Definitions

  • the present invention relates to a lower closure part with a pipe socket and a fastening flange arranged on the outside of the pipe socket, at least one projection being provided on the inside of the pipe socket, which serves to hold the lower closure part on a mandrel when fastened to a container wall.
  • Corresponding lower closure parts have been known for a long time and they are mainly used for plastic closures of cardboard packaging, e.g. B. for drinks or the like, in which the closure or the lower closure part is generally passed from the (later) inside of the container through an opening in the wall of the container, the closure flange coming into contact with the inner surface of the container wall and then with this is welded or glued.
  • the corresponding mandrels must be matched to the inside diameter of the corresponding lower closure parts, or more precisely to the diameter defined by the projections, in order on the one hand to hold a lower closure part securely before and during assembly, and on the other hand also to easily remove it from the assembled lower closure part to be able to be removed.
  • the projection is designed as an annular circumferential bead or lip along the lower inner edge of the pipe socket.
  • a plurality of separate, bead-like projections are provided, which are distributed over the circumference of the pipe socket on the inside thereof and in the vicinity of the lower inner edge.
  • the mandrels for holding these closures must also be changed, because a given closure size can only be held with a suitably matched mandrel, there being only little tolerance margin for holding and transporting the bottom part of the closure to ensure a mandrel, but on the other hand to be able to easily detach the mandrel from the assembled lock.
  • the change of the mandrels for the adaptation to different closure sizes is relatively time-consuming and annoying and significantly reduces the productivity in the manufacture or attachment of such closures. Even slight tolerances in the manufacture of one and the same type of closure can already lead to malfunctions during assembly, since the closure then either slides off the mandrel too easily or is held too tightly on the mandrel.
  • closure seals are provided on many such closures, which completely cover the cross-section of the pipe socket, so that only a relatively short section of the pipe socket is available below the closure seal for holding by a corresponding mandrel.
  • the present invention has for its object to provide a corresponding lower closure part, which can be held on a mandrel with a much greater tolerance.
  • the at least one projection has the shape of a web which can be bent away and which is inclined relative to the inner wall of the connecting piece at an angle which is less than 90 ° and greater than 0 °.
  • deflectable webs are provided, which are opposite the inner wall of the nozzle is inclined at an angle that is less than 90 ° and greater than 0 °. This effectively means that a much larger elastic movement path is available by bending the webs away than was usually possible by compressing or radially expanding the corresponding material.
  • the projection according to the invention in the form of a web which can be bent away and extends at an angle to the pipe socket wall, substantially larger tolerance deviations of the mandrel diameter with respect to the pipe socket diameter can be absorbed, so that even with different types of closures with slightly different pipe socket diameters, one and the same mandrel can nevertheless be used in order to do this To hold and assemble the lower part of the lock.
  • the webs expediently incline at an angle between 20 ° and 70 ° with respect to the pipe socket wall (more precisely with respect to a tangent to the pipe socket wall), an angle in the range of approximately 45 ° being most preferred.
  • the webs in the preferred embodiment of the invention can run essentially axially parallel, ie they are connected to the inner wall of the pipe socket along a substantially axially parallel line and they are designed as short, flat webs or plates, the level of which Platelets or webs also run parallel to the axis of the pipe socket.
  • the webs are connected to the wall of the pipe socket along a line inclined to the axis, for. B. along a diagonal line or else along a circumferential line.
  • the inclination of the webs in relation to the wall of the cavity is then best determined in a plane that is perpendicular to the line of attachment of the web to the wall.
  • these webs should only extend over relatively narrow angular ranges of less than 60 ° and preferably less than 30 °, in particular in the case of webs running only in the circumferential direction. If, in fact, the webs extend over a larger angular range, the curvature gives them greater rigidity and is therefore no longer easily bent away.
  • the webs are relatively easy to move if they only extend in the circumferential direction over relatively short sections or if they are attached to the pipe socket along an axially running line, they can also be provided with a greater length (measured perpendicular to their fastening line) , so that, due to this fact, there is a larger movement path for catching tolerances for the webs.
  • several, e.g. B. three corresponding webs and preferably at least six webs are provided, which are expediently distributed at equidistant angular intervals along the circumference of the pipe socket, and preferably along the lower end portion of the pipe socket.
  • FIG. 1 shows an axial section through an inventive lower part
  • FIG. 2 shows a bottom view of the lower part according to FIG. 1
  • FIG. 3 shows an enlarged detail from FIG. 2.
  • FIG. 1 shows the axial section through a lower closure part 1, consisting of a pipe socket 2 with an external thread 5 and an attachment flange 3 attached externally to the lower end of the pipe socket 2.
  • a closure seal which is also usually present and which is located in the interior of the pipe socket 2 is arranged and its cross section closes.
  • a total of three projections in the form of short webs 4 can be seen along the lower edge of the pipe socket in each representation, which, as can be seen more clearly in FIG. 2, are inclined towards the wall of the pipe socket 2.
  • a short mandrel is inserted from below into the pipe socket 2, the diameter of which is slightly smaller than the inside diameter of the pipe socket 2, the webs 4 being bent away, ie pressed in the direction of the pipe socket wall, so that the elastic restoring force causes the Web 4 the lower closure part 1 is held securely on the mandrel.
  • the lower closure part is then with the help of this dome on the inner wall of a container, for. B. a cardboard packaging brought up, which has a corresponding opening for receiving the pipe socket 2.
  • the pipe socket 2 is passed through this opening from the inside, the flange 3 abutting the inside wall of the container and being welded or glued to it.
  • the mandrel is then pulled out of the pipe socket 2 again, the flange 3 holding the lower closure part 1 to the container and in the container opening, so that the mandrel can be pulled out of the pipe socket 2 despite the frictional engagement with the easily deflectable webs 4.
  • This process generally takes place before the container is formed on a continuous material web from which the container is folded or formed after the closure has been attached.

Abstract

L'invention concerne un élément inférieur de fermeture comportant un ajutage tubulaire (2) et une bordure de fixation (3) placée sur le côté extérieur de l'ajutage tubulaire (2). Au moins une partie saillante (4) située sur le côté intérieur de l'ajutage tubulaire (2) sert à maintenir l'élément inférieur de fermeture (1) sur un mandrin enfoncé dans l'ajutage tubulaire (2), lorsqu'il est fixé à une paroi de contenant. L'objectif de l'invention est de créer un élément inférieur de fermeture pouvant être maintenu sur un mandrin avec une marge de tolérance sensiblement supérieure aux systèmes connus. A cet effet, la ou les parties saillantes (4) présentent la forme d'une nervure qui peut s'écarter de manière flexible et qui s'étend de manière inclinée en formant, par rapport à la paroi intérieure de l'ajutage tubulaire (2), un angle α qui est inférieur à 90° et supérieur à 0°.
