Description
CLOSURE CAP
FIELD OF THE INVENTION
The invention relates to closure caps for containers having a container opening, to containers with a closure cap, as well as to a process for the manufacture of closure caps.
BACKGROUND ART
Different constructions for closure caps for containers axe already known. For example, closure caps are known which cover container openings for the closure thereof and are moved away from the region of the container opening for the opening thereof. An example for such prior art are conventional screw-on caps, which often have a thread which for closing is meshed with a thread at the container opening, often on a container neck. It is normally provided in those constructions that the closure caps in the open condition of the container opening are completely separate from the container.
Such constructions are used, for example, for the packaging of hygiene articles, for example toothpaste, shower gels, shampoos or the like, or for the packaging of food, for example, ketchup or the like.
Closure caps are also known in which the closure cap itself has a further opening which can be opened or closed. Such closure caps are generally applied at the container opening, whereby the removal of stored medium from the container is most often made possible by the opening and closing of only the opening in the closure cap, while the closure cap remains on the container during the opening. This can be achieved, for example, with a hinged lid or a similar element. As mentioned, such closure caps are often removably mounted to the container so that, for example, a refilling of the container is easily achieved. Examples of this type of closure caps are also known in the field of food packaging or hygiene article packaging.
Sealing elements are also often used in known containers or combinations of a container and a closure cap. For example, conical seal arrangements or cylindrical seals axe used. It is further known to insert a separate insert into the container opening which insert is provided with an opening through which medium can be removed from the container. Those inserts are constructed to produce an essentially sealed connection between the insert and the container so that the medium can exit the container only through the opening in the insert. A closure cap, for example, is then screwed or pressed onto this insert by which the opening in the insert or the container can be opened and closed.
SUMMARY OF THE INVENTION
It is an object of the invention to provide a reliable closure cap which can be easily and economically manufactured, as well as an arrangement of a container and closure cap, and a process for the manufacture of a closure cap.
This object is achieved with a closure cap.
In accordance with the invention, the closure cap is constructed such that the container opening of a container can be opened by way of the closure cap for dispensing stored medium from the container and closed for substantially preventing dispensing of stored medium from the container. The closure cap can be constructed, for example, for the opening and closing of an opening provided in the container neck. In this context, "closing" and "opening" do not necessarily mean that the cross-section of the opening itself or of the container opening is changed. The closing and opening is rather to be understood as conditions in which medium can be dispensed or not dispensed from the container or the combination of container and closure.
The closure cap in accordance with the invention includes at least one circumferentially continuous wall portion. The latter extends especially about a longitudinal axis of the closure cap.
It is further provided in accordance with the invention that a strip seal arrangement with at least two lamellae is provided, which are spaced apart in axial direction of the closure cap and combined into one piece with the closure cap.
It can be further provided that the closure cap has a retaining portion for holding it on a container. Such a retaining portion can, for example, be part of a snap closure, or a thread. It can also be provided that the strip seal arrangement is a retaining arrangement or part of a retaining arrangement. The term "retaining arrangement" is to be understood especially to define a retaining arrangement - possibly in co-operation with a counter retaining arrangement - which provides that the closure cap - upon corresponding positioning - cannot be released from the container under the force of its own weight. It can also be provided that the retaining arrangement is constructed such that a certain minimum force is required for detachment from the container. The retaining arrangement can also be in the form of a surface which can be frictionally connected with a surface region of the container or a container neck.
Preferably, the closure cap includes a cap body as well as a hinged lid connected thereto. The closure can also be constructed as a screw-on closure.
Especially, the closure cap can also be a screw-on closure which - when screwed onto a container or container neck - clears a corresponding container opening when the screw connection is released. However, it can also be provided that an additional opening is provided in the closure cap which can be closed, for example, by a hinged lid, whereby this closure cap can be screwed onto a container neck or a container.
In a preferred embodiment, the closure cap has a hinged lid which is connected to the cap body by way of a film hinge. Other hinges can also be used.
Several or all lamellae of the strip seal arrangement can be of annular shape and continuous. Especially, they can have a washer type shape. Several or all lamellae of the strip seal arrangement can be of essentially the same shape. However, they can also have different shapes.
In a preferred embodiment, several or all lamellae of the strip seal arrangement are essentially positioned parallel to one another. However, they can also be arranged at an angle to one another. The strip seal arrangement preferably includes two lamellae.
However, the strip seal arrangement can also include three, four, five or more than five lamellae. The lamellae of the strip seal arrangement can be positioned on the same wall or the same wall portion. However, they can also be positioned on different wall portions which are positioned, for example, to be opposite one another. In a preferred embodiment, the lamellae of the strip seal arrangement extend essentially radially relative to the longitudinal axis of the closure cap.
