.sctn.371 of International Patent Application No.
PCT/EP2011/002534, filed May 20, 2011, and claims the priority of
German Patent Application No. 20 2010 007 121.6, filed May 21, 2010
both of which are incorporated by reference herein in their
entirety. The International Application published in English on
Nov. 24, 2011 as WO 2011/144356 under PCT Article 21(2).
FIELD OF THE INVENTION
[0002] The invention relates to a packaging container and an
appropriate blank therefore. A swivel joint line is arranged along
a joining edge of the rear walls of the bottom and lid parts for
pivotably connecting both parts. The invention includes a locking
means provided at the bottom and at the lid parts for releasably
closing the packaging container.
BACKGROUND OF THE INVENTION
[0003] A packaging container is known in practice for storing fast
food like hamburgers or similar products. Generally, to remove the
fast food, a lid part is swiveled upwards relative to the bottom
part, so that the content of the packaging container is accessible
for removal. Such a container is described in EP 1 785 359 A1.
Sometimes, the user of such a packaging container would like to
consume the fast food directly from the container without taking it
out of the container.
[0004] JP 2003 072 749 A discloses a packaging container with a
bottom part and a lid part, wherein each of those parts comprises a
swivel joint for folding a half of the lid or bottom part upwards
or downwards. In this way, the packaging container may be opened
without taking the fast food out of the container.
[0005] JP 2002 347 756 A discloses a further container for solid
food that has a bottom and a top, with the top comprising two flaps
that can be locked to each other to close the upper opening of the
container. Essentially, in the middle between the top and bottom,
there is a angular, tearing working part that enables an upper half
part of the container body to be removed, such that the solid food
can be eaten directly from the lower half part of the
container.
SUMMARY OF THE INVENTION
[0006] It is an object of the present invention to provide an
improved container that can be used for consuming the food as long
as possible directly from the container, and to also allow easy
access to the food, even if it is already partly consumed.
[0007] According to the invention, at least one tearing line for
separating the bottom part and lid part is formed perpendicular to
the swivel joint line in the front walls, rear walls, and bottom
and top walls of the bottom part and the lid part of the
container.
[0008] According to JP 2003 072 749 A, the corresponding pivotable
halves of the lid and the bottom part are always connected to the
rest of the container. Even if it is possible to partially consume
the food directly from the container, those pivotable halves are
still connected to the container, and are an obstacle to the user
during eating the food. Moreover, those pivotable container halves
are not fixed in their open position and may fall back in direction
of the food, such that they have to be held by the user. As the
corresponding food may have ingredients that adhere to the
pivotable container halves, there is also a danger of contaminating
the users hands or clothes during consumption.
[0009] The container according to JP 2002 347 756 A is a container
that has no pivotably connected container halves, but will just be
divided more or less in the middle of the standing container. This
allows the user to consume about half of the food from the
container. The other half is then to be taken out of the container,
which might be difficult since the corresponding container opening
is quite close, and the user has to use his fingers to remove the
rest of the food, wherein his fingers have to be introduced between
the food and the edge of the opening.
[0010] According to the present invention, the packaging container
is divided by using the tearing line such that two container halves
are obtained, each of which is quite similar to the complete
packaging container and only has a lateral opening. This lateral
opening is used to remove one of the container halves and to use
the other container half to consume the food directly from this
container half. Moreover, the container half in use still comprises
a portion of each of the bottom part and the lid part, and also a
portion of the swivel joint line, such that the corresponding
portions of the bottom and lid parts may still be opened to take
out the rest of the food if it is no longer possible to consume
same directly from the corresponding container half.
[0011] It is even possible to close the remaining container half if
the user does not want to completely consume the food, but to take
it away for later consumption. There are no parts of the container
that are an obstacle with respect to consumption, or that make it
difficult to take out the rest of the food when it can no longer be
consumed directly from the container.
[0012] To allow an easy opening and closing of each of the
container halves mentioned above, it might be considered as
advantageous if two locking means are spaced with respect to each
other with the tearing strip therebetween. In this way, each of the
corresponding container halves can be opened or closed in a simple
way. Also the closing of each container half might be important for
further storing the food for later consumption.
[0013] It is also possible that there is only one locking means in
particular at the remaining container half. This locking means
allows an easy opening of this remaining container half to take out
the rest of the food which cannot be further consumed through the
corresponding lateral opening of this remaining container half. A
corresponding locking means is not necessary for the removed
container half.
