Definitions

  • the present invention relates to a closure system for a container, in particular an oil filter module or an oil pan in a motor vehicle, according to the preamble of claim 1.
  • the invention also relates to a drain plug for such a container.
  • a drain plug in particular on a container of a motor vehicle, such as an oil pan or an oil filter module, known drainage screws are provided with a so-called anti-rotation lock.
  • latching hooks are provided, which produce a positive connection with a complementarily shaped recess on a housing.
  • relaxation which is understood to mean a time-dependent voltage drop. This can cause the latching hooks to slide out of the associated recesses and thus fail the anti-rotation lock. In this case, if the same drain plugs are re-installed after draining oil, a failure is likely.
  • the present invention therefore deals with the problem of an improved or at least for a closure system of the generic type to provide an alternative embodiment, which is characterized in particular by a simple yet reliable Losdussch, which also ensures that a drain plug is replaced at regular intervals.
  • the invention is based on the general idea to provide a novel closure system in a container, for example.
  • the anti-rotation lock is inventively designed such that they on the one hand Unintentional release of the drain plug reliably prevented and secondly ensures that each drain plug can only be used once.
  • this is realized by a release device with a predetermined breaking point.
  • the drain plug can also have a thread with a self-loosening thread.
  • the anti-rotation lock has at least one extending in the circumferential direction and radially to a screw head of the drain screw spaced arm, which cooperates with an undercut at a receiving opening of the container.
  • the at least one arm is resiliently formed at least slightly radially outward and is pulled when screwing the drain plug into the receiving opening on the associated undercut until the drain plug reaches its final screwed.
  • Einschraubposition now locked the Losdusschêt by the at least one arm engages behind the associated undercut at the receiving opening. If the drain plug is turned on, the at least one arm can not be released from the undercut, but caulked on this and breaks off at a predefined torque.
  • the predetermined breaking point is provided at a connecting region of the at least one arm with the screw head of the drain plug and realized by a cross-sectional weakening. Due to the fact that the drain plug together with anti-rotation, ie in the present case together with the at least one arm is preferably formed as a one-piece plastic injection molded part, the predetermined breaking point can be relatively easily realized by a material constriction or a cross-sectional weakening, on the one hand strong enough to the drain plug in to hold in its locked position in the screwed state, however, when unscrewing breaks and thereby prevents re-screwing with a re-fixing.
  • the drain plug at least two arms, in a preferred embodiment, in particular three arms, which are distributed uniformly over the circumference.
  • the Loscordrustsch has a total of two or three arms, which is why two or three associated undercuts are provided on the receiving opening.
  • a redundant anti-rotation lock can be realized, in which several arms and associated undercuts form the anti-rotation lock, so that even with a non-fully functional arm, the other arm or the other arms of the anti-rotation lock ensure a reliable fixing of the drain plug in the receiving opening.
  • the drain plug in its screw head an engagement contour for a tool, eg. For an Allen wrench, on, wherein the engagement contour, for example, can be designed as hexagon socket.
  • the engagement contour will then be made in the plastic injection molding of the drain plug together with this in a single step.
  • the drainage screw according to the invention can be completely formed with the anti-rotation lock, that is, for example, the three arms, as a one-piece plastic injection molded part and thereby on the one hand high quality and on the other hand are produced inexpensively.
  • the invention is further based on the general idea to provide such a drain plug for sealing a container with a release device and the predetermined breaking point, wherein the drain plug preferably additionally has a thread with a self-loosening thread.
  • the drain plug is held in a workshop area or in the original equipment and replaced completely due to the breaking point when loosening predetermined breaking point after each unscrewing.
  • a re-screwing the drain plug is reliably prevented by the thread with the self-loosening thread, as this prevents the fixing of the drain plug in the associated threaded receptacle.
  • a high level of maintenance quality can be ensured, especially in the case of service.
  • an inventive closure system 1 for an unspecified container eg. An oil filter module or an oil pan in a motor vehicle, a drain plug 2, in particular an oil drain plug, which has an O-ring seal 3 for sealing the closure system 1.
  • this drain plug 2 now has a release device 4 with a predetermined breaking point 5 and preferably a thread 6 with a self-releasing thread 7.
  • the self-loosening of the thread 6 is realized by a relatively steep thread 7, which is so steep that the usually screwed from below into a threaded receptacle 8 of the closure system 1 drain plug 2 turns out automatically due to their gravity again automatically.
  • the closure system 1 functions as follows: First, the drain plug 2 is inserted into the receiving opening 12 and then screwed by screwing into the threaded receptacle 8. Until reaching an end position, the arm 10 or the arms 10 are pulled over the associated undercut 11 or the associated undercuts 11 in the receiving opening 12 in the last turns before reaching the end position. When reaching the end position lock the individual arms 10 in the associated undercuts 11, thereby reliably preventing loosening becomes. If now the drainage screw 2, for example. In an oil change, are removed, a corresponding opposite torque is applied via the engagement contour 13 until the predetermined breaking points 5 of the arms 10 break and thereby allow easy removal of the drain plug 2 from the threaded receptacle 8.
  • a renewed screwing the drain plug 2 into the threaded receptacle 8 is conceivable, due to the self-releasing thread 7, 7 'holds the re-screwed drain plug 2 but not because they can not support their arms 10 on the undercuts 11. Rather, in the present case due to the specially designed thread 7, 7 'already the gravity of the drain plug 2, to automatically unscrew them from the threaded receptacle 8 again.
  • the inventive anti-rotation lock 4 with the predetermined breaking point 5 and at the same time the self-releasing thread 7, 7 'thus insertion of a new drain plug 2 can be forced at a discharge of the fluid, which in particular the maintenance and service quality can be significantly increased as a Verbau already used drain plugs 2 can be reliably prevented.
