Description

Detailed description

  The present invention relates to a collective package for sheet materials such as printing paper and copy paper described in the first stage of claim 1, and a collective package described in the first stage of claim 11 and used in connection with the collective package. It is related with the method of manufacturing.

  In a known technique, office paper such as A4 copy paper and printing paper supplied in sheet form is usually packaged in a cardboard box, and each box has five paper bundles wrapped in individual wrapping paper. Yes. Each bundle of paper known as continuous wrapping contains 500 sheets of A4 size paper. Corrugated boxes provide good protection for office paper during transport, but are problematic because of their cost and because they take up space in an empty box until processed or recycled. In addition, the box has a lid and is actually bound by a thin plastic strip that also functions as a carrying handle. The problem with the use of plastic strips lies in the processing method, and because of the weight of the five continuous packs in the box, thin plastic strips are very uneasy to transport the box.

  To address these shortcomings, other collective packaging schemes have been developed for office paper. Packages are made, for example, from various wrapping papers that wrap around a continuous package. The challenge with these types of packaging materials is how to make a package that can withstand the impacts that can occur during transportation and storage. In addition, the package needs to protect the paper inside the continuous wrap from moisture. Important strength properties of the packaging material are pull-out resistance, tensile strain and burst strength. There are known types of paper that meet these strength criteria, which are fairly sufficient for use as packaging materials, for example in assembled continuous packaging packages. The problem is that these types of paper do not provide sufficient protection against moisture. Therefore, in the prior art, the packaging material is coated with a moisture-proof plastic layer. In addition, the plastic layer further enhances the strength properties of the packaging material. The plastic layer can be made, for example, of PE, PET or similar film applied to the paper in a separate extruder.

  The problem with plastic coated packaging materials is that due to their plastic content, they are not as environmentally friendly as those without plastic. Furthermore, the recycling costs of plastic-coated wrapping paper according to the prior art are considerably higher than wrapping paper without plastic in most countries. Plastic coating has the additional problem of requiring a separate extruder and work step, which increases costs and takes time.

  An object of the present invention is to solve the above-mentioned problems and to achieve, in a possible range, an inexpensive collective package for office paper that protects paper well even if plastic is used to some extent. In addition, an object is to make a collective package that is easy to transport and has a weight that is evenly distributed in both hands, for example. It is another object of the present invention to achieve an affordable, quick and reliable method for manufacturing packaging materials for collective office paper bundles and collective packages themselves. The collective package according to the present invention is characterized by the matters disclosed in the characteristic stage of claim 1. Similarly, the method according to the invention is characterized by what is disclosed in the characterizing part of claim 11. Other embodiments of the invention are characterized by what is disclosed in the other claims.

  The advantage of the scheme according to the invention is that the collective package according to the invention can be manufactured very cheaply and quickly. Another advantage is that the packaging material has a high resistance to bursting and tearing, and the collective package provides good protection for the bundle of paper that is inside and wrapped in the respective wrapping paper. A further advantage is that the collective package and the continuous packaging inside it can be made of the same paper material. Another advantage is that according to the present invention, it is easy to lift the collective package using both hands, whereby the load is evenly distributed between both hands. By properly carrying the handle or the same device, the weight is not given to the hand as the plastic band conventionally used. A further advantage is that the packaging material is available in reel form, thereby minimizing waste. It is also a further advantage that the packaging material uses little or no plastic, which makes it environmentally friendly and inexpensive to recycle. Another advantage is that the packaging material is highly resistant to moisture even if it does not have a separate plastic layer. Similarly, if a wrapping paper coated with an appropriate layer is used, it is easy to fuse the seam using heat sealing or ultrasound. Another advantage is that the wrapping paper is provided with at least one strip, which makes it easier to open the package. A further advantage of a collective package with an opening strip is that once opened, the empty package can be used as a bag suitable for other folded packages or other materials that are sent for recycling. A further advantage is that the opening strip is arranged at an appropriate distance from the end of the collective package so that when the collective package is opened, the end of each bundle in the collective package is easy to see and take out. is there.

  Next, the present invention will be described in detail with reference to the accompanying drawings using application examples.

