Definitions

  • the invention relates to a special use of a against the entry of gas, in particular of steam, tight container.
  • the invention also relates to the container for packaging itself.
  • Such resin-bonded abrasive discs designed as cutting or grinding discs have been known for a long time. They have a problem: their production, storage, sale and use can take a long time of up to several years. However, their service life deteriorates considerably over time, since the synthetic resin used as a binder absorbs moisture from the environment. As a result, the properties of the grinding tool change in the sense that it is inferior to increased wear during operation, so that the grinding tool has a shortened service life. The higher the amount of moisture absorbed by the synthetic resin, the higher the wear. Depending on this, the service life of a phenolic resin-bonded grinding wheel can be reduced by up to 70%. However, such a short service life of an originally packaged grinding wheel is perceived by the consumer as a serious quality defect. Previously known packaging could not solve the problem.
  • the object of the invention is now to provide a simple, inexpensive and convenient for the consumer way to better protect such resin-bonded grinding wheels against the absorption of moisture from the ambient air.
  • the basic idea of the invention is to pack a large number, for example a stack of 10 resin-bonded grinding wheels, in a sealed container against the entry of gas, in particular of steam, the container being designed so that it encloses the grinding wheels in a completely sealing manner.
  • "dense” in the sense of the invention means that a vapor barrier with a blocking value (S d value) of more than 1000, in particular of more than 1500, is present.
  • the container to a grinding envelopes completely enveloping shell, which is insofar "integral”, as their seams are cohesively connected or have.
  • the cohesive bond can be done by welding and the cohesive disposal by gluing or soldering.
  • a moisture absorption of the original packaged grinding wheels is prevented according to the invention by the use of a water vapor-tight container.
  • the moisture content in the synthetic resin of such wrapped grinding wheels corresponds approximately to the moisture content of a freshly produced grinding wheel even after prolonged storage.
  • the water vapor-tight reclosability of the once opened container is possible, but not necessarily part of the invention.
  • the grinding wheels are consumed relatively quickly, so that the problem of moisture absorption does not arise after the first opening.
  • the sheath comprises a layer of metal, which also implies that the sheath is made of metal.
  • the water vapor diffusion resistance of such a metal layer is so high that moisture diffusion through the layer is practically impossible. Even a very thin and thus flexible metal layer to be processed thus sufficient for the production of a water vapor-tight container.
  • the metal layer is applied as part of a composite film on a plastic film, in particular vapor-deposited.
  • a plastic film in particular vapor-deposited.
  • Similar packages are known in the food industry and are used, for example, for packaging ground coffee.
  • These composite films with the vapor-deposited metal layer are usually supplied by the meter and can be cut to any size required.
  • the film can be processed particularly easily to a packaging, wherein the seams are sealed in particular water vapor-tight by gluing or welding.
  • the sheath has a resealable closure, which seals against the passage of water vapor and in particular uses a pressure-sensitive adhesive for releasably connecting two closure parts.
  • a closure is known, for example, from the packaging of wet wipes.
  • the Tetra Pak ® As a packaging solution made of composite film, the Tetra Pak ® is known. Here is a composite system in which alutriniumbetiketes material is used, a water vapor-tight packaging produced.
  • the rigidity of the packaging is increased by a polygonal basic shape of the packaging with at least four corners, in particular with six or eight corners. In this way, the transport and the stackability of the packaging is additionally improved because the side surfaces juxtaposed packaging abut each other and give each other support
  • such a packaging has a stiffening element which at least partially surrounds the outer edge of the grinding wheel.
  • the stiffening element increases the stackability of the packaging, so that they are also easily stored in larger quantities can.
  • the stiffening element is formed of corrugated cardboard, which can be easily adapted to the respective packaging form.
  • the corrugated board is placed around the circumference of the stack of grinding wheels to be packaged and inserted into the package along with the grinding wheels.
  • the tin can offers, in which the sheath forms a stable one-piece container.
  • Such cans are gas-tight, yet easy to open.
  • a well-known example of this is the peanut can.
  • the metal container is water vapor-tight as long as the lid is firmly connected to the can.
  • Such a can may be provided with a simple closure having a tear-open, in particular tearable, sheet-metal tab along an embossment, the tab being accessible by means of an externally attached ring.
  • the sheet metal tab can, as in the case of the peanut can, be formed by the cover plate of a cylindrical can, which completely peels off when torn, the can is resealable in particular by an attachable plastic lid,
  • the advantage of such a package lies in the high mechanical stability and in the good stackability.
  • the can is made from a paper-containing composite film, the composite in particular comprising one or more metal foils.
  • a can has the shape of a cylindrical cup with a corresponding bottom.
  • the lid may consist of a polymer and / or metal foil, which can be pulled off with a tab made of a film.
  • Such a can is also stackable and can be resealed with a lid.
  • a strong hygroscopic compound for example a silica gel, is preferably introduced into the package prior to sealing.
  • the Figures 1 and 2 show a container or a package 1 for a plurality of resin-bonded grinding wheels 2, which are shown in the figures as an indicated stack.
  • the basic shape of the package 1 is based on a polygon with eight corners 3.
  • the eight side surfaces 5 of the package 1 emanating from the octagonal base 4 completely enclose the grinding wheels 2 contained in the package and end in a lid 6, opposite the base 4,
  • the bottom 4, the side walls 5 and the lid 6 are made of a composite material comprising at least one metal layer.
  • the seams are welded or glued.
  • the water-vapor-tight metal layer thus completely encloses the grinding wheels and prevents moisture from entering the interior of the packaging 1.
  • FIGS. 3 and 4 show a further preferred packaging 7 for grinding wheels 2 made of the composite with an overall dice-like shape.
  • the inner sides of their side surfaces 8 are additionally lined with a corrugated cardboard 9 acting as a reinforcing element.
  • a pre-cut tear line 11 along which the cover 10 can be separated from the rest of the packaging 7.
  • FIG. 5 shows a further embodiment in which the grinding wheels 2 are surrounded by corrugated cardboard 12.
  • the grinding wheels 2 are packed together with the corrugated cardboard 12 in a water vapor-tight film, not shown here.
  • FIGS. 6 and 7 show a package for grinding wheels 2 in the form of a box 13.
  • the lid 14 of the box 13 has a tab 15, over which it can be removed from the can.
