[0001] This invention relates to a package comprising a series of individual product packages,
the package comprising a tubular wrapper open at at least one and preferably both
ends, which wrapper abuts against the outside of the product packages. Such a package
is known from the Offenlegungsschrift DE 29 34 493.
[0002] Product packages such as cardboard boxes with, for instance, foodstuffs, consumer
products and the like are usually packaged in outer boxes. Such outer boxes are, for
instance, folded from cardboard blanks and comprise a bottom, four longitudinal walls
and a cover. The individual packages are densely stacked in the outer box, whereafter
the outer box is closed above the individual packages, so that the individual packages
are enclosed on all sides in the outer box.
[0003] Such a method of packaging individual product packages is unfavorable. Firstly, an
outer package of this known type requires relatively much material, while forming
it is relatively complicated and time-consuming. Further, the outer package must be
set up completely before the individual packages can be placed in it. In order to
obtain sufficient protection, a proper fit of a desired number of individual product
packages in the outer box must be obtained. As a consequence, it is not easy to get
the desired number of individual packages properly into the outer package. Moreover,
this means for a user that the individual packages cannot be easily taken from the
outer package, which is labor intensive and will lead to loss of time. A further disadvantage
is that the used outer packages will take up relatively much space, which is undesirable
for end use. Indeed, as a consequence, an end user will have to store and discard
relatively much waste material. A further disadvantage is that such an outer package
is environment-unfriendly, and that it is not at all times visible what kind of individual
packages are accommodated in it.
[0004] The invention contemplates a package of the type described in the opening paragraph
hereof, which obviates the above-described disadvantages thereof while maintaining
the advantages thereof. To that end, a package according to the invention is characterized
by the features according to claim 1.
[0005] A package according to the invention is substantially tubular, with the wrapper closely
fitting the outside of the individual product packages, arranged in at least one row,
while on the inside of the wrapper friction-increasing means are provided at least
adjacent the open ends thereof. This means that a package according to the present
invention abuts on four sides of the row of individual packages, such that the individual
packages are prevented from leaving the row without the wrapper being at least partly
removed. The friction-increasing means here ensure that any displacement of the individual
packages within the wrapper is prevented. The friction-increasing means are provided,
extending between an inner surface of the wrapper and an outer surface of the product
packages, and include means that do not adhere to the individual packages to such
an extent that the latter can only be detached by pulling or tearing them loose, with
the respective individual packages thereby being damaged, but do increase the friction
between the wrapper and the individual packages.
[0006] In a package according to the present invention, at at least one, and preferably
both, ends of the series of individual packages, an individual package can be viewed
from the outside of the package. A package according to the present invention requires
relatively little material and yet offers sufficient protection for the individual
products. The wrapper according to the present invention can be applied relatively
easily, for instance by providing it around the series of product packages after their
being arranged in the series.
[0007] In a first advantageous embodiment, a package according to the present invention
is characterized by the features according to claim 2.
[0008] The use of tearing means for opening the wrapper along the length thereof provides
the advantage that the individual packages can be taken out relatively easily, while
the package can be folded flat for storage and removal while requiring relatively
little space.
[0009] A package according to the present invention is preferably manufactured from cardboard
or a like sheetlike material.
[0010] In a second advantageous embodiment, a package according to the present invention
is characterized by the features according to claim 3.
[0011] The use of tearing means which are provided such that an upper part of the wrapper
can be removed provides the advantage that the bottom surface of the wrapper continues
to support the series of individual packages. The series of individual packages can
be shoved off the bottom surface of the wrapper, in parts or as a whole. Moreover,
the series as a whole is still transportable to, for instance, a display rack onto
which the series can be shoved or otherwise transferred.
[0012] In a third advantageous embodiment, a package according to the present invention
is characterized by the features according to claim 4.
[0013] The use of tearing means which are provided substantially parallel to the wrapping
direction provides the advantage that the tubular wrapper, which comprises a series
of individual product packages, is divisible into subpackages each comprising a subseries
of individual packages.
[0014] In a further advantageous embodiment, a package according to the present invention
is further characterized by the features according to claim 9.
