EP0624526A2 - Closure for container with liquid or pasty contents - Google Patents

Abstract

Closures are known, which only permit the contents of the container to be squeezed out in an unsatisfactory manner and are furthermore of relatively complex design and therefore expensive to manufacture. The object of the invention, in addition to cost-effective manufacture, is also to permit the contents to be squeezed out of the container in an optimum manner. For this purpose, provision is made for the lid part (5) to consist of a material of high elasticity and to be firmly connected to a supporting body (4) which is formed from a material of less elasticity and is otherwise joined to the neck of the bottle (1) or to the closure (2). <IMAGE>

Description

The present invention relates to a closure for containers with liquid or pasty content according to the preambles of claims 1, 5 and 8.

A closure according to the preamble of claim 1 is known for example from EP-A-O 392 208.

With the closure shown therein, it is possible to open or close the container, for example a bottle or tube made of an elastic material, solely by being compressed or subsequently deformed when the handle is loosened, without the closure itself being actuated must become.

Naturally, this handling offers considerable handling advantages over the closures known hitherto.
In this respect, this invention has proven itself.

However, the implementation of this known concept poses some problems, especially since such closures are mass-produced items that must be correspondingly inexpensive to manufacture in order to find market acceptance.
The known closure mentioned does not sufficiently meet this requirement.

In this sense, one of the documents CH-A-229 106, CH-A-267 023, FR-A 1 427 649 and US-A 3 754 690 see known closure which corresponds to the preamble of claim 5.

According to this prior art, a valve body or cover is also arranged in the closure, which is generally circularly limited, which is guided in a movable manner and lifts off its seat when the contents of the container are pressed. Here, the valve cover or body is flowed around on all sides by the container contents, so that essentially a hose forms when the container contents emerge from the opened closure. Since the interior of the hose, with its diameter corresponding to the diameter of the valve body, must be filled with air, the hose tears open directly at the trailing edge, so that air can enter the interior of the container there. In practice, however, the hose collapses after being torn open, since the contents of the container are discharged unevenly over the circumference of the annular outlet opening, so that the strand of material discharged from the container has an extremely uneven mass cross section, and also an uneven shape.
The result of this is that it is not clear how much of the container content has been dispensed, nor is there any possibility of achieving a uniform shape for the strand of material being dispensed.

Problems also arise when closing the closure after being pressed out, when the pressure on the container content is released, in the case of the forms of training according to the prior art, because the valve plate or body, which is based on its seat, presses the container contents surrounding it out of the opening and outwards This smears the edge of the outlet opening so that it is necessary in any case to clean or wipe this area. This is associated with material loss and can only be carried out with additional handling. Such automatic container closures, which have been known for a long time, have therefore not been able to establish themselves in practice, or only to an extremely limited extent.

A closure according to the preamble of claim 8 is known from US-A 2 028 843 and from EP-A 0 392 208 already mentioned.

In both known embodiments, the closure is provided with a single lid or a flap which is under spring action and is thus kept closed. The content pressed out of the container against the force of this locking spring leaves the container in a compact strand. However, it can be deflected laterally under the action of the spring-loaded flap, which may be undesirable.
If it is a liquid in the container contents, there may be the possibility that this is widely distributed or even divided under the flap or lid effect, which is undesirable in certain cases.

The present invention is therefore based on the object of designing a closure in such a way that its functionality is fully preserved over the entire period of use, that the contents of the container in a compact strand or jet can be metered very finely depending on the pressure exerted on the container and that the closure is inexpensive to manufacture.

This object is achieved by a closure which has the features of claims 1, 5 or 8.

The construction of the closure, which is basically very simple, has the advantage, first of all, that it can be manufactured very inexpensively, since the cover part can also be formed as an injection molded part, like the supporting body to which the cover part is advantageously molded .

The advantages known in the case of plastic injection molded parts with regard to their manufacture thus come to full effect in the formation of this closure.

In addition to the undoubted economic advantage, another advantage of this closure can be seen in the fact that the cover part is very robust and is practically not subject to wear and that operational wear and tear can be excluded, so that there is an overall service life that is far above the service life of the container .

According to an advantageous embodiment of the closure according to claim 1, it is provided that the cover part encloses at least one wing of the supporting body which is movable about a pivot axis, this wing giving the cover part the necessary stability to ensure a reproducible open and / or. To enable the closed position of the cover part.
The wing is advantageously connected to the pivot axis of the carrier body by means of a film hinge, since the material of the carrier body has a low elasticity according to the invention, so that a perfect pivoting movement is possible.
To support the closing movement of the cover part, at least one pull rib extending approximately in the closing direction is formed on the cover part, which pulls the pivoted cover part into a closed position due to its elastic forces, in which it lies sealingly.

