Description

本发明涉及纸件办公用品,尤其是具有强化的侧面、拐角和边缘的可伸缩文件夹,用以使卷宗更为牢固和耐用。 The present invention relates to paper office supplies, in particular with reinforced sides, corners and edges of expandable folders, files for causing more solid and durable.

可伸缩文件夹是现代化办公或商业的必备工具,并普遍使用于家庭和学校。 Expandable folder is an indispensable tool of modern office or business, and widely used in homes and schools. 这种文件夹通常由矩形前板和后板组成,沿着底部和侧面有“Z”字形折层,一般称之为联接片,它使得文件夹能够由前向后展开。 This folder is usually of a rectangular front and rear panels, along the bottom and sides with a "Z" shaped folds, generally known as the gusset, so that the folder can be deployed from front to back. 这种文件夹在压紧状态下运输和贮存。 Such folders in the compressed state transportation and storage. 当投入使用时,随着文件夹装满文件、纸张或其它物品,联接片使得该夹子逐渐伸展开。 When put into use, is filled with file folders, papers or other items, so that the clip gusset gradually extended.

一种典型的五片结构为很多种可伸缩文件所采用。 A typical structure is a five files are used more scalable. 这种结构包括第一前板和后板以及与之相连的侧面和底部联接片的组合,还有分别与第一前板和后板相连的第二前板和后板。 This structure comprises a first front and rear panels and combinations of side and bottom gusset attached thereto, and second front and rear panels are connected to the first front plate and the rear plate. 通常,联接片的终端固定在第一与第二板件之间。 Typically, the coupling terminal is fixed between the first plate and the second plate member.

这种可伸缩文件夹通常装满(或过量装满)文件,直到联接片完全展开,再也放不进去其它的文件。 Such expandable folder typically filled (or overfilled) file, until the fully expanded gusset, could not fit into other documents. 不过,以这种方式填充可伸缩文件夹通常会因为在某些转折部位或高张力部位撕裂而导致文件夹过早损坏。 However, in such a way to fill the expandable folder normally because in some parts of inflection points or tear high tension lead to premature failure of the folder. 这些转折部位最常见于联接片与前板和后板之间的交接点、文件夹的拐角处、联接片的顶边部位以及联接片本身。 The most common inflection points of crossing points between the coupling piece and the front and rear panel, the corners of the folder, the top edge of the gusset portion and the gusset itself.

充分展开的文件夹通常在联接片与前板和后板之间的交换点处撕裂,因为当这些展开的文件夹被发现装有特定的文件时,查阅者通常会进一步展开该文件夹以便查阅并取出存放在里面的文件。 Fully expanded folders usually tear at the switching point between the coupling piece and the front plate and the rear plate, because when these expanded folders are found with a particular file, usually Now further expand the folder to Check and remove the files stored inside. 另外,当取出的文件必须要放回到文件夹里时,查阅者将再次展开文件夹以制造一个空间,以便能顺利地将文件放进去。 In addition, when taken out of the file must be placed back in the folder, access will expand the folders again in order to create a space, in order to smoothly put in the file. 然而,由于联接片已经充分展开,让文件夹进一步展开的唯一办法就是使文件夹在联接片与前板和后板的交接点处撕裂。 However, since the coupling piece has been fully developed, so the only way to further expand the folder so that the folder is at the intersection of the gusset with the front and rear panels of the tear.

充分展开的文件夹还相对较重,并且这一重量会以各种方式造成文件夹损坏。 Fully expanded folder also relatively heavy, and the weight will cause damage to the folders in various ways. 例如,通常仅通过前板和后板将文件夹拾起,这样会导致该板件整个从联接片上拉下来。 For example, typically the front and rear panels only pick up the folder, such causes the entire panel from the pull-down gusset. 此外,当充分展开的文件夹被反复放置到写字台或桌面上时,文件夹的拐角、侧面和底部在桌面上的摩擦,会导致文件夹在这些部位磨损或损坏。 Further, when fully expanded folder is repeatedly placed on a desk or table, the corners of the folder, the side and bottom of the friction on the desktop, folder will cause wear or damage at these sites. 这种磨损或损坏有损于文件夹应有的整齐外观,进一步削弱文件夹,并导致夹在里面的小物品散落。 This wear or damage detrimental to the proper folder neat appearance, further weakening the folder, and lead clip on the inside of the small items scattered. 当满载的文件夹掉落时,文件夹会沿着联接片与前板或后板的接缝处分裂,使文件夹或里面的内装物散落在撞击点周围。 When a full folder is dropped, the folder will split along the seam of the gusset with the front plate or the back plate, so that the folder contents inside or scattered around the impact point.

可伸缩文件夹通常还存放在架子上,其正面和背面与架子的长度垂直。 Expandable folder usually stored on shelves, the vertical length of the front and back surface of the rack. 当取出这些文件夹时,一般将手指放在联接片的上部边缘,以便将文件夹从架上摘下来。 When these folders are removed, generally finger on the upper edge of the gusset, so that the folders come off the shelf. 然而,由于充分展开的文件夹比较重,以这种方式拉出文件夹通常会导致联接片与前板和后板分离。 However, since the fully expanded folder is relatively heavy, the folder in this manner often leads drawn out of the gusset with the front and rear panels separated. 此外,通常用手指从联接片的同一部位一次又一次地拉取文件夹,长此下去,污物和汗水会聚集在联接片上,从而损坏并削弱联接片,并导致在取出文件夹时联接片意外撕裂。 Further, usually from the same finger portion of the gusset over and over again pulling the folder, the long run, dirt and sweat will accumulate on the gusset, the gusset to damage and weaken, and when removed results in the folder gusset unexpected tear.

这种文件夹在使用时会变得潮湿,在从一个地方转运到另一个地方时由于淋雨或雪而变湿,或是当水或饮料(象咖啡、茶或苏打水)意外地溅洒在它上面时而变湿,或是在存放时因为空气中的水分而变湿。 This folder will become wet during use, when transferring from one place to another due to rain or snow becomes wet or when water or beverages (such as coffee, tea or soda) accidentally spilled wet on it from time to time, or upon storage because moisture in the air becomes wet. 当这种文件夹变潮或变湿后,他们会明显弱化并很容易撕裂。 When this folder becomes damp or wet, they will be significantly weakened and tear easily. 此外,潮湿的文件夹当变干时会发生变形、弱化和损坏,而且,在这种情况下也非常容易撕裂。 Further, when the wet folders become deformed when dry, weaken and damage, and, in this case also very easy to tear.

这种文件夹一般是通过附着于前板或后板上的压敏粘着标签来识别的。 This folder is identified generally by the pressure-sensitive adhesive label attached to the front plate or the rear plate. 然而,当需要除去这些标签时,由于不能将标签上的粘着物与板上的纤维分开,因而会使文件夹毁形。 However, when the need to remove these labels, since the adhesive material can not be on the label separately from the fiber board, and thus cause disfigurement folder. 这样,这些文件夹往往仅因为不再具备整齐的外观而报废。 In this way, these folders are often only because they no longer have a neat appearance and scrapped.

本申请人认识到了上述问题,并确信需要一种解决了上述问题的可伸缩的文件夹。 The Applicant has recognized these problems and are confident that these problems need a solution scalable folders. 具体来说,需要这样一种耐用的超强度可伸缩的文件夹,即:在它装载至极限量时不会损坏,能防液体浸湿,并能保持整齐、坚固的外观。 In particular, a need for a super-strength durable scalable folder, namely: it is not damaged when loaded extremely limited, can prevent liquid wet, and to maintain a neat, sturdy appearance.

参见附图,尤其是图1和图2,这里表示了本发明可伸缩文件夹10的第一个实施例。 Referring to the drawings, in particular FIGS. 1 and 2, there is shown the present invention the expandable folder 10 of the first embodiment. 文件夹10包括一个前板11、一个后板12、开口的顶部13以及前板11与后板12之间的“Z”形折叠的联接片14形式的连接件。 Folder 10 comprises a front panel 11, a rear plate 12, "Z" 14 in the form of a gusset-folded between the connecting member 12, the top plate 13 and a front plate 11 and the rear opening. 联接片14构成文件夹10的侧面15的一部分和整个底部16。 Gusset 14 constitutes a part of the folder 10 and the side surface 15 of the entire bottom 16.

