The invention relates to a closure for containers such. B. bottles, glasses, cans or the like., And in particular a removable cap which can be reused after it has been removed. The invention also relates to a method for closing containers with such a closure.

Most of the known caps that are used to close containers, such as. B. bottles or cans, Find use, must be deformed when removing, so that they can be used for a further closure the bottle or can are unusable. This is especially true when it is necessary or desirable make a tight seal to prevent air or liquid from entering the container or is intended to prevent gases or liquids from escaping from the container. Screw caps generally leave reuse, however, are often difficult to remove and manufacture as well as those of the associated bottles or cans provided at their upper end with a screw thread is costly. There are also various types of non-metallic closures for bottles or cans known, but they have serious disadvantages; many of them are too costly to use after to be thrown away. Other closures, on the other hand, do not close the container sufficiently reliably away. In general, non-metallic closures are also too easily detachable from the associated container. Other known closure caps require od for their attachment to the bottle. Like. Expensive Facilities.

For example, a closure has become known whose cap on the circumference with almost to the transverse wall Reaching wedge-shaped incisions is provided, which widen the cap when it is put on should lighten the edge of the container. A special holding or holding device is then placed over the attached cap. Circlip pushed to prevent the slotted lower edge of the cap from spreading. However, the incisions not only significantly reduce the strength of the closure, but also the sealing surface between the container edge and the closure cap is also reduced. If you try such a closure for closing carbonated beverages Use bottles that have a changing internal overpressure in the event of temperature fluctuations develop, the elastic transverse wall of the closure cap would stretch, and finally so far lift off the edge of the bottle neck so that the ends of the incisions are exposed and the contents of the bottle let escape. This risk is also given because the locking ring is known Closure in the axial direction only very container closure

is narrow and the cap includes only at the lower edge and pressed against the bottle neck holds. This known closure has in the head an elastic sealing plate made of cork or the like the closure cap is pressed against the face of the container opening. So the seal only takes place frontal and is therefore not very reliable.

There is also a closure known in which a sleeve-shaped part of the cap is also axially running, over its circumference distributed incisions is provided. Here, too, the actual takes place Seal by an insert made of cork or the like. The cap of this closure is on the outside of her The lower edge widens conically and is only there by sliding over a special locking ring compressed inwards against the bottle neck and around its outer bead. Also this one Closure does not seal reliably and in particular is not able to absorb internal excess pressures.

Another known closure consists of a non-slit cap, which is taut over the neck of the bottle is pushed and has no special sealing insert, but both on the end face to seal the bottle as well as on the circumference of the bottle head itself. To this end owns the sleeve-shaped part of the cap at its lower end has an outer annular bead that has a conical contact surface merges into the overlying cylindrical part. One after putting on the Cap tightly over this downwardly pushed rigid retaining or locking ring finally runs up

the conical ring bead and thereby presses the outwardly bead-like reinforced lower edge the closure cap inwards until it rests on the bottle neck, with the, lower edge of the cap the outside bead of the bottle head is lying around.

However, the locking ring of this fastener is very "narrow" and therefore only holds the lower one The edge of the cap is pressed against the neck of the bottle. However, there is a risk that the security

^: this training, the downwardly pushed locking ring is held even more securely in its position.

Furthermore, the invention provides that the cap edge at its lower end with a radially outwardly projecting flange which limits the sliding on of the locking ring is. ■.

But you can instead "of this the locking ring at its upper end with a radially after

Ring ring unintentionally shifts up again and protrudes inside, pushing it onto the verden The edge of the cap releases the flange which then defines the cap, expands elastically to its original diameter and practically removes the seal.

Hand higher than that of a one-piece fastener. have preferably a tongue that is attached to the The invention has for its object to seat a radially protruding flange of the closure cap. To create a container closure, which consists of a combination In addition, it is provided that the bottom of the closure cap Made of soft elastic, stretchable factory end cap provided with an annular notch fabric as well as one on the attached cap, while the locking ring is one with perforation

slidable from above, connected in one piece with the cap edge by a shearable web There is a locking ring and the disadvantages of the known Avoids closures of this type.

The invention consists in that the locking ring, the height of which is equal to the height of the edge of the Closure cap and the inside diameter of which is equal to the outside diameter of the closure cap, over adjoins the cap base and shearing off the web on the peripherally uninterrupted in a known manner Cap edge is slidable. The locking ring thus covers the in the pushed-on state sleeve-shaped part of the closure cap over it

has stanchions or a floor that can be easily perforated afterwards. Such a closure can then after opening the container to serve in the container located grit, z. B. Salt, pour out. Finally, the bottom of the closure cap can also be used easy to perforate and the locking ring with a perforated bottom opposite the cap be rotatable.

