Definitions

  • the invention relates to a closing cap, especially for the nozzle of a container of synthetic material, said cap consisting of a closing wall, which is perpendicular to the centre line of the nozzle, of a cylindrical outer casing, directed away from this wall, which encloses the nozzle and which is provided with internal screw thread or such-like means, and of a sealing means which by turning the cap can be clamped between the cap and the nozzle.
  • Such closing caps are used at a large scale for closing the nozzle of so-called jerrycans.
  • the problem occurs that no complete sealing can be obtained when the nozzle is provided with external screw thread and the cap with internal screw thread, as the nozzle only can have a limited wall thickness, so that also the force with which the cap is screwed on the nozzle must remain limited.
  • the sealing means in the shape of a disc of flexible material which is pressed between the end rim of the nozzle and the closing wall of the cap, is often not compressed enough to assure a permanently good sealing.
  • a closing cap which is characterized in that the outer casing by the screw thread or such-like means co-operates with an outer cylindrical push ring, which in the position of use of the cap is at least partially within the outer casing and which is provided with an inwards directed collar at the end which is turned away from the closing wall of the cap, between which collar and the closing wall of the cap an outer sealing sleeve is accomodated, which when the cap is used is slid over the outer wall of the nozzle and prevents the ring from turning with respect to the nozzle, in such a way that by turning the cap the push ring can be brought towards the closing wall for the longitudinal compression of the sealing sleeve so as to lie at least against the outer wall of the nozzle, the cap furthermore being provided with a cylindrical inner casing and with an inner push ring around it, which casing and ring by means of screw thread or such-like means co-operate with one another, said inner push ring being
  • German Offenlegungsschrift 1 ,429,908 which describes a closing cap, especially for thermos flasks, with which use is made of a sealing sleeve, which is provided between two discs, which can be drawn towards one another to press the sealing sleeve outwards against the inner wall of the nozzle of the container.
  • a sealing sleeve which is provided between two discs, which can be drawn towards one another to press the sealing sleeve outwards against the inner wall of the nozzle of the container.
  • the closing wall of the cap is provided with two co-axial cylindrical collar sections between the outer casing and the inner casing thereof, which sections are positioned in such a way, that between the two collars the upper part of the nozzle can be received and between each of the collars and the adjacent casing the upper part of the push ring concerned, the sealing sleeves lying against the head surfaces of the collars.
  • the outer push ring can be provided with an outwards directed collar near the inwards directed collar, the outer circumference of which comprises a toothed part, which can co-operate with the toothed part of a checking ring, which by means of tear-off sections is connected with the outer casing of the cap, the teeth of the co-operating toothed parts being of such a shape, that when the cap is screwed tightly on the nozzle of a container, the teeth snap over one another, whereas when the cap is unscrewed, the teeth will grip into one another and the checking ring will be torn off the cap.
  • the toothed parts are provided on axial, oppositely located surfaces of the collar of the push ring and of the checking ring connected with the outer casing.
  • the toothed parts are therefore provided on axial cylindrical surfaces, which when the cap is turned will slide somewhat along each other, which in itself provides no problems.
  • the space between the closing wall of the cap and the inner casing can be used in a favourable way for accomodating an air bleed valve, which in certain cases is desirable or required to prevent the pressure in the container from becoming too high.
  • Said space may e.g. also contain a foam material which is absorbing and/or resilient.
  • the nozzle of a container is indicated by the reference number 1; on this nozzle the closing cap 2 is mounted.
  • the closing cap 2 consists of the closing wall 3 with the outer casing 4 and the inner casing 5 perpendicular thereto. Between the outer casing 4 and the inner casing 5 the collars 6 and 7 are provided.
  • the outer casing 4 is provided with internal screw thread 8 and the inner casing 5 with external screw thread 9.
  • the thread 8 the external thread 10 of a push ring 11 co-operates, which ring is provided with an inwards directed collar 12, between the collars 6 and 12 a resilient sealing sleeve 13 being provided.
  • a screw thread 14 of an inner push ring 15 co-operates with the screw thread 9 of the inner casing 5.
  • the push ring 15 is provided with an outwards directed collar 16 and between the collars 7 and 16 there is an inner resilient sealing sleeve 17.
  • the push rings 11 and 15 are screwed into the casing 4 and 5, respectively, whereas simultaneously the sealing sleeves 13 and 14 are mounted.
  • the push rings 11 and 15 are screwed in so far, that the sealing sleeves 13 and 17 are bent slightly towards one another, so that when the closing cap is placed on the nozzle 1, the sealing sleeves 13 and 17 are lying resiliently against the wall of the nozzle 1.
  • the closing cap 2 has been pressed on the nozzle 1 so far that the upper edge of the nozzle 1 is located between the collars 6 and 7, the closing wall 3 with the outer casing 4 is turned, the push rings 11 and 15 being prevented from turning by their co-operation with the sealing sleeves, which press firmly against the wall of the nozzle 1.
  • the push rings 11 and 15 will thereby move inwards in the cap and press the sealing sleeves more firmly against the wall of the nozzle 1.
  • sealing sleeves 13 and 17 The way of deformation of the sealing sleeves 13 and 17 will be dependent on the original shape thereof and on the properties of the material of which the sleeves are made. Therefore it is possible, in contrast with the drawing, that the sealing sleeves remain lying over their entire length against the corresponding push ring.
  • the outer casing 4 may be provided with a checking ring 18, which by means of small lips 19 is connected with the outer casing 4.
  • the inner surface of the checking ring 18 is provided with teeth 20, which co-operate with teeth 21, provided on the outer surface of a collar 22 of the push ring 11.
  • the teeth 20 and 21 have such a shape and are made of such a material, that when the casing 4 is turned together with the checking ring 18 in the direction of the arrow P, the teeth 20 of the ring 18 will snap over the teeth 21 of the collar 22.
  • the teeth 20 will be held back by the teeth 21, so that on the ring 18 a holding force will be exerted and the lips 19 between the ring 18 and the casing 4 will be torn.
