Problems solved by technology

Since this handling process requires a great deal of precision in positioning the container in the stabilizing device, it results in stresses similar to those caused by the use of gripping jaw transfer devices, which, as we have already explained, are not essential to existing applications. coming is not good

Embodiment Construction

[0037] exist figure 1 with image 3 Above, two embodiments of the container 1 have been shown - in this case a bottle with a thick neck - by using a bottle made of thermoplastic material such as PET (polyethylene terephthalate). The preform is stretch-blow-molded. The container is preferably of HR type and for this purpose is produced by stretch blow molding inside a mould, the walls of which are heated so that the crystallization rate of the material can be increased by heat input.

[0038] The container 1 comprises at an upper end a threaded neck 2 provided with a drinking spout 3 . In extension of the neck 2 , the container 1 comprises in its upper part a shoulder 4 extended by a side wall or body 5 having a generally symmetrical shape of revolution formed around the main axis X of the container 1 .

[0039] The container 1 also comprises a bottom 6 extending to the lower end of the container 1 in the extension of the body 5 .

[0040] Such as figure 2 with 5 As cle...

Abstract

The invention relates to a plastic container (1) including a body (5) and a base (6) extending at a bottom end of the container, the body having, at the junction with the base, an outer diameter C, said container in which the base has: an annular outer seat portion (9) with a predetermined cross-dimension B such that: formula (I)I - a deformable arch (10) which extends inside the annular outer seat portion and which, in extended position, projects towards the outside of the container and defines an annular inner seat portion (14) with a predetermined cross-dimension A such that: formula (II).

Description

technical field [0001] The invention relates to the manufacture of containers such as bottles or jugs obtained by blow molding or stretch blow molding of preforms made of thermoplastic material. [0002] Conventional stretch blow molding results in bi-directional stretching (axial and radial) of the material, which provides good structural stiffness to the finished container. However, biaxial stretching results in residual stresses in the material that are released when hot-filled (especially with liquids above the material's glass transition temperature) and cause problems that may render them unsuitable for sale. deformation of the container. Background technique [0003] In order to reduce the deformation of the container during hot filling, it is known to accomplish stretch blow molding by a heat treatment called heat setting (French translation from the English term "heat set"), by which the newly formed The container, in contact with the walls of the mold, is heated ...