  1 and 2 show a collective package 1 according to the invention. The office paper bundle 1a is, for example, the size of continuous wrapping, which is packed with A4-size sheet paper, but packed into a collective package 1 that forms a protective package made of a strong protective packaging material. Yes. Each paper bundle 1a is further wrapped in a paper-like wrapping paper 2a. This collective package is made from reel-type wrapping paper, and is drawn directly from the reel during packaging and cut to the correct length, and then the protective wrapping paper 2 is individually stacked, for example, in groups of five. Wrap around a bundle of paper 1a, the top, bottom and both long sides of the collective package form one continuous wrapping, with the back 22 of the protective wrapping paper 2 in the proper amount at the front edge of the wrapping paper And paste the inner surface to the outer surface of the front end. Although the hidden front end of the wrapping paper 2 is shown here, it is shown using broken lines in other figures. The rear end 22 of the wrapping paper 2 is located near the top surface of the collective package, substantially one of its long corners. At each end of the collective package, there are at least outer folding portions 3 and 4 and inner folding portions 5 and 6, and each folding portion is arranged so that at least a part thereof overlaps. The folds at both ends serve to reinforce the protection of the edge of the office sheet in the package that could damage multiple sheets even in small accidents.

  In the collective package of FIG. 1, the outer folding portions 3 and 4 at both ends of the collective package are bonded to each other using, for example, thermal bonding, and are adhered to at least the outer surface of the upper inner folding portion 5 to at least the outer folding portion 3. And the lower edges of 4 are separated from the outer surfaces of the inner folds 5 and 6. Accordingly, a lifting gap 7 that opens downward remains between the outer folding parts 3 and 4 and the inner folding parts 5 and 6, and this gap spreads outward from the end of the collective package 1, A person lifting the package can put several fingers into the lifting gap 7 from below, and the lower edges of the outer folding parts 3 and 4 can serve as a support.

  Also shown in FIG. 1 is a wrapping strip 23 in broken lines, which adheres to the inner surface of the protective wrapping paper 2 before cutting the wrapping paper. Accordingly, the unwrapping strip 23 is substantially the same length as the protective wrap 2 or longer than appropriate. The opening strip 23 is located at an appropriate horizontal distance from the end of the collective package 1. The appropriate distance is, for example, 1 to 4 cm, and as shown in FIG. 2, before the protective wrapping paper 2 is opened, the paper continuous wrapping 1a in the collective package 1 can be appropriately visually confirmed. deep. For this reason, it becomes easy to extract the continuous packaging 1a from the collective package. At the end of the unwrapping strip 23, the edge of the protective wrapping paper 2 is cut along the end 22 of the protective wrapping paper 2 and along the unwrapping strip 23 on each side of the unwrapping strip 23. In this way, a notch 24 having an appropriate length is provided in the length direction. As a result, the end portion of the unwrapping strip 23 can be easily grasped, and the protective wrapping paper 2 can be cut and opened just around the collective package 1. The material of the unwrapping strip 23 can vary, but this should always be sufficiently strong and substantially inelastic or slightly elastic. The unwrapping strip 23 is hidden inside the protective wrapping paper 2, but is shown using a broken line in FIG. On the other hand, in another view, the unwrapping strip 23 is visible, which is only the end of the unwrapping strip 23 and is provided with a notch 24.

  FIG. 2 shows a collective package 1 according to the present invention, which is unwrapped at the end of the unwrapping strip 23, the top paper stack 1a has already been extracted and the second stack 1a is Somewhat drawn from the collective package 1.

  FIG. 3 shows an embodiment of the method according to the invention for producing a collective package 1 according to the invention. The beginning of the work cycle is a state where the products to be packed together as a collective package are arranged and ready to make a collective package, that is, for example, a plurality of paper bundles 1a are in a pile of five continuous packages. Good. The width of the wrapping paper forming the protective wrapping body 2 according to the present invention is designed to be longer than the length of the paper bundle 1a by a desired amount. The wrapping paper forming the protective wrapping body 2 is taken out directly from the reel and pulled out along its width so as to be the bottom of the paper bundle 1a. At first, the wrapping paper 2 is wrapped around the paper bundle 1a to be wrapped, and the rear end portion of the protective wrapping paper is overlapped with the front end portion of the protective wrapping paper on at least one side of the long side of the collective package 1. The rear end portion of the protective wrapping paper is optimally arranged at the edge between the two long ends, for example, the edge between the top surface and the front surface as shown in FIG. In the figure, the right side of the collective package is the front.

