Description

1301530 (1) VENTURE DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a closure device for a container, particularly a bottle, comprising an upper cover panel and a circumferential hoop adjacent to the cover panel on the outer edge Or a rim, wherein a sealing insert or liner is disposed on the bottom side of the cover panel, the cover panel having a circumferential contour seal along the outer perimeter. [Prior Art] This closure device is also known as a (closed) lid or (closed) bottle cap. The closure device within the scope of the invention is in particular a bottle closure device which can be made, for example, as a crown closure closure or a tear closure closure. These closures are sealed to the container by a collapse operation. In both cases, the cover panel is inserted over the closure of the contour seal onto the bottle against the top of the bottle under the seal of the closure. A circumferential band or hoop forming a cylindrical closed rim surrounds the neck bead after sealing, and the lower portion of the rim provides a strong grip underneath the bead ring. In a specific embodiment, such as a crown cap closure device, the rim is provided with the common crown cap punch or tooth and has a rib that abuts against and slightly below the crimp ring. And give the appropriate tight grip. Crown Cap The closure means a standard crown cap that will be opened with a tool, and a twisted crown cap that is turned by hand or bent with a tool like a standard crown cap. In the case of a tear-off container closure, the rim is collapsed under the hem ring and provides a tear-off strip through which the tear-off strip is passed and the rim is The scribe line defines 'where the tear-off strip continues to act as a tab protruding beyond the rim of the hood, and a pull-out member, such as a pull tab

-4- (2) 1301530 is attached to this tab. In a wide range of specific embodiments, such as a crown cap closure and a tear off closure, a bottle closure is known. A constant problem is the treatment of carbon dioxide-containing liquids in bottles. For example, to ensure a high and constant quality of the carbonated material, the bottles must be tightly closed with the closure provided to eliminate leakage from the carbonization process. In this case, there is a problem that a considerable internal pressure φ can occur in a bottle filled with a carbon dioxide-containing liquid. This high internal pressure can occur particularly when the filled and closed bottle is exposed to high temperatures and/or severe movements, such as during transport. This can cause considerable problems because there is a risk of explosion or bursting of the bottles at this high pressure, whether or not the bottles are made of glass or plastic. There is a considerable risk of injury associated with the user or a third party in the vicinity. In the case of a closure device that is sealed by collapse, such as a crown cap closure device, the same principle applies, with which the closure device strongly leaves the top of the bottle by this high internal pressure. These risks are barely acceptable for the manufacturer of the bottle closure and for the beverage manufacturer or bottler because of any liability risks associated with it. However, despite this, 'since the beverage is exposed to such pressure during the heat sterilization process', it must be considered that the filled and closed bottle must be able to easily withstand a pressure of 6 bar without any significant pressure. loss. For this reason, crown caps and other closure devices are made to remain firmly on top of the bottle under a pressure of less than 1 bar. Thus, there is essentially a need to establish a bottle closure that minimizes the problems described and makes it possible to release pressure via the closure -5-(3) 1301530 device at such high internal pressures. In this regard, it is known to use a seal made of a special tough polyvinyl chloride or the like, wherein these soft elastic polyvinyl chloride seals make it possible to release pressure under high pressure. However, for various reasons, PVC will no longer be used as a sealing material for foods, especially beverages. However, PVC-free sealing materials which have a relatively high polymer density for practical use have the disadvantage that they have less elasticity or toughness, and that the release of pressure cannot be ensured at this high internal pressure and then "Reseal" during the pressure drop. The need to release the pressure for bottles sealed with crown caps has been recognized in 1956. A special lining frame made of a soft elastic sealing material is combined with a closure made of ductile metal to cause the overlying panel to bulge or skyrocket (see U.S. Patent No. 2,397,724). In a tear-off container closure device, which is known in the case of the strontium carbonate material, a release is provided by the tear strip, or the connecting section, or the region of the pull-out member attached thereto. The