[0001] This application claims priority to and is a U.S. National
Phase filing of PCT International Application Number
PCT/EP2006/002475, filed on Mar. 17, 2006, which claims priority
under 35 U.S.C. .sctn. 119 to German Patent Application Number 10
2005 016 268.1, filed on Apr. 8, 2005. The disclosures of the
above-described applications are hereby expressly incorporated by
reference in their entireties.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The invention relates to a tubular pouch in accordance with
the preamble of patent claim 1.
[0004] 2. Description of the Related Art
[0005] Tubular pouches of the kind in question herein are generally
known and are used for conserving, storing and transporting liquid,
paste-form and solid contents as well as for bringing such contents
into commercial availability; such tubular pouches and packagings
produced therefrom have proved to be extremely advantageous inter
alia on account of their being lightweight and easily shapeable and
printable. A further advantage of such tubular pouches is their
ease of disposal.
[0006] The opening behaviour of such tubular pouches or tubular
pouch packagings has proved to be problematic, however. Such
packagings are usually opened by tearing open the packaging, it
being usual to provide a notch in a lateral sealing seam by means
of which further tearing of a foil forming the tubular pouch,
generally of two side wall foils, is initiated.
[0007] A further possible way of opening such a tubular pouch
packaging is to pull apart two side faces forming the tubular pouch
in the region of a seal, the seal breaking open.
[0008] Those two variants of opening have the serious
disadvantages, however, that when the packaging is torn into or
torn open, the foil forming the tubular pouch tears in an
undirected and uncontrolled way, so that the contents of the
packaging are spilled, resulting in loss of the packaged goods.
[0009] Furthermore, after such tearing-open, the interior of the
tubular pouch is often poorly accessible, because torn or residual
portions of the packaging make it difficult to gain access to the
interior of the tubular pouch, for example with the hand or a
spoon. Intentionally pouring out the contents of the packaging is
also often impeded by residual portions of the packaging, so that
the contents of the packaging on the one hand also come into
contact with outer parts of the packaging, with the result that on
the one hand the contents of the tubular pouch can be contaminated
on being poured out and on the other hand can be dispensed only in
an uncontrolled way.
[0010] Finally, a further variant of opening comprises the use of a
pair of scissors by means of which an upper portion of the closed
tubular pouch is cut off and removed, so that the interior volume
of the tubular pouch is then freely accessible. Although that
variant enables a tubular pouch portion that closes the tubular
pouch to be cleanly separated, it creates the problem firstly that
it is necessary always to have a pair of scissors to hand and
secondly, if the scissors used are not clean, that there is a risk
that both the cut edges and the contents of the tubular pouch will
be contaminated, with the result that the contents may become
unusable.
[0011] The problem underlying the invention is to provide a tubular
pouch of the kind mentioned at the beginning which can be opened
hygienically, simply and without aids, so that the interior of the
tubular pouch is accessible without problems.
[0012] That problem is solved by a tubular pouch according to
patent claim 1.
[0013] The problem is solved, in particular, by a tubular pouch
having a tubular pouch body and a lid piece and, optionally, a
base, especially a standing base or stand-up base, the lid piece
being fixed on the tubular pouch by means of a cuff.
[0014] In accordance with one embodiment of the invention, the cuff
is formed integrally with the lid piece, the cuff extending around
the periphery of the lid piece and at least over an end portion of
the tubular pouch body at the lid-piece end thereof.
[0015] In accordance with an alternative embodiment of the
invention, the lid piece co-operates with the cuff so that the cuff
at least partially overlaps, especially engages over, the lid
piece, and the cuff extends around the periphery of the lid piece
and at least over a portion of the tubular pouch body at the
lid-piece end thereof. In that case, the cuff is produced as a
separate component. The cuff extends both over the periphery of the
lid piece and over the periphery of the end portion of the tubular
pouch body at the lid-piece end thereof and thereby holds the lid
piece fixed in its position on the tubular pouch body.
[0016] In the latter case, the construction of the cuff is like
that of an angle profile, so that one limb of the cuff extends over
the peripheral edge of the lid piece and the other limb extends
over the peripheral edge of the tubular pouch body at the lid-piece
end thereof.
[0017] According to the invention, at least one portion of the cuff
that extends over the edge portion of the tubular pouch body at the
lid-piece end thereof is sealed or adhesively bonded thereto.
