Description

CLOSURE FOR VESSELS, IN PARTICULAR FOR BOTTLES AND CONTAINERS

The invention relates to the field of closure systems for vessels, in particular bottles, and relates to a closure for closing a vessel opening. The closure comprises a first closure body having a receiving opening and a second closure body having a central closure member for closing the vessel opening in a direction of closure directed towards the vessel opening, and a holding member adjoining the closure member for gripping a neck region of the vessel opening on the outside, wherein the second closure body in FIG mounted state of the closure is guided at least partially through the receiving opening and is surrounded by this, and the first closure body includes a pressing member, wherein the closure body are configured so that the pressing member in the assembled state of the closure occupies a pressing position in which the holding member of the second Closure body is pressed against a neck region of the vessel opening.

STATE OF THE ART

From the prior art a variety of different closure systems for vessels such as bottles and containers are known. Which closure system is ultimately preferred depends on the requirements placed on such a closure system. An important criterion is, for example, reclosability. So it is for certain applications z. For example, in the area of the food industry or in the field of pharmacy and medicine, it is stipulated that a closure may not be re-closable. Thereby is z. B. achieved that any residual amounts after opening the vessel can no longer be stored. Furthermore, the containers with the original closure can no longer be used for the storage of other substances. So z. B. known in the field of beverage bottles, the so-called crown cork closures. The crown cap is a circular piece of sheet metal, which is provided with a sealing insert. The edge of the sheet metal piece is bent crown-shaped when closing the bottle. The bottle cap serves to seal beverage bottles airtight. To open a bottle capped by a bottle cap a tool, usually a bottle opener is needed. When opening the bottle, the bottle cap is irreversibly damaged, so that it is no longer suitable for reclosing.

In the consumer goods sector, the closures must be easy to use, especially for older and handicapped people. In this context, the criterion of opening the shutter with or without tools also plays a role. It goes without saying that a closure that can be operated without a tool has a significant advantage in that there is no need to carry an opening tool. Tool-free to open closures are z. B by screwing or pulling on a closure part or by folding a closure part open. The opening types mentioned have the disadvantage that the corresponding closure part must always be grasped in a certain way with the fingers of one hand. This significantly reduces the ease of use, especially for those users in whom the fine motor skills of the hands is limited.

Furthermore, depending on the application, production costs and environmental protection also play an important role. With regard to the latter criterion, for example, when opening a closure, it is not intended that a large number of separate closure parts be obtained. For example, EP-A-1 342 671 describes a closure for closing a bottle with a first closure part containing elastic lamellae and with a closure cap. To close the closure, the first closure part is placed over the bottle opening. Subsequently, the cap is placed on the first closure part and fixed. As a result of this process, the lamellae are pressed against the neck of the bottle, with projections on the lamellae engaging under a shoulder formed on the bottleneck. As a result, the closure is secured against axial displacement in the opening direction. To open the closure, the cap is removed again. This closure also has the disadvantage that parts of the closure must be gripped at least when opening by hand.

PRESENTATION OF THE INVENTION

It is an object of the invention to provide a closure of the type mentioned, which extremely simple, i. can be opened without special fine motor skills, as well as without tools, and which is also executable as a non-reclosable one-way closure. Furthermore, as few separate closure parts as possible should arise when the closure is opened.

This object is achieved by the characterizing features of claim 1. Particular developments or embodiments of the invention are contained in the dependent claims.

Thus, the invention is characterized in that the first closure body forms a pressurization area for opening the closure, wherein the first and second closure body are designed such that by pressurization in the closing direction on the Druckbeaufschlagungsbereich the Pressing member by a displacement of the first closure body relative to the second closure body in the closing direction, which corresponds to the printing direction, is moved from the contact pressure in a release position, such that the retainer or its holding elements in the radial direction to the vessel opening from its closed position to an open position can move and in this way the shutter is opened.

The pressurization area is preferably opposite to the receiving opening, in particular the receiving opening arranged opposite lying.

The vessel is preferably bottles or containers with an opening and an adjoining neck portion or area, which is effective in closing. Closure means that the said neck portion cooperates with the closure during closure and opening of the vessel. The term neck section or area is not limited to bottlenecks but should z. B. also include a collar-shaped configuration of the vessel opening with. The vessels are used, for example, the inclusion of liquids such as liquid foods, eg. As drinks, or medicine and detergents. However, the vessels can also be used for receiving bulk material, such as powders and tablets, or for receiving other goods.

