Definitions

  • the invention relates to a plastic closure for placement on a flange-shaped opening edge of a container and for permanent connection to it.
  • Plastic closures for closing containers of low stability are subject to high security requirements. So it must be ensured that the flange-shaped opening edge of the container does not bend when the plastic closures are placed, because otherwise there is no perfect connection between the closure and the container. Furthermore, the container must be closed so tightly that it can withstand a certain hydraulic or pneumatic internal pressure. Of importance in this context is the tightness of the closure when the container falls from a certain height; here it must be ensured that the container survives such a case; Finally, for guarantee reasons, it is desirable to connect the plastic closure to the container in such a way that tampering with the container is impossible or leads to damage to the closure.
  • the invention is therefore based on the object to provide a plastic closure of the type mentioned, which allows a largely insoluble and firm connection to the container mouth and yet without damage to one Low stability container can be placed.
  • the closure consists of a lower part and an upper part, that the lower part has a cross-sectionally U-shaped flange made of soft, flexible material for placement on the flange-shaped opening edge, and that a ring encompassing this flange on the outside smaller inner diameter than the outer diameter of the flange is provided, which is made of harder material than the U-shaped flange.
  • the invention thus takes advantage of the soft plastic materials to ensure the insertion of the plastic closure over the flange-shaped opening edge of the container without damaging it, and then provides the ring surrounding the flange on the outside as a support against unintentional opening of this flange.
  • the inner diameter of the hard ring is dimensioned such that it can be pushed over the flange-shaped opening edge and the soft U-shaped flange of the lower part surrounding it without damaging the container and in the pushed-on position due to the coordination of the diameter of the ring and flange of the outer leg of the U-shaped flange presses inwards and thereby the fixed connection between the ring-supported U-shaped flange and the flange-shaped opening edge is given.
  • the shape of the inner region of the ring and that of the outer region of the U-shaped flange can be made variable.
  • the ring can be pushed over the narrowed area specified in the area of the flange-shaped opening edge without damaging the container and, after passing through the narrowed area, bends the outer area of the U-shaped flange behind the outer boundary of the container edge.
  • the requirement can be taken into account, for example, by the ring only having a slightly smaller inner diameter than the outer diameter of the U-shaped flange, whereas the outer leg of the soft U-shaped flange is provided with an undercut on the inside, which is slight due to the ring being pushed over gig is moved further inwards.
  • the inner diameter of the ring can be significantly reduced compared to the outer diameter of the U-shaped flange, which, when the ring is slid on, leads to an extensive bending of the outer leg and, consequently, this leg need not be provided with an undercut.
  • Pushing the ring onto the outer leg of the U-shaped flange is made considerably easier if either the ring or the leg are provided with an insertion cone on the sides facing one another. Removal of the ring is prevented by the design of the ring and outer leg of the U-shaped flange.
  • the flange-shaped opening edge has a first flange section which widens conically outwards and a second flange section which adjoins it and runs essentially radially to the opening, the inner leg of the U-shaped flange having its Outside comes into contact with the first flange section.
  • the seal between the flange-shaped opening edge and the U-shaped flange of the lower part takes place essentially in the region of the flared flange section, while the outer edge of the second flange section running radially to the opening is the deflection area for the outer leg of the U-shaped Represents flange when pressing the ring.
  • the ring is formed in one piece with the upper part and is connected to the upper part via small, breakable webs. If the lower part is made of softer material and the upper part is made of harder material and the design of the upper part in relation to the flange of the lower part is selected so that the ring mentioned is formed on the upper part in a position flush with the outer peripheral surface of the flange of the lower part, then it suffices a simple push movement of a tool in the axial direction of the closure to the ring from the outside of the upper part to strip off, the webs being torn off and broken, and to slide onto the flange, which is hereby - after it had been placed on the flange-shaped opening edge of the container - fixed and held so that an expansion is no longer possible.
  • Such a two-story design of the closure takes into account the requirements of mass production, on the one hand, by providing simple shaping tools, the products, in the present case the upper part, being appropriately designed, on the other hand, the shape ensures that simple assembly movements when fitting the Plastic closure on the opening edge of the container lead to a perfect connection of the closure and container.
  • An advantageous embodiment of the invention finally provides that the insertion depth of the inner leg of the U-shaped flange corresponds approximately to the height of the first flange section of the opening edge and the portion of the lower part receiving a screw cap, stopper or the like in the region of the connection of the inner leg of the U-shaped flange engages with the adjacent web on the U-shaped flange.
  • measures have thus been created by selecting the material, shape and arrangement of the individual parts and dividing the plastic closure as a mass product in the form of two pieces, in order to be able to seal closures with a gentle force even on containers of low stability, and yet non-destructive loosening after sliding the ring) to prevent furthermore a complete dispensing of the container contents.
