Description

This invention relates to a paper bag with a jel device) and in particular to a paper bag with a jel device where the carry device is in the form of an extension of the top of the bag; So that this upper part closes before filling the bag from the bottom with a specific amount of goods. After filling, the bottom of the bag is also closed. expand. The spread of paper bags equipped with a die carrying method, the double handle added, Call a, and in most cases these bags are Jie with a gle hole, although some may be provided with an extension that can be folded when filling the bag. Mostly, these bags are traded by the owners of pad shops for customers to use to carry their personal goods. These bags are not suitable 0 for packing and sealing goods that are sold in specific quantities, pre-packed. In order to solve this problem, paper bags with a carrying hole were developed that may have been reinforced on opposite sides near the edges of the open end pall so that the open end would be closed after filling; Ka by sewing, stitching or gluing it across the full width of the bag under the carrying opening; To extract the contents of the bag, this closed part is cut. Such bags are used for 1 pet food and as a cradle for cats; to other uses; However, these bags have disadvantages, including 1: Once opened, it is not possible to carry them easily from the carrying slots. In addition, the 0 closed-filled bag does not represent a typical space-saving shape because the CL-packed product tends to slack down so that the portion of the extension containing the carrying hole remains upright over the slack bag. 0 UK Patent No. 44,774,908 describes a package consisting of a paper bag comprising .ye materials stacked compactly inside the package with a dis opening device, with a Cua (Jan) device The carrying device is formed by an extension of the top plate of the package. One drawback, however, is The method of carrying described is that in order to avoid raw edges which might make carrying the bag uncomfortable, it is necessary to slide a protective member over the free upper edges of the means of carrying, for example by means of a sewing line.This would make the bag more expensive because it means not only additional materials but steps Additional manufacturing as well which means more equipment and more gl for z lam

A | Figure (17) shows the completed upper part of a paper bag with a carrying device according to a third embodiment of this invention. The carrying hole (VA) is perforated via extensions (1b) (MAY a) and through a stiffener (Yo ) This perforation can be done after assembling these extensions and can also be done separately on each of these extensions and in the stiffening bracket before assembling. First, as in promotional sales, for example. This assembly can be done by any conventional means such as gluing, stitching, or sewing. 'Paper bags with integrated carry-on according to this invention can be made with different grades of paper. It turns out that paper or layers of assembled paper With a basic total weight ranging from 21 to 175 grams per square meter, it is suitable for the purpose.However, the types of paper that provide the best characteristics from the environmental point of view for making the bag with the integrated means of carrying according to this invention are the types of raw unbleached paper or types of recycled paper Lad Unbleached Manufacture It is necessary, in order to present an attractive package made of unbleached paper, to coat the outer surface of this paper in white so that good quality printing can be made on it. Experience has shown that ve-aS opaque wrapping of unbleached paper causes problems because this UW paper must be made of light-colored fibers such as unbleached mechanical wood pulp and/or must be coated with a layer of gram-weight paper higher. Neither of these two solutions is adequate because they lack the good mechanical properties required for packaging compressed commodities in a paper bag. For these reasons, the best results are achieved with two-layer paper, the first of which is made of non-Yo kraft paper pulp, bleached brown in color, with mechanical properties Bua, and the second is made of wood pulp / light brown paper, not bleached Co. And as it is known to the person skilled in this field, such as 13a paper consisting of two layers can be made either with a paper making machine with two screens or more so that the layer of kraft pulp in the final product is on the inside of the bag and the layer of mechanical wood pulp is on the outside of the bag. Another solution is to make each of the two layers separately and then paste them together to form a group of layers. It was found that paper made of several layers bonded together with glue achieves the best technical properties required for packing, for example packing compressed materials that are used for one time, while maintaining the desired environmental properties at the same time. z 0 m i 2

: : 1 To obtain a good printable surface on the finished bag if desired the light brown unbleached layer of wood pulp/paper SS can be coated with a white layer of low gram weight. Another precaution is to use a type of bleached paper with optimal environmental properties; Like bleached paper (partially oxygenated). If such an oo type of Gs is used then an outer white layer is not needed to achieve a good quality foundation -ell As for the stiffeners any kind of biodegradable and/or easily recyclable material can be used. to be appropriate; These materials may include paper, cotton fabric, or both together, as well as other materials. 1 wherever reference is made to fixing extensions, panels or strips; This installation can be done in any suitable way, whether by gluing or thermally gluing the appropriate coating layers that are placed during the printing steps on the raw paper sheets. However, it is highly recommended that the adhesive or thermal adhesive varnish used be of a biodegradable composition. 0 In view of the fact that the invention is directed to means of carrying integrated with paper bags, only the upper parts only have been clarified. of those bags. It is preferable that these bags be equipped with means of opening and emptying that remain on the means of carrying intact whenever it is necessary to extract the contents of the bag. One of the most convenient means of opening is what was mentioned in the British patent application No. 0 Plugel | 0 J Although the completion of the first step in the LS bag forming process is described in Figure 0 (1) x. An overlapping bracket (0) is fixed to the loose end of the main plate (1); CSE enables the tubular cavity of the bag by dividing the forming sheet in such a way that the overlapping slide that is attached to it can be placed to form the tubular cavity of the bag in another place.The advantage of placing it as described in a (Y) shape is that a completely smooth side plate is obtained, which facilitates printing It appears to the person skilled in the art that the integral carrying means shown in the three preferred embodiments mentioned above can easily be folded onto the top surface of the filled paper bag for shipping and storage purposes and that they can easily be retrieved when needed. Her position for carrying Z 1 m

Yes, it is known that paper bags with an integrated carrying method according to this invention are very useful in packing materials such as disposable diapers, although their use is not limited to this type of content. Up to now, disposable nappies have been packed mostly in plastic bags or in cardboard boxes for smaller quantities. It is known that plastic bags © are not subject to biodegradation, and so far they are not easily recyclable. Thus, a great advantage is achieved if it becomes possible to package single-use materials in a paper bag. The integrated carry-on paper bag according to this invention can be filled using the packing machines used, Wa | to fill the carry-on bags, with very slight modification to these machines. In addition, the crease lines shown in the above examples can be easily replaced with 0 scratch lines originally formed on the raw paper sheet, which would improve the process of folding and ribbing the paper bag during its formation. It will clearly appear to those skilled in this art a possibility. Make several modifications to the described invention. Examples of some of these modifications are mentioned above. Accordingly, the scope of this invention must be taken into account in light of the following protection elements, provided that it is understood that it is not limited to 1 the details or configurations described and illustrated by the specifications and drawings: A L Z. 11
