A COLLAPSIBLE POUCH CLOSURE ASSEMBLY
The present invention relates to a collapsible pouch closure assembly, a collapsible pouch provided with a closure assembly, and methods for the manufacturing of such closure assembly and pouch.
5 US 2010213213 discloses a collapsible pouch closure assembly with a spout and with a screw cap having at the lower edge of the skirt a tamper-evident ring that is composed of two segments. A first end portion of each segment is connected to the skirt via a non-frangible connector. The second end portion is connected via a single integrally moulded frangible rod portion to an adjacent first end portion of the other segment. The neck of the spout has for 10 each segment a rotation preventing boss that is engageable with a corresponding abutment face on the second end portion of the segment. Upon first time removal of the cap, the frangible rod portion breaks and evidences the removal of the cap.
The present invention aims to provide an improved collapsible pouch closure assembly, or at 15 least to provide an alternative for known closure assemblies.
The present invention aims to provide a collapsible pouch closure assembly, wherein the tamper-evident function is very reliable and its function well recognizable for the user.
20 The present invention achieves one or more of the above-mentioned objects by providing a collapsible pouch closure assembly according to the preamble of claim 1, which is characterized in that the cap is provided with at least one projection comprising at least one anchoring portion that is adapted to be sealed between peripheral edge zones of the two foil walls of the collapsible pouch, said projection being moulded of plastic material and 25 extending outward from said skirt such that said at least one anchoring portion is sealable between said peripheral edge zones of the two foil walls of the collapsible pouch at a location different than the location of the spout seal portion, and said projection comprising a frangible zone with one or more frangible bridges connecting the anchoring portion to the projection such that upon rotating the cap in opening direction by the user from its closed position for 30 the first time, the one or more frangible bridges break thereby evidencing the removal of the cap from the neck.
-2-
The present invention is advantageous for relatively small closure assemblies, e.g. with a diameter of the product passage between 4 and 15 millimeters, as the invention does not require intricate cooperating elements on the spout and the cap to bring about a tamper-evident function.
5
The invention is advantageous as it easily allows to embody the at least one projection comprising the at least one anchoring portion as an anti-choking feature of the cap, e.g. having dimensions such that the cap (when removed from the spout) with said at least one projection can not pass through a 3 centimeter inner diameter tube.
10
The invention is advantageous as it easily allows to embody the at least one projection comprising the at least one anchoring portion as a finger grip that allows the user to engage one or more of his fingers thereon at a greater radius than the diameter of the skirt of the cap. This allows the user to exert a greater torque for opening of the cap without increased 15 effort. It also allows to embody the one or more frangible bridges with a certain robustness, as the user can rather easily create the effort needed to break the one or more bridges.
In a practical embodiment the cap may be provided with two diametrically extending wings that form two projections of the cap, preferably said wings each being provided with a single 20 anchoring portion and one or more associated breakable bridges. Preferably each wing extends at least 10 millimeters outward from the skirt of the cap. Preferably the wings are moulded integrally with the cap.
In a practical embodiment the spout seal portion is - in horizontal cross-section - boat or eye 25 shaped as is known in the field of spouts for collapsible pouches. A circular shape of the spout seal portion is also practical.
The spout seal portion may be embodied as a solid and rigid portion having a central channel therein aligned with the passage in the neck of the spout, e.g. the solid portion having a boat 30 or eye shaped outer contour in horizontal cross-section.
In a practical embodiment the spout seal portion comprises two sealing walls, preferably easily flexing, that delimit a boat or eye shaped space between them, each sealing wall being at its upper edge integral with a common transverse wall of the spout seal portion and each 35 sealing wall having a free lower edge. In a practical embodiment the sealing walls have a thickness between 0.5 and 2.0 millimeters.
-3-
In a practical embodiment the sealing walls are symmetric with respect to an imaginary vertical central plane of the spout seal portion.
In a practical embodiment a fin extending in said plane is provided at each joint of the ends of the sealing walls.
5 In a practical embodiment the one or more anchoring portions are located in said vertical central plane when the cap is mounted on the neck in its closed position.
