelable adhesive occupies the mainstream, and Patent Documents 1 and 2 disclose typical examples of a paper opening system that uses such a peelable adhesive.

Patent Document 1 describes the problem as follows: "[Problem] To obtain a booklet for delivery that does not need to be delivered in an envelope and can be delivered while holding a state in which reprinted paper such as leaflets or insert advertisements are sandwiched. As a solution, ``[Solution] An outer sheet 2 consisting of a front cover 5 and a back cover 6 and an inner sheet folded in half are saddle-stitched at the fold line F to form a booklet. An extension 7 formed by extending the fore edge 6E of the cover 6 is folded toward the front surface 5A of the front cover 5, and a notch 9 is formed in a part of the joint 8 of the front cover 5 that is in contact with the folded extension 7. The reprinted paper 11 inserted inside the front cover 5 is also provided with a joint portion 12 in contact with the extending portion 7, and the front cover 5 is provided with an opening 10 through which the address 13 written on the reprinted paper 11 is exposed. An adhesive layer 7A is provided on the surface of the extending portion 7 on the joint portion 8, 12 side, and the extending portion 7 and the joint portions 8, 12 are adhered to bind the fore edge of the booklet for delivery. Booklet 1 was constructed.”

In addition, Patent Document 2 describes the problem as follows: "[Problem] For example, direct mail can be delivered as it is without using an envelope, and moreover, the addressee can be included in the enclosed return postcard or fax paper. To provide a mailing booklet that eliminates the need to fill in one's own address and name and minimizes the trouble of the recipient." A sealing piece 2c continuous via a perforation C is provided on the free end side of the back cover 2b, and a separate piece of paper such as a postcard or facsimile paper on which the recipient's address A is written is provided between the cover 2a and the booklet body 5. - 特許庁6 is detachably attached, the sealing piece 2c is detachably attached to the cover 2a, and the address A is exposed from the window-shaped opening O formed in the cover 2a."

In the paper opening system common to the above, an adhesive that sticks releasably is used, and it is essential that this adhesive is releasable at the time of opening, but sufficient adhesion is required at the time of delivery. A balance needs to be struck between the need for force and the need for a small amount of adhesive force in order for the recipient to receive the shipping booklet to be able to open it without the use of any tools. However, there is a potential problem that manufacturing costs tend to be high due to the use of special adhesives.

In addition, when peeling the flap part adhered with the peelable adhesive from the surface of the member to be adhered, it is necessary to peel off the flap part formed of paper in a direction almost perpendicular to the surface of the member to be adhered. However, in the process of this peeling operation, the paper that constitutes the flap part tends to be stretched and partially curled, and the peeled flap part does not return to the flat state before opening, so it is unsightly after opening. A potential problem remains.

On the other hand, although it is not a package opening system that uses coated paper, which is generally used for delivery booklets, in the case of cardboard with a thickness of about 100 μm or more, the material is paper. As a common opening system for containers made of cardboard, instead of using a peelable adhesive, perforations are formed in advance at predetermined locations, and part of the cardboard of the container is torn along the perforations ( An opening system of the type "to the inside of the container" or "to the outside of the container" is generally used, and such opening systems are roughly divided into two types according to the difference in the opening operation method.

One of them is a zipper type having perforations, in which the free end of the belt-shaped area sandwiched between two parallel perforations or two opposing perforations is grasped with fingers and torn off. and the other is a flap portion that is continuous with the container-constituting main body portion via only one perforation (generally, one perforation that constitutes a substantially trapezoidal line), The free end of the tab portion of the flap portion, which has a tab portion with one free end formed on the upper portion of the trapezoidal shape, is grasped with a finger and pulled toward the outside of the container, or directed toward the inside of the container. It is of the type in which it is torn along the trapezoidal perforations while pushing it in.

As a representative example of the former, there is Patent Document 3, in which the problem is described as "[Problem] to provide a booklet-like mailing matter consisting of a single sheet capable of providing a large amount of information." As a solution (that is, an invention), "[Solution] A booklet-like sending matter made by folding one sheet of paper, the paper has a left-right folding line that divides the paper into upper and lower halves, A vertical folding line is formed to divide the paper into three or more sections on the left and right sides, and the sheet is divided into six or more sections. A notch is provided in the part where the upper and lower compartments meet, and a cut is made in either one of the left and right ends of the upper side or one of the left and right ends of the lower side outward in the left and right direction. A glue margin flap is extended, and the glue margin flap is adhered to a section in the left-right direction adjacent to the section in which the glue margin flap is extended."

