A COLLAPSIBLE POUCH PROVIDED WITH A CLOSURE ASSEMBLY
The present invention relates to a collapsible pouch provided with a pre-assembled closure assembly, to a pre-assembled closure assembly to be sealed between two film walls of a collapsible pouch.
The present invention also relates to a method of manufacturing a collapsible pouch provided with a pre-assembled closure assembly.
The present invention also relates to a method of sterilization in a retort process of a product filled collapsible pouch provided with a pre-assembled closure assembly.
EP 763 482 B1 - upon which then preamble of claim 1 is based - discloses, e.g. with reference to figure 17 thereof, a collapsible pouch having a product chamber between two walls of film material including at least an inner layer of plastic. A closure assembly is sealed between the two walls of the collapsible pouch. This known closure assembly comprises a monolithic spout base and cap part, which is injection molded of plastic material. Herein the spout base and cap part comprises a spout base delimiting a bore which extends through the spout base. The bore has a lower opening at one end thereof and an opposed cap side opening. The spout base has a sealing wall having an exterior surface to which the two walls of the collapsible pouch are sealed with their inner layer of plastic. The spout base and cap part further comprises a cap which comprises a top wall and a downward depending skirt forming an interior side of the cap and delimiting a cap cavity which is aligned with the bore of the spout body. The skirt has a lower edge remote from the top wall. The cap is provided on the exterior side thereof with a circular rib forming a sealing face.
The cap is at the lower edge of the skirt integral with the spout base via an integrally molded frangible zone that connects the cap to the spout base such that the cap is manually removable and upon motion of the cap in an opening direction by the user for the first time the frangible zone breaks.
The present invention aims to provide an improved collapsible pouch with closure assembly, or at least to provide an alternative for known collapsible pouches with closure assemblies.
The present invention provides a collapsible pouch provided with a closure assembly according to the preamble of claim 1, which is characterized in that the closure assembly is a pre-assembled closure assembly and in addition to the monolithic spout base and cap part comprises a tubular inner part, preferably injection molded of plastic material, wherein the inner part comprises a fixation portion and a neck portion, which inner part has been inserted into the spout base and cap part via the lower opening of the bore thereof in a pre-assembly operation prior to sealing of the pre-assembled closure assembly between said two walls of the collapsible pouch, wherein the fixation portion is received and fixed in the bore of the spout base and wherein the neck portion protrudes from the spout base into the cap cavity and extends to a mouth of the neck portion, and in that the neck portion is provided with at least one circumferential sealing surface, and in that the cap has at the interior side thereof at least one circumferential sealing surface that sealingly engages said at least one circumferential sealing surface of the neck portion.
In embodiments the pre-assembled closure assembly allows to guarantee that when the cap is removed a clean neck portion appears, which is e.g. advantageous if it is envisaged that the consumer will drink directly from the pouch by placing the neck portion between the lips.
After removal of the cap any remnants of the broken frangible zone do not affect the outflow of product from the pouch. Also, e.g. when the consumer will drink directly from the pouch by placing the neck portion between the lips, any remnants will not be unpleasing to the consumer as in embodiments the design may place them remote from the pat where the consumers lips will touch the neck portion.
In embodiments the pre-assembled closure assembly allows for improved and/or alternative sealing arrangements of the cap in view of replacement of the cap after the first time opening compared to the mentioned prior art. For example, as will be explained also with reference to embodiments, multiple seals can be obtained between the cap and the neck portion at distinct locations.
In embodiments the pre-assembled closure assembly allows for the provision of ramps, screw thread, and the like that may aid the consumer in the removal of the cap as such means may cause the cap to be lifted whilst the consumer rotates the cap in order to remove the cap.
In embodiments the neck portion is circular in cross-section at it mouth end and is oval in cross-section in a region directly above the spout base. The cap then has a corresponding design, so that the frangible zone is an oval. This oval shape of the frangible zone is deemed favorable for the effort needed to cause the breaking of the frangible zone.
In embodiments the pre-assembled closure assembly allows for the use of different materials, e.g. plastics, for the spout base and cap part on the one hand and the inner part on the other hand.
For example the different materials have a different hardness.
For example the spout base and cap part plastic material is tailored for sealing to the inner layer of the pouch walls, e.g. of similar plastic material, and the inner part is tailored in view of mouth feel for the consumer.
For example the inner part has a different color than the spout base and cap part.