[0014] To increase the stability, and particularly the shape
stability of each container half, the side walls of the bottom part
and/or the lid part may be concavely curved or rounded between the
front and the rear walls. By such concave curvature, each of the
container halves is stabilized, and each may be used for consuming
the food directly from the container half. Furthermore, this
concave curvature of the side wall forms some indentation or
recessed grip that can be used for at least some of the user's
fingers to support the container half or to hold the container
during removal of one container half. It might be possible that
such concave curvature is only provided on one side of the
packaging container, such that only one of the container halves
after using the tearing line will have this concavely curved side
walls. To avoid a definite selection of one of the container halves
for consumption of the food, it is advantageous for both of the
corresponding sides of the packaging container to comprise such
concavely curved side walls.
[0015] The corresponding effects as described will be even more
enhanced if upper and/or lower edges of the side walls of the
bottom and/or lid parts are convexly curved or rounded.
[0016] To allow an easy usage of the tearing line, the tearing line
can comprise a handheld portion at at least one end of the
line.
[0017] It is further possible that there is a second tearing line
which extends along the first tearing line defining a tearing strip
between the two tearing lines. This tearing strip may be removed in
total using both of the limiting tearing lines.
[0018] It is possible, that the first and the second tearing line
obliquely extend relative to each other. In such a way, the tearing
strip will change its width, wherein the smallest part of the
tearing strip may be used for starting the removal.
[0019] It is further possible, that the first and second tearing
lines are parallel to each other, such that the tearing strip has a
constant width.
[0020] It is possible to provide a corresponding tearing strip or
tearing lines that are separated from the rest of the container by
cut lines that extend along the tearing strip or lines and are
separated from each other by quite a short distance. The tearing
strip or lines are then removed or used by tearing the material
between the cut lines, wherein the direction of the cut lines
defines lateral edges of the tearing strip or lines.
[0021] However, such cut lines may also comprise openings that
might allow leakage of some of the food's ingredients and may, of
course, deteriorate the outer appearance of the container and might
also contaminate the user and, particularly, his clothes.
[0022] To prevent this, the tearing strip or lines can have lateral
edge portions extending at least in places from the strip or lines,
and there can be overlapping connecting edge portions of the top
wall, rear walls, front walls, and bottom wall, wherein said edges
are releasably fixed to each other. According to the overlap of
these edges, there is no direct opening of the container, and any
leakage from inside the container is prevented.
[0023] For removing the tearing strip or during use of the tearing
lines, the corresponding fixing of these edges is released. The
tearing strip may be removed in total.
[0024] It is possible that the tearing strip or lines are fixed to
edge portions of the corresponding walls. However, to avoid any
protrusion of the tearing strip or lines from the corresponding
walls, the lateral edge portions of the tearing strip or lines
and/or the overlapped connecting edge portions of the walls have a
reduced thickness of material. In this way, the added thickness of
lateral edge portions and connecting edge portions is rather
small.
[0025] It might further be considered as advantageous if the
lateral edge portions of the tearing strip or lines and the
overlapping connecting edge portions of the corresponding walls
have the same width. In this way, there will only be an overlap
between the outer edge portions and the connection edge
portions.
[0026] It is further possible that the lateral edge portions of the
tearing strip or lines and the overlapped connection edge portions
of the walls together have the same thickness of material as the
rest of the tearing strip/lines and/or walls. In such a way, the
tearing strip or lines will not protrude from the packaging
container.
[0027] There are different possibilities for releasably fixing the
edge portions, wherein one possibility is to glue the edge portions
to each other. However, if gluing is used, the tearing strip has to
be assembled separately. To avoid such separate assembly of the
tearing strip, it is possible that the lateral edge portions and
the connection edge portions are defined by partially impressed cut
lines that are separated from each other. Those only partially
impressed cut lines prevent any leakage and, at the same time,
allow easy removal of the tearing strip. Any gluing is not
necessary, as the tearing strip is an intrinsic part of the rest of
the container and is only defined by such partially impressed cut
lines. An easy arrangement of the cut lines might be considered,
according to which they are parallel to each other and are
impressed from upper and lower surfaces of the corresponding
tearing strip or container walls. It is also possible that they are
not strictly parallel or even have a structure such as a zig-zag
structure or the like. This is also valid in view of the tearing
lines, see in particular the partially impressed cut lines.