前板11包括从一卷厚纸板或卡片纸(例如红纸革、红绳浆纸或马尼拉纸)35上裁切或冲压而成的内层11a和外层11b。 The front plate 11 includes a cut or stamped from a roll 35 of cardboard or card (e.g. leather red paper, red rope, or manila APP) inner 11a and outer 11b. 内层11a和外层11b通过粘接、冲压或以其它方式相互连在一起,制成前板11。 An inner layer 11a and outer layer 11b by gluing, stamping, or otherwise attached to each other, the front plate 11 is made. 类似地,后板12包括由一卷厚纸板或卡片纸(例如红纸革、红绳浆纸或马尼拉纸)35裁切或冲压而成的内层12a和外层12b。 Similarly, the rear plate 12 comprises a roll of cardboard or card (e.g. leather red paper, red rope, or manila APP) 35 formed by cutting or stamping the inner 12a and outer 12b. 内层12a和外层12b也是通过粘接、冲压或诸如此类的方式相互连在一起,制成后板12。 12a is an inner layer and an outer layer 12b by gluing, stamping, or the like manner connected to each other, rear plate 12 is made. 此外,还可将前板和后板的材料自身折叠并粘在一起,以制成外部和内部板件。 Further, the material may also be front and rear panels folded upon itself and bonded together to form outer and inner panels. 通常的安排是,将马尼拉纸用作后板12的内层12a,将红纸革用于其它三个部件,不过,可以根据文件夹10的预定用途采用任何一种组合形式。 Arrangement is a general, the inner layer 12a as manila board 12, the other three components for leather red paper, however, any combination may be employed in accordance with the intended use of the folder 10.

然而,在由一卷纸板35冲压外层11b、12b之前,最好用丙烯酸涂料27对纸板35的一面进行防液体处理。 However, before the press roll 35 of cardboard the outer 11b, 12b, preferably with a liquid-proof treatment for one surface of the acrylic board 35 of the coating 27 pairs. 纸板35被处理过的一面将作为外层11b、12b的外表面,而涂料27将起到防止水分渗入文件夹10的作用。 The treated web 35 as the outer face 11b, 12b of the outer surface, and the coating 27 will play the role of preventing the penetration of moisture into the folder 10. 另外,涂料27还使得在文件夹10上贴标签、撕标签变得容易,它通过避免标签上的粘接剂与文件夹10的表面发生实际接触而防止因反复贴标签、撕标签所导致的文件夹10毁形。 Further, the coating 27 such that the folder 10 also attach a label, the label is easy to tear, to prevent actual contact file due to repeated labeling, the label tear caused sandwiched by avoiding its occurrence surface 10 with the adhesive on the label file folder 10 disfigurement. 涂料27最好是从Newport的Roymal有限公司(New Hampshire)购买的苯乙烯化的丙烯酸水基乳液36,它通过苯胺印刷工艺来施用,正如这里所讨论的。 Preferably the coating 27 is from Newport, Roymal Limited (New Hampshire) purchased styrenated acrylic water based emulsion 36, it is applied by the flexographic printing process, as discussed herein.

如图3、4、5和6所示,联接片14由一张层压的平板纸19制成,用已知的方法将平板纸19反复折叠,使其具有象手风琴那样的伸展能力,以使文件夹10在装入要存放的物件时能逐步展开。 As shown in FIG. 4, 5 and 6, the coupling of a laminated sheet 14 made of flat paper 19, by a known method repeatedly folded flat paper 19, so as to have the ability to stretch like an accordion, to the folder 10 can be gradually carried out when loading items to be stored. 纸制联接片14具有足以沿文件夹10的侧边15和底部16延伸的长度,而纸的宽度则根据所需文件夹的展开厚度来选择。 Paper sheet 14 having a coupling 15 and a length sufficient to extend along the bottom portion 16 side of the file folder 10, and the width of the paper is expanded according to the desired thickness of the file folder is selected. 联接片14以终端17、18结束,其折叠大小接近联接片折叠的尺寸。 Coupled to terminal 17, 18 of the end plate 14, which is close to the size of the folded gusset folded dimensions. 或者,该终端折页17、18可以至少是联接片14内部折页28的两倍宽,或是至少是7/8英寸宽,无论如何都比较宽。 Alternatively, the terminal folds 17, 18 may be an internal gusset 14 at least twice as wide as 28 fold, or at least 7/8 inch wide, in any case relatively wide. 最好利用终端折页17、18的展开宽度,来增加联接片14与板件11、12的接触表面积,从而加强二者之间的连接。 Preferably by developed width terminal folds 17, 18 to increase the contact surface area 14 and the gusset plate member 11, 12, thus strengthening connection therebetween. 不过,下面这样的联接片也可用于某些文件夹,即:其侧面部分15的终端折页宽度加倍,而其底部16的终端折页为标准宽度,即与内部的折页宽度相等。 However, following such coupling pieces can also be used in some folder, namely: the width of which side of the terminal flap portion 15 is doubled, while the bottom end 16 of the folding of standard width, i.e., inner width equal to folding. 这是因为联接片14的底部16的终端折页上的张力不如侧面部分15终端折页上的张力大。 This is because the tension on the bottom end flap 16 of gusset 14 is not as large tension on the side portions of the terminal 15 fold. 当然,当所有的终端折页的宽度都加倍时,联接片与板件之间连接的强度最大。 Of course, all of the width of the terminal when the flaps are doubled, the maximum strength of connection between the gusset plate member.

通过不折叠联接片每端的最后一个折页,可以实现联接片终端折页17、18宽度的延长或加倍,以便在与前板和后板11、12连接之前得到所要求的宽度。 By a final fold each end unfolded gusset, the gusset may be implemented width terminal folds 17, 18 extend or doubled to obtain the required width prior to connecting the front and rear panels 11,12. 或者是通过使未折叠的终端保留适当的长度来得到延长的宽度。 Or is obtained by reacting an extended unfolded width of the terminal to retain a suitable length. 当联接片上采用塑料或聚合物加强构件时,后一种方案比较理想,因为折叠的塑料材料具有折痕,它促使该材料保持其折叠状态,这样,在随后将联接片装配到或加工到板件上时就会发生困难。 When the plastic or polymer reinforcing member on the coupling piece, the latter embodiment ideal, because folded plastic material has creases, which cause the material to retain its folded state, so that, subsequent to fitting the gusset or machined into the plate a difficult time occurs on.

联接片14的终端折页17、18可以多种形式连接到前板和后板11、12上,如有必要,终端部分可以连接在板件的外表面或内表面上,只要终端部分的整个表面积均连在板件上即可。 Gusset terminal folds 17, 18 can be of a variety of forms 14 is connected to the front and rear plates 11 and 12, if necessary, the terminal portion may be attached on the outer or inner surface of the panel, as long as the whole of the terminal portion It is attached to the surface area on the board. 由于常见的板件包括内里部分和外表部分,从美学角度出发,最好将联接片终端部分连接在板件的内外两部分之间。 Since the common member comprises a plate portion and inside an outer part, from an aesthetic point of view, the coupling piece is preferably connected to a terminal portion between the inner and outer portions of the plate member. 为此,该终端部分在板件的两部分连接之前就位于前板和后板11、12的内层和外层之间,这样,当板件的两部分以上述方式连接时,联接片14的终端折页17、18就同前板11和后板12连在了一起。 For this purpose, the terminal portion prior to connection of the two parts of the plate member is located between the inner and outer front and rear plates 11, 12 so that, when the two panel members are connected to the above-described manner, the gusset 14 the folds 17, 18 to the terminal 11 with the front plate and the rear plate 12 are linked together. 另外,联接片14的终端部分可具有适当的粘性以增强其与板件的连接强度。 Further, the terminal portion of the coupling piece 14 may have an appropriate viscosity to enhance the connection strength of the plate member.

在将平板纸19折叠成联接片14之前,最好将TYVEK Before flat paper 19 is folded into gusset 14, will preferably TYVEK

(Dupont公司为旋转键合的烯族烃注册的商标)或某些其它防水和耐用材料附着在平板纸19上。 (Trademark of Dupont Corporation rotational bonded olefinic hydrocarbon registered) or some other waterproof and durable sheet material is attached to the plate 19. 与现有技术中已有的可伸缩文件夹相比,这种加强材料将提高文件夹10的强度和抗撕裂性。 Existing prior art expandable folder, this kind of reinforcing material to increase the strength and tear resistance folders 10.

联接片加强材料的第一位置是沿平板纸19一面的整个长度和宽度。 A first coupling position reinforcing sheet material 19 along one side of the flat paper entire length and width. 该加强构件将被当作加强层20。 The reinforcing member 20 will be used as reinforcing layer. 尽管加强层20最好只连接在平板纸19的将成为联接片14的外表面的那一侧,但类似的加强层20也还可连接在平板纸19的另一侧,以便两面均被强化。 Although the reinforcing layer 20 is preferably connected only in the flat paper sheet becomes the outer side surface 14 of the coupling 19, a similar reinforcement layer 20 may also be connected to the other side of the flat paper 19 so that both sides are reinforced . 加强层20将避免折页28因文件夹10反复伸展和收缩而再成型,并保护联接片14免受液体损害。 The reinforcing layer 20 to avoid folding the folder 28 due to repeated expansion and contraction of 10 and re-forming, and to protect the gusset 14 from liquid damage.