For example the spout base and cap part plastic material is polypropylene. This is e.g. advantageous when the pouch is subjected to a retort processing at elevated temperatures.
In an alternative the spout base and cap part is made of polyethylene.
For example the inner part is made of polypropylene. This is e.g. advantageous when the pouch is subjected to a retort processing at elevated temperatures. In an alternative the inner part is made of polyethylene.
In an embodiment the cap further includes an integrally molded annular inner sealing ring depending downward from the top wall, concentric with respect to the skirt of the cap, with the inner sealing ring having an inner face, an outer face, and a lower edge. The outer face of the inner sealing ring includes a first circumferential sealing surface that is - in the preassembled state - in sealing contact with a corresponding first circumferential sealing surface of the interior side of the neck portion and provides a first seal between the cap and the neck portion. This provides for an effective seal of the cap upon reclosing the pouch with the cap. Also it allows to sterilize the pre-assembled closure assembly internally, e.g. using hydrogen peroxide, without the sterilant entering between the cap and the neck portion.
It is noted that first seal, second seal, and third seal mentioned herein do not necessarily imply a total number of seals. Instead “first”, “second”, and “third” when discussing the seals are used in this application merely to distinguish between the mentioned seals. The preassembled closure assembly may comprise any of the mentioned seals, or multiple thereof.
In an embodiment the interior side of the neck portion is provided with an inward tapering annular guide surface that extends from said mouth opening downward and that is contacted by the inner sealing ring of the cap in the process of insertion of the inner part into bore and the cap cavity of the spout base and cap part, and then causes an elastic deformation of the inner sealing ring and/or the neck portion.
In an embodiment the exterior side of the neck portion at or near the mouth opening thereof forms a second circumferential sealing surface that is in sealing contact with a corresponding second circumferential sealing surface on the interior side of the cap to provide a second seal between the cap and the neck portion. For example this embodiment is combined with the first seal mentioned above, so that a double seal is obtained between the cap and the mouth end of the neck portion.
In an embodiment the interior side of the skirt of the cap - at or near the lower end of the skirt - is provided with a third circumferential sealing surface that is in sealing contact with a corresponding third circumferential sealing surface on the exterior side of the neck portion to provide a third seal between the cap and the neck portion, preferably said sealing surfaces being oriented to provide a radial sealing between the skirt of the cap and the neck portion. This seal is advantageous if the frangible zone is not embodied as a continuous, non-apertured circumferential body portion of the spout base and cap. The third seal then prevents any ingress of matter, e.g. sterilant, between the cap and the interior side of the skirt via openings in the frangible zone, e.g. between web portions forming the frangible zone with openings between adjacent web portions.
As is preferred the the frangible zone is a continuous, non-apertured circumferential body portion of the spout base and cap part. As explained this may obviate the desirability of a third seal as above.
In an embodiment the fixation portion of the inner part, preferably at or near the lower end thereof that faces away from the neck portion, is provided with a circumferential sealing surface that is in sealing contact with a corresponding sealing surface on the interior side of the bore in the spout base to provide a seal between the inner part and the fixation portion of the spout base. This design avoids any ingress of matter, e.g. product, between the inner part and the spout base from the interior of the pouch.
In an embodiment the spout base and the fixation portion are provided with cooperating abutment faces that define the position of the inner part relative to the spout base and cap part in the direction of insertion of the inner part. This e.g. allows to simply press the inner part into the spout base until the abutment faces meet and inhibit further insertion.
In an embodiment the spout base and the fixation portion are provided with cooperating antirotation faces that prohibit rotation of the inner part relative to the spout base and cap part. This e.g. is advantageous in view of any possible sealing between the inner part and the spout base and/or in view of the provision of any ramps or the like on the inner part that cooperate with the cap so as to lift the cap in the opening process. It is then preferred that the inner part is not rotatable relative to the spout base part.
In an embodiment that allows for easy securing of the cap upon reclosing of the pouch the interior side of the skirt and the exterior side of the neck portion are provided with cooperating snap-fit formations that allow to snap-fit the cap on the neck portion, preferably said snap-fit formations being engaged upon insertion of the inner part into the spout base and cap part.
In a practical embodiment the bore of the spout base is circular, e.g. formed by a cylindrical sealing wall extending around the circular bore. In another embodiment, which prevents rotation of the inner part relative to the spout base, the bore is non-circular, e.g. oval, hexagonal, etc.