However, in the former case, it is necessary to put the torn strips in a trash can so that they are not scattered around. It becomes an unsightly condition, and it is easy to contribute to the environmental load even if it is small.

As a representative example of the latter, US Pat. Patent Document 3 summarizes it as follows: "[Summary] An opening system for a container 10 includes an end fold 18A that extends over the opening of the container 10 and a sealing fold 16A that covers the end fold 18A. The end fold 18A includes an open area 38 and the sealed fold includes perforation patterns 34, 36. The perforation patterns 34, 36 include a central portion extending over the open area 38. A first line of perforation 34 and a second line of perforation 36 extending from the first line of perforation 34 to one edge of the sealing fold 16A. It is configured to tear with a lower force than."

However, in the latter case, especially when applied to a saddle-stitched booklet for delivery or mailing as contemplated in the present invention, the amount of space other than the planar space occupied by the paper opening system that seals the outside of the booklet in a band-like manner is Since it is necessary to print some information on the flat space (the flat space provided by the outer strip of paper), the potential problem remains that the printing space must be small.

In addition, the paper to which such an opening system using perforations can be applied is generally thick paper or special coated paper, which inevitably increases the manufacturing cost. In addition, as the paper to be used, thick special paper that is unsuitable for wrapping paper for mail is required. In the case of the outer paper of the booklet, it is necessary to reduce the weight of the entire booklet for delivery by making the thickness of the entire booklet including the outer paper as thin as possible. In the case of packaging using thin paper with a thickness of about 140 μm, there is a problem that an opening system using perforations is generally unsuitable. The system seems to be non-existent.

The main effects (that is, the problems solved by the invention) claimed in the patent documents disclosing the above representative inventions are:
1) It is possible to mail or deliver a paper medium containing a large amount of information. 2) It is possible to reduce costs because envelopes are not used. There are surprisingly few prior arts that deal with the problems only on the side of the manufacturer and intend to solve the problems potentially faced by such delivery booklets and recipients such as general customers who receive the delivery booklets. .

As a scene where problems related to such delivery booklets and delivery booklets are inherent,
(1) manufacturing stage; (2) transportation stage; (3) stage of posting the delivery in a mailbox or the like; (4) stage of opening by the recipient who received the delivery; Although it is assumed that the problems encountered in the stages (1) to (3) among these are almost all solved by the inventions disclosed in the above various prior patent documents, (4) Focusing on the problems that are expected to be encountered in stages (5), it can be understood that the following potential problems exist.

(potential problem)
1) In the case of a paper opening system that uses a peelable adhesive, when the adhesive margin flap is pulled from the main body, the fibers that make up the paper on the flap stretch and cannot return to its original flat state, resulting in opening. The state afterward is unsightly.
2) In the case of a zipper-type paper opening system with perforations, it is necessary to put the torn belt-shaped member in a trash can, etc., so that it does not scatter around. If they are not there, they remain scattered around and are unsightly, and they tend to contribute to the environmental load, even though they are small. In addition, since the perforations that make up the zipper are inevitably exposed, part of the perforations may break when printing on the outside of the delivery booklet or when an unexpected external force is applied during delivery. is concerned.
3) In the case of paper opening systems that tear along the lines of trapezoidal perforations, especially when applied to saddle-stitched booklets for delivery or mailing as contemplated in the present invention, such delivery From the point of view of the original function required of a booklet, that is, the function of posting a large amount of information, a flat space other than the flat space occupied by the paper opening system that seals the outside of the booklet in a strip shape The flat space provided by the outer paper) is also required to contain or print a large amount of information, which inevitably results in a smaller space for printing.
4) In the case of an opening system that uses a trapezoidal perforation to tear, if the paper is thin, the paper tends to tear at the base of the tab rather than at the perforations. Inevitably, the size must be increased, which increases the manufacturing cost.
5) In addition, when the trapezoidal perforation type opening system is applied to the saddle-stitched booklet for delivery or mailing contemplated in the present invention, the size and weight imposed on the delivery or mailing From the point of view of the restriction of , it is necessary to reduce the thickness of the strip of paper that seals the outside of the booklet as much as possible.
6) Whether or not a recipient who receives a booklet with a large amount of information printed on it will actually open the cover or outer paper of the booklet is unknown to the sender. It is hard to say that the paper-made opening system has been devised. In other words, there is still insufficient ingenuity to arouse the recipient's urge to open the booklet when receiving a similar booklet.

