Description

EASY OPENING CLOSING VALVE FOR BOTTLES

The present invention relates to an easily opened shut-off valve for bottles, which comprises a stationary portion of an internal valve that can be installed in a bottle neck and which has a valve cap 5 and devices for sealing the neck, and an axially movable external valve portion which has a valve opening for fitting with the valve cover and a screw cap which is connected to the valve opening and which has a female thread of a nominal radius r and is engaged with the thread male of a threaded connection portion, fixedly connected to the valve cover.

Accordingly, the design configuration of the bottle can be substantially any and the term 'bottle' also includes other containers for loose goods, in particular for liquids, preferably involving bottles or other plastic material containers.

A corresponding valve closure is known in the art. Among others, the so-called push-pull closures are known, for example, for beverage bottles, which are, in principle, very similar to the present closure, but do not have a threading, but in which the outer portion of the valve is simply movable by pulling and pushing axially with respect to the inner portion of the valve, where the valve cover and the valve opening are correspondingly brought to and from the fitting.

In addition, however, a closure is also known in the prior art, in which the portion of the external valve is formed by a screw cap which, however, is of a larger diameter. These closures with a screw cap valve, the screw cap of which has a relatively large diameter (for example, greater than 25 mm) are used, in particular in relation to bottles with liquid cleaning products, in which the bottles which generally comprise plastic materials can be compressed, so that in this way they are able to easily measure the amount of liquid emission 30 when the valve is opened.

Plastic bottles with push-pull closures whose outer portion of the valve is smaller in diameter (up to a maximum of 20 mm) are used;

for example, for household chemicals, but also for bottles (drinks, for example, for people who play sports!

corresponding bottles with them, in which case the bottles are frequently?

exposed to jolts, are possibly transported in a horizontal position and, ΐ

2/13 in this case, they must remain substantially sealed, while on the other hand, they must be suitable for use during the active participation or performance of a sport, such as cycling, running or similar. The person playing sports is (and wants) to be able to drink from the bottle, therefore, while performing in his sport, pulling the outer portion of the valve axially outward a little and opening the valve and placing it in his mouth, to then deliver the drink in the mouth by suction or pressure on the outside of the bottle, without the risk of spilling the drink or spray on the body or clothing of the person playing sports. In that case, the outer valve portion is fixed to the inner portion in such a way that it cannot be pulled completely out of the inner portion, but is substantially axially returnable only between a closed and an open position.

A disadvantage of all known closings of this type, however, is that it is only very difficult and complicated, at least, to open the valve with just one hand. The valve cover and also the external portions of the push-pull closure are relatively fixed in their closed position so that they are not intentionally released under the influence of agitation and some force is required to pull the outer portion of the valve out of the valve cover. valve or vice versa to pull a valve cover out of the valve opening. Both hands are usually needed for this purpose. Both opening and closing through the teeth, holding the outer portion of the valve with the teeth and pulling the bottle, is relatively risky and can lead to damage or loss of teeth, being practiced by only a few users. Furthermore, in the best known closure that has a screw cap with a valve opening, the bottle has to be held firmly with one hand to release the cap, rotating it with the other hand, in order to open the valve, this it is to turn the screw cap in order to move it axially so that the main plate of the cap with the opening of the central valve comes loose from a valve cap of the inner portion of the valve.

When opening the beverage bottle with both hands it is sometimes bothersome, and can also be disadvantageous for other reasons when dealing with other liquids, such as household chemicals or cleaning fluids. In particular, the fingers of a hand can then more easily come into contact with such a liquid, which in many cases can cause damage and / or cause allergies, or in other cases can lead to adulteration and

3/13 contamination of the liquid, such as, for example, in the case of contact lens cleaning agents that are subject to the risk of germ infestation.

As already mentioned, the operation of opening beverage bottles that are intended to be used during a sporting activity or another is very annoying, if both hands have to be used as in many types of sport, for example, when riding a bicycle, both hands are not always free, particularly not when, for example, road conditions or other conditions do not allow cycling without hands. In addition, in the case of (long distance) running bringing both hands together on the beverage bottle or the closure being able to open it disturbs the rhythm of functioning of the person in question and is therefore considered harmful.

Therefore, it is desirable to have a corresponding valve closure, which on the one hand can be used in the usual way as a push and pull closure that also fits tightly and sealed over a portion of the internal valve with the agitation that normally occurs, but on the other hand it allows simple and quick opening with just one hand.

