Description

用于纸张的包 bag for paper

本发明涉及一种如权利要求1的前序部分中所述的、用于纸张(例如打印纸和影印纸)的包。The invention relates to a pack for paper, such as printing and photocopying paper, as stated in the preamble of claim 1 .

在已知技术中，以纸张形式提供的办公纸(例如A4尺寸的影印纸和打印纸)通常包装在波纹纸板盒中，各盒装有5个纸张包，这些纸张包包装在各纸张包装材料中。各纸张包(称为令包装)包含500张A4尺寸的纸张。通常，出售的最小纸张捆由上述500张纸组成。这样包装的纸张捆的一个问题是在用于台式打印机、传真机和影印机时有相对大量的纸张。当打开令包装时，可能一次只使用该包的一半或更少。大部分台式打印机使用非常少的纸张。这意味着从纸张包装中取出的纸张可能在经过一段时间后由于不使用和并不由包装保护而变干或改变它们的特性。变干可能导致纸张中的静电增加，并导致纸张相互粘附，这将引起打印故障或者在打印机或其它使用纸张的机器的纸张线中引起阻塞。In the known art, office paper provided in paper form (such as A4 size photocopying paper and printing paper) is usually packaged in corrugated cardboard boxes, each box contains 5 paper packs, and these paper packs are packed in each paper packaging material. middle. Each paper pack (referred to as a ream pack) contains 500 sheets of A4 size paper. Typically, the smallest paper bundles sold consist of the aforementioned 500 sheets. One problem with such packaged paper bundles is the relatively large amount of paper when used in desktop printers, fax machines and photocopiers. When unpacking a ream, one half or less of the pack may be used at a time. Most desktop printers use very little paper. This means that papers taken out of their packaging may dry out or change their properties over time due to non-use and not being protected by the packaging. Drying out can cause static electricity to build up in the paper and cause the paper to stick to each other, which can cause printing failures or jams in the paper line of a printer or other machine that uses paper.

本发明的目的是消除上述问题，并尽可能地获得便宜和容易使用的打印和影印纸张包，该纸张包适用于台式打印机和其它相对较低量的用途。本发明的目的还在于获得一种打印和影印纸张包，它能够在保护包装局部就位的情况下布置在使用纸张的机器内部，这将保护纸张防止变干和以其它方式改变在机器中的纸张的特性。本发明中所述的包的特征由权利要求1的特征部分中所述。本发明的其它实施例的特征在其它权利要求中介绍。It is an object of the present invention to eliminate the above-mentioned problems and to obtain, as far as possible, an inexpensive and easy-to-use printing and photocopying paper pack suitable for desktop printers and other relatively low-volume applications. It is also an object of the present invention to obtain a package of printing and photocopying paper that can be arranged inside a machine where the paper is used, with a protective packaging locally in place, which will protect the paper from drying out and otherwise altering the quality of the paper in the machine. properties of paper. The bag described in the invention is characterized by what is stated in the characterizing part of claim 1 . Other embodiments of the invention are characterized in other claims.

本发明的方案的优点是该包非常便宜和快速地制造。另一优点是包材料具有很高的抗破裂和撕开性，这样，该包保护它内部的纸张免受机械应力。又一优点是包材料可成卷获得，这使浪费量最少。另一优点是包装材料使用非常少的塑料或不使用塑料，这对于环境友好且能够便宜地回收。另一优点是包装材料非常防潮，尽管它没有单独的塑料层。另一优点是包装设有至少一个开口条，该开口条使得包装更容易打开。另一优点是合适量的纸张用于家庭用途，且包可以在防潮保护包装仍然局部就位的情况下整个布置在打印机或影印机中，这意味着当它们缓慢使用时，纸张也不会太容易变干或太快改变它们的其它特性。本发明的方案的又一优点是在使用纸张的机器中可以省略一些引导纸张的容易破裂部件，这使得机器与已知的小型打印机和影印机相比更可买得起、更简单、更可靠和更无需保养。The advantage of the solution of the invention is that the bag is very cheap and fast to manufacture. Another advantage is that the bag material is highly resistant to breaking and tearing, so that the bag protects the paper inside it from mechanical stress. A further advantage is that the packaging material is available in rolls, which minimizes the amount of waste. Another advantage is that the packaging material uses very little or no plastic, which is environmentally friendly and can be recycled cheaply. Another advantage is that the packaging material is very moisture resistant, although it does not have a separate plastic layer. Another advantage is that the package is provided with at least one tear strip which makes opening the package easier. Another advantage is that the right amount of paper is used for home use and the pack can be arranged entirely in a printer or photocopier with the moisture protection wrap still partially in place, which means that when they are used slowly the paper is not too Tend to dry out or change their other properties too quickly. A further advantage of the solution of the invention is that in machines using paper some easily breakable parts guiding the paper can be omitted, which makes the machine more affordable, simpler and more reliable than known small printers and photocopiers And more maintenance-free.