It has been found to be particularly advantageous as the material with high elasticity from which the cover part is made, Santoprene (registered trademark) or another suitable thermoplastic material, this material having an excellent sealing effect in the event that it is in the sense of a sealing lip is pressed against an opening edge. The low elasticity material from which the support body is made is preferably made of polyurethane or polypropylene. These plastics have the inherent rigidity necessary for the function of the supporting body.

In the formation of the closure according to the features of claim 5, the container contents, before it reaches the opening of the nozzle, is guided around the filler piece within the nozzle, so that no possibility there is that the container content is tubular. After passing the filler piece, no air can enter the space downstream of the filler piece, since the container contents are completely enclosed by the nozzle. On the contrary, the nozzle again directs the contents of the container flowing around the filler together to a smaller flow cross section, so that it results in a compact and uniformly shaped strand before it emerges from the nozzle opening. This strand of material discharged from the nozzle opening is therefore clear, very good and easy to dose and can also be placed exactly when it is desired that it occupies a certain predetermined space.
When closing the closure, i.e. pushing the movable nozzle back onto the filler, the material strand that has escaped - after the pressure on the container contents has dropped to open the closure - is cut off in a defined manner and thus portioned exactly, without the risk that due to the closing process in Remnants of material are deposited or remain stuck in the vicinity of the opening, which cause contamination or even obstruction of the functionality of the closure.
When closing, i.e. when moving the displaceable nozzle relative to the stuck filler piece, the last quantities of material immediately in front of the filler piece are ejected from the nozzle in a manner similar to that of a piston, without touching or reaching the outer edges or areas of the nozzle. So there is a very clean conclusion.

According to an advantageous embodiment, the displaceable nozzle is designed as a tube section, with a recess or narrowing of the diameter arranged at the outer end, into which the preferably conical outer end of the fixed filling piece fits in a sealing manner.

This design substantially improves the flow around the filler piece when it is squeezed out, the material content is forced downstream into a narrower flow cross section downstream of the filler piece guided so that a compact closed strand of material is fed to the nozzle outlet and exits from it.

Due to the arrangement of opposite flaps as it has a closure according to claim 8, it is also achieved that the contents of the container emerge from the middle of the closure when squeezed out, in a compact coherent strand, since the more or less open opposite flaps are inclined guide surfaces form, which merge the expressed container content into a strand. A precisely refined and therefore also meterable strand is therefore dispensed from the container at each opening point. Furthermore, it is ensured due to the opposite arrangement of the flaps that when the pressure on the container is closed, the flaps close together and evenly, cut off the strand cleanly and press remnants of the expressed container contents back into the container, so that residues of the container contents are avoided after the closure can get stuck on the outside of the closure and there, for example due to hardening, are the cause of later malfunctions.

According to an advantageous development of the closure according to claim 8, a beam-shaped support is arranged below the common closing joint of the two flaps, the side of this support directed towards the inside of the container being advantageously designed in a cutting shape.
This support ensures good retention of the opposite flaps in the closed state and thus also a good closure of the container contents. On the other hand, this bar-shaped support is only relatively narrow, although it causes a division of the expressed strand at the point at which it is arranged, this division of the expressed strand is immediately reversed again due to the inclined position of the two opposite flaps, which the expressed Compress the strand above this beam-shaped support again, so that a uniform, compact strand emerges between the two opened limits of the flaps. The cutting-like design of the beam-shaped support directed towards the inside of the container acts aerodynamically on the strand during the squeezing process, so that there is an even distribution of the strand on both sides and thus neither of the two oppositely arranged flaps is opened further during the squeezing process, so that a deviation of the strand from a straight squeezing direction would result.

Under the flaps arms extending into the container neck are advantageously arranged, the free ends of which are connected to a spring, which in turn is stuck to the container neck. These arms are expediently provided with widenings under the two sides of the flaps. With this arrangement, an exact guidance of the flaps is achieved during the opening and closing process against the action of the closing spring, so that the closing spring cooperates optimally with the flaps in every open position and in particular in the closed position. Furthermore, the widening of the arms arranged on the two sides of the flaps effectively prevents parts of the container contents from flowing around the flaps when the flaps are opened - practically only the slot that opens between the two flaps becomes narrower or wider for shaping of the strand emerging from the closure used.

