    Abstract: A multi-layered pressure packaging comprises a first container including a lockable neck portion followed by a body part and a bottom part, obtained from a non-foamed thermoplastic material by stretch blow molding, and a first layer at least enclosing the body part and/or bottom part of the first container. The first layer comprises foamed material, and the foamed material layer is foamed in place with an outer enclosure applied over and around the first container defining a free space in between, and foamable material introduced and foamed between the first container and the outer enclosure in the free space, obtaining the foamed material layer. A second layer is applied on the outer surface of the foamed layer for keeping the foamed layer and the first container together. Methods are provided for manufacturing a multi-layered pressure packaging according to an embodiment.

    Abstract: The invention provides a mould core and injection moulding apparatus for the production of a preform using a mould core which in the zone for defining the neck part of the preform comprises a combination of a raised portion and a shallow groove with a depth of 0.01 to 1 mm provided in the raised portion, for defining an internal attachment means in the neck of the preform. The invention also provides a preform and a container made from the preform, with internal attachment means in the neck. The internal attachment means is carried out rotation symmetrically with respect to the longitudinal axis of the preform. The combinations with an insert piece, preferably a pouring spout, flexible hose or dosing cap, have also been described. Furthermore, the invention provides an injection moulding method for the preform production and a stretch blow moulding method for the container production.

    Abstract: Method for manufacturing plastic preforms (10) by injection moulding, consisting of sub-preforms (11, 12) injected at the same time, wherein (Φ1) 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 (Φ2) 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 (Φ3) 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 (Φ4) 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 said preforms (11), with formation of integrated preforms (10) which are expelled to a discharge unit.

    Abstract translation: 用于通过注射成型制造塑料预成型件（10）的方法，其由同时注入的子预型件（11,12）组成，其中（Φ1）包含注入的复合预成型件（10）的注射模具（3） 预成型件（12）第一闭合，并且设置有一组接收构件（16）的夹具（4）设置在与模具（3）相对的待机位置（A）中; 在第二步骤（Φ2）中，打开模具（3），其中每个初级芯（33）承载注入的复合预制件（10），次级内芯（33'）承载次级内预制件（12）。 然后在待机位置（A）和接收位置（B）之间运动夹持器（4），其中喷射的预成型件（10,12）被冷却并从芯侧（31） ）通过抽吸装置（6）由夹持器（4）传送; 其中所述夹持器（4）进一步移动（Φ4）到另一操作位置（C）中，在所述另一操作位置（C）中，所述夹持器将所述接收的次级内部预制件（12）放置在相应的主芯（33）上并且继续保持所述预成型件（11） 形成一体的预成型件（10），其被排出到排出单元。
