Definitions

  • the invention relates to a package with tear-open according to the preamble of claim 1.
  • the invention relates to a so-called child-resistant packaging of a multilayer film with at least one outer, mostly of polyethylene terephthalate (PET) plastic layer and at least one inner, thus facing the good aluminum layer.
  • PET polyethylene terephthalate
  • a layer of paper, oriented polypropylene (OPP) or oriented polyamide (OPA) can also be used.
  • such multilayer films consist of significantly more layers, as well as is still within the aluminum layer nor a polyethylene layer;
  • the usually also multi-layered printing is applied, up to a transparent protective layer for the printed image, but all this is not essential for the object of the present invention, the facilitated opening of such a package and therefore requires here no further explanation.
  • Packaging from such films is widely used for medicines, the aluminum foil being used against all external influences because of its excellent shielding effect (barrier layer or barrier layer) and the PET foil because of its high mechanical resistance. These are also used, if desired, to make the finished package "child proof" and there are various legal or standardized or agreed criteria as to when such a package should be considered child resistant. In any case, opening without tools is not easy by the above structure, and therefore various measures have been taken in the prior art to facilitate the opening here, if possible without giving up child safety.
  • the term "stick” should also be understood to mean a tubular bag in which a film is formed along a longitudinal seam into a tube and in predetermined sections of the tube is divided by transverse seams into individual volumes.
  • the longitudinal seam is arranged approximately in the middle of the length of the transverse seams, so that there is a scarf surface on the surface opposite the longitudinal seam and, due to the transverse seams, two resulting from bending of the tube material, usually strongly rounded side edges, in the region of the transverse seams rather sharp-edged, since they are welded together in the area of the transverse seams. Therefore, users are preferably attempting to open the package in the region of one of the transverse seams and starting from one of the side edges.
  • longitudinal seam and transverse seam adhesive or sealing strips are understood, through which the tubular film in the seam area is tightly connected to itself.
  • a rather bag-shaped or pillow-shaped packaging which has a longitudinal seam and transverse seams, but in which an opening aid is arranged at the location also obvious to children, which therefore can not be considered child safe, is from the US 3,608,815 known.
  • a special form with several weakening areas reveals the US 6,102,571 , wherein in particular in the region of the longitudinal seam, where the film is present in three layers and is particularly difficult to open, a further weakening region is provided to facilitate the opening.
  • Such a consideration of the problems in the area of the longitudinal seam in a stick also reveals the EP 1 152 947 , The contents of the cited documents are made for the jurisdictions in which this is possible, in particular for the USA, by reference to the content of the present application.
  • the invention thus essentially provides, at a distance from the edge of the stick or the pad (cushion) in at least one of the packaging surfaces, two intersecting lines of weakness, each preferably straight, provided, wherein the angle between the lines of weakness at the intersection between 60 ° and 90 °.
  • one of the weakening lines runs parallel to the adjacent edge (edge) of the packaging, and the other substantially normal thereto; in this case, their point of intersection is preferably at some distance from the nearest corner of the package.
  • the weakening line which runs parallel to the adjacent edge, the fold line and the normal line of weakening are the tear line.
  • the intersection is near one of the corners of the package, but outside the region of the seal seam (s), and the two lines of weakness are twisted by about 45 ° with respect to the edges of the package.
  • the line of weakness which cuts off the corner, the fold line and the line of weakness running in the corner is preferably the tear line. If only a small opening to be created, the lines are reversed in their functionality; This can be easily identified by appropriate labeling.
  • the Fig. 1 represents a cushion-shaped packaging, which is composed of two, preferably identical films 7, 7 '.
  • a substantially rectangular package 1 is limited by four sealing seams 2, 3.
  • the sealing seams 2 run parallel to one another and the two sealing seams 3 are also parallel to one another, but normal to the sealing seams 2.
  • Fig. 1 represents a purely schematic section along the line AA, so was omitted on the representation of the goods and lying in the direction of the cut seal 3 for the sake of illustrating the essential details. From the secondary character go out the two sealed seams 2, the two films 7, 7 ', which make up the packaging 1, are easily recognizable. It should be noted that a section normal to that of the line AA would have the same appearance.
  • the opening aid according to the invention in the form of two weakening lines 4, 5 is now provided in the region of one of the sealing seams 2, 3.
  • the weakening line 4 runs parallel to the adjacent edge 2 and the weakening line 5 essentially normal (generally perpendicular).
  • These two lines of weakness are not just in the in Fig. 1 visible top sheet 7 is provided, but also aligned in the view of the Fig. 1 in the underlying film 7 '.
  • the user uses now the line of weakness 4 as a bending line, whereby the line of weakness 5 along which the package 1 is torn, in the edge region, which is now formed by the bending line 4, and the package can now be easily torn along the line of weakness 5, although they are in This area now has twice the strength.
  • the arrangement and length of the lines of weakness 4, 5 depends on the size of the package 1, the item contained and after the answer to the question of whether the package should be separated at least substantially in two parts, or whether the creation of a removal opening is sufficient.
  • the Fig. 2 shows a variant in which the lines of weakness 4, 5 are moved into one of the corners of the package 1, and extend substantially in the bisector of the sealing seams 2, 3 or normal to the first line of weakness. It is possible to bend or buckle the package around the line of weakness 4 and then along the weakening line 5, thus tear open substantially diagonal to the packaging. It can be seen that it is thus possible to create a very large opening in the gap-open state without the risk of accidentally spilling or losing an integral good, for example a contact lens.
  • the Fig. 2 also shows a variant of the package 1 per se, namely a package which consists only of a film 7, which is folded along an edge 6 and closed along the three remaining edges with sealing lines 2, 3. Again, this is clearly visible in the minor figure, which again shows a schematic section along the line AA.
  • an opening aid analogous to the Fig. 1 provided this may, if an easy opening is desired to be provided in the region of the cover edge 6, since it is then not necessary to bend through one of the sealing seams when bending around the line 6 parallel to the weakening line and the subsequent opening.
  • the Fig. 3 shows a variant of the invention in a so-called stick, again in plan view and in schematic section. It can be seen that here there are two cover edges 6, since the corresponding sealing seams or the sealed seam 2 is displaced into the middle of one of the surfaces and forms the longitudinal seam 2 'there.
  • the weakening line 4 was shown again for bending parallel to the longitudinal seam and the weakening line 5 for tearing normal to her.
  • the lines of weakness 4, 5 are to be provided in the PET layer, since it is this layer that provides the mechanical tear strength of the envelope of the package 1. At the same time, this gives a first visual aid for finding the opening location.
  • This orientation aid is preferably reinforced by appropriate design of the printing of the packaging 1.
  • the weakening lines 4, 5 can be produced in all known ways, thus mechanically or else, which is preferred, by means of a High-power jet, preferably by means of laser.
  • the coordination of the wavelength and power of the laser on the material used is not a problem for the expert in the knowledge of the invention and the field of application, as well as the leadership of the laser against the film, it can therefore be waived, here in detail.
  • the weakening lines 4, 5 itself should still be stated that they do not have to be straight, but may also be wavy or curved; they can be designed very differently to the purely schematically represented lines. These may be lines where the PET layer is either only weakened or at least substantially removed; the lines may be continuous or they may be dotted or dashed lines, the production and the effect on the opening characteristics are known and described in many ways, and they may be brought to the desired values by a few simple tests, to the knowledge of the invention.
  • the packaging must by no means be rectangular or even square, polygonal outlines and also those with at least partially curved outline can be used.
  • the terms "parallel to” or “normal to” are then to refer to tangents or secants of this section.