The two closure bodies and the vessel opening are preferably arranged along a central closure axis and in particular coaxially or concentrically with one another during the creation of the closure and in the assembled state of the closure. The closure axis is preferably perpendicular to the vessel opening. The two closure bodies are preferably rotationally symmetrical. The vessel opening is designed, for example, as a circular opening. Accordingly, the closure body with respect to their circumferences are also circular. The pressurization takes place in the direction of the receiving opening of the first closure body. The pressurization takes place, for example, by hand, especially with the palm of your hand. The pressing member can be formed by an edge portion surrounding the receiving opening. The pressing member may be formed in particular by the annular edge which defines the receiving opening. This edge or edge portion may be formed closed. Accordingly, the contact pressure in this case proves to be unyielding or slightly yielding to radial forces.

The diameter of the receiving opening may be equal to or greater than the diameter of the closure member of the second closure body. Furthermore, the diameter of the receiving opening may be equal to or greater than the largest diameter of the closure effective neck portion of the vessel.

The holding member is designed such that it engages outside the closure of the vessel via the closure-effective neck portion of the vessel. The holding member is preferably elastic or resilient. The holding member preferably comprises a plurality of holding elements. These may be formed, for example, as lamellae, which term is to be understood also arms, flags, lugs or aprons. The holding elements or lamellae can also be connected to one another laterally, for. B. via flexible wall connections. The retainer can also be used as a continuous, z. B. the closure member annular circumferential, elastic and flexible lip may be formed. The holding member or its holding elements can or can be arranged radially or annularly, in particular in a circular ring around the central closure element, and be elastically movable radially relative to the latter. The holding member can on the closure member be attached or molded. The holding member and the closure member preferably form an integral component.

The closure member is that part of the second closure body which comes to lie above the vessel opening and closes or seals it. The closure member may accordingly contain a plug, which is introduced when closing the vessel in the vessel opening. The seal is here inter alia by the radial contact pressure of the plug in the neck portion. The plug is z. B. integrally formed on the closure member or integral part desselbigen. The plug can be designed as a cylinder or ring body.

However, the closure member need not necessarily include a plug to create the seal. The seal can also be generated by an axial contact pressure of the closure member or a sealing element associated therewith on the upper side of the vessel opening. Said sealing element or the sealing surface is preferably an integral part of the closure member. In addition, sealing means, such as sealing lips or sealing rings can be integrated into the closure member. If a stopper is provided, a depression, in particular an annular depression, is expediently formed between the stopper and the holding member, into which the closure-effective neck section engages when the vessel is closed.

The holding member or its holding elements is or are z. B. laterally obliquely or obliquely radially from the closure member. In the opening position, the largest diameter defined by the holding elements can be larger than the receiving opening of the first closing body. This feature is of particular importance in terms of the design of a one-way closure, as described below. The elastic holding member and in particular the elastic holding elements on the second closure body are preferably designed such that they are in the pressing position of the pressing member, ie in the closed position under a bias.

The pressurization region may be a section lying above the vessel opening and / or above the neck section, in particular a wall section, of the first closure body. In particular, it can be an outwardly curved wall region of the first closure body. The pressurization area can be arranged radially outwards in the central closure axis or with respect to the closure axis. The pressurization area may in particular be an annular surface area arranged concentrically around the central closure axis. The first and second closure body are preferably designed such that between the second closure body, in particular the closure member, and the Druckbeaufschlagungsbereich of the first closure body, a sliding space is formed, such that the Druckbeaufschlagungsbereich can be pressed to open the closure in the direction of this sliding space. Said sliding space may be formed as a cavity or it may be covered with a compressible element, such as foam.

The first closure body may be formed according to a particular embodiment as a closure cap, in particular as a closed closure cap, with a Aufnahmeöffhung. The pressurization area is formed by a cap portion or wall portion opposite the receiving opening.

The first closure body preferably forms a receiving space, which is designed such that it at least partially or the second closure body can completely absorb. The first closure body may further form an undercut region, in particular an undercut cavity. The undercut area is part of the recording room. The undercut region is preferably designed annular.