[0028] To facitate closing one or both of the container halves
after separating them by removing the tearing line, the locking
means may comprise a locking slit and a locking lug.
[0029] In case only one locking means is used (it is possible to
use two or more locking means on the container of the invention),
it may be advantageous if this locking means is provided at the
remaining container half such that this remaining container half
used for consuming the food may then be opened to consume also the
rest of the food within this remaining container half.
[0030] The locking lug may protrude from an upper edge of the front
wall of the bottom part with the corresponding locking slit
arranged along a folding line between the front wall and the top
wall of the lid part. The opposite arrangement is also
feasible.
[0031] To allow easy insertion of the locking lug and
simultaneously prevent any easy release of same, the locking lug
may have lateral locking extensions, wherein the length of the
locking lug with locking extensions corresponds to a length of the
locking slit with lateral cut lines of the slit. The lateral cut
lines, together with the locking slit are then used for introducing
the locking lug with its locking extensions, wherein those locking
extensions will avoid any easy release of the lock, as the length
of the locking slit more or less corresponds only to the length of
the locking lug without the locking extensions.
[0032] The lateral cut lines of the locking slit may be formed by
cut lines formed in folding lines between the front wall and top
wall.
[0033] All the other folding lines between other walls may comprise
such cut lines that are separated from each other with impressed
line sections therebetween.
[0034] To maintain the three dimensional structure of the packaging
container in an easy way, fixing lugs may be arranged at lateral
ends of at least the rear walls and/or the front walls of the
bottom and/or lid parts. The fixing lugs are glued to interior
surfaces of adjacent side walls.
[0035] To securely close the container and to further stabilize
same, the front walls and/or side walls of the lid part of the
bottom part may at least partially overlap the front wall and/or
side walls of the bottom part, or the lid part, respectively. The
opposite arrangement is also possible.
[0036] To allow easy access to the handheld portion, the front wall
of the lid part may have cutouts adjacent to the handheld portion
of the tearing strip.
[0037] According to one embodiment of the present invention the
front wall on both sides of the at least one tearing line may have
front wall sections of different lengths. The front wall section
with the longer length may then be used for removing one of the
container halves by separating same along the at least one tearing
line.
[0038] It might also be advantageous if the front wall section with
the longer length is curved at one edge in direction to the at
least one tearing line. This particular curved edge may then be
used as some kind of hand held portion during separation of the
container halves along the tearing line.
[0039] According to the invention, the simple two-dimensional blank
can be used for forming the packaging container as mentioned above.
Such a blank can comprise two bottom panels, two top panels, four
rear and four front wall panels, wherein pairs of the panels are
separated by the at least one tearing line. The two bottom panels
form the bottom wall of the bottom part, and the two top panels
form the top wall of the lid part. Each of the corresponding parts
also comprises two rear and two front wall panels that are all
separated by said tearing line.
[0040] The tearing line extends essentially perpendicular to the
folding lines, connecting bottom and front panels, bottom and rear
panels, rear and top panels, and top and front panels. As already
outlined, any folding may be simplified when each folding line
comprises a number of cut lines that are separated from each other
along the corresponding folding line, with impressed line sections
therebetween.
[0041] The tearing line is already formed in the blank, wherein
this blank comprises a partially impressed first cut line that may
be formed in an upper surface of the blank, and a partially
impressed second cut line that may be formed in the lower surface
of the blank. Those cut lines are separated parallel from each
other and define the tearing line therebetween. It is further
possible to arrange a second tearing line extending along the first
tearing line defining a tearing strip therebetween. With respect to
those two tearing lines it is possible that they are arranged in
parallel to each other.
[0042] First and second cut lines are then arranged in pairs at
both lateral edges of the tearing strip and define the lateral edge
portions and overlapped connecting edge portions that were already
mentioned.
[0043] The folding lines connecting side panels and bottom panels,
or side panels and top panels, may be concavely curved.
Furthermore, the end edges of the side panels adjacent to the top
panels may be convexly curved.
[0044] To provide any possible user of the container with some
reward it is possible to arrange at least one removable card in one
of the panels of the blank. This card may have some printing or
other index on an inner surface directed to the inner side of the
container and may be removed for collection or for receiving some
present.
[0045] It is also possible to arrange a number of such cards in one
container.

packaging container according to the present invention.
DETAILED DESCRIPTION OF THE INVENTION
[0053] In FIG. 1, one embodiment of a packaging container 1
according to the present invention, is shown in a perspective view
from the top.
