Definitions

  • the invention relates to a closure for a container, especially a bottle, comprising an upper covering panel and a circumferential collar or skirt adjoining the covering panel on the outside, wherein a sealing insert or liner is arranged on the underside of the covering panel which has a circumferential profile seal along the outside periphery.
  • a closure is also known as (closure) lid or (closure) cap.
  • the closure within the scope of the invention is a "non re-usable" closure, especially a bottle closure which can be constructed for example as a crown cork closure or a tear-off closure. In both cases, the upper covering panel of the closure incorporating the profile seal is pressed against the bottle top at the sealing of the closure on the bottle.
  • the circumferential band or collar which forms a cylindrical closure skirt embraces the bottle neck bead after sealing and the lower part of the skirt provides a firm grip under the bead ring.
  • the skirt is provided with the usual crown cork stamping or teeth with the corrugations pressed against and slightly in under the bead ring, giving the appropriate grip.
  • the skirt is crimped in under the bead ring and a tear-off strip is provided, which is defined by score lines in the covering panel and the skirt wherein this tear-off strip continues as a tongue protruding beyond the skirt and a pulling member, e.g. a pull-ring, is connected to this tongue.
  • Bottle closures are known in a wide range of embodiments both as crown-cork closures and as tear-off closures.
  • a constant problem is the handling of carbonated liquids in bottles.
  • the bottles In order to ensure a high and constant quality of carbonated beverage for example, the bottles must be securely closed with the provided closures eliminating leakage of carbonisation.
  • considerable internal pressures can occur in bottles filled with carbonated liquids.
  • Such high internal pressures can especially occur when the filled and closed bottles are exposed to high temperatures and/or violent movements, e.g. during transport.
  • Considerable problems can arise therefrom since at such high pressures there is the risk that the bottles, whether these are made of glass or plastic, will explode or burst.
  • a considerable risk of injury is associated therewith for the user or neighbouring third parties.
  • crown cork closure for example, the crown cork is caused fiercely leaving the bottle top by such a high inner pressure.
  • the manufacturers of bottle closures and for the beverage manufacturers or bottlers such risks are already barely acceptable because of the risk of any liability associated therewith.
  • the filled and closed bottles must easily be able to withstand pressures of 6 bar without any significant pressure loss since beverages are exposed to such pressures for example during pasteurisation processes.
  • crown corks and other closures are constructed to stay firmly on the bottle top at inner pressures below 10 bar.
  • the object of the invention is to provide a closure for a container, especially a bottle closure, which can not only be used universally on conventional bottle neck beads and is simple and cheap to manufacture and seal but in addition, on reaching a predicted inner pressure makes it possible to achieve a specific release of pressure and subsequent problem-free reclosure.
  • the invention defines and instructs that the upper covering panel has on its underside (facing the sealing insert) at least one projection, e.g. embossing, extending at least over a predefined angular region, which projects in the area of or close to the profile seal and interacts therewith forming a venting valve.
  • the upper covering panel has on its underside an annular sealing liner located peripherally with an outer protrusion adjoined inside with a lower and wider ring, in combination, constituting a liner configuration ("profile seal") being designed to interact with a defined embossing, stamping or shaping of the upper covering panel, thereby forming a venting valve.
  • the invention starts from the knowledge verified by experiments that the function of the seal can be specifically influenced if the covering panel is provided with an underside projection, e.g. embossing, stamping, moulding in connection with the area of the profile seal and constructed to interact with the profile seal.
  • an underside projection e.g. embossing, stamping, moulding in connection with the area of the profile seal and constructed to interact with the profile seal.
  • the solution according to the invention functions in the same way in tear-off closures as in crown cork closures.
  • the performance of the closure is not influenced, for example, by score lines provided with tear-off closures.
  • the conventional standard bottle necks of crown cork type can be used. This is valid for all known bottle neck standards including the European, the American (GPI), the Japanese and similar, all having slightly different neck profile or configuration.
  • the bottles can be made of glass or plastic.
  • Profile seal means a seal with a "step-like" cross section.
  • the profile seal is constructed as substantially L-shaped in cross-section with an outer first (lip-type) sealing ring and an inner second (flat) sealing ring or sealing surface, wherein the outer sealing ring has a greater height and/or a smaller width than the inner sealing ring.
