Definitions

  • the invention relates to a lid made of plastic for containers with a device or a system which enables easy and repeated opening and closing of containers with a cover.
  • a container lid is known from British patent specification GB 2091701. This lid has an outer flange, which by folding and overstretching the plastic material a detachable connection with the Container forms.
  • a disadvantage is the high force to be applied to the flange by means of fingers or sometimes only fingertips or additional tools.
  • the flange must be loosened or folded around the entire circumference of the container. This requires some skill and is time consuming. Resealing is limited due to the overstretching of the plastic and is no longer possible to the original size. Tightness and resilience are reduced.
  • the present invention includes a plastic lid with an opening device which avoids the disadvantages mentioned above.
  • the cover has levers and grid elements on its outer edge, which act as individual parts, connected via a pivot point.
  • the fulcrum lies in the low and safe application of force of the individual elements.
  • Lids of the present invention can be applied to containers manually and / or by machine.
  • both parts lock with the container edge 1a and the lever 4 and the bevel 3a.
  • the actual closing process takes place by axial pressure on the top surface 7 and the edge 6.
  • the grid 3 is pressed outwards. This is done with the least effort, because the division 8 allows a spring to the outside.
  • the cover surface 7 is in contact with the container 1, the grids 3 snap under the cover wall 1a and the container is sealed tightly and securely. Due to the right-angled arrangement of the lever 4 to the lever extension 5 and the wall of the lever 4 and lever extension 5 multiplied compared to the pivot point 5a, a highly resilient and tight locking position is provided. Shocks and pressures are absorbed by the stable angular shape.
  • the stable angular shape When opened, the stable angular shape, on the other hand, acts as a fixed lever shape with lever 4 and lever extension 5.
  • the pivot point 5a causes the grid 3 to pivot away when the lever 4 is pulled and / or pressed.
  • the closed position of the grid 3 is thus abandoned.
  • Removing the lid is easy and easy.
  • the curvature of the lever 4 and the lid extension 5 acts in a released and raised position as a lock.
  • the raised lever 4 and lever extension 5 both have slight internal tensile and / or compressive stresses and thereby hold themselves in the assumed position.
  • a reclosing is possible by slightly flipping it over, since when the force is exerted on the lever 4 towards the container, the grid 3, lever 4 and lever extension 5 clip over pivot point 5a and the grid 3 locks. This is also possible with square containers.
  • the arrangement of the lever 4 and lever extension 5 can be on the outer corners and / or on the long or short sides.
  • a so-called original or quality assurance is given if there are 8 thin connections 8a at the partitions are available. These are retained when the lid is opened. When moving to open the lever 4 and lever extension 5, the connections 8a break. This determines whether the lid has been removed and the container opened.