In a practical embodiment sealing wall, e.g. a cylindrical sealing wall, is provided with two diametrically opposed fins thereon which extend in a common plane, the fins being sealed between the opposed film walls of the pouch as is known in the art.
In a practical embodiment the sealing wall has on its exterior multiple parallel ribs above one another as is known in the art.
In an embodiment the inner part is provided with an outward shoulder portion that extends underneath the lower edge of the skirt. This outward shoulder portion and the lower end of the skirt are provided with cooperating ramp faces that are inclined relative to a plane normal to the insertion direction of the inner part, such that upon rotation of the cap the cooperating ramp faces cause a lifting of the cap relative to the spout base. This lifting action may be used to enhance the breaking of the frangible zone and may assists the release of cooperating snap-fit formations between the cap and the neck portion when present.
In an embodiment the spout body is provided with a radially protruding flange above the sealing wall, e.g. so as to extend over the top rim of the walls of the pouch. The flange may be used for handling the pouch.
In an embodiment the spout body and cap part is injection molded from polypropylene and the inner layer of the film walls is of polypropylene. This is advantageous of sterilization by means of a retort process is envisaged of a product filled pouch. Polypropylene offers desirable characteristics for such applications.
In an embodiment the film walls include - in addition to the plastic inner layer - one or more layers chosen from: aluminum, polyamide, polyester.
In an embodiment the closure assembly and the pouch are resistant to a retort process wherein a product filled pouch is subjected to a temperature of between 115 and 125 Celsius for at least one minute, e.g. between one and 5 minutes.
In an embodiment the neck portion and the interior of the skirt are each provided with integrally molded and cooperating rotational connection means, preferably first and second screw threads on said neck portion and skirt respectively.
The present invention also relates to the pre-assembled closure assembly as disclosed herein, adapted to be sealed between opposed film walls of a collapsible pouch.
The present invention also relates to a method for manufacturing a collapsible pouch with a pouch closure assembly, e.g. of a product filled pouch with such a closure assembly. This method comprising the steps of: - providing a collapsible pouch comprising two film walls, said two film walls forming an opening between the two film walls, preferably between peripheral edge zones of the two film walls, - providing a pre-assembled closure assembly that is to be sealed in the opening between said two walls of the collapsible pouch, said providing comprising the steps of: - injection molding a spout base and cap part according to one or more of the preceding claims, - providing, e.g. injection molding, an inner part according to one or more of the preceding claims, - inserting the inner part into the spout base and cap part according to one or more of the preceding claims, so as to assemble the - sealing the pre-assembled closure assembly in the opening between said two walls of the collapsible pouch.
In an embodiment the method further includes the step of filling the pouch with a product, e.g. a liquid, powdery or pasty product.
Preferably the pouch is provided in a state with a single opening at the top, wherein prior to arranging of the pre-assembled closure assembly in this opening the pouch is filled with a product, e.g. a food product, wherein after the step of filling the pouch, the closure assembly is arranged in the opening and the sealing of the closure assembly therein is performed in one or more sealing steps.
In an embodiment the method further includes the step of sterilization of the product filled pouch in a retort process, wherein the product filled pouch is subjected to a temperature of between 115 and 125 Celsius for at least one minute, e.g. between one and 5 minutes, preferably at an elevated pressure, in an autoclave.
The present invention is advantageous for relatively small closure assemblies, e.g. with a diameter of the product passage between 4 and 15 millimeters.
The invention does not require additional tamper-evident elements on the spout and the cap to bring about a tamper-evident function, as the breaking of the zone already provides this function.
For example if an apertured frangible zone is envisaged the one or more apertures could be established not during the injection moulding process thereof, but by an additional manufacturing step. For example one or more holes or slits, or other weakenings, e.g. grooves, could be made in the moulded part to create or enhance the frangible zone. This additional manufacturing step could even be performed after the inner part has been inserted into the spout base and cap part, or even after the closure assembly has been sealed between the opposed film 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.
The assembly can be embodied to cause breakage of the frangible zone on the basis of a very limited rotation of the cap from its closed position, e.g. at most half a turn, so that the user experiences a rather immediate breakage when he/she starts to open the closure.