  When the reel-type protective wrapping paper is cut to a correct length and the paper bundle 1a is wrapped, the upper folded portion 5 is pressed downward against the end portion of the collective package 1 to form an end folded portion. Similarly, the lower inner folded portion 6 is pressed upward against the end portion of the collective package 1. After the inner folds 5 and 6 are pressed against the end of the collective package, both portions of the protective wrapping paper 2 exceeding the length of the paper bundle are folded at the vertical end so that they overlap at the apex of each other. The outer folds 3 and 4 are made simultaneously by doing this, ie by making substantially two triangular folds. In order to ensure that the outer folding parts 3 and 4 overlap at the final position, the length of the protective wrapping paper that exceeds the length of the paper bundle on both sides of the collective package must be at least half the width of the paper bundle. is there. The length here refers to, for example, the longer edge of A4 sheet, and the width refers to the shorter edge. After making the folds, the outer folds 3 and 4 are glued to each end of the collective package 1 to at least one of the inner folds 5 and 6 and to each other if necessary.

  In a package without a carrying handle, the outer folding parts 3 and 4 are bonded to each end of the collective package to form a lifting gap 7 that enables the collective package 1 to be transported and lifted. The lower edge of the lifting gap 7 serves as a support for lifting and transportation.

  In the manner shown in FIG. 3, the substantially horizontal adhesive seam that acts as the adhesive seam 8 is near the lower edge of the inner fold at the outer surface of the upper inner fold 5 and substantially at the full width of the fold 5. Extending along. Similarly, a substantially vertical adhesive seam serving as an adhesion seam 9 extends on the inner surface of the outer fold 4 and near the outer end of the fold 4. After extending the adhesive, the outer folding part 3 is continuously pressed against the inner folding parts 5 and 6 inside, and then the uppermost folding part 4 is moved to the other outer folding part 3 and the inner folding parts 5 and 6. Press against. As a result, the collective package according to FIG. 1 is formed, but a lifting gap 7 for lifting and carrying the collective package remains at the lower edges of the outer folding parts 3 and 4. According to this bonding method, there is a similar lifting gap at the upper edge of the outer folding portions 3 and 4, which means that it can be lifted even when the collective package is upside down. Yes.

  FIG. 4 shows another bonding method which is also included in the concept of the present invention. In this method, the innermost outer folding part 3 is bent and then the inner surface thereof is bonded to the outer surface of the inner folding part 5. At this time, the adhesive seam acts as an adhesion seam 10, which is substantially It is close to the upper edge of the folded part 3 and is located in parallel therewith. Similarly, the outermost outer fold 4 folds over the outer fold 3, which, after folding, is another adhesive seam that acts as an adhesive seam 11 and an extension of the other adhesive seam. Two adhesive seams 12 are used to adhere to the outer surfaces of the inner folding part 5 and the outer folding part 3. This bonding method leaves the lifting gap 7 only at the lower edges of the outer folds 3 and 4, so it must be oriented correctly before lifting the collective package.

  FIG. 5 shows a method of lifting and carrying the collective package created by the above method by the lower edges of the outer folding portions 3 and 4, and the fingers are moved by the lifting gap 7 to the outer folding portions 3 and 4 and the inner folding portion 5. And 6 can be inserted. Since there are adhesive seams 8 and 9 or 10 to 12, the protective packaging 2 of the collective package can withstand the lifting and carrying of the package.

6 to 8 show some typical layer systems for protective wrapping paper according to the present invention. At least one of the wrapping paper forming the protective wrapping body 2 according to the present invention and the wrapping paper 2a of the paper bundle 1a, or these wrapping papers, relates to at least protective suitability, rupture strength, tear resistance, adhesion and printability. It is necessary to satisfy certain conditions. In addition, the wrapping paper forming the protective wrapping body 2 and / or the wrapping paper 2a of the paper bundle 1a needs to protect the contents of the package from moisture. In an advantageous embodiment of the invention, the protective wrapping paper 2 and the wrapping paper 2a of the paper bundle 1a are hydrophobic, ie water-repellent. Therefore, the packaging material for forming the protective packaging body 2 of the collective package 1 and the packaging paper 2a for wrapping the paper bundle 1a can be formed as follows, for example. That is, the base layer 19 of the protective wrapping paper 2 and the base layer 19a of the wrapping paper 2a for wrapping the paper bundle are made of paper, and during manufacturing, an additive is added as an online coating at the coating processing section of the paper machine. The adduct has a total water vapor transmission rate (WVTR) of about 50 g / m ² / d between protective wrap 2 and wrap 2a calculated according to ISO standard 2528: 1995, preferably up to about 30 g / m It consists of a suitable amount of plastic, polymer mixture or similar suitable material 20 that delays moisture absorption, which is less than ² / d, preferably up to 10 g / m ² / d. Such polymers or polymer blends added during the paper production process are, for example, latex compounds and various inorganic compounds.