The first and second closure body are preferably designed such that the receiving space of the first closure body completely receives the second closure body in the open state of the closure and the at least partially relaxed holding member or its holding elements engage in the undercut region of the first closure body and so sliding out of the second Prevent closure body from the first closure body. This development of the invention is particularly important in terms of a disposable closure, because in this way the captured in the first closure body, second closure body with its holding member or its holding elements can not be brought into a closed position. The user is also not possible, resp. at most with great effort and with the aid of tools to separate the closure body in order to reclosure of the container from each other. So that the closure resp. the first closure body is secured in its closed position against displacement parallel to the closure axis, appropriate means are provided, which prevent this. The means should be designed so that the first closure body in the closing direction, which also corresponds to the opening direction, only by applying a certain amount of force, as it is necessary to open the closure, is displaceable, and that the first closure body with the container closed against the closing direction or contrary to the mounting direction is not displaced or can not be deducted. The means may comprise interlocking elements on the holding member and the pressing member. The interlocking elements can, for. B. form a snap connection in which an adherend, suitably the retainer, elastically deformed and hooked with the other joining part, suitably the pressing member. The entanglement can be designed so that it causes anchoring of the first closure body in a direction of movement opposite to the mounting direction. In this way it is ensured that the once assembled closure can not be dismantled in its original configuration contrary to the mounting direction. The removal of the closure thus works only on the intended opening process.

Thus, the holding member or its holding elements preferably directed to the vessel opening projections, z. B. in the form of thickening, especially noses, hooks, lips or beads. The projections are provided for engagement in a recess or on a shoulder at the neck portion of the vessel. For this purpose, the vessels or bottles have, viewed in the closing direction, a neck region with a smaller diameter than the diameter of a preceding neck region, on the neck section. The projections now engage in the region of the neck region with the smaller diameter. The closing direction is the direction in which the closure body must be moved in order to create the closure. The closing direction is parallel to the closure axis.

To secure the contact pressure in the pressing position, in particular against a displacement against the closing direction, the holding member or its holding elements on the side facing away from the vessel opening side a latching point, preferably in the form of a recess or a paragraph, for the latching engagement of the pressing member, in particular of said edge portion, in the pressing position. The recess may be formed as a groove. The recess can also be attached to the pressing member, wherein the locking point in this case is designed as a projection. Furthermore, a snap mechanism is possible.

In addition, the closure may contain securing means which, in the activated state, fundamentally prevent the first closure body from being displaceable relative to the second closure body in the direction of the closure axis, in particular in the closing direction. The securing means can z. B. on the first and / or second closure body integrally formed and possibly interacting with each other elements. The securing means can z. B. be formed such that the securing or unlocking of the closure is done by a rotational movement of the first closure body relative to the second closure body. The mentioned securing elements on the first and / or second closure body are z. B. so designed to block in the backup position an axial movement of the first closure body to the second closure body out. The securing means can also be made of a shrink film drawn over the closure and the associated neck section of the vessel, which likewise prevents or at least considerably impedes axial movement of the first closure body. The first and / or second closure body may be made of plastic (eg polyethylene or polypropylene) or of metal. As a metal material is particularly spring steel or other metals with elastic properties, such. B. certain aluminum materials. The first and / or second closure body may also consist of a metal-plastic composite. The materials or material combinations have correspondingly elastic properties.

The closure or the first and / or second closure body can be produced, for example, by means of a single-stage or multi-stage injection molding process from plastic. It is particularly possible that the closure or the first and / or second closure body made of several different plastics z. B. are produced in a multi-stage injection molding. Thus, for example, the second closure body comprise a first plastic, from which z. B. the elastic holding member or its elastic holding elements are formed. A second plastic forms an integrated seal. Furthermore, a further plastic may be provided, which forms a vapor barrier. Incidentally, the same effect is also achieved by an integrated metallic foil or a metallic coating. It can also be provided in the following, the closure or the first and / or second closure body is made of a composite of different materials such as metal and plastic. Thus, for example, metal bodies, such as metal foils, can be inserted into the mold and overmolded with plastic or a plastic part can be injection-molded onto the metal body.

As already mentioned, the first and / or second closure body can be formed in one or more parts. It is also possible that the first and second closure body in one piece, z. B. by means of injection molding. In this case, the connections between the first and second closure body may contain predetermined breaking points which, when the two bodies are displaced relative to one another, ie. at a displacement of the first closure body in the closing direction, break. The compounds mentioned can also be flexible and dimensioned accordingly, so that they allow a displacement of the closure body in the above-mentioned manner, without being damaged itself.

