Definitions

  • the invention relates to a bottle stopper, in particular for champagne bottles, in which the closure body, which is formed in one piece from plastic, has a sealing shaft which enters into the bottle neck in the form of a stopper, which extends centrally from the bottom inner surface of a cap, the jacket wall of which is provided on its inner surface with projections which are in engagement to the external thread of the bottle neck.
  • a bottle stopper of this type is known from DE-OS 28 33 099.
  • the closure body which is formed in one piece from elastic plastic, carries lamellar projections on the inner surface of its jacket wall and oriented in the direction of assignment. The latter deform when the closure body is placed on the bottle neck. The catchy thread of the same is pressed into the strip-shaped projections from the narrow side thereof. This will unscrew the bottle cap.
  • the safety in use of such a bottle cap is particularly critical in the case of bottles filled with C02-containing liquids. A certain creep behavior of the plastic material used can lead to a gradual migration of the sealing shaft, despite the bulbous design of the sealing shaft sitting in the bottle neck. The largest cross-sectional diameter is in the area of the thread.
  • the object of the invention is to remedy this situation and to provide a generic bottle stopper which, while maintaining the advantageous one-piece structure and despite normal thread, provides an optimal, locking agent-free seal and in which the desired "plop" effect always occurs reliably.
  • the special design of the sealing shaft means that normal, ie, fully formed, threads can be used.
  • the connection between the closure body and the bottle neck is no longer based on a resetting clamping force between the two parts produced by material displacement, where one is also bound to a special choice of material (deformable and yet firm). Unscrewing the closure is easier because of the restoring force of the material due to increased friction on the thread.
  • the stopper-like closure body jumps off to produce the desired "plop" effect, since the sealing shaft has at least one transverse annular sealing rib projecting over the circumferential surface in an area which is in front of the thread area.
  • the multi-start thread has the advantage that the exit from the counter-thread of the bottle neck takes place without any tendency to tip, as can be assumed with a single-start thread.
  • the structural measure that was also taken that the inner wall of the hollow cover shaft is provided with a plurality of longitudinal corrugations results in a durable assignment of a filling core stiffening the sealing shaft from the inside and supporting the annular wall, for example in the form of a cork.
  • the inner surface of the jacket wall extends in three successive step sections, the middle of which carries the threads that extend as far as the base section on the floor serving as a support surface for the bottle neck.
  • the individual step sections are used in accordance with the stabilization requirements, in particular with regard to the selected spherical outer shape of the closure body: This results in a reduction in area for the step section forming the supporting surface, which leads to a kind of triangular lip.
  • the step section with a wider cross-section is used to create the deepest possible thread.
  • the last step section on the edge of the cap forms a thin-walled apron surrounding the bottle bead.
  • the inner wall of the bottle neck is cylindrical in shape at least over the immersion area of the sealing ring lying in front.
  • the bottle stopper 1 is designed as a spherical cap. It is realized as a one-piece closure body made of plastic.
  • a free-standing, cylindrical sealing shaft 3 extends centrally from the bottom inner surface 2 for plug-like entry into the opening 4 of the neck 5 of a bottle 6.
  • the sealing shaft 3 has a plurality of annular, equally high sealing ribs 7 protruding beyond its jacket or circumferential surface 3 '.
  • the inner wall 11' of the bottle neck 5 is of cylindrical design at least over the immersion area of the sealing ring 7 lying in front.
  • the latter run in the transverse plane EE and are arranged at a distance from one another which corresponds to at least one and a half times the width of a sealing rib 7.
  • Their cross section is semicircular in Fig. 1 and triangular in Fig. 2. It is an equal sided triangular shape, one side of the triangle rooted in the cylindrical peripheral surface 3 'of the sealing shaft 3.
  • the distribution of the individual sealing ribs 7 on the sealing shaft 3 is such that a plurality of sealing ribs 7 extend in the area of a thread 8 of the cap.
  • the latter is designed as an inward projection V on the inner surface 9 'of a jacket wall 9 concentrically surrounding the sealing shaft 3 and is in engagement with the corresponding external thread 10 on the neck 5 of a bottle, in particular a champagne bottle 6 (see FIG. 2).
  • the sealing shaft 3 protrudes beyond the projection V formed as a multi-start thread 8; at least one of the sealing ribs 7 is located at the level of the last, the bottle neck 5 facing thread 8 'or beyond it, that is on the projecting section A of the sealing shaft 3. This has the consequence that until the thread 8 emerges from the external thread 10 of the Bottleneck 5 tight closure is present.
  • the increased internal pressure due to the release of carbonic acid now presses the closure body. abruptly producing the desired "piopp" effect from the closed position. Since practically only one sealing rib 7 is in sealing engagement with the bottle neck at the time the thread emerges, the sealing ribs 7 arranged above it no longer occur, or not all, as a friction factor. The bottle mouth is suddenly released.
  • the multi-thread 8 and correspondingly designed external thread 10 ensure the necessary tilt-free displacement of the sealing shaft 3.
  • a two-start thread is sufficient, the thread extensions 8 "then being diametrically opposite one another.
  • a three-start helix thread is more favorable due to the three-point tap or thread outlet of the two threads to be obtained therefrom (FIG. 3).
  • the inner surface 9 'of the jacket wall 9 runs in three successive step sections.
  • the middle step section carries the multi-start thread 8.
  • the thread 8 extends to a support surface 13 formed by the next step section for the end ring surface 14 of the bottle neck 5.
  • the ring-shaped support surface 13 provides an additional seal of the cap on the bottle neck 5.
  • the support surface 13 is partially in one Ring groove 15 over. The latter concentrically surrounds the base of the sealing shaft 3. Due to the reduction in the area of the support surface 13, the sealing effect is increased. So there is a more lip-like projection.
  • the inner wall 16 of the hollow cylindrical sealing shaft 3 which is open towards the bottle neck 5 is provided with a plurality of longitudinal corrugations 16 1 .
  • the corresponding cavity serves as shown in FIG. 2 for receiving a cork 17, should such be desired in the case of high-quality bottle contents.
  • the corrugation contributes to its definition, which is further increased by the pressure on the inside of the bottle neck.
  • the inner wall 11 'of the bottle neck 5 is shown in broken lines.
  • the sealing shaft is reproduced in its physical shape in order to be able to reproduce the basic shape of the sealing ribs 7.
  • Fitting the bottle with the bottle stopper according to the invention is made easier by the measure that the outer edge of the sealing shaft 3 on the side of the assignment is chamfered at 18.
  • a corresponding chamfer 19 is located on the inner edge of the end ring. surface 14 of the bottle neck 5.
  • the grip of the bottle stopper is increased by vertically oriented corrugations 20 provided on the outside of the cap.
  • the corrugations 20 are interrupted at the level of the thread area, in that an annular rib 21 extends around the entire circumference of the ball, essentially in the area of the horizontal center plane of the ball. It represents an advantageous, stabilizing strapping due to the material accumulation going beyond the already increased wall thickness there.
  • the jacket wall 9 merges into a zone with a reduced cross section. This forms an apron 23 that completely or partially overlaps the collar 22 of the bottle neck.
  • the operator When the bottle is reclosed with the bottle stopper 1, the operator will first have to overcome a slight resistance, namely the resistance that is required to spend the lower sealing rib 7, which maintains the seal until the end, in the bottle neck. Only then does the three-start thread of the cap engage in the external thread of the bottle neck 5 when screwing.
