Definitions
- the invention relates to a bottle stopper consisting of a plastically deformable metal cap which covers the bottle and which has a flanged edge area which positively engages around the bottle in the closed state, and a sealing element which rests against the bottle in the opening area and closes the bottle, wherein the sealing element consists of a disc closing the opening of the bottle, which is adjoined by a substantially hollow cylindrical section, which is inserted in the closed state into the opening of the bottle and abuts the inner wall of the bottle, and wherein an edge region of the disc over the hollow cylindrical Section protrudes to rest on the bottle.
- Bottle closures of the type described above are generally also referred to as crown caps. These are used in particular to close bottles that contain carbonated beverages, such as beer or lemonades. Crown caps have a very simple structure and are inexpensive to manufacture. With appropriate design of these crown corks, sufficient sealing action is also achieved in order to be able to guarantee a secure closure of the bottle and to ensure that sensitive beverages, such as beer, have an adequate shelf life. The shelf life of beer depends largely on the rate at which gases can diffuse through the cap.
- bottle closures are so-called clip closures, in which a closure element provided with a seal is fastened to the bottle via a lever construction, which is generally made of wire, and ensures a tight fit of the sealing element in the closed state.
- clip closures In addition to an improved sealing effect compared to a crown cork, such clip closures have the advantage of producing a strong and rich "PIopp" sound when opened.
- Such clip closures are complex to manufacture and correspondingly cost-intensive, and bottles equipped with such closures are difficult to integrate into a deposit cycle.
- the object of the present invention is to develop a bottle cap of the type described above in such a way that a powerful and rich sound can be achieved when the bottle is opened without additional effort.
- a two-part bottle cap for champagne bottles is known from AT 401.378 B.
- the bottle cap consists on the one hand of a crown cap of a conventional type, that is to say of a sheet metal cap with a sealing plate arranged in the interior of the sheet cap and a plastic stopper made of a hollow cylindrical tube piece.
- the bottle stopper is constructed so that after the crown cap is removed, the plastic stopper initially remains in the opening of the bottle and can then be broken along a pre-formed groove to open the bottle.
- both the plastic stopper and the crown cork are self-contained closure systems, which is expressed, among other things, by the fact that the sealing plate of the crown cork must protrude radially over the plastic stopper in order to lie directly on the bottle and thus an independent sealing surface to be able to realize.
- the sealing effect of the plastic plug takes place primarily or exclusively along the outer surface of the hollow cylindrical pipe section, which requires a corresponding pressure.
- a further problem with the solution described in AT 401.378 B is that such a bottle closure can only be sensibly arranged in the mouth area in the case of bottles with a relatively low-tolerance inner diameter. If larger tolerances occur, the plastic stopper on some of the bottles will not have sufficient contact pressure to ensure tightness. With another part of the bottles with a relatively small inner diameter, however, it will not be possible without difficulty in the normal production process to drive the bottle cap into the bottle. In the case of high-quality drinks, such as sparkling wine, it is possible to comply with relatively small tolerances in bottle production, since the production costs of the bottle only play a relatively minor role compared to the price of the product. In the case of mass-produced products such as beer or carbonated lemonades, the production costs of the bottles are critical and the corresponding tolerances cannot be specified arbitrarily.
- Another object of the invention is therefore to provide a bottle stopper which can also be used in the normal production process with conventional bottles without problems.
- the sealing element is firmly connected to the metal cap and that the edge region of the sealing element has a sealing groove which is intended for sealing against the bottle in the region of its end face.
- the solution according to the invention makes it possible to present a bottle cap of very simple construction, which gives a very powerful and rich "plop” sound when the bottle is opened, even if it is ice-cooled.
- the hollow cylindrical section is prestressed in the closed state with respect to the inner surface of the bottle. This prestressing is achieved, inter alia, in that the outer diameter of the hollow cylindrical section in the force-free state is larger than the inner diameter of the bottle in the opening area.
- the sealing element consists of a composite material made of ethyl methyl acrylate and a thermoplastic vulcanizate of a thermoplastic elastomer.
- the material of the sealing element must be sufficiently soft to achieve a sealing effect even with relatively low contact pressures on the other hand, be sufficiently rigid to be able to be pressed into the bottle opening without problems even at high production speeds.
- the above material optimally fulfills these requirements and is also within the permissible range in terms of cost.
- the sealing element is molded onto the metal cap in an injection molding process. This enables a simple and inexpensive manufacture of the bottle stopper according to the invention. As an alternative to this, it would also be possible to glue the sealing element into the metal cap, but this requires more complex production.
- the hollow cylindrical section of the sealing element has a length which is less than the axial extent of the metal cap.
- the bottle caps are usually transported in bulk from the production plant to the filling plant. The shocks that occur during transport can cause metal caps to damage sealing elements of other closures. This risk is minimized by the fact that the sealing elements do not protrude beyond the plane spanned by the edge of the metal cap.
- a particularly good sealing effect is achieved in that the sealing groove of the sealing element has an essentially trapezoidal cross section.
- a further particularly preferred embodiment variant of the invention provides that the hollow cylindrical section of the sealing element consists of a base section, a middle section with essentially cylindrical inner and outer surface and an insertion section with a chamfer or rounding at the end, and that the base section is opposite the Middle section is thickened and has a height that is greater than the wall thickness of the middle section.