  According to an embodiment of the present invention, the wrapping paper forming the protective package 2 and / or the wrapping paper 2a of the paper bundle is smooth and can be more easily coated with plastic. In this case, these wrapping papers are coated with a plastic film on at least one side using a separate extruder, as is done in several known ways. Because paper is smooth, it is necessary to use less plastic than before. Suitable plastic films for this purpose include polyethylene (PE) films, polyethylene terephthalate (PET) films, and polypropylene (PP) films.

  Another embodiment of the invention consists of a combination of the two embodiments. In this method, the wrapping paper for the protective packaging 2 and the wrapping paper 2a for the paper bundle 1a are made of paper, and during production, a polymer mixture or similar material is added to the coating section of the paper machine, and then the paper In contrast, the plastic film is applied in a separate extruder.

  The end result in each of the three embodiments of the present invention described above is the protective wrapping paper 2 of the collective package 1 and the wrapping paper 2a of the paper bundle 1a, and the total amount of plastic is substantially the sum of these wrapping papers. Less than 10% of weight. Advantageously, the total amount of plastic is at most about 10% of the total weight of the protective wrapping paper 2 and the paper bundle wrapping paper 2a. As a result, the protective wrapping paper and the continuous wrapping paper are environmentally friendly and can be recycled with low recycling costs.

  FIG. 6 shows the layer structure of the protective wrapping paper 2 and the paper bundle 1a wrapping paper 2a according to the present invention, but only the necessary layers are shown in a simplified manner. Note that the thickness of these layers is not shown. The bases of the wrapping papers 2 and 2a are formed by paper base layers 19 and 19a, or simply by paper layers 19 and 19a. Depending on the type of paper, the paper layers 19, 19a can be one or more layers. In the figure, only one layer is shown for simplicity. On top of the paper layers 19, 19a is a printing ink layer 18, which at least partially covers the surface of the paper layers 19, 19a. On the other side of the paper layers 19, 19a is added a polymer layer or similar layer 20 that delays the permeation of moisture as an on-line coating during paper production.

  FIG. 7 shows the same structure as in FIG. 6, but a polymer layer or similar material 20 that retards the permeation of moisture is disposed between the printing ink layer 18 and the paper layer 19. Thus, printing is performed on layer 20, but this layer must be suitable for printing. A substantially thin plastic film 25 such as a PE film, a PET film, or a PP film is added to the wrapping paper 2 by an extruder.

  FIG. 8 shows the layer structure of the third embodiment of the protective wrapping paper 2 and / or the wrapping paper 2a for the paper bundle 1a according to the present invention, but only the necessary layers are shown in a simplified manner. Note that the thickness of these layers is not shown. This layer structure is the same as that in FIG. In this structure, a surface layer 21 is added to the upper surfaces of the paper base layers 19 and 19a, and the surface layer can be welded using heat or ultrasonic waves. In this case, all the above-mentioned bonded seams can be welded by heat sealing or ultrasonic waves without using a separate adhesive. The printing ink layer 18 need not extend beyond the seam to be welded.

  In all the layer structures in the above embodiment, and in all other layer structures according to the present invention not shown in the accompanying figures, the material and thickness of the wrapping paper is that the total amount of plastic in the various layers is protective packaging The total weight of the paper 2 and the wrapping paper 2a of the paper bundle 1a is selected to be at most 10%, preferably at most 5%.

By using the layering of the wrapping paper 2a of the protective wrapping paper 2 and the paper bundle 1a, in particular, the thickness, resistance to impact and impact from the outside of the paper bundle inside the collective package 1 can be adjusted. At least the thickness of the protective wrap 2, the weight of the packaging it is necessary to be within a range of 60 to 250 g / m ^2. Depending on the packaging material, a suitable thickness range is 80-160 g / m ² expressed in weight. This thickness may suitably be such that the weight is between 120 and 150 g / m ² .

  In order for the protective wrap 2 to withstand handling of the collective package, the packaging material should have a suitable burst strength and tear resistance of at least 1200 mN, preferably even higher. Similarly, the adhesiveness of the adhesive must be at least 15 Denison.

