    Threaded plug with a sealing ring Known technique
    The present invention relates to a threaded plug having a sealing ring, the threaded plug comprising a head and a threaded part, where a flange is formed between the head and the threaded part to cooperate with the sealing ring mounted on the side of the flange facing the threaded part.
    Threaded plugs are widely used for reliable closure of filling and emptying openings in e.g. water and oil tanks, hydraulic cylinders and more. The threaded plugs are screwed into openings in containers to close the openings. The openings are equipped with a thread corresponding to the thread on the threaded plug.
    Generally, there is a large selection of threaded plugs made in various sizes and shapes and in various materials. These may include sealing rings such as must be heated for adaptation or there may be loose sealing rings.
    Purpose of production
    The object of the present invention is to provide a threaded plug with improved properties, especially with respect to tightness. The threaded plug according to the invention is also easy to manufacture.
    The present invention thus relates to a threaded plug having a sealing ring, the threaded plug comprising a head and a threaded part, where a flange is formed between the head and the threaded part to cooperate with the sealing ring mounted on the side of the flange adjacent to the threaded part. and wherein the flange is provided with a projection extending continuously throughout the entire face of the flange facing the sealing ring.
    The head of the threaded plug may be designed in various ways according to the specific application. For example, the head may be configured as a hexagonal head such that the threaded plug can be tightened or loosened with a wrench or the head may be provided with a notch so that the plug can be tightened or loosened with a screwdriver.
    The threaded member is preferably cylindrical and threaded on the outer surface. Both the cylindrical portion forming the threaded portion and the head may be hollow or of solid material. The thread is designed so that it corresponds to the thread in the openings that the threaded plug must close.
    The threaded plug and seal ring are interconnected and interconnected units, although it will be possible to separate them. Where the threaded plug and sealing ring are molded in a workflow in the same mold, and thus constitute a total unit, the projection will assist in forming the portion of the sealing ring which abuts the flange.
    In some embodiments, the sealing ring may be releasably attached to the threaded plug.
    The threaded plug with a sealing ring according to the invention contributes to a better seal when containers are closed with the plug. This is due to the special design of the flange with a protrusion extending continuously on that of the two faces of the flange facing the sealing ring. The protrusion can also be considered as a bulge on the flange that can press against a support. As a result, the flange with protrusions can press harder against a substrate in the form of a sealing ring or gasket when the threaded plug is screwed into an opening to be closed, thereby ensuring an effective seal around the opening.
    The flange typically has an annular or circular shape and has an extension extending approximately perpendicular to the center shaft of the cylindrical portion of the threaded plug. Since the flange is circular or annular, it is preferred that the projection of the flange extend in approximately circular form. The flange may, of course, be provided with several projections which may then lie as rings within each other on the surface of the flange.
    The projection extending on one face of the flange may in principle have any desired shape or cross-section. The cross-section can take the form of a semicircle, square, triangle or the like. In some embodiments, it is preferred that the cross-section be of a triangular shape which causes the protrusion to have a tapered shape, which allows the protrusion to be effectively pressed against the sealing ring.
    In order to obtain the best sealing with the threaded plug, it is preferred that the flange and sealing ring have similar sizes, that is, sizes so that they can cover each other.
    In a preferred embodiment of the threaded plug with a sealing ring, the sealing ring has a thickening of at least one face, and preferably the sealing ring has thickening on both of the opposing faces. The thickening may help to seal against liquids that penetrate under the thread plug from the environment, e.g. paint, varnish or the like, which can seep under the flake and seal ring and make it difficult to loosen the threaded plug when required.
    In order to obtain the best seal against penetrating liquids, it is preferred that the thickening or thickening extend substantially annularly and preferably along the entire outer periphery of the sealing ring. This provides a good seal along the periphery of the threaded plug, which can also prevent fluids from seeping in under the flange and seal ring. In principle, the thickening is a local area of the sealing ring, where the material thickness is increased so that the sealing ring appears thicker in this area. Of course, it is possible to provide embodiments of the sealing ring where it has several such thicknesses which may lie as rings within each other on the faces of the sealing ring.
    Where the sealing ring is loosely mounted on the threaded plug, it is advantageous that the sealing ring comprises means for holding it on the threaded plug. The agents may e.g. be projections in the central opening of the sealing ring which can clamp on the threaded plug and thereby retain the sealing ring approximately fixedly on the threaded plug.