Finally, it is provided according to the invention that several closure caps are connected via webs that in turn are connected to one another via crossbars. Such a multiple lock connects several Bottles or the like with each other and thereby enables

total axial length. This makes any radial 40 comfortable to wear. Prevents deformation of the sleeve-shaped part and legs, the closure cap and the locking ring Significant increase in the strength of understanding, preferably from a soft elastic artificial fit, especially against a possible material, especially made of polyethylene, ■ internal overpressure of the container filling, achieved. Except- The locking ring of the cap can through due to the wide cylindrical design 45, this is a forceful pressure or blow by hand the circlip increases the friction significantly and sheared off the top of the cap and over and an unintentional sliding back practically these are pushed. Preferably, however locked out. a method for closing containers with the closure according to the invention can also be proposed to the closure, which consists in that due to its one-piece and simple training 50 after pressing the cap over the very 'cheap, for example as a molded part. Container opening the container closed as far as possible Due to the arrangement of the locking ring over on a conveyor belt under a roller The bottom of the cap is finally reached, which is guided by the locking ring under Abder sleeve-shaped part when the locking scissors of the web are placed telescopically over the locking cap on the edge of the container unhindered in the radial 55 cap pushes.

In FIGS. 1 to 5, the closure cap is denoted by the reference numeral 30 together with the retaining ring. the actual cap 32 has a flat bottom 34 and a rim 38. This is inside with a annular bead 40 is provided, which when the cap is placed under the neck bead 42 of the bottle 36 comes lying and is supported against the bulge 44 of the bottle neck. The bead 40 in the cap edge 38 is offset against the cap base 34 by a groove 46 which is used to receive the bottle mouth bead 42 serves. The closure cap 32 is seated along the connecting line of the cap base 34 the cap rim 38 a ring 48. This connection is made in one piece with the closure cap and the ring formed ridge 50 which, when the ring is pressed over the top by a pressure from above Closure cap is pressed, is sheared off.

Both the cap and the retaining ring are made of an elastic or deformable material, like polyethylene. The inner diameter of the retaining ring 48 and the outer diameter of the cap rim 38 are essentially the same size before the cap is attached to the bottle, as shown in FIG Fig. 3 can be seen. When the cap is pushed over the neck of the bottle, it stretches a little, whereby the outer diameter of the cap rim 38 is slightly larger than the inner diameter of the Retaining ring 48; at the same time, the cap edge assumes a somewhat conical shape, as can be seen from FIG is. If the retaining ring is pressed over the cap, it expands when it is pushed on the cap edge, embraces the same tightly and presses it tightly against the bottle neck, the inner bead 40 of the closure cap is deformed so that it clings to the bottle mouth, like this from Fig. 5 can be seen. The bottle is then closed sufficiently tightly for shipping; she can can be used for a wide variety of contents, for example to take in ketchup or others Sauces or spices, but also for numerous other goods. The cap will stay tight in place for a long time and held in place as the ring surrounds the cap rim. To remove the ring from the cap To facilitate, for example, when the contents of the bottle are to be used, the ring can be on its outside with bumps or the like. Or with a corrugation 52 are provided. After removing the ring the cap can be pulled off the bottle neck by hand without the need for additional tools are needed; if necessary, a simple tool, such as a table knife, is sufficient for the honing to facilitate the cap. Since the closure cap is made of elastic material, it will not damaged by pulling it from the bottle neck; so it can easily be used again. The stretching of the cap rim causes the cap to sit sufficiently well on the bottle neck when it it is simply a matter of keeping the opened bottle in the house. However, the cap is then seated not nearly as tight on the neck of the bottle as when the retaining ring is slipped over it. A filled one However, the bottle cannot be shipped without the cap on and the retaining ring over it is pushed.

The retaining ring 48 can, as shown in Fig. 5a, above the closure cap extend and be provided with an inner groove 51, which serves to receive a disc 53, on the information on the contents of the bottle or any advertisements.

A somewhat different embodiment of a closure cap according to the invention is shown in FIG. This closure cap enables the retaining ring to be removed more easily. The parts of the closure cap shown in FIG. 6 are essentially the same as those described in FIGS. 1 to 5 and are also provided with the same reference numerals, but with the index "α". The closure 30 a consists of the cap 32 a and the retaining ring 48 a. The outer surface of the retaining ring can be corrugated, as shown 'in the drawing. The retaining ring is provided with a grip tongue 54 which is arranged approximately at right angles to the axis of the closure cap. The cap and the

Retaining ring are originally in the manner described above by a shearable, narrow, annular web connected to each other.