In a practical embodiment the one or more projections are moulded as a unitary, monolithic part with the cap.
10 In an alternative embodiment the one or more projections are moulded as a unitary, monolithic plastic auxiliary body that is manufactured separately from the cap with the top wall and the skirt. The auxiliary body can then be mounted on the cap, e.g. the auxiliary body having a central opening into or through which the cap fits. The auxiliary body could be mounted on the cap such that the auxiliary body is not rotated along with the cap, when the 15 user rotates the cap. It is however preferred for the auxiliary body to be connected to the cap in such a manner that the cap and auxiliary body rotate together, e.g. a form fit connection between the auxiliary body and the cap or a weld or an adhesive connection. For example the auxiliary body and cap can be connected by a snap fit arrangement, preferably a permanent snap fit In a possible embodiment the auxiliary body and cap have all the features 20 of claim 1 of EP 2 033 906.
In the inventive closure assembly an anchoring portion may be embodied as a tab, e.g. a tab having generally planar, possibly roughened or with one or more ribs, main faces. The anchoring portion can also be shaped differently, e.g. as a rod, a ring, etc.
25
In a preferred embodiment the closure assembly has two anchoring portions, one on each side of the spout, but other embodiment, e.g. with a single anchoring portion or with multiple anchoring portions at one side of the spout, are also possible.
30 It is preferred that an anchoring portion is connected to the rest of the projection via multiple frangible bridges, e.g. three bridges. It is preferred that said one or more bridges are formed during the injection moulding process.
The inventive closure assembly allows for a highly reliable functioning of the tamper-evident 35 feature, in particular with respect to the breakage of the bridges that provide the visible evidence of the earlier removal of the cap. The arrangement operates reliable even when the -4- plastic parts are rather flexible, which allows for a limited use of plastic material which is relevant for such mass-produced plastic caps.
The assembly can be embodied to cause breakage of said frangible bridges on the basis of a 5 very limited rotation of the cap from its closed position, so that the user experiences a rather immediate breakage when he starts to open the closure.
The cooperating rotational connection means between the neck and the cap can be embodied as screw threads as is preferred. In the alternative these means can be embodied 10 as a bayonet connection or a twist connection wherein the neck is provided with track formations and the cap with one or more bosses that cooperate with said track formations.
The cooperating rotational connection means between the neck and the cap can be embodied to allow for complete disengagement of the cap in less than one full revolution of 15 the cap with respect to the spout, e.g. between a half turn and a three-quarters turn of the cap.
Preferably and as known in the art one or more cooperating angular cap positioning members are present on the neck and on the skirt that allow to secure the cap on the neck at 20 relatively high speed, normally with automated equipment, wherein the finally obtained closed position of the cap on the neck is such that the one or more anchoring portions are in an imaginary central vertical plane through the spout sealing portion. The closure assembly is arranged with this plane parallel to the peripheral edge zones of the foil walls.
25 Further preferred details of the inventive closure assembly are disclosed in the subclaims and in the description with reference to the drawings.
The present invention also relates to a collapsible pouch provided with a collapsible pouch closure assembly according to claim 12.
30
The present invention also relates to a method according to claim 14, and to a method for manufacturing a closure assembly as described herein.
In an embodiment the frangible zone is established in the projection not during the injection 35 moulding process thereof, but by an additional manufacturing step. For example one or more holes or slits, or other weakenings, e.g. grooves, are made in the moulded projection to create the one or more frangible bridges. This additional manufacturing step could even be -5- performed after the cap is mounted on the neck of the spout, or even after the closure assembly has been sealed between the opposed edge zones of the foil walls, e.g. using a cutting device, e.g. a laser cutting device, or a punching device, or other suitable tool, e.g. arranged at a dedicated station in a FFS installation.

Fig. 2 shows the assembly of figure 1 in assembled condition, 10 Fig. 3 shows the assembly of figure 2 sealed into a collapsible pouch,
Fig. 4 shows in partly cut-away view a portion of the assembly of figures 1 and 2,
Fig. 5 shows in perspective view an alternative embodiment of a collapsible pouch closure assembly according to the invention.
