Definitions

  • the invention relates to a tube closure with a tube shoulder cylindrical lower part, which has an outlet opening on one end face has, and a cap which can be applied to the lower part and which in the lower part applied condition closes the outlet opening.
  • the cap is like how toothpaste tubes are used every day very often removed from the lower part and placed on the lower part. It is therefore desirable that the removal or the application of the cap from or to the lower part can be done very quickly and easily.
  • Tube closures are known in which the lower part faces one another a thread tapering the rest of the lower part, the neck delimiting the outlet opening having.
  • a thread corresponding to the tapered neck is a small cap with a diameter.
  • the locking cap must be straight on the lower part be put on, otherwise the thread will jam and the cap cannot be properly screwed onto the lower part.
  • There a just put the cap on the lower part of one in diameter small cap is more difficult than a cap with a large diameter, one has started to change the thread to one in diameter enlarged area of the lower part, which is approximately the diameter of the tube body corresponds to apply. But it has been shown that one is also the largest Thread diameter applied to the lower part still carries the risk of Skewing is inherent. Even with a lower part designed in this way, the Only apply the cap with great care.
  • a plastic tube closure mentioned above to be designed in such a way that the closure cap can be easily and easily placed on the lower part can be applied.
  • the lower part has depressions on its circumference, which extend about a quarter of the circumference and to the axis of the lower part run at an angle of 85 to 60 °, preferably 80 to 70 °, in particular 75 °.
  • the inside of the cap has protrusions on its circumference, which engage in the depressions when the closure cap is placed on the lower part. For example, three depressions can be formed on the circumference of a lower part be.
  • the depressions can be designed as a branch channel, the one with its open End is accessible from the direction of the end face and its closed end is more distant from the front than its open end.
  • the protrusions of the cap from the direction of Front of the lower part are introduced into the depressions. Because the open ends of the depressions, because of the oblique course of the depressions, in the direction of the circumference of the lower part have a relatively large opening, the Protrusions of the cap easily and without much searching in the Introduce wells.
  • the protrusions of the cap slide on the wall of the depressions facing the end face of the lower part along, whereby the cap towards the tube body on the lower part is pulled.
  • the cap is pulled onto the lower part until the the front cover of the closure cap sits on the opening of the lower part and this closes.
  • the depressions have at its end distant from the end a smaller slope exhibiting area.
  • the slope of the depressions can be opposite in the area to increase the depressions in the rest of the area.
  • FIGS. 1 and 2 it has a cylindrical lower part 1 has a centrally arranged outlet opening 2.
  • the lower part 1 has an edge 8 by means of which the lower part 1 is connected to a tube body. To the Edge 8 is followed by an area 9 with a slightly reduced diameter, in which the lower part 1 has depressions 4 on its circumference.
  • the wells 4 extend about a quarter of the circumference. Furthermore, the run Wells 4 to the axis 5 of the lower part 1 at an angle of about 75 °.
  • the diameter of the lower part 1 tapers towards the end face of the lower part 1 down to about the size of the outlet opening 2 plus twice the wall thickness of the lower part 1.
  • the depressions 4 are designed as a puncture channel.
  • the branch channels are with their open ends 4a accessible from the direction of the end face.
  • the closed ends 4b of the sack channels 4 are more distant from the front of the lower part 1 than the open ones Ends 4a. Due to the oblique course of the recesses 4 is in the circumferential direction extending width of the open ends 4a significantly larger than the width of the Wells 4. This makes the frontal access to wells 4 very much easily possible.
  • the depressions 4 have an area at their ends which are more distant from the end face on, the slope opposite to the slope of the recesses 4 in the rest Area is.
  • a cap 3 has a front cover 3a.
  • the closure cap 3 On the front cover 3a opposite open end, the closure cap 3 has projections 6 on the inside on the circumference on.
  • the protrusions 6 are designed as cylindrical pins.
  • the arrangement of the protrusions 6 is such that they with the recesses 4 of the Lower part 1 correspond, being at such a distance from the front Cover 3a of the closure cap 3 are arranged so that the front cover 3a of the cap 3 seals the opening 2 of the lower part 1 when the Protrusions 6 are located in the area of the closed end 4b of the depressions 4.