    Alternatively, the threaded plug may comprise means for holding the sealing ring. The means for retaining the sealing ring may be protrusions, jaws, protrusions or grooves. That is, the threaded plug can be provided with projections or jaws on its surface which protrude in pairs and grip the sealing ring. In the region adjacent to the flange where the sealing ring is located, the threaded plug may be provided with several such pairs of protrusions or jaws spaced circumferentially on the threaded plug. For example, 4, 6 or 8 pairs of protrusions or jaws may be placed on the threaded plug.
    In some embodiments, the sealing ring may be designed to engage the outgrowths or jaws. For example, it may be thinned in the region toward the central opening so that it can fit into the space between the outgrowths or jaws.
    It is also possible to retain the sealing ring on the threaded plug by locally increasing the diameter of the threaded plug. It will typically be an area of the threaded portion adjacent to the flange. Such a solution, like the use of protrusions, jaws and the like, can also serve to center the sealing ring on the threaded plug.
    The threaded plug can be made of metal or plastic or possibly ceramic. Metal can e.g. be it iron, brass, stainless steel or aluminum. Preferably, the threaded plug is injection molded in a plastic material, e.g. polyamide or PEFID possibly. together with the sealing ring in the same tool and wherein the sealing ring is generally made of a thermoplastic material which is flexible in use, e.g. TPE, rubber or nitrile rubber.
    The sealing ring is made of all materials suitable for use in gaskets. Both the threaded plug and the sealing ring can be fiber reinforced.
    The drawing
    The invention will be explained in more detail below with reference to a drawing, in which figure 1 shows an embodiment of the threaded plug seen in perspective, figure 2 shows a sectional view of the threaded plug, figure 3 shows a section of the threaded plug, figure 4 shows another embodiment of the threaded plug seen in perspective, figure 5 shows a sectional view of the threaded plug of figure 4, and figure 6 shows a section of the threaded plug.
    Description of the Examples
    Figure 1 shows a threaded plug 1 with head 2 and threaded part 3. The threaded plug 1 is provided with a sealing ring 4, which is adjacent to the flange 5. The flange 5 is provided with a projection 6 on the surface facing the sealing ring 4.
    This protrusion 6 shows that the sealing ring 9 remains within the protrusion when the clamping occurs, thereby contributing to an increased sealing pressure between the parties and thus a secure seal.
    In this embodiment, the threaded plug may be provided with projections or jaws 7 for retaining the sealing ring 4 on the threaded plug 1.
    The jaws 7 are better seen in Figure 3, which is a section of Figure 2. Here, it is seen that the jaws 7 are located in extension of the threaded part 3 just below the flange 5, so that the sealing ring 4 abuts against the flange 5. In figure 3 the projection is seen. 6 on the surface of the flange 5 also clearly.
    In Figure 3 it is also seen that an area 4a of the sealing ring 4 which engages the jaws 7 is shaped to fit in the jaws.
    Figure 1 is a perspective view showing the threaded plug 1 with head 2 and threaded portion 3 with sealing ring 4 mounted adjacent the flange 5.
    Figure 4 shows an alternative embodiment of a threaded plug 10 according to the manufacture with head 12 and threaded part 13. The threaded plug 10 is provided with a sealing ring 14 which is adjacent to the flange 15. The flange 15 is provided on the surface facing the sealing ring 14 with a projection 16, as shown in FIG. 4 and 5.
    This protrusion 16 ensures that the portion 19 of the sealing ring abutting the plate 15 remains within the protrusion 16 as the partner is clamped. This ensures that an effective seal is obtained between the parties so that the sealing member 19 is prevented from being pressed outwards, but is pressed against the flange.
    In this embodiment, the sealing ring 14 may have additional thicknesses 18 on both of its opposite surfaces. The thicknesses 18 are clearly seen in Figure 6. The thicknesses 18 are provided in the outer periphery of the sealing ring 14. That is, when the threaded plug 10 is used to close an opening, the flange 15 will press down against the sealing ring 14 and the thicknesses 18 and tighten. this way causes an extra good seal along the outer edge of the flange 15 so that paint or the like that is subsequently applied does not penetrate under the flange 15.
    As can be seen in Figure 4, in this case the sealing ring 14 is retained by the threaded plug 10 by means of a series of projections 19 in the central opening of the sealing ring 14. The projections 19 clamp against the threaded plug and retain the sealing ring 14 in its position.
