In the production of closure caps for the described ones designed according to the invention. Container is the Closure cap 26 with a seal 68 made of a plastomer or elastomeric material. This can be a vinyl plastosol, for example. The formation of the seal can be carried out according to known techniques. The union of the ring 24 with the closure cap 26 takes place by the threads 60 of the closure cap 26 with the threaded ribs 52 on the ring 24 in connection brought and the cap 26 is rotated until the rolled edge 62 the annular groove on the lower part 48 of the ring 24 touches. From that moment on, the cap 26 is firmly attached to the ring 24, although the seal 68 is still in the unloaded, uncompressed state because the closure cap 26 and the ring 24 is not yet connected to the container 22 After the container 22 is provided with its Ptillgut and is to be closed, the Unit or combination of cap and ring according to pressed down over the container 22 until the cooperating surfaces 44,66,42,64 touch each other and as a result, the ring is held against axial movement is. The recesses 72 in the ring 24 are normally not arranged in register with the elevations 40, because there is a lack of facilities to put the closure cap and the ring in the correct position relative to the container 22 Able to compress ^ keqn ^ al ^^ dae elevations 40 and

however, if the recesses 72 happen to be in alignment with one another, then the recesses 72 take the Ribs 40 on. Both the engagement of rib 4o and recess 72 in one another and the friction between however, the ring 24 and the container 22 prevent any after the ring 24 is placed on the container 22 further relative rotation between ring and container,

because the ribs 40 in the inner surface 38 of the ring ^

24 are buried.

The ribs 40 are formed in accordance with the invention Containers are not absolutely necessary, but they can advantageously be used for sliding movements between the container 22 and the ring 24 to prevent.

Instead of ribs 40, other devices j

can be used in order to avoid relative rotation of the ring 24.

Another aspect of the: designed according to the invention The container consists in that the recesses 72 can serve as attack devices or the like, which allow a plague of the ring 24 against rotation while the closure cap 26 is in the Closing position is rotated. In this turn

the cap can then be held in place relative to the ring by, for example, a simple nub or elevation on the outer surface of one or the thread turns 52 27 is provided. This in turn is in a recess 29 of the complementary cap when the cap is screwed on Nut thread turn of the cap was added. Due to the mutual engagement of the knob 27 and the recess the closure cap 26 continues to be held firmly in place relative to the ring 24 during handling.

After the ring is striped 24 through the container 22 ^'lx content particularly a "heat treatment in autoclaves, boilers or the like, the application of pressure sufficient size can be further treated. For cooking, sterilization or the like. Exposed. Causes the ring 24 enters the position shown in FIG. 3, so that the seal 28 is resiliently deformed and assumes the shape shown in FIG.

The ring 24 is _: although shown in a shape in which its surfaces 44,64 rest in a tight, close fit on opposing surfaces 42,66 of the container 22, while the container 22 at the opening end 30 has a tapered shape. As a result, a hermetically tight seal is also obtained when there is a certain axial play between the said opposing surfaces, because as a result

the conical shape of the container opening end has a corresponding effect on the ring 24

Any friction that occurs between the inner surface 38 of the ring 24 and the outer surface 36 of the container 22 increases the effect or the resistance that a Relative rotation of the ring with respect to the container is opposite.

4 and 6 show a modified form of the container designed according to the invention. In this container, too, a cap 26a with a cap edge 58a and a rolled edge 62a is provided, which corresponds to the shape according to FIGS Container is held. The ring 24a lies above a lower annular rib 32a. In an upward direction from the outer surface 50a of the ring 24a and formed in one piece with it, a display device 74a is provided which has a resiliently downwardly pretensioned, inwardly directed part 76a which engages over the upper part of the rolled edge 62a. In FIGS. 5 and 6, the starting position of the display device 74a is shown. In this position, the display device 74a can be recognized by the viewer or it is visible. However, when the cap 26a is twisted and removed from the container 22a

is unscrewed and screwed on again at the connection, ³ then the extension 76 moves downward due to the inherent elasticity and thus prevents any further access to the annular groove in the lower part 48 of the ring 2'4ä (Pig. 1). The attempted reattachment of the closure cap 26a is immediately recognizable because the display device 74a prevents the closure cap 26a from being exactly repositioned in the starting position. One or more display devices 74a are normally provided in order to make the attempt more difficult to put the cap back on without the display device allowing this to be recognized; further other display devices, for example in the form of a seal i, can be used instead of or in addition to the embodiment described.

The iig. Fig. 7 shows another form of tamper-evident clasp. In this embodiment, the display device 74b is designed in such a way that it extends in an upward direction from the outer surface 50b of the ring 40b, but is connected to the cover 24b 'via a narrow, tearable neck zone 78b ^; to which in turn a part 80b engaging in the closure cap is connected. The connection of the part 80b connected to the cap or engaging in the cap takes place by means of an adhesive application 82bj by means of which the part 80b is connected to the cap edge 58b. Eö can be pressure-sensitive

heat-activated, bite-melting or other adhesives can be used that provide a tight fit or a tight connection between the part 80b and the Ensure sealing cap 26b. This connection must be stronger and more resistant than the severable one Neck part 78b can be designed so that a rotation of the closure cap 26b leads to tearing of the seal or severing of the neck part 7öb and the user immediately can determine that the guarantee lock has broken. Notes that refer to this guarantee lock take can be attached to the container to make the user aware of this fact.

