Abstract
Abstract The screw cap (1) possesses an internal thread (4), on the cap base (21 orientated end (7) of which a brake element (5) is arranged, which lies in the helical line of the external thread (9). The start (10) of the external thread overrides this brake element when the cap is screwed on, whereby a braking effect and a imitation of the screwing movement will ensue.

~ S f~ ~ ) ~''i -' 51 ~1 n6.03.90~ ~ V
Crown Cork A5, CH-4153 Reinach Scre~ Cap made o~ Plastics Material The invention concerns a screw cap made from plastic according to the preaml~le of claim 1. These types of screw caps are manufactured in very large numbers by the in~ ion molding process and are used to close off containers of the most varied kinds. Screw caps made of plast1c have ~ound an application mainly in the refreshment drinks branch, where the screw caps are screwed automatically on~o the filled b~Les on rapidly moving filling ]ines~
.
A problem with conventional screw caps occurs in that they must be screwed on with a definite application of torque, in order to ensure a sealed gt. Thereby, the screw movement is normally limited, since the bott~le opening comes into contact with the base of the screw cap. The danger thus exists that the cap is screwed on with excessive torque, so that subsequently it can hard]y be manua~ly unscrewed. Overwinding of the threads can also occur in certain cases, since the bc~ttle openings, especially in the case of glass bottles, can exhibit large variations of tolerance.
It is therefore a purpose of the invention to design the screw caps of the type mentioned in the introduc~ion so thal: the screw-on movement is no longer limited, or no longer exclusively ~imited, by the base of the screw cap, and so that screwing on o~ the cap wi~h too great a torque onto the container open~ng can be prevented. This purpose is achieved, according to the invention, with a screw cap exhib;ting the character~stics of cla~m 1.
The 1: ra~ce element, arranged in the region of the helical line of theexternal thread of the container, arrests the screwing on procedure wi~hout the opening of the container, with full torque appLicatLon, at the same time coming into contact w~th the screw cap base. When the external thread makes contact wi~:h the brake element9 the screw-on force is transformed into a radial ~orce component, since the external , , `
thread has a tendency to override the brake element and with that to be radially displaced ou-twards.
Depending on the design of t:he brake element and the elastic properties of the material, the rest position of the screw cap can be retarded. With that, it is especially advantageous if the brake element possesses an override surface which runs approxirnately parallel to the middle axis of the screw cap. Apart from that, the override surface can be inclined at an angle runn~g through the middle axis ol' the screw cap. The override surface is thus formed like a ramp, onto which the external thread ascends with increasing radial tension.
The brake element can be integrated into the internal thread or it can be formed separately from the internal thread. The braking element can also possess a profile which is formed as a thread aank for the internal thread. The brake element obtains an additional function in this way. ~rhis function can be ex~ended if the screw cap possesses one or more support ribs near the screw cap base to hold an inserted sealing disk in place, and if the braking element possesses a prc~ile that runs in the plane of the support ribs. Thus, a part of the sealing disk rests upon the brake element.
The previously mentioned multi-function of the brake element can thus be especially easily achieved if, in plan, it possesses the shape of a wedge, which extends through a sector of at least 90 degrees. With that, the override surface is arranged on the wide end of the wedge which must possess a dei~inite minimum width in order that the start of the external thread always strikes -the brake element.
A version of the invention is dep~c ted ~n the drawings, and is more exac~y described in the following section. Namely:
igure 1. a cross-section through a screw cap according to the invention, igure 2. a cross-section through a screw cap, screwed onto a container opening according to Figure 1, ' '' ~'"'' ~ . .

A screw cap I is dep~cted in Figure 1 wl~::h comprises in principle a cap base 2 and an adiacent, somewhat cylindrical cap wall 3. The screw cap is rounded off in the transitional area 5 between the cap wall 3 and the cap base 2. The internal thread 4 is arranged ~n the inside of the screw cap wall, which possesses approximately l ~ /2 turns. These are mterrupted by air release slots l 1, which allow a rapid release of pressure when the cap is unscrewed if an over-pressure e~usts within the container.
Support ribs 13 are arranged on the cap wall 3 near the screw cap base 2 vr in the transitional area 5~ These support ribs hold a sealing disk 12, made from an elastic material. As can be observed in figure

