Definitions

  • the invention relates to a closure of the type mentioned in the preamble of claim 1 for a bottle and the like, and to a method for producing the same.
  • Sealing-flat axial sealing surfaces are provided in the region of the mouth edge of a bottle, into which the sealing compound of the seal extends.
  • the sealing part is deep-drawn and extends around the mouth of the bottle to form the outer, axial sealing surface.
  • the Wesshtl one of this known closure should consist in the fact that the sealing part at least m a portion of the transition. the sealing part to the holding part not up to the. lateral mouth edge of the neck of the bottle is deep-drawn, rather exempt from such deformation. In this way, a prevented sealing section is to be created in the undeformed partial area, which should lead to a lower tightness due to its shortness. In this way, the escape of excess pressure is to be promoted. With such a closure, the escape of excess pressure is less dependent on the sealing section than on the contact pressure of the seal. However, this is part of this known closure over the entire mouth edge the same. The desired effect of a pressure relief valve is therefore only very incompletely achieved.
  • a closure for a bottle or the like which has a cap-shaped holding part on which there is an inward projection or collar for engaging behind an outer bead of a bottle neck.
  • This holding part is connected via an elastic element to a sealing part with an annular sealing surface for contact with an end face of the bottle neck.
  • the holding part has a stop for the defined contact of the holding part on the edge of the bottle neck. Since the sealing part also abuts the edge of the bottle neck, the mutual position of the holding part and the sealing part is precisely defined. Since the elastic element for prestressing the two between them
  • the size of the preload of the elastic element is thus precisely defined and thus the pressure at which the sealing part lifts off, ie the pressure relief valve opens.
  • DE-OS 1 432 224 discloses a ventilation seal for a closure similar to the previously discussed US Pat. No. 4,089,434, the difference being that the areas of reduced thickness of the seal are located only at two diametrically opposed short circumferential points. Most of the seal is thicker. The disadvantages described above are therefore even greater.
  • the inside of the bottle for example a beverage liquid
  • the invention has for its object to provide a closure of the type in question, which is simple in structure and opens largely reliably regardless of the screwing torque at a given excess pressure.
  • the invention is also based on the object of specifying a method for the simple manufacture of a closure of the type mentioned in claim 1.
  • the invention frees itself from the known idea of shortening the sealing distance or the sealing part as a whole via an elastic element against the mouth of the
  • Bottleneck to press Rather, the basic idea of the invention is to create a seal, stop and elastic element only by designing the annular sealing surface or the seal.
  • the sealing pressure is also on the recessed areas of the annular surface exactly Determinable and thus the pressure at which the seal lifts off the end face of the bottle neck and thus allows excess pressure to escape.
  • the seal is compressed less in the closure case and is thus pre-tensioned so that it lifts off at the desired overpressures and allows overpressure to escape.
  • the seal can be shaped over the circumference to complement the annular sealing surface of the sealing part, so it adapts to the contour of the sealing surface. In the simplest case, this means that when the closure according to the invention is in the form of a cap, there is simply a depression in the annular sealing surface which also fills the material of the seal, while the bearing surface of the seal on the end face of the
  • Bottle neck lies in a radial plane.
  • Such a closure can be produced in a simple manner according to the teaching of method claim 8, the recesses being able to be produced during the closing process without additional effort, while only the corresponding material, e.g. Foam material must be selected, which then also represents no additional effort.
  • Seal can also be a profile seal, in particular a lip seal, the profile being shaped to be complementary to the annular sealing surface over the circumference.
  • the seal has a constant thickness and consists of material of different compressibility over the circumference.