加强材料所处的第二个位置是在加强层20的某一部位上,这些地方随后将成为文件夹10的角23。 In which the reinforcing material is in the second position a portion of the reinforcement layer 20, where the folder 10 then becomes the angle 23. 在把平板纸19折叠成联接片14,而联接片14又被连接到前板11和后板12的表面上时就形成了角23。 In the flat paper 19 is folded into gusset 14, while the coupling piece 14 in turn is connected to the upper surface of the front plate 11 and rear plate 12 formed on the corner 23. 这种加强构件被称为角垫条21。 Such reinforcing member 21 is called the angular pad strip. 这些角垫条21最好如图4所示沿整个加强层20的整个宽度延伸。 These angles pad strip shown in FIG. 21 preferably extend along the entire width of the reinforcing layer 20 is the entire 4. 角垫条21与加强层20一起加固角23,而使其具有优良的抗撕裂性,正如下文将要讨论的那样。 Angular reinforcing mat strip 21 and the reinforcing layer 20 with angle 23, and it has excellent tear resistance, as will be hereinafter discussed above.

加强材料所处的第三个部位是平板纸19与加强层20的共同边缘25。 Reinforcing material which is a flat plate portion of the third sheet 19 and the reinforcing layer 20, the common edge 25. 这种加强构件被称为边缘垫条24,边缘垫条24沿平板纸19上部的全宽附着,覆盖共同边缘25,并沿加强层20上部的全宽附着(见图3、4、6)。 This reinforcement member is referred to as an edge pad strip 24, the edges of the pad 19 adhered to the full width of strip 24 along the upper portion of flat paper, covering a common edge 25, and is attached along the full width of the upper reinforcing layer 20 (see Fig. 3,4,6) . 边缘垫条24和加强层20一起,保护联接片14上部免受污物和水分损害,并为联接片14提供附加的抗撕裂能力。 Edges of the pad and the strip 24 with reinforcement layer 20, the protective sheet 14 from the upper coupling dirt and moisture damage, and to provide additional tear resistance of the gusset 14.

正如前面所指出的那样,最佳的加强材料是TYVEK As previously noted, the optimum reinforcing material is TYVEK

热塑薄膜,它包括一层用于板件11、12或联接片14连接的粘接剂。 Thermoplastic films comprising an adhesive layer of a gusset plate member 12 or 14 is connected. 不过,用其它的热塑薄膜或胶带获得类似的效果也是可能的。 However, a similar effect is obtained with other thermoplastic films or tapes are also possible. 而且,将纸条粘接或以其它方式连接到要加强的部位也是可行的。 Furthermore, the adhesive strip or otherwise connected to a portion to strengthen also possible. 如果这样,最好采用经过聚合物涂料处理过的纸材,或是采用塑料层压的纸,以便能防止水渗透。 If so, the best use of the treated paper via polymer coating, or laminated plastic of paper employed in order to prevent water penetration.

联接片14最好通过粘接、冲压或其它方式连接到前板11和后板12上,将终端折页17连在内层11a和外层11b之间,而内层11a和外层11b又相互连接在一起,通过粘接、冲压或其它方式将终端折页18连在内层12a和外层12b之间,而内层12a和外层12b也相互连接在一起。 Gusset 14 are preferably connected by gluing, stamping, or other means to the front plate 11 and rear plate 12, the terminal folds 17 is connected between the inner layer 11a and outer layer 11b, and the inner layer 11a and outer layer 11b and connected to one another by bonding, stamping, or otherwise attached to the terminal folds 18 between the inner 12a and outer 12b, and the inner layer 12a and outer layer 12b are also connected to each other. 因此,内层11a、12a实际上分别延伸到联接片的第一个和最后一个折页的最外端17a、18a。 Thus, the inner layer 11a, 12a actually extend into the first and last outermost end of the gusset flaps 17a, 18a. 还可以考虑将终端折页17、18仅与内层11a、12a的内表面分别相连,或是与外层11b、12b的外表面分别相连。 You can also consider only the terminal folds 17, 18 are respectively connected to the inner surface of the inner layer 11a, 12a, or 12b and the outer layer 11b is connected to the outer surface, respectively. 无论采用哪种连接方式,终端折页17都是沿前板11的竖边11c和底边11d放置,终端折页18沿后板12的竖边12c和底边12d放置。 Either method of connectivity vertical folding the terminal edge 11c of the front plate 11 and 17 are disposed along the bottom edge 11d, the terminal 12 after folding riser 18 along bottom edge 12d and 12c are placed.

正如上文所提到的,终端折页17、18最好具有延长的宽度,它至少为内部折页28宽度的两倍或者至少约为7/8英寸,无论如何是较宽一些。 As mentioned above, the terminal folds 17, 18 preferably have an extended width which is at least 28 times the width of the inner fold or at least about 7/8 inch, in any case is wider number. 这样,与现有文件夹的连接表面积相比,联接片14连接到前板11和后板12上去的表面积是非常大的,而且,终端折页17、18分别与前板11和后板12之间的连接也非常牢固。 Thus, the surface area compared to an existing folder is connected, the coupling plate 14 is connected to the front sheet 11 and the rear plate 12 up is very large surface area, and the terminal folds 17, 18 respectively with the front plate 11 and rear plate 12 between the connection is also very strong. 因此,如果在平行于前板11和后板12的方向上拉文件夹10的联接片14,联接片14不会象现有文件夹那样从前板11和后板12上分离或撕裂下来。 Thus, if the coupling piece 10 in a direction parallel to the front plate 11 and back plate 12 to pull the folder 14, the coupling piece 14 does not like the conventional folder as separate or tear down the front plate 12 and rear plate 11.

在文件夹10组装起来之后,还可以安装其它的加强构件,以使其具备比现有可伸缩文件夹更大的强度和抗撕裂能力。 After the folder 10 is assembled, additional reinforcement may be mounted member so as to have greater strength and tear resistance than conventional retractable folder. 该加强构件以内部加强片26的形式,沿着竖边11c从底边11d到顶边11e装在内层11a的裸露的表面上。 The reinforcing member in the form of internal reinforcing sheet 26, 11c installed from the bottom edge 11d to top edge 11e on the inner exposed surface 11a along the vertical side. 类似地,内部加强片22沿着竖边12c从底边12d到顶边12e装在内层12a的裸露的表面上。 Similarly, the internal reinforcing sheet 22 12c attached along the vertical side from the bottom edge 12d to top edge 12e on the exposed surface of the inner layer 12a. 内部加强片26、22能确保在联接片14已经充分展开、文件夹10张紧时,即在文件夹10过分展开时,内层11a、12a具有更大的阻止与联接片14分离的能力。 Internal reinforcement sheet 26, 22 to ensure that the gusset 14 has been fully expanded, the folder 10 when tensioned, i.e. when over-expand the folder 10, the inner layer 11a, 12a have a greater ability to prevent the separation of the gusset 14.

另外,外部加强片29沿着竖边11c从底边11d到顶边11e加装到外层11b的裸露的表面上。 Further, the installation of an external stiffener 29 11c along vertical side from the bottom edge 11d to top edge 11e on the exposed surface of outer layer 11b. 类似地,外部加强片30沿着竖边12c从底边12d到顶边12e加装到外层12b的裸露的表面上。 Similarly, the installation of an external stiffener 30 12c along vertical side from the bottom edge 12d to top edge 12e on the outer exposed surface 12b. 外部加强片29、30使文件夹10具有更大的结构稳定性和耐用性。 29, 30 so that the outer reinforcement sheet folder 10 having a greater structural stability and durability.

如上所述,在制成板件11、12的外层11b、12b之前,通过苯胺印刷技术将涂料27涂在卷筒纸板35上。 As described above, the outer layer 11b is made of a plate member 11, previously 12b, flexographic printing technique by coating the plate 27 on the web 35 coated. 苯胺印刷技术是一种公知的轮转印刷方式,由橡胶或其它弹性材料板将苯胺油墨或其它的化学物质层涂在各种表面上。 Flexographic printing technology is a well-known rotary printing, rubber or other elastic material plate flexographic inks or other chemical layer coating on various surfaces. 苯胺印刷技术极为适合在比较粗糙的表面上涂敷涂层27。 Flexographic printing technique for applying the coating 27 is extremely rough on the surface.

