Definitions

  • the invention relates to a resealable all-round packaging made of two molded parts made of dimensionally stable plastic with an essentially rectangular longitudinal and transverse extension and interlocking connecting elements provided on the longitudinal and transverse edges, and a tool for producing such packaging.
  • DIN 55 512 specifies the dimensions of such all-round transparent packaging in the manner of a complete set, so that a package size adapted to the dimensions of the objects to be packed can be selected in each case.
  • a bowl with an integrated lid for liquids containing food which is made of thermoplastic film by deformation under pressure and heat.
  • This bowl has a circumferential, laterally projecting edge strip on both the bowl rim and the lid.
  • the rim of the bowl has a spring bar with a rectangular cross-section projecting upwards and in a closed hexagonal shape following the course of the bowl walls integrally formed, which engages in complementary grooves in the edge strip of the cover.
  • the groove width is chosen to be somewhat smaller than the web width of the spring bar on the bowl with a hexagonal cross section.
  • the bowl and the lid are connected to one another along one of the side walls in the region of the two edge strips via a web which is U-shaped in cross section and which forms a folding region.
  • the reclosable all-round packaging consists exclusively of two molded parts which are connected to one another via a film hinge or a folding area formed between them. One molded part can be pivoted relative to the other around this fold area.
  • the connection elements provided regardless of whether they are tongue and groove connections or other connection types, are provided in the edge areas and can be clamped or snap together. If necessary, interruptions are provided in the connecting elements, for example to ensure ventilation of the cavity.
  • a double deep-drawing tool is required, which can be used to form both molded parts from e.g. Permitted by infrared light heated film made of thermoplastic material, the two parts being connected to each other via the film hinge.
  • the costs of the machines and the deep-drawing molds increase with increasing packaging size, e.g. of the standard packaging sizes specified in the pre-cited DIN standard. Up to a length or width of approx. 250 mm, the molded parts can be produced together in a deep-drawing machine with a deep-drawing tool used in a cost-optimized manner.
  • larger packaging for example with a length or width of more than approx.
  • the invention has for its object to provide a design of the all-round packaging, which reduces the machine costs and allows packaging of various sizes can be made with such a machine, regardless of whether these sizes are standardized or different sizes of which can be chosen.
  • the design should be able to be manufactured in rationally producible tools.
  • the object is achieved by the design specified in claim 1 and by using a tool system having the features specified in claim 15, which in the form of a modular system enables the production of any desired size of packaging within a very wide range in a simple manner by means of the modular system Parts allowed for one tool. It goes without saying that the specified tool system can be used in the same way for both molded parts of the all-round packaging, regardless of whether they are produced in one piece or in two parts in the case of larger packagings.
  • the invention is not limited to a deep drawing process. Rather, the molded parts can also be produced from plastic by injection molding or blowing technology or by pressing technology. Advantageous designs of the tool system are specified in claims 16 to 18.
  • the parts are formed in one piece and are connected to one another via the folding area.
  • the same type of machine it is also possible to produce packaging of the same structure in the upper range of the packaging sizes, in that instead of the one-piece design, two parts are produced separately in tools, which have a joining area for the mutually pivotable connection, which essentially corresponds to the folding area and differs from the folding area, for example, only in that the two parts are separated from one another at the folding edge.
  • the same connecting elements can be used in the joining area for the latching connection as are also provided for the folding or bending around a film hinge in the folding area. It goes without saying that when using male and female connecting elements, these must be provided correspondingly in the edge areas in order to establish a firm connection between the two molded parts.
  • a folding area in the form of a film hinge is provided between the connecting elements on the joining area and the actual hollow shell, which is to receive the goods to be packaged, so that after joining in the joining area, one molded part compared to the other Molded part is pivotable, whereby the package can be opened and closed, in the same way as if both parts have one Folding area or a film hinge are connected to each other.
  • This embodiment can of course also be used for packaging, the two molded parts of which are formed in one piece. In the area of the additional film hinge, however, no tongue and groove connection can be provided running perpendicular to the folded edge, since otherwise one molded part would not be able to bend or pivot relative to the other.
  • tongue and groove connections as connecting elements between the two individual parts, but also between the two folded molded parts
  • other types of connection such as push-button connections formed from the webs of the folding area, can also be used. Welding is also possible, in particular if a second parallel folding edge or only this is provided.
  • the design can also be enlarged in a further embodiment of the invention in a modular system.
