Definitions

  • caps are made of plastic for closing containers, especially of bottles, widely used.
  • Many embodiments of caps have a so-called guarantee tape, which is detachable and when opening the bottle from the cap is torn off. As long as the guarantee tape is in undamaged condition small webs is connected to the actual cap, this shows the original condition of the bottle contents. It is thus guaranteed that the Cap in the original condition attached to the bottle neck, preferably screwed on, is.

  • Bottles are basically screwable caps for closing Bottles, especially for closing so-called reusable bottles.
  • Such bottles are used for bottling beverages of all kinds, in particular also carbonated drinks are bottled. So it must be there used cap also the gas pressure created within the bottle withstand, must therefore be gas-tight with the bottle or against the bottle.
  • PET bottles have been on the market for some time now, but it is here is reusable plastic bottles, which in particular with a filling volume of 1.5 liters are offered. Due to considerable tolerances of the one in question Bottles in the area of the bottle mouth exist compared to those to be used Caps special sealing problems. Consequently, caps are here with special sealing measures required. On top of that, the ones in question PET bottles, especially when used multiple times, do not have perfect mouths and threads have more, especially since they are handled by consumers and fillers are mostly deformed or damaged.
  • the gas pressure building up the bottle is used in a particularly advantageous manner for pressing on the inner seal to the inside wall of the bottle, the one at the free end of the Internal seal formed bead due to the considerable distance from the end wall is pressed against the inside of the bottle with enormous pressure.

Thereafter, the closure cap according to the invention is equipped such that the end wall in the area between the cap wall and the inner seal one of the End wall protruding, at least slightly inclined towards the inner seal has an annular wedge seal.
  • a sufficient seal between the cap and the Bottle to be closed can be realized in that between the inner seal and the cap wall due to its wedge-shaped configuration as a wedge seal designated seal is formed.

  • Guarantee tape closes to the cap wall on the side facing away from the front wall and has a first predetermined breaking point.
  • This Guarantee band is however problematic in that when opening the bottle, i.e. when unscrewing the Closure cap, the guarantee band first broken and used by numerous users is torn off the cap altogether. After use, i.e. after emptying the Bottle, this torn guarantee band often migrates into that Bottle interior, from which it is difficult due to its curved design is removable. During the cleaning process of the bottle, those that get inside the bottle can be removed Guarantee tapes cannot be rinsed out. So-called bottle inspection machines do not recognize these tapes, which often means that such old - used - Put the guarantee bands in a drink that has been refilled into the reusable bottle. Complaints are preprogrammed here.

  • the radius of the shoulder 17 is preferably 0.25 mm and is selected so that the sealing lamella 16 from the highest point of the shoulder 17 to the top the slat 16 runs at an angle a.
  • Extensive comparative tests have shown that the angle ⁇ should preferably be no more than 35 ° and no less than 25 °, and according to a particularly preferred embodiment should have 28 °.
  • the shoulder 17b acts Sealing lamella 16b with the inside of the bottle 100 in the closed state together, by actuating the locking mechanism 12b the sealing lamella 16b is deflected from its rest position and bent towards the inside of the bottle.
  • the small effective surface of the Sealing lamella 16b (which is essentially through the tip region of the shoulder 17b is specified) a comparatively high sealing pressure is reached, which is caused by the Return torque of the deflected sealing lamella 16b is defined.
  • the closure flap according to the invention can be made from different materials become. If the sealant 11 (together with the shoulders 14b and 34a-f and the elastic slat 16b) provided as an integral part of the cap, suitable especially polyethylene as a cap material.