在本发明中所使用的苯胺印刷工艺最好重复两次以形成涂层27。 The flexographic printing process used in the present invention is preferably repeated twice to form a coating 27. 因此,涂层27最好包括一内层27a和一外层27b。 Accordingly, the coating 27 preferably comprises an inner layer 27a and an outer layer 27b. 如图7所示,在苯胺印刷过程中通常使用:贮墨槽40;装在贮墨槽40上的侧角刮板装置31;相对于贮墨槽40和刮板31运转的金属调节墨辊32;相对于金属调节墨辊32运转的印版滚筒33;以及压印滚筒34,它对压印滚筒34和印版滚筒33之间的卷筒纸板35施压。 7, is generally used in the flexographic printing process: fountain 40; side corner squeegee assembly mounted on the ink reservoir tank 40, 31; relative to the metal blade fountain 40 and regulating the operation of the ink roller 31 32; 34, its impression cylinder and the plate cylinder 34 the web 33 between the pressure plate and the impression cylinder 35; adjust the metal with respect to the operation of the ink roller 32 of the plate cylinder 33.

如上所述,涂层27是苯乙烯化的丙烯酸水基乳液36。 As described above, the coating 27 is a styrenated acrylic water-based emulsion 36. 然而,由于乳液36通过2号射流粘度计的粘度一般大于3分钟,所以在形成内层27a和外层27b之前需要将该粘度降低。 However, since the viscosity of the emulsion 36 through the jet viscometer No. 2 is generally greater than three minutes, it is necessary to reduce the viscosity before forming inner layer 27a and outer layer 27b. 因此,在纸板35第一次通过苯胺印刷工艺形成内层27a之前,贮墨槽40应装有由水和乳液36组成的流体36a。 Thus, the first board 35 before forming the inner layer 27a, fountain 40 to be filled with a fluid composed of water and an emulsion consisting of 36 36a by the flexographic printing process. 流体36a通过2号射流粘度计的粘度在55-60秒之间。 36a through the fluid jet viscometer No. 2 viscosity between 55-60 seconds. 类似地,在纸板35第二次通过苯胺印刷工艺形成外层27b之前,贮墨槽40里装有由水和乳液36组成的液体36b。 Similarly, the second web 35 before outer layer 27b is formed by a flexographic printing process, fountain 40 where a liquid 36b containing an emulsion of water and 36 thereof. 流体36b通过2号射流粘度计的粘度为25秒。 36b by the fluid jet viscometer No. 2 viscosity of 25 seconds.

如图8所示,通过已知的塑料成型技术在弹性橡胶板39的整个表面刻上小凹槽38。 As shown, the small grooves 388 engraved by a known plastic molding technique entire surface of the elastic rubber plate 39. 每平方英寸面积上小凹槽38的平均数一般大约为100,000个,不过,根据用途的需要,小凹槽38的数目可在30,000-300,000之间变化。 Average number of cells 38 per square inch is generally about 100,000, however, necessary to use, the number of small grooves 38 may vary between 30,000 to 300,000. 然后将橡胶板39固定在金属调节墨辊32的圆周上,小凹槽38的开口沿径向向外。 The rubber plate 39 is then fixed to the metallic roller 32 adjusted on the circumference of the ink, the small groove 38 opening radially outwardly.

该苯胺印刷装置通过贴着贮墨槽40里的流体36a转动金属调节墨辊32进行作业,金属调节墨辊32表面的小凹槽38里装着流体36a。 The flexographic printing apparatus through the slot 40 against the inside of the ink reservoir 36a in fluid regulating rotation of the ink roller 32 of metal working, the metal surface of the small adjustment grooves 32 of the ink 38 filled with a fluid roller 36a. 随着金属墨辊32的转动,刮板31将多余的流体36a从金属墨辊32的表面上刮下来。 With the rotation of the metallic ink roller 32, the blade 31 scrape excess fluid 36a from the upper surface of the metallic ink roller 32. 印版滚筒33接触金属墨辊32转动,将小凹槽38里的内含物转移到印版滚筒33的表面并在那里形成一层流体37a。 Plate cylinder 33 rotates in contact with the metallic ink roller 32, small grooves 38 in the contents transferred to the surface of the plate cylinder 33 and 37a there is formed a layer of fluid. 由于小凹槽38的大小是精确控制的,所以印版滚筒33上流体层37a的密度相当均匀,其偏差约为2%或更小。 Since the size of cells 38 are accurately controlled, the density of the upper plate cylinder 33 is relatively uniform layer of fluid 37a, which is a deviation of about 2% or less.

印版滚筒33连续转动,从而将均匀的流体层37a转移到纸板35上。 Continuously rotating plate cylinder 33, so that a uniform layer of fluid 37a is transferred to the web 35. 用以在印版滚筒33和压印滚筒34之间压印纸板35的压印滚筒34的辅助转动,确保流体层37a转移到纸板35上并在那里形成内层27a。 Cardboard platen 35 to assist rotation of the impression cylinder between the plate cylinder and the impression cylinder 33 of 34 34, 37a ensure that the fluid layer is transferred to the paperboard 35 and the inner layer 27a is formed there.

如图9所示,上面所述的苯胺印刷工艺随后又被重复一遍,贮墨槽40里装有流体36b,以便在内层27a表面形成外层27b,从而在纸板35上形成涂层27。 9, the flexographic printing process described above is then repeated again and again, in the fountain 40 is equipped with a fluid 36b, 27b so as to form the outer surface of the inner layer 27a, thereby forming a coating 27 on the web 35. 纸板35然后经过裁切台或冲压台,在这里将纸板35制成外层11b、12b。 Cardboard cut station 35 and then through or punching station, where the carton 35 is made of an outer layer 11b, 12b. 因此,涂在文件夹10外表面上的涂层27将能防止液体渗透到文件夹10里,并防止文件夹10因反复贴标签和撕标签而造成毁形。 Accordingly, the coating applied to the outer surface 10 of the folder 27 will prevent liquid penetration to the folder 10, the folder 10 and prevent due to repeated labeling and relabeling resulting disfigurement.

图10表示一个其基本结构和材料都与图1中文件夹10相同的可伸缩文件夹110。 Figure 10 shows a basic structure 10 and the same materials expandable folders in the file 110 in FIG. 1 with the folder. 文件夹110包括由可伸缩联接片116连在一起的前板112和后板114,联接片116构成文件夹110的底边和侧边118。 Folder 110 includes a front plate 112 and the back plate 116 by a telescopically coupled together sheets 114, 116 constituting the gusset folder base 110 and sides 118. 前板112由内侧部分120和外侧部分122组成。 The front plate 112 by the inner portion 120 and outer portion 122 composed. 类似地,后板114也由内侧表层124和外侧部分126组成,该文件夹沿着顶部开口,以便于将文件、资料和其它待存入的物品插入其中。 Similarly, the rear plate 114 by the inner surface 124 and outer portion 126 composed of an opening along the top of the folder, files in order, and other data to be inserted into the article.

为了加强联接片上部同板件之间的连接,将一圈加强材料134装在前板112、联接片116的侧面部分118和后板114上,从而包围整个文件夹110。 In order to reinforce the connection between the upper gusset plate member with the reinforcing material 134 turn mounted on the front plate 112, the side gusset 116 and rear portion 118 of plate 114, 110 so as to surround the entire folder. 加强带134装在邻近文件夹110各面顶缘的地方并覆盖连接在那里的联接片的终端部分130。 Reinforcing band 134 mounted in the terminal where folder 110 adjacent the top edge of each surface of the cover and connected thereto gusset portion 130. 尽管其它的尺寸也可使用,但加强带宽度最好约为1英寸。 Although other dimensions may be used, but the reinforcing tape width is preferably about 1 inch.

材料通常被制成胶带或织物,并被层压到基片(例如纸)上。 Material is typically made of tape or fabric, and laminated to a substrate (e.g. paper). 另外,其它热塑薄膜或胶带也能用于制成加强带134。 In addition, other thermoplastic films or tapes can also be used to form the reinforcing belt 134. 这些薄膜或胶带也可涂满粘合剂,或是用涂在加强带134或文件夹110上的适当的粘合剂或胶粘物将加强带134固定在文件夹110上。 These films or adhesive tapes may also be painted or coated with a reinforcing strip 134 or a folder suitable adhesive or glue on the reinforcing strip 110 is fixed on the folder 134 110. 含有玻璃纤维或其它纤维的胶带也可用作加强材料。 Tape containing glass fibers or other reinforcing fibers may be used as the material. 而且,复合的塑料薄膜/纸的层压制品,有或没有粘合剂衬垫,都可以用来制成具有一定强度甚至进一步提高了强度的胶带。 Moreover, the composite plastic film / paper laminate, with or without an adhesive backing, can be used to form a certain strength even further improve the strength of the tape.

