Description

DESCRIPTION

Push-pull closure for a container

The invention relates to a push-pull closure for a package according to the preamble of claim 1. A closure cap with a movable telescopic part, wherein the telescopic part is known from publication DE 10 2004 055 338 A1 It is guided movable on an outlet fitting. Liquid can be drawn from the closing cap through corresponding holes in the telescopic part. Through a downward pressure of the telescopic part, the closing cap is closed again.

Utility model publication DE 202007017383 U1 publishes a closure of a beverage bottle, in which a nozzle is provided, which is linearly movable, for example, with the user's teeth from a closed position to an open position.

It is also known from the publication of utility model 202008002717 U1 also a closure cap for a beverage container, in which there is a functional section, which linearly opens and closes a passage of liquid in the closure cap. Here too this is solved through the lifting of a closing piece and the downward pressure of it.

Publication DE 102012002935 A1 publishes a push-pull closure for a beverage container, in which a lockable passage hole is also provided here, in which a guided pivot can be raised and lowered in this hole and in this way Open or close the hole.

Publication US 5810 185 A again presents a closure cap, whose linearly mobile closure element can be screwed into an open position and remains in the closure during the extraction of a liquid. The closing cap does not rise here from the closure, but only threads, so that the guide on a thread ensures that the closure cannot be pressed in the case of carbonated beverages or, for example, the carbonic tree inadvertently and in this way the drink becomes tasteless.

These solutions known in the state of the art have in common that a linear opening and closing of a bottle type container is achieved through the lifting and downward pressure of a linearly guided closing body, which is part of the cap of closing itself and is guided in it. This can be done manually or also, for example, with the help of the teeth, which grip the movable closing body and raise and lower them. This is an example of its functionality, which often finds application in the field of sport. In addition, the known solutions have in common that the closing caps are only covered by a seal placed above or a plastic cap, which no longer has any utility after opening, since the bottle is opened or closed by means of the thrust-pull mechanics. In general, other coverage of this closure cap is no longer necessary. It is only possible to place a plastic cap, which has no importance for functionality.

Publication WO 2014/037825 A1 refers to a spout with a tubular body for insertion into a container, wherein a spout nozzle is housed within the tubular body in a displaceable manner relative to the tubular body between a retracted position and a position extended. The pouring nozzle is raised in this case during unscrewing of the closing cap through coupling means outside the closed position, for which purpose a coupling element is fixed on the inner side in the closing cap.

A similar solution is published in publication FR 2799739 A1 in which a spout nozzle is also published in a tubular body for insertion into a container, especially a bottleneck. The pouring nozzle has deformable sections here, which make it possible to lift the pouring nozzle through the unscrewing of a closing cap out of the closed position. Also here the pouring nozzle is raised during unscrewing of the closing cap through coupling means outside the closed position, which are inserted on the inner side in the closing cap and establish a removable positive connection connection with the upper end of the pouring nozzle, until the cap is completely unscrewed.

FR 2875485 A1 shows another solution of this type, in which a pouring nozzle is raised during unscrewing of the closing cap through coupling means from the closed position, which is inserted on the inner side into the cap of closing. Also here a positive removable connection is established with the upper end of the pouring nozzle until the closing cap is completely unscrewed, fitting here a projection placed on the inner side of the closing cap on the closing nozzle.

Given this background, the purpose of the present invention is to create a combination of a threaded closure and a push-pull closure, where the metered extraction of liquids from the container is especially intended. In this case, the closing cap must establish a mechanical connection with the mobile closing element of the push-pull pivot type, which is released during the opening and is established again during the closing of the closing cap, so that with the unscrewing of the closing cap the mobile closing element of the pivot type of the push-pull closure is raised linearly already in the opening position and during the screwing of the closing cap the closing element is pressed Pivot type of the push-pull lock back to the closed position. Faced with the prior art, this must be achieved without coupling elements, which are inserted in the closure cap for connection with the closure element.

This is solved according to the invention by means of a push-pull closure with the features of claim 1.

The other claims are directed to advantageous configurations of the invention.

According to the invention, the task is solved by means of a push-pull closure for a container, which is composed of a base insert, on the one hand, which is inserted in the hole of the container, for example of a bottle and by a guided closure body in this base insert, which is transferable through an upward and downward movement from a lower closed position to a high closed position. This is known in the state of the art.

The invention consists in that the movable closing body of the push-pull closure establishes a removable connection with a screw-on cap on the package. This closure cap is more conveniently a metal cap, known for a long time in the state of the art, in the form of an aluminum-MCA closure, which is guided on an external thread, for example a bottleneck .