[0054] The packaging container 1 comprises a lid part 3 and a
bottom part 2, see also FIG. 2. Each of the parts 2, 3, comprise a
front wall 5 or 10, the rear wall 6 or 11, side walls 7, 8, or 12,
13, and a bottom wall 4, see the bottom part, or a top wall 9, see
the lid part.
[0055] There are locking means 14 and 16 that are separated from
each other with a tearing strip 15 therebetween for closing the
container and locking same in the closed position. This tearing
strip 15 extends through front wall 10, top wall 9, the rear walls
6 and 11, see FIG. 2, the bottom wall 4, and the front wall 5 of
the bottom part, see again FIG. 2. The strip is defined by a first
and a second tearing line 62, 63, which extend in parallel to each
other.
[0056] The locking means 14, 16, each comprise a locking slit 33 or
34, and a counterpart 35, 36, in the form of a locking lug. The
locking lug protrudes from an upper edge 37 of the front wall 5 of
the bottom part 2. They are inserted in the corresponding locking
slits 33 and 34, in the case of a close position of the packaging
container 1, see FIG. 1.
[0057] Most of the walls are planar. However, the side walls 7, 8,
and 12, 13, are concavely curved in direction of the interior of
the packaging container 1. At least the upper and lower edges 17,
18, of the side walls 12, 13, of the lid part 3 are convexly
curved, such that in the case of a closed packaging container, see
FIG. 1, the corresponding side walls 12 and 13, and also 7 and 8 of
both parts 2, 3, are concavely curved into the interior in two
directions perpendicular to each other, see the height direction
and width direction of the side walls.
[0058] The tearing strip 15 is defined by a number of cut lines
27-30, see FIGS. 1 and 2, which define lateral edge portions 21 and
22 of the tearing strip 15 and complimentary connecting edge
portions 23 and 24 of the top wall 9, which are overlapped by the
lateral edge portions 21 and 22.
[0059] In FIG. 2, the packaging container according to FIG. 1 is
illustrated in an open position. The cut lines 27-30 are partially
impressed into upper and lower surfaces 31 and 32 of all of the
walls to define the tearing strip 15 and the corresponding edge
portions 21-24.
[0060] On the lower surface 32, see FIG. 2, there are only cut
lines 28 and 30, and on the upper surface 31, see FIG. 1, there are
the other cut lines 27 and 28. The cut lines 27 and 28 are arranged
parallel to each other and to the other cut lines 28 and 29,
wherein there is a small distance between each of the cut lines 27
and 29, or 28 and 30. The cut lines 28 and 29 are arranged in a
greater distance from the tearing strip 15 than the further cut
lines 27 and 28. The width 25, 26 of corresponding edges 21, 22,
and 23, 24 is the same.
[0061] For gripping the tearing strip 15 and removing same, -a
handheld portion 19 is provided at one end 59, see in particular
FIGS. 1 and 3. To more clearly define this handheld portion 19,
there are cutouts 44 directly adjacent to the handheld portion,
wherein those cutouts 44 are formed in the front wall 10 of the lid
part 3.
[0062] According to FIG. 2, the corresponding locking lugs 35 and
36 have lateral locking extensions 38 that are hook-like and are
also inserted in the corresponding locking slits 33, 34. Those
locking slits are continued with lateral cut lines 40 that are
arranged at both longitudinal ends of the corresponding slit 33,
34, see also FIG. 4.
[0063] Fixing lugs 43 are provided that extend from end edges of
front walls 5 and 10, and rear walls 6 and 11 to fix the front wall
or the corresponding rear wall with the adjacent side walls. Those
fixing lugs 43 are affixed to interior surfaces of corresponding
side walls 7, 8, or 12, 13, by applying an adhesive.
[0064] Along an upper edge of the two rear walls 6, 11, the walls
are connected to each other by swivel joint line 20 for pivotably
connecting the bottom part 2 and the lid part 3 of the packaging
container.
[0065] According to the embodiment of FIG. 2, upper edges of the
side wall 7, 8, of the bottom part of the packaging container are
not convexly curved, but are straight edges. In the closed position
according to FIG. 1, the side walls 12, 13, of the lid part 3 and
the front wall 10 of the lid part 3 overlap corresponding side
walls 7, 8, and front wall 5 of the bottom part 2.