如上所述,可伸缩文件夹110通常被所存放的文件和物品装至极限或是过量装满。 As described above, the expandable folder 110 is typically stored documents and articles are loaded to the limit or overfilled. 在将文件从文件夹中取出和重新放回去时,要将满载的文件夹拉伸或展开至其极限,对文件夹110的某些部位,如联接片116与板112、114的连接处产生张紧力,并经常导致在这些连接处撕裂。 When a file is taken out and put it back again from the folder, to full folder stretched or expanded to its limit, some parts of the folder 110, connector 116 and the gusset plates 112, 114 is generated tension, and often leads to tearing at these connections. 此外,当从文件柜或文件架上拿取文件夹时,往往是只抓住文件夹的一个板件将其拉出,这就经常会导致联接片116与板件112、114分离。 Further, when the pick folder from the file cabinet or shelf, is often only a catch plate to pull it out of the folder, which often leads to the gusset plate members 116 and 112 separated. 当装满的文件夹掉落在地上时,也会导致撕裂。 When a folder full of fall to the ground, can lead to tearing. 在联接片116和板件112、114的交接处装上加强带134,可以加强文件夹110,并在对文件夹施加拉伸或扩张之类的力时防止联接片同板件分离。 Preventing the sheet separated from the coupling member when the reinforcing plate mounted on the junction 116 and the gusset plate member 112, 114 with 134, 110 can enhance the folder, and a tensile force is applied to the folder, or the expansion or the like. 因此,本发明提供的是一种增加了强度和耐用性的可伸缩文件夹,这将延长文件夹的使用寿命。 Accordingly, the present invention provides an increased strength and durability of expandable folders, which will extend the life of the folder.

本发明的另一个实施例中,带状加强材料可以加装到文件夹的内表面,可以单独安装;或是与外部加强带134一起安装。 Another embodiment of the present invention, the strip-shaped reinforcing material may be installed to the inner surface of the folder can be installed separately; or reinforcing belt 134 together with an externally mounted. 内部加强带最好与上述外部加强带等宽,而且最好安装在邻近联接片116侧边118顶缘处,分别覆盖板112、114的内层120、124,并覆盖联接片116连接在那里的终端部分130。 Internal reinforcement strip is preferably reinforcing tape width with the external, and 116 is preferably mounted adjacent the side edge 118 of the gusset, the inner cover plate 112, 114, 120, 124, respectively, and cover gusset 116 connected thereto the terminal portion 130. 通过这种方式,内部加强带进一步加强联接片116侧边与板112、114交接处的那些最经常对文件夹施加拉伸力和扩张力的部位,从而使这些部位具有更优良的强度和耐用性。 In this manner, the internal reinforcing strip portions further enable those most often applied to the folder tensile force and expansion force of the junction 112 with the side edge of the gusset plate 116, so that these parts have better strength and durability sex.

内部加强带最好也是由一条TYVEK Internal reinforcing band is also preferably consists of a TYVEK

材料制成,它具有涂满粘合剂的背面,并被贴在前板112、后板114以及联接片116的侧面上。 Made of a material having a rear surface with adhesive-backed, and are attached to the side plate 112, rear plate 114 and the front 116 of the gusset. 如上所述,背面涂上或不涂粘合剂的其它合适的加强材料也可用作这种加强带。 As described above, other suitable reinforcing material, coated or not coated with an adhesive back surface of the reinforcing tape may be used as such.

图11表示本发明的另一个实施例,一种强化的可伸缩文件夹140,其中类似的部分采用相同的编号。 11 shows another embodiment of the present invention, a reinforced expandable folder 140 wherein like parts have been numbered. 在文件夹140上,两个分离的加强带142被用于强化联接片116与前板112和后板114之间的连接部分。 In the folder 140, two separate reinforcing bands 142 are used to strengthen the connection portion between the coupling plate 116 and the front plate 112 and rear plate 114. 每个加强带142均由同一种材料制成,并与上述其它加强带等宽,但是,加强带142只覆盖后板114外层126的一部分和联接片116的侧面118以及前板112的外层122的一部分。 Each of the bands 142 are made of the same material, and with the another reinforcing tape width, however, the reinforcing tape 142 covering plate 114 and the outer portion 126 of the coupling plate 118 and the front side surface 116 of the outer plate 112 a portion of layer 122. 加强带142分别装在前板112和后板114的外表面122和126上,盖过连接在那里的联接片116终端130的宽度。 Bands 142 are respectively mounted on the outer surface of the plate 112 and the rear plate 114 of the front 122 and 126, the width of the gusset 116 overshadowed connection terminal 130 there. 加强带142以这种方式,在将拉伸力或扩张力施加到联接片116与板件112、114的交接处时提供额外的强度和支承。 In this manner bands 142 provide additional strength and support when a tensile force or spreading force is applied to the junction of the gusset plate members 112, 114 and 116. 这样,加强带142可以防止联接片116从板件112、114上撕裂或分离,并增加文件夹的耐用性和寿命。 Thus, bands 142 of the gusset 116 can be prevented from tearing or separating from the upper plate member 112, and increase the durability and life of the folder.

如果需要,出于美学考虑可将加强带142的终端放在板件之间。 If desired, for aesthetic considerations can be strengthened with the terminal member 142 is placed between the plates. 在本实施例中,联接片在与加强带142和外侧板件相连之前,仅与内侧板件连接。 In the present embodiment, prior to the coupling piece is connected with the reinforcing plate 142 and the outer member, connected only to the inner plate member. 或者,还可以在外侧板件同联接片连接之前将加强带142同外侧板件连接,随后再将内侧板件同外侧板件相连。 Alternatively, the outer plate member may be coupled with the sheet before the reinforcing strip connected to the outer plate member 142 is connected with, and then subsequently attached to the inner panel with the outside panel. 第三种设计是,在联接片同板件连接之后将加强带142连接到内侧板件上。 A third design is the same after the gusset plate member 142 is connected with the reinforcing plate connected to the inner member. 在这种方案中,将加强带142延长到联接片的顶部,给这些部位提供抗撕裂性。 In this embodiment, the bands 142 extend to the top of the gusset, provide tear resistance to these parts.

或类似材料的塑料薄膜制成,或由一种复合的或层压的塑料涂层纸制成。 Plastic film or a similar material, or a composite of a paper or laminated into plastic coating.

至少在联接片的外表面和前板及侧板上设置一层加强层,以保护频繁使用的文件夹。 Provided at least on the outer surface of the front plate and the gusset plate and one reinforcing layer in order to protect the file folders used frequently. 所采用的最小量的加强件可以是一条带子,该条带盖住文件夹的底部联接片和联接片一板件的折线。 The minimum amount of the reinforcement member may be used a strap, a bottom gusset fold line and a gusset plate member covering strip folder. 该加强件在图20中即为点划线A和B以及坯件200的侧边212、214之间的区域,它在文件夹装着重的纸件或其他文件沿着一文件柜底部或沿着一工作台的表面被拖动时,保护该文件夹不受磨损并使该文件夹得以加强。 The reinforcing member in FIG. 20 is the region between the sides 212, 214 of the chain line A and B and the blank 200, which is installed in the folder of paper or other focused along the bottom of a file cabinet or in when the surface of a table is dragged, the folder protection from wear and tear and the folder can be strengthened. 该条带可在该纸通过裁切机的时候很容易地层压连接到该坯件上。 When the paper strip can be cut through easily laminating machine connected to the blank. 另外,该条带可胶贴到该纸上,或可以按这里所描述的那样被施以液体涂层。 Further, the strip may be adhesive label to the paper, or may press described herein is applied as a liquid coating.

图20的整个坯件200具有多折皱的水平凹陷208,该凹陷是被折叠或折皱而成的,以形成底联接片。 200 having a plurality of horizontal creases across the blank 20 of FIG recess 208, the recess is formed by folding or crease to form the bottom gusset. 这些联接片的折页208被用来伸缩文件夹,以装载大量的纸件。 The folding of the gusset 208 is sandwiched telescopic file used to load a large amount of paper. 都知道原先的那种非加强的联接片在其折线的地方是不结实的,因为该纸板在伸缩时会沿折线撕坏。 All know that the original non-reinforced gusset fold line in a place which is not strong, because the cardboard will stretch when tearing along the fold line. 可以确信,当该文件夹在使用中磨损时,该加强件有益于将纸板的磨损部分连接在一起。 It is believed that, when the folder is in use wear reinforcement member of the useful portion are connected together to wear cardboard. 然而,已经意外地发现,沿联接片的折叠线上附上加强件,实际上增加了文件夹的使用寿命,因为纸板不会象它未被加强时那样在折叠线处裂开或撕裂。 However, it has unexpectedly been found that reinforcing member attached along the fold line of the gusset, substantially increases the service life of the folder, because that split or tear at the fold line when the cardboard as it does not strengthen.

有利的是,使加强件延伸到前板和后板的将要粘接侧联接片的那一侧边区域上。 Advantageously, the reinforcement member extends into the front and rear panels to be bonded on that side of the coupling region side sheet. 该区域如图20所示为点划线C和D以及坯件200的侧边212、214之间的区域,它可以采用条带状的加强材料来加强。 The region 20 shown in FIG region between the sides 212, 214-dot chain line C and D and the blank 200, which can strip the strip reinforcing material to enhance employed. 这些条带应该比要被粘到该板件侧面的联接片的端部宽。 These strips should be compared to the plate adhered to the side end portion of the gusset width.