[0018] The cuff according to the invention accordingly fulfils two
functions: the first is to fix the lid piece on the tubular pouch,
the lid piece either resting loosely on the tubular pouch body and
being held in place by means of the cuff which in turn is sealed to
the tubular pouch body.
[0019] The second function of the cuff is to ensure that it is
impossible to open the lid piece without removing the cuff.
Accordingly, the cuff constitutes a safety measure by means of
which improper opening of, for example, a reclosable lid piece is
effectively prevented (closure integrity). That is expedient, for
example, when the lid piece itself, with a cold-seal adhesive that
is suitable for reclosure, is used for closing the tubular
pouch.
[0020] The cuff itself has at least one, preferably two
co-operating grip region(s) in the form of opening tabs.
Accordingly, for opening the cuff the grip region(s) is/are grasped
and separated from the tubular pouch body by pulling, so that the
seal between the tubular pouch body and the portion of the cuff in
contact therewith is broken.
[0021] Preferably, for attachment of the cuff there is used a
sealing medium which effectively prevents reclosure of the cuff, so
that there is no doubt as to whether a cuff has been opened.
Optionally, the cuff can also be constructed so that after being
opened it has broken sites or torn sites.
[0022] In accordance with a further embodiment, the lid piece is
placed over the associated peripheral edge of the tubular pouch
body, so that the tubular pouch body is surrounded at least on the
outside by the edge of the lid piece. In that case, the internal
diameter of the edge of the lid piece is slightly larger than the
external diameter of the tubular pouch body, so that the lid piece
can simply be placed onto the tubular pouch body.
[0023] Alternatively, the lid can be trough-shaped or dish-shaped
and have a diameter that enables the lid piece to be inserted into
the tubular pouch body. In that embodiment, the lid piece
preferably has its edge turned over towards the outside so that in
this variant the peripheral edge of the tubular pouch body at the
lid-piece end thereof is surrounded by the edge of the lid piece
both on the inside and on the outside. Such a lid piece is suitable
in an extremely advantageous way for reclosure of the tubular
pouch; the lid piece, by virtue of its surrounding the tubular
pouch body on the inside and the outside, rests so firmly against
the tubular pouch body that there is no risk of its unintentionally
falling off the tubular pouch body. Instead, in this embodiment the
lid piece can easily be removed from the tubular pouch body by
hand; unless removed manually, however, the lid piece keeps the
tubular pouch securely closed.
[0024] In accordance with a further embodiment of the invention, a
desired tearing line is formed between the sealed or adhesively
bonded seam of the cuff and the lid piece. That variant according
to the invention is advantageous especially when the cuff is formed
integrally with the lid piece, and the cuff can be at least
partially separated from the lid piece in order to open the tubular
pouch.
[0025] In an advantageous embodiment, the cuff is formed by a foil
strip the end portions of which are joined, especially sealed or
adhesively bonded, so that they overlap one another, an outer end
portion serving as grip tab for opening the cuff (lap-seal
variant).
[0026] The overlapping of the end portions can therefore be in the
form of a lap seal or a fin seal. In the latter case, the cuff can
be opened by gripping the end portions of the foil strip and
pulling them apart, so that the fin seal breaks open and the cuff
can be removed, so that the lid piece of the tubular pouch can be
removed.
[0027] In an extremely advantageous development of the invention,
the lid piece is configured with an angled edge strip which in the
longitudinal direction of the tubular pouch can face either towards
or away from the latter. In the former case, the lid piece can
preferably be placed over the portion of the tubular pouch body
located at the lid-piece end thereof, while in the latter case, as
mentioned above, insertion of the lid piece, which is accordingly
of dish-like construction, into the tubular pouch comes into
consideration, the angled edge strip of the lid piece preferably
projecting above the rim of the peripheral edge of the tubular
pouch body.
[0028] In the two last-mentioned cases, according to the invention
the cuff is sealed or adhesively bonded to the outside of the edge
strip, so that the cuff remains on the lid piece when the lid piece
is removed from the tubular pouch body. For that purpose, a
strongly adhesive contact adhesive or a strong seal is preferably
chosen in order to prevent the cuff from falling off the lid
piece.
[0029] A further variant of a cuff according to the invention has
at least one grip tab extending in the longitudinal direction of
the pouch, especially towards the base of the pouch, by means of
which the cuff can be opened, or torn open. As mentioned above, the
grip tab is free of adhesive and/or sealing medium.
[0030] Otherwise, the tubular pouch body itself and, where
applicable, the lid piece and/or the base of the tubular pouch
is/are of relatively rigid construction. This is particularly
advantageous when the tubular pouch contains liquid or paste-form
contents. When the contents are solid, they can themselves impart a
certain stability to the tubular pouch body.