pressure valve makes the release of pressure possible, wherein the adhesion or clamping of the lid to the bottle is reduced in this area (see German Patent No. 3 7 3 7 4 6 7 A 1 or US Patent No. 4 768 667). This measure has been proven to be effective at all. However, they are based on a soft elastic linear material similar to that of polychloroethylene, and are not applicable to other types of closure devices, such as crown cap closures. U.S. Patent No. 2003/0 1 2742 1 A1 discloses a vented plastic closure device which includes a plastic cover having a top wall portion and an annular rim portion. The rim portion includes at least one internal threaded structure such that the closure device is formed as a nut to be screwed onto the threaded container. In order to perform the desired sealing fit with a related container, the vented plastic closure (4) 1301530 includes a disc-shaped sealing liner, the inner side surface of the wall portion. The dense chamber is compression molded in the container associated with the outer closure cover to perform a so-called "JI", the sealing liner comprising a hanging ring substantially upwardly facing downward and outwardly sealed by an inner side of the top wall portion The lining support member is positioned inwardly and substantially parallel to the support surface. The lining support member and the sealing bead are associated with the desired reduction in the number of closure devices. Furthermore, the outer closure lid side surface hangs the positive terminating element. The side is positioned radially. By eliminating the problem with the $off, the closure device should be advantageous. British Patent No. 960 296 The outer edge of the thin, sheet-like plastic material has an outer crimped milk bottle. The lid closure device of the neck of British Patent No. 958 417 A, which is molded into a unitary structure.

U.S. Patent No. 3,741,423 A is positioned adjacent to the top seal liner of the closed lid to be within the manufacturing period of the closure device, and the tie frame is configured to seal with the crotch portion/side. Having a surface, the outer closure cover includes an annular seal bead of a lining of the annular lining support member, and the lining of the sealing surface of the lining seals the sealing rim of the sealing lining to the surface of the container. And the use of the relatively expensive lining material comprising the inner end member of the top wall portion can be over-applied in the outer casing of the sealing lining. The internal gas pressure is removed and the arranging is very special. An aerosol bottle is molded for application to the top of the crucible. A closure for a bottle or similar container is made up of a synthetic thermoplastic that is used to produce a liquid like bleach to reveal a special type of closure ( 5) 1301530 for a food product to be kept under vacuum. The closure lid comprises an annular container engaging gasket applied to a plurality of portions of the lid rim Above the portion, and extending inwardly over the bottom cap beyond the inner edge of the edge of the container. When the lid is applied to the mouth line of the container, the rim portion of the gasket is created in the glass bottle line One of the portions bulges inwardly into a plurality of recesses, thereby forming a cover-like projection portion like a handle to leave the closed cover on the container. SUMMARY OF THE INVENTION The object of the present invention is to provide a The closure device of the container, in particular the bottle closure device, is not only generally used for conventional neck crimping and manufacturing and sealing systems, but also, when it is reached, a predetermined internal pressure is reached. It is possible to achieve a specific pressure release and subsequent problem-free reclosing. To solve this problem, the present invention defines and teaches that the upper cover panel is used in a conventional closure device, particularly a bottle. The bottom side (facing the sealing insert) has at least one projection, such as embossing, extending over at least a predefined angular region of the projection at the contour In or near the contour seal, the seal member protrudes and interacts with it to form an exhaust valve. According to the invention, the upper cover panel has an annular sealing lining on its bottom side, which is peripherally located There is an outer protruding portion, the inner side of the protruding portion is adjacent to a lower and wider ring, and when combined, constitutes a lining structure ("contour seal") and is designed to be compatible with one of the upper cover panels Defining the embossing, punching or pattern interaction to form an exhaust valve. -8- (6) (6) Starting from the knowledge confirmed by the experiment, the bottom side protruding part, for example with the contour punching, The mold groove, and the function of forming the seal with the contour. By selecting a suitable combination, the predetermined