Description

The present invention is particularly ideal for packaging, transporting and handling solid powder materials and / or bulk materials, especially made from polymeric materials, with removable covers that allow the packaging to be opened for reuse. Regarding bag-shaped or large bag-shaped packaging.

Bag-shaped or large bag-shaped packaging made of polymer materials has been known for decades and various products, especially soil, fertilizer, grains, sugar, coffee, flour, animal feeds, polyvinyl chloride compounds, Widely used for packaging especially solid powder materials and / or bulk materials such as cement.

Generally, bags or large bags consist of polymer materials based on low density polypropylene, polyethylene and additives, but other materials are also used. The material for making this type of sachet is called raffia and contains the flat twisted yarn produced by extrusion used in the production of polymer fabrics.

Raffia packaging consists of various flat plyings with a width of several millimeters, manufactured by the extrusion process of polymers such as polypropylene or polyethylene, or other fibers or fiber mixtures. These raffia plying yarns are driven, pulled, wound around a core and then woven into a polymer fabric. These fabrics are usually divided into flat fabrics and tubular fabrics.

In addition to providing safety and ensuring product integrity, the main attraction of this Raffia packaging is the reuse of the packaging, that is, after use, the packaging produces no waste. Reused for other purposes, such as bagging supplies, disposal of debris in construction work and other uses.

More resistant and stronger, Raffia guarantees effective protection against the effects of moisture, dirt and rodents, which is an important property for preserving food. Another advantage is the economics brought about by materials that can be reused, reducing losses in transit, which allows Raffia to be used without further environmental damage due to its low environmental impact. Make it a thing.

Bags are separated by type of closure and can be sewn or soldered and may include an upper or lower valve that serves as a place to fill the bag. Since the product can be packaged by a filling valve, but cannot be pulled out of the package by the valve, handling of the bagged product at the time of consumption is usually done by cutting the body or bag cover.

The latest technology in bags or large bags made by Raffia seeks to offer a solution in the sense that it provides support and reinforcement, especially in the closed parts of the bag, and has developed a technology that can efficiently close these bags. Demonstrate the need to do.

German Patent No. 2009007915 and Brazilian Patent No. PI9507701-4 disclose materials and methods for closing a package, whether made of paper or polymer material. It provides the reinforcement and resistance needed to maintain packaging integrity in the transportation and handling of heavy goods.

In addition to the need to close raffia bags efficiently, state-of-the-art solutions have been found to easily open these bags, especially when using bagged products. ..

China Practical Innovation No. 2095841 and International Publication No. 2013/123015 pamphlets provide solutions for opening packages made of both paper and polymer materials and bags for the use of the product. Discloses creases or cutting lines that can improve the opening of the package. It should be noted that using either the easy-to-open creases or the weakening lines to easily cut the bag or large bag will always result in a more fragile or more vulnerable package, as there is less resistance when opening. ..

Therefore, considering the need for reinforced closures and the possibility of opening the bag, it only provides the safety and resistance guarantees necessary for the transportation and handling of packages made of polymer materials and loaded. Instead, bag-shaped or large bag-shaped packages have been developed with removable covers that allow the packages to be opened for reuse.

The present invention is ideal for packing, transporting and handling a variety of products, especially solid powder materials and / or bulk materials such as soil, fertilizers, grains, sugar, coffee, flour, animal feeds, polyvinyl chloride compounds, cement. The present invention relates to a typical bag-shaped or large bag-shaped package 1.

First, it should be noted that the packaging 1 of the present invention is a bag or large bag made of a polymeric material such as polypropylene, polyethylene and derivatives thereof, for example raffia, without limiting the use of other materials. is important.

The packaging 1 of the present invention preferably includes a closure by an adhesive means such as an adhesive or solder, and a valve that acts as a portion for filling the bag. In an alternative configuration, packaging 1 includes a closure by adhesive means without a filling valve 6.

Currently, raffia bags, with or without valves, provide the reinforcement and resistance needed for safe transportation and handling of the bag during loading, as well as reusing the bag. Other than the main purpose, there is no removable cover 5 that allows the large bag to be further opened by removing the cover 5 without making cuts or crevices.