The invention will now be explained in more detail with reference to the drawings. In the drawings: fig. 1 shows in side view, partly in cross-section a collapsible pouch provided with a preassembled closure assembly, fig. 2a shows a preferred embodiment of a pre-assembled closure assembly in perspective view from above, fig. 2b shows the embodiment of figure 2a from above, fig. 3a shows the monolithic spout base and cap part of the assembly of figure 2a in perspective view from below, prior to insertion of the inner part of the assembly, fig. 3b, c shows the monolithic spout base and cap part of the assembly of figure 2a in part cross-sections, fig. 4 shows the pre-assembly of figure 1 in perspective view from below, with the inserted inner part, fig. 5 illustrates the removal of the cap to expose the neck portion, e.g. to be placed between the lips of a consumer drinking from a pouch to which the assembly is sealed, fig. 6a-c shows the assembly of figure 2 in part cross-sections, before removal of the cap, and a detail thereof on enlarged scale, fig. 7 shows the inner part of the assembly of figure 2a in perspective view from above, fig. 8 shows the inner part of figure 7 in perspective view from below, fig. 9a, b show the inner part of figure 7 in part cross-sections, fig. 10 shows the inner part of figure 7 from below, fig. 11 shows a second preferred embodiment of a pre-assembled closure assembly in perspective view from above, fig. 12 shows the embodiment of figure 11 from above, figs. 13a-c show the assembly of figure 11 in part cross-sections, before removal of the cap, and a detail thereof on enlarged scale.
With reference to figure 1 now a first embodiment of the invention will be discussed. As will be apparent for the skilled person, many features discussed with reference to the figure 1 embodiment equally apply, or may apply, to the embodiment shown in figures 2-10, and the embodiment shown in figures 11-13.
Figure 1 shows a portion of a collapsible pouch 1 having a product chamber 2 between two walls 3, 4 of film material including at least one inner layer of plastic. In this example the inner layer can be of polypropylene, e.g. combined with one or more additional layers in the film material as a laminated film material. For example the laminated film includes one or more layers chosen from: aluminum, polyamide, polyester.
Whilst not shown for reasons of clarity, it is understood that the pouch 1 has already being filled with a product, e.g. a food product.
After filling the product into the pouch 1 a pre-assembled closure assembly 10 has been sealed between the peripheral edge regions of the two opposed walls 3, 4 of the collapsible pouch 1.
The closure assembly 10 comprises a monolithic spout base and cap part 11, which is injection molded as a single unitary part of plastic material, e.g. of polypropylene.
This spout base and cap part 11 comprising a spout base 12 delimiting a bore 13 which extends through the spout base. This bore 13 has a lower opening at one end thereof and an opposed cap side opening (here shown at the top end of the base 12). The bore 13 of the spout base is circular, but may have another e.g. oval, hexagonal, or other form in cross-section, e.g. a form as so to act as anti-rotation fitting for inner part 30.
The spout base 12 has a sealing wall 14 has an exterior surface to which the two walls 3, 4 of the collapsible pouch 1 are sealed with their inner layer of plastic. It is shown here, by way of example, that the sealing wall 14 is a cylindrical wall, provided with two diametrically opposed fins 14a, b thereon which extend in a common plane. Also the sealing wall 14 here includes horizontal ribs 14c as part of the exterior of the sealing wall 14.
The spout base 12 is provided with an integrally molded and radially protruding flange 15 above the sealing wall 14.
The spout base and cap part 11 further comprises a cap 20, here a rotational cap to be opened by a rotational opening motion of the consumer.
The cap 20 has a top wall 2land a downward depending skirt 22 forming an interior side of the cap and delimiting a cap cavity which is aligned with the bore 13 of the spout body 12.
The skirt 22 has a lower edge 22a remote from the top wall 21.
The cap has protruding finger grip portions, here embodied as diametrically opposed wings 24, that facilitate exerting a torque by hand on the cap 20 in order to break the cap 20 from the spout base 12.
At the lower edge of the skirt 22 the cap 20 is integral with the spout base 12 via an integrally molded frangible zone 25 connecting the cap 20 to the spout base 12 such that the cap is manually removable and upon motion of the cap in an opening direction by the user for the first time the frangible zone breaks. As is preferred this frangible zone 25 is integrally molded as a continuous, non-apertured circumferential body portion of the spout base and cap part 11.
In addition to the monolithic spout base and cap part 11 the pre-assembled closure assembly comprises a tubular inner part 30, also injection molded of plastic material, as is preferred as a monolithic part.