It can also be provided that the closure cap has a cap body without an additional hinged lid. This is the case, for example, with a closure cap constructed as a screw-on closure which does not include a further dispensing opening separate from the container opening.
The cap body can be provided at its upper end with a cover plate. Such a cover plate can have a planar or non-planar shape and can be of constant or variable thickness.
Such a cover plate is especially an upper cover. However, it need not be, although this can also be the case, the uppermost cover of such a cap. For example, in a closure cap with hinged cap lid, an upper cover plate can be provided which has a dispensing opening and can be closed - in the closed condition - by a lid position above the cover plate.
The language "at its upper end" therefore does not necessarily mean that the cover plate must actually form the upper end, although this variant is also preferred.
In a preferred embodiment, a first wall is provided which is circumferentially continuous and extends about a longitudinal axis or central longitudinal axis of the closure cap, from which first wall several lamellae extend essentially radially. It can be provided that these lamellae extend radially inwardly from this wall, or radially outwardly. The first wall can be, for example, concentrical to the central axis. It can be provided that this wall extends up to an upper cover plate. In such a construction, it can be especially provided that the circumferentially closed first wall is completely circumferentially closed between these lamellae and the upper cover plate.
The first wall can have a cylindrical contour, for example. It can also have -especially viewed in longitudinal direction of the closure cap - differently oriented portions. Especially the first wall can be constructed such that it has a cylindrical contour as well as an adjacent portion reoriented by 180 degrees, which is then again followed by a cylindrical portion. Lamellae can be provided, for example, at this further cylindrical portion. Other constructions are also preferred. In a preferred construction, a first channel is provided which extends radially inwardly of the first wall in longitudinal direction of the closure cap and which is open at its lower end. The lower end is thereby especially that end which when the closure cap is positioned or mounted on the container is directed towards the container.
In a preferred embodiment, an upper cover plate is provided in the closure cap which has a dispensing opening that opens into the first channel.
It is further preferred that the closure cap has several radia,lly spaced walls. Such walls can be, for example, concentric to one another. Such walls can be respectively cylindrically shaped or have other shapes. It can also be provided that three walls of the closure cap are provided which extend essentially in longitudinal direction of the closure cap and are radially spaced from one another. Such walls can respectively extend about a central longitudinal axis of the closure cap. They can respectively enclose the same or different angles with such a central longitudinal axis. They can have a straight or curved shape or other shape in longitudinal direction of the closure cap. Especially preferred are two radially spaced walls of which one has essentially radially extending lamellae of the strip seal arrangement and which walls are spaced such that a container neck of a container can be received between the walls in such a way that the lamellae respectively engage the container neck over the whole circumference thereof.
It is fuxther preferred that the closure cap is provided with a thread or a thread portion by which the closure cap can be connected with a container, especially removably connected. Other connecting mechanisms which allow a releasable connection between the closure cap and the container are also preferred. It can be provided especially that the closure cap is provided with a snap closure or part of a snap closure. A
"complementary portion" of such a snap closure can be provided, for example, on the container or the container neck. In a preferred embodiment, two radially spaced walls of the closure cap are provided which extend essentially in longitudinal direction of the closure cap and define an intermediate space - as already described - in which the container neck of a container can be received. In such a construction, it is especially preferred that lamellae of the strip seal arrangement extend from one of these walls and in particular on that side which is facing the other one of these walls. According to an especially preferred embodiment, a thread or threaded portion is provided on the other of these walls.
Especially preferably the other one of these walls is the one located radially further outwardly.
A thread or threaded portion can also be provided on a wall of the closure cap extending in longitudinal direction of the closure cap, and lamellae of a strip seal arrangement can be provided on the same wall. This can be especially 'achieved in that the lamellae are positioned above the thread or threaded portion.
The thread can he an inner thread or an outer thread.
The closure cap as a whole is preferably formed in one piece.
The lamellae are preferably made of elastic material. Preferably, the lamellae are made of plastics material. Especially preferably, the whole closure cap consists of plastics material. It can be made of one plastics material or different plastics materials. It is preferably made ofplastics materials which are suitable for injection molding processes.
Especially preferably the closure cap andlor the lamellae are made of a thermoplastic elastomer (TPE), or of polypropylene (PP), or polyethylene (PE), or combinations of these plastics materials.
Preferably, the lamellae are respectively made of solid material; however they can also be hollow.
The closure cap is preferably a hinged lid closure or a screw-on closure.
The object is further achieved in accordance with the invention, in a container in particular for the storage of a medium. Such a medium can be liquid, for example. In an especially preferred embodiment, such a medium is viscous or highly viscous.
However, it can also be provided that such a medium is a pourable material.
Such a medium can be, in particular; a shower gel or a shampoo or ketchup or the like.