15 With reference to figures 1 - 4 now an embodiment of the collapsible pouch closure assembly according to the invention will be discussed.
Reference numeral 1 denotes a spout with a unitary injection moulded plastic spout body forming a tubular neck 2 around a product passage 3 in the article. The neck 2 forms a 20 mouth at a top end of the product passage. The neck 2 has an exterior side.
The spout body also has a spout seal portion 5 that is adapted to be sealed between peripheral edge zones of two foil walls of a collapsible pouch 30.
25 The portion 5 here includes diametrically opposed fins 5a, 5b as is known in the art.
Reference numeral 20 denotes a rotational cap, preferably a screw cap, that is injection moulded of plastic material.
30 The cap 20 is adapted to be secured on the neck 2 of the spout 1 as is shown in figures 2 - 4. The cap 20 seals the product passage 3 in closed position of the cap on the neck. Here the cap 20 seals the product passage at the mouth at the top end of the product passage, but other designs, e.g. wherein sealing is at a distance below the mouth, are also possible.
35 The cap 20 is adapted to be manually rotated by a user from the closed position in an opening direction to allow for removal of the cap from the neck of the article by a user to open the product passage 3. The cap may be tethered to the spout if desired.
-6-
The cap 20 comprises a top wall 21 and a downward depending skirt 22. The skirt 22 has an interior side, an exterior side, and a lower edge remote from the top wall 21.
5 The exterior side of the neck 2 and the interior side of the skirt 22 have cooperating rotational connection means. In this example the neck is provided with track formations 23 which cooperate with one or more bosses (not shown) on the interior side of the skirt. Opening of the cap 20 requires about half a turn of the cap in this example. The rotational connection means can also be embodied as first and second screw threads on the neck and skirt 10 respectively or as a bayonet structure.
The cap 20 does not comprises a tamper-evident ring, neither is such a ring mounted about the neck 2 of the spout.
15 The cap 20 is provided with two diametrically extending wings 25 that here both serve as finger grips to enhance the exertion of torque on the cap by the user and as anti-choke feature of the cap 20.
As can be seen the wings 25 here extend - as is preferred - in a common plane and are 20 embodied generally as plate shaped wings. It is envisaged that a wing may be perforated by one or more openings, both to reduce the amount of plastic and to enhance the anti-choke function. Perforations may also be used to create an aesthetical effect.
As is preferred each wing 25 is provided with a single anchoring portion 26. Between the 25 anchoring portion 26 and the rest of the wing 25 a frangible zone is present having one or more, here three as is preferred, associated frangible bridges 27.
A frangible bridge can be embodied as a rod like bridge (as shown here), but other weak bridges, e.g. like a film hinge where the thickness of the projection is locally weakened, are 30 also possible.
Each anchoring portion 26 is adapted to be sealed between peripheral edge zones of the two foil walls of the collapsible pouch, preferably the same edge zones as between which the spout seal portion is sealed.
The wings 25 are moulded of plastic material and extend outward from said skirt such a distance that each anchoring portion 26 is sealable between said peripheral edge zones of 35 -7- the two foil walls of the collapsible pouch at a location different than the location of the spout seal portion.
The anchoring portions 26 are each firmly sealed between the edge zones of the two foil 5 walls, so that upon rotating the cap in opening direction by the user from its closed position for the first time, the one or more frangible bridges 27 break thereby evidencing the removal of the cap from the neck 2.
In an embodiment, as shown in this example, the anchoring portion extends upward from the 10 edges zones so as to be easily visible by the user. This enhances the warning function of the tamper-evident structure according to the invention.
The figure 3 shows a top portion of a collapsible pouch 30 with two foil walls 31,32. In this figure it is illustrated that the pouch 30 is provided in a state with a single opening at the top 15 of the pouch so that the pouch can be filled via said opening, e.g. with a liquid, powdery, or pasty substance, e.g. a food or beverage product, a chemical product, e.g. a detergent, etc.
