Abstract: A method and an apparatus for producing a container (10) filled with goods (60) and possessing superior mechanical stability are disclosed. A preform (10a) which is filled with the filling goods, consists of crystallizable plastic material and comprises a bottom portion (11a) and an opening portion (13), is reformed into the container by means of a mechanical forming tool (20). On the reforming of the bottom portion, the mechanical forming tool displaces the bottom portion towards the opening portion of the preform under simultaneous temperature conditioning of the material of the bottom portion. The mechanical forming tool abuts against the bottom portion for such a length of time that the bottom portion obtains a total crystallinity of at least 15 %. An apparatus according to the invention includes a holder (50) in which the preform (10a) is received and in which the preform is retained on reforming of its bottom portion, and a mechanical forming tool (20) with an abutment surface (22) which, by means (26), is given an elevated temperature. The apparatus is included in equipment for filling of the preform with filling goods and the forming tool is disposed for the above-mentioned displacement of the bottom portion, once the preform has been supplied with filling goods and for retention of the abutment surface during a predetermined period of time at an end position of the above-mentioned displacement.

Abstract: A container (1) of orientable plastic material comprises a mouth portion (10), a container body (20), a bottom portion (21), and a connecting portion (11) located between the mouth portion and the container body. The mouth portion and the connecting portion consist of non-oriented material, while the container body (20) and the bottom portion (21) consist of material monoaxially oriented in the axial direction (22) of the container. The container is produced in that a blank (2) of substantially amorphous material is formed with a mouth portion (10) and with a material region (11a) corresponding to the connecting region (11) of the container under formation. Both the mouth portion and the material region (11a) are, in this instance, given a mechanical configuration substantially corresponding to the configuration of corresponding parts of the finished container. The blank is formed with a tube-like portion (20a) which connects to the material region (11a) and consists of substantially non-oriented material. The material in the tube-like portion (20a) is oriented in that the material is forced through a mechanical gap (30) with a minimum gap width which at most amounts to approximately half of the wall thickness of the amorphous material.

Abstract: The present invention relates to a method and an apparatus for orienting amorphous plastic material in that the material is caused to be displaced through a gap with a smallest gap width less than the material thickness of the plastic material. During such displacement, the material is oriented, under the formation of a transition zone (18) between as yet unoriented (thicker) material (16b) and oriented (thinner) material (16a). The material is displaced at a speed entailing that crystallization energy released on the orientation reaches the defining surfaces (14, 17) of the plastic material at a point in time when the material has already assumed its reduced thickness. The apparatus includes a drawing ring (50) and a mandrel (60), between which the gap is formed. When the plastic material enters into the gap, the gap is of a width which substantially corresponds to the material thickness of the amorphous material. In the direction of displacement of the plastic material, the gap width is reduced so as to be less than the material thickness of the amorphous material, but exceed the material thickness of the oriented material.

Abstract: A method and an apparatus to thermocrystallize amorphous thermoplastic material in a bottom portion (11) of a preform (10) while producing a container. By means of at least one heating device (20, 30) the plastic material is heated to an elevated temperature at which the material crystallizes thermally. The supply of energy is discontinued once the material crystallizes at a speed entailing that the thus released effect corresponds to or exceeds that effect which departs from the material undergoing crystallization. The apparatus includes a mandrel (26) having a forming surface (24) which at an increased temperature is brought into abutment against a defining surface (18) of the bottom portion. The forming surface has a curvature which deviates from the curvature of the defining surface (18) so that during the initial phase of the abutment the forming surface is abutting against the defining surface only in a central area thereof. On continued displacement of material in the bottom portion in order to form the portion the size of the central area is continuously increased until such time as substantially all thermoplastic material intended for temperature-conditioning abuts against the forming surfaces.

Abstract: A hollow multi-layer article, such as a container, is produced in an apparatus comprising a die head (10) and a number of extruders (20-23), each designated for extruding a specific material to form one or several of the layers of a multi-layer tube (40) from which the article is formed. The specific material fed to each extruder is heated to an increased temperature and is extruded through the die head to form said layers of the tube. Extruded pieces of the tube are expanded to form the article. According to the invention at least one (23) of the extruders (20-23) is fed with a plastics material having a melt flow index (MFI) different from the melt flow index of the plastics materials fed to the remaining extruders (20-22). Within the die head said material with higher melt flow index is attached to at least one of the layers formed in the die head to form at least one of the layers defining the wall of the article. By using a plastics material having a higher melt flow index for forming the inner or outer defining walls of the article an article having improved gloss is obtained.

Abstract: Crystallizable mainly amorphous thermoplastic material is crystallized at a temperature exceeding the glass transition temperature of the material (13) by subjecting the material at the elevated temperature to compressive forces. By means of these the material thickness as a rule is reduced by at least 20 %, preferably by at least 40 %. In a device for the application of the procedure a plunger (20) and a mould (30) are moved to a minimum distance at which the thermoplastic material (13) located between the plunger and the mould part is subjected to compressive forces. The plunger and/or the mould part are provided with elements (29, 39) for the setting and maintaining of a temperature specified in advance of the surfaces (23, 33) with which the plunger and the mould part respectively abut against the thermoplastic material.

Abstract: A plastics container for sterile storage of products, e.g. pastes or liquids, is provided with a closure device (11) which has an attachment section (13) and a section (12) removable along a weakening zone (14). A protective cap (25) is sealingly attached to the container. In accordance with the invention the body (1) of the container and the closure device are produced in separate pieces which are joined in a permanent tight join between the attachment section (13) and the orifice portion (6) of the container. The removable section has a longitudinal shape and is disposed to be opened at its outer portion for the formation of a temporary filling aperture which is permanently and tightly re-closed after filling. A sealing ring (23) is disposed in the vicinity of the lower edge of the protective cap between the protective cap (25) and the neck (2) of the container and prevents the passage of contaminations inwards to the region between the container neck and the protective cap of the sealed container. The original seal of the container is opened at the weakening zone (14), whereby there isformed an emptying aperture (34) which is enclosed by the attachment section (13).