Therefore, as a result of earnest research, the inventor succeeded in devising a method capable of solving all of the above problems at once, and completed the present invention.
That is, the first invention is
A booklet for delivery in which the main body of the booklet is saddle-stitched together with the outer cover,
The front surface portion of the outer cover has an extension with a tab extending through the perforation line, and the extension with the tab is a tab, and at least a part of the contour line a tab having a free end defined by a punched line or continuous score line provided along the tab;
The four front surfaces of the outer cover have extensions for folding that extend through the fold lines,
The extension for folding is overlapped with and adhered to the extension with tab,
When unsealing, the free end of the tab provided on the tab-attached extension is held and pulled so that the tab-attached extension remains adhered to the folding extension. , and a booklet for delivery, characterized in that the booklet is tearable along the perforation line.

A second invention is, in the first invention,
The extension part for folding is overlapped and adhered to the extension part with the tab part so that the perforation line is not exposed.

A third invention is, in the first invention or the second invention,
The tab portion is formed integrally with the extension portion with the tab portion, and the free end portion extends toward the front side of the outer cover sheet.

A fourth invention is, in any one of the first to third inventions,
The perforation lines are divided into two perforation lines that are continuous with the perforation line or the continuous cut line of the tab portion, respectively, and are respectively connected to the front surface portion of the outer cover and the extension portion with the tab portion. It is characterized by constructing a straight line parallel to the partition line between them.

A fifth invention is the third or fourth invention,
A part or the whole of the tab portion provided on the extension portion with the tab portion is positioned further than the free end of the extension portion for folding superimposed on the extension portion with the tab portion. It is characterized by extending to the side.

According to the present invention, the above-described (1) manufacturing step; (2) printing on the outer cover of the delivery booklet; (3) transportation step; 5) The step of opening the delivery booklet by the recipient;

Furthermore, (7) in the case of the conventional gluing opening system, when the longitudinal length of the gluing flap portion is about 29.6 cm, when an ordinary person tries to open it normally, it is completely It takes about 5 to 6 seconds to open, but in the case of the opening system according to the present invention, it takes about 1 to 1.5 seconds for the same size. In addition, the act of "breaking" a new thing, which is one of the acts that humans feel pleasant, is accompanied by the fact that the paper used in the paper opening system according to the present invention is thicker than a predetermined thickness. In the case of having , it is possible to enjoy the pleasant feeling of "making a sound when breaking" along the perforation line, so it is possible to provide both speed and pleasure of opening, and an improvement in the opening rate can be expected. A remarkable effect beyond the expected range is also exhibited.

FIG. 4 is a front view A and a back view B schematically showing a sealed state with a band-shaped outer cover sheet used in the present invention. 1 is a perspective view schematically showing a state in which a delivery booklet according to the present invention is opened at a predetermined location (where an opening system is installed); FIG. FIG. 4 is a process diagram schematically showing a manufacturing process of a delivery booklet according to the present invention;

The delivery booklet according to the present invention will be described in detail below. First, the manufacturing process of the delivery booklet according to the present invention will be described below with reference to the drawings.
(manufacturing process)
The paper opening system according to the present invention and the saddle-stitched delivery booklet having the paper opening system can be manufactured by the following procedure.

Step 1:
A rectangular sheet of paper 100, indicated by reference numeral 100 in FIG. 1, is prepared by cutting it to size in a known manner from a paper roll. Alternatively, get a piece of paper already cut to size. The figure is a schematic diagram and does not represent the actual size, and a rectangular sheet of paper is shown there. Any shape of paper can be used as long as it does not deviate from the scope of the achievable components, but the delivery booklet according to the present invention is also intended to be used as first class mail as stipulated by the Postal Law. Therefore, it is preferable that the size and shape be such that it can be sent as standard-sized mail as specified by Japan Post Co., Ltd.

