Definitions
- the invention relates to a closure cap for screwing and / or pressing onto the pouring spout of a container, in particular a bottle, with an in particular annular coaxial sealing lip fastened in the bottom of the cap, which extends into the socket when the cap is attached.
- the object of the invention is to improve a closure cap of the type mentioned at the outset such that the additional annular sealing lip achieves a high sealing pressure by applying, in particular, screwing on the cap, so that even high internal pressures in the container are withstood.
- the sealing lip between its upper and its lower end is curved outwards and / or kinked in such a way that when the sealing lip is compressed in the axial direction, the curvature and / or kink moves further outwards and the outside of the Sealing lip sealing against the inner wall of the nozzle.
- the construction is simple and a reliable function is achieved, even if it is screwed on several times.
- the annular kink or an annular outer region of the curvature forms the seal with the inner wall of the connector.
- the pouring spout has at least one bearing surface on its inner wall, on which the lower end of the sealing lip abuts. As a result, the compression of the sealing lip is reliably achieved and the lower end of the sealing lip forms a further seal with the contact surface.
- the contact surface is preferably ring-shaped.
- the support surface can also be formed by at least two projections on the inner wall of the pouring spout.
- the sealing lip have at least two kinks.
- a better mobility of the sealing lip at the connection point to the cap base is achieved if this upper connecting point between the sealing lip and the cap base has a material weakening, in particular a reduction in the thickness of the sealing lip.
- a precise, defined sealing surface in particular a sealing line, is achieved if the inner surface of the connecting piece and / or the outside of the sealing lip has / have a raised location, in particular an annular bead, as an abutment for the sealing lip. It is preferably proposed that the axial extent of the sealing lip be 30-100% of the height of the cap. The distance between the support surface and the upper end of the nozzle should be smaller than the axial length of the sealing lip.
- Fig. 1 shows a sealing lip with a circumferential kink
- Fig. 2 is an outwardly curved sealing lip.
- a closure cap 1 produced by injection molding from plastic has an upper horizontal base 2, on the outer edge of which a cylindrical side wall 3 is formed downwards. At the lower end of the side wall 3, an originality securing ring can be formed, which tears off when the cap is opened.
- Such a cap 1 can be screwed or pressed onto the cylindrical pouring spout 4 of a container, in particular of a container neck such as that of a bottle.
- annular sealing lip 6 is formed on the inside coaxially to the cap axis, which thus extends downward and extends into the socket 4 when the cap is in place.
- the sealing lip 6 is here radially widened outwards so that the outer circumference of the sealing lip and thus also the diameter is larger than the outer circumference and the diameter of the sealing lip in the region of the fastening point 7 of the sealing lip on the bottom 2 and also on the lower free end 8.
- this radial enlargement of the sealing lip 6 to the outside is formed by a kink 9, so that the wall of the sealing lip is similar in section to a toggle lever.
- the sealing lip 6 is curved outwards, so that the outside of the sealing lip is convex and the inside is concave.
- a coaxial stop ring 10 is formed on the inner wall of the nozzle 4, which protrudes inwards and forms a stop surface 11 for the free lower end 8 of the sealing lip 6. This ensures that the distance A of the stop surface 11 from the upper end of the nozzle 4 is smaller than the length or the height L of the sealing lip 6, so that when the cap 1 is in particular screwed onto the connecting piece 4, the end 8 of the sealing lip 6 comes to rest on the ring 10 and is compressed in such a way that the sealing lip 6 follows is pressed on the outside, that is to say increases in diameter and circumference at least in the central region.
- the curvature 12 and / or kink reaches so far that it is pressed in a sealing manner against the inner wall of the connecting piece 4.
- the inner surface of the connecting piece and / or the outside of the sealing lip can form a raised annular point, in particular an annular bead, as a defined contact and secure seal.
- the sealing lip can also have more than one kink, in particular two or three. It can also be advantageous if the upper connection point, that is to say the attachment point 7, has a material weakening, in particular a reduction in the thickness of the sealing lip, in order to thereby form a joint function.
- the stop ring 10 and thus the stop surface 11 do not have to be continuously circumferential, but the stop ring 10 can also consist of individual parts with gaps in between.