The container has a container opening which can be opened and closed by way of the closure cap.
This can be achieved in that the closure cap is positioned on the container -for example, removably positioned - and includes a further opening with a closure mechanism for this opening. This can be achieved, for example, in that the opening can be opened and closed by a lid pivotally hinged to the closure cap.
The closure cap is especially constructed as described in this disclosure. It can be provided that the container and the closure respectively have one - equally or differently constructed - retaining mechanism or retaining region, whereby these retaining regions or retaining mechanisms co-operate or can co-operate for the holding of the closure cap on the container.
The container especially preferably has a container neck. The latter can be constructed such that it projects from the container surface. A container neck can, however, also be constructed such that it extends from the outer surface of the container to the container interior.
The closure cap can be removably affixed to such a container neck or in the region of such a container neck.
In a preferred embodiment, it is provided that the lamellae of the strip seal arrangement of the closure cap engage the outer surface and/or the inner surface of the container neck of the container and in particular circumferentially continuously.
The object is further achieved with a process in accordance with the invention, providing for the manufacture of a one-piece closure cap. This closure cap can be, for example, a closure cap as described in different constructions within this disclosure.
According to the process of the invention, it is provided that the closure cap is manufactured in an injection molding process. It is thereby especially provided that initially a first portion of the closure cap is manufactured in a first step by way of the injection molding process and that a strip seal arrangement with at least two lamellae is subsequently overmolded onto this first portion. It can be provided that after the overmolding of the lamellae, further parts of the closure cap are overmolded onto the cap.
It can also be provided that the overmolding of the lamellae is carried out when all remaining parts of the one-piece closure cap were also manufactured in the injection molding process. It can also be provided that a part of the closure cap is manufactured in a different process and that further parts of portions of the one-piece closure cap created are overmolded onto such a part. It is also provided in particular in this construction that the lamellae (strip seal arrangement) are overmolded.
It is pointed out that the invention is not intended to be limited by the exemplary and preferred embodiments as described.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Figure 1 shows in schematic illustration an exemplary closure cap 1 in accordance with the invention.
The closure cap 1 shown in Figure 1 is entirely made as one piece and has a closure cap body 10 to which a closure cap lid 12 is hinged by way of a hinge constructed here as a film hinge 14.
The closure cap body 10 is provided with an upper cover or upper cover plate 16.
A closure cap opening 18 is provided in this cover plate 16. The opening 18 is circumferentially defined by a wall portion 20 which, when viewed in direction of the central longitudinal axis 22 of the closure cap l, protrudes upwardly and downwardly beyond the cover plate 16. It can also be provided that such a wall portion 20 extends only either upwardly or downwardly, or not beyond the cover plate 16 at all.
It is pointed out that the term "lower" in relation to the closure cap refers to that direction which - when the closure cap is mounted on a container - is directed towards the container, while the term "upper" refers to the opposite direction - facing away from the container.
In the embodiment according to Figure 1, the wall portion 20 is downwardly tapered, in particular comically tapered.
In the embodiment of Figure 1, an essentially annular projection 24 is provided on the inner side of the lid, which, when the lid is closed, especially sealingly engages the upper end of the wall portion 20. It can also be provided in this construction that such a projection 24 is shaped as a projecting plate or that no projection is provided at all with the inner surface of the lid - without a, projection being present - engaging the upper end of the wall portion 20.
It can further be provided that a retaining mechanism, schematically indicated by reference numeral 26, is provided which holds the cap lid 12 in its closed position relative to the closure cap body 10. In the embodiment according to Figure 1, a first wall 28 extends downwardly from the upper cover plate 16. This wall 28 is in the construction according to Figure 1 essentially cylindrically shaped and concentrical to the longitudinal axis 22. Lamellae 30, 32 are provided on the radially outwardly directed surface of this wall 28, which are circumferentially continuous and radially project from the wall 28. In the construction according to Figure l, two such lamellae are provided. The lamellae 30, 32 are spaced apart in axial direction or in the direction defined by the central longitudinal axis 22. Between the lamellae 30, 32, or between the lower of these lamellae 30, 32 and the cover plate 16, the wall 28 is completely circumferentially closed.
A second wall 30 is provided in the construction according to Figure 1 which extends about the central longitudinal axis 22 and, in particular, radially outwardly of the first wall 28.
The second wall 34 in the construction according to Figure 1 is cylindrically shaped and extends downwardly from the cover plate 16 and cylindrical to the central axis 22. In the construction according to Figure 1, the first wall 28 extends further down than the second wall 34.
An intermediate spacing is formed radially between the first wall 28 and the second wall 34 in which a container neck of a container can be received. The lamellae 30, 32 engage such a container neck or an inner wall of the container neck or the container -upon corresponding installation.