The present invention has the advantage over the prior art that the closure by means of pressurization and best by means of a pressure pulse, z. B. a blow in the closing direction, can be opened. The size of the applied pressure force can of course in the interpretation of Closure be designed specifically based on the requirements of the closure. The opening can z. B. done by means of palms in a simple movement. In contrast to known closure systems no fine motor movements are required, as z. B. when screwing, unfolding, etc. is the case. The surrounding the Geiassöffnung neck portion forms when opening the shutter a natural stop for the cap, so that the opening process is always controlled independently of the applied pressure force. The application of a directed in the closing direction compressive force to open the vessel is surprising and unfamiliar to the user, as this is used to open a vessel to perform a direction of closure opposite or otherwise directed movement. The unfamiliar movement direction for opening the closure according to the invention creates the attraction of the unusual, which awakens the consumer's curiosity. This, in turn, can be of great advantage in the marketing of a product.

The function of the closure will now be explained in more detail with reference to an inventive embodiment, which is illustrated in the accompanying drawings. However, the function described with reference to this embodiment is not intended to be limited to said embodiment.

Figures la-ld: a cross-sectional view through a first embodiment of a closure according to the invention in various (assembly) positions; FIGS. 2-7: in each case a side elevation and a perspective view of the closure according to FIG. 1 a in different (assembly) positions;

FIGS. 8a-8m show a side elevation of a second embodiment of a closure according to the invention in various (assembly) positions.

The reference numerals used in the drawings and their meaning are listed in the list of reference numerals. Basically, the same parts are provided with the same reference numerals in the figures.

The closure 1 according to the invention in accordance with the first embodiment shown in FIGS. 1 to 7 serves to close a beverage bottle 4. This comprises a circular bottle opening 18 which is surrounded by a neck section 15. The neck portion has a circumferential bead and in the closing direction V thereupon an annular recess 16.

The closure 1 comprises a first closure body 2 in the form of a closure cap and a second closure body 3. The closure cap 2 includes a circular receiving opening 5 and a pressure application region 6 opposite the receiving opening 5. The receiving opening 5 is bordered by an annular edge section 10, which surrounds the pressure element 7 trains. The closure cap 2, starting from the slightly curved pressure application area 6 in the direction of the receiving opening 5, has a lateral, arcuately curved, bulbous contour. The largest diameter of the closure cap 2 is larger than the diameter D1 of the receiving opening, so that the closure cap 2 forms an undercut region 9. The second closure body 3 includes a closure member 12 with a plug 17 for insertion into the bottle opening 18. At the circular outer periphery of the closure member 12 is a holding member 1 1 with a plurality of holding elements l la..l ld arranged in the form of tab-shaped projections. For the sake of clarity, only four retaining elements l la..l ld are provided with reference numerals in the figures. The holding elements l la .. ld are directed towards the closure side 19 and stand in the relaxed state obliquely radially from the closure member 12 from. Between the holding elements l la..l ld and the plug 17, an annular space is formed, in which engages the neck portion 15 of the beverage bottle 4 when closing the bottle.

The holding elements l la..l l d each have a bead-shaped projection 13, which is directed to the Geiassöffnung 18 out. Further, the holding elements l l a..l ld on the opposite side facing away from the Geiassöffnung 18 side on a recess 14 in the form of a notch.

To close the bottle, which is usually done by the manufacturer, the second closure body 3 is placed with its closure member 12 on the bottle opening 18, so that the plug 17 engages in the bottle opening 18 (Figure la and 4a, 4b). The holding elements l la..l ld engage in this position, which corresponds to the so-called opening position PZ2 of the second closure body 3, outside via the neck portion 15 of the beverage bottle 4. The opening position PZ2 is characterized in particular by relaxed holding elements 1 1 a..1. 1 d, which are pushed over the bead-shaped widening of the neck portion 15 and laterally protrude slightly.

Subsequently, the closure cap 2 is placed on the second closure body 3. The closure body 2, 3 and the bottle opening 18 assume a concentric position to one another and are coaxial with the closure axis A. arranged. The cap 2 is now in the mounting position PE1. In the mounting position, the holding elements l la .. ld have a larger diameter D3 than the diameter Dl of the receiving opening 5. The diameter Dl of the receiving opening 5, however, is not smaller than the diameter D4 of the bead-shaped widening.

In a next step, the closure cap 2 is pressed parallel to the closure axis A in the direction of the bottle opening 18 via the second closure body 3 (FIGS. 1b and 5a, 5b). In this process, the holding elements 1 l a..l ld are pressed radially toward the bottle opening 18 and undergo a bias. Due to the now decreasing diameter D3 of the holding element arrangement, the closure cap 2 slides over the holding elements 11a to 11l until it engages with its edge section into the notches 14 on the holding elements 1a. The cap 2 has now reached the so-called pressing position PE2. It can also be quite generally provided that the first closure body screwed by means of a screw on the second closure body instead of being pressed and z. B. is guided in the latching position.