[0031] A considerable advantage of a tubular pouch according to the
invention is that substantially the entire cross-sectional opening
of the tubular pouch body can be opened, so that optimum access can
be gained to the interior volume of the tubular pouch, including,
for example, with a spoon, a fork or some other removal aid.
[0032] In accordance with one embodiment, the tubular pouch body is
produced from a square or rectangular foil blank, the overlapping
edge regions being joined to one another by means of fin-seal
and/or lap-seal sealing to form a tubular body. Alternatively, the
tubular pouch body is produced as part of an extruded foil tube
which is preferably of seamless construction.
[0033] Furthermore, the tubular pouch body is preferably made from
a laminate, especially an aluminium laminate, having at least one
sealing layer and optionally at least one barrier layer. The
barrier layer preferably consists of SiO.sub.2, ethyl vinyl alcohol
(EVOH), an oriented polyolefin, preferably polypropylene (OPP), or
a metal foil, for example an aluminium foil.
[0034] Moreover, the lid piece and/or the base are made
substantially of the same materials as the tubular pouch body. As a
result, the tubular pouch can be produced very cost-effectively,
because both the lid piece and the base are made of the same foil
or the same laminate as the tubular pouch body itself. For that
purpose, it is possible to use either the foil forming the future
tubular pouch body, prior to formation of the tubular pouch body,
or a length of extruded tube, which are in each case detached for
forming the lid piece and the base. For example, it is possible for
such a short length of tube simply to be sealed on one side to form
the base and then incorporated into the tubular pouch body, with
the latter optionally being stretched, and joined sealingly
thereto, that is to say sealed or adhesively bonded thereto.
[0035] Both the lid piece and the base and/or the tubular pouch
body have a thickness in the range of from 50 .mu.m to 1000 .mu.m,
preferably from 100 .mu.m to 500 .mu.m, and especially from 150
.mu.m to 350 .mu.m. Adhering to those dimensions on the one hand
ensures that the tubular pouch is lightweight and has sufficient
durability and stability, including for carbonic-acid-containing
pouch contents. Furthermore, the lid piece, the base and the
tubular pouch body itself is sterilisable, so that foods, beverages
and stimulants can also be introduced into the tubular pouch and
packaged hygienically therein.
[0036] Further embodiments of the invention will be found in the
subsidiary claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0044] In the description which follows, parts that are the same or
have the same action have been given the same reference
numerals.
[0045] In accordance with one exemplary embodiment, the tubular
pouch 10 according to the invention has a tubular pouch body 12
which can be formed by means of lap-seal sealing. At its base end,
the tubular pouch body 12 can be provided with a deep-drawn
stand-up base and can be sealed tightly thereto peripherally around
the edge. The tubular pouch body 12 is approximately circular both
in its base region and in its lid-piece region 20. Other
cross-sectional shapes, such as oval, rectangular etc., are also
possible, however. The lid piece 14 of an approximately
circular-cylindrical tubular pouch body 12 consists of an
approximately circular part, especially a foil part, which has a
slightly greater diameter than the tubular pouch body 12. At the
edge, the lid piece 14 is placed over the tubular pouch body 12.
The lid piece 14 of the closed tubular pouch 10 is fixed on the
tubular pouch body 12 by having sealed to the tubular pouch body 12
a cuff 18 which by means of a limb extends over the lid piece 14 at
the top and is stretched peripherally both around the lid piece 14
and around the tubular pouch body 12. For tearing open the cuff 18,
the latter has on two sides a tab 22, for example in the form of a
fin seal 34, having two respective grip regions which extend away
from the tubular pouch body 12 substantially at a right angle and
which can each be grasped with two fingers of a hand. For opening,
the two ends of the tab 22 sealed with the fin seal 34 are pulled
and in that way the cuff 18 is removed from the tubular pouch body
12.
[0046] Further embodiments of the invention are shown
diagrammatically in FIGS. 1 to 6.
[0047] For example, FIG. 1 shows a tubular pouch 10 according to
the invention, consisting of a tubular pouch body 12, a base (not
shown) and a lid piece 14 which is fixed by means of a cuff 18 on
the upper, lid-piece-end peripheral edge 20 of the tubular pouch
body 12. The cuff 18 is firmly joined by means of a very strong
seal 36 to the outside of an edge strip 32 of the lid piece 14,
which edge strip is angled upwards in FIG. 1. The seal 36 extends
over the periphery of the lid-piece edge 32.
