Definitions

  • the invention relates to a closure according to the preamble of claim 1 for a bottle or the like.
  • a closure is known from CH-A-220 476.
  • closures for bottles are either screw closures or crown closures. Both types of closure essentially consist of a cap-shaped part which is positively connected to the bottle neck. There is also a seal between the closure and the bottle neck. Because of the positive connection, the bottle is closed pressure-tight. As a result, there is a risk that the bottle will be damaged in the event of overpressure. Both with plastic bottles and with glass bottles, this can lead to breakage and leakage of the liquid, which means a considerable risk if the contents of the bottle are dangerous. In the case of glass bottles, there is also a risk of injury to people, especially the eyes, from broken glass fragments.
  • Cap-shaped closures made of plastic for bottles are also known, which are snapped onto the bottle neck. Just as they snap open, they can snap down and let excess pressure escape, however, the point at which they give in to excess pressure is not defined and, moreover, they do not close automatically after the excess pressure has released.
  • a closure of the type in question is known, which is designed as a screw closure in which the cap-shaped holding part has an internal thread with which it can be screwed onto the external thread of a bottle neck.
  • an unyielding plate which is supported against the bottom of the cap by a leaf spring.
  • a rubber plate On the side of the plate facing away from the leaf spring, there is a rubber plate as a seal which, when screwed on, rests on the upper edge of a neck of a bottle with a force which is determined by the force of the spring and by the degree of screwing of the screw cap onto the bottle neck is.
  • the invention has for its object to provide a closure of the type in question for bottles or the like, in which the escape of dangerous excess pressure is reliably ensured even with larger manufacturing tolerances above a predetermined pressure and the risk of the bottles bursting is avoided in all cases.
  • the invention is based on the basic idea of designing the closure in the form of a pressure relief valve which is dimensioned and designed in such a way that no impermissibly high pressures can arise even with larger manufacturing tolerances, such as those which occur in mass production.
  • the escape of gas or liquid from the bottle above a predetermined pressure limits the pressure to the maximum permissible level.
  • the bottle can therefore not burst, which can lead to accidents, for example damage to eyes due to flying glass fragments, particularly in the case of glass bottles.
  • the danger is also great with plastic bottles if there is a dangerous liquid in the bottle. Since bottles filled with liquid, for example bottles of carbonated lemonade, are generally stored and transported upright, excess pressure only escapes in the form of the gas, so that the liquid does not escape at all. The advantage of avoiding excess pressure is therefore only offset by the completely negligible disadvantage of the partial escape of carbon dioxide.
  • the holding part for the defined contact of the holding part on the edge of the bottle neck. Since the sealing part also lies against the edge of the bottle neck, generally further inside, the mutual position of the holding part and the sealing part is precisely defined. Since the elastic element for pretensioning the sealing element is located between the two, the size of the pretension of the elastic element is also precisely defined and thus the pressure at which the sealing element lifts off, that is to say opens the pressure relief valve.
  • the elastic element can be formed by a flexible rod, which engages with its ends on the holding part and lies in the middle region between the ends on the side of the sealing part facing away from the sealing side.
  • This rod can be made of metal, in particular steel, so that it retains its elastic properties over a long period of time and thus the opening pressure of the pressure relief valve is precisely defined over a long period.
  • the elastic element can be formed by the sealing part itself, in that it is designed to be elastic, for example by thin dimensioning or by appropriate choice of material.
  • the elastic compliance can also only partially exist, for example in the edge area.
  • Holding part and sealing part can be firmly connected to one another via the elastic element.
  • This connection can also be releasable, e.g. have the shape of a snap connection.
  • the sealing part can also have the shape of a rigid disk.
  • the elastic element can also be flat, for example in the form of a foam disc or in the form of several, distributed spring lips or the like.
  • All parts of the closure can be made of plastic or metal, depending on the requirements and the possible reusability.
  • the connection of the holding part to the bottle neck can also be arbitrary. It can be a frictional connection, but expediently a positive connection of any shape, as occurs, for example, in so-called crown caps or screw closures.
