Description

The Invention relates to closures for a one Containing containers, in particular a bottle or the like of plastic, glass or the like, with a cap for sealing connection with one edge having neck of the container, with at least one in the area of the clear width of the neck around one Central axis of the cap around arranged knife edge for cutting a sealing film with axial displacement of the at least one Knife edge through the sealing film through, the knife edge at one of the cap by means of a flexible apron substantially held centrally and relative to the cap in the direction of the sealing film to be shifted receiving box is arranged, which is a zuzumischenden the contents of the container component contains and with an external thread owning central spigot on an upper transverse wall of the cap and one on top of it unscrewable screw cap with a arranged on the inner end wall Actuator, by means of which when screwing the screw cap on the center Trim the receptacle with its at least one knife edge in the direction of the sealing film is displaceable, this screw cap an initial screw, in which the sealing film is still unhurt, and after further Unscrewing has a Anschlagschraubstellung, in which the Closing foil from the at least one knife edge is pierced.

such closures serve to mix a content of the contents of the container during one Waiting or storage time separated from the main component of the container keep until the time of consumption has come is, in particular, premature impairment of quality or usability of the total contents, if necessary after Adding over time by aging od. Like. Occur could. With drinks or general foods, these are simply those Time at which the consumer wishes to enjoy the contents of the container or bottle while it is in the case of z. As chemicals, paints, varnishes, detergents od. Like. At the time of use is. In the case of food, it may be in the zuzumischenden Component z. B. to vitamins or mixtures thereof, at Paints or plastics to activators such as pigments or accelerators (eg oxidizing agent) etc.

From the publication WO 2004/113184 A2 a closure of this type is known in which the cap is designed as a first screw cap and the screw cap as a second screw cap. This known closure must be completely unscrewed from the container neck after the opening of the sealing film and the release of the container contents zuzumischenden ingredient, so the first screw together with the second screw cap, if you want to remove something from the mixed container contents. If you want to close the container after a partial removal of container contents again, then the closure must be screwed as a whole again. When unscrewing, when removing container contents, z. B. when drinking from a bottle, if their content is a drink, and when re-screwing the closure in order to reclosure of the container or bottle, the user needs both hands, however, by the separation of the closure from the container or the bottle There is always the risk that the closure could fall out of the hand of the user or drinker.

Further are closures known as so-called sports caps, which for opening and removing of container capacity only partially unscrewed, so on the neck of the Container or can remain in the bottle, because such a Sportscap has a removal opening, which also in only partial unscrewing is released and renewed Close screwing again leaves. Such sports caps allow to athletes, especially cyclists, while exercising drink without both hands to use and without being in danger, it may be the closure of the bottle to lose.

The The object underlying the invention is seen in a To provide closure of the type mentioned, the like is trained that he also suitable to fulfill the functions of a sportscap.

A second solution of the invention task is that

• a) the cap remains permanently on the neck of the container after sealing connection
• b) the screw cap has a pouring and / or drinking opening in the manner of a sportscaps, that
• c) is provided radially between the cap and the receiving sleeve at least a first passage for the container contents, that
• d) centrally between the cap and the receiving sleeve initially provided on a substantially radial inner surface of the cap fitting axial intermediate piston and slidably guided in a coaxial guide the transverse wall of the cap, which intermediate piston by abutment against the cap a seal between the container and the Screw cap and thus cause the environment and on the other hand in its displacement together with the receiving bushing the same and whose at least one knife edge concentrically relative to the closure film in an end position for the purpose of separating the sealing film to shift, in which end position the sealing film at least partially separated, the zuzumischende Part released into the container contents and between the intermediate piston and the cap still a second passage has been opened
• e) the screw cap on its inner side cover and the intermediate piston on its opposite end face as actuator each have concentrically a connection pair of a plunger and a counterpart receiving this, which engages one another axially immovable, the plunger and its counterpart are axially positioned relative to each other, in such a way that in the case of said further screwing on of the screw cap onto the central neck up to its stop screw position, the container contents can be released for a flow to the screw cap and its pouring and / or drinking mouth, by means of the further screwing onto the sealing foil displacing and thereby the seal between it and the cap releasing the intermediate piston, wherein the captured by the intermediate piston receiving sleeve pierces the sealing foil with its at least one knife edge, and that
• f) when screwing the screw cap in the opposite direction and thus back to its initial screw the intermediate piston can be brought back to the sealing engagement with the cap, such that the passage to the screw cap and the pouring is again interrupted.

