Definitions

  • the present invention relates to a mailing bag, in particular a plastic mailing bag, for collecting and sending, in particular moist, waste, particularly preferably used coffee capsules or coffee-aluminum capsules.
  • the invention further relates to a method for collecting, in particular moist, waste, particularly preferably moist piece of waste.
  • the invention also relates to a method for recycling used coffee capsules, in particular used coffee aluminum capsules.
  • the invention is based on the use of the bags according to the invention for collecting and shipping, in particular moist, waste, particularly preferably used coffee capsules or coffee aluminum capsules.
  • Coffee capsules are disposable products. They are used regularly in so-called portion coffee machines. In order to brew the coffee present in the capsules, water or heated steam heated to a high pressure is passed through the coffee powder for a predetermined period of time with partial destruction of the capsule present in the coffee machine. The amount of coffee powder present in the coffee capsule is intended for brewing a single cup of coffee. It is therefore a portion packaging. Coffee capsules are becoming increasingly popular due to their easy handling. Another advantage of this type of coffee production is that it has a wide range of different types of coffee available, without having to add a large amount for each coffee taste note Having to stock coffee or beans. To ensure the freshness and integrity of the coffee powder used for this, the coffee capsules used are regularly made from an aluminum body and an aluminum cover. After removing the used coffee capsule from the coffee machine, it regularly has residual water as well as moist coffee grounds.
  • coffee-aluminum capsules apart from a regularly existing plastic inner coating, as described above, consist essentially of aluminum and are therefore virtually sorted, it would be desirable to make used aluminum coffee capsules accessible to a recycling process to the greatest possible extent. So far there is no adequate solution.
  • the present invention was therefore based on the object of being able to supply used coffee capsules, in particular coffee-aluminum capsules, to a recycling process in a simple and reliable manner and to the greatest possible extent.
  • a bag in particular a shipping bag, has been found with a substantially closed bottom end and an opposite opening, comprising a front wall with an inside and an outside and a back wall with an inside and an outside, which are in the region of their side edges and bottom edges are connected at least in sections directly or via side walls and / or side folds and / or a bottom fold, and wherein the opening edge the front wall is below the opening edge of the rear wall, so that the rear wall forms a protruding, foldable closure area, in particular a closure flap, and the closure area has a first adhesive, in particular adhesive strips, on the inside or on the outside, in particular on the inside, of the rear wall , and / or wherein the front wall on the outside in the overlap region with the closure region folded over along the opening edge of the front wall comprises a second adhesive, in particular second adhesive strip, and wherein the front wall on the outside beyond the overlap region with the closure region folded down, in particular a third adhesive third adhesive strip.
  • the bag according to the invention in particular the shipping bag, can be closed in such a way that water residues, moist coffee grounds residues and / or moist coffee grounds present therein cannot escape again through the original filling opening during storage and transport.
  • the bags according to the invention are manufactured in an expedient embodiment in such a way that neither water nor the wall materials of the front and rear walls, nor the side walls, if any, and also not the connection sections or seams of the wall sections connected to one another. Moisture can escape.
  • the leakage of moisture or residual water or of moist coffee grounds from the original filling opening can surprisingly be achieved with the bags according to the invention by providing a first and / or second adhesive in the closure area for closing the bag in the overlap area and additionally by beyond Provides a third adhesive on the front side of the overlap area, so that after the closed closure area has been turned over once and in particular several times, this folded-over closure area is glued again with the third adhesive.
  • the bags according to the invention can be used to collect and transport both used coffee capsules in a moisture-proof or moisture-proof manner in which the moist coffee grounds are still present, as well as those in which these moist coffee grounds have been removed by simply tipping them over, for example after tearing open the aluminum foil is so that there are only moist coffee grounds leftovers.
  • the bags according to the invention are also distinguished in particular by the fact that they can be made ready for dispatch in a simple manner.
  • the materials forming the bag according to the invention are particularly advantageously formed from a flexible material and accordingly deformable.
  • the further explanations are therefore preceded by the fact that the description relates to an unfilled, non-deformed state of the bag according to the invention, this bag, in particular the shipping bag, preferably being considered to be essentially flat.
  • the bag according to the invention is also expediently provided before being filled with moist waste, in particular used coffee capsules.
  • the use of the terms "front wall” and "rear wall” have been chosen as such to facilitate understanding.
  • the wall of the bag whose opening edge ends above the opening edge of the opposite wall can also be designed in the sense of a front wall in actual use and, for example, have the relevant product designation and / or logos, while the opposite wall contains no printing.
  • the mailing bag according to the invention is characterized in that the first or second adhesive, in particular adhesive strips, extends essentially from one side edge of the rear wall essentially to the opposite side edge of the rear wall, in particular continuously.
  • the third adhesive, in particular adhesive strip can extend essentially from one side edge of the front wall essentially to the opposite side edge of the front wall, in particular continuously.