reduction pressure allowed under a predetermined internal pressure of 10 bar can be automatically and relatedly The risk can be such that the shape, height and width of the quality of the filled beverage are required to be released at a predetermined internal pressure level, and the problem can be re-closed or the solution according to the present invention is torn. The action means the same manner as the formula engagement. The bottle of the scribe line provided by the tear-off closure device can use the neck-type bottle type of all conventional bottle neck standards is valid), Japan and similar standards, all standards or structures. The bottles may be made of glass or may have a "step-like" cross-section that is tied to an outer first (lip) sealing ring and or sealing surface in cross section, wherein the outer sealing is at a large height and / Or a smaller width. In this case, the present invention may provide a closure device between the contour seal and the embossing, for example, if the cover panel is provided with a region of a seal member and the embossing and sealing members interact with each other. , for example, the release of pressure at 7 and the sealing of φ at 2 bar. The damages used for the initial description are eliminated in a cheap way without any loss. The position and combination of the embossing causes the closure to be re-sealed at a pressure and at a predetermined pressure. In this case, the performance of the closure device in the root closure device with the crown cap closure is not affected. There is no need to modify the neck of the ® traditional standard bottle here. This is true for seals made in Europe, the United States (GPI with a slightly different neck profile made of plastic. The "contour seal" face. In a preferred embodiment, it is made substantially L-shaped and has a The inner second (flat) seal ring has a -9-(7) 1301530 than the inner seal ring. In this case, the invention begins with this knowledge, that is, the interaction with the protruding portion or embossing according to the present invention. The contour seal is such that it is possible to achieve a specific indication and particularly reproducible pressure release. The seals, which are known empirically, have a C-shaped lining cross section which generally comprises a high outer lip seal ring, a low And a slightly flat intermediate sealing surface, and a high lip inner sealing ring, and does not provide any specific pressure release below 10 bar. It is particularly important with respect to the present invention that the contour seal follows the Φ pressure When a venting or venting valve is formed, there is no longer any need to accept or provide any bulging or even ascending of the closure covering the panel, which operation does not have this overlying Any bulging or ascending of the sheet. According to one embodiment of the invention, the projection or embossing is formed as a circumferential step portion and has a side that is steeply descending downwardly to form, for example, the cover panel One of the lower central sheets. This step portion can be made, for example, as an entire circumferential step portion and has exactly the same radius, and when viewed from above, forms a circular cover central region. It should be understood that I is this step. The step portion is itself radially interposed with the contour seal and forms a valve member. The desired exhaust effect can be adjusted by tuning various parameters. In a modified embodiment, the circumferential portion The step portion may have sections of a plurality of step portions having different radii, each segment extending over a predetermined angled region. Thus, the step portion is configured to be above a predetermined circumferential region, and Here, the contour seal has a stronger exhaust valve function radius, and the other regions of the step portion are disposed in a function that only has a small valve forming function. In this way, the desired pressure release or exhaust effect can be further specified by selecting the corresponding circumferential regions. -10- (8) 1301530 The radius of the step portion or at least the step portion can be Less than or equal to or slightly greater than the outer radius of the contour seal, and/or greater than or equal to or slightly less than the inner radius of the contour seal, such that the radius of the step portion may be greater than the inner radius of the inner seal ring Any size up to the outer radius of the outer seal ring. Further, an exhaust valve formed by the interaction between the contour seal and the embossing may be given a form that extends to a greater than the contour seal An outer radius or a radius less than an inner radius of the contour seal. However, the step portion or step portion is sufficiently close to the contour seal to interact with the seal ring or the seal rings, and Thereby affecting the sealing property of the contour seal, the side angle of the step portion or the step