  • the invention also relates to a method for emptying at least one film bag via a pouring opening of a lid adapter.
  • a bucket is understood to mean a container with a circumferential cylindrical, usually slightly conically inclined side wall and an opening which typically extends over the entire top of the bucket.
  • the basic shape of the bucket which typically corresponds to the basic shape of the bottom, is arbitrary.
  • the bucket can, for example, have an oval, round, rectangular or square basic shape.
  • the adapter can, for example, a nozzle with a Have a pouring opening and a tap to empty the contents of the bag.
  • the film bag can be stored in an interior of a cardboard packaging (bag-in-box) and the adapter can be attached to an opening in the cardboard packaging in order to make the nozzle with the pouring opening accessible to an operator.

  • the bag insert has a folded-up bag in a compact folded format with a positioning and retaining collar for a bag neck, the collar having a profile that is complementary to the box opening.
  • the bag insert includes complementary mating ribs and slots on a lip of an opening in the collar and on the bag neck for receiving a torque in the documents US2012 / 248117A1 , US6454134B1 , DE3836069C1 and WO87 / 06922A1 further cover adapters are disclosed.
  • the invention is based on the object of providing a lid adapter, a lid with such a lid adapter, a container and an associated method, which facilitate the handling of foil bags that are stored in containers, for example in buckets, in particular with regard to their filling and emptying to simplify.
  • a lid adapter enables the container, in particular in the form of a bucket, to have the functionality of a hollow body, such as a canister, takes over.
  • a plurality of cover openings, into each of which a cover adapter is inserted, can be formed on the cover.
  • the number of cover adapters on a cover is, however, limited by the available area of the cover and the size of the cover adapter.
  • cover openings with different sizes and / or geometries for inserting corresponding cover adapters on one and the same cover can also be provided.

  • the lid adapter more precisely the nozzle, is adapted to the requirements of the closure. In the case of a twist lock, a thread is typically formed on the outside of the connecting piece.
  • the twist lock has a guarantee ring
  • corresponding counter bearings for opening the guarantee ring can be formed on the cover adapter, more precisely on the socket.

  • the nozzle can also be made open or closed by means of a top plate. In the closed variant, the top plate can be opened or torn off by means of a circumferential film hinge and thus on the one hand have a sealing effect, on the other hand it can indicate first use.
  • the cover adapter is preferably made of plastic.
  • the cover adapter is detachable and, in particular, loosely connected, i.e. with (little) play with the cover, more precisely with the edge of the cover opening. Due to the loose connection with the lid, an air gap remains between the lid adapter and the lid, through which air can flow into the container closed with the lid when the filling material is emptied. In this way, the filling material can typically be emptied from the foil pouch that is located in the container and attached to the lid adapter without a glug.
  • the latching element can be moved between a latching position and a release position, wherein the latching element in the latching position for reaching over an edge of the cover opening protrudes further (radially) outward beyond the connecting piece than in the release position.
  • the cover adapter can be pushed from the back of the cover through the cover opening, the locking element (s) being moved elastically in the direction of a central axis of the connecting piece into their release position. If the lid adapter reaches its fastening position when pushed through the lid, the latching element (s) moves outward into the latching position, ie they latch onto the top of the lid and overlap the lid. The latching element (s) thus counteract a vertical force which acts on the cover from above and prevents the cover adapter from being pushed out onto the back of the cover. The latching element (s) thus block, in the latching position, a downward movement of the cover adapter, that is to say in a direction opposite to the free end of the connecting piece.

  • the cover adapter can lie flat against the back of the cover with the plate-shaped area, but optionally one or more film layers of one or more film bags can also be attached between the cover adapter and the back of the cover.
  • the lid adapter is pushed through the lid opening from the back of the lid until the lid adapter has reached its fastening position in which the plate-shaped area rests flat against the back of the lid and the (at least one) latching element is in its latching position is located.
  • the cover adapter has at least one, in particular exactly one, from the Nozzle, for example from a circular edge contour of the nozzle, outwardly extending projection for engaging in a complementary shaped recess on the edge of the cover opening, or vice versa, wherein the locking element is preferably attached to the top of the projection.

  • the second foil bag 16a which serves as a pressure bag or to form a pressure cushion, from constricting the foil bag 16 to be emptied during its expansion
  • the second foil bag 16a has a bottle neck-shaped area in an area adjoining the nozzle 4a of the second lid adapter 1a Constriction 41 , which widens to form a wider filling area 42 which is further removed from the connection piece 4a of the second cover adapter 1a.
  • the film bag 16a of the second lid adapter 1a expands when it is filled, essentially starting from the bottom 21 of the container 20, so that the film bag 16 to be emptied does not constrict.
  • the container 25 shown, secured with a securing ring 24 for transport can be used, for example, for filling goods such as ketchup, mustard, etc., which are emptied via the tap 40.
  • the material of the container 20, the lid 3, the lid adapter (s) 1, 1a and the securing ring 24 is preferably plastic, in particular polyethylene, polypropylene, polyamides, PET or polyolefins.