This second solution essentially differs from the first solution explained above in that the actuating device and the receiving sleeve are formed as two separate parts. In this case, at the counterpart of the actuator of the sleeve having a rod approach is formed at its end facing the receiving socket as a piston. This piston is called in the following intermediate piston, since it is arranged between the receiving sleeve and the opposite end wall of the first screw cap. The receiving bushing can have as an axial contact surface for the intermediate piston a flat end face on which the intermediate piston come to rest and can take the receiving sleeve as soon as the screw cap on further screwing on the central nozzle displaces the receiving sleeve in the opening direction or moves, namely for the purpose piercing the sealing film.

• 1. Diese zweite Lösung lässt sich mit geringerem Aufwand herstellen und zusammenbauen. Zum einen lassen sich die Aufnahmebüchse und der Zwischenkolben als jeweils relativ einfach geformte Teile auch relativ einfach herstellen. Zum anderen kann der von der Aufnahmebüchse aufzunehmende und später zuzumischende Bestandteil eingesetzt und mit der Verschlussfolie eingeschlossen werden, während die Aufnahmebüchse auf ihrem im wesentlichen plan ausgebildeten Rücken liegend angeordnet ist, z. B. auf einem Montageband.
• 2. Sowohl bei der ersten als auch bei der zweiten Ausführungsform wird beim Aufschraubender zweiten Schraubkappe bis in deren Anschlagschraubstellung zwecks Eröffnens der Verschlussfolie und gegebenenfalls auch der Siegelfolie die flexible Schürze verformt, die ja der Aufnahmekapsel deren erforderliche Verlagerung oder Verschiebung gestatten muß. Es versteht sich, dass diese Schürze ungeachtet ihrer Flexibilität ihrer Verformung einen gewissen, wenn auch nicht sehr ausgeprägten, Widerstand entgegensetzt. Erfolgt dann ein erneutes Schließen des erfindungsgemäßen Verschlusses durch ein Verschrauben der zweiten Schraubkappe in entgegengesetzter Richtung, also zurück in deren Anfangsschraubstellung, dann muß bei der ersten Ausführungsform die Aufnahmebüchse bei entsprechender Rückbewegung auch der Schürze wieder mitgenommen werden, während bei der zweiten Ausführungsform die Aufnahmebüchse vorteilhafterweise zurückbleiben kann. Dass erneute Verschließen des Behälters bzw. der Flasche erfordert somit weniger Schraubkraft, was im Hinblick auf die gewünschte Möglichkeit zur Einhandbedienung von Bedeutung ist.

At first sight, this second solution may seem more complicated, more complicated and therefore less advantageous because of the splitting of the one-piece design of receiving bushing and actuating device present in the first embodiment. But this second solution has two major advantages over the first:

• 1. This second solution can be produced and assembled with less effort. On the one hand, the receiving bushing and the intermediate piston can also be relatively easily manufactured as relatively simply shaped parts. On the other hand, to be absorbed by the receiving sleeve and zuzumischende later component used and enclosed with the sealing film, while the receiving sleeve is arranged lying on its substantially planar formed back, z. B. on an assembly line.
• 2. Both in the first and in the second embodiment, the flexible apron is deformed when screwing the second screw cap in the Anschlagschraubstellung for the purpose of opening the sealing film and possibly also the sealing film, which must allow the receiving capsule their required displacement or displacement. It is understood that this apron, despite its flexibility, provides some, if not very marked, resistance to its deformation. If the closure according to the invention then closes again by screwing the second screw cap in the opposite direction, ie back into its initial screwing position, then in the first embodiment the receiving bushing must be taken along again with appropriate return movement of the skirt, while in the second embodiment the receiving bushing advantageously can stay behind. The fact that resealing the container or the bottle thus requires less screw force, which is important in terms of the desired possibility for one-handed operation.

