Definitions

  • the invention relates to packaging, for. B. for surgical instruments, made of a plastic sheet and a paper web, both of which are sealed to one another at the edge which encloses a receiving space formed in the plastic film sheet, with an attachment point for an opening process in which the sheets are peelable from one another along the edge, wherein the edge has at least one group of narrow, elongated sealing elements which are uniformly distributed.
  • the goods are introduced into a pre-formed, deep-drawn depression of a plastic film which is adapted to the goods, and sealed with a paper web.
  • the sealing is done in such a way that the "peel" ability is maintained when opening and sufficient sealing against penetrating germs, dirt and the like. Like. Is achieved.
  • the narrow, elongated sealing elements bring about the mechanical cohesion of the paper web with the plastic film.
  • the packaged goods are subjected to the sterilization process, in which the germs are killed by appropriate gassing with a suitable gas.
  • the packaging is opened, the paper web and plastic film are peeled apart from each other, which is facilitated by the shape of the sealing elements.
  • the pull-off direction usually corresponds to the main fiber direction of the paper.
  • the invention has set itself the task of creating a packaging, for example for surgical instruments, which enables an absolutely tight seal even with complicatedly shaped objects and depressions.
  • the invention is based on a packaging of the type mentioned above and proposes that the elongated Siegelun g elements have a limited length and connect the individual sealing elements at intervals.
  • This embodiment has the particular advantage that the plastic film, which may be slightly warped due to the deep-drawing, can dodge in the spaces between the individual longitudinal sealing elements and does not cause any folds. Tensions that occur in the film during sealing can even out.
  • the individual sealing elements can be arranged directly in lines one behind the other. However, a slightly offset arrangement is also possible.
  • the elongate sealing elements are arranged parallel to one another.
  • the elongate sealing elements also achieve good tightness, and the opening process is particularly simple since the pack can be opened without jerking.
  • the elongate sealing elements are angled in their course. The sealing elements themselves can be angled or they are arranged at an angle to one another. In this arrangement, the tightness is particularly high, especially when the sealing elements, as in the other embodiments, lie close together.
  • the elongate sealing elements have different lengths and / or widths.
  • this embodiment enables the deep-drawn plastic film to yield well, so that the disadvantages of warping are avoided.
  • the tightness is also excellent, especially when the individual sealing elements are very close together.
  • the packaging consists essentially of the paper web 5 and the plastic film 6, both of which are sealed together at the edge 4. As is known per se, the plastic film 6 forms a depression and receives the goods 7 therein.
  • the edge 4 of the packaging has the elongated sealing elements 1.
  • the elongated sealing elements 1 have a limited length and are interrupted by the distances 2.
  • punctiform sealing elements 3 are arranged between the elongate sealing elements 1 and increase the tightness of the packaging.
  • the plastic film 6 tends to crease at the edge during the sealing process. Due to the distances 2 between the elongate sealing elements 1, the curvatures in the plastic film 6 are compensated and the formation of folds at the edge 4 is avoided.
  • FIG. 2 shows a parallel offset arrangement of the elongate sealing elements 1.
  • the elongate sealing elements alone achieve a satisfactory tightness of the packaging.
  • Such an embodiment, as shown in Fig. 2, is particularly easy to manufacture.
  • the elongated sealing elements 1 are also offset from one another and are at an angle to one another.
  • the angle can be chosen arbitrarily.
  • the punctiform sealing elements 3 increase the tightness of the packaging.
  • angularly shaped elongate sealing elements 8 are shown. These angled sealing elements 8 are offset from one another and their sealing effect is supported by the punctiform sealing elements 3.
  • FIG. 5 shows an arrangement of elongate sealing elements of different lengths and widths.
  • the larger elongated sealing elements 1 alternate with smaller sealing elements 9.
  • a tear tab 10 facilitates the opening process.
  • FIG. 6 shows a greatly enlarged and drawing-exaggerated section through part of a package with a paper web 5 and a plastic film 6.
  • the course of the fibers 11 results from the production. Since the contact surface 12 of the sealing elements 1 on the individual fibers 11 is small compared to their length, there is no risk of pulling the fibers 11 out of the fiber structure in the paper web 5. It does not matter in which direction to the paper web with respect to its main fiber direction the pull tab 10 is located. It is advantageous if the longitudinal direction of the sealing elements 1 forms an acute angle with the main longitudinal direction of the fibers 11 in the plan view.
