Definitions

  • the invention relates to a rotary closure for a container mouth with a Screw cap that has at least one opening and with an between the screw cap and the container mouth arranged sealing element, that when the screw cap is closed between the screw cap and the The container mouth is clamped tightly, an additional elastic element being provided, of which at least sections are clamped in the clamping area between the clamped part of the sealing element and the screw cap when the rotary closure is closed.
  • Twist locks with screw caps are known in many forms. Frequently they serve to close a container mouth of a container with a liquid that is not in contact with for any period of time may have the outside space because it is, for example, chemicals or Foods that react with contact with oxygen. Moreover must be ensured in the event of containers accidentally or intentionally tipping over be that they do not leak easily or liquid through the closure can penetrate to the outside.
  • the twist locks have an additional sealing element.
  • This sealing element can either be a flat sealing washer be or a cup seal. In both cases the radially outer area is of the sealing element mostly designed so that it is flat on the outer edge of the (round) container mouth rests and with the screwed on Screw cap is firmly clamped.
  • the container is closed with the twist lock the manufacturer or filler of the liquid, and that by machine.
  • the twist lock with a high force of 15 Nm, for example. This makes it an absolute secure clamping and sealing of the twist lock is guaranteed.
  • the additional elastic element surprisingly solves the problem. It will by the manufacturer when closing the screw cap on the container mouth with the sealing element together between the screw cap and the container mouth is jammed.
  • the high contact pressure of 15 Nm is without more achievable and is not in any way by the elastic additional element Way adversely affected.
  • the normal "opening process would work too continue to be difficult, because compared to the previous version without the elastic element does not change at all.
  • the frictional force in tangential Direction that should be applied to make the twist lock normal and usual to turn up, is the additional elastic element in not changed in any way.
  • the grip area sections of the additional elastic element have radially outwardly directed tongues.
  • the grip area sections of the additional elastic element have a pull tab. This is especially true then when the pull tab in the unopened closed state of the twist lock Before opening for the first time using tear-off bars with the clamping area sections connected is. This ensures that on the one hand particularly easy handling for the user arises; Furthermore also an originality assurance. If the still closed original, Containers coming directly from the manufacturer are opened this way for the first time is destroyed, the additional elastic element is destroyed because the Tear bars are torn so that the pull tab by the user can be gripped and used correctly. So it is not possible at first make an opening by means of the pull tab and then by manipulation the additional elastic element back to its original Bring the place and give the impression that the container is not yet open Service. This is becoming increasingly interesting to the user's safety to give that he has a previously unopened container in front of him. The torn tear-off bars will immediately catch his eye and his suitable one Awaken suspicion.
  • the screw cap one has circumferential slot as an opening in the head plate and that central, inner area of the head plate within the circumferential slot with the outer area of the screw cap is connected via webs and in is offset axially towards the container mouth.
  • FIG. 1 shows a top view of the invention. In contrast to the usual practice, one element is shown in solid lines and a second element in dashed lines. Figure 2 shows the element in section.
  • a screw cap 10 is equipped with an internal thread 11, which is shown in FIG 2 is clearly visible in the top third of the exploded view.
  • the screw cap 10 is closed at the top by the head plate 14.
  • the top plate 14 has Screw cap 10 has a central, symmetrical central opening 15.
  • the screw cap 10 can be seen from above, in the middle Opening 15.
  • the ribs 12 outside allow manual attack and ease turning around the fictitious, central axis of rotation.
  • a sealing element 30 is shown in the lower third in FIG. 2, here one Cup seal with a cup 3.
  • the sealing element 30 is on a Container mouth (not shown) placed on closing, the Support surface 32 is placed on the top of the container mouth.
  • an additional elastic element 20 is now provided, which can be seen in the middle third of the exploded view in FIG. 2.
  • This additional element 20 is placed on the sealing element 30 so that its outer clamping area sections 21 on the area of the sealing element 30 come to rest, the underside of which forms the support surface 32.
  • the screw cap 10 can then be placed over it and screwed on become.
  • the additional elastic is first Element 20 and then the sealing element 30 in the screw cap 10 inserted and then screwed this entire construction onto the container mouth become.
  • the additional elastic element 20 in its clamping portion 21 tongues 22, either a larger number of about 10 to 20 tongues or in another embodiment also only 3, 4 or 5 tongues of larger angular dimensions.
  • These tongues 22 of the clamping area portions 21 of the additional elastic Elements 20 are closed after the twist lock the head plate 14 of the screw cap 10 and are covered for the user not visible.
  • a grip area section 23 can be seen by the user a pull tab 24, namely under the opening 15 in the top plate 14 of the Screw cap 10 is arranged ready to hand.
  • tear-off webs 25 are so thin that the user can lift them the pull tab 24 immediately tears through the tear-off webs 25 so that they only still holds on a retaining web 26.
  • the pull tabs are also moved in succession further peripheral areas of the clamping area sections 21 from the clamping pulled radially inward towards the axis of rotation of the twist lock.
  • FIG. 3 schematically shows, in section, one side of a container mouth with a screw cap 10 attached, which clearly shows what effects occur when the additional elastic element 20 is pulled out.
  • the area of a container mouth can be seen on one side.
  • the top goes into a mouth neck 41 near the container mouth over, provided with an external thread, not shown in Figure 3 is.
  • the screw cap is on the mouth neck 41 with its external thread 10 screwed with its internal thread 11 (also not shown in Figure 3).
  • the screw cap 10 is therefore parallel with its side walls to the neck of the mouth 41. This cylindrical side wall of the screw cap 10 with the internal thread 11 is closed at the top by the head plate 14.
  • a sealing element 30 here a flat gasket, with the contact surface 32 on the top edge of the Mouth neck 41 placed on the opening of the container 40.
  • Figure 3 is for better recognition of the individual elements between two elements left a small gap that does not exist in reality because as said, a seal should be made. It is still conceivable, here in addition To provide sealing layers for induction seals or the like.
  • Screw cap 10 is in the area where the head plate 14 is over the sealing washer 30 presses against the support surface 32, the additional elastic element 20th intended. On average, it is disc-shaped, similar to the flat gasket of the Sealing element 30.
  • the head plate 14 is in contrast to conventional Provide screw caps 10 with the opening 15, which is simple in FIG. 3 as missing head plate ".
  • the additional elastic element by pull tabs 24, not shown in this figure be taken. This makes it possible to apply force in the direction of arrow 28 the additional elastic element 20 or in particular on its clamping area sections 21 exercise. This force in the direction of arrow 28 goes out the clamping area above the contact surface 32 in the direction of the fictitious Axis of the mouth neck 41 of the container 40.
  • the frictional force in this Direction is relatively small because it only takes a relatively short distance.