portion of the step relative to the horizontal plane or the side of the upper cover panel For example, 40 degrees to 90 degrees, for example, 60 degrees to 80 degrees. The choice at this angle also provides a sensitive parameter for setting the desired venting function. By a steep angle of about 90 degrees, for example 80 degrees, the seal can be particularly strongly affected and a stronger exhaust valve effect can be achieved. However, it is also possible to work at a flat angle of 10 to 40 degrees. In another embodiment, the protruding portion or embossing is not made as a (single) step portion, but is formed as a groove or channel of a predetermined width and height extending around or extending at a predetermined Above the angled area, there is an outer side that is lowered toward the center of the lid and an inner side that rises toward the center of the lid. The raised inner side can be directly adjacent to the lowered outer side. However, it also appears to be possible to provide a flat base area between the sides. Viewed from above, the groove can be made into a

-11 - (9) 1301530 A toroidal, full circumferential groove extending over the total area of the cover and thus over the full angle of 3 to 60 degrees. However, it is also possible to provide a plurality of trenches or trench segments, each trench extending only over a limited predetermined angular region. In a particular embodiment having a plurality of trenches or trench segments, all of the trenches can be disposed on the same radius. However, it is also possible to arrange the grooves or groove segments at least partially at different radii. The grooves or groove segments emboss into the overlying cover during manufacture of the closure. However, the present invention also encompasses a specific embodiment wherein the protruding portion is formed as a protruding portion that is attached to or molded into the bottom side of the upper cover panel. There is likewise a possible architecture described for this trench. However, specific embodiments having embossed grooves or step portions are all distinguished by their particularly simple manufacturing. In a particular embodiment having a circumferential or partial circumferential groove or projection, there are numerous possibilities for effecting the valve formation effect by setting the desired parameters. Thus, the angle of inclination of the descending side relative to the horizontal plane and/or the angle of inclination of the rising side relative to the horizontal plane may range from 40 degrees to 90 degrees, such as from 60 degrees to 80 degrees. The tilt angle can also be 5 degrees to 40 degrees, such as 10 degrees to 40 degrees. The grooves or the projections may be made symmetrically or asymmetrically, i.e., have identical or unequal inclination angles. Thus, it may be appropriate if the outer side is formed as a steep side and the inner side is made as a flat side, or vice versa. The desired degassing effect can be sensitively affected by also selecting the appropriate radius of the groove or groove section relative to the contour seal. As such, the present invention provides that the outer radius and/or inner radius of the trench or at least one trench segment is less than or equal to the outer radius of the contour seal, and/or greater than or equal to -12-(10) 1301530. The internal radius of the seal. As such, the grooves or groove segments are at least partially disposed in the region of the contour seal. They may be completely disposed in the region of the outer sealing ring or may also be completely disposed in the region of the inner sealing ring. Furthermore, the groove or a groove section may also extend from the region of the outer seal ring into the region of the inner seal ring. Furthermore, the inner radius and/or outer radius of the groove is slightly less than the inner radius of the contour seal, or the outer radius and/or inner radius of the groove is slightly larger than the outer radius of the contour seal. However, the groove or at least one of the groove segments must be sufficiently close to the contour seal to interact with the contour seal and thereby affect the sealing properties of the contour seal. The width of the groove is preferably from 1 mm to 4 mm, for example from 1 mm to 3 mm. The height of the groove or step portion may be from 0.1 mm to 0.8 mm, for example from 0.2 mm to 0.6 mm. In accordance with the present invention, the cover panel forming the closure device with the rim or hoop attached thereto is made of metal, such as tinplate, aluminum or tin-free steel, and suitable alloys thereof with other metals. The sealing insert or liner assigned to the underside of the cover panel is preferably formed as a single component and made of plastic. The sealing insert or liner is preferably made of polyethylene (PE), such as low molecular density P E (L D P E ) or a modified material thereof, with or without an adsorbent. In any case, it is preferred to use a PVC-free