As for the type of paper to be used, so-called coated paper is preferable from the viewpoint of water resistance at the time of delivery, but it is not necessarily limited to this. Any kind of paper can be suitably used as long as it can be used. In addition, the thickness of the paper is preferably about 140 μm like ordinary type coated paper, but it is not necessarily limited to this, as long as it does not deviate from the scope of the constituent elements that can achieve the object of the present invention. Any thickness of paper can be used.

FIG. 2 shows a mode in which the outer cover sheet is flattened out after the delivery booklet according to the present invention is manufactured using the rectangular paper schematically illustrated in FIG. 1 as the outer cover sheet. The one-dot chain line indicated by reference number 125 in the approximate center of FIG. 2 is for the purpose of helping understanding of the description of the manufacturing process described later, and indicates the crease line that will be the mountain fold line for convenience. It does not show the accompanying line. Also, the dotted line indicated by reference number 115 on the left edge of the rectangular paper schematically illustrated in FIG. It shows lines for convenience and does not show any actual lines, but depending on the thickness of the rectangular paper used for the outer cover sheet, perforations with actual It goes without saying that it is also preferable to make a non-cut line.

Step 2:
As described above, the fold line indicated by reference number 115 in FIG. 1 or FIG. 2 does not necessarily have to be a perforation line. In this case, the perforation line A is formed by a known method using a micro sewing machine or the like so that the size and pitch of the non-cuts are each predetermined values. to form a belt-like extension A (corresponding to an extension for folding, which will be described later) indicated by reference number 110 . In this case, the size and pitch of the cuts and non-cuts that make up the perforation line A are preferably 0.2 mm to 0.5 mm wide blades at intervals of 0.1 mm to 0.2 mm, more preferably, The sizes and pitch values of cuts and non-cuts obtained by a micromachine having blades of 0.35 mm width at intervals of 0.15 mm, but are not necessarily limited thereto, and the object of the present invention can be achieved. Any kerf and non-kerf size and pitch values can be used without departing from the range. The purpose of forming this perforation line A is to form a sharp folding line when the strip-shaped extension part A is folded by a folding machine along the line formed by this perforation line A. However, when printing on the outer cover of the delivery booklet according to the present invention, the size and pitch of cuts and non-cuts should be such that the paper is not torn when folded during delivery or mailing. It goes without saying that it must be configured to be a value. From this point of view, when the thickness of the paper used for the outer cover sheet must be reduced, it is preferable to form the perforation line A simply as a folding line without providing the perforation line A. Any shape can be used for the shape of the cut as long as the object of the present invention can be achieved. can be linear. In addition, it is preferable that the line of the perforation line A is parallel to the free end of the strip-shaped extension part A indicated by reference number 110, but as long as the object of the present invention is not deviated, Both perforated and non-perforated embodiments can be suitably used. In the following description, when the crease indicated by reference number 115 in FIG. 1 or FIG. shall be read as "folding line A".

Step 3:
Lines of perforation B (consisting of cuts and non-cuts) indicated respectively by reference numerals 135A and 135B in FIG. By forming by a known method (e.g., punching method) so that the distance between adjacent cuts) has a predetermined value, a band-shaped extension B (tab portion described later) indicated by reference number 130 is formed. (corresponding to the extension part) is formed. In this case, the size and pitch of the cuts and non-cuts that constitute the perforation lines 135A and 135B respectively (the interval between the end of one dogleg-shaped cut and the end of the opposite dogleg-shaped cut) Preferably, the length of one side of the dogleg is about 5 mm to 15 mm, the length of the other side is about 2 mm to 4 mm, the radius of curvature of the deflection portion is 4 mm, and the pitch (width of the non-cut portion) is 1 mm, more preferably, a doglegged cut having a length of one side of the doglegged character of 10mm, a length of the other side of 3mm, and a radius of curvature of the deflection portion of 4mm; It is the size and pitch value of dogleg-shaped cuts and non-cuts obtained by a zipper type perforation line forming device equipped with a punching blade having a size and pitch value such that the width of the non-cuts between the cuts is 1 mm. However, it is not necessarily limited to this, and any cut and non-cut size and pitch values may be used without departing from the scope of achieving the objectives of the present invention. The purpose of forming the perforation lines 135A and 135B is that one end of the belt-shaped extending portion B (the back cover portion providing the front side 4) is opened when the recipient who receives the delivery booklet according to the present invention opens it. (Hereinafter referred to as "the front four surface portion"), the tab portion 140 (see FIG. 4) provided on the side is gripped with fingers to provide the front surface together with the belt-shaped extension B (hereinafter referred to as the front side cover portion). By pulling in the out-of-plane direction of the "front side part"), the belt-shaped cover sheet can be broken and opened along the lines formed by the perforations 135A and 135B. and non-cut size and pitch values, while ensuring that neither of these perforation lines 135A and 135B are torn during printing on the outer cover of the shipping booklet according to the present invention or during its shipping. When opened by a person, the strip-shaped cover sheet can be easily torn along the lines of the perforations 135A and 135B by gripping and pulling the tab portion 140 integrally provided with the strip-shaped extension portion B with fingers. It goes without saying that the size and pitch values should be such that they have a sufficient strength.