[0015] Placement of the friction-increasing means along the entire length of the wrapper
provides the advantage that each of the individual product packages is in contact
with the friction-increasing means, thereby preventing individual product packages
from shifting relative to each other and/or the wrapper.
[0016] In a particularly advantageous embodiment, a package according to the present invention
is further characterized by the features according to claim 11.
[0017] The use of friction-increasing means comprising an adhesion-increasing component
provides the advantage that the individual product packages are held in place within
the wrapper still better. The friction-increasing means can provide a mechanical resistance
to shifting of the individual packages relative to the wrapper. In this case, the
resistance is often based on roughness of a friction-increasing surface, so that a
phenomenon known as interlocking of the contacting surfaces can occur. When the friction-increasing
means comprise an adhesive component, this is to say that the surface material of
the friction-increasing means is such that it exerts a force of attraction on a material
with which this surface is in contact. These friction- and adhesion-increasing means
can be manufactured such that no adhering bond arises between the individual packages
and the wrapper, so that upon detachment of the individual product packages from the
wrapper, the product packages are not damaged. Residues of friction- and adhesion-increasing
means are left behind practically entirely on the wrapper.
[0018] In another advantageous embodiment, a package according to the present invention
is further characterized by the features according to claim 12.
[0019] The use of friction-increasing means which comprise glue means provides the advantage
that the individual product packages are held in position within the wrapper much
better still.
[0020] In this case, a connection with the individual package, often chemical in nature,
is formed, requiring the connection to be broken by tearing it loose to effect relative
displacement of individual packages with respect to the wrapper.
[0021] Friction-increasing means in a package according to the present invention can be
designed, for instance, as pressure-sensitive or hot- or cold-melt adhesives, such
that when detaching the individual product packages from the wrapper the product packages
are not damaged and preferably no residues of the friction-increasing means remain
behind thereon.
[0022] The invention further relates to a blank for manufacturing a wrapper for use in a
package according to the invention, characterized by the features according to claim
18.
[0023] The invention furthermore relates to a method for manufacturing a package, characterized
by the features according to claim 19.
[0024] With such a method, for instance a package according to the present invention can
be obtained. Such a method provides the advantage that relatively fast and simply,
with relatively little material, a package for individual product packages can be
obtained, which has a good bundling capacity, is simple in use and yields comparatively
little waste.
[0025] Further advantageous embodiments of a package according to the invention are set
forth in the further subclaims.
[0026] To clarify the invention, exemplary embodiments of a package and method according
to the present invention will be further elucidated with reference to the drawing.

[0027] In this description, the same or corresponding parts have the same or corresponding
reference numerals.
[0028] In Figs. 1 and 2, there is shown a package 1 according to the invention, comprising
a series of identical, at least substantially identically shaped, individual product
packages 2, with side surfaces placed against each other for forming a series 4. A
wrapper 6, folded from a blank 7, such as shown, for instance, in Fig. 3, extends
along four sides of the series 4 of individual packages 2, and is disposed with a
proper fit against the side surfaces 8 on opposite sides of the series 4 and against
the top surfaces 10 and bottom surfaces 12 of the series 4 of individual packages
2. Accordingly, the wrapper 6 in a simple manner prevents shifting of the individual
product packages 2 relative to each other in lateral, upward and downward direction.
At the short ends 14A, 14B, the package 1, at least the wrapper 6, is open, such that
the end surfaces of the package 1 are formed by the end surfaces 16 of, respectively,
the first and last individual package 2 in the series 4. The length of the wrapper
6 corresponds substantially to the length of the series 4.
[0029] Fig. 3 shows in elevation a blank 7 for a wrapper 6. This blank 7 comprises a bottom
surface 18 with side surfaces 22A, 22B connected thereto through fold lines 20. Through
a first further fold line 24, parallel to the first fold lines 20, there is connected
with the side surface 22A a first top surface part 26, while through a second further
fold line 28, parallel to the first fold lines 20 and the first further fold line
24, a second top surface part 30 is connected with the respective side surface 22B.