如图所示,沿着板的侧边部份,可以采用许多这样的条带,或者沿着坯件的每一侧在垂直于底部条带的方向用上单根条带。 As shown, along the side portions of the plate, it may be used many such strips, or a single strip spend in a direction perpendicular to the bottom of the strip along each side of the blank. 边侧条带可以置于邻近底部条带处,或者它们可以重叠在一起。 Side strips may be placed adjacent to the bottom strip, or they may overlap. 该条带的安排或设置对本发明并不是最关键的。 Strip arrangement of the present invention is not provided or the key. 对于手制的文件夹,该沿边侧或底部的加强材料可以制备成一种H形的整块,然后放到该坯件上。 Hand-made for the folder, the reinforcing material or the bottom side of the border may be prepared as an H-shaped piece, and then placed on the blank.

最好,采用的这种加强层为一单片或一片加强材料。 Preferably, this reinforcing layer is made of a single piece or as a reinforcing material. 在一个实施例中,该片材可以从位于边侧联接片的连接处上方的一个地方的前板处,通过底部联接片延伸到后板,抵达边侧联接片的连接位置之上的地方。 In one embodiment, the sheet may be, of the front plate extend from a place above the junction of the side gussets located through the bottom gusset to the rear plate, on the arrival of the local connection position of the side gussets. 这种方案类似于采用底部加强件,只是用了较宽条带的加强件,即,一个在点划线C和D以及坯件200侧边212、214之间延伸的条带。 This embodiment is similar to the bottom reinforcement member employed, except that the stiffener wide strip, i.e. a strip extending within a dashed line 200 between the side edges 212, 214, C and D and the blank tape. 该方案是优越的,因为作为文件夹的一加强点的联接片侧边连接处,也可以与底部联接片连接处一起来加强。 This embodiment is advantageous, because as a reinforcing point folder side gusset connection, may be connected together at the bottom gusset reinforcing.

可替代地,该加强片材可以在坯件200的整个外表面延伸并盖住该表面,以获得整个外部的加强。 Alternatively, the reinforcing sheet may extend over the entire surface and covers the outer surface of the blank 200 to obtain the entire outer reinforcement. 在该结构中,底部联接片,侧面联接片被连接处的前板和后板的侧面,以及通常装标记、标牌或其他文件标号的板件的顶部,所有的都被加强。 In this configuration, the side, bottom gusset, side gussets are connected at the front and rear panels, and a top plate is normally mounted tag, label or other document label, are all enhanced. 该加强层用来增强和保护文件夹的整个外表面不受频繁使用的磨损。 This layer is used to enhance and strengthen the entire outer surface wear is not frequently used to protect folders. 此外,当装满的和/或沉重的文件夹在文件抽屉里挪动时,该加强层起到防止可能出现的撕裂现象。 In addition, when filled and / or heavy folders in the file drawer move, the reinforcing layer serves to prevent tearing may occur.

该加强材料可以由广泛的各种材料组成,包括纸、纸板、聚乙烯、聚丙烯、(高密度聚乙烯合成纸)TYVEK The reinforcing material may be formed from a wide variety of materials, including paper, cardboard, polyethylene, polypropylene, (Tyvek) TYVEK

等类似的塑料薄膜。 Plastic film and the like. 该塑料薄膜可以包括天然的、合成的玻璃纤维或纤维束,以防止撕裂或磨损。 The plastic film may include natural, synthetic fibers or glass fiber bundles, to prevent tearing or abrasion. 该加强材料可以先简单层压制成坯件,然后才作适当的折叠线。 The reinforcing material may be made of a laminate blank briefly before making the appropriate fold lines. 可使用一种适当的如在加强件或文件夹上涂敷的粘接剂,来将选定的加强材料贴到文件夹上。 It may be used as a suitable adhesive or folder stiffener applied to the selected reinforcing material attached to the file folder. 并且,该加强材料可以包括一种粘接剂贴面,以简化对坯件的连接。 Further, the reinforcing material can include an adhesive backing to facilitate connecting to the blank. 作为单个片材或薄膜的一种替代,可以采用这种材料的加强条带,以便在选定的位置上提供加强作用。 As an alternative to a single sheet or film may be employed such reinforcing strip material to provide reinforcement in a selected position on the role. 再者,这些条带可以通过层压或用胶或粘接剂而连接到坯件上。 Furthermore, these strips with glue or adhesive may be connected to the blank by lamination or.

利用压力,可以将该加强材料连接到纸板上,运用层压很容易地实现了加强作用。 Using pressure, the reinforcing material may be attached to the paperboard laminate easily achieved using a reinforcing effect. 至于本实施例,加强材料和纸板可以简单地在两个辊子之间通过,这两个辊子给予必要的压力将这些材料相互之间粘结在一起。 As regards the present embodiment, the reinforcing material and the cardboard may simply pass between the two rolls, these two rolls to give the necessary pressure to bond these materials together with each other. 必要的话,也可能采用如聚合物或树脂的液体或溶液作加强材料,它们可以在粘结到纸板上后进行固化。 If necessary, also possible to use such a liquid or solution of the polymer or resin as a reinforcing material, they may be the cardboard to the adhesive is cured. 其他的聚合物或树脂涂料也可以用作加强件。 Other polymer or resin coatings may also be used as reinforcement. 此外,可以直接将数片塑料加强件挤压到该纸板上。 Further, the number of sheets of plastic may be directly extruded onto the reinforcement member paperboard.

还有,当聚合物或塑性材料用作加强层时,则该文件夹是防如象咖啡或水这样的液体的,在办公室这样的环境中,当文件夹从装文件的抽屉里抽出时它们很可能溅到文件夹上。 Also, when the polymer or plastic material is used as reinforcing layer, the folder is to prevent water, such as coffee or liquids such, in such an office environment, they are withdrawn from the folder when the file drawer mounted in the it is likely to spill folder. 还有,于最外层的板上采用整体的透明塑料或聚合物层作加强层可以得到其它的好处,即该板件可以较先前的文件夹更容易而且更便宜地染色或上色,因为该加强材料保护这些染色的或上色的部分,因此可使用较便宜的染料、着色剂或颜料。 Further, the outermost layer of a transparent plastic plate using the entire or polymer layer as the reinforcing layer may be further obtained the advantage that the plate can be more easily than previously and cheaper folder stained or colored, because these dyed or colored portion of the reinforcing material is protected and therefore may be less expensive to use a dye, colorant or pigment. 此外,可以采用较经济的方法,应用这些颜料、着色剂和染料,而且,可以使用经着色的加强层来赋于文件夹理想的色彩。 Furthermore, more economical method of application of these pigments, colorants and dyes, and may be used by the colored reinforcing layer folder impart the desired color.

图21示出了用于图20的坯件200的边侧联接片220。 FIG 21 shows a side gusset 220 for the blank sheet 200 of FIG. 20. 该联接片由抗撕裂或抗破裂的材料,如聚乙烯、聚丙烯、TYVEK The gusset tear or rupture by anti materials, such as polyethylene, polypropylene, TYVEK

的塑料薄膜及其类似物制成。 Made of plastic film and the like. 该塑料薄膜可以含有天然的、合成的玻璃纤维或纤维束,以进一步防止撕裂或磨损。 The plastic film may contain natural, synthetic of glass fibers or bundles of fibers, to further prevent tearing or abrasion. 此外,该联接片可以由涂敷塑料的纸复合材料或层压材料组成。 In addition, the coupling piece may be composed of plastic coated paper composite or laminate.

图21的边侧联接片具有许多垂直的凹陷222,它们被折叠或折皱来形成用来使文件夹张开以便盛装更多的文件的联接片折页。 FIG side gusset 21 has a plurality of vertical recesses 222, which are formed by folding or creasing of the gusset folds to enable to open a folder containing more files. 先前的非加强联接片易于在这些折叠线之处损坏,因为在张开或折叠时,该纸板会沿该折叠线撕裂。 Previous non-reinforced gussets easily damaged at these fold lines, the open or folded since the cardboard tear along the fold line. 如上所述,本联接片220的加强实际上增加了文件夹的使用寿命,这是因为该纸板并不会象它未经此处所述的这种加强的那样,在折叠线处断裂或撕裂。 As described above, this strengthening gusset 220 substantially increases the useful life of the folder, because such as the reinforcing board as it will not be described herein without fracture or tear at the fold line crack.