The sealingly connecting the cap to the neck of the container done in different ways, for. B. by welding or by gluing etc. Most common However, at present, the formation of the cap according to the listed closest The prior art as a first screw cap, whereby the mentioned screw cap becomes a second screw cap. The difference is there in that explained at Prior art according to the mentioned Publication this first screw cap and thus the entire closure must be unscrewed, you want to the container contents arrive while in the subject invention, the cap after the sealing attachment at the bottleneck constantly can remain on it, even if it is the first screw cap is trained. Is she welded, sealed, shrunk or the like, then the stay is understood from the outset.

Therefore is the closure according to the invention preferably designed such that the cap as a first screw cap an internally threaded sleeve portion for screwing on an external thread having an edge-having neck of the container and the screw cap is designed as a second screw cap.

Thus, the invention particularly relates to a closure with a first screw cap, in particular made of plastic, od a sleeve portion having an internal thread for screwing onto an external thread of an edge having a neck of a container having a content, in particular a bottle od. Like. Plastic, glass od dergl., Has with at least one arranged in the region of the clear width of the neck about a central axis of the first screw around knife edge for severing a sealing film with axial displacement of the at least one knife edge through the closure film, the knife edge on one of the first screw cap by means a flexible apron is arranged substantially centrally and relative to the first screw cap in the direction of the closure film to be displaced receiving sleeve is arranged, which contains a content to be admixed the contents of the container, and with an external thread owning central neck on an upper transverse wall of the first screw cap and a screwed on the same second screw with a arranged on the inner end wall actuator, by means of which when screwing the second screw cap on the neck of the receiving sleeve with their mindes at least one knife edge in the direction of the closure film is displaceable, said second screw cap has a Anfangsschraubstellung in which the closure film is still unhurt, and after further unscrewing a Anschlagschraubstellung in which the closure film is pierced by the at least one knife edge.

The corresponding variant of the second solution of the invention task then consists in that

• a) the first screw cap after the sealing connection remains permanently on the neck of the container that
• b) the second screw cap in the manner of a sportscaps a pouring and / or drinking opening has, that
• c) is provided radially between the first screw cap and the receiving sleeve at least a first passage for the bottle contents, that
• d) centrally between the first screw cap and the receiving bushing initially provided on a substantially radial inner surface of the first screw cap axial intermediate piston and slidably guided in a coaxial guide the transverse wall of the first screw cap, which intermediate piston by abutment against the first screw a seal between to cause the container and the second screw cap and thus the environment and on the other hand in its displacement together with the receiving bushing the same and whose at least one knife edge concentrically relative to the sealing film in an end position for the purpose of separating the sealing film to shift is suitable, in this end position, the sealing film at least partially separated, the zuzumischende component released into the bottle contents and between the intermediate piston and the first screw cap, a second passage has been opened, that
• e) the second screw cap on its inner side cover and the intermediate piston on its opposite end face as actuating means each concentrically have a connection pair of a plunger and a counterpart receiving this, which engages each other axially non-displaceable, the plunger and its counterpart are axially positioned with respect to their position in such a way that in the case of said further screwing on the second screw cap on the central neck up to its Anschlagschraubstellung the container contents for a flow to the second screw cap and the pouring and / or drinking opening is released, by means of which in this further screwing on the Closing foil too while displacing the seal between it and the cap-releasing intermediate piston, wherein the captured by the intermediate piston receiving sleeve pierces the sealing foil with its at least one knife edge, and that
• f) when screwing the second screw in the opposite direction and thus back to its initial screw the intermediate piston is again brought to the sealing engagement with the first screw, such that the passage to the second screw and its pouring is interrupted again.