Radially inwardly of the first wall 28, a second intermediate space is provided or a channel 38 is formed. The opening 18 opens into this channel 38. The wall 28 is downwardly open so that when the closure 1 is mounted on a container, medium from the container can reach the opening 18 through the channel 38.
The opening 18 in the construction according to Figure 1 is concentrical to the central longitudinal axis 22, but can also be positioned non-concentrical.
A third wall portion 40 is further provided in the construction according to Figure l, which extends essentially in the direction of the central longitudinal axis 21 or extends downwardly at an angle to this longitudinal axis. The wall portion 40 in its construction according to Figure 1 is concentrical to the longitudinal axis 22 or to the first wall 28 and/or to the second wall 34.
Figure 2 shows an exemplary construction of a container 15 in accordance with the invention with an exemplary closure cap 1 in accordance with the invention.
The closure cap shown in Figure 2 is differentiated from the one shown in Figure 1 essentially in that in the construction according to Figure 2 the retaining mechanism 26 in the region of the lid facing away from the hinge 14 is omitted; however, such a retaining mechanism can also be provided in the construction according to Figure 2. The closure cap 1 shown in Figure 2 is further distinguished from the one shown in Figure 1 in that in the construction according to Figure 2 an annular projection which when the lid 12 is closed engages the upper side of the upper cover plate 16 or the wall portion 20, is omitted.
Instead, a plug 52 is provided in the construction illustrated in Figure 2 which projects from the underside of the lid 12 and extends into the closure cap opening 18 when the lid is closed, especially sealingly. The plug 52 can have a conical shape, for example.
The container shown in Figure 2 has exactly one container opening 54. However, it can principally also be provided that such a container 50 has several container openings.
At the container opening 54, the container 50 further has a container neck 56.
This container neck 56 has an essentially cylindrical shape and extends into the radially intermediate space 36 between the first wall 28 and the second wall 34. In the construction shown in Figure 2, the container neck 56 extends into the intermediate space 36 in such a way that the lamellae 30, 32 engage the inner wall of the container neck 56.
Furthermore, the inner surface of the second wall 34 engages in this construction the outer surface of the container neck 56. However, an intermediate space or clearance can also be provided. The lamellae 30, 32 engage the inner wall or inner surface of the container neck.
In the construction according to Figure 2, the inner surface of the second wall 34 a,s well as the outer surface of the container neck 56 are essentially unprofiled.
However, a profiled construction, especially a thread, can also be respectfully provided.
Figure 3 shows in schematic illustration a further exemplary embodiment of a container 50 in accordance with the invention with an exemplary closure cap in accordance with the invention.
In the construction in accordance with Figure 3 an outer thread 60 provided on the outer surface of the container neck 56 meshes with an inner thread 62 provided on the inner surface of the second wall 34. A third wall 40 positioned radially outwardly of this second wall is omitted in this construction according to Figure 3, but can also be provided.
Furthermore, three circumferential lamellae 30, 32, 64 are provided in the construction according to Figure 3. This is also a purely exemplary construction; only two lamellae can also be provided, as well as four, five or more than five lamellae. In the construction according to Figure 3, these lamellae often engage the inner surface of the container neck 56.
In the structure according to Figure 3, the closure cap 1 includes a plug 52 positioned on the inner side of the lid 12. In this exemplary embodiment -contrary to the construction according to Figure 2 - no wall portion 20 is provided which extends at the closure cap opening upwardly and downwardly beyond the upper cover plate 16.
It can be provided that the plug 52 - especially in co-operation with the opening 18 -apart from a sealing effect also provides a retaining effect. This can also be provided in the construction according to Figure 2.
Figure 4 shows a further exemplary construction of a container 50 in accordance with the invention with an exemplary closure cap 1 in accordance with the invention.
The closure cap 1 in the construction according to Figure 4 is distinguished from the one shown in Figure 3 essentially in that it is not provided with a closure cap opening 18, but that the upper cover plate - at least within the regions surrounded by the first wall 28 - is free of a closure cap opening and also does not have a closure cap lid 12 hinged by way of a hinge 14. Thus, the exemplary embodiment illustrated in Figure 4 of a closure in accordance with the invention, is a pure screw-on closure which is screwed onto the container by way of engaging a thread 62 on the cap with a thread 60 on the container neck.
A retaining mechanism can also be provided in place of such a thread. It can also be provided that the inner surface of the second wall 34 as well as the outer surface of the container neck 56 is constructed as shown in Figure 2.
Figure 5 shows a schematic illustration and exemplary container in accordance with the invention with an exemplary closure cap 1 in accordance with the invention.
