  • the advantage is to be able to quickly and safely close the enclosure, by a simple one push operation, once the content is filled into the packaging box, and thereby prevent any contamination to fall into the content enclosure. At the same time it is easy and safe to open the lid and get access to the content when this is an intended action.
  • a first side of the lid is connected to the upper side of a first side wall of the packaging box.
  • the packaging box is made out of a single die cut production template, for example from a cardboard template, and when mounted before filling the content into the packaging box it may be stored as a flat template, taking up almost no space.
  • the packaging box may be pre-mounted (and glued) (not shown) for manual filling in a popup-style packaging box.
  • a further alternative is to provide the lid as a standalone lid that may have protruding lips on all sides of the lid, and corresponding receiving recesses on all inward folded brim.
  • the packaging box may have three or more sides, although four sides may be most convenient, also when it comes to storing and transporting filled packaging boxes.
  • the first side of the lid is connected to the upper side of a first side wall of the packaging box and a tear line may be provided by perforated pattern (semi-cut) in the folding line between side wall and lid.
  • the lid When the lid is part of the die cut, it is connected to one of the side walls, it may be advantageous to make a tear line, by a perforated pattern in the folding line. This way is may be easier for a user to tear away the lid when accessing the content. If more than one side brim has a cooperating receiving recess and the corresponding lid sides having protruding lips, a user may still put the lid back, and it may stay firmly attached covering the opening.
  • the packaging box has four side walls, and the lid has four sides.
  • all non-connected sides of the lid comprise at least one protruding lip, and all corresponding side walls have on its upper end an inward folded brim comprising at least one receiving recess for receiving the corresponding protruding lip of the lid.

  • an easy to use and safe to handle packaging box is provided where any contamination is prevented from falling into the enclosure holding a content.
  • the aim is to provide a packaging box that can replace most plastic boxes used in consumer fresh food industries and takeaway industries, and which has many further area of use.
  • the brims may be pivotally and resiliently connected along a folding line to the corresponding side wall, and pivot easily inwardly and back .
  • This is an advantage for easily attachment of the lid that can simply be pushed down on top of the brim area. Then, the brim will give away at some degree, and the receiving recess 19 will be able to easily be penetrated by the protruding lip 19' of the lid 16. The resilient behavior will let the brim flex back once the protruding lip 19' enters the receiving recess 19.
  • a first side 24 of the lid 16 is connected to the upper side of a first side wall 12 of the packaging box 10.
  • the packaging box may be provided as a single production die cut template, for example from a cardboard template, and when mounted before filling the content into the packaging box may be stored as a flat template, taking up almost no space.

  • the present invention may also be provided in a two part configuration (not shown) wherein the packaging box and lid 16 is two separate items.
  • the packaging box 10 may then be provided in a semi assembled box being easily stacked, and with lids 16 being flat packed. When filling, then it will be simply to fill content, fold inward the brim areas, and click on the lid.
  • Figure 1 illustrates an advantageous embodiment of the present invention wherein the first side 24 of the lid 16 is connected to the upper side of a first side wall 12 of the packaging box 10 and a tear line 24' may be provided by a perforated pattern (semi-cut) in the folding line between side wall 12 and lid 16.
  • the lid When the lid is part of the die cut 100, 110, it is connected to one of the side walls, it may be advantageous to make a tear line 24', by for example a perforated pattern in the folding line. This way it may be easier for a user to tear away the lid when accessing the content. If more than one side brim has a cooperating receiving recess 19 and the corresponding lid sides having protruding lips 19', a user may still put the lid back, and it will stay firmly attached covering the opening.
  • the packaging box 10 has four side walls 12,13,14,15, and the lid has four sides 24,25,26,27, by tearing the lid after opening, it will still be possible to provide a locking of potential three sides when lid is put back, and provide a proper closing of the interior space.
  • the lid 16 comprises on one or more of the non-connected sides 25,26,27 one or more hold-back protrusions 17, the hold-back protrusions 17 being arranged to stop towards the top of the inward folded brim 21, 22, 23 and reach towards or over the top side of corresponding side wall 12,13,14,15, and thus prevent the lid 16 from being pushed into the enclosure when the protruding lips 19' of the lid 16 is inserted into the corresponding receiving recesses 19'.
  • the hold-back protrusions 17 further increase the stabling strength of the packaging box, such that more packaging boxes may be stabled/stacked upon each other before the bottom packaging box cave in, in the meaning of that the lid 16 is pushed into the interior space of the packaging box.
  • the configuration in the figures show such hold back protrusions 17 on all non-connected sides of the lid 16. Some is shown to reach as wide as almost to the peripheral end of the inward folded brim 21, 22, 23, and some reach out pass the side wall as seen in figure 3 . The latter is additionally provided to form a better grip on the lid for opening up when access to the content is required.
  • the size of the lid and the hold-back protrusions are preferably reaching at least as far out to each side that it spans at least half the width of the corresponding inward folded brim 21, 22, 23.
  • the protruding height ph of the protruding lips 19 are at least as long as it reach well past the outer end of the receiving recess 19' when the lid is arranged to close the interior space of the packaging box 10.
  • the inward folded brim 21,22,23 is configured to be flexibly bending 30 downwards when lid is pushed down 31 on the open end 18 such that the protruding lips 19' of the lid 16 is more easily inserted into the corresponding receiving recesses 19, and when protruding lips 19' are brought in position and gliding into the receiving recesses 19, the protruding lips 19' and recess 19 form a click lock function holding the lock 16 firmly in place.
  • the hold-back protrusions 17 ensures that the lid 16 will not be pushed into the interior space, and pressure may be applied to the protruding lips 19' to force the inward folded brim downwards, and the peripheral end of the protruding lip 19' will enter the receiving recess 19. When this happens, the inward folding brim will spring back and the protruding lip 19' will be locked in the receiving recess 19.
  • the hold-back protrusions 17 will provide a biased force to the protruding lips 19' such that these together will lift the inward folded brim 21, 22, 23 portions up towards the underside of the lid 16.
  • the lid 16 and the inward folded brims 21, 22, 23 therefore provide a tight locked combined "sealing" of the interior of the packaging box. If cold or warm content is packed, the heat or cold environment may be preserved for a considerable time. For example hot takeaway food, such as hamburger and fries, or cold takeaway, such as sushi.
  • FIG 4 and figure 5 it is shown an embodiment comprising one or more ventilation holes 41,42,45 provided in one or more of the bottom 11, the side walls 12,13,14,15 and the lid 16. These ventilation holes improve the interior environment for keeping fruit, berries, vegetables, and the like fresh.