Of the Neck of the container can first be hermetically sealed by means of a sealing foil which is attached to a circular sealing surface the edge of the neck was sealed and the relocation the second screw cap in the Anschlagschraubstellung like the Closing foil from the at least one knife edge to the receiving sleeve to break through is.

From It is particularly advantageous if the external thread of the central nozzle forms a coarse thread with the thread of the second screw cap, thus, that each less than a revolution of the second screw cap required is to open in one direction of rotation of the container and in the other direction of rotation bring about a closing of the same. This makes it easier for the user to place the container or bottle in one Hand and hold with the thumb and forefinger of this hand that open and closing to effect the second screw cap.

there has it proven the plunger on the inside of the lid the second screw cap and a counterpart forming sleeve on the opposite Side of the receptacle to arrange.

According to one preferred embodiment the ram rotatable but axially immovable, latched into the sleeve. It understands However, if necessary between the plunger and the sleeve can also be provided with a suitable thread pairing, when screwing the second screw cap to the displacement line the sleeve opposite the first screw cap contributes.

on the other hand if necessary, it can also be enough that the Pestle and the sleeve have an interference fit together. Is however one Thread pairing provided, then a left-hand thread pairing is preferred.

Advantageous has the receptacle a coaxial rod lug forming the sleeve as a counterpart, and the outer circumference of the rod approach puts at its root with a diameter corresponding coaxial passage opening in the transverse wall of first screw cap is the coaxial guide, which in the initial screw the second screw a further seal between the receiving sleeve and the first screw cap forms.

At the top of the reception box and at the bottom of the first screw cap can or can be advantageous one or more further seals (s) may be provided, each one have the shape of a ring seal.

there For example, the first passage may be provided in a retainer ring for the receptacle his, the receiving box surrounds and is connected to this by the flexible apron, the one Relative movement between the axially displaceable receiving sleeve and the retaining ring allowed on the inner circumference of the first screw cap stationary is fastened.

Further can be attached to one of the sealing film, if present, facing edge of the Halterings the sealing film for inclusion of zuzumischenden Component in the receiving box sealed and in said displacement of the receiving sleeve by means further screwing the second screw cap on the center Necks up to the stop screwing position if necessary together with the sealing foil be severable from the knife edge.

In dependence from the respective axial distance between the closure film and Sealing film can also close the sealing film just before the sealing film be severable.

there can another passage from the circumference of the rod approach the Sleeve (of the counterpart) formed in spaced axial notches be that only then in the field of coaxial guidance and thus for mating with the wall of the coaxial passage opening in get the first screw when the second screw cap during Unscrew its stop screw position approaches.

Appropriately points the first screw cap above it for screwing onto the external thread of the neck of the container certain internal thread a circumferential flexible sealing lip Plant on the edge of the initial still through the sealed film sealed neck.

It is preferred, the knife edge at least over part of its circumference toothed train.

It has proven to be advantageous to Hal tering in a provided on the inner circumference of the first screw cap and a part of her forming, to attach to the container open can, which is elastically expandable when inserting the retaining ring and has a catch for its inclusion.

there can then the sealing lip on the container facing the free edge the rifle trained be and besides when screwing the first screw cap on the container for the purpose of remaining at this edge expandable and then between the edge and the Wall of the first screw cap be clamped.

It is appropriate that the second Screw cap has an inner collar, after screwing the second screw cap on the first screw cap within their central nozzle remains and on its outside at least one circumferential Sealing lip for sealing against the Inner wall of the central nozzle has. This ensures that that the container capacity not after entering the pouring opening partly also laterally past the second screw cap in the Free could kick.

It is preferred that the second screw cap and the central neck a left-hand thread pairing exhibit.
