Definitions
- This invention relates to a screw cap, in other words to a cap intended to be applied to all kinds of packings, containers and the like, which packings are capable of containing any products whatsoever such as all kinds of liquids, petrochemicals, etc.
- an object of the present invention is a screw cap which is carried out in such a way that the sealing function of packings, containers and the like, irrespective of the product placed in them, occurs optimally.
- the screw cap of the present invention is constituted by an annular body which is screw threaded and at one end is provided with a sealing wall, characterized thereby that at the internal side of said sealing wall an annular projection is provided whose outside diameter is determined with respect to the inside diameter of the connecting orifice of the container with which such screw cap has to co-operate, whereas in the vicinity of said sealing wall the inner side of said annular body possesses a cylindrical part, whose diameter corresponds with the outside diameter of the sealing orifice of the container with which the screw cap has to co-operate while, finally, a small rib is provided at the inner side of said sealing wall between the inner side of said annular body and the outer side of said annular projection, which rib can co-operate with the upper rim of the sealing orifice of said container.
- a screw cap according to the present invention is represented consisting of the proper screw cap 2 and a removable sealing rim 3.
- the screw cap part 2 mainly consists of an annular body, preferably provided at its outer side of grooves or ribs 4 for improving the grip on such screw cap, while its inner side is provided with a suitable screw thread 5, which corresponds with the screw thread provided on the container or the like, with which such screw cap has to co-operate.
- this annular body as usual is closed by a wall 6, which according to the present invention possesses inside a cylindrical wall part 7 the diameter of which is accurately determined with respect to a cylindrical wall part of the orifice of the container with which such screw cap has to co-operate on the one hand, and an annular projection or rib 8 applied to the inner side of wall 6 on the other hand, the diameter of which projection or rib is also accurately determined with respect to the inner diameter of the orifice of the container with which the screw cap has to co-operate, both elements being located such, that the distance a between the walls 7 and 9 is equal to or somewhat smaller than the thickness of said orifice of the container.
- the free end of this rib 8 preferably is rounded, at least at its outer side.
- third sealing means a small lip 10 at the inner side of wall 6 and between the walls 7 and 9, the cross-section of which lip has a triangular form, more especially according to a preferred embodiment the form of a scalene triangle, both features being such, that the upper wall of the orifice of the container that has to co-operate with such screw cap after the latter has been applied, comes into contact with said small lip as will appear below.
- the annular body of the screw cap proper is connected by means of small connecting lips 11 with the aforementioned ring 3 wich internally has a stop-forming rib 12 that can co-operate with the corresponding rim of the container or the like so as to obtain that for unscrewing screw cap I, the sealing rim 3 has to be removed first, which is possible by tearing it off all round starting from a determined place, which for that purpose is provided with a projecting lip 13.
- the orifice 15 on top of it has a wall part 18, which is completely cylindrical, while also the inner wall 19 of said orifice 15 is truly cylindrical, both features being such that these walls 18 and 19 co-operate completely sealingly with the walls 7 and 9 of the screw cap when this is screwed on, whereas a third sealing is obtained by rib 10, which co-operates with the upper rim 20 of the orifice 15 when the screw cap is screwed home.
