Definitions

  • the invention relates to a packaging for liquid and / or solid contents, consisting of a bowl-shaped lower part with an upper edge and a lid, the lid and at least the upper edge of the lower part made of plastic material and a first weld along the is attached to the upper edge of the lower part between the edge and the cover and for the formation of a tear-off strip towards the center of the cover runs a first tear line in the form of a weakening line on the strip-side edge of the first weld seam and a second tear line in the form of a distance from the first weld seam Line of weakness is arranged, which is provided around the entire upper edge of the lower part (US-A-3 515 334).
  • the shape of the lower part can of course also be understood as a cup, sleeve or plate.
  • bowl-shaped should be used representatively for these forms of lower parts.
  • plastic part in the sense of the present invention being understood to mean a sheet or sheet material.
  • the usual way of attaching a lid to a bowl-shaped lower part is all-round sealing, as is known, for example, from US Pat. No. 3,515,334. Similar to the packaging described in the introduction, the cover can also be removed in the known case by pulling off a tear-off strip from the edge of a lower part.
  • the first weld seam extends endlessly in the outer region of the edge circumference, and there is no second weld seam towards the center of the lid.
  • the tear strip is formed by two lines of weakness, one of which is located next to the weld mentioned and the other of which runs parallel to it at a distance.
  • the user grips a gripping tab and has to tear through the sealing seam with the attached first piece of the tear-off strip and then, following the endless lines of weakness, tear off the tear-off strip all around and remove the lid with it.
  • the lid material remains sealed to the flange only in the outer peripheral region, so that the inside of the packaging is accessible from the outside.
  • the disadvantage of this type of tear-off strip is that the gripping tab often separates from the actual tear-off strip when the opening operation is initiated because it tears off.
  • the adhesive force of the outer weld seam sometimes leads to this tearing.
  • the tear-off strip only partially detaches and delaminates. In both cases, opening the known packaging is then not possible.
  • the object of the invention is to improve packaging of the type mentioned in such a way that the tear force is reduced and delamination or even tearing off a gripping tab from the tear strip can be excluded.
  • the second tear line is formed along a portion of the first tear line along a second weld spaced apart from the first.
  • Packaging of the type described here can be used, for example, for foods that contain solid and liquid components at the same time.
  • the lid is made of weldable plastic material
  • such packaging can be inexpensively manufactured with simple means and is also easy to handle by the end user.
  • the cover can either be removed completely from the packaging using the tear-off strip or folded up like a hinge. In the latter case, the reclosure option is particularly simplified.
  • Such a pack is also suitable for transport and storage due to its good sealing and strength properties and is inexpensive for the end user.
  • first tear line runs on the strip-side edge of the first weld seam and the second tear line is formed at least along a first section of the first tear line by a separate weakening line in the first plastic part.
  • first weld seam it is also possible to form a separate weakening line so that it forms the first tear line. This labor and material expenditure is not necessary, because on the side of the tear-off strip the edge of the first weld seam also forms a tear line. If the user tears up the tear-off strip, it will separate along the strip-side edge of the first weld. This allows you to separate the first plastic part from the second part, be it hinged up or separate.
  • the tear-off strip has a The welded joint is connected to the upper edge of the lower part and if this welded joint preferably connects the first weld to the second weld.
  • the tear-off strip is then not completely separated and thrown away after being torn up, but remains attached to the edge of the lower part. This can be done using the above-mentioned welding booklet. This is a welding area of approximately 0.5 to 4 cm2, preferably 1 to 3 cm2. Alternatively, this welding tackle but also an extension of the first and / or the second weld, because according to the above teaching, the welded joint should create a connection between the two welds.
  • the first weld seam which is arranged on the outside with respect to the middle of the lid, is followed in plan view of the lid and the upper edge of the lower part of the packaging, then the first weld seam is interrupted in the handle tab area to be described; ie if you follow it from the beginning in the direction of tearing behind the grip tab to be described, it runs around the upper edge of the lower part to the mentioned welding tackle and ends there or is transferred to the second weld seam, provided that in the special embodiment one ( to form a hinge).
  • the first weld seam passes over the weld stitching point into the second weld seam and runs from the weld stitching point (still in the tear direction) at a closer distance to the center of the lid.
  • the first weld seam next to the welding tacking point for the tear-off strip is interrupted along a grip tab, the length of which is 0.5 to 3 cm, preferably 1 to 2 cm, seen in the tear-open direction.
  • This grip tab can even protrude beyond the outer edge of the lid edge so that the end user immediately recognizes the function of the grip tab.
  • the person skilled in the art could recognize that the inside of the package is not theoretically completely separated from the outside by a weld seam or a plurality of weld seams.
  • the cover is approximately square in plan view, with rounded corners also being conceivable, as a result of which four more or less straight edges of the same and / or different lengths are formed.
  • the two weld seams run at a distance from one another between the cover and the lower part such that, according to the invention, the first weld seam also extends from a first end of the grip tab all the way to its other second end runs. The first weld seam ends, so to speak, in the welding tack at this second other end of the grip tab.
  • the second tear line from the second end of the tab to the opposite end of the particular straight edge of the cover stripes along the second weld seam running there and then along the other three edges all around in one piece to the welding tack for the Tear strip stretches.
  • the tear-off strip sticks to the lower part due to its attachment to the welding tacking point after being torn up and forms when torn up by the two tear lines running parallel to one another, the first tear line being understood as being outside the center of the lid and the second tear line lying further inside.