Further advantageous embodiments of the inventions are characterized in the subclaims.

Embodiments of the inventions are described below with reference to the accompanying drawings.

A bottle 1 made of an elastic material and shown in FIGS. 1 to 4 is closed in the region of its bottle neck with a closure 2 which can be screwed onto the bottle neck 13 by means of a molded screw part 3.

The closure 2, which, like the bottle 1 in the present exemplary embodiments, is designed as a cylindrical body, is provided in its area partially covering the bottle neck 13 with a cover part 5 which is firmly connected to a support body 4.

The support body 4 consists of a support body jacket 12, which is supported on the bottle neck 13 with a circumferential attachment 14.
In its upper end region facing away from the bottle neck 13, the supporting body jacket is formed on the inside as a sealing surface 15, while, as FIG. 4 shows very clearly, one in the middle region Pivot axis 7 extends from one side of the inner wall of the support body shell 12 to the other side.

According to the embodiment of FIGS. 1 and 2, wings 6 are connected on both sides to this pivot axis 7, the connection between the wings 6 and the pivot axis being effected via a film hinge 8, so that a smooth pivoting movement of the wings 6 is possible.

The entire support body 4, that is, both the support body jacket 12 and the pivot axis 7 and the wings 6 are made of a material, preferably a plastic, with low elasticity.

The pivot axis 7 and the wings 6 are encased by the cover part 5, which consists of a material of high elasticity.
Here, an intimate bond between the wings 6 and the cover part 5 is achieved in that openings 11 in the wings 6 are filled with the material of the cover part 5, so that there is practically a positive connection.
The outer edge of the cover part 5, which faces the supporting body jacket 12, is designed as a sealing lip 10 which, in the closed position, lies sealingly against the sealing surface 15 of the supporting body jacket 12.

In order to ensure smooth pivoting into an open position of the cover part 5, this is provided with a kink groove 9 extending in the direction of the pivot axis 7.
On the underside facing the bottle neck 13, extending approximately in the closing direction, the lid part 5 is provided in the area of each wing 6 with a pull rib 17 which, due to its elastic forces, pulls the sealing area of the lid part 5 into a closed position for closing.

While the embodiment shown in FIGS. 1 and 2 represents a support body 4 which has two wings 6, so that the cover part 3 is an embodiment variant in which the cover part can only be opened on one side, with only one pivotable wing being provided for this purpose, while the other side is one with the supporting body jacket 12 firmly connected collar 16 is formed.

The lid part is opened by squeezing the bottle 1, the bottle contents being pressed against the underside of the lid part 5, and the lid part 5 is thus practically weighed out by the applied pressure force.
After this squeezing has ended, ie when there is no longer any pressing pressure on the cover part 5, it is returned to a closed position by the material-related elastic forces. In the closed position, the sealing lip 10 nestles against the sealing surface 1 so that the inside of the bottle is largely protected.

A shown in FIGS. 6 to 11, also designed as a bottle container 21 for liquid or pasty content is provided with a neck 22, on the outer surface of a screw thread 3 for a cap or the like. is arranged. By means of an internally threaded cap 24, which is screwed onto the container neck 22, a closure cap 25 with an inner end, which is designed as an outwardly standing annular flange 26, optionally with the interposition of a seal 27, against the upper edge 28 of the container neck 22 captured. The cap 25 continues the container neck 22 to a certain extent.

In the area of the flange 26 and the seal 27 of the closure cap 25, a holder 29 for a centrally arranged filler piece 30 is formed and fastened. This holder 29 consists of an outer ring 31, from which individual spokes protrude inwards, on which the filler piece 30, projecting upwards, is stuck. This whole arrangement can be molded in one piece from plastic.

The filler 30 is designed as a cylindrical body in its The uppermost region projects beyond a central opening in the closure cap 25 and is expediently designed there as a cone 33 with a diameter constriction.

Within the cap 25, a nozzle 34 is slidably guided. This nozzle 34 consists of a tube section which is provided at its inner end with an outwardly extending flange 35. This flange 35 lies with its outer surface on the inner surface of the cap 25 and serves as a guide for the nozzle 34. Furthermore, an inwardly directed flange 36 is formed on the cap 25 at the outer end, which with its inner surface against the outer surface of the tubular part the nozzle 34 abuts and this also leads. In the cavity formed between the two flanges 35 and 36 with an annular cross section, a compression spring 37 is arranged, which is designed as a helical spring, on the one hand abuts against the flange 36 and on the other hand against the flange 35. This compression spring 37 holds the nozzle 34 in the closed position shown in FIG. 6.

