A composite container, comprising a form-retaining outer container and a flexible inner container is presented. The inner container comprises a dispensing opening and can be mounted in a neck of the outer container, and the inner container is further connected to the outer container by an adhesive or weld connection over a portion of its periphery. The adhesive or weld connection can take the form of a ring adhesion or weld extending transversely to a central longitudinal axis of the container, or can cover the entire surface area of a defined portion of the respective inner container and outer container walls, such as, for example, the upper one-half of the container. The adhesion or weld can be substantially permanent, or alternatively, the adhesive or weld connection can be adapted to detach in controlled manner under the influence of pressures occurring in the container. Additionally, a method for manufacturing such a composite container is also presented, including forming a form-retaining outer container pre-form comprising a neck, forming a flexible inner container pre-form comprising a dispensing opening, inserting the inner container pre-form into the outer container pre-form and fixing said inner container pre-form to the neck of the outer-container pre-form. |