This object is achieved insofar as, on the one hand, a closure with a corresponding screw cap is used, where, however, the screw cap is in turn connected to a drive lever that extends radially out of the cap. threaded so that the lever radius R defined by the radially outer end of the actuation lever is at a spacing from the cap thread axis, which is at least 20% greater than the nominal radius r of the female thread (14) .

In this sense, the screw cap is approximately shaped and the size of the external valve portions of the known push-pull closures and must be of an outside diameter not exceeding 25 mm, preferably not exceeding 20 mm. Correspondingly to the nominal diameter 2r of the female segment of the screw cap (and, consequently, also the nominal male thread diameter of the threaded connection portion) is relatively small and is typically in the range of 8 to 15, preferably in the region between 10 and 12 mm. The outer diameter 2R of the screw cap that forms the outer portion of the valve that is normally placed in the mouth when drinking such a bottle is therefore of a value of the order of magnitude between 12 and 18 mm, usually between 14 and 16 mm. Note, however, that in contrast to the usual push-pull closure this screw cap does not need a radially upper projection edge which in the case of push-pull closures possibly serve

4/13 as an exciting aid being able to exert adequate axial attraction on the closure to open the valve.

In contrast to the closure according to the invention the axial movement is produced by the rotation of the screw cap. Note, however, that the screw cap itself is not taken for this purpose, but rather a drive lever that extends radially out of the screw cap so that the lever radius R set to the radially outer end of the lever it is a relative in spacing to the cap thread axis, which is at least 20% larger than the nominal radius r of the female thread. It will be appreciated that the outer end of the lever may still be at a substantially larger spacing from the screw cap axis, which, for example, is between two and three times the nominal radius r of the thread, but slightly greater spacing at from the axis already provides that a greater force can eventually be applied to the screw cap by means of the lever, than is possible by holding the screw cap, which in many cases is smooth and small.

According to the invention, therefore, the screw cap has an actuating lever in the form of a radial projection, the end of which is radially external at a greater spacing from the axis of the screw cap than the outer peripheral surface of the screw cap. thread that is normally cylindrical or slightly tapered or cylindrical has also intensified and is also at least relatively smooth. That the actuation lever can rest, for example, on the upper side of a radial widening of the internal valve portion. Often a bottle neck on which such a closure is mounted is of a markedly larger diameter than the axially movable outer valve portion of a push-pull closure and the associated inner portion connecting the inner portion of the valve. Therefore, under the valve portion connecting the inner portion of the valve it usually has a radially markedly enlarged portion with a closing flap forming the transition to the neck yet, is mounted on the neck of the bottle and makes a sealed connection between the rim of the neck of the bottle and the inner portion of the valve. Therefore, a suitable lever may, for example, be over this radial widening, which is typically in the form of an annular disk so that it is better protected from unintentional actuation, because it is not a mere loose design of the screw cap of the portion internal valve. The preferred modality in this sense is that in which the lever is rotatable on the screw cap axis on a disc

ES h

5/13 annular portion of the internal valve portion, which extends around in relation to the threaded connection portion and extends radially and towards the periphery.

It is also possible for a plurality of levers to be arranged for design in different directions at the same time from the screw cap, for example, in the form of spokes on a wheel, which are preferably distributed in uniform angular spacings around the periphery a screw cap.

In addition, it is desirable if the radially outer end of the lever or the levers extend in parallel and with a small spacing with respect to an axially extending end portion, radially outer of the inner valve portion. The lever then extends, for example, from the bottom edge of the screw cap along the top portion of a radial widening from the inner portion of the valve to its radially outer edge and slightly extended, then later extending into the parallel axis downward relationship along the outside of the widening of the inner valve portion. It is the lever portion that projects slightly the surface of the outer edge of the enlargement can be easily gripped with one finger, preferably with the thumb, on one side and moved in the direction of opening, while the other fingers of the same hand hold the bottle. It will be appreciated that this assumes that the bottle or a corresponding container, below the closure region, is of dimensions that make it possible for the bottle or container to be actually held with the fingers of one hand and the ball of the hand or the tip of the thumb, while, for example, the thumb remains free for the lever to act. However, the invention can be used even in relation to bottles or other larger containers as it is sufficient that the bottle remains firm on the floor or a supporting surface or possibly can be performed quickly with a portion of a hand to what he does is not easily rotate with a finger or thumb, which remains free triggers the lock or the lock lever.

Finally, it is also possible for corresponding levers to be connected in spoke form to a peripheral ring extending so that this effectively provides an actuation ring in which the spokes can optionally be replaced by a closed annular disk that makes the connection with the ring external actuation and the screw cap more internally removed. However, a drive ring with a few spokes is preferred as the actuation ring means that the individual spokes or levers are better protected from actuation.

