Definitions

  • the invention relates to a packaging for liquid and / or solid contents, consisting of a cup-shaped lower part with a circumferential upper flange and a cover with a circumferential flange, at least the facing surfaces of the flanges having plastic and a circumferential, in between the two flanges a closed weld seam is attached and a tear line in the form of a line of weakness is provided for the formation of a connecting strip with a gripping tab towards the center of the cover.
  • a weld seam is provided on the outside between the two flanges of the cover and the lower part, but this weld seam is not self-contained but runs in a spiral, so that the connecting strip is located, inter alia, where two weld seams run parallel to one another .
  • a gripping tab is also formed on the connecting strip, but this extends from the outside through the interrupted outer weld seam.
  • the weld seam continues in the tear direction in a tear line that runs parallel to the weld seam, but is also not self-contained.
  • the layers of the plastic material of the cover and of the plastic material of the cup-shaped part lie flat on one another without being sealed to one another. Under special conditions, a leak can occur here, but in particular the production of the weld seams and lines of weakness, which are carried out according to a specific pattern, is complex.
  • the invention is therefore based on the object of improving packaging of the type specified in the introduction in such a way that the manufacture is simplified and the tightness and the ease of use are improved.
  • the weld seam runs through the gripping flap, which consists of two layers, the lower one is integrally formed with the cup flange and the upper is integrally formed with the cover flange that the part of the tear line running in the region of the gripping flap in two Sections divided, of which the lower section in the layer on the cup flange extends along the boundary between the cup flange and the gripping flap, and the upper section in the layer on the cover flange extends a little way into the gripping flap, and that the remaining part of the tear line as both flanges weakening line is formed.
  • the shape of the packaging according to the invention requires a flange on the cup-shaped lower part and a flange on the lid, which move the packaging at the same location.
  • Packaging of this type can be used, for example, for foods that contain solid and / or liquid components.
  • the connecting strip can be torn off and the cover can thus be removed from the pack.
  • the packaging material can consist entirely of plastic or be a composite material, the surfaces of which are provided with plastic.
  • the weld seam runs through the gripping shaft itself not only in the flange area but at the point where the gripping shaft is attached.
  • the gripping tab In the area of the gripping tab there is not a second weld in the normal extension of the flange edges.
  • a part of the gripping tab, which according to the invention consists of two layers, is thus directly connected to the inside of the packaging.
  • the tear line divides in the area of the gripping tab.
  • the packaging in the area of the gripping flap is therefore configured differently than conventional embodiments.
  • the weld seam connects the cup flange to the cover flange and runs close to the outer edge; while the tear line runs parallel at a small distance of 0.5 to 5 mm, preferably 1 to 2 mm, from the outer weld seam to the center, and the line mentioned weakens the two flanges.
  • the above-mentioned lower section of the tear line is in a different way than the upper section of the The tear line runs with the result that the gripping tab still has the two layers at its outermost front end, but in the rear area under the projection only consists of the lower layer, which is torn off from the cup bottle.
  • the above-mentioned projection on the cover flange thus results from the partial separation from the gripping tab, namely its upper layer.
  • the first separation point at which the two sections of the part of the tear line running in the region of the gripping axis separate from one another, is connected to a tear-weakening line crossing the weld seam.
  • This line of weakness begins at the outermost edge of the two flanges and extends at an angle to the weld seam in such a way that it then leads to said first separation point.
  • This separation point lies - seen in a top view of the packaging - within the weld seam running on the outside.
  • the tear weakening line can be a perforation line that is designed so that it crosses the weld seam but does not make it leaky. It is known in the art to properly design such a point where a line of weakness crosses a weld seam in a liquid-tight or even gas-tight manner. Then the end user still needs a certain amount of, albeit very little, force to open such a package in order to tear off the gripping pocket at the beginning in the area of the weld seam.