  • the plastic closure shown in FIGS. 1 and 2 only for a cutout area is constructed essentially rotationally symmetrically and consists of an upper part, generally designated 1, and a lower part, generally designated 2.
  • the lower part consists of soft, flexible plastic, the degree of hardness of which is selected such that placing the lower part 2 on the flange-shaped opening edge 3 of the container 4 of low stability does not deform it or damage it in any other way.
  • Polyethylene for example, is suitable as the plastic for the lower part 2.
  • the container 4 consists, for example, of tinplate, it has a circular opening (not designated in more detail) in the region of the container lid 5, which is enclosed by the flange-shaped opening edge 3.
  • This has a flange section that widens conically outwards, which consists of a first region 6a that extends almost axially with respect to the opening and a region 6b that widens more, which is followed by a further flange section 6c that extends essentially radially to the opening.
  • the lower part 2 essentially consists of a flange 7 which is approximately U-shaped in cross section, a bellows 8 adjoining it and an outlet nozzle 9 which is provided with an external thread 10.
  • the closure cap 11 forms part of the upper part 1, which also includes a two-part bracket 13, which is connected to the closure cap 11 by two connecting webs which are offset by 180 ° and are not shown, so that the latter is pivoted together after the bracket 13 has been pivoted up and raised can be moved with the dispensing nozzle 9 and the bellows 8 out of the opening of the container 4 in order to subsequently pull off the closure cap 11 from the dispensing nozzle 9 so that the contents of the container 4 can be dispensed.
  • a two-part bracket 13 which is connected to the closure cap 11 by two connecting webs which are offset by 180 ° and are not shown, so that the latter is pivoted together after the bracket 13 has been pivoted up and raised can be moved with the dispensing nozzle 9 and the bellows 8 out of the opening of the container 4 in order to subsequently pull off the closure cap 11 from the dispensing nozzle 9 so that the contents of the container 4 can be dispensed.
  • the two legs 7a and 7b of the U-shaped flange 7 of the lower part 2 are oriented in the direction of the container lid 5.
  • the leg 7b lies sealingly against the conical flange section 6a, while the free end of the flange section 6c in the region of the connection of the outer leg 7a and the web 7c connecting the legs 7a and 7b on the inside of the flange 7 is present.
  • the outer leg 7a is provided on the outside adjacent to the web 7c with an insertion cone 14 which widens from the web 7c and which is followed by an undercut 15. Inside, the outer leg 7a has a strong inner curvature 16 at the level of the insertion cone 14.
  • the upper part 1 is provided with a ring 17 which is connected to the outer wall of the brackets 13 by small, breakable webs 18 which are spaced apart on the inner circumference.
  • the ring consists of a radially extending section 17a and an axially extending section 17b, the latter being provided on the inside on its side facing the U-shaped flange 7 with an insertion cone 19 widening from the free end to section 17a and adjoining it Undercut 20 connects.
  • the smallest inside diameter of the axial section 17b is in the area of the end of the inlet cone 19, which is smaller than the smallest outer diameter of the outer leg 7a.
  • the closure with the lower part 2 is first placed on the flange-shaped opening edge 3.
  • the outer leg 7a is bent slightly outwards and in doing so guides the inner leg 7b along the flange section 6b.
  • the outer flange 7a slides with its cone reaching as far as the inner curvature 16 over the free end of the flange section 6c, furthermore the inner leg 7b comes into contact with the flange section 6a; in the fully inserted state, the inner curvature 16 finally engages behind the flange section 6c.
  • the described pushing on of the soft lower part 2 is expediently carried out by an automatic machine, the push-in plunger of which can then carry out a second movement in order to tear off the ring 17 on the outside from the upper part 1, ie from the two brackets 13, and on this occasion via the U-shaped flange 7 push.
  • the insertion cone 19 of the ring 17 made of the harder material, for example polypropylene initially slides along the outer surface of the outer leg 7a and, due to the smaller inner diameter, compresses the softer outer leg 7a in the region of the free end of the flange section 6c.
  • the cylinder jacket-shaped dispensing nozzle 9 is closed in its interior by a lid 21 which can be torn out after unscrewing the closure cap 11 via a ring (not shown in detail), in order to thus open the passage opening of the dispensing nozzle 9.
  • the ring 17 has only one axial leg 17b, which is connected directly to the brackets 13 via the webs 18.
  • the leg 17b has a much more pronounced inlet cone 19, which thus also bends the outer leg 7a much more inward when the ring 17 is pushed on, consequently this leg is also not provided with an internal curvature 16.
  • the formation of the ring 17 and the U-shaped flange 7 and the flange-shaped opening edge 3 corresponds to that shown in FIGS. 1 and 2, the embodiment differs in that no bellows part 8 is provided, but a rigid screw closure, in which the closure cap 11 is screwed directly onto the rigid dispensing nozzle 9 and with which the ring 17 is connected directly via the webs 18.
