Definitions

  • the invention relates to a device for absorbing liquids, which has an interior delimited by a side wall, a floor and a mouth section and which is provided with a handle which is held with a handle asis in the region of the mouth section.
  • Such devices are typically manufactured by blow molding from pre-tempered preforms.
  • the attachment of a handle facilitates manual handling and transport, particularly in the case of larger devices.
  • preforms are made of a thermoplastic material, for example preforms made of PET (Polyethylene terephthalate), fed to different processing stations within a blow module.
  • a blowing module has a heating device and a blowing device, in the area of which the pre-tempered preform is expanded into a container by biaxial orientation. The expansion takes place with the aid of compressed air which is introduced into the preform to be expanded.
  • the procedural sequence for such an expansion of the preform is explained in DE-OS 43 40 291.
  • the preforms and the blown containers can be transported within the blowing module with the aid of different handling devices.
  • transport mandrels onto which the preforms are attached is known.
  • the moldings can also be handled with other support devices.
  • gripping tongs for handling preforms is described, for example, in FR-OS 27 20 679.
  • An expanding mandrel that can be inserted into a mouth area of the preform for holding purposes is explained in WO 95 33 616.
  • the preform has a significantly smaller shape than the container to be produced. Compressed air is therefore applied to the preform within the blowing station in order to convert it into the container to be produced.
  • the material is oriented. This means that the thin wall of the container has a very high dimensional stability, which makes the container suitable for a variety of uses.
  • the object of the present invention is to construct a device of the type mentioned in the introduction in such a way that a high level of functionality is achieved while at the same time being easy to manufacture.
  • the handle in the region of a handle end facing away from the handle base has a mounting profile which is received by a counter profile of the side wall, that the counter profile is formed by blow molding in the area of the side wall and that the mounting profile in the already formed counter profile can be introduced.
  • the combination of the handle base held in the area of the mouth section with the mounting profile accommodated in the area of the counter-profile provides a mounting of the handle that can withstand even greater loads.
  • the possibility of introducing the mounting profile into the counter profile after a blow molding manufacture of the device makes it possible to relate both a previous production step of an injection molding manufacture of a preform and the subsequent production step of blow molding low effort and therefore inexpensive and with a high throughput rate per unit time.
  • the mounting profile be positively received by the counter profile in the direction of a longitudinal axis of the handle.
  • the positive connection is realized by profiling a width of the handle transverse to the longitudinal axis of the handle.
  • the handle be positively held in a radial direction by the counter profile.
  • a simple implementation possibility is that the positive connection is realized by a cross-sectional profile of the handle and an adapted contour profile of the counter profile.
  • the positive connection is realized by a profile similar to a bayonet lock.
  • a compact embodiment is provided in that the handle base is formed in one piece with the mouth section.
  • the handle base is formed in the vicinity of a support ring.
  • the handle end be arranged pivotable relative to the handle base via a joint. Due to the pivotable arrangement, it is possible that the handle end can assume any positions relative to the handle base during the execution of the manufacturing process, thereby simplifying handling.
  • the joint is designed as a film hinge.
  • a transfer of forces from the end of the handle to the handle base is supported in that the handle base extends in the area of its extension facing the joint Has boundary surface which is inclined to a preform longitudinal axis.
  • a further possibility for realizing a form fit between the mounting profile and the counter profile is that the end of the handle is designed like a hook in the region of its extension facing away from the base of the handle.
  • the handle be made of a different material than the side wall.
  • the material in the region of the handle base is encapsulated with the material of the mouth section.
  • a disadvantageously high heat absorption of a prefabricated handle in the injection molding of the rest of the preform is avoided in that the handle as an insert at least when carrying out the injection molding process is picked up in areas and at least temporarily by a cooling cassette.

  • a boundary surface (82) of the handle end (64) facing the boundary surface (81) has an inclination corresponding to the boundary surface (81).
  • the corresponding inclinations of the boundary surfaces (81, 82) mean that, in the pivoted position shown in FIG. 12, the handle end (64) is supported vertically over the boundary surface (82) in the region of the boundary surface (81) in a working position. hereby weight forces can be better absorbed via the film hinge.
  • FIG. 13 illustrates in a perspective view modified from FIG. 10 again the design of a container (11) which is produced from the preforms according to FIGS. 11 and 12. It can be seen in particular that the contour of the handle (61) is integrated very harmoniously into the contour of the rest of the container (11).