  • the invention has taken these aspects into account in particular by the further advantageous measure that the outer end point of the tear-weakening line lies in the tip of a wedge-shaped line, along which the gripping pocket approaches at the tearing end and the outer edge of the lid and cup flange. Seizes the user who wants to open the package, the gripping tab in this embodiment just described, it inevitably leads the movement, and thus the Einr conductedkraft to a point, namely, d? N k ercie en outer end point of the Einr employedschwownungsline. Focus at this point; i the tensile forces, so that the force for tearing off the connecting strip is considerably reduced.
  • the weld seam runs across the gripping tab to close to its edge and then following the edge to the tear-off end and if the upper section of the part of the tear line running in the area of the gripping tab runs closely next to and parallel to the weld seam .
  • the weld seam connects the two layers of the Gripping tab just as it connects the two layers in the area of the flanges. Thanks to this all-round connection, the packaging is perfectly sealed before the first opening.
  • the simple design of a single weld seam also simplifies the manufacture of such packaging.
  • the weld seam crosses the surface of the gripping tab, because the weld seam coming from the flange edge is guided radially outwards from the center of the packaging to the edge of the gripping tab, and the weld seam then extends to the tear-off end of the gripping tab, then you can on the one hand get the projection dimensioned and designed on the cover flange with reasonable ease of use and on the other hand divide the gripping tab itself into two suitable parts, namely the outer handle part that the user must grasp to start tearing, and the rear area of the gripping tab located under the projection on the cover flange that delaminates itself from the upper layer, so to speak.
  • the weld layer holding the two layers of the gripping pocket together is severed by the upper portion of the tear line, and then the upper layer can be easily separated from the lower one, with the result that the upper layer remains in the form of the projection on the cover flange, while the gripping flap with the lower one Layer and a narrow remaining strip of the top layer can be torn off with the weld.
  • the tear-off end is where the weld seam is guided radially inwards from the edge of the gripping tab to the outer edge of the flanges.
  • the entire gripping tab is designed such that it is triangular, trapezoidal or arch-shaped in plan view such that the weld seam and its edge at the widest end of the gripping tab is the furthest away from the flange edge and gradually radially inward from this point again Edge of the flanges is returned.
  • the outer edge strip of the gripping tab contains the weld seam, along which the upper layer is firmly connected to the lower one.
  • This strip on the edge of the gripping flap also consists of two layers after tearing off, but is only narrow in plan view like a ribbon or a thread, which then continues into the edge of the flanges.
  • the weld seam continues on the outer edge of the flanges and is torn off after the two layers of the gripping tab have been delaminated.
  • the radial distance of the upper section of the part of the tear line running in the region of the gripping flap from the weld seam with respect to the center of the cover is 0.5 to 3 mm, preferably 1 to 2 mm, in a preferred embodiment.
  • a particularly practical embodiment had a distance of 1.5 mm between this upper section of the tear line and the weld seam on the far outside of the gripping tab. This distance can also continue in the edge of the flanges.
  • the gripping tab can be easily torn off, and yet the aforementioned projection remains on the cover flange, so that after removal of the Connection strip of the lid can logically and easily be removed from the cup-shaped lower part.
  • a particularly low-strength tear-off process results in the form of seams which are curved in a plan view of the packaging and which run continuously in the mathematical sense.
  • the gripping tab has an area of 1 cm 2 to 7 cm 2 , preferably 2 to 5 cm 2
  • the one connected to the lower layer with the connecting strip removable handle part of the gripping tab has an area of about 1 to 4 cm 2 .
  • an area of 2 to 3 cm 2 has been chosen for this grip part of the gripping pocket, so that this grip part lies well between the thumb and index finger of the user and thus not only easily and properly tears off the gripping tab but also the entire connecting strip leaves.
  • Figure 1 is a perspective and schematic of a package for liquid and / or solid
  • FIG. 3 shows a top view of the lid of the packaging according to FIG. 2, broken off, grip tab, in which the weld seam and the tear line are indicated, FIG.