Another embodiment of the closure according to the invention is shown in FIGS. In this embodiment, those parts which correspond to the parts described above are provided with the same reference numerals with the addition of the subscript “b” . The cap 32 of the end piece 30 b Ver again comprises a bottom 34 and an edge 38 b on b. This edge is also provided here with an inner bead 40 & and with a groove 46 & for receiving the mouth bead 42 b of the bottle 36 b . The retaining ring 48 & is not fluted on its outside, but is provided with a projection 56 which makes it easier to remove the retaining ring from the closure cap. The retaining ring is not connected in one piece to the closure cap by a shearable web, but by a flexible band 58. This band is bent while the ring is pushed onto the closure cap and at the same time serves with the projection 56 as an aid when removing the retaining ring. The cap rim normally has an outer diameter which is equal to the inner diameter of the retaining ring, but this outer diameter increases when the cap rim is pushed onto the bottle neck, so that the retaining ring must also be stretched in order to seal the edge of the cap when it is pushed over the cap In this way a secure fit of the cap on the upper part of the bottle neck is guaranteed. The flexible band 58 represents a safeguard against losing the retaining ring. The retaining ring can easily be pushed back over the closure cap after it has been replaced on the bottle neck, in order to ensure that the closure cap is seated as firmly as possible. In the exemplary embodiments described at the outset, the ring could also be connected to the cap by a band in the manner just described. The flexible band 58 can also be cut with scissors or the like and the cap can be used again on its own, that is to say with the ring removed. A plastic, preferably polyethylene, is preferably also used as the material for the closure shown in FIGS. 7 and 8. '

Another embodiment of a closure according to the invention is illustrated in FIGS. 9 and 10, and this is a closure for a salt shaker or the like. The closure cap corresponds to FIG their construction of the closure cap according to FIGS. 7 and 8, and the same parts are here also with the same reference numerals with the addition of the index "c". The closure 30 c includes the cap 32 c, whose Bottom 34 c has an incised or incised line of weakness 60. The cap rim 38c is provided with an inner annular bead 34c, which secures the connection between the cap and the bottle neck 36c relieved. The retaining ring 48c is closed on its upper side by a bottom 62 which has a plurality of holes 64. Furthermore, the retaining ring with the actual cap is flexible Band 58c connected. For shipping, the cap and retaining ring are used in the manner described above placed on the neck of the bottle. The consumer separates the bottom 34 c from the cap by pushes or cuts it out along line of weakness 60, and then pushes retaining ring 48c again over the cap edge 38 c. The holes 64 are preferably in the ring base from the outset 62 attached; but if they are not there it is easy to find them in the rather soft ones Pierce the material. The bottle 36c can then be turned upside down and used as a shaker for salt

5 or the like. Can be used. The grit can be supplied in the bottle, but you can also fill the bottle with the grit later. The bottle and the perforated cap can also be used to spray water or other liquids, for example to dampen clothes or laundry items to be ironed. It is also possible to perforate the cap base 34 c instead of separating it out, and make the ring 48 c rotatable with respect to the cap in order to be able to bring the perforations 64 in the ring base 62 into a cover position with those in the cap base 34 c.

In certain cases it may be desirable to use a retaining ring made of a hard or non-elastic material. Since the closure cap must be flexible or elastic, it is advisable in this case to produce the cap and retaining ring separately. If, on the other hand, one and the same material is used for the cap and the retaining ring, different heat treatments or chemical treatments must ensure that an elastic cap and a hard, inelastic retaining ring are produced. A closure cap, the retaining ring of which is made of a hard or rigid material, is shown in FIGS. 11 and 12. Since the general structure of the closure is again the same, the same reference numerals have been used, but with the addition of the index "d". The cap 32 d of the closure 30d in turn consists of an elastic material, for example polyethylene. The cap is with a bottom 34c? Mistake. The cap edge 38 d has an annular bead 40d on the inside. Further, the cap skirt is provided at its lower end with a radially outwardly extending flange 66 which serves to limit the displacement of the retaining ring 48 d downwards. A radially projecting lug 68 is also provided to facilitate removal and replacement of the cap on the container neck. The retaining ring 48 d in this case forms a completely independent element. It can be made of metal or of a hard plastic that is not able to stretch significantly, so that the ring is able to hold the closure cap on the container neck much more firmly than is the case with the embodiments described above. The flange 66 limiting the displacement of the ring can of course be provided in all cap designs; However, it is particularly useful when the cap and retaining ring are made of different materials, that is, when the inelastic ring has to be pushed onto the cap with great force.