In Fig. 9, another embodiment is one Ring 24c shown. In this exemplary embodiment, too, the ring 24c can be equipped with a lower part 48c be, which serves an opposite of the cap as a support, and there can be threads 52c for Plague hold the closure cap serve. This ring 24c also has a downwardly facing surface 64c and an upwardly facing end face 44c which come into contact with the corresponding mating surfaces on the container. However, the ring 24c is additionally provided with an upper part 84c, which merges over a radius 86c into the outer surface 46c of the ring 24c. A Edge part 88c located radially inside the upper part 84c adjoins it. One made of rubber or rubbery

Material existing additional seal in the form of a Insert seal part 90c, which is dovetail-shaped in cross section, is on an inner surface 92c of the upper part 84c arranged to be within the sealing outside area of the ring to create a further sealing zone for reasons to be described. The seal 90c. Is although shown as being made of rubber or rubber-like material, it should be noted that other elastomeric materials as well or plastomeric materials such as vinyl plastisols can be used, which are also used for the seal 68 can be applied.

The arrangement and use of the ring 24c according to FIG is the same as the ring shown in Figures 1-3. The basic differences are shown the Ausführungsforro of the ring shown in Fig. 9 and the previously described is that the closure cap in both a lateral zone and in.einer Zone in the end face sealing with the ring in Contact can occur. A seal between the ring and the. Container, which in addition to sealing is provided, which is given by the mechanical seat or its shrinkage, is by the ring or the seal 90c is achieved so as to prevent leakage or ingress of liquids and / or gases along the annular container zone is avoided.

Another possible embodiment of the ^ ring shows Fig. Ί0. The ring 24d shown in FIG. 10 has outer threads 52d, a lower part 48d and an upper part 84d, which communicates with the outer surfaces via a radius 86d, while extending radially inward of an inner edge part 88d is followed by a second cap, but preferably cover part 94d, which passes through • a line of weakness 96d is defined. A pull handle 98d is attached to this cover part 94d. At the In use, an outer cap is placed over the ring 24d and the two are attached as a unit placed on top of a container. The removal of the outer cap does not now lead immediately to open the container, but rather exposes the second closure cap or the cover part 94d, see above that the tear part defined by the line of weakness 96d becomes accessible. Different shapes and configurations of the line of weakness 96d can be used to produce certain forms of tear-away parts. The cover part 94d can, for example, also have several small openings instead of a tear-open part Have, so that, for example, a spreader lid or the like. Can be created.

The ring 24d according to FIG. 10 is without that shown in FIG Seal 90c shown. This embodiment

can be used if the requirements are particularly high placed on the tight seal between the ring and the container in the area of the upper end face of the container will. In the embodiment according to Pig. 10 can, however, if necessary, also with a seal 90c can be worked according to FIG.

An essential aspect of the container designed according to the invention is that the used Ring with its intermediate surfaces creates seals or sealing zones that seal on all sides Ensure sealing cap in relation to the container.

Since, however, the acting between the container and the cap If seals already fulfill this purpose, such a seal is not absolutely necessary. Another essential aspect of the present invention is that the ring and the closure cap can be combined separately from the container and then viewed as a unit. You can Shipped or put in stock in this condition and transported for later use. It This results in a considerable reduction in the risk that the threads on container closure ends the containers are damaged during transport; because the threads themselves are now on the Ring and are there in turn by the one above it

The edge of the cap is protected from damage. Naturally, there is still damage under certain circumstances possible, although due to the design there is hardly any risk of endangering the sealing of the container is.

Another advantage of the container designed according to the invention is that one or more display devices are provided after / _rt a guarantee lock works. These measures or guarantee locking effect occurs even before transport. That, in turn, means a considerable amount of relief for the bottling industry; because this needs now not to deal with the formation of guarantee closures, but rather sets manufactured, the guarantee closure already owning units on the relevant container.

Another essential aspect of the invention trained 3ehäiters consists in that / ic bottom part of the ring a groove 4fc is provided, which two things Purposes. First, it limits the downward possible movement of the cap over the Ring before ring and cap are placed on the container as a unit. It also becomes a dense Seat created between ring and cap.

009 6 39/1240

There is also a not inconsiderable stiffening the unit ring and sealing cap, which is advantageous if the one consisting of sealing cap and ring Unit is placed on the container. The tight, snug fit between the lower part of the ring and the cap rim of the closure cap which is achieved in this way leads to a substantial reduction the possibility of unwanted inclusions of certain bacteria and insects in the area of the cap edge of the Sealing cap.

Although normally with the container designed according to the invention any materials can be used, because the invention is not material-dependent, it is recommended if the ring is made of a relatively stiff thermoplastic material. The body of the cap is typically made from metal, although it is also made from more rigid, thermoset or thermoplastic materials. It is particularly advantageous, although not necessary, if the container is made of glass. On the other hand, however, it can also be made of plastic and for example Possess Piaschenform. The guarantee lock or those used to form the guarantee lock Devices may suitably be made of plastic when made in one piece with the ring

or they can be applied later
and form "existing units" of metal or plastic which are connected to the "other components concerned" by gluing, welding or the like.

From the foregoing it can be seen that the new training of the container or the use of a ring which is separate from the container and can be connected to it Benefits can be achieved.