The holding elements l la .. l l d take their closure position PZ1 in this process by now these rest on the neck portion 15 and the projections 13 of the holding elements engage in the recess 16 on the neck portion 15. By this intervention, the closure 1 is blocked axially, so that the beverage ashes 4 remains permanently closed. In this position, a displacement chamber 8 is formed between the pressurization region 6 and the closure member 12.

To open the closure 1, a pressure force must now be exerted in the pressurization area 6 in the closing direction V which is sufficiently large to lift the edge portion 10 of the closure cap 2 out of the rest position and to move it in the closing direction V (FIGS. 1c and 6a, 6b). In this process the closure cap 2 is displaced relative to the second closure body 3 in the closing direction V, the pressure application area 6 being displaced into the displacement space 8 in the direction of the second closure body 3 or closure element 12. The closure cap 2 now slides with its receiving opening 5 completely over the holding elements 11 a.1.1 d, whereby the second closure body 3 is completely received by the receiving space of the closure cap 2. Since the receiving space has an undercut area 9, the pretensioned holding elements 11a.1.1d can at least partially relax again. The cap 2 is now in its release position PE3. In the present embodiment, the holding elements 1 1 a..11 d relax completely, causing the Halteelemente- arrangement assumes its original diameter D3 and the holding elements 1 la..lld again assume their opening position PZ2. So that the pressing member 7 can be released for opening the closure 1 from the locking position, for example, the material of the holding element l la..l ld can be compressible or elastic. Furthermore, it is also possible that the holding element 11 a .. lld at the height of the latching point 14 is not fully applied to the neck portion 15, so that the holding element ll a .. l ld when moving the pressing member 6 from the locking position in the closing direction for the purpose of opening the Closure 1 can be further pressed against the neck portion 15 and thus allows escape of the pressing member 7 from the locking position.

The closure cap 2 can now be lifted off the bottle opening 18 together with the second closure body 3, wherein the second closure body 3 is held in the receiving space of the closure cap 2 due to the larger diameter of the at least partially relaxed holding element arrangement relative to the diameter Dl of the receiving opening 5 or remains trapped therein (Figure 1 d and 7a, 7b). The closure 51 according to the invention according to the second embodiment shown in FIGS. 8a to 8m also serves to close a beverage bottle 54. This comprises a circular bottle opening 68 which is surrounded by a neck section 65. The neck portion 65 has a circumferential bead and in the closing direction V, followed by an annular recess

66 on.

The closure 51 comprises a first closure body 52 in the form of a closure cap and a second closure body 53. The closure cap 52 includes an annular receiving opening 55 and a pressure application region 56 arranged opposite the receiving opening 55. The receiving opening 55 is bordered by an annular edge section 60, which surrounds the pressure element 57 trains. The annular edge portion 60 with the pressing member 57 also forms an undercut area, in which the holding elements 61a..c are trapped in the axial direction after opening the closure.

The closure cap 52 has an insertion plug 59 extending in the closing direction V. The insert plug 59 is surrounded by the annular receiving opening 55 and extends in the closing direction V beyond the annular edge portion 60 addition.

The second closure body 53 includes a closure member 62 with a sealing plug 67 for insertion into the bottle opening 68. The sealing plug

67 is hollow cylindrical and open against the closing direction V open. The hollow cylindrical plug 67 is closed in the closing direction V and has a bottom. The bottom contains a bulge 70 directed towards the opening of the sealing plug. At the level of the opening of the sealing plug 67, a retaining member 61 with a plurality of retaining elements 61a..61c in the form of tab-shaped projections is arranged on its circular outer circumference. For the sake of clarity, only three retaining elements 61a..61c are provided with reference numerals in FIGS. 8a-8m. The holding elements 61a..61c are directed towards the closure side 69 and, in the relaxed state, project radially outward from the closure member 62. The holding elements 61 a..61c each have a bead-shaped projection 63, which is directed towards the vessel opening 68. Furthermore, the holding elements 61 a..61 c have an engagement point 64 on the opposite side facing away from the vessel opening 68. To close the bottle, which is usually done by the manufacturer, the second closure body 53 is placed with its closure member 62 on the bottle opening 68, so that the closure plug 67 engages in the bottle opening 68 (Figure 8a to 8c). The holding elements 61 a..61c are in this position radially outward from the neck portion 65 from.