  • joining parts are inserted into a transverse or longitudinally divided packaging. These can be connected to one another by means of locking or sealingly locking connecting elements.
  • these joining parts should, however, be formed in one piece in the deep-drawing process as part of the all-round packaging.
  • a tool system is specified that enables the assembly of different shape sizes in a modular system from edge parts and intermediate parts in a simple manner.
  • This modular system can also be used if an advertising medium in the form of an advertising space is provided as an extension of the hollow shape that receives the packaged goods.
  • the advertising area can be adapted to the size desired using segments and joining parts which are also provided in the modular system and which are assembled in the form and connected to one another by means of clamping devices.
  • a fastening section or strip can be provided, which is provided on both parts or only on one molded part and is of the same size as the packaging and has the same width in relation to the packaging or the same dimensions in both directions. Since this tool part is always the same, it is provided that, in order to widen the packaging, the joining parts laterally join the fastening section, preference being given to the symmetrical lateral configuration, provided that no second fastening strips are provided distributed over the width.
  • an all-round packaging 1 made of dimensionally stable plastic with two folding parts 2, 3 can be seen in the open state. These are movable in a bending area 4, so that one can be folded onto the other and thus the closed transparent packaging is formed.
  • the edge parts 5, 6 of the folding parts 2, 3 are flatly fitted into one another in the closed state.
  • the folding parts 2, 3 are manufactured individually according to a partial aspect of the invention.
  • the molded part 2 has an advertising field 11, the a fastening strip 12 adjoins a suspension recess 13.
  • the second molded part 3 also has a contour-adapted design, so that when folded, an advertising space for inscriptions etc. is available on both sides and the packaging with content can be hung up, for example, in a shelf compartment.
  • the two fastening strips 12 on part 2 and on part 3 are shaped in such a way that by interlocking the side wings of the strip 12, these can be inserted into the inclined recesses 14 visible below.
  • Fig. 1b it is shown that the edge parts 5, 6 can be provided with locking knobs 10 in a development of the invention.
  • the two parts 10a, 10b are complementary to each other. As can also be seen in FIG. 1b, they preferably have a dovetail shape.
  • the shape and design of the other parts of the transparent packaging can correspond to the shapes explained in the aforementioned DE-A 36 38 373 and is left to the person skilled in the art.
  • FIG. 2 compared to FIG. 1, it is shown enlarged that and how the folding parts 2, 3 engage in the bending area 4 by means of a latching flat fit 7.
  • the recess 7a and the elevation 7b are pressed or pushed into one another. Thereafter, at least one welding point 9 can optionally be attached.
  • the packaging shown in FIG. 1 can be enlarged and reduced in a simple manner if the tool is designed according to the further aspect of the invention and is assembled from individual elements or segments, these having plane-parallel joining sides.
  • the edge areas have the same mirror image structure and are uniform in cross-section over larger sections.
  • the parts to be joined or segments have the same cross-sectional shape and can be used for extension or for shortening.
  • the folding area 4 which is designed using the machine size as a separating area, that is to say that when both molded parts can no longer be molded in one machine in the machine, the two molded parts are produced separately in the same machine using their own tools become.
  • the folding area is then designed as a joining area and has connecting elements on both parts which, when pressed together, bring the two shell-shaped molded parts into a closed package.
  • the change from a certain packaging size from a folding package to a two-part packaging also has advantages for the packaging process, since the packaging table can be used both for the folding packaging and for larger one-piece packing trays, which are then closed by means of the second counter-tray.
  • the packaging can be enlarged or reduced in both the longitudinal and transverse dimensions in a simple manner if the molding tool has segmented edge moldings which can be removed or inserted.
  • these edge parts must be provided in the transverse direction, that is to say the foldable area must be extended, or in the case of the larger packaging the individual shell must be extended by the edge segments to be joined together.
  • the inner hollow shell can be adapted to the new size by joining parts, as well as by joining parts with a specially incorporated shape, in order to be able to adapt the cavity to the packaged goods, for example.
  • the modular system has proven itself and contributes to the substantial cost reduction of tool sets, since the same segments of the tool box system can always be used to create different tool sizes. This is true even if the advertising window 11 is to be enlarged. In this case e.g. contain an extension segment which connects laterally to the fastening strip 12, e.g. is used on the dashed line 15. This must also be provided as a mirror image on the other side, so that the packaging can be suspended symmetrically.
