A method for producing a well-integrated multilayer material having a first material layer adjacent a second material layer, the second material layer being sparingly compatible with the first material layer includes binding the first material layer to the second material layer with an adhesive layer consisting essentially of 60 to 95 parts of a high viscosity binder component and 5 to 40 parts of a low viscosity binder component. The low viscosity binder component is capable of binding to the first material layer and the second material layer and the high viscosity binder component is capable of interacting with the low viscosity binder component.

Method of producing a well-integrated multilayer material

A mouth forming device for a container includes an opening section, an operating section and a supporting section which are disposed in substantially the same plane. A substantially U-shaped groove is provided between one end portion of the opening section and one end portion of the operating section. The supporting section surrounds a portion of the opening section and the operating section. The operating section is linked to and supported by the supporting section through axles. The opening section, the operating section and the supporting section are integrated through a thin wall portion and the support axles by molding. When the other end portion of the operating section is raised, the axles are twisted and the operating section rotates about the axles to close groove. Accordingly, the end portion of the opening section is pressed by the end portion of the operating section and the part of the container located beneath the opening section is opened by the opening section.

Pull tab cover

An end closure for a packaging container where the closure is of the basic type having a so called one step opening arrangement, i.e. where an outer layer and an inner layer are removed in unison or simultaneously by shaping the tearing denotations in a proper pattern. In order to provide an opening procedure giving less splash the outer layer is divided into a central part having a grip for individually removing the central part from the inner layer laying under the outer layer without being connected thereto. A circumferentially extending region all around the closure, is defined by said circumferential tearing denotation and the central part and is removable together with the inner layer inside the tearing denotation.