[0066] In FIG. 3, the packaging container according to FIGS. 1, 2,
is illustrated with a removed tearing strip 15 and bottom part and
lid part 2, 3, separated in two halves of the packaging container
1. Each of the container halves comprises half of the bottom part
and half of the lid part, and also one of the locking means 14 or
16, respectively. Accordingly, each of the container halves is
releasably closed and can also be opened, see FIG. 2.
[0067] Tearing strip 15 also has folding lines 42, see also FIG. 4,
which connect walls of bottom part and lid part, see also FIGS. 1
and 2.
[0068] Moreover, the tearing strip 15 has lateral edge portions 21
and 22, which are reduced in thickness with respect to the rest of
the tearing strip. The container halves, according to FIG. 3, have
complimentary connecting edge portions 23 and 24 at the outer
surface that extend along the separation lines of the container
halves. Also, these connecting edge portions 23 and 24 are reduced
in material thickness, wherein the combination of one lateral edge
portion and corresponding connection edge portion have the same
material thickness as the rest of the container material. The edge
portions are defined by the cut lines 27-30 that were already
mentioned above. The cut lines 27 and 28 are partially impressed
from the outer surface of the container, and the cut lines 29 and
30 are partially impressed from the inner side of the container,
see again FIGS. 1 and 2.
[0069] In the separate position according to FIG. 3, it is possible
to consume fast food or the like within the packaging container
from one container half, wherein the other container half may be
disposed.
[0070] After the fast food has been consumed as much as possible
from the remaining container half, it can be opened, and the rest
of the food can be removed for manual consumption. It is also
possible to keep one container half with the rest of the food for
consumption later.
[0071] The packaging container according to the invention can also
be used for providing two fast foods, one in each container half,
wherein this packaging container is some kind of partner container.
After buying the partner container, it can be separated, and two
people can share the containers contents, wherein each person gets
one container half.
[0072] It is also possible to arrange different food in the
container halves that may then be consumed separately by one or two
people.
[0073] The containers material is paper or cardboard or another
recyclable material. It is possible to impregnate such material or
apply some fluid tight material to the surfaces, such as
corresponding resin layers. It is also possible to print
advertisements or other things on the exterior of the container.
Moreover, the tearing strip can be used as some kind of
gratification or the like with printing on its inner surface,
wherein the collection of a number or such tearing strips 15 may be
rewarded by some present from the seller.
[0074] In FIG. 4, there is a blank 45 as a single blank for
producing the container according to FIGS. 1 to 3. The blank 45
comprises a number of panels 46-56, which form corresponding walls.
For example, top panels 47 and 48 with the tearing strip 15
therebetween form the top wall 9 of the lid part 3. Front panels
51, according to FIG. 4, form the front wall 5 of the bottom part
2.
[0075] Folding lines 42 are arranged between all of the different
panels, wherein each of the folding lines 42 comprise cut lines 41
that are separated from each other along the folding lines 42. The
side panels 55 and 56, see also side walls 12 and 13 according to
FIG. 1, have convexly curved end edges 57 and 58. Corresponding
side panel fixing lugs 43 are arranged at both ends. Those are
later connected to the inner surface of the side panels 55 and 56,
see also FIG. 2. Fixing lugs 43 are also arranged adjacent to
lateral ends of side panels 53 and 54, which form the side walls 7
and 8 of the bottom part 2. The corresponding fixing lugs are fixed
to inner surfaces of said side panels, see again FIG. 2.
[0076] The two locking slits 33 and 34 are arranged along the
folding lines connecting the front panels 52 and top panels 47 and
48. They are continued in longitudinal direction by adjacent cut
lines 40. Length 60 of such a locking slit 33 or 34 with the
lateral cut lines 40 correspond to the length 39 of a locking lug
35 with lateral locking extensions 38. This length is used for
introducing the locking lugs with locking extensions.
[0077] The tearing strip 15 divides the blank 54 into two halves
that are symmetrical to each other. In FIG. 4, a view on the inner
surface of the corresponding blank 45 or the container according to
FIG. 2 is illustrated. In this view, the tearing strip 15 is
defined by partially impressed cut lines 29 and 30, which define
inner ends or lateral edge portions 21 and 22 of the tearing strip
15. On the outer surface or top surface of the blank 45, see also
the container according to FIG. 1, there are two further partially
impressed cut lines 27 and 28 that define ends of corresponding
connecting edge portions 23 and 24. The edges overlap each other
and together have the same material thickness as the rest of the
blank.