plastic. The thickness of the (metal) closed casing (covering the panel and the rim) is 0.15 mm to 0.25 mm, for example 0.17 mm to 0.24 mm, preferably 〇17 mm to 0.21 mm. As has been explained, the closure device can be made as a tear-off closure or a curved closure crown g. The -13- (11) 1301530 closure device has a diameter of about 18 mm to 45 mm. The crown cap closure is typically made to have a diameter of 26 mm to 27 mm. The sealing insert within the scope of the present invention is preferably formed as a full lining and has a circumferential contour seal on the outer side and a low center region that does not have a sealing function itself. The liners are preferably formed by direct compression molding of a prefabricated closure having the embossing and molded onto the underside of the upper cover panel. However, it is also possible to manufacture the sealing insert in a separate production step, for example by stamping out an extruded plastic sheet and then fixing, for example, glue to the bottom side of the upper cover panel. [Embodiment]

These panels show closures for the opening of bottles or other containers. Figure 1 shows the basic construction of a bottle closure device in a particular embodiment of a tear-off closure device. The closure device comprises an upper, circular cover panel 1 adjoining a substantially cylindrical hoop or rim 2 on the outside thereof, the rim surrounding the neck 3 of the bottle during sealing and at the neck of the bottle One of the curling edges 4 or the underside of the flange is clamped. On the underside of the cover panel is a seal liner 5 (not visible in Figure 1) having a circumferential profile seal 6 on the outer circumferential side. It can also be seen in Figure 1 that the tear-off closure has a tear-open strip 7, which is provided with a tongue 8 projecting from the lid rim 2, wherein the tear-off strip is It is defined by the scribe lines 9, 9' disposed in the combined device. The scribe lines on both sides generally have the same length, but can vary from half the length 9, to the full length 9. The tab 8 is attached to a pull member 1 〇. A different embodiment of the tear-off closure device in accordance with the present invention is shown in Figures 3 through 14. -14- (12) 1301530 In contrast, Figure 2 shows a bottle closure device in this particular embodiment as a crown cap closure device, wherein the circumferential rim 2 is provided with the common float Convex ridges or teeth. A different embodiment of a crown cap closure device in accordance with the present invention is shown in Figures 15-19. According to the invention, the upper cover panel 1 has one or a plurality of at least partial circumferential projections 12, 12a, 12b, 13, 13a, 13b on its underside facing the sealing insert 5, which is embossed It is made and interacts with the contour seal 6 to form an exhaust valve and for this purpose protrudes or projects into the region of the contour seal 6. These embossings are not shown in Figures 1 and 2. The contour seal is formed in a generally L-shaped cross section and has an outer first seal ring 6a and an inner second seal ring or surface 6b, wherein the outer seal ring 6a has a comparison with the inner seal ring 6b Large height and a small width. In the embodiment according to Figures 3 to 7 and 15 to 17, the projections or embossings are made as circumferential step portions 12, 12 & or 12b and have a lowering towards the center of the cover. Side 1 4. In this way, a central portion of the lid 15 is pressed in the central region of the lid to provide an entire lower central panel 15 . For example, one of the comparisons of Figures 3 and 15 clearly shows that the same embossing according to the present invention can be provided for both the tear-off closure device and for the crown closure closure device. The principle of its function is not affected by the scribing provided by the tear-off closure. Conversely, the step portion 1 2 in accordance with the embodiment of Figures 3 or 15 extends around or fully extends through a full angle of 360 degrees.具体 Figures 4, 5 and 6 show a specific embodiment' in which a plurality of step portion sections 1 2 a, 1 2 b having different radii R, R· are provided. According to Figures 4, 5, 6 ' these steps