Prior to the arranging of the closure assembly in said opening the pouch 30 is filled with a substance, e.g. at a filling station of a form-fill-seal (FFS) installation as is known in the art.
20
After the step of filling the pouch, e.g. at a closure assembly placement and sealing station of the FFS installation, the closure assembly 1,20 with the cap in its closed position is arranged in this opening. Then the sealing of the pouch opening and the spout therein is performed in one or more sealing steps, e.g. using heated sealing jaws that press the foil walls onto each 25 other, onto the spout sealing portion 5, and onto the anchoring portions 26.
As is preferred, the sealing of the edge zones of the foil walls 31 , 32 is performed such that foil walls are sealed directly onto one another in the region beneath and to the sides of each anchoring portion 26, so that effectively the portion 26 is shielded by said sealed together foil 30 walls from the interior of the pouch. This enhances the stable anchoring of the anchoring portion 26 in the pouch and avoids any risk of leakage along the anchoring portion 26.
As is preferred, in assembled state of the pouch, each anchoring portion 27 is spaced from the spout seal portion 5 so that the foil walls 31,32 are sealed directly onto one another in 35 between.
-8-
The embodiment of figures 1 - 4 also illustrates that the spout seal portion comprises two sealing walls 6, 7, that delimit a boat shaped space between them. Each sealing wall 6, 7 is at its upper edge integral with a common transverse wall 8 of the spout seal portion and each sealing wall has a free lower edge.
5
The sealing walls 6, 7 are symmetric with respect to an imaginary vertical central plane of the spout seal portion 5. Each fin 5a, 5b extends in said central plane and is provided at each joint of the ends of the sealing walls 6, 7.
10 The one or more anchoring portions 26 are located in said vertical central plane when the cap is mounted on the neck in its closed position.
The skilled person will appreciate that the closure assembly is provided with its cap in closed position on the spout prior to the arranging of the assembly in the opening and the 15 performance of one or more sealing steps (e.g. using heated sealing jaws).
Preferably the sealing of the spout and the one or more anchoring portions 26 is performed in a single sealing step, using a single pair of sealing jaws.
20 Figure 5 shows an alternative embodiment of the inventive collapsible pouch closure assembly. As many features clearly correspond to features discussed with reference to figures 1-4 they have been given the same reference numeral and they will not be discussed here again.
25 The assembly 40 comprises a spout 1 with spout seal portion 5 and fins 5a, 5b.
The cap 20 here is provided with an alternative for the wing type projections 25, here a generally annular projection 50 extending as a flange around the skirt of the cap 20.
30 The projection 50 is, as is preferred, provided with perforations, e.g. to enhance the antichoke property provided by the projection 50.
The projection 50 could be moulded as a unitary, monolithic plastic part with the cap 20.
35 In this example it is envisaged that the projection 50 is embodied as an auxiliary body that is manufactured separately from the cap 20 with the top wall and the skirt.
-9-
The auxiliary body can then be mounted on the cap 20, here the auxiliary body 50 having a central opening into or through which the cap fits. The auxiliary body could be mounted on the cap such that the auxiliary body is not rotated along with the cap, when the user rotates the cap. It is however preferred, as shown here, for the auxiliary body to be connected to the 5 cap in such a manner that the cap and auxiliary body rotate together, e.g. a form fit connection between the auxiliary body and the cap or a weld or an adhesive connection. For example the auxiliary body 50 and cap 20 can be connected by a snap fit arrangement, preferably a permanent snap fit In a possible embodiment the auxiliary body and cap have all the features of claim 1 of EP 2 033 906.
10
The auxiliary body is provided with one or more, here a single, anchoring portion 26. Here, as is preferred, said anchoring portion lying in the same central vertical plane as the fins 5a, b.
15 As explained with reference to figures 1 -4 one or more frangible bridges 27 are provided. When the spout 1 with its spout seal portion 5 and the anchoring portion 26 have been sealed between opposed edge zones of two foil walls of the pouch, and it is attempted to unscrew the cap, the bridges 27 break thus evidencing the opening of the closure assembly.