The container closure according to the invention can

can also be used as an organ for carrying a large number of bottles or cans. It is often desirable to group a wide variety of bottles or cans into units of, for example, half a dozen. Numerous carriers or containers have been developed for this purpose. 13 to 16 illustrate the combination of several closures to form a support member. In these figures, too, the same parts are again provided with the same reference numerals, but with the addition of the index “e” . The caps are denoted by 32 e and the retaining rings by 48 e. Each cap has a bottom 34? uiid one

Edge 38 e with an inner annular bead 40 e . The cap rim 38 e is held on the bottle neck 36 e in that the annular bead 40 e engages under the mouth bead 42 e of the bottle. The retaining ring 48 e can also here again integrally with the closure cap by a shearable web or the like or may be connected by a flexible band..; however, the retaining ring can also consist of a different material than the closure cap and form a completely independent element which is separate from the cap. ib This latter case is illustrated in FIG.

The new and progressive feature of the embodiments according to FIGS. 13 to 16 is that several closure caps 32 e are connected to one another by flexible webs 70. These webs 70 are in turn connected to one another by transverse webs 72, corresponding to the injection channels of the injection mold that are integrally connected to the center piece 74. The webs 70 secure the mutual position of a number of bottles, and the entire group of bottles can be lifted simply by putting the fingers under one or more connecting cross-webs 72. Here, too, the webs and the cap are made of an elastic material, preferably polyethylene. This material is sufficiently soft to be able to separate the bottles from one another after cutting through the strips with a knife or scissors. The bottles can also be separated from one another by removing their caps one after the other. 30 ·

In all the embodiments described above, the closure caps are provided with ribs or beads on the inside, which grip under the mouth bead of a bottle. The closure cap can also be used for wide-necked containers with a bead of a relatively large axial length. With such containers it is sometimes impractical to design the closure cap so that it extends below the container mouth bead. In these cases, the closure cap at the Behältermündungs- ^ o can bead held in place by friction, as is illustrated in Fig. 17 to 22. In these figures, too, the same parts are provided with the same reference symbols as in the aforementioned figures, but with the addition of the subscript “/”. A 45 'can-like container 36 / is shown which has a relatively high rim 42 /. Cans of this type are often used for packaging canned fruit or the like. The closure 30 / in turn comprises the closure cap 32 / and a retaining ring 48 /. Closure cap and ring are connected to one another by a narrow, shearable web 50 /. The closure cap consists of the bottom 34 / and the edge 38 /. Because of the relatively large height of the container bead 42, the cap rim is not provided with an annular bead on its inside.

As a result of the large diameter of the closure cap in relation to its height, the cap is here more flexible than in the embodiments described above. The retaining ring could therefore more easily accidentally removed from the cap by accidental forces. To do this prevent an annular rib 76 is provided on the outside of the cap sleeve, while the inner wall of the retaining ring 48 / has a corresponding annular groove 78. When the ring is out of position according to 18 and 19 is pushed over the cap (FIG. 20), the annular rib 76 and the annular groove come 78 engaged with each other so that the retaining ring is held firmly on the cap until later removed will. The cap is stretched slightly when it is applied to the container bead 42 /, as is the case for a comparison 19 shows with FIG. 18, and the retaining ring is also stretched when it is pushed onto the cap. The cap edge and the retaining ring thus exert an inward pressure, so that between between the cap and the container 36 / there is strong friction. This friction increases with Vacuum packaging in that the pressure of the outside air presses on the bottom 34 / the cap.

The retaining ring can pass through the locking cap be wound up with a blow of the hammer. To close the containers in filling plants one uses is expediently a device according to FIG. 22. Here, the containers 36 / are from a Conveyor belt 80 carried, which passes under a roller 82. The roller comes along one after the other the retaining rings 48 / all closures 30 / in contact and presses the retaining rings downwards the caps 32 /; here the connecting webs 5.0 / are sheared off.

Another embodiment of a closure according to the invention is illustrated in FIG. Here, too, the same parts have the same reference numbers, but with the addition of the index "g", Mistake. The container to be closed is denoted by 36g and has a cylindrical mouth bead 42 g. The closure 30g comprises the actual closure cap 32g with bottom 34g and rim 38g. The retaining ring 48 g additionally has a flange 84 directed radially inward at its upper end on. This flange engages around the bottom of the cap 32g and limits the sliding of the Retaining ring on the cap.

The closure according to the invention consists of two main parts, namely a closure cap and a retaining ring. The retaining ring is used to hold the .Sealing cap on .the container, and the cap can be used again with or without a retaining ring. The elasticity of the material from which the closure cap is made, allows their frequent reuse without. Danger and permanent deformation; or destruction. The retaining ring can be in one piece with the closure cap, thereby facilitating the initial application of the closure to the container. Here must be the one-piece Connection are sheared off when the closure is applied. In other cases it remains the one-piece connection exist in the form of a flexible band that allows removal of both the retaining ring as well as the cap. In none of the cases described is a tool required for removing the retaining ring or the cap.