This nozzle is formed at its outer end as a hollow cone 38 with a central opening 39. Between the inner surface of the hollow cone 38 and the flat outer surface of the cone-shaped formation 33 in the outer end of the filler 30, a solid and tight closure forms in the closed state of the nozzle . The free inside diameter of the nozzle 34 is substantially larger than the outside diameter of the filling piece 30, so that a further free space is created within the nozzle 34 which surrounds the filling piece 30.

The compression spring 37 is designed in terms of its spring characteristics such that it holds the nozzle 34 with a tight seal against the filler 10, but yields when the contents of the container 21 are pressed, so that the nozzle 34 is guided within the opposite of the stuck filler 30 Closure cap 25 is displaced outwards by means of the flanges 35 and 36 and thus releases the nozzle opening 39, so that the position corresponding to FIG. 7 is reached. The contents of the container flow then around the filler 30, within the space between the filler and the nozzle to the opening 39. Due to the conically contracted shape 38 of the nozzle 34, which now lies above the upper conical end 33 of the filler 30, the expressed container content is compressed in this area and formed into a compact strand before it can exit the nozzle opening 39. Depending on the strength of the pressure on the container content, the spring 37 is more or less compressed and thus the distance of the nozzle opening 39 is removed from the outer end 33 of the filler piece 30, so that the passage cross section between the upper nozzle end and the filler piece is increased or decreased and accordingly, a larger or smaller amount of the container contents can pass between the outer end 33 of the filler 30 and the outer end of the nozzle 34, which is designed as a hollow cone 38, to the nozzle opening 39, in order to emerge there as a compact, uniformly shaped strand.

In order to effectively prevent the closure from opening when not in use, during transport and storage, a closure cover 40 is provided which engages over the upper end of the closure cap 25 and is clipped on or screwed on there. The closure cover 30 lies with its inner surface firmly against the outer surface of the nozzle 34 and the filler piece 30, so that the nozzle 34 cannot be lifted off the filler piece 30 and thus open the opening 39.

Another exemplary embodiment is shown in FIGS. 8 to 10, the same reference numerals being used for the same parts. According to this embodiment, the holder ring 31 for the filler 30 is provided with a holder 41 for the bar or leaf spring 42, which is shaped in the form of a W and protrudes into the neck 22 of the container 21. The nozzle 34 is provided with lugs 43 which protrude below the filler 30 into the container neck 22 and at its end engage under a crest 45 of the inner angle 46 of the W-shaped spring 42 with a transverse connecting piece 44. The outer long legs 47 of the W-shaped spring run approximately parallel in the closed state of the closure to the wall of the container neck 2, as can be seen from FIG. 8. The W-shaped spring 22 is slightly tensioned in this state in order to keep the closure closed. When the contents of the container are pressed, the W-shaped spring yields and the state corresponding to FIG. 9 is established. The nozzle 34 is displaced outward in its guide 35, 36 with respect to the filler 30 and opens the opening 39, the spring 42 being tensioned more by bending its long legs 47 and its inner angle 46. When the pressure on the container content decreases, the spring 42 pulls the nozzle 34 back against the filler until the opening 39 is closed. All other functions correspond to the description given above in connection with the exemplary embodiment according to FIGS. 6 and 7.

FIG. 11 shows a greatly enlarged partial section of FIG. 6 or 8. Between the flange 35 at the inner end of the nozzle 34 and its counter surface, the guide surface on the inside of the closure cap 25, a sealing lip 49 is formed on the outside of the flange. This prevents the contents of the container from getting into the nozzle guide and thus impairing the nozzle movement.

The closure according to the invention is designed in particular with regard to the arrangement of the spring such that it forms a coherent unit. On the one hand, it is therefore easy to manufacture, on the other hand, in a considerably advantageous manner compared to the previously known closures, it is easy to assemble or can be retrofitted or exchanged on any container with a standardized screw neck without any changes or special interventions on the container.