The same as the container 50 illustrated in Figure 4, the container 50 of Figure 5 is provided on the outer surface of the container neck 56 with an outer thread 60 which is constructed to mesh with an inner thread 62 of the closure cap 1. While in the construction shown in Figure 4 this outer thread extends essentially up to the upper end of the container neck 56, a thread free region is provided on the outer surface of the container neck in the construction shown in Figure 5 above the outer thread 60, which region is engaged by the (seal) lamellae 30, 32 on the closure cap 1. Such a region can also be provided below the outer thread 60, and in particular on a radially outwardly projection, whereby the lamellae can be positioned in a radial backset of the wall 70.
These (seal) lamellae 30, 32 which in the construction according to Figure 4 are provided on the outer surface of a wall 28 extending in longitudinal direction of the closure cap, are in the embodiment according to Figure 5 positioned on the inner surface of a wall 70 extending about the central longitudinal axis 22 and project radially inwardly therefrom.
The closure cap 1 in the embodiment according to Figure 5 has only one wall 70 extending essentially about the longitudinal axis 22.
The container 50 shown in Figure 6 corresponds essentially to the one shown in Figure 5. The closure cap 1 shown in Figure 6 is distinguished from the one shown in Figure 5 essentially in that a dispensing opening 18 is provided in the one shown in Figure 6 in the upper cover plate and a hinged lid 12 for the opening and closing of the dispensing opening 18 is provided which is connected by way of a hinge, especially a film hinge 14.
Figure 7 shows a container 50 with a closure cap 1. The container 50 is distinguished from the one shown in Figure 2 in that the container neck 56 has a thread 60 on its outer surface which can be meshed with an inner thread 62 provided on the lid 12.
The closure cap 1 shown in Figure 7 is distinguished from the closure cap 1 shown in Figure 2 especially in that the second wall 34 is provided with an inner thread 62, in that no hinged lid 12 is present, and in that the upper cover plate 16 has no through going opening 18.
However, the embodiment shown in Figure 7 can be constructed without a thread 60, 62 as shown in Figure 2, or with a thread 60, 62.
FIELD OF THE INVENTION
The invention relates to closure caps for containers having a container opening, to containers with a closure cap, as well as to a process for the manufacture of closure caps.

Different constructions for closure caps for containers axe already known. For example, closure caps are known which cover container openings for the closure thereof and are moved away from the region of the container opening for the opening thereof. An example for such prior art are conventional screw-on caps, which often have a thread which for closing is meshed with a thread at the container opening, often on a container neck. It is normally provided in those constructions that the closure caps in the open condition of the container opening are completely separate from the container.
Such constructions are used, for example, for the packaging of hygiene articles, for example toothpaste, shower gels, shampoos or the like, or for the packaging of food, for example, ketchup or the like.
Closure caps are also known in which the closure cap itself has a further opening which can be opened or closed. Such closure caps are generally applied at the container opening, whereby the removal of stored medium from the container is most often made possible by the opening and closing of only the opening in the closure cap, while the closure cap remains on the container during the opening.

It is further known to insert a separate insert into the container opening which insert is provided with an opening through which medium can be removed from the container. Those inserts are constructed to produce an essentially sealed connection between the insert and the container so that the medium can exit the container only through the opening in the insert. A closure cap, for example, is then screwed or pressed onto this insert by which the opening in the insert or the container can be opened and closed.

The closing and opening is rather to be understood as conditions in which medium can be dispensed or not dispensed from the container or the combination of container and closure.
The closure cap in accordance with the invention includes at least one circumferentially continuous wall portion. The latter extends especially about a longitudinal axis of the closure cap.
It is further provided in accordance with the invention that a strip seal arrangement with at least two lamellae is provided, which are spaced apart in axial direction of the closure cap and combined into one piece with the closure cap.
It can be further provided that the closure cap has a retaining portion for holding it on a container. Such a retaining portion can, for example, be part of a snap closure, or a thread. It can also be provided that the strip seal arrangement is a retaining arrangement or part of a retaining arrangement. The term "retaining arrangement" is to be understood especially to define a retaining arrangement - possibly in co-operation with a counter retaining arrangement - which provides that the closure cap - upon corresponding positioning - cannot be released from the container under the force of its own weight. It can also be provided that the retaining arrangement is constructed such that a certain minimum force is required for detachment from the container. The retaining arrangement can also be in the form of a surface which can be frictionally connected with a surface region of the container or a container neck.
Preferably, the closure cap includes a cap body as well as a hinged lid connected thereto. The closure can also be constructed as a screw-on closure.
Especially, the closure cap can also be a screw-on closure which - when screwed onto a container or container neck - clears a corresponding container opening when the screw connection is released. However, it can also be provided that an additional opening is provided in the closure cap which can be closed, for example, by a hinged lid, whereby this closure cap can be screwed onto a container neck or a container.