6/13 intentional, the ring gives good stability to the entire actuating element and, finally, the ring requires only little additional material and is also very well adapted as an actuating element. In other words, therefore, the radially outer end of the lever is in the form of an actuation ring extending peripherally with a spacing around the screw cap.

Preferably the ratio of the outer diameter D ( ⁼ 2R) of the actuation ring to the thread diameter d (= 2r) of the screw cap is in the region of between 1.2 and 3 and the corresponding ratios approximately also apply to the ratio between the outer diameter of the actuation ring to the outer diameter of the screw cap 10 which is larger than the thread diameter just by the thickness of the screw cap wall.

Because of the larger diameter of the actuation ring, a transmission lever with a step-up effect is effectively provided in the corresponding order of magnitude for the actuation of the thread of the cap thread, which is substantially smaller in diameter. It is also possible for such an actuation ring to be arranged, for example, in the region of a neck mouth and of approximately the same diameter as the neck mouth so that it is easily accessible while the usual push-pull closures including those that are suitable for seating and intended to be placed directly in the mouth to drink from a container are often turned radially in relation to the neck of the bottle so that even if the bottle is held quickly with one hand in the region of the neck of the bottle, it can only be reached with difficulty and grabbed by the fingers of the same hand.

However, according to the invention, there is provided a lever for actuation or a ring that is of a large diameter or the radius of actuation and that of these designs of the screw cap of the outer portion of the valve that is relatively easy possible for hug the bottle, for example, below the actuation ring or close to the neck of the bottle with your hand, in which case the example thumb points vertically upwards, and then apply the 30 thumb to the outer portion of the actuation ring and transforming the actuation ring by lateral movements of the thumb.

It will be appreciated that, for this purpose, in a preferred embodiment of the actuation ring it has a serration on the outside that significantly increases the friction between the fingers or the thumb of a hand and the actuation ring and, therefore, allows the strength to be more easily and more

7/13 simple applied to the thumb or fingers ring This serration, however, does not involve the screw cap, which makes it more suitable for drinking from the bottle.

It is desirable in this regard if the actuation ring, the screw cap and the threaded connection portion have the same common axis, even if it would be possible, in principle, for the actuation ring to be eccentric.

As already mentioned, the relationship between the diameter of the actuation lever and the thread diameter should be in the order of magnitude between 1.2 and 2.5 or 3, but if possible the radius inside the actuation ring must be at least 50 greater than the thread radius on the screw cap and the threaded connection portion. In one embodiment of the invention, for example, the thread diameter is 12 mm, while the inner diameter of the adjustment ring is about 28 mm and its outside diameter is about 30 mm. It offers an effective leverage rate of almost 2.5, which considerably facilitates one-handed closing.

The fastening devices sealed from the inner portion of the valve by neck preferably include a U-shaped closing flap of cross section so that the closing flap embraces the edge of the neck from the outside, above and inside. Such a closing flap, including its connection with the inner portion of the valve, forms the cylindrical widening of the inner portion of the valve, as already mentioned earlier in this document. The inner portion of the valve and in particular the closing flap may itself have known locking elements to cooperate with corresponding elements of the bottle neck to prevent rotation of the inner portion of the valve in relation to the bottle neck.

The actuation lever which is preferably in the form of an actuation ring is preferably located with its portion extending between the screw cap and its outer end (that portion being specifically the spokes) in the upper portion of a radial widening the inner portion of the valve that connects the connecting valve portion to the closing flap. The outer end of the lever or in the preferred embodiment the actuation ring, in this case, covers the outer portion of the closing flap and extends substantially parallel to the common axes of the closing portions.

In this way, the outer end of the lever or the actuation ring is (oriented on the upper outer shoulder of the closing flap.

Preferably the threaded connection portion and the screw cap must have axial pillar elements that limit the reproduction of the axial movement of the?

screw cap in relation to the threaded connection portion. In particular, both

8/13 the threads by screw cap and the threaded connection portion, more precisely the thread overlap, are of a correspondingly short axially configuration so that they come out of coupling when the screw cap has been moved axially so far that the valve cover and the valve opening are sufficiently far from each other to be able to drink straight out of the opening, or to be able to press out the liquid. In addition, for example, externally and internally projecting spheres can be provided on the external portion of the threaded connecting portion and on the inside of the screw cap, respectively, which in any event do not allow the screw cap to be pulled axially out of the portion threaded connection without application of considerable forces.