  • FIG. 4 shows a representation comparable to FIG. 2, but in which the gripping tab has already been partially torn off

  • FIG. 1 shows a preferred embodiment of a packaging for liquid and solid filling goods, for example a margarine packaging. It consists of a cup-shaped lower part 1 with a circumferential upper flange 2 and a cover 3 with a circumferential flange 4. Both parts consist of 60% polypropene filled with plaster or chalk, a reprocessable, thermoformable and sealable plastic. The mutually facing surfaces of the flanges 2 and 4 are therefore made of plastic and are connected to one another via the weld seam 5 which is shown in FIGS. It can be seen that the weld seam according to FIGS. 2 to 7 is represented by a dash-dotted line.
  • the weld seam 5 creates a connecting strip 6, which is delimited by the aforementioned weld seam 5 and a tear line 7 in the form of a weakening line.
  • the weld seam 5 is on the outside, while the tear line 7 is at a distance a of e.g. 1, 5 mm is arranged radially inside.
  • the gripping plate 9 is made up of two layers, the lower one of which is made in one piece with the cup flange 2 and the upper one is made in one piece with the cover flange 4.
  • the weld line 5 shown in dash-dot lines runs across the gripping pocket 9 to close to its edge 10 and then following the edge 10 to the tear-off end 11. From there it continues (the tear-off direction in the figures is the clockwise direction - if you look at the packaging from above) in the weld 5 already described, which connects the two flanges 2, 4 to one another.
  • the tear line 7 shown as a dashed line in the figures follows the course of this weld seam 5 in parallel at a distance a if one runs around the entire pack in a clockwise direction from the tear-off end 11 and then from top to bottom as shown in FIGS a first separation point 12 comes. This is where area b of the gripping tab 9 begins. From this first separation point 12, the tear line is divided into two sections 13 and 14. The lower section 13 of the tear line extending in area b of the gripping tab 9 is shown as a line of dense points. Before the gripping tab 9 is torn off, this line is straight. It runs from the first separation point 12 to the tear-off end 11.
  • the upper section 14 of the tear line 7 running in the region b of the gripping tab 9 is shown as a broken line with crosses.
  • the lower section 13 of the tear line runs in the layer on the cup flange 2 along the boundary between the cup flange 2 and the gripping tab 9, which is why this lower section 13 is shown straight, because in the embodiments shown here this limit is straight.
  • the upper section 14 runs in the layer on the cover flange 4, in the first embodiment according to FIGS. 2 to 4 in an arc shape (in the embodiment according to FIGS 5 to 7 trapezoidal) to the outer edge 10 of the gripping tab 9.
  • this upper section 14 then again approaches the flanges 2 and 4 and opens at the tear-off end 11 mentioned into the weakening tear line 7 according to both flanges 2 and 4
  • the first tearing off of the gripping tab 9 shows from the illustrations in FIGS. 4 and 7 that the gripping tab 9 is divided into the front two-layer handle part 15 and the rear, delaminated part 16 separated from the upper section 14 of the tear line.
  • this part is only delaminated after tearing off, ie in the state of FIGS. 4 and 7, because then the two layers of the gripping tab 9 separate from one another in this delaminated part 16.
  • the projection 17 formed on the cover flange 4 remains in the upper layer.
  • a wedge-shaped line 18, which narrows to a tip 19, can be seen particularly clearly from FIGS. 5 and 6.
  • This line extends from the outer end point 20 to the first separation point 12 and has previously crossed the weld seam 5, as can be clearly seen in FIGS. 4 and 7.
  • the user grips the grip part 15 of the gripping tab 9 between the thumb and index finger and tears downward, as shown in FIGS. 4 and 7.
  • the tear line 7 extending in area b of the gripping tab 9 begins to separate from the first separation point 12.
  • the projection 17 forms on the cover flange 4.
  • the connecting strip 6 is formed, which can be completely torn off around the circumference of the packaging when the gripping tab 9 is pulled clockwise. Then the user can easily lift the lid 3 by gripping the projection 17 and open the packaging.