In a preferred embodiment, the closure cap has a hinged lid which is connected to the cap body by way of a film hinge. Other hinges can also be used.
Several or all lamellae of the strip seal arrangement can be of annular shape and continuous. Especially, they can have a washer type shape. Several or all lamellae of the strip seal arrangement can be of essentially the same shape. However, they can also have different shapes.
In a preferred embodiment, several or all lamellae of the strip seal arrangement are essentially positioned parallel to one another. However, they can also be arranged at an angle to one another. The strip seal arrangement preferably includes two lamellae.
However, the strip seal arrangement can also include three, four, five or more than five lamellae. The lamellae of the strip seal arrangement can be positioned on the same wall or the same wall portion. However, they can also be positioned on different wall portions which are positioned, for example, to be opposite one another. In a preferred embodiment, the lamellae of the strip seal arrangement extend essentially radially relative to the longitudinal axis of the closure cap.
It can also be provided that the closure cap has a cap body without an additional hinged lid. This is the case, for example, with a closure cap constructed as a screw-on closure which does not include a further dispensing opening separate from the container opening.
The cap body can be provided at its upper end with a cover plate. Such a cover plate can have a planar or non-planar shape and can be of constant or variable thickness.
Such a cover plate is especially an upper cover. However, it need not be, although this can also be the case, the uppermost cover of such a cap. For example, in a closure cap with hinged cap lid, an upper cover plate can be provided which has a dispensing opening and can be closed - in the closed condition - by a lid position above the cover plate.
The language "at its upper end" therefore does not necessarily mean that the cover plate must actually form the upper end, although this variant is also preferred.
In a preferred embodiment, a first wall is provided which is circumferentially continuous and extends about a longitudinal axis or central longitudinal axis of the closure cap, from which first wall several lamellae extend essentially radially. It can be provided that these lamellae extend radially inwardly from this wall, or radially outwardly. The first wall can be, for example, concentrical to the central axis. It can be provided that this wall extends up to an upper cover plate. In such a construction, it can be especially provided that the circumferentially closed first wall is completely circumferentially closed between these lamellae and the upper cover plate.
The first wall can have a cylindrical contour, for example. It can also have -especially viewed in longitudinal direction of the closure cap - differently oriented portions. Especially the first wall can be constructed such that it has a cylindrical contour as well as an adjacent portion reoriented by 180 degrees, which is then again followed by a cylindrical portion. Lamellae can be provided, for example, at this further cylindrical portion. Other constructions are also preferred. In a preferred construction, a first channel is provided which extends radially inwardly of the first wall in longitudinal direction of the closure cap and which is open at its lower end. The lower end is thereby especially that end which when the closure cap is positioned or mounted on the container is directed towards the container.
In a preferred embodiment, an upper cover plate is provided in the closure cap which has a dispensing opening that opens into the first channel.
It is further preferred that the closure cap has several radia,lly spaced walls. Such walls can be, for example, concentric to one another. Such walls can be respectively cylindrically shaped or have other shapes. It can also be provided that three walls of the closure cap are provided which extend essentially in longitudinal direction of the closure cap and are radially spaced from one another. Such walls can respectively extend about a central longitudinal axis of the closure cap. They can respectively enclose the same or different angles with such a central longitudinal axis. They can have a straight or curved shape or other shape in longitudinal direction of the closure cap. Especially preferred are two radially spaced walls of which one has essentially radially extending lamellae of the strip seal arrangement and which walls are spaced such that a container neck of a container can be received between the walls in such a way that the lamellae respectively engage the container neck over the whole circumference thereof.
It is fuxther preferred that the closure cap is provided with a thread or a thread portion by which the closure cap can be connected with a container, especially removably connected. Other connecting mechanisms which allow a releasable connection between the closure cap and the container are also preferred. It can be provided especially that the closure cap is provided with a snap closure or part of a snap closure. A
"complementary portion" of such a snap closure can be provided, for example, on the container or the container neck. In a preferred embodiment, two radially spaced walls of the closure cap are provided which extend essentially in longitudinal direction of the closure cap and define an intermediate space - as already described - in which the container neck of a container can be received. In such a construction, it is especially preferred that lamellae of the strip seal arrangement extend from one of these walls and in particular on that side which is facing the other one of these walls. According to an especially preferred embodiment, a thread or threaded portion is provided on the other of these walls.
Especially preferably the other one of these walls is the one located radially further outwardly.
A thread or threaded portion can also be provided on a wall of the closure cap extending in longitudinal direction of the closure cap, and lamellae of a strip seal arrangement can be provided on the same wall. This can be especially 'achieved in that the lamellae are positioned above the thread or threaded portion.
The thread can he an inner thread or an outer thread.