The closing body of the push-pull closure establishes a removable connection with this closing cap, so that during the unscrewing of the closing cap the closing body is raised from its closed position until it reaches an upper point of the open position and is retained here in the base insert. To this end, the base insert has a kind of stop for the movable closing body, so that the closing body cannot be raised beyond this closed position outside the base insert.

The closing cap, however, is unscrewed further when the open position of the closing body is reached, that is to say that it has not yet reached its highest point in the outer thread of the body and is unscrewed even beyond the position Open closing body. In this way, it is achieved that the closure cap is detached from the closure body, causing the use of the threaded joint between the closure cap and the container a definite release of this connection, which is achieved by saving strength through the user, since, in effect, the release is supported through the rotary movement and the upward movement of the closing cap made at the same time.

The inventive application of the area of connection between the closure cap and the closure body of the thrust closure is achieved through a rib of the type of surrounding annular cord in the closure cap, in which the closure body fits with mooring effect This rib is arranged according to the invention in the transition zone from the upper closing level to the surrounding side wall of the closing hatch, so that the closing body can fit on its upper side in this rib and can be connected in this case removable with the hood.

To this end, the closure body has a disc-shaped upper connecting plate, which fits into the rib and is thus detachably connected with the closing cap, so that the disk-shaped union plate of the closure body rests superficially on the inner surface of the closure level.

This allows that in the case of a usual metal closure in the aluminum market, it can be adapted in a usual way during the sealing and closing of the container already to the thread and also the push-pull closure. Alternatively, a deformation can be performed or the thread can also be adapted only by means of a tool corresponding to the thread of the package.

Through the detachment of the closure cap and the closure body, the closure cap can now be removed from the closure body and the container itself and remains as a separate body, which does not prevent the extraction of a liquid from the container. The closing body is in its upper extraction position, whereby liquid can be immediately withdrawn from the push-pull closure through the overturning of the container.

When the push-pull closure or the container is closed, an inverse sequence is performed. The closing cap is now placed again on the outer thread of the container and in this case overlaps the closing body, which is always still raised in its opening position. The closing cap is now screwed onto the thread of so that after a few turns it hits the closing body and moves it through the downward movement during the curl of the closing cap at the same time down to its closed position. Also here again at the end of this downward movement of the closing body arrives at the base insert, as soon as the closing body is fully inserted into the base insert.

The closing cap, however, can be screwed a little further here on the thread, so that an establishment of the removable joint between the closing body and the closing cap is again achieved, so that also Here this union is supported through the thread and the downward movement of the closing cap and in this way it is performed automatically without much expense of force through the user. As soon as the closure cap is fully screwed onto the container, the closure body has also been brought back to its removable joint position with the closure cap.

In this way, it is achieved with advantage that the lifting of the closing body from a closed position to an open position is carried out without the intervention of the user only through unscrewing of the closing cap. This has especially great hygienic advantages. If special applications of such closure are considered, for example, in the field of food oil and vinegar or other denser liquids, it can easily be recognized that manual lifting of a closure body from a thrust closure is not possible. traction without transmission of germs on this closure.

Nor is an elevation necessary here as in the sports field normally with teeth. The application of this closure is mainly directed to dosable liquids, such as vinegar, oil, spirits, alcoholic beverages and the like, in which a selective extraction of small quantities is also intended, as opposed to a usual push-pull closure, as provided, for example, in bottles of mineral water drinks and juices, in which a large quantity of liquid should be extracted as quickly as possible.

In this case, the base insert has sealed projections on its outer surface, pointing towards the wall of the opening of the container, for example towards an inside of the bottle body, which are supported during the insertion of the base insert , for example, in the neck of the bottle internally fixed in the body of the bottle and in this way they have a sealing action as well as fixing.

Towards the upper edge of the opening of the container, the base insert has a surrounding support ring angled at a right angle, which sits on the opening of the container and thus fixes the insert, with respect to its insertion depth in The opening of the container.

The guided closure body in the base insert has at least one guide projection on the inner side, which is conducted along at least one inner guide ring of the base insert and rests on them, so that the guide ring forms a stop for the guide arm and thus limits the linear displacement capacity of the closure body in the base insert.

The closing body is guided in this case during the insertion in the base insert to the upper edge of the base insert to provide a tight seal of the push-pull closure. During opening of the push-pull closure, the closing body is moved linearly from this position and raised, so that the guide projection is supported by a surrounding edge disposed on the inner side of the lower guide ring of the insert of base and thus limits the fierce extraction of the base insert. In this case, an open annular space results between the closure body and the base insert, from which the liquid that is, for example, in a bottle can exit.