This tubular inner part 30 comprises a fixation portion 31 and a neck portion 32. A product passage 33 forms the hollow interior of the tubular part. As is preferred the passage 33 is open at the lower end thereof and at a mouth opening 34 of the neck portion. In alternative embodiment a membrane or the like may extend across the passage 33, e.g. a pierceable or removable membrane. Possibly the membrane is integrally molded with the inner part 30, or for example, an aluminum foil membrane has been fitted over the mouth end 34 to be later removed by the consumer after first having removed the cap 20.
The inner part 30 has been inserted into the spout base and cap part 11 via the lower opening of the bore 13 thereof in a pre-assembly operation prior to sealing of the preassembled closure assembly between the two walls of the collapsible pouch 1.
The fixation portion 31 is received and fixed in the bore 13 of the spout base 12. The neck portion 32 protrudes from the spout base 12 into the cap cavity of the cap 20 and extends to the mouth opening 34 of the neck portion.
As can be seen the cap further includes an integrally molded annular inner sealing ring 23 depending downward from the top wall 21, concentric with respect to the skirt 22. This inner sealing ring 23 has an inner face, an outer face, and a lower edge.
It is illustrated that the outer face of the inner sealing ring 23 includes a first circumferential sealing surface 23a, near the edge, that is - in pre-assembled state - in sealing contact with a corresponding first circumferential sealing surface 32a of the interior side of the neck portion 32 to provide a first seal between the cap 20 and the neck portion 32.
It is illustrated that the interior side of the neck portion is provided with an inward tapering annular guide surface that extends from the mouth opening 34 downward and that is contacted by the inner sealing ring 23 of the cap 20 in the process of insertion of the inner part 30 into bore 13 and the cap cavity of the spout base and cap part 11, and then causes an elastic deformation of the inner sealing ring 23 and/or the neck portion 32.
It is illustrated that the exterior side of the neck portion 32, here near the mouth opening 34 thereof, forms a second circumferential sealing surface 32b that is in sealing contact with a corresponding second circumferential sealing surface 22b on the interior side of the cap 20, here of the skirt 22, to provide a second seal between the cap 20 and the neck portion 32 in the pre-assembled state.
It is illustrate that the interior side of the skirt 22 of the cap 20, here near the lower end of the skirt, is provided with a third circumferential sealing surface 22c that is in sealing contact with a corresponding third circumferential sealing surface 32c on the exterior side of the neck portion 32 to provide a third seal between the cap 20 and the neck portion 32. These sealing surfaces are here shown as oriented to provide a radial sealing between the skirt 22 of the cap 20 and the neck portion 32.
It is illustrated that the fixation portion 31 of the inner part 30, here at the lower end thereof that faces away from the neck portion 32, is provided with a circumferential sealing surface 31a that is in sealing contact with a corresponding sealing surface 12a on the interior side of the bore 13 in the spout base 12 to provide a seal between the inner part and the fixation portion of the spout base.
The figure 1 illustrates that the spout base 12 and the fixation portion 31 are provided with cooperating abutment faces 12b, 31b that define the position of the inner part 30 relative to the spout base and cap part 11 in the direction of insertion of the inner part.
In this example it is illustrated that the inner part 30 is snap-fitted into the spout base 12 by means of one or more bosses or protrusions 36 on the exterior of the inner part 30 engaging into corresponding one or more recesses 18 of the spout base 12. These cooperating formations may also be designed to form cooperating anti-rotation faces that prohibit rotation of the inner part 30 relative to the spout base and cap part 12.
The manufacturing of the collapsible pouch 1 with a pouch closure assembly 10 is done by providing the collapsible pouch 1 with the two film walls 3, 4 in a state wherein the two film walls 3, 4 form an opening between the two film walls, here between peripheral edge zones of the two film walls 3, 4.
Also the pre-assembled closure assembly 10 that is to be sealed in the opening between the two walls 3, 4 of the collapsible pouch is provided by: - injection molding a spout base and cap part 11, - injection molding the inner part 30, - inserting the inner part 30 into the spout base and cap part 11 so as to assemble the assembly 10.
The opening between the two film walls, preferably is the only opening of the pouch to be filled with the product. Then it is envisaged that the product, e.g. a liquid, powdery or pasty product, is filled into the pouch via this opening, prior to arranging the assembly 10 onto the pouch so as to hermetically close the pouch 1.
