Carrying handle attachment

The innovation relates to a carrying handle attachment to plastic container !!, in which a carrying handle carrying console plate is mounted on the container shell.

The console plates designed as swivel handles carrying handles are prefabricated separately, and inserted in the preheated state by hand in the open blow mold in recesses provided after the blow mold halves have closed to the extruded parison, the blowing process begins and the hose lays against the inner contour of the mold , where under self-heat, the console plates welded to the outside of the inflated container. After the formation of the container, the prefabricated carrying handles are connected to the console plate. Such a method is not satisfactory. If the preheating temperature is insufficient, for example, no secure welding takes place with the container shell, so that the console plate can tear out in harsh operating conditions. The preheating is cumbersome and inserting the console plate in the designated recesses of the open blow mold not only time-consuming, but also dangerous if the positive engagement begins before the hand has moved out of the mold.

Explanation of the essence of the invention

It is the task of creating a secure carrying handle attachment to plastic containers, bypassing the Aufschweißvorganges and without handling the open blow mold with additional savings of assembly times.

This object is achieved according to the innovation that the releasably secured to the container shell, spreadable by at least one dividing joint console plate engages with a molded on its underside undercut the outer edge of a molded from the container shell mushroom-shaped projection form fit behind. This enables a mechanical carrying handle fastening in a container already formed from the blow mold. The Aufsprengvorgang is relatively short, can be made at any time, a preheating unnecessary, and with a special construction, the attachment of a combined already with the console plate carrying handle in the shortest possible time. The releasable attachment allows subsequent removal of the handle combination if necessary.

Usually, the carrying handle is mounted with a pivot pin on a bracket arranged on the bracket. In this case, according to the innovation in console plate beginning from the edge of the console, the console plate and the bearing block dividing and ending below the bearing block in the inner panel of the console plate dividing provided, the remaining between the joint end and the rim material bridge forms a Spreizscharnier for the console plate. In this embodiment, the console plate is spread laterally before its combination with the carrying handle placed on the mushroom-shaped projection of the container shell, compressed for positive engagement and secured in this position with the subsequently attached and held by the pivot pin carrying handle.

In an embodiment of the innovation are two by far next to each other, a flap between them enclosing, on

beginning at the top of the plate and reaching into the Mlttelberelch the console plate dividing joints, whose

Gap is slightly narrower in Fugonaniang than the inner diameter of the undercut circle

the Tolleruntorseite, whereby the console plate Within the joint ends over a sehn, lierförmigen transition Into the

Carrying handle passes. In this embodiment, handle and console plate hang together from the beginning and are in one operation

attached to the container.

For this purpose, the console plate is attached from below against the projection of the container shell and postponed. It lays down

the flap slightly back and then closes form-fitting with the projection together when the sliding process is vollendot. The undercut is under slight bias against the outer edge of the projection. In addition to the

Time savings in this embodiment also results in a material and weight savings. As an anti-rotation of the carrying handle attachment is on the top of the jacket projection in a corresponding Recess arranged on the underside of the console plate dipping catch rib. In the case of einstückigen hinge transition between console plate and carrying handle are advantageously locking rib and Recess arranged so that the recess connects the joint ends in the console plate together. The

This caused material weakening facilitates the pivotal movement of the flap during the assembly process.

In the drawing, embodiments of the innovation are shown, for example.

The detachably mounted on the container shell 1 console plate 4 engages behind with an integrally formed on its underside I! 'Intersection 18 (Fig. 2 and 4) form-fitting manner the outer edge of a molded from the container shell 1, mushroom-shaped Vorsprung, after he in the embodiment of FIGS. 1 and 2 before assembly with carrying handle 6 and pivot pin

7 spread apart and was attached to the projection 2.

In Koiisolenteller 4 1 and 2, a beginning of the console edge dividing joint 8 is provided in accordance with FIGS., Which also

shares the protruding from the console plate 4 bearing block 3 and then opens into a hole 9, which forms the joint end.

The material bridge between the circular end of the joint 8 and the plate edge acts as a hinge in the spreading movement

of the console plate 4.

After snapping into the positive engagement of the carrying handle 6 is placed on the bearing block 3 and with the through Bearing holes guided with bias ledings pivot pin 7 fixed. Thus, the console plate 4 in solid Plant held on the jacket projection 2. The outer legs 5 of the cross-sectionally T-shaped bearing block 3 form a Swiveling stop for the carrying handle 6, so that this at a fixed distance to the transport of a filled container Container jacket is held. From the top of the jacket projection is for preventing rotation, a locking rib 17 protruding into a corresponding Recess engages the underside of the attached console plate 4. In the embodiment according to Figures 3 and 4, two spaced apart dividing joints 10 are arranged, which from

leading upper edge of the plate into the central region of the console plate 4 and include a flap 16 between them.

The lower ends of the parting lines 10 are through the receiving channel for the indicated in phantom in FIG. 3 locking rib 17th

connected together so that the flap 16 can be easily swung out of the image plane. The distance between the upper joint openings is chosen so that the undercut ends grip when pushing the console plate 4 from below to the outer edge of the material projection 2 with bias over its circumference. The distance between them is therefore smaller than the diameter of the undercut circle or of the outer edge of the projection 2.

Below the joint ends of the console plate 4 approaches via a hinge-shaped transition 13 in the carrying handle 12, whose Pivoting movement is limited upwards by a stop 14. In both embodiments, the projection 2 is located in a trough-shaped recess of the container shell. 1