-15- (13) 1301530 each of the segments 12a, 12b extends over a predetermined angle of 5 or (T. Here the radius R, R of the step portion means the upper portion, that is, the step portion Radius in the upper edge region. According to Fig. 4, a two-circumferential step portion 12a is provided, each step extending around an angle δ of approximately 150 degrees, and giving a reduction effect 'these step portions have a substantially Corresponding to the radius R of the inner radius P i of the contour. The luer phase aligners of the two step portions 2 a form a step portion 1 2 b of the valve, and the frame is configured such that the step The portion 1 2 b is generally disposed in the region of the evening f ring 6 a. In this case, the step sections forming the valve are provided with different lengths, that is, they cover different angular regions. The same principle application To the specific embodiment in Fig. 16, wherein the step portion 1b of the valve is formed, the section extends over the area. According to Figures 5 and 6, the step portion 12a extends over $3 20 degrees. The angle (5, and the step portion 12b extends over: the angle of the angle (5'. Figure 5 shows a specific embodiment in which the step portion 12b is partially inside the region of the contour seal 6. The (upper) radius R' of step 12b and the step portion 12a (both upper R) Is smaller than the outer radius Pa and larger than the contour inner radius Pi. However, the inner radius Pi of the "lower" radius profile seal 6 of the step portions is smaller. The lower radius is the lower edge region of the step. Radius in the middle. The inclined flat step portion having a width of about 1 11 2b constitutes the exhaust valve 1 2b, and affects the radius of the range, the venting seal of the step portion 6 and the radius of the radius R 丨 the sealing step portion ( 5, or (T for four corners and about 40 12a, step portion) of the radius of the seal than the step degree α of the interior • 16- (14) 1301530

The seal ring 6b releases the internal pressure to open the outer seal lip portion 6a at a predetermined internal pressure in the bottle. The valve function is enhanced by the steeper step portion side 12a having an inclination a of about 20 degrees and about 50% of the inside of the inner radius of the contour seal. The step portion 1 2b of Fig. 6 corresponds to the step portion 1 2b of Fig. 5. Furthermore, there is also a step portion 12a extending over an angle 5 of 340 degrees. The steep step portion 12a has a slope α of about 60 degrees and an (upper) radius R which is exactly the same or slightly smaller than the inner radius Pi of the contour seal. The lower radius is smaller than Pi, however, the step portion is sufficiently close to affect the inner seal ring 6b. This valve function is achieved by a flat step portion side 1 2b having a tilt angle α of about 10 degrees, and the narrow exhaust valve is formed. In the specific embodiments of Figures 8 to 14 and 18 and 19, the embossing is formed into grooves 13, 13a, 13b of predetermined width B and height ,, and extends over a predetermined angular range, wherein the grooves Each of the slots has an outer side surface 16 that descends toward the center of the cover and an inner side surface 17 that rises toward the center of the cover. Here, the width B means the "upper width", that is, the total width of the groove in the upper edge region. In the specific embodiment from Figures 8, 9, 10 and 19, the grooves 13 are each formed as a complete circumferential annular groove 13 . That is, the groove 13 extends over the entire angular region or over a full angle of 3 to 60 degrees. The exhaust effect can be specifically set by the position of the groove 13 relative to the contour seal 6. Thus, in contrast to Figures 8 and 9, Figure 10 shows a particular embodiment with a reduced exhaust effect since the groove according to Figure 1 has been further displaced into the region of the inner seal ring 6b. However, the groove 13 is also made as a -17- (15) 1301530 full circumferential groove. In contrast, Figures 11 and 12 show a specific embodiment in which a plurality of groove segments 1 3 a, b ′ are provided which extend only over a limited angular region 6, δ'.

A comparative check of one of Fig. 12 and Figs. 12a and 12b clearly shows that each of the individual trenches of the four trenches 1 3 a-1 3 b is differently structured. For example, a second groove 13a having a very strong valve effect is provided, wherein the outer side 16 is disposed in the region of the outermost edge of the contour seal (or slightly outer). In this region the outer radius Ra of the groove corresponds approximately to the outer radius Pa of the contour seal 6, or even slightly larger. In this region, the inner radius Ri is smaller than the outer radius Pa of the seal member 6 and larger than the inner radius Pi of the seal member 6. The other, but weaker, relief valve effect is achieved by a two-diameter opposing groove 1 3 b of the same length, wherein the lowered outer side 16 extends approximately the total width b of the contour seal 6 . Figure 11 shows a specific embodiment with an extended angle (5 long trench section 13b and a short span section 1 3 a extending over the angle (5') and acting as an exhaust valve. 3 b is completely in the region of the contour seal, whereas the groove portion 13 3 is only partially in the region of the contour seal. The groove side 16 of the groove 13 a has a flat slope And partially outside the contour seal to increase the venting effect. Furthermore, Figure 14 shows a specific embodiment in which a plurality of groove segments 13 a, b are provided, all of which have the same shape, But configured at different radii

