Definitions

  • the invention relates to a method for producing a plastic closure cap for bottle-like containers, in particular a screw cap, according to the preamble of the claim.
  • the sealing washer can consist of rubber, cork, aluminum or plastic. Drip devices, pourers or the like can be arranged in the bottle mouth of the bottle-like container.
  • the contents of the bottle-like container can attack the adhesive layer or the adhesive, so that the adhesive connection is also loosened here, which also reduces the sealing effect or completely eliminates it.
  • the object of the invention is to ensure the fixing of a disc-shaped seal made of rubber, cork or plastic without radial play on the cover of the closure cap, with conventional adhesive fastenings with the disadvantages described at the outset being avoided.
  • this cap can be sterilized with this, even after being screwed onto a bottle-like container, without the connection between the sealing washer and the cap being impaired.
  • the type of filling material also has no influence on the firm connection between the sealing cap and the sealing washer.
  • a sealing washer 6 is fixed by projections 5 of a wall ring 4.
  • the inserted sealing washer 6 is held in place by means of a suitable tool (not shown) that the projections 5 are pressed out from the wall ring 4 at appropriate distances.
  • the projections 5 With the help of the projections 5, the inserted sealing washer is captively attached and pressed onto the cap base 2.
  • the diameter section according to FIG. 2 through an exemplary embodiment shows the screw cap 1 without an inserted sealing washer.
  • the screw thread 3 serves to connect the screw cap 1 to a bottle-like container (not shown).
  • the wall ring 4 arranged on the inner wall 8 of the cap, which is preferably formed in one piece with the cap 1, has a radial height that is equal to or less than the radial height of the threads of the thread 3.
  • Fig. 3 the screw cap 1 is shown with the inserted and clamped sealing washer 6 in the same diameter section as in Fig. 2.
  • the design is such that the projections 5 have a smaller radial distance than the outer diameter of the bottle mouth of an associated container. This ensures that only the sealing washer 6 comes to rest on the container mouth and provides a secure seal when the screw cap 1 is screwed on.
  • the sealing disk 6 can be made of rubber, cork, aluminum or plastic or the like and may also have a central (not shown) projection which engages in the mouth-like opening of the bottle-like container or a spout or a drip device in the mouth of the bottle-like container.
  • the invention enables the use of sealing disks 6 with standardized dimensions in likewise standardized screw caps 1.
  • the screw thread 3 can have one or more gears.
  • the radial height of the wall ring 4 is less than or equal to the radial height of the ribs of the thread 3.
  • the screw cap 1 can have gripping ribs known per se (not shown).