The closure cap as a whole is preferably formed in one piece.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Figure 1 shows in schematic illustration an exemplary closure cap 1 in accordance with the invention.
The closure cap 1 shown in Figure 1 is entirely made as one piece and has a closure cap body 10 to which a closure cap lid 12 is hinged by way of a hinge constructed here as a film hinge 14.
The closure cap body 10 is provided with an upper cover or upper cover plate 16.
A closure cap opening 18 is provided in this cover plate 16. The opening 18 is circumferentially defined by a wall portion 20 which, when viewed in direction of the central longitudinal axis 22 of the closure cap l, protrudes upwardly and downwardly beyond the cover plate 16. It can also be provided that such a wall portion 20 extends only either upwardly or downwardly, or not beyond the cover plate 16 at all.
It is pointed out that the term "lower" in relation to the closure cap refers to that direction which - when the closure cap is mounted on a container - is directed towards the container, while the term "upper" refers to the opposite direction - facing away from the container.
In the embodiment according to Figure 1, the wall portion 20 is downwardly tapered, in particular comically tapered.
In the embodiment of Figure 1, an essentially annular projection 24 is provided on the inner side of the lid, which, when the lid is closed, especially sealingly engages the upper end of the wall portion 20. It can also be provided in this construction that such a projection 24 is shaped as a projecting plate or that no projection is provided at all with the inner surface of the lid - without a, projection being present - engaging the upper end of the wall portion 20.
It can further be provided that a retaining mechanism, schematically indicated by reference numeral 26, is provided which holds the cap lid 12 in its closed position relative to the closure cap body 10. In the embodiment according to Figure 1, a first wall 28 extends downwardly from the upper cover plate 16. This wall 28 is in the construction according to Figure 1 essentially cylindrically shaped and concentrical to the longitudinal axis 22. Lamellae 30, 32 are provided on the radially outwardly directed surface of this wall 28, which are circumferentially continuous and radially project from the wall 28. In the construction according to Figure l, two such lamellae are provided. The lamellae 30, 32 are spaced apart in axial direction or in the direction defined by the central longitudinal axis 22. Between the lamellae 30, 32, or between the lower of these lamellae 30, 32 and the cover plate 16, the wall 28 is completely circumferentially closed.
A second wall 30 is provided in the construction according to Figure 1 which extends about the central longitudinal axis 22 and, in particular, radially outwardly of the first wall 28.
The second wall 34 in the construction according to Figure 1 is cylindrically shaped and extends downwardly from the cover plate 16 and cylindrical to the central axis 22. In the construction according to Figure 1, the first wall 28 extends further down than the second wall 34.
An intermediate spacing is formed radially between the first wall 28 and the second wall 34 in which a container neck of a container can be received. The lamellae 30, 32 engage such a container neck or an inner wall of the container neck or the container -upon corresponding installation.
Radially inwardly of the first wall 28, a second intermediate space is provided or a channel 38 is formed. The opening 18 opens into this channel 38. The wall 28 is downwardly open so that when the closure 1 is mounted on a container, medium from the container can reach the opening 18 through the channel 38.
The opening 18 in the construction according to Figure 1 is concentrical to the central longitudinal axis 22, but can also be positioned non-concentrical.
A third wall portion 40 is further provided in the construction according to Figure l, which extends essentially in the direction of the central longitudinal axis 21 or extends downwardly at an angle to this longitudinal axis. The wall portion 40 in its construction according to Figure 1 is concentrical to the longitudinal axis 22 or to the first wall 28 and/or to the second wall 34.
Figure 2 shows an exemplary construction of a container 15 in accordance with the invention with an exemplary closure cap 1 in accordance with the invention.
The closure cap shown in Figure 2 is differentiated from the one shown in Figure 1 essentially in that in the construction according to Figure 2 the retaining mechanism 26 in the region of the lid facing away from the hinge 14 is omitted; however, such a retaining mechanism can also be provided in the construction according to Figure 2. The closure cap 1 shown in Figure 2 is further distinguished from the one shown in Figure 1 in that in the construction according to Figure 2 an annular projection which when the lid 12 is closed engages the upper side of the upper cover plate 16 or the wall portion 20, is omitted.
Instead, a plug 52 is provided in the construction illustrated in Figure 2 which projects from the underside of the lid 12 and extends into the closure cap opening 18 when the lid is closed, especially sealingly. The plug 52 can have a conical shape, for example.
The container shown in Figure 2 has exactly one container opening 54. However, it can principally also be provided that such a container 50 has several container openings.
At the container opening 54, the container 50 further has a container neck 56.
This container neck 56 has an essentially cylindrical shape and extends into the radially intermediate space 36 between the first wall 28 and the second wall 34. In the construction shown in Figure 2, the container neck 56 extends into the intermediate space 36 in such a way that the lamellae 30, 32 engage the inner wall of the container neck 56.