Simultaneously with or subsequent to the introduction of the sealing plug 67 into the bottle opening 68, the closure cap 52 is placed on the second closure body 53. The insertion plug 59 of the closure cap 52 is inserted into the sealing plug 67.

The closure bodies 52, 53 and the bottle opening 68 occupy a concentric position relative to one another and are arranged coaxially with the closure axis A. The closure cap 52 is in the mounting position in FIGS. 8a to 8g. In a next step, the closure cap 52 is guided parallel to the closure axis A in the direction of the bottle opening 68 via the second closure body 53 (FIGS. 8d to 8h). In this process, the holding elements 61a..61 c are pressed by the circular pressing member 57 from its radially outwardly projecting position to the bottle opening 68 out. Since the holding elements 61a..61c are resiliently connected to the closure member 62, they experience a bias. Between the holding elements 61a..61c and the closure plug 67, an annular space is formed into which the neck portion 65 of the beverage bottle 54 engages.

The closure cap 52 slides in the closing direction V over the holding elements 61 a..61c until it engages with its pressure element 57 in the engagement points 64 on the holding elements 61 a..61c. The engagement points 64 may, for. B. be formed as elastic wall portions which yield the radial pressure force of the pressing member 57, so that this hooked into the engagement points 64. However, the engagement points 64 may also be formed as notches.

With the hooking of the pressing member 57 in the engagement points 64 to the holding member 61 a-61 c cap 52 has reached the closure position (Figure 8h).

Incidentally, it can also be provided that the first closure body screwed by means of a screwing on the second closure body instead of being pressed and z. B. is guided in the engaged position.

The holding elements are in the closed position of the neck portion 65 at. The projections 63 of the holding elements 61 a... 61 c engage in the depression 66 on the neck section 65. By this engagement, the shutter 51 is blocked axially, so that the beverage bottle 54 remains permanently closed. In this position, a displacement space 58 is also formed between the pressurization area 56 and the closure member 62. To open the shutter 51, a pressure force must now be exerted in the pressurization area 56 in the closing direction V which is sufficiently large to bring the edge portion 60 of the closure cap 52 out of the engagement position and to move it in the closing direction V (FIG. 8i). In this process, the closure cap 52 is displaced in the closing direction V relative to the second closure body 53, the pressure application area 56 being displaced into the displacement space 58 in the direction of the second closure body 53 or closure member 62. The closure cap 52 now slides with its receiving opening 55 or the pressing member 57 completely over the holding elements 61a..61c, whereby the holding member 61 of the second closure body 53 is received by the receiving space of the closure cap 52. Since the receiving space has an undercut area, the pretensioned holding elements 61a..61c can at least partially relax again. The cap 52 is now in its release position.

Thus, the pressing member 57 is releasable to open the shutter 51 from the engaged position, for example, the material of the holding member 61a..61 c be compressible or elastic. Furthermore, it is also possible that the holding element 61 a..61c at the height of the engagement point 64 is not completely applied to the neck portion 65, so that the holding member 61a..61 c when moving the Anpressorgans 56 from the engaged position in the closing direction for the purpose of opening the closure 51 is still pressed against the neck portion 65 and thus allows escape of the pressing member 57 from the engaged position. The closure cap 52 can now be lifted off the bottle opening 68 together with the second closure body 53 in the opening direction O, which is opposite to the closing direction V. The second closure body 53 is held in this process with its retaining member 61 in the receiving space of the cap 52 and remains trapped therein (Figure 8i - 8m).

The inventive closure according to the first and second embodiments is therefore available as a one-way closure, since it is not possible for the user to separate the two closure body again from each other to re-close the bottle. The inventive embodiments also have the further advantage that when opening the bottle only a single closure part is obtained, which must be disposed of.

Such a closure is suitable for. B. as a replacement for the well-known crown cork closure. The closure according to the invention has the advantage over the crown cork closure that it does not have to be opened with an opening tool. Furthermore, the closure has only round, smooth shapes in its outer regions, whereas the crown cork closure has sharp edges and points in the region of its crown, which constitute a risk of injury.

It goes without saying that the use of the closure according to the invention according to FIGS. 1 to 8 is not limited to beverage bottles, but is generally suitable for vessels with a vessel opening and a neck section.