This represents a clear distinction with respect to the push-pull closures of the prior art, since the push-pull closure of the invention gives much more importance to the aspect of the dosage, since the liquid can only leave radially from the annular space and in this way cannot be removed in the center in the longitudinal direction of the neck of the bottle outside the closing cap or the movable closing body itself, as is the case, for example, in water bottles mineral or sports drink bottles. Therefore, here the area of application in this closure is also directed more strongly to liquids, which are used in dosages, for example oil, vinegar or also alcoholic beverages.

The specific configuration features of the push-pull closure according to the invention in different alternatives are described in detail below with the help of the drawings.

Shows:

Figure 1 shows the push-pull closure 1 with closing body 3 lowered and closing cap 5 placed on top.

Figure 2 shows the closing body 3 raised from the closed position to the open position with the cap closing 5 always placed on top.

Figure 3 shows the closing cap 5 now raised with the push-pull closure 1 open.

Figure 4 shows an exploded orderly drawing of the push-pull closure 1 according to the invention with closure cap 5 and sealing body 21.

Figure 5 shows a construction variant with sealing body 21 in the closed position.

Figure 6 shows a constructive variant with sealing body 21, raised closing body 3 and closing cap 5 placed on top as well as

Figure 7 shows the construction variant with a sealing body 21 with an inclined pouring representation and with a closing body 3 in the open position.

Figures 1 to 3 show all the constructive elements of the push-pull closure 1 according to the invention with cap 5 placed above in the closed position. In this case, the closing cap is completely screwed onto the container 4, in this case a bottleneck. In the opening the base insert 2 is inserted, in which the closing body 3 is linearly movable.

Pointing downwards from the closing body 3, a first and second guide projections 11 and 16 are arranged, which collaborate with the base insert 2. The base insert 2 has for this purpose a guide ring 10, which collaborates with the first guide projection 11 of the closing body 3. The guide projection 11 is guided in this case within the guide ring 10 and in this way aligns a linear vertical guide of the closing body 3 inside the closing ring 10. Other function is a limitation of the guide of the closing body 3 in the base insert 2, in which in the lower edge 13 of the first guide projection 11 there is arranged a edge 12 pointing towards the guide ring 10, so that when the open position of the closing body 3 is reached, as can be recognized, for example, in figures 2 and 3, this edge 12 is supported by the lower edge 13 of the guide ring 10.

In addition to the first guide projection 11, a second guide projection 16 is displaced outwardly on the lower side of the closure cap 5, which rests on the side wall 14 of the base insert 2 and is vertically movable therein. This second guide projection 16 seals the push-pull closure 1, on the one hand, in the closed position together with the side wall 14 of the base insert 2.

In the open position, recognizable in Figures 2 and 3, of the push-pull closure, this guide projection 16 is raised to the point where an annular gap 19 is released between the bottom edge 13 of the second guide projection 16 and from the upper edge of the base insert, through which the liquid contained in the container 4 can escape. The removable connection between the closing body 3 and the closing cap 5 is carried out, as can be seen in Figures 1 and 2, below the closure level 6 of the closure cap 5 within a rib 8 of the annular cord type, which extends around the area of the closure cap 5 below the closure level 6. In this rib 8 of the type of annular cord fits the closure body 3 with a connecting plate 9 that delimits the closure body on the upper side, so that this closure plate 9 fits into the rib 8 of the type of annular cord. In this case, the disk-shaped junction plate 9 rests on the lower side of the closing level 6 of the closing cap 5.

In Figures 1 to 3 it can be recognized that in the closed position of Figure 1, the connecting plate 9 of the closing body 3 fits into the rib 8 of the annular cord type of the closing cap 5 and, as can be recognizing in figure 2, by unscrewing the closing cap 5 the closing body 3 is raised at the same time in this way, in this case, the closing body 3 can be rotated at the same time, since it is housed rotating on guide ring 10 of base insert 2.

If the opening position of Fig. 2 is reached, the support of the edge 12 of the closing body 3 is produced in the lower edge 13 of the guide ring 10 of the base insert 2. In this way, the upward movement from the base insert 2 of the closing body 3. The closing body 3 cannot be lifted further from the base insert 2. But since the closing cap 5 in this position is not yet fully unscrewed from the container 4 and its external thread, through the next screw-in movement of the cap a separation occurs in the area of the rib 8 of the annular cord type, since the connecting plate 9 is now tied in its position, but the closing cap 5 it is removed more vertically from the container 4.

The closure cap 5 now released in the area of the removable joints can be completely removed out of the container 4 after the complete unscrewing of the outer thread of the container 4, so that during the unscrewing process it has completely raised the closure body 3 to the open position of the push-pull closure 1. In this way, it can be poured by dumping the container 4 directly after unscrewing of the closing cap 5. It is not necessary to manually raise the push-pull closure 1 or the closure body 3 of the push-pull closure 1 to the open position. In this way, a contact of the closure body 3 is avoided according to the invention.