[0078] The rear walls 6 and 11 of bottom and lid parts 2, 3, are
each formed by a pair of rear panels 49 and 50, respectively. At
the ends of those rear panels, fixing lugs 43 are arranged, wherein
such lugs are also arranged at longitudinal ends of front panels 51
and 52.
[0079] The folding lines 41 between each of the side panels 53 and
54 and the adjacent bottom panels 46, are all convexly curved in
direction to the bottom panel, see the other folding lines 41
between the side panels 55 and 56, and top panels 47 and 48,
respectively. The swivel joint line 20, see FIG. 2, is formed by
folding line 42 between the different rear panels 49 and 50 of the
bottom part 2 and the lid part 3.
[0080] In FIG. 5 a blank 45 for a second embodiment of a packaging
container according to the invention is illustrated.
[0081] Parts of these blanks similar to the blank of FIG. 4 are
indicated by the same reference numbers and are also referred to
the corresponding description with respect to FIG. 4.
[0082] In the following only some differences of the two blanks
according to FIGS. 4 and 5 are outlined.
[0083] The main difference is the arrangement of only one tear line
62 which is used for separating the two container halves, see also
FIG. 3. It is not necessary to remove a corresponding tearing strip
15 but by gripping corresponding handheld portion 19 as part of one
of the front panels 52 the corresponding container halves can be
separated. The corresponding front panel 52 with the handheld
portion 19 has a longer length compared to the other front panel
52, which two front panels 52 are separated by the first tearing
line 62.
[0084] A corresponding edge connecting the front panel 52 with the
handheld portion 19 to the other front panel 52 or to the first
tear line is curved.
[0085] In both of the front panels 52 two removeable cards 64 are
arranged. Those are connected to the front panels by some cut lines
41 and lateral perforated removal lines 65.
[0086] Each of the corresponding cards may have some printing on
its inner side and this printing may be used for getting some
reward from the seller of the container, wherein it is also
possible to first collect a number of those cards before such a
reward may be obtained.
[0087] Alternatively, cards can be used as identifying tabs to be
folded by the personnel at the selling point, and in order to
identify flavor or type of food inside the container.
[0088] It is also possible that only one locking means 14, 16 is
used, see also FIG. 1, comprising a corresponding locking lug and
locking slit. In case only one locking means is used this is
advantageously arranged in the remaining container half, which
means the container half used for consuming the food after removing
the other container half. It is then easily possible to also open
this remaining container half to take out the rest of the food
which cannot be consumed through the corresponding lateral opening
of the remaining container half, see also FIG. 3.
[0089] It is of course also possible to use the locking means for
again closing this container half.
[0090] Moreover, depending on the user and if he is right-handed or
left-handed, it may be possible to arrange the handheld portion 19
at the other front panel 52 to allow the usage of the tearing line
62 with a preferred hand of the user.
[0091] Moreover, see also FIG. 1, the corresponding side walls 12
with the concave curvature are in particular used for supporting
the container by at least some fingers of the user not only during
consumption of the food after removing one container half, but this
sidewall is also used for holding the container during separation
of the two container halves. Moreover, during this separation it is
also helpful if other fingers of the user grip or hold the
corresponding rear wall 6 formed by the rear panels 49 and 50.
During this holding of the rear wall, it is possible that the
particular pairs of rear panels 49 and 50 are slightly pressed to
the inside of the container, in particular along the corresponding
swivel joint line 20, such that also the rear wall has some concave
form which will further improve the holding of the container, in
particular during the separation of the container halves.
[0092] This is of course also true in view of the other embodiment
of the present invention.
[0093] The particular packaging container according to the present
invention allows an easy separation of the container in two halves,
from which each half is closeable, wherein a corresponding tearing
strip or lines extend perpendicular to a swivel joint line between
the bottom and lid parts of the complete packaging container. The
tearing strip or lines surround the container, and it is easily
possible to remove the tearing strip or to separate the container
halves with the tearing line and then open the packaging container
by removing one of the container halves. The other container half
can be used for consuming food directly from said container half.
This container half can then be opened for removing the rest of the
food that cannot be consumed directly from the container. This
remaining container half can be closed again to keep the food for
consumption later.
[0094] Any spilling out of the container or leakage is prevented by
such a container, and it is also easily possible to remove the food
from the remaining container half.