  • FIGS. 1 and 2 in two vertical sections perpendicular to each other, an upper part of a bottle neck 1 is shown on which a cap-shaped holding part 2 is arranged, which has a radially inwardly directed collar 3 and an upper bead 4 on the bottle neck 1 reaches behind and thus holds the holding part.
  • the holding part 2 lies with one Stop 5 on an upper edge 6 of the bottle neck 1, so that its position is precisely defined.
  • a round rod 8 extends diametrically, which consists of the piece with the holding part 2, so that it is pressed together from plastic.
  • this is positively releasably gripped by two lips 9, which are located on a sealing part 10, which essentially forms a rigid disc, which has a conical, annular sealing surface 11 on its edges, which on the inner part of the Edge 6 of the bottle neck 1 fits tightly. If necessary, this conical sealing surface can also be coated with a soft sealing material.
  • the position of the fitting 5, the sealing part 10 and the rod 8 are such that the rod 8 is in the closed position shown under a bias which, in connection with the surface of the sealing part 10, determines the pressure at which the sealing part 10 is due of the pneumatic or hydraulic pressure and allows excess pressure to escape.
  • the holding part has the shape of a crown cap 12, which is held in place by crown-shaped indentations 13 on the bead 4 of the bottle neck 1 and thereby engages with a fitting 14 formed by an indentation on the upper edge 6 of the bottle neck 1 supports, whereby their position in relation to the bottle neck is precisely defined. In this position, the crown cap 12 is not tightly connected to the bottle neck 1.
  • the plate 15 forming the sealing part, which is centrally connected via a support 16 to a bottom 17 of the crown cap 12. At its edge, the plate 15 has a circumferential sealing lip 18 which bears against the upper edge 6 of the bottle neck 1. Plate 15 and sealing lip 18 are made of an elastically resilient material and so thin that the outer edge of the plate 15th yield and the circumferential sealing lip 18 can stand out, so that excess pressure can escape.
  • the crown cap 12 can consist of sheet metal in a conventional manner, while in particular the plate 15 with the circumferential sealing lip 18 consists of a plastic material. Another material, for example sheet metal, is also possible.
  • the sealing part 2 is designed in principle as in the exemplary embodiment according to FIG. 2, but a bottom 19 of the holding part 2 is provided, similar to the bottom 17 in the exemplary embodiment according to FIG. 3 To ensure escape of excess pressure through the holding part 2, a hole 20 is provided in the bottom 19.
  • a support 21 which is connected via a spherical snap connection 22 to a plate 23 which corresponds to the plate 15 in Fig. 3 and consists of a resilient material, so that in particular the edges of the plate 23 at excess pressure can lift off the edge 6 of the bottle neck 1.
  • the base 19 it is also possible to design the base 19 to be very thin and resilient, so that it forms the spring element, in which case the plate 23 can be rigid.
  • the bottom 19 and plate 23 can be elastically flexible in the desired manner.
  • the holding part 2 is designed essentially as in the exemplary embodiment according to FIG. 4, but a rigid, disk-shaped sealing part 24 is provided, which is resiliently supported on the base 19 by elastic spring lips 25.
  • a circumferential collar 26 extends inward from the stop 5 and engages behind the outer edge of the sealing part 24, so that the sealing part 24 is captively connected to the holding part 2.
  • the fifth exemplary embodiment in FIG. 6 largely corresponds to that according to FIG. 5 with the difference that instead of the sealing lips 25 in the space between the bottom 19 and the sealing part 24, a spring rod 27 is arranged in the form of a pre-curved leaf spring.
  • the dimensioning and curvature of the spring rod 27 defines the spring force, which determines the excess pressure at which the sealing part 24 rises in order to allow excess pressure to escape.
  • the sixth exemplary embodiment in FIG. 7 largely corresponds to that according to FIG. 3.
  • a difference is that instead of the flexible plate 15, an essentially rigid sealing part 28 is provided, which is located on the bottom 17 of the crown cap 12 via an elastically flexible foam part 29 supports.
  • the foam part 29 can simply be glued to the adjacent surface parts, so that the sealing part 28 is firmly and captively connected to the base 17 and thus to the crown cap 12.
