Definitions

  • the invention relates to a cup-shaped shell, which is unfolded from a one-piece cardboard blank and provided with a closure lid.
  • cup-shaped shells are either tightly closed and then difficult to open, or they are only covered by the lid and cannot be opened without authorization.
  • the invention has for its object to provide a shell of the type mentioned, which is firmly closed on the one hand and can be easily opened on the other hand.
  • closure lid is at least indirectly connected to the edge of the shell by sealing and is provided with a predetermined breaking line to facilitate tearing.
  • a shell designed in this way is - insofar as the material itself permits - absolutely tight and can nevertheless be opened very easily.
  • the edge outside the predetermined breaking line remains and stiffens the opened shell very effectively.
  • the upper edge of the shell is flanged into a horizontal position and the closure cover is flat and sealed to the edge of the shell, the predetermined breaking line lying within the sealing edge.
  • the edge remains when the shell is opened along the predetermined breaking line and stiffens the shell very well.
  • Another very advantageous embodiment of the invention lies in the fact that the upper edge of the shell is surrounded by a circumferential frame which is U-shaped in cross section and is sealed to the inside and / or outside by the edge.
  • This additional frame ensures a perfect seal between the bowl and lid.
  • the frame is provided with a closure cover which is connected to the frame at least on part of the frame circumference via a predetermined breaking line.
  • the closure cover is constructed in two layers, the inner layer being provided with a score line serving as a predetermined breaking line and the outer section divided by the score line being at least indirectly connected to the edge of the shell.
  • the scoring line is effectively sealed and can have a very strong weakening, which is very favorable for opening the shell.
  • FIG. 1 in FIG. 1 denotes a flat cardboard blank, which has a bottom section 2, to which a side wall section 5 or 6 is articulated via folding lines 3 and 4.
  • two end wall sections 7 and 8 are formed on the bottom section and are also connected to the side wall sections 5 and 6 via the folding lines 3 and 4.
  • Two further folding lines 9, 10 and 11, 12 each start from the two folding lines 3 and 4, through which gusset corners 13, 14, 15, 16 are divided between the side wall sections and the end wall sections.
  • These gusset corners 13 to 16 and the section of the respective end wall section 7 or 8 divided by the line 17 or 18 is provided on the outside and the inside with a sealable plastic layer, which is shown in FIG. 1 by hatching.
  • the two side wall sections 5 and 6 are first folded upward about the fold lines 3 and 4; then the two front wall sections 7 and 8 are bent upwards and the gusset corners and the end sections of the side wall sections are unfolded on the outside, whereupon all three layers are sealed together.
  • a cover 22 provided with a U-shaped edge 21 is placed on it, as shown in section in FIG. 3, and at least one leg of the U-shaped edge 21 is sealed to the walls of the shell.
  • the cover 22, including the edge 21, is deep-drawn from a plastic film and provided with a predetermined breaking line 23 within the edge, along which the cover can be torn open.
  • the entire cover surface 24 lying within the edge 21 is covered with a cardboard disc 25, which also covers the predetermined breaking line 23 and thus prevents any leaks in the area to be feared.
  • the cardboard disc 25 and the area 24 of the cover lying within the predetermined breaking line are glued to one another, so that when the cardboard disc is pulled up, this cover area is also removed.
  • the cardboard disc protrudes beyond the predetermined breaking line, it can be reinserted into the edge of the lid and, due to the support on the remaining section 26 of the lid surface, provides a sufficient seal.
  • a handle 27 molded onto the cardboard disc 25 facilitates both removal and reinsertion.
  • FIG. 4 shows a further flat cardboard blank 41, which also has a bottom section 42 and side wall sections 45 and 46 articulated thereon via folding lines 43 and 44, the folding lines 43 and 44 running in an arc shape and meeting at their respective ends.
  • the bottom section 42 is delimited by two fold lines 47 and 48, via which a gusset corner 49 and 50 is articulated, which on the other hand is delimited by two fold lines 51, 52 and 53.54.
  • These fold lines start from the outer corner points of the side wall sections 45, 46 and run to the opposite corner point of the bottom section 42, where they intersect at the tip of the respective gusset surface.
  • These fold lines 51, 52, 53, 54 are also cut by the fold lines 43 and 44, whereby further gusset corners 55 to 60 are formed.
  • the two gusset corners 59 and 60 are additionally halved by a fold line 61 and 62, respectively, which extends from the point of union of the fold lines 43 and 44 and the intersection of the fold lines 51 and 52 or 53 and
  • Two edge strips 65 and 66 are divided from the two side wall sections 45, 46 by fold lines 63 and 64, respectively, which are brought into a horizontal position and serve as a support for a cover.
  • a double-layered lid 67 is sealed onto the cup-shaped tray thus produced, which consists of a lower cardboard layer 69 provided with a predetermined breaking line 68 and an upper cardboard layer 70 connected to it, the upper cardboard layer covering the predetermined breaking line 68.
  • a scoring line 71 is provided in the upper cardboard layer 70, around which the lid detached along the predetermined breaking line can be folded up like a hinge. The edge of the lower cardboard layer 69 lying outside the predetermined breaking line 68 remains sealed at the edge 65,66 of the cardboard tray, because the sealing force between the two is chosen to be higher than the adhesive force between the two cardboard layers in this area.