- the hollow cylindrical section in the area of the transition to the disc is particularly rigid, so that there is particularly good support with respect to the bottle opening in this area.
- the hollow cylindrical section in the area of the base section has on its inside a toroidal transition surface whose radius of curvature in the longitudinal section is greater than the wall thickness in the area of the central section.
- the metal cap it is possible for the metal cap to generate an outward-acting bending moment in the area of the hollow cylindrical section by pressing the sealing element in the axial direction in the area of the plate, which brings about a further improvement in the opening noise.
- the radius of the toroidal transition surface is at least twice as large as the wall thickness in the area of the central section.
- a further advantageous embodiment of the invention provides that the base section is frustoconical on the outside and in the axial direction makes up more than half of the hollow cylindrical section.
- the base section can have a direct transition into the trapezoidal groove. It is particularly favorable in this embodiment variant when the outer diameter at the end of the base section is significantly larger than the inner diameter of the bottle in the region of the opening in the force-free state. As a result, when the bottle cap is driven in during production, a particularly strong deformation is brought about in the base section of the hollow cylindrical section.
- the sealing element is at least partially constructed from a material that swells under the influence of moisture.
- So-called superabsorbers are usually used to absorb unwanted moisture and keep objects dry. This is the case, for example, in baby diapers or food packaging.
- Superabsorbents based on acrylic acid are commercially available under the names Norsocryl®, Aquakeep® and Favor®.
- derivatives from phosphorylated, carbamidated starches can also be used, such as a product available under the name Carbion® S.
- the swelling creates an additional tension in the hollow cylindrical section, which increases the opening noise without the insertion of the sealing element being hindered when the bottle is closed.
- FIG. 1 shows a first embodiment variant of a sealing element according to the invention in section
- FIG. 2 shows a bottle cap with the sealing element from FIG. 1 placed on a bottle
- FIG. 3 and FIG. 4 further variants of sealing elements in a section corresponding to FIGS. 1 and Fig. 5 shows a further embodiment variant of a bottle cap in section.
- the sealing element 1 of FIG. 1 consists of a disc 2, on which a hollow cylindrical section 3 is molded.
- the disk 2 has an edge region 4 which projects beyond the hollow cylindrical section 3 and which has a circumferential sealing groove 5 which is designed to lie against the end face of a bottle opening and to form a tight seal.
- the hollow cylindrical section 3 has a rounded region 6 on an underside, which is to ensure problem-free insertion of the sealing element 1 into the bottle opening.
- the hollow cylindrical section 3 merges into the disk 2 with a toroidal transition surface 7.
- the outer circumferential surface 8 and the inner surface 9 of the hollow cylindrical section 3 are parallel in a central region, that is to say concentric.
- This area of the hollow cylindrical section 3 with the height h as an axial extension is called the middle section 11 and connects at the top to an insertion section 10 which has the rounding 6.
- the central section 11 is adjoined by a base section 12, which is delimited on the inside by the toroidal transition surface 7 and to which the sealing groove 5 is connected on the outside.
- FIG. 2 shows a bottle cap using the sealing element 1 from FIG. 1.
- the bottle cap consists of a metal cap 12 into which the sealing element 1 is molded.
- the bottle which is only partially shown, is designated by 13.
- the metal cap 12 of the bottle cap encompasses a ring bead 14 in the area of the bottle opening with a flanged edge area 15 in the usual way, whereby a positive connection is established.
- the sealing groove 5 adapts to the outer surface 16 of the bottle 13 and results in a reliable seal in this area.
- the hollow cylindrical section 3 bears against the inner surface 17 of the bottle 13 in order to provide an additional seal.
- 3 shows an embodiment variant of the invention in which the radius Ri of the toroidal transition surface 7 is significantly smaller than in the embodiment variant described above.
- the insertion section has a bevel 18 which extends at an angle of approximately 45 ° to the axis of the hollow cylindrical section 3. 3 shows relatively good results if the tolerance of the inner diameter Di of the bottle 13 is relatively small.
- FIG. 4 shows an embodiment variant which essentially corresponds to FIG. 1 and FIG. 2, with the difference that the length L of the hollow cylindrical section 3 is increased compared to this embodiment variant.
- an improved seal can be achieved in the region of the outer surface 8, and an improved opening noise can be achieved.
- Bottle closures with such a sealing element 1 are, however, more susceptible to damage, since the insertion section 10 of the sealing element 1, in contrast to the embodiment of FIGS. 1 and 2, projects beyond the flanged edge 15 of the metal cap 12.
- the embodiment variant of FIG. 5 differs from the embodiment variants described above in that a transition surface 19 is provided which forms a direct transition from the essentially trapezoidal sealing groove 5 to the outer surface 8 of the hollow cylindrical section 3.
- a region 20 is shown with broken lines, which is displaced by the application of the sealing element 1 to the bottle 13, as a result of which a relatively strong state of tension is created in the sealing element 1. This stressed state generates a torque which prestresses the insertion section 10 of the hollow cylindrical section 3 to the outside in the direction of the arrow 21. It has been found that an embodiment variant of this type is particularly insensitive to tolerances of the inside diameter Di of the bottle 13.
- the present invention makes it possible to ensure a pleasant and powerful sound when opening a bottle, the opening noise being clearly perceptible even in the cooled state.