In the exemplary embodiment shown in FIGS. 12 to 14, a lid 53 is placed on the neck 51 of the container 52, which is seated on the upper edge of the neck 51 with an annular flange 54 projecting outwards, possibly with an intermediate layer in the form of a seal . The cover 53 is held in place by a cap 55, which has a screw thread 56 is screwed onto the thread arranged on the outside of the neck 51, the cap 55 being provided with an inwardly projecting circular projection 57 which overlaps the flange 54. By screwing on the cap 55, the lid 53 can be securely and securely attached to the neck 51 of the container 52.

This entire arrangement can be used instead of a conventional screw cap closing the container and can be exchanged for this screw cover, so that each container with a standard screw cover can be provided with this closure.

The central region of the cover 53 is provided with an opening 58, for example rectangularly limited, on the outer edges of which flaps 59 are hinged 60. The flaps 59 are opposite, so that when they are opened they open an opening slot between their mutually opposing edges 61 through which the contents of the container can escape. The opening 58 is provided in its center with a beam-shaped support 62, on which the mutually opposing outer edges 61 of the flaps 59 rest in a sealed manner in the closed state. For this purpose, these outer edges 61 can be designed such that they cover the beam-shaped support 62 in the closed state on the upper side and on the two side surfaces with an angular profile 63.

The overall arrangement is preferably designed in such a way that all of the above-described individual parts consist of plastic and are injection molded together in a mold, the hinges 60 being designed as film hinges.

Arms protruding into the container neck 51 are integrally formed near the two side edges of the flaps 59, and are expediently in one piece and made of the same material as the flaps 59, this material being flexible or resilient due to the cross-sectional configuration of the arms 64. In its upper part, the arms 64 are provided with widenings 65, the lower and the two sides of the flaps 59 project downwards and lie against the sides of the openings 58 in the lid 53, so that when the flaps 59 swing open, the container contents cannot emerge towards the sides, but are directed towards the center exclusively through the slot formed between the two flaps 59. At its lower end, the arms 64 of the flaps 59 are connected to one another by a crossbar 66.

A leaf spring 67 is arranged below the cover 53. The free ends 68 of the leaf spring 67 are anchored in an annular part 69, which surrounds the inside of the cover 53 between the flanges 54 on the cover and the boundary of the opening 58 in the cover 53. The leaf spring 67 is shaped like a large W with long upstanding outer legs 70 and an inner short angle 71, which is connected at the apex 72 to the two arms 64, in such a way that it overlaps the rod 66 connecting the arms 64.

In the illustration in FIG. 12, the W-shaped spring is in a largely relaxed state. The arms 64 are also in their normal state and the flaps 59 of the closure are closed. However, the W-shaped spring 67 has a pretension, so that it acts in particular in its central region with the raised inner angle 72 on the connection 66 between the two arms 64, pulling it downward and thus holding the flaps 59 in the closed position.
The force of the spring 67 is adjusted in such a way that when the pressure on the container contents is not too great, that is to say when the container is compressed, the pressure on the flaps 59 acting inside the container has an opening effect by overcoming the restoring force of the spring 67. The flaps 59 open and the position corresponding to FIG. 13 is established, in which an opening slit is created between the two flaps 59, from which the container contents emerge in a compact, essentially rectangular strand. Depending on the pressure exerted on the container, the restoring force of the spring 67 is overcome to a greater or lesser extent, so that the flaps 59 open more or less, and accordingly between them resulting slot is larger or smaller. In this way, appropriate pressure on the container allows the contents of the container to emerge or the strength of the contents emerging from the container through the slot between the flaps 59 to be metered very precisely.

If pressure is no longer exerted on the container 52, the flaps 59 close under the action of the restoring force of the spring 67. The compact strand of the container contents which has emerged from the container is cleanly separated by the closing flaps and the flaps press a last remaining remainder of the leaked container contents back into the container due to their closing movement. Compared to the beam-shaped support 62 and due to its special shape with the inwardly taken angle profile 63, which produces a stripping movement downwards with its vertical leg relative to the beam-shaped support 62.

For secure closing, for example when not in use for a long time or during transport, an additional securing device can be used, namely a cap, which is not shown here, which lies flat on the two flaps 59 from the outside and above with a central part and with one after the bottom edge is clipped on to the flap 55 or screwed onto it. It is also possible to use a sealing cap instead of this additional cap, which is similar to the cap 55 and is exchanged for this, the sealing cap, also not shown here, being continued in one piece between the inwardly projecting projection 57, so that this central one Part rests on the outside of the two flaps 59 when screwing onto the thread 56 in a tightly sealing and sealing manner.
The closure is designed in particular with regard to the arrangement of the spring such that it forms a coherent unit.