图21的边侧联接片还能够用于加强通常的文件夹的边侧联接片。 FIG side gusset 21 can also be used to reinforce the side gusset of a conventional folder. 该联接片220可以在通常的联接片连接好以后再连接到任何文件夹的板上。 The gusset panel 220 can then be connected to any folder after the conventional gusset connected. 例如对于五片文件夹结构来说,联接片220可在通常的联接片连接好以后被连接到内板的外表面。 For example, five folder structure, the coupling plate 220 may be connected to an outer surface of the inner panel at a later gusset generally connected. 按照本发明所述的各种替换的实施例,可以引伸构思出另外的方案。 Various alternative embodiments according to embodiments of the present invention, the program further extension contemplated.

边侧联接片的端部230在被连接到板件上时,可以为标准宽度,即基本上与联接片折页的宽度相同,或为以上所述的联接片折页的两倍宽度,以增加强度。 An end portion of the side gusset 230 when connected to the upper plate member, may be a standard width, i.e., substantially the same as the width of the gusset folds, or of more than twice the width of the gusset folds to Increased strength. 例如对于图20的特定坯件来说,在加强的时候,最好使边侧联接片的端部连接到该板件的外侧。 For example, certain of the blank of FIG. 20, the reinforcing, the best that the side gusset end connected to the outside of the plate member. 每个坯件用两个这种边侧联接片来组成文件夹。 Each of such two blanks with side gussets to the composition of the folder. 可以利用适当的粘接剂,将其涂敷于板或两端部而将这些端部230连接到该板上。 Suitable adhesive may be utilized, which is applied to both ends of the board or the board 230 is connected to the end portions of these. 另外,该边侧联接片端部230可以包括一种粘接剂贴面,以简化对这些板件的边侧的连接。 Further, the side gusset end portions 230 can include an adhesive backing to facilitate connecting to the sides of the panels. 虽然最好将这些端部粘接到板件的外侧,但是,按照某种文件夹的设计要求,它们可以被连接到板的内侧。 While these end portions is preferably bonded to the outer plate member, however, in accordance with the design requirements of a certain folder, which may be connected to the inner panel.

在一个实施例中,边侧联接片的底部与底部联接片相对的角并不连接,图22中的240示出了构成这种结构的文件夹。 In one embodiment, the angle of the side gussets at the bottom and an opposite bottom gusset are not connected, in FIG. 22 240 shows such a structure configuration file folder. 虽然对于某些可伸缩的文件夹而言,这种结构是满意的,但是,最好在角接合处将这些组件连接起来,以及最好加强这样的连接。 Although for some scalable in terms of folders, this structure is satisfied, but preferably at a corner joint connecting these components, and is best strengthen such connections. 通过简单地延长边侧联接片的长度,并将边侧联接片的端部沿图21所示的线226切断以形成一接片224,把边侧联接片的底部沿着位于两切断部分之间延伸的点划线228折叠,然后把接片连到板上并将在两接片之间延伸的边侧接片的下部232连到底部联接片上,这样便形成了一种连接。 By simply extending the length of the side gusset, and the cutting edge line shown in the side gusset end portions 226 in FIG. 21 to form a tab 224, the bottom of the side gussets located along the two cutting portions dot chain line 228 extending between the folded and the tab is connected to the lower plate and between the two side tabs 232 extending tabs even in the end portion of the gusset, so that they form a connection. 如上所述,可以利用胶或一种粘接剂,将边侧联接片220的接片224和下部232粘到板件和底部联接片上,胶或粘接剂可涂施在任一构件上。 As described above, may utilize glue or an adhesive, the side gusset 220 tabs 224 and the lower member 232 adhered to the upper plate and a bottom gusset, glue or adhesive may be applied on either a coated member.

可此外,角部加强件可由边侧联接片上延伸的一片或一条单独的加强材料加贴于底部联接片上以及部分加贴于板件上而实现。 Can Further, the corner portions may be formed on the reinforcing member side gusset extends a reinforcing material or a separate sheet, and affixed to the bottom portion of the coupling is achieved affixed to the upper plate member. 该角部加强件可以由耐撕裂或耐破裂的材料制成,如上所述的用作边侧联接件的那种材料。 The corner portion formed reinforcement may tear or rupture resistant-resistant material, as described above, that side of the coupling material. 最好,角部加强件由涂敷塑料的纸复合材料或层压材料制成,该塑料复合材料及角部加强件涂敷胶或一种粘接剂来进行连接。 Preferably, the corner reinforcing member is made of a plastic coated paper composite or laminate, composite, and the plastic corner reinforcing member is applied to an adhesive or glue connection.

图23所示为整体坯件实例的最佳文件夹结构250,其中类似于图20-22中描述的部件具有相应的标号。 Figure 23 shows the best overall file folder structure example of the blank 250, wherein components similar to those described in FIG. 20-22 have corresponding reference numerals. 除了坯件的整个外面作了加强以及使用了具有用来连接底部联接片的接片224的边侧联接片220外,还有许多进一步加强文件夹和获得最佳的使用寿命的特征。 In addition to the entire outside of the reinforcing blanks were used and side gussets for connecting tabs having a bottom gusset 224 220, there are a number of features to further enhance the folder and optimum lifetime. 边侧联接片的顶部用图14-19中的附加结构252之一来加强,而文件夹的角部用涂塑纸板复合材料254的附加件来进一步加强。 Top side gusset to one additional reinforcing structure in FIG. 14-19252, and the angle of the folder unit further additional reinforcing member 254 of the plastic composite board. 为了增强文件夹的外表,坯件200的板件202、206的外表面装有附加的前板和后板256。 To enhance the appearance of the folder, the outer surface of the plate member 202, 206 of the blank 200 with additional front plate and the rear plate 256.

可替换地,不用附加的板件256,而是沿坯件200的板件202、206的侧边,在边侧联接件/板件连接件的上面设置复盖条。 Alternatively, without an additional plate 256, but the sides 202, 206 of plate member 200 along the blank, provided on the coupling member side / top panel connector cover strip. 在这一方案中,复盖条可由一种上述的加强材料制成,以增加文件夹这些部位的耐磨性。 In this embodiment, the cover strip may be one of the aforementioned reinforcing materials, in order to increase the wear resistance of these parts of the folder.

采用通常的五片文件夹的结构可以装成一种类似的文件夹,即前板和后板,每个都具有内板件和外板件,并都由一联接片连接。 Structure using a conventional five folders may be loaded into a similar folders, i.e., the front and back panels, each having an inner plate and the outer plate member, and is connected by a gusset. 在本实施例中,前板和后板的内板件和外表面可以包括一层复盖整个外表面的塑料加强层。 In the present embodiment, the inner and outer surfaces of the front plate member and rear plate may comprise a layer of plastic covering the entire outer surface of the reinforcing layer. 该联接片最好由TYVEK The gusset is preferably made of TYVEK

层压纸材制成。 Made of laminated paper. 最有利的是,采用红皮夹作外板件的材料和前板内板件的材料,而后板的内板件由马尼拉纸制成。 Most advantageously, with red wallet as the material of the front panel and the inner panel outer plate member, and then the plate member by an inner panel Manila paper. 该联接片端部被连接到内板件外表面的加强件上,然后才连接外板件。 The coupling piece is connected to an end portion of the reinforcing member of the outer surface of the inner panel, outer panel before connecting. 如上所述,可以在联接片的顶部、在联接片的角部、在外板件的外表面或内板件的内表面连接附加的加强件。 As described above, at the top of the gusset can be connected additional reinforcement at the corners of the gusset, the outer surface or the inner surface of the outer plate member of the panel.

图24和图25所示为一种另外优选的可伸缩文件夹260,其中,类似于图20-21中所示的部件具有相应的标号。 Further preferred as a shown in FIG. 24 and FIG. 25 expandable folder 260, which is similar to components shown in FIGS. 20-21 have corresponding reference numerals. 坯件的外表面加强件262正好从一个位于板件上的边侧联接片连接处264上方绕过底部联接片到另一个板件上的正好边侧联接片连接处上方的一个位置上。 The outer surface of a blank from a reinforcement member 262 just on the side gusset connection plate positioned above the bottom piece 264 is coupled to just bypass side gusset on the other plate member is connected at a position above the upper. 如果需要的话,可以通过遮掩边侧联接片的连接230,贴上附加的板件或复盖条,以增强文件夹的外表。 If desired, masking can be connected by a side gusset 230, additional paste covered plate or strip, to enhance the appearance of the folder. 还有,坯件的外表面加强件可以延长到后板件206的外表的顶部,以增强要装标签或别的文件标示的区域和减小压坏或弯折后板件顶部的可能性。 Further, the outer surface of the blank of reinforcement may extend to the top of the outer member 206 of the rear plate, to be installed to enhance the area of ​​the label or other documents marked and reduce the likelihood of crushing or bending the top panel.