The pre-assembled closure assembly 10 is then placed in the opening between the two walls of the collapsible pouch 1 and sealed, e.g. by heat-sealing with heated jaws or ultrasonic or otherwise, between the film walls 3,4.
For some products, e.g. food products, it is envisaged that the method further includes the step of sterilization of the filled pouch 1 in a retort process, wherein the pouch 1 is subjected to a temperature of between 115 and 125 Celsius for at least one minute, e.g. between one and 5 minutes, preferably at an elevated pressure, in an autoclave, e.g. using steam. The assembly 10 is not penetrated by the sterilizing steam or other sterilizing agent.
With reference to figures 2-11 now a first preferred embodiment of a pre-assembled closure assembly according to the invention will be discussed. Herein the same or similar elements are denoted with same reference numerals as used in figure 1 starting from 100. The skilled person will have no problem ascertaining all corresponding features from the figures. As far as features have already been explained no further discussion will be presented here and reference is made to the above.
As discussed the sealing between the cap 120 and the neck portion 132 may involve one or more of the mentioned first, second, and third seal. In this example the third seal, at or near the lower edge of the skirt, is absent. This is acceptable as the zone 125 is non-apertured so that any ingress of matter from the outside is prevented as long as the cap 120 is integral with the spout base 112.
The cap 120, as is preferred, does have the first and second seals at the neck portion, as has been discussed above.
A further feature of the assembly 100 is that interior side of the skirt 122 and the exterior side of the neck portion 132 are provided with cooperating snap-fit formations 122d, 132d that allow to snap-fit the cap 20 on the neck portion. These snap-fit formations 122d, 132d are already engaged upon insertion of the inner part 130 into the spout base and cap part 112.
Another feature of the assembly 100 is that the inner part 130 is provided with an outward shoulder portion 137 that extends underneath the lower edge 122c of the skirt 122.
This outward shoulder portion 137 and the lower edge 122c of the skirt 1may be provided with cooperating ramp faces respectively that are inclined relative to a plane normal to the insertion direction of the inner part, here normal to the central axis of tubular inner part 130, such that upon rotation of the cap by the consumer the cooperating ramp faces cause a lifting of the cap relative to the spout base, assisting the release of cooperating snap-fit formations as well as promoting the breaking of zone 125.
In an embodiment, as an alternative to a snap-fit of the cap 20, 120 one can envisage that the neck portion and the interior of the skirt are each provided with integrally molded and cooperating rotational connection means, preferably with first and second screw threads on said neck portion and skirt respectively. It is then advantageous for the inner part to be rotated during insertion thereof into the spout body and cap part, so as to engage the threads, e.g. until a snap-fit between the fixation portion and the spout base is reached.
The inner part could also be secured in the spout base by means of heat-sealing, application of adhesive, elastic hook members, a press fit, or otherwise.
In the embodiment of figures 2-11 the bore 113 of the spout base is oval in cross-section and the fixation portion is shaped to fit in the oval bore, so that rotation of the inner part relative to the spout base and cap part is prohibited.
In the embodiment of figures 2-11 the frangible zone 25 is a continuous, non-apertured circumferential body portion of the spout base and cap part. As long as the cap 120 has not been removed, no ingress of matter along this zone 125 is possible.
In order to facilitate the breaking of the zone 25 it is illustrated that in the region of the inner part 130 that is present just above the spout base 112, the cross-section of the neck portion 132 and of the mating part of the cap 120 is oval. This enhances the breaking of the zone 125 when the cap 120 is twisted by the user to open the collapsible pouch.
With reference to figures 11-13 now a second preferred embodiment of a pre-assembled closure assembly according to the invention will be discussed. Herein the same or similar elements are denoted with same reference numerals as used in figure 1 starting from 200.
As far as features have already been explained no further discussion will be presented here and reference is made to the above.
The figures 11 and 12 clearly illustrate that the frangible zone 225 is embodied as an apertured frangible zone, with apertures 225a between frangible webs 225b. The provision of webs and apertures may be used to dimension the effort required for opening of the closure and/or to provide enhanced visibility of the first breaking of the webs 225b.
As an apertured frangible zone 225 does allow for the ingress of matter, it is shown that the cap 220 has at its lower end of the skirt 222 a sealing surface 222c which sealingly engages on a sealing surface 232c on the neck portion 234 of the inner part. Thereby any ingress between the cap 220 and the neck portion 234 is effectively blocked.