During the screwing of the closure 1 the reverse sequence is carried out, as already described, so that the closure cap 5 can now be screwed in without having to initiate a removable connection with the closure body 3 of the push-pull closure until the closing level 6 or the lower edge 13 of the rib 8 of the annular cord type abuts the joint plate 9 of the closing body 3 and now through the next screwing of the closing cap 5 moves the closing body 3 returns to its closed position in the base insert 2.

If the closing body has reached its lowest point in the base insert 2 and, therefore, of its closed position, another vertical downward movement of the closing body 3 in the base insert 2 is no longer possible. the connection plate 9 is again pressed into the rib 8 of the corresponding annular bead type 5 in the next screw-in of the closing cap 5 and is fastened here to be raised again with a new screw-in .

As can be seen in the figures, the guide ring 10 of the base insert 2 is disposed away from the side wall 14 of the base insert 2, resulting in an annular space 15 between these components. This annular space 15 serves for the extraction of liquid as soon as the closing body 3 is in the open position. Through this annular space 15, liquid can be conducted towards the closing body 3, the closing body 3 having the position in the upper open position of its second guide projection 16 a position distanced from the side wall 14 and resulting from this way an annular gap 19, through which liquid can escape.

According to the invention, the first guide projection 11, which is guided in the guide ring 10 of the base insert 2, can be configured as a cylindrical body or can be formed by a circular arrangement of several guide arms. As shown in the figures, this guide projection 11 is constituted both by a cylindrical section, which extends under the guide plate 9 and by circularly arranged guide arms supported by this cylindrical section, which end at the edges 12. In this way, it is achieved that the first guide projection 11 is elastically deformable in its lower section, so that it can be more easily inserted into the guide ring 10 of the base insert 2 during the first assembly of the push-pull closure, so that the guide arms of the first guide projection 11 are elastically resting on the guide ring 10.

In the constructive solution represented by the invention, the second guide projection 16 has a recess 23 in its lower edge 13, which serves to form the annular gap 19. This recess is arranged in the lower edge of the second guide projection 16 pointing towards the side wall 14 of the base insert 2. Through the corresponding shaping of the recess a defined annular gap is generated to generate a size of the annular gap adapted to the liquid used.

In this case, it is applied that the formation of the annular interstitium can be configured more or less according to the viscosity of the liquid to be accommodated to enable a defined discharge. The construction form of the invention represented in the figures presents in the base insert 2 in its upper area an outer surrounding support ring 17 approximately at right angles to the side wall 14, with which the base insert 2 rests on the upper edge 18 of the opening of the container 4. The reason is that in this way the insertion depth of the insert 2 in the container 4 can be established, thereby also the pouring height on the upper edge of the base insert 2.

In addition to the adaptation of the second guide projection 16 through a recess for the definition of the spill through the push-pull closure 1, the upper edge 20 of the base insert is formed in the solution represented supporting the spill. In this case, a widening of the upper edge 20 of the base insert is provided rounded, so that a good movement of liquid flow from this gap 19 is formed and a contaminated discharge from the thrust closure can be avoided. traction 1.

Finally, a variant of the push-pull closure is also shown in the drawing of Figures 5 to 7, in which an additional sealing body is used. This is configured in the drawing representation as a spherical sealing body 21, which is supported by a corresponding circular round sealing housing 22 on the lower side of the base insert 2.

In figure 5 a push-pull closure 1 is shown which is in the closed position, in which the sealing body 21 is seated in the housing of the sealing body 22. This is achieved through a clamping pressure. of the sealing body 21 through the first guide projection 11 of the closing body 3. In the downward position of the closing body 3, in this case the first guide projection 11 presses the sealing body 21 in its housing sealing body 22.

In figure 6 below we see the closing body 3 which is in the open position, which is now raised from the sealing body 21 in its upper position. In this way, the sealing body 21 is released on the upper side to move with a corresponding inclination outside the housing of the sealing body 22.

Finally, in the last figure 7 it is possible to recognize how the sealing body 21 moves during a tipping movement of the container 4 from its sealing position in the housing of the sealing body 22 towards the first guide projection 11 and of this the housing of the sealing body 22 is released through this housing of the open sealing body 22, the liquid in the container 4 can now circulate to the base insert 2 to be extracted through the annular space 15 and the annular interstitium 19 extending over outside the push-pull closure 1.

In this way the additional sealing body 21 here mainly provides an additional sealing action, for example in especially volatile liquids, in which an additional sealing is intended within the framework of the push-pull closure 1.
