摘要： PCT No. PCT/SE89/00388 Sec. 371 Date Jan. 8, 1991 Sec. 102(e) Date Jan. 8, 1991 PCT Filed Jul. 6, 1989 PCT Pub. No. WO90/00504 PCT Pub. Date Jan. 25, 1990.A polymer composition for manufacturing containers, intermediate forms or parts thereof for improving their oxygen barrier properties is described. According to the invention the composition contains as an active component a metal compound having capacity to scavenge oxygen and consisting of a metal ion having complexing properties and a polymer to which the metal ion is combined as a complex. A method of producing said polymer composition is also described, according to which a polymer is treated with a metal compound dissolved or slurried in a volatile solvent composition during refluxing conditions for obtaining the active component having capacity to scavenge oxygen. The polymer composition in admixture with a further polymer can be molded into containers, intermediate forms or parts thereof.

摘要： Méthode et appareil servant à orienter une matière plastique amorphe. On fait passer la matière par un trou ayant une largeur inférieure à l'épaisseur de la matière plastique. Durant ce déplacement, la matière est orientée, au cours de la formation d'une zone de transition (18) entre une matière encore non orientée (plus épaisse) (16b) et une matière orientée (plus mince) (16a). La matière est déplacée à une vitesse qui a pour effet que l'énergie de cristallisation dégagée par l'orientation atteint les surfaces extérieures (14, 17) de la matière plastique à un moment où la matière se trouve déjà à l'état d'épaisseur réduite. L'appareil comprend un anneau d'étirage (50) et un mandrin (60) entre lesquels un trou est formé. Quand la matière plastique entre dans le trou, le trou a une largeur qui correspond sensiblement à l'épaisseur de la matière amorphe. La largeur du trou est réduite dans le sens du déplacement de la matière plastique de manière à être inférieure à l'épaisseur de la matière amorphe, mais supérieure à l'épaisseur de la matière orientée.

摘要： A method of disposing a container (13) of plastic material (7) to be tightly sealed by a foil or film (2). In an area for the intended attachment of the film or foil, the fixing area, the opening part of the container has a layer (11) of plastic material forming an outer surface against which, while closing the container the film or foil rests during supply of energy to the fixing area. Before closing the container and, according to the invention, oriented plastic material included in the fixing area and defined by said outer surface is heated to at least a temperature at which the orientation of the material commences to be reduced and the material is maintained at the increased temperature until the material is converted to substantially non-oriented material.

摘要： 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.

摘要： A hollow body (e.g. a container) as well as a method and an apparatus for its manufacture in which an axially directed wall of the body primarily comprises oriented and/or crystallised plastics material. A tubular preform (10d) is fixed in a circumferential region (13d) in the vicinity of the mouth edge (14d) of the preform between mechanical forming devices (30, 40), after which the devices, during continued clamping of the circumferential region, are displaced in the axial direction of the preform relative to a mandrel (50). Thus, the mandrel is displaced into the preform during simultaneous expansion thereof and the material is oriented and/or crystallised. In a preferred embodiment there is made a certain compensation of the stretching forces, which arise in the material when inserting the mandrel, by applying a force to the bottom of the preform by a bottom support (75).

摘要： The open mouth (12g) of a substantially tubular preform of orientable and/or crystallisable plastics material is shaped by supporting a tubular preform of orientable and/or crystallisable plastics material in a tubular sleeve (120) with a closed bottom of the preform resting on a bottom support (130) which is relatively displaceable in said sleeve, relatively displacing said tubular sleeve and said bottom support to axially displace the preform relative to the sleeve, applying force from the sleeve to the preform inwardly of the preform at an edge region of an open mouth of the preform to displace the edge region inwardly around the circumference of the tubular preform to provide said edge region with a reduced diametral extent compared to the diametral extent of the remainder of the tubular preform, and relatively moving a mandrel (140), which is posistioned within the sleeve and forms a circumferential gap therewith, through which gap the edge region extends, and said sleeve to fold a terminal end portion of said edge region outwardly to form an outwardly facing flange (18) on said edge region.

摘要： A method of producing a container of plastic material capable of being oriented and/or crystallised, in which a substantially tubular blank is, in at least two mutually consecutive and mutually separate shaping phases or shaping stages, reshaped into the container. The blank is reshaped into the container in that mechanical forming elements (34, 42) stretch the material in the axial direction of the blank, and in the circumferential direction of the blank. By stretching the material in each separate shaping stage to a regulated degree, there will be accumulated in the material a total stretching corresponding to the requisite stretching in order to impart to the material the desired and predetermined orientation and thereby the requisite strength properties.

摘要： Un conteneur flexible se vidant automatiquement est destiné à recevoir des solutions nutritives, des solutions administrées par perfusion, etc. Le conteneur consiste en un corps (1) ayant une partie extrême supérieure pourvue d'un dispositif de suspension (6). Le conteneur possède une partie extrême inférieure ayant un dispositif d'évacuation (4). Les parties extrêmes comprennent des dispositifs tubulaires (3, 5). Le corps (1) est formé par deux parois opposées assemblées suivant deux bords latéraux longitudinaux (9, 10). Le corps du conteneur consiste en une section intermédiaire (11) qui passe dans une section extrême supérieure (12) et dans une section extrême inférieure (13) où des portions de parois essentiellement plates (14, 16) sont assemblées l'une à l'autre par les dispositifs tubulaires (3, 5). Les bords latéraux (9, 10) sont conçus comme des lignes de plis qui permettent de réunir les parois sans établir de force résiliante au voisinage des bords latéraux. Les parties de parois (14a, b; 16a, b) forment entre elles, par paire, un angle et sont maintenues par les dispositifs tubulaire dans une position fixe proches les unes des autres, en même temps que les dispositifs tubulaires permettent de réunir les portions de parois sans créer de force résiliente au voisinage des dispositifs tubulaires. Pendant que le conteneur est vidé, les parois de celui-ci se rapprochent l'une de l'autre dans la partie supérieure du conteneur, formant ainsi une zone inversée se déplaçant vers le dispositif de vidage. La zone d'inversion en forme d'arc faisant face à la paroi opposée neutralise la pression du fluide ainsi que toute force agissant vers l'extérieur et générée dans le matériau; grâce à ces moyens, le conteneur est complètement vidé de son contenu sans que l'air n'entre à l'intérieur du conteneur.
