Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover structure design for use in document binding, and more particularly to the technical field in which a cover can be wrapped with a binding of a document. [Prior Art] Pressing, the binding of documents is a daily task in the office. How to complete it with the least cost and the shortest time has always been the goal pursued by office personnel. Using folders or folders to collect files, although it has the effect of binding, it is convenient to use, but folders or folders are more expensive, so the most common binding tools in the office still use staplers or clips, clips sheet. The stapler is most convenient to use and relatively inexpensive, but the document 100 bound by the stapler has the disadvantage that it is easy to stab the hand and easily scratch other documents because the stitch 20 of the binding is exposed. As shown in the first figure). Secondly, another method of binding a document is to use a clamp 3 〇 and a clamp 40 (as shown in the second figure). Although this type of use is simple, there are still several disadvantages similar to the stapler: 1. The clip 30 and the clip 40 are exposed on the outside of the document 100, which deteriorates the flatness of the appearance of the document 100, and the unfavorable document 1 The stacking of the crucibles; and if the material of the gripper strips 30 and the gripper strips 40 are iron sheets, there is a risk of cutting the hands. 2. If there is no additional matching clip and back cover used for the cover and the back cover 40, the document 100 is easily curled or wrinkled on the upper side and the lower side of the side binding. Second, the clamp strip 30 must be used with the clamped sheet 4, and the cost is high. Therefore, how to design a cover structure so that the document 1 can avoid the above disadvantages after binding becomes the main creative reason of the present invention. To avoid the above-mentioned shortcomings of using the stapled document (10) and causing the pin 2 to be exposed, it can be inspired by the traditional cover structure. As shown in the third figure, it is a type of clip with 3 clips and clips 4 The conventional cover structure which is common in use, the cover structure having the first binding portion 5 〇 and the first cover portion 60 'the first binding portion 5 (four) having a smaller width than the first cover portion 6 〇, and the area of the first cover portion 00 The size will be the same as the file to be bound: in the most common A4 file size, the area of the first cover part 6〇 is 21cm X 29.7cm, and in order to match the clip 3〇, clip 4 In the use of the cymbal, the cover structure is provided with two through holes 501 for the two ends of the nipple 30 to be used for the first binding portion 5'. Since the two through holes 501 on the first binding portion 5 are corresponding to the two through holes 1〇1 provided at the side of the document 1〇〇 binding, the two ends of the clamping strip 30 are respectively passed through the file. 100, the first binding portion 50, the last two ends are passed through the two through holes 4 (进入' and bent to the inner side of the clamping piece 40, and finally buckled by the buckle 402 on the clamping piece 4 While positioning, the task of clamping the document 1 to the first binding portion 50 is completed. It can be found from the third figure that the area of the first cover portion 6〇 is equivalent to the file 1〇〇, and the method is reversed. The first binding portion 5〇 and the clamping strip 30 and the clamping sheet 40 are covered under the first cover portion 6〇, and the attached document 100 is also covered, so that the first cover portion 60 becomes the document 100. The cover structure of the above-mentioned conventional cover structure is matched with the clamping strip 30 and the clamping piece 40, 1344423 t , and the binding tool (the clamping strip 30 and the clamping piece 4〇) is successfully wrapped on the inner side of the first cover portion 60. 'Let the clips 3 〇 and the clips 4 〇 will not be exposed on the binding cover. If you can put the binding tool ( The problem of the traditional stapler stitching 2〇 can be successfully solved by changing the binding method of the 〇 3〇, 掣 〇 4〇) into the stapler. However, the above-mentioned cover structure is not suitable for general use. The stapler is used for binding. Because the stapler is generally used for binding directly from the side of the document 100, the first cover portion is bound with the first binding portion 50 and the document 100 (as shown in the fourth figure). And the stitches 20 are exposed to the outer side of the first cover portion 60. Therefore, the inventors have inspired the above-described conventional cover structure, and if the user wants to make the first cover portion 60 not with the first binding portion 5 When the binding is combined with the same time, the direction of use of the stapler can be changed, that is, only the stacker is inserted from the other side of the document 100 so that the staple body can span the document 100. The body reaches the first binding portion 5, so that it can be used to bind only the first binding portion 50 and the document 100 without affecting the first cover portion 60 (such as the fifth figure). Shown) just to achieve this effect, the stapler The length of the body must be enough to span the body of the document. In general, the most common file size is 8 and 4 dimensions. The width of the file is 1cm. The size of the body is larger than that of a general-purpose stapler. At 10cm (four) 'cannot cross the document body at all, and bind the binding of the side of the document 1〇〇 to the first part of the cover 5 (as shown in the sixth figure). The length of the book body is not ^ to meet the user's binding needs across the file 5, for the ordering part, position? Only fine _ read the movement of the first ~ move to the position where the stapler can be bound, = (5) 5G position shift [Summary of the Invention] The knives can be solved. The first part: the present invention can be at least having a binding portion having a width smaller than the first one at the first end connected to the first seal, and苐一裴部