  • the invention starts from the knowledge that such a profile seal in interaction with the projection or embossing according to the invention makes it possible to achieve a particularly specific and above all reproducible release of pressure.
  • the projection or embossing is constructed as a circumferential step with a side descending steeply downwards, forming for example a lower central plate of the covering panel.
  • This step can, for example, be constructed as a completely circumferential step with completely identical radius, forming a circular cap central region when viewed from above. It is to be understood that the step itself is located radially to interact with the profile seal, forming a valve. The desired venting effect can be adjusted by tuning the various parameters.
  • the circumferential step can have a plurality of step sections with different radii which each extend over a predetermined angular region.
  • the step is arranged over a predetermined circumferential region in such a radius which fulfils a stronger venting valve function together with the profile seal whilst the other regions of the step are arranged on a different radius which merely possess a small valve-forming function.
  • the desired pressure release or venting effect can be further specified by selecting the corresponding circumferential regions.
  • the radius of the step or at least of a step section can be smaller than or equal to or slightly greater than the outer radius of the profile seal and/or greater than or equal to or slightly smaller than the inner radius of the profile seal, thus including that the radius of the step can be of any size greater than the inner radius of the inner sealing ring up to the outer radius of the outer sealing ring.
  • the venting valve constituted by the interaction between the profile seal and the embossing possibly can be given a form extending to a radius greater than the outer radius of the profile seal or smaller than the inner radius of the profile seal.
  • the step or step section is close enough to the profile seal to interact with the sealing ring or the sealing rings and thereby to influence the sealing properties of the profile seal.
  • the side angle of the step or of a step section with respect to the horizontal or with respect to the upper covering panel is for example 40° to 90°, e.g. 60° to 80°.
  • angle offers a sensitive parameter for setting the desired venting function.
  • a steep angle of approximately 90°, e.g. 80° the seal can be especially strongly influenced and thus a stronger venting valve effect can be achieved.
  • flat angles 10° to 40°.
  • the projection or embossing is constructed not as a (single) step but as a groove or channel of predetermined width and height, which runs around or extends over a predetermined angular region, with an outer side descending towards the centre of the cap and an inner side ascending towards the centre of the cap.
  • the ascending inner side can directly adjoin the descending outer side.
  • the groove can be constructed as a circular-ring-shaped, completely circumferential groove viewed from above, which extends over the total area of the cap and thus over a full angle of 360°.
  • the invention also comprises embodiments in which the projection is constructed as a protrusion connected to or moulded onto the underside of the upper covering panel.
  • the embodiment with embossed groove(s) or step(s) are all distinguished by their particularly simple manufacture.
  • the angle of inclination of the descending side with respect to the horizontal and/or the angle of inclination of the ascending side with respect to the horizontal can be 40° to 90°, e.g. 60° to 80°.
  • the angle(s) of inclination can also be 5° to 40°, e.g. 10° to 40°.
  • the groove or the protrusion can be constructed symmetrically or asymmetrically, i.e., with identical or unequal angles of inclination.
  • the outer side is constructed as a steep side and the inner side is constructed as a flat side or vice versa.
  • the desired degassing effects can be sensitively influenced.
  • the invention proposes that the outer radius and/or inner radius of the groove or at least one groove section is smaller than or equal to the outer radius of the profile seal and/or greater than or equal to the inner radius of the profile seal.
  • the grooves or groove sections are thus arranged at least partly in the area of the profile seal. They can be arranged completely in the area of the outer sealing ring or also completely in the area of the inner sealing ring.
  • the groove or a groove section can also extend from the area of the outer sealing ring into the area of the inner sealing ring. Moreover it is possible that the inner radius and/or the outer radius of the groove is slightly smaller than the inner radius of the profile seal or that the outer radius and/or the inner radius of the groove is slightly greater than the outer radius of the profile seal. However the groove or at least one groove section must be close enough to the profile seal to interact with the profile seal and thereby to influence the sealing properties of the profile seal.
  • the width of the groove is preferably 1 mm to 4 mm, e.g. 1 mm to 3 mm.
  • the height of the groove or step can be 0.1 mm to 0.8 mm, e.g. 0.2 mm to 0.6 mm.