Accordingly, it additionally provides great reinforcement and resistance in fixing the removable cover 5 to ensure the integrity of the packaging 1 even for heavy objects weighing over 40 kg, 50 kg, 60 kg, 100 kg or 200 kg. Various studies have been conducted to develop a package 1 in which the cover that prompts the opening of the package 1 can be removed for filling and reuse.

The main and innovative differentiator of the present invention is not the type of body or material used in the packaging 1 itself, but rather the basis weight and density of the removable cover 5, and the removable cover 5 is fixed to the body. This allows for the above resistance and removable possibilities.

The bag-shaped or large bag-shaped package 1 which is the object of the present invention includes a main body 2 made of a polymer material, preferably a polymer cloth such as a raffia made of polypropylene or polyethylene. Even if raffia is the preferred material, it is possible to devise packaging 1 depending on the scope of protection, including materials consisting of other types of fibers or mixtures of fibers. Further, the package 1 can be made of a non-woven fabric material made of any kind of fiber or a mixture of fibers. Further, since the material can be composed of not only fibers but also a polymer film such as a polyethylene film, the scope of protection of the present invention is not limited by the material constituting the package 1.

As shown in FIG. 1, the main body 2 of the package 1 has a first end portion 3 forming the first surface 3'and a second surface 4'on the opposite side of the first end portion 3. Includes a second end 4 to form.

Preferably, the first end 3 corresponds to the inlet or filling of the packaging 1, where the filling valve 6 may or may not be provided, the second end 4 of the packaging 1. Corresponds and should be considered as a bottom and / or adjoining part.

Packaging 1 further comprises a substantially flat removable cover 5 that defines a third surface 5', wherein the removable cover 5 has a third surface 5'and a second surface 3'and / or a third surface. Contact with 4'is associated with at least one of the ends 3 and 4, and it is possible to open at least one of the ends 3 and 4 by removing the cover 5. FIG. 3 shows a third surface 5'and a second surface 4', with the removable cover 5 already pulled out of the packaging.

Preferably, although not essential, the removable cover 5 preferably comprises a substantially rectangular portion made of the same material as the body 2. In another configuration, the removable cover 5 is made of a different polymer material than the constituent material of the body 2. Further, the removable cover 5 has a different basis weight and density than the main body 2. The present invention is capable of functioning at any basis weight (lower, equal or higher) than the basis weight of the body 2. In any case, the preferred configuration utilizes the basis weight of the removable cover 5, which is higher than the basis weight of the main body 2. The same logic applies to the density of the removable cover 5 as compared to the body 2.

The removable cover 5 is associated with at least one of the ends 3 and 4 by an adhesive means such as solder or adhesive, and the entire closed fold of the ends 3 and 4 varies depending on the length of the fold of the package 1. It extends along.

Preferably the removable cover 5 includes a size larger (width and / or length) than the size of the ends 3 and 4, eg, the removable cover 5 is removable, as shown in FIGS. 1 and 2. Protrusions are defined on one or more sides of the removable cover 5 for ease. In an alternative configuration, the removable cover 5 includes the same size as the ends 3 and 4 without defining side, top or bottom protrusions.

The removable cover 5 of the present invention is associated with a first end 3 and / or a second end 4, depending on the type of bag.

As described above, the large bags found on the market may or may not include a filling valve 6 that facilitates the product filling process.

In the case of a large bag that does not include a filling valve 6 and is closed after filling, the large bag includes an open first end 3 and a removable cover 5 is associated with a second end 4.

Regardless of whether the filling valve 6 is provided at the first end 3 or the second end 4, in the case of a valved bag (with the filling valve 6), the removable cover 5 is , Package 1 is associated with at least one of the ends 3 and 4 so as to include the removable cover 5 provided at the first end 3 and / or the second end 4. In other words, the removable cover 5 can be placed at the end of the valve or at the opposite end of the end including the valve.

4 and 5 show how to remove the removable cover 5. The removable cover 5 does not need to make a cut in the package, and can be easily pulled out by an operator by simply pulling the removable cover 5, and can be easily peeled off to some extent without damaging the package 1.

