Definitions

  • the invention relates to a closure for tubes or the like, which is equipped with a rotatable closure cap which has a central mouthpiece opening which can be closed by being displaced relative to a mandrel carried by spokes.
  • a closure of this type is known from U.S. Patent 1,877,882.
  • the thorn sits there on the neck of the tube. It is formed on a transverse ceiling, which is broken outside the cross section of the mandrel, so that material bridges remain in the form of load-bearing spokes.
  • the neck of the tube has an external thread.
  • the internal thread of a closure cap having a mouthpiece opening cooperates with this.
  • the section of the mandrel used for closing has a conical sealing surface which is opposite a matching funnel-shaped sealing surface of the mouthpiece opening. By screwing the cap on, the funnel-shaped sealing surface comes into contact with the conical sealing surface.
  • the mandrel Due to such a direct implementation of the rotary movement in the axially oriented pressing action, the mandrel can be subjected to high loads or even be torn off. This causes the tube to leak, which means a loss of quality, especially with heavily diffusing content.
  • the object of the invention is to improve a generic closure in terms of locking technology and handling, an ineffective rotation movement, ie which extends beyond the sealing seat surface, not leading to harmful implementations.
  • the closed position is more sensitive.
  • the means are simple and convenient.
  • the procedure is such that the mandrel, which is arranged such that it can be displaced in height, is in threaded engagement with the closure cap.
  • the axial locking movement takes place on an internal component.
  • the cap does not change its axial position. As a result, this no longer creates an incentive to unscrew a cap from the container or a tube by unscrewing it, as is possible in the prior art described and, following the play instinct, is enjoyed by children.
  • the height-displaceability of the mandrel brings it into the desired closed position or into the release position, whereby, for example, by continuing to rotate in the closed position, the corresponding movement no longer continues axially, but instead of increasing, noticeable resistance, it turns into a self-rotation of the mandrel, which, because of the desired one axial displacement of the mandrel in the spokes still has a certain amount of movement.
  • the mandrel practically has a floating seal that is still secure, even with unfavorable tolerance pairings. Accordingly, the training is useful that the spokes can be bent to shift the height of the mandrel.
  • a plastic with the necessary resilience is expediently used. It can even be tough-elastic plastic.
  • the counter thread is formed in a sleeve of the closure cap which continues into the mouthpiece opening.
  • the flow cross-section is also enlarged with regard to this sleeve, in that the sleeve is longitudinally slotted in the lower region.
  • the closure cap has an originality ring seated on tear-off bars at the lower edge. This enables the purchaser of the product to be convinced that the tube still contains the original content in terms of quantity and quality.
  • the closure cap be clipped over an annular shoulder of an insert.
  • the insert can be designed in the usual way as an assignment functional part, with adaptation to the respective neck of the tube. Furthermore, an advantageous embodiment is achieved by limiting the rotation between the insert and the closure cap.
  • an advantageous feature of the invention is that the insert which can be assigned to the tube by screwing is rotationally symmetrical U-shaped and carries the mandrel on an annular wall engaging in the neck of the tube and has an internal thread on its annular wall encompassing the neck for engagement in a corresponding external thread of the neck of the tube.
  • This not only provides stable support for the dispensing mechanism on the tube, but also good guidance for the part to be rotated.
  • closure V The basic components of the closure V are a closure cap 1 and an insert 3 that can be assigned to the tube 2 by screwing.
  • the tube 2 or a similar container such as a bottle, canister or the like has an upwardly directed, narrowed neck 4.
  • the latter has an external thread 5.
  • a suitable internal thread 6 of the insert 3 works together with the external thread 5 of the neck 4.
  • the insert 3 is U-shaped with rotational symmetry.
  • the neck 4 engages in the U-opening pointing in the direction of the tube 2.
  • the U-profile therefore breaks down into an annular wall 7 projecting into the opening ⁇ of the neck 4 and into an annular wall 8 encompassing the neck 4, on which the aforementioned internal thread 6 is seated.
  • the U-web of the U-profiled insert 3 forms an annular shoulder 9 which forms the end of the U-opening.
  • the latter lies with the inside sealingly on the flat front edge 10 of the neck 4.
  • the inner ring wall 7, which also projects sealingly into the opening ⁇ , is placed same level over the annular shoulder 9 upwards to just below a ceiling 11 of the closure cap 1.
  • a web collar 12 pointing in the opposite direction extends from the ceiling 11 on the inside. The web collar sealingly rests on the overhang of the ring wall 7 on the jacket wall side.
  • the lower section of the insert 3 carries a mandrel D.
  • the latter extends in the longitudinal central axis xx of the rotationally symmetrical closure V. It is directed upwards and is seated on flexible spokes 13.
