Definitions

  • the invention relates to a device for opening and reclosing food-containing packages, in particular carton / plastic composite packages, with a pouring element with a peripheral flange for attachment to the package and a nozzle for pouring and arranged in the interior of the nozzle cutting element with a plurality the circumference of the arranged and directed to the package teeth and with a screw cap, wherein the cutting element intersects a pouring opening in the film composite material by a rotational movement of the screw cap for the first time to open the package.
  • Opening or pouring devices for food packaging have long been known in many embodiments. They are always based on cooperation with the pack to be opened, in addition to which the packings provided with such opening or pouring elements often have a prepared weakening in order to simplify the opening process. This may be a mechanical weakening line of the composite material or else a so-called overcoated hole in which a pouring opening is already stamped into the cardboard carrier material and then laminated on both sides with corresponding plastic layers and possibly further layers.
  • An opening and closing device according to the preamble of claim 1 is known from JP 2010 023 873 A known.
  • the object of the present invention is to further reduce the opening forces necessary for the first opening of food packages and to distribute them as evenly as possible over the entire opening process. Furthermore, a simple and as flat as possible construction and a lightweight construction of the pouring elements are to be achieved in order to further increase their profitability.
  • the teeth of the cutting element at its tip a high gradient, at their flanks a shallower gradient and at its tooth base again have a high gradient.
  • the invention has recognized that the particular shape of the tooth geometry with respect to its gradient, ie the slope of its tooth flanks, a faster, uniform puncture into the film material and also a faster and safer average at relatively low feed movement.
  • the force to be applied during piercing, cutting and cutting plays a special role.
  • the opening process can be divided into three phases here. These are in Fig. 5 , in which the applied force F is plotted over the distance s, graphically reproduced.
  • the solid line shows the "conventional" force curve of a cutting element formed as a cutting ring during the opening process, wherein the cutting ring is equipped with uniform (triangular) teeth.
  • the dashed curve shows the force curve during the opening process with a device according to the invention again.
  • Phase I the 'puncture force' is significantly reduced by the tooth shape according to the invention.
  • Phase II the cutting tendency decreases, the force is in this area slightly above that of an opening device with conventional tooth shapes (triangles).
  • the term 'cutting allowance' means the ratio of tangential to normal relative speed of the material to be processed and the working organ.
  • the three phases correspond to the different gradients of the teeth: with the almost needle-shaped tooth tips, punctured puncturing takes place with reduced force (phase I) for each tooth.
  • phase I reduced force
  • phase II gradient
  • phase III the high gradient again ensures a clean cut through the cut opening path.
  • the contour of each individual tooth (high gradient for grooving, reduced gradient for cutting, high gradient for cutting through) leads to a particularly clean cut, also due to a particularly elastic composite film.
  • the teeth of the cutting element are arranged directly adjacent to each other, so that touch their cutting.
  • This embodiment is particularly useful because it has a particularly fast separation of the slides result.
  • the sharpened tooth flanks can here extend to the tooth base, where the adjacent teeth already touch.
  • the number of teeth of a cutting element is between 10 and 20 and is preferably between 15 and 20.
  • tooth flanks are formed sharpened.
  • both tooth flanks of the tooth can be compared with a knife blade, which can be sharpened either one or both sides.
  • the contour of the tooth flanks has turns in the region of the shallower gradient. Also, these turns within the area with a flatter slope reduce the cutting forces due to the "sawtooth training" by temporarily increasing the Thomastexkeit.
  • the cutting element has a region without teeth.
  • the tooth flanks of each tooth are particularly preferably formed symmetrically. This applies to the geometry of the tooth flanks as well as the front and back of the tooth.
  • a further embodiment of the invention provides that the tooth flanks of each tooth can also be inclined in the cutting direction. In this way, the cutting process can be optimally adapted to the respective opening situation.
  • the membrane of hereulösendem foil composite can bring the teeth as little resistance as possible, provides a further embodiment of the invention that the teeth have a low thickness. In this way only a small cutting width is needed. In such a configuration, it may be advantageous for the teeth to be provided with longitudinal ribs for their reinforcement.
  • all teeth have the same height. This is particularly useful because the puncture process, the penetration of the plastic material takes place at the same time and the distances between the perforations are the same size.
  • a further embodiment of the invention provides that all teeth have the same geometry. This is of particular advantage not only in terms of a favorable design of the injection molding tool used, but also in terms of a low overall height of the device.
  • these guide means may be webs, cams and / or threads or threaded portions.
  • the opening movement is determined, which can be composed of a pure axial (piercing) movement, pure rotational (cutting) movements and their superposition.
  • a further embodiment of the invention provides that an active connection between the cutting element and screw cap is achieved by appropriate actuation elements.
  • Such a design is particularly useful because a single movement of the user, namely the screwing of the lid, sufficient to move the cutting element in the interior of the device translationally and / or rotationally to perform the opening operation.
  • FIG. 1 An inventive device is in Fig. 1 shown in the application state.
  • a pouring element 1 is provided with a peripheral flange 2 which is applied from its visible underside when applying the pouring element 1 over a 'coated hole' on a beverage package.
  • the pouring element has an upwardly extending tubular nozzle 3, which in Fig. 1 can not be seen, since it is covered by the inner cutting element 4, which is designed as a cutting ring, and is covered by a screw-top 5 on top.
  • a plurality of teeth 6, which are arranged over the circumference of the cutting ring, can be seen, which are all of identical design in the illustrated preferred embodiment.
  • Fig. 3 a further enlargement of two teeth 6 is shown, in which it can be seen that the respective tooth flanks 6A and 6B of each tooth 6 at the tooth tip first a very high gradient, ie a high slope, then a shallower gradient and in the area of the tooth base again high gradient. It can be seen that the adjoining flanks 6A and 6B extend as far as the tooth base through the teeth 6 arranged immediately adjacent, in order in this way to achieve an even better cutting action.
  • Fig. 2 also shows that the cutting element 4 has a region 7 without teeth. This design ensures that the film piece cut free from the pouring opening is not completely separated from the packing assembly, but remains connected to the packing assembly via a sufficient "bridge", so that it does not clog the pouring opening and thus hampers the casting process.
  • Fig. 2 shows further that a present in the interior of the cutting element drive element 8 protrudes radially inwardly to achieve together with provided in the interior of the screw cap 5 drive elements 9 and 10, an operative connection with the screw cap 5.
  • the flank 11 of the backdrop of the interior of the Screw cap 5 protruding drive element 9 ensures when turning the screw cap 5 for an opening movement of the cutting element 4.
  • the trained as a "fins" drive elements 9 and 10 are also the free space of the pouring opening by moving the film material in the toothless region 7 of the cutting element 4.
  • Fig. 4a to 4e shown schematically. It can be seen on a - only partially shown - package P, which is provided in the region of an over-coated opening with a membrane membrane M, sealed opening device, of which only the flange 2 and the nozzle 3 can be seen in the illustrated sequence.
  • Fig. 4d can be seen that the cutting element 4 has now penetrated so far into the package inside that the teeth have cut through the membrane almost completely.
  • the pouring opening is exposed and can the film residue 14 laterally pinch by further penetration of the cutting element 4 in order to achieve a reliable pouring through a free pouring opening.