  • the material of the seal can have cavities, in particular bubbles, at some points, as a result of which foam is practically formed at these points.
  • the material of the holding and sealing part s can be arbitrary, for. B. plastic or metal. It can be a screw or crown closure or any other closure.
  • Fig. 1 shows an embodiment of the invention
  • FIG. 2 is a top plan view of FIG. 1 and FIG. 3 is a side view of FIG. 1.
  • FIG. 4 illustrates the method according to the invention
  • FIG. 5 shows an intermediate step in the method according to the invention
  • Fig. 7 shows another embodiment of the
  • Fig. 8 shows a top view of the seal
  • a holding part 1 and a sealing part 2 together form a screw cap, for which purpose screw threads 3 are provided in the holding part 1, with which the holding part 1 can be screwed onto bead-shaped threads 4 of a bottle neck 5 of a bottle 6, which is only partially shown.
  • Holding part 1 and sealing part 2 are deep-drawn and / or pressed from aluminum, as is generally the case with screw closures of this type.
  • the sealing part 2 In its edge area, the sealing part 2 has an annular sealing surface 7, which springs back at three points 8 and is thus at a greater distance from an end face of the bottle neck 5 than the annular sealing surface 7.
  • seal 10 Between the annular sealing surface 7 or its recessed locations 8 and the end face 9 of the bottle neck 5 there is a seal 10, the sealing surface 11 of which lies in a radial plane with respect to the bottle neck 5, while the one lying on the other side Sealing surface 12 is complementary to the annular sealing surface 7 or the recessed locations 8.
  • the seal 10 consists of volume-compressible material, for example of foam.
  • Fig. 1 shows the screw cap
  • Screw-on closure During unscrewing in the area of the thinner peripheral parts of the seal 10 in the area of the annular sealing surface 7 there are very quickly larger bearing forces which act in a sealing manner and at the same time prevent further screwing on of the screw cap, so that it is in a precisely defined position
  • a likewise flat sealing washer 18 is inserted into a cap-shaped closure, consisting of holding part 16 and sealing part 17, which is flat. Everything is then placed in the direction of an arrow 19 on the end of a bottle neck 20, as shown in FIG. 6. Then a stamp 21 is pressed in the direction of an arrow 22 against the sealing part 17.
  • a recess 23 from which a projection 24 protrudes, which presses in the sealing part 17 when the stamp 21 m is pressed and there Vertie at distant locations generated, as can be seen from Fig. 6.
  • a thread (27) as well as a collar (28) are produced by means not shown, by pressing from the outside onto the holding part (16), which serves to make the first opening of the bottle visible.
  • FIG. 7 shows, similar to FIG. 1, a section through an upper part of a bottle neck, identical or corresponding parts are provided with the same reference numbers.
  • a sealing part 26 is completely flat, while at the same time a seal 27 has the same cross section.
  • this seal has three areas 28, 29 and 30 which have a lower, preferably substantially less compressibility than a central area 31. These areas 28, 29 and 30 thus act as stops and determine the compression of the central region 31 of the seal 27 in the region of the sealing surface. At these points, the material of the seal can therefore lift off the sealing support at a certain excess pressure and thus allow excess pressure to escape.

Abstract

L'invention concerne un bouchon pour bouteilles ou similaire et son procédé de production. Le bouchon comprend une partie de retenue (1) sur le goulot de la bouteille, une partie d'étanchéité (2) retenue par la partie de retenue et qui a une surface d'étanchéié (7) essentiellement annulaire, entre laquelle et la face frontale annulaire du goulot de la bouteille est agencée une garniture d'étanchéité (10) en un matériau compressible. La garniture d'étanchéité s'appuie sur la surface annulaire d'étanchéité avec des pressions différentes à différents endroits. Les endroits sur lesquels s'exercent les pressions les plus fortes servent de butée et définissent la position de la partie d'étanchéité, ainsi que l'importance de la compression des endroits (8) sur lesquels s'exercent les pressions moins fortes, qui forment une soupape de sûreté. La garniture d'étanchéité, la butée et l'élément élastique sont ainsi aisément obtenus par la seule configuration de la surface annulaire d'étanchéité ou de la garniture d'étanchéité elle-même.
