Description
[0001] The invention concerns a packing bag of a flexible,
foil-like first material, with an opening part which is separable
along a tear line running transverse to the bag longitudinal
direction, and with a substantially form-stable outer packing of a
second material.
[0002] For portion packing of drinks and/or spoonable products such
as e.g. fruit juices, water or soups, rigid or form-stable plastics
containers are known, normally produced by 3D thermoforming or
injection moulding, with a sealed lid and stiff bag made from
plastic laminate. Such packing containers and bags are ecologically
harmful because of the increased material required to achieve
stability, and also relatively costly. In addition, the packaging
as an advertising carrier is usually printed directly and hence in
principle there is a risk of migration of undesirable substances to
the filling.
[0003] The invention is based on the object of creating a packaging
for drinks and spoonable products, e.g. fruit juices, water or
soups, also for products with liquid and solid constituents or
semi-solid products, e.g. animal feeds, which avoids or reduces the
disadvantages described above of the packaging according to the
prior art.
[0004] The object is achieved with a packing bag of the type cited
initially in that the openings of the tubular outer packing lie in
a plane perpendicular to the tube axis and the bag end protruding
from the outer packing, after separation of the opening part, with
its inside facing out, can be folded over the edge of the outer
packing.
[0005] In a preferred embodiment of the packing bag according to
the invention, the bag material is a plastics film. To prevent
migration of foreign matter to the inside of the bag, the packing
bag is not printed.
[0006] Preferably, the bag material and outer packing material are
mainly mono-materials.
[0007] The outer packing material can be any cheap mono-material. A
preferred outer packing material is cardboard. The outer packing
can be printed as required.
[0008] The outer periphery of the bag transverse to the bag
longitudinal direction is suitably larger than the inner periphery
of the tubular outer packing so that the bag is held in the outer
packing by interference fit. Instead of a larger outer periphery,
on the bag a separating line can be provided, which is torn when
folding over the edge of the outer packing.
[0009] The packing bag can have a peelable sealing seam parallel to
and at a distance from the tear line. This avoids the filling
reaching the top part of the bag prematurely, and when the bag top
is folded over the edge of the outer packing, coming into contact
with the outside of the opened packing. Alternatively the inside of
the packing bag can be coated with a release lacquer.
[0010] The cross-sectional shape of the outer packing is usually
circular. For reasons of attractive design, the periphery line of
the tubular outer packing can also be polygonal, e.g. with 4, 6 or
8 sides.
[0011] The dimensions of the packing bag and outer packing can be
varied within broad limits. The ratio between diameter or periphery
of bag and outer packing depends on the type of use and filling.
For a drink filling, the height of the bag will be larger than the
diameter. For a semi-solid filling, e.g. animal feed, the base
dimension or diameter of the packing will be larger than its
height. The packing bag is used merely to serve the filling and
need not be cleaned after use.
[0012] The stability of the packing bag arises from the outer
packing which can also be a beaker or cup. The packing bag itself
can be a standing bag without stability, a hose bag or an extruded
round bag, The bag material for the packing bag according to the
invention can, in comparison with the stiff material required for a
standing bag with stability, have a smaller thickness and
consequently is economic. The outer packing which is used as a
beaker or cup at the same time protects the delicate bag from
mechanical damage during transport.
[0013] The packing bag is suitable in particular for packing drinks
or spoonable fillings and for fillings which can be agitated with
fluid into drinks or spoonable fillings. The packing is also
suitable for animal feed. Depending on nature of filling, this may
also be agitated with fluid e.g. bag soups with hot water, or the
filling is already present in liquid or spoonable form, e.g.
yoghurt.
[0014] For water with and without carbonic acid, the packing system
serves to conserve the fluid and also acts as a drinking vessel.
For animal feeds and other semi-solid to solid products, the
serving function is a substantial advantage.
[0015] The food e.g. soup can be heated in the packing bag
according to the invention together with the outer packing in the
opened state, where applicable after agitation with cold water,
directly in a microwave oven.
[0016] Usually, individual packing units each comprise a packing
bag arranged in an outer packing. It is, however, also possible for
a packing unit to comprise for example five packing bags and only
one outer packing. Finally, packing bags intended for use with a
normal cup can constitute a packing unit even without tubular outer
packing.