  • the second tear line runs roughly like a beginning weft line, because one is there End located with respect to the center of the lid in plan view of the lid within the other end.
  • first weld seam which, starting from the first end of the grip tab in the tear-open direction, runs around the edge to the other second end of the grip tab and there in the embodiment with the second weld seam in the area of the weld tacking point to a narrower radius or a smaller distance from the center of the cover is diverted and transferred to the second weld seam, which in the area of the second section, which is practically also the area of the hinge, on the other side of the tear-off strip runs parallel to the first weld seam until the second weld seam stops at the hinge end and from there to the second tear line.
  • the course of the two weld seams can be regarded as approximately spiral, because the second weld seam is arranged within the beginning of the first weld seam.
  • the fastening device for packaging if the lower part of the pack or the so-called second plastic part is thicker and stiffer than the lid or the first plastic part.
  • the lower part is made of a 1.0 mm thick plastic material and the cover or the first plastic part is made of a 0.4 mm thick plastic material.
  • the lower part of the packaging and / or the lid is / are deep-drawn.
  • the packaging and the fastening device when used on such a packaging are particularly interesting in connection with two plastic films or sheets or sheets to be sealed, as already indicated above.
  • plastic materials preferably form in one piece the respective film, web or Sheet, which enables particularly reusable parts, such as packaging, to be created (in contrast to composite materials).
  • a particularly expedient plastic material is polypropene, which in turn can be filled in a particularly preferred embodiment, for example can be 60% filled. Fillers are chalk, mica, talc, plaster or the like. Such filled plastics are also deep-drawable and sealable. It has been shown that filled plastic materials are even more tearable.
  • a film made of plastic material which is generally larger in plan view and thicker in cross section in the drawings, is referred to here as second plastic part 2, which corresponds to the lower part 2 'of the same in the packaging shown in FIGS. 6 to 13.
  • a first plastic part 1 is to be attached to this second plastic part 2, which is the generally smaller film part in plan view and generally thinner in cross section.
  • the packaging according to Figures 6 to 13 is the lid 1 '.
  • These two plastic parts 1 and 2 or cover 1 'of the packaging and its lower part 2' are connected to each other by a first weld 3. This can be straight as in Figures 1 to 3 or curved and straight, as shown in Figures 4 and 6. Parallel to the first weld 3, ie in Distance a runs a second tear line 4.
  • the second tear line 4 runs at a distance a parallel to a first tear line 5, which is shown in FIGS. 2 and 15 by a broken line.
  • This first tear line 5 is formed on the edge of the first weld 3 lying towards the center 20 of the cover 1 ', because when the tear-off strip 6 located between the two tear lines 4 and 5 is torn up, it is automatically cut off next to the first weld 3. For this reason, the first tear line 5 runs in the strip-side edge of the first weld 3.
  • the second tear line 4 can be formed by a separate weakening line 7 in the first plastic part 1 or in the cover 1 ', so that when the tear-off strip 6 is pulled up, it is torn off along the second tear line 4, as shown by the dashed line in FIG. 15 or is also shown in Figures 3 and 13.
  • the second tear line 4 can also be formed by a second weld 8, which is located in a so-called second section 9.
  • the lower straight piece which adjoins it at the top within the double line without cross hatching is this first region 10, which is continued upward behind the bent region on the right into the second section 9 with the cross hatching.
  • first tear line 5 is formed here at the second weld seam, the second tear line 4 by the sharp edge next to the inner second weld 8 as well as on the strip-side edge.
  • the cover 2 ' is approximately rectangular in plan view with rounded corners. It has three straight edges 12 and a straight edge 12 ', which is on the left in FIG. 6 and tears open the second section 9.
  • this section i.e.
  • the two weld seams 3 and 8 are at a distance a from one another such that the hinge for the cover 1 'is formed in this second section 9.
  • the grip tab 14, the upper end of which is called the first end 15 is first arranged in the tear-open direction of the arrows 13. From this end 15 upwards in the direction of the left arrows 13, i.e.
  • the first weld seam 3 extends over the entire second section 9 then above the first curve to the right into the next straight side edge 12, at the top right again down into the next straight side edge 12 and at the bottom right in a clockwise direction along the curved arrow 13 into the lower straight edge 12, so that there is an extension all around the outer edge of the lid 1 'to the other second end 16 of the handle tab 14.
  • This second end 16 is located at the bottom left in FIG. 6 on the handle tab 14, ie with respect to the handle tab 14 opposite the first end 15 thereof.
  • the first weld seam 3 opens into a welding tack 17. It can be seen from FIG. 6 how the welding tack 17 extends over the distance a from the outside in, i.e. creates the connection between the first weld 3 with the second weld 8.
  • the opening process now takes place in such a way that the user grips the grip tab 14 and tears up the tear-off strip 6 in the direction of the arrow 13.
  • the sectional view along the line VIII-VIII in FIG. 6 then changes from the illustration in FIG. 8 to that in FIG. 9.
  • the state in the edge region along the line XX then changes from the closed state in FIG 11 when opened further.
  • the state in FIG. 12 then changes accordingly to that in FIG. 13.
  • the tear strip 6 is torn further in a clockwise direction and finally remains at the welding tack 17 hang. This forms in the second section 9 along the second weld 8 Hinge, around which the lid 1 'can be folded up as the axis of rotation and can be closed again after the packaging has been completely or partially emptied.
