Abstract: Hollow injection molded article made of plastic material, esp. preform for blow molding a container, with a wall (17) extending along axis (I), which is composed of a layer of variable thickness (?), being remarkable in that longitudinal ribs are provided in said axis direction, wherein the wall has a tooth profile of periodic nature varying periodically between a minimum and a maximum threshold value (m, resp. M) which is determined by a typical injection molding length (Ls) for said plastic material and/or characteristic ratio (?max/?min). A method of manufacturing thereof (10) by injection molding comprising forming inner and outer preforms (11, 12) with formation of an integrated composite preform (10), and apparatus for this purpose.

Abstract: This invention relates to a coated preform of a biaxially stretchable plastic material, for use in the manufacture of a container and a coated. At least one coating layer (3, . . . ) comprised of polymeric coating is on the outside of the plastic preform (10) is applied. Which is remarkable in that said coating is formed with at least a base layer (3) which is made of polymers that have similar structures, esp polar. It also relates to the corresponding method for this purpose.

Abstract: Method for manufacturing plastic preforms (10) by injection moulding, consisting of sub-preforms (11, 12) injected at the same time, wherein (?1) the injection mould (3) containing the injected composite preform (10) and secondary sub-preform (12) is 1 st closed, and a gripper (4) provided with a set of receiving members (16) is set in a standby position (A) aside from the mould (3); in a 2nd step (?2) the mould (3) is opened, wherein each primary core (33) bears an injected composite preform (10), and the secondary core (33?) a secondary inner preform (12); the gripper (4) is then driven (?3) in motion between the standby position (A) and a take-over position (B), wherein the injected preforms (10, 12) are cooled and taken over from the core side (31) by the gripper (4) by means of suction means (6); wherein the gripper (4) is further moved (?4) into a further operating position (C), in which it places the received secondary inner preforms (12) onto the respective primary cores (33) and continues to hold sai

Abstract: This invention relates to a polymer product comprising the components consisting of a polymer in form of granules; a multidimensional structure containing amphiphilic molecules, such as lipids, surfactants or polymers, wherein said polymer product has an active and/or passive oxygen or CO2 barrier, with an UV blocking activity or with potentially colouring with the incorporation of the multidimensional structure. It further relates to a method for manufacturing notably said polymer products, in particular from multidimensional aggregated components as barrier or carriers of living microbial cells and biological barriers in plastic and textile.

Abstract: Container for packaging under pressure of a filling product continuum, notably (semi-)liquid fluids, or discontinuous filling products resp, (such as foam, pastes, cream, or powders, comprising a neck section (23) with a pouring opening (24) on its top side, an adjacent sheathing section (22) forming the body of the container (1), and a bottom section (21) of the container, which is essentially composed of a plastic polymer which is closable on said top section (21) with a closure (5), remarkable In that the bottom section (21) disposed opposite said top section is closed by a separately added bottom (21) which is attached to said body (22) by means of a joint (13), and in that said body (22) is provided with a set of reinforcements (30), and a method for manufacturing it (1).

Abstract: An injection molding apparatus for manufacturing hollow objects, such as plastic e.g. multi-layered preforms, comprising an injection mold (1) with a front (2) and a rear side (3), which is composed of a clamp plate (4) on the front side (2), and a hot runner plate (5), where a manifold (6) is mounted in the hot runner plate, between which a set of injection nozzles (7) is arranged, which are each provided with a central supply duct (8), at the free end (9) whereof an injection gate (10) is provided. Said apparatus is remarkable in that said injection gate (10) is closable by means of a locking rod (11), which is movable herein to and fro through a profiled inner part (12) which is received in a holder (13) around which a heating element (14) is provided into which a primary channel (15) opens for supplying the plastic base material to the injection gate (10).

Abstract: Method for producing hydrophobic polymers, wherein a hydrophobic polymer is selected; a set of organisms is selected from among cells and/or cell products; aggregates are formed by working said cells and/or cell products in said polymers resulting in the formation of a so-called polymer-bio aggregate, wherein there is performed a new function of the thus polymer product. This invention further relates to the use of a so-called P.B.A. obtained therewith in specific applications.

Abstract: A preform adapted for being subjected to blow molding into a container is provided. The preform has a bottom (4), and a tubular wall (1) extending upwardly from the bottom (4) in an elongated manner. The part of the wall (1) opposite bottom (4) forms a pouring spout (20) with a profiled neck (3) encompassing a pouring opening. The pouring spout (20) is integral with the tubular wall (1). The spout (20) has a symmetrically rotational configuration, the neck (3) being provided with an externally extending annular projection (24) forming a first pouring no-drip rib at the opening. The rib includes a downwardly extending pouring surface which extends outwardly from the wall (1). The external profile of the neck (3) is provided with at least one further annular projection (21, 22) forming at least one second no-drip rib (21, 22). The first pouring no-drip rib and the at least second no-drip rib (21, 22) delimitate an annular recess (28) therebetween.

Abstract: Method for manufacturing plastic objects, in particular preforms, in which the raw material for manufacturing said objects is injected into a mould, in which said objects are cooled for hardening said injected raw material to a solid object and in that the manufactured objects are removed from the mould by means of two gripper elements (41, 42) and apparatus therefor.
