Die Erfindung betrifft ein Verfahren zum Herstellen eines Multilayerproduktes aus mehreren Folienlagen, bei welchem die mehreren Folienlagen in einem Umformbereich zu dem Multilayerprodukt umgeformt werden, bei welchem hierzu die Folienlagen zusammengeführt und hierbei in Überdeckung gebracht werden, und bei welchem die sich überdeckend zusammengeführten Folienlagen gemeinsam, aber flächig voneinander lösbar zu dem Multilayerprodukt verformt werden.
摘要:
A vessel is configured to hold a product in an interior region formed in the vessel. The vessel includes an inner layer arranged to define the interior region and an outer layer. The vessel is formed using a blow-molding process in which a multi-layer parison is blow molded to form the vessel. The multi-layer parison is formed in an extrusion process in which a number of extruders are arranged to co-extrude associated inner and outer parisons to establish the multi-layer parison.

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.

摘要:
The present invention relates to a method for manufacturing a laminated container and the laminated container using the same. The method comprises: a first injection step for injecting a resin into a mold through a first extruder, wherein the resin is for forming an inner layer and outer layer; a second injection step for injecting a resin between the inner layer and outer layer into the mold through a second extruder after the first injection step, wherein the resin is for forming an intermediate layer; a molding step for forming the outer shape of the container after the second injection step; and an inner layer shrinkage step for separating the inner layer from the intermediate layer and shrinking the inner layer by exhausting the inner air of the container in a state where the opening of the container is sealed after the molding step. Accordingly, a laminated container can be manufactured with no an adhesive layer between layers, so production costs may be reduced. Since an additional post-treatment process for forming breath holes is not needed and damage to the inner layer can be checked while breath holes are formed, productivity of the laminated container can be improved.

The invention relates to a composite container (1), comprising a form-retaining outer container (2) and a flexible inner container (3) received therein, which inner container comprises a dispensing opening (4) which is mounted in a neck (5) of the outer container, wherein the inner container is further connected by an adhesive or weld connection (8) over (a part of) its periphery to the outer container. The adhesive or weld connection can take the form of an adhesive strip or a weld extending transversely of, parallel to or at a non-right angle to a longitudinal axis (L) running from the dispensing opening to an opposite bottom (9) of the container. The adhesive or weld connection can be adapted to detach in controlled manner under the influence of pressures occurring in the container. The invention further relates to a method for manufacturing a composite container, wherein the inner container is connected over (a part of) its periphery thereto by means of adhesion or welding.