Step 4:
A tab indicated at 140 in FIG. 1 or FIG. 2 is integrally formed with a strip extension B indicated at 130 in a known manner, i.e. from the strip B. Extend beyond one end. One of the features of the present invention is that the surface of the tab portion 140, the surface of the front surface portion (reference number 120B), and the surface of the strip-shaped extension portion B are positioned on the same plane. However, this feature is not an essential component, and it goes without saying that any member can be suitably used as long as it exhibits substantially the same function as the tab portion of the present invention. In this case, the base of the tab portion 140, that is, the contour line of the tab portion 140, is connected to the line formed by the perforation line B indicated by the reference number 135A or 135B with a curve having a radius of curvature R1. A cutting line (continuous cut) (indicated by a solid line in the figure) is formed by a known method along the contour line of the tab portion 140 from the root point to the opposite other root point. to form a free end on a portion of the tab portion 140 . The purpose of providing this tab portion 140 is to fold the rectangular paper 100 along the line 115 of the perforation line A as shown in FIG. Since the part side extends from the belt-shaped extension part B (reference number 110) after being folded, when the recipient opens the delivery booklet according to the present invention, the extension part can be grasped with a finger. Grasping and pulling is to cause the end of the strip-like extension B to break along perforation lines indicated respectively by reference numerals 135A and 135B. Therefore, any shape and size may be used as long as the object can be achieved.

Also, the tab portion 140 is preferably integrally formed with the strip-shaped extension B (reference number 130) (in terms of minimizing the manufacturing process steps), but the objectives of the present invention are achieved. As long as it does not depart from the scope of the components, it does not necessarily have to be integrally formed. The back side of the strip-shaped extension A indicated by reference number 110 when viewed from the side, or the strip-shaped extension B indicated by reference number 130 (FIG. 1 or FIG. 2) which is hidden underneath. It may also be affixed to the front side) with an adhesive.

Further, when opening the delivery booklet according to the present invention, the tip of the tab portion 140 (that is, the portion extending from the strip-shaped extension portion B (reference number 110)) is grasped and pulled with fingers, When tearing the edge of strip B along perforation lines respectively indicated by reference numerals 135A and 135B, the area near the root of this tab portion 140 (i.e., the contour line of the tab portion 140) is broken. However, since the tearing stress must be concentrated in the area near the root connected to the line formed by the perforation line B indicated by reference number 135A or 135B), in order to avoid such stress concentration as much as possible, the root portion is configured in a curved shape with a curvature radius R1 having a center of curvature on the side of the front surface portion (reference number 120B). From this point of view, the radius of curvature R1 is preferably 5 mm to 9 mm, more preferably 6 mm. In this case, the central angle of the arc drawn by the curve with the radius of curvature R1 is preferably 60 degrees to 90 degrees, more preferably 90 degrees. The purpose of curving the contour line of the base of the tab portion 140 in this way is to avoid the concentration of tearing stress that occurs at that portion when opening the belt-shaped cover sheet of the delivery booklet according to the present invention, and to Sometimes, the tab portion 140 and the belt-shaped extension portion B act integrally to make it easier to open the belt-shaped cover sheet. are not necessarily limited to these.