Preferably the main elements are, respectively, provided in an upper portion of the threaded connection portion and the screw cap, which is of a reduced diameter in relation to the nominal thread diameter. 15 In this way, the thread can be moved axially out of the main elements and brought into the socket with the threaded connection portion.

Other advantages, characteristics and possible uses of the present invention will hereinafter result from the description of a preferred embodiment and the associated Figures 20 in which:

Figure 1 shows an axial section through a preferred embodiment,

Figure 2 shows a plan view of the closure of Figure 1 in an axial direction from above,

Figure 3 shows a section corresponding to the section in Figure 1 with another simplified modality, and

Figure 4 shows a top view of the closure shown in Figure 3.

Figure 1 shows an inner valve portion 1 and an outer valve portion 11, each characterized by different hatches. The inner portion of the valve 1 includes a closing flap 7 and a threaded portion of central connection 4 which is connected to them by means of an annular disk 6 and the wall within which a plurality of members 3 extend radially inwardly, these members axially carrying upwards a | Extended valve 2, the upper portion thereof being in the form of a closed cylinder I ³⁵ ascendente.í Lily The binding threaded portion 4 in turn has an attachment portion | narrowed top 4a and a threaded bottom portion 4b which is a little bit!

9/13 radially extended in relation to the fixing portion 4a. The small diameter of the fixing portion 4a, in the vicinity of its upper end, has an outwardly projected edge 9, which serves as an axial pillar element for a radially inwardly designed fixing edge 19 within the screw cap. The fixing portion 4a and its edge 9 are of such dimension in relation to the threaded portion 4b with the thread 8 whether the internal diameter of the female thread 18 of the screw cap 13 is at least as large as the external diameter of the edge 9, while the free inner diameter of the projecting fixing edge 19 inside the upper portion of the screw cap must obviously be smaller than the outer diameter of the edge 9 so that both strands can serve as axial pillar elements that limit the movement clearance axial of the screw cap with respect to the threaded connection portion 4 or with respect to the portion of the entire internal valve 1. The cross-section of the fixing edge 19 is therefore of a somewhat flattened shape, that is, its smallest flank includes a smaller angle with the axis 20 of the closure than the top flank so that it can be recognized had passed edge 9 for mounting purposes in the axial direction with a slight expansion of the compression screw cap portion 13 and the connecting threaded portion 4 in the edge region 9, and then locking behind the edge 9. The release of the screw cap movement is limited downward in the axial direction interior alignment by placing the main plate of the screw cap 13 on the upper edge of the threaded connecting portion or also by the lower end of the screw cap 13 with the radial widening of the inner portion of the valve 1 being applied.

The lower end of the threaded connection portion 4 is delimited by a radially and peripherally extending annular disk 6 connecting the lower end of the threaded connection portion 4 to the closing flaps 7 which is of a U-shaped cross section. U shape surrounds the top edge of a corresponding bottle neck that is not shown here and the outer U-shaped member has a projected inner edge of attachment 22 and the inner member of the closure flap to an externally designed sealing edge 23, which fits into the seal with the inner surface of a bottle neck (not shown). At the same time, the annular disk 6 also forms the cross section of the U-shaped portion, which joins the inner and outer U members.

The outer portion of valve 11 substantially comprises a screw cap 13 with a female thread 18, where that female segment 18 is

10/13 provided only with the lower portion of the screw cap 13 and preferably extends at most over the lower half of the screw cap 13, as well as a drive ring 15 connected to the screw cap 13 by means of spokes 16. The upper portion of the screw cap is of a somewhat radially narrowed configuration with respect to the lower portion, which is basically advantageous for reasons of saving material, but on the other hand it is also not absolutely necessary only as long as the female thread of the 18 portion bottom of the screw cap is of an inner diameter larger than the outer diameter of the edge 9 in the threaded connection portion 4.

¹⁰ screw cap 13, in turn has a main plate 14 which is slightly domed in its central region and in the central region also has an opening valve 12, which in closed condition receives valve cover 2 in a suitable sealing relation . In addition, it extends in the axial direction of the main plate 14, there is also a sealing ring extended peripherally 24, which interacts with the internal surface of the fastening portion 4a of the threaded connecting portion 4, in order to completely seal the screw cap 13 with respect to the threaded connection portion 4 in the closed condition and, generally, to prevent liquid from escaping through the thread.

In this embodiment, the lower end of the screw cap 13 is connected by means of three spokes 16 to an external actuation ring 15, which is in the L-shaped cross section, in which a smaller L-shaped member rests on the annular disk 6 of the inner closing portion and an axial member extends parallel to the outer member of the closing flap 7 and substantially supports the opposite, that is, the inner diameter of the axial member of the actuation ring 15 substantially corresponds to the outer diameter of the closing flap.

