Definitions

  • the invention relates to an easy-to-open packaging with the features of the preamble of claim 1.
  • the parts of the packaging are mostly made of a plastic or metal foil or a metal / plastic composite film.
  • the connection is designed so that it can be released again under the action of an opening force. This requires a compromise between the hermetic sealing of the packaging and the firm connection along the sealing line, on the one hand, and a sufficiently low peeling resistance of the parts for easy opening.
  • the sealing line is understood here to mean the connecting surface area oriented along a line. In order to avoid the difficulties associated with such a compromise, it is also known to weaken the cover part by a line of weakness and thus to limit a tear-open part that can be torn open via the grip tab.
  • the measures according to claim 1 further develop packaging of the type in question for use in new areas of application, in that the packaging has a plurality of separate chambers hermetically sealed from one another. These chambers, which are separated by webs, can be used to take up the same contents in portions or to hold different contents in menu packaging or the like.
  • the packaging is expediently designed in accordance with the teaching of claim 2, so that the chambers can equally be exposed for access with a single opening process. It is essential here that the peeling resistance along the sealing line is only significantly reduced in the area of the top of the web compared to the peeling resistance of the sealing line running along the edge flange of the lower part.
  • the sealing force in the edge flange area can only be designed according to the strength of the connection and the sealing effect, since the opening process takes place along the edge flange along a weakening line lying within the sealing line.
  • the reduced peeling resistance in the area of the top of the web does not impair the security of the packaging, since this ensures through the tight seal connection along the edge flange is accomplished. In this way, a high adhesive force and hermetic seal is combined with a small opening resistance of the package in a simple manner. If the individual chambers of the packaging are to be independent of one another, the packaging is expediently designed in accordance with the teaching of claim 3.
  • the individual chambers can be opened independently of one another and at different times, while the chambers that have not yet been opened continue to seal and securely seal the contents of the packaging.
  • the cover part has a plurality of tear-open areas which are independent of one another and delimited by special weakening lines and which are assigned to each of the chambers.
  • the outline of the lower part or the individual chambers is not critical. A simple and safe opening of the individual chambers can be achieved in a simple manner with the aid of a grip tab according to the teaching of claim 4. According to this teaching, there is a great deal of freedom in the design options for the packaging and its chambers. You avoid grip tabs protruding over the edge of the packaging.
  • protruding tabs can also advantageously be provided for opening a chamber of the packaging independently, the tab being formed from the material of the cover part itself.
  • a procedure according to the teaching according to claim 8 has proven to be expedient.
  • the packaging consists of a bowl-shaped or cup-shaped lower part 1 of rectangular outline and an edge flange 4 and a cover part 2, which, as shown, can be flat or profiled.
  • Lower part 1 and cover part 2 can be made of the same or different materials. They preferably consist of foil materials, e.g. a metal, especially aluminum foil coated with a sealing compound or a metal / plastic composite foil.
  • the lower part 1 is divided into four separate chambers 9 to 12 by several webs 1a in the example shown.
  • the lid part 2 is connected along the edge flange 4 of the lower part 1 tightly and firmly with this by a sealing line 8.
  • Corresponding sealing lines 8a, 8b also extend over the tops of the webs of the lower part.
  • Each chamber is therefore closed and sealed by such a sealing line.
  • a weakening or notch line 5a to 5c or 13 is provided in the cover part for each chamber.
  • the score lines 5a to 5c are self-contained and delimit a tear-open area in the cover part 2.
  • the tear-open areas of the chambers 9 to 11 are each assigned a separately produced grip tab 7, which in the vicinity of the start section of the tear-open part by gluing, welding or cold or heat sealing 7b is firmly connected to the associated tear area.
  • Each chamber can thus be exposed separately and independently of the other chambers.
  • the chamber 12 is delimited by a special area 3 of the lower part 1.
  • a grip tab 14 is formed in the cover part 2 for the chamber region 12 from the film of the cover part on the edge of the packaging and is delimited by the line of weakness 13.
  • the grip tab area is also sealingly connected to the edge of the lower part, but the adhesive or connecting force is reduced in this narrowly limited area, so that the grip tab is closed by one tear the line of weakness 13 and peel from the edge flange of the lower part is exposed for the opening process. Details of the formation of such an area will be discussed in more detail below.
  • Figure 3 indicates a modified embodiment in plan view.
  • the cover part 16 of this embodiment is firmly and hermetically connected to the unspecified edge flange of the lower part via a self-contained sealing line 17.
  • a corresponding sealing line also runs along webs 20 through which the lower part is divided into a plurality of chambers 19a to 19b.
  • Each chamber is assigned a tear-open area in the cover part, which is delimited by a separate weakening line 18a to 18c lying within the sealing line.
  • the chamber 19a is assigned a handle tab 21a which is produced separately and is connected to the cover part by welding or gluing or sealing. From the figures it can be seen that the score lines are designed such that the chamber 19a can be uncovered with the aid of the grip tab 21a, independently of the chambers 19b and 19c.
  • tabs 21b, 21c for the chamber 19b and 19c are exposed above this chamber from the material of the cover part. It can be seen that these grip tabs each lie on the side of a separating web facing away from the associated chamber. In order to expose the associated chamber, the handle tab must be pulled over the associated web and separated from the web along the sealing line.
  • the relevant areas are designated 22b and 22c. The arrangement in these areas is such that the adhesive force between the lower part and the lid part is lower in these narrow areas of the sealing line than in all other areas, so that the grip tab can be peeled off the webs.
