Definitions

  • the present invention relates to packaging with a basic packaging body, wherein the basic packaging body delimits an interior space for storing bulk goods.
  • the invention also relates to a method for producing such a packaging.
  • Packaging for storing bulk goods such as cement, sand, lime, granules or the like are often bags or valve bags z. B. be filled with 25 kg or 50 kg of the bulk material in question.
  • the basic packaging body is locally destroyed by the hooks, so that some of the bulk material escapes. Furthermore, the basic packaging body can tear open over a large area when handling with the hooks, so that a large part of the bulk material escapes and possibly becomes unusable. The escaping bulk material can also lead to health problems for the worker and damage to the environment can occur.
  • the invention is based on the technical problem of specifying packaging which, when filled, enables improved manual handling. A method for producing such a packaging is also to be specified.
  • the invention relates to packaging with a basic packaging body, wherein the basic packaging body delimits an interior space for storing bulk goods.
  • the packaging has at least one tab, the tab extending overhanging from an outside of the packaging base body facing away from the interior and the tab having a through-opening for inserting a hook.
  • the tab improves manual handling of the package in a bulk filled condition.
  • the tab can be used to pull or grip the packaging by hand without tools.
  • a tool such as a hook or the like can be inserted into the through hole of the tab to move the package using the tool.
  • the passage opening of the tab is therefore a defined point of attack for attaching a tool, such as a hook or the like. Improper transport of packaging filled with bulk goods, for example by driving a hook into the basic body of the packaging, can therefore be avoided. This prevents the basic packaging body from being destroyed and bulk material escaping from the interior.
  • a strap is therefore not a loop or carrying loop, the are usually attached with two ends to a respective object to be transported.
  • the tab is a limp, flexible band.
  • the tab can extend freely overhanging and protrude laterally beyond an envelope of the interior of the basic packaging body when filled with bulk material.
  • the tab can have two or more layers.
  • the tab can be formed from a strip-shaped band material that is folded twice or multiple times or is layered in two or more layers in the manner of a sandwich material.
  • the structure of the tab is reinforced in that at least one stiffening element is assigned to the through-opening of the tab, the stiffening element enclosing the through-opening at least in sections.
  • the stiffening element can be an eyelet or a ring made of a plastic, a rubber or a metal material.
  • the stiffening element can be a welded collar or a local thickening of the wall thickness of the tab.
  • the through opening can have an opening width that is 0.5 cm or more.
  • the through-opening can have an opening width that is 10 cm or less, in particular 5 cm or less. The size of the through-opening can thus promote simple and reliable insertion of a tool for handling a packaging filled with bulk material.
  • the through-opening has a polygonal shape, for example, ie, for example, has a triangular, square or rectangular shape, or that the through-opening has a has an oval shape.
  • the through-opening of the tab is circular, with a diameter of the circular through-opening being greater than or equal to 0.5 cm and smaller than or equal to 10 cm, in particular smaller than or equal to 5 cm.
  • the circular through-opening can be produced in a simple and cost-effective manner, and a notch effect under load is reduced in comparison to the polygonal shape.
  • the packaging has at least one additional strap, the additional strap projecting from the outside of the basic packaging body facing away from the interior and the additional strap having a through-opening for inserting a hook.
  • the additional tab can be configured identically to the tab described above.
  • the tab and the additional tab can be arranged on opposite sides of the packaging body.
  • the handling of the packaging in the filled state can be improved by two mutually spaced attack or attachment points in the form of the tab and the additional tab.
  • the packaging can have exactly two tabs or exactly four tabs.
  • Each of the tabs can have at least one through opening.
  • each of the tabs can have exactly one through opening.
  • At least one cover sheet can be attached to the basic packaging body, with at least one flap being part of the cover sheet.
  • the flap of the cover sheet can be the flap described above or the further flap described above.
  • Such a cover sheet serves on the one hand to stiffen the packaging and on the other hand to realize a tab in a simple and cost-effective manner.
  • the cover sheet is folded at least once in the area of the flap. In this way, a two-layer or multi-layer tab can be provided in a simple and cost-effective manner, which is formed from two or more layers of a material of the cover sheet.
  • the folded layers of the cover sheet can be connected to one another in a material-to-material or adhesive manner, in particular welded or glued.
  • a fastening section of the cover sheet with which the cover sheet is connected to the basic packaging body, has a smaller wall thickness than the flap.
  • the cover sheet therefore has greater flexibility in its fastening section fastened to the basic packaging body, while the cover sheet is locally reinforced in the region of its flap.
  • the cover sheet has a higher strength than the basic packaging body and/or the cover sheet has a higher strength than a reinforced or sealed bottom of the basic packaging body. If it is said here that the cover sheet has a higher strength than the packaging body and/or a reinforced or sealed bottom, this means that the cover sheet in a strip test when a yield or yield point is reached can withstand a higher stress than the packaging body or a reinforced or sealed bottom of the package body.
  • the cover sheet can be formed from the same material from which the basic packaging body is made.
  • the cover sheet can be formed from a material that is different from the packaging base body.
  • the material of the cover sheet can have a higher yield point and/or a higher tensile strength than a material of the packaging base body.
  • the cover sheet can be welded or glued to the packaging body.

  • the cover sheet can have an adhesion promoter layer facing the basic packaging body in order to promote weldability.
  • the cover sheet can extend over the entire length of a side surface of the basic packaging body and protrude beyond the side surface in a longitudinal direction.
  • the area of the cover sheet that protrudes beyond the side surface is the flap of the cover sheet. It can be provided that the cover sheet completely covers the side surface. Accordingly, the packaging is formed in at least two layers in the area of the side surface by the packaging base body and the cover sheet, with the cover sheet also forming the flap.
  • the cover sheet extends over the entire height of a side surface of the basic packaging body and protrudes beyond the side surface in a vertical direction.
  • the area of the cover sheet that protrudes beyond the side surface is the flap of the cover sheet.
  • the cover sheet completely covers the side surface and the tab is also formed on the cover sheet.
  • a length of the side surface can be less than a length of the cover sheet.
  • a height of the side face can be less than a height of the cover sheet.
  • At least two cover sheets are arranged on at least one side of the packaging body, which cover sheets overlap at least in sections, with each of the cover sheets having at least one flap. Accordingly, in particular two cover sheets can be provided, with each of the cover sheets having at least one flap in order to provide two points of attachment for handling the packaging adjacent to the relevant side surface. Provision can be made for each cover sheet to have exactly one flap. According to a further embodiment of the packaging, it can be provided that at least two cover sheets are also arranged on a further side of the packaging body, which cover sheets overlap at least in sections and each have at least one flap. Provision can be made for each cover sheet to have exactly one flap. For example, a package with four cover sheets and four flaps and a total of four through openings can be specified in order to improve the manual handling of the package when it is filled with bulk material.
  • At least one cover sheet can be arranged on opposite sides of the basic packaging body, with each cover sheet having at least one tab. Provision can be made for each cover sheet to have exactly one flap. In this way, the manual handling of the packaging in the filled state can be improved.
  • the tab is an integral part of the basic packaging body or two or more tabs are an integral part of the basic packaging body. In this case, there is no need to additionally attach a cover sheet with a flap, or at least one cover sheet without a flap can be provided to stiffen the packaging.
  • the basic packaging body can have a plastic fabric or consist of a plastic fabric.
  • the packaging body can be a plastic fabric sack with a cross bottom and/or a sealed bottom.
