Suspension device for plastic tubes

The invention relates to a suspension device for plastic tubes with a hanger engaging the welded end of the tube, which can be hung on a wall hook or the like in such a way that the tube can be stored with its tube closure facing downwards.

In the case of metallic tubes, when the tube contents are squeezed out, the tube jacket is permanently plastically deformed in such a way that air inclusions are essentially prevented. In the case of plastic tubes, on the other hand, the elastic tube jacket essentially returns to its starting position after the squeezing pressure has ceased, so that air can be sucked in via the tube opening, the volume of which essentially corresponds to the volume of the squeezed out tube contents. If such a tube is now stored horizontally or with the tube cap facing upwards, the contents of the tube are moved away from the neck of the tube by gravity and during the subsequent squeezing process, air and air mixed with the tube contents are initially squeezed out, which results in inaccurate dosing and even can lead to splashing. In order to avoid this and to ensure that the tube neck is always filled with the tube contents until the tube is completely emptied, such plastic tubes should be stored standing on the tube head. To allow such vertical storage, the plastic tubes are generally provided with a screw having a diameter of the filled tube diameter approximately corresponding to a possible

™ to get a large footprint. Still it is

The stability of such tubes is unsatisfactory, see above

that hanging storage is preferable.

In a known suspension device of the type mentioned at the beginning, which is described in OE-OS 22 03 109 is »the hanger consists of a triangular shaped wire or plastic body, the long leg of which is comprises the crimped end of the tube and is movably held. However, such a suspension device is Can only be used for metallic tubes because the jacket of plastic tubes cannot be folded over in a permanently deformable manner is. For plastic tubes, the above-mentioned patent application proposes a double-sided, flexible one Material existing piping, the two flags of which with adhesive layers on the welded end of an art stofftube glued or in the course of the snapping process the tube are welded.

Such bonding is extremely problematic with plastics, especially because of the squeezing-out constant movement. A weld on the tube jacket requires additional or modified Sehiie & - devices and, moreover, such a suspension device is costly in terms of material and installation expensive on the tube body. It has therefore not been able to establish itself in practice.

It is also known from DE-OS 22 41 594, a To connect the tube hanger with a tube winding wrench that causes the tube to be squeezed out. From the reasons mentioned above is such a hanging device

but again only usable in connection with metallic tubes that are plastically deformable.

It is also known from DE-GMS 77 08 561 a tube-like container made of plastic, on which Mouthpiece opposite end a hanging hook is formed. Such training requires a Individual manufacture of the container by spraying and filling of the container through the squeezing opening through. With conventional tube filling machines

ζ such a container cannot be processed.

With the usual plastic tubes, the form-locking attack takes place on the laterally protruding pinch corners of the weld seam, which ensure reliable form-locking support, provided that the band encloses the tube jacket sufficiently tightly in the end area. This is guaranteed when the inside diameter of the loop is roughly the same as the outside diameter of the tube jacket hose

6 according to a further embodiment of the invention provided the Aufhangevorrichtiimg with the tube and an adhesive hook to be attached to the hand in the form of a packaging unit as a shrink pack or the like to bring to the consumer to allow the suspension to be carried out quickly and by oneself.

According to a modified embodiment, provision is also made for a suspension eyelet in the weld seam Attach the shape of a punched hole. To make such a hole with a standard wall hook To be able to produce a diameter, however, is a widening of the weld seam or a setback of this Weld seam required, which can cause certain problems with regard to the tube filling. Even In such a case, it would be desirable to use the longest possible hook so that the tube is securely held can be.

Exemplary embodiments of the invention are described below with reference to the drawing. In the drawing demonstrate:

Together with the tape loop 20, an extension 22 is formed from the film material, which after attachment protrudes on the tube jacket over the weld seam and has a hanging hole 24. This flexible extension 22 can be bent in the radial direction from the belt loop 20, so that a vertical suspension also is possible with only slightly projecting hooks.

In both cases, the packaging unit contains an adhesive hook 28 which can be attached to either hand in a self-adhesive manner and on which the tube can be hung by means of the hanger 18 in the manner shown in FIG. In the exemplary embodiment according to FIG. 4, the hanger is already weighed out on the tube body, while according to FIG. 5 it is attached as a single piece. The latter version relieves the manufacturer from manipulating the upper slide.
