"Screw cap of a container"

The invention relates to a screw cap for the mouth neck of a container, in particular a pivotable one Plüssigseifenbehälters to be hung, with one in C 5 one between two concentric to the inner surface of the cap integrally formed, hollow cylindrical approaches formed by the opening with the opening and with up to a pre-§ given depth to be inserted sealingly into the annular groove muzzle neck.

A screw cap of this type is described in DE-OS 26 47 750. The known screw cap has a removal opening which opens into an annular groove on the inner surface of the cap that receives the mouth edge of the container neck. The annular groove is introduced on the inside by a sealing manner into the mouth opening of the container neck and the outside annular f bounded by a second, hollow cylindrical extension of the cap inner surface. The inner surface of the second hollow cylindrical extension can be pushed onto at least one outer annular rib surrounding the container neck near the mouth opening in a sealing manner and is provided with an internal thread near its free edge; this corresponds to an external thread on the container neck. The axial movement achieved by turning the cap in the threads relative to the container neck or its mouth edge is limited by axial stops. Since the inner annular extension of the inner surface of the cap has a significantly lower height than the outer hollow cylindrical extension, relative axial movement of the cap can be used

to the container neck a passage opening between free End of the inner hollow cylindrical extension and the mouth edge of the container neck to the annular groove and thus to the Withdrawal opening can be set.

The orifice opening required in the known container forms an interruption in the container neck edge in FIG the total wall thickness. It is compatible with conventional quay ( / Bring tools not to manufacture. It is also not possible to dose the amount withdrawn because it has been screwed up the closure of the sealing in the mouth opening to be introduced, the annular approach releases the edge of the mouth over the entire circumference.

The invention is based on the object for a container intended for lying down, in particular for a bottle, a functionally integrated one for product removal not necessarily screwable, hinged or tiltable one-piece closure, which is at low cost is producible to develop. In particular, a closure cap is to be created whose removal opening ■ '20 by rotation, preferably in a threadless coupling in a certain angle of rotation range partially or completely is to be opened. In this case, the border between the closure cap which is closed with respect to the removal opening should preferably be and open cap can be clearly assigned to a certain angle of rotation of the cap.

Furthermore, the width of the first sub-channel measured in the circumferential direction of the neck should be at least equal to the width of the removal opening measured in the circumferential direction. If the opening angle of the removal opening measured in relation to the hollow cylinder axis is approximately 60 °, it can be advantageous to extend the width of the first partial channel to an opening angle of approximately 90 °.

The second, the removal opening possibly with the The partial channel connecting the inside of the container is preferably made by shortening the inner hollow cylindrical extension in a circumferential area containing the removal opening educated. In a preferred embodiment, what happens is that the inner hollow cylindrical Approach through a cut obliquely with respect to the cylinder axis, in particular to about one half of the free one End of the approach, with a continuous transition to the full length being shortened.

Cut obliquely with respect to the cylinder axis is achieved that the opening and closing movement of the passage channel when the cap is rotated relative to the container neck continuously from zero or from a minimum to zoom in to a maximum and again down to NuIA is to be reduced when the zap is in an angular range corresponding to the opening angle of the first partial channel is rotated.

The thickness of the through-channel at the transition between the first and second, measured in the cylinder axis direction Partial channel should be at most approximately equal to the depth of the first partial channel at the head of the mouth neck and preferably formed at most approximately equal to the depth of the groove provided on the inside of the mouth neck will. When the cap is in the open position, a more even Product stream flow through the aligned channels without creating any noteworthy congestion areas.

Pur a convenient handling of the closure cap according to the invention it can finally be advantageous to measure the relative rotation of the cap and neck and thus the closed and open position of the cap limiting stop on the neck and on the wall surrounding it Provide cap. For example, it can be advantageous to have stops that limit the closed or open position between a cam on the outside of the neck and the longitudinal ends of a circumferential direction of the cylinder to form extending recess at the free end of the outer cylindrical extension. Instead of the one Two cams can also be formed there on the neck of the container; at the same time, a single one may be sufficient counter-cam connected to the cap. Such attacks can reduce the relative rotations of the closure

cap and muzzle neck are limited to certain swivel angle ranges. This may make handling easier and especially facilitates the search for certain settings.

In this context it should be pointed out that the hollow cylindrical approaches in relation to the cylinder axis measured opening angle of the removal opening, first sub-channel and circumferential width of the at the free end the outer hollow '.' Lindri approach provided recess should preferably be about 60 °, about 90 ° and at least about 180 in sequence. At this Size distribution and a radial gap width of the removal opening; of the order of magnitude of 1.0 mm can be Use as a spray cap of a liquid soap container, favorable work results can be achieved.

To connect the cap and the muzzle neck In the case of the closure according to the invention, a preli connection is preferably provided. The connection must of course allow relative rotation of the cap and neck.

The mouth neck of the container preferably has a circumferential locking cam, while the outer one is hollow-cylindrical Approach on its inner surface with a corresponding, circumferential impact abutment for the locking cam should be equipped. At the same time, it can be advantageous to use the area at the boundaries between the container neck and the inner surfaces the ring groove formed between the inner and outer hollow cylindrical approach against penetration or Secure penetration of product. Preferably, the outer surface of the inner cylindrical extension should and the inner surface of the neck of the mouth mate with one another. However, revolving cams can be provided on the outer surface of the container neck