Ra ' Ri. Thus, the two-diameter opposing short groove 13a is disposed in a region of the lip-type outer seal ring 6a over a relatively large outer radius Ra and an inner radius Ri, and vice versa as shown in FIG. The ground length -18-(16) 1301530 groove 1 3b is disposed in the region of the flat inner seal ring 6b, and thus extends over a reduced outer radius Ra and inner radius Ri. In this case, the valve function is taken over by the two outer grooves 13a. Here, the groove sections 1 3 a, b are substantially U-shaped in cross section. A comparative analysis of various exemplary embodiments clearly shows that the geometry of the embossments 12, 12a, 12b, 13, 13a, 13b according to the present invention can be designed in many ways to suit the desired situation and is particularly suitable for Use the φ seal architecture. Thus, the inclination angle α of the step portion can be made rather steep and has an angle of 45 to 90 degrees with respect to the horizontal plane, for example, 60 to 80 degrees (see Fig. 3a). However, it is also possible to select a flat tilt angle α in the region of the step portion, which may be, for example, 10 to 45 degrees (see Fig. 4a). The inclination angles /3 and r of the side faces 16 and 17 of the circumferential groove can be similarly selected. For example, Figure 8a shows a specific embodiment of a tilt angle Θ having a relatively steep outer side 16 with a relatively flat rising inner side 17 followed by this side 16 . An inverted configuration is provided in the specific embodiment of Figure 12b. Moreover, it is clear from the drawings that the L-shaped profile seal 6 can also be designed to accommodate such conditions within the limits. Always implementing an outer sealing ring or sealing lip 6a that is directed substantially vertically downwards, under compression, which is compressed on its outer side top 3a and outer side surface 3b by its inner surface 18, As shown in Figure 20 or 21, a satisfactory seal is provided. In contrast, the inner seal ring or surface 6b is flat so that it is softly compressed on the top surface 3a without surrounding the inner surface 3c of the bottle. In this way, it has been ensured that the inner seal ring 6b can be surrendered during the pressure rise so that the release of pressure can occur -19-(17) 1301530. It can also be seen in the drawings that the sealing surface 19 below the inner seal ring 6b is arranged substantially horizontally. In this case, the substantially horizontal one also includes those embodiments in which the sealing surface 丨 9 is in one direction or in one direction relative to the horizontal plane at 1 to 20 degrees, for example, 1 5 degrees. Quite a small angle tilt. For this purpose, you should refer to the figure! 8 and 19 show a suitably inclined sealing surface 19 . However, it is particularly important that the true inner seal ring of this height is at a distance from one of the outer seal ring φ or lip, the inner seal ring surrounding the inner surface of the neck of the bottle 3 c (C-shaped profile seal) The type) prevents or strongly reduces the release of pressure and the interaction of the contour seal with the embossing. In each case, the thickness and sealing efficiency of the contour seal 6 is reduced to some extent by the embossing so that the sealing properties can be adjusted by the shape and depth and position of the embossing. In addition, a significant savings in one of the materials can be achieved, and the overall manufacturing will be inexpensive, as conventional techniques that have been established can be used with smaller tooling variations. Finally, 0 may additionally achieve hardening of the cover provided by the embossing, whereby the opening process can be advantageously influenced by the special leverage effect. At this point, 'as in Figure 7, another upwardly directed image step portion pattern 20 is provided at a distance inside the inner radius of the contour seal, which has no effect on the valve effect, but achieves one Hardening function. The same principles apply, for example, to the specific embodiments of Figures 4, 12 or 14. In these cases, the effect of forming the valve is generally achieved by the "short" embossing, and the "long" pattern along the tear line is only the second most important for the formation of the valve, but advantageous The closure device is torn by the helpful lever arrangement.

-20 - (18) 1301530 In these drawings, the bending radius of the step between the cover panel and the descending side 14 of the step portion and the descending side of the step portion and the bottom plate is also indicated. And a radius of curvature between the cover panel and the descending side 16 , between the falling side 16 and the rising side 17 and the groove between the rising side 17 and the cover panel . At a smaller radius r, a significant embossing bend is achieved, and at a larger radius r, a more rounded embossing bend is achieved.
