Definitions

  • the invention relates to a bottle screw cap according to the preamble of claim 1. Furthermore, the invention relates to a bottle including a bottle screw cap.
  • the object of the invention is to provide a bottle screw cap suitable for mass production, which can be screwed onto the bottles in a filling line and integrated into the process cycle without the need for separate preassembly with the joining together of two or more components in a predetermined manner mutual position.
  • the closure only has two parts that can be placed on a bottle neck in any relative rotational position
  • the assembly process can be assembled on normal assembly stations with relatively simple means and inserted directly into a filling line, without the cycle time having to be changed or manual work being required.
  • Both the pressing of the insert into the bottle neck and the placement of the closure cap on the bottle neck can take place in any rotational angle position, so that no complicated measures are necessary to give the parts a mutual, predetermined, matching position for joining.
  • a spring tongue sliding past a cam can generate a rotational resistance and an acoustic signal that signals to the user shortly after the beginning of the turning process in the bottle opening direction that the bottle is open and in the opposite direction of rotation the user is informed that the bottle is open shortly before reaching the end position the bottle is closed again.
  • a blow molded plastic bottle 1 contains a bottle neck 13 provided with a flat external thread 12.
  • This thread 12 is a double high helix thread with a flank angle of preferably approximately 12.5 °.
  • an insert 16 made of plastic with a press fit is inserted in any angular position, so that it is held against rotation by friction.
  • This insert 16 contains a round closure head 18, which - according to FIG. 5 - is rigidly connected to an inner sleeve wall 14 with at least one, preferably with three mutually angularly offset webs 20. In between there are free openings 22 to the sleeve interior 23 and to the inside of the bottle 1.
  • the sleeve inner wall 14 is tightly connected to the sleeve outer wall 17 by a truncated cone part 15.
  • the bottle 1 is provided at the transition between the bottle neck 13 and the actual bottle body with a shoulder 27 which deviates from the circular shape, as can be seen from FIGS. 2 and 3.
  • cams 30 which, in conjunction with the closure cap 2, cause a latching in the closed position and an acoustic signal generation.
  • the position of these two diametrically opposite cams 30 is offset by 45 ° relative to the adjacent stop edge 25.
  • the closure cap 2 made of plastic contains a slightly conical outer jacket 8, as well as a concave cap end wall 5, which is provided with a central, circular outflow opening 7.
  • a threaded part 10 with an internal thread protrudes from the cap end wall 5, which is intended to cooperate with the external thread 12 of the bottle neck 13.
  • a cylindrical sleeve 11 extends from the cap end wall 6 in a coaxial arrangement to the threaded part 10 into the interior of the closure cap 2.
  • the diameter of the sleeve 11 is smaller than that of the threaded part 10, so that there is an annular space 19, in which in the assembled state the outer wall 17 of an insert 16 engages and is full against the inner wall of the bottle neck, ie with a press or adhesive fit.
  • the immersion depth of the insert 16 is limited by an annular shoulder 21, which comes to rest on the end face of the bottle neck 13 in the assembled state.
  • the inner wall 14 of the sleeve 11 lies tightly against the inner wall of the insert 16. It is expedient for one of the walls lying against one another to be provided with a sealing annular bead 31, the parts lying against one another having to be rotatable relative to one another.
  • the closure cap 2 contains two resilient lamellae 28, which protrude from the inside of the casing 8 and are inclined at an angle of approximately 45 °, in such a way that they close to the end of the screwing process on the closure cap Bottle neck clockwise - that is, in the direction of arrow A - be flexibly bent against the inner wall and thereby pass the stop edges 25 or this is caused by an oval deformation of the jacket 8.
  • the slats then spring back into the original position, or the jacket 8 springs back into the circular position.
  • the lamellae 28 come to rest against the stop edges 25.
  • the available angle of rotation of the closure cap 2 is limited to approximately 90 ° by the stop edges 25.
  • the closure cap 2 also contains at least one, preferably two diametrically opposed, axially directed spring tongues 32, which are fastened in the upper part between the inner wall of the casing and the threaded part 10, which, however, can swing freely in the lowest region.
  • spring tongues 32 interact with the two cams 30 protruding from the bottle shoulder 27. If the closure cap 2 is rotated, there is resistance and an acoustic noise when the spring tongues 32 are passed over the cams 30. This signals to the user a rotational position shortly before the end rotational position of the closure cap 2 and when rotating in the other direction, a resistance and an acoustic signal also arise shortly after the rotation begins.
  • Bottle 1 itself is usually designed as a squeeze bottle made of flexible plastic, so that the contents of the bottle can be squeezed out by hand.
  • the jacket 8 deforms into an oval or the flexible, inclined slats 28 bend, which thereby reach behind the stop edges 25.
  • the jacket or the slats then return to their original shape or inclined position due to their elasticity. Together with the stop edges 25, they prevent the entire closure from being unscrewed. This makes it a "childproof" Closure achieved in the sense that an unintentional, full turning back and unscrewing of the entire closure beyond the opening position is prevented. This prevents accidental unscrewing and thus leakage of the bottle contents through the full bottle neck opening.