A screw cap I is dep~cted in Figure 1 wl~::h comprises in principle a cap base 2 and an adiacent, somewhat cylindrical cap wall 3. The screw cap is rounded off in the transitional area 5 between the cap wall 3 and the cap base 2. The internal thread 4 is arranged ~n the inside of the screw cap wall, which possesses approximately l ~ /2 turns. These are mterrupted by air release slots l 1, which allow a rapid release of pressure when the cap is unscrewed if an over-pressure e~usts within the container.
Support ribs 13 are arranged on the cap wall 3 near the screw cap base 2 vr in the transitional area 5~ These support ribs hold a sealing disk 12, made from an elastic material. As can be observed in figure
2, this sealing disk is displaced upwards when the cap is screwed on, whereby it comes to lie as a seal around the area of the opening.
A brake element 15 is arranged at the end 7 of the intexnal thread 4, which is formed slightly less deeply than the i~lanks of the internal thread 4. As shown in figure 4, the brake element is formed in plan as an extended wedge. It is not connected to the thread end 7, but starts im mediately after a pressure release slot l 1. The brake element ., . : . .
.. : .. ' 7~3~
extends through the sector A to B, through slightly more than ~ 80 degrees .
The brake element has an override surface 16 which is inclined through the ang1e Alpha to a plane running through the middle ax~s of the screw cap, as can be seen in figure 3. The override surface otherwise runs parallel, however, to the middle axis, so that when the start of the thread l0 overrides it a force component m the direction X ensues~
The brake element possesses a profile ~ 4 which is inclined in the helix angle of the ~nternal thread 4 and which in practice performs the function of a thread flank. On the other hand the brake element also has another profile 15, which lies in the plane of the support ribs ~ 3.
Thus the pro~ile 15 forms a continuation of the support ribs l 3, on which the sealing disk 12 lies. The support nbs ~ 3 are mterrupted at the pressure release slots 1~, to ensure optimal pxessure release. It would also be conceivable to prov~de a singlet continuous, support rib.
The wedge shaped brake element 6 depicted in ~igure 4 has evidently a multi-function, in that i~ serves as a mechanical stop for the external thread, as a thread flank, and as a protection shoulder for the sealing disk. This configuration is also particularly advantageous from the technical point of view of injec~on casting and tooling, and allows itself to d~stort easily.
Evidently the brake element 6 must not ~f nescessity possess the wedge shape shown in this version. Closure caps with al~ernative sealing systems can ~ispense w~th the profile 15 or adopt another relative position, without problems. The configuration of he brake element must in every case be such that it always lies in the region of i~he h~lical line for the external thread.
The figures 5 and 6 show alternative configurations of -the brake element. With that, the radial depth can be approxirnat~ly the same as with the version depicted according to the figures 1 to 4.

According to figure 5, the brake element 6 is formed as one part, connected with the end 7 of the internal thread and extends like a vane into the heli~al line of the external thread. Th~ start 10 of the external thread likewlse strikes the brake element head-on. In the case of the version according to figure 6, the brake element is ll-shaped and arranged fully separately. The lower limb could, however, theoretically form the continuation of the internal thr~ad. The s~t 10 of the external thread does not strike head-on here, but comes into contact with both surfaces of the braking element.
In the case o~ the version depicted in figure 7, the brake element 6 isformed as a rib, wh~ch can extend over the entire circumference of the cap wall 3, or also only through a certain sector. When the cap is screwed on, the underside 17 of the rib makes contact with the start o~ the external thread 9. As opposed to the previously descnbed radiaLly acting override surface ~ 6, the underside i 7 exerts an axial braking force. The rib could also serve, for example, as a reinforcement o the transitional area o~ cap base 2 and cap wall 3.
An alternative example of a screw cap accorcling to the invention is depicted in figures 8 and 9. In place of an inserted sealing disk, the screw cap 1 possesses an o]ive formed inner seal 21 on the screw cap base 2, which is pressed mto the b~le opening when the cap is screwed on. A removeable guarantee strip 18 is arranged on the lower edge of the screw cap which is provided with at least one retention element. A surrounding bead 19 is provided at the contail~er opening 8, under which the retention element 20 engages when the screw cap is screwed on for the first time. When the cap is unscrewed for the first t~me, the guarantee strip is either t~tally or partly separated from the lower edge o~ the cap, so that the inili~l opening oE the screw cap will be indicated. This type of guarantee strip is already known to the specia~ist, whereby the retention element can possess different shapes, for example cams, tongues, beads etc.
The brake element: 6 is now particularly advantayeously so arranged that when the cap is screwed on for the first time the braking e~fect will take ef~ect immediately after the engagement of the retention .

Depending on the nature of the retention element, it can be significant for the function of the guarantee ~llip if the guarantee strip does not exceed a definite relative posi~ion to the bead l9. The brake element 6 could, however, be so arranged that the braking effect is already applied be~ore the engagement of the retention element, and that the engagement position will just have been reached when the braking procedure is complete, therefore when the screw cap is at rest.
In the version according to figures 8 and 9 the braking element comprises a rib or a thickening in the transitional area 5 of the cap.
The rib extends through an angle Beta of approximately 75 degrees.
The inner radius r of the rib is less than half of the diameter d of the external thread 9. With that, the start 10 of the external thread strikes the override surface 16, presses the rib 6 radia~ly outwards and causes the screw cap to come to rest through higher fric~n a~er a de~inite arc length.
Naturally the screw cap according to figures l to 3 can be provided with a guarantee strip according to figure 8.