The first top surface part 26 is provided along its free longitudinal edge with a
glue flap 32 which, when the wrapper is closed, can be glued to the side of the second
top surface part 30 then facing inwards. In this way, a closed wrapper 6 can be obtained.
The glue flap 32 is then preferably glued relatively fixedly to the second top surface
part 30, so that it cannot come loose therefrom. During gluing, the individual product
packages 2 are enclosed in the wrapper and used as press-on surface for the gluing
operation.
[0030] In the first top surface part 26 and the second top surface part 30, a perforation
line 34A, 34B is provided, which extend parallel to the first further fold line 24
and the second further fold line 28. With the wrapper in closed condition, the perforation
lines 34A, 34B are located at some distance from each other, with the part enclosed
between them forming a tear lip 36. On each fold line 20, 24, 28, on the side facing
inwards during use, throughout the length in the embodiment shown, there is provided
a friction-increasing means 38, for instance in the form of a hot-melt or cold-melt
adhesive, a pressure-sensitive adhesive or a rubbery means, such that, with individual
product packages 2 enclosed in the wrapper 6, a friction is thereby obtained, such
that especially the first and the last individual product package 2 in the series
4 are held in position, thereby enclosing the intermediate product packages 2 in the
series 4. In principle, it is also possible to provide such a friction-increasing
means at different points on the wrapper 6, as long as it also extends at least adjacent
the ends 14A, 14B of the wrapper 6, open in use, at least over a part thereof. It
is preferred, however, that the friction-increasing means extend adjacent the fold
lines throughout the length of the wrapper 6, in continuous or interrupted strips.
Retaining the product packages 2 adjacent the corners by means of the friction-increasing
means provides the advantage that the corners of the individual packages 2 are relatively
stiff and therefore can be more readily engaged without being damaged. Moreover, in
a simple manner this still further reduces the risk of damage to any advertising utterances
on the product packages 2.
[0031] As shown in Fig. 1, for opening the package 2, the tear strip 36 can be gripped adjacent
an end and be pulled up and away, such that it tears loose along the perforation lines
34A, 34B. After removal of the tear strip 36, the wrapper 6 can be unfolded, as shown
in Fig. 2. As a result, the individual packages 2 can be simply removed, individually
or in groups, for instance as a complete series. Such a series 4 can be placed simply
and directly in, for instance, a display rack. The wrapper 6 can subsequently be discarded
in flat form.
[0032] In a special embodiment, tear strips 48 can be provided in the two side surfaces
22A, 22B of the wrapper, as shown in Fig. 6. A part of the wrapper 1 is then removable
by tearing the two tear strips 48 from the side surfaces 22A, 22B of the wrapper 1.
Fig. 4 shows this situation, where the top surface 44 is separated from the bottom
surface 18 by tearing the tear strips 48 from the wrapper 1 along the perforation
lines 34A. The parts 40 of the side surfaces 22A, 22B then remain attached to bottom
surface 18 which supports the series 4. The parts 41 of the side surfaces 22A, 22B
then remain attached to top surface 44. The tear strips 48 and the top surface 44
are completely removable from the wrapper 1, so that series 4 is still in contact
only with the bottom surface 18, as shown in Fig. 5. An advantage is that the series
of individual packages is still displaceable as a series by using the bottom surface
18 as a series-supporting surface and using the parts 40, when pressed against the
side surfaces 8 of the individual packages 2 in the series 4, as an impediment to
lateral displacement, If the friction-increasing means are arranged on the insides
of the parts 40, then, when pressing the parts 40 against the series 4, the friction-increasing
means 39 on the parts 40 are in contact with at least the individual packages of series
4 situated at the originally open end of the wrapper. The series 4 is thereby hampered
in shifting in the longitudinal direction as well. When omitting such pressing-on,
the parts 40 unfold away from the series 4, so that the series 4, while being shoved
off part 18, will only experience friction from the friction-increasing means 38,
if any are provided, on the inside of part 18.
