Definitions
- the invention relates to a screw cap made of plastic for screwing onto a thread on a bottle neck of a bottle according to the preamble of patent claim 1.
- This support rib is coupled to the cap base or the closure membrane in such a way that, if the cap base bulges or the sealing washer or closure membrane is in contact with the inside of the closed bottle due to excess pressure, it can be lifted from the edge of the bottle opening and thus automatically vented from the bottle interior.
- a screw cap made of plastic for closing a bottle is known from DE-Al 198 47 001, which does not require a sealing membrane. Inside the screw cap there is a sealing lip with a conical sealing surface which, when the screw cap is screwed on, rests against an outer sealing edge of the circular end face of the bottle mouth.
- recesses are provided which extend from an area which, when the screw cap is screwed on, lies just outside the sealing edge, towards the edge of the sealing lip and are connected to the surroundings. If the base of the screw cap bulges outwards when the internal pressure is increased, the sealing lip slides with its sealing surface on the sealing edge. As soon as the pressure in the bottle and thus the bulge of the bottom is sufficiently large, come the recesses in the area of the sealing edge and thus create a passage for the gases from inside the bottle to the surroundings, so that excess pressure can escape.
- the blow-off time or the blow-off pressure can be set sufficiently precisely.
- the segmentation of the sealing lip also has an advantageous effect.
- the segmentation can be divided into n circular segments with minimal tangential distances or can be provided with distances that have the same or greater length than the lengths of the segments of the sealing lip.
- the tight reclosure of the bottle is achieved after the desired pressure drop.
- FIG. 1 shows a cross section through a screw cap with an inserted sealing membrane before being screwed onto a bottle neck and with a guarantee tape
- FIG. 2 shows an enlarged section of the screw cap according to FIG. 1
- Figure 3 shows a partial cross section through the
- Figure 4 shows a partial cross section through the
- Screw cap and the bottle neck with increased internal pressure (without blowing off) and
- Figure 5 shows a partial cross section through the
- Figure 6 is a bottom view of the cap bottom with segmented sealing lip; left half with a segmentation with incisions, right half with a segmentation with large distances.
- the screw closure 1 shown in FIGS. 1 to 6 comprises a closure base 3 and an adjoining, essentially cylindrical closure jacket 5, on the inside of which threaded sections 7 are formed. Ribs 9 or the like can be provided on the outside of the closure jacket 5, which facilitate the removal of the closure from the neck 11 of a bottle 13 (FIGS. 3 to 5). An originality securing ring 16 can be injection molded onto the lower edge 14 of the screw closure 1 in a known manner.
- the closure jacket 5 has a cylindrical section 15 on the inside, to which a second section 17, which extends in the shape of an arc or a straight line inwards, connects and forms the connection area to the closure bottom.
- the thickness of the wall of the screw closure 1 decreases in the region of the arcuate or straight second section 17. It is much smaller than in the area of the bottom 3.
- a sealing lip 19 adjoins the second section 17, the peripheral surface 21 of which, in the unloaded state, runs essentially cylindrical and can partially lie opposite the section 15 in parallel.
- the sealing lip 19 extends from the apex S 2 of the groove 22 formed by the section 15 and the periphery 21 to a height h-
- the inside flank 23 of the sealing lip 19 initially runs essentially parallel to the periphery 21 and then passes into a step P, which acts as a drying edge, which leads to a thickening and the sealing lip 19 up to the root 29 gives a higher rigidity.
- the stage P is at the height h 2 (FIG. 1).
- the radially inner flank 25 of the sealing lip 19 which adjoins the step P runs radially slightly inwardly inclined up to the height h 3 and ends there at the apex S ⁇ (see FIG. 1).
- the sealing lip 19 can form a circumferential ring ( Figures 1 and 2) or be divided into a plurality of circular ring segments (FIG. 6).
- the circumferential sealing lip 19 can be divided into a plurality of segments 19' only by cuts 19 '' (left half of FIG. 6), and on the other hand, there can be distances between the segments 19 ' be formed, whose length A corresponds to the length B of the segments 19 'or is greater (right half of Figure 6).
- the segments 19 'and the distances each comprise 60 angular degrees or 45 angular degrees.
- the reduction in the thickness of the base 3 in the region of at least the apex S- forms an elastic zone which, when the base 3 bulges out, causes a relative movement of the sealing lip 19 to be described later.
- the second downward wall 27 of the groove-shaped space 28 under the apex S- ends approximately at the height h 2 and forms the outer flank of a rib-shaped spacer 31, which comes to rest over the end face 33 of the bottle neck 11 when the screw cap 1 is placed on the bottle 13.
- a further elastic spacer 35 can be arranged in a rib-shaped manner concentric with the spacer 31.
- the closure bottom 3 can laterally of the radially inside lying spacer 35 also have a circumferential groove 36, which leads to a local reduction in the thickness of the closure bottom.
- the thickness is preferably the sealing membrane 37 between the periphery and the contact area with the elastic spacer 35 greater than the thickness d 2 in the central area.
- the closure membrane 37 it is possible to design the closure membrane 37 as an annular surface which extends essentially from the thread 7 to radially within the inner spacer 35.
- the periphery 38 of the closure membrane 37 lies outside the peripheral surface 21 of the sealing lip 19, so that the apex 24 of the latter abuts the closure membrane 37 briefly in a line shape before the screw closure
- the pressure inside the bottle 13 rises above a predetermined level as a result of cooking or excessive heating of the bottle contents, this leads to a domed bulging of the closure base 3 (FIG. 4).
- the bulging of the closure base 3 is additionally promoted by the at least one annular thinning of the cap base 3 in the region of the apex S T of the incision or space 28 between the sealing lip 19 and the spacer 31. This means that the sealing lip 19 itself moves slightly axially upwards when the base 3 bulges out and there is a radially inward displacement of the point Q in the root region 29. This causes the sealing lip 19 to tilt about the point P at the step 23.
- This translational movement reduces the pressure of the sealing lip 19 on the edge region 39 of the bottle neck 11.
- the pressure of the closure membrane 37 on the central region of the end face 33 of the bottle neck 11 is also reduced and enables this Blowing off gas and thereby reducing the overpressure inside the bottle.
- the blowing off is additionally promoted by the deflection of the sealing membrane 37 into the space between the sealing lip 19 and the spacer 31 (cf. FIG. 5).