[0048] By means of an adhesively bonded seam 26, the cuff 18 is
joined to the outside of the peripheral edge 20 of the tubular
pouch body 12 at the lid-piece end thereof. That adhesive bond
likewise extends over the periphery of the tubular pouch body. For
opening the cuff 18, a grip region in the form of tab 22 is
provided. The adhesively bonded seam 26 is weaker than the seal 36
in terms of adhesive strength, which ensures that when the cuff 18
is being opened the cuff becomes detached only from the tubular
pouch body 12.
[0049] In accordance with the embodiment described above, the lid
piece 14 is of dish-like construction and extends into the tubular
pouch body 12 to the depth of about half its angled edge strip 32.
The portion of the angled edge strip 32 projecting out of the
tubular pouch body 12 is used for the join to the cuff 18.
[0050] FIG. 2 shows a diagrammatic view of a further embodiment
according to the invention which is a modification of the
embodiment according to FIG. 1. In accordance with this variant,
the cuff 18 is formed integrally with the lid piece 14. The lid
piece 14 is accordingly joined to the tubular pouch body 12 via the
sealed or adhesively bonded seam 26 of the cuff 18. For opening the
tubular pouch 10, it is accordingly necessary first to open the
cuff 18, it being possible to break the sealed or adhesively bonded
seam 26 between the cuff 18 and the tubular pouch body 12 by
pulling on the tab 22. For easier release of the lid piece 14, it
is also possible to provide a desired tearing line 28 along which
the cuff 18 can be separated from the lid piece 14. Such a desired
tearing line 28 is located between the adhesively bonded seam 26
and the upper edge of the lid piece or pouch.
[0051] FIG. 3 shows a diagrammatic view of a third embodiment of a
tubular pouch 10 according to the invention in which the lid piece
14 has a downwardly angled edge strip and is placed cap-like over
the peripheral edge 20 of the tubular pouch body 12 at the
lid-piece end thereof. The cuff is in that case in the form of an
annular angle profile, the horizontal limb of the cuff 18 extending
over the peripheral edge of the lid piece 14, while the vertical
limb, or the limb extending parallel to the longitudinal axis of
the pouch, is joined to the tubular pouch body 12 by means of the
sealed or adhesively bonded seam 26 and accordingly holds the lid
piece 14 on the tubular pouch body 12. For opening such a tubular
pouch variant, again the tab 22 can be grasped and the sealed or
adhesively bonded seam 26 broken by pulling, so that the cuff 18,
which is in the form of a separate component, can be removed. lid
piece 14 is accordingly free to be removed.
[0052] FIG. 4 shows a fourth embodiment of a tubular pouch
according to the invention in which the cuff 18 is again formed
integrally with the lid piece 14 and can be separated therefrom
along a desired tearing line 28. In accordance with the
part-sectional view of the embodiment according to FIG. 4, the tab
22 is used for opening the cuff 18. Here too, the desired tearing
line 28 is located between the sealed or adhesively bonded seam 26
and the upper edge of the pouch or lid piece.
[0053] FIGS. 5 and 6 show a diagrammatic cross-sectional view of a
lid-piece-end peripheral edge 20 of a tubular pouch body 12
according to the invention having an associated cuff 18. The cuffs
18 are in each case in the form of foil strips and have end
portions 30 that overlap one another. In the case of FIG. 5, those
end portions 30 are in the form of a fin seal 34 and in the case of
FIG. 6 in the form of a lap seal. For opening the tab, according to
FIG. 5 the grip regions 22 of the fin-seal seal are grasped and
pulled apart from one another so that the seal is broken and the
cuff 18 is accordingly opened.
[0054] In accordance with FIG. 6, a grip region 22 is provided on
the outer end portion 30 of the foil strip, by means of which the
cuff 18 can be broken open to open the lap-seal seal.
[0055] The packagings described above are excellently suitable for
storing solid items, it being emphasised that a seal or some other
sealing means can likewise be provided between the lid piece and
the limb of the cuff that engages over the lid piece. In that case
the storage of paste-form and liquid tubular pouch contents is also
possible if the cuff is not anyway firmly joined to the lid
piece.
[0056] It should be pointed out here that all the above-described
parts, considered alone and in any combination, especially the
details shown in the drawings, are claimed as being important to
the invention. Modifications thereof will be familiar to the person
skilled in the art.