下面将利用实例参考附图来详细介绍本发明，在附图中：Below will utilize example to introduce the present invention in detail with reference to accompanying drawing, in accompanying drawing:

图1显示了本发明的包从侧面斜向看时的视图；Figure 1 shows a bag of the invention viewed obliquely from the side;

图2显示了图1的包从侧面斜向看时的视图，且一端从开口条向前除去；Figure 2 shows the bag of Figure 1 viewed obliquely from the side with one end removed forward from the tear strip;

图3以简化和放大的形式显示了用于本发明的保护包装的典型层结构；Figure 3 shows in simplified and enlarged form a typical layer structure for the protective packaging of the present invention;

图4以简化和放大的形式显示了用于本发明的保护包装的另一层结构；Figure 4 shows in simplified and enlarged form another layer structure for the protective packaging of the present invention;

图5以简化和放大的形式显示了用于本发明的保护包装的第三层结构。Figure 5 shows, in simplified and enlarged form, the third layer structure for the protective packaging of the present invention.

图1和2显示了本发明的纸张包1，该纸张包包含比普通的令包装(该令包装具有500张纸)更少量的A4尺寸纸张。纸张的数目可以为例如大约100-400，优选是例如200-300，更优选是例如250，这是在制造包含500张纸的令包装时很容易设置的量。纸张12包在由较强保护包装2形成的包1的内部。包由基于卷材的包装2来制成，该包装2在包1的制造过程中直接从卷材中拉出，并在正确长度处切断，然后，包装2卷绕到例如纸张12上，这样，包的顶部、底部和两个较长侧面形成连续包装件，在该包装件中，包装2的后端8交叠在包装的前端7上一合适的量，并使它的内表面向下胶粘在前端7的外表面上。包装2的隐藏前端7利用虚线来表示。包装2的后端8优选是布置在成组的包的顶部，特别是靠近它的其中一个较长拐角。在包1的各端处具有至少一个外部折片3和4以及内部折片5和6，这些折片布置成至少局部交叠，并合适地胶粘在一起。在端部的折片形成用于包中的办公纸张的端部的加强保护，在该端部处，即使很小的意外也很容易损坏多个纸张。Figures 1 and 2 show a paper pack 1 of the present invention containing a smaller amount of A4 size paper than a conventional ream pack (the ream pack has 500 sheets). The number of sheets may be eg about 100-400, preferably eg 200-300, more preferably eg 250, which is an easily settable amount when making a ream package containing 500 sheets. The paper 12 is wrapped inside the pack 1 formed by a stronger protective wrap 2 . The pack is made from a roll-based package 2 that is pulled directly from the roll during the manufacture of the pack 1 and cut at the correct length, after which the pack 2 is wound onto, for example, paper 12 such that , the top, bottom and two longer sides of the pack form a continuous package in which the rear end 8 of the pack 2 overlaps the front end 7 of the pack by an appropriate amount with its inner surface facing downwards Glue on the outer surface of the front end 7. The hidden front end 7 of the package 2 is indicated with dashed lines. The rear end 8 of the package 2 is preferably arranged at the top of the group of packs, in particular near one of its longer corners. At each end of the bag 1 there is at least one outer flap 3 and 4 and inner flaps 5 and 6 arranged to overlap at least partially and suitably glued together. The flaps at the ends form enhanced protection for the ends of the office papers in the pack, where even a small accident can easily damage multiple sheets.