[0033] A blank 46 for a wrapper according to Figs. 4 and 5 is shown in Fig. 6. The blank
46 to a large extent corresponds to the blank according to Fig. 3. Blank 46 comprises
a bottom surface 18 with two side surfaces 22A, 22B connected thereto through fold
lines 20, the side surfaces being provided with a tear strip 48. A closed wrapper
can be obtained by fixedly gluing the glue flap 32 to the inwardly facing side of
a part 41 of side surface 22B. The friction-increasing means 38 are provided on the
inside of bottom surface 18 and top surface 44, for instance adjacent the ends. The
insides of the parts of the side surfaces 40, 41 may likewise be provided with friction-increasing
means 39.
[0034] Another variant of a package according to the invention is shown in Fig. 7. In this
variant, the wrapper 1 is provided with a second tear strip 42, provided parallel
to the wrapping direction. Thus, the tubular package is divisible into, for instance,
two equal parts I and II, as shown in Fig. 8. These parts I and II further correspond
to, for instance, a design as shown in Figs. 1 and 2.
[0035] On opposite sides of the tearing means 42 provided substantially parallel to the
wrapping direction, the inside of the wrapper is provided with friction-increasing
means 45 for the packages located adjacent the respective tear line. In the blank
47, as shown in Fig. 9, an opening 43 is provided in the tear strip 42 for engaging
the tear strip 42. An advantage of this embodiment is that the series of individual
packages can be supplied, for instance, as a large tubular wrapper, whereafter, for
instance, a part, after unpacking the individual packages, can be placed in a display
rack, while another part can be held in stock as a series.
[0036] In this description, friction-increasing means are to be understood to include at
least means that do not adhere to the individual packages to such an extent that the
latter can only be detached by pulling or tearing them loose, with the respective
individual packages thereby being damaged, but do increase the friction between the
wrapper and the individual packages. For that reason, preferably, types of adhesive
used to that end and as such must either have such low bonding properties that upon
detachment of the individual packages virtually residues of adhesive remain behind
on them, or, after being applied onto the wrapper, dry prior to placement of the individual
packages, such that at least substantially no bonding occurs anymore.
[0037] In a variant in which the first and last individual package of a series are secured
in the wrapper, thereby clamping intermediate packages, it is also possible to use
an adhesive that does adhere, preferably only in the corners and folding edges of
the wrapper, but in that case too the friction-increasing means mentioned earlier
are preferred.
[0038] The invention is not in any way limited to the exemplary embodiments described in
the drawings. Many variations thereof are possible within the scope of the invention
as outlined by the claims. Thus, for instance, a tear lip 36 can be provided in a
different place than the top surface, for instance in a side surface or along a rib
of the wrapper 6. Also, only one perforation line may be provided for tearing the
wrapper open. In the drawing the wrapper 6 is shown with closed side, top and bottom
surfaces. It will be clear, however, that openings may be provided in these surfaces
as well, for instance such that large parts of the sides of the individual packages
are visible through them. In the embodiment shown, identically-shaped, block-shaped
product packages are shown, arranged in one row. Naturally, more rows of individual
product packages can be accommodated next to and/or above each other in a package
in a comparable manner, while the individual packages can be designed differently
and/or be arranged differently in a series. Thus, for instance, the product packages
received between the first and last product package in a row can be arranged transversely,
as long as abutment against the inside of the wrapper, against each of the surfaces
thereof, is obtained. The series of individual packages, when packaged in the divisible
tubular wrapper, is preferably subdivided into subseries of individual packages, with
each subseries, for instance, separately enveloped with a transparent plastic film
or wrapped loosely. A blank for use in a package according to the present invention
can naturally be formed differently. Thus, for instance, the glue flap can be provided
at different positions or a different means may be provided for closing the wrapper
around the product packages, for instance insertion means, clamping means, elastic
means and the like. Instead of perforation lines, differently designed weakening lines,
such as tear lines, breaking lines or different perforation lines can be used. For
instance, on opposite sides of the wrapper incisions can be provided, slightly staggered
with respect to each other, which incisions do not reach through the entire thickness
of the blank, such that upon tearing the tear strip loose, the material between the
respective incisions will come loose. Thus a particularly straight tearing line is
obtained. Also, the perforation lines can be of a different design than a straight
design, for instance wavy, curved or the like. These versions fall within the scope
of the invention as laid down in the appended claims.
