Definitions

  • the invention relates to a container, in particular a tube, with a membrane-sealed mouth opening and a cannula permanently attached to the mouth opening with a longitudinally axial through-opening and a closure cap releasably attached to the cannula with a needle-shaped mandrel movably guided in the through-opening of the cannula head element thickened relative to its needle part in a recess of the closure cap provided with a passage opening to the cannula is held fixed in an initial position with the possibility of axial mobility in an opening position penetrating the membrane.
  • Membrane-sealed tubes are known, for example, as adhesive packaging for cyanoacrylate adhesive. Before the first use, the membrane is pierced with a needle-shaped mandrel and thus the contents of the tube are released for emptying.
  • a generic container is known from DE-A-41 26477.
  • a cannula is captively attached to the tube mouth.
  • a cap is screwed onto the cannula.
  • the cap is provided with a needle-shaped mandrel, which is pressed into a recess of the cap to pierce the membrane.
  • the closure cap can be unscrewed and the adhesive can be removed from the tube through the cannula.
  • the cannula is then closed again by screwing on the closure cap, the needle-shaped mandrel being inserted with its needle part into the passage opening of the cannula.
  • the outlet opening of the cannula is only closed by the needle part of the mandrel located therein. Because of the usual manufacturing tolerances, the outlet opening of the cannula is not always completely sealed as a result, so that when the membrane is pierced, for which the user often holds the tube with one hand and presses the needle-shaped mandrel into the closure cap with the other hand, there is a risk is that adhesive emerges from the cannula and contaminates the outer surface of the cannula and the adjoining closure flap surfaces.
  • closure cap If the closure cap is now removed to remove the contents of the tube, there is a risk that the adhesive which has already escaped drips down and leads to undesired soiling. But there is also the problem that when the cap is screwed back on, these adhesive residues lead to the cap and cannula sticking together. When the contents of the tube are intended to be used again, the closure cap is then difficult to unscrew due to the now existing adhesive connection between the cannula and the closure cap, possibly with great effort.
  • the object of the invention is therefore to improve a generic container with regard to its ease of handling.
  • a closure element is formed on the mandrel between the head element and the needle part, which element is located in the opening penetrating the membrane. Position of the mandrel sealingly abuts the cannula outlet opening.

  • the screw cap is unscrewed, the consumer can assume that no product has yet emerged which could cause unintentional contamination, for example by dripping down.
  • the container according to the invention with a membrane-sealed mouth opening, attached cannula and closure cap is distinguished by improved handling and user-friendliness.
  • the closure element has a conical or rounded outer surface area which, in the opening position penetrating the membrane, seals against a correspondingly counter-conical or counter-rotating rounded inner wall area of the cannula outlet opening.
  • the sealing effect of the closure element is further improved in that, in the open position of the mandrel penetrating the membrane, the closure element lies sealingly against the closure cap wall surrounding the passage opening.
  • the invention provides in an embodiment that the mandrel, in its opening position penetrating the membrane, is fixed in the recess against axial movement is held.

  • the head element has a circumferential groove into which the bead engages in the starting position of the mandrel.
  • the bead serves both to fix the mandrel in the starting position and to fix it in the opening position penetrating the membrane.
  • the mandrel is made of plastic, as the invention provides in one embodiment.
  • the entire closure can then be produced in an inexpensive manner by injection molding.
  • the cannula has a cannula outlet opening which reduces the cross-sectional area of the mouth opening of the container in the longitudinal axial direction. has.
  • a collecting space is created within the cannula for — for example when the membrane is pierced for the first time — any product escaping from the container (tube), for example adhesive.
  • the area of the cannula outlet opening preferably has the smallest opening cross section of the through opening, so that in this area the sealing seat between the closure element and the cannula outlet opening can be formed on a relatively small area.

Abstract

L'invention concerne un récipient (1), notamment un tube rempli de colle, qui comporte une bouche (3) et une canule (5) à passage (6) axial, fixée imperdable au niveau de la bouche (3), ainsi qu'un capuchon de fermeture (14) fixé amovible sur la canule (5). Le capuchon (14) comporte une broche (23) se présentant sous forme d'aiguille, introduite de manière à se déplacer dans le passage (6) de la canule (5). Grâce à sa tête (22) qui est plus épaisse que sa partie aiguille (28), cette broche (23) est maintenue fixée dans une position initiale, dans une cavité (18) du capuchon (14), dont le passage (19) mène dans la canule (5), de manière à pouvoir se déplacer dans le sens axial, dans une position d'ouverture qui lui permet de perforer la membrane (4). L'invention vise à améliorer le maniement et la facilité d'utilisation de ce tube, et notamment à empêcher la colle de couler par inadvertance hors de la canule, après perforation de la membrane. A cet effet, il est prévu un élément de fermeture (29) formé au niveau de la broche (23), entre la tête (22) et la partie aiguille (28), qui s'applique de manière étanche sur l'ouverture de sortie de la canule (11) lorsque la broche (23) est en position d'ouverture permettant de perforer la membrane.