图1还具有显示开口条10的虚线，该开口条10在包装切断之前胶粘在包装2的内表面上。这样，开口条10与包装2具有基本相同的长度或优选地开口条10的长度大于该包装2的长度。开口条10布置在离成组的包1的端部合适水平距离处。合适距离例如是在包装2打开后使得包1中的纸张12的端部13只是恰好可见，并充分使得打印机或影印机能够良好地抓住最顶部纸张的端部13。纸张的其余部分保持在包装的较大部分中受到保护。Figure 1 also has dashed lines showing the tear strip 10, which is glued to the inner surface of the package 2 before the package is severed. In this way, the tear strip 10 has substantially the same length as the package 2 or preferably the length of the tear strip 10 is greater than the length of the package 2 . The tear strip 10 is arranged at a suitable horizontal distance from the end of the pack 1 of the group. A suitable distance is eg such that the ends 13 of the sheets 12 in the pack 1 are just barely visible after the package 2 has been opened, and are sufficient to allow a printer or photocopier to have a good grip on the end 13 of the topmost sheet. The rest of the paper remains protected within the larger portion of the package.

在开口条10的端部，包装的边缘与包装2的端部8对齐地切开，这样，在开口条10的各侧是合适长度的切口11，该切口在纵向上与开口条10对齐。这使得很容易抓住开口条10的端部，且包装2可以恰好环绕包1相对于纸张12的位置横向地被撕开。开口条10的材料可以变化，但是它总是充分坚固，并基本没有弹性或具有非常小的弹性。At the end of the tear strip 10 the edge of the package is cut in alignment with the end 8 of the package 2 so that on each side of the tear strip 10 is a cut 11 of suitable length which is longitudinally aligned with the tear strip 10 . This makes it easy to grasp the end of the tear strip 10 and the package 2 can be torn transversely just around the position of the package 1 relative to the paper 12 . The material of the tear strip 10 can vary, but it is always sufficiently strong and has little or no elasticity.

图2显示了图1的包1，该包在开口条10处打开。这里，开口条10已经被撕开，且包装2的一端已经被除去，留下包装2的、在包1之上的部分2a，该部分2a覆盖包的几乎全部，该部分2a设计成当在打印机或影印机中时保护纸张12防潮和防止其它变化。这样在一端打开的包1设计成作为包含在包装的剩余部分2a中的单个堆或捆而被放入机器中。FIG. 2 shows the bag 1 of FIG. 1 opened at the opening strip 10 . Here, the tear strip 10 has been torn open and one end of the package 2 has been removed, leaving a portion 2a of the package 2 above the package 1 which covers almost all of the package and which is designed to be Protects the paper 12 from moisture and other changes while in a printer or photocopier. The pack 1 thus opened at one end is designed to be put into the machine as a single stack or bundle contained in the remainder 2a of the pack.

本发明的包装2必须满足与保护性、破裂强度、抗撕开性、可胶接性和可打印性相关的某些需要。此外，包装2必须保护包的内容物防潮。因此，包装2的材料例如可以形成为这样，即基层15由纸张组成，添加剂在制造过程中通过在造纸机的涂覆部分中的在线涂覆而以合适的量添加在该纸张上，该添加剂由塑料、聚合物混合物或延缓水汽吸收的类似合适材料16来构成，该合适的量使得包装2的水蒸气传输率(WVTR)(根据ISO 2528：1995来计算)小于大约50g/m2/d，优选是最大30g/m2/d，更优选是最大10g/m2/d。在纸张的制造处理中添加的这些聚合物或聚合物混合物例如是乳胶和各种矿物混合物。The package 2 of the present invention has to fulfill certain requirements related to protection, burst strength, tear resistance, glueability and printability. In addition, packaging 2 must protect the contents of the bag from moisture. Thus, the material of the packaging 2 can, for example, be formed such that the base layer 15 consists of paper to which additives are added in suitable quantities during the manufacturing process by in-line coating in the coating section of the paper machine. Constructed of plastic, polymer blend or similar suitable material 16 that retards moisture vapor absorption in an amount such that the packaging 2 has a water vapor transmission rate (WVTR) (calculated according to ISO 2528:1995) of less than about 50 g/m 2 /d , preferably a maximum of 30 g/m 2 /d, more preferably a maximum of 10 g/m 2 /d. Examples of such polymers or polymer mixtures added during the paper manufacturing process are latex and various mineral mixtures.

