Embodiment Construction

[0028] The present invention provides the definition of substantially coincident tear paths on opposing walls of a flexible packaging assembly made from a tearable film, such as a plastic film or a laminated film. The tear line facilitates controlled opening of the container by consumers wishing to access / obtain the contents of the container. By limiting the expansion of the opening slit to a defined path, a neat opening is obtained and the possibility of spillage, waste and mess is reduced. Such packaging components may be pouch containers, bags or the like.

[0029] The tearing path is defined by affixing tear-limiting elements in the form of pairs of barrier strips to the surface of the container wall or to the plies of material in the laminate constituting the wall. Preferably said strips are substantially parallel to each other. The barrier strips can be attached to the outer or inner surface of the container and in any combination. In a preferred embodiment, said stri...

Abstract

A wall material for a construction of a flexible container that is designed to be openable by tearing is formed by providing a flexible film for forming a wall of the container, providing a tear barrier element having greater tear resistance than the wall film, locating the element on or within the film to define a tear path thereon, and fixing the element to the film. The film is then arranged to form a flexible-walled container having opposed back and front walls, so that the tear path is spaced from at least a part of the top edge thereof and facilitates opening of the container by restricting tearing to the path defined between the strips. The tear barrier strips may be located to be fixed on the film by means of suitable adhesive or may be embedded between laminate layers of the wall material.

Description

technical field [0001] The present invention relates to a flexible packaging assembly that opens by tearing, and to a device for controlling the tear opening. The present invention provides a method of making a flexible packaging assembly to facilitate controlled tear openings. Additionally, the present invention provides a flexible packaging assembly incorporating a tear control device for controlling the opening. Background technique [0002] It is important for consumers to be able to control the opening of containers such as plastic bags, especially if the contents of the container are easily scattered when the container is broken. Means for controlling the opening direction of tearable packaging components have been proposed previously. In US Patent No. 5,186,543 there is disclosed an easy open flexible container having guide strips on its two opposing side walls and a closure strip on the top of the container. Extending from the seal strip to each guide strip are op...