Further, the contour lines near both ends of the head portion of the tab portion 140 are formed in a curved shape with a radius of curvature R2 having the center of curvature on the side of the belt-shaped extension portion B. The reason for this is that the tab portion 140 When gripping the tip portion (that is, the portion extending from the strip-shaped extension B (reference number 110)) with the fingers, the strip-shaped extension A (reference number 110) in the state shown in FIG. ) is slightly bent toward the back side of the sheet of FIG. 140 is proportional to the square of the thickness of 140), the tip of the tab portion 140 is lifted from the height of the surface of the front side portion (equivalent to the thickness of the paper at that portion), and this lift is used. This is to facilitate gripping the tab portion 140 with fingers. From this point of view, the radius of curvature R2 is preferably 5 mm to 9 mm, more preferably 6 mm. In addition, in order to make the contour line near both ends of the tip portion of the tab portion 140 curved with a radius of curvature R2, the tab portion 140 In the vicinity of the root of the concave recess (recess) formed in a similar shape to the contour near both ends of the delivery booklet according to the present invention Also included is the prevention of tearing and damage to the cover strip due to the occurrence of unexpected tear stress concentrations during printing on the outer cover sheet or during its delivery. Therefore, any value can be suitably used for the radius of curvature R2 as long as it does not deviate from the scope of the components capable of achieving the object of the present invention in the above-described viewpoints. From this point of view, the contour lines in the vicinity of both ends of the head portion of the tab portion 140 do not necessarily have to be curved lines, and contour lines formed by intersecting straight lines can be suitably applied.

From the viewpoint of the function required of the tab portion 140, when the tab portion 140 is integrally formed with the band-shaped extension portion B in the manner described above, the thickness of the paper at the portion of the tab portion 140 is There appears to be a preferred range of values for out-of-plane bending stiffness of the sheath, and that range for thickness is preferably on the order of 50 μm to 200 μm, more preferably 140 μm. However, on the premise that it does not affect the scope of rights of the present invention, if paper with a thickness within this range is used for the strip-shaped cover sheet according to the present invention, it will not be easy to open it as described later. From the viewpoint of the thickness of the cover sheet, and from the viewpoint of ensuring that the band-shaped cover sheet is properly torn along the perforations 135A and 135B, which will be described later, at the time of opening, some function From this point of view, it is considered necessary to suitably select the size and pitch of the cuts and non-cuts forming the perforation line B described above. In any case, the thickness referred to here is considered to be affected by the combination with other constituent elements in particular. It is not limited to the above range.

As for the manufacturing process of the rectangular paper shown in FIG. It goes without saying that similar results can be obtained by cutting into rectangular sheets of paper.

Step 5:
When the above steps 1 to 4 are completed, the belt-shaped extension part A (reference number 110), the front 4 surface part (reference number 120A), the front 1 surface part (reference number 120B) (the front 1 surface part and the front 4 surface part are mountain folds The rectangular paper 100 having the strip-like extension B (reference number 130) is obtained, since the elements as a continuum are indicated by reference number 120, since they are continuous via the folding line 125 of the formula. be done. In this case, the width of the belt-shaped extension A (the width along the longitudinal direction of the rectangular paper 100) is greater than the width of the belt-shaped extension B (reference number 1130) (the width along the longitudinal direction of the rectangular paper 100). larger and smaller than the width between the outline of the distal end of the tab portion 140 and the free end of the strip-shaped extension B (reference numeral 130) (i.e., the end opposite the tab portion 140). requested. This is done by folding the rectangular paper 100 along the line 115 of the perforation line A as shown in FIG. 3, and as schematically shown in FIG. By extending from the strip-shaped extension part A (reference number 110) to the front side part side, when the recipient who received the delivery booklet according to the present invention opens it, this extension part can be held with a finger This is so that it can be grasped. Therefore, the width of the belt-shaped extension A in the longitudinal direction of the rectangular paper, the width of the belt-shaped extension B, the extension size of the tab portion, and the width of the tab portion in the direction orthogonal to the longitudinal direction of the rectangular paper are respectively ,Preferably,
Width of band-shaped extension A: 28 mm to 35 mm
Width of band-shaped extension B: 23 mm to 27 mm
Extension size of the tab part (length from the position of the base of the tab part to the position of the head): Minimum 10 mm
Width of tab part: 20 mm to 30 mm
and more preferably