根据本发明的一个实施例，形成包1的包装2较光滑，这样，它可以被更容易地涂覆塑料。在这种情况下，包装至少在一侧利用单独的挤出机被涂覆塑料薄膜，这与一些已知方案中相同。由于纸张的光滑性，因此只需要使用比以前更少的塑料。用于该目的的合适塑料薄膜包括聚乙烯(PE)薄膜、聚对苯二甲酸乙二酯(PET)薄膜和聚丙烯(PP)薄膜。According to one embodiment of the invention, the packaging 2 forming the bag 1 is smoother so that it can be more easily coated with plastic. In this case, the package is coated with a plastic film at least on one side using a separate extruder, as in some known solutions. Due to the smoothness of the paper, less plastic needs to be used than before. Suitable plastic films for this purpose include polyethylene (PE) films, polyethylene terephthalate (PET) films and polypropylene (PP) films.

本发明的又一实施例由上述两个实施例的组合来构成。在该方案中，包装2由纸张构成，聚合物混合物在制造过程中在造纸机的涂覆部分中添加在该纸张上，然后，塑料薄膜在单独的挤出机中添加在纸张上。Yet another embodiment of the present invention is constituted by a combination of the above two embodiments. In this solution, the package 2 consists of paper to which the polymer mixture is added during the manufacturing process in the coating section of the paper machine, and then the plastic film is added to the paper in a separate extruder.

包装2的不同层的材料和厚度选择为这样，从而使得上述各本发明实施例的最终结果是在包装中，全部材料层中的塑料的总量占包装2的总重量的小于10％。优选是，塑料的总量为包装2的总重量的最大大约5％。这使得包装对环境友好，并更可回收，同时降低回收成本。The materials and thicknesses of the different layers of the package 2 are chosen such that the end result of the above-described inventive embodiments is a package in which the total amount of plastic in all material layers accounts for less than 10% of the total weight of the package 2 . Preferably, the total amount of plastic is a maximum of about 5% of the total weight of the package 2 . This makes the packaging environmentally friendly and more recyclable, while reducing recycling costs.

图3显示了本发明的一个包装2的层结构，它简化成只显示主要的层。此外，层的厚度并不是按比例的。包装2的基部由基部纸张层15构成。根据纸张的类型，基部纸张层15可以具有一层或多层。图中为了简明而只显示了一层。在纸张层15的顶部是打印墨层14，该打印墨层至少部分地覆盖纸张层15的表面。在纸张层15的另一侧是在纸张的纸张过程中作为在线涂覆而添加的聚合物层，或者是减慢水汽渗透的类似层16。Figure 3 shows the layer structure of a package 2 according to the invention, simplified to show only the main layers. Furthermore, the thicknesses of the layers are not to scale. The base of the package 2 consists of a base paper layer 15 . The base paper layer 15 may have one or more layers depending on the type of paper. Only one layer is shown in the figure for simplicity. On top of the paper layer 15 is a layer of printing ink 14 which at least partially covers the surface of the paper layer 15 . On the other side of the paper layer 15 is a polymer layer added as in-line coating during the paper process of the paper, or a similar layer 16 which slows down the penetration of water vapor.

图4显示了与图3中类似的结构，但是聚合物层或减慢水汽渗透的类似材料层16布置在打印墨层14和纸张层15之间。因此，打印在层16上进行，该层16必须适合打印。此外，基本较薄的塑料薄膜17(例如PE、PET或PP薄膜)在挤出机中已经被添加在包装2上。FIG. 4 shows a structure similar to that in FIG. 3 , but with a layer 16 of a polymer or similar material that slows the penetration of water vapor arranged between a layer 14 of printing ink and a layer 15 of paper. Printing therefore takes place on layer 16 which must be suitable for printing. Furthermore, a substantially thinner plastic film 17 , for example a PE, PET or PP film, has been added to the package 2 in the extruder.