Furthermore, the inner surface of the second wall 34 engages in this construction the outer surface of the container neck 56. However, an intermediate space or clearance can also be provided. The lamellae 30, 32 engage the inner wall or inner surface of the container neck.
In the construction according to Figure 2, the inner surface of the second wall 34 a,s well as the outer surface of the container neck 56 are essentially unprofiled.
However, a profiled construction, especially a thread, can also be respectfully provided.
Figure 3 shows in schematic illustration a further exemplary embodiment of a container 50 in accordance with the invention with an exemplary closure cap in accordance with the invention.
In the construction in accordance with Figure 3 an outer thread 60 provided on the outer surface of the container neck 56 meshes with an inner thread 62 provided on the inner surface of the second wall 34. A third wall 40 positioned radially outwardly of this second wall is omitted in this construction according to Figure 3, but can also be provided.
Furthermore, three circumferential lamellae 30, 32, 64 are provided in the construction according to Figure 3. This is also a purely exemplary construction; only two lamellae can also be provided, as well as four, five or more than five lamellae. In the construction according to Figure 3, these lamellae often engage the inner surface of the container neck 56.
In the structure according to Figure 3, the closure cap 1 includes a plug 52 positioned on the inner side of the lid 12. In this exemplary embodiment -contrary to the construction according to Figure 2 - no wall portion 20 is provided which extends at the closure cap opening upwardly and downwardly beyond the upper cover plate 16.
It can be provided that the plug 52 - especially in co-operation with the opening 18 -apart from a sealing effect also provides a retaining effect. This can also be provided in the construction according to Figure 2.
Figure 4 shows a further exemplary construction of a container 50 in accordance with the invention with an exemplary closure cap 1 in accordance with the invention.
The closure cap 1 in the construction according to Figure 4 is distinguished from the one shown in Figure 3 essentially in that it is not provided with a closure cap opening 18, but that the upper cover plate - at least within the regions surrounded by the first wall 28 - is free of a closure cap opening and also does not have a closure cap lid 12 hinged by way of a hinge 14. Thus, the exemplary embodiment illustrated in Figure 4 of a closure in accordance with the invention, is a pure screw-on closure which is screwed onto the container by way of engaging a thread 62 on the cap with a thread 60 on the container neck.
A retaining mechanism can also be provided in place of such a thread. It can also be provided that the inner surface of the second wall 34 as well as the outer surface of the container neck 56 is constructed as shown in Figure 2.
Figure 5 shows a schematic illustration and exemplary container in accordance with the invention with an exemplary closure cap 1 in accordance with the invention.
The same as the container 50 illustrated in Figure 4, the container 50 of Figure 5 is provided on the outer surface of the container neck 56 with an outer thread 60 which is constructed to mesh with an inner thread 62 of the closure cap 1. While in the construction shown in Figure 4 this outer thread extends essentially up to the upper end of the container neck 56, a thread free region is provided on the outer surface of the container neck in the construction shown in Figure 5 above the outer thread 60, which region is engaged by the (seal) lamellae 30, 32 on the closure cap 1. Such a region can also be provided below the outer thread 60, and in particular on a radially outwardly projection, whereby the lamellae can be positioned in a radial backset of the wall 70.
These (seal) lamellae 30, 32 which in the construction according to Figure 4 are provided on the outer surface of a wall 28 extending in longitudinal direction of the closure cap, are in the embodiment according to Figure 5 positioned on the inner surface of a wall 70 extending about the central longitudinal axis 22 and project radially inwardly therefrom.
The closure cap 1 in the embodiment according to Figure 5 has only one wall 70 extending essentially about the longitudinal axis 22.
The container 50 shown in Figure 6 corresponds essentially to the one shown in Figure 5. The closure cap 1 shown in Figure 6 is distinguished from the one shown in Figure 5 essentially in that a dispensing opening 18 is provided in the one shown in Figure 6 in the upper cover plate and a hinged lid 12 for the opening and closing of the dispensing opening 18 is provided which is connected by way of a hinge, especially a film hinge 14.
Figure 7 shows a container 50 with a closure cap 1. The container 50 is distinguished from the one shown in Figure 2 in that the container neck 56 has a thread 60 on its outer surface which can be meshed with an inner thread 62 provided on the lid 12.
The closure cap 1 shown in Figure 7 is distinguished from the closure cap 1 shown in Figure 2 especially in that the second wall 34 is provided with an inner thread 62, in that no hinged lid 12 is present, and in that the upper cover plate 16 has no through going opening 18.
However, the embodiment shown in Figure 7 can be constructed without a thread 60, 62 as shown in Figure 2, or with a thread 60, 62.