On the inner side of the seal of the 1st cover, the first cover part and the part of the first P 4 are the first cover part, and the first part of the cover is formed by a blank, and the heart material is covered by the cover part. side. When binding, the opening will face the binding cover ά] m Art machine can be extended into the first binding part and the first part, and the stapler's stitch will be covered by the first part. Live and successfully solve the problem of pin exposure. Secondly, a plurality of perforations are preset on the first binding part of the loading space, and when binding, the two ends of the clamping strip can be sequentially separated (4) and the corresponding perforation on the first binding part is - The binding part is turned on and off. At this time, since the first part 5 is covered and pressed by the first covering portion, the two pieces of the strip are refreshed.卩 will automatically affix to the first binding department, and no longer need the help of the smashing film, successfully achieve the purpose of reducing costs. Therefore, it is only necessary to additionally connect a first binding portion having a width smaller than the binding cover width on the inner side of the first cover portion, and form a binding space at a position where the first binding portion overlaps with the first cover portion, and the binding is performed. The opening of the space must face the binding side of the binding cover. In this way, when the document is bound, 1344423, regardless of whether the stapler or the clipper is used, can only bind the first binding unit to the binding, and does not set the cover, and is exposed at this time. The stitches on the third nipple or the two ends of the cool moving strip are cleverly covered by the first covering portion over the first binding portion to achieve the desired effect - that is, not only the stitches It is covered in the binding cover, and the end of the clamping strip _ end can also have a fixed function without the use of the missing sheet because of the pressure applied to the first predetermined portion by the first covering portion, and the utility model has the advantages of reducing the use cost. The advantages. In addition, if two the above-mentioned cover structures are used to bind the documents at the same time, • the problem of the stapler's pins being exposed can be completely solved, so that the exposed stitches or the ends of the clamped strips do not affect the appearance of the document due to the exposure. Flatness' or doubts about safety. According to the above description, however, the first covering portion and the first cracking portion are in an open state with each other, and the user may still contact the stitches or the clips due to the opening of the first covering portion, so The self-adhesive strip can be pre-set on the outer edge of the first binding portion facing the first covering portion, and the self-adhesive strip can also be disposed on the first covering portion. The side of the first binding portion allows the user to firmly adhere the first binding portion and the first covering portion with the self-adhesive strip after the binding is completed, so that the stitches exposed on the first binding portion are attached. Or clip the strip to get the best coating results. As mentioned above, the document lacks a complete cover and back cover, and there will be – the side cannot be properly protected. In order to improve this problem, it can be extended further on either side of the first cover of the creation. The second cover portion having the same area as the 7th face-face has a cover and a back cover structure, and at the same time, the structure can be between - and a plurality of book back fold lines: J binding seal = and the second cover portion The number of documents, corresponding to the folding of the book back of different sizes: in order to respond to the different two cover parts can be corresponding to the number of documents, the appropriate size == and the first to cover the file * good cover in the cover, ^ cover space Covered in the cladding space. The first binding portion can be carried by the second binding portion of the first binding portion, and the outer portion of the first binding portion can be extended to the outside of the first binding portion. One to several folding lines are arranged to make the first and second folding lines. Second: the joints of the crotch can be folded into multiple pieces to form a u-shaped binding part. 2 The binding side of the file can be completely covered by the first and second documents when binding. At the same time, the U-shaped hollow foot or the clamping strip originally formed on the second half portion is coated on the needles on the first and second binding portions.

