Definitions

  • the invention relates to a lid with an inner part, in particular for oil containers, according to the preamble of claim 1.
  • Lids of this type create a quick lock due to the bayonet connection.
  • An inner part arranged in the inside of the lid, in which locking elements are molded, is placed on the container to be closed.
  • elastic locking elements are guided on the bayonet cam track of the container and z. B. locked after a quarter turn.
  • a closure cap for an oil filler neck described in DE-B 29 17 149 has in the middle a connecting part with two opposing tongues. These resilient tongues are equipped with so-called locking lugs, over which a leaf spring with a rectangular opening is pushed. The locking lugs prevent the leaf spring from coming loose from the connecting part. To secure the locking lugs against resilient yielding, a plug is pressed into the connecting part after the mounting of the leaf spring, said plug resting on the inside of the locking lugs.
  • the mounting of the leaf spring on the connecting part is relatively complex and the assembly is cumbersome.
  • the invention has for its object to propose a lid, the inner part of which consists of as few components as possible, which are reliable and with the least Effort to assemble.
  • the lid should be cheap to manufacture in series and have a jute closing effect over long periods of operation.
  • the locking elements arranged on the inner part are located on arms of the base plate which project freely in the form of an arc, and in the area of the opening for the passage of a central pin, lugs which protrude from the plane of the base plate and which bear against the central pin under spring prestressing are provided.
  • the inner part therefore consists of only one element, namely the base plate, which can be pushed onto the central pin and is held there by means of the tabs.
  • the arched cantilever arms ensure a high, constant spring action and consequently a tight fit of the lid.
  • the course of the bends or their free ends are adapted to the inner wall of the container so that the locking elements can be guided onto the bayonet cam track by pressing.
  • the inner part (base plate and fastening elements) is punched out of a spring steel plate in an inexpensive manner. Then you bend the locking elements.
  • spring steel it is also advantageous to use a plastic with elastic properties.
  • a cover 1 with a collar 2 has in its central area a central pin 3 which has a square shape in cross section and which is slightly conical at least in the area of its free end.
  • the lid is provided with a seal 4 which is pressed onto the top of a container 5.
  • the container 5 has, in a known manner, an inclined bayonet cam track 6, which at the end merges into a horizontal 7 with an end stop. A defined closed position is created by the horizontal 7 and the end stop, at the same time the cover moves into a latching position.
  • the inner part of the lid can be seen in more detail. It consists of a base plate 8 with an opening 9 in the central inner area. Starting from the base plate 8 are two opposing arcuate arms 10 and 11, each of which has an angled portion 12 and 13 or angled portions at its free outer ends.
  • Cams 14 which are opposite each other, project downward from the offsets 12 and 13, respectively.
  • the cams 14 serve as locking elements and are 5 in when closing the container or guided on the bayonet cam track 6.
  • tabs 15 are bent at least approximately obliquely downwards, evenly distributed over the circumference.
  • the inner part consists of a single element, e.g. a spring steel circuit board. From this board, in which the opening 9 and slots 16 are punched out to separate the arms 10 and 11 from the base plate, the tabs 15 and the locking elements 14 were bent down from the flat surface.
  • the inner part can be connected in a simple manner to the cover 1 after its production. For this purpose, it is only necessary to push the base plate 8 onto the central pin 3 from below. If there is e.g. the base plate made of a harder material such as the central pin 3, which is preferably in one piece with the cover 1, the tabs 15, which are elastic, can grip or clamp in the central pin 3. This ensures a secure connection.
  • the lid 1 is placed on the neck of the container 5, the locking elements 14 being inserted into the bayonet cam 6 of the container 5. With a slight rotation of the cover 1, the locking takes place in the usual way, a separate spring being omitted due to the elasticity or the leaf spring-like configuration of the two arms 10 and 11.
  • a vent slot 17 can be provided in the lid 1 to vent the container.