使用通常的五片文件夹结构还可以构成一种类似的文件夹。 Using a normal five folder structure may also constitute a similar folder. 在本实施例中,如图24所示,前板和后板的内板件的外表面包括一层复盖底部的外表面的塑料加强层。 In the present embodiment, as shown, the outer surface of the front and rear panels of the inner panel member 24 comprises a layer of plastic covering the outer surface of the bottom reinforcement layer. 该联接片最好由TYVEK The gusset is preferably made of TYVEK

这种材料的层压纸制成,并以红皮夹作为外部材和前板的内板材,而后板的内板材由马尼拉纸制成。 This laminate material to a paper, and red wallet as the inner sheet and the outer sheet of the front plate, then the plate sheet by Manila paper. 该联接片端部被连接到内板件外表面的加强件上,然后再连接外部板材。 The gusset end portions are attached to the inner panel reinforcement member outer surface of the member, and then connect the external sheet. 如上所述,附加的加强件可以贴到该联接片的顶部、该联接片的角部、外板件的外表面或内板的内表面上。 As described above, additional reinforcement can be attached to the top of the gusset, on the inner surface of the corner portion of the coupling piece, the outer surface of the outer panel or the inner panel.

虽然图22-25的优选结构包括将边侧联接片连接到坯件外表面上的加强件上,但还有可能在坯件的内表面上设置这种连接。 While the preferred structure 22-25 includes side gussets connecting the reinforcing member to the outer surface of the blank, it is also possible in this connection is provided on the inner surface of the blank. 在本实施例中,加强材料以上述用于外部区域的相同方式贴到坯件的内表面上。 In the present embodiment, the reinforcing material in the same manner as described above for the outer region is attached to the inner surface of the blank. 对于本实施例来说,前面描述的坯件可以很容易地翻过来,即其外表面可以变成内表面。 For this embodiment, the blanks described above can be easily turned over, i.e., the outer surface of the inner surface may become.

本发明的胶和粘接剂也体现了较现有技术的另一个优越之处。 Adhesive and the adhesive of the present invention over the prior art also reflects another significant advantages. 一般而言,冷的胶或粘接剂通常都用来连接好标准的可伸缩的文件夹的组件。 Generally, cold glues or adhesives are commonly connected to a standard component used for scalable folder. 由于本发明的组件作了结构改进,这种常用的胶也适用于制作本发明的文件夹,甚至用于组件之间如联接片与板件之间有较大改进的连接处,然而,此处最好还是用热熔粘接剂。 Because components of the present invention is made to improve the structure of this gel it is also commonly used for the production of the present invention, folders, and even a greater improvement in the connection between the plate member and the coupling between the sheet components such as, however, this at best with hot melt adhesive. 这些粘接剂有效地使一个组件封接于另一个组件。 These adhesives effectively seal one component to another component. 从而基本上消除了粘接剂连接点连接不好的可能性。 Thereby substantially eliminating the possibility of the adhesive is not the point of attachment. 在多数情况下,连接点的强度较组件的强度大。 In most cases, the strength of the assembly strength than a connection point is large.

另一个有利的方法是利用有粘结力的连接将两塑料薄膜固定在一起。 Another advantageous method is to use adhesive force has connected the two plastic films together. 而且,连接处的强度等于塑料材料的强度,因此连接点几乎不破损,即使发生破损,也不会撕坏或损坏板件。 Further, the strength of the connection is equal to the strength of the plastic material, so that the connection point is hardly damaged even if damage occurs, it will not tear or damage the plate.

此外,本发明的另一个新的方案是用于文件夹组件的材料,例如,板件、联接片和加强件可以由一种合成纸,如由DURALON In addition, another new aspect of the present invention is a material for the folder assembly, e.g., plate, sheet and the reinforcing member may be coupled from a synthetic paper, as indicated by DURALON

(Arlon公司(Arlon,lnc)的注册商标)制成,该材料在两层普通纸之间夹一层聚酯材料。 (A registered trademark of Arlon Corporation (Arlon, LNC)) is formed, which material is sandwiched between two layers of a polyester plain paper material. DURALON DURALON

材料具有高强度并耐撕裂。 Material having high strength and tear resistance. 而且,这些组件可以完全由塑料制成,其连接利用超声波焊接完成。 Also, these components can be completely made of plastic, which is connected by ultrasonic welding to complete. 这种结构在所有上述的材料中具有最高的防潮湿性和耐磨性。 This structure has the highest moisture and wet abrasion resistance of all the above materials. 由于这些组件是被焊接在一起的,其连接片还与用来制造组件的材料的强度一样强。 Since these components are welded together, which connection piece further strength as strong as the material used to make assembly. 使用这些改进的粘接材料和连接方式的另一个优点是,由于结构加强件的特性已经综合到组件材料上,因此可以不采用上述的结构加强件。 Another advantage of the adhesive material and the use of these connections is improved, due to the characteristics of the structural reinforcement material has been integrated to the assembly, and therefore may not be the above-described structural reinforcement member. 而且,由于采用这种加强件的连接处的强度基本上等于组件材料的强度,因此,可以不采用联接片的端部延长件或其他连接的整件固定件。 Further, since the strength of such a connection reinforcement member is substantially equal to the strength of the component materials, and therefore, may not be used to extend an end portion of the gusset member or other member connected to the fixing piece.

现参见图26,其中图示了一整体坯件270,该坯件包括形成文件夹的一前板件272、底部和边侧联接片274和后板件276。 Referring now to Figure 26, there is illustrated an integral blank 270, the blank comprises a front panel member 272, bottom and side gussets formed folder 274 and the rear plate member 276. 坯件的后面,即形成文件夹外表面的那一面,是以平展的位置示出,之后将折成联接片折线278和板-联接片的折线280。 The back of the blank, i.e., the outer surface of the folder is formed that side, flat position is shown, after which the folded gusset panel fold lines 278 and - 280 of the gusset fold lines. 该坯件270可以用相应于制作图20的坯件200的上述任一种材料制成。 The blank 270 can correspond to any of the aforementioned material 200 of FIG blank 20 is made. 对于要求最大强度的可伸缩文件夹来说,坯件270可以用聚乙烯、聚丙烯、商品名为TYVEK For maximum strength required expandable folder, the blank 270 can be named TYVEK polyethylene, polypropylene, commodity

的高密度聚乙烯合成纸等类似物的塑料或涂塑纸复合材料或其层压结构制成。 A synthetic paper made of a high density polyethylene plastic or other like material or plastic coated paper composite laminate structure.

如果用纸板作为坯件的材料,则至少在联接片的外表面上和在前板和后板件上设置一加强层,其设置方式与上述图20的坯件200所描述的一样。 If used as the material of the blank of cardboard, at least the outer surface of the coupling piece and a reinforcing layer disposed on the front plate and the rear plate member, which is provided as the above-described embodiment the blank 200 of FIG. 20 described.

最好,该加强层沿坯件270的整个外表面延展并将其复盖,以便加强整个外部。 Preferably, the reinforcing layer 270 along the entire outer surface of the blank and extend to cover, in order to strengthen the entire outer. 这就便于制成整个文件夹都由塑料或涂敷塑料膜的纸的层压材料或复合材料组成的文件夹。 This facilitates file folder is made by the entire plastic coated plastic film or laminate or a composite material consisting of paper clips. 采用这样的材料,甚至普通的五件文件夹结构也具有增强强度和增加了耐用与耐磨性的组件的连接。 With such materials, even a normal five folder structure has enhanced strength and increased durability of the connection assembly and wear resistance. 当用塑料来制作时,可以采用超声波焊接来装制文件夹。 When used to make plastic, can be made by ultrasonic welding means folder.

通过沿坯件270的A、B、C、D线切断到它的与线280的相交处,来构成边侧联接片。 Cut to its intersection with the line 280 through 270 A, B, C, D of the blank along a line, to constitute the side gussets. 在作了这些切断之后,则在联接片上作折线,以折线280向上弯折前板和后板,通过分别沿割线AC和BD之间延伸线折叠,使边侧联接片向上弯折,然后沿线280弯折边侧联接片端部282,使该端部都折到如图所示的板件之后,或使端部弯折到板件之前,这样便形成了文件夹。 After these were cut, the work on the gusset fold line to the fold line 280 is upwardly bent front and rear plates, between the AC and BD respectively by cut line extending along the fold line, so that the side gussets folded up, then after folding along the line 280 of the side gusset end portions 282 so that the end portions are folded to the plate member as shown, or to the end portion of the plate member prior to folding, thus forming the folder. 然后,根据坯件的材料,这些端部被用胶或粘接剂,采用粘接力粘结或超声波焊接,连接到该板件上。 Then, depending on the material of the blank, the ends are glue or adhesive bonding using an adhesive or ultrasonic welding force, coupled to the plate member. 图27示出了制作好的成品文件夹。 27 shows a folder create finished products. 如果需要的话,后面板件的角可以切成园角。 If necessary, the rear panel corner piece can be cut into rounded corners.
