    Abstract: Improved pre-forms for Flair and Flair-type applications are presented. In exemplary embodiments of the present invention, if two different materials which do not bond together are used to make a pre-form, then such a pre-form can be made by a bi- injection process, using the same mold. In such exemplary embodiments, first the outer pre-form can be fashioned, and then the inner pre-form can be molded through a center hole provided at the bottom of the outer pre-form. The two pre-forms are then connected to each other. The two materials can be different, such as PET and a polyolefin or polyamide, or for example, they can even be the same, such as PET/PET, if steps are taken to prevent their bonding during the molding of the second pre-form layer. In such a process, a non-stick coating can be sprayed on the surface that will be between the pre-forms, where the second perform will touch the first one, and after such application, the second container can be molded, also in a 2C process. The order of manufacture can be either outer then inner, or inner then outer, in various exemplary embodiments. If outer then inner, the non-stick coating can be sprayed on the inside of the first molded outer perform, followed by molding of the inner prefrom. If the reverse, the non-stick coating is sprayed on the outside of the first molded inner perform, then followed by the molding of the outer perform. The material from which the inner container is made, the degree of shrinkage it will experience relative to the outer container, and the concomitant maximum hot fill temperature it can thus support, can all be designed for a given application, use or range of uses.

    Abstract translation: 介绍了Flair和Flair型应用程序的改进前言。 在本发明的示例性实施例中，如果两个不结合在一起的不同材料用于预成型，则可以使用相同的模具通过双注射方法制备这种预成型件。 在这样的示例性实施例中，首先可以形成外部预成型件，然后可以通过设置在外部预成型件底部的中心孔来模制内部预成型件。 然后将两个预先形式相互连接。 两种材料可以是不同的，例如PET和聚烯烃或聚酰胺，或者例如它们甚至可以是相同的，例如PET / PET，如果采取步骤以防止在第二预成型件的模塑期间粘合 层。 在这样一个过程中，不粘涂层可以喷在表面之间，这个表面将处于预成型件之间，其中第二次表面将接触第一个表面，在这样的涂布之后，第二个容器也可以模制在 2C过程。 在各种示例性实施例中，制造的顺序可以是外部的，然后是内部的，或者是内部的，然后是外部的。 如果是外面的，那么不粘涂层可以喷涂在第一个模制外表面的内部，然后模制内部预成型件。 如果相反，不粘涂层喷涂在第一个模制内部表面的外部，然后是外部模塑成型。 制造内部容器的材料，其相对于外部容器将经历的收缩程度以及由此可以支撑的伴随的最大热填充温度，可以针对给定的应用，使用或使用范围进行设计。