  • the latter extend from the inner wall of the ring wall 7 integrally formed and have roots as well in the lateral wall of the foot of the thorn D.
  • the spokes 13 take an upward converging course; a course of curvature in this direction is also conceivable.
  • a mandrel D connected in this way can be closed in the closure V height shift.
  • a thread engagement G is used for this. This is implemented between the mandrel D and the rotatably associated closure cap 1.
  • the mandrel D has a thread 14 on its basically cylindrical outer surface, but this is only formed over a part of the circumference, in each case interrupted by a few longitudinal niches 15 as a flow cross section for the substance 16 in the tube.
  • the corresponding counter thread 17 is formed in a sleeve 18 of the cap 1.
  • Said sleeve 18 continues to pass through the medium or substance 16 to be dispensed into a central mouthpiece opening 19 of the closure cap 1 which is significantly reduced in cross section compared to the inside diameter of the sleeve.
  • the ceiling 11 tapers out centrally into a spout mouth 20.
  • the mandrel closure point is formed between the mouthpiece opening 19, which is circular in cross section, and the hollow of the sleeve 18, namely on the mandrel side through the conical sealing surface 21 of a closing cone of the mandrel D and on the closure cap side through a corresponding funnel-shaped sealing surface 22 in the transition region between the sleeve hollow and the Mouthpiece opening 19.
  • the flow cross-section is formed by the above-mentioned interruption or recess 15 of the thread 14 and also a groove 24 or a plurality of grooves 24 located in this interruption area and extending in the direction of extension of the mandrel.
  • the longitudinal grooves 24 end shortly before the one explained Locking point between mandrel D and locking cap 1. On the other hand, they completely penetrate the base of the mandrel D.
  • the spokes 13 are realized as or additionally as flat webs lying in one plane.
  • two webs are rooted in a diametrically opposed position in the inner wall of the ring wall 7 in order to run into the jacket wall of the central mandrel D offset by 90 ° via a crescent-shaped arch section 26.
  • the illustrated grooves 24 and the interruption sections of the threads 14 lie between these inlet zones.
  • the course of the arc sections can be concentric with that of the ring wall 7. A greater curvature is recommended if you want to increase the length reserve even further.
  • the spokes 13 are all implemented as flat webs such that their horizontal cross-sectional length is greater than the vertical cross-sectional height.
  • lying in one plane is meant that the connection points of all spokes 13 lie in one plane, here the ring wall side in a lower plane than the mandrel side.
  • the spoke connection is set higher in FIG. 2 in order to be able to represent it better, that is to say in a more understandable manner.
  • the closure cap 1 is clipped onto the cylindrical jacket wall of the ring wall 8 of the insert 3 serving as the guide body.
  • the clip is located near the ring shoulder 9 of the insert 3. It consists of an annular bead 27 on the closure cap side and an annular groove 28 corresponding to the cross section.
  • the groove engagement is perpendicular to the longitudinal central axis x-x.
  • the cross section of the annular bead 27 is semispherical. This and the edge edge chamfer of the shoulder facilitates the assignment of the clips between the two parts 1 and 3.
  • a rotation limitation is implemented between the insert 3 and the closure cap 1 which can be rotated thereon.
  • the latter consists in a simple manner on the cap side of two stop fingers 30 which are offset at an angle to one another and on both sides of a stationary stop block 31 seated on the annular shoulder 9 (see FIG. 4).
  • the stop block 31 effects the rotation limitation in the open position of the closure V.
  • the other rotary stop position lies behind the closed position reached and is practically only effective in the event of extreme overload.
  • a range of rotation angle can be captured in the spring system of the spokes 13. The power stored there may even be saved as a reserve favoring the shooting position.
  • closure V described is also designed such that the closure cap 1 has a tamper-evident ring 33 connected at the lower edge by means of predetermined tear-off webs 32.
  • a locking projection 35 seated on the base of the neck holds it in place when the closure cap 1 rotates, so that the tear-off webs 32 tear off when the dispenser equipped with the closure V is put into use.
  • the opening position reached according to FIG. 4 remains dependent on the rotational position. A willful backward movement of the cap 1 clockwise into the position according to FIG. 3 is required.
  • the opening position according to FIG. 4 is limited by the stop block 31 mentioned above, against which one of the fingers 30 moves. As a result, further unscrewing of the mandrel from the sleeve 18 is prevented, that is, further expansion of the spokes 13 is avoided.
  • the tube 2 only needs to be tilted in order to let the contents run out or trickle. If the tube 2 is made of collapsible material, for example, the spreading function can be supported by compressing the tube 2.
  • the closure is closed by rotating the closure cap in the opposite direction of arrow 36.