  9 to 12 show various types of methods for carrying the collective package 1 according to the present invention. The collective package can be lifted using both hands at both ends of the package as described above, but sometimes it is easier to handle the package using a carrying handle made for a special purpose. Also, sometimes it is necessary to handle the package with only one hand.

  FIG. 9 shows a collective package 1 according to the invention, with a separate carrying handle at each end of the package. A strip-type appropriately reinforced carrying handle 13 is bonded between the outer folds 3 and 4 and the inner folds 5 and 6 at each end of the package.

  Similarly, FIG. 10 shows a collective package 1 according to the invention, with individual carrying handles on the top surface of the package. The carrying handle 14 is made, for example, of fiber reinforced laminate paper and glued to each end of the collective package 1, eg an adhesive seam between the inside of the handle and all the end folds 3-6 of the package. Is arranged. The carrying handle 14 can be adhered to the upper surface of the collective package 1 along a short distance at both ends of the package. This provides a durable and easy-to-use carrying handle system.

  FIG. 11 shows a handle system similar to the system in FIG. 10, but in this embodiment, the strip-type carrying handle 15 is arranged so as to cross the collective package 1 in the lateral direction, and is adhered to both side surfaces of the package. Has been. To increase durability, the carrying handle 15 can be adhered to the wrapping paper on the top surface of the package along a short distance starting from the top edge of the package.

  The carrying handles 14 and 15 shown in FIGS. 10 and 11 can surround the entire collective package 1 and can be adhered to the bottom of the package, for example, to make the handles invisible. In such a case, the carrying handle also supports the load. This is because the wrapping paper that forms the protective packaging 2 is bonded to the wrapping paper, or the package is folded at the end of the wrapping paper. It means that it can be thinner than the one used in the method of lifting by part.

  FIG. 12 shows a method of carrying handles in which strip-type handles 16 are arranged so as to cross the collective package 1 in the lateral direction and are bonded to both ends of the upper surface of the package. The adhering matter is reinforced by a reinforcing tag 17, and this tag has a hole through which the carrying handle 16 is passed in the center. The reinforcing tag 17 is adhered to the upper surface of the collective package and covers both ends of the carrying handle 16.

  It will be apparent to those skilled in the art that the present invention is not limited to the above-described embodiments, but can be modified within the scope of the following claims. Therefore, it is not necessary to take out the protective wrapping paper from the reel for production of the collective package, and a cut sheet may be used.

  Furthermore, it will be apparent to those skilled in the art that the protective wrapping paper that wraps the package can be packaged in many different ways so that the folds can be bonded at both ends of the collective package.

  It will also be appreciated by those skilled in the art that various carrying handles different from those described above can be attached to the collective package according to the present invention. For example, separate reinforced strips can be used in the same way as commonly applied plastic strips to wrap the collective package. Regardless of the width of the band, handling of the collective package becomes comfortable. In this scheme, the protective wrapping paper can be thinner and weaker than the scheme described above. This is because the wrapping paper itself cannot withstand any load when lifting or transporting the collective package. The carrying handle can be paper and / or plastic.

  Furthermore, those skilled in the art will appreciate that other types of protective structures other than those described above can be used instead of the package. For example, wrapping paper made of non-woven fabric or other similar thin protective material can be used in the system according to the invention.

  Furthermore, those skilled in the art will appreciate that the collective package according to the present invention is suitable for many types of packages other than five separate bundles of collective packages. For example, two to five paper bundles can be wrapped together to form one collective package.

  Furthermore, those skilled in the art will appreciate that the thickness and weight of the paper used for the protective wrapping paper can be different from that described above.

  Furthermore, it will be apparent to those skilled in the art that the collective package can be constructed of corrugated cardboard or similar material rather than a paper-based protective wrapping paper. In this case, it is necessary to select the water vapor transmission rate so that the protective wrapping paper and the wrapping paper of the paper bundle to be put together with it become an appropriate barrier.

  It will also be appreciated by those skilled in the art that the packaging material need not contain any plastic if a material that renders the material sufficiently hydrophobic is added during paper production, for example to the paper base layer.

  It will also be appreciated by those skilled in the art that sheet paper can be packaged with more protective layers than the two layers described above formed by a bundle of paper and a protective wrapping paper or protective box for a collective package. For example, three, four, or more protective layers are possible. A single protective layer is sufficient if its strength and water repellency are sufficiently good.