Furthermore, as can be seen clearly in particular from the Figure

2, the actuation ring on its exterior has a knurling 17 that facilitates the actuation of the closure by holding with just one finger or the thumb of one hand.j

I Turning the actuation ring in the open direction also involvesI transmitting a corresponding force through the radius 16 to the screw cap so that, because of the threaded fitting of the female thread of the screw cap with the male thread of the threaded portion of connection 5, cover the screw Z

Together with the drive ring 15) it is moved upwards in the axial direction;

until the threads come out of the socket, in which case, in addition to the 9.1 column elements

I 11/13 prevent further axial movement of the screw in relation to the cover 13 the threaded connection portion 5.

In that case, the main plate 18 is also moved upwards with the screw cap 13 and as a result the valve cap 5 comes out of slot with the opening 5 of the valve 12, so that the liquid can now emit through that valve opening when the corresponding container or bottle is turned over and / or under external pressure.

Desirably the length of the axial member of the actuation ring is greater than the axial movement clearance of the screw cap 13 with respect to the threaded connection portion 4, which is defined by the elements described above abutment, the axial extension of the thread and placement of the cap of the annular disk 6 or at the upper edge of the threaded connection portion 4.

When the screw cap is screwed by action on the drive ring 15 in order to close threads on the screw cap and the threaded connection portion 15 is engaged again, in which case the screw cap moves axially downward so that finally, the valve cover 2 slides into the opening valve 12 again and closes in a sealed manner.

In this way, a closure is provided which in its function substantially corresponds to the so-called push-pull closure, but has a screw cap 20 that is operable with only one hand, due to the actuation lever provided.

Figures 3 and 4 show more incorporation, even if it is not absolutely preferred. According to a similar variant (not shown here), instead of an actuation ring, there is only an actuation lever 25 16 that extends only on one side of the screw cap 13 and which substantially corresponds to one of the 16 spokes in relative to a small portion of the drive ring 15 in Figure 3, where the 'spoke' or the 16i lever is just a little more stable to increase its stability. In the modalityj in Figures 3 and 4 there are in each case, three arms such 16 ', equal spacingsI angular 120o.I

The method of operation of this closure is substantially the same as that of the embodiment described with reference to Figures 1 and 2. Here too, it is | possible, for example, to hold a bottle or other container with one hand and in doing so still leave the thumb of the same hand free and pointing upwards, so that the outer end of lever 16 'can be contracted with the thumb and moved in the direction of opening or closing,

12/13 respectively. If only such a lever 16 'is, since it will be appreciated, however, that there is the disadvantage that, for the situation in which the rotation of, for example, much more than 120o is necessary to open the closure, the hand has to be more connected, again with respect to the bottle and therefore it is necessary again to change the grip to be able to turn the lever 16 'far enough.

In an alternative embodiment, therefore, for example, it would be possible to supply two levers diametrically opposite 16 Or, as shown in the case of Figures 3 and 4, also three (or more) corresponding levers 16 'that 10 could substantially correspond to the 16 spokes of the incorporation shown in Figure 2 and that with its free ends design beyond the outer edge of the closure, as shown both in the section in Figure 3 and also in the plan view of Figure 4. In this case it is possible to reach the next lever 16 'after the rotation of the closure through a corresponding angle 15.

Even if such a design configuration is easily possible and basically also possible, however incorporation with an actuation ring, as shown in Figures 1 and 2 is preferred.

In particular, the preferred embodiment with the actuation ring 20 also allows easy organization of the tamper-evident fastening elements, such as, for example, a conventional cutting strip.

For example, a tamper-proof band can be arranged under the actuation ring and can be connected to the actuation ring via a weakening line. The tamper-proof seal can be secured in relation to a rotating movement, for example, interlocking the knurling on the neck of the bottle and the tamper-proof band so that it has to be removed first, if before or the ring of adjustment is rotated.

For the purposes of the original disclosure it is noted that all features as seen by a man skilled in the art of the present description, the drawings and the claims, even if they are described in specific terms only in connection with some other features, can be combined both individually and in any combination with others of the characteristics or groups of characteristics disclosed here to the extent that it has not been expressly excluded or technical aspects make these 35 combinations impossible or meaningless. The comprehensive explicit representation of all possible combinations of characteristics and emphasis of independence

13/13 of the individual characteristics of each other is waived here only for the sake of brevity and legibility of the description.