Cracked in the space. Moreover, when the belt is used, the U formed by the kg can be folded by the first and second binding portions. 2. When the tool is a clip, the other type of material is used to integrally form the 11-type binding portion of the square. It is changed to a predetermined number of perforations on the ordering portion for the sake of "sweet & 4", and the U-shaped device is used for reinforcing the knot end portion of the u-shaped binding portion. The outer side of the binding part is further connected with an adhesive portion, and the stability is also stable. In the second strip, the adhesive layer can be self-adhered by the action of the self-adhesive strip, so that the adhesive portion is placed on the adhesive side. The edge of the whole /, the first cover part adheres to a more stable structural effect, of course, the read-point type binding part can obtain the adhesive part, the self-adhesive strip can also be set in the 1344442, the second cover part faces the second material part _. In the second cargo four binding department (the even number of bindings are called the side, and then the third and the outer outer sides are sequentially connected, and the outermost fourth seismic parts are first, second, and second. There is a self-adhesive strip on the station's sticking part, which makes it easy to use: \Four dressing parts form a W-shaped double V-shaped binding part, which is convenient for users to recognize different categories.

In the case of the document, when the document is loaded, the old piece is bound to the different binding parts of the binding part. After the binding is completed, the first, second, third and third sticking portions are adhered to the second cover portion, and the W-shaped binding portion formed on the fourth material portion is formed by the two stable-binding portions. The effect of the needle (4) depends on the fourth binding unit, the first and the first _-leer, and the second and fourth binding units are formed in the sealed space formed by the first and the second. The cover portion is covered with a blank cover _, and the adhesive portion ', the self-adhesive strip W (four) and the second cover portion face the opposite side of the fourth (four) predetermined portion.

~ Also, the 'adhesive part is not fixed. It is not allowed to use self-adhesive strips. Other equivalent functions can be used. For example, male and female buttons, or tongues, are respectively arranged on the positions of the opposite sides of the adhesive portion and the second cover portion. With the pick and so on. - Therefore, the main purpose of the present invention is to form a cover structure for binding a document, by forming a binding space in the &== 】 additional connection-width less than the bribe surface width (four) binding portion called the overlap with the binding cover, And the opening between the ^ ^ must be oriented toward the binding side of the binding cover, so that when the two documents are used, the small stapler can be used to easily bind the binding cover of the cover 9 1344423 to the document. The cover will not be ordered to set a plurality of perforations to facilitate the use of the ends of the clip bar 4=, and the pressure applied by the covering portion to the binding portion is the end of the clip bar above the binding portion. You don't have to use the effect of getting 岐. X, whether using a stapler or a folder to bind a document 'both materials to subtly cover the pins or sputum strips exposed on the I-stitch through the cover to cover the pins or clips The ¥ strips are all wrapped in the binding _©. _The cover part will completely cover the binding part to improve the traditional stapler binding file, because the stitches are exposed, which may cause injury, or because of the bulky size, the file stack is unfavorable, and the file itself is easy to be on the side. The disadvantage of curling or wrinkling on the upper and lower edges of the side binding, and the effect of beautifying the appearance of the document. [Embodiment] Now that the present inventors have a better understanding of the present invention, the following examples are described. First, as shown in the seventh figure, this is a preferred embodiment of the present invention. The cover 4 of the present invention has at least a first binding portion 51* - a first cover portion 6 and a width of the first binding portion 51 is smaller than The width of the first cover portion 61, and the first binding portion 51 is connected to the back side of the first cover portion 61, and the portion where the first cover portion 6! and the first binding portion 51 overlap is the first covering portion. (1) The first binding portion 51 and the first covering portion 611 form a mounting space V6' and the opening of the binding space V6 faces the binding side of the binding cover*. According to the above configuration, as shown in the eighth figure, the stapler can continue to be extended by the first binding portion 51 and the first covering portion 6: 10 1344423 in the binding space V6, and successfully The first binding portion & is shock-bonded