图5显示了本发明的第三包装2的层结构，它简化成只显示主要的层。此外，层的厚度并不按比例。该层结构与图3中的类似。在该结构中，表面层18添加在基部纸张层15的顶部，该表面层可以利用热量或超声波而被熔合。在这种情况下，不使用单独的胶水，通常胶接的所有接缝都可以通过热封或超声波而形成。打印墨层14不能越过将被熔合的接缝。Figure 5 shows the layer structure of the third package 2 of the invention, simplified to show only the main layers. Furthermore, the thicknesses of layers are not to scale. The layer structure is similar to that in FIG. 3 . In this construction, a surface layer 18 is added on top of the base paper layer 15, which may be fused using heat or ultrasound. In this case, instead of using a separate glue, all seams that are usually glued can be formed by heat sealing or ultrasound. The ink layer 14 cannot pass over the seam to be fused.

包装2的分层和(特别是)厚度可以用于调节在包1内部的纸张捆怎样抵抗来自外部的击打和冲击。至少包装2的厚度是这样，即包装的重量在60-250/m2的范围内。根据包装材料，合适的厚度范围(表示为重量)是80-160g/m2。该厚度也可以设置为使得重量是120-150g/m2。The layering and (in particular) thickness of the package 2 can be used to adjust how the bundle of papers inside the package 1 resists knocks and impacts from the outside. At least the thickness of the package 2 is such that the weight of the package is in the range of 60-250/ m2 . Depending on the packaging material, a suitable thickness range (expressed as weight) is 80-160 g/m 2 . The thickness can also be set such that the weight is 120-150 g/m 2 .

本领域技术人员应当知道，本发明并不局限于上述实例，而是可以在后面的专利权利要求的范围内变化。保护包装并不必须来自于用于保护包装的卷材，而是可以为切割好的片材。It is clear to a person skilled in the art that the invention is not limited to the examples described above, but that it may vary within the scope of the following patent claims. The protective packaging does not have to be from the roll material used for the protective packaging, but can be a cut sheet.

而且，本领域技术人员应当知道，环绕包的保护包装的包装材料可以以多种不同方式来形成，只要能够在包的端部处进行折片胶接。Furthermore, those skilled in the art will appreciate that the wrapping material surrounding the protective wrapping of the bag can be formed in many different ways so long as the flap bonding at the ends of the bag is enabled.

而且，本领域技术人员应当知道，可以使用除上面所述的其它类型的保护结构来代替该包装。例如，根据本发明的方案，可以使用由无纺织物或其它类似的薄保护材料构成的包装。Furthermore, those skilled in the art will appreciate that other types of protective structures than those described above may be used in place of the packaging. For example, according to the aspects of the present invention, packages made of non-woven fabric or other similar thin protective materials can be used.

本领域技术人员还应当知道，如果在纸张制造时例如将使得材料具有合适憎水性的物质添加在纸张层上，则包装材料并不必须包含任何塑料。A person skilled in the art will also be aware that the packaging material does not necessarily contain any plastic, if during paper manufacture eg a substance which makes the material suitably hydrophobic is added to the paper layer.

而且，本领域技术人员应当知道，纸张的尺寸可以与上述A4尺寸不同。纸张可以比A4纸张大、小或具有不同的形状。Also, those skilled in the art will appreciate that the size of the paper may be different from the above-mentioned A4 size. Paper can be larger, smaller or have a different shape than A4 paper.

而且，本领域的技术人员应当知道，在包中的纸张数目可以与100-400或大约250张的推荐量不同。该数目可以更大或更小，或者甚至与令包装中的(大约500张)相同。Also, those skilled in the art will appreciate that the number of sheets in a pack may vary from the recommended amount of 100-400 or approximately 250 sheets. This number can be larger or smaller, or even the same as in the ream package (approximately 500 sheets).