FIG. 6 shows the second end 4 fully open, while FIG. 7 shows the first end 3 with the second end 4 open and the removable cover 5 already pulled out. Shows vertical packaging supported by, the packaging is ready to be reused for supply filling, debris filling in construction work, and other purposes.

The packaging 1 which is the object of the present invention includes a main body 2 made of a tubular polymer fabric having a basis weight of more than 48 g. The basis weight of the main body 2 after laminating the tubular fabric varies between 50 g and 150 g, preferably between 40 g and 55 g, and preferably between 45 g and 50 g. Further, the weave density of the body 2 varies between 14/10 cm and 80/10 cm, preferably between 15/10 cm and 50/10 cm, preferably between 21/10 cm and 23/10 cm.

The filling valve 6, which may or may not be provided in the package 1, is a flat polymer having a basis weight of 20 g to 150 g, preferably 40 g to 55 g, preferably 45 g to 53 g. Made of fabric, the density of the weave varies between 14/10 cm and 80/10 cm, preferably between 15/10 cm and 50/10 cm, preferably between 17/10 cm and 20/10 cm.

Unlike the packaging found in the latest technology, the cover 5 for closing the ends 3 and 4 of the packaging 1 is removable, preferably with a basis weight of more than 20 g, preferably more than 49 g, from 50 g after lamination. It is made of a flat polymer fabric that varies between 200 g, 60 g-160 g, 100 g-120 g, preferably 107 g-112 g. Fragments further exhibit weaving densities greater than 14/10 cm, preferably greater than 21/10 cm, varying between 22/10 cm and 40/10 cm, preferably between 30/10 cm and 35/10 cm.

The weaving density of the fabric may vary depending on the clogging of the weaving of the twisted yarn. Thus, as an example, for a plying with a width of 5 mm, the weave density of the fabric is 20/10 cm for 100% clogging, i.e., 10 cm is fully filled and the clogging is 100%. Twenty 5 mm plyed yarns are arranged every 10 cm so as to be. In another example, for a 5 mm wide plyed yarn, the density can be 18/10 cm, which is a jam in the weave where there are voids between the plyed yarns and the weave is not completely filled. Means that is 90%. Clogs in the weave may be 100% or less, but not essential, but preferably, depending on the needs and adjustments of the process, the twisted yarns may overlap to be 200%, 300%, 400%, 500%, 1000%, Furthermore, it is important to note that the clogging exceeds 100% so that the clogging value reaches up to 1500%.

Accordingly, the removable cover 5 of the present invention is a polymeric fabric with a weave clogging between 60% and 1500%, which clogging is between 60% and 500%, between 60% and 350%, 80. It can vary from% to 200%, preferably over 100%. Thus, the removable cover 5 includes a fabric structure in which the plyings are overlapped so that the cover 5 is a denser, resulting in a stiffer and more robust material.

Further, the clogging ratio of the fabric weave for producing the main body 2 and the filling valve 6 is between 60% and 1500%.

As an example, tests were conducted to determine the pull-out strength of the removable cover so that the packaging could withstand three heights of drops. Although not required, preferably, the minimum strength required to pull out the removable cover was 2.5 kgf to ensure resistance to breakage of the packaging. The drop test was performed by dropping a large bag loaded with 50 kg from heights of 2 meters, 2.5 meters and 3 meters in the recumbent position. All of the large bags that showed a result of 2.5 kgf in the pull-out test of the removable cover withstood three drops from three specific heights, ie the packaging was not damaged by the impact of the drop. Other values can be achieved depending on the needs and adjustments of the process.

Accordingly, the present invention includes a removable cover 5 made of a polymer material, which guarantees the fixing resistance required for the safe transportation and handling of the loaded packaging, which withstands the drop without damaging the packaging material. In addition, a bag-shaped or large bag-shaped package 1 that allows the package to be opened for future reuse is presented.

Although an example of a preferred embodiment has been described, it is noted that the scope of the invention includes other possible variations that are limited solely by the content of the appended claims, which include potential equivalents. I want you to understand.