to the side of the document, and at this time, the stitch ai of the stapler is covered by the first covering, and the solution is successfully solved by the present invention. problem. The ninth figure is a practical example in which the binding tool is changed from the stapler a to the clip bar b. The purlin b has two end portions b, and the first crotch portion 5 of the cover 4 is preset. The plurality of perforations 511 (in the figure, the two perforations are taken as an example). The two good bl of the clamp bar b are punched up and passed through the perforations 511 of the document 1 and the first binding portion 51, and then the first binding portion 51 is disposed. The upper surface is folded toward the front side, and then applied to the upper surface of the first binding portion 51. Since the pressure applied to the first binding portion 51 by the first covering portion 611 is such that both end portions bi of the gripping bar b are sandwiched - between the binding portion 51 and the first covering portion 611 (also as shown in the tenth figure). Thus, the inflammation is no longer required to be supplemented by the clamping piece, so that the end portions bl can be fixed. The tenth-picture is simultaneously used. Two embodiments, such as the cover 4 of the seventh figure, to bind the document 10, can completely solve the problem of the stapler's stitch exposure (here, only the binding tool is a stapler), because the second cover 4 is one. The top-down method encloses the document 10 in the middle of the 'stapler a' so that it can simultaneously protrude into the two cover sheets 4 formed by the first binding portion 51 and the first covering portion 611 In the binding space V6, it is achieved that only the side of the first binding portion 51 and the document 1 is bound together, and f affects the purpose of the first cover portion 61, while the first covering portion 611 is simultaneously The role of the role of the stitching a 1 originally exposed on the first binding portion 51 is hidden. Also as shown in the twelfth figure, the first binding portion 51 faces the side of the first covering portion 611 The self-adhesive strip 7 is provided in advance (in the figure, the example is 1344423). Of course, the self-adhesive strip 7 may also be disposed on the side of the first covering portion 611 facing the first binding portion 51 (not shown) It is drawn that the self-adhesive strip 7 can cause the first binding portion 51 to be attached to the first covering portion 611, so that the stitch a 1 exposed on the first binding portion 51 is completely covered by the first In the sealed space formed by the binding portion 51 and the first covering portion 611, the most effective coating effect is obtained. If the binding tool is changed to use the missing strip b, both end portions bl of the inflamed strip b can be similarly Covering the sealed space formed by the first binding portion μ and the first covering portion 611 to obtain the best coating effect (shown in the figure). ^ 3 is a further preferred embodiment of the present invention. The cover 4 has a first binding portion 5, a first cover portion 61 and a second cover portion 62. The second cover portion 62 extends from the second cover portion 62. The first surface portion 61 is provided with a side edge of the first binding portion 51, and the first front cover portion 6 has a second folding portion with a strip line 8' therebetween and is connected to the first side of the first cover portion 61. The portion of the binding portion 5 that overlaps the first cover portion 61 and the first binding portion 为 is the first covering portion 611 ', and a binding space V6 is formed between the first defining portion 51 and the first covering portion 6U. The opening of the binding space V6 is directed to the binding side of the cover 4. When the binding is performed according to the above configuration, the stapler (not shown in the drawing) can be extended into the first binding portion 51 and the first covering portion. The portion 611 is formed by the portion 611, and the first binding portion w and the side of the document 10 are successfully stapled together, and at this time, the stitch a 1 of the stapler is joined by a covering portion 611. Covering, at the same time, the document 10 will also be completely covered: the u-shaped covering space formed by the first and second cover parts 6 and 62 is covered by the invention. The problem. The difference between the fourteenth and tenth thirteenth steps is that three fold lines 8 are provided between the first and second cover portions 6b. The three fold lines 8 allow the first and second cover portions 61 of the cover 4 to be 62 forms a suitable U-shaped cladding space. The fifteenth diagram is a three-dimensional structure diagram of the thirteenth diagram (but the two-fold line is π)" and the sixteenth and fifteenth diagrams differ in that the second cover portion 62 extends from the first cover portion. 61 is disposed on the opposite side of the first binding portion 51. In fact, the first binding portion 51 may be disposed on the first cover portion 61.