  • the reduced adhesive force in the narrowly defined areas 22b and 22c or in the area 14 according to FIG. can be achieved according to Figures 6 or 7.
  • a heat sealing tool 122 which communicates the pressure and the heat for heat sealing and which seals the cover part 120 e.g. connects to a web area 124 of the lower part 121 by heat sealing along the web area.
  • a heat-insulating insert 123 is provided in the heat sealing tool 122, which only allows the sealing heat to flow indirectly into the narrowly limited sealing area 22c. This leads to a reduced adhesive force.
  • cover part 125 and lower part 126 are connected along web 127 with a sealing tool 130, in which an insert 129 made of heat-conducting material and supported by spring 131 is provided.
  • the sealing heat is introduced directly into the narrowly limited sealing area 22c, but with a significantly reduced sealing pressure. This also leads to a reduction in the adhesive force.
  • the methods according to FIGS. 6 and 7 can also be used in combination.
  • the sealing time can also be reduced in the area.
  • FIGS. 13 to 16 A further possibility for developing a reduced adhesive force in narrowly limited areas, for example areas 22c and 22b of FIG. 3, is shown in FIGS. 13 to 16.
  • the web 115 of the lower part 110 is reduced in width in the narrowly defined length region 22c (FIG.
  • the grip tab in the crossover area has a width corresponding to the length of the web area 137 which is reduced in width compared to the web 136.
  • the web area has a projecting area 138, which preferably tapers.
  • the width of the grip tab in the crossing area is smaller than the length of the narrower web area.
  • FIGS. 17 and 18 show a further possibility of reducing the resistance to loosening in the region of the intersection between a sealing line and a grip tab.
  • the cover part 82 consists of a composite film consisting of several layers 82 to 85, which also includes the lower part 81 is firmly connected along the sealing line 76.
  • the tear area in the cover part is limited by the weakening line 77.
  • the grip tab is labeled 78.
  • a narrowly delimited area is outlined in the cover part by separate notch line 86.
  • the composite film is designed so that when pulling the handle tab 78 in the intersection, the layer 85 peels off from the cover part 79 or tears off and remains connected to the layer 91 of the lower part 81 via the connecting surface, so that the handle tab easily gets tight allows limited area to peel off from the lower part and is released so that the tear-open area 79 can be torn off along the score line 77 of the cover part.
  • each of the material of the lid part of the packaging 50 is delimited by a separate weakening or separating line 142 Handle tab 141 over a small chamber area of the lower part which is closed by a web, and preferably by a floor.
  • this lid area is reliably supported from below when the handle tab is broken open and exposed.
  • the handle tab at 116a crosses the connection with the bridge.
  • the design of this area corresponds to the embodiment described with reference to FIGS. 13 to 16.
  • the region 116a can also be formed when using a corresponding composite film according to FIG. 17 or FIG. 18.
  • the edge flange 51 of the lower part is connected to the cover part over the entire circumference along a sealing line 52 of high sealing strength. Within the sealing line, a tear area 54a to 54c is delimited by weakening line 53 above each chamber.
  • the embodiment corresponds to the exemplary embodiment according to FIG. 3.
  • the cover part 25 is basically connected to the lower part along the webs 28 via a sealing line 30, along which the connection has a reduced peeling resistance compared to the connection along the sealing line 26 along the edge flange.
  • the cover part is connected to a separately produced grip tab 29, which is applied at 29a over a separate area of the lower part by gluing, welding or sealing.
  • a weakening line 27 runs along the edge flange within the sealing line 26. When opening, the weakening line 27 is broken in with the aid of the grip tab 29 and the tear area is separated from the lower part by the webs 28, 30 with peeling loosening. As can be seen from FIG. 5, the weakening line 27 is expediently provided on the upper side of the cover part, for example in the aluminum layer 24a, and does not extend into the sealing layer 24b of the cover part 24.
  • each chamber of the lower part has a separate grip tab, which is however provided in the edge area of the packaging.
  • the edge flange of the lower part 31 has a widening 33 in the region of the grip tabs.
  • the widening has a limited slot 34, which is supplemented by notch lines on both sides towards the edge. Outside the interruption 34, the grip tab 35 can be firmly connected to the flange widening 33, while within the area 36 there is a narrowly delimited connecting surface with reduced adhesive force, so that the grip tab can be peeled off from the edge flange 33 in this area.
  • the lid part 32 is fixedly connected to the lower part 31 along sealing lines 37, within which a tear area delimited by a weakening line 38 is provided for each chamber.
  • the grip tab areas lie directly next to one another within the outline of the packaging and are separated from one another by lines of weakness.
  • the outer ends of the grip tabs are peelable to the underlying flange widening of the lower part of the container 40.
  • the peeling resistance along the sealing line 42 is weakened in the area of intersection between the sealing line 42, 44 and the grip tabs 45a to 45c, e.g. in the manner according to FIGS. 13 to 16.
  • Each tear-open area is delimited by a weakening line 43, the weakening lines immediately passing into the edge boundaries or the associated weakening lines of the individual tabs.
  • the grip tabs 48a to 48c which are connected via the line of weakness are exposed and are therefore not one Flange extension of the lower part supported. Otherwise, the arrangement in the packaging 41 with heat-sealing lines 46, 49 and weakening lines 47 is similar to that in the exemplary embodiment described above.