[0017] Further advantages, features and details of the invention
arise from the description below of preferred embodiments and the
drawing which shows diagrammatically:
[0018] FIG. 1 an oblique view of a packing bag;
[0019] FIG. 2 an oblique view of a tubular outer packing;
[0020] FIG. 3 an oblique view of the packing bag in FIG. 1 inserted
in the tubular outer packing of FIG. 2;
[0021] FIG. 4 an oblique view of the arrangement in FIG. 3 with
separate opening part;
[0022] FIG. 5 an oblique view of the outer packing of FIG. 4 with
bag opening folded over the edge of the outer packing.
[0023] A packing bag 10 shown in FIG. 1 in the form of a standing
bag of a flexible foil material, e.g. polyamide, has a sealed base
12, a front wall 14 and a rear wall 16. Two longitudinal sealing
seams 18, 19 arranged at the sides and defining a bag longitudinal
direction l connect the two bag walls 14, 16 protruding from the
base 12 and, together with a transverse sealing seam 20 connecting
the longitudinal sealing seams 18, 19 at the end remote from the
base, form a closed packing bag 10.
[0024] The transverse sealing seam 20 at the end of the packing bag
10 remote from the base is part of an opening part 26 that can be
separated from the base. To open the packing bag 10, the opening
part 26 is torn away along a tear line 24 arranged in the bag walls
14, 16, parallel to and at a short distance from the transverse
sealing seam 20. As a tear aid, provided in the longitudinal
sealing seams 18, 19 are tear notches 22, 23 with tips ending on
the tear line 24.
[0025] Below the tear line 24, at a distance from and parallel to
the tear line 24, runs a further sealing seam 28 extending over the
entire width of the bag walls 14, 16, which seam is however
peelable i.e. along this peelable sealing seam 28, after separating
the opening part 26, the bag walls 14, 16 can be separated from
each other by hand without great force.
[0026] FIG. 2 shows a tubular outer packing 30 made from a
form-stable material e.g. cardboard, the ends of which lie parallel
to each other and vertical to a tube axis z. The outer packing 30
serves to hold the packing bag 10 of FIG. 1.
[0027] A packing unit comprising the tubular outer packing 30 with
packing bag 10 inserted therein is shown in FIG. 3. The
longitudinal direction l of the packing bag 10 lies in the tube
axis z of the outer packing 30. The one end of the tubular outer
packing 30 serves as a standing surface for the packing unit, so
that the packing bag 10 itself need not be formed stable. The
packing bag 10 can therefore also be a simple hose bag with one
longitudinal seam and two transverse seams.
[0028] The tubular outer packing 30 in the example shown is a
hollow cylinder but instead of a circular cross-sectional form,
another design is also possible. The peripheral line of the tubular
outer packing can for example take the form of a regular
polygon.
[0029] The outer periphery of the packing bag 10 is selected
greater than the inner periphery of the outer packing 30. For an
outer packing 30 in the form of a hollow cylinder, consequently the
inner diameter is smaller than the outer diameter of the packing
bag 10 formed into a bag with circular cross-section. Also the bag
walls 14, 16 for example can be partially attached by way of spot
adhesive points 32 to the inside of the outer packing 30. The
distance a of the peelable sealing seam 28 from the tear line 24 is
selected so that the peelable sealing seam 28 protrudes slightly
from the outer packing 30 when the packing bag 10 is inserted in
the outer packing 30.
[0030] After tearing away the opening part 26, the peelable sealing
seam 28 is separated by pulling apart the free ends of the bag
walls 14, 16 and the bag thus completely opened (FIG. 4). Then the
part of the opened packing bag 10 protruding from the outer packing
30 is folded over the outer packing 30 (FIG. 5). In this process
the insides of the bag walls 14, 16 are turned towards the outside,
giving a perfectly hygienic opening area.
[0031] The process of folding over the edges is made easier by the
fact that the outer periphery of the packing bag 10 is larger than
the inner periphery of the outer packing 30. Alternatively or
additionally, the longitudinal sealing seams 18, 19 of the part of
the packing bag 10 protruding from the outer packing 30 are
designed to be peelable. In this case on folding back the bag walls
14, 16, at the same time a partial or complete separation occurs of
the longitudinal sealing seams in this area.
[0032] The peelable sealing seam 28 prevents the penetration of
filling into the area between the peelable sealing seam 28 and the
tear line 26 in the unopened packing bag 10, so that even after
opening of the bag no filling adheres to the part of the bag
protruding from the outer packing 30 and turned towards the outside
when folded back.
[0033] On folding the bag part protruding from the outer packing 30
over the opening edge of the outer packing 30, a beaker is produced
with a perfectly hygienic opening area which can safely be brought
directly to the mouth